All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The application provides a pressing mechanism, including conveyer, base unit, briquetting and first driving element. The conveyor is used for conveying objects; the base unit comprises a supporting plane, and the supporting plane corresponds to the output end of the conveyor so as to receive objects; the pressing block is movably connected to the base unit in the direction perpendicular to the supporting plane and is positioned right above the supporting plane; the first driving element is used for driving the pressing block to move towards the supporting surface when the object is located at a preset position so as to apply pressure to the object.

The application also provides packaging box production equipment, which comprises the pressing mechanism.

The pressing mechanism and the packing box production equipment of the present application will be described in detail with reference to specific embodiments. In the following embodiments, the articles conveyed by the conveyor are boxes. In other embodiments, the articles conveyed by the conveyor may be other products, such as flat cardboard.

Embodiment one:

referring to fig. 1 and 2, fig. 1 and 2 are schematic views of three-dimensional structures of different angles of an embodiment of a packaging box production apparatus according to the present application.

As shown in fig. 1 and 2, the package production apparatus 1000 includes a conveyor 200, a detection assembly 300, a guide assembly 400, a material blocking assembly 500, a feeding mechanism 100, and a pressing mechanism 600.

The conveyor 200 is used for sequentially conveying a plurality of boxes 20, and an adhesive, such as glue, is pre-coated on the bottom of each box 20.

The detecting assembly 300 is disposed at an input end of the conveyor 200, and is used for detecting whether the quality of each box 20 is qualified, for example, whether the adhesive is uniform, and only making the qualified box 20 be transferred to a next process along with the conveyor 200.

The guide assembly 400 is fixedly arranged above the conveyor 200 and is positioned downstream of the detection assembly 300, and is used for forming a first conveying channel so as to limit a conveying path of the qualified box body 20.

The blocking component 500 is disposed corresponding to the guiding component 400, and is used for blocking the box 20 when the box 20 is conveyed to a first predetermined position in the first conveying channel of the guiding component 400.

The feeding mechanism 100 is disposed corresponding to the guide assembly 400, and is used for placing the liner 10 on the bottom surface of the box 20 after the box 20 is stopped. The lining member 10 has a flat plate shape and matches the shape of the bottom surface of the case 20.

The pressing mechanism 600 is disposed corresponding to the output end of the conveyor 200, and is used for pressing the liner 10 against the bottom surface of the box 20, so that the liner 10 is adhered to the bottom surface of the box 20.

Referring to fig. 3, fig. 3 is an enlarged view of a partial view a in fig. 2.

As shown in fig. 3, the detection assembly 300 includes a fixed bracket 310, a visual detector 320, a dial 330, a cylinder 340, and a guide member 350.

A stationary bracket 310 is fixedly disposed above the conveyor 200 and serves as a structural support for the remaining components of the detection assembly 300. The visual detector 320 is fixedly disposed on the fixing bracket 310, and is used for detecting whether the quality of the box 20 is qualified. The vision detector 320 may employ CCD image detection, as is known in the art. The dial 330 is coupled to the fixed bracket 310 by a guide member 350. The guide member 350 may guide the reciprocating movement of the shift block 330 in a direction, which in this embodiment guides the movement of the shift block 330 perpendicular to the conveying direction. The guide element 350 may be a guide post and guide sleeve structure.

When the vision detector 320 detects that the quality of the cartridge 20 is defective, the air cylinder 340 drives the dial 330 to move, thereby shifting the defective cartridge 20 to move in a direction perpendicular to the conveying direction, preventing it from entering the conveying path of the guide assembly 400.

As shown in fig. 1 and 2, the first transfer path of the guide assembly 400 extends in the transfer direction, and the transfer paths are fixed at intervals perpendicular to the transfer direction, so that the cartridge 20 can be positioned perpendicular to the transfer direction. After the blocking assembly 500 blocks the box 20, the position of the box 20 is fixed, which is beneficial to the feeding of the subsequent feeding mechanism 100.

The material blocking assembly 500 includes a first material blocking element 510, a second material blocking element 520, and a third material blocking element 530 sequentially arranged at intervals in a conveying direction.

