Problems solved by technology
However, the production of woven bags is cumbersome and complicated, and how to make woven bags has become a major problem. Nowadays, it is necessary to manually fold the woven fabric in half and sew it up. The process is cumbersome and complicated. The edges are not neatly cut by hand. The staff folds the woven fabric in half, and the creases are not clear. After the woven bag is made, it is easy to swell and is not easy to stack. Due to operational problems, the woven bag is not flat after the production is completed, and there are wrinkles. , the process takes a long time, labor intensity is high and efficiency is low

The invention relates to a manufacturing and processing method for a woven bag, relates to the technical field of woven bag packaging. According to the method, an automatic woven bag edge folding equipment is used and comprises an operation table and supporting legs for supporting the operation table; a supporting device for supporting the inner side of the woven bag is arranged on the upper surface of the operation table; and a flattening device for unfolding and flattening the woven bag and an edge folding device for folding the edge of the end part of the woven bag are further arranged on the operation table. The method has the effects of high edge folding efficiency, good edge folding quality and high production speed.
Description
technical field [0001] The invention relates to the technical field of woven bag packaging, in particular to a method for making and processing a woven bag. Background technique [0002] Woven bag, also known as snakeskin bag, is a kind of plastic bag used for packaging. Its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. The weaving density of the woven bag refers to the number of warp and weft yarns in the woven fabric of 100mm×100mm. The woven bag can be used in harsh environments. It has the advantages of non-toxicity, flat surface, less damage, better hand feeling, lower freight cost and more beautiful appearance, low price, good economic benefits, reusable multiple times, good environmental protection, etc. . Adapt to various packaging and transportation environments. [0003] In the process of making the existing rated woven bags, there are many folded edges. By folding and sewing the woven bags, the sewing str...
