Three-air-cylinder device for weaving machine

The utility model provides a three-air-cylinder device for a weaving machine. The three-air-cylinder device for the weaving machine is characterized by comprising three air cylinders. A pressure meter and a plurality of magnetic valves are arranged on the side wall of each air cylinder, and the air inlet end of each air cylinder is connected with an air supply pipeline through an air inlet branch pipe with an adjusting valve. One air cylinder in the original situation is replaced by the three independent air cylinders, the pressure of the air cylinders can be independently adjusted, according to the flight curve of a yarn, the pressure at the front section and in the middle of the yarn is lowered, the pressure at the tail end of the yarn is increased, and the magnitude of the pressure is controlled section by section. The three-air-cylinder device for the weaving machine is simple in structure and good and stable in working performance, and production cost can be lowered.
