[0029] Example:

[0030] A shredding device for recycling scrap metals comprises a carrying plate 1 and a supporting frame 2, wherein the supporting frame 2 is arranged on the bottom surface of the carrying plate 1, and a shredding component 5 and a control component 4 are arranged on the top surface of the carrying plate 1, and a driving component 3 is rotatably connected to both ends of the shredding component 5, and an adsorption screening component for screening scrap metals and scrap plastics is also arranged on the bottom surface of the carrying plate 1 corresponding to the shredding component 5, and the adsorption screening component is electrically connected to the control component 4.

[0031] It is explained that in order to facilitate the operator to put in the scrap metal materials to be shredded, a support frame 2 is set on the bottom of the supporting plate 1 to raise the height of the overall shredding device. In view of the fact that the materials to be processed contain metal materials, in order to ensure effective crushing and improve the quality of subsequent processing, the shredding device adopts a dual-drive design. This setting method can not only ensure the crushing effect of the metal materials, but also ensure the stable operation of the shredding component 5 and extend its service life.

[0032] Combined with the accompanying drawings Figure 1-Figure 5 The adsorption and screening component includes a separation component 7 and a pair of electromagnets 8, wherein the two electromagnets 8 are respectively arranged at two ends of the separation component 7, and the control component 4 is electrically connected to the two electromagnets 8 through a wiring harness.

[0033] It is explained that the electromagnet is electrically connected to the control component 4, so that the control component 4 can automatically adjust the power-on cycle of the electromagnet 8, effectively replacing manual operation. Thereby, precise control of the working state of the electromagnet 8 is achieved. This design not only improves work efficiency, but also reduces the difficulty of operation, making the application of the electromagnet 8 more extensive and convenient. At the same time, through automatic control, it can also effectively reduce the errors caused by human factors and improve the accuracy and stability of the overall work.

[0034] Combined with the accompanying drawings Figure 1-Figure 5The separation component 7 includes a first separation bucket 71 and a second separation bucket 74. The first separation bucket 71 is arranged on the bottom surface of the carrying plate 1, and the second separation bucket 74 is connected to the bottom surface of the first separation bucket 71. A plurality of connecting columns 73 are arranged on the top surface of the first separation degree, and the bottom surface of the connecting column 73 is connected to a guide plate 72. The electromagnet 8 is fixed on the side wall surface of the second separation bucket 74. The shredding component 5 includes an outer shell 51, a first rotating shaft 52 and a second rotating shaft 53. The two ends of the long side of the outer shell 51 are provided with bearing seats 56. The first rotating shaft 52 and the second rotating shaft 53 are rotatably connected to the outer shell 51. Between the bearing seats 56, the first rotating shaft 52 and the second rotating shaft 53 are respectively provided with first cutting teeth 54 and second cutting teeth 55 in a row, and the first rotating shaft 52 and the second rotating shaft 53 rotate in opposite directions, and the driving component 3 includes a first driving motor 31 and a second driving motor 32, the driving shaft of the first driving motor 31 is rotationally connected to the first rotating shaft 52, the driving shaft of the second driving motor 32 is rotationally connected to the second rotating shaft 53, and an end cover 57 is also connected to the bearing seat 56 on the side of the first rotating shaft 52 and the second rotating shaft 53 away from the driving component 3.

[0035] It is worth noting that the above structure can better separate the mixed waste plastics and crushed metals. We install an electromagnet 8 on the side of the second separation bucket 74. When the waste plastics and crushed metals are crushed and guided by the guide plate 72, and slide down along the inner wall of the second separation bucket 74, the electromagnet 8 will play a role and absorb the crushed metal materials. After all the waste plastics fall completely, the electromagnet 8 is demagnetized by operating the control component, so that the absorbed metal fragments fall off, and the two are effectively separated.

[0036] Combined with the accompanying drawings Figure 1-Figure 5 The connection between the driving shaft of the first driving motor 31 and the first rotating shaft 52 and the connection between the driving shaft of the second driving motor 32 and the second rotating shaft 53 are both connected through a coupling 9. A feed hopper 6 is also provided on the top surface of the shredding component 5. The upper opening of the feed hopper 6 is larger than the lower opening. The connection through the coupling 9 can better enable the two driving components 3 to respectively drive the first rotating shaft 52 and the second rotating shaft 53 to rotate in opposite directions, and cooperate with the first shredding teeth 54 and the second shredding teeth 55 to accurately cut the metal material. The device can not only ensure the efficient crushing of metal materials, but also ensure the stable operation of the shredding component 5, thereby significantly extending its service life.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
