Abstract
The invention provides a technical scheme of a three-roller high-speed spinning drafting device suitable for a spinning unit of a spinning and knitting combination machine. The drafting device is characterized in that an upper roller and a lower roller of a non-cantilever type simply supported beam are adopted for supporting, an independent three-roller cylinder is adopted for pressurizing, so that not only can stable pressurization be beneficial to holding and eliminating of spindle difference and high-speed spinning, but also three pairs of roller pressurization values and pressurization value allocation technological parameters are conveniently adjusted, and pressurization and pressure relief for a single device or the whole device can be carried out.
Description
Technical field
The present invention relates to a kind of textile equipment, especially for three roller high-speed spinning drafting systems of knitting machine.
Background technology
Spin the spinning, drawing part of knitting combination machine, owing to arranging dozens of around the periphery of knitting machine, there is the spinning unit of drawing-off, twisting and/or false twisting part, in order to improve the prouctiveness of the knitting combination machine that spins as much as possible, it is necessary to arrange more spinning unit. Thus the spatial arrangements in knitting machine circumference of each spinning unit is compact. Simultaneously in order to work asynchronously with knitting machine, each spinning unit must individually drive again control. Therefore, each spinning unit is necessary for including the structures such as about at least three pairs roller draft jaws and pressure-producing part, drive motor and control part, twisting and/or false twisting mechanism, rove feeding and detection thereof, and the Synchronization Control of spinning unit and knitting unit. Owing to structure member is many, spaces compact, drawing-off pressing mechanism of the prior art adopts the drawing-off pressure structure simplified, as German application people's number of patent application is: the application for a patent for invention of 201480016644.8, the pressurization proposing spinning unit adopts simple torsion spring to be the technical scheme of pressurized source, and pressure transmission is the top drafting rollers pressuring method of cantilever beam structure. Because sliver output lead speed several times to more than the ten times ground of drawing-off part is higher than common RING SPINNING, very easily making drawing-off grip the stability controlled and reduce, thus affecting spinning quality, being even prone to occur broken end to affect production efficiency.
Summary of the invention
It is an object of the invention to provide the technical scheme of three roller high-speed spinning drafting systems of a kind of knitting combination machine spinning unit that is suitable to spin, its top roller adopting non-cantilevered simply supported beam and bottom roll supporting, and three independent roller cylinder pressurizations, it is poor that useful gripping of not only stably pressurizeing eliminates ingot, be conducive to high-speed spinning, and it is easy to three pairs of roller loading values and the technical arrangement plan of pressurization value distribution thereof, it is also possible to implement single device or complete machine pressurization and release of pressure.
The implementation of the present invention is:
A kind of drafting system of knitting machine, including upper bottom roll after in before wallboard, feeding double horn mouth, drawing-off grip portions to, in up and down apron to rear lower apron, the reel cage of pressures partially and roller drive control part, it is characterized in that the double; two ingot sliver of each upper and lower roller nip spinning, the pressurization of each top roller axle is adopted rolling bearing supporting and Indivudual cylinder pressurization in the middle part of simply supported beam by pressurized cradle, and the pressure of three top rollers needs to be independently arranged according to technique.
Three bottom rolls of drafting system adopt the rolling bearing supporting of simply supported beam two ends, and front roller head end adopts independent support, and middle rear roller head end adopts and the support of downside pin one.
Adopt non-cantilevered top roller or top roller and bottom roll, top roller application individual cylinder pressurization simultaneously, the double; two ingot sliver pressure grippings in upper and lower roller nip can be made stable, avoid the drawback that cantilever pressure structure roller nip stress is axially inconsistent, reduce the adverse effect of double; two ingot sliver pressure differential counter extensioin quality, it is poor that useful gripping of not only stably pressurizeing eliminates ingot, be conducive to high-speed spinning, and the pressurization of the cylinder of three pairs of roller Independent adjustable and pressurization distribution thereof, it is ensured that the long-term stability of the reasonable and Drafting quality of pressing technology.
Accompanying drawing explanation
Fig. 1 is the front elevational schematic of spinning, drawing unit of the present invention.
Fig. 2 is the schematic side view of spinning, drawing unit of the present invention.
Fig. 3 is the front elevational schematic that spinning, drawing unit of the present invention increases bottom roll simply supported beam support.
Detailed description of the invention
In Fig. 1 Fig. 2, a kind of drafting system of knitting machine, wallboard 11 be provided with double horn mouth 10, rear upper bottom roll 8 and 9, in upper bottom roll 6 and 7, front upper and lower roller 4 and 5, pressurized cradle 3, in after bottom roll drive motor 2, front lower roller drive motors 1, top roller pressurized cylinder after in before being provided with in pressurized cradle 3. Before in after top roller axle be in the middle part of simply supported beam rolling bearing supporting.
The source of the gas of cylinder pressurization can 1-3 road supply, therefore three row top rollers after in before the drafting system on complete machine spinning unit can be supplied respectively and arrange pressurization value.
The drafting system of each spinning unit is provided with electromagnetic gas valve, individually controls the supply break-make of this unit reel cage upper cylinder, it is simple to the running operation of production process.
The transmission of drive motor 1 and the 2 pairs of front bottom rolls 5, middle bottom roller 7 and rear bottom roll 9, the opposite side at wallboard 10 adopts Timing Belt 12 and synchronous belt pulley transmission, or adopts gear drive.
In figure 3, in before drafting system, rear three bottom rolls adopt the rolling bearing supporting of simply supported beam two ends, and front bottom roll head end adopts independent support 13, in, rear bottom roll head end adopt with in, two supports 14 and 15 of rear downside pin one.
