Description
Technical Field
The utility model relates to a spinning machine spare part, in particular to spinning frame hypervelocity twisting take-up device.
Background
The spinning frame is a main machine for spinning, and is a spinning device for drafting, twisting and winding a semi-finished roving into a spun yarn bobbin in the spinning process.
The ring of the existing ring spinning frame and twisting frame is the key part of the spinning frame, which is matched with the parts of the compound moving traveller, spindle, bobbin, forming mechanism, etc. to complete the twisting and winding of the yarn. The existing ring is arranged on a ring plate and is in a ring shape, the upper part of the ring is provided with a ring-shaped track, a compound movement steel wire ring is sleeved on the ring-shaped track of the ring, and the compound movement steel wire ring can slide around the ring-shaped track of the ring at high speed. During operation, the yarn is output from the front roller, passes through the yarn guide hook and the composite moving steel wire ring on the ring, is twisted and wound on the bobbin: the composite moving steel wire ring is dragged by the yarn to slide on the steel collar, the bobbin sleeved on the spindle rotates together with the spindle, the yarn passing through the composite moving steel wire ring actively drives the composite moving steel wire ring to rotate around the annular track of the steel collar, and the twisting and winding forming of the yarn in the winding process are realized by utilizing the difference between the moving speed and the winding speed of the composite moving steel wire ring and the action of the forming mechanism along with the up-and-down lifting of the steel collar plate.
The traditional spinning twisting winding device adopts a single-motion control mode, when a spindle rotates, a ring is fixed, a compound motion traveler is completely dragged by yarn to slide on a track of the ring at a high speed, the moving speed of the compound motion traveler is passive, and the resistance change existing when the compound motion traveler slides can only slide by the rotating linear speed of a bobbin driven by the spindle, and the compound motion traveler is restricted by two conditions with the prior art level when sliding on the ring: firstly, the spindle speed is that although the spindle belt is mainly changed into the spindle belt driving to be the micro motor single driving, the lower spindle rod and the spindle foot part are still basically the same as the original spindle structure which is driven by the spindle belt, and the general spindle speed is only 20000 rpm to 25000 rpm; secondly, the sliding speed of the compound moving traveller on the ring can only reach about 42 m/s at the highest speed. The spinning frame can achieve higher yield, and the key is the speed of a spindle and the relative speed of the composite moving traveller relative to the surface of a ring when the yield is high, so the technical problems of three twisting and winding cores of the spindle, the ring and the composite moving traveller must be solved.
At present, there are also more advanced spinning twisting winding devices, which adopt a ring structure of magnetic suspension technology, such as the magnetic ring disclosed in patent application No. 200810196925.2, or a magnetic suspension ring disclosed in 200910063857, and the principle is that a permanent magnet or an electromagnetic suspension structure is adopted to separate the ring rail of the ring from the ring seat, when the compound moving bead ring slides on the ring rail, the ring is driven to move by the reaction force of the compound moving bead ring, so that the relative speed of the compound moving bead ring on the ring is reduced, and further the abrasion is reduced, thereby providing a foundation for improving the absolute speed of the compound moving bead ring.
The compound moving steel wire ring slides on the ring-shaped track of the ring, and the ring-shaped track of the ring can be driven to rotate around the axis in the same direction under the friction action, so that the relative speed of the compound moving steel wire ring on the ring is reduced. The magnetic suspension steel collar has the following defects that: the structure can not control the rotation speed of the floating ring on the circular orbit, still belongs to passive driving, and needs the yarn to drive the compound movement steel wire ring, and then the steel wire ring is driven by friction force; the speed of the suspended ring of hundreds or even thousands of spindles of one spinning frame is not consistent relative to the ring seat, and the speed of the compound motion traveller is not consistent relative to the suspended ring seat due to various reasons, so that the spinning air rings of all the spindles of the whole spinning frame are different in shape and unstable in spinning tension, and even the phenomenon that the compound motion traveller contracts to synchronously rotate the ring is possibly generated, and the broken ends of the spun yarn are increased; when the ultrahigh spindle speed is required, particularly when high count yarn is spun, the yarn strength is insufficient, so that a large amount of broken ends of the spun yarn are caused, and the spinning cannot be carried out.
