Since this winding mechanism adopts a single-side support, its stability is poor. The structure is as follows: Patent Publication No.: CN212268946U discloses a heat shrink film production winding machine, which is convenient for winding the heat shrink film;

[0004] However, the stability of this structure is poor and cannot meet the needs of daily production. The winding mechanism with double-sided support is not convenient for unloading. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content

[0011] In order to facilitate the support of the heat shrink film during unloading, as a preferred heat shrink film winding mechanism for facilitating unloading of the utility model, movable holes are penetrated through the left front ends of the two vertical plates, and a support roller is movably connected between the two movable holes.

[0012] In order to facilitate unloading, as a preferred heat shrink film winding mechanism for facilitating unloading of the utility model, the diameter of the winding roller is greater than the diameter of the supporting roller.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] See also Figures 1 to 4 A heat shrink film winding mechanism for easy unloading includes a base 1, vertical plates 2 are fixedly connected to the left and right sides of the upper end of the base 1, slots 3 are penetrated in the middle of the upper ends of the two vertical plates 2, and a winding roller 4 is movably connected between the two slots 3;

[0021] A slide groove 5 is provided on the left side of the upper end of the two notches 3 , and the rear ends of the two slide grooves 5 are movably connected to a limit plate 6 , and the front ends of the two slide grooves 5 and the two limit plates 6 are threadedly connected to a limit rod 7 .

[0022] In this embodiment: when in use, the heat shrink film is first rolled up on the outer wall of the winding roller 4, and then the winding roller 4 is placed between the two notches 3, and the two limit plates 6 are rotated to block the upper ends of the two notches 3, and finally the position of the limit plates 6 is fixed by the limit rods 7, and then the winding roller 4 is rotated to facilitate unloading during use. Since the winding roller 4 and the two notches 3 are movably connected, the winding roller 4 can be removed, avoiding the problem of the heat shrink film being rolled up and being inconvenient to unload, thereby improving the unloading efficiency.

[0023] As a technical optimization solution of the utility model, the left end of the winding roller 4 is fixedly connected with a slave gear 8 .

[0024] In this embodiment, a slave gear 8 is provided to drive the winding roller 4 to rotate so as to carry out unloading.

[0025] As a technical optimization solution of the present invention, a fixing seat 9 is fixedly connected to the rear side of the left end of the left vertical plate 2 , and a motor 10 is installed inside the fixing seat 9 .

[0026] In this embodiment, a fixing seat 9 is provided to fix the position of the motor 10. When the motor 10 rotates, the main gear 11 connected thereto is driven to rotate.

[0027] As a technical optimization solution of the present invention, the output end of the motor 10 is fixedly connected with a main gear 11 , and the outer wall of the main gear 11 is meshedly connected with the outer wall of the slave gear 8 .

[0028] In this embodiment, since the main gear 11 is meshedly connected with the slave gear 8 , when the main gear 11 rotates, the slave gear 8 is driven to rotate together.

[0029] As a technical optimization solution of the utility model, movable holes 12 are penetrated through the left front ends of the two vertical plates 2, and a supporting roller 13 is movably connected between the two movable holes 12.

[0030] In this embodiment, by providing a support roller 13, the heat shrinkable film is supported during unloading to prevent the heat shrinkable film from curling, thereby improving the unloading efficiency.

[0031] As a technical optimization solution of the present invention, the diameter of the winding roller 4 is greater than the diameter of the supporting roller 13 .

[0032] In this embodiment, the diameter of the winding roller 4 is set to be larger than the diameter of the supporting roller 13 so as to support the heat shrinkable film and facilitate unloading.

[0033] Working principle: When in use, first roll up the heat shrink film on the outer wall of the winding roller 4, then place the winding roller 4 between the two notches 3, rotate the two limit plates 6 to block the upper ends of the two notches 3, and finally fix the position of the limit plates 6 by the limit rods 7, and then start the motor 10. When the motor 10 rotates, it drives the main gear 11 connected thereto to rotate. Since the outer wall of the main gear 11 is meshed and connected with the outer wall of the slave gear 8, when the main gear 11 rotates, it drives the slave gear 8 to rotate together, thereby causing the winding roller 4 to rotate so that unloading can be carried out when in use. Since the winding roller 4 and the two notches 3 are movably connected, the winding roller 4 can be removed, avoiding the problem of inconvenient unloading of the heat shrink film, thereby improving the unloading efficiency.