The first blocking member 510 is a jaw cylinder to clamp both sides of the cartridge 20 perpendicular to the conveying direction. The second blocking member 520 and the third blocking member 530 are blocking cylinders to block the cartridge 20 in the conveying direction.

Referring to fig. 4 to 6, fig. 4 is a schematic three-dimensional structure of a pressing mechanism in an embodiment of a packaging box production apparatus of the present application, fig. 5 is an exploded view of the three-dimensional structure of the pressing mechanism in the embodiment of the packaging box production apparatus of the present application, and fig. 6 is a schematic cross-sectional view of the pressing mechanism in the embodiment of the packaging box production apparatus of the present application.

As shown in fig. 4 to 6, the pressing mechanism 600 includes a base unit 610, a pressing block 620, and a first driving member 630. The base unit 610 includes a supporting plane 6131, and the supporting plane 6131 corresponds to the output end of the conveyor 200 to receive the box 20 (the liner 10 is placed on the bottom surface of the box 20); the pressing block 620 is movably connected to the base unit 610 in a direction perpendicular to the supporting plane 6131 and is located right above the supporting plane 6131; the first driving member 630 serves to drive the pressing block 620 to move toward the support surface when the case 20 is located at the second predetermined position, so as to apply pressure to the bottom surface of the case 20.

In order to enable the cassette 20 on the conveyor 200 to be smoothly transferred onto the supporting plane 6131, in this embodiment, the supporting plane 6131 is parallel to and coplanar with the conveying surface of the conveyor 200 (i.e. the surface of the conveyor belt for carrying the cassette 20 if the conveyor 200 is a belt conveyor).

After the box 20 is conveyed out from the output end of the conveyor 200, the box 20 continues to move on the supporting plane 6131 under the pushing of the following box 20 or under the driving of a separately arranged driving device (a transmission assembly 640 below), when the box moves to a second preset position, the pressing block 620 presses the lining member 10 and the bottom surface of the box 20, and then the box 20 continues to be conveyed to the next conveyor, or the operation is completed.

A support plane 6131 is provided outside the conveyor 200, and the support plane 6131 may be provided to be rigid, so that the lining member 10 may be pressed against the bottom surface of the case 20 on the support plane 6131.

In order to enable the cassette 20 to move stably and controllably on the support surface 6131, the pressing mechanism further includes a transmission assembly 640, and the transmission assembly 640 is disposed on the base unit 610 and is used for guiding and driving the cassette 20 to move.

Specifically, the transmission assembly 640 includes two transmission units 641 disposed in mirror image, the two transmission units 641 being disposed on the base unit 610 at intervals in a first direction parallel to the support plane 6131, each transmission unit 641 including a mount 6411, an elastic member 6412, a plurality of rollers 6413, and a second driving element 6414. Mount 6411 is movably coupled to base unit 610 in a first direction that is parallel to support plane 6131; elastic member 6412 is connected between mount 6411 and base unit 610; each roller 6413 is rotatably disposed on the mount 6411 about its axis, and the plurality of rollers 6413 are arranged at intervals in a second direction, which is perpendicular to the first direction and parallel to the support plane 6131; a second driving member 6414 is provided on the mount 6411 for driving the roller 6413 to rotate.

The second direction is the conveying direction of the conveyor 200.

The plurality of rollers 6413 in the driving unit 641 are arranged in a row, and since the two driving units 641 are spaced apart, the two rows of rollers 6413 in the driving assembly 640 can form a second conveying path guiding the movement of the case 20.

Meanwhile, since the distance between the two mountings 6411 in the transmission assembly 640 in the first direction is elastically adjustable, the two rows of rollers 6413 can float, and the gap between the two rows of rollers 6413 can be adjusted to be slightly smaller than the thickness of the box 20 in the first direction, so that the two rows of rollers 6413 can be clamped on two sides of the box 20, and the rollers 6413 rotate under the driving of the second driving element 6414 and drive the box 20 to move through friction.

The transmission assembly 640 of the present embodiment simultaneously achieves the function of guiding and driving the movement of the cartridge 20.

