Fully automatic valve welding and bag making machine

Abstract

The invention provides a fully automatic valve welding and bag making machine. The lengths of hot-press parts of an upper heating die 9 and a lower heating die 10 of the bag making machine are 1680 mm, a 800 mm long buggy bag can be machined at one time, multi-time delivering is not needed, and 22 finished products are produced every minute; a buckle locating mechanism is arranged on the bag making machine, a position of a buckle is located during conduction from buckle to a membrane material to prevent deviation of the buckle, the composite quality of the buckle and bag membrane is ensured, and then the quality of a product is promised; and the fully automatic valve welding and bag making machine includes a rack, a feeding device, a drafting device, a hole cutting and valve welding device, a buckle composite device, a horizontal sealing device and a cutting device, wherein the front side and the rear side of the buckle composite device are provided with a first material guiding rollerand a second material guiding roller, the buckle locating device and a third material guiding roller are arranged between the buckle composite device and the first material guiding roller, the bucklelocating device includes an upper pressing roller and a swing rod, a ring-type groove matched with the width of the buckle is arranged on the periphery of the upper pressing roller, and a torsion spring sleeves a rotating shaft.

Description

technical field [0001] The invention belongs to the technical field of bag making equipment, and in particular relates to a fully automatic welding valve bag making machine. Background technique [0002] The vacuum compression bag is a kind of storage bag. This kind of storage bag is connected by two films to form a bag body. A valve is set on one of the films, and concave-convex buckles are respectively provided at the mouth of the bag to seal the bag body. When in use, first place the inflated items (such as cotton-padded clothes, quilts, etc.) The volume of the container is reduced, which is beneficial to the storage of items, and isolates the items from the outside air, which can prevent the items from being damp and moldy. [0003] At present, the production and processing of this type of storage bag is mainly completed by a fully automatic bag making machine. Through the bag making machine, one of the two layers of film materials is cut and welded, and then the two la...

Problems solved by technology

[0003] At present, the production and processing of this type of storage bag is mainly completed by a fully automatic bag making machine. Through the bag making machine, one of the two layers of film materials is cut and welded, and then the two layers of film materials are buckled. A series of processing such as bar hot-pressing lamination, horizontal sealing and cutting; among them, the clasp lamination is mainly to fix the clasp hot-press lamination to the film material through the upper and lower high-temperature heating molds. However, it was found in the actual hot-press lamination that When the buckle is transferred from the material guide mechanism to the film material, the position of the buckle is not effectively positioned, so there will be a deviation, which leads to the inability to effectively guarantee the quality of the buckle and the bag film. Thus affecting the product quality of the storage bag
