Zipper cutting machine

Abstract

The application provides a zipper cutting machine, which comprises a driving mechanism, a clamping mechanism and a cutting mechanism. The clamping mechanism comprises a plurality of clamping assemblies, each of which comprises a base in transmission connection with the driving mechanism and a clamping part arranged on the base. The clamping part comprises two clamping jaw mounting seats arranged oppositely in an up-down direction. The two clamping jaw mounting seats can move close to or away from each other. Each clamping jaw mounting seat is hinged with a clamping jaw. Each clamping jaw is connected with the base through a spring. The cutting mechanism comprises an upper cutter lifting assembly, an upper cutter and a lower cutter. The clamping jaw and the base are elastically connected through the spring. When the cutting mechanism clamps the front end of the zipper tape, the clamping jaw can avoid the upper cutter and quickly reset in the process of moving backward with the clamping mechanism. The clamping mechanism is convenient to change the clamping position of the zipper tape, avoids the separation of the semi-finished zipper tape from the clamping mechanism, and ensures the stability and smoothness of the production process.

Description

Technical Field

[0001] This invention relates to the field of zipper processing technology, and in particular to a zipper cutting machine. Background Technology

[0002] Zippers are typically used at the openings of clothing, bags, and other items to open or close the openings. During the production process, zipper tape is usually quite long and needs to be cut into several finished zipper tapes of specified lengths using a zipper cutter.

[0003] Existing zipper cutting machines include a feeding mechanism, a clamping mechanism capable of horizontal reciprocating movement, and a cutting mechanism positioned along the movement path of the clamping mechanism. The cutting mechanism includes an upper cutter and a lower cutter arranged vertically opposite each other, with the upper cutter positioned close to the lower cutter. The working process of the existing zipper cutting machine is as follows: the clamping mechanism first moves to the discharge port of the feeding mechanism to clamp the front end of the zipper tape, then moves forward to a set distance and stops. Next, the upper cutter in the cutting mechanism approaches the lower cutter and cuts the zipper tape, obtaining a finished section of zipper tape. The upper cutter returns to its original position, and the clamping mechanism continues to clamp the finished zipper tape and moves forward to the unloading position for unloading. Then, it returns to the discharge port of the feeding mechanism to prepare for clamping the front end of the zipper tape again.

[0004] As shown above, each cut by the cutting mechanism simultaneously shapes the rear end of the previous zipper tape and the front end (which is also the front end of the next zipper tape). Therefore, the finished zipper tape produced by this zipper cutting machine has the same shape at both ends. However, when secondary processing of the front end shape of the zipper tape is required (for example, when the front and rear ends of the desired finished zipper tape have different shapes), the existing zipper cutting machine structure cannot meet this production requirement. Summary of the Invention

[0005] In view of the deficiencies in the existing technology, the purpose of this invention is to provide a zipper cutting machine that can meet the production needs of secondary processing of the front end of the zipper tape.

[0006] This invention provides a zipper cutting machine, including a driving mechanism, a clamping mechanism, and a cutting mechanism. The driving mechanism drives the clamping mechanism to move linearly back and forth in a front-to-back direction. The cutting mechanism is disposed in the moving path of the clamping mechanism. The clamping mechanism includes several clamping components. Each clamping component includes a base that is convexly connected to the driving mechanism and a clamping part disposed on the base. The clamping part includes two jaw mounting seats arranged vertically opposite each other. The two jaw mounting seats can move closer to or further away from each other. Each jaw mounting seat has a jaw hinged to it. Each jaw is connected to the base by a spring. The cutting mechanism includes an upper cutter lifting assembly, an upper cutter, and a lower cutter. The upper cutter and the lower cutter are arranged vertically opposite each other. The upper cutter lifting assembly drives the upper cutter to move up and down, closer to or further away from the lower cutter, to complete the clamping or cutting of the zipper tape and obtain the finished zipper tape. The zipper cutting machine provided by this invention addresses the production need for secondary processing of the zipper tape's front end. The working process is modified as follows: first, the clamping mechanism feeds the front end of the zipper tape to the cutting mechanism, and then the cutting mechanism clamps the front end of the zipper tape. The clamping mechanism adjusts its clamping position on the zipper tape, and then the cutting mechanism processes the front end of the zipper tape. To achieve this process, the clamping jaws and the base are elastically connected by springs, allowing the jaws to avoid the upper cutting tool as they move backward with the clamping mechanism. This facilitates the clamping mechanism changing its clamping position on the zipper tape, prevents the semi-finished zipper tape from separating from the clamping mechanism, and ensures a stable and smooth production process.

