Description
Technical field
The utility model relates to spinning new technical field, the two Congregate compact spinning devices of specifically a kind of drawing-off.
Background technology
Compact spinning is a kind of Advanced Spinning Technologies spinning on improved ring throstle, and it by increasing a fibre deposition district to improve yarn quality before ring throstle draw-gear.But current compact spinning system be all at proparea yarn after drawing-off, twisting before assemble, to reduce twist triangle zone, improve yarn quality, and yarn in counter extensioin district also only limits to increase friction field by the mechanism such as apron or pressure bar, then increase the control to fiber, also do not realize for the control of gathering at draw zone fiber.Meanwhile, when traditional ring spinning is carried out to the negative pressure type compact spinning system reform, need to again add and gather negative-pressure air fan, and design corresponding negative pressure air channel, increase machine material consumption.For this, the utility model provides the two Congregate compact spinning devices of a kind of drawing-off.This device front roller adopts the narrow slot type hollow roller that diameter is 50mm, middle roller adopts the narrow slot type hollow roller that diameter is 25mm, and in lower apron adopt punching apron, middle upper leather ring adopts punching apron, coordinate the upper pin assembly of hollow structure to realize the fiber aggregate in drafting process, simultaneously upper punching apron with in lower punching apron form and there is the front and back jaw structure that gathers negative pressure, effectively improve yarn quality; On the other hand cotton the collection on original ring throstle air channel is adopted to four air channel technology: one of them air channel is used for collecting cotton, negative pressure is gathered for the hollow front roller of narrow slot type provides in an air channel, negative pressure is gathered for the hollow middle roller of narrow slot type provides in an air channel, negative pressure is gathered for punching upper leather ring provides in an air channel, realize the cotton negative-pressure air fan dual-use of collection, save the negative-pressure air fan that gathers that needs interpolation in transformation, reduce machine material consumption and system capacity consumption in transformation.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of compact spinning apparatus that can gather in draw zone realization pair, to improve resultant yarn comprehensive quality.
In order to address the above problem, the technical scheme that the utility model is taked is that ring throstle adopts three roller drafting mechanisms, comprise the first break draft roller pair being formed by rear roller and rear roller, there are the middle drawing rollers pair of the medium rubber roller of punching rubber ring structure and the hollow middle roller composition of narrow slot type that diameter is 25mm, the front draft roller pair that the hollow front roller of narrow slot type negative pressure that is 50mm by diameter and front leather roller, resistance twist roller form.
In said structure, all contain air draught assembly at the hollow front roller of narrow slot type negative pressure and the hollow middle roller of narrow slot type inside, for realizing the effect of gathering of fiber in the hollow middle roller counter extensioin of narrow slot type process, in lower apron adopt punching apron, punching rubber ring structure on medium rubber roller comprises pin and apron, described apron is punching apron, described upper pin comprises front port, two ports of rear port and intermediate connecting mechanism, described two ports are hollow, base plane contains air outlet, described air outlet is circular or square, described front port is arcuate structure, radian is between 90 ° to 95 °, described rear port is arcuate structure, radian is between 85 ° to 90 °, negative pressure line is contained on described rear port top, described front port is connected by intermediate connecting mechanism with rear port, described intermediate connecting mechanism is the hollow structure of arc, in described medium rubber roller upper leather ring structure, the rear port of upper pin is positioned at first break draft district, front port is positioned at front draft zone, when use, described upper pin is embedded into by arc intermediate connecting mechanism in the rubber roll shaft of roller, the upper leather ring that simultaneously punches is tightly placed in respectively on the front and back end ports of roller and upper pin and tensioning, and rotate and drive its rotation by roller, the lower apron of punching is tightly placed in respectively front downside pin, rear downside pin, on leather ring tension frame and tensioning, and rotate and drive its rotation by roller in Pendulum Weighting Arm System situation, be stretched in the punching upper leather ring at pin front port place simultaneously and be stretched in apron composition inside under the punching on front downside pin and there is the front jaw that gathers negative pressure, be stretched in the punching upper leather ring at pin rear port place and be stretched in apron composition inside under the punching on rear downside pin and there is the rear jaw that gathers negative pressure.
In above-mentioned punching rubber ring structure, the negative-pressure air-flow that negative-pressure air-suction air channel produces is directly delivered to the rear port of hollow, be delivered to front port by the syndeton of hollow simultaneously, then act on fiber strip by the hole on air outlet and the punching upper leather ring of two port bottom respectively, realize the fiber aggregate in drafting process; The negative-pressure air-flow that negative-pressure air-suction air channel produces is directly delivered to the air draught assembly of the hollow middle roller of narrow slot type inside, then acts on fiber strip by the hole on narrow groove and the lower apron of punching of surface of roller respectively.
Due to front roller and middle roller employing narrow slot type hollow roller, medium rubber roller adopts punching rubber ring structure, therefore needs to increase and gathers accordingly negative-pressure air-suction system, thereby increase machine material consumption and the energy consumption in transformation.For addressing this problem, cotton collection on original ring throstle air channel is adopted to four air channel technology: one of them air channel is used for collecting cotton, negative pressure is gathered for the hollow front roller of narrow slot type provides in an air channel, negative pressure is gathered for the hollow middle roller of narrow slot type provides in an air channel, negative pressure is gathered for punching upper leather ring provides in an air channel, realize the cotton negative-pressure air fan dual-use of collection, save the negative-pressure air fan that gathers that needs interpolation in transformation, reduce machine material consumption and system energy consumption in transformation.
Gather negative pressure because the cotton bellows of collection will provide, therefore, need to keep the negative regulation of the cotton air draft system of collection, so that the stable negative pressure of gathering to be provided.Therefore, in collection hopper, add the automatic cotton-sweeping equipment of pressure sensitive, to remove in time the cotton-wool on bellows Inner filter net, keep the stable of the cotton air draft system negative pressure of collection.
In said structure, middle roller adopts the narrow slot type hollow roller that diameter is 25mm, and in lower apron adopt punching apron, middle upper leather ring adopts punching apron, coordinate the upper pin assembly of hollow structure to realize the fiber aggregate in drafting process, simultaneously upper punching apron with in lower punching apron form and there is the front and back jaw structure that gathers negative pressure, can realize two the gathering in drafting process, effectively improve yarn quality.
