Energy-saving heating plate of tire vulcanizing machine

Abstract

The invention discloses an energy-saving heating plate of a tire vulcanizing machine. The energy-saving heating plate of the tire vulcanizing machine comprises a heating plate body, wherein a plurality of linear holes which are recessed towards the center of a circle of the heating plate body are formed in an outer ring wall of the heating plate body; and a heating tube is inserted in each linear hole. Compared with a heating plate of a tire vulcanizing machine in a steam heating mode in the prior art, the electrothermic heating plate of the tire vulcanizing machine has the advantages that the sector heating temperature can be balanced, temperature equilibrium is maintained, the heating plate body of the tire vulcanizing machine can be heated uniformly, tire vulcanizing is uniform, meanwhile, the heat degree of the heating plate body of the tire vulcanizing machine is controlled conveniently, workmanship is simple, sealing is not required, the cost is low, a steamer is not required, and therefore, the energy-saving heating plate of the tire vulcanizing machine is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of vulcanizing machine heaters, in particular to an energy-saving heating plate for tire vulcanizing machines. Background technique [0002] The vulcanizing machine is mainly used for the processing and molding of silica gel and rubber products. Through the process of heating, pressurizing and heat preservation, the intermolecular structure of the raw material is urged to be finalized to achieve the required product. [0003] The vulcanization machine used in the market generally adopts steam heating method for tire vulcanization. This heating method is difficult to control the steam temperature stably. There is a temperature difference between the inlet and outlet, which may easily cause uneven tire vulcanization. Using steam heating requires very high sealing performance of the hot plate. No, once the hot plate leaks, the high-temperature and high-pressure steam will form condensed water when it is cold, ...

Problems solved by technology

[0003] The vulcanization machine used in the market generally adopts steam heating method for tire vulcanization. This heating method is difficult to control the steam temperature stably. There is a temperature difference between the inlet and outlet, which may easily cause uneven tire vulcanization. Using steam heating requires very high sealing performance of the hot plate. No, once the hot plate leaks, the high-temperature and high-pressure steam will form condensed water when it is cold, which will affect the uniformity of the mold temperature, resulting in partial undersulfurization of the tire during the vulcanization process, resulting in waste products, and the use of steam heating requires a large boiler, which increases the cost , and pollute the air, a large amount of heat is lost to the air during the steam transport from the boiler to the hot plate of the vulcanizer, resulting in a waste of energy

[0004] At present, there is no circular electric heating plate on the market, because the circular electric heating plate has the problem that the fan-shaped surface cannot be uniformly heated during the electric heating process, which limits the application of electric heating technology in the circular heating plate