[0007] Preferably, the upper cutter includes an ultrasonic unit and an upper cutting blade connected to the bottom of the ultrasonic unit. By employing the structure of the ultrasonic unit in conjunction with the upper cutting blade, while cutting the zipper tape, the heat generated by the high-frequency mechanical vibration can be used to heat-seal the cut edge of the zipper tape, preventing the burrs at the end of the zipper tape from unraveling, thereby improving the quality and appearance of the finished zipper tape.

[0008] Preferably, the lower cutting tool includes a first cutting blade and a second cutting blade distributed along the front-to-back direction. The blade shape of the first cutting blade matches the front end shape of the finished zipper tape, and the blade shape of the second cutting blade matches the rear end shape of the finished zipper tape. By providing two cutting blades, the production needs of finished zipper tapes with different front and rear end shapes can be met.

[0009] Preferably, the cutting mechanism further includes a receiving box disposed in front of the first cutting blade, the receiving box being connected to a vacuum source via a dust extraction pipe. After cutting the front end of the zipper tape, the cutting mechanism generates waste material, which falls into the receiving box under the negative pressure of the vacuum source. This arrangement prevents waste material from remaining in the cutting area and affecting subsequent cutting accuracy and the normal operation of the zipper cutter, while also maintaining a clean working environment.

[0010] Preferably, the cutting mechanism further includes a translation drive source for driving the lower cutter to move in the front-to-back direction. The translation drive source drives the lower cutter to translate, changing the cutting blade that cooperates with the upper cutter, thereby meeting the production requirements of finished zipper tapes with different shapes at the front and rear ends.

[0011] Preferably, the upper cutter lifting assembly includes an upper fixed base, a first lifting drive source disposed on the upper fixed base, and an upper movable base slidably connected to the upper fixed base. The first lifting drive source is connected to the upper movable base, and the upper cutter is disposed on the upper movable base. The upper cutter lifting assembly can drive the upper cutter to move up and down, approaching or moving away from the lower cutter, to complete the clamping or cutting of the zipper tape.

[0012] Preferably, the cutting mechanism further includes a lower cutter lifting assembly for driving the lower cutter to move up and down. Providing the lower cutter lifting assembly to drive the lower cutter to move up and down allows for better coordination between the lower and upper cutters, enabling the clamping or cutting of the zipper tape.

[0013] Preferably, the clamping mechanism includes two clamping components, which are symmetrically arranged left and right. Using two symmetrically arranged clamping components allows for simultaneous clamping of both sides of the zipper tape, keeping the zipper tape flat and effectively improving the cutting quality of the zipper tape ends.

[0014] Preferably, the drive mechanism includes a rotary drive source, a driving wheel, a driven wheel, and a conveyor belt. The conveyor belt is wound around the outer periphery of the driving wheel and the driven wheel, and the base is connected to the conveyor belt. This drive mechanism enables the clamping mechanism to smoothly drive linear reciprocating movement in the front-to-back direction.

[0015] Preferably, the base also includes a guide rail extending in the front-to-back direction, and a slider slidably connected to the guide rail is provided at the bottom of the base. The base slides along the guide rail via the slider, which helps to achieve smooth linear movement of the clamping mechanism in the front-to-back direction, providing precise motion guidance and low resistance.

[0016] The zipper cutting machine provided by this invention addresses the production needs of secondary processing of the zipper tape's front end. The working process of the zipper cutting machine is adjusted as follows: first, the clamping mechanism feeds the front end of the zipper tape to the cutting mechanism, and then the cutting mechanism clamps the front end of the zipper tape. The clamping mechanism adjusts its clamping position on the zipper tape, and then the cutting mechanism processes the front end of the zipper tape. To achieve this working process, the clamping jaws and the base are elastically connected by springs, allowing the jaws to avoid the upper cutter and quickly reset as they move backward with the clamping mechanism. This facilitates the clamping mechanism in changing its clamping position on the zipper tape, prevents the semi-finished zipper tape from separating from the clamping mechanism, and ensures a stable and smooth production process. The zipper cutting machine provided by this invention requires minimal structural changes to existing zipper cutting machines and is easy to modify. Attached Figure Description

