Description

Technical Field

[0001] The utility model relates to the technical field of tire vulcanizing equipment, in particular to a tire vulcanizing machine. Background Art

[0002] Vulcanization technology is widely used in industrial production. The overall hardness of certain materials (such as rubber) can be improved through vulcanization. Rubber is one of the main materials for manufacturing tires. The outer tire made of rubber is a viscoelastic plastic rubber before undergoing vulcanization. It is easy to deform and has low strength. After vulcanization, the rubber solidifies and has higher strength and elasticity.

[0003] Existing new energy energy-saving heating vulcanization equipment usually includes a heating device and a driving device (usually including a direct drive motor). The heating medium (usually nitrogen) is heated to a preset temperature by the heating device, and the heating medium is driven by the driving device to circulate inside or outside the vulcanization bladder to achieve heating and vulcanization of the tire. Compared with traditional vulcanization equipment, the driving device will be directly affected by the high-temperature and high-pressure heating medium, resulting in a reduced service life of the driving device.
