Vulcanizing device

The invention discloses a vulcanizing device. The vulcanizing device comprises a belt feeding mechanism, wherein the belt feeding mechanism comprises a first rack, a sliding platform, a mounting seatand a belt hanging module; a belt transferring mechanism, wherein the belt transferring mechanism comprises a first sliding trolley, a second sliding trolley, a second rack and two feeding assemblies;a vulcanizing mechanism, wherein the vulcanizing mechanism comprises a base, a stand column, a cross beam, a heating assembly, a lifting oil cylinder and a pressing oil cylinder; and a ground rail, wherein the ground rail is laid on the ground, one end of the ground rail extends to the vulcanizing mechanism, and the other end of the ground rail extends to the belt feeding mechanism. An operator sleeves a triangular belt on transferring rollers of the belt feeding mechanism outside a groove roller, then the transferring rollers of the belt feeding mechanism automatically sleeves the triangularbelt on the groove roller,
