Siphon end structure for steam heating roller

The utility model discloses a siphon end structure for a steam heating roller. Belonging to the field of machinery, the utility model mainly relates to an end structure of a siphon of a condensed water siphon system of a steam heating roller. An inner cavity is formed in a roller body of the steam heating roller. The two ends of the roller body are each fixedly connected with a shaft head. One endof each shaft head extends into the roller body; one shaft head of the roller is of a through hole structure; the siphon is provided with a protective end part; the protective end part can absorb andavoid fatigue impact on the siphon caused by impact of the roller through easy deformation or easy abrasion or scalability and the like relative to the siphon; the technical problems that the siphongap needs to be minimized, and fatigue fracture caused by the fact that a siphon is prevented from being impacted by a high-speed running roller are solved. 本专利公开了一种蒸汽加热辊子用虹吸管端部结构，属于机械领域，主要涉及蒸汽加热辊子之冷凝水虹吸系统之虹吸管之端部结构，所述蒸汽加热辊子的辊体内
