Description

TECHNICAL FIELD

[0001] The utility model relates to a label technical field especially relates to a special quick hot-press vulcanization label for electric vehicle and motorcycle. BACKGROUND

[0002] The existing electric vehicle and motorcycle tire will be fused with a color label through a vulcanization process at the tire side position, and the color label will accompany the whole cycle of tire use. This color label has become a standard configuration of electric vehicle and motorcycle tires.

[0003] The existing process of fusing the color label into the tire is as follows: the color pattern is printed on the film using raw rubber ink, and then the film is placed into the tire production mold. Through the tire vulcanization process, the raw rubber ink and the tire are cross-linked when the raw tire embryo becomes a mature tire, so that the color pattern is cross-linked to the tire side. The current pain points of this process are as follows: the label film must be carefully placed into the specified standard area of the tire mold by workers one jar at a time when the tire is vulcanized, and the placement position is checked again and again. The workers carefully pull out their hands. Even so, due to the existence of the ventilation system in the workshop and the convex curvature of many molds, the thin film label often deviates from the position after being placed correctly when the mold is closed, resulting in unqualified trademark position of the finished tire, which leads to degradation or scrap of the tire. The defect rate caused by this method has been high, but there is no solution.

[0004] In the process of rapid development of production automation today, this label fusion method also seriously hinders the progress of the vulcanization process automation. Since the vulcanization mold produces smoke in production, different types of tires correspond to different molds, and the mold has a lot of parameter text, patterns, and exhaust holes, leaving very limited space for the placement of the trademark film. At present, only manual placement of the trademark film can be used, but this method seriously hinders the development of unmanned vulcanization process. And in the vulcanization process, personnel will inevitably inhale toxic smoke and other gases, causing adverse effects on health. UTILITY MODEL CONTENTS
