The utility model discloses an ingot suspension structure for improving and controlling the unwinding tension of an ingot suspension, which comprises a suspension ingot main body, an ingot suspension cap, and an ingot suspension screw rod. The ingot suspension cap has an inner ingot suspension sleeve, which is set in the axial direction of the tail of the ingot suspension rod. The ball holder and the cage make the balls evenly distributed between the ball holder and the inner sleeve of the spindle, and a damping ring in sliding contact is installed above the inner sleeve of the spindle, and a damping ring is installed between the top outside of the damping ring and the inside of the top of the spindle cap. The spring and the damping spring are fitted with a spindle cap, and the contact area between the spindle screw and the damping ring is provided with a thickened area, and two symmetrical planes are processed in the thickened area, and the round hole in the middle of the damping ring is set as an oblate hole. The beneficial effects are: as the weight of the roving constantly changes during spinning, the unwinding tension can be controlled to the greatest extent, preventing end breakage and falling during the unwinding process; the hanging spindle screw and the damping ring are relatively fixed, avoiding It turns out that the damping ring overcomes the spring force and rotates with the spindle sleeve because of excessive friction.
Description
Technical field
The utility model relates to field of textile machinery, and the improvement in the raw material series fine spining machine parts that especially cotton spinning, bast fibre spinning, silk spinning, wool spinning, chemical fibre spin controls the lift spindle structure of lift spindle unwinding tension.
Background technology
Will arrive spinning process again through Roving Frames in fabrication processes, in Roving Frames, spun rove is wrapped on flyer bobbin, is then installed to by flyer bobbin and is arranged on the lift spindle of fine spining machine, then rove is drawn into fine spining machine carry out next step processing.Along with the running of fine spining machine, rove is constantly pulled from flyer bobbin and enters fine spining machine.Lift spindle rotates to yarn direction under the effect of unwinding tension in this course, rove is made at the uniform velocity to enter fine spining machine, therefore lift spindle is needed to have good unwinding tension response characteristic, in order to make the speed of traction even, the primary structure of current lift spindle is outer cover, damping spring, damped ring, the structure that lift spindle cover and steel ball bowl are connected in series by suspension rod bolt, in this structure, damped ring is directly enclosed within suspension rod bolt to make it be fitted on lift spindle cover to provide unwinding tension by damping spring by elasticity, but lift spindle frictional force is affected by gravity, when rove gravity is large, then the large unwinding tension of frictional force is also large, unwinding tension is also by the impact of unwinding arm of force change, and during flyer bobbin full yarn, the unwinding arm of force is maximum, and at this moment unwinding tension trend reduces.Both on draw yarn tension to affect direction contrary, after comprehensive, larger influence factor is gravity.When on flyer bobbin around full rove time, the gravity that lift spindle bears is maximum, frictional force is maximum, during traction rove, in operation process, damped ring inevitably overcomes spring force sometimes and follows lift spindle cover to rotate together because frictional force is excessive, cause unwinding tension irregular and the elongation also harmful drafting that meets accident, add the manipulation strength of spinner, and affect spinning quality; When being wrapped in the rove on flyer bobbin and reducing gradually, frictional force also reduces, and under the traction of equal tractive force, sliver easily drops, and now flyer bobbin stops operating.Along with the carrying out of unwinding action, cause unexpected little micro-joint drawing-off when spool after the length ruing out of tenesmus rotates suddenly (unwinding tension is now maximum), form the long snick yarn defect of spun yarn.
Utility model content
The purpose of this utility model for provide a kind of structure simple, automatically can control the lift spindle structure that unwinding tension is steady state value, the improvement eliminating broken end and falling phenomenon controls lift spindle unwinding tension, to overcome the object of the defect of the prior art that background technology is mentioned.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of lift spindle structure improving control lift spindle unwinding tension, there is lift spindle main body and lift spindle cap, lift spindle screw rod is fixed with at the axis direction of lift spindle cap, lift spindle screw head is in outside lift spindle cap, lift spindle screw rod tail is in inside lift spindle cap, there is in lift spindle cap lift spindle inner sleeve, lift spindle inner sleeve is fixedly connected with by pin with lift spindle main body, in the holder of lift spindle screw rod tail axis direction suit ball, retainer makes ball be evenly distributed between ball holder and lift spindle inner sleeve, the damped ring slidingly contacted is housed above lift spindle inner sleeve, damping spring is set with between damped ring top outer and lift spindle cap inside top, lift spindle cap is set with above damping spring, described lift spindle screw rod and damped ring contact area are provided with and increase thick region, increase thick region processing and go out two symmetrical planes, circular hole in the middle of described damped ring is arranged to flat round hole, damped ring flat round hole and lift spindle screw rod is made to increase thick Region Matching.
Wherein lift spindle screw rod carbon steel is made, and damped ring polyformaldehyde is made.
Above-mentioned improvement controls the operation principle of the lift spindle structure of lift spindle unwinding tension: when lift spindle has hung flyer bobbin back yarn, be slidably matched because flat round hole lift spindle screw rod processed in the middle of two symmetrical planes and damped ring is formed, thus to there will not be in operation process damped ring inevitably to overcome spring force because frictional force is excessive sometimes to follow lift spindle to overlap the situation of rotating together, reach the object of control lift spindle unwinding tension.
The beneficial effect improving the lift spindle structure controlling lift spindle unwinding tension described in the utility model is: the unwinding tension situation that can be applicable to all spinning, as cotton spinning, bast fibre spinning, silk spinning, chemical fibre spin, the situation such as wool spinning has continuous change along with rove weight during spinning, unwinding tension can be controlled to greatest extent, prevent the problem occurring breaking end and dropping in unwind process; Utilizing edge to join principle dexterously makes lift spindle screw rod realize relative fixing with damped ring, avoid original damped ring to overcome spring force because frictional force is excessive and follow lift spindle to overlap the phenomenon of rotating together, possess structure and simply, only on the basis of original technology, make local improvement, cost increases seldom, is convenient to the advantage promoted.
