Abstract
The present invention is the rove series suspension spindle that automatic constant draws yarn tension, relate to yarn and spin spinning frame field of components, currently used lift spindle draws yarn tension can not be constant, when the full yarn of flyer bobbin, easily produce unexpected elongation harmful drafting, when rove is close to blank pipe, sliver easily drops, cause unexpected little micro-joint drawing-off, form long snick yarn defect, include drawing yarn tension at lift spindle cap built with weight spring and damping spring adjustment for this technology disclosed by the invention, on the basis of said structure, then add a tension force again transfer the files device when wider lead-in wire tension range, a first presetting fixing control power, then remaining force value is controlled with spring again. the present invention has makes all conventional raw material series rove draw the feature that yarn tension is constant, has simple in construction simultaneously, and cost only has trickle increase, it is simple to the beneficial effect of popularization.
Description
Technical field
The present invention relates to field of textile machinery, especially cotton spinning, bast fibre spinning, silk spinning, wool spinning, the raw material series spinning frame parts that chemical fibre spins.
Background technology
Arriving spinning process again through Roving Frames in fabrication processes, in Roving Frames, spun rove is wrapped on flyer bobbin, is then installed on lift spindle by flyer bobbin, then rove is drawn to spinning frame carry out next step processing. Along with the operating of spinning frame, rove is constantly drawn past spinning frame from flyer bobbin and twists with the fingers thin. In order to the speed making traction is uniform, technology before having had been used up on lift spindle 20 years at present, the i.e. early 1980s, by longitude and latitude weaving with Shanghai two is spun and Ministry of Textile Industry equipment department combines in the trial-production of plastics textile workpiece factory of Jiangyin City, signed and formulated ministry standard in 8 or eight years by ministerial level, but this technology continues up and still using till now. This technology, primary structure is damping lid and steel ball bowl structure, is adjusted on the damping value of design by the frictional force between them, can not automatically adjust and draw yarn tension in operation process. But lift spindle frictional force is affected by gravity, when rove gravity is big, then to draw greatly yarn tension also big for frictional force; If frictional force is constant, draw yarn tension also by the impact drawing the change of the yarn arm of force, draw the yarn arm of force during the full yarn of flyer bobbin maximum, at this moment draw yarn tension and tend to reduce. Affecting bigger factor in both is gravity. When on flyer bobbin around full rove, the gravity that lift spindle bears is maximum, and frictional force is maximum, during traction coarse sand, it is easy to unexpected elongation harmful drafting occur, adds the manipulation strength of spinner, and affect spinning quality; When the rove being wrapped on flyer bobbin gradually decreases, frictional force also reduces, and under equal pull strength traction, sliver easily drops, and now flyer bobbin stops operating. Along with the carrying out drawing yarn action, cause unexpected little micro-joint drawing-off when the length rear yarn rostrum ruing out of tenesmus so rotates (now draw yarn tension maximum), form the long snick yarn defect of spun yarn.
Summary of the invention
The purpose of the present invention, for providing a kind of simple in construction, can be automatically adjusted that to draw yarn tension be steady state value, eliminates the coarse sand series suspension spindle of broken end and falling phenomenon.
The technical scheme realizing above-mentioned purpose is as follows:
The rove series suspension spindle of automatic constant damping, there is lift spindle main body and lift spindle cap, axis direction at lift spindle cap is fixed with lift spindle screw rod, 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 set, lift spindle set and lift spindle main body connect by pin is fixing, it is set with the weight spring overcoat with shoulder at lift spindle screw rod tail axis direction, weight spring it is set with between weight spring overcoat and lift spindle screw rod, shoulder at weight spring overcoat is set with ball retainer, equipped with multiple steel balls rotating contact on ball retainer, the steel ball bowl with steel ball movable contact it is set with above ball retainer, the bottom of steel ball bowl is lift spindle inner sleeve, it is set with above steel ball bowl and the damping lid of steel ball bowl sliding contact, it is set with damping spring outside damping tops and between lift spindle cap inside top, lift spindle cap it is set with above damping spring.
It is 8kg 300g that weight spring controls rove gravimetric value, and it is 1.5 8g that damping spring controls tension in the roving value.
Damping lid polyformaldehyde is made.
Above-mentioned automatic constant draws yarn tension Suspended Spindle for Roving operation principle: when being wrapped over rove (full yarn) on flyer bobbin, it is maximum that lift spindle bears strength, gravity passes through lift spindle main body, lift spindle inner sleeve, steel ball bowl, ball retainer is delivered to weight spring overcoat, weight spring overcoat is moved down by action of gravity, and then have compressed its internal weight spring, and now damping spring elongation, damping force reduces; Otherwise, when rove is close to blank pipe, the pressure of gravity spring is alleviated by rove, and gravity spring extends, damping spring pressurized, and damping force increases, and draws yarn tension and keep constant in the continuous each other growth and decline of damping force and gravity.
What the present invention can be suitably used for all spinning draws yarn tension situation, such as cotton spinning, bast fibre spinning, silk spinning, when the situations such as chemical fibre spins, wool spinning have along with spinning, rove weight is continually changing, yarn tension can be drawn by automatic constant, it is therefore prevented that broken end and the problem of tenesmus occur in drawn yarn process; Being provided simultaneously with simple in construction, only make local improvement on the basis of original technology, cost increases seldom, it is simple to the beneficial effect of popularization.
