Abstract
The utility model discloses a component which is specific used for a compact spinning frame. The shaped negative pressure pipe connector of compact spinning frame of the utility model mainly comprises a shaped negative pressure pipe, a little roller with teeth, and a gearwheel cover. The shaped negative pressure pipe is composed of a negative pressure pipeline, a semi-closed little roller mounting cavity, a transition gearwheel hanger, etc. The outer surface of the negative pressure pipeline and the outer surface of the mounting cavity are continuous and smooth. Through a bearing, the little roller with teeth is arranged in the shaped pipe little roller mounting cavity. The gearwheel cover is made into a corresponding irregular shape by transparent material. Depending on the positioning of the surrounding details, the whole connector is arranged on a roller base through the mounting face of the shaped pipe. The disassembly and assembly of the device is simple and reliable.
Description
Technical field
This utility model belongs to the special-purpose component of a kind of compact spinning machine.
Background technology
In traditional ring spinning yarn drafting system, the drafting force that gives draw zone is with the rove backtwisting, drawing-off through main drawing area, fibre bundle behind the backtwisting is pulled into the fibre bundle of certain width and fineness, cohesive force in this fibre bundle between the fiber is eliminated substantially, is complete loose condition (of surface) when fiber leaves front roller nip, forms a spinning triangular zone at front roller nip between the twisting point, fiber in this zone is controlled hardly, and the edge fiber can break away from main body and form flyings and filoplume.In twisting process, the fiber in this outside, zone is subjected to the longitudinal tension force maximum, and the middle suffered tension force of fiber is less, and the pretension that fiber is subjected in the resultant yarn of feasible twisting back is uniformity not, thereby causes the ultimate strength of yarn not reach due level.In order to solve of the influence of ring spinning trigonum to yarn quality, just produced the compact spinning technology, this technology is a controlling organization in the middle of the front roller nip of former ring throstle extremely increases between the twisting point, make fibre bundle in a single day leave compression and control that front roller nip just is subjected to negative-pressure air-flow, thereby reach the purpose of eliminating spinning triangular zone, obtain few, powerful high, the dried uniform spun yarn of bar of a kind of filoplume.Controlling organization mainly contains following several in the middle of existing: a kind of is to replace front roller with air-breathing roller with holes, negative-pressure air-flow is connected with air-breathing roller with holes by pipeline, air-flow from the hollow roller outside in small holes enters the roller cavity, fibre bundle is promptly adsorbed compression control by negative-pressure air-flow after the output of drawing-off upper leather roller jaw, under the effect of drawing roller, fibre bundle travels forward by air-breathing surface of roller linear velocity with holes.This controlling organization is had relatively high expectations to air-breathing roller material with holes, and surface smoothness and hardness etc. are strict, and manufacturing cost is higher, and can not integral disassembly, assembly, safeguards inconvenient.Second kind of controlling organization is to increase special-shaped negative pressure straw and draw upper leather roller at spinning triangular zone, drawing-off anterior epithelium cornea roller drives by travelling gear and draws the upper leather roller rotation, fiber is after front roller nip output, draw top roller and Special-shaped suction pipe and form the control zone, have the bar shaped suction inlet on the Special-shaped suction pipe, cover with the porous circle on it, the porous circle rotates under the friction of drawing upper leather roller.This controlling organization can integral disassembly, assembly, but because anterior epithelium cornea roller and draw roller and belong to Passive part in nature rotating rotates if drive the porous circle by them, its rotational stability directly influences yarn qualities.
The utility model content
The purpose of this utility model proposes in order to address the above problem exactly.Change the planform of special-shaped negative pressure pipe, increase a semi-open type cavity and a gear suspension bracket, in this cavity, place the little roller of a band tooth, and change the drawing-off front roller into band tooth roller, one nylon gear is installed on special-shaped negative pressure straw gear suspension bracket then, and nylon gear draws gears engaged with drawing-off front roller gear, band tooth small gross simultaneously.The negative-pressure air-flow of abnormity negative pressure pipe is controlled the fibre bundle that breaks away from behind the front roller nip by being enclosed within porous circle on the suction pipe and suction pipe suction inlet.The porous circle little roller and draw the drive of roller and rubbing action under actively, initiatively according to certain linear velocity revolution.For the flyings that prevent the workshop, dust etc. are collected at the stability that influence is rotated on the travelling gear, a transparent gear wheels case is installed on special-shaped negative pressure suction tube, can prevent dust, also can observe the operation conditions of gear at any time.
Be described further below in conjunction with the structure and the implementation method of accompanying drawing this utility model.

1. roller stands among the figure, 2. special-shaped negative pressure pipe, the 3. little roller of band tooth, 4. nylon gear, 5. gear house, 6. special-shaped negative pressure pipe end-cap, 7. apron lower pin, 8. be with the tooth front roller, 2.1. the negative pressure pipe, 2.2. negative pressure pipe suction inlet, 2.3. aspiration channel interface, 2.4. the gear suspension bracket, 2.5. band tooth small gross draws the installation cavity.
The specific embodiment
Planform such as Fig. 4, shown in Figure 5 of abnormity negative pressure pipe, it draws installation cavity 2.5 to form by negative pressure pipe 2.1, negative pressure pipe suction inlet 2.2, aspiration channel interface 2.3, gear suspension bracket 2.4 and band tooth small gross.Cavity 2.5 is semi-enclosed cylinder, and after band tooth small gross drew 3 to put into wherein, each was fixed in two ends in the cavity with a rolling bearing, has guaranteed that small gross draws the flexibility of rotation.Chamber outer surface and negative-pressure pipeline outer surface require smooth continuously, and lucky and little surface of roller was tangent after the size of cavity breach can guarantee on the porous snare.Size, the shape of negative pressure pipe suction inlet 2.2 are decided according to the spinning process demand.Aspiration channel interface 2.3 and negative-pressure pipeline 2.1 communicate, and during work, under the effect of axial flow blower, air-flow enters negative-pressure pipeline 2.1 from the micropore of porous circle through negative pressure pipe suction inlet 2.2, enters main air duct through aspiration channel interface 2.3 then.The position of gear suspension bracket 2.4 must guarantee nylon gear install after can and drawing-off front roller gear, small gross draw the gear correct engagement.
Abnormity negative pressure pipe installation site, duty such as Fig. 1, Fig. 2, shown in Figure 3 are placed on roller stand 1 fixed position with installing, debug complete special-shaped negative pressure pipe assembly, and be with special-shaped negative pressure pipe end-cap 6 that its edge is tight then.Draw 3 for the flyings that prevent the workshop, dust etc. are collected at band tooth small gross, on the gear parts and nylon gear 4 of band tooth front roller 8, with a transparent gear house 5 with its covering, open a circular hole on 5, its size just can be from air intake duct interface cover down, the upper end fork-shaped abuts against on the apron lower pin 7 then, and the lower end arc surface is embraced at the special pipe small gross and drawn on the outer surface that cavity is installed.
This special pipe conjunction can integral disassembly, assembly, and method is simple and reliable, and the motion of porous circle is more stable, and is less to the yarn quality influence.
