Beating-up box for air-jet loom

Abstract

The invention relates to a beating-up box for air-jet loom. A large cover plate is sequentially and inwardly provided with an outer conjugate cam plate, an inner conjugate cam plate, and a first-stagedriving gear which pass through a loom main shaft of a main box body; a swing shaft penetrates through the main box body; the above-mentioned three components pass through a large carrier gear shaft,a planet hinged edge transmission shaft and a back rod swing eccentric cam driving shaft which are in gear meshed transmission in sequence; the other end of the swing shaft penetrates into the box body and is fixedly connected with a main power arm and a secondary power arm; the secondary power arm and the main power arm are provided with an inner rotor and an outer rotor respectively; an adjustment hole with a small sealing plate, corresponding to the position of the main power arm and the outer rotor, is formed in the large cover plate; the planet hinged edge transmission shaft is externally connected with a planet edge hinging machine; the back rod swing eccentric cam driving shaft is fixedly provided with an upper eccentric shaft section and is connected with a back rod swing eccentric cam; and the back rod swing eccentric cam is connected with a yarn guiding shaft through a back rod. By virtue of the beating-up box, the stop weft insertion time of more than or equal to 60 degrees, and higher beating-up force can be both considered, and beating up, edge hinging, and cam rotor interval are adjustable without interfering with other parts of the loom.

Description

technical field [0001] The invention relates to a loom, in particular to a beating box of an air-jet loom. Background technique [0002] The main shaft of the air-jet loom rotates at a constant speed of 360 degrees, and the beating-up reed must have enough pause time during weft insertion to allow the airflow to blow the weft yarn to the end in the air groove of the air-jet shaped reed, and it also needs to be replaced after the weft insertion is completed. The weft yarn hits the weaving point at the front end of the loom at 0 degrees quickly and powerfully. The longer the pause time at the farthest position from the beating point, the more time for weft insertion, the lower the air pressure requirement for weft insertion, and the faster the speed of the machine; The fuller the cloth style, the wider the range of adaptation to heavy varieties. [0003] Existing air-jet looms with a width of 280cm normally run within 550 rpm basically use an eccentric crank to drive the sle...

Problems solved by technology

The other rotor corresponds to the cam piece close to the large cover plate, combined with the shape of the cam piece, this structure is unscientific and cannot realize air-jet beating-up and weft insertion feasiblely
