Plastic bag forming manufacturing method

Abstract

The invention relates to a plastic bag forming manufacturing method which comprises a placing platform, a movable block, a paving mechanisms, a placing mechanism, a winding mechanism, a first positioning roll shaft, a second positioning roll shaft, a hot cutting end and a heat-seal end; a movable block is arranged right above the placing platform; the top of the movable block is connected with a lifting mechanism; the paving mechanisms are symmetrically mounted on the two side walls of the bottom of the movable block; the hot cutting end is arranged on the lower end face of the movable block;the heat-seal end is arranged on the lower end face of the movable block and on the right side of the hot cutting end; the first positioning roll shaft and the second positioning roll shaft are symmetrically mounted on the left and right sides of the movable block and on the upper end face of the placing platform; the winding mechanism is mounted at the left end of the top of the placing platformthrough a bolt; the placing mechanism is mounted at the right end of the top of the placing platform through a bolt; the placing mechanism and the winding mechanism are components with the same structure; and a mounting groove is formed in the movable block. The plastic bag forming manufacturing method has the characteristics of being high in processing quality and practicality.

Description

technical field [0001] The invention relates to the technical field of plastic bag manufacturing methods, in particular to a plastic bag molding manufacturing method. Background technique [0002] Plastic bags are bags made of polypropylene, polyester, nylon, etc. as the main raw materials. They are indispensable items in people's daily life and are often used to hold other items. It is widely used because of its cheap, extremely light weight, large capacity, and easy storage. The long-tube plastic bag is one of many plastic bags. It is processed by heat-sealing and hot-cutting the long-tube plastic film. The advantages obtained are widely used in supermarkets and other large fresh shopping places. [0003] However, the current plastic bag forming method in the market has the following problems in the operation process: a. Before the traditional plastic bag forming method is heat-sealed and hot-cut to the long cylindrical plastic film, the long cylindrical plastic in some ...

Problems solved by technology

[0003] However, the plastic bag forming method in the current market has the following problems in the operation process: a. Before the traditional plastic bag forming method is heat-sealed and hot-cut to the long cylindrical plastic film, the long cylindrical plastic in some areas The surface of the film is not smooth enough. When these flattened long cylindrical plastic films are heat-sealed and hot-cut, the cutting and fusion are prone to lamination, resulting in defective products in the formed plastic bag, that is, the processing quality is poor. There is no effective guarantee; b. When plastic bags are processed, the plastic bags are all wound on the reel. The size of the plastic bag is different, and the model of the reel is also different. The traditional plastic bag molding production The reel clamping device equipped in the method is unique, that is, a clamping device can only be applied to the same type of reel, resulting in low practicability
