Description

Zipper bag manufacturing equipment {AN APPARATUS FOR MAKING ZIPPER BAG}

The present invention relates to a zipper bag manufacturing apparatus, and more specifically, to a zipper bag manufacturing apparatus for manufacturing a zipper bag having a zipper portion.

A zipper bag is a plastic bag for storing items, and is composed of a zipper provided at the opening of a vinyl member with an internal accommodation space.

In general, a method for manufacturing a zipper bag is to attach a zipper to the opening of a vinyl member through extrusion molding, as disclosed in Patent Publication No. 10-1897503 (2018.09.05.) “Zipper Bag Manufacturing Equipment,” which is a prior art. or integrally molding a separately produced zipper tape into the opening of the film as disclosed in “Zipper Tape Bonding Apparatus” published in Patent Publication No. 10-2017-0134621 (2017.12.05), which is another prior art. The manufacturing method is mainly used.

Here, in order to manufacture a zipper bag, the above-mentioned vinyl member or film is required, and for this purpose, the above-described "zipper bag manufacturing device" extrudes molten synthetic resin raw materials at high temperature, but the sealing part and the zipper part are integrated. An extruder for extruding a hollow molding product; An intake and exhaust nozzle installed at the upper center of the extruder to primarily cool the inner circumferential surface of the hollow molded product extruded at high temperature; and a cooling fan that secondarily cools the outer peripheral surface of the hollow molded product that is primarily cooled by the intake and exhaust nozzles.

However, the conventional manufacturing equipment is simply a device for improving the cooling efficiency of zipper bags extruded at high temperatures, and has the problem of not being able to remove foreign substances generated during the manufacturing process of zipper bags.

In addition, the hollow molded product may be moved in all directions due to external shock or external force, but in this case, there is a problem in that uniform cooling cannot be achieved throughout. Because of this, the hollow molded product cannot form an overall uniform thickness, so a relatively weak part is formed, and this part has a problem in that it is easily torn.

In addition, the hollow molded product is cut in the longitudinal direction on one side by a cutting device, divided into two sides based on the cut portion, and then moved by a plurality of rollers so that the opposing sides come into contact with each other. Generally, the ends of two opposing sides of a hollow molded product are later connected to each other by a sealing device to form an opening. To form this opening, it is preferable that the ends of both sides that are cut are parallel to each other. However, as described above, the hollow molded product has a problem in that when an external impact or external force is generated, the end heights on both sides are positioned at different levels and the hollow molded product moves. Because of this, there was a problem in that defects in the shape of the completed zipper bag later occurred.

In addition, the hollow molded product is sealed on one side in the width direction by a sealing device, and through this, it is molded into individually divided zipper bags. However, when an external impact or external force is generated during the process of moving the hollow molded product for sealing as described above, there is a problem in that the hollow molded product does not have an overall flat shape and some parts are deformed into a folded or distorted shape. Furthermore, when sealing is applied to a deformed part of the hollow molded product during the manufacturing process, the completeness of the sealing is significantly lowered due to the deformed shape, resulting in insufficient finishing of the sealing portion. As a result, zipper packs completed later had problems with defects such as holes forming in the poorly finished sealing area or easily tearing this area.

Korean Patent No. 10-1897503 (2018.09.05.) “Zipper bag manufacturing device”
