[0009] Through the above technical solution, the operation of the motor drives the second pulley to rotate, and the second pulley drives the first pulley to rotate through the belt, so as to drive the mounting rod fixed to the first pulley to rotate.
[0010] As a further improvement of the above solution, a sleeve is fixedly connected to the top of the bottom plate, a spring is fixedly connected inside the sleeve, the top end of the spring is fixedly connected to a sliding piece, the sliding piece is slidably connected inside the sleeve, and a connecting rod is fixedly connected to the end of the sliding piece away from the spring.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] By rotating the handle clockwise in the present utility model, the handle drives the threaded cylinder to rotate. The rotation of the threaded cylinder will cause the threaded cylinder to move away from the retaining ring, so that the threaded cylinder is detached from the mounting rod, and thus the winding drum can be taken out. A new winding drum is sleeved on the mounting rod, the front surface of the winding drum contacts the back surface of the retaining ring, and then the threaded cylinder is docked with the thread groove on the mounting rod. Then, the handle is rotated counterclockwise, and the handle drives the threaded cylinder to rotate.

[0017] In the present utility model, the PP protective film passes under the second guide roller and above the first guide roller, and is finally fixed at the bottom of the winding drum. Since the height of the top of the first guide roller is higher than the height of the bottom of the winding drum and the top of the second guide roller, the PP protective film will form a certain tension. This tension will push the first guide roller downward, the first guide roller will push the mounting frame to move, the movement of the mounting frame will push the connecting rod to move, and the connecting rod will push the sliding piece to move, thereby compressing the spring. The reaction force of the spring will make the top of the first guide roller closely fit the PP protective film, so as to ensure that sufficient tension is formed during the winding process of the PP protective film and prevent the PP protective film from loosening and causing wrinkles during the winding process.

A fixing frame 2 is fixedly connected to the top of the bottom plate 1. A mounting rod 3 is rotatably connected inside the fixing frame 2. Both ends of the mounting rod 3 penetrate through the outer wall of the fixing frame 2 and extend. A retaining ring 4 is fixedly connected to the outer wall of the mounting rod 3. A winding drum 5 is sleeved on the outer wall of the mounting rod 3. The front surface of the winding drum 5 contacts the back surface of the retaining ring 4. A threaded groove 6 is formed on the bottom plate 1. A threaded cylinder 7 is threadedly connected to the threaded groove 6. The front surface of the threaded cylinder 7 contacts the back surface of the winding drum 5. A handle 8 is fixedly connected to the outer wall of the threaded cylinder 7.
[0027] The fixing frame 2 is in an "L" shape. The inner diameter of the winding drum 5 is the same as the diameter of the mounting rod 3. There are two handles 8, and the two handles 8 are symmetrically arranged with the threaded cylinder 7 as the center.
[0028] A first pulley 9 is fixedly connected to the front end of the mounting rod 3. A belt 10 is rotatably connected to the outer wall of the first pulley 9. A motor 11 is fixedly connected to the outer wall of the fixing frame 2. A second pulley 12 is fixedly connected to the output end of the motor 11. The second pulley 12 and the first pulley 9 are rotationally connected through the belt 10.
[0029] A sleeve 13 is fixedly connected to the top of the bottom plate 1. A spring 14 is fixedly connected inside the sleeve 13. The top end of the spring 14 is fixedly connected to a sliding piece 15. The sliding piece 15 is slidably connected inside the sleeve 13. One end of the sliding piece 15 away from the spring 14 is fixedly connected to a connecting rod 16.
[0030] One end of the connecting rod 16 away from the sliding piece 15 penetrates through the top of the sleeve 13 and extends. One end of the connecting rod 16 away from the sliding piece 15 is fixedly connected to a mounting frame 17. A first guiding roller 18 is rotatably connected to the inner wall of the mounting frame 17.
[0031] The diameter of the sliding piece 15 is larger than the opening diameter of the top of the sleeve 13. The diameter of the connecting rod 16 is smaller than the opening diameter of the top of the sleeve 13. The mounting frame 17 is in a U shape.
[0032] A fixing plate 19 is fixedly connected to the top of the bottom plate 1. There are two fixing plates 19. A second guiding roller 20 is rotatably connected to one side of the two fixing plates 19 close to each other. A base 21 is fixedly connected to the bottom of the bottom plate 1.
[0033] In the embodiment of the present application, the implementation principle of the winding device for processing the PP protective film for electronic products is as follows: When in use, when it is necessary to replace the winding cylinder 5, rotate the handle 8 clockwise. The handle 8 drives the threaded cylinder 7 to rotate. The rotation of the threaded cylinder 7 will cause the threaded cylinder 7 to move away from the retaining ring 4, so that the threaded cylinder 7 is disengaged from the mounting rod 3, and then the winding cylinder 5 can be taken out. A new winding cylinder 5 is sleeved on the mounting rod 3, so that the front surface of the winding cylinder 5 contacts the back surface of the retaining ring 4. Then, the threaded cylinder 7 is docked with the threaded groove 6 on the mounting rod 3. Then, rotate the handle 8 counterclockwise. The handle 8 drives the threaded cylinder 7 to rotate. The rotation of the threaded cylinder 7 will move in the direction close to 4, so that winding cylinders 5 of different sizes can be fixed on the mounting rod 3. The PP protective film passes through below the second guide roller 20 and above the first guide roller 18, and is finally fixed at the bottom of the winding cylinder 5. Since the height of the top of the first guide roller 18 is higher than the height of the bottom of the winding cylinder 5 and the top of the second guide roller 20, the PP protective film will form a certain tension. The tension will push the first guide roller 18 downward. The first guide roller 18 pushes the mounting frame 17 to move. The movement of the mounting frame 17 will push the connecting rod 16 to move. The connecting rod 16 pushes the sliding piece 15 to move, thereby compressing the spring 14. The reaction force of the spring 14 will make the top of the first guide roller 18 closely fit the PP protective film, so as to ensure that sufficient tension is formed during the winding process of the PP protective film, preventing the PP protective film from loosening and causing wrinkles during the winding process. Then, start the motor 11 counterclockwise. The operation of the motor 11 will drive the second belt pulley 12 to rotate. The second belt pulley 12 drives the first belt pulley 9 to rotate through the belt 10. The first belt pulley 9 drives the mounting rod 3 to rotate. The mounting rod 3 drives the winding cylinder 5 to rotate, and thus the winding of the PP protective film can be completed.
[0034] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
