On one hand, a leather ring is adopted in a position of a middle leather roller so as to achieve fiber control of a whole drafting process, and meanwhile, the leather ring is matched with lower pins of a front zone and a back zone to respectively form a front jaw structure and back jaw structure, and therefore strength and stability of a friction zone of jaws can be enhanced, and drafting performance of the system can be effectively improved; and on the other hand, a narrow-groove type negative pressure roller matching with a negative pressure air suction system is adopted in a front drafting roller so as to achieve effective gathering before fiber twisting, and therefore resultant yarn quality can be improved effectively.
Description
Technical field
The utility model relates to a kind of omnidistance airflow concentration control drafting system.
Background technology
The RING SPINNING technology is the most a kind of spinning technique of present domestic and international application, but this technology has increased the generation of filoplume owing to the existence of twist triangle zone.Therefore, improvement for ring spinning technology especially its twisting process is the problem of spinning research and comparison hot topic always, and obtaining a series of plentiful and substantial achievements in research aspect engineering practice and the theoretical research, spin, misplace and spin etc. such as compact spinning, cable type, reduce the trigonum and then improve yarn quality to reach.A well-known brass tacks is: air-flow is a topmost measure in the RING SPINNING technological improvement, adopt the air-flow technology RING SPINNING technology especially twisting process to be improved the development that always is accompanied by spinning technique, wherein utilize negative-pressure air-flow to realize effectively gathering before the fiber twisting and then reduce the trigonum and improve the suction type of yarn quality to gather compact spinning technology be the most outstanding representative, this device laterally condenses the fibre bundle by the control zone, the width of fibre bundle is dwindled greatly, almost near the width of twist triangle zone, fibre bundle is through closely and then by twisting winding, almost every of fibre bundle fiber can both be closely in the yarn body, thereby form high performance Compact-spun Yarn:, improve the utilization rate of raw material.
Drafting system is the important component part of fine spining machine work, and its performance directly has influence on yarn quality.Improvement to the conventional spinning frame drafter also is one of the most popular research direction in the field of spinning at present, and how the Effective Raise back zone drafting multiple then to improve the total draft multiple be studying a question of comparatively paying close attention at present, and obtained a series of achievement in research.The low main cause of back area draft ability has two aspects.The one, for ease of practical operation, the back zone general structure is comparatively simple, a little less than the control to fiber, the 2nd, the rove of feeding itself is with certain twist, if thereby it is directly carried out larger drawing-off, it is irregular to produce easily drawing-off, has a strong impact on yarn quality.Therefore, for Effective Raise back area draft ability under the prerequisite that guarantees yarn quality, to increase the back zone to the control of fiber on the one hand, should make on the other hand speed change point remain on the middle part, back zone as far as possible, keep drawing-off even.And the measure that improves at present the back area draft ability is mainly to improve first aspect as main, also namely takes certain measure to increase the back zone to the control ability of fiber, and to second aspect consider less.Therefore, need counter extensioin device back zone to transform: to increase force application apparatus, with the Effective Raise back zone drafting multiple, and then improve drafting system total draft multiple, improve simultaneously yarn quality.
Summary of the invention
The purpose of this utility model provides a kind of omnidistance airflow concentration control drafting system.
The technical scheme that the utility model is taked is:
A kind of omnidistance airflow concentration control drafting system, adopt three roller counter extensioin mechanisms, comprise the front draft roller pair with bottom roll and front leather roller before the narrow slot type negative pressure, resistance twist roller, middle drawing rollers pair with the medium rubber roller of rubber ring structure and middle roller, upper pin in the rubber ring structure contains two ports, two ports are hollow, base plane contains air outlet, front port is connected hollow with rear port interface channel connects, and the negative-pressure air-suction air channel is arranged on the rear port, rear port is positioned at the first break draft district, and front port is positioned at the front draft zone.Upper leather ring is the punching rubber ring structure.
Further, front port is arcuate structure, and radian is between 90 ° to 100 °, and rear port is that incline is the rectangular structure of circular arc.
The shape in the air outlet of upper pin two-port bottom and the hole of upper leather ring can be circle, ellipse or square.
Interface channel is the semicircular arc structure, and the rubber roll shaft of medium rubber roller is embedded into this arc the inside, and two upper leather rings are tightly placed in respectively on the two ends of front and back end ports of roller and upper pin and tensioning simultaneously, and rotates to drive self rotation by roller.
In said structure, the negative-pressure air-flow that the negative-pressure air-suction air channel produces is directly delivered to the rear port of hollow, interface channel by hollow is delivered to front port simultaneously, then acts on fiber strip by the air outlet of two port bottom and the hole on the apron respectively.
Further, after adopting said structure, realizing the fiber in the drafting process for the rubber ring structure that cooperates the middle roller place controls, the apron rear end increases by a bottom pin device under middle roller, cooperate formation back zone jaw structure with the apron that is stretched in upper pin rear end, realization is to effective gripping of fiber, then realize the fiber aggregate control of back area draft process by the negative pressure of upper pin rear port, strengthen the back zone to effective control of rove yarn, simultaneously, the rove yarn is under the effect of this power, and control speed change point is moved to the right front neighbouring by original drawing rollers, realization is to the uniformly and effectively high draft of rove with certain twist, Effective Raise back area draft ability.
Equally, the apron front end increases by a bottom pin device under middle roller, cooperate the formation jaw structure with the punching apron that is stretched in upper pin front end, realization is to effective gripping of fiber, then realize the fiber aggregate control of proparea drafting process by the negative pressure of upper pin front port, strengthen the proparea to effective control of fiber strip, can strengthen on the one hand the effective control to the district's fiber that swims, can so that concentrate speed change point position, realize even drawing-off on the other hand.
Owing to adopt major diameter narrow slot type hollow roller to replace original front bottom roll, thereby increased length of floating area in the front draft zone, so that the proparea is to the control decline of fiber.Therefore, at the anterior pressure bar that adds of upper pin front port, dwindle length of floating area, realize the effective control to the district's fiber that swims.
In specific implementation process, because the rove that feeds is different, mainly be that the initial twist of rove is different, therefore, can regulate the vacuum magnitude that the air draught air channel provides, the Optimization Technology configuration improves the drawing-off effect.
Omnidistance airflow concentration control drafting system of the present utility model, adopt on the one hand apron to realize fiber control in the whole drafting process at the medium rubber roller place, jaw structure before and after the downside pin in district forms respectively before and after cooperating simultaneously, strengthen intensity and the stability thereof of jaw place friction field, Effective Raise system drawing-off ability; The front draft roller is to adopting narrow slot type negative pressure roller to cooperate the negative-pressure air-suction system to realize effectively gathering the Effective Raise yarn quality before the fiber twisting on the other hand.
