Referring to fig. 1, fig. 1 is a schematic structural diagram of a transmission structure according to an embodiment of the present disclosure. The embodiment of the application provides a conveying structure, and when this conveying structure can be used to the encapsulation packing box, to the automatic transmission process of packing box, also can be applicable to other processes that need to treat that the piece carries out automatic conveying. The following description will be given taking the structure of the package case as an example.

The conveying structure comprises a rotary table 3, a first conveying mechanism 1 and a second conveying mechanism 2; the first conveying mechanism 1 is in driving connection with the first driving mechanism, the rotary table 3 is in driving connection with the second driving mechanism, and the second conveying mechanism 2 and the first conveying mechanism 1 are sequentially arranged along the conveying direction of the piece to be processed; the first conveying mechanism 1 is fixedly arranged on the upper side of the rotary table 3, a first monitoring device 19 is arranged on the side of the rotary table 3, and the first monitoring device 19 is used for acquiring the rotating state of the rotary table 3; the second conveying mechanism 2 is in driving connection with the third driving mechanism, a second monitoring device 20 is arranged on the side of the second conveying mechanism 2, and the second monitoring device 20 is used for acquiring the conveying state of the to-be-treated piece on the second conveying mechanism 2; the first driving mechanism, the second driving mechanism, the third driving mechanism, the first monitoring device 19 and the second monitoring device 20 are respectively electrically connected with a controller, and the controller is used for controlling the second conveying mechanism to convey the to-be-treated piece to the first conveying mechanism according to the rotating state of the turntable and the conveying state of the to-be-treated piece on the second conveying mechanism.

The first conveying mechanism 1 and the second conveying mechanism 2 can be conventional conveying structures at present, can be belt conveying, can also be roller conveying lines, or other conveying structures as long as the requirements for automatically and continuously conveying the pieces to be processed can be met. Hereinafter, unless otherwise specified, a structure in which the transfer mechanism is a roller line will be described as an example.

The second conveying mechanism 2 and the first conveying mechanism 1 are arranged in sequence in the flow direction of the pieces to be treated, so that the pieces to be treated on the second conveying mechanism 2 can be conveyed directly onto the first conveying mechanism 1. The conveying directions of the first conveying mechanism and the second conveying mechanism can be the same or different, and the packing boxes on the second conveying mechanism 2 can conveniently and smoothly enter the first conveying mechanism 1. The first driving mechanism and the third driving mechanism may be conventional driving structures, as long as the driving structure can drive the corresponding conveying structure to normally move. And the first driving mechanism and the third driving mechanism are respectively connected with the controller, so that the first conveying mechanism 1 and the second conveying mechanism 2 are convenient to be controlled in a linkage manner.

The second driving mechanism is in driving connection with the turntable 3 for driving the turntable to rotate, and the structure of the driving connection between the second driving mechanism and the turntable is not particularly limited. The turntable is generally horizontally disposed, and as a specific implementation, for example, the second driving mechanism and the turntable 3 may be in driving connection through a turntable transmission assembly. The carousel drive assembly may include a drive gear and a driven gear. The rotary table 3 can be fixedly sleeved on a rotary table rotating shaft, and the bottom end of the rotary table can be rotatably arranged on a base through structures such as a bearing and the like. The rotating shaft of the turntable is vertically arranged, and the rotating shaft of the turntable is fixedly sleeved with the driven gear; a driving gear is fixedly sleeved on a driving shaft of the second driving mechanism or a transmission shaft connected with the driving shaft; the driving gear is directly meshed with the driven gear; alternatively, the turntable drive assembly may further comprise an intermediate transmission member, the driving gear and the driven gear being indirectly connected via the intermediate transmission member.

When the driving gear rotates, the driving gear drives the driven gear to rotate, so as to drive the rotary table 3 to rotate. The second driving mechanism is electrically connected with the controller, so that the operation states of the rotary disc 3 and the conveying mechanism can be controlled conveniently according to the conveying or other states of the packing box, the conveying efficiency is enhanced, and the conveying error is reduced. Moreover, by adopting the structure, the controller can conveniently acquire the rotating state of the turntable 3 according to the rotating speed of the second driving mechanism and the transmission ratio of the turntable transmission assembly. The number of turns of the rotary disc 3 which rotates for one turn, two turns or two and half turns can be conveniently obtained through the mode; when the number of turns of the rotary disc 3 reaches a preset value, the adhesive tape is wound around the packing box for one turn, two turns or two and a half turns correspondingly.

The first monitoring device 19 is provided on the side of the turntable 3, and the position thereof may not be particularly limited as long as it is convenient to acquire the rotation state of the turntable 3. For example, the first monitoring device 19 may be fixedly disposed at the tail end of the first transmission mechanism 1, and may be fixed at the lower portion of the bracket of the first transmission mechanism; or on a base on the underside of the turntable 3. The outer side of the rotary table 3 or the position close to the periphery can be correspondingly provided with a sensing position, and the height of the probe or the monitoring unit is consistent with that of the sensing position on the rotary table 3.

