After the quantitative weighing is completed, the solenoid valve is opened to add the raw materials and auxiliary materials into the mixing hopper, thereby realizing the quantitative addition capability of the equipment, reducing the labor intensity required for the operator during the weighing process, and improving the practicality of the device.

[0011] Preferably, the device also includes a heat exchange tube and a discharge valve. A heat exchange tube is wound around the side between the support chamber and the mixing chamber, and a discharge valve is installed at the output end of the mixing chamber. By introducing heat exchange liquid into the heat exchange tube, the material in the mixing chamber is heated and melted. In conjunction with the mixing device, multiple materials are mixed.
