Description

Technical Field

[0001] This utility model relates to the field of zipper punching devices, specifically a zipper production punching device. Background Technology

[0002] Zipper punching is a key process in zipper production. It is mainly used to process holes on the zipper tape for installing pins or blocks. Before operation, it is necessary to confirm that the zipper specifications are consistent with the production process card, check the air pressure of the equipment and adjust the machine. During operation, the operator inserts the zipper into the punching die in a specific direction. After the first piece quality is confirmed, mass production can begin.

[0003] Current zipper production processes require punching, but a problem exists in actual punching operations. Specifically, most traditional zipper punching machines use automatic feeding mechanisms to transport zippers in a quantitative manner. However, during the punching process, relying solely on tension rollers to tighten the zipper still results in zipper swaying, mainly due to the instability of the tension rollers. Therefore, the inventors urgently need to design a zipper tensioning mechanism to improve the stability of the zipper during the punching process and enhance processing quality. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a zipper punching device to solve the technical problem of zipper shaking caused by the instability of the tensioning mechanism during the zipper punching process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a zipper production punching device, comprising a device body, a driving mechanism installed on the inner side of the device body, the driving mechanism including a driving roller and a driven roller, the driving roller and the driven roller being synchronously connected, a pressure roller mechanism being arranged above the driving roller and the driven roller, a stamping mechanism being installed above the device body, and two sets of the pressure roller mechanisms being distributed on the front and rear sides of the stamping mechanism for pressing and tensioning the zipper.

[0006] By adopting the above technical solution, when the stamping mechanism presses down, the zipper will be subjected to impact force, which can easily cause local deformation or displacement. The pressure roller mechanism located in front of the punching point cooperates with the drive roller to ensure that the zipper is in a taut state when it enters the punching area; while the pressure roller mechanism behind cooperates with the driven roller to effectively resist the thrust generated by punching and prevent the zipper from sliding backward. This rigid tensioning with front and rear clamping fundamentally overcomes the swaying problem that may be caused by the inertia or elasticity of the traditional single tensioning roller.

[0007] Furthermore, one end of the drive roller and the driven roller passes through the main body of the device and is coaxially equipped with a sprocket. A chain is engaged on the outer side of the sprocket to achieve synchronous rotation of the drive roller and the driven roller.

[0008] By adopting the above technical solution, the chain drive has a precise transmission ratio, which can ensure the synchronous rotation of the drive roller and the driven roller, thereby avoiding problems such as asynchronous zipper conveying, wrinkling or stretching caused by transmission slippage or error. This rigid synchronization ensures that the length of the zipper in the interval between the drive roller and the driven roller is precisely controlled, laying a solid foundation for the consistency of the punching spacing.

[0009] Furthermore, a servo motor is installed on one side of the main body of the device, and the output end of the servo motor is connected to the drive roller.

[0010] By adopting the above technical solutions, the servo motor can achieve precise stepless adjustment of speed and accurate control of angular position. The conveying speed of the zipper can be precisely matched with the punching cycle, and fixed-length feeding can be achieved, which directly improves the quality level of the product.

[0011] Furthermore, the pressure roller mechanism includes two sets of support plates arranged in a mirror image. A slider is slidably arranged on the support plate, and a pressure roller is rotatably arranged between the two sets of sliders. An adjusting screw is rotatably connected to the support plate. The adjusting screw is threadedly connected to the slider. Rotating the adjusting screw is used to adjust the longitudinal position of the pressure roller. The zipper is pressed between the drive roller and the pressure roller or the driven roller and the pressure roller to achieve rigid tension and reduce the drift of the zipper during the movement process.

