[0029] Through the function of the guide hopper 32, the polyurethane insulation board fragments filtered by the filter plate 31 can be transported to the inner cavity of the hot melt box 1 for melting treatment.

[0030] The cutting assembly 5 includes a fixed block 51, the outer wall of the fixed block 51 is fixedly connected to the top of the inner cavity of the cutting box 3, the inner cavity of the fixed block 51 is rotatably connected to two crushing rollers 52, the inner cavity of the fixed block 51 is fixedly connected to a triangular fixed block 53 and the triangular fixed block 53 is located below the two crushing rollers 52;

The crushed polyurethane insulation board fragments fall evenly between the stirring and grinding assembly 55 and the cutting box 3 under the action of the triangular fixing block 53, so as to facilitate uniform feeding.

[0032] A motor 54 is fixedly connected to the top of the inner cavity of the triangular fixed block 53, and a stirring and grinding assembly 55 is fixedly connected to the output end of the motor 54. The stirring and grinding assembly 55 is located between the fixed block 51 and the filter plate 31.
