Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag technology, specifically a winding machine for plastic woven bags. Background Technology

[0002] As is well known, woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. Their raw materials are generally polyethylene, polypropylene, and other chemical plastics. In the early stages of plastic woven bag production, woven bags were typically tubular strips. To facilitate the transportation and storage of plastic woven bags, winding machines were often used to wind them up.

[0003] When existing winding machines wind woven bags, they generally fix the strip to the winding roller and then start the motor to wind the strip. However, woven bags are produced in different sizes, which means that winding machines often need to be changed to winding rollers of different lengths according to the different sizes of woven bags. This is time-consuming, labor-intensive, and has low ease of use. Utility Model Content

[0023] See Figures 1-6 A winding machine for plastic woven bags includes a base frame 1, a drive assembly, and a support assembly. A drive motor 2 is mounted on the base frame 1. The output shaft of the drive motor 2 passes through the base frame 1 and is fixedly mounted on a first rotating shaft 3. A square-shaped long rod 4 is fixedly mounted on one end of the first rotating shaft 3. Two winding rollers 5 are sleeved on the outside of the long rod 4. The winding rollers 5 are circular and can slide on the outer wall of the long rod 4. The drive assembly is mounted on the long rod 4 and has an extension assembly. The extension assembly includes at least two first sliding grooves. Each first sliding groove is opened on the long rod 4, and a first slider 6 is slidably mounted in each first sliding groove. A lead screw 7 is rotatably mounted on the inner wall of each first sliding groove. Each first slider 6 has a threaded hole that matches the thread on the corresponding lead screw 7, and the lead screw 7 and the corresponding threaded hole are connected by threads. Each first slider 6 is fixedly mounted to the corresponding winding roller 5. The support assembly is mounted on the base frame 1.

[0024] The drive assembly includes a rotating hole, which is formed on a long rod 4. The long rod 4 has a receiving groove communicating with the rotating hole. A rotating rod 8 is rotatably arranged in the rotating hole. A knob 20 is fixedly arranged at one end of the rotating rod 8. One end of the rotating rod 8 extends into the receiving groove and is fixedly arranged with a first bevel gear 9. Two second bevel gears 10 mesh with the first bevel gear 9. Each second bevel gear 10 is fixedly arranged with a connecting shaft 11. One end of each connecting shaft 11 passes through the long rod 4 and is fixedly arranged with one end of the corresponding lead screw 7.

[0025] By rotating the knob 20, the knob 20 drives the rotating rod 8 to rotate, the rotating rod 8 drives the first bevel gear 9 to rotate, the first bevel gear 9 drives the second bevel gear 10 to rotate, the second bevel gear 10 drives the connecting shaft 11 to rotate, the connecting shaft 11 drives the lead screw 7 to rotate, the lead screw 7 drives the first slider 6 to move, the first slider 6 drives the winding roller 5 to move, so that the two winding rollers 5 move in opposite directions to both sides, thereby increasing the winding area.

[0026] It also includes multiple adjustment slots, each of which is opened on the corresponding roller 5, and a support rod 12 is slidably installed in every two corresponding adjustment slots. The function of the support rod 12 is to support the woven bag and prevent the middle of the woven bag from collapsing.

[0027] It also includes multiple second slide grooves, each of which is opened on the corresponding roller 5 and is connected to the corresponding adjustment groove. Each second slide groove has a second slider 13 slidably arranged in it, and each second slider 13 is fixedly arranged with the corresponding support rod 12. The stability of the support rod 12 can be increased by the cooperation between the second slider 13 and the support rod 12.

[0028] The support assembly includes a second rotating shaft 14 and a limiting groove. The limiting groove is formed on the bottom frame 1, and a limiting plate 15 is slidably arranged in the limiting groove. A sliding plate 16 is fixedly arranged on the limiting plate 15. One end of the sliding plate 16 passes through the bottom frame 1 and is fixedly arranged on a support plate 17. A fixing sleeve 18 is fixedly arranged on the support plate 17.

The second rotating shaft 14 is fixedly arranged on one side of the long rod 4, and one end of the second rotating shaft 14 is inserted into the fixing sleeve 18 and contacts each ball bearing 19. After the woven bag is rolled up, the worker can move the support plate 17. The support plate 17 drives the sliding plate 16 to move, the sliding plate 16 drives the limiting plate 15 to move, and at the same time, the support plate 17 drives the fixing sleeve 18 to move, so that the fixing sleeve 18 is disengaged from the second rotating shaft 14, thereby making it easier for the worker to pull out the woven bag roll on the rolling roller 5.

[0029] Working principle:

[0030] When using this winding machine for plastic woven bags, first place the machine in the desired position. When adjusting the distance between the two winding rollers 5, the operator turns knob 20. Knob 20 drives rotating rod 8 to rotate, which in turn drives first bevel gear 9 to rotate. First bevel gear 9 drives second bevel gear 10 to rotate, which in turn drives connecting shaft 11 to rotate. Connecting shaft 11 drives lead screw 7 to rotate, which in turn drives first slider 6 to move. First slider 6 moves winding roller 5, causing the two winding rollers 5 to move in opposite directions. The woven bag is then fixed onto the roller 5 by the worker, and the drive motor 2 is started. The output shaft of the drive motor 2 drives the first rotating shaft 3 to rotate, the first rotating shaft 3 drives the long rod 4 to rotate, the long rod 4 drives the roller 5 to rotate, and the roller 5 drives the woven bag to be rolled up. When the rolling is completed, the worker pulls the support plate 17, the support plate 17 drives the sliding plate 16 to move, the sliding plate 16 drives the limiting plate 15 to move, and at the same time the support plate 17 drives the fixing sleeve 18 to move, so that the fixing sleeve 18 is disengaged from the second rotating shaft 14, and the woven bag roll can be disassembled.
