Automatic centering yarn drum positioning device for twisting machine

Abstract

The invention relates to the technical field of textile fabrics, and discloses an automatic centering yarn drum positioning device for a twisting machine. The device comprises a twisting machine body;the exterior of the twisting machine body is fixedly connected with a fixed shaft sleeve; the interior of the fixed shaft sleeve is fixedly connected with a first bearing; the interior of the first bearing is fixedly connected with a rotating shaft; the exterior of the rotating shaft is fixedly connected with a second bearing; the exterior of the rotating shaft is fixedly connected with a brake disc; the exterior of the twisting machine body is rotationally connected with a brake ring; the exterior of the brake ring is fixedly connected with a brake rotating wheel; the interior of the brake ring is fixedly connected with a convex block; the exterior of the twisting machine body is fixedly connected with a fixed block; and the exterior of the fixed block is connected with a brake sliding block in a sliding mode. A longitudinal fixed pay-off drum is changed into a transverse fixed pay-off drum through cooperative use of the rotating shaft and a positioning rod, so that the friction between threads and the pay-off drum is avoided and reduced, the threads are prevented from being damaged, and the quality of the threads is guaranteed.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to an automatic centering yarn drum positioning device for a twisting machine. Background technique [0002] In the fabric weaving process, it is usually necessary to twist the textile yarn in advance, and the twisting machine is a textile machinery equipment that twists multiple strands of spun yarn into one strand, and its function is to process the yarn or the combined strand yarn product into a linear shape. Products, thread for weaving and knitting, including twisting machine body and circuit part, the spindle outside the twisting machine body is connected with the motor output shaft of the circuit part, and the front end of the spindle is equipped with a connecting piece corresponding to the tap switch.

Problems solved by technology

[0003] In the prior art, when twisting, most of the pay-off cylinders are placed vertically on the twisting machine, but in this way, the pay-off cylinders will rub against the pay-off cylinders when the wires are unwound, which will easily cause the wires to break. Damage, and usually the pay-off drum is clamped by the bottom clamping device, but it will still vibrate due to centrifugal force during rotation, and the fixation is not firm, causing the pay-off drum to break away from the fixing device, thereby affecting the twisting efficiency, and in During the fixing process, because there is no centering device, the centering of the pay-off cylinder is not accurate, which may easily lead to the deviation of the axis, so that it is easy to vibrate due to eccentricity during the rotation process, which will affect the spinning efficiency and further increase the cost of the wire and pay-off. The friction of the barrel will increase the damage of the wire and affect the quality of the wire. At the same time, the pay-off drum that vibrates due to eccentricity will also easily cause knotting of the wire, which will easily cause the wire to break and affect the twisting efficiency. In addition, the existing twisting The machine pay-off device has no fixing device, which causes the pay-off drum to shake due to no fixing device during installation and taking, which increases the difficulty of installing and taking the pay-off drum.
