TECHNICAL FIELD
[0001] The present application belongs to the technical field of tire manufacturing, and particularly relates to a tire vulcanization equipment for vulcanization treatment of tires. BACKGROUND
[0002] The vulcanization process is widely used in industrial production. Through vulcanization treatment, the overall hardness of certain materials can be improved, for example, the hardness of rubber and the like. Rubber is one of the main materials for manufacturing tires. The outer tire supported by rubber is a plastic rubber with viscoelasticity before undergoing vulcanization treatment, which is easy to deform and has low strength. After vulcanization, the rubber is solidified and has high strength and elasticity.
[0003] The traditional tire vulcanization process usually adopts a combination of saturated steam and nitrogen to perform vulcanization. The vulcanization process is as follows: first, an unvulcanized green tire is placed between a sealed vulcanization bladder and a vulcanization mold; then, saturated steam is introduced into the vulcanization bladder, which can provide the heat required for vulcanization; and then high-pressure nitrogen is introduced to provide the pressure required for vulcanization. Under the action of the heat of the saturated steam and the pressure of the high-pressure nitrogen, the vulcanization bladder expands and presses and heats the green tire to perform sizing and vulcanization operations on the green tire.
[0004] One of the problems of the steam vulcanization machine in the running process is that the steam entering the vulcanization bladder will condense, and the condensed water will accumulate in the lower part of the vulcanization bladder, causing a large temperature difference between the upper and lower parts of the vulcanization bladder, which will affect the vulcanization effect of the tire. Moreover, in order to supply steam to the vulcanization bladder, a steam pipeline needs to be arranged, which will occupy a large space.
[0005] In view of these problems of the steam vulcanization machine, an electric vulcanization system is proposed in the prior art, which includes a heating and ventilation device to heat the gaseous medium in a closed chamber.

In the existing electric vulcanization system, the closed chamber is filled with gaseous medium, and the components such as the motor, the agitating device and the heating device are also located in the closed chamber. In this way, the heating device in the vulcanization bladder heats the gaseous medium in the vulcanization bladder, and there are problems such as slow heating rate, insufficient vulcanization efficiency and quality in the tire vulcanization process.
