[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] The reeling mechanism in rotating state is used for reeling and unloading;

[0038] The driving mechanism in the driving state is used to drive the retaining ring mechanism to move;

[0039] The retaining ring mechanism in the moving state is used to enable the winding mechanism to wind up films of different widths;

[0040] The No. 1 limiting mechanism in the limiting state is used to fix the driving mechanism;

[0041] The No. 2 limiting mechanism in the limiting state is used to put the No. 1 limiting mechanism in the non-limiting state.

[0042] In this embodiment, when it is necessary to adjust the position of the limit ring 10 according to the width of the film, the No. 1 toggle block 16 in the No. 1 limit mechanism is toggled, and the No. 1 toggle block 16 drives the clamping block 14 to release the gear 13. When the No. 1 toggle block 16 stops toggling, the limit of the No. 1 limit mechanism by the No. 1 toggle block 16 is released, and the No. 2 limit mechanism pops up and clamps the No. 1 limit mechanism, so that the No. 1 limit mechanism is in a non-limiting state. The No. 2 turning handle 9 in the driving mechanism is rotated to rotate the screw rod 11, and the screw rod 11 drives the retaining ring mechanism to move. When the retaining ring 10 is adjusted, the No. 2 toggle block 18 in the No. 2 limit mechanism is toggled to limit the No. 1 limit mechanism again, so that the limit ring 10 will not move when the winding mechanism rotates.

[0043] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the winding mechanism includes a roller 5, a first rotating shaft 6, a first rotating handle 7 and a second rotating shaft 8;

[0044] The first rotating shaft 6 passes through the annular portion at the upper end of the first bracket 1 and is rotatably connected to the first bracket 1. The second rotating shaft 8 passes through the annular portion at the upper end of the second bracket 2 and is rotatably connected to the second bracket 2.

[0045] Both ends of the roller 5 are fixedly connected to one end of the first rotating shaft 6 and the second rotating shaft 8, and the diameter of the roller 5 is larger than the diameter of the first rotating shaft 6 and the second rotating shaft 8. The first turning handle 7 is fixedly connected to the other end of the first rotating shaft 6.

[0046] In this embodiment, when the film needs to be rolled up, the No. 1 handle 7 is rotated, and the rotation of the No. 1 handle 7 drives the No. 1 rotating shaft 6 to rotate, and the rotation of the No. 1 rotating shaft 6 drives the roller 5 and the No. 2 rotating shaft 8 to rotate. The No. 1 rotating shaft 6 rotates at the upper end of the No. 1 bracket 1, and the No. 2 rotating shaft 8 rotates at the upper end of the No. 2 bracket 2. Due to the No. 1 limiting mechanism, the winding mechanism drives the driving mechanism, the baffle ring mechanism, the No. 1 limiting mechanism and the No. 2 limiting mechanism to rotate, so that the baffle ring mechanism will not move. After the winding is completed, the reverse rotation is to unload the film, so that the winding mechanism in the rotating state can be wound up and unloaded.

[0047] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the driving mechanism includes a second turning handle 9 and a screw rod 11;

[0048] One end of the screw rod 11 is rotatably connected to the inside of the roller 5 , and the other end of the screw rod 11 passes through the inner cavity of the second rotating shaft 8 and is rotatably connected to the second rotating shaft 8 and the roller 5 . The second turning handle 9 is fixedly connected to the other end of the screw rod 11 .

[0049] In this embodiment, when it is necessary to drive the retaining ring mechanism to move, the limit of the No. 1 limit mechanism is released, and the No. 2 turning handle 9 is rotated. The rotation of the No. 2 turning handle 9 drives the screw rod 11 to rotate, and the rotation of the screw rod 11 drives the nut block 12 to move, thereby realizing the driving state of the driving mechanism to drive the retaining ring mechanism to move.

[0050] In a further preferred embodiment of the present invention, Figure 1 , 3 -4, the retaining ring mechanism includes a limit retaining ring 10 and a nut block 12;

[0051] The nut block 12 slides inside the roller 5, and both ends of the nut block 12 penetrate the outer wall of the roller 5, and the nut block 12 is threadedly connected to the outer wall of the screw rod 11, and the limit stop ring 10 slides on the outer wall of the roller 5, and the limit stop ring 10 is fixedly connected to both ends of the nut block 12.

