After the first vulcanizing group is vulcanized, the steam in the air bag 43 is released, the steam in the vulcanizing roller 32 is transferred to the vulcanizing roller 32 with the vulcanizing function of the second group through the air suction pump 351, and the pressurizing motor 421 drives the pressurizing block 41 to return to the original position. The conversion motor 131 drives the fixing plate 2 to move, the vulcanization group to be vulcanized is conveyed into the mounting frame 12, and the conversion motor 131 stops according to the first proximity switch 14; the vulcanized vulcanizing roller 32 is driven to rotate by the conversion motor 131, so that half of the vulcanized V belt is emptied, and water spraying cooling is carried out outside the mounting frame 12.

The pressurizing motor 421 drives the pressurizing block 41 to be fitted to the circumferential surface of the vulcanizing roller 32 of the second group again, then the vulcanizing roller 32 to be vulcanized is supplemented with steam, the air bag 43 is charged with steam, the amount of steam supplemented to the vulcanizing roller 32 is supplemented according to the temperature when the steam is released, and then vulcanization can be performed.

And after the V belts of the second group are completely vulcanized, the V belts are converted into V belts of unvulcanized parts of the first group to be vulcanized and are circulated in sequence, and when the V belts are completely vulcanized after being vulcanized twice, the V belts can be detached and replaced by new V belts vulcanized.

When the size of the V-belt to be vulcanized changes, the matching vulcanizing roller 32 may be replaced, thereby meeting the vulcanization requirements of V-belts of different sizes.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
