Abstract

The utility model relates to a rotary yarn guide roller type warp knitting machine, comprising: a frame; the supporting beam is fixedly connected with the rack and is suitable for supporting the rotatably unreeled yarn roll; the brackets are symmetrically fixed on the rack; the two ends of the yarn guide roller are respectively and rotatably connected with the corresponding brackets; the connecting rod is horizontally arranged and positioned below the yarn guide roller, and two ends of the connecting rod are fixedly connected with the corresponding supports; the yarn dividing needle is horizontally arranged on the connecting rod; because the live-rollers rotates the setting, consequently the frictional force of yarn and live-rollers can turn into the turning force of live-rollers, compares in traditional line contact friction, and this scheme has reduced the frictional force between yarn and the live-rollers, and then has reduced the production of yarn static, prevents to take place the condition appearance of hank yarn.

Description

Rotary yarn guide roller type warp knitting machine

Technical Field

The utility model relates to a warp knitting machine, in particular to a rotary yarn guide roller type warp knitting machine.

Background

The warp knitting machine is a machine which uses one group or a plurality of groups of yarns which are arranged in parallel to form knitted fabrics on all working needles of a warp feeding machine by means of loop forming; the double-needle bar warp knitting machine is an important machine type for efficiently producing interval fabrics and velvet fabrics.

In traditional tricot machine, the yarn guide roller is fixed setting, and the minute needle is fixed on the yarn guide roller, and like this, the yarn can carry out line contact with the wire guide roller at the in-process that unreels at a high speed to lead to the yarn to produce static because of the friction, and then the condition of hank appears.

In summary, how to reduce the friction between the yarn and the yarn guide roller is a problem that researchers in the field are in urgent need to solve.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: how to reduce the friction between the yarn and the guide roller;

in order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model is a rotary yarn guide roller type warp knitting machine, comprising: a frame; the supporting beam is fixedly connected with the rack and is suitable for supporting the rotatably unreeled yarn roll; the brackets are symmetrically fixed on the rack; the two ends of the yarn guide roller are respectively and rotatably connected with the corresponding brackets; the connecting rod is horizontally arranged and positioned below the yarn guide roller, and two ends of the connecting rod are fixedly connected with the corresponding supports; the yarn dividing needle is horizontally arranged on the connecting rod;

in this scheme, the live-rollers rotates the setting on the support, the yarn dividing needle passes through the connecting rod to be fixed on the support, and be located the below of live-rollers, the yarn that emits from the yarn book passes through the live-rollers in proper order, the yarn dividing needle, because the live-rollers rotates the setting, consequently the yarn can turn into the turning force of live-rollers with the frictional force of live-rollers, compare in traditional line contact friction, this scheme has reduced the frictional force between yarn and the live-rollers, and then has reduced the production of yarn static, the condition that prevents to take place the hank appears.

How to realize the rotary connection of the bracket and the yarn guide roller, the utility model adopts the technical scheme that both ends of the yarn guide roller are fixedly connected with the bracket through bearings;

both ends of the yarn guide roller are fixed with bearings, and the yarn guide roller is rotatably connected with the bracket through the bearings, so that the yarn guide roller can rotate relative to the bracket.

How to limit the axial movement of the yarn guide roller arranged on the bracket, the utility model adopts the structure that the yarn guide roller is fixed with a limiting ring which is propped against the end surface of the inner ring of the bearing;

in the scheme, the bearing outer ring is fixedly connected with the support, so that the fixed connection between the yarn guide roller and the bearing inner ring is only required to be ensured, the limiting ring in the scheme is sleeved on the yarn guide roller and abuts against the corresponding bearing inner ring through the two limiting rings, and the axial movement of the yarn guide roller arranged on the support is limited.

How to fix the spacing ring on the yarn guide roller, the utility model adopts the groove for placing the spacing ring at both ends of the yarn guide roller;

the spacing ring is arranged in the groove, so that the spacing ring and the groove are interlocked, and the spacing ring can be sleeved on the yarn guide roller.

The utility model has the beneficial effects that: the utility model relates to a rotary yarn guide roller type warp knitting machine, wherein a rotating roller is rotatably arranged, so that the friction force between yarns and the rotating roller can be converted into the rotating force of the rotating roller.
