[0026] The clamping mechanism includes two strip-shaped through grooves 8, two second hydraulic cylinders 9, two adjusting blocks 10, a pressing shaft 11 and a pressing roller 12. The two strip-shaped through grooves 8 are both opened on the U-shaped frame 3. The two second hydraulic cylinders 9 are respectively fixedly installed in the two strip-shaped through grooves 8. The two adjusting blocks 10 are respectively fixedly installed on the output shafts of the two second hydraulic cylinders 9. The pressing shaft 11 is rotatably installed on the two adjusting blocks 10. The pressing roller 12 is fixedly sleeved on the pressing shaft 11.

[0027] As Figure 2 shown, the detection and adjustment mechanism includes a bidirectional threaded rod 13, a first motor 14, two internally threaded sliders 15 and two deviation rectifying sensors 16. The bidirectional threaded rod 13 is rotatably installed on the two mounting brackets 2. The first motor 14 is fixedly installed on the corresponding mounting bracket 2. The output shaft of the first motor 14 is fixedly connected to one end of the bidirectional threaded rod 13. The two internally threaded sliders 15 are both threadedly sleeved on the bidirectional threaded rod 13. The two deviation rectifying sensors 16 are respectively fixedly installed on the bottoms of the two internally threaded sliders 15;

[0028] By setting the detection and adjustment mechanism, the distance between the two deviation rectifying sensors 16 can be adjusted according to the width of the plastic film, so that the edges of the plastic film can be detected by the two deviation rectifying sensors 16. [[ID=*]]

[0029] As Figure 1 shown, two first vertical plates 17 are fixedly installed on the top of the workbench 1. Two guide rods 18 are rotatably installed on the two first vertical plates 17. Guide rollers 19 are sleeved on the two guide rods 18;

[0030] By setting the first vertical plates 17, the guide rods 18 and the guide rollers 19, the plastic film can be guided during the winding process of the plastic film.

[0031] As Figure 1As shown, two second vertical plates 20 are fixedly installed on the top of the workbench 1. A winding shaft 21 is rotatably installed on the two second vertical plates 20. A winding roller 22 is fixedly sleeved on the winding shaft 21. A second motor 23 is fixedly installed on the corresponding second vertical plate 20. The output shaft of the second motor 23 is fixedly connected to one end of the winding shaft 21;

[0032] By providing the second vertical plate 20, the winding shaft 21, the winding roller 22 and the second motor 23, the plastic film can be wound by the rotation of the winding roller 22.

[0033] As Figure 2 shown, two support sliding rods are fixedly installed between the two mounting brackets 2. Two support sliders are slidably sleeved on each of the two support sliding rods. The four support sliders are all fixedly connected to the U-shaped frame 3;

[0037] The working principle of the deviation rectifying and protecting device for plastic film winding provided by the present utility model is as follows:

[0038] First step: Start the first motor 14. The first motor 14 drives the double-threaded rod 13 to rotate. The double-threaded rod 13 drives the two internally threaded sliders 15 to approach each other. The internally threaded sliders 15 drive the deviation rectifying sensors 16 to approach each other. Thus, the distance between the two deviation rectifying sensors 16 is adjusted according to the width of the plastic film, so as to detect the edges of plastic films with different widths. Start the second motor 23. The second motor 23 drives the winding shaft 21 to rotate. The winding shaft 21 drives the winding roller 22 to rotate so as to wind the plastic film;

[0039] The second step: if it is detected that the plastic film is deflected, when it deflects to the left, start the first hydraulic cylinder 7, and the first hydraulic cylinder 7 drives the shaped frame 3 to move to the right through the rectangular plate 6, thereby driving the plastic film to move to the right through the fixed roller 5 and the pressure roller 12. When it deflects to the right, start the first hydraulic cylinder 7, and the first hydraulic cylinder 7 drives the shaped frame 3 to move to the left through the rectangular plate 6, thereby driving the plastic film to move to the left through the fixed roller 5 and the pressure roller 12. After the plastic film is corrected and rolled up normally, start the second hydraulic cylinder 9, and the second hydraulic cylinder 9 drives the adjustment block 10, the pressure shaft 11 and the pressure roller 12 to move downward, and then start the first hydraulic cylinder 7 to reset the shaped frame 3.
