Technical Field

The invention belongs to the field of textile machinery, and particularly relates to an adjustable single suction nozzle device for broken end cotton suction of a high-speed ring spinning frame.

Background

Spun yarn is one of important processes in spinning production, and the quality of the spun yarn produced by the spun yarn directly influences subsequent products. The cotton suction flute pipe is one of important components of the broken end cotton suction device of the spinning frame, is positioned at the foremost end of a cotton suction line, and provides stable air suction airflow for a twisting working area under the negative pressure power of a high pressure fan. Under the same other conditions, the fiber strands are quickly and effectively continuously sucked into the air pipe, the adjacent yarns are prevented from being broken by the ribbon, the broken end suction rate is improved, and the flaws are reduced. At present, cotton sucking flute pipes with pear-shaped cross sections are widely adopted, six spindles are arranged one by one, and one air suction opening is arranged one by one, the structure is simple, the manufacturing cost is low, along with the continuous progress of the spinning technical requirements, the ultra-high speed and ultra-long spindle number becomes the mainstream of the development of spinning equipment, and the negative pressure loss is more serious the farther away from a fan in the longitudinal direction. Meanwhile, the development trend of upgrading the transmission of 6 ingots/sections of rollers to 8 ingots/sections of rollers is gradually remarkable due to the continuous improvement of the machining level, so that the installation requirement of high speed and efficiency is met, the cost is reduced, the length of a flute pipe is correspondingly increased along with the increase of the length of the rollers, the positions of suction inlets of each ingot are not adjustable, and the equipment requirement cannot be met. In order to solve the problem of negative pressure attenuation, increase the air suction effect, improve the sectional area of the air pipe, and simultaneously replace a cotton suction flute pipe by adopting a single suction nozzle cotton suction mode, the negative pressure is relatively consistent, the air flow suction distribution of the suction holes is favorably more effectively covered on the fiber strips discharged by the front roller, the cotton suction capacity of the cotton suction pipe is greatly improved, and the broken ends are reduced. However, the single suction nozzle used at present is connected and positioned with the air pipe close to the air pipe connecting pipe, the air pipe connecting pipe is a rubber piece, and the flexible connection cannot guarantee the position fixation with the front roller, so that the position of the cotton suction area is unstable.