The first monitoring device 19 is electrically connected to the controller, so as to determine the packaging completion state of the packaging box according to the rotation state of the turntable 3. For example, when the rotary disc 3 rotates one turn, the adhesive tape winds one turn around the side of the packing box, and then the packaging is completed; or, the rotary disc 3 rotates for two circles, and the adhesive tape is wound for two circles around the side part of the packing box, so that the packaging is considered to be finished. Specifically, the relation between the completion state of the packaging box packaging and the number of rotation turns of the turntable can be specifically set according to actual requirements. The first monitoring device 19 may be a rotation reset sensor or other monitoring device capable of acquiring the rotation state of the turntable 3.

Specifically, the first monitoring device includes a first signal transmitting element 19a and a first signal receiving element 19 b; the first signal transmitting element 19a and the first signal receiving element 19b are electrically connected to the controller, respectively, or alternatively, the first signal transmitting element 19a or the first signal receiving element 19b may be electrically connected to the controller according to the type of the monitoring device. The first signal emitting element 19a of the first monitoring device is fixedly arranged on the fixed seat at the lower side of the turntable or on the bracket of the second conveying mechanism, the first signal receiving element 19b of the first monitoring device is fixedly arranged on the turntable 3 and is preferably arranged at a position on the turntable 3 close to the periphery of the turntable 3, and the first signal emitting element 19a and the first signal receiving element 19b are the same in height, so that the transmission of signals is facilitated. By adopting the structure, the first monitoring device can conveniently and accurately acquire the rotation state of the turntable 3. The rotating state of the turntable 3 can be accurately acquired through the rotating speed of the second driving mechanism and the transmission ratio of the transmission assembly or through the first monitoring device; or, through the combination of the two modes, the rotating state of the turntable 3 can be more accurately acquired by monitoring the rotating state of the turntable 3, so that the packaging box packaging process can be more accurately controlled.

The second monitoring device is disposed on the side of the second conveying mechanism 2. The second monitoring device includes a second signal transmitting element 20a and a second signal receiving element 20 b; the second signal transmitting element 20a and the second signal receiving element 20b are electrically connected to the controller, respectively, or alternatively, the second signal transmitting element 20a or the second signal receiving element 20b may be electrically connected to the controller according to the type of the monitoring device. Usually the second monitoring device is placed at the tail end of the second transport mechanism 2 and the second signal emitting element 20a and the second signal receiving element 20b are located at the upper side of the second transport mechanism 2. The second signal transmitting element 20a and the second signal receiving element 20b are arranged on both sides of the second transmission mechanism 2 in the width direction of the second transmission mechanism 2.

When the packing box on the second conveying mechanism 2 is conveyed to the tail end of the second conveying mechanism 2, the second monitoring device can sense that the packing box is arranged at the position, so that the conveying state of the second conveying mechanism 2 to the first conveying mechanism 1 can be controlled more accurately. The second monitoring device and a third driving mechanism for driving the second conveying mechanism 2 to operate are respectively electrically connected with the controller. The second monitoring device may be a photoelectric sensor or other monitoring devices capable of acquiring whether the to-be-processed piece reaches the corresponding position.

When having the packing box when encapsulating on first transport mechanism 1, the controller can control 2 stop motion of second transport mechanism, can avoid the packing box on the second transport mechanism 2 still at rotatory in-process by continuing to convey on first transport mechanism 1 at carousel 3, can enough ensure that the packing box is conveyed to first transport mechanism 1 smoothly on, avoid the packing box to drop, can avoid having a plurality of packing boxes simultaneously on the first transport mechanism 1 again and influence the normal clear of packing box encapsulation, can also avoid a plurality of packing boxes to appear the extrusion and cause the condition of packing box damage at rotatory in-process.

The first driving mechanism, the second driving mechanism, the third driving mechanism, the first monitoring device and the second monitoring device are electrically connected with the controller respectively. The first monitoring device and the second monitoring device acquire information and transmit the information to the controller, and the controller controls the start-stop state of the first driving mechanism, the second driving mechanism and/or the third driving mechanism according to the information of the monitoring devices. The controller can also be electrically connected with a control mechanism of the adhesive tape machine so as to control the action of the adhesive tape machine in a linkage manner. The sealing-tape machine can be fixed in carousel 3 sides, and the pivot of rolling up the sticky tape on the sealing-tape machine can follow vertical direction and set up, and the sticky tape can compress tightly in packing box side.

By adopting the structure, the packaging box can be conveniently packaged in the first conveying mechanism 1 according to the packaging completion state and the information whether the packaging box is arranged at the tail end of the second conveying mechanism, so that the state that the second conveying mechanism 2 conveys the packaging box to the first conveying mechanism 1 can be controlled. When the first conveying mechanism 1 does not have a packing box and the second monitoring device senses that the packing box is arranged at the tail end of the second conveying mechanism 2, the controller controls the first conveying mechanism 1 and the second conveying mechanism 2 to start, and the packing box on the second conveying mechanism 2 is conveyed to the first conveying mechanism 1; meanwhile, the packing boxes on the second conveying mechanism 2 are continuously conveyed to the tail part of the second conveying mechanism, and when the packing boxes are conveyed to the tail part of the second conveying mechanism 2, corresponding operation is executed according to the packaging state of the packing boxes on the first conveying mechanism 1. After the packing box is conveyed to the first conveying mechanism 1, the packing box continues to move to a preset position along the conveying direction; after the packing box reaches the predetermined position, first conveying mechanism 1 stops moving.

