Plastic woven bag edgefold shaping machine and method

Abstract

The invention relates to a plastic woven bag edgefold shaping machine and a method. The machine comprises a clamping base, a working electric sliding block, a displacement frame, a synchronizing device, two positioning clamps, a portal frame, a driving cylinder, a pressing device and a mark ironing device. The working electric sliding block is mounted on the clamping base. The displacement frame is arranged on the working electric sliding block. The synchronizing device is mounted in the middle of the displacement frame. The two positioning clamps are mounted at the left and right ends of thesynchronizing device. The mark ironing device is mounted in the middle of the displacement frame. The portal frame is mounted on the displacement frame. The upper end of the portal frame is connectedwith the pressing device through the driving cylinder. By means of the plastic woven bag edgefold shaping machine and the method, the problems that an existing edgefold machine commonly adopts rigid pressing for woven fabric, two pressing dies are adopted for pressing the woven fabric repeatedly, clear folding marks can only be obtained through repeated pressing since the woven fabric is flexiblefabric, and the edgefold shaping effect is poor can be solved.

Description

technical field [0001] The invention relates to the field of plastic woven bag processing, in particular to a plastic woven bag folding and shaping machine and method. Background technique [0002] Plastic woven bags are composed of polypropylene bags and polyethylene bags according to the main materials; according to the sewing method, they are divided into seamed bottom bags and seamed bottom bags. At present, it is widely used as a packaging material for fertilizers, chemical products and other items. Its main production process is to use plastic raw materials to extrude film, cut, and unidirectionally stretch it into flat wire, and weave the product through warp and weft weaving. It is generally called a woven bag. , in the process of making woven bags, the woven cloth is usually placed in the existing folding machine for folding, but the existing folding machine may have the following problems: [0003] Existing edge folding machines usually use rigid pressing on the w...

Problems solved by technology

[0005] The present invention can solve the problem that the existing edge folding machine usually adopts rigid pressing to the woven fabric, and repeatedly presses the woven fabric through two pressing dies. However, since the woven fabric is a flexible fabric, it often needs repeated pressing to produce clear creases. The effect of folding and shaping is poor, and there may be problems such as accidental creasing of the woven fabric during the folding process
