The clamping shaft 19 is connected to the winding cylinder 6 through the cooperation between a limiting plate 7 and a limiting clamp 8. The top end of the support plate 1 is connected to a moving plate 11 through two sliding rods 13 and springs 15. Three guiding rollers 12 are rotatably connected to the right side of the moving plate 11. The middle end of the left side of the moving plate 11 is connected to the top side of the support plate 1 through the meshing between a half gear 3 and a toothed plate 14. A first transmission shaft 2 is rotatably connected to the rear end of the left side of the support plate 1. Bevel gears 4 are fixedly connected to the upper and lower ends of the first transmission shaft 2, the rear end of the half gear 3, and the outer wall of the second transmission shaft 5. The upper two bevel gears 4 and the lower two bevel gears 4 are meshed with each other. A motor 10 is installed on the rear end of the left side of the support plate 1 through a fixing frame. The driving end of the motor 10 is fixedly connected to the left end of the second transmission shaft 5;

[0024] Specifically, by driving the rotation of the rotating shaft 16 through the transmission of the second transmission shaft 5 by the motor 10, the waste film of the stretch film vacuum packaging machine can be wound and collected. By passing the waste film around the three guiding rollers 12 in sequence and then winding it around the outer wall of the winding cylinder 6, through the meshing between the half gear 3 and the toothed plate 14, and then cooperating with the sliding and pulling back between the sliding rod 13 and the spring 15, the moving plate 11 and the waste film can be driven to make reciprocating movements in front of the winding cylinder 6, so that the waste film wound around the outer wall of the winding cylinder 6 is evenly wound around the outer wall of the winding cylinder 6, avoiding being wound at the same position and unable to be evenly wound around the outer wall of the winding cylinder 6. At the same time, through the insertion connection between the insertion block 17 and the slot 18, and then cooperating with the limiting plate 7 and the limiting clamp 8, the winding cylinder 6 is clamped on the outer wall of the rotating shaft 16, which is convenient for quickly disassembling the wound winding cylinder 6 and improving the collection efficiency of the waste film.

[0025] Refer to Figures 1 - 3 , the sliding rod 13 located on the left side of the moving plate 11, the left end of the sliding rod 13 is slidably connected to the top end of the support plate 1, a spring 15 is sleeved on the outer wall of the sliding rod 13, one end of the spring 15 is connected to the left side of the moving plate 11, and the other end of the spring 15 is connected to the right side of the support plate 1. The toothed plate 14 located in the middle of the left side of the moving plate 11 and the half gear 3 rotatably connected to the left side of the support plate 1, the half gear 3 and the toothed plate 14 are meshed with each other.

[0026] Specifically, the sliding rod 13 can not only support the moving plate 11 and the three guide rollers 12, but also enable the moving plate 11 to slide on the top of the support plate 1. At the same time, through the cooperation between the spring 15 and the sliding rod 13, the moving moving plate 11 can be pulled back. Then, through the meshing between the half gear 3 and the toothed plate 14, the moving plate 11 makes a reciprocating motion, realizing that the waste film is evenly wound around the outer wall of the winding cylinder 6. At the same time, through the insertion between the insertion block 17 and the insertion slot 18, and then through the cooperation between the limiting plate 7, the limiting clip 8 and the baffle 9, the wound winding cylinder 6 can be quickly disassembled, facilitating the improvement of the collection efficiency of the waste film of the stretch film vacuum packaging machine.

[0027] Working principle: First, the waste film is sequentially wound around the outer walls of the three guide rollers 12, and then the waste film is wound around the outer wall of the winding cylinder 6. By driving the rotation of the rotating shaft 16 through the transmission of the transmission shaft two 5 by the motor 10, the waste film of the stretch film vacuum packaging machine can be wound and collected. At the same time, through the cooperation between the bevel gear 4 and the transmission shaft one 2, the rotation of the rotating shaft 16 can be driven and the rotation of the half gear 3 can be driven at the same time. Then, through the meshing between the half gear 3 and the toothed plate 14, and in cooperation with the sliding and pulling back between the sliding rod 13 and the spring 15, the moving plate 11 and the waste film can be driven to make a reciprocating motion in front of the winding cylinder 6, enabling the waste film to be evenly wound around the outer wall of the winding cylinder 6. At the same time, by sequentially removing the baffle 9, the limiting clip 8 and the limiting plate 7, the wound winding cylinder 6 can be disassembled through the insertion cooperation between the insertion block 17 and the insertion slot 18, facilitating the improvement of the collection efficiency of the waste film.