The adhesive tape of the adhesive tape machine is tightly pressed on the side of the packing box and is positioned at the position to be packaged of the packing box. Then, the controller controls the second driving mechanism to start to drive the rotary disc 3 to rotate, the first conveying mechanism 1 and the packaging box on the upper side of the first conveying mechanism rotate along with the rotary disc 3, and the adhesive tape is continuously pulled out from a rotary shaft for winding the adhesive tape, so that the adhesive tape can be attached to the packaging box from the side of the packaging box; under this state, the number of turns of the adhesive tape wound on the packing box is consistent with the number of turns of the packing box, and control conditions can be specifically set according to packaging requirements. And after the packaging box is packaged, the controller controls the rotary disc 3 to stop rotating according to the information acquired by the first monitoring device, the first conveying mechanism 1 is started, and the packaged packaging box on the first conveying mechanism 1 is conveyed to the next procedure continuously. At the same time, the containers on the second transfer mechanism 2 that have been transferred to the tail end thereof are transferred to the first transfer mechanism 1.

When the second monitoring device 20 senses that the packaging box on the second conveying mechanism 2 has been conveyed to the tail end of the second conveying mechanism 2, the controller controls the second conveying mechanism 2 to stop moving, and the packaging box on the second conveying mechanism 2 is not conveyed to the first conveying mechanism 1. And, after the packing box encapsulation on first transport mechanism 1 is accomplished, when the tail end department of second transport mechanism 2 does not have the packing box, first transport mechanism 1 can stop the action, after having the packing box at second transport mechanism 2 tail end department, begins to continue the action again.

By adopting the structure, the transmission efficiency of the transmission structure can be greatly improved, and the failure rate in the transmission process is reduced. Moreover, the situation that a plurality of packing boxes are arranged on the first conveying mechanism 1 at the same time to influence the packaging efficiency and the packing boxes are extruded to cause damage to the packing boxes can be avoided. Meanwhile, in the process that the packaging box is packaged, the rotary table 3, the conveying mechanisms and the adhesive tape machine can improve the operation efficiency, effectively reduce the idle rotation rate, reduce the energy consumption and prolong the service life.

On the basis of the above embodiment, the present embodiment provides a conveying structure, which further includes two clamping assemblies; the two clamping assemblies are arranged along the width direction of the first conveying mechanism, the length direction of the clamping part of any clamping assembly is parallel to the conveying direction of the first conveying mechanism 1, and any clamping part is arranged on the upper side of the first conveying mechanism 1; one of the clamping assemblies can move towards or away from the other clamping assembly, or the two clamping assemblies can move towards or away from each other.

Since the conveying surface of the conveying mechanism is generally along a horizontal plane, the present application will be described by taking a structure in which the conveying mechanism is horizontally disposed and the conveying surface thereof is along the horizontal plane as an example, unless otherwise specified. For any clamping assembly, it includes a support portion and a clamping portion. The upper end part of the supporting part is fixedly connected with the clamping part; taking the structure of the roller conveyor line as an example, the lower end of the support portion may extend directly downward, passing through the first conveyor 1, so that the support portion is located between any two adjacent rollers. Typically, the support portions of the two gripper assemblies are arranged in the width direction of the first conveying mechanism. Wherein, for any clamping component, the supporting part can be one or a plurality of supporting parts; hereinafter, the structure of one support portion will be described as an example unless otherwise specified.

The structure of the clamping portion may not be particularly limited as long as it has a structure that is convenient to be attached to one side of the packing box and tightly pressed against the side of the packing box. Generally, the clamping part is of a strip-shaped, rod-shaped or other structure; it can be solid or hollow structure, and also can be in the shape of ']' and the like, so long as the clamping and the installation are convenient.

The length direction of the clamping part is along the conveying direction of the first conveying mechanism 1, and the length and the width along the vertical direction of the clamping part can be specifically set according to actual requirements; generally, the width of the packing box is not easy to be too large so as to avoid influencing the packaging position of the packing box.

For any clamping assembly, the clamping part is positioned at the upper side of the first conveying mechanism 1. The clamping parts of the two clamping components are positioned at the same height. When one clamping component approaches to the other clamping component or the two clamping components approach to each other, the two clamping parts can clamp the packing box between the two clamping parts. By adopting the structure, the position of the packaging box reaching the preset position on the first conveying mechanism 1 can not change any more in the packaging box packaging process, and the packaging process is more stable. When only one clamping assembly moves along the width direction of the first conveying mechanism, a driving mechanism is correspondingly arranged; when the two clamping assemblies can be close to or far away from each other, the two driving mechanisms can be correspondingly arranged to respectively drive the corresponding clamping assemblies to move, so that the purpose of closing to or far away from each other is achieved.

