It is a process in which crosslinking aids such as vulcanizing agents and accelerators are added to rubber, and under certain temperature and pressure conditions, linear macromolecules are transformed into three-dimensional network structures. Conveyor belt vulcanization refers to a production process in which a rubber conveyor belt blank is led into a flat vulcanizing machine and undergoes heating and pressing treatment to become a rubber conveyor belt product with properties such as strength, elasticity, and wear resistance.

It includes an upper vulcanizing plate that can be lifted vertically, and a lower vulcanizing plate is correspondingly arranged at the bottom. Pad irons are installed on both sides in the length direction of the lower vulcanizing plate through retaining pads. The retaining pads can approach or move away from each other under the drive of a stretching and moving mechanism to adapt to conveyor belts of different widths. Sealing covers are installed around between the upper and lower vulcanizing plates. The sealing covers include side covers arranged along the length direction and end covers arranged along the width direction.
