[0032] Specifically, in operation, first, the relevant feeding device 6 transmits the cable material particles from the inlet 133 to the first cavity 131, and makes the cable material particles on the screen 3, then, the vibration motor 2 is started, the vibration motor 2 drives the rack 1 and the screen 3 in turn to vibrate, so that the cable material particles move on the screen 3, then, the air flow supply unit is started, the air flow supply unit transmits air flow to the duct unit 42, and sprays to the screen 3 and the cable material particles through a plurality of injection ports 4221, which is convenient for preventing the cable material particles from adhering, and also convenient for cleaning the cable material particles in the mesh holes of the screen 3, so as to ensure the high screening efficiency of the cable material particles, finally, the cable material particles with particle size smaller than the mesh hole diameter of the screen 3 enter the second cavity 132 and are discharged from the second outlet 135, and the cable material particles with particle size greater than the mesh hole diameter of the screen 3 are discharged from the first outlet 134 of the first cavity 131, so as to complete the screening of the cable material particles.

[0033] The vibration motor 2 is used to drive the rack 1 and the screen 3 in turn to vibrate, and the vibration motor 2 can be YZU vibration motor, YZO vibration motor, etc., the power of the vibration motor 2 is preferably 3kW, and the frequency is preferably 1500 times / minute; the screen 3 is used for screening, since the height of the screen 3 gradually decreases along the direction from the inlet 133 to the first outlet 134, it is convenient to make the cable material particles on the screen 3 move from the inlet 133 to the first outlet 134 under the action of the vibration motor 2, and the material of the screen 3 is preferably stainless steel; the air flow supply unit is used to supply air flow to the duct unit 42, and the air flow supply unit can be an air pump, etc., the duct unit 42 sprays air flow to the screen 3 and the cable material particles through a plurality of injection ports 4221, which is convenient for preventing the cable material particles from adhering, and also convenient for cleaning the cable material particles in the mesh holes of the screen 3, so as to ensure the high screening efficiency of the cable material particles, and the air flow auxiliary cleaning assembly 4 composed of the air flow supply unit, the duct unit 42, etc. is adopted in the embodiment, which is not affected by the characteristics of the cable material particles during cleaning, has good cleaning stability, and the air flow will not accelerate the wear of the screen 3, and the cleaning efficiency is high, wherein the strength of the air flow supplied by the air flow supply unit is preferably 2.5bar.

[0034] Further, as Figure 2The duct unit 42 includes: an arc-shaped pipe 421 connected to the airflow supply unit; and a distribution pipe 422 connected to the frame 1, with one end of the distribution pipe 422 connected to one end of the arc-shaped pipe 421 and the other end of the distribution pipe 422 connected to the other end of the arc-shaped pipe 421. Several injection ports 4221 are disposed on the distribution pipe 422. Specifically, the airflow supply unit sequentially transmits airflow to the arc-shaped pipe 421 and the distribution pipe 422. The arc-shaped pipe 421 facilitates smooth airflow transition, thereby reducing airflow resistance. Since one end of the distribution pipe 422 is connected to one end of the arc-shaped pipe 421 and the other end of the distribution pipe 422 is connected to the other end of the arc-shaped pipe 421, the airflow within the arc-shaped pipe 421 is uniformly transmitted to the distribution pipe 422, thereby increasing the uniformity of airflow distribution within the distribution pipe 422.

[0035] Furthermore, such as Figure 2 The arc-shaped pipe 421 includes a first pipe body 4211 and a second pipe body 4212. One end of the first pipe body 4211, one end of the second pipe body 4212, and the airflow supply unit are connected by a three-way conduit 43. The other end of the first pipe body 4211 is connected to one end of the distribution pipe 422, and the other end of the second pipe body 4212 is connected to the other end of the distribution pipe 422.

[0036] Furthermore, such as Figure 2 The first tube 4211 and the second tube 4212 are symmetrically distributed about the three-way conduit 43. Specifically, the symmetrical distribution means that the three-way conduit 43 is located in the middle of the arc-shaped tube 421, which further facilitates the airflow supply unit to evenly transmit airflow to the first tube 4211 and the second tube 4212.

[0037] Furthermore, such as Figures 1-2 It also includes a support rod 5 connected to the frame 1, and a distribution pipe 422 connected to the support rod 5.

Figure 1 Specifically, since the size of the second cavity 132 gradually decreases, the cable material particles in the second cavity 132 are gathered to the second outlet 135, so that the cable material particles are discharged.

[0041] Further, as shown in Fig. 1, the second cavity 132 is provided with a first outlet 134 and a second outlet 135. Figure 1 The screen 3 comprises a first net body 31 and a second net body 32 connected with each other, the mesh diameter of the first net body 31 is smaller than that of the second net body 32, and the first net body 31 and the second net body 32 are connected with the rack 1.

[0042] The second cavity 132 is provided with a partition plate, so that the second cavity 132 is divided into a first collecting cavity 1321 and a second collecting cavity 1322, the first collecting cavity 1321 is arranged corresponding to the first net body 31, the second collecting cavity 1322 is arranged corresponding to the second net body 32, and the second outlet 135 is communicated with the second collecting cavity 1322.

[0043] Specifically, in the working process, the cable material particles with the smallest particle size enter the first collecting cavity 1321 through the first net body 31, the cable material particles with the medium particle size enter the second collecting cavity 1322 through the second net body 32 and are discharged from the second outlet 135, and the cable material particles with the largest particle size are discharged from the first outlet 134.

[0044] Further, as shown in Fig. 1, the second cavity 132 is provided with a first outlet 134 and a second outlet 135. Figure 1 The connection mode between the first net body 31 and the second net body 32 is integrally connected or welded.