[0031] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0032] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0035] Figure 3 This is a schematic diagram of the zipper cutting machine of the present invention. In the following description, it is referred to as... Figure 3 The attached diagram serves as a reference for orientation. The direction of movement of the clamping mechanism 1 is defined as the front-back direction, and the guide rail 3 extends along the front-back direction. The distribution direction of the upper tool 21 and the lower tool 22 is defined as the up-down direction, with the upper tool 21 located above the lower tool 22. The direction that is perpendicular to both the front-back and up-down directions is defined as the left-right direction.

[0036] The existing zipper cutting machine includes a feeding mechanism, a clamping mechanism that can move horizontally back and forth, and a cutting mechanism set in the moving path of the clamping mechanism. Its working process is as follows: the clamping mechanism first moves to the discharge port of the feeding mechanism to clamp the front end of the zipper tape, and then moves forward to a set distance and stops. Then, the upper cutter in the cutting mechanism approaches the lower cutter and cuts the zipper tape to obtain a finished zipper tape. The upper cutter returns to its original position, and the clamping mechanism continues to clamp the finished zipper tape and moves forward to the unloading position for unloading. Then it returns to the discharge port of the feeding mechanism to prepare for clamping the front end of the zipper tape.

[0037] As shown above, each cut by the cutting mechanism simultaneously shapes the rear end of the previous zipper tape and the front end of the next zipper tape. Therefore, the finished zipper tape produced by this zipper cutting machine has the same shape at both ends, which can be conventional straight lines. However, when secondary processing of the front end shape of the zipper tape is required, such as producing... Figure 2 When the finished zipper tape 120 shown has different shapes at the front and rear ends, the structure of the existing zipper cutting machine cannot meet this production requirement.

[0038] This invention provides a zipper cutting machine for cutting continuous zipper tape into multiple finished zipper tape segments, and can meet the production needs of secondary processing of the front end of the zipper tape.

[0039] like Figures 1 to 3 , Figure 8 As shown, the zipper cutting machine mainly includes a feeding mechanism 5, a driving mechanism 4, a clamping mechanism 1, and a cutting mechanism 2. The clamping mechanism 1 is used to clamp or release the zipper tape 100; the driving mechanism 4 is used to drive the clamping mechanism 1 to move linearly back and forth; the feeding mechanism 5 is located at the rear end of the moving path of the clamping mechanism 1, and is used to transport the front end of the zipper tape 100 to its own discharge port for easy clamping by the clamping mechanism 1. The feeding mechanism 5 is existing technology and can be a conveyor belt device used for transporting the zipper tape 100, which will not be described in detail here. The cutting mechanism 2 is located in the moving path of the clamping mechanism 1 and is used to clamp or cut the zipper tape 100.

[0040] like Figures 5 to 7 As shown, the clamping mechanism 1 includes several clamping components 11. Each clamping component 11 includes a base 111 that is pulsatorically connected to the drive mechanism 4 and a clamping part 114 disposed on the base 111. That is, the base 111 can reciprocate linearly in the front-back direction under the drive of the drive mechanism 4. The clamping part 114 includes two vertically opposed gripper mounting seats 114a, which can move closer or further apart. Each gripper mounting seat 114a has a gripper 114b hinged to it, and the gripper 114b is connected to the base 111 by a spring 115. When the two gripper mounting seats 114a move closer together, the two grippers 114b clamp the zipper tape; when the two gripper mounting seats 114a move further apart, the two grippers 114b release the zipper tape. The specific form of the clamping part 114 is not limited; pneumatic grippers or electric grippers can be used.

[0041] like Figure 3 and Figure 4 As shown, the cutting mechanism 2 includes an upper cutter lifting assembly 23, an upper cutter 21, and a lower cutter 22. The upper cutter 21 and the lower cutter 22 are arranged vertically opposite each other. The upper cutter lifting assembly 23 drives the upper cutter 21 to move up and down, moving closer to or away from the lower cutter 22, thereby clamping or cutting the zipper tape 100 to obtain the finished zipper tape 120.

