It is connected with air cavity and cutter hub, the distribution of air flow cylinder is connected by air cavity with the cutter hub, and between the cutter hub and knife rest
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, which passes through the shaft phase of 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 structure is simple, 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 structure is simple, 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 provided with positioning mechanism, in order to the installation of air knife.
The remarkable result of the utility model is: the air knife can be between lower knife lip on the timely on-line tuning of variation of air-flow
Gap, and air knife integral demounting is hung into zinc pot without stopping production, adjustment time is greatly saved, improves operation rate；Simultaneously
Using motorized adjustment mode, instead of manual adjustment, solve the problems, such as that regulation technology difficulty is big, demanding, so that on
It cuts interlabial gap and remains at optimum state, and then it is smooth to be effectively ensured strip steel Zn-plating face, improves product quality；Separately
Outside, setting air cavity, so that the air-flow air pressure that air flue sprays is more stable, helps to improve production to replace the air flue in traditional technology
Quality.