The specific structure of mount 6411 attached to base unit 610 is as follows:

each transmission unit 641 includes a fixing 6415, a pull rod 6416, and a stopper 6417. Fixing member 6415 is fixed to base unit 610 and spaced apart from mounting member 6411 in the first direction; tie bar 6416 extends in the first direction with one end fixed to mount 6411 and the other end extending through mount 6415 and in sliding engagement with mount 6415; stopper 6417 is fixed to the other end of tie rod 6416 for abutting against mount 6415; wherein elastic member 6412 is sleeved outside tie rod 6416 and abuts between mount 6411 and mount 6415.

When cassette 20 moves between the two rows of rollers 6413, the rollers 6413 on both sides are pressed, the pressing force is transmitted to mount 6411, mount 6411 moves toward mount 6415, and dynamic balance is maintained under the elastic force of elastic member 6412, so that rollers 6413 can float.

In other embodiments, tie bar 6416 may be secured to anchor 6415 at one end and extend through mount 6411 at the other end, with retainer 6417 being configured to abut mount 6411.

To facilitate adjustment of the spring force of elastic members 6412 and thus the clamping force of the two rows of rollers 6413, stopper 6417 is screwed onto pull rod 6416, and the position of stopper 6417 on pull rod 6416 can be adjusted by screwing in or screwing out. The smaller the spacing between limiter 6417 and mount 6411, the greater the elastic force of elastic member 6412. The elastic member 6412 may be a spring.

The second driving element 6414 in the transmission unit 641 drives the roller 6413 to rotate as follows:

the second driving element 6414 is a motor, and the motor is connected to one of the rollers 6413 via a first conveyor belt 6418 to drive, and two adjacent rollers 6413 are connected to each other via a second conveyor belt 6419 to drive (all the second conveyor belts 6419 are not shown in the drawing).

Specifically, the pressing mechanism 600 further includes a stopping unit 650, where the stopping unit 650 is configured to stop the object when the object moves to a predetermined position.

The stopping unit 650 may include a cylinder and a stopper fixed to a driving end of the cylinder, and the cylinder is operated when the movement of the cartridge 20 to the second predetermined position is detected, so that the stopper is stopped on a transfer path of the cartridge 20, thereby stopping the cartridge 20, and the cylinder is operated to release the cartridge 20 after the pressing down of the pressing block 620 is completed.

Specifically, the base unit 610 includes a frame 611, a boss 612, and a support block 613. The frame 611 includes a mounting plane 61111; the bump 612 is convexly arranged on the mounting plane 61111; the supporting block 613 is located above the mounting plane 61111 and fixedly connected with the bump 612, and the supporting plane 6131 is arranged on the supporting block 613; wherein, the pressing block 620 is movably connected to the frame 611 in a direction perpendicular to the supporting plane 6131, and does not intersect with the projection of the bump 612 on the supporting plane 6131 in a direction perpendicular to the supporting plane 6131.

A portion of the supporting block 613 is suspended, and when the pressing block 620 generates pressure on the supporting block 613, the supporting block 613 generates a certain deformation, and the pressure of the pressing block 620 can be monitored by detecting the deformation of the supporting block 613, for example, the distance between the supporting block 613 and the mounting plane 61111.

The deformation is small and does not affect the press-fit lining member 10 and the case 20.

Specifically, the frame 611 includes a bottom plate 6111, a top plate 6112, a post 6113, a guide sleeve 6114, and a guide post 6115. The mounting plane 61111 is arranged on the bottom plate 6111; the top plate 6112 is arranged at a distance from the bottom plate 6111 on one side of the installation plane 61111; the support column 6113 is fixedly connected between the bottom plate 6111 and the top plate 6112; the guide sleeve 6114 is fixed on the top plate 6112; the guide post 6115 is in sliding fit with the guide sleeve 6114 in the direction perpendicular to the supporting surface 6131; wherein, briquetting 620 is fixed connection with guide pillar 6115.

