Description
Technical field
The application relates to spinning-drafting technology, is specially the Rubber ring lower pin of drafting mechanism of spinning machine.
Background technology
The drafter of current cotton mill ring throstle, the two cushion rubber of general employing length, Spring Pendulum untie-sell, Spring cradle pressurizes, leaf spring cradle pressurization or Pneuamtic cradle pressue device, main dependence drawing rollers, rubber roll, cushion rubber, spring top pin and the acting in conjunction of curved surface ladder downside pin control fiber, realize drawing-off, cushion rubber, the middle additional friction force bound pair that the mechanism of spring top pin and curved surface ladder downside pin composition is formed controls fiber movement, ensure that the quality of drawing-off sliver has decisive role, especially cushion rubber, the front jaw of spring top pin and curved surface ladder downside pin composition, curved surface ladder downside pin is mainly supported lower cushion rubber and is guided the stable revolution of lower cushion rubber, support that upper pin makes it to be in technological requirement position simultaneously, downside pin is the state monopoly for marketing of one, six ingot, be fixed on roller stand, why be called that curved surface ladder downside pin is because its arbitrary cross-section is curved surface stairstepping, namely the upper surface of downside pin arbitrary cross-section is the red shape of combination that one section of straight line is connected with one section of curve, curved portion is higher than straight line portion, there is difference in height. formed stepped, straight line portion and curved portion all have certain thickness, curved surface stairstepping described in formation, the favourable sub-tensioning cushion rubber of this design, additional friction force circle in the middle of strengthening, improve the controlling extent to fiber, prisoner and being widely adopted, but research and experiment show further, the downside pin of this kind of shape well can not carry out strong control by drawing-off sliver fiber, there is the place had much room for improvement, its design defect is: straight line (plane) partial-length of downside pin is longer, the elastic acting force making it support apron is more weak, weaken the intensity of friction field in the middle part of main drawing area, enough not strong to the control of sliver, the uplift force of the peak of downside pin curved portion is also inadequate, the sliver curve drawing passage that apron is formed compares mitigation, sliver can not be controlled effectively, be unfavorable for the high-quality of resultant yarn.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the technical problem that the application will solve is the Rubber ring lower pin of a kind of improvement of bamboo product, and its counter extensioin sliver has better control, and yarn quality significantly improves, and structure is simple, wide adaptability.
The technical scheme that the application solve the technical problem is: design a kind of Rubber ring lower pin, its arbitrary cross-section shape is identical, basic is T font, and the upper surface of T font spread eagle part is the combined shaped that one section of straight line is connected with one section of allusion quotation line, curved portion is higher than straight line portion, have difference in height, straight line portion has a thickness, and the length of one section of described straight line portion is 4-4.9 millimeter; The length of the curved portion be connected with straight line portion is correspondingly 20-19.1 millimeter, and the distance of its peak distance straight line portion leading edge is 9-9.9 millimeter, and peak is correspondingly 15-14.1 millimeter apart from the distance C1 of apron lower pin tail end; The thickness of straight line portion is 2-5.3 millimeter, and the difference in height of curved portion and straight line portion is correspondingly 3.1-3.4 millimeter.
The length of described straight line portion is 4.2-4.5 millimeter; The length of the curved portion be connected with straight line portion is 19.8-19.5 millimeter accordingly, and the distance of its peak distance straight line portion leading edge is 9.5-9.9 millimeter, and peak is correspondingly 14.1-14.6 millimeter apart from the distance C1 of Rubber ring lower pin tail end; The thickness of straight line portion is 2.5-5 millimeter, and the difference in height of curved portion and straight line portion is 3.3 millimeters.
The length of described straight line portion is 4.5 millimeters; The length of the curved portion be connected with straight line portion is 19.5 millimeters accordingly, and the distance of its peak distance straight line portion leading edge is 9.9 millimeters, and peak is correspondingly 14.1 millimeters apart from the distance C1 of Rubber ring lower pin tail end; The thickness of straight line portion is 2.5 millimeters, and the difference in height of curved portion and straight line portion is 3.3 millimeters.
The application continues to have made Curve guide impeller mainly for the upper surface shape of Rubber ring lower pin, for different raw cotton, move forward the position of downside pin working face peak certain distance again, increase the length of curve (curved surface) part, correspondingly reduce the length of downside pin straight line portion (plane), strengthen to make the friction field near glue ring edge position, increase the difference in height of downside pin curved portion and straight line portion simultaneously, the application is in order to realize this idea, by straight length portion and lower straightway integral sinking corresponding with it, and the relative distance strengthened therebetween, with the upward pressure increasing rigidity and strengthen cushion rubber, further tensioning cushion rubber, enhancement curve drawing-off effect, the downside pin design of the application continues the control to fiber between reinforced upper and lower cushion rubber, make the distribution of draw zone internal friction circle more reasonable, reduce the length in district of swimming, the distribution of Fiber Velocity point in main drawing area is moved forward, jaw is concentrated forward further, and make the speed change history of fiber add stable, little same crystal seed be a large number of experiments show that (see embodiment) is when other conditions are constant, use the fine spining machine of the downside pin of this practicality newly plough invention obviously can improve evenness quality, sliver even thickness, slubbing, details obviously reduces, CV value reduces, the application owing to carrying out Curve guide impeller on existing downside pin and invention basis, only redesign the peak position of downside pin working face, the distribution of lengths of plane and curvature portion and the difference in height between them, other parts are not changed, therefore its structure is still simple, easy for installation, ring spun yarn type for present all use curved surface ladder downside pins can be suitable for, without the need to doing any change to the drawing-off part of fine spining machine, so have applicability and economy widely.
