However, my country's natural rubber resources are extremely scarce, and about 70% of the annual demand is met by imports. In order to reduce the pressure on the demand for rubber resources and maximize the effectiveness of the use of waste tires, my country and even the world usually adopt the practice of "refurbishing first, then scrapping".

[0003] The prior art (patent number: CN115635381A) discloses a tread grinding device for automobile tires, including a stand, an electrical control system is arranged in the stand, a sealing cover hinged to the upper surface of the stand is arranged, a pair of cylinders are hinged between the sealing cover and the stand, a lifting mechanism penetrating the sealing cover is arranged on the upper surface of the stand, a tread conveying mechanism penetrating the sealing cover is arranged on the lifting mechanism, a grinding mechanism located in the sealing cover is also arranged on the lifting mechanism, and the electrical control system connects and coordinates the control of the cylinder, the lifting mechanism, the tread conveying mechanism and the grinding mechanism. The beneficial effects of the utility model are: it is suitable for the soft tread grinding work of automobile tires, the mutual cooperation of the lifting mechanism and the tread conveying mechanism has automatic feeding and paving functions for soft treads of various thicknesses, thereby improving the grinding quality and greatly reducing manual participation, saving time and labor, being safe and reliable, and effectively improving the grinding efficiency of the soft tread; in addition, the grinding section is composed of two grinding processes, and the width of the cylindrical grinding roller and the wire grinding wheel can be appropriately adjusted according to the width of the soft tread to meet the grinding work of treads of various widths; and the grinding section is in a relatively closed environment, which effectively reduces the splashing of grinding waste and the impact on the environment, and can be directly connected to external dust removal and environmental protection equipment; and an atomization pipe is arranged in the closed environment, which not only reduces dust and suppresses dust, but also has the effect of cooling and preventing gelling.

[0004] The existing automobile tire tread grinding equipment has the following disadvantages. Since the existing equipment needs to be cleaned by staff for the debris generated by the tread grinding, but the debris cleaning effect is general, the equipment has certain limitations. Since the degree of tread wear is different, and the grinding depth of the equipment is not easy to adjust, the grinding effect of the tread is affected. Therefore, we propose a new type of automobile tire tread grinding equipment. Utility Model Content
