[0044] A thickness-fixing shaft is rotatably installed inside the U-shaped frame 403, and the bottom of the thickness-fixing shaft and the bottom of the indicator rod 406 overlap with each other, ensuring that when the bottom of the thickness-fixing shaft contacts the top of the rolled protective film, the thickness of the rolled protective film is equal to the height from the top of the winding drum to the bottom of the thickness-fixing shaft.

[0045] The indicator rod 406 is designed as an "L"-shaped structure, and the position of the bottom of the thickness adjustment shaft indicated on the scale line 407 can be easily observed through the indicator rod 406.

[0047] Working principle: When using the protective film winding device, according to Figure 1-5 As shown, firstly, the winding drum is sleeved on the outer side of the four clamping plates 307, and then the second rotating shaft 303 is rotated by the crank 310. Since the second rotating shaft 303 and the pushing block 304 are threadedly connected, and the contact surfaces of the pushing block 304 and the movable block 305 are both inclined, and the movable plate 306 and the through groove 302 constitute a sliding structure, and the clamping rod 308 and the clamping groove 309 constitute a clamping sliding structure, the pushing block 304 moves to the left, and the pushing block 304 pushes the four movable blocks 305 to move away from each other through the inclined surface thereon, and at the same time, the pushing block 304 drives the clamping rod 308 to move inside the clamping groove 309, and then the four movable blocks 305 drive the four clamping plates 307 to move away from each other through the four movable plates 306, so that the outer sides of the four clamping plates 307 are in close contact with the inner side of the winding drum, and the winding drum is quickly fixed;

[0048] Then determine the thickness of the protective film after rolling according to the needs. Figure 1 and Figure 6 As shown, the handle 404 is turned forward or reversed, and then the handle 404 drives the screw rod 402 to rotate. Since the fixed plate 401 and the screw rod 402 are threadedly connected, and the guide rod 405 and the fixed plate 401 are slidably connected, and the lower end of the screw rod 402 is rotatably mounted with a U-shaped frame 403 through a bearing, the U-shaped frame 403 moves upward or downward, and the U-shaped frame 403 drives the indicator rod 406 and the thickness-fixing shaft to move upward or downward at the same time, and the thickness of the protective film after rolling is determined by the bottom of the indicator rod 406 indicating the position on the scale line 407;

[0049] according to Figure 1 As shown, the end of the protective film is glued to the winding drum, and then the servo motor 501 is started. At this time, the servo motor 501 drives the first rotating shaft 2, the clamping plate 307 and the winding drum to rotate simultaneously through the first gear 502 and the second gear 503, so that the protective film is wound on the winding drum. When the top of the winding drum contacts the bottom of the thickness-fixing shaft, it means that the thickness of the protective film after rolling is just right, and the servo motor 501 is stopped;

[0050] according to Figure 1-5As shown, the second rotating shaft 303 is rotated in the opposite direction by the crank 310, so that the push block 304 moves to the right, and the push block 304 simultaneously pulls the four movable blocks 305 to move towards each other through the clamping rod 308 and the clamping slot 309, and then the four movable blocks 305 pull the four clamping plates 307 to move towards each other through the four movable plates 306, so that the outer sides of the four clamping plates 307 are separated from the inner side of the winding drum, so that the winding drum is freed from the restraint, and then the winding drum can be removed from the first rotating shaft 2.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