On the basis of the above embodiments, the present embodiment provides a conveying structure, which further includes a transmission mechanism; the clamping assembly further comprises a supporting portion, the upper end portion of the supporting portion is fixedly connected with the clamping portion, and the transmission mechanism is in transmission connection with the supporting portions of the two clamping assemblies respectively.

The transmission mechanism is used for driving one clamping assembly to approach or depart from the other clamping assembly, or driving the two clamping assemblies to approach or depart from each other. As a more preferable mode, a transmission mechanism is adopted and is respectively in transmission connection with the supporting parts of the two clamping components so as to drive the two clamping components to approach or separate from each other, the action efficiency is higher, the position of the packing box is convenient to position, and the position of the packing box is more convenient to position on the central line of the first transmission mechanism 1 so as to position the packing box at the central position of the turntable 3; meanwhile, the structure is more compact, and the phenomenon that the action and the clamping stability are influenced due to the overlarge stroke of a single clamping assembly when the single clamping assembly acts is avoided.

The structure of the support portion may not be specifically limited, and the holding portion may be moved along the width direction of the first conveying mechanism 1 on the upper side of the first conveying mechanism 1 as long as the holding portion is conveniently supported. In particular, the support is typically a rod-like structure. In order to make the clamping assembly more stable in the moving process, the supporting part can be further provided with a first sliding block or other supporting structures, and the first sliding block can be arranged into a structure which is in sliding fit with the upper side surface of the rotary table 3 or other fixing structures fixed on the upper side of the rotary table 3.

Also, as one of specific implementations, when the first conveying mechanism 1 is a conveyor belt or other structure that does not facilitate the support portion to pass through the conveyor belt directly, the support portion may further include a U-shaped link and a strut. One end of the U-shaped connecting rod is fixedly connected with the side part of the clamping part, and the other end of the U-shaped connecting rod is fixedly connected with the upper end part of the supporting rod. When the supporting part is also provided with a first sliding block, the lower end part of the supporting rod is fixedly connected with the top part of the first sliding block.

One end of the U-shaped link is located on the upper side of the conveying surface of the first conveying mechanism 1, the other end of the U-shaped link is located on the lower side of the conveying surface of the first conveying mechanism 1, and the U-shaped link can be penetrated through a side arm of the first conveying mechanism 1 or other hollow positions on the bracket of the first conveying mechanism 1. By adopting the structure, the structure of the clamping assembly does not influence the normal operation of the conveying mechanism, and the function of driving the clamping part to move along the width direction of the first conveying mechanism 1 can be realized.

Moreover, for any clamping assembly, a plurality of supporting parts can be arranged; usually two are provided. The structure of the two support portions will be described as an example. The two support portions are arranged in the length direction of the nip portion thereof, that is, in the conveying direction of the first conveying mechanism 1. The two support parts can be fixedly connected through a support part connecting piece 17.

The first conveying mechanism 1 is of a conventional structure, and may include a support, the upper side of the support is usually provided with two side arms, the length direction of any side arm is parallel to the conveying direction, and the conveyor belt or the roller is rotatably mounted between the two side arms. The first drive wheel 15 and the second drive wheel 16 may be gears, sprockets, pulleys or other wheel-like structures; the first conveyor belt and the second conveyor belt can be belt transmission, chain transmission or other transmission structures.

For convenience of description, the two clamping components are a first clamping component and a second clamping component respectively; the first clamping assembly comprises a first clamping portion 4 and a first support portion 6, and the second clamping assembly comprises a second clamping portion 5 and a second support portion 7. The two side arms are a first side arm 10 and a second side arm 11 respectively.

In addition, in order to facilitate the transmission connection of the transmission belt, the heights of the two bulges on the first supporting part 6 of the first clamping component are different from the heights of the two bulges on the second supporting part 7 of the second clamping component, and the difference of the heights is the diameter of the transmission wheel, or is slightly larger than or slightly smaller than the diameter. The structure of the protrusion is not particularly limited, and may be any structure that facilitates the fixing of the driving belt.

The fixing portion of the linear transmission member 12 can be fixed on the bracket, the side arm or other fixing structure of the first transmission mechanism 1, one end portion of the transmission shaft of the linear transmission member 12 is in sliding fit with the fixing portion of the linear transmission member 12, the other end portion of the transmission shaft is fixedly connected with the first supporting portion 6 of the first clamping component or the second supporting portion 7 of the second clamping component, and the extension direction of the transmission shaft is parallel to the width direction of the first transmission mechanism 1.

The linear transmission member 12 may be driven by a driving mechanism such as a motor, or an electric cylinder with a servo motor and an air cylinder integrated therewith to realize the functions of the driving mechanism and the linear transmission member 12.

