Filter ports 2 are arranged on both sides in the length direction of the housing 1, and filter meshes are installed in the filter ports 2. Baffles 3 that block the filter ports 2 are arranged on both sides inside the housing 1. A frame body 14 is flatly arranged above the housing 1, a material storage shell 17 is arranged inside the frame body 14, the lower end of the material storage shell 17 shrinks inward and extends into the housing 1 to form a discharge port, and a driving mechanism for driving the material storage shell 17 to move back and forth is installed on the frame body 14.
[0024] In this embodiment, the driving mechanism includes a lead screw 16, a motor, and a bearing. A lead screw hole is horizontally provided on the material storage shell 17. The lead screw 16 is threadedly connected to the lead screw hole. The bearing is embedded in one end face of the frame 14. An axial hole communicating with the outside is provided at the other end of the frame 14. The motor is installed at one end of the frame 14. The rotating shaft of the motor passes through the axial hole and is fixedly connected to the lead screw 16 through a coupling. The other end of the lead screw 16 is fixedly connected to the inner ring of the bearing.
[0025] In this embodiment, a semiconductor refrigeration sheet 19 is installed on the bottom surface of the housing 1.
[0026] In this embodiment, the four edges of the rubber layer 11 are fixedly connected to the bottom surface inside the housing 1 through glue. A transverse opening is provided in the middle of the bottom surface of the housing 1. A push plate 18 is provided in the transverse opening. The top surface of the push plate 18 is in contact with the bottom surface of the rubber layer 11. A fixing frame is installed inside the air cavity. A first cylinder 20 is installed in the middle of the fixing frame. The piston rod of the first cylinder 20 is installed on the bottom surface of the push plate 18.
[0027] In this embodiment, fixing plates 4 are installed on the outer sides of the baffles 3. Positioning rods 5 are installed on the bottom surfaces of the fixing plates 4. Positioning holes are provided on the opening end surfaces of the housing 1 opposite to the positioning rods 5. The other ends of the positioning rods 5 are inserted into the positioning holes. The baffles can be limited by the positioning holes and the positioning rods, so that the baffles can only move up and down along the positioning holes, avoiding tilting.
[0028] In this embodiment, top plates 8 are installed on the outer sides of the baffles 3. Connecting plates 7 are installed on the sides of the housing 1 opposite to the top plates 8. Second cylinders 6 are installed on the connecting plates 7. The piston rods of the second cylinders 6 pass through the connecting plates 7 and are installed on the bottom surfaces of the top plates 8.
[0029] In this embodiment, an air inlet pipe 10 communicating with the air cavity is installed at one end of the bottom shell 9. An axial flow fan can be installed on the outer side end of the air inlet pipe.
[0030] In this embodiment, chutes 15 are provided on both sides inside the frame 14. Sliders are formed protruding from both sides of the material storage shell 17 opposite to the chutes 15. The sliders are slidably arranged in the chutes 15. The material storage shell can be positioned through the chutes and the sliders, so that the material storage shell can only move back and forth along the chutes.
[0031] In this embodiment, a plurality of support rods 13 are installed between the frame 14 and the housing 1. The frame can be fixed above the housing through the support rods.
[0032] During use, plastic particles can be directly poured into the material storage shell, and the motor is started. The start of the motor drives the lead screw.

[0033] After the above is completed, an axial flow fan can be installed on the intake pipe. The wind energy generated by the axial flow fan blows along the intake pipe into the air cavity until it is discharged from the air outlet holes. The gas discharged from the air outlet holes can blow on the plastic particles. During the blowing process, the semiconductor refrigerating sheet can be started. The cold air generated by the semiconductor refrigerating sheet can directly act on the housing, causing the housing to cool rapidly. The plastic housing is laid on the rubber layer of the housing, and the rubber layer is made of a high thermal conductivity rubber composite material, so it has good thermal conductivity, enabling the cold air on the housing to act on the rubber layer, and the cold air on the rubber layer can directly act on the plastic particles, causing the plastic particles to cool rapidly;
[0034] Among them, after the cooling is completed, the second cylinder can be started, causing the piston rod on the second cylinder to extend. The extended piston rod can push up the top plate. The movement of the top plate drives the baffle plate, causing it to rise stably along the positioning holes. After the baffle plate rises, the filter opening will be in an open state;
[0035] After the above is completed, the first cylinder can be started, causing the piston rod on the first cylinder to extend. The extended piston rod can push up the push plate. The rising push plate can arch the middle of the rubber layer, causing the plastic particles to slide toward both sides along the arched rubber layer until the plastic particles are discharged through the filter screen.
[0036] As described above, only the specific embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative labor should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
