Description

Technical Field

[0001] The present application relates to a tire grinding device for new energy vehicles, belonging to the technical field of tire processing. Background Art

[0002] Tires are circular, elastic rubber products that roll against the ground and are installed on various vehicles and machinery. Typically mounted on metal rims, tires support the vehicle's body, cushion external impacts, maintain contact with the road, and ensure vehicle performance.

[0003] With the gradual implementation of the "dual carbon" goals and the increasing awareness of environmental protection, the number of new energy vehicles on the road is steadily increasing. Consequently, the number of scrap tires from new energy vehicles has also increased dramatically, leading to a series of problems such as resource waste and environmental pollution caused by the disposal of these scrapped tires. The severe shortage of natural and synthetic rubber resources has also driven the rapid development of the tire retreading industry. Tire retreading involves recycling worn, unusable tires by grinding and re-vulcanizing them, significantly conserving rubber materials and protecting the environment. The tire retreading process begins with grinding the tire surface. Traditional grinding processes require manual tire rolling, which is laborious and time-consuming. Manual tire grinding typically involves a simple fixing method, which can lead to instability during handling, compromising the handling efficiency. Furthermore, to meet the requirements of new energy vehicles, tires typically feature a variety of tread patterns on the crown, shoulder, and sidewalls to achieve low rolling resistance, low noise, and high grip.

[0004] Chinese patent CN203542268U discloses a tire retreading and grinding machine that can process different types of tires. However, it only grinds the crown portion and cannot grind the shoulder and sidewall portions. In addition, frictional heat is generated during the grinding process, which causes the temperature of the tire to rise, easily damaging the inner wall of the tire and affecting the grinding effect.
