Production line for rolling bags with asymmetric bag openings and production method

Abstract

The invention relates to a production line for rolling bags with asymmetric bag openings and a production method. The production line mainly comprises a notching device, a direction-changing device, abottom sealing device and a bag rolling device. The rolling bags are cut into rolling bags with non-flat bag openings through the notching device; the opposite folding direction is changed through the direction-changing device, the notch shapes and the direct-changing opposite folding angles are designed precisely, so that the front-layer bag openings and the rear-layer bag openings after direction changing form staggered peak-valley arrangement; then, the bottoms of the bags are subjected to sealing sticking through the bottom sealing device; and finally, the continuous rolling bags are rolled into rolls through the bag rolling devices. When the rolling bags produced through the production line are used, the edges of the bag openings are staggered in the height direction and in the front-rear direction, and thus finger acting points can be rapidly found to open the rolling bags.

Description

technical field [0001] The invention relates to a production line and a production method of an asymmetric bag opening continuous bag on roll. Background technique [0002] The rolling bag is a common plastic bag in supermarkets and shopping malls. It is used to weigh cooked food, fruit, rice noodles and fresh food. The rolling bag has a relatively simple structure, is easy to produce in large quantities, and is very cheap, which brings great convenience to residents' lives. In daily life, most of the rolling bags that people use are flat pockets. Due to the existence of atmospheric pressure, the films on both sides of the continuous roll bag are adsorbed together, and the flat edge makes it impossible for people to quickly find a point to open the bag, and the bag needs to be rubbed to open it. This wastes people's time, and sometimes it is easy to tear the continuous roll bag due to excessive force, resulting in waste. [0003] To solve this problem, the existing soluti...

Problems solved by technology

Analyzing the above three schemes, it can be found that most of the schemes are relatively complicated in the production process, which increases the production cost

At the same time, the roll-on bag with the above-mentioned structure still has an inconspicuous opening effect and is easily damaged during use, resulting in a waste of resources
