[0002] Plastic woven bags are made of polypropylene bags and polyethylene bags according to the main material, and are classified into bottom-sewn bags and edge-bottom-sewn bags according to the sewing method. At present, the plastic woven bags are widely used as a packaging material for fertilizers, chemical products and other articles. The main production process is to use plastic raw materials to form flat filaments through extrusion film, cutting and one-way stretching, and then to obtain products through warp and weft weaving. The plastic woven bags are generally called woven bags.

[0003] After the woven bags are woven by a circular weaving machine, a continuous woven bag cylinder is formed. After winding, a woven bag roll is formed. The finished woven bags are formed after cutting and sewing in the later stage. When the woven bags are cut, they need to be unwound by the unwinding equipment into the cutting equipment. In order to avoid the wrinkling phenomenon, the woven bag roll needs to be flattened by the flattening and guiding rollers. The flattening and guiding rollers are arranged in multiple groups. When installing, the staff needs to lead one end of the woven bag roll, and then pass through the multiple groups of flattening and guiding rollers to complete the replacement and installation. It is relatively troublesome. At the same time, the cut woven bags cannot be flattened and conveyed by using the flattening and guiding rollers, and the edge lifting phenomenon is easy to occur. Further improvement can be made. UTILITY MODEL CONTENTS
