Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizing machines, in particular to an automatic flat plate vulcanizing machine. Background Art

[0002] Rubber is a polymer elastic material, which is divided into two categories: natural rubber and synthetic rubber:

[0003] Natural rubber comes from rubber trees, mainly Hevea brasiliensis, which is processed by collecting latex through tapping and then coagulating and drying. Natural rubber has excellent elasticity, toughness, plasticity and tensile strength, and is widely used in tires, hoses, tapes, seals, shoe materials and other fields;

[0004] Synthetic rubber is a synthetic polymer material. According to different monomers and polymerization processes, various types of synthetic rubber can be obtained, such as styrene-butadiene rubber (SBR), butadiene rubber (BR), isoprene rubber (IR), chloroprene rubber (CR), etc. Synthetic rubber can simulate the properties of natural rubber, and rubber varieties with special properties can also be designed according to needs to meet the application requirements of different fields.

[0005] Rubber vulcanization, also known as rubber cross-linking, is one of the key steps in the rubber processing process. In this process, raw rubber or semi-finished rubber forms a three-dimensional network structure through a chemical reaction with sulfur or other cross-linking agents, thereby giving the rubber better physical properties, elasticity and aging resistance.

[0006] A vulcanizer is a device used to vulcanize rubber. It usually refers to a machine that converts raw rubber or semi-finished rubber products into vulcanized rubber with specific properties through a vulcanization reaction under a certain temperature and pressure.

[0007] Vulcanization is an important step in rubber processing, which can make rubber obtain better physical properties, aging resistance and chemical stability.

[0008] Vulcanizers are widely used in the rubber industry to manufacture various rubber products such as tires, hoses, tapes, seals, etc. The flat plate vulcanizer is the most basic vulcanization equipment. It consists of an upper plate and a lower plate, and vulcanizes rubber products through heating and pressurization.

[0009] At present, conventional rubber plate vulcanizers use electric heating plates as heating components when heating and vulcanizing rubber. Through the heat conduction effect, the plate seat holding the rubber plate can be heated, thereby ensuring the stability of the vulcanization process. However, most of the heating plates are fixed to the plate seat by welding, resulting in relatively cumbersome removal from the vulcanizer when problems occur with the heating plate, which is not conducive to quick inspection by workers.
