Description

Technical Field

[0001] The utility model relates to the field of winding mechanisms, in particular to a winding mechanism for producing plastic bags. Background Art

[0002] The plastic bags on the market mainly include PE, PET, CPP, PVC and OPP. These plastic bags are relatively thin or have high transparency requirements. After production, they need to be rolled up and transported. During the rolling process, a winding device is usually used to roll up the plastic bags. The winding mechanism is a part of the winding device that transports and flattens the plastic bags.

[0003] The current winding mechanism still has the following defects: since there are certain bubbles in the plastic bag after processing, bubbles will be generated during the winding process, and the plastic bag is prone to uneven winding, resulting in curling, entanglement and the like. The plastic bags are uneven after winding, which not only affects the appearance, but also makes the plastic bags loose. The loose plastic bags are easy to loosen, affecting the winding quality of the plastic bags, and the plastic bags cannot be effectively flattened. The requirements for plastic bags of different sizes are also different. When a relatively thin plastic bag is flattened by a roller, it cannot be adjusted, so it cannot play an effective flattening role. When a relatively thick plastic bag is flattened by a roller, it cannot be adjusted, so the flattening roller is pressed too tightly, causing the plastic bag to be crushed or even damaged, and the current winding requirements cannot be met.

[0006] Furthermore, a boss is fixedly provided on the side of the conveying roller, and a connecting structure is fixedly provided on the boss.

[0007] Furthermore, the frame is provided with a square slot.

[0009] Further, the first movable gear is meshed with the second movable gear, the second movable gear is meshed with the third movable gear, and the third movable gear is meshed with the fourth movable gear.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is a winding mechanism for plastic bag production, which can effectively flatten the plastic bags during transportation by arranging flattening rollers and movable rollers, ensuring that the surface of the plastic bags is flat and wrinkle-free, providing good conditions for subsequent winding work, and avoiding the phenomenon of plastic bags curling up and entanglement during transportation.