[0042] Combination Figure 3 , Figures 8 to 13 As can be seen, the working process of the zipper cutting machine of the present invention is as follows:

[0043] S1. In the initial state, the upper tool 21 is located above the clamping mechanism 1, and the lower tool 22 is located below the clamping mechanism 1, with sufficient clearance between them for the clamping mechanism 1 to pass through.

[0044] S2, feeding the front end of the zipper tape to the cutting mechanism: such as Figure 8 As shown, the clamping mechanism 1 moves to the outlet of the feeding mechanism 5 to clamp the front end of the zipper tape 100, and then moves forward to stop at the first set distance. At this time, the position of the clamping mechanism 1 is as shown. Figure 9 As shown, it is located in front of the upper cutter 21, so that the front end of the zipper tape 100 is directly below the upper cutter 21. The upper cutter lifting assembly 23 drives the upper cutter 21 to descend and approach the lower cutter 22, and the front end of the zipper tape 100 is clamped between the upper cutter 21 and the lower cutter 22.

[0045] S3. The clamping mechanism adjusts the clamping position of the zipper tape: The clamping mechanism 1 releases the front end of the zipper tape 100 and moves backward to a second set distance and stops. At this time, the clamping mechanism 1 is located behind the upper cutter 21 and re-clamps the zipper tape 100. Figure 10As shown, during the backward movement of the clamping mechanism 1, the gripper 114b contacts the upper cutter 21 and rotates forward to avoid it. Then, under the elastic reset action of the spring 115, the gripper 114b quickly returns to its original position to re-grip the zipper tape 100. The spring 115 helps reduce the time spent by the gripper 114b adjusting its clamping position, thus improving the overall working efficiency of the zipper cutting machine.

[0046] S4. The cutting mechanism processes the front end of the zipper tape: such as... Figure 11 As shown, the upper cutter 21 and the lower cutter 22 work together to cut the front end of the zipper tape 100, completing the secondary processing of the front end of the zipper tape 100, and obtaining the desired result. Figure 12 The semi-finished zipper tape 110 with its front end shaped as shown. Then, the upper cutter lifting assembly 23 drives the upper cutter 21 to rise and move away from the lower cutter 22.

[0047] S5. Obtain the finished zipper tape: such as Figure 12 As shown, the clamping mechanism 1 moves forward to a third predetermined distance and stops. The upper cutter lifting assembly 23 drives the upper cutter 21 to descend and approach the lower cutter 22, cutting the semi-finished zipper tape 110 to obtain the desired result. Figure 13 The finished zipper tape 120 shown has a fixed shape at both the front and rear ends. Then, the upper cutter lifting assembly 23 drives the upper cutter 21 to rise and move away from the lower cutter 22. The clamping mechanism 1 continues to clamp the finished zipper tape 120 and moves forward to the unloading position for unloading. Then it returns to the discharge port of the feeding mechanism 5 to prepare for clamping the front end of the zipper tape 100 and producing the next section of finished zipper tape 120.

[0048] As can be seen from the above, the zipper cutting machine provided by the present invention, in order to meet the production needs of secondary processing of the front end of the zipper tape, modifies the working process of the zipper cutting machine as follows: first, the clamping mechanism 1 feeds the front end of the zipper tape 100 to the cutting mechanism 2, and then the cutting mechanism 2 clamps the front end of the zipper tape 100. The clamping mechanism 1 adjusts the clamping position of the zipper tape 100, and then the cutting mechanism 2 processes the front end of the zipper tape 100. To achieve this working process, the present invention elastically connects the gripper 114b and the base 111 through a spring 115, so that the gripper 114b can avoid the upper cutter 21 and quickly reset during the process of moving backward with the clamping mechanism 1. This facilitates the clamping mechanism 1 to change the clamping position of the zipper tape 100, avoids the separation of the semi-finished zipper tape 110 from the clamping mechanism 1, and ensures a stable and smooth production process.

[0049] like Figure 3As shown, in a specific embodiment of the present invention, the upper cutter lifting assembly 23 includes an upper fixed seat 231 with a fixed position, a first lifting drive source 232 disposed on the upper fixed seat 231, and an upper movable seat 233 slidably connected to the upper fixed seat 231. The first lifting drive source 232 is connected to the upper movable seat 233, and the upper cutter 21 is disposed on the upper movable seat 233. The first lifting drive source 232 can be a drive element such as a cylinder, hydraulic cylinder, or linear motor. When the first lifting drive source 232 is working, it can drive the upper movable seat 233 to slide up and down relative to the upper fixed seat 231, thereby driving the upper cutter 21 to perform lifting and lowering movements, realizing the clamping or cutting of the zipper tape.