In order to make the pressing block 620 apply pressure to each place of the bottom surface of the case 20 as much as possible, the sidewall clearance of the case 20 of the pressing block 620 is small, and the accuracy of the movement of the pressing block 620 is high. The motion accuracy of the pressing block 620 can be ensured by guiding the pressing block by the guide post and guide sleeve structure.

Referring to fig. 7 and 8, fig. 7 is an enlarged view of a partial view B of fig. 1, and fig. 8 is an enlarged view of a partial view C of fig. 2.

As shown in fig. 7 and 8, the loading mechanism 100 includes a first vacuum nozzle 110 and a first driver 120. The first vacuum nozzle 110 communicates with a negative pressure source (not shown) for sucking the liner 10; the first driver 120 is configured to drive the first vacuum nozzle 110 to move to a first predetermined position, so that the first vacuum nozzle 110 is located directly above the box 20; wherein, when the first vacuum nozzle 110 is located at the first predetermined position, the first end surface 111 for adsorbing can be disposed obliquely with respect to the bottom surface of the box 20 (the bottom surface of the box 20 is a horizontal plane in this embodiment), so that the lining member 10 adsorbed on the first vacuum nozzle 110 can be inclined with respect to the bottom surface of the box 20, so that the lining member 10 can fall into the box 20 in an inclined posture with respect to the bottom surface of the box 20.

The lining member 10 falls into the box body 20 in a posture inclined relative to the bottom surface of the box body 20, and air in the box body 20 can be rapidly discharged during the falling process, so that the lining member 10 smoothly falls onto the bottom surface of the box body 20.

In addition, in the embodiment, the bottom surface of the box body 20 is a horizontal plane, and when the first vacuum nozzle 110 is at the first predetermined position, the lining member 10 adsorbed on the first vacuum nozzle 110 is inclined relative to the horizontal plane, compared with the horizontal state of the lining member 10, the vertical projection area is smaller, which is more beneficial to aligning the cavity of the box body 20. Specifically, the first vacuum nozzle 110 is fixedly disposed at the driving end of the first driver 120, and the first end surface 111 is always inclined relative to the bottom surface of the box 20.

Because the inner wall of the liner 10 and the box 20 has a small gap, the positional accuracy of the guide assembly 400 and/or the first vacuum nozzle 110 is ensured. In this embodiment, the first vacuum nozzle 110 is fixedly arranged, so that the position accuracy of the first vacuum nozzle is more easily ensured than that of the movable connection (second embodiment).

Specifically, the first vacuum nozzle 110 is fixedly disposed at the driving end of the first driver 120 through the connection unit 130. The connection unit 130 includes a mounting plate 131 and a connection block 132. The first vacuum nozzle 110 is fixed on the mounting plate 131; the connecting block 132 is respectively engaged with the mounting plate 131 and the driving end of the first driver 120 through a first engaging surface and a second engaging surface disposed thereon, and detachably and fixedly connected at the engaging position, and a first inclination angle of the first engaging surface relative to the second engaging surface is matched with a second inclination angle of the first end surface relative to the bottom surface of the box body 20.

A plurality of connection blocks 132 of different specifications may be provided as spare parts, and the first inclination angle of the first bonding surface and the second bonding surface of each connection block 132 is different. The second inclination angle of the first end surface 111 of the first vacuum nozzle 110 with respect to the bottom surface of the case 20 is adjusted by replacing the connection block 132.

In addition, in the present embodiment, a plurality of first vacuum nozzles 110 are provided, and each of the plurality of first vacuum nozzles 110 is fixed to the mounting plate 131. The second inclination angle of the first end surface 111 of the plurality of first vacuum nozzles 110 with respect to the bottom surface of the cartridge 20 can be adjusted in batch by replacing the connection block 132.

Further, the feeding mechanism 100 further includes a storage unit 140, a temporary storage unit 150, and a second vacuum nozzle 160.

