[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] A copper and aluminum stripping waste shredder, Figure 1 and Figure 2 As shown, it includes a frame 1 and a mincing bin 2 arranged on the frame 1. The mincing bin 2 is square in shape and has an upper bin opening and a lower bin opening that pass through. A rotating shaft 3 is rotatably installed in the mincing bin 2. The axial direction of the rotating shaft 3 is arranged along the length direction of the mincing bin 2, that is, bearing seats are provided at both ends of the mincing bin 2, and both ends of the rotating shaft 3 are installed in the bearing seats to realize the rotatable installation of the rotating shaft 3. A driving motor 4 is provided on the frame 1, and the output shaft of the driving motor 4 is connected to the rotating shaft 3 through a coupling. The rotating shaft 3 can be rotated in the mincing bin 2 by the driving motor 4.

[0025] At least one mincing knife 5 is installed on the rotating shaft 3, and a mounting shaft hole 6 is provided in the middle of the mincing knife 5. The mincing knife 5 is sleeved on the rotating shaft 3 through the mounting shaft hole 6. When multiple mincing knives 5 are installed on the rotating shaft 3, both ends of the rotating shaft 3 are threadedly connected with locking nuts 7 for abutting against the surface of the mincing knife 5. The locking nuts 7 are tightened against the surface of the mincing knife 5, so that multiple mincing knives 5 are stacked on the rotating shaft 3.

[0026] Reference Figure 3 and Figure 4 As shown, the mincing knife 5 is provided with at least one blade 51 in its circumferential direction. This embodiment is described by taking the mincing knife 5 as an example. The mincing knife 5 is provided with two blades 51 so that the mincing knife 5 is arranged in a diamond shape as a whole.

[0027] The blades 51 of adjacent mincing knives 5 are staggered in the circumferential direction. In one embodiment, the staggered angle of the blades 51 of adjacent mincing knives 5 in the circumferential direction is 45°; in another embodiment, the staggered angle of the blades 51 of adjacent mincing knives 5 in the circumferential direction is 60°; in another embodiment, the staggered angle of the blades 51 of adjacent mincing knives 5 in the circumferential direction is 90°. The staggered angle of the blades 51 of adjacent mincing knives 5 is not limited to the above angles and can be set according to actual needs.

[0028] The structure in which the blades 51 of adjacent mincing knives 5 are arranged staggered in the circumferential direction will be described below.

[0029] In this embodiment, the mounting shaft hole 6 in the center of the mincing blade 5 is polygonal in shape, and the rotating shaft 3 is provided with a mounting shaft segment that mates with the mounting shaft hole 6. The cross-section of the mounting shaft segment has the same shape as the mounting shaft hole 6. In one embodiment, the mounting shaft hole 6 is square in shape, and the cross-section of the mounting shaft segment is square; in another embodiment, the mounting shaft hole 6 is hexagonal in shape, and the cross-section of the mounting shaft segment is hexagonal; in another embodiment, the mounting shaft hole 6 is octagonal in shape, and the cross-section of the mounting shaft segment is octagonal.

[0030] By sleeve-mounting the mincing knives 5 onto the mounting shaft section and varying the sleeve-mounting angle of adjacent mincing knives 5 on the mounting shaft section, the blades 51 of adjacent mincing knives 5 can be staggered in the circumferential direction. Specifically, when the blades 51 of adjacent mincing knives 5 are staggered by 90°, the mounting shaft section and mounting shaft hole 6 need to be square. When the blades 51 of adjacent mincing knives 5 are staggered by 60°, the mounting shaft section and mounting shaft hole 6 need to be hexagonal. When the blades 51 of adjacent mincing knives 5 are staggered by 45°, the mounting shaft section and mounting shaft hole 6 need to be octagonal.

[0031] It is worth noting that the mincing knife 5 is composed of several blades of the same specification and shape stacked together. The mincing knife 5 is made of steel with a hardness of 45 or above. The length of the mincing knife 5 is 150mm-400mm, and the thickness of the mincing knife 5 is 3mm-300mm. Therefore, the thickness of the mincing knife 5 can be adjusted according to the number of stacked blades, and this embodiment does not make specific limitations.

[0032] Reference Figure 1 、 Figure 2 and Figure 3 As shown, a filter screen 8 is provided at the bottom of the mincing bin 2, and filter holes are distributed in an array on the filter screen 8. The radius of the filter holes is 75mm-210mm. Since the mincing knife 5 is driven by the rotating shaft 3 to rotate circumferentially, the shape of the filter screen 8 is adapted to the rotation arc of the mincing knife 5 to be arranged in a semicircular shape, wherein a mincing gap is formed between the mincing knife 5 and the filter screen 8, specifically, a mincing gap is formed between the blade 51 of the mincing knife 5 and the inner surface of the filter screen 8, and the mincing gap is 2mm-4mm.

[0033] Thus, the strip-shaped waste after the copper rod is drawn is put into the shredding bin 2, and the driving motor 4 drives the rotating shaft 3 to rotate. The driving motor 4 rotates at a speed of 30r / min-300r / min, and the shredding knife 5 rotates synchronously with the rotating shaft 3. A shredding gap is formed between the shredding knife 5 and the filter 8. The strip-shaped waste is brought into the shredding gap and shredded by the shredding knife 5. The long strip waste will be shredded into short strip waste until the waste is smaller than the diameter of the filter 8 on the filter 8. The waste will fall from the filter 8 and be recovered. The above method can be used to achieve the shredding of the waste to improve the smelting efficiency of the subsequent production of the waste. The copper and aluminum stripping waste shredder equipment of this application has a simple structure and high shredding efficiency.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
