Description

A hot air recyclable blister forming device

technical field

The invention relates to the technical field of machinery, in particular to a hot air recyclable blister forming device.

Background technique

Blister molding technology, that is, plastic plate thermoforming processing technology, is one of the plastic secondary processing industrial technologies. It is different from injection molding, extrusion and other one-time processing technology. It is not for heating molding of plastic resin or particles or continuous molding with the same cross-section of the die; nor is it using machine tools, knives and other machinery to cut a part of the plastic material. Next, get the required shape and size, but for the plastic plate, heat it, use the mold, vacuum or pressure to deform the plate to achieve the required shape and size, supplemented by supporting procedures to achieve the application purpose. During the plastic forming process, the plastic plate needs to be heated, and the plastic plate will produce harmful gas during the heating process, which will cause injury to the staff. Most of the existing blister forming devices filter the harmful gas generated in the device and directly discharge it into the atmosphere, but this will cause waste of hot air. For this reason, we propose a kind of hot air recyclable blister forming device.
