Description

Technical Field

[0001] The utility model relates to the field of plastic woven bag production, in particular to a bottom sewing device for plastic woven bag production. Background Art

[0002] Plastic woven bags are mainly made of polypropylene bags and polyethylene bags; they are divided into bottom-sewn bags and side-sewn bottom-sewn bags according to the sewing method. Currently, they are widely used as a packaging material for fertilizers, chemical products and other items. The main production process is to use plastic raw materials to extrude films, cut, and unidirectionally stretch them into flat wires, and then weave them through warp and weft to obtain the product. During the production process, the bottom of the plastic woven bag needs to be sewn so that the plastic woven bag can be loaded with items. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a fixing auxiliary device for the production of plastic woven bags with the publication number CN218701708U, comprising a workbench, a leg fixedly mounted at the lower end of the workbench, a woven bag arranged above the workbench, two pre-fixing mechanisms arranged near one side of the upper end of the workbench, a baffle fixedly mounted near the other side of the upper end of the workbench, and three electric telescopic columns fixedly mounted on one side of the baffle, and three slide grooves are provided on the outer surface of the upper end of the workbench, the pre-fixing mechanism comprises two L-shaped plates, the two L-shaped plates are fixedly mounted on the upper end of the workbench, two electric telescopic rods are fixedly mounted on the upper end of the L-shaped plate, and the electric telescopic rods penetrate the lower end of the L-shaped plate, a pressing plate is fixedly mounted on the lower end of the electric telescopic rod, and a plurality of groups of limit plates are fixedly mounted on the lower end of the pressing plate. The fixing auxiliary device for the production of plastic woven bags described in the utility model has a good fixing effect and is convenient for bottom sewing of plastic woven bags.

[0004] The above utility model requires that the plastic woven bag be placed under the pre-fixing mechanism, and then the roller is driven by the electric telescopic rod to press the plastic woven bag, and finally the electromagnetic block is used to clamp the plastic woven bag, and finally the electric telescopic column is used to pull the plastic woven bag. Although the bottom sewing work of the plastic woven bag can be completed, the electric telescopic rod needs to be extended and pressed for each group of plastic woven bags. After sewing, the electric telescopic rod needs to be retracted and the plastic woven bag is placed again. When the electric telescopic rod is working, a lot of time is wasted, which reduces work efficiency. At the same time, when the plastic woven bag is placed manually, the position between the woven bag and the sewing machine cannot be stable, which leads to uneven quality of the plastic woven bag, reducing the practicality of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
