The surface of the roller 22 is provided with a spiral guide plate 23;

[0027] Further, the two ends of the melting box 3 are fixedly connected with side plates 13, the surface of the side plate 13 is penetrated with a roller shaft 12, the bottom of the roller shaft 12 is installed with a fan blade 5, the top of the roller shaft 12 is sleeved with a sprocket 11, the surface of the sprocket 11 is transmission-connected with a chain 10, and the chain 10 is transmission-connected with a sprocket 16 sleeved on the surface of the roller shaft 7;

[0028] A melting box 3 is arranged on the top of the back plate 2 to melt the plastic particles. The motor 9 on the top of the melting box 3 drives the roller 7, the roller 22 and the guide plate 23 to rotate, so as to drive the molten plastic to move and accelerate the melting speed of the plastic particles. When the motor 9 drives the roller 7 to rotate, the sprocket 6 on the surface of the roller 7 is also driven to rotate. The sprocket 6 drives the sprocket 2 11 on both sides of the melting box 3 to rotate through the chain 10. The sprocket 2 11 drives the roller 2 12 and the fan blade 5 to rotate, so as to blow air toward the bottom of the melting box 3 and accelerate the air flow under the melting box 3.

[0029] On the basis of the above scheme, the cooling assembly includes a circulation pipe 14, a semiconductor cooling sheet 15 and a water tank 17. Two crossed circulation pipes 14 are inserted into the roller 4. A water tank 17 is installed at the other end of the roller 4.
