Description
Technical field
The invention belongs to the technical field of spinning, drawing machinery, more particularly to a kind of spinning, drawing with effect of gathering
Device.
Background technology
As the continuous progressive and innovation of China's spinning technique, the competition in yarn market are further fierce, people are to yarn matter
The requirement of amount also more and more higher, mainly dry to yarn strength, cotton knot, filoplume, the bar, aspect of yarn defect five has higher requirements.More than
Five aspects are mainly and are determined by spun yarn drafting system, it can be seen that spun yarn drafting mechanism is the core of yarn drafts.Leading
During stretching, fiber strip is mainly acted on by following five kinds of power:The gripping of interfibrous cohesive force, roller nip to yarn
Power, faster fibres are to drafting force, the faster fibres of slow speed fiber to the directed force and slow speed fiber of floating fiber to the fibre that swims
The controling power of dimension.Because the effect of five kinds of power by more than causes that fiber movement is unstable, therefore to obtain yarn quality higher
Yarn, the reasonability and stability that five kinds of power of the above are controlled fiber movement are crucial.
Traditional RING SPINNING drafter is made up of roller and apron, wherein, most widely used is double short skins
Circle and length tape drawing mechanism.The friction field formed by elastic nip in both drafters is controlled in drawing-off
Fiber strip, in whole main drawing area, it plays vital effect.In double-short leather-ring drafter, elastic nip
Near front roller nip, the length in area of swimming is shorter, but with the increase of spinning speed, the friction between double-short leather-ring is increasingly
Greatly, apron service life is short, easily fiber strip is produced and is rubbed, so that yarn quality is influenceed, therefore, it is difficult to improve double-short leather-ring
The production efficiency of drafter.Compared with double-short leather-ring drafter, apron long service life long in length tape drawing mechanism,
But its length of floating area is long, control of the elastic nip to floating fiber is poor, and this expands floating fiber floating fibers scope,
Fiber Velocity unstability increases in drafting process.Also, the shortening in length tape drawing mechanism to length of floating area is difficult to
Realize.
At present, to reduce spun yarn main drawing area length of floating area, many new weighing drafts are have developed both at home and abroad, mainly
It is to be improved to selling up and down, such as improvement in length apron draft form to lower pin --- Switzerland is vertical to reach R2P, SKF drawing-off shape
Formula, the application sold under Ma Zuoli circular arcs;To the improvement of lower pin in double-short leather-ring weighing draft --- domestic JF, HP double short apron
Weighing draft;Weighing draft --- RS-6833C types, RS-6833D types, RS-6833DQ types, the RS- of stamp before also upper pin
Application sold in 6939S type spun yarn straight panels etc..Above-mentioned new weighing draft improves main drawing area and adds to a certain extent
The distribution of friction field, effectively shortens length of floating area, and yarn quality also improves a lot.But it is main after the preshoot of upper pin
Draw zone mid-rubber roll reduces with the contact surface of middle roller, causes upper and lower apron to move unstable, and ingot difference is larger;After lower pin sinks,
Weaken curable grip and controling power of the cushion rubber middle part to fiber.In addition, because lower apron is to drive it to rotate by middle roller,
And upper leather ring is rotated by the friction drive effect of lower apron, therefore up and down there is intrinsic difference in the speed of apron, with
The increase of spinning frame use time and the lifting of speed, the friction of upper and lower apron easily cause the friction to fiber, and are also easy to produce
Electrostatic, cause flyings, increase harmful filoplume, causing being greatly reduced for yarn quality.Additionally, irregular, the table of apron internal structure
The bright and clean degree in face can also influence on the rotation of upper and lower apron, so as to influence yarn quality.
It is being that while being improved, the country also occurs in that and removes traditionally lower pin, upper hypodermis to traditional apron draft shape
The new weighing draft of circle, patent of invention " a kind of pair of soft drafting system of S curve " (patent of Deng Wansheng, Wan Lianyi, Dong Jingsong
Number:201410528595.8) the flexible gripping by being formed using S curve plate, curve pipe, grid ring acts on control fiber strip
Drawing-off, be obviously improved resultant yarn strand.Because it uses grid ring to substitute apron, the abrasion that grid ring is subject to is larger, makes
Low with the life-span, additionally, control of the grid ring to fiber strip is weak compared with apron, the distribution of Fiber Velocity point can not be led fully to reach
Easily skidded during stretching, improve resultant yarn strand not notable, it is difficult to realize commercial application.Journey steps on the utility model patent of wood
" compact spinning " (patent No.:200620112382.8) purpose is intended to by installing negative tube, net additional between front roller and middle roller
Lattice circle, negative tube has the air-breathing groove for becoming narrow gradually, after fiber strip is through drawing-off, the jaw before grid ring is transported in yarning part
While attracted by air-breathing groove and be gradually collected in grid ring surface-slit, so as to reduce resultant yarn filoplume, improve yarn quality,
But because the device must undertake drawing-off task while gathering, therefore it is difficult to acquisition and effectively gathers, and the abrasion of grid ring is huge
Greatly, it is difficult to bear commercial application.
The control of floating fiber is all insufficient during these above-mentioned method counter extensioins, can only partly improve resultant yarn matter
Amount, because the wearability of grid ring is difficult to be met, causes yarn quality unstable, and production cost is higher, is unfavorable for industry
Change application.
