CS231060B1 - Guide device for core yarn production - Google Patents

Abstract

The invention relates to a device for producing core yarn on a ring spinning machine and to a method of ensuring perfect spinning of synthetic silk with staple fibers. The essence of the invention lies in the fact that on the slat in the drawing field of the spinning machine there is an adjustable fixed beam, in which are inserted support arms carrying the roving yarn guide and a guide roller for guiding synthetic silk. Synthetic silk is guided in the groove of the guide roller to the output pressure roller, along the circumference of which it reaches the center of the fiber strand in the grip of the output pair of drawing rollers and forms a core yarn after leaving the rollers. The invention can be used in the textile industry.

231 060

BACKGROUND OF THE INVENTION The present invention relates to a guide device for producing core yarns and solves the problem of providing perfect filament yarn splicing with staple fibers.

The process of forming a nuclear yarn is carried out in a number of known ways in the world.

A device is known in which the wrapping of the last roll is changed by setting a double roll. The two conductors used are fixedly fixed on the pressure arm, yet a device is used in which the tensioning device is a ceramic bracket. Synthetic silk enters under the exit roller through the guide loop,

In another embodiment, the synthetic silk is guided over the guide rod by a tensioning device to the feeding eyelet, which is positioned close to the upper pressure roller. The guide eyelets are positioned at the edges of the adjustable shoulder.

So far, a device is also used in which the synthetic resin is passed through the porcelain eyelet and the guide rod under the outlet pressure roller. In this way, the tension of the synthetic silk is not solved.

The disadvantage of these devices lies in the stationary transfer of the individual guide elements for guiding the synthetic value, which does not ensure the entry of the synthetic silk into the center of the fiber ribbon. These drawbacks result in an uneven distribution of staple fibers at the periphery of the core, i.e. imperfect support of the staple fiber silk. This causes some of the surface of the synthetic silk core to not be stiffened with staple fibers, which in this case do not form a compact shell on the core. 231060

These drawbacks are eliminated by the proposed solution, which is the object of the invention, in that the pulley is adapted to be movable on the one hand in the direction of the shaft axis and on the other hand in the direction of the axle by the fixed arm and on the support arm an adjustable fastening part of the strand guide ribbon.

The proposed guiding device for the production of core yarns is universally usable for the span pitch, that the yarn guide and the synthetic silk guide pulley can be adjusted at a distance from the carrier. This device allows you to adjust the axis of the skid driver and the guide pulley. Other advantages of the proposed device are: the possibility of converting guiding elements depending on the weight of the material being processed, the possibility of changing the vertical setting of the pre-yarn guide, and also the possibility of deflecting this wire from the vertical position.

1 and (2), an adjustable support 1 is mounted on the conveyor bar of the spinning machine on which the guide guides are attached to the guide yoke. The support legs 2 are pivoted on this support 1 and the support legs 2 are supported on the support legs 2. the part 4 with the possibility of its spatial adjustment 4 is secured by a low matte 5. In the supporting part 4, a conductor 7 is fixed by means of a screw 7 In the lower part of the support, the arm 2 is a stone 11 which is adjustable in the groove of the support arm 2. The shaft 11 is screwed onto the shaft 8 by means of which it is possible to change the distance of the V-shaped groove of the guide roller 16 from the support arm 2. The shaft 8 is secured by a low nut 9 and washer 10. 12, enabling the rotary pulley 16, which is prevented from sliding on the bearing 12, is secured by a fuse 14, the inner ring of the bearing 12 is The bearing 12 is protected from the ingress of dust and other dirt by a washer 13 serving as a cover.

The guiding device is installed without the guiding rail of the doping machine so that the guiding pulley 16 with the truss. lay on 231,060 outlet pressure roller. The preload, unwound from the preload coil, enters through the guide eyelets to clamp the inlet pairs of the pulling rollers, the preloading conductors 7 adjacent to the yoke reins. The tension straps guide the elongated preload in the mold of the fiber strand until the exit pair of the folding rollers is clamped. A synthetic silk unwound from the roll is guided over the guide rods to the groove guide pulley 16 so that it engages the guide pulley 16 and is guided over the periphery of the exit pinch roller to clamp the exit pair of the pull rollers where the fiber strand enters the center .

The guiding device according to the invention can be used in the textile industry on ring spinning machines, and the current cost of introducing low, in addition to making the object of the invention is also possible in the own workshops of individual orcanizations.
