Abstract

The utility model discloses a yarn feeding apparatus reducing yarn wear. The yarn feeding apparatus is formed by a yarn feeding body, a yarn entering seat, an adjusting wheel assembly, a yarn guiding wheel assembly, a yarn passing plate, a rotating shaft and yarn dividers, wherein the yarn guiding wheel assembly is provided with at least one yarn guiding wheel; each yarn guiding wheel is provided with a wheel disc and a plurality of guide columns; the plurality of guide columns are evenly inserted between two disc sheets the rotating disc along a rotating disc groove at intervals to form a round side wall of the rotating disc; each guide column forms an arc-shaped guide surface for yarn guiding; and a curvature radius of the arc-shaped guide surface is equal to the radius of the round side wall formed by the plurality of guide columns. Compared with the prior art, a contact area between yarns and the guide columns can be greatly improved, so wear degree of the yarns is largely reduced and yarn quality is ensured.

Description

A kind of yarn-feeding device that reduces thread wear

Technical field

The utility model relates to spinning equipment field, particularly a kind of yarn-feeding device that reduces thread wear.

Background technology

Yarn feeding wheel device is as the critical piece of circular disc knitting machine or computer jacquard knitting machine yarn-feeding device, and it is beneficial to the making of follow-up cloth for delivery of yarn.

The applicant once applied for and had obtained Chinese patent ZL201120152680.0, and it relates to a kind of structure-improved of yarn feeding wheel, the many porcelain bars that yarn guiding wheel wherein has wheel disc and is made up of ceramic material; Many porcelain bars are evenly located in along wheel disc dish groove between two discs of wheel disc and form trying to get to the heart of a matter of wheel disc dish groove, and yarn is wrapped on trying to get to the heart of a matter of being made up of many porcelain bars.

But, because above-mentioned many porcelain bars are all cylinders, because the volume of yarn guiding wheel itself is limited, the diameter of these many porcelain bars is all less, so make the radius of curvature of porcelain rod outer surface less, so make the real contact area of yarn and porcelain bar very little, thereby there is the defect that thread wear is larger.

In view of this, the inventor, for above-mentioned defect further investigation of the prior art, has this case to produce then.

Utility model content

The purpose of this utility model is to provide a kind of yarn-feeding device that reduces thread wear, has to solve prior art the problem that thread wear is larger.

In order to reach above-mentioned purpose, solution of the present utility model is:

By body, enter yarn seat, regulating wheel assembly, yarn guiding wheel assembly, cross yarn plate, rotating shaft and spreader and form, this yarn guiding wheel assembly has at least 1 yarn guiding wheel, each yarn guiding wheel all has wheel disc and some guide pillars, these some guide pillars along wheel disc dish groove evenly, compartment of terrain is located between two discs of wheel disc and forms the circular side wall of wheel disc, each root guide pillar is all formed with the arc guide face for guide, and the radius of curvature of this arc guide face is more than or equal to the radius of the wheel disc circular side wall being surrounded by some guide pillars.

Adopt after said structure, a kind of yarn-feeding device that reduces thread wear that the utility model relates to, because the radius of curvature of the arc guide face on each root guide pillar all matches with the radius of the wheel disc circular side wall being surrounded by above-mentioned guide pillar, so in the time that yarn is wound around, compared with prior art, can greatly promote the contact area between yarn and guide pillar, thereby greatly reduce the degree of wear of yarn, guarantee the quality of yarn.

Detailed description of the invention

In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.

As depicted in figs. 1 and 2, a kind of yarn-feeding device that reduces thread wear that the utility model relates to, by body 1, enter yarn seat 2, regulating wheel assembly 3, yarn guiding wheel assembly 4, cross yarn plate 5, rotating shaft 6 and spreader 7 form, this yarn guiding wheel assembly 4 has at least two yarn guiding wheel 41(for automatic color-changing yarn-feeding device, but for monochromatic yarn-feeding device, a yarn guiding wheel 41 is only set), each yarn guiding wheel 41 all has wheel disc 411 and some guide pillars 412, it is even that these some guide pillars 412 coil groove along wheel disc 411, compartment of terrain is located between two discs of wheel disc 411 and forms the circular side wall of wheel disc, above-mentioned feature and existing automatic color-changing yarn-feeding device are basic identical, therefore be not described in detail.

Improvement of the present utility model is, each root guide pillar 412 is all formed with the arc guide face 413 for guide, and the radius of curvature of this arc guide face 413 equals the radius of wheel disc circular side wall.So, in the time that yarn is wound around, compared with prior art, can greatly increases the contact area between yarn and guide pillar 412, thereby greatly reduce the degree of wear of yarn, guarantee the quality of yarn.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.

Claims

1. one kind is reduced the yarn-feeding device of thread wear, by body, enter yarn seat, regulating wheel assembly, yarn guiding wheel assembly, cross yarn plate, rotating shaft and spreader and form, this yarn guiding wheel assembly has at least 1 yarn guiding wheel, each yarn guiding wheel all has wheel disc and some guide pillars, these some guide pillars along wheel disc dish groove evenly, compartment of terrain is located between two discs of wheel disc and forms the circular side wall of wheel disc, it is characterized in that: each root guide pillar is all formed with the arc guide face for guide.

2. a kind of yarn-feeding device that reduces thread wear according to claim 1, is characterized in that: the radius of curvature of described arc guide face equals the radius by the circular side wall of wheel disc that some guide pillars form.
