Description

Technical Field

[0001] The utility model relates to an oil ingress prevention device for a centering lamp tube. Background Art

[0002] At present, the aluminum strip needs to be aligned and adjusted before rolling to avoid damage to the strip caused by subsequent rolling due to the position deviation of the aluminum strip. The existing alignment mechanism generally adopts the method of setting a bottom lamp tube and a top infrared detector at the input port of the rolling mill to perform alignment detection, and then perform manual alignment according to the detection result. However, since there will be a certain oil film on the aluminum strip, during the transportation process, due to the shaking of the aluminum strip itself, oil mist will be formed and emitted. The oil mist will adhere to the outer wall of the lamp tube assembly. After accumulating to a certain extent, the oil will enter the lamp tube through the gap of the lamp tube assembly, causing insufficient lighting. In severe cases, it will even damage the lamp tube, which will cause inaccurate alignment problems, equipment shutdown for maintenance, and slow down production progress. Summary of the invention