[0052] In this embodiment, when it is necessary to roll up films of different widths, the limit of the No. 1 limit mechanism is released, the driving mechanism is rotated, the driving mechanism drives the nut block 12 to move, and the movement of the nut block 12 drives the limit ring 10 to move, so that the moving ring mechanism enables the rolling mechanism to roll up films of different widths.

[0053] In a further preferred embodiment of the present invention, Figure 3 , 5 -7, the first limiting mechanism includes a gear 13, a clamping block 14, a first spring 15 and a first toggle block 16;

[0054] The gear 13 is rotatably connected to the inside of the roller 5, and the gear 13 is fixedly connected to the outer wall of the screw rod 11, the block 14 slides inside the roller 5, and one end of the block 14 in the reset state is meshed with the gear 13, the two ends of the No. 1 spring 15 are fixedly connected to the other end of the block 14 and the inside of the roller 5, one end of the No. 1 toggle block 16 is fixedly connected to the other end of the block 14, and the other end of the No. 1 toggle block 16 penetrates to the side wall of the roller 5 and is slidably connected to the roller 5.

[0055] In this embodiment, when it is necessary to move the retaining ring mechanism, the No. 1 toggle block 16 is toggled, and the No. 1 toggle block 16 drives the clamping block 14 to move in the direction of the No. 1 spring 15. During the movement, the No. 1 spring 15 is squeezed, and the clamping block 14 is released from engagement with the gear 13. At this time, the driving mechanism can be rotated to drive the retaining ring mechanism to move. When limiting is required, the limiting of the No. 2 limiting mechanism is released. Under the elastic force of the No. 1 spring 15, the No. 1 toggle block 16 and the clamping block 14 rebound to their original positions, and the clamping block 14 is engaged with the gear 13. The limiting gear 13 rotates, thereby limiting the rotation of the screw rod 11, thereby realizing the No. 1 limiting mechanism fixing the driving mechanism in the limited state.

[0056] In a further preferred embodiment of the present invention, Figure 5-7 As shown, the second limiting mechanism includes a convex block 17, a second toggle block 18 and a second spring 19;

[0057] The convex block 17 slides inside the roller 5, one end of the second toggle block 18 is fixedly connected to one end of the convex block 17, and the other end of the second toggle block 18 penetrates the side wall of the roller 5, and the two ends of the second spring 19 are fixedly connected to the other end of the convex block 17 and the inside of the roller 5;

[0058] When the second spring 19 is in the squeezed state, the convex block 17 is located at the side wall of the first toggle block 16 . When the second spring 19 is in the non-squeezed state, the convex block 17 is located at the side of the first toggle block 16 close to the gear 13 .

[0059] In the present embodiment, when the No. 1 limiting mechanism is required to limit, the No. 1 toggle block 16 makes the No. 2 spring 19 in an extruded state. When the No. 1 limiting mechanism is not required to limit, the No. 1 toggle block 16 is toggled to make the No. 1 toggle block 16 leave the side wall of the convex block 17. Under the elastic force of the No. 2 spring 19, the convex block 17 drives the No. 2 toggle block 18 to pop out, so that the convex block 17 is located on the side of the No. 1 toggle block 16 close to the gear 13, limiting the movement of the No. 1 toggle block 16, and realizing the limitation of the movement of the No. 1 limiting mechanism. When the limit of the No. 2 limiting mechanism needs to be released, the No. 2 toggle block 18 is toggled to make the No. 2 toggle block 18 drive the convex block 17 to move in the direction of the No. 2 spring 19. During the movement, the No. 2 spring 19 is squeezed, so that the convex block 17 does not limit the movement of the No. 1 toggle block 16, and the No. 2 limiting mechanism in the limited state makes the No. 1 limiting mechanism in the non-limited state.

[0060] In a further preferred embodiment of the present invention, Figure 1 As shown, wheels 3 are installed on both sides of the lower end of the No. 1 bracket 1, and foot pads 4 are installed on both sides of the lower end of the No. 2 bracket 2, and the lower sides of the wheels 3 and the foot pads 4 are in the same plane.
