Abstract

The plastic bag folding machine includes one frame, two turnover boards, two pinching rolls, one inserting and folding board, and elastic pinching roll connecting unit. Its folding process includes the following steps: turning the two turnover boards successively toward the pinching roll by 180 deg to fold the plastic bag, shifting the inserting and folding board downwards to insert the folded plastic bag into between the pinching rolls until passing through the gap between two pinching rolls and to further fold the plastic bag. The present invention has high work efficiency.

Description

technical field [0001] The invention relates to a piece of plastic processing equipment, in particular to a plastic bag folding machine matched with a bag making machine. Background technique [0002] At present, there are many types of plastic bags widely used in the market, such as flat bags, convenience bags, seam bags, etc. These plastic bags are generally processed and manufactured by bag making machines. The bags are sent out in piles by the feeding device, but for the convenience of placement, sale and use, these piles of plastic bags need to be manually folded into long strips one by one, which has the disadvantages of high labor intensity, Low efficiency and other issues. Contents of the invention [0003] The object of the present invention is to provide an automatic plastic bag folding machine, which can automatically fold the piles of plastic bags sent out by the bag making machine into long strips, so as to save manpower and improve work efficiency. [0004]...
