Description

TECHNICAL FIELD

[0001] The present application relates to the field of components of a twisting machine, in particular to an energy-saving balloon ring for ultra-fine fibers. BACKGROUND

[0002] The twisted yarn is driven by the twisting assembly to rotate outside the spool can to form a balloon, as shown in Figure 11 The size of the balloon has a great influence on energy consumption and product quality, too large balloon diameter causes the energy consumption of the twisting machine to rise sharply, and too large balloon may touch the yarn separator plate or wall plate, causing excessive yarn strength loss or even yarn breakage; too small balloon may cause yarn friction with the spool can, resulting in yarn breakage, lint phenomenon, affecting product quality and full spool rate of the equipment. The balloon ring is a special component on the straight and doubling twister, the balloon ring is arranged outside the outer ring of the spool can, which can effectively control the distance of the yarn balloon from the spool can during twisting, reduce the radial size of the yarn balloon, thereby reducing energy consumption and noise; in addition, it is also beneficial to reduce the tension of the yarn in the balloon part and reduce yarn breakage; it can also reduce the fluctuation of the balloon, making the balloon operate more stably. Chinese patent document CN104073935A describes a doubling balloon cover with a convex ring, the balloon cover is circular in any cross section, but in this structure, the yarn of the outer yarn balloon forms multiple-point contact with the balloon cover, resulting in excessive yarn strength loss or even yarn breakage. CN215976198U describes a yarn balloon control unit for a textile machine, which adopts a spiral structure. The problem with this scheme is that the outer yarn of the outer yarn balloon is also in spiral motion, when the outer yarn balloon is limited by the balloon control ring, the outer yarn deforms by a partial wrap angle on the inner wall of the balloon control ring, when the outer yarn passes through the spiral position, the outer yarn forms a convex and concave structure, which easily leads to excessive yarn strength loss or even yarn breakage due to abrasion. Ultra-fine fibers refer to fibers with a single filament fineness of less than 0.44 dtex, ultra-fine fibers have many excellent properties, including fine hand feeling, wrinkle resistance, high density, good warmth retention, and better water and oil absorption. The materials include polyamide, polyester, polypropylene, polyacrylonitrile, etc. However, due to the small single filament fineness, the production efficiency is extremely low, and increasing the twisting speed easily leads to yarn breakage of the ultra-fine fibers.
