Apparatus for folding and stacking vinyl bags

Abstract

The present invention relates to an apparatus for folding and stacking vinyl bags. More particularly, the present invention relates to an apparatus for folding and stacking vinyl bags, which sequentially folds vinyl bags with heat sealed portions and cut portions, stacks the folded vinyl bags onto a stacking conveyor, and enables the vinyl bags, stacked into a predetermined amount on the stacking conveyor, to be loaded onto a discharge conveyor by an extracting and pressing unit and discharged. The apparatus comprises: a transfer apparatus unit which supplies vinyl bags by means of an upper roller and a lower roller; a stacking apparatus unit on which vinyl bags supplied from the transfer apparatus unit are folded and stacked; a press apparatus unit which presses the top of the stack of the vinyl bags folded and stacked on the stacking apparatus unit; and a fixing and sucking apparatus interposed between the stacking apparatus unit and the lower roller to suck one side of each of the vinyl bags by means of suction holes.

Description

technical field [0001] The invention relates to a plastic bag folding and stacking device, in particular to plastic bags forming a heat-sealed part and a shearing part, which are sequentially folded and stacked on a stacking conveyor belt; after a certain amount of plastic bags are stacked on the stacking conveyor belt, the stacked plastic bags pass through The extracting and pressing part is transported out by the output conveyor. Background technique [0002] Usually, plastic packaging bags (plastic bags) are formed by calendering synthetic resins such as polyvinyl chloride and polyethylene, and after forming cutting lines and heat sealing parts, things can be filled inside. [0003] The food department of large discount supermarkets and department stores that use a large number of plastic bags mainly uses roll bags wrapped with plastic bags. On this roll bag, several welded parts for sealing and cutting parts for easy cutting are formed vertically at regular intervals. W...

AI Technical Summary

Problems solved by technology

[0005] Such stacked plastic bags, the stacking process is not manual but automatic process, but in the stacking process, the discharge of the plastic bags of each layer is not neat, it is difficult to automatically pack, and it is not convenient to use the irregular plastic bags. take out

[0006] In particular, the process of taking out after stacking a certain amount is out of order, so the stacked plastic bags tend to be scattered and difficult to pack

[0007] In addition, although it can be folded during the stacking process, the stacked plastic bags will also be scattered by changes in the surrounding air caused by the operation of various devices.
