Description

A new type of circular knife die cutting machine

Technical Field

The invention relates to the technical field of die-cutting equipment, and in particular to a novel circular knife die-cutting machine.

Background Art

Circular die cutting machine, also known as rotary machine, is commonly known as circular knife machine, hob machine or multi-station rotary die cutting machine. It is mainly used for die cutting (full cutting, half cutting), creasing and hot stamping, laminating, automatic waste discharge and other operations of some corresponding non-metallic materials, self-adhesive, EVA, double-sided adhesive, electronics, mobile phone pads, etc. The die-cut products are widely used in mobile phones, computers, LCD monitors, digital cameras, LCD backlights and other fields.

The functions of current die-cutting machines are relatively simple, and they can only realize automatic material connection and die-cutting operations for single-layer or double-layer material strips. When winding the finished material strip, due to the need to consider the coordination relationship between the finished product winding shaft and other structural components, a single winding method is usually adopted, and it can only be automatically wound in a clockwise direction, or only in a counterclockwise direction. It cannot automatically switch between clockwise and counterclockwise winding, and cannot meet a variety of processing and use requirements.

Summary of the invention

In order to solve the problems existing in the above-mentioned background technology, the present invention provides a new type of circular knife die-cutting machine, which realizes the automatic material connection and change operation and die-cutting operation of single-layer and multi-layer material strips, and ensures that the joints of each layer of film material in the multi-layer material strip are firmly connected and will not be disconnected. The finished product can be automatically switched between the two working states of clockwise automatic winding and counterclockwise automatic winding without manual intervention, and the equipment has stronger applicability.

In order to achieve the above object, the present invention adopts the following technical solutions:

The present invention provides a novel circular knife die-cutting machine, comprising a frame, wherein the front side of the frame is provided with a plurality of unwinding modules, an automatic cutting and splicing module and a die-cutting module with corresponding installation numbers and installation positions respectively, the unwinding module is used for unwinding new and old material strips respectively, the automatic cutting and splicing module is used for splicing the bonding tapes at both sides of the material heads of the new and old material strips unwound by the unwinding module into one, the die-cutting module is used for die-cutting the unwound material strips, at least one automatic stripping and splicing module is slidably positioned on the frame, the automatic stripping and splicing module can be movably positioned to the material discharge end of the automatic cutting and splicing module, the middle layer film material of the multi-layer material strip after the splicing treatment is exposed and the joints are bonded with tapes, and the outer side of the frame is provided with a waste winding module for winding up waste materials generated during the die-cutting operation and a finished product automatic winding module which can switch between clockwise winding and counterclockwise winding for the finished product materials after the die-cutting operation.

Furthermore, the finished product automatic winding module includes an installation panel, a turntable, a cutting assembly, and two tape positioning devices are provided on the front of the installation panel, at least two finished product winding shafts are installed on the front of the turntable, and a first driving assembly for driving the finished product winding shaft to freely switch between clockwise rotation and counterclockwise rotation is installed on the back of the turntable, and a second driving assembly connected to the turntable is provided on the back of the installation panel, and the second driving assembly drives the turntable to rotate clockwise or counterclockwise, and the two cutting rollers in the cutting assembly can move toward or away from each other, and can cut the finished product material transported inside, and the two tape positioning devices are located close to the edge of the turntable, and are used to stick tape on the front end of the finished material and stick the tape to the outside of the finished product winding shaft, one of the tape positioning devices cooperates with the finished product winding shaft to wind the finished material counterclockwise, and the other tape positioning device cooperates with the finished product winding shaft to wind the finished material clockwise.

The specific working principle is as follows: according to the characteristics of the finished film material, the first drive component is controlled to drive the finished film winding shaft to switch between clockwise rotation and counterclockwise rotation, thereby controlling the finished film winding shaft to perform the corresponding clockwise winding operation or counterclockwise winding operation, and the turntable is driven to rotate by the second drive component, and the finished film winding shaft on the turntable moves to the position close to the clockwise tape positioning device or the counterclockwise tape positioning device to cooperate, and the finished film material begins to be transported, passes through the cutting component, and the tape is pasted on the end of the finished film material through the tape positioning device and the tape is pasted and positioned to the outside of the finished film winding shaft, and the finished film begins to be wound. The winding operation is carried out clockwise or counterclockwise on the shaft. When the finished film material on a finished film winding shaft is wound to a specific diameter, the finished film material is cut by the cutting component, and the end of the finished film material moves and enters the corresponding tape positioning device. The tape positioning device sticks tape to the end of the finished film material and positions the tape to the outside of other empty finished film winding shafts, and the winding operation is continued on the finished film winding shaft. Subsequently, the staff operates to take down the finished film material on the finished film winding shaft that has been wound and use it as an empty finished film winding shaft. The above operation is repeated to complete the automatic winding operation without stopping the machine.

Furthermore, the tape positioning device includes a mounting frame, a tape assembly and a pressure wheel assembly, the mounting frame is arranged on the front side of the mounting panel, and a height adjustment assembly is provided on the mounting frame, the adjustment end of the height adjustment assembly is connected to the tape assembly used to stick the tape to the end of the finished film material and the pressure wheel assembly used to press the pasted tape toward and stick it to the outside of the finished product winding shaft, and the pressure wheel assembly is located close to the side of the turntable.

In the prior art, the glue is applied to the end of the finished film material by a glue coating roller, and the glue coating roller is pressed down to position the end of the finished film material to the outside of the finished winding shaft through the glue adhesion. This method has the problem that the end of the finished film material is not firmly bonded to the outside of the finished winding shaft. Under the action of the winding traction force, the end of the finished film material is easily separated from the outside of the finished winding shaft, and it is easy to cause pollution to the outside of the finished winding shaft. In this application, by designing the specific structure of the tape positioning device, the height adjustment component drives the tape assembly and the pressure wheel assembly to extend, and when the end of the finished film material passes through the tape assembly, the tape assembly adheres the tape to the end of the finished film material, and the finished film material is transported backward to the pressure wheel assembly. The wheel body in the pressure wheel assembly contacts the back of the tape, and presses and adheres the adhesive layer of the tape to the corresponding outside of the finished winding shaft, and then the height adjustment component drives the tape assembly and the pressure wheel assembly to retract, so that the finished film material can be wound normally.

Furthermore, the pressing wheel assembly includes a guide wheel unit and a pressing wheel unit, both of which are connected to the adjustment end of the height adjustment assembly, the guide wheel unit is located between the adhesive tape assembly and the pressing wheel unit, and the height adjustment assembly controls the pressing wheel in the pressing wheel unit to extend out of the mounting frame until the outer side of the pressing wheel contacts the outer side of the finished product winding shaft.

