Twisting machine spindle brake

Abstract

The invention discloses a twisting frame spindle brake, which comprises a spindle brake block, wherein the spindle brake block is fixedly mounted on a brake rocking arm, one end of the brake rocking arm is hingedly supported, the other end of the brake rocking arm is provided with a rotatable tangential belt push tug, the brake rocking arm is further provided with a brake cylinder, the brake rocking arm is hingedly supported on the rail through a brake rocking arm hinged fulcrum, the brake cylinder is supported on the rail through a cylinder support, the brake cylinder is movably connected with the brake rocking arm through a brake rocking arm connecting piece. The twisting frame spindle brake has the advantages that the structure is simple, the brake is reliable and accurate, the automatic brake of a spinning device can be realized, and the brake is beneficial to improve the automatic degree of devices, which is widely applied to spinning devices such as twisting frames, doubling frames, compound twisting frames and spinning machines and the like.

Description

technical field [0001] The invention relates to a textile machine, in particular to a twisting machine and a parallel-twisting compound twisting machine, in particular to a spindle braking device of a twisting machine or a parallel-twisting compound twisting machine. Background technique [0002] Twisting machine or compound twisting machine is a textile machine that twists monofilament (yarn) through monofilament (yarn), merges and plies and twists into strands. The stress distribution of inner and outer fibers of single yarn after twisting is obvious Improvement, thereby greatly improving the overall performance of the yarn such as strength, evenness, abrasion resistance and appearance. [0003] Spindle is an indispensable and important part for twisting and winding of single yarn or ply in twisting machine or compound twisting machine. Because the spindle is always in the process of twisting and winding, there is always the phenomenon of yarn breakage, if the monofilamen...

AI Technical Summary

Problems solved by technology

Because the spindle is always in the process of twisting and winding, there is always the phenomenon of yarn breakage, if the monofilament or yarn breakage is not spliced ​​in time, not only twisting strands or a large amount of waste yarn will occur, It leads to a lot of waste of raw materials, and the winding of the yarn on the twisting or traction parts after the end is broken will also cause damage to the machinery and equipment, resulting in unnecessary waste and loss

[0004] After the yarn is broken, the spindle must be braked first, and then the broken yarn can be joined. At present, there are no more than two ways to brake the spindle: one of the most primitive methods is that the operator uses his hands to grab the high-speed rotating After the bobbin is spliced, this method of grasping the splicing with bare hands will not only cause contamination to the yarn, but also the high-speed rotating spindle bobbin is likely to cause burns to the hands of the operator, so this method is especially not suitable for large rolls. Installed in high spindle speed twisting machine

Another method is to directly push the brake device with the hand or its knee, so that the brake block bears against the spindle disc, and the spindle is braked by means of the friction resistance between the brake block and the spindle disc. This kind of manual braking On the one hand, the braking force of the device is unstable. Due to the influence of human factors such as individual operators and operator skills, it is difficult to achieve accurate and reliable braking, which is not conducive to the smooth operation of the spindle and the improvement of the service life; especially in the spindle system At the same time, the dragon belt or spindle belt driving the spindle rotation is still close to the spindle disk and slips on the spindle disk, which increases the braking force and energy consumption, and affects the stability and reliability of the spindle braking; on the other hand, this The brake device that is completely operated manually cannot realize the automatic monitoring and automatic operation of the textile machinery equipment, and cannot realize the digital control and modern management of the equipment, which restricts the improvement of the modernization level of the textile machinery equipment.

This manual braking device also has the disadvantages of long operating time and high labor intensity, which directly affects the improvement of equipment production efficiency; especially in the operation of the compound twisting machine, it is necessary to respectively twitch several Only the monofilament primary twist spindle, and then manually separate the traction pressure roller and traction roller, and finally brake the double twist spindle for ply twisting, the operation is very troublesome, labor-intensive and time-consuming
