Description

Technical Field

[0001] The utility model relates to the technical field of woven bag production, in particular to an adjustable woven bag bottom sewing device. Background Art

[0002] Woven bags are also called snakeskin bags. They are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene, which are extruded and stretched into flat wires, and then woven and made into bags. The bottom sewing device is generally composed of four parts: the machine head, the machine base, the transmission and the accessories. The production process of woven bags includes the processes of extruding and drawing the plastic raw materials, winding, circular weaving, bag cutting, printing, bottom sewing, and packaging. The bottom sewing is the process of cutting the woven bag into a tube with two ends open, and then sewing one end of the woven bag. The bottom sewing device must be used to sew the bottom of the woven bag;

[0003] The existing woven bag bottom sewing device usually uses a sewing machine to sew one end of the cut woven bag when sewing the woven bag, so as to seal one side of the woven bag. However, the sewing structure on the woven bag bottom sewing device body on the market is fixed to the sewing machine body by bolts, and the position is not convenient to adjust during use. In order to meet the use requirements, woven bags have various specifications, which causes the sewing position of the woven bag to change. Therefore, the existing sewing device is difficult to meet the sewing use of woven bags of different specifications. For this reason, we propose an adjustable woven bag bottom sewing device.