Whether to set up a guide wheel unit can be determined according to specific usage needs. When the conveying direction of the finished film material is not suitable for being directly introduced into the position where the outer side of the pressing wheel contacts the outer side of the finished product winding shaft, it is necessary to use the guide wheel and the pressing wheel to form a directional guidance for the conveying direction of the finished film material. The end of the finished film material can be smoothly introduced into the position where the outer side of the pressing wheel contacts the outer side of the finished product winding shaft. The conveying direction of the finished film material is consistent with the rotation direction of the winding shaft. As the finished product winding shaft rotates, it drives the tape at the end of the finished film material. The tape passes smoothly between the outer side of the pressing wheel and the outer side of the finished product winding shaft, and the tape is firmly attached to the outer side of the finished product winding shaft. The rotating finished product winding shaft can then carry out the winding operation of the finished film material (at this time, the pressing wheel assembly is immediately retracted without affecting the normal winding operation of the finished product winding shaft).

Furthermore, the bottom of the pressing wheel unit is installed on the wheel frame of the guide wheel unit through an elastic buffer assembly, the adhesive tape assembly is fixedly installed on the wheel frame of the guide wheel unit through a side arm, the wheel frame of the guide wheel unit is adjustably installed on a support plate, the support plate is connected to the adjustment end of the height adjustment assembly, and the guide wheel unit, the pressing wheel unit and the adhesive tape assembly can all be adjusted in position along the width direction of the finished film material.

By setting an elastic buffer component, the outer side of the pressing wheel in the pressing wheel unit cooperates with the outer side of the finished product winding shaft to form a certain pressing force. When the tape at the end of the finished film material passes between the two, it ensures that the tape is firmly bonded to the outer side of the finished product winding shaft, avoiding the tape from falling off due to loose bonding. The tape application component and the pressing wheel unit are integrated and installed on the wheel frame of the guide wheel unit. A height adjustment component (such as a screw drive component) can drive these three components to extend or retract synchronously, making it more convenient to operate. In addition, by setting a position adjustment component between the wheel frame of the guide wheel unit and the support plate, the positions of the guide wheel unit, the pressing wheel unit and the tape application component can be adjusted according to the width of the finished film material to be wound. The position adjustment component can adopt a structural component with a linear adjustment function in the prior art, such as a structure that adjusts the slide groove, the slider and the locking member.

Furthermore, the finished product automatic winding module also includes a support plate assembly, the support plate assembly includes a mounting seat, a first support plate and a second support plate, the mounting seat is arranged at the outlet end of the cutting assembly, the first support plate and the second support plate are arranged on the same side of the mounting seat, the two tape positioning devices are respectively used in conjunction with the first support plate and the second support plate, one end of the first support plate and the second support plate is located at the outlet end of the cutting assembly, and the other end extends to the corresponding tape positioning device.

Since there is a certain distance between the cutting assembly and the two tape positioning devices, a support plate assembly is required to support and guide the end of the finished film material. The end of the finished film material formed after cutting by the cutting assembly is guided and transported to the corresponding tape positioning device.

Since the equipment in the present application can automatically switch between the two working states of clockwise automatic winding and counterclockwise automatic winding, two tape positioning devices are also provided correspondingly (which can be respectively recorded as a clockwise tape positioning device and a counterclockwise tape positioning device). Therefore, a first supporting plate and a second supporting plate are also provided in the supporting plate assembly, which are used in conjunction with the two tape positioning devices. In a specific embodiment, the first supporting plate is used in conjunction with the clockwise tape positioning device, and the second supporting plate is used in conjunction with the counterclockwise tape positioning device. Specifically, according to the working state of the finished product winding shaft, if the finished product winding shaft is in the clockwise automatic winding state, the end of the finished film material formed after the cutting action of the cutting component is pulled into the first support plate under the action of the robot, and is supported and guided by the first support plate, and the end of the finished film material is transported to the clockwise tape positioning device for operation; if the finished product winding shaft is in the counterclockwise automatic winding state, the end of the finished film material formed after the cutting action of the cutting component is pulled into the second support plate under the action of the robot, and is supported and guided by the second support plate, and the end of the finished film material is transported to the counterclockwise tape positioning device for operation.

Furthermore, the first supporting plate and the second supporting plate are mounted on the mounting seat in an adjustable manner, and the first supporting plate and the second supporting plate can be adjusted in position along the width direction of the finished film material.

For finished membrane materials of different widths, the positions of the first supporting plate and the second supporting plate can be adjusted accordingly, making the equipment more adaptable.

Furthermore, the cutting assembly comprises two cutting rollers arranged side by side, the two cutting rollers are respectively mounted on the mounting panel via a first fixing seat and a second fixing seat, and the two cutting rollers can move towards or away from each other.

When the finished film material on a finished product winding shaft is wound to a specific diameter, the two cutting rollers in the cutting assembly need to cooperate to cut the finished film material. Since the finished film material is produced without stopping the machine, the finished film material is continuously transported backward. The cut finished film material needs to continue to be transported backward to another finished product winding shaft for winding. At this time, the two cutting rollers are controlled to separate without affecting the finished film material passing through the cutting assembly to be transported backward.

Furthermore, the waste winding module includes a base, a fixed frame, a plurality of waste winding shafts and a rotating drive component. The base is provided with a fixed frame, and a plurality of waste winding shafts arranged side by side are installed on the front of the fixed frame, and any three adjacent waste winding shafts are distributed in a triangle. The rotating drive component is installed on the back of the mounting frame, and the rotating drive component is drivingly connected to the end of the waste winding shaft for driving one or more corresponding waste winding shafts to rotate.

By optimizing the design of the installation positions of the multiple waste reeling shafts located on the front side of the mounting frame, specifically, any three adjacent waste reeling shafts are distributed in a triangular shape, preferably in an equilateral triangle shape, so as to avoid interference between the waste materials when they are simultaneously rolled onto the corresponding waste reeling shafts, while ensuring that each waste reeling shaft can roll up a coil of larger diameter, and at the same time reducing the overall height of the device, the overall stability of the device is better, and it is convenient for the staff to operate and remove the waste wound on the waste reeling shaft.

The waste winding module also includes a waste traction station. A plurality of waste traction stations are slidingly positioned on the top of the frame for directionally traction the waste generated by the die-cutting module to the waste winding module. The waste traction station includes a first-level traction station and a second-level traction station for use together. The rotating roller in the first-level traction station is in a position mode, and the waste is directionally pulled and transmitted to the waste winding module. The rotating roller in the second-level traction station is in a tension mode, and the waste is pulled and transmitted to the waste winding module with a constant force.

Furthermore, the fixing frame is reciprocatably mounted on the base, the moving direction of the fixing frame is along the axial direction of the waste winding shaft, and the moving displacement of the fixing frame is smaller than the axial length value of the waste winding shaft.

The existing die-cutting machine has realized the operation of automatic material change without stopping the machine. That is to say, the die-cutting operation will generate very long waste. The existing motor drives the waste reel to rotate and reel the waste. The diameter of the coil formed by a single winding on the waste reel is limited, resulting in a limited amount of waste winding on each waste reel. The staff needs to frequently operate to cut the waste and remove the waste wound to a specific diameter from the waste reel. In order to further increase the capacity of the waste reel on the waste reel, the fixed frame is set as a structure that can reciprocate along the axial direction of the waste reel. When working, the fixed frame is controlled to reciprocate along the axial direction of the waste reel, and the waste is wound evenly on the outside of the waste reel to a specific diameter, thereby increasing the waste winding amount of the waste reel.

