Improved structure of weft insertion pump of hydraulic loom

Abstract

Discloses is an improved structure of a weft insertion pump of a hydraulic loom. Spiral springs are inserted into a spring seat in a sleeved mode, a spring cap is in screw joint with a pump body, the spiral springs and the spring seat are arranged in the spring cap, the right ends of the spiral springs are pressed on flanges of the spring seat, the right ends of the spiral springs are pressed on a rubber gasket, a graphite block is embedded into a guide ring in a sleeved mode, the left end of the spring seat is inserted into the guide ring in a sleeved mode, a guide ring cap edge is formed in the guide ring, the rubber gasket is pressed on the guide ring cap edge, and the guide ring cap edge is pressed on the spring cap. A connecting rod is inserted into the spring seat in a sleeved mode, the connecting rod is hinged to one end of a connecting piece, the other end of the connecting piece is hinged to a bent lever, the middle of the bent lever is hinged to a rack through a shaft, a wheel is arranged at the rear end of the bent lever, the wheel abuts against an eccentric wheel, and the eccentric wheel is driven by a motor to rotate. The rubber cushion block is designed to reduce the vibration of the spiral rings, meanwhile, the clearance between the spring seat and the spring cap is reduced to reduce the vibration of the spiral rings, and therefore pressure fluctuation of water flow jetted out of the weft insertion pump is slowed down.

Description

Technical field: [0001] The invention relates to the technical field of weft-jet looms, in particular to a weft-inserting pump for water-jet looms. Background technique: [0002] The spring seat of the weft insertion pump of the existing water-jet loom has a helical spring inserted into the sleeve, and the helical spring is prone to vibration during the working process. The pulsation of the water flow pressure will affect the normal weft picking of the weft yarn, which needs further improvement. At the same time, the spring seat reciprocates linearly during the working process. There is a large gap between the spring seat and the spring cap, and the spring seat is easy to shake slightly, which will inevitably cause the vibration of the coil spring and affect the normal water outlet pressure of the weft insertion pump. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the prior art, and to provide an improved structure for t...
