[0002] The rubber strip vulcanization device is usually called a vulcanizer. The vulcanizer is suitable for the vulcanization of various rubber products. It integrates the preheating required by the rubber vulcanization process, automatic exhaust gas after loading, pressure-maintaining vulcanization, timing alarm, automatic mold opening, and product demolding. It is mainly used for the molding of flat products such as vulcanized flat tapes, rubber sheets, and polymers. The rubber strip vulcanization joint is a flat conveyor belt or conveyor belt. When the flat vulcanizer is used for vulcanization, it is divided into sections according to the length of the vulcanizer. Each section is contacted first, and a small section is required to connect to the next section for vulcanization. After pressurization vulcanization once, this small section is called a vulcanization joint. The vulcanization of this part adopts cooling water to reduce the vulcanization temperature to avoid over-vulcanization.

[0003] Common vulcanization equipment is composed of vulcanization tanks, columns, transformers, hydraulic cylinders and other parts. The transformer is generally sealed with an annular sealing rubber ring, which is made by cutting a circular rubber strip to a suitable length and bonding the two ends with quick-drying glue.
