[0002] The full name of polyurethane foaming agent is single-component polyurethane foam sealant, commonly known as foaming agent, foam glue, PU sealant, and PU FOAM in English. It is the product of the cross-combination of aerosol technology and polyurethane foam technology. It is a special polyurethane product that fills components such as polyurethane prepolymer, foaming agent, and catalyst into a pressure-resistant aerosol can. When the material is sprayed out of the aerosol can, the foamy polyurethane material will expand rapidly and react with the air or moisture in the contacted substrate to form foam. In the process of using the polyurethane foaming agent, in order to facilitate the spraying of the workpiece, a spraying device will be used. The use of the spraying device can realize the automatic spraying of the polyurethane foaming agent on the workpiece;

[0006] 2. In the above-mentioned foaming agent spraying device, the lower combined mold frame is installed on the lower inner side of the U-shaped fixed plate through an electric turntable seat, and the upper combined mold frame is movably installed on the upper inner side of the U-shaped fixed plate through a hydraulic adjustment rod. The workpiece is fixed by the lower combined mold frame and the upper combined mold frame, but there is a lack of structure for cleaning the surface of the workpiece. The spraying of the polyurethane foaming agent may be affected due to dust on the surface of the workpiece. At the same time, it is not convenient to humidify the surface of the workpiece and it is not convenient to cure the polyurethane foaming agent. Utility Model Content