Specifically, the length of the waste reel is n times (n≤6) the width of the waste. On the one hand, the space occupied by the device and the overall stability of the device are taken into consideration. On the other hand, the load-bearing capacity of the waste reel is limited, and it is also necessary to consider the convenience of the staff in removing the waste. Taking all factors into consideration, the length of the waste reel cannot be too long. Therefore, it is more reasonable to control the length of the waste reel within n times (n≤6) the width of the waste.

In order to avoid the situation where part of the waste is wound around the waste reel and the other part of the waste extends out of the waste reel, the reciprocating displacement of the fixed frame is controlled to be less than the axial length of the waste reel, so that the waste is completely wound around the outside of the waste reel.

Furthermore, the automatic cutting and splicing module can adopt a structural component with an automatic material splicing and changing function in the prior art. Specifically, a structure in which two splicing units cooperate can be adopted. The two splicing units can move toward or away from each other under the drive of a linear drive member. The splicing unit comprises a first outer frame. A first pressure roller, a cutting roller, a suction pressure roller and a second pressure roller are sequentially installed inside the first outer frame from top to bottom. During specific operation, the joint of the new material roll naturally hangs down between the two splicing units. When the old material roll is unwound to the point where the old material belt is about to run out and needs to be replaced, the two splicing units are controlled to move toward each other and approach each other. The new material roll begins to continuously unwind and convey the new material roll outward, and the released new and old material belts are synchronously conveyed downward. Through the rotation cooperation of the two first pressure rollers, the new and old material belts are tightly and flattened, ensuring that the cutting roller can cut the new and old material belts. The flatness of the cutting edge is checked during processing. When the end of the new material belt is conveyed to the position below the cutting roller, as the two cutting rollers rotate and cooperate, the new and old material belts are cut off by the blades on the cutting rollers at the same time, and the old material roll stops unwinding and conveying. The cutting port of the new material belt located at the top is aligned with the cutting port of the old material belt located at the bottom (that is, the joint of the new and old material belts), and when they are conveyed downward to the suction type pressure roller, the film on the suction type pressure roller is adhered to the opposite sides of the joint of the new and old material belts, and the film is adhered and pressed tightly at the joint of the new and old material belts through the rotation and cooperation of the two second pressure rollers. The new and old material belts are joined to form a whole, and then the two splicing units are controlled to move back to back and away from each other, the new material roll is fed normally, the old material roll that has stopped feeding is taken down and replaced with a new material roll, and the above steps are repeated to realize the automatic splicing function without stopping the machine.

Furthermore, the automatic peeling and laminating module includes a second outer frame, on which a conveying channel is provided for conveying the multi-layer material belt after the joining process, and a peeling assembly and at least one suction rubber roller are installed inside the second outer frame. The peeling assembly acts on the outer layer film on at least one side of the material belt in the conveying channel to peel it off, and the suction rubber roller is located below the peeling assembly to bond the tape to the joint exposed by the material belt after peeling off the outer layer film.

The existing automatic cutting and splicing module can realize the unwinding of single-layer or double-layer material strips and can perform automatic material splicing and changing operations, but this structure is not applicable to material strips with more than three layers. This is because the automatic cutting and splicing module joins the two sides of the material heads of the new and old multi-layer material strips (i.e., the outer film materials on both sides) with tape to form a whole, but the structure of the above-mentioned automatic cutting and splicing module cannot realize the sticking of tape at the joints of the middle layer film materials of the multi-layer material strips, and the bonding force between the middle layer film materials and the outer layer film materials on both sides is weak. When the material strip is transferred under the subsequent traction force, the joints of the middle layer film materials are prone to breakage. Therefore, an automatic peeling and laminating module is provided, and used in conjunction with an automatic cutting and splicing module. The automatic cutting and splicing module pre-cuts the new and old multi-layer material tapes, and joins the laminating tapes on both sides of the joints. The peeling knife in the automatic peeling and laminating module then peels off and removes the outer layer film on at least one side of the multi-layer material tape in the conveying channel, and then the tape is bonded to the joint of the middle layer film material exposed after the outer layer film of the multi-layer material tape is peeled off by the suction rubber roller below. The joint of the middle layer film material is firmly bonded, and it will not break during subsequent processing.

Furthermore, the air suction type rubber roller is a cam type structure, the protruding part of which is evenly provided with air suction holes, and the protruding part is covered with an elastic layer.

In order to ensure that the suction rubber roller can smoothly stick the tape to the joint of the middle layer membrane material exposed after the multi-layer material belt is processed by peeling off the outer layer film, and at the same time avoid the outer surface of the rotating suction rubber roller from contacting with the surface of the middle layer membrane material to cause contamination, the suction rubber roller is set to a cam structure, and the tape is adsorbed on the surface of this part through the suction holes of the protruding part. When in use, the suction rubber roller is controlled to rotate until the outer side of the protruding part contacts with the outer side of the middle layer membrane material exposed after peeling off the outer layer film, and the tape adheres to the joint of the exposed middle layer membrane material. Then the suction rubber roller rotates until the protruding part is offset and not in contact with the side of the multi-layer material belt. At this time, the surface of the suction rubber roller does not contact with the middle layer membrane material, and will not cause contamination to the surface of the middle layer membrane material.

Furthermore, two suction type rubber rollers are provided, and the two suction type rubber rollers are installed side by side in the second outer frame and are located on opposite sides of the multi-layer material belt in the conveying channel. One end of the two suction type rubber rollers is provided with gears that cooperate with each other, and the end of one of the suction type rubber rollers is driven and connected to a driving component.

Taking into account the internal installation space of the automatic stripping and laminating module and the efficiency of tape laminating, two suction rubber rollers installed side by side are arranged inside the second outer frame. When in use, the two suction rubber rollers are controlled to rotate toward each other to the outside of the two protruding parts to dock with each other, and respectively contact the two sides of the joint of the exposed middle layer film material after the outer film is stripped, and the tape adsorbed on the protruding part is adhered to the joint of the exposed middle layer film material. Then the two suction rubber rollers are rotated until the two protruding parts are staggered. At this time, the surface of the suction rubber roller does not contact the middle layer film material, and will not cause pollution to the surface of the middle layer film material. When the number of layers of the multi-layer material belt is 3, the surface of one of the suction rubber rollers does not adsorb the tape.

Specifically, the drive assembly adopts a structure in which a servo motor, a reducer and a coupling are matched. Through the above-mentioned force transmission structure design, only one set of drive assemblies can simultaneously drive the two suction rubber rollers to rotate in opposite directions, reducing the power part of one set of drive assemblies, saving costs, and making the equipment structure more compact.

Furthermore, the stripping component is a stripping knife, and the stripping knife is arranged obliquely downward toward the direction of the conveying channel, and the length direction of the stripping knife is consistent with the axial direction of the suction type rubber roller.

The peeling knife is used in conjunction with an external traction component such as a traction roller to direct the outer film out from the end of the peeling knife, thereby achieving the purpose of peeling the outer film of the multi-layer material belt. The external traction component provides traction for the peeling process of the outer film.

