The right end of the rear side wall of the casing 1 is rotatably connected to the turntable 51. The front side of the turntable 51 is provided with evenly distributed slides 52. The interior of the slide 52 is slidably connected to the support rods 53. The rotating hole in the middle of the turntable 51 is rotatably connected to the rotating column 55. The outer surface of the rotating column 55 is rotatably connected to the evenly distributed pull rods 54. The side of the pull rod 54 away from the center of the turntable 51 is rotatably connected to the vertically adjacent rotating seat of the horizontally adjacent support rod 53 close to the center of the turntable 51. The side of the support rod 53 away from the center of the turntable 51 is mounted in cooperation with the inner wall of the reel 56. The winding mechanism 5 also includes a gear 57. , gear 2 58 and key slot 59, a mounting slot is provided at the right end of the rear side wall of the casing 1, and a gear 1 57 is rotatably connected to the left end of the front side wall of the mounting slot. A key slot 59 is provided at the rear end of the rotating column 55, and gear 1 57 is slidably connected to the inside of the key slot 59 through a key bar. The right end of the front side wall of the mounting slot is rotatably connected to gear 2 58, and gear 2 58 is meshed with gear 1 57. A motor 1 6 is provided at the right end of the rear side wall of the mounting slot, and the front end of the output shaft of motor 1 6 is fixedly connected to the rear end of gear 2 58. The input end of motor 1 6 is electrically connected to the output end of the control switch group 3. An electric push rod 7 is provided at the left end of the rear side wall of the mounting slot, and the front end of the telescopic end of the electric push rod 7 is rotatably connected to the rear end face of the rotating column 55. The input end is electrically connected to the output end of the control switch group 3, and then the reel 56 of the corresponding diameter is replaced according to the required winding diameter, and the reel 56 is sleeved on the outer surface of the support rod 53, and then the electric push rod 7 is turned on by the control switch group 3. The telescopic end of the electric push rod 7 extends forward to push the rotating column 55 forward. Since the rotating column 55 rotates and slides in the rotating hole, the rotating column 55 is pushed forward and the pull rod 54 changes its angle while pushing the support rod 53 to the side away from the center of the turntable 51, so that the support rod 53 slides along the slide groove 52 to the side away from the center of the turntable 51 until it contacts the inner wall of the reel 56. At the same time, the gear 1 57 slides to the rear end of the key groove 59 and keeps meshing with the gear 2 58, and then the plastic film is stuck on the reel. The surface of the drum 56 is then turned on by controlling the switch group 3. The output shaft of the motor 2 8 drives the screw 10 to rotate, and the transmission slider 9 drives the two tension rollers 11 to slide inside the slide groove 2 to adjust the tension of the plastic film. After completion, the motor 1 6 is turned on by controlling the switch group 3. The motor 1 6 drives the gear 2 58 to rotate the transmission gear 1 57 to drive the rotating column 55 to rotate, and the rotating column 55 drives the reel 56 to rotate, thereby realizing the winding of the plastic film. After the winding is completed, the discharge door 4 is opened and the reel 56 with the plastic film is taken out. By changing the angle of the pull rod 54, the pull rod 54 is made to push the support rod 53 outward at the same time to adapt to reels of different diameters, so as to realize the adjustment of the winding diameter of the plastic film, with greater flexibility.

[0024] The working principle of the winding device of a plastic film provided by the present invention is as follows: when winding the plastic film, it is necessary to first pass the plastic film from the feed port 12 into the interior of the machine housing 1, pass between the upper end of the rotating roller 2 and the two tension rollers 11, and then replace the reel 56 of the corresponding diameter according to the required winding diameter, and put the reel 56 on the outer surface of the support rod 53, and then turn on the electric push rod 7 by controlling the switch group 3. The telescopic end of the electric push rod 7 extends forward to push the rotating column 55 forward. Since the rotating column 55 rotates and slides in the rotating hole, it pushes the rotating column 55 forward and drives the pull rod 54 to change its angle, while pushing the support rod 53 to the side away from the center of the turntable 51, so that the support rod 53 moves away from the turntable 51 along the slide groove 52. One side of the center slides until it contacts the inner wall of the reel 56. At the same time, gear 1 57 slides to the rear end of the key slot 59 and maintains engagement with gear 2 58. Then the plastic film is stuck to the surface of the reel 56. The motor 2 8 is turned on by controlling the switch group 3. The output shaft of the motor 2 8 drives the screw 10 to rotate. The transmission slider 9 drives the two tension rollers 11 to slide inside the slide groove 2 to adjust the tension of the plastic film. After completion, the motor 1 6 is turned on by controlling the switch group 3. The motor 1 6 drives the gear 2 58 to rotate the transmission gear 1 57 to drive the rotating column 55 to rotate, and the rotating column 55 drives the reel 56 to rotate, thereby realizing the winding of the plastic film. After the winding is completed, the discharge door 4 is opened and the reel 56 with the plastic film is taken out.
