[0002] Thermoplastic polyurethane (TPU) has become the core material of automotive paint protection films due to its excellent abrasion resistance, anti-yellowing property, and self-healing characteristics. In the production process of TPU protective vehicle films, rewinding is a key link that determines product quality and production efficiency. However, traditional rewinding equipment has the following problems in the loading and unloading operations of paper core tubes: 1. Most existing TPU protective vehicle film rewinding equipment adopts traditional single-station or double-station rewinding structures. During the installation and disassembly of paper core tubes, it is necessary to rely on manual labor to sleeve the paper core tubes onto the rewinding shafts or remove them from the full-roll film rolls. This manual operation method not only consumes a large amount of time and labor costs but also has operation errors and safety hazards. 2. Although some automated rewinding equipment has introduced paper core tube feeding mechanisms, the existing technology still has complex structures, slow speeds during the existing paper core tube loading and unloading processes, and relatively slow unloading processes, which affect the loading speed and efficiency.

Detailed implementation mode
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] In order to solve the problem that in the background art, most of the existing TPU protective vehicle film winding devices adopt traditional single-station or double-station winding structures. During the installation and disassembly of the paper core tube, it is necessary to rely on manual labor to sleeved the paper core tube onto the winding shaft or remove it from the full-roll film roll. This manual operation method not only consumes a large amount of time and labor costs, but also has operation errors and safety hazards. Although some automatic winding devices have introduced a paper core tube feeding mechanism, the existing technology still has problems such as complex structure, slow speed in the process of feeding and discharging the existing paper core tube, and slow discharging process, which affects the feeding speed and efficiency. Please refer to Figures 1-3 , an on-line splitting and rapid rewinding machine for automotive protective TPU materials, including a base 100. Two groups of moving devices 200 are fixedly arranged on the upper side of the base 100. An auxiliary device 400 is arranged on the left side of the base 100. A transmission device 300 is arranged on the left side of the right moving device 200. A feeding device 500 is arranged on the upper side of the right moving device 200. During use, the feeding device 500 guides the paper core tube, and then the right moving device 200 is started. The right moving device 200 sends the paper core tube onto the auxiliary device 400, and then the auxiliary device 400 drives the paper core tube to rotate for the winding work of the TPU protective film. Then the auxiliary device 400 drives the collected paper core tube to move to the upper side of the left moving device 200, and then it is removed through the left moving device 200 for collection.
[0020] The auxiliary device 400 includes a third frame 410. A rotating plate 420 is rotatably connected to the right side of the third frame 410. A third motor 430 is fixedly installed on the left side of the third frame 410. The driving end of the third motor 430 is fixedly connected to the rotating plate 420. A plurality of third rotating rods 440 are fixedly connected to the right side of the rotating plate 420. Starting the third motor 430 drives the rotating plate 420 to rotate. The rotation of the rotating plate 420 drives the third rotating rods 440 to rotate. By setting the auxiliary device 400, the collected TPU protective film can be driven to move, so that during the processing of the device, the feeding and discharging of the device can be separated, thereby improving the rewinding speed and efficiency of the TPU protective film roll. A retaining ring 441 is fixedly connected to the left side of the third rotating rod 440. A jack is provided on the outer side of the third rotating rod 440. By setting the retaining ring 441, it is convenient to limit the left position of the paper core tube. By providing the jack on the outer side of the third rotating rod 440, even if the paper core roll is not used during the use of the device, the TPU protective film can be limited through the jack, and then the TPU protective film is driven to be wound by rotating the third rotating rod 440, improving the practicability of the device, so that the device can have various forms of winding methods.
[0021] The moving device 200 includes a fixed box 210. Two groups of first rotating rods 220 are rotatably connected to the front and rear side walls of the fixed box 210. A chain belt 230 is connected to the outer sides of the two groups of first rotating rods 220. A first motor 240 is fixedly connected to the rear side of the fixed box 210. The driving end of the first motor 240 is fixedly connected to the left first rotating rod 220. A push block 250 is fixedly connected to the outer side of the chain belt 230. Starting the first motor 240, the left first rotating rod 220 is driven to rotate by the first motor 240. The chain belt 230 is driven to rotate by the left first rotating rod 220. The push block 250 is driven to move by the rotation of the chain belt 230. Then, the paper core tube located on the outer side of the third rotating rod 440 or above the arc-shaped block 530 is moved by the push block 250. By setting the moving device 200, the feeding and discharging work of the paper core tube can be assisted, improving the stability and efficiency of the device. A sprocket is fixedly connected to the outer side of the first rotating rod 220. The chain belt 230 is located outside the sprocket of the first rotating rod 220. By setting the sprocket, the connection tightness between the first rotating rod 220 and the chain belt 230 is improved.