The structure of the linear actuator 12 in driving connection with the first supporting portion 6 of the first clamping assembly will be described as an example. The linear transmission part 12 drives the first supporting part 6 of the first clamping component to move towards the direction far away from the second clamping component, and the first supporting part 6 drives the first end part of the second transmission belt 14 to move towards the direction far away from the second side arm 11, so that the second end part of the second transmission belt 14 moves towards the direction close to the second side arm 11; the second end of the second belt 14 drives the second supporting portion 7 of the second clamping assembly to move towards the direction close to the second side arm 11; the second supporting portion 7 of the second clamping assembly drives the second end portion of the first transmission belt 13 to move towards the direction close to the second side arm 11, and the second end portion of the first transmission belt 13 can also drive the first end portion of the first transmission belt 13 to move towards the direction close to the first side arm 10 while moving towards the direction close to the second side arm 11.

Because the length of the two transmission belts is unchanged, the movement of the two clamping pieces away from each other can be realized through the action process. The principle that the two clamping assemblies are far away from each other is the same, and when the linear transmission piece 12 drives the first supporting part 6 of the first clamping assembly to move towards the direction close to the second clamping assembly, the two clamping assemblies can be close to each other. By adopting the structure, the purpose of simultaneously driving the two clamping assemblies can be realized only by one transmission mechanism, the structure is simpler and more compact, and simultaneously, the actions of the two clamping assemblies are synchronous, so that the stability is better.

It can be understood that when a clamping assembly is provided with a plurality of supporting parts, a group of first driving wheel 15, second driving wheel 16, first driving belt 13 and second driving belt 14 are correspondingly arranged between a pair of corresponding supporting parts of two clamping assemblies along the width direction of the first conveying mechanism 1; that is, the number of the first driving wheel 15, the second driving wheel 16, the first driving belt 13 and the second driving belt 14 is the same as the number of the supporting parts of one clamping assembly, and the specific connection mode is the same as the structure that only one supporting part is arranged on the clamping assembly, and the description is omitted here. At this time, the transmission shaft of the linear transmission member 12 is fixedly connected with a support portion connecting member 17, so that the driving/transmission connection of the transmission assembly and the clamping assembly is realized.

As a specific implementation manner, screw holes may be formed in the supporting portions of the two clamping assemblies, for example, when the supporting portions include the first sliding block, the screw holes may be formed in the first sliding block, and an axial direction of the screw holes is the same as a width direction of the first conveying mechanism 1. The axis of the first screw is parallel to the width direction of the first conveying mechanism 1; the first screw rod sequentially passes through a screw hole on the first supporting part 6 of the first clamping assembly and a screw hole on the second supporting part 7 of the second clamping assembly and is in threaded fit with the two supporting parts; the screw thread directions of the screw holes on the two supporting parts are opposite. It can be understood that when one clamping assembly has two supporting portions, two first screw rods are correspondingly provided.

The first screw may be a bidirectional screw. The two clamping assemblies can be moved toward or away from each other when the first screw is rotated. The two ends of the first screw are rotatably connected to the two side arms of the first conveying mechanism 1, for example, one end of the first screw is connected to the first side arm 10 through a bearing, and the other end is connected to the second side arm 11 through a bearing.

Because the action that two centre gripping subassemblies are close to each other or keep away from is comparatively frequent, consequently, preferably adopt actuating mechanism such as motor drive first screw rod to rotate to control more intelligently, high-efficiently. The gear sleeved on the driving shaft of the driving mechanism can be directly or indirectly meshed with the first screw rod. The structure is simple, and the purpose of simultaneously driving the two clamping assemblies can be realized by one driving/transmission mechanism; and, two supporting parts move along the axial of first screw rod, and first screw rod can also play the effect of direction.

On the basis of the above embodiments, the present embodiment provides a conveying structure, the transmission mechanism further includes a guide rod 18, an axis of the guide rod is parallel to the width direction of the first conveying mechanism 1, the guide rod 18 sequentially passes through the supporting portions of the two clamping assemblies, and the guide rod 18 is in sliding fit with the supporting portions of the two clamping assemblies.

Specifically, one end of the guide lever 18 is fixed to the first side arm 10 of the first conveyance mechanism 1, and the other end is fixed to the second side arm 11 of the first conveyance mechanism 1. The supporting parts of the two clamping assemblies are respectively provided with a through hole, and the axis of each through hole is parallel to the width direction of the first conveying mechanism 1. The guide bar 18 is in turn passed through the through holes in the two support parts. The guide bar 18 is in sliding fit with both support portions; the support portion is able to slide along the axis of the guide bar 18 when the two clamping assemblies are moved towards or away from each other.

On the basis of the above embodiments, this embodiment provides a conveying structure, in which a third driving wheel and a fourth driving wheel are sleeved on a driving shaft of a first driving mechanism, and a synchronous connecting piece is further slidably sleeved on the driving shaft; the synchronous connecting piece is positioned between the third driving wheel and the fourth driving wheel along the axial direction of the driving shaft and is driven by the connecting piece driving component to enable the synchronous connecting piece to move along the axial direction of the driving shaft; the third driving wheel is in driving connection with the first transmission mechanism 1, and the fourth driving wheel is in driving connection with the transmission mechanism.

