Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a multi-station rotating mechanism for a heating furnace. Background Art

[0002] The resin tube is a resin tube with a multi-layer structure. The required raw materials are thermoplastic resins, etc. During the production of the resin tube, a curing agent needs to be added when the encapsulating resin is heated in a heating furnace to solidify the resin into shape. When the heating furnace heats and cures the resin tube, in order to ensure the uniformity of heating of the resin tube, a rotating mechanism needs to be used to drive the resin tube to rotate continuously in the heating furnace cavity.

[0003] When heating the resin tube, the resin tube is driven to rotate by a rotating mechanism, so that the resin tube is heated more evenly during heating. However, it is inconvenient for the rotating mechanism to quickly fix the resin tube during use, and the cylindrical structure of the rotating mechanism results in a small gap between the surface of the rotating mechanism and the inner wall of the furnace body, which makes it inconvenient to quickly take and place the resin tube during use. In order to solve the above problems, a multi-station rotating mechanism for a heating furnace is proposed in the present application. Utility Model Content