[0050] The upper cutter 21 includes an ultrasonic unit 212 and an upper cutting blade 211 connected to the bottom of the ultrasonic unit 212. The ultrasonic unit 212 is prior art and includes an ultrasonic generator and a transducer. During operation, the ultrasonic generator outputs a high-frequency alternating current signal, and the transducer converts the electrical signal into a mechanical wave, causing the upper cutter 21 to generate high-frequency mechanical vibration in the vertical direction. By using the structure of the ultrasonic unit 212 and the upper cutting blade 211, while cutting the zipper tape, the heat generated by the high-frequency mechanical vibration can be used to heat-seal the cut edge of the zipper tape, preventing the burrs at the end of the zipper tape from unraveling, thereby improving the quality and appearance of the finished zipper tape.

[0051] The specific form of the lower cutter 22 can be adjusted according to the structure of the finished zipper tape. For example... Figure 1 As shown, when the front and rear ends of the finished zipper tape 120 have the same shape, the lower cutter 22 includes a cutting blade. The shape of the cutting blade edge matches the shape of the front and rear ends of the finished zipper tape 120, and can be straight, curved, zigzag, etc.

[0052] like Figures 2 to 4 As shown, when the front and rear ends of the finished zipper tape 120 have different shapes, the lower cutter 22 includes a first cutting blade 221 and a second cutting blade 222 distributed along the front-rear direction. The first cutting blade 221 is located in front of the second cutting blade 222. The blade shape of the first cutting blade 221 matches the front end shape of the finished zipper tape 120, and the blade shape of the second cutting blade 222 matches the rear end shape of the finished zipper tape 120. The blade shapes of the first cutting blade 221 and the second cutting blade 222 are not limited and can be one or more of straight, curved, and zigzag shapes.

[0053] Meanwhile, the cutting mechanism 2 also includes a translation drive source 27 for driving the lower cutter 22 to move in the front-back direction. During operation, the translation drive source 27 drives the lower cutter 22 to translate, changing the cutting blade that cooperates with the upper cutter 21. Specifically, when processing the front end of the zipper tape, the first cutting blade 221 is positioned directly below the upper cutter 21; when obtaining the finished zipper tape through cutting, the second cutting blade 222 is positioned directly below the upper cutter 21. Those skilled in the art can also, as needed, set an upper cutter translation drive source connected to the upper cutter 21 in the cutting mechanism 2, and have the upper cutter 21 translated by the upper cutter translation drive source, which can also achieve the technical effect of changing the cutting blade that cooperates with the upper cutter 21.

[0054] In a preferred embodiment of the present invention, such as Figure 2 As shown, the finished zipper tape 120 includes a first protrusion 121 at the front end and a second protrusion 122 at the rear end. Both the first protrusion 121 and the second protrusion 122 are arc-shaped and protrude outwards. Correspondingly, the first cutting blade 221 and the second cutting blade 222 are both arc-shaped, and their opening directions are opposite, serving to form the first protrusion 121 and the second protrusion 122, respectively.

[0055] Furthermore, such as Figures 2 to 4 As shown, the cutting mechanism 2 also includes a receiving box 25 disposed in front of the first cutting blade 221. The receiving box 25 is connected to a vacuum source via a dust suction pipe 26. After the zipper cutting machine provided by the present invention cuts the zipper tape 100 to obtain a finished zipper tape 120, a recess 100a matching the shape of the second protrusion 122 will be left at the front end of the zipper tape 100. During the production of the next finished zipper tape 120, the cutting mechanism 2 needs to cut the front end of the zipper tape 100 and remove the portion including the recess 100a as waste. This waste will fall into the receiving box 25 under the negative pressure of the vacuum source. This arrangement can prevent waste residue in the cutting area from affecting the subsequent cutting accuracy and the normal operation of the zipper cutting machine, while also maintaining a clean working environment.

