The utility model is set to further: arrange for locking the fixed sturcture that headstock gear makes split channel open in described secondary air knife.
By adopting technique scheme, fixed sturcture is another use-pattern, headstock gear is in normally open, now split channel is opened, main air knife and secondary air knife work simultaneously, secondary air knife can suppress longitudinal whirlpool of main air knife air-flow periodically mobile, improves air knife and blows zinc ability and improve strip surface quality.
The utility model is set to further: described fixed sturcture comprises elastic bumps on closure plate, and the sidewall of secondary air knife arranges groove, and elastic bumps snaps in headstock gear after in groove and fixes.
By adopting technique scheme, fixed by headstock gear with coordinating of groove by elastic bumps, elastic bumps is initially located in compressed state, when closure plate Sports band dynamic elasticity projection is moved together, after elastic bumps and groove are aimed at, elastic bumps elasticity recovery snaps in groove.
The utility model is set to further: described fixed sturcture comprises slippage and is arranged on fixture block on closure plate, and the sidewall of secondary air knife arranges draw-in groove, and after fixture block card entry slot, headstock gear is fixed.
By adopting technique scheme, first compressed by elastic component, promote fixture block afterwards and slip in draw-in groove, closure plate is separated with the second lips, and elastic component is in confined state all the time, and split channel is in opened condition.
The utility model is set to further: described fixture block is magnet, and described closure plate is iron.
By adopting technique scheme, by magnet and closure plate adhesive, prevent fixture block from moving, and structure is simple.
The utility model is set to further: described closure plate arranges rubber plate, and described rubber plate is arranged on the second lips side.
By adopting technique scheme, fitted by rubber plate and the second lips, because rubber plate exists elasticity, therefore better tightness, when preventing from not needing secondary air knife work, gas enters secondary air knife from split channel.
