Abstract

The utility model relates to a slanting furrow yarn gripper structure on a rapier head of a rapier loom, comprising an upper plate, a mounting hole, an upper plate yarn gripping surface, a protruding shoulder, a lower plate and a lower plate yarn gripping surface. The technical point mainly lies in the fact that both the yarn gripping surface on the upper plate and the yarn gripping surface on the lower plate are provided with a plurality of slanting furrow grooves, thereby increasing the friction between the two yarn gripping surfaces and weft yarns, ensuring that the weft yarns are not easy to slip off from the yarn gripping surfaces, reducing the phenomenon of stopping the operation because of broken weft yarns and improving the productivity of the rapier loom.

Description

Skewed slot line yarn gripper structure on the Rapier looms sword head

One, technical field

The utility model relates to the skewed slot line yarn gripper structure on the Rapier looms sword head, is a kind of vitals that can make Rapier looms carry out the weft yarn handing-over at work smoothly.

Two, background technology

The weft yarn handing-over of Rapier looms is to lean on the yarn gripper of sword head to send to finish, and the yarn gripper on the sword head is the vitals of weft yarn handing-over, and mostly there is such shortcoming in common yarn gripper at present: all be the yarn clipping position of yarn gripper to make smooth surface promptly.Quite extensive because of the applicable surface of Rapier looms, natural fabric (cotton, hair, fiber crops, silk), artificial fibre and synthetic fiber can be woven into gently, approach, in thick, heavily fabric.And the smooth yarn clipping surface of yarn gripper to the tension friction deficiency that produces of woven fiber, clamping force is obviously less than normal, weft yarn skids off from yarn gripper than being easier in handshaking, causes staplings parking phenomenon.

Three, summary of the invention

Smooth at the surface of the yarn gripper yarn clipping on above-mentioned common Rapier looms sword head ubiquity, weft yarn skids off from yarn gripper than being easier in handshaking, causes the staplings phenomenon.The utility model technical issues that need to address are to overcome the defective that exists in the prior art, the purpose of this invention is to provide a kind of weft yarn handing-over success rate that can make and improve the skewed slot line yarn gripper structure on the Rapier looms sword head of minimizing staplings phenomenon.

Technical scheme of the present invention is: it comprises: last slice 1, install in perforation 2, last slice yarn clipping face 3 explanations: all remove bracket.Convex shoulder 4, down sheet 5, sheet yarn clipping face 6 down is characterized in that: last slice 1 last slice yarn clipping face 3 is provided with some skewed slot line strias; A following yarn clipping face 6 of following sheet 5 is provided with some skewed slot line strias, and the convex shoulder 4 of following sheet 5 is installed together by last slice 1 installation perforation 2, and last slice yarn clipping face 3 fits together with corresponding sheet yarn clipping face 6 down, as shown in Figure 3.Its advantage is that a following yarn clipping face 6 of slice 1 last slice yarn clipping face 3 and following sheet 5 is provided with many and makes with extra care smooth skewed slot line strias, when entering yarn clipping face because of weft yarn, has certain angle, some skewed slot line strias on the yarn gripper are made perpendicular to weft yarn enter angle, helping weft yarn enters in the yarn gripper yarn clipping face more swimmingly, while, some twill strias can increase the frictional force between two yarn clipping faces and the weft yarn, weft yarn is not easy to skid off from yarn gripper, reduce staplings parking phenomenon, thereby reached the success rate that improves clamp.

Five, the specific embodiment

Implementation process in conjunction with the yarn gripper on Fig. 1,2, the 3 pairs of the utility model Rapier looms sword heads is described further: the convex shoulder 4 on following 5 of yarn gripper is installed together by last slice 1 installation perforation 2, a yarn clipping face 3 and following sheet yarn clipping face 6 are fit together.Rubber on the bottom surface pad of following sheet is fixed on sending on the sword shell of sword head with screw with yarn gripper and gets final product again.In use, last slice last slice yarn clipping face 3 of 1 makes with extra care smooth skewed slot line strias because being provided with many with 5 times sheet yarn clipping faces 6 of following sheet, increased the friction between corresponding two yarn clipping faces and the weft yarn, make weft yarn be not easy from weft yarn yarn clipping face, to skid off, reduce staplings parking phenomenon, improved productivity.According to woven kinds of fibers difference, adjust the rubber front and back position that the sheet bottom surface is filled up under the yarn gripper, can obtain different clamping forces, to adapt to the scope of weaving of Rapier looms broadness.