The third driving wheel and the fourth driving wheel are both driving wheels with combined gear rings, are respectively sleeved on the driving shaft of the first driving mechanism, and cannot rotate along with the driving shaft. The sleeving structure of the third driving wheel, the fourth driving wheel and the driving shaft is not limited in detail, and the driving shaft can be sleeved with a structure such as a bearing under normal conditions. The synchronous connecting piece can be a synchronizer, a joint sleeve and other synchronous structures; the driving shaft of the first driving mechanism is sleeved with the driving shaft, can rotate along with the rotation of the driving shaft, and can also slide along the axial direction of the driving shaft.

And, along the axial direction of the drive shaft, the synchronizing connection is located between the third drive wheel and the fourth drive wheel. The synchronizing coupling is engageable with the coupling ring gear of the third drive wheel when the synchronizing coupling slides in the axial direction of the drive shaft and approaches the third drive wheel. When the driving shaft rotates, the driving shaft drives the synchronous connecting piece to rotate along with the driving shaft, so as to drive the third driving wheel to rotate and further drive the first transmission mechanism 1.

Likewise, the synchronizing coupling can engage with the coupling ring gear of the fourth drive wheel when it slides in the axial direction of the drive shaft and approaches the fourth drive wheel. When the driving shaft rotates, the driving shaft drives the synchronous connecting piece to rotate along with the driving shaft so as to drive the fourth driving wheel to rotate, so that the driving mechanism is driven to act, and the two clamping assemblies are driven to approach or keep away from each other. With this structure, the number of driving mechanisms can be reduced, and the structure is made more compact. And, first transport mechanism 1 and two clamping components adopt same actuating mechanism drive, can increase actuating mechanism's the interval of opening and stopping, avoid actuating mechanism's frequent start-up, reduce its loss.

On the basis of the above embodiments, the present embodiment provides a conveying mechanism, in which the connecting member driving mechanism includes a connecting rod and an electromagnetic switch; the side part of the synchronous connecting piece is fixedly connected with one end part of the connecting rod, the other end part of the connecting rod is fixedly connected with the movable contact of the electromagnetic switch, and the electromagnetic switch is electrically connected with the controller. By adopting the structure, the linkage control of the synchronous connecting piece is convenient, so as to control the meshing of the synchronous connecting piece and the third driving wheel or the fourth driving wheel. Wherein the connecting rod may include a first connecting rod and a second connecting rod. The first connecting rod is vertical to a driving shaft of the first driving mechanism, and the second connecting rod is parallel to the driving shaft of the first driving mechanism; one end of the first connecting rod is fixedly connected with the side part of the synchronous connecting piece, the other end of the first connecting rod is fixedly connected with one end of the second connecting rod, and the other end of the second connecting rod is fixedly connected with the movable contact of the electromagnetic switch. By adopting the structure, the synchronous connecting piece can be driven to slide along the axis of the driving shaft of the first driving mechanism more conveniently.

On the basis of the above embodiments, the present embodiment provides a conveying structure, which further includes two limiting assemblies; the two limiting components are arranged along the width direction of the second conveying mechanism, and limiting parts 8 of the two limiting components are arranged in parallel and are positioned on the upper side of the second conveying mechanism 2; the longitudinal direction of any one of the stopper portions 8 is parallel to the conveying direction of the second conveying mechanism 2. As a more preferable implementation manner, one limiting component can move towards a direction close to or away from the other limiting component, or two limiting components can move towards or away from each other.

For any stop assembly, it includes a support member 9 and a stop portion 8. The upper end part of the supporting piece 9 is fixedly connected with the limiting part 8; taking the structure of the roller conveyor line as an example, the lower end of the supporting member 9 may extend directly downward through the second conveying mechanism 2, so that the supporting member 9 is located between any two adjacent rollers. Normally, the supports 9 of the two stop assemblies are arranged along the width direction of the second conveyor 2. Wherein, for any limiting component, the supporting component 9 can be one or a plurality of; hereinafter, the structure of one support 9 will be described as an example unless otherwise specified.

The structure of the position-limiting part 8 is not particularly limited, and usually, the position-limiting part 8 is a strip-shaped or rod-shaped structure; it may be a solid or hollow structure, or a structure with a shape like "]", as long as it is easy to install and does not affect the smooth conveyance of the packing boxes on the second conveying mechanism 2.

The length direction of the limiting part 8 is along the conveying direction of the second conveying mechanism 2, and the length and the width along the vertical direction can be specifically set according to actual requirements; generally, the width of the second conveying mechanism is not too large to avoid affecting the packaging position of the packaging box, and the length of the second conveying mechanism is equivalent to the length of the second conveying mechanism 2.

For any limiting component, the limiting part 8 is positioned at the upper side of the second conveying mechanism 2. The limiting parts 8 of the two limiting components are positioned at the same height; the area between the two limiting parts 8 forms a channel for conveying the packing boxes on the second conveying mechanism 2. Through the setting of two spacing subassemblies, make the transfer passage of 2 upside packing boxes of second transport mechanism inject, so that the packing box on the second transport mechanism 2 can convey to the preset position of first transport mechanism 1 more smoothly.

