Abstract
The invention provides a method and a device for carrying out false twisting spinning by the linear and rotation composite motion of a tangential belt. The device comprises the round tangential belt and a transmission mechanism of the round tangential belt. The method and the device are characterized in that when the tangential belt takes the axial linear motion by the tangential belt transmission mechanism, the tangential belt also takes the rotating motion by taking the axis of the tangential belt as the center, i.e. the tangential belt takes the linear and rotation composition motion to carry out false twisting on slivers and conveying the slivers. The slivers are driven by the linear motion of the tangential belt to roll around the center of sliver bodies to generate the false twisting degree and by the rotation motion of the tangential belt, the slivers which are contacted with the tangential belt and axially move are conveyed to the downstream due to the spinning of the tangential belt, so that the quality influence caused by the sliding friction between the slivers which axially move and the tangential belt is eliminated or reduced.
Description
Technical field
The present invention relates to the spinning equipment field, particularly the method and apparatus of additional false twisting in the ring throstle spinning process.
Background technology
In the ring throstle spinning process; Improved the history of spinning process condition and/or the existing many decades of yarn property through the method for additional false twisting on the spinning bar; False-twisting device all is arranged on front roller nip in the spinning section between the twizzle in disclosed technology; Mechanical false twisting type roughly is divided into technical schemes such as mechanical type center friction-driven, sheave surface friction rolling, double-wheel-disc or the afterturn of wheel disc group, two-sided belt or the afterturn of belt group, single contact-segment tengential belt mantle friction rolling, two contact-segment tengential belt mantle friction rollings according to sliver false-twist motion mode; What have in these schemes only is suitable for laboratory applications, and complicated investment of the structure for false twisting that has and/or operating cost are higher, the scheme production operation inconvenience that has; Thereby, be not all to be suitable for commercial application.
Comparatively speaking, the structure for false twisting relativity price ratio that the single contact-segment of above-mentioned employing or two contact-segment tengential belt mantle friction are rolled is higher, is convenient to as suitability for industrialized production.Single contact-segment tengential belt mantle friction rolling structure for false twisting is open by US2590374 United States Patent (USP) in 1949; Two contact-segment tengential belt mantle friction rolling structure for false twisting were applied for into open by Australia in 1996; One Chinese patent application of the same clan number is 97192676X, and it is the potential utilization to US2590374 United States Patent (USP) structural principle.This structure is provided with the circular tengential belt of a circulation in the spinning section; Make the corresponding positive and negative that contacts spinning section sliver of positive and negative of two sections tengential belts of reverse motions; And make sliver form the angle of contact that contacts with tengential belt; During circle tengential belt rectilinear motion, sliver produces the rotation of rolling under coefficient of friction between sliver and the tengential belt and the effect of angle of contact pressure, realize the false twisting to sliver.
In the prior art, in the mechanical type false twisting mode and structure of tengential belt structure for false twisting or above-mentioned other type, sliver and false twisting element are to do the relative motion of perpendicular each other.On the one hand, sliver and false twisting interelement must be provided with a suitable coefficient of friction, could drive sliver by false twisting element CONTACT WITH FRICTION and rotate around self axle center or roll and produce the false twisting twist; On the other hand, with respect to the axially-movable of sliver, sliver and false twisting interelement produce the surperficial sliding friction with normal pressure.Be the CONTACT WITH FRICTION of sliver and false twisting element, can be decomposed into tangential, sliver surface and false twisting element surface rolling friction, and the sliver surface axially and the sliding friction of false twisting element surface.The former is the driving force that produces the false twisting twist, and the latter's sliding friction causes the adverse effect to the sliver surface quality to a great extent, like the increase of faults such as filoplume, cotton knot.
Therefore, structure for false twisting of the prior art all exists disadvantageous sliver axially-movable sliding friction between false twisting element and sliver, and this is the in addition perfect problems of needs, but does not see progress to some extent so far.
Summary of the invention
The objective of the invention is to disclose a kind of false twisting technical scheme that adopts the circular loop tengential belt as the false twisting element; It can overcome the above-mentioned deficiency of existing false twisting technology; Eliminate or alleviate disadvantageous sliver axially-movable sliding friction between sliver and the tengential belt, thereby optimize structure for false twisting, improve the false twisting quality.
Technical scheme of the present invention is:
The method of tengential belt straight line rotation compound motion false twisting spinning; Comprise circular tengential belt and transmission mechanism thereof; It is characterized in that the tengential belt transmission mechanism is that the center rotates with the tengential belt axle center also when making tengential belt make axial linear movement, promptly tengential belt carries out false twisting and carries sliver sliver with the compound motion of straight line and rotation.
The device of tengential belt straight line rotation compound motion false twisting spinning comprises circular tengential belt and transmission mechanism thereof, it is characterized in that the tengential belt drive is to make tengential belt produce straight line and the tengential belt power wheel hub that rotates compound motion.
Described tengential belt power wheel hub is provided with four pairs of tengential belt swiveling wheels at least on the circumference of wheel hub supporting tengential belt right; Swiveling wheel is to being worm gear or helical gear composition; Swiveling wheel pair worm screw or the initiatively helical gear engagement concentric with the wheel hub axle center, worm screw or active helical gear are fixed on the wheel hub main shaft, and main shaft is by drive power source; When rotating, hub body is also driven by the hub body transmission mechanism and rotates at the swiveling wheel of tengential belt power wheel hub upper support tengential belt.
Tengential belt is looped around the revolution that circulates between at least two wheel hubs, and main shaft obtains driving force around tengential belt axle center rotation to rotating, make the tengential belt that is supported in the same way at the section around wheel hub through worm screw or active helical gear drive swiveling wheel on the one hand; Hub body is driven by the hub body transmission mechanism on the other hand, and hub body is rotated, and drives tengential belt rotation around the wheel hub axle center, is in two tengential belts between the wheel hub and produces rectilinear motions.Thereby realize the straight line and rotation compound motion of tengential belt.
