[0027] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail a film winding mechanism of the present utility model with reference to the accompanying drawings.

[0028] As Figures 1-6 shown, a film winding mechanism of the present utility model includes a support table 1. One end of the support table 1 is provided with a side plate 2. The surface of the side plate 2 is rotatably connected to a first connecting shaft 3 through a bearing. One end of the first connecting shaft 3 is fixedly connected to a rotating column 13. A motor 4 is installed on the side wall of the support table 1 at one end of the side plate 2 through a motor bracket. The motor 4 is connected to the first connecting shaft 3 through a belt transmission assembly 5. By starting the motor 4, under the action of the belt transmission assembly 5, the first connecting shaft 3 drives the rotating column 13 to rotate, so that the film winding cylinder 6 rotates to wind the film. The rotating column 13 has a regular hexagonal structure, and three grooves are arranged on the surface of the rotating column 13 in a circumferential array. One end of the rotating column 13 far from the first connecting shaft 3 is fixedly connected to a second connecting shaft 19. A film winding cylinder 6 is sleeved outside the rotating column 13, and three groups of pressing components for propping up the inner wall of the film winding cylinder 6 are arranged on the surface of the rotating column 13 in a circumferential array. The pressing component includes an electric push rod 17 and a supporting plate 16. The electric push rod 17 is installed in the middle of the groove, and the end of the piston rod of the electric push rod 17 is fixedly connected to the middle of the bottom of the supporting plate 16. Elastic telescopic rods 18 are arranged on both sides of the electric push rod 17 in the groove, and the ends of the elastic telescopic rods 18 are fixedly connected to the bottom of the supporting plate 16. In the initial state, the electric push rod 17 contracts to the shortest state. At this time, the film winding cylinder 6 is sleeved on the rotating column 13, and then the three electric push rods 17 are started simultaneously. The electric push rod 17 pushes the supporting plate 16 to approach and closely contact the inner wall of the film winding cylinder 6, so as to realize the pressing and fixing of the film winding cylinder 6. When the film winding is completed, the three electric push rods 17 are contracted. At this time, the film winding cylinder 6 and the rotating column 13 are in a relaxed state, which is convenient for quickly disassembling the film winding cylinder 6 that has completed the film winding from the rotating column 13, greatly improving the simplicity and convenience of the work, and thus improving the work efficiency. The surface of the supporting plate 16 is an arc surface, and the arc degree of the surface of the supporting plate 16 coincides with the arc degree of the film winding cylinder 6, which is beneficial to complete contact with the inner wall of the film winding cylinder 6.

[0029] A fixed shaft 15 is fixedly connected to one end of the upper surface of the support platform 1 away from the side plate 2. A sleeve 8 is sleeved outside the fixed shaft 15 and is rotatably connected thereto. One side of the sleeve 8 is fixedly connected to a connecting arm 7. A circular plate 9 is arranged at the end of the connecting arm 7. A through hole 10 is arranged on the upper surface of the connecting arm 7. Positioning holes 11 corresponding to the through hole 10 are arranged on the upper surface of the support platform 1. A positioning rod 12 is inserted between the through hole 10 and the positioning hole 11, and a pull ring is arranged at the top of the positioning rod 12. When the connecting arm 7 is rotated so that the rotating shaft 20 is butted against the second connecting shaft 19, the through hole 10 and the positioning hole 11 are on the same straight line. At this time, the positioning rod 12 is inserted into the positioning hole 11 through the through hole 10, and the connecting arm 7 can be locked and positioned, effectively preventing the loosening of the connecting arm 7. And when it is necessary to disassemble and assemble the film winding cylinder 6, the positioning rod 12 is pulled out, and the connecting arm 7 can be rotated. At this time, the rotating shaft 20 is separated from the second connecting shaft 19, and the film winding cylinder 6 can be disassembled and assembled. The whole process is simple and fast to operate and has strong practicability.

[0030] A rotating shaft 20 butted against the second connecting shaft 19 is rotatably connected to the middle part of the surface of the circular plate 9 through a bearing. A plurality of card slots 22 distributed in a circumferential array are arranged at the edge of the end of the second connecting shaft 19. Card teeth 21 corresponding to the card slots 22 one by one are arranged at the edge of the end of the rotating shaft 20. The size of the card teeth 21 matches the size of the card slots 22, and a knob 14 is arranged at the other end of the rotating shaft 20. Through the cooperation between the card teeth 21 and the card slots 22, when the connecting arm 7 is rotated so that the rotating shaft 20 is butted against the second connecting shaft 19, the card teeth 21 will be stuck into the corresponding card slots 22, so that the second connecting shaft 19 and the rotating shaft 20 form a whole. When the first connecting shaft 3 drives the rotating column 13 to rotate, the rotating column 13 drives the second connecting shaft 19 to rotate. At this time, the second connecting shaft 19 will drive the rotating shaft 20 to rotate.