The storage unit 140 is used for storing a plurality of lining members 10; the temporary storage unit 150 is disposed between the first predetermined position and the storage unit 140, and has a bearing surface 1541a for bearing the liner 10; the second vacuum nozzle 160 is communicated with a negative pressure source and is used for sucking the lining member 10; the first driver 120 has a first driving end (a second movable block 1222) and a second driving end (a third movable block 1232), the first vacuum nozzle 110 is fixedly arranged on the first driving end, the second vacuum nozzle 160 is fixedly arranged on the second driving end, the first driver 120 is used for driving the second vacuum nozzle 160 to reciprocate between the storage unit 140 and the temporary storage unit 150 so as to convey the lining member 10 from the storage unit 140 to the bearing surface 1541a, and driving the first vacuum nozzle 110 to reciprocate between the temporary storage unit 150 and the first predetermined position so as to convey the lining member 10 on the bearing surface 1541a to the first predetermined position.

A plurality of lining members 10 are vertically stacked in the storage unit 140, and when the top lining member 10 is removed, the remaining lining members 10 are lifted, so that the top lining member 10 is at the same height. The storage unit 140 is a prior art, and will not be described herein.

And (3) feeding:

the second driving end drives the second vacuum suction nozzle 160 to move to the storage unit 140 to suck the lining piece 10, and meanwhile, the first driving end drives the first vacuum suction nozzle 110 to move to the temporary storage unit 150 to suck the lining piece 10;

the second driving end drives the second vacuum nozzle 160 to move to the temporary storage unit 150 and drop the sucked lining member 10 on the bearing surface 1541a, and at the same time, the first driving end drives the first vacuum nozzle 110 to move right above the box 20 and drop the sucked lining member 10 in the box 20.

The lining member 10 is conveyed to the temporary storage unit 150 from the storage unit 140 in a relay manner, and is conveyed to the position right above the box body 20 from the temporary storage unit 150, so that the movement path of the first vacuum suction nozzle 110 in one-time feeding process is shortened, and the feeding speed is improved.

In this embodiment, the first vacuum nozzle 110 and the second vacuum nozzle 160 are driven by the first driver 120 at the same time, and in other embodiments, a sixth driver may be provided to drive the second vacuum nozzle 160. Specifically, the loading mechanism 100 further includes a sixth driver (not shown) for driving the second vacuum nozzle 160 to reciprocate between the storage unit 140 and the temporary storage unit 150 to transfer the liner 10 from the storage unit 140 to the carrying surface 1541a, and the first driver 120 is for driving the first vacuum nozzle 110 to reciprocate between the temporary storage unit 150 and the predetermined position to transfer the liner 10 on the carrying surface 1541a to the predetermined position.

Specifically, the second end surface 161 for suction of the second vacuum nozzle 160 is parallel to the bottom surface of the case 20; the bearing surface 1541a is switchable between parallel with respect to the bottom surface of the case 20 and inclined with respect to the bottom surface of the case 20.

When the second vacuum nozzle 160 drops the sucked liner 10 onto the bearing surface 1541a, the bearing surface 1541a is controlled to be in a parallel state with respect to the bottom surface of the casing 20. When the first vacuum nozzle 110 sucks the liner 10 at the temporary storage unit 150, the bearing surface 1541a is controlled to be inclined with respect to the bottom surface of the box 20. Thereby ensuring that the second vacuum nozzle 160 can accurately drop the liner 10 and the first vacuum nozzle 110 can accurately suck the liner 10.

The second end surface 161 is parallel to the bottom surface of the case 20 in the above structure, and the corresponding storage unit 140 is also of a conventional structure, so that the manufacturing and the installation are convenient.

To achieve that the carrying surface 1541a can be switched between a state parallel to the bottom surface of the case 20 and a state inclined to the bottom surface of the case 20, the stock unit 150 includes a first mounting member 151, a second mounting member 152, a second driver 153, a third mounting member 154, and a third driver 155. The second mounting element 152 is rotatably connected to the first mounting element 151 about a first reference axis; the second driver 153 is used for driving the second mounting element 152 to rotate; the third mounting member 154 is rotatably coupled to the second mounting member 152 about a second reference axis; the third driver 155 is used for driving the third mounting element 154 to rotate; wherein the bearing surface 1541a is disposed on the third mounting member 154.

The second driver 153 and the third driver 155 may be cylinders.

