Conveying system for plastic bags

Abstract

The invention relates to the field of plastic bag preparation, and particularly discloses a conveying system for plastic bags. The conveying system comprises a base frame and a plurality of bearing rollers rotationally mounted in the base frame, and an unfolding area, an extrusion area and a folding area are sequentially arranged on the base frame. By arranging a flapping mechanism, the stacked and cut plastic bags are put into the unfolding area of the base frame, a flapping plate flaps the upper portion of plastic, unfolding rollers at the two sides drive the edges of the plastic bags to move towards the two sides, the plastic bags can be fully unfolded, the edges of the plastic bags are prevented from being folded and bent, and the shapes of the unfolded plastic bags are better; and fluffy plastic bag stacks can be compressed through flapping of the flapping plate, so that the plastic bags enter the extrusion area more conveniently and rapidly in the follow-up process and are not prone to being blocked, and the plastic bags on the upper layer cannot be lifted and stacked.

Description

technical field [0001] The invention relates to a conveying system, in particular to a conveying system for plastic bags, and belongs to the field of plastic bag preparation. Background technique [0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily life and are often used to hold other items. It is widely used because of its advantages of cheapness, light weight, large capacity and easy storage, but its production and use are banned by some countries due to the disadvantages of extremely long degradation cycle and difficult disposal of plastic bags. [0003] In the batch production process of plastic bags, several plastic bags are often stacked together to form a plastic bag stack, which is then cut, and then transported and packaged after cutting. It is difficult for existing plastic bags to be well organized during transportation after ...

AI Technical Summary

Problems solved by technology

Existing plastic bags are difficult to organize well after cutting

The plastic bag stack is relatively fluffy, and the diameter of the strips formed during subsequent folding and packaging is relatively large, which is inconvenient for packaging

And use rubber bands for binding, once the rubber band breaks, it will affect the use of subsequent plastic bags, and it is easy to cause loose damage

Moreover, it is difficult to quickly distinguish different types of plastic bags after they are packaged, which will cause certain troubles for subsequent use.
