Description
Technical field
The utility model is related to textile technology, is specifically related to a kind of front roller of the equipment for coated yarn spinning
Fast output mechanism.
Background technology
Covering yarn refers to a kind of composite yarn combined by heart yarn and sheath yarn, its feature be by outer wrapping fiber (sheath yarn) with
Heart yarn is combined, and can give full play to respective advantage, makes up the deficiency of both sides, is maximized favourable factors and minimized unfavourable ones, and optimizes the structure and characteristic of resultant yarn.
The covering yarn for being spinned on ring throstle at present is mainly long filament/chopped fiber covering yarn, and heart yarn is generally long filament, the short fibre of outsourcing
Dimension；Also there is opposite design, but purposes is less.Chopped fiber/chopped fiber covering yarn, this bag are occurred in that after the nineties in 20th century
Heart yarn refers to the covering yarn of outsourcing another kind chopped fiber spinning with chopped fiber yarn as yarn core.
1992, the Sawhney in United States Department of Agriculture south research center et al. have studied a kind of polyester staple fiber for heart yarn,
The production technology and device of outsourcing cotton short fiber covering yarn, this device are traditional ring throstles by converting.Spinning
During yarn, the cotton and polyster fibre rove prepared with conventional method are drafted respectively, thick after drawing-off subsequently into isolation channel
The control device that yarn enters before three counter extensioin rollers, has a groove to import polyster fibre thereon, and an open arc is imported
Cotton fiber, heart yarn in groove, cotton fiber onboard, according to twisting direction, cotton yarn one below heart yarn, another stock is in heart yarn
Above.What yarn splited rotarily drives cotton yarn winding heart yarn formation covering yarn.The method equipment mechanism is complicated, and repacking is inconvenient, and palpus
Bar working line is complicated, and operation inconvenience is (referring to A.P.S.Sawhney, C.L.Folk.Improved Method of
Producing Cotton-covered Polyester Staple-core yam on a Ring Spinning Frame
[J] .Textile Research, 1992,62 (1)：21-25.).
Patent CN1718887 discloses the spinning cored of a kind of " production method of short staple enveloped composite yarn and its device "
The method of yarn, specific embodiment is to have added a transfer rubber roll in the front of three roller drafting mechanisms, before rubber roll is shifted
Fang Jiayi two chopped fiber rove being spun into fluted looping roller, feeding different material, are entered with constant spacing and led
Area is stretched, after draw zone drawing-off, one is delivered directly to looping roller, into the groove of looping roller, another is first transferred to
On transfer rubber roll, then it is transported in the groove of looping roller, two coring bars twisted in groove is covering yarn.Pass through in the method
The yarn movement line for shifting rubber roll is more complicated, influences the stability of yarn.
Separately having a kind of method of open report coated yarn spinning is：Two chopped fiber yarns are spaced apart by preceding sieve
Output is drawn, wherein a coring bar is by a guide groove, guide apparatus prevent turn from transmitting and turn to the yarn, so that the palpus
The fiber of bar is wrapped on another coring bar.The channel configuration size and installation site of the method all influence covered effect (ginseng
See to appoint and learn a kind of new technology [J] textile machines that duty RING SPINNINGs produce covering yarn, 2002 (1)：15.16.)
In addition chopped fiber/chopped fiber covering yarn can successfully spin on Novel spinning machine, such as in Air-Jet Spinning, if by two
The rear roller that different staple fibres feed drafting system is planted, then can produce chopped fiber covering yarn.But due to Novel spinning machine
Cost is high, strict to fore-spinning requirement, and in China, large-scale popularization has certain difficulty.

Specific embodiment
As illustrated, being further described to the utility model：
Embodiment 1
The utility model provides a kind of front roller variable speed output mechanism of equipment for coated yarn spinning, including roller
Drafter, central shaft 1, install rotating shaft 2, driving wheel 6, driven pulley 7, the gear 8 of belt 9 additional；Roller drafting mechanism include front roller,
Middle roller, rear roller, countersunk bolts 4, upper glue roller.Front roller is constituted by fixing roller 3 and the two parts of kink roller 3 ', corresponding
Upper glue roller is made up of upper glue roller A5, upper glue roller B5 ' two parts.
Fixed roller 3 is fixedly connected with central shaft 1 by countersunk bolts 4；The kink of kink roller 3 ' on central shaft 1, by
The rotating shaft 2 installed additional is driven, and axle 2 is driven kink roller 3 ' of the kink on axle 1 by gear 8, or by driving wheel 6, driven pulley 7,
Conveyer belt 9 is driven.
Embodiment 2
The method of coated yarn spinning described in the utility model be with equipment described in the utility model as foundation (referring to
Figure).The method can spinning filament/chopped fiber covering yarn, and can spinning short fiber/chopped fiber covering yarn, it is suitable with good raw material
Ying Xing.Chopped fiber described in the utility model can be natural fiber, or chemical fibre, and its fibre length can be
Short-staple, medium-length fibre, wool type fiber.Described long filament includes ordinary chemical fiber long filament, high-performance fiber long filament, short fibre
Dimension twisted yarn.
In spinning filament yarn/chopped fiber covering yarn, its process route is (referring to Fig. 2)：Sandwich layer long filament is through front roller nip
Feeding, feeding kink roller 3 ' and upper glue roller B5 ', and another surrounding layer chopped fiber yarn feeds through rear roller jaw, after
The jaw that fixed roller 3 and upper glue roller A5 compositions are sent into after area's roller draft grips output, and two coring bars converge outside preceding jaw,
Twisted spinning is the covering yarn of chopped fiber covered filament.Its technological principle is：Long filament is by described kink roller 3 ' and gluing
The jaw of roller B5 ' compositions is gripped and exported with its superficial velocity, and chopped fiber yarn is by described fixed roller 3 and upper glue roller A5
Constitute the gripping of jaw and exported with its superficial velocity, make to fix the speed of roller 3 more than kink roller 3 ', be i.e. chopped fiber yarn is defeated
Go out speed more than long filament, when chopped fiber yarn is with long filament twisted in the shape of a spiral, be wrapped on heart yarn long filament, it is outer as covering yarn
Layer.This method is in spinning filament yarn/chopped fiber covering yarn, it is not necessary to carry out special control to the tension force of long filament, therefore can be with
Eliminate because tension force is improper or the unstable cladding for causing of tension force is bad.
When chopped fiber/chopped fiber covering yarn is spinned, its process route is (see Fig. 3)：Feed three roller drafting mechanisms
Two chopped fiber yarns, a sandwich layer chopped fiber yarn sends into front roller 3 and upper glue roller after the roller drafting mechanism drawing-off of back zone
The jaw of 5 compositions grips output, and another surrounding layer chopped fiber yarn is same after the drawing-off of back area draft mechanism, sends into kink
The jaw of roller 3 ' and upper glue roller 5B ' compositions grips output, and two coring bars converge outside preceding jaw, and twisted spinning is chopped fiber bag
Cover the covering yarn of chopped fiber.Its technological principle is：Due to the output speed of two described coring bars；Make surrounding layer chopped fiber
Yarn output speed, and is wrapped over core during with sandwich layer yarn twisted in the shape of a spiral more than the output speed of sandwich layer chopped fiber yarn
On yarn, the outer layer as covering yarn.
The above is only preferred embodiment of the present utility model, it is noted that general for the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvement can also be made, these improvement
Should be regarded as protection domain of the present utility model.
