The heating rod 5 is activated to heat the raw material through the processing tank 1 to assist the reaction. The drive assembly is activated to drive the mixing and cleaning mechanism to rotate, thus mixing the adhesive raw material. Simultaneously, the vortex mixer 7 rotates to lift the raw material that has settled to the bottom. Opening the inlet / outlet assembly discharges the adhesive.