By tilting the stripping knife downward toward the conveying channel, the outward stripping force of the stripping knife on the outer film is moderate, and it is not easy for the end joint of the middle layer of film to be partially or completely separated due to excessive outward stripping force on the outer film.

Furthermore, the stripping knife is installed inside the second outer frame through an angle adjustment component, and the angle adjustment component drives the stripping knife to rotate to adjust the contact angle formed between the bottom end of the stripping knife and the outer side of the multi-layer material belt in the conveying channel.

In order to facilitate the adjustment of the peeling angle of the peeling knife and provide appropriate peeling force for multi-layer material strips of different textures, an additional angle adjustment component is provided, which drives the peeling knife to rotate so as to adjust the angle formed by the active end of the peeling knife and the outer side of the multi-layer material strip, thereby achieving the purpose of adjusting the outward peeling force of the peeling knife.

Furthermore, the angle adjustment assembly includes a rotating adjustment shaft and a manual adjustment piece, the stripping knife is installed on the rotating adjustment shaft, the rotating adjustment shaft is rotatably installed inside the second outer frame, a manual adjustment piece is provided on the outside of the second outer frame, and the manual adjustment piece is connected to one end of the rotating adjustment shaft.

When in use, the staff manually turns the manual adjustment member, which drives the rotation adjustment shaft to rotate, and the stripping knife rotates and is positioned to a specific position. The manual adjustment member can adopt a structural component with rotation adjustment and positioning functions in the prior art.

Furthermore, two raw material guide shafts are installed on the second outer frame. The two raw material guide shafts are respectively located at the inlet and outlet of the conveying channel. The raw material guide shafts are arranged perpendicular to the conveying direction of the multi-layer material belt.

The multi-layer raw materials after the automatic material exchange process are directed into the conveying channel through two raw material guide shafts to facilitate their stripping and tape application.

Furthermore, at least one auxiliary guide shaft is installed on the second outer frame, and the auxiliary guide shaft cooperates with the stripping assembly to strip the outer film on one side of the multi-layer material belt and guide it outward.

In actual application, if the outer layer film is a protective film, the peeled outer layer film is directly guided out by the auxiliary guide shaft, and there is no need to bond it with the middle layer film material later. If the outer layer film is a functional film, the peeled outer layer film is guided out by the auxiliary guide shaft to facilitate the peeling knife to continue the peeling operation. Then, when entering the subsequent die-cutting process, the outer layer film is bonded to the outside of the middle layer film material through the roller to form a whole.

Furthermore, the second outer frame is installed on a fixed panel at its side, and a buffer roller is installed on the fixed panel for use in conjunction with the auxiliary guide shaft to orient and guide the peeled protective film.

The peeled outer film is guided out in a certain direction through the cooperation of the auxiliary guide shaft and the buffer roller shaft.

Compared with the prior art, the present invention has the following beneficial effects:

The unwinding module and the automatic cutting and splicing module are used in coordination with each other, and the new and old material strips are respectively unwound by the unwinding module, and the old material strips are continuously unwound and transported to the die-cutting module for die-cutting operation. When the old material strip is about to be unwound, at this time, the automatic cutting and splicing module is used to cut the new and old material strips, and the laminating tapes on both sides of the material heads of the new and old material strips are joined together, so that the single-layer and multi-layer material strips can be automatically unwound continuously without stopping the machine. For material strips with more than three layers, the automatic stripping and laminating module is used in coordination with the automatic cutting and splicing module, so that the middle layer of the multi-layer material strip after the joining process is exposed and the adhesive tape is bonded at the joints, so as to ensure that the joints of the various layers of film materials in the multi-layer material strip are firmly joined and will not be disconnected under traction. According to the characteristics of the finished product, the finished product automatic winding module can be used to switch the finished product material after the die-cutting operation between the two working states of automatic clockwise winding and automatic counterclockwise winding, without the need for manual intervention, and the equipment has stronger applicability.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A novel circular knife die-cutting machine, as shown in FIG1, FIG2 and FIG4, comprises a frame 1, and the front of the frame 1 is provided with a plurality of unwinding modules 2, automatic cutting and splicing modules 3 and die-cutting modules 5, the number of which is corresponding to the number of installations and the installation positions, respectively. The unwinding module 2 is used to unwind the new and old material strips respectively, the automatic cutting and splicing module 3 is used to splice the two sides of the material heads of the new and old material strips unwound by the unwinding module 2 into one, and the die-cutting module 5 is used to perform die-cutting operations on the unwound material strips. At least one sliding positioning device is installed on the frame 1 An automatic peeling and laminating module mounting plate, on which an automatic peeling and laminating module 4 is mounted, the automatic peeling and laminating module 4 can be moved and positioned to the discharge end of the automatic cutting and splicing module 3, to expose the middle layer film material of the multi-layer material belt after the joining process and to apply adhesive tape to the joints, and a waste winding module 6 for winding up the waste generated during the die-cutting operation and a finished product automatic winding module 7 for switching between clockwise winding and counterclockwise winding of the finished material after the die-cutting operation is provided on the outside of the frame 1. The unwinding module 2 is coordinated with the automatic cutting and splicing module 3. The two unwinding shafts in the unwinding module 2 unwind the new and old material tapes respectively, and continuously unwind the old material tape to the die-cutting module 5 for die-cutting operation. When the old material tape is about to be unwound, the automatic cutting and splicing module 3 is used to cut the new and old material tapes, and the two sides of the new and old material tapes are bonded with tapes to form a whole, so that the single-layer and multi-layer material tapes can be unwound automatically and continuously without stopping the machine. For material tapes with more than three layers, The automatic peeling and laminating module 4 is used in conjunction with the automatic cutting and splicing module 3 to expose the middle layer of the multi-layer material belt after the joining process and to apply adhesive tape to the joints, thereby ensuring that the joints of the layers of film materials in the multi-layer material belt are firmly joined and will not break under traction. According to the characteristics of the finished product, the finished product automatic winding module 7 can switch between the two working states of clockwise automatic winding and counterclockwise automatic winding for the finished product material after the die-cutting operation, without the need for manual intervention, and the equipment has stronger applicability.

