Abstract

A grinding roller air-tight wind passage system comprises a wind machine, outer line pipes, a soft connector, line pipes fixed on the pressure frame, a upper roller seat, an air-tight roller, a lower roller seat, a grinding roller bracket and a grinding roller. Wherein, an air-tight wind passage is formed on the upper roller seat, the air-tight roller and the lower roller seat and is communicated with the wind holes on the grinding roller bracket. The wind machine blows positive pressure wind directly into the air-tight wind passage formed by the upper roller seat, the air-tight roller and the lower roller seat through the outer line pipes and the line pipes fixed on the pressure frame and blows the wind out from the gap between the grinding roller bracket, the grinding roller and the rotating pieces driven by the grinding roller through the wind holes on the grinding roller bracket. The grinding roller air-tight wind passage system resolves the problem that the ring-shaped line pipes and the wind inlet pipe of the grinding roller bracket tend to be abraded to leakage resulted from long term vibration of the grinding machine and the scour of the wind comprising power and dust or the rigid damage to leakage resulted from the severe vibration of the grinding machine. The grinding roller air-tight wind passage system can not only save a great amount of investment and reduce cost, but also is credited as a reliable grinding roller air-tight wind passage system.
