Using rotation connection, mutually matched upper knife lip and lower knife lip are installed on the cutter hub, are further fixed on the crossbeam
Knife interlabial gap regulating mechanism for upper knife lip described in on-line control and the interlabium gap of lower knife lip；
The knife interlabial gap regulating mechanism includes the driving motor being fixed on the crossbeam, the output shaft of the driving motor
It is connected with the first worm couple by retarder, which is connected by joint arm with the upper knife lip.
Further, the knife lip angle-adjusting mechanism includes the handwheel for being fixed on the beam-end, which passes through
Connecting rod is connected with the second worm couple, the shaft phase which passes through third worm couple and the cutter hub
Connection.
Further, it is fixed with the angle for showing knife labial angle degree on the crossbeam and shows pointer.It is aobvious by angle
Show that pointer may insure that angle adjustment is more convenient, accurate and simple in structure, manufacturing cost is low.
Further, the knife interlabial gap regulating mechanism further includes for showing that the gap of lip gap shows pointer.It is logical
It crosses gap and shows that pointer may insure that gap adjustment is more accurate and simple in structure, manufacturing cost is low.
Further, at least two suspension hooks are further fixed on the crossbeam, to facilitate the dismounting and maintenance of air knife.
Further, the bottom at the crossbeam both ends is both provided with detent mechanism, in order to the installation of air knife.
The present invention remarkable result be：The air knife can be directed on the timely on-line tuning of variation of air-flow and cut interlabial gap,
And air knife integral demounting is hung into zinc pot without stopping production, adjustment time is greatly saved, improves operation rate；It uses simultaneously
Motorized adjustment mode solves the problems, such as that regulation technology difficulty is big, it is high to require instead of manual adjustment so that on cut
Interlabial gap remains at optimum state, and then it is smooth to be effectively ensured strip steel Zn-plating face, improves product quality；In addition, setting
Air cavity is set to replace the air flue in traditional technology so that the air-flow air pressure that air flue sprays more is stablized, and product matter is helped to improve
Amount.