As shown in Fig. 2 and Fig. 3, the automatic cutting and splicing module 3 can adopt a structural component with automatic splicing and changing function in the prior art. Specifically, a structure with two splicing units 301 can be adopted. The two splicing units 301 can move toward or away from each other under the drive of a linear drive member. The splicing unit 301 includes a first outer frame 302. A first pressing roller 303, a first cutting roller 304, a suction pressing roller 305 and a second pressing roller 306 are sequentially installed inside the first outer frame 302 from top to bottom. When working, the joint of the new material roll naturally hangs down between the two splicing units 301. When the old material roll is unwound to the point where the old material belt is about to run out and needs to be replaced, the two splicing units 301 are controlled to move toward each other and approach each other. The new material roll begins to continuously unwind and convey the new material roll outward. The released new and old material belts are synchronously conveyed downward. Through the rotation cooperation of the two first pressing rollers 303, the new and old material belts are tightly and flatly processed, ensuring that the first cutting roller 3 04 To ensure the smoothness of the cutting edge when cutting the new and old material strips, after the end of the new material strip is conveyed to the position below the first cutting roller 304, as the two first cutting rollers 304 rotate and cooperate, the new and old material strips are cut by the blades on the first cutting roller 304 at the same time, and the old material roll stops unwinding and conveying outward, and the cutting port of the new material strip located at the top is aligned with the cutting port of the old material strip located at the bottom (that is, the joint of the new and old material strips), and when it is conveyed downward to the suction type pressing roller 305, the film on the suction type pressing roller 305 is adhered to the opposite sides of the joint of the new and old material strips, and the film is adhered and pressed tightly at the joint of the new and old material strips through the rotation and cooperation of the two second pressing rollers 306, and the new and old material strips are joined to form a whole, and then the two splicing units 301 are controlled to move back to back and away from each other, the new material roll is fed normally, the old material roll that has stopped feeding is taken down and replaced with a new material roll, and the above operation steps are repeated to realize the automatic splicing function without stopping the machine.

As shown in Figures 5 to 9, the automatic peeling and bonding module 4 includes a second outer frame 401, and a conveying channel 402 is opened on the second outer frame 401 for conveying the multi-layer material belt after the bonding process. A peeling component and at least one suction rubber roller 407 are installed inside the second outer frame 401. The peeling component acts on the outer film on at least one side of the material belt in the conveying channel 402 to peel it off. The suction rubber roller 407 is located below the peeling component and bonds the tape to the joint exposed by the material belt after peeling off the outer film.

The existing automatic cutting and splicing module 3 can realize the unwinding of single-layer or double-layer material strips and can perform automatic material splicing and changing operations, but this structure is not applicable to material strips with more than three layers. This is because the automatic cutting and splicing module 3 joins the two sides of the material heads of the new and old multi-layer material strips (i.e., the outer film materials on both sides) with tape to form a whole, but the structure of the above-mentioned automatic cutting and splicing module 3 cannot realize the sticking of tape at the joints of the middle layer film materials of the multi-layer material strip, and the bonding force between the middle layer film materials and the outer layer film materials on both sides is weak. When the material strip is transferred under the subsequent traction force, the joints of the middle layer film materials are prone to breakage. Therefore, an automatic peeling and laminating module 4 is provided, and used in conjunction with an automatic cutting and splicing module 3. The automatic cutting and splicing module 3 pre-cuts the new and old multi-layer material tapes, and joins the laminating tapes on both sides of the joints. The peeling knife 403 in the automatic peeling and laminating module 4 peels off and removes the outer layer film on at least one side of the multi-layer material tape in the conveying channel 402, and then the tape is bonded to the joint of the middle layer film material exposed after the outer layer film of the multi-layer material tape is peeled off by the suction rubber roller 407 below. The joint of the middle layer film material is firmly bonded, and it will not be broken during subsequent processing.

Specifically, the suction rubber roller 407 is a cam structure, and the protruding part thereof is evenly provided with suction holes 408, and the protruding part is coated with an elastic layer 409. In order to ensure that the suction rubber roller 407 can smoothly stick the adhesive tape to the joint of the middle layer film material exposed after the multi-layer material belt is subjected to the treatment of peeling off the outer film, and at the same time to avoid the outer surface of the rotating suction rubber roller 407 from contacting with the surface of the middle layer film material to cause pollution, the suction rubber roller 407 is set as a cam structure, and the adhesive tape is adsorbed on the surface of the part through the suction holes 408 of the protruding part. When in use, the suction rubber roller 407 is controlled to rotate until the outer side of the protruding part contacts with the outer side of the middle layer film material exposed after the treatment of peeling off the outer film, and the adhesive tape adheres to the joint of the exposed middle layer film material. Then, the suction rubber roller 407 rotates until the protruding part is staggered and does not contact with the side of the multi-layer material belt. At this time, the surface of the suction rubber roller 407 does not contact with the middle layer film material, and will not cause pollution to the surface of the middle layer film material.

Specifically, two suction rubber rollers 407 are provided, and the two suction rubber rollers 407 are installed side by side in the second outer frame 401 and are located on opposite sides of the multi-layer material belt in the conveying channel 402. One end of the two suction rubber rollers 407 is provided with a gear 410 that cooperates with each other, and the end of one of the suction rubber rollers 407 is connected to a driving assembly 411. Taking into account the internal installation space of the automatic stripping and laminating module 4 and the efficiency of laminating tape, two suction rubber rollers 407 installed side by side are provided inside the second outer frame 401. When in use, the two suction rubber rollers 407 are controlled to rotate toward each other to the outside of the two protruding parts to dock, and respectively contact the two sides of the joint of the exposed middle layer film material after the outer film is stripped, and the tape adsorbed on the protruding part is adhered to the joint of the exposed middle layer film material. Then, the two suction rubber rollers 407 are rotated until the two protruding parts are staggered. At this time, the surface of the suction rubber roller 407 does not contact the middle layer film material, and will not cause pollution to the surface of the middle layer film material. When the number of layers of the multi-layer material tape is 3, it is sufficient that the surface of one of the suction type rubber rollers 407 does not absorb the tape.

Specifically, the drive assembly 411 adopts a structure in which a servo motor, a reducer and a coupling are matched. Through the above-mentioned force transmission structure design, only one set of drive assemblies 411 can simultaneously drive the two suction rubber rollers 407 to rotate in opposite directions, thereby reducing the power part of one set of drive assemblies 411, saving costs and making the equipment structure more compact.

Specifically, the stripping component is a stripping knife 403, which is tilted downward toward the direction of the conveying channel 402, and the length direction of the stripping knife 403 is consistent with the axial direction of the suction rubber roller 407. The stripping knife 403 is used in conjunction with an external traction component such as a traction roller to guide the outer film out from the end of the stripping knife 403 in a directional manner, thereby achieving the purpose of stripping the outer film of the multi-layer material belt, and the external traction component provides traction for the stripping process of the outer film. By tilting the stripping knife 403 downward toward the direction of the conveying channel 402, the outward stripping force of the stripping knife 403 on the outer film is moderate, and it is not easy to cause the end joint of the intermediate film material to be partially or completely separated due to excessive outward stripping force on the outer film.

Specifically, considering the installation space inside the second outer frame 401, two installation sites for stripping knives 403 are set inside the second outer frame 401, which are respectively located on opposite sides of the conveying channel 402. If it is a three-layer raw material, only one stripping knife 403 needs to be installed to strip the outer film on one side of the three-layer raw material. If it is a four-layer raw material, since the middle layer film material has two layers, it is necessary to install two stripping knives 403 to strip the outer films on both sides of the four-layer raw material to expose the two layers of middle film materials, and then use two suction rubber rollers 407 to bond tapes on both sides of the joint of the two layers of middle film materials. For raw materials with more than four layers, two automatic stripping and bonding modules 4 are used in combination. However, three or more installation sites for stripping knives 403 can also be set inside the outer frame 607.

