8. The automatic brushing system according to claim 6, wherein said rotary drive member (54) is a rotary drive element such as a gear or sprocket.
9. An automatic brushing system according to claim 1, wherein said brush means (7) is U-shaped and has on its inside brushing bristles for brushing worn tyres.
10. An automatic brushing method for waste tires is characterized by comprising the following steps:
①, controlling the forward running of the waste tire conveying line (1) and the lifting device (2) to be at a low position, and conveying the waste tires to the lifting device (2) from the feeding hole;
② the tire center positioning device (21) on the lifting device (2) realizes the positioning of the waste tire, the center of the waste tire is positioned on the working track of the cantilever-type manipulator (3), then the cantilever-type manipulator (3) is controlled, and the expanding clamp (4) is positioned at the station of the lifting device;
③, controlling the lifting device (2) to move to a high position, enabling the grabbing part of the expanding clamp (4) to be located at the inner ring of the waste tire, and then grabbing the waste tire by using the expanding clamp (4);
④ controlling the lifting device (2) to be at a low position, and transferring the waste tires from the station of the lifting device to the brushing station by the rotary motion of the cantilever-type manipulator (3);
⑤ the waste tires rotate along the central axis under the action of the brushing rotary shaft (5) and the brushing drive motor (6), and the brushing of the waste tires is realized under the action of the brush device (7) and the brushing nozzle (8);
⑥, after the waste tires are scrubbed, controlling the cantilever type manipulator (3) to transfer the waste tires from the scrubbing station back to the position of the lifting device, and controlling the lifting device (2) to move to a high position;
⑦ when the lifting device (2) moves to the high position, the outward expansion type clamp (4) is controlled to release to grab the waste tire;
⑧ controlling the lifting device (2) to move to a low position to realize the separation of the waste tire and the external expansion type clamp (4);
⑨ controls the waste tyre conveying line (1) to run reversely to convey the waste tyres out of the brushing area.
The steps ① - ⑨ are repeated to achieve continuous automatic brushing of the junked tires.