[0056] Furthermore, to facilitate cooperation with the upper cutter 21 and better achieve clamping or cutting of the zipper tape, the cutting mechanism 2 also includes a lower cutter lifting assembly 24 for driving the lower cutter 22 to move up and down. The lower cutter lifting assembly 24 includes a fixed lower base 241, a second lifting drive source 242 disposed on the lower fixed base 241, and a lower movable base 243 slidably connected to the lower fixed base 241. The second lifting drive source 242 is connected to the lower movable base 243, and the lower cutter 22 and translation drive source 27 are both disposed on the lower movable base 243. When the second lifting drive source 242 is working, it drives the lower movable base 243 to slide up and down relative to the lower fixed base 241, thereby driving the lower cutter 22 and translation drive source 27 to move up and down, further improving the flexibility and adaptability of the cutting action to meet the cutting needs of zipper tapes of different specifications and shapes.

[0057] Both the translation drive source 27 and the second lifting drive source 242 can be driven by cylinders, hydraulic cylinders or linear motors.

[0058] like Figures 5 to 7 As shown, in a specific embodiment of the present invention, the zipper cutting machine further includes a guide rail 3 extending in the front-back direction, and a slider 112 slidably connected to the guide rail 3 is provided at the bottom of the base 111. The base 111 slides along the guide rail 3 via the slider 112, thereby realizing the smooth linear movement of the clamping mechanism 1 in the front-back direction, with precise motion guidance and low resistance.

[0059] The drive mechanism 4 includes a rotary drive source 41, a drive wheel 431, a driven wheel 432, and a conveyor belt 42. The conveyor belt 42 is wound around the outer periphery of the drive wheel 431 and the driven wheel 432 and extends in the front-to-back direction. The base 111 of the clamping assembly 11 is provided with a connecting part 113 that connects to the conveyor belt 42. The rotary drive source 41 can be a servo motor or a stepper motor, etc. When the rotary drive source 41 is working, it drives the drive wheel 431 to rotate. The drive wheel 431 drives the driven wheel 432 to rotate through the conveyor belt 42, thereby driving the clamping assembly 11 connected to the conveyor belt 42 to move linearly back and forth in the front-to-back direction. This conveyor belt transmission method has the advantages of smooth transmission, high positioning accuracy, and low noise, which helps to accurately control the conveying distance of the zipper belt.

[0060] Furthermore, the clamping mechanism 1 includes two clamping components 11, which are symmetrically arranged left and right. The two symmetrically arranged clamping components 11 can simultaneously clamp both sides of the zipper tape, keeping the zipper tape flat and effectively improving the cutting quality of the zipper tape ends. The number of clamping components 11 can also be set to one, three, or more according to actual production needs; this invention does not limit this.

[0061] Furthermore, the zipper cutting machine includes two parallel guide rails 3, with a clamping component 11 sliding on each guide rail 3.

[0062] The drive mechanism 4 includes a rotary drive source 41, a drive wheel 431, a driven wheel 432, a first conveyor belt 421, a second conveyor belt 422, a synchronous shaft 44, and two transmission wheels 45. The first conveyor belt 421 is wound around the outer periphery of the drive wheel 431 and the driven wheel 432, and the second conveyor belt 422 is wound around the outer periphery of the two transmission wheels 45. Both the first conveyor belt 421 and the second conveyor belt 422 extend in the front-back direction. The base 111 of one clamping assembly 11 is connected to the first conveyor belt 421, and the base 111 of the other clamping assembly 11 is connected to the second conveyor belt 422. A synchronous wheel 441 is provided at each end of the synchronous shaft 44. One synchronous wheel 441 is drivenly connected to the driven wheel 432, and the other synchronous wheel 441 is connected to one of the transmission wheels 45. When the rotary drive source 41 is working, it drives the drive wheel 431 to rotate. The drive wheel 431 drives the driven wheel 432 to rotate through the first conveyor belt 421. The driven wheel 432 drives one of the transmission wheels 45 to rotate through the synchronous shaft 44. The other transmission wheel 45 rotates under the synchronous action of the second conveyor belt 422, and finally realizes the synchronous movement of the first conveyor belt 421 and the second conveyor belt 422. The two clamping components 11 move synchronously in a straight line reciprocating in the front and back direction.

[0063] The above description is only a preferred embodiment of the present invention.
