The rubber flat vulcanizing machine is mainly used for vulcanizing flat tapes (such as conveyor belts, transmission belts, abbreviated as flat belts), belonging to hydraulic machinery. The main function of the rubber flat vulcanizing machine is to provide the pressure and temperature required for vulcanization. Pressure is generated by the hydraulic system through hydraulic cylinders, and temperature is provided by heating media (usually steam, thermal oil, etc., superheated water is also useful). The conveyor belt flat vulcanizing machine is mainly used for the molding of flat products such as vulcanized tapes, rubber sheets, and polymers. It has the advantages of high pressure per unit area of the hot plate, reliable equipment operation, and low maintenance. The temperature is provided by the heating medium (usually steam, thermal oil, etc.). Flat belt flat vulcanizing machines can be mainly divided into two types according to the structure of the frame: column type flat belt flat vulcanizing machines and frame type flat belt flat vulcanizing machines; According to the number of working layers, there can be single-layer and multi-layer classifications; according to the working medium of the hydraulic system, there can be oil pressure and water pressure classifications.

The technical parameters of electric heating tubes mainly include: the working voltage of a single head heat pipe for vulcanization models is 220 (V) or 380 (V), the power used is made according to the temperature of the template, and the common pipe diameters are 14mm, 16mm, 18mm, etc. SUS304 seamless tube can be used as the material. The vulcanization usage condition is template heating, the surface is polished and blackened, and the sealing is made of glass sealing, epoxy resin, glue. The electrical performance is that the long-term storage edge value is greater than 50M Ω, and the leakage current is less than 0.5mA.

The main technical requirements for a rubber flat vulcanizing machine are: the operating temperature is usually 180-200 ° C, and the surface load of a conventional electric heating tube should be 3-7W/square centimeter to ensure uniform surface temperature of the flat vulcanizing machine template. The reasonable arrangement of the template hole spacing should control the temperature difference on the hot plate surface within a small range. At the same time, considering the convenience of installing and using the electric heating tube, a star connection method is generally used.

The rubber flat vulcanizing machine electric heating tube is a specially designed electric heating element for electric flat vulcanizing machines. The flat vulcanizing machine is the main vulcanizing equipment for rubber products, and its hot plate surface temperature difference is the main performance indicator of the balanced plate vulcanizing machine. There are two main reasons for the large temperature difference on the hot plate surface: 1. The influence of external environmental temperature; 2. The spacing arrangement design of electric heating tubes, therefore, the key to solving the temperature difference problem on the surface of the electric heating plate vulcanizing machine is to find the relationship between small temperature differences and the spacing arrangement of electric heating tubes.
