Abstract

The invention discloses a low negative pressure gathering device for high draft of annular spindle spun yarn. The low negative pressure gathering device for high draft of annular spindle spun yarn is a draft device of an annular spindle spinner and comprises a front roller, a front leather roller, an upper leather ring, a lower leather ring, an upper leather ring pin and a lower leather ring pin, wherein the upper leather ring pin and the lower leather ring pin are used for fixing the upper leather ring and the lower leather ring respectively and fixed to a rack, the lower leather ring pin is replaced by a hollow lower air draft pin, the shape of the upper surface of the lower air draft pin is the same as that of the upper surface of the lower leather ring pin, only a narrow groove hole is formed in the upper surface, close to the front leather ring, of the lower air draft pin, an air draft device is arranged on the bottom face of the lower air draft pin, and the lower air draft pin extends forwards 3.5 mm to 5 mm relative to the upper leather ring pin; a single row of small holes are formed in the central line of the lower leather ring at intervals so that the lower leather ring with holes can be formed or a lattice ring is adopted. The low negative pressure gathering device for high draft of annular spindle spun yarn overcomes the defect that an existing device is much in hairiness of resultant yarn and has the advantages of being small in investment and low in consumption and pollution. Under the action of negative pressure airflow, spread fibers are aggregated to fiber strands, long harmful hairiness is reduced, short useful hairiness is reserved, and the width of the fiber strands can be changed through compression so that the width of a twisted triangular area can be kept.

Description

A kind of lower negative pressure aggregate device for ring spindle yarn high draft
Technical field
The present invention relates to textile machine, specifically refer to a kind of lower negative pressure aggregate device for ring spindle yarn high draft.
Background technology
Some is the research of the spinning technique of the rove amount of resetting, spun yarn high draft about " high efficient technology " in recent years, because this new technology has immeasurable value to the saving of the energy, manpower and physical resources, obtain showing great attention to of enterprise in all parts of the country, Some Enterprises is just being tried to explore application.
The defects such as running into some and be difficult to overcome one's shortcomings in ring spindle yarn high draft new technology application process, is mainly that resultant yarn filoplume is many, corresponding yarn strength deficiency.Due to the existence of this defect, also just hindered further developing of this new technology.
Meanwhile, the resultant yarn filoplume problem in traditional RING SPINNING technology is also that people make every effort to the important subject solving for a long time.Since over half a century, many Novel spinning machines and spinning new technology have been there is, although can solve resultant yarn filoplume problem, but produce again many negative drawbacks simultaneously, as the change of yarn formation structure, make the wearability variation of conventional fabrics, and scrap build investment cost is large, power consumption is large, and production cost improves.
If Fig. 1 is former ring spinner section drafting system schematic diagram, comprise front roller 9 ', front leather roller 10 ' and upper and lower apron 8 ', 2 ', Xiao 1 ' under Xiao 12 ' and apron on fixing upper and lower apron 8 ', 2 ' apron, on apron, Xiao 12 ' and lower Xiao's 1 ' vertical alignment are fixed in frame, and front leather roller 9 ' and upper and lower Xiao 12 ', 1 ' horizontal range are 12mm.
It is when rove bar is during by front roller nip drawing-off that resultant yarn filoplume produces reason, fiber number in draw zone reduces gradually, the dynamics that connects each other between each fiber weakens, outside out of hand being diffused in of part limit fiber, or the head layer end of limit fiber stick up more longer, simultaneously because the relative friction between fiber in drafting process produces electrostatic phenomenon, between fiber, produce mutual repulsive force, spinning-drafting multiple is larger, produces electrostatic repulsion forces also larger, and the diffusion phenomena of limit fiber are even more serious.In addition, regular roving feeding increases, and the yarn width of draw zone is increased, when spinning the spun yarn of identical yarn count, between its fiber to connect dynamics each other more weak, finally cause the resultant yarn filoplume after spun yarn high draft more, the corresponding reduction of yarn strength.
Summary of the invention
The object of the present invention is to provide a kind of lower negative pressure aggregate device for ring spindle yarn high draft, to overcome the defect that resultant yarn filoplume is many, and small investment, low consumption.
The object of the invention is achieved through the following technical solutions: a kind of lower negative pressure aggregate device for ring spindle yarn high draft, for ring spinner drafting system, comprise front roller, front leather roller and upper, lower apron, on fixing, Xiao under Xiao and apron on the apron of lower apron, on apron, under Xiao and apron, Xiao is fixed in frame, with Xiao under hollow air draught, substitute Xiao under apron, under air draught, Xiao's upper surface shape should be identical with the upper surface shape of Xiao under apron, just at the upper surface near front apron, have narrow slotted eye, under air draught, Xiao bottom surface is provided with air intake device, Xiao Qianshen 3.5~5mm on the relative apron of Xiao under described air draught, by establishing single-row interval aperture on lower apron center line, become lower apron with holes or adopt grid ring.The present invention has overcome the many defects of resultant yarn filoplume for the lower negative pressure aggregate device of ring spindle yarn high draft, has scalp, low consumption, low pollution.
On such scheme basis, the order number of described grid ring (5) is 1000 orders/cm 2, be low mesh number grid ring.
On such scheme basis, described air intake device is connected and composed through flexible pipe and broken end air-suction trunk by air draught junction block, and described broken end induced-draught fan power is 3 kilowatts.2.2 kilowatts of former broken end induced-draught fan power are increased to 3 kilowatts to guarantee air draught effect.
The invention provides a kind of purposes of the lower negative pressure aggregate device for ring spindle yarn high draft, can be used for spinning siro-spinning yarn or etc. line density segment-colored mixed color yarn.
Superiority of the present invention is: overcome the many defects of existing equipment resultant yarn filoplume, had scalp, low consumption, low pollution, be in particular in:
(1) in draw zone inner edge drawing-off limit polymerization, utilize the active force of negative-pressure air-flow that diffusion fiber is aggregated on yarn, reduce harmful plumage that becomes mildewed, remain with and use undercoat plumage, the width of compressible change yarn, to keep the width of twist triangle zone, the good yarn formation structure that has kept tradition to spin;
(2) keep original pair of cushion rubber elastic nip drawing-off mode, also keep original draft process characteristic, avoid new problem to produce;
(3) utilize the feature of crawl space that upper and lower apron, front roller, front leather roller etc. form, make negative pressure tolerance utilization rate high, waste littlely, air consumption is little, so the present invention can adopt lower negative-pressure air-suction machine, and power consumption is also lower;
(4) cleaner production environment, is sucked the dust flyings that produce in spinning-drafting process in time, reduces the pollution in workshop, can reduce the rate of ventilation in workshop simultaneously.