[0022] The transmission device 300 includes a first cylinder 310. The telescopic end of the first cylinder 310 is fixedly connected to a first frame 320. A second cylinder 330 is fixedly installed on the upper side of the first frame 320. The telescopic end of the second cylinder 330 is fixedly connected to a second motor 340. The transmission end of the second motor 340 is fixedly connected to a second rotating rod 350. A clamp 360 is fixedly installed on the left side of the second rotating rod 350. When the first cylinder 310 is started, the first frame 320 is driven by the first cylinder 310 to move back and forth. The second cylinder 330, the second rotating rod 350, and the clamp 360 are driven to move back and forth by the back-and-forth movement of the first frame 320. The second motor 340, the second rotating rod 350, and the clamp 360 are driven to move left and right by the second cylinder 330. The second rotating rod 350 and the clamp 360 are driven to rotate by the second motor 340. The third rotating rod 440 or the paper core tube outside the third rotating rod 440 is driven to rotate by the clamp 360, thereby completing the winding work of the TPU protective film. By setting the transmission device 300, the second rotating rod 350 and the clamp 360 can be driven to adjust their positions and at the same time the second rotating rod 350 and the clamp 360 are driven to rotate. Then, the third rotating rod 440 or the paper core tube outside the third rotating rod 440 is driven to rotate by the second rotating rod 350 and the clamp 360, thereby completing the winding work of the TPU protective film. The telescopic end of the second cylinder 330 is fixedly connected to a fourth frame 341. The second motor 340 is installed on the upper side of the fourth frame 341. A slider is fixedly connected to the lower side of the fourth frame 341. A chute matching the slider of the fourth frame 341 is opened on the upper side of the first frame 320. By setting the fourth frame 341, the stability of the movement of the second motor 340 is improved, and the phenomenon of jitter during the use of the second motor 340 is avoided, improving the stability of the device. The clamp 360 includes a fixed block 361. Multiple chutes are opened on the left side of the fixed block 361. Multiple springs 362 are fixedly connected to the left side of the fixed block 361. A clamping block 363 is fixedly connected to the side of the spring 362 away from the fixed block 361. The spring 362 and the clamping block 363 are both located inside the chute of the fixed block 361. During use, when the fixed block 361 moves to the left, the spring 362 and the clamping block 363 are driven to move to the left. Then, the clamping block 363 is limited by the third rotating rod 440 or the paper core tube outside the third rotating rod 440. Thus, the clamping block 363 presses the spring 362 and sleeves on the outside of the third rotating rod 440 or the paper core tube outside the third rotating rod 440. Then, the third rotating rod 440 or the paper core tube outside the third rotating rod 440 is driven to rotate by the elastic force generated by the deformation of the spring 362. By setting the clamp 360, the third rotating rod 440 or the paper core tube outside the third rotating rod 440 can be rotated, thereby enabling the third rotating rod 440 or the paper core tube outside the third rotating rod 440 to stably wind the TPU protective film. A limiting block 364 is fixedly connected to the right side of the clamping block 363. A chute matching the limiting block 364 is opened on the body of the fixed block 361.The stability of the movement of the clamping block 363 is improved by setting the limit block 364. The left side of the fixed block 361 is fixedly connected with a guiding rod 365. The left side of the guiding rod 365 is tapered. By setting the guiding rod 365, it is convenient to guide and limit the fixed block 361 when the fixed block 361 approaches the third rotating rod 440, improving the stability of the clamping of the third rotating rod 440 or the paper core tube outside the third rotating rod 440 by the fixture 360 of the device, and indirectly improving the stability of the use of the device. The feeding device 500 includes a second frame 510. The front and rear side walls of the second frame 510 are both connected with guiding blocks 520. The upper sides of the guiding blocks 520 are inclined. The lower sides of the guiding blocks 520 are connected with arc-shaped blocks 530. By setting the guiding blocks 520, it is convenient to guide the paper core tube. By setting the arc-shaped blocks 530, it is convenient to limit the paper core tube, facilitating its subsequent movement work.
