Description

Technical Field

[0001] The invention relates to the field of inner tube production equipment, in particular to an inner tube vulcanizer. Background Art

[0002] During the production of inner tubes, they need to be heated and vulcanized. The inner tube is made of rubber and cannot maintain its shape before inflation. It needs to be arranged in the vulcanization device for accurate alignment, which is time-consuming. In addition, the inner tube needs to be inflated during vulcanization, and the inflation time affects the overall vulcanization time.

[0003] Moreover, the existing vulcanization device generally includes a heated upper mold and a lower mold, the lower mold is placed horizontally, and the upper mold can be raised and lowered in the vertical direction relative to the lower mold. When the inner tube is vulcanized, the inner tube is placed in the lower mold, the upper mold descends and closes with the lower mold, the upper mold and the lower mold heat and vulcanize the inner tube, and after the vulcanization is completed, the upper mold rises and the inner tube is taken out. However, when the inner tube is processed in the existing vulcanization equipment, it is inconvenient to take it in and out, and it is easily interfered by the upper mold, and the action of the air nozzle is also inconvenient to implement.
