[0002] A plastic bag is a bag made of plastic. It is light, easy to carry and use, has relatively low manufacturing and production costs, and has certain wear and tear resistance. Plastic bag production requires bag making machines to quickly and continuously produce a large number of plastic bags, and use molds to ensure that the produced plastic bags have specific shapes and sizes to meet design requirements, so that each produced plastic bag has the same shape and size.

[0003] When plastic bags are produced, products of different specifications will appear. Most bag-making machines are not convenient for replacing molds, which affects the production schedule and cannot flexibly respond to market changes and customer needs.