As a more preferable implementation manner, when one of the limiting assemblies can be close to or away from the other limiting assembly, or two limiting assemblies can be close to or away from each other, the distance between the two limiting portions 8 is changed to change the width of the conveying channel of the packing boxes on the second conveying mechanism 2, so that the purpose of limiting and guiding the packing boxes to be conveyed is achieved, and meanwhile, the conveying device can be better suitable for conveying the packing boxes with different specifications.

With this structure, the conveying position of the packing box on the second conveying mechanism 2 can be relatively fixed; when the packing box on the second conveying mechanism 2 is conveyed to the first conveying mechanism 1, the packing box can enter a preset area on the first conveying mechanism 1, and accurate positioning of the packing box on the first conveying mechanism 1 is facilitated, so that packing box packaging operation is facilitated.

The structure of the supporting member 9 may not be specifically limited, as long as it is convenient to support the limiting portion 8, and the limiting portion 8 is convenient to move on the upper side of the second conveying mechanism 2 along the direction perpendicular to the conveying direction. In particular, the support 9 is generally a rod-like structure. In order to make the motion process of the limiting assembly more stable, the supporting member 9 may further be provided with a second sliding block, and the second sliding block may be arranged as a structure in sliding fit with the base or other structures on the lower side of the first transmission mechanism 1.

It will be appreciated that the spacing assembly and the clamping assembly may be identical in construction. When the limiting assembly is driven or transmitted by a driving mechanism or a transmission mechanism, the driving mechanism or the transmission mechanism is the same as that of the clamping assembly. For example, the driving/transmission structure of the transmission mechanism can be adopted between the two limiting assemblies to achieve the purpose that the two limiting assemblies are close to or far away from each other.

As a specific implementation manner, a structure of only one supporting member 9 of one limiting assembly is described as an example below. For example, screw holes are formed in the supporting parts 9 of the two limiting assemblies along the width direction of the second conveying mechanism 2, the axis of any screw hole is parallel to the width direction of the second conveying mechanism 2, and the screw thread direction of the screw hole in the supporting part 9 of one limiting assembly is opposite to that of the screw hole in the supporting part 9 of the other limiting assembly.

A second screw rod sequentially passes through the screw holes on the supporting pieces 9 of the two limiting assemblies, the axis of the second screw rod is parallel to the width direction of the second conveying mechanism 2, and the second screw rod is in threaded fit with any supporting piece 9. The second screw rod can be driven to rotate by a driving mechanism such as a motor. The second screw may be a two-way screw; when the second screw rod rotates, the second screw rod can drive the two limiting assemblies to approach or move away from each other.

Specifically, since the frequency of the reciprocating motion of the spacing assembly is low, a driving mechanism may not be provided for the motion of the spacing assembly. For example, for the packing box with the same specification, the position of the limiting component does not need to be changed during the conveying process of the packing box. Therefore, when the structure that the second screw rod is in threaded fit with the limiting assembly is adopted, manual operation can be adopted, so that the second screw rod can rotate. Therefore, the application of the driving mechanism can be simplified, the operation efficiency can be ensured, the structure can be simplified, and the energy consumption can be reduced.

In a specific embodiment, at least two supporting structures are arranged on the lower side of the rotating disc 3, the at least two supporting structures are arranged along the circumferential direction of the rotating disc 3, and any supporting structure is in rotational abutment with the rotating disc 3.

Because the upper side of the rotary table 3 is fixedly provided with the first conveying mechanism 1, the packing box is conveyed on the upper side of the first conveying mechanism 1 and is packaged, and at least two supporting structures can be arranged on the lower side of the rotary table 3 in order to make the rotary table 3 more stable in the rotating process; four are typically provided. The four support structures are evenly arranged on the lower side of the turntable 3 along the circumferential direction of the turntable 3. The support structure may be fixed to the ground or other stable structure on the underside of the turntable 3.

At least one member of the support structure is in rotational abutment with the turntable 3. By adopting the structure, when the turntable 3 does not rotate, the relative position between the supporting structure and the turntable 3 is fixed, and the supporting structure directly plays a role in supporting the turntable 3; when the rotary table 3 rotates, the rotary table 3 and the supporting structure can rotate relatively, and the supporting structure can support without influencing the normal rotation of the rotary table 3.

As one specific implementation, the support structure may include a support base and rollers. A pair of ear plates can be arranged at the top of the supporting seat; the roller is arranged between the pair of ear plates through a rotating shaft; and the axis of the rotating shaft is arranged along the radius direction of the rotating disc 3. The supporting seat can also adopt a structure that the top of the supporting seat is inwards sunken to form a sunken part, and the roller is erected in the sunken part; and the axis of the rotating shaft is arranged along the radius direction of the rotating disc 3.

The embodiment provides a packaging box packaging device, which comprises the transmission structure. Specifically, the structure of the adhesive tape machine may not be particularly limited as long as it can satisfy the purpose of attaching an adhesive tape to the side of the packing box in the rotation process of the packing box.

