Abstract

The utility model relates to textile industry and provides a meshed ring used with compact spinning device in ring spinning frame, in particular a novel yarn-compacting meshed ring used with compact spinning device in ring spinning frame. The meshed ring has a special fabric structure in which the warp cross number is less than the weft cross number. The weft density is larger than the warp density, the tensile strength is increased and the elongation is increased. The warp and weft are made of monofilaments with different rigidity, so that the rigidity in the width direction is improved to ensure the transmission more reliable; the flexibility in the circumferential direction is improved to reduce the transmission resistance and ensure the meshed ring to run stably. The mesh openings are different in size and distributed uniformly, are conducted in rectangular, trapezoid or other non-square shapes, have less air resistance to increase the air flow, and help to remove dust particles.

Description

New structure boundling net circle

Affiliated technical field

The purpose of this utility model provides the good new structure boundling net circle of a kind of transmission performance, be applied to textile industry ring spinning frame " airflow " gather spin (closely spinning) device.

Background technology

At present gathering a kind of " net circle (or claiming grid ring) " that spinning equipment uses at ring throstle air-flow beaming type, is use the Polymer Synthesizing fibre single thread, with the tubular circle of woven method manufacturing.

As shown in Figure 1, net circle 1 is enclosed within on the negative pressure pipe 2, through last pressure roller 4, driving element 5 and transmission pinch roller 6 frictional drive, makes itself and front roller 3 that direction unanimity, big or small identical linear velocity be arranged by front roller 3.Its effect is the air-flow 7 by the negative pressure generation of negative pressure pipe 2, to be adsorbed on the surface of net circle 1 from the fleeces bar 0 that the jaw of front roller 3 and last pressure roller 4 is exported, net circle 1 is with the identical linear velocity advanced in unison of front roller 3, because the effect of air-flow 7, make wadding bar 0 cross-direction shrinkage, thereby spun yarn evenness is good, filoplume is few, intensity is high.

The net circle of conventional art as shown in Figure 2, warp 01 (width 8) and parallel 02 (circumferencial direction 9) are used with a kind of synthetic fiber monofilament and are made; The density (at interval) of adjacent warp 01 and parallel 02 is identical; Institutional framework is generally on two twill elementary organization once.There is following shortcoming in this net circle:

1. owing to the difficulty of weaving, main stressed parallel (circumferential 9) density of net circle can't increase near the limit again, and the work TENSILE STRENGTH is not high, and tensible rigidity is little.

2. because warp 01 density is bigger than normal, cause circumferential skewing rigidity big, and influenced the transmission performance of net circle.

3. because mesh all is the identical square of size, staple fibre and dust stop up mesh easily.

Summary of the invention

A kind of new structure boundling net circle that the utility model provides its objective is to reduce net circle bending stiffness, reduces the transmission resistance, improves tensible rigidity.Concrete grammar is as shown in Figure 3:

1) fabric structure of new construction boundling net circle adopts the different particular fabric institutional framework of longitude and latitude crossing number, and be characterized in: when each root parallel 04 inweaved, warp 03 crossing number lacked than parallel 04 crossing number, helps the broadwise line density and improves.

2) new construction boundling net circle warp density reduces, and weft density strengthens, and weft density is greater than warp density.

3) warp 03 of new construction boundling net circle width 8 adopts the big thick monofilament of bending stiffness; The parallel 04 of circumferencial direction 9 adopts the little thin monofilament of bending stiffness, and circumferential tension rigidity is big, and bending stiffness is little.

4) the above-mentioned particular tissues structure of new construction boundling net circle makes mesh shape non-square, but the rectangle that varies in size, is evenly distributed, trapezoidal or other shapes.

New construction boundling net circle of the present utility model has following advantage:

1) new construction boundling net circle increases weft density, and net circle parallel 04 quantity of same width increases, and intensity increases and elongation reduces.

2) new construction boundling net circle reduces warp 03 density, and helping parallel 04 quantity increases, and has reduced circumferential skewing rigidity simultaneously.

3) the particular fabric structure of new construction boundling net circle employing can form the mesh that varies in size, and macropore is little to air drag, and air velocity is fast, and dust granule passes through in macropore easily, reduces the phenomenon that dust stops up mesh.

The specific embodiment

Warp-wise adopts different monofilament with broadwise, and organizine is slightly thick, and the bending stiffness of net circle width is big, is difficult for fold takes place, and it is stable to help transmission; Tram is than the fine filling silk, and circumferentially rigidity is little.

Reduce warp density, can increase weft density.Increase in same width equator quantity, the operative orientation (circumferentially) of net circle has increased TENSILE STRENGTH and tensible rigidity;

Warp density is little, has reduced the circumferential skewing rigidity of net circle, reduces net circle transmission resistance, has improved net circle transmission performance.

Adopt special weave structure; Can form the mesh that shape is different and vary in size, macropore is little to air drag, and air velocity is fast, and dust granule passes through in macropore easily, reduces the phenomenon that dust stops up mesh.
