Description

Technical Field

[0001] This application relates to the field of hot plate vulcanizing machine technology for tires, specifically an external temperature control system for a hot plate vulcanizing machine for tires. Background Technology

[0002] Hot plate vulcanizing machines have seen rapid development due to their ability to independently control the temperature of the tire sidewall and tread, while also offering advantages such as saving significant amounts of steam and reducing equipment leakage points. During tire vulcanization, steam is introduced into the upper and lower hot plates, the mold sleeve chamber of the movable mold, and the bladder of the central mechanism to heat and vulcanize the tire blank. Uneven mold temperature can affect the vulcanization quality of the tire, making temperature monitoring crucial. Currently, external temperature control systems are used to regulate the temperature during vulcanization to ensure quality and effectiveness. These systems use temperature sensors to detect pipe temperatures and control the hot plate temperature, enabling precise temperature monitoring and adjustment to prevent quality issues caused by unstable or uneven temperatures. However, temperature sensors can malfunction or break down during vulcanization. Replacing the sensor would interrupt the vulcanization process, affecting tire quality and consistency. Therefore, stopping the machine to replace the sensor would reduce production efficiency and increase costs. Utility Model Content
