Through the action of the baffle 17, the EPS particles that fall onto the disc 16 can be driven to rotate, and through the action of centrifugal force, the EPS particles can be scattered outward, so that the EPS particles can be dispersed and fall into the inside of the foaming box, preventing the EPS particles from being concentrated and aggregated, which is conducive to the uniform and rapid heating of the EPS particles.

[0025] Furthermore, a conveying screw 19 is provided inside the feeding pipe 11, and a second motor 18 is fixedly installed on one side of the feeding box 3. The output end of the second motor 18 is fixedly connected to the conveying screw 19.
