[0019] See also Figure 1-4A winding device for a plastic packaging bag comprises two support plates 1, each support plate 1 is provided with a winding shaft 4, the right side of one of the two winding shafts 4 is provided with a plurality of identical slots 15, and the left side of the other winding shaft 4 is fixedly installed with a plurality of identical support shafts 16, and the outer surface of each support shaft 16 is snap-fitted with the inner part of the slot 15, and the bottom surface of each support plate 1 is provided with a base 3, and the upper surface of one of the two bases 3 is provided with two slide grooves 6, and the inner side wall of each slide groove 6 is fixedly installed with two sliding rods 13, and the outer surface of each sliding rod 13 is slidably connected with the inner part of one of the two support plates 1, and a hydraulic push rod 12 is fixedly installed on the left side of one of the two support plates 1, and the left side of the hydraulic push rod 12 is fixedly connected with the right side of one of the two bases 3.

[0020] A driving motor 5 is fixedly installed on the left end of one of the two winding shafts 4, and the right side surface of the driving motor 5 is fixedly connected to the left side surface of one of the two support plates 1. The driving motor 5 is used to drive the winding shaft 4 to rotate, so as to facilitate the winding of the packaging bag. A first bearing 14 is fixedly embedded in the interior of each support plate 1, and the inner wall of each first bearing 14 is fixedly connected to the outer surface of the winding shaft 4. Through the first bearing 14, the winding shaft 4 is supported to rotate, which is beneficial to reduce the wear of the winding shaft 4. Two rollers 2 are commonly provided on the side where the two bases 3 are close to each other, and a roller 7 is fixedly installed on the inner wall of each roller 2. Through the roller 2 and the roller 7, as the packaging bag is wound, the weight of the packaging bag is large, and the roller 2 can assist in the winding of the packaging bag.

[0021] A second bearing 8 is fixedly mounted on the outer surface of each roller 7, and the outer surface of each second bearing 8 is fixedly connected to the inner wall of the base 3. The second bearing 8 supports the rotation of the roller 7, thereby reducing the wear of the roller 7. A synchronous wheel 11 is fixedly mounted on the outer surface of each roller 7, and the outer surfaces of the two synchronous wheels 11 are jointly connected with a synchronous belt 9. A stepper motor 10 is fixedly mounted on the right end of one of the two rollers 7. Through the synchronous wheel 11, the synchronous belt 9 and the stepper motor 10, the roller 7 can be driven to rotate by the synchronous belt 9 and the synchronous wheel 11, and the stepper motor 10 can provide power for it.

[0022] The working principle of the utility model is as follows: when in use, the stepper motor 10 and the drive motor 5 are powered on, and when the packaging bag is rolled up, the packaging bag is mounted on the roll-up shaft 4, and as the drive motor 5 drives the roll-up shaft 4 to rotate, the roll-up shaft 4 can continuously roll up the packaging bag, and as the size and weight of the rolled bag become larger, the stepper motor 10 is started, and the stepper motor 10 drives the roller 7 to rotate via the synchronous belt 9 and the synchronous wheel 11, and then the roller 2 assists the rolling of the packaging bag, and the roller 2 can assist the packaging bag from rolling up. The packaging bag is spread out on the shaft 4. After the winding is completed, in order to facilitate the removal of the wound packaging bag, the hydraulic push rod 12 can be started when the winding is stopped. The hydraulic push rod 12 is retracted, driving the support plate 1 to move to the left. During the movement of the support plate 1, the slide bar 13 will ensure the stability of the movement of the support plate 1. As the support plate 1 moves, the winding shaft 4 can be separated, and then the packaging bag can be conveniently removed from the winding shaft 4. After removal, the winding shaft 4 will be reset, and the support shaft 16 will be inserted into the slot 15, and then the next winding work will be carried out.
