Description
Technical Field

[0002] Foaming equipment is a device that can make foam from an aqueous solution of a certain concentration of foaming agent. The foaming agent itself cannot automatically become foam.

For example, a PU foam frame is a foaming machine that stirs water and a foaming agent at high speed to achieve uniform fusion and then sprays the mixture into a mold through a foaming gun. However, the stirring device of the existing foaming machine stirs the solvent using a main shaft and stirring blades, but the solvent often rotates in one direction in the tank body, so the contact area between water and the foaming agent is not large, resulting in an increase in stirring time and uneven and incomplete stirring.
