[0002] A woven bag, also known as a snake skin bag, is a kind of plastic bag used for packaging products. Its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. Plastic woven bags are classified into polypropylene bags and polyethylene bags according to the main materials; they are divided into bottom-sewn bags and side-bottom-sewn bags according to the sewing method. At present, woven bags are widely used as packaging materials for items such as fertilizers and chemical products. Since the development of woven bags to date, the products have developed rapidly and have formed a series of products with diverse varieties and complete specifications. At present, the existing woven bag cutting devices on the market have complex structures, are inconvenient to use, cannot achieve automatic cutting, most of them still require manual labor, the labor intensity of workers is high, the labor cost is high, and the work efficiency is low; the existing woven bag cutting devices cannot quickly fix the woven bag during cutting, and the woven bag is prone to move, thus affecting the product quality.
