Single-film concave-convex chain clipped applying bag making machine

Abstract

The single-film concave-convex clip chain jointing machine is provided with upper and lower cylinders, ironing molds mounted on the pistons in the cylinders, bakelite board between the upper and lower ironing molds, and bag adhering mechanism with punching head mounted on the piston of one cylinder. The present invention has high bag making efficiency, convenient operation and stable performance, and the jointing machine is microcomputer controlled and provided with pneumatic mechanism.

Description

【Technical field】 [0001] The invention relates to a bag making machine, in particular to a bag making equipment for plastic flexible packaging self-sealing bags, in particular to a single-film concave-convex clip chain laminating bag making machine. 【Background technique】 [0002] In the prior art, in the concave-convex clip chain bag making production line, the resin is firstly molded to the extrusion die by the screw, and the clip chain and the film are blown from the same mold. This technology, in a set of production lines It is necessary to configure multiple molds, and because it is a blow mold, its specification range is small, and it cannot be made into a larger bag. It is often necessary to replace the mold. There are too many molds in a production line, and there are limitations in material selection. The flatness of the bag product is not good, and it cannot be printed in multiple colors. If you want to print in multiple colors, you can on...

Problems solved by technology

[0002] In the existing technology, in the concave-convex zipper bag production line, the resin is first pressed to the extrusion die by the screw, and the zipper and the film are blown from the same mold. This technology, in a production line It is necessary to configure multiple molds, and because it is a blow mold, its specification range is small, and it cannot be made into a larger bag. The mold needs to be replaced frequently. There are too many molds in a production line, which has limitations in material selection. The flatness of bag products is not good, and multi-color printing is not possible. If you want multi-color printing, you can only rely on manual bonding of the clip chain to the bag mouth, which greatly reduces production efficiency, and the operation is very troublesome.
