A blow molding device for the production of plastic packaging bags

Abstract

The invention discloses a blow molding device for plastic packaging bag production, which belongs to the technical field of plastic processing, and comprises a casing. A side casing and an adjusting motor are fixedly installed on the side wall of the casing. A rotating shaft is fixedly installed, and an installation component is fixedly installed at one end of the rotating shaft, which is used for the stable installation of the first forming shell and the second forming shell, and one side of the mounting component is provided with the first forming shell and the second forming shell; in the present invention , by setting a coolant tank outside and through effective linkage design, the coolant in the coolant tank can automatically flow into the molding shell, which can quickly reduce the temperature of the inner surface of the molding shell, which is helpful for high-temperature blow molding After the material is quickly released from the mold, the design is ingenious, and the final expansion effect in the blow molding process of the material can be used to realize the automatic release of the cooling liquid, so as to achieve the purpose of rapid cooling and molding of the blown plastic. The overall use effect of the plastic device.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to a blow molding device for producing plastic packaging bags. Background technique [0002] Plastic is a common material. Plastic is generally a polymer compound that is polymerized by addition polymerization or polycondensation reaction using monomer as raw material. The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. , Plastic is widely used in various fields due to its low price, and there are many plastic products, such as plastic bags, plastic bottles, etc. There are many processing steps in the production of plastic packaging bags, among which the blow molding process is one of the most important steps. [0003] Chinese patent discloses (CN103737898A) a plastic bag forming device, including a mixer, the mixer is connected to a suction machine through a material tube, the material su...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that today’s plastic packaging bag blow molding device is not equipped with an automatically controllable cooling mechanism, and in the process of plastic bag blow molding, it is impossible to quickly form the blown material. As a result, the overall work efficiency is reduced, human control is required at the same time, and the use effect is not good. A blow molding device for plastic packaging bag production is proposed.
