[0020] Working principle: when the device is started, the motor 301 drives the reciprocating screw 403 to rotate through the belt 401, and drives the movable plate 410 to move forward and backward through the cross spiral groove on the reciprocating screw 403. The movable plate 410 moves forward and backward to drive the rotating rod 2 405 to move forward and backward. The rotating rod 2 405 moves forward and backward to drive the roller 1 404 to move forward and backward. When the roller 1 404 moves forward and backward, it contacts the slide plate 407 and rotates by friction. When the roller 1 404 rotates, it drives the rotating rod 2 405 to rotate. The rotation of the rotating rod 2 405 drives the cross stirring fan 1 406 to rotate to stir the falling melted plastic particles, ensuring that the plastic particles are evenly heated during the heating process, avoiding local overheating, thereby improving the melting efficiency, and at the same time, the slide plate is squeezed by the forward and backward movement of the roller 1 404. 407, so that the slide plate 407 moves up and down, the plastic particles are screened by the screen plate 409 to remove the dust and impurities in the plastic particles and enter the collecting box 408, so as to prevent the dust and impurities in the plastic particles from affecting the effect of the finished product after melting.

When the screen plate 409 swings downward, the plastic particles on the top thereof will slide down from both sides of the screen plate 409 and enter the bottom wall inside the melting kettle 402 for melting. When the screen plate 409 swings upward, the plastic particles on the top thereof will vibrate, so that the dust in the middle will be shaken off and pass through the screen plate 409, so that the dust enters the collecting box 408 for collection.

[0021] The upward and downward movement of the slide plate 407 drives the hinged rod 501 to move up and down, and the upward and downward movement of the hinged rod 501 drives the hinged plate 502 to move up and down, and the upward and downward movement of the hinged plate 502 drives the rotating rod three 504 to move up and down, and the upward and downward movement of the rotating rod three 504 drives the roller two 503 to move forward and backward, so that the roller two 503 moves forward and backward and rotates after contacting the inner wall of the melting kettle 402, and the rotation of the roller two 503 drives the rotating rod three 504 to rotate, and the rotation of the rotating rod three 504 drives the cross stirring fan two 505 to rotate, and the rotation of the cross stirring fan two 505 reduces the bubbles generated when the plastic particles are melted when the plastic particles are heated and melted, which affects the subsequent processing and production of the plastic pallet, and drives the cam two 506 to rotate through the rotation of the reciprocating screw rod 403.
