Double-row leather collar yarn guide assembly of ring spinning frame and ring spinning frame

Abstract

The invention discloses a double-row leather collar yarn guide assembly of a ring spinning frame. The number of middle roller sections and the number of rear roller sections are equal to the number oflower pins; the middle roller sections, the rear roller sections and the lower pins are distributed in a front-back correspondence manner according to the ratio of 1: 1: 1; the two adjacent middle roller sections are not directly connected; the two adjacent rear roller sections are also not directly connected; each middle roller section and each rear roller section can be detached; a middle roller and a rear roller which are adjacent to each other are not changed and moved; each middle roller section is driven by a middle roller transmission shaft; each rear roller section is driven by a rearroller transmission shaft; and a transmission path of each machine part of the yarn guide assembly is that the middle roller transmission shaft drives each middle roller section through a middle roller transmission gear, the middle roller drives a middle-upper roller and drives a middle-upper leather collar and a middle-lower leather collar to move at the same time, the rear roller transmission shaft drives each rear roller section through a rear roller transmission gear, and the rear roller drives a rear-upper roller and drives a rear-upper leather collar and a rear-lower leather collar to move at the same time.

Description

technical field [0001] The invention belongs to the technical field of spinning, and relates to a double row apron yarn drawing assembly of a ring spinning frame and the ring spinning frame. Background technique [0002] Both patents ZL201480019063.X and ZL201710327732.5 disclose a type of yarn-drawing assembly with double row aprons. In the assembly, the two lower aprons arranged side by side are fitted on the bottom rollers. To replace and install the lower aprons, the bottom rollers need to be disassembled. , in the double-row apron threading assembly, the circumference of the two lower aprons juxtaposed on the same spindle position is different, and the rollers of the snare are different. The long lower apron needs to be covered by two lower rollers. It is more difficult to install and replace the lower apron in the row apron yarn-drawing assembly. For this reason, the patent CN201822092749. Combination of supporting parts, for the two adjacent spindle positions, use de...

Problems solved by technology

[0002] Both patents ZL201480019063.X and ZL201710327732.5 disclose a type of yarn-drawing assembly with double row aprons. In the assembly, the two lower aprons arranged side by side are fitted on the bottom rollers. To replace and install the lower aprons, the bottom rollers need to be disassembled. , in the double-row apron threading assembly, the circumference of the two lower aprons juxtaposed on the same spindle position is different, and the rollers of the snare are different. The long lower apron needs to be covered by two lower rollers. It is more difficult to install and replace the lower apron in the row apron yarn-drawing assembly. For this reason, the patent CN201822092749. Combination of supporting parts, for the two adjacent spindle positions, use detachable supporting parts to hold the apron rollers of the two spindle positions, the lower roller drives the apron roller, and then drives the upper roller, although the disassembly of the lower apron is convenient , but the structure is very complicated. The middle roller and the rear roller frictionally drive the apron roller, and then indirectly drive the top roller. The installation error and transmission deviation between the spindles will affect the spinning index