Specifically, the stripping knife 403 is installed inside the second outer frame 401 through an angle adjustment component 404, and the angle adjustment component 404 drives the stripping knife 403 to rotate to adjust the contact angle formed between the bottom end of the stripping knife 403 and the outer side of the multi-layer material belt in the conveying channel 402. In order to facilitate the adjustment of the stripping angle of the stripping knife 403 and provide a corresponding appropriate stripping force for multi-layer material belts of different textures, an additional angle adjustment component 404 is provided, which drives the stripping knife 403 to rotate so as to adjust the angle formed between the active end of the stripping knife 403 and the outer side of the multi-layer material belt, so as to achieve the purpose of adjusting the outward stripping force of the stripping knife 403.

Specifically, the angle adjustment assembly 404 includes a rotation adjustment shaft 405 and a manual adjustment member 406. The stripping knife 403 is mounted on the rotation adjustment shaft 405. The rotation adjustment shaft 405 is rotatably mounted inside the second outer frame 401. The second outer frame 401 is provided with a manual adjustment member 406 on the outside. The manual adjustment member 406 is connected to one end of the rotation adjustment shaft 405. When in use, the staff manually turns the manual adjustment member 406, which drives the rotation adjustment shaft 405 to rotate, and the stripping knife 403 rotates and is positioned to a specific position. The manual adjustment member 406 can adopt a structural component with rotation adjustment and positioning functions in the prior art.

Specifically, two raw material guide shafts 412 are installed on the second outer frame 401. The two raw material guide shafts 412 are respectively located at the inlet and outlet of the conveying channel 402. The raw material guide shafts 412 are arranged perpendicular to the conveying direction of the multi-layer material belt. Through the two raw material guide shafts 412, the multi-layer raw material after the automatic material connection and replacement process is directed into the conveying channel 402 to facilitate the peeling and tape application process.

Specifically, at least one auxiliary guide shaft 413 is also installed on the second outer frame 401. The auxiliary guide shaft 413 cooperates with the stripping assembly to strip the outer film on one side of the multi-layer material belt and guide it outward. In actual application, if the outer film is a protective film, the stripped outer film is directly guided out by the auxiliary guide shaft 413, and it does not need to be laminated with the intermediate film material later. If the outer film is a functional film, the stripped outer film is guided out by the auxiliary guide shaft 413, so that the stripping knife 403 can continue the stripping operation. Then, when entering the subsequent die-cutting process, the outer film is laminated to the outside of the intermediate film material through the roller to form a whole.

Specifically, the second outer frame 401 is laterally mounted on a fixed panel 414, and a buffer roller 415 is mounted on the fixed panel 414 for use in conjunction with the auxiliary guide shaft 413 to orient the peeled protective film. The auxiliary guide shaft 413 cooperates with the buffer roller 415 to orient the peeled outer layer film in a certain direction.

In actual processing, the front side of the film material after die-cutting is sometimes on the upper side and sometimes on the lower side. In order to avoid damage to the front side of the finished film material during winding, when the front side of the finished film material is on the upper side, the finished film material needs to be wound in a clockwise direction, and when the front side of the finished film material is on the lower side, the finished film material needs to be wound in a counterclockwise direction. However, in existing automatic winding devices, due to the need to consider the coordination relationship between the winding shaft and other structural components, a single winding method is usually adopted, and only clockwise automatic winding or counterclockwise automatic winding can be performed. It is impossible to automatically switch between clockwise automatic winding and counterclockwise automatic winding, and cannot meet the above-mentioned processing and use requirements.

As shown in Figures 15 to 17, the structure of the finished product automatic winding module 7 is designed in the present application. The finished product automatic winding module 7 includes an installation panel 701, and a turntable 704, a cutting component 706, and two tape positioning devices 714 are provided on the front of the installation panel 701. At least two finished product winding shafts 705 are installed on the front of the turntable 704, and a first driving component 702 for driving the finished product winding shaft 705 to switch freely between clockwise rotation and counterclockwise rotation is installed on the back of the turntable 704. A second driving component 703 connected to the turntable 704 is provided on the back of the installation panel 701. The second driving component 703 drives the turntable 704 to rotate clockwise or counterclockwise. The turntable 706 rotates clockwise, and the two second cutting rollers 707 in the cutting assembly 706 can move toward or away from each other, so as to cut the finished material transported inside. The two tape positioning devices 714 are located near the edge of the turntable 704, and are used to stick tape on the front side of the end of the finished material and position the tape to the outside of the finished product winding shaft 705. One of the tape positioning devices 714 cooperates with the finished product winding shaft 705 to wind the finished material clockwise, which is recorded as the clockwise tape positioning device 715, and the other tape positioning device 714 cooperates with the finished product winding shaft 705 to wind the finished material counterclockwise, which is recorded as the counterclockwise tape positioning device 716.

The specific working principle is as follows: according to the characteristics of the finished film material, the first drive component 702 is controlled to drive the finished product winding shaft 705 to switch between clockwise rotation and counterclockwise rotation, so as to control the finished product winding shaft 705 to perform the corresponding clockwise winding operation or counterclockwise winding operation, and the turntable 704 is driven to rotate by the second drive component 703, and the finished product winding shaft 705 on the turntable 704 moves to the position close to the clockwise tape positioning device 715 or the counterclockwise tape positioning device 716 for cooperation, and the finished film material begins to be transported, passes through the cutting component 706, and the tape positioning device 714 is used to stick the tape to the end of the finished film material and stick the tape to the outside of the finished product winding shaft 705, and then starts to be The finished product winding shaft 705 is wound up in a clockwise or counterclockwise direction. When the finished film material on a finished product winding shaft 705 is wound up to a specific diameter, the finished film material is cut by the cutting assembly 706. The end of the finished film material moves and enters the corresponding tape positioning device 714. The tape positioning device 714 adheres tape to the end of the finished film material and positions the tape to the outside of another empty finished product winding shaft 705. The winding operation is continued on the finished product winding shaft 705. Subsequently, the staff member operates to take down the finished film material on the finished product winding shaft 705 that has been wound up, and uses it as an empty finished product winding shaft 705. The above operation is repeated to complete the automatic winding operation without stopping the machine.

Specifically, as shown in Figure 19, the tape positioning device 714 includes a mounting frame 717, a tape assembly 720 and a pressure wheel assembly 721. The mounting frame 717 is arranged on the front of the mounting panel 701. The mounting frame 717 is provided with a height adjustment assembly 718. The adjustment end of the height adjustment assembly 718 is connected to the tape assembly 720 for sticking the tape to the end of the finished film material and the pressure wheel assembly 721 for pressing the stuck tape to and sticking it to the outside of the finished product winding shaft 705. The pressure wheel assembly 721 is located close to the turntable 704.

