Description

Tricot machine sley point

Technical field

The utility model relates to the knitting needles in a kind of comb mechanism of warp knitting machine, more particularly to institute in comb mechanism of warp knitting machine The sley point used.

Background technique

Sley point used in existing comb mechanism of warp knitting machine, as shown in Figure 8,9 comprising shank 11 and syringe needle 12； Syringe needle 12 is rounded or oval, and the guide eyelit 12a for entrying is offered on the syringe needle 12；When work, yarn 13 It is passed through from guide eyelit 12a, 13 transverse motion of yarn is driven by the reciprocating motion of sley point.

Existing sley point has the following deficiencies: that i.e. for general technique, existing sley point can in use To meet requirement, but for the technique of high requirement, such as the biggish technique of traversing amount (more than traversing 20 needle), yarn 13 are easy to be slid onto 12 side of syringe needle, as shown in figure 9, yarn 13 understands band yarn in the syringe needle of groove pin 14 in this way, so that dropped stitch is caused, Machine is caused to weave limited speed, Homes Using TV is lower, and reduces fabric quality.

Summary of the invention

The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide one kind to pass through simple structure, It can be effectively prevent dropped stitch, braiding speed can be promoted, the tricot machine sley point of production efficiency and weaving quality can be greatly improved.

In order to solve the above technical problems, the utility model uses such a tricot machine sley point, including shank and needle Head；The guide eyelit penetrated for yarn is offered on the syringe needle, be additionally provided on the syringe needle one can pass through it is described The yarn of guide eyelit is limited the position limiting structure passed through from syringe needle bottom surface.

As a kind of preferred embodiment of the utility model, the position limiting structure be arranged in it is recessed on syringe needle bottom surface The inclined-plane tilted down or setting on syringe needle bottom surface is perhaps arranged in slot, the horizontal plane being perhaps arranged on syringe needle bottom surface Inner sunken face on syringe needle bottom surface.

In the present invention, be arranged in the groove on syringe needle bottom surface be located at the guide eyelit side-lower or just under Side, the shape of the groove are arc-shaped or rectangle or trapezoidal.

After adopting the above structure, the utility model has the following beneficial effects:

The utility model is preferably arranged on recessed on syringe needle bottom surface by the way that position limiting structure, position limiting structure are arranged on syringe needle Slot or horizontal plane or the inclined-plane or inner sunken face tilted down, for such yarn when lopping weaves, yarn passes through quilt after guide eyelit It is limited on the syringe needle bottom surface of sley point and passes through, i.e., yarn can only pass through below the syringe needle of sley point, avoid yarn slip To the syringe needle side of sley point, to effectively prevent dropped stitch, the reliability of band yarn is significantly improved, lopping volume greatly improved Knit quality.

In the case that the utility model is more than larger i.e. traversing 20 needle of traversing amount, and it is smaller by i.e. traversing 20 in traversing amount In needle situation below, the reliability of band yarn can guarantee, snagging will not occur.

The utility model can be reduced band yarn depth, improve and hold yarn in the smaller i.e. traversing 20 needle situation below of traversing amount Gap, to keep lopping more reliable.

The utility model structure is simple, easily manufactured, improves tricot machine braiding speed and production efficiency.

Specific embodiment

Referring to Fig. 1 to a kind of tricot machine sley point shown in Fig. 7, sley point generallys use metalwork such as steel part, Including shank 1 and syringe needle 2；The guide eyelit 2-1 penetrated for yarn 3 is offered on the syringe needle 2, on the syringe needle 2 also The yarn 3 that the guide eyelit 2-1 can be passed through equipped with one is limited the position limiting structure passed through from 2 bottom surface of syringe needle.

As a kind of preferred embodiment of the utility model, as shown in Figures 1 to 7, the position limiting structure is that setting exists Groove 2a on 2 bottom surface of syringe needle, as shown in Figure 1, 2, 3；Or the horizontal plane 2b on 2 bottom surface of syringe needle is set, as shown in Figure 4； Or the inclined-plane 2c tilted down on 2 bottom surface of syringe needle is set, as shown in Fig. 5,7；Or in being arranged on 2 bottom surface of syringe needle Concave curved surface 2d, as shown in Figure 6.

As a kind of preferred embodiment of the utility model, the groove 2a being arranged on 2 bottom surface of syringe needle is located at described lead The side-lower of yarn hole 2-1 or underface, as shown in Figure 1,3, groove 2a are located at the side-lower of the guide eyelit 2-1；Such as Fig. 2 Shown, groove 2a is located at the underface of the guide eyelit 2-1；As shown in Figure 1, 2, the shape of the groove 2a is arc-shaped；Such as Shown in Fig. 3, the shape of groove 2a is rectangle；The shape of groove 2a may be the other shapes such as trapezoidal, not show in figure.

When utility model works, as shown in fig. 7, yarn 3 is controlled in the syringe needle of sley point after guide eyelit 2-1 Pass through on the inclined-plane 2c of bottom surface, avoids the syringe needle side that yarn 3 is slid onto sley point, effectively prevent dropped stitch.Equally, yarn 3 pass through on the groove 2a or horizontal plane 2b or inner sunken face 2d of the syringe needle bottom surface for being also controlled to sley point after guide eyelit 2-1 By, i.e., yarn 3 can only pass through below the syringe needle of sley point, yarn 3 will not band yarn in the syringe needle of groove pin 4, effectively prevent Dropped stitch.

By on probation, the processing is simple for the sley point of the utility model, and manufacturing cost is low, effectively prevents dropped stitch, significantly mentions The high reliability of band yarn, improves production efficiency and weaving quality, achieves good effect.