[0012] By adopting the above technical solution, the adjusting screw drive has a self-locking characteristic. Once adjusted to the correct position, the position of the pressure roller will be firmly locked without external force rotating the adjusting screw. This effectively prevents the pressure roller from loosening and floating under long-term vibration conditions, thereby ensuring the long-term stability of the tension. It allows operators to fine-tune the pressure of the pressure roller on the zipper according to the material, thickness and process requirements of the zipper, and find the optimal working point. This ensures sufficient tension to prevent shaking, while avoiding excessive pressure that could cause deformation or surface damage to the zipper.

[0013] Furthermore, the stamping mechanism includes a support frame, on which a pneumatic push rod is mounted, and a stamping die is assembled at the telescopic end of the pneumatic push rod.

[0014] By adopting the above technical solution, the compressed air of the air push rod is used as a power source, which has the characteristics of being clean and pollution-free. It is suitable for zipper products. By adjusting the air pressure and flow rate of the air circuit, the impact force and speed of the stamping die can be easily controlled to meet the punching requirements of zippers made of different materials.

[0015] Furthermore, a CNC panel is provided on the front side of the main body of the device, and the pneumatic actuator and servo motor are both electrically connected to an external power source through a control center.

[0016] By adopting the above technical solution, the control of the pneumatic actuator and the servo motor is integrated into one unit. Through the pre-written program, the timing and parameters of the two core actions of feeding and punching can be precisely coordinated. Operators only need to input the process parameters on the CNC panel to start the entire production process with one click, which greatly reduces the difficulty of operation and the reliance on worker experience, and reduces human error.

[0017] Furthermore, the main body of the device is provided with a limiting mechanism for restricting the position of the zipper. The limiting mechanism includes a support crossbar with an adjustment groove. Two sets of limiting blocks are fixedly installed below the support crossbar by bolts, the bolts passing through the adjustment groove, and a through groove for the zipper to pass through is formed between the two sets of limiting blocks.

[0018] By adopting the above technical solution, the movement and fixation of the bolt in the adjustment groove of the support crossbar can easily adjust the distance between the two sets of limit blocks, thereby adapting to zipper products of different widths, providing great flexibility, ensuring that the device has good versatility, and meeting diverse production needs.

[0019] In summary, the present invention has the following main advantages: 1. This utility model constructs a dual-point rigid tensioning mechanism through the synchronous transmission of the drive roller and the driven roller, and the pressure roller mechanism distributed above the drive roller and the driven roller, which firmly presses the zipper between the rollers, significantly reducing the risk of material shaking or drifting during punching, and directly improving the accuracy and consistency of the punching position. At the same time, the servo motor provides precise power, the sprocket and chain ensure synchronous transmission, and combined with the precise control of the pressure roller position by the adjusting screw in the pressure roller mechanism, the tension force is stable and adjustable, effectively adapting to the production of zippers of different specifications. 2. This utility model uses a limiting mechanism to constrain the lateral displacement of the zipper with an adjustable limiting block, which complements the longitudinal tension of the pressure roller mechanism and together ensures the all-round stability of the zipper during the punching process.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this embodiment: A punching device for zipper production, such as Figure 1-4 As shown, the device includes a main body 1. A drive mechanism 4 is installed inside the main body 1. The drive mechanism 4 includes a drive roller 401 and a driven roller 402. The drive roller 401 and the driven roller 402 are synchronously connected. A pressure roller mechanism 5 is arranged above the drive roller 401 and the driven roller 402. A stamping mechanism 2 is installed above the main body 1. Two sets of pressure roller mechanisms 5 are distributed on the front and rear sides of the stamping mechanism 2 to press and tension the zipper 6. When the stamping mechanism 2 presses down, the zipper 6 will be subjected to impact force, which can easily cause local deformation or displacement. The pressure roller mechanism 5 located in front of the punching point cooperates with the drive roller 401 to ensure... When the zipper 6 enters the punching area, it is in a taut state; while the pressure roller mechanism 5 at the rear cooperates with the driven roller 402 to effectively resist the thrust generated by punching and prevent the zipper 6 from sliding backward. This rigid tensioning with front and rear clamping fundamentally overcomes the swaying problem that may be caused by inertia or elasticity of traditional single tensioning rollers. At the same time, the driving, tensioning and punching functional modules are integrated into a single device body 1, which has a compact structure and reasonable layout. The device body 1 serves as an overall support frame, ensuring the relative positional accuracy between the various mechanisms and reducing the impact of deformation caused by equipment vibration or long-term use on processing accuracy.

