Automatic plastic bag folding machine and use method thereof

Abstract

The invention discloses an automatic plastic bag folding machine and a use method of the automatic plastic bag folding machine. The automatic plastic bag folding machine is used for folding drawing type plastic bags automatically; the plastic bags produced by a plastic bag producing machine are sent into the automatic plastic bag folding machine for machining, and the folding procedure is completed; and the automatic plastic bag folding machine comprises a feeding and pushing mechanism, a plastic bag folding mechanism, a leftwards-and-rightwards moving mechanism, a forwards-and-backwards moving mechanism, a plastic bag advancing mechanism, a plastic bag folding mechanism and a lifting mechanism which are sequentially arranged on the rack. The use method includes the following steps that the plastic bags produced by the plastic bag producing machine are sent into the feeding and pushing mechanism to be folded by the plastic bag folding mechanism; the plastic bags are folded and then moved leftwards or rightwards by the leftwards-and-rightwards moving mechanism to a plastic bag pre-folding mechanism for pre-folding of creases in the middles of the plastic bags and are conveyed forwards by the forwards-and-backwards moving mechanism; the plastic bags with the creases pre-folded are conveyed to the tail end by the forwards-and-backwards moving mechanism, then are clamped by the plastic bag advancing mechanism and are pushed to the plastic bag folding mechanism for sequential folding of the plastic bags.

Description

technical field [0001] The invention relates to the technical field of plastic bag folding equipment design, in particular to an automatic folding plastic bag machine. Background technique [0002] In the existing technology, the production of pump-out plastic bags (garbage bags) is generally completed by manual folding, similar to the stacking of pumped paper, the packaging and folding efficiency of plastic bags is low, and the stacking is not neat after folding, which is not easy for subsequent packaging and packaging. In this regard, it is necessary to design an automatic machine that can be connected with the plastic bag making machine, and the plastic bags produced by the plastic bag making machine directly enter the plastic bag folding machine, and the plastic bag folding machine folds a certain number of plastic bags into the desired shape. To facilitate packaging, save a lot of manpower and material resources. Contents of the invention [0003] The purpose of the...
