The piston rod of the hydraulic cylinder 3 is fixedly connected to the displacement plate 4. A rack 9 is fixedly connected to the support 2. A first sprocket 5 and a second sprocket 7 are rotatably connected to the displacement plate 4. A gear 8 is fixedly connected to the second sprocket 7, and the gear 8 meshes with the rack 9. The first sprocket 5 is connected to the second sprocket 7 via a chain 6. A blower 15 is connected to the chain 6, and a mounting plate 10 is connected to the displacement plate 4. The plate 10 has two or more through holes, and a punch 11 is installed in the through holes. The punch 11 is provided with a positioning block 12 and a threaded part 13. The top wall of the positioning block 12 abuts against the bottom wall of the mounting plate 10. A nut 14 is threadedly connected to the threaded part 13. The bottom wall of the nut 14 abuts against the top wall of the mounting plate 10. The top wall of the worktable 1 is fixedly connected to a first roller assembly 16, a second roller assembly 17 and a pad 19. The top wall of the pad 19 has two or more grooves 20. The number of grooves 20 is the same as the number of through holes. The heat shrink film body 18 is wound on the first roller assembly 16 and the heat shrink film body 18 is wound on the second roller assembly 17.

[0022] The heat shrink film body 18 is a tear-resistant POF heat shrink film. The tear-resistant POF heat shrink film material includes ternary copolymer polypropylene, which has high strength and transparency and strong tear resistance.

[0023] According to an optional embodiment of the present invention, a laser emitter 21 and a laser receiver 22 are embedded in the inner wall of the groove 20, and the laser emitter 21 and the laser receiver 22 are arranged facing each other.

[0024] According to an optional embodiment of the present invention, the platform 19 is provided with an alarm component, and the alarm component is electrically connected to the laser receiver 22.

[0025] In one optional embodiment of the present invention, the mounting plate 10 is detachably connected to the displacement plate 4.

[0026] In one optional embodiment of this invention, an electrostatic eliminator is embedded in the top wall of the pad 19. The electrostatic eliminator embedded in the top wall of the pad 19 can effectively eliminate static electricity generated by film friction.

[0027] In one optional embodiment of this invention, the hair dryer 15 is connected to the chain 6 via an angle adjustment bracket. The angle adjustment bracket can adjust the blowing angle of the hair dryer 15.

[0028] According to an optional embodiment of the present invention, the first sprocket 5 is rotatably connected to the displacement plate 4 via a bearing assembly, and the second sprocket 7 is rotatably connected to the displacement plate 4 via a bearing assembly.

[0029] According to an optional embodiment of this utility model, the punching needle 11 is made of tungsten steel. Tungsten steel has good wear resistance and corrosion resistance, and high hardness, making it suitable as a material for the punching needle 11.

[0030] According to an optional embodiment of the present invention, a controller 23 is fixedly connected to the top wall of the workbench 1.

[0031] According to an optional embodiment of the present invention, the controller 23 is provided with a human-computer interaction interface.

[0032] Implementation process: The operator turns on the power to the entire device via controller 23. After system initialization, all electrical components enter standby mode. Controller 23 reads preset parameters, such as drilling frequency, and enters the work preparation stage. Controller 23 has data analysis and component control functions and can control the operation of all electrical components.

[0033] The heat shrink film body 18 moves through the cooperation of the first roller assembly 16 and the second roller assembly 17. After the heat shrink film body 18 stops moving, the piston rod on the hydraulic cylinder 3 extends, thereby causing the displacement plate 4 to descend. The heat shrink film body 18 is perforated by the perforating needle 11. After the perforating needle 11 is inserted into the groove 20, the laser emitter 21 emits a laser, and the laser receiver 22 is used to receive the laser emitted by the laser emitter 21. When all laser receivers 22 do not receive the laser, it means that the perforating needle 11 has successfully entered the groove 20, and the alarm component does not work. When one or more laser receivers 22 receive the laser, it means that the perforating needle 11 cannot enter the groove. At this time, the controller 23 controls the hydraulic cylinder 3 to stop running, the device stops, and the alarm component issues an alarm message to remind the user to perform maintenance.

[0034] After the drilling is completed, the displacement plate 4 moves upward. At this time, the rack 9 drives the gear 8 to rotate, thereby causing the second sprocket 7, the first sprocket 5, and the chain 6 to rotate. The chain 6 drives the blower 15 to move to the left. The blower 15 turns on to blow off the impurities on the drilling needles 11. The blower 15 removes impurities from all the drilling needles 11 by moving horizontally.

[0035] When the punch 11 wears out after prolonged use and needs to be replaced, simply rotate the nut 14 to disengage it from the threaded part 13, allowing the punch 11 to be removed from the through hole for replacement. After the new punch 11 is inserted into the through hole, the top wall of the positioning block 12 and the bottom wall of the mounting plate 10 are temporarily fixed together. Then, the nut 14 is rotated into the threaded part 13 to complete the fixation. Replacement is convenient and quick.

[0036] This utility model achieves high-precision punching operation on the heat shrink film body 18 by providing a punching needle 11 on the displacement plate 4 and cooperating with the hydraulic cylinder 3. Combined with the conveying structure of the first roller assembly 16 and the second roller assembly 17, continuous operation can be achieved, improving work efficiency. By providing a laser emitter 21 and a laser receiver 22 in the groove 20 and linking them with the controller 23 and the alarm component, it is possible to accurately monitor whether the punching needle 11 has accurately entered the groove 20, thereby improving the operational safety and automation level of the device and reducing material waste caused by misaligned punching. The upward movement of the piston rod drives the chain 6 to rotate, which in turn drives the blower 15 to move, thus cleaning all the punching pins 11. This avoids the wear problem caused by repeated contact between the baffle and the punching pin 11 in the traditional structure, and significantly extends the service life of the punching pin 11. The punch 11, through the structure of the positioning block 12 and the threaded part 13, combined with the nut 14, can be quickly disassembled and installed independently. The replacement process is simple and efficient, suitable for rapid maintenance needs in mass production scenarios. This solves the problem of needing to replace the entire mounting plate 10 in traditional technologies.

[0037] The components, modules, mechanisms, and devices in this utility model that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