[0024] See Figure 2One end of the drive roller 401 and the driven roller 402 passes through the main body 1 of the device and is coaxially mounted with a sprocket 403. A chain 404 meshes with the outer side of the sprocket 403, realizing the synchronous rotation of the drive roller 401 and the driven roller 402. The chain drive has a precise transmission ratio, which can ensure the synchronous rotation of the drive roller 401 and the driven roller 402, thereby avoiding problems such as asynchronous conveying, wrinkling or stretching of the zipper 6 due to transmission slippage or errors. This rigid synchronization ensures that the length of the zipper 6 within the interval between the drive roller 401 and the driven roller 402 is precisely controlled, laying a solid foundation for the consistency of the punching spacing. At the same time, the chain drive structure is robust, can withstand large loads, has a long service life, and low maintenance costs, making it very suitable for the continuous industrial environment of zipper production. Compared with belt drives that may slip or expensive gearbox structures, this solution achieves an excellent balance between cost, reliability and accuracy.

[0025] See Figure 2 A servo motor 405 is installed on one side of the main body 1 of the device. The output end of the servo motor 405 is connected to the drive roller 401. The servo motor 405 can achieve precise stepless adjustment of the rotation speed and precise control of the rotation angle. The conveying speed of the zipper 6 can be precisely matched with the punching cycle, and fixed-length feeding can be achieved, directly improving the quality level of the product. At the same time, the servo motor 405 has good compatibility with the CNC system and can be easily integrated into the automation system controlled by the CNC panel 7. Through program settings, it can flexibly adapt to the production of zippers 6 with different specifications and hole spacing requirements, realizing rapid production changeover.

[0026] See Figure 1 , Figure 2 , Figure 3The pressure roller mechanism 5 includes two sets of support plates 501 arranged in a mirror image. Slider blocks are slidably mounted on the support plates 501, and pressure rollers 502 are rotatably mounted between the two sets of sliders. An adjusting screw 503 is rotatably connected to the support plates 501 and threadedly connected to the sliders. Rotating the adjusting screw 503 adjusts the longitudinal position of the pressure rollers 502. The zipper is pressed between the drive roller 401 and the pressure roller 502, or between the driven roller 402 and the pressure roller 502, achieving rigid tension and reducing drift during zipper movement. The adjusting screw 503 has a self-locking characteristic; once adjusted to the correct position, the pressure rollers 502 will remain stationary without external force when the adjusting screw 503 is rotated. The position is firmly locked, effectively preventing the pressure roller 502 from loosening and floating under long-term vibration conditions, thus ensuring the long-term stability of the tension. This allows operators to fine-tune the pressure of the pressure roller 502 on the zipper 6 according to the material, thickness and process requirements of the zipper 6, and find the optimal working point. This ensures sufficient tension to prevent shaking, while avoiding excessive pressure that could cause deformation or surface damage to the zipper 6. At the same time, the pressure roller mechanism 5 cooperates with the drive roller 401 / driven roller 402 to achieve rigid tension, pressing the zipper 6 tightly onto the roller. Power is directly transmitted to the zipper 6 through strong static friction, greatly reducing the risk of slippage during conveying.

