The conveyor belt joint vulcanizer is a device used for vulcanizing the joints of conveyor belts. Here is a brief introduction to it:
Working Principle
Through heating and applying pressure, the rubber at the joint of the conveyor belt undergoes a vulcanization reaction, firmly connecting the two ends of the conveyor belt together to form a whole, thereby restoring the strength and tightness of the conveyor belt.
Structural Composition
- Heating plate: It provides the heat required for vulcanization and usually adopts an electric heating method, and the temperature can be precisely controlled.
- Pressure system: It includes a hydraulic device or a mechanical pressurization device, which can apply uniform pressure to the joint of the conveyor belt during the vulcanization process.
- Control system: It is used to set and monitor parameters such as vulcanization temperature, pressure, and time to ensure that the vulcanization process is carried out according to the technological requirements.
- Frame: It supports and fixes components such as the heating plate and the pressure system to ensure the stability and rigidity of the equipment.
Classification
- According to the structural form, it can be divided into flat vulcanizers, drum vulcanizers, etc. Flat vulcanizers are suitable for the vulcanization of conveyor belt joints of various specifications; drum vulcanizers are often used for the continuous vulcanization of longer conveyor belts.
- According to the heating method, it can be divided into electric heating vulcanizers, steam heating vulcanizers, and gas heating vulcanizers, etc. Electric heating vulcanizers are clean and have precise temperature control; steam heating vulcanizers require a steam supply system and have a relatively low cost; gas heating vulcanizers have a large heating power, but safety needs to be paid attention to.
Characteristics and Advantages
- It can ensure a high vulcanization quality at the joint of the conveyor belt, and the strength of the joint can reach more than 80% - 90% of the strength of the conveyor belt itself, greatly increasing the service life of the conveyor belt.
- The vulcanization process has a high degree of automation, and the parameters can be precisely controlled. It is easy to operate, which can effectively improve work efficiency and reduce labor intensity.
- The equipment has a compact structure, is easy to move and install, and can be used in different workplaces, applicable to multiple industries such as coal mines, ports, mines, and power plants.
