Abstract

The utility model relates to the field of textile machinery, in particular to a needle cylinder for a cut loop knitting machine, which comprises a base body, a bearded needle and a cutting knife. An empiecement groove is arranged on the base body, and an empiecement is arranged in the empiecement groove. The needle cylinder for the cut loop knitting machine is characterized in that the end portion of the empiecement is not provided with an embedded portion connected with the base body so as to be in the shape of hanging in the air. Due to the fact that the end portion of the empiecement is in the shape of hanging in the air, the end portion of the empiecement can be bended elastically. A small gap is reserved between the bearded needle and the empiecement. When the bearded needle hooks yarns and returns back to an opening of the needle cylinder, the yarns are squeezed into the gap. Under the action of elastic recovery force of the end portion of the empiecement, the yarns are clamped by the empiecement and the bearded needle. At that moment, the cutting knife extends out to cut down the yarns to enable cut openings to be flat. The cut loop knitting machine has the advantages of being simple in structure, stable in working, flat in cut opening and the like.

Description

The cut velvet machine is used syringe

Technical field

The utility model relates to textile machine, and specifically reliable operation, cut velvet machine that result of use is good are used syringe.

Background technology

As everyone knows, the cut velvet machine is a kind of of weft-knitted garden machine, is the textile machine of producing lint class knitted fabric specially, and syringe is the core component of cut velvet machine; The structure of syringe is normally slotted on matrix, is bumped into empiecement in the groove, forms needle tray; To hold knitting needle, crochet hook and cutter, above-mentioned empiecement is when embedding matrix, and its total length all embeds in the groove of matrix; During use, when crochet hook hooked yarn and returns the syringe mouth, yarn was brought into the slit between crochet hook and the empiecement; Traditional method is the big slit of leaving between crochet hook and empiecement, and yarn can be free to slide in the slit, and the fiber of yarn is when cutting off; Order by the contact blade is successively cut off, but because yarn is not fixed, the tension force of the fiber of yarn when cutting is different; The fiber that the back is cut off receives the tension force of yarn and is extended before cutting off, the fracture of yarn is uneven after causing cutting off, and influences the whole structure of fabric.

Summary of the invention

The utility model proposes a kind of working stability to the deficiency that exists in the prior art, and the concordant cut velvet machine of yarn cutting back yarn fracture is used syringe.

The utility model can reach through following measure.

A kind of cut velvet machine is used syringe, comprises matrix, crochet hook and cutter, and matrix is provided with the empiecement groove; Empiecement is bumped in the empiecement groove; It is characterized in that the empiecement end is not connected with matrix is hanging shape, and empiecement can be stretched its end outside matrix, is not connected with matrix and is hanging shape to reach the empiecement end; Can also not establish the portion that is bumped into that is connected with matrix in the end of empiecement, be not connected and be hanging shape with matrix to reach the empiecement end.

The utility model is because the empiecement end is hanging shape, and the empiecement end can elastic bending, leaves less slit between crochet hook and the empiecement; When crochet hook hooked yarn and returns the syringe mouth, yarn was clamp-oned this slit, under the elastic-restoring force effect of empiecement end; Empiecement and crochet hook clamp yarn; Cutter stretched out yarn was cut off this moment, made the yarn fracture concordant, had advantages such as simple in structure, working stability, otch be smooth.

Description of drawings

Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 are the sketch map of different operating state.

Fig. 6 is a kind of cutaway view of A-A among Fig. 1.

Fig. 7 is the another kind of cutaway view of A-A among Fig. 1.

Mark among the figure: empiecement 1, crochet hook 2, cutter 3, yarn 4, matrix 5.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in the figure, a kind of cut velvet machine is used syringe, comprises matrix 5, crochet hook 2 and cutter 3; Matrix 5 is provided with the empiecement groove, and empiecement 1 is bumped in the empiecement groove, and the structure of above-mentioned each part is identical with connected mode and prior art; This does not give unnecessary details, and the utility model is characterised in that the end of empiecement 1 is not connected with matrix 5 and is hanging shape, and empiecement 1 can be as shown in Figure 6 be stretched in matrix 5 outsides its end to reach empiecement 1 end and is not connected with matrix 5 and is hanging shape; Also can not establish the portion that is bumped into that is connected with matrix 5 in the end at empiecement 1 as shown in Figure 7, be not connected with matrix 5 and be hanging shape with the end that reaches empiecement 1, the utility model is because the empiecement end is hanging shape; The empiecement end can elastic bending, leaves less slit between crochet hook and the empiecement, when crochet hook hooks yarn and returns the syringe mouth; Yarn is clamp-oned this slit, and under the elastic-restoring force effect of empiecement end, empiecement and crochet hook clamp yarn; Cutter stretched out yarn was cut off this moment, made the yarn fracture concordant, was shown in the following figure:

In accompanying drawing 1, crochet hook 2 does not collude gets yarn 4, and empiecement 1 does not produce strain.

In accompanying drawing 2, crochet hook 2 stretches out to collude gets yarn 4, and under the effect of yarn 4, crochet hook 2 ends are also tight naturally.It is big that gap between empiecement 1 and the crochet hook 2 becomes.

In accompanying drawing 3, crochet hook 2 colludes to be got yarn 4 and returns needle tray, and yarn 4 is brought in the slit.

In accompanying drawing 4, cutter 3 stretches out, and when blade did not contact yarn 4 as yet, cutter 3 tips strutted crochet hook 2 ends, and yarn 4 is squeezed in the slit, and squeezes the end of empiecement 1 curved to opposite side.Yarn 4 is clamped by empiecement 1 and crochet hook 2.

In accompanying drawing 5, cutter 3 continues to stretch out, and the yarn that has clamped 4 is cut off, and yarn 4 fractures are concordant.

Because empiecement 1 end is unsettled can strain, the yarn 4 of different thicknesses all can reliable grip, return the size that empiecement 1 distortion is regulated in position that needle tray is through adjustment crochet hook 2, thereby control clamp the size of yarn strength.
