Abstract
Description
Technical Field

[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. The main raw material for foreign production is polyethylene, and the main raw material for domestic production is polypropylene. It is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance, good chemical stability, can withstand the erosion of most acids and alkalis, is insoluble in general solvents at room temperature, has low water absorption, and has excellent electrical insulation properties; with so many excellent properties, it is in great demand.
[0003] Woven bags need to be cut during the production process to form uniform lengths. Existing woven bag cutting devices generally use a single cutter to cut the woven bags. Since the woven bags are made of a relatively soft material, using a single cutter to cut them is prone to continuous cutting. Therefore, a plastic woven bag cutting device is needed to solve this problem. Utility Model Content
