Description

Technical Field

[0001] The utility model relates to the technical field of vulcanization devices, in particular to a compressed air heating type rubber belt vulcanization device. Background Art

[0002] The vulcanization of rubber is to convert the basically plastic raw rubber into elastic and dimensionally stable cooked rubber through the chemical cross-linking between rubber molecules. The physical properties of the vulcanized rubber are stable and its scope of use is expanded. The vulcanization of rubber belts is generally carried out in a vulcanization tank or a vulcanization box. During operation, high-temperature gas is introduced to achieve the vulcanization operation of compressed air. With the advancement of technology, rubber belt vulcanization devices using compressed air heating have emerged, but the current devices still have some shortcomings.

[0003] Hot air is directly sprayed into the vulcanizer to achieve heating and vulcanization of the rubber belt. However, the gas blows directly onto the rubber belt, and the contact area between the hot gas and the rubber belt is small, which is not conducive to uniform vulcanization of the rubber belt. Secondly, there is a lack of a guide mechanism in the vulcanizer, and the circulation of hot gas cannot be achieved, resulting in high energy consumption and slow vulcanization speed. There are certain defects and shortcomings, and therefore, improvements are needed. Utility Model Content
