Referring to shown in Figure 6, wherein a kind of yarn feeder for the prior art use, its structure is roughly and is provided with drive unit 51 and yarn feeding wheel 52 on a body 50, and be provided with at one end and send creel 53 and Yarn Brake 54, this Yarn Brake 54 is provided with support 57, on support 57, be arranged with two brake hoop 55 and springs 56 arranged side by side, the aperture of this two brake hoop 55 is slightly larger than the external diameter of support 57 and is subjected to spring 56 and replaces and be and recline mutually, and the pass of brake hoop 55 cooperates the external form of support 57, deliver to by the coil of wire when yarn and enter behind the lead ring of creel 53 between two brake hoops 55 arranged side by side, yarn was subjected to the clamping of two brake hoops, 55 certain strength and had tension force this moment, so that the manufacturing of knitting of knitting machine to be provided.

The another kind of yarn feeder of prior art, as shown in Figure 7, wherein yarn through on the body 60 set send creel 61 after, after moving to loom, yarn feeding wheel and other lead ring knit manufacturing by brake lever 62 turnovers, aforementioned both sides at brake lever 62 are provided with many guide rods 63 with the restriction yarn, because yarn is the rod member by a brake lever 62 only, problem such as cause that the not enough and tension force that produced of formed tension force can't be stablized.

Because the line of each yarns footpath and intensity thereof are all less; when yarn during at the yarn feeder by aforementioned prior art; often because the undesirable yarn that makes of the structure of yarn feeder has tension force situation uneven or broken string to produce; after broken string is shut down; operating personnel must handle and just can proceed cloth again after the broken string problem and knit system; this kind broken string will cause the reduction of producing interruption and production efficiency as if frequent generation, and then cause the problems such as increase of production cost.

The utility model content

In view of the employed yarn feeder of prior art, when yarn passes through yarn feeder, easily cause yarn because of problems such as easy broken strings that strain problem produces, the utility model redesigns its structure, its yarn that transmits is had the stable tension force except keeping, and yarn is difficult for broken string in moving.

In order to reach aforesaid purpose, the utility model provides a kind of knitting machine yarn feeder structural improvement, and it is provided with a body, described body is provided with drive unit and yarn feeding wheel, be provided with Yarn Brake and two brake hoops at body one end and adjacent to drive unit and yarn feeding wheel place, wherein

Described Yarn Brake has a carriage, is provided with two lever jacks in a side of carriage, described two lever jacks at interval be arranged at top and place, below; Described two brake hoops, its opposite flank is a pressure surface, and is provided with perforation, described piercing aperture is greater than the distance between two lever jacks, and has magnet assembly on two brake hoops and can make and form a suction between two brake hoops.

Described knitting machine yarn feeder structural improvement, wherein the lever jack that is positioned at lower position in two lever jacks is provided with catch in the end.

Described knitting machine yarn feeder structural improvement wherein is provided with a bearing on carriage, described bearing is provided with the bar hole at two intervals, and described two lever jacks, one end is fixed on the bar hole, the connection bearing of trend of two lever jacks with laterally be formed with an angle.

Described knitting machine yarn feeder structural improvement, wherein said carriage is one to have the housing of a lateral plate, an egative film and a dististyle, described dististyle is connected with body, on described egative film, be provided with a yarn guiding ring, be provided with a fixing hole on lateral plate, it is fixing that described fixing hole cooperates a fixture and bearing to mutually combine.

By the aforementioned techniques means, the utility model is because two brake hoops that can adsorb mutually, be set on two lever jacks and be support with the set perforation in its center with the lever jack that is positioned at the top, the aperture of described perforation is greater than the distance of two lever jacks, make brake hoop can be very flexibly on two lever jacks according to yarn pass through rotate, and can make yarn have stable tension, and then can reduce the broken string generation of yarn, to reduce the cost of handling broken string and to enhance productivity.

The specific embodiment

Referring to shown in Figure 1, be the designed knitting machine yarn feeder structural improvement of the utility model, this yarn feeder is arranged on the knitting machine, when weaving operation, yarn on each coil of wire enters the yarn device through the guiding of each lead ring, and the yarn by the yarn device can be formed with certain and stable tension and enter knitting mechanism to carry out the system of knitting of fabric.

Yarn feeder shown in the figure, it has a body 10, body 10 is provided with a drive unit 20, and thereunder be provided with a yarn feeding wheel 21, in addition on body 10, be provided with one and upright advance creel 11 adjacent to drive unit 20, be formed with at the upper and lower end place of advancing creel 11 and can below body 10 and adjacent to yarn feeding wheel 21, be provided with guide rod 101,102 and ring 103, be provided with a Yarn Brake 30 and two brake hoops 40 at an end of aforesaid body 10 for ring 111,112 in order to the guiding yarn.

Cooperation is referring to Fig. 2, Fig. 3 and shown in Figure 4, Yarn Brake 30 has a carriage 31, a bearing 32 and two lever jacks 33, wherein carriage 31 can be designed to have a lateral plate, the housing of an egative film, a top sheet and a back dististyle, be provided with a canaliculate guide sheet 301 in the sheet place projection of housing top, be connected with body 10 with dististyle thereafter, on egative film, be provided with a yarn guiding ring 311, and on lateral plate, be provided with a fixing hole 312;

Bearing 32 can be relative with fixing hole 312 and gives in conjunction with fixing with a fixture, on bearing 32, be provided with two mutual bar holes 321 at interval, two lever jacks 33 can be separately fixed on the bar hole 321 and the connection bearing of trend of two set lever jacks 33 and the horizontal angle that forms, a feasible wherein lever jack 33 is positioned at lower position and its rod end is provided with a catch 331, and another lever jack 33 that is not provided with catch 331 is positioned at the top position;

This brake hoop 40, it is the ring body that a center has