In the prior art, glue is applied to the end of the finished film material by a glue coating roller, and the glue coating roller is pressed down to position the end of the finished film material to the outside of the finished winding shaft 705 through the glue adhesion. In this method, the end of the finished film material is not firmly connected to the outside of the finished winding shaft 705. Under the action of the winding traction force, the end of the finished film material is easily separated from the outside of the finished winding shaft 705, and the outside of the finished winding shaft 705 is easily contaminated. In the present application, the specific structure of the tape positioning device 714 is designed, and the height adjustment component 718 is used to drive the tape assembly 720 and the pressure wheel assembly 721 to extend. When the end of the finished film material passes through the tape assembly 720, the tape assembly 720 sticks the tape to the end of the finished film material, and the finished film material is transported backward to the pressure wheel assembly 721. The wheel body in the pressure wheel assembly 721 contacts the back of the tape, and presses and sticks the adhesive layer of the tape to the corresponding outer side of the finished product winding shaft 705. Then, the height adjustment component 718 drives the tape assembly 720 and the pressure wheel assembly 721 to retract, and the finished film material can be wound up normally.

Specifically, as shown in Figure 18, the pressing wheel assembly 721 includes a guide wheel unit 722 and a pressing wheel unit 723, and the guide wheel unit 722 and the pressing wheel unit 723 are both connected to the adjustment end of the height adjustment assembly 718. The guide wheel unit 722 is located between the adhesive tape assembly 720 and the pressing wheel unit 723. The height adjustment assembly 718 controls the pressing wheel in the pressing wheel unit 723 to extend out of the mounting frame 717 until the outer side of the pressing wheel contacts the outer side of the finished product winding shaft 705. The guide wheel unit 722 may be provided based on specific usage needs. When the conveying direction of the finished film material is not suitable for being directly introduced into the position where the outer side of the pressing wheel contacts the outer side of the finished product winding shaft 705, it is necessary to use the guide wheel and the pressing wheel to form a directional guidance for the conveying direction of the finished film material. The end of the finished film material can be smoothly introduced into the position where the outer side of the pressing wheel contacts the outer side of the finished product winding shaft 705. The conveying direction of the finished film material is consistent with the rotation direction of the winding shaft. As the finished product winding shaft 705 rotates, it drives the tape at the end of the finished film material. The tape passes smoothly between the outer side of the pressing wheel and the outer side of the finished product winding shaft 705, and the tape is firmly attached to the outer side of the finished product winding shaft 705. The rotating finished product winding shaft 705 can then start the winding operation of the finished film material (at this time, the pressing wheel assembly 721 is immediately retracted without affecting the normal winding operation of the finished product winding shaft 705).

Specifically, the bottom of the pressing wheel unit 723 is installed on the wheel frame of the guide wheel unit 722 through the elastic buffer component 724, and the adhesive tape assembly 720 is fixedly installed on the wheel frame of the guide wheel unit 722 through the side arm. The wheel frame of the guide wheel unit 722 is adjustable and installed on the support plate 719. The support plate 719 is connected to the adjustment end of the height adjustment component 718. The guide wheel unit 722, the pressing wheel unit 723 and the adhesive tape assembly 720 can all be adjusted along the width direction of the finished film material. By setting the elastic buffer component 724, the outer side of the pressing wheel in the pressing wheel unit 723 cooperates with the outer side of the finished product winding shaft 705 to form a certain pressing force. When the adhesive tape at the end of the finished film material passes between the two, it is ensured that the adhesive tape is firmly bonded to the outer side of the finished product winding shaft 705, avoiding the situation where the adhesive tape falls off due to loose bonding. The adhesive tape assembly 720 and the pressing wheel unit 723 are integrated and installed on the wheel frame of the guide wheel unit 722. The three components can be driven to extend or retract synchronously through a height adjustment assembly 718 (such as a screw drive assembly 411), which makes it easier to operate. In addition, by setting a position adjustment assembly between the wheel frame of the guide wheel unit 722 and the support plate 719, the positions of the guide wheel unit 722, the pressing wheel unit 723 and the adhesive tape assembly 720 can be adjusted according to the width of the finished film material to be rolled. The position adjustment assembly can adopt a structural assembly with a linear adjustment function in the prior art, such as a structure that adjusts the slide groove, the slider and the locking member.

Specifically, the finished product automatic winding module 7 also includes a support plate assembly 710. As shown in Figure 21, the support plate assembly 710 includes a mounting seat 711, a first support plate 712 and a second support plate 713. The mounting seat 711 is arranged at the outlet end of the cutting assembly 706, and the first support plate 712 and the second support plate 713 are arranged on the same side of the mounting seat 711. Two tape positioning devices 714 are respectively used in conjunction with the first support plate 712 and the second support plate 713. One end of the first support plate 712 and the second support plate 713 are located at the outlet end of the cutting assembly 706, and the other ends extend to the corresponding tape positioning devices 714.

Since there is a certain distance between the cutting assembly 706 and the two adhesive tape positioning devices 714, the support plate assembly 710 is required to support and guide the end of the finished film material, and the end of the finished film material formed after the cutting action of the cutting assembly 706 is directed and guided to be transported to the corresponding adhesive tape positioning device 714. Since the device in this application can automatically switch between the two working states of clockwise automatic winding and counterclockwise automatic winding, two adhesive tape positioning devices 714 (which can be respectively recorded as clockwise adhesive tape positioning devices 715 and counterclockwise adhesive tape positioning devices 716) are also provided accordingly, therefore, the first support plate 712 and the second support plate 713 are also provided in the support plate assembly 710, which are used in conjunction with the two adhesive tape positioning devices 714. In a specific embodiment, the first support plate 712 is used in conjunction with the clockwise adhesive tape positioning device 715, and the second support plate 713 is used in conjunction with the counterclockwise adhesive tape positioning device 716. Specifically, according to the working state of the finished product winding shaft 705, if the finished product winding shaft 705 is in the clockwise automatic winding state, the end of the finished film material formed after the cutting action of the cutting component 706 is pulled into the first supporting plate 712 under the action of the robot, and the end of the finished film material is transported to the clockwise tape positioning device 715 for operation after being supported and guided by the first supporting plate 712; if the finished product winding shaft 705 is in the counterclockwise automatic winding state, the end of the finished film material formed after the cutting action of the cutting component 706 is pulled into the second supporting plate 713 under the action of the robot, and the end of the finished film material is transported to the counterclockwise tape positioning device 716 for operation after being supported and guided by the second supporting plate 713.

Specifically, the first support plate 712 and the second support plate 713 are mounted on the mounting seat 711 in an adjustable manner, and the first support plate 712 and the second support plate 713 can be adjusted in position along the width direction of the finished film material. For finished film materials of different widths, the positions of the first support plate 712 and the second support plate 713 can be adjusted accordingly, and the applicability of the device is stronger.

Specifically, as shown in FIG. 20 , the cutting assembly 706 includes two second cutting knife rollers 707 arranged side by side. The two second cutting knife rollers 707 are respectively installed on the installation panel 701 through the first fixing seat 708 and the second fixing seat 709. The two second cutting knife rollers 707 can move toward or away from each other. When the finished film material on a finished film winding shaft 705 is wound to a specific diameter, the two second cutting knife rollers 707 in the cutting assembly 706 need to cooperate to cut the finished film material. Since the finished film material is produced without stopping the machine, the finished film material is continuously transported backwards. The cut finished film material needs to continue to be transported backwards to another finished film winding shaft 705 for winding. At this time, the two second cutting knife rollers 707 are controlled to separate, which does not affect the finished film material passing through the cutting assembly 706 and being transported backwards.

