Chemical material polyurethane foaming machine

Abstract

The inventing discloses a chemical material polyurethane foaming machine which comprises a foaming machine shell and a stirring mechanism fixedly mounted on the foaming machine shell for mixing a foaming agent. The foaming machine shell comprises a foaming barrel, a joint pipe penetrating into the foaming barrel vertically is arranged at the bottom of the foaming barrel, the stirring mechanism comprises a hollow stirring shaft penetrating into the foaming machine shell and a connecting sleeve rotatably connected to the lower end of the stirring shaft, the connecting sleeve is also connected to the upper end of the joint pipe, the joint pipe are connected to the stirring shaft, a plurality of connected ventilating branch pipes are distributed on the stirring shaft, and the foaming machine also comprises an inner supporting mechanism fixedly mounted on each ventilating branch pipe and a flexible glue air bag mounted on each inner supporting mechanism. The foaming machine integrates an air inlet mechanism and a stirring mechanism through a gas circuit design, so that the foaming efficiency and the effect and quality of forming a foaming material are improved greatly.

Description

technical field [0001] The invention relates to the technical field of polyurethane foaming machines, in particular to a chemical material polyurethane foaming machine. Background technique [0002] Polyurethane foaming machine is a special equipment for infusion and foaming of polyurethane foam. It is foamed by chemical reaction of polyether polyol and polyisocyanate in the presence of various chemical additives such as foaming agent, catalyst and emulsifier. Obtained foam. Polyurethane foaming machine can be used for automobile interior decoration, thermal insulation wall spraying, thermal insulation pipe manufacturing, and processing of bicycle and motorcycle seat sponges. [0003] In order to make polyether polyol and polyisocyanate fully mix and contact with various chemical additives such as foaming agent, catalyst, emulsifier and other chemical additives for chemical reaction foaming, the traditional polyurethane foaming machine is equipped with a stirring mechanism,...

AI Technical Summary

Problems solved by technology

[0003] In order to make polyether polyol and polyisocyanate fully mixed and contacted with various chemical additives such as foaming agent, catalyst, emulsifier, etc. for chemical reaction foaming, the traditional polyurethane foaming machine is equipped with a stirring mechanism and will be set separately The air intake mechanism blows air and foams, so that a bulky foam viscous liquid is formed under the blowing of gas. Generally, the air intake mechanism is mostly installed at the bottom of the foaming machine, and the stirring and air blowing are carried out independently. However, such a design There is a problem of uneven air blowing in the structure, which will affect the effect and quality of the foaming material produced by the mixing reaction of raw materials
