Weft insertion device of circular loom

Abstract

The invention discloses a weft insertion device of a circular loom, which comprises an upper ring, a lower ring, a bobbin case and a leasing plate. The bobbin case is arranged between the upper ring and the lower ring; the leasing plate supports the upper ring and the lower ring; a rack is arranged on the backside of the bobbin case; a gear shaft is arranged between the upper ring and the lower ring and a gear wheel meshed with the rack is arranged on the gear shaft; the leasing plate comprises a convex plane; the underside of the rack and the convex plane form a sliding pair; a guide device is arranged between the rack and the upper ring; a pinch roller column is arranged in the upper ring and the lower end of the pinch roller column is connected with a pinch roller; and the pinch roller is biased on the face of the rack by a spring to enable the rack to be tightly attached on the convex plane of the leasing plate all the time so as to ensure stable movement of a shuttle. After being shed, warps pass through the area between the upper and lower rings along the upper and lower edges of the bobbin case, and the gear wheel drives the bobbin case to move through the rack to realize weft insertion. With the weft insertion device, the warps can not be extruded by brute force, the weft insertion device can be suitable for yarns with weaker brute force and can be used for weaving fabrics with smaller diameters.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to textile machinery, in particular to a circular loom, and in particular to a weft insertion device for a circular loom. Background technique: [0002] In the circular loom of the prior art, the power is transmitted from the center of the circle of the circular loom to push the weft yarn shuttle to pass through the warp yarn intersection opening to realize the weft insertion action. The weft shuttle moves on guide rails in the upper and lower rings with the help of its side and bottom rollers, thus compressing the warp threads. And, due to the promotion of the outside rollers, the lower warp threads are squeezed again at the push rollers. Therefore, when circular looms weave materials with low strength, they cannot be woven. Invention content: [0003] The object of the present invention is to provide a weft insertion device of a circular loom, which solves the technical problem of th...
