[0025] In the specific implementation process, it is particularly worth pointing out that the size of the winding wheel 11 is determined according to the actual use, the winding wheel 11 is supported through the fixing plate 12 and the base 1, the winding wheel 11 is quickly disassembled through the quick-release structure 2, the quick-release structure 2 and the winding wheel 11 are connected together through the fixing structure 3, and the smoothing wheel 13 is driven by the tensioning device 4 to smooth the reflective film, so that the process of winding the reflective film is ensured to be wrinkle-free.

[0026] Further, the quick release structure 2 comprises a fixed block 21, a first gear 22, a second gear 23, a protective shell 24 and a servo motor 25, the fixed block 21 is installed on the outer wall of the winding wheel 11 and is inserted into the inner wall of the fixed plate 12; the first gear 22 is rotatably connected to the outer wall of the fixed block 21 through a bearing; the second gear 23 is meshingly connected to the outer wall of the first gear 22 and is rotatably connected to the outer wall of the fixed plate 12 through a bearing; the protective shell 24 is arranged on the outer wall of the second gear 23 and is fixedly connected to the outer wall of the fixed plate 12; the servo motor 25 is fixedly connected to the outer wall of the protective shell 24 and is fixedly connected to the outer wall of the second gear 23 through a sealed bearing extending into the protective shell 24; wherein the servo motor 25 drives the winding wheel 11 to rotate through the cooperation of the first gear 22 and the second gear 23, the fixed block 21 limits the winding wheel 11, and the protective shell 24 protects the second gear 23, wherein the model of the servo motor 25 is not limited and can meet the actual use condition;

[0027] In the specific implementation process, it is particularly worth pointing out that an opening corresponding to the fixed block 21 is formed in the top of the fixed plate 12, which can stabilize the winding wheel 11 during installation and is convenient, and during installation, the teeth on the first gear 22 are aligned with the teeth on the second gear 23, and after the winding wheel 11 is completely placed on the fixed plate 12, the first gear 22 is completely meshed with the second gear 23, so that when the servo motor 25 drives the second gear 23 to rotate, the winding wheel 11 rotates through the meshing of the second gear 23 and the first gear 22, and the reflective film is wound, and after the reflective film is wound, the winding wheel 11 can be directly lifted, which is more convenient for the staff to use;

[0028] Further, the fixed structure 3 comprises a mounting block 31, a connecting block 32 and a bolt 33, the mounting block 31 is rotatably connected to one side of the fixed block 21 close to the winding wheel 11 through a bearing, and the other side away from the fixed block 21 is inserted into the outer wall of the winding wheel 11; the connecting block 32 is fixedly connected to the outer wall of the mounting block 31; the bolt 33 penetrates the inner wall of the connecting block 32 and is inserted into the inner wall of the winding wheel 11; wherein the winding wheel 11 is installed on the outer wall of the fixed block 21 through the cooperation of the mounting block 31 and the connecting block 32, and the connecting block 32 and the winding wheel 11 are connected together by the bolt 33;

[0029] In the specific implementation process, it is worth pointing out that the outer wall of the fixed block 21 is rotatably connected with the mounting block 31 through a bearing. When the winding wheel 11 is disassembled, the bolt 33 is taken out from the winding wheel 11, and the mounting block 31 is taken out from the winding wheel 11, so that the winding wheel 11 without the winding reflective film can be replaced. Since the mounting block 31 is in the shape of a block, after being inserted into the winding wheel 11, the winding wheel 11 can rotate with the second gear 23 of the outer wall of the fixed block 21. The end of the bolt 33 is provided with an opening, and the opening is in an outward expanding trend. When the bolt 33 is inserted into the winding wheel 11, the end opening of the bolt 33 is tightly abutted against the inner wall of the winding wheel 11 under the action of its own elasticity, so as to fix the bolt 33 and the connecting block 32 on the outer wall of the winding wheel 11.

[0030] Specifically, when the winding device applied to the reflective film is used, when the reflective film is wound, the two ends of the winding wheel 11 are inserted with the mounting block 31, the fixed block 21 is mounted on the outer wall of the winding wheel 11 on both sides, and the bolt 33 is inserted into the connecting block 32 and the winding wheel 11.

The sliding rod 43 is inserted into the inner wall of the sliding block 42 and is fixedly connected to the outer wall of the fixed plate 12. The spring 44 is sleeved on the outer wall of the sliding rod 43 and abuts against the sliding block 42 and the sliding rod 43. Through the cooperation of the spring 44 and the sliding rod 43, the mounting frame 41 drives the flattening wheel 13 to abut against the outer wall of the winding wheel 11, and the sliding rod 43 ensures the stability of the sliding block 42 during movement;

[0032] In the specific implementation process, it is worth pointing out that when the winding wheel 11 winds the reflective film, the thickness of the reflective film will become thicker, and the flattening wheel 13 will move downward, and the mounting frame 41 will drive the sliding block 42 to extrude the spring 44. Under the extrusion force of the spring 44, the flattening wheel 13 is always abutted against the reflective film on the surface of the winding wheel 11, so as to avoid wrinkles of the reflective film;

[0033] Further, the top of the fixing block 21 abuts against the limiting block 14, and the outer wall of the limiting block 14 is rotatably connected to the outer wall of the fixing plate 12 through a pin shaft, and the bottom of the fixing block 21 is inserted with the inserting block 15, and the bottom of the inserting block 15 is fixedly connected to the bottom of the inner wall of the fixing plate 12;

[0034] In the specific implementation process, it is worth pointing out that, in order to ensure that the fixing block 21 is stable when placed, the limiting block 14 is used to abut against it, so as to avoid shaking during rotation, and the inserting block 15 can ensure that the fixing block 21 is kept in the center of the two fixing plates 12 when installed, so as to be stable during winding, and when the winding wheel 11 is disassembled, the limiting block 14 is turned outward, so that the limiting block 14 is separated from the fixing block 21, so that the winding wheel 11 is not affected by the limiting block 14 when moving upward;

[0035] Specifically, on the basis of the above embodiment, when the fixing block 21 is inserted into the inside of the fixing plate 12 on both sides when the winding wheel 11 is placed, the bottom of the fixing block 21 is inserted into the outer wall of the inserting block 15, and after being placed, the limiting block 14 is used to abut against the top of the fixing block 21, so as to ensure that the winding wheel 11 is stable during rotation, and through the extrusion of the spring 44, the flattening wheel 13 is always attached to the surface of the reflective film, so as to ensure that it is flat during winding.

[0036] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
