[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A PETG film rewinding machine for preventing deviation includes a conveyor box 1. Rollers 2 are installed inside the conveyor box 1, and PETG film 3 is placed outside the rollers 2. A first clamping sleeve 5 is installed in the middle of the conveyor box 1 via a hinge 4. The first clamping sleeve 5 drives a first limiting roller 6 to limit the position of the PETG film 3. When the first limiting roller 6 deviates, it moves the PETG film 3 to one side, ensuring sufficient correction of the PETG film 3. Two sets of first limiting rollers 6 are movably sleeved inside the first clamping sleeve 5. The two sets of first limiting rollers 6 are sequentially installed at the upper and lower ends of the PETG film 3. The first limiting roller 6, with the PETG film 3 confined between two sets of first limiting rollers 6, clamps both ends of the PETG film 3 when the angle of the first limiting roller 6 shifts, preventing wrinkles from forming inside the first limiting roller 6. A set of hydraulic rods 7 is installed on each side inside the conveyor box 1, with the top of the hydraulic rods 7 in contact with the lower end of the first clamp 5. When the detection device detects a shift in the position of the PETG film 3, it controls the hydraulic rod 7 at the shifted end to move upward, while the other set of hydraulic rods 7 moves downward, causing one end of the first limiting roller 6 to tilt upward, ensuring lateral pressure on the PETG film 3. The force, i.e., the misaligned PETG membrane 3, can be corrected, and this correction method will not cause wear to the PETG membrane 3, ensuring the safety of the PETG membrane 3 during correction. A limit sleeve 8 is fixedly connected to the upper part of the conveyor box 1. A crossbar 9 is movably sleeved inside the limit sleeve 8. A detection clamp 10 is fixedly connected to the end of the crossbar 9. The detection clamp 10 is located on the side of the PETG membrane 3. A first sensor 11 and a second sensor 12 are installed inside the detection clamp 10. When the PETG membrane 3 deviates, the first sensor 11 and the second sensor 12 can receive corresponding signals. The first sensor 11 is installed on one side inside the detection clamp 10. A set of second sensors 12 are installed on one side of the upper and lower ends inside the 0. The detection sleeve 10 is sleeved on the side of the PETG film 3. The first sensor 11 is located on the side of the PETG film 3. By installing a crossbar 9 inside the limiting sleeve 8, the position of the detection sleeve 10 is adjusted. The detection sleeve 10 drives the mounting sleeve 13 and the second sensor 12 to move to the outside of the PETG film 3. When the PETG film 3 deviates, the deviated PETG film 3 contacts the first sensor 11. After the first sensor 11 contacts the PETG film 3, a detection signal is generated. The signal drives the hydraulic rod 7 to start. The first sensor 11 installed on the left side drives the left hydraulic rod 7 to move upward.The first sensor 11, triggered on the right, controls the right hydraulic rod 7 to move upward, while the corresponding left hydraulic rod 7 moves downward. This allows the device to automatically correct deviations. Simultaneously, when the tension of the PETG film 3 deviates, the PETG film 3 sinks downward, causing it to collapse. This triggers the start of the lead screw 15, which drives the second clamping sleeve 17 to move up and down, ensuring the PETG film 3 maintains a balanced tension during winding. At both ends of the conveyor box 1, between the two sets of rollers 2, are mounting sleeves 13. An adjusting plate 14 is movably fitted inside the mounting sleeve 13, and a threaded rod 16 is movably fitted inside the adjusting plate 14. The lower end of the threaded rod 16 is fixedly connected to the second clamping sleeve 17. When the second clamping sleeve 17 moves downward, it drives the second limiting roller 18 to push the PETG film 3 downward, ensuring the PETG film 3 maintains a balanced tension.

[0020] Please see Figure 3 The inner side of the second jacket 17 is movably sleeved with two sets of second limiting rollers 18. The second jacket 17 is installed between the two sets of rollers 2. The outer side of the threaded rod 16 is sleeved with a spring 19. The second limiting rollers 18 are installed on the inner side of the second jacket 17. The second limiting rollers 18 clamp the PETG film 3 installed between the two sets of rollers 2. At the same time, the outer side of the threaded rod 16 is equipped with a spring 19. The spring 19 applies elastic potential energy to the second jacket 17, that is, controls the second limiting rollers 18 to maintain a tight and balanced state when pressing the PETG film 3.

[0021] Please see Figure 3 The internal threads at both ends of the adjusting plate 14 are fitted with lead screws 15, which are installed on the side of the conveyor box 1. By activating the lead screws 15, the height of the adjusting plate 14 is adjusted. That is, the height of the second limit roller 18 is adjusted according to the different tightness of the PETG film 3, so as to ensure that the PETG film 3 maintains a tightness balance during the transmission process.

[0022] Please see Figure 1 The first sensor 11 and the second sensor 12 are connected to a control unit, which sequentially controls the start of the hydraulic rod 7 and the lead screw 15. Since the first sensor 11 and the second sensor 12 are connected to the control unit, when the PETG film 3 comes into contact with the first sensor 11 and the second sensor 12, the sensor can be triggered. The control unit controls the start of the hydraulic rod 7 and the lead screw 15. The hydraulic rod 7 corrects the deviation of the PETG film 3, and the lead screw 15 controls the tension balancing device to start, so as to ensure that the PETG film 3 maintains a tension balance when it is wound up.

[0023] Working principle: In use, the PETG film 3 is placed on top of the roller 2. The roller 2 pulls and moves the PETG film 3. A take-up roller is located at the other end of the conveyor box 1, which winds the PETG film 3. During the winding process, if the PETG film 3 becomes loose, the PETG film 3 installed between the two sets of rollers 2 collapses downwards. The collapsed PETG film 3 comes into contact with the second sensor 12, simultaneously activating the control screw 15. The screw 15 drives the adjusting plate 14 downwards, and the adjusting plate 14... Plate 14 drives the second limiting roller 18 to press downwards, that is, the second limiting roller 18 drives the PETG film 3 to press down. After the PETG film 3 is pressed down, it maintains a state of tension balance. When the PETG film 3 deviates, the deviated PETG film 3 contacts the corresponding first sensor 11. At the same time, the first sensor 11 uses the control unit to drive the hydraulic rod 7 on the corresponding side to start. The hydraulic rod 7 drives the first clamp 5 to move downwards. That is, the first limiting roller 6 drives one side of the PETG film 3 to deviate. The deviated PETG film 3 can be automatically corrected.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
