[0002] Sponge is a porous material, which is usually made of synthetic materials such as polyurethane, polyether, polyester, polypropylene, etc. In our daily life, sponge is widely used, including household cleaning, beauty makeup, car washing, art, medical treatment and other fields. Sponges are divided into chemical sponges and industrial sponges according to the material. Chemical sponges are polyurethane soft foam rubber. Polyurethane is the most common polymer material in life, so chemical sponges are also called polymer sponges. In the process of processing polymer sponges, it is necessary to mix the foaming agent, auxiliary agent and base material together and foam them. A foaming device is needed for foaming. The sponge foaming device in the prior art is generally a foaming machine.

[0003] A sponge production foaming machine is disclosed in the patent document with publication number CN220409276U. The sponge production foaming machine can transport air to the inside of the annular tube through a hose when the air pump of the sponge production foaming machine is started. The air inside the annular tube can be discharged through the air outlet holes. By lifting the annular tube, the air can be evenly discharged into the foaming agent solution inside the cylinder through the air outlet holes on the inner side of the annular tube, thereby making the air diffusion more uniform and greatly improving the foaming effect. However, the threaded rods and other components required for controlling the lifting of the annular tube are installed inside the cylinder. In the process of producing sponges, raw materials are easy to adhere to the threaded rods, so that the threaded rods need to be cleaned each time after processing.