[0027] See Figure 1 , Figure 2 The stamping mechanism 2 includes a support frame 201, on which a pneumatic push rod 202 is mounted. A stamping die is mounted on the telescopic end of the pneumatic push rod 202. The pneumatic push rod 202 uses compressed air as a power source, which is clean and pollution-free, and is suitable for zipper 6 products. By adjusting the air pressure and flow rate of the air circuit, the impact force and speed of the stamping die can be easily controlled to meet the punching requirements of zippers 6 made of different materials. At the same time, mounting the pneumatic push rod 202 on the sturdy support frame 201 ensures the verticality and stability of the stamping action, and avoids the punch from deflecting during the pressing process, thereby ensuring the quality of the punching and the service life of the die. After the pneumatic push rod 202 is connected to the solenoid valve, it can realize high-frequency and high-precision reciprocating motion.

[0028] See Figure 1 , Figure 2The front of the main body 1 of the device is equipped with a CNC panel 7. The pneumatic actuator 202 and the servo motor 405 are electrically connected to an external power supply through the control center. The control of the pneumatic actuator 202 and the servo motor 405 is integrated into one unit. Through a pre-written program, the timing and parameters of the two core actions of feeding and punching can be precisely coordinated. The operator only needs to input the process parameters on the CNC panel 7 to start the entire production process with one click, which greatly reduces the difficulty of operation and the reliance on worker experience, and reduces human error. At the same time, the CNC panel 7 serves as a human-machine interface, which can display the working status of the main body 1, current output, running time and other information in real time, making production management more intuitive and transparent. It also reserves space for further functional expansion, such as connecting sensors to realize fault diagnosis, storing processing programs of multiple products to realize rapid changeover, and connecting to the factory's manufacturing execution system through a network interface.

[0029] See Figure 1 , Figure 2 , Figure 4 The main body 1 of the device is equipped with a limiting mechanism 3 for restricting the position of the zipper. The limiting mechanism 3 includes a support crossbar 301, an adjustment groove 302 on the support crossbar 301, and two sets of limiting blocks 303 fixedly installed below the support crossbar 301 by bolts. The bolts pass through the adjustment groove 302, and a through groove for the zipper 6 to pass through is formed between the two sets of limiting blocks 303. The movement and fixing of the bolts in the adjustment groove 302 of the support crossbar 301 can easily adjust the distance between the two sets of limiting blocks 303, thereby adapting to zipper 6 products of different widths, providing great flexibility, ensuring that the device has good versatility, and meeting diverse production needs. At the same time, the core function of the limiting mechanism 3 is to constrain the lateral position of the zipper 6, prevent it from deviating during the conveying process, and ensure that the zipper 6 always passes directly below the punching die along the preset straight path.

[0030] The implementation principle of this embodiment is as follows: The main body 1 of the device serves as a support structure. The drive mechanism 4 inside is powered by a servo motor 405. Through the meshing of the sprocket 403 and the chain 404, the drive roller 401 and the driven roller 402 rotate synchronously, thereby accurately conveying the zipper 6. On the front and rear sides of the stamping mechanism 2, there is a set of pressure roller mechanisms 5. By rotating the adjusting screw 503, the longitudinal position of the pressure roller 502 is adjusted, and the zipper 6 is rigidly pressed onto the drive roller or the driven roller to form a stable clamping structure, effectively eliminating drift and shaking during transportation. During punching, the pneumatic push rod 202 installed on the support frame 201 drives the stamping die to press down and complete the punching operation. In addition, the actions of the pneumatic push rod 202 and the servo motor 405 can be centrally controlled through the CNC panel 7 to achieve automated operation. The limiting mechanism 3 constrains the lateral position of the zipper through the limiting block 303 that can move along the adjusting groove 302, further ensuring the quality and consistency of punching.

[0031] In this embodiment, the surface material of the drive roller 401, the driven roller 402, and the pressure roller 502 is all rubber.

[0032] In some other embodiments, the diameter of the sprocket at the end of the drive roller 401 is larger than the diameter of the sprocket at the end of the driven roller 402, thereby increasing the rotational speed of the drive roller 401 and reducing the pressure of the pressure roller 502 against the driven roller 402. This facilitates real-time adjustment of the tension when the zipper 6 loosens.
