Yarn passing structure of warp knitting machine

Technical Field

The invention relates to the field of warp knitting machines, in particular to a yarn passing structure of a warp knitting machine.

Background

In a warp knitting machine, a yarn guide structure is usually provided between a creel, a pan head and a main body of the warp knitting machine to prevent yarns from intertwining after being guided out of the creel or the pan head.

The yarn guide structure that has now usually comprises crossing yarn needle and guide yarn pole, and along with time lapse, yarn friction yarn divider needle can make the yarn divider needle wearing and tearing burr appear, and then the yarn appears the fluff when leading to crossing the yarn, hangs the yarn, the condition such as disconnected yarn for need often change the yarn divider needle, yarn divider needle life is short.

Disclosure of Invention

The invention provides a yarn passing structure of a warp knitting machine, and aims to solve the technical problems that the existing yarn guiding structure causes abrasion of a yarn dividing needle due to friction of the yarn on the yarn dividing needle along with the passage of time, the yarn is fluffed, hung and broken during yarn passing, the yarn dividing needle needs to be frequently replaced, and the service life of the yarn dividing needle is short.

A yarn passing structure of a warp knitting machine comprises a yarn guide rod, wherein the yarn guide rod is installed on the warp knitting machine through a small support plate, an angle aluminum is arranged on the side edge of the yarn guide rod, the angle aluminum is fixedly connected with the yarn guide rod through an angle aluminum gasket, a plurality of yarn dividing needles are fixedly installed at the upper end of the angle aluminum, a through hole through which the yarn guide rod can penetrate is formed in the upper end of the small support plate, the yarn guide rod can rotate in the through hole to drive the angle aluminum and the yarn dividing needles to rotate around the circle center of the yarn guide rod, the movement track of yarn is fixed during yarn guiding, and when the plurality of yarn dividing needles rotate around the circle center of the yarn guide rod, the contact position of the yarn and the yarn dividing needles is changed, so that the yarn can be located in various positions such as the inner part of the yarn dividing needles, the middle part of the yarn dividing needles and the outer part of the yarn dividing needles.

Furthermore, the yarn dividing needle is provided with a plurality of gaps through which yarns can pass, and one yarn is positioned in one gap of the yarn dividing needle during yarn passing, so that the yarns are prevented from being intertwined.

Furthermore, in order to realize that the yarn guide rod rotates to drive the yarn dividing needle to rotate, the angle aluminum is fixedly connected with the yarn dividing needle through a rivet, and the angle aluminum is fixedly connected with the yarn guide rod through the angle aluminum gasket.

Furthermore, the yarn guide rod is provided with a threaded hole at the joint of the angle aluminum gasket, the angle aluminum gasket is cylindrical, threads are arranged on the surface of the angle aluminum gasket, and the yarn guide rod is fixedly connected with the angle aluminum gasket through threads.

Furthermore, the lower end of the small supporting plate is provided with a fixing hole for installing the yarn passing structure on the warp knitting machine, and when the yarn passing structure is installed, the contact angle pressure of the yarn guide rod on the yarn can be changed by adjusting the installation angle of the small supporting plate and the warp knitting machine, so that the tension of the yarn is changed, and the tension control of the yarn is further realized.

Has the advantages that:

according to the yarn guide structure, the yarn guide rod is rotated to drive the yarn dividing needle on the angle aluminum to wind the center of the yarn guide rod, so that the contact position of the yarn and the yarn dividing needle is changed, the yarn can be in various position states such as the position close to the inside of the yarn dividing needle, the position close to the middle of the yarn dividing needle and the position close to the outside of the yarn dividing needle, when a certain position of the yarn dividing needle is abraded, the yarn guide rod can be rotated, the contact position of the yarn and the yarn dividing needle is changed, and therefore the problems that the yarn is abraded and burred by the yarn dividing needle along with the time lapse of the traditional yarn guide structure, the yarn is fluffed, hung and broken are caused, the service life of the yarn dividing needle is effectively prolonged, the installation structure is simple, the adjustment is convenient, and the yarn passing is stable;

the invention can also change the contact angle pressure of the yarn guide rod to the yarn by adjusting the installation angle of the small support plate and the warp knitting machine, further change the tension of the yarn and further realize the tension control of the yarn.
