The utility model adopted has simple structure, convenient dismantling and assembling, easy use and good fastening effect.
Description
(1) technical field
The utility model is that a kind of parts of cotton spinning drawing frame improve structure, particularly relates on a kind of cotton spinning drawing frame the structure that is in transmission connection such as roller, roller rotating shaft.
(2) background technology
Known, a kind of important equipment is the cotton spinning drawing frame in the textile machine, and the function of drawing frame is the spinning machine that the ribbon after some combings or the combing is processed into the ribbon with certain quality requirements.The effect of drawing frame is an internal structure of improving strip, thereby improves its long segment uniformity, reduces weight unevenness simultaneously, make the straightening of fibers in the strip parallel, reduce crotch, make fineness up to specification, make the raw material of variety classes or different qualities evenly mixed, reach the mixing ratio of regulation.
That the cotton spinning drawing frame has is simple eye, two, four eyed etc. are multiple.The feeding of many one threads, through and close, make after the drawing-off title single-head draw frame of an one thread; Export two drawing frames of title of two one threads, surplus and the like.Every drawing frame has independent transmission system.Drawing frame is made up of feeding part, drawing-off part, slivering part and some automatics etc.
Feeding part is formed by feeding bar tube, conducting bar roller, sliver pressure roller, sliver platform (or overhead) with to cotton roller etc.Sliver is drawn in feeding bar tube by conducting bar roller and sliver pressure roller, serves the sliver platform by certain orientation.On High-speed Drawing Frame, the position of conducting bar roller nestles up feeding bar tube, the sliver drawing to platform, again by sending into drafter to cotton roller.The feeding of this active type can be avoided the sliver disorder of drawing, and reduces unexpected elongation.
The drawing-off part is made up of drafter and automatic cleaning apparatus etc.The pattern of drafter has multiple, depends mainly on the compound mode and the additional control parts of drawing rollers.The compound mode of drawing rollers has three kinds up and down, promptly one on the other on (bottom roll of a roller), one on two times (two bottom rolls of a big roller) and two once (bottom roll of two rollers).If each compound mode to roller all is one on the other, clamping yarn in same plane promptly is called the straight line drawing-off, if wherein there is part to belong on one on two times or two once compound mode, just is called curve drawing, as four mo(u)ld bottom halves on three etc.The curved shape of yarn has produced additional drawing frictional force during because of drawing-off, has improved the control to fiber movement.
On drawing frame, feeding strip radical is many, and each is much bigger to the pressurization that adds pressure ratio Speed frames and fine spining machine of roller.For High-speed Drawing Frame, whether amount of pressurization is fully with stable, particularly important.
The effect of cleaning device is in time to remove flyings and the dirt bits that attach on roller and surface of roller, prevents to gather the sliver that falls in heaps and forms the yarn defect, and this is particularly important for High-speed Drawing Frame.
Slivering partly comprises boundling mechanism, horn mouth, presses roller, encloses bar dish, sliver can chassis etc.Boundling mechanism is made up of buncher, boundling roller, curved catheter etc.Buncher be metal inlet big, go out young novel collector, be packed in the front of front draft roller, web in time be gathered into band shape, prevent limit fiber when web is exported at a high speed scatter and disappear and chaotic, increase interfibrous cohesive force, reduce and twine roller and disconnected bar phenomenon.The effect of boundling roller is the compression cotton band, the degree of stretching of stable fibers.Curved catheter is a semiclosed or enclosed copper conduit, and the cotton band is successfully imported horn mouth, prevents cotton band broken end or stops up horn mouth.Horn mouth is that the cotton band is pressed into tight and smooth strip with the effect of pressing roller, makes strip reduce unexpected elongation when drawing, and increases the capacity of sliver can.Strip through pressing the roller compression enters the tube gear of can coiler, enspheres in the sliver can with cycloid shape.In order to adapt to the processing of chemical fibre raw material, the circle bar dish of spirality space curve inclined tube is partly adopted in slivering, can prevent to stop up circle of inclined tube.
On the cotton spinning drawing frame, be equipped with such as roller, many specifications of the multiple model of roller rotating shaft, be used to connect belt wheel, the various power of transmission, because the rotating shaft rotary speed is very fast, bear certain load again, frequent generation and belt wheel is loosening in using practice, transmit unreliable phenomenon, the too numerous and diverse again trouble of the device of some is given the running precision of complete machine and is brought influence service life.Therefore, pressing for provides a kind of rotating shaft of improvement assembly structure, with assembling and the reliable transmission that increases it.
(3) summary of the invention
The purpose of this utility model is to intend providing a kind of Axile connection structure that increases assembling convenience and reliable transmission.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rotating shaft syndeton of cotton spinning drawing frame, comprise rotating shaft, the screw and the belt wheel of head band groove, it is characterized in that: form a bottom major diameter has step less than the rotating shaft diameter diminished shaft at the rotating shaft axle head, on diminished shaft, be nested with two semicircular taper sheaths, the end face of taper sheath is offered semicircular screw hole, the conical surface of taper sheath and diminished shaft cone match, the height of taper sheath is greater than the length of diminished shaft, the screw hole of taper sheath end face is embedded in the groove of screw, the axis hole of belt wheel is nested with two semicircular taper sheath outer rings, and screw passes the tapered shaft end that taper sheath end face screw hole is tightened on rotating shaft.
Further, described two semicircular taper sheath conical surface major diameters are 2 to 4 millimeters less than the major diameter value of the diminished shaft of rotating shaft.
Further, the tapering of described diminished shaft is 1: 10.
Adopt the technical program, two semicircle taper sheaths are nested with on the multidiameter of rotating shaft, the outer ring of taper sheath is nested with the axis hole of belt wheel, screw passes the screw hole on the little bottom surface of taper sheath, be tightened on the axle head of multidiameter, because the height of taper sheath is less than the length of multidiameter, when tightening screw, the handle face screw hole edge of compressing taper sheath moves axially, the step that the big mouth of taper sheath props up multidiameter cannot moves, and taper sheath is had to bulge in the axis hole of belt wheel and, thus, be connected cooperation between fastening rotating shaft and belt wheel, can not produce mutual rotation again, the effect of tensioner belt wheel is played in slippage, because its structure adopts two or many conical surface contacts, expanding force is big, balance is good, therefore is the optimum structure that cotton spinning and Shu bar machine high speed rotating part connect.When the screw reverse rotation, nut head or screw shoulder belt the two halves conical sleeve and are moved in the other direction toward axle, play the effect of unclamping belt wheel.
Superiority of the present utility model and beneficial effect adopt the utility model simple in structure, and easy accessibility uses easily, and is fastening effective.
