[0020] The crushing assembly 10 includes a rotating shaft and a cutting blade. The cutting blade is arranged around the outer surface of the rotating shaft. The rotating shaft drives the cutting blade to rotate, thereby cutting the injection molding waste.

[0021] A first feed port 101 is formed at the upper end of the pulverizing assembly 10 ; a first discharge port 201 is formed at the lower end of the pulverizing assembly 10 .

[0022] The swing screen device is arranged at the lower side of the bracket 5. The swing screen device comprises a swing screen body 6, a second feed port 102, a second discharge port 202, a third discharge port 203 and a base 7. The swing screen body 6 is connected to the upper side of the base 7 through a torsion spring. By setting the connection of the torsion spring, the stability of the swing screen during operation is ensured.

[0023] The second feed port 102 is provided at the upper end of the swing screen body 6. The crushing box is connected to the swing screen device through a first conduit 301. The two ends of the first conduit 301 are respectively connected to the lower end of the first discharge port 201 and the upper end of the second feed port 102. The swing screen body 6 is an existing device, and its specific structure is common knowledge to those skilled in the art, and will not be described in detail here.

[0024] The second discharge port 202 and the third discharge port 203 are arranged on the outer surface of the side wall of the swing screen body 6. The lower end of the second discharge port 202 is connected to the second conduit 302 and is connected to the upper end of the second conduit 302. The lower end of the third discharge port 203 is connected to the third conduit 303 and is connected to the upper end of the third conduit 303. The lower end of the second conduit 302 is connected to the fourth conduit 304. The lower end of the third conduit 303 is connected to the fifth conduit 305.

[0025] The fourth conduit 304 and the fifth conduit 305 are both provided with lower ports. The lower ports of the fourth conduit 304 and the fifth conduit 305 are both connected with a fan 8 at their end faces and are sleeved on the air outlet of the fan 8. The crushed plastic waste is screened by the swing screen device and then enters the conduit, and is transported by the wind of the fan 8 to the next device.

[0026] The fan 8 is provided with a first air outlet and a second air outlet; the first air outlet and the second air outlet are arranged adjacent to each other; the lower end of the fourth conduit 304 is sleeved on the end face of the first air outlet; the lower end of the fifth conduit 305 is sleeved on the end face of the second air outlet. When the fan 8 is used to transport the same items, the weight of the items is not much different, and the required wind force is almost the same. The same fan 8 can be used to transport at the same time by setting different air outlets, saving resources.

[0027] The upper end of the fourth conduit 304 is connected to the first feed port 101, and the upper end of the fifth conduit 305 is connected to the body of the injection molding machine 9. The body of the injection molding machine 9 is an existing device, and its specific structure is common knowledge to those skilled in the art, and will not be described in detail here.

[0028] Working principle: Injection molding waste enters the pulverizing device through the first feed port 101 for pulverization, enters the swing screen device through the second feed port 102, and is screened into large and small particles in the swing screen device. Large particles are discharged from the second discharge port 202, and small particles are discharged from the third discharge port 203. The second discharge port 202 and the third discharge port 203 are respectively connected to the second discharge conduit 302 and the third discharge conduit 303. The second conduit 302 and the third conduit 303 are respectively connected to the fourth conduit 304 and the fifth conduit 305. The lower end ports of the fourth conduit 304 and the fifth conduit 305 are provided with a fan 8. With the help of the wind power of the fan 8, the large particles and the small particles are transported to the next device. The large particles return to the first feed port 101 and enter the pulverizing box for secondary pulverization, and the small particles enter the injection molding machine 9 for injection molding.

[0029] Specific embodiment 2: The difference from specific embodiment 1 is that the lower end of the second conduit 302 is provided with a first storage box 401, and the lower end of the third conduit 303 is provided with a second storage box 402.
