[0054] Furthermore, the slide rod 8 is fixed on both sides of the fixed tube 5; the slider 9 is slidably sleeved outside the slide rod 8; the spring 10 is sleeved outside the slide rod 8, and its two ends are fixedly connected to the slider 9 and the fixed tube 5; wherein the extrusion component 7 is fixedly connected to the slider 9.

[0055] Furthermore, the movable ring 11 has two ends fixedly connected to the slider 9 and a mounting groove 26 is provided on the top; the pressure plate 12 is rotatably mounted in the mounting groove 26; and the fixing rod 13 is fixedly connected to the top of the pressure plate 12.

[0056] Furthermore, a pair of through holes 24 are provided on both sides of the fixing tube 5 for slidably installing the slider 9 ; a pair of cavities 25 are provided in the fixing tube 5 for fixedly installing the slide bar 8 .

[0057] In this embodiment of the present application, due to the adoption of the above-mentioned structure, a spiral feed shaft is rotatably installed inside the extrusion barrel 1, and the raw material is placed in the extrusion barrel 1. The raw material is crushed and extruded by the rotation of the spiral feed shaft. The raw material is melted by the setting of the heating device in the extrusion barrel 1, and then the melted raw material is extruded through a number of output holes set at the end to form a shaped linear solid; after the linear solid is cooled by the cooling trough 2, it is conveyed to the slitting mechanism 3, and is cut by the slitting mechanism 3 to form plastic particles.

[0058] The fixed cylinder 5 is fixedly installed on the top of the extrusion cylinder 1 and is connected with the extrusion cylinder 1. Cavities 25 are arranged inside the two sides of the fixed cylinder 5. Through holes 24 are arranged on the sides of the cavity 25. The cavity 25 is connected with the interior of the fixed cylinder 5 through the arrangement of the through holes 24; the slide bar 8 is fixedly installed in the cavity 25, and a slider 9 is slidably installed on the slide bar 8. The side of the slider 9 movably passes through the through hole 24 and extends into the fixed cylinder 5. The spring 10 is sleeved on the outside of the slide bar 8, and the two ends are fixedly connected to the inner wall of the cavity 25 and the slider 9; the movable ring 11 is movably installed in the fixed cylinder 5, and a feeding hole is opened in the center of the movable ring 11. The two sides are fixedly connected to the slider 9, and the side of the movable ring 11 is in contact with the inner wall of the fixed cylinder 5; the top of the movable ring 11 is provided with a mounting groove 26, and a pressure plate 12 is installed in the mounting groove 26 so as to be openable and closable, and a fixed rod 13 is fixedly connected to the outer side of the pressure plate 12.

[0059] The raw material is loaded through the loading hole on the movable ring 11. When the raw material is blocked in the extrusion barrel 1, the pressing plate 12 is buckled in the mounting groove 26, and then the pressing plate 12 and the movable ring 11 are pressed downward by the fixed rod 13. The movable ring 11 slides in the fixed barrel 5, and at the same time drives the slider 9 to move downward along the slide rod 8 and squeezes the spring 10. The spring 10 is deformed. At the same time, due to the movement of the pressing plate 12 and the movable ring 11, the raw material blocked in the extrusion barrel 1 and the fixed barrel 5 is pushed downward, so that the blocked raw material can enter the working range of the spiral feed shaft in the extrusion barrel 1. Then the setting of the fixed rod 13 can be loosened, and the pressing plate 12 and the movable ring 11 can return to their original positions under the action of the spring 10. The raw material can be moved by moving the pressing plate 12 and the movable ring 11 downward again. Through the above operation, the raw material is prevented from being blocked in the extrusion barrel 1, affecting the normal operation of the extrusion barrel 1 and reducing the working efficiency of the extrusion barrel 1.

[0063] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the fixed frame 14 is fixedly arranged at the output end of the slitting mechanism 3, and an electric telescopic rod 17 is fixedly installed on one side of the inner wall of the fixed frame 14, and the output end of the electric telescopic rod 17 is fixedly connected to the mounting frame 16, and the other side of the mounting frame 16 is fixedly connected to the support rod 18, and the support rod 18 movably penetrates the fixed frame 14 for supporting the mounting frame 16; a plurality of positive and negative electrodes 15 are fixedly installed at the upper and lower ends of the mounting frame 16, and electric heating cutting wires 27 are fixedly installed between the positive and negative electrodes 15, and the electric heating cutting wires 27 are parallel to each other, and the positions of the plurality of electric heating cutting wires 27 and the plurality of linear solids are staggered.

[0064] When the formed linear solid is output from the output end of the slitting mechanism 3, the positive and negative electrodes 15 are started, and the positive and negative electrodes 15 can heat the electric heating cutting wire 27. Then the electric telescopic rod 17 is started, and the electric telescopic rod 17 drives the mounting frame 16 to move, and the mounting frame 16 drives the electric heating cutting wire 27 to move. At the same time, due to the movement of the electric heating cutting wire 27, the linear solid is cut to form plastic particles.

After being cooled and formed by the cooling trough 2, the linear solid will float in the cooling trough 2. The movable connecting block 20 slides in the slide 19. The connecting block 20 drives the mesh plate 21 to move. At the same time, the mesh plate 21 filters and collects the debris floating in the cooling trough 2. After the debris is gathered at one end of the cooling trough 2, the debris can be collected and processed through the through groove 23 and the collection frame 22 set at one end of the cooling trough 2.
