[0002] The foaming machine is a device for making foam from a water solution of foaming agent, which is indispensable in the production process of polyurethane foaming and other products. After completing injection molding, the mixing head gun nozzle of the foaming machine will have residual foaming material. If these residual materials are not cleaned in time, not only will it affect the precision and quality of the next injection molding, causing defects in the product, but also it may cause the gun nozzle to be blocked due to long-term accumulation, making the foaming machine unable to work normally.

[0003] The traditional method of cleaning the residual material of the mixing head gun nozzle is to use a blade or other tool to clean the foaming gun head manually, which is inconvenient and inefficient, and the cleaning effect may be affected by inconsistent operation of the cleaning personnel. In addition, when manually cleaning the gun head of different color foaming materials, product contamination may occur, even leading to product scrap. Moreover, manual cleaning usually requires the machine to be stopped, which will cause production to stop, increasing labor and time costs.

[0004] Currently, the common cleaning equipment is to drive the mixing head gun nozzle to move back and forth on the sponge layer to remove the residual material, or to use a brush to clean the residual material.
