Weft insertion and beating mechanism of a loom

Abstract

The invention relates to a wefting insertion beating-up mechanism of a loom.A wefting insertion eccentric wheel is fixedly connected with a main shaft.One end of a connecting rod is hinged to the wefting insertion eccentric wheel.The other end of the connecting rod is hinged to a wefting insertion triangular arm.One end of the wefting insertion triangular arm is hinged to a wefting insertion triangular arm rotary pivot shaft fixed to a machine frame.The other end of the wefting insertion triangular arm is hinged to one end of a short connecting rod.The other end of the short connecting rod is hinged to a fluted disc base except for the rotary circle center.A rocking shaft can be sleeved with the fluted disc base in a rotatable mode.A periphery fluted disc is fixed to the fluted disc base.The rocking shaft except for the rotary circle center is provided with one or more planetary bridge shafts.The planetary bridge shafts are rotationally sleeved with planetary bridge teeth which are meshed into the periphery fluted disc in the state of being meshed with a tooth ring of the inner ring of the periphery fluted disc.An inner planetary output tooth shaft is arranged at the circle center position of the periphery fluted disc to be meshed with the planetary bridge teeth in a transmission mode.The inner planetary output tooth shaft drives a rapier transmission tooth shaft through a driving mechanism.A rapier transmission wheel is fixedly arranged on the rapier transmission tooth shaft.A rapier belt is wound around the rapier transmission wheel.The rapier belt is provided with a rapier head in a reciprocating motion weft transferring state.

Description

technical field [0001] The invention relates to a loom, in particular to a weft insertion and beating-up mechanism of the loom. Background technique [0002] Traditional cloth machines and towel machines have many transmission parts for beating up and weft insertion, most of which are exposed outside, the parts are severely worn and noisy, and the existing beating and weft joining needs to be equipped with additional transmission devices, adding transmission equipment, high cost, and transmission beating. The coordination between the weft and the sley movement is poor, and there are design errors and work errors accumulated. After long-term use, the accuracy and stability of weft yarn transfer will be affected, and the weaving quality will be seriously affected. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a weft insertion and beating-up mechanism of a loom that has compact structure, less we...
