[0061] S1. Plastic crushing: Place the plastic in the second placement cylinder 103, and then turn on the crusher 104 to crush the plastic.

[0062] S2. Material transportation: Turn on the motor 207. The output end of the motor 207 drives the rotating rod 206 to rotate, thereby driving the stirring member 201 to move upward, causing the trigger block 203 to rise into the limiting groove 501, causing the moving block 502a to move horizontally, thereby driving the opening and closing plate 502d to open, causing the blanking groove 502f to open, and the internal plastic to fall into the cleaning cylinder 401.

[0063] S3. Device fixing: Turn on the motor 207.

[0065] S5. Screening of materials: The crushed plastic enters the storage tank 407a through the feed inlet 407c. Then, the motor 207 is turned on to drive the cleaning cylinder 401 to rotate. The second engaging plate 406d is driven to rotate through the first engaging plate 406a, driving the rotating ring 406c to rotate. Furthermore, the crushed plastic is moved by the second stirring rod 406e. The small plastics will fall through the discharge chute 502f to the next process. The plastics that have not been completely crushed can be taken out for re-crushing after opening the box door 407d after the screening is completed.

[0066] During use, the plastic is placed in the second placement cylinder 103. Then, the crusher 104 is turned on to crush the plastic. Subsequently, the motor 207 is turned on. The output end of the motor 207 drives the rotating rod 206 to rotate, thereby driving the stirrer 201a to move upward, causing the trigger block 203 to rise into the limit groove 501, enabling the moving block 502a to move horizontally, and then driving the opening and closing plate 502d to open, so that the discharge chute 502f is opened, and the internal plastic falls into the cleaning cylinder 401. The motor 207 is turned on in the reverse direction to drive the stirrer 201a to move downward through the rotating rod 206, causing the toothed plate 202 to drive the gear 304a to rotate. Then, the threaded rod 304c is driven to move through the sleeve 304b, causing the second fixing plate 304f to pop out to fix the cleaning cylinder 401. Water is placed in the first placement cylinder 101. Then, the water flows into the cleaning cylinder 401 through the first water inlet 303. The stirrer 201a is turned on to rotate, so that the first stirring rod 201b cleans the plastic. After the cleaning is completed, the motor 207 is turned on in the reverse direction to retract the second fixing plate 304f. Then, the cleaning cylinder 401 can be driven to move upward by the stirrer 201a and fixed to the fixed groove 404 through the clamping block 204c. The crushed plastic enters the storage tank 407a through the feed inlet 407c. Then, the motor 207 is turned on to drive the cleaning cylinder 401 to rotate, dehydrating the internal plastic. The water flows out through the water outlet pipe 302. Then, the second engaging plate 406d is driven to rotate through the first engaging plate 406a, driving the rotating ring 406c to rotate. Furthermore, the crushed plastic is moved by the second stirring rod 406e. The small plastics will fall through the discharge chute 502f to the next process. The plastics that have not been completely crushed can be taken out for re-crushing after opening the box door 407d after the screening is completed.

4. A crushing treatment device for automotive plastic parts according to claim 1, characterized in that: The toothed plate (202) meshes with the gear (304a), and the upper end of the return spring (304e) is fixedly connected to the second fixing plate (304f).

5. The crushing and processing device for automotive plastic parts according to claim 1, wherein: The trigger block (203) is in close contact with the inner wall of the limit groove (501). A movement groove is formed in the second placement cylinder (103), and the limit block (502e) is in close contact with the inner wall of the movement groove.

6. A method for crushing and processing automotive plastic parts, which is applied to the automotive plastic part crushing and processing device described in any one of claims 1-5, characterized in that It includes the following steps: S1. Plastic crushing: Place the plastic in the second placement cylinder (103), and then turn on the crusher (104) to crush the plastic. S2. Material transportation: Turn on the motor (207). The output end of the motor (207) drives the rotating rod (206) to rotate, thereby driving the stirring member (201) to move upward, causing the trigger block (203) to rise into the limit groove (501), enabling the moving block (502a) to move horizontally, and then driving the opening and closing plate (502d) to open, so that the material discharge groove (502f) opens, and the internal plastic falls into the cleaning cylinder (401). S3. Device fixation: Turn on the motor (207). The motor (207) drives the stirring member (201) to move downward through the rotating rod (206), causing the toothed plate (202) to drive the gear (304a) to rotate, and then driving the threaded rod (304c) to move through the sleeve (304b), so that the second fixing plate (304f) pops out to fix the cleaning cylinder (401). S4. Material cleaning: Turn on the motor (207) to drive the stirrer (201a) to rotate, so that the first stirring rod (201b) cleans the plastic. After the cleaning is completed, reverse the motor (207) to retract the second fixing plate (304f), and then the stirrer (201a) can drive the cleaning cylinder (401) to move upward. S5. Material screening: The crushed plastic enters the storage tank (407a) through the feed port (407c). Then turn on the motor (207) to drive the cleaning cylinder (401) to rotate, drive the second meshing plate (406d) to rotate through the first meshing plate (406a), drive the rotating ring (406c) to rotate, and then move the crushed plastic through the second stirring rod (406e). The small plastic will fall through the material discharge groove (502f) to the next process. The plastic that has not been completely crushed can be taken out for re-crushing after opening the box door (407d) after the screening is completed.
