Description

Twist reducing device

Technical Field

The utility model relates to an equipment technical field is woven to the yarn, especially relates to an untwister.

Background

Some yarns used in the knitting field are treated by a twisting process, and the yarn twisting process can enhance the strength of the yarns and improve the surface quality of finished cloth. Generally, the weaving process cannot be influenced by the small yarn twist, but the yarn winding and knotting phenomenon often occurs in the weaving process due to the large twist of the strong-twist yarn, and the quality of cloth can be seriously influenced if the yarn is not processed.

Currently, a twist reducer or a yarn gripper of a fixed support rod is generally adopted in the industry to reduce the twist of the yarn or increase the tension of the yarn.

The patent name of the Chinese utility model is retractable strong twist yarn detwister (with the publication number of CN 207452381U), which discloses a retractable strong twist yarn detwister, comprising a detwister shell, a detwisting ring and a plurality of support rods; the support rods are elastic and can be adjusted in size, length and number to accommodate bobbins of different sizes. The retractable strong-twist yarn untwister has the following defects: when the yarn cylinder is placed into the cone-shaped yarn cylinder, the yarn cylinder can be shaken, the yarn cylinder cannot be well fixed, and the risk that the yarn cylinder falls off can be avoided.

In order to achieve the above object, the utility model provides a twist with fingers ware, including subtracting the ware main part of twisting with fingers, twisting with fingers the wire ring loop, a plurality of bracing pieces, twisting with fingers the wire ring cover outside subtracting the ware main part, a plurality of bracing pieces constitute and support the umbrella, support the umbrella upper end and establish in subtracting ware main part lower part, its characterized in that: the opening radius of the upper end of the supporting umbrella is smaller than that of the lower end of the supporting umbrella, and the supporting rods forming the supporting umbrella can be attached to the inner wall of the conical spinning cylinder, so that the fixing firmness is increased.

In order to increase friction and reduce the twist of the yarn, the upper part of the twist reducer main body is provided with an upper edge, and the outer diameter of the upper edge is larger than the inner diameter of a twisted wire ring; the lower part of the twist reducing device main body is a circular trapezoid, the outer diameter of the upper bottom of the lower part of the twist reducing device main body is larger than the outer diameter of the lower bottom of the lower part of the twist reducing device main body, and the outer diameter of the upper bottom of the lower part of the twist reducing device main body is larger than the inner diameter of a twisted wire ring.

Furthermore, the supporting umbrellas are radially distributed at the lower part of the twist reducer main body.

In order to adapt to conical spinning drums with different gradients, the lower end of the twist reducer main body is provided with a knob, the knob can adjust and support the opening radius of the umbrella, the knob comprises a rotating screw part and an expanding cylinder, the rotating screw part is connected with the expanding cylinder, the outer diameter of the expanding cylinder is larger than that of the rotating screw part, and the rotating screw part can be screwed into the lower part of the twist reducer main body; the rotating expansion cylinder adjusts the depth of the rotating screw part entering the lower part of the twisting reducer main body, drives the expansion cylinder to pass in and out, and extrudes the inner wall of the supporting umbrella through the expansion cylinder to achieve the effect of adjusting the opening radius of the supporting umbrella.

The utility model has the advantages that: the twisting ring is sleeved outside the main body of the untwisting device, the supporting umbrella is formed by the plurality of supporting rods, the upper end of the supporting umbrella is smaller than the lower end of the supporting umbrella, the supporting umbrella is radially distributed, the supporting umbrella is supported in the conical spinning bobbin, the spinning thread penetrates through the untwisting ring to enter a knitting machine for knitting, the pressing tension of the untwisting ring acts on the yarn, the effect of reducing the yarn twist is achieved, the winding and knotting of the yarn are avoided, the conical bobbin can be fixed, the yarn can be prevented from swinging when the yarn is placed into the conical bobbin, the stable untwisting effect can be achieved for the fixed bobbin, and meanwhile, the conical bobbin with the opening radius capable of adapting to different slopes is adjusted and supported by the knob.
