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 rolleris 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 beingshed, 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:
The present invention relates to mechanical field, relate in particular to textile machine, particularly circular loom, concrete is a kind of weft inserting apparatus of circular loom.
Background technology:
In the circular loom of prior art, power spreads out of from the center of circle of circular loom, promotes the weft yarn shuttle and passes from warp thread intersects opening, and realize the wefting insertion action.Move in the guide rail of roller in encircling up and down of weft yarn shuttle by its side and bottom, therefore can push warp thread.And because the promotion of outer side wheel, lower layer warp yarns is squeezed again at the push boat place.Thereby, during circular loom braiding intensity materials with smaller, can't weave.
Summary of the invention:
The object of the present invention is to provide a kind of weft inserting apparatus of circular loom, the weft inserting apparatus of described this circular loom will solve the technical problem of the wefting insertion structure extruding warp thread of circular loom in the prior art.
The weft inserting apparatus of this circular loom of the present invention, comprise ring, following ring, bobbin case and lease making sheet, wherein, described upward ring and described ring down be arranged in parallel up and down, described bobbin case is arranged between ring and the following ring, described lease making sheet is arranged between ring and the following ring, the back side of bobbin case is provided with tooth bar, be provided with gear shaft between last ring and the following ring, described gear shaft is provided with gear, described gear and the engagement of described tooth bar, comprise a boss plane in the lease making sheet, described boss plane, the plane that is parallel to ring and encircles down, form sliding pair between the bottom surface of tooth bar and the described plane, be provided with a gathering sill in the last plane of tooth bar, in the last ring to being arranged with a lead, the lower end of described lead extends in the described gathering sill, be provided with a through hole in the last ring, be provided with a pinch roller post in the described through hole, the lower end of described pinch roller post is connected with a pinch roller, the excircle of described pinch roller and the end face of tooth bar are tangent, the upper end of pinch roller post extends to the top of ring, and the upper end of pinch roller post is provided with a nut, is arranged with a spring on the pinch roller post between nut and the last ring.
Further, be provided with a nylon strip between the bottom surface of described tooth bar and the described plane.Nylon strip is fixed on the tooth bar bottom surface, in order to reduce friction.
Operation principle of the present invention is: gear is realized wefting insertion by the motion of rack drives bobbin case.Weft yarn is arranged in the shuttle frame, and spring is biased in pinch roller on the end face of tooth bar by the pinch roller post, and tooth bar closely is fitted on the lease making sheet boss plane all the time, guarantees the shuttle stable motion.Warp thread is passing between ring and the following ring along lower edge on the bobbin case behind the opening, and powerful extruding situation can not take place warp thread, can be fit to powerful more weak yarn, can knit the diameter smaller fabrics.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention adopts pinion and rack to drive shuttle in circular loom, and warp thread is introduced fell up and down respectively through bobbin case, has eliminated powerful extruding phenomenon, can be fit to the warp thread weaving that diameter is less and intensity is more weak.
Description of drawings:
Fig. 1 is the structural representation of the weft inserting apparatus of a kind of circular loom of the present invention.
The specific embodiment:
Embodiment 1:
