The fourth gear 711 is fixedly connected to the second rotating rod 703 .

[0048] When the second motor 709 rotates, the second motor 709 drives the third gear 710 to rotate, and the third gear 710 rotates and drives the second rotating rod 703, and the second rotating rod 703 rotates and drives the second bevel gear 706 and the first gear 707 to rotate, and the second bevel gear 706 rotates and drives the first bevel gear 705 to rotate, thereby driving the first rotating rod 306 to rotate. When the temperature in the mixing box reaches a certain temperature, the second piston 605 will push the second rotating rod 703 to move right, and the second rotating rod 703 moves rightward and drives the second bevel gear 706 and the third gear 710 to move rightward. When the second bevel gear 706 moves to the right, the second bevel gear 706 separates from the first bevel gear 705, and the first rotating rod 306 stops rotating. When the third gear 710 moves to the right, until the third gear 710 is meshed with the fourth gear 711. After the third gear 710 is meshed with the fourth gear 711, the third gear 710 rotates and drives the fourth gear 711 to rotate, thereby driving the screw 502 to rotate.

[0049] Working principle: When it is necessary to mold the plastic, the staff opens the sealing cover 304 and pours the raw material from the feed pipe 303 into the mixing drum 302. After that, the staff turns on the electric heating wire 305 and the second motor 709, and the electric heating wire 305 heats and melts the raw material. When the staff turns on the second motor 709, the second motor 709 drives the third gear 710 to rotate, and the rotation of the third gear 710 drives the second rotating rod 703, and the rotation of the second rotating rod 703 drives the second bevel gear 706 and the first gear 707 to rotate. When the second bevel gear 706 rotates, the rotation of the second bevel gear 706 drives the first bevel gear 705 to rotate, and the rotation of the first bevel gear 705 drives the first rotating rod 306 to rotate, and the rotation of the first rotating rod 306 drives the fixed rod 307 and the first curved rod 401 to rotate, and the rotation of the fixed rod 307 drives the stirring rod 308 to rotate, and the stirring rod 308 rotates to stir the raw material to accelerate melting.

[0050] When the first curved rod 401 rotates, the rotation of the first curved rod 401 drives the second curved rod 402 to rotate, and the rotation of the second curved rod 402 drives the push rod 405 to move left and right, and the left and right movement of the push rod 405 drives the first piston 404 to move left and right. The left and right movement of the first piston 404 sucks the harmful gas generated after the raw materials are melted from the mixing drum 302 into the first sealing drum 403, and then the harmful gas is pushed into the purification box 407 by the piston, and the purification liquid 412 reacts with the harmful gas to achieve absorption of the harmful gas.

[0051] When the temperature in the mixing drum 302 rises, the heat in the mixing drum 302 will enter the insulation box 601 through the heat conducting rod 602, and the filling gas 610 in the insulation box 601 will absorb the heat and increase in volume. When the temperature in the mixing box rises to a certain temperature, the filling gas 610 will push the third piston 608 to move downward and push the second piston 605 to move to the right. When the third piston 608 moves downward, the third piston 608 opens the pressing switch 609, and the pressing switch 609 opens the first motor 507 and the electric valve 504, and the first motor 507 rotates, and the rotation of the first motor 507 drives the cutting blade 508 to rotate. When the pressing switch 609 opens the electric valve 504, the raw materials in the mixing drum 302 enter the barrel 501 from the hopper 503.

[0052] The second piston 605 moves rightward and drives the second rotating rod 703 to move rightward. The second rotating rod 703 moves rightward and drives the second bevel gear 706 and the third gear 710 to move rightward. When the second bevel gear 706 moves rightward, the second bevel gear 706 separates from the first bevel gear 705, and the first rotating rod 306 stops rotating. When the third gear 710 moves rightward, until the third gear 710 is meshed with the fourth gear 711. After the third gear 710 is meshed with the fourth gear 711, the third gear 710 rotates and drives the fourth gear 711 to rotate. The fourth gear 711 rotates and drives the screw 502 to rotate. The screw 502 rotates to squeeze the raw material in the barrel 501 into the discharge pipe 505. Then, the raw material enters the mold 506 through the discharge pipe 505 and is extruded into a long strip. After the raw material comes out of the mold 506, the cutting blade 508 cuts the long strip raw material into plastic particles.
