Shuttle pushing mechanism of small-cam circular weaving machine

Abstract

The invention discloses a shuttle pushing mechanism of a small-cam circular weaving machine, comprising a propulsion arm, wherein the outer end of the propulsion arm is rotationally connected with a propulsion wheel, the propulsion wheel is in rolling contact with a shuttle tail wheel at the front end of the propulsion wheel, a driven gear is fixedly mounted at the inner end of the propulsion wheel, the propulsion arm is rotationally connected with a friction wheel bracket in the inner side of the driven gear, a spring seat of the propulsion arm is fixedly mounted on the inner side of the friction wheel bracket, the rear side of the friction wheel bracket is fixedly connected with a friction wheel mandrel, a friction wheel is rotationally connected to the friction wheel mandrel, the friction wheel is arranged at the rear side of the propulsion wheel and is lower than the propulsion wheel, a spring is arranged between the inner end of the friction wheel mandrel and the spring seat, the friction wheel is in rolling contact with a friction wheel track, a driving gear is fixedly mounted at the inner end of the friction wheel, and the driving gear is meshed with the driven gear. According to the shuttle pushing mechanism, the reversal resistance from the friction wheel track in the operating state is greatly reduced, no vibration is caused, and warp yarns are enabled to smoothly pass through between the propulsion wheel and the shuttle tail wheel without being broken.

Description

technical field [0001] The invention relates to a component of a plastic circular loom, in particular to a shuttle pushing mechanism of a small cam circular loom. Background technique [0002] The small cam circular looms manufactured and used at present place the friction wheel under the front end of the advancing direction of the propulsion wheel, and use spring tension to keep the friction wheel close to the track all the time, and push it forward by the friction bracket on the propulsion arm. The reverse resistance when it advances is due to the angle of the force. The greater the resistance, the greater the friction wheel pressing on the track, the greater the friction force, the greater the friction force, the greater the resistance, so the chain reaction is very easy to cause vibration, so that the warp thread passes through the push wheel and the shuttle. When the tail wheel is turned, it will cause disconnection, and the noise will be loud, and the resistance will i...

[0002] The small cam circular looms manufactured and used at present place the friction wheel under the front end of the advancing direction of the propulsion wheel, and use spring tension to keep the friction wheel close to the track all the time, and push it forward by the friction bracket on the propulsion arm. The reverse resistance when it advances is due to the angle of the force. The greater the resistance, the greater the friction wheel pressing on the track, the greater the friction force, the greater the friction force, the greater the resistance, so the chain reaction is very easy to cause vibration, so that the warp thread passes through the push wheel and the shuttle. The tail wheel will cause disconnection, and the noise will be loud, and the resistance will increase the energy consumption