As shown in Figures 10 to 14, the waste winding module 6 includes a base 601, a fixed frame 602, a plurality of waste winding shafts 603 and a rotating drive member 604. A fixed frame 602 is provided on the base 601. A plurality of waste winding shafts 603 arranged side by side are installed on the front of the fixed frame 602. Any three adjacent waste winding shafts 603 are distributed in a triangle. A rotating drive member 604 is installed on the back of the mounting frame 717. The rotating drive member 604 is drivingly connected to the end of the waste winding shaft 603 for driving one or more corresponding waste winding shafts 603 to rotate.

By optimizing the design of the installation positions of the multiple waste reeling shafts 603 located on the front side of the mounting frame 717, specifically, any three adjacent waste reeling shafts 603 are distributed in a triangular shape, preferably in an equilateral triangle shape, so as to avoid interference between the waste materials when they are simultaneously rolled onto the corresponding waste reeling shafts 603, while ensuring that each waste reel 603 can roll up a coil of larger diameter. At the same time, the overall height of the device is reduced, and the overall stability of the device is better, which makes it convenient for the staff to operate and remove the waste wound on the waste reel 603.

The waste winding module 6 also includes a waste traction station 611. A plurality of waste traction stations 611 are slidingly positioned on the top of the frame 1 for directionally traction of the waste generated by the die-cutting module 5 to the waste winding module 6. The waste traction station 611 includes a first-level traction station 612 and a second-level traction station 613 for use together. The rotating roller in the first-level traction station 612 is in a position mode, and the waste is directionally pulled and transmitted to the waste winding module 6. The rotating roller in the second-level traction station 613 is in a tension mode, and the waste is pulled and transmitted to the waste winding module 6 with a constant force.

Specifically, the fixed frame 602 is reciprocatingly mounted on the base 601 , the moving direction of the fixed frame 602 is along the axial direction of the waste winding shaft 603 , and the moving displacement of the fixed frame 602 is smaller than the axial length value of the waste winding shaft 603 .

The existing die-cutting machine has realized the operation of automatically changing materials without stopping the machine. That is to say, very long waste materials will be generated during the die-cutting operation. The existing motor drives the waste reel 603 to rotate and reel the waste materials. The diameter of the coil formed by a single winding on the waste reel 603 is limited, resulting in a limited amount of waste material winding on each waste reel 603. The staff needs to frequently operate to cut the waste materials and remove the waste materials wound to a specific diameter from the waste reel 603. In order to further increase the capacity of the waste reel 603 to reel in the waste reel, the fixed frame 602 is set to a structure that can reciprocate along the axial direction of the waste reel 603. When working, the fixed frame 602 is controlled to reciprocate along the axial direction of the waste reel 603, and the waste is wound evenly on the outside of the waste reel 603 to a specific diameter, thereby increasing the amount of waste material winding on the waste reel 603.

Specifically, the length of the waste reel 603 is n times (n≤6) the width of the waste. On the one hand, the space occupied by the device and the overall stability of the device are taken into consideration. On the other hand, the load-bearing capacity of the waste reel 603 is limited, and it is also necessary to take into account the convenience of the staff in removing the waste. Taking all factors into consideration, the length of the waste reel 603 cannot be too long. Therefore, it is more reasonable to control the length of the waste reel 603 within n times (n≤6) the width of the waste.

In order to avoid the situation where part of the waste is wound around the waste reel 603 and the other part of the waste extends out of the waste reel 603, the reciprocating displacement of the fixed frame 602 is controlled within a range less than the axial length of the waste reel 603, thereby achieving the waste being completely wound around the outside of the waste reel 603.

Specifically, the bottom of the fixed frame 602 is connected to the linear sliding drive assembly 610 located on the base 601, and the linear sliding drive assembly 610 drives the fixed frame 602 to slide along the axial direction of the waste winding shaft 603. The linear sliding drive assembly 610 can adopt a structural assembly with a linear sliding movement function in the prior art. Specifically, the linear sliding drive assembly 610 is a structure in which a screw nut driving member, a linear slide rail and a slide seat cooperate.

Specifically, a material stringing rack 606 is provided beside the fixed frame 602. In actual application, the waste material winding module 6 is located at one side of the frame 1, and the material stringing rack 606 is located between the waste material winding module 6 and the frame 1, and is used to guide the multiple waste materials generated during the die-cutting operation of the equipment. The material stringing rack 606 includes an outer frame 607, and multiple rotating shafts 608 are rotatably installed inside the outer frame 607 from top to bottom. The axial direction of the rotating shaft 608 is consistent with the axial direction of the waste material winding shaft 603, and the rotating shaft 608 guides the waste to the corresponding waste material winding shaft 603 for winding. In order to avoid mutual interference in the process of conveying the multiple waste materials generated during the die-cutting operation to the corresponding waste material winding shaft 603, the waste can be limited by the inner side of the outer frame 607, and the waste generated by the corresponding die-cutting station is directed to the corresponding waste winding shaft 603 for winding operation through the rotating shaft 608 in the outer frame 607, so as to avoid cross interference between the waste materials.

Specifically, the number and position of the rotating shaft 608 correspond to the number and position of the waste reel 603. The number of waste reel modules 6 and the number of waste reel shafts 603 installed in each waste reel module 6 are arranged based on the number of die-cutting stations in the die-cutting module 5. Usually, the waste reel module 6 is arranged on one side of the frame 1, and the finished product automatic reel module 7 is arranged on the other side of the frame 1. Then, the number and position of the rotating shaft 608 are reasonably arranged according to the number and position of the waste reel shaft 603.

Specifically, the rotating shaft 608 is installed at the same height as the corresponding waste reel 603, or slightly lower than the corresponding waste reel 603, or slightly higher than the corresponding waste reel 603. In order to shorten the conveying path of the waste as much as possible and avoid the contact between the wastes and interference between them, the installation position of the rotating shaft 608 is reasonably set. Preferably, the rotating shaft 608 is installed at a position slightly lower than the corresponding waste reel 603, which can further reduce the height of the material stringing rack 606.

Specifically, the outer frame 607 of the material stringing rack 606 is fixedly mounted on the base 601, and a reinforcing member 609 is connected between the outer frame 607 and the base 601. The material stringing rack 606 is fixedly mounted on the base 601, and the reinforcing member 609 ensures the stable installation of the material stringing rack 606.

Specifically, a guide shaft 605 is provided beside the waste reel 603 located on the side away from the material stringing rack 606, and the guide shaft 605 is installed on the front of the fixed frame 602. In order to further increase the diameter of the waste reeled on each waste reel 603 and avoid the waste being transported from contacting and interfering with the waste roll outside the adjacent waste reel 603, a guide shaft 605 is provided beside the waste reel 603 (i.e., the waste reel 603 located on the side away from the material stringing rack 606) where interference is likely to occur, so as to further guide the conveying path of the waste, avoid the waste being transported from contacting and interfering with the waste roll outside the adjacent waste reel 603, and ensure that each waste reel 603 can reel waste with a larger diameter.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
