[0002] The tire is mainly composed of an outer tube, an inner tube, and a cushion belt. The inner tube is an important part of the tire. The commonly used inner tube joint production process is as follows: tube confirmation, confirm that the tube specifications are consistent with the required specifications; tube width, thickness, and length inspection, check the tube size; confirm the docking vulcanization time pressure and temperature; product self-inspection, confirm that the joint has no bruises, internal cracks, and impurities; quality inspection, spot check the tube joints, and use destructive inspection for joint bruises and internal cracks.

[0003] During the processing of inner tubes, the joints of the inner tubes need to be heated to make them melt together. Heating the inner tube will inevitably cause the inner tube rubber to adhere to the heating device. Over time, rubber residues will accumulate on the surface of the heating device. The residues will hinder the heat transfer and affect the processing of the inner tube. Therefore, we need to consider how to solve this problem. Utility Model Content