By the above structure, the bearing surface 1541a (the third mounting member 154) can be made rotatable about the first reference axis and/or the second reference axis, thereby adjusting the orientation of the bearing surface 1541a.

Specifically, the second reference axis is perpendicular to the first reference axis and is parallel to the bottom surface of the case 20. The orientation of the third mounting element 154 may be widely adjusted.

Further, in order to prevent the liner 10 from falling off when the bearing surface 1541a is inclined relative to the bottom surface of the box 20, the temporary storage unit 150 is provided with a bearing groove 1541, and the bottom surface of the bearing groove 1541 forms the bearing surface 1541a. The liner 10 is restrained by the side walls of the bearing recess 1541.

Specifically, the first driver 120 includes a first cylinder 1211, a first movable block 1212, a second cylinder 1221, a second movable block 1222, a third cylinder 1231, and a third movable block 1232. The first movable block 1212 is capable of reciprocating in a first direction (transverse direction) relative to the first cylinder 1211, the first direction being a first predetermined position and a connecting direction of the storage unit 140; the second cylinder 1221 is fixed on the first movable block 1212; the second movable block 1222 is reciprocally movable in a second direction (vertical) with respect to the second cylinder 1221, the second direction being perpendicular to the first direction, the second movable block 1222 being a first driving end; the third cylinder 1231 is fixed on the first movable block 1212; the third movable block 1232 can reciprocate in the second direction relative to the third cylinder 1231, and the third movable block 1232 is the second driving end.

The first cylinder 1211 and the first movable block 1212 may form a motor screw nut pair, the second cylinder 1221 and the second movable block 1222 may form a cylinder, and the third cylinder 1231 and the third movable block 1232 may form a cylinder.

In the first direction, the first vacuum nozzle 110 and the second vacuum nozzle 160 are simultaneously driven to move through the first cylinder 1211 and the first movable block 1212, so that the consistency of the motion is ensured, the control is convenient, and the structure of the first driver 120 is simplified.

The fourth driver 173 and the fifth driver 175 may be cylinders.

By the above structure, the first end surface 111 (the first vacuum nozzle 110) can be rotated about the third reference axis and/or the fourth reference axis, thereby adjusting the orientation of the first end surface 111.

Specifically, the fourth reference axis is perpendicular to the third reference axis and is parallel to the bottom surface of the case 20. The orientation of the third connecting element 174 can be adjusted over a wide range.

Further, the feeding mechanism 100 further includes a storage unit 140, a temporary storage unit 180, and a second vacuum nozzle 160.

The storage unit 140 is used for storing a plurality of lining members 10; the temporary storage unit 180 is disposed between the first predetermined position and the storage unit 140, and is provided with a bearing surface 181 for bearing the liner 10, where the bearing surface 181 is parallel to the bottom surface of the box 20; the second vacuum nozzle 160 communicates with a negative pressure source (not shown) for sucking the liner 10; the first driver 120 has a first driving end and a second driving end, the first vacuum nozzle 110 is connected to the first driving end through the connection unit 170, the second vacuum nozzle 160 is fixedly arranged at the second driving end, the second end surface 161 of the second vacuum nozzle 160 for adsorbing is parallel to the bottom surface of the box body 20, the first driver 120 is used for driving the second vacuum nozzle 160 to reciprocate between the storage unit 140 and the temporary storage unit 180 so as to convey the lining member 10 from the storage unit 140 to the bearing surface 181, and driving the first vacuum nozzle 110 to reciprocate between the temporary storage unit 180 and the first predetermined position so as to convey the lining member 10 on the bearing surface 181 to the first predetermined position.

The temporary storage unit 180 in this embodiment is different from the temporary storage unit 150 in the first embodiment, and the temporary storage unit 180 in this embodiment has a simple structure.

And (3) feeding:

the second driving end drives the second vacuum suction nozzle 160 to move to the position of the material storage unit 140 to suck the lining piece 10, and meanwhile, the first driving end drives the first vacuum suction nozzle 110 to move to the position of the temporary storage unit 180 to suck the lining piece 10;