The present embodiment provides a transmission method, including: acquiring the rotation state of the turntable;

acquiring the existence state of the packing box on the tail end of the second conveying mechanism; and controlling the second conveying mechanism to convey the packing box to the first conveying mechanism according to the rotating state of the turntable and the existence state of the packing box on the second conveying mechanism.

The structure for implementing the transmission process of the method can adopt the transmission structure, and the details are not repeated herein. The first monitoring device 19 arranged at the side of the turntable 3 is used for acquiring the state whether the turntable 3 rotates in place or not, for example, the first monitoring device 19 can acquire the information after the turntable 3 rotates once. Meanwhile, the relation between the number of rotation turns of the turntable 3 and the packaging completion state is set through a controller; for example, one rotation of the turntable 3 may determine that the package is completed, or two rotations of the turntable 3 may be regarded as the package is completed. When the rotation state of the turntable 3 is obtained, the packaging completion state of the packaging box is obtained correspondingly.

And when the number of turns of the rotating disc 3 does not reach one turn or does not reach the corresponding number of turns, the packaging box is regarded as not packaged. It can be understood that, after the packaging operation of any packing box is completed, the controller can zero or count up the number of rotation turns of the rotary disc 3, or perform other control, as long as the packaging box can be packaged, and in the next packaging box packaging process, the number of rotation turns of the rotary disc 3 in the front does not affect the confirmation process of the packaging completion state.

As another realizable mode, according to the rotating speed of the first driving mechanism and the total transmission ratio of the turntable transmission assembly, the information of the states such as the rotating number of the turntable and the like can also be obtained, and according to the information, the packaging completion state of the packaging box can be confirmed. Or, the two modes are combined for use, so that the information of the rotating state of the turntable 3 can be acquired more accurately and conveniently.

After the packaging of the packaging box on the first conveying mechanism 1 is confirmed to be completed, the packaging box on the second conveying mechanism 2 can be continuously conveyed to the first conveying mechanism 1 for the next packaging operation. When it is determined that the packaging operation of the packaging box on the first conveying mechanism 1 is not completed and the packaging box is located at the corresponding position of the second conveying mechanism 2, the second conveying mechanism 2 can stop operating, so that the packaging box on the second conveying mechanism 2 is prevented from being conveyed to the first conveying mechanism 1.

Specifically, a second monitoring device may be disposed at the tail of the second conveying mechanism 2 to obtain the existence state of the upper side packing box of the second conveying mechanism 2, i.e. to confirm whether the packing box exists at the corresponding position on the second conveying mechanism 2.

As a more preferable mode, a third monitoring device can be further disposed at the side of the first conveying mechanism 1, and the third monitoring device is electrically connected with the control device and is used for acquiring the initial positioning position of the packing box on the first conveying mechanism 1. By adopting the mode, when the packing box is conveyed to the corresponding position on the first conveying mechanism 1, the controller can acquire the position information of the packing box on the first conveying mechanism 1, and further control the running states of the first conveying mechanism 1, the turntable 3, the second conveying mechanism 2 and/or other mechanisms so as to conveniently execute the packaging operation or execute the corresponding running state.

Further, the controller can also accurately position the position of the upper side packaging box of the first conveying mechanism 1 according to the running speed of the first conveying mechanism 1 and the distance between the initial positioning position and the preset position of the upper side packaging box of the first conveying mechanism 1, which is acquired by the third monitoring device. For example, the distance between the initial positioning position and the preset position is L; the first transfer mechanism 1 is operated at a speed v. After the packing box is conveyed to the initial positioning position, the operation can be stopped after the packing box continues to operate for a time t equal to L/v, and the packing box on the first conveying mechanism 1 is conveyed to the preset position. By adopting the method, the position of the packing box on the first conveying mechanism 1 can be more accurately positioned, the packing box on the first conveying mechanism 1 is accurately positioned at the preset position, and the efficient and high-quality completion of the packaging operation is more convenient.

According to the conveying structure, the conveying method and the packaging box packaging equipment, the first conveying mechanism is fixedly arranged on the upper side of the rotary table, so that the packaging box can be conveniently conveyed to a preset position; the rotating state of the turntable is acquired through the first monitoring device so as to determine the packaging box packaging completion state, the structure is simple, the monitoring mode is simple and convenient, the operation and the control are convenient, and the packaging box packaging operation is convenient to implement. Set up second monitoring device in second transport mechanism side to the last conveying packing box of first transport mechanism, be convenient for have the packing box to monitor the second transport mechanism afterbody, simultaneously, through the information of first monitoring device and second monitoring device, carry out coordinated control to first transport mechanism, second transport mechanism and carousel, can avoid having a plurality of packing boxes simultaneously and influence encapsulation efficiency on the first transport mechanism to and avoid the packing box extrusion and lead to the condition of packing box damage. Meanwhile, the packaging box can improve the operation efficiency, effectively reduce the idle rate, reduce the energy consumption and prolong the service life in the packaging process of the packaging box, namely the turntable, each conveying mechanism and the adhesive tape machine.
