[0002] During the production process of traditional paper cup machines, the hot air heating device, as one of the key components, has an important impact on the forming quality and production efficiency of paper cups. However, the hot air heating devices of traditional paper cup machines in the prior art generally face a significant technical problem, that is, the instability of their lifting structures. Specifically, the hot air heating device of a traditional paper cup machine usually includes one or more hot air head components, which are designed to preheat and subsequently heat the paper material at specific stages of paper cup forming to ensure the strength and tightness of the paper cup. However, due to design defects or improper material selection of the lifting mechanism, these hot air head components often shake or shift during the lifting process, resulting in the inability to precisely control the preheating and subsequent heating positions. This positional instability directly affects the uniformity and consistency of the heating effect, not only reducing the yield rate of paper cups but also affecting the overall quality and appearance of paper cups. Therefore, it is necessary to solve the above technical problems. Summary of the Invention
