Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machines, in particular to an automatic edge banding machine for plastic woven bags. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. The weaving density refers to the number of warp and weft yarns in a 100mm×100mm woven fabric. Woven bags often need to be edge-sealed during the production and processing process, which requires an edge-sealing machine.

[0003] Some existing edge sealing machines usually seal one side of the woven bag when sealing the edge of the woven bag, and cannot conveniently seal both sides of the woven bag at the same time. Multiple steps are required to complete the edge sealing of the woven bag, the production efficiency is low, and the edge sealing effect is average. Therefore, an automatic edge sealing machine for plastic woven bags is proposed. Utility Model Content

After the adjustment is completed, the transmission mechanism is started to drive the plastic woven bag to move right, and the lifting block is pushed by the cylinder to make the roller close to and rotate on the upper surface of the plastic woven bag. The adaptability of the pressing can be better through spring compression, and the roller can improve the flattening effect.
