Constant-pressure shock absorption yarn guide

Abstract

The invention provides a constant-pressure shock absorption yarn guide which comprises a yarn guide body for guiding yarns. The yarn guide body is pivotally connected to one end of a columnar support, a columnar cavity is arranged at the other end of the columnar support, a plunger is arranged in the columnar cavity and is in leak-proof fit with the columnar cavity, a vent hole is arranged at the bottom of the columnar cavity, and a constant-pressure structure is arranged between the plunger and the columnar cavity. By the aid of the constant-pressure structure, constant pressure is kept between the plunger and the columnar cavity, the yarn guide body bearing the yarns can keep stable tension of the yarns on a transmission path, and the yarns are prevented from being strained.

Description

technical field [0001] The invention relates to the field of textile machinery and equipment, in particular to an automatic constant-pressure shock-absorbing yarn guide. Background technique [0002] The spinning process includes cleaning, loosening, opening, carding, combing, drafting, twisting and winding. During the twisting process of the yarn, the strands are twisted around their own axis, so that the fibers parallel to the axis of the strands are helical, thereby generating radial pressure to fix the longitudinal connection between the fibers, and the twisted yarn Wire semi-finished products or finished products are wound into a certain form to facilitate storage, transportation and processing in the next process. This process is called winding. The winding process should be carried out continuously on the basis of not affecting the output and quality of the product. Efforts should be made to realize the continuous production between each process and reduce the quali...

Problems solved by technology

[0003] Since the yarn transmission distance is relatively long during the entire yarn manufacturing process, the yarn transmission path of the same machine needs to be diverted by multiple yarn guides before being transferred to the winding device. It is not constant. Some yarns have higher surface friction and some have lower surface friction. As a result, the tension of the yarn in the transmission path is not constant when the yarn is transmitted. If the yarn tension is too high, the yarn will be strained, which requires The yarn guide has damping equipment. The damping of the existing damping equipment generally increases linearly. For example, the greater the damping range, the greater the damping, which affects the damping effect and makes the entire yarn transmission path The situation of uneven yarn tension on the
