Problems solved by technology

The speed of the previous generation of flexible rapier looms was 200-350 rpm. In order to increase the speed, various companies have made different attempts, but the further increase of the speed is limited by its overall structure, especially the weft insertion mechanism. It is impossible to increase the speed to 500~700 rpm

Embodiment Construction

[0014] Such as Figure 1-3 As shown, a crank and rocker weft insertion mechanism of a flexible rapier loom is composed of a crank 1, a rocker 2, a large pendulum 3, a connecting rod 4, a sector gear 5, a dial shaft 6, a rapier belt and a rapier head 7 The crank is fixed on the main shaft, the crank is connected to the rocker, the rocker is connected to the pendulum, the connecting rod is connected to the pendulum and the sector gear, the dial shaft is meshed with the sector gear, and the dial shaft is connected to the sword belt and the sword head.

[0015] The specific working process of this kind of crank rocker weft insertion mechanism is: the crank 1 fixed on the main shaft rotates under the drive of the main shaft, drives the rocker 2 to move in space, the rocker moves to drive the pendulum 3 to swing, and the connecting rod 4 Connected with the large pendulum and the sector gear 5, the connecting rod 4 transmits the swing of the large pendulum 3 to the sector gear 5, and...

Abstract

The invention relates to a crank rocker weft insertion mechanism for a rapier loom. The crank rocker weft insertion mechanism consists of a crank, a rocker, a giant swing, a connecting rod, a sector gear, a driving plate shaft, a rapier band and a rapier head, wherein the crank is fixed on a main shaft and is connected with the rocker; the rocker is connected with the giant swing; the connecting rod and the giant swing are connected with the sector gear; the driving plate shaft is meshed with the sector gear and is connected with the rapier band and the rapier head. By the weft insertion mechanism, the weft insertion speed of the rapier loom is improved, so that the rotation speed of the loop can be improved, and the weaving speed can reach 500 to 700 revolutions / minute; and the crank rocker weft insertion mechanism is compact in structure, simple in parts and low in manufacturing cost.

Description

Technical field [0001] The invention relates to a rapier loom, in particular to a weft insertion mechanism composed of a crank rocker of a flexible rapier loom. technical background [0002] The flexible rapier loom has a development history of 60 years from its invention to the present. The technological progress of the rapier loom keeps up with the progress of the industrial level. At present, the rapier loom has developed into a mechatronic and intelligent high-tech product . The speed has developed from the initial 50-60 rpm to the current 500-700 rpm, and technological innovation and technological progress are endless. The speed of the previous generation of flexible rapier looms was 200-350 rpm. In order to increase the speed, various companies have made different attempts, but the further improvement of the speed is limited by its overall structure, especially the weft insertion mechanism. It is impossible to increase the speed to 500-700 rpm. So it is necessary to...
