Upper rubber ring transmission twist-resistant jaw compact spinning device

Abstract

The invention provides an upper rubber ring transmission twist-resistant jaw compact spinning device. The device is composed of a drafting front jaw, a compact area, a twist-resistant jaw and the like; the compact area is arranged between the downstream part of the drafting front jaw and the twist-resistant jaw; the compact spinning device comprises a drafting front lower roller, a drafting front upper rubber roller, a twist-resistant upper rubber roller, an upper rubber roller frame, a lattice apron, a tensioner of the lattice apron, a negative pressure suction pipe, a plug of the negative pressure suction pipe and a pipe connecting opening, and is characterized in that the peripheries of the drafting front upper rubber roller and the twist-resistant upper rubber roller are annularly sleeved with a drafting compact rubber ring; and the lower part of the upper rubber roller frame is provided with a drafting compact rubber ring tensioner in corresponding to the lower part of the drafting compact rubber ring.

Description

technical field [0001] The invention relates to a compact spinning device attached to a ring spinning machine in spinning machines, in particular to a negative pressure airflow type compact spinning device using flexible compacting elements such as grid rings or rubber rings with holes. Background technique [0002] The large-scale industrial application of compact spinning technology has a history of about 20 years. It has become the most influential technological progress in the history of ring spinning technology development, and the application scale is constantly increasing. The domestic operating quantity has exceeded 30 million spindles and will continue to expand. In the application of domestic compact spinning devices, there are four major characteristics in terms of quantity: [0003] First, the number of transformations of stock spinning frames greatly exceeds the matching of incremental new machines; [0004] Second, the number of domestically produced devices ...

AI Technical Summary

Problems solved by technology

[0003] First, the number of transformations of stock spinning frames greatly exceeds the matching of incremental new machines;

[0004] Second, the number of domestically produced devices greatly exceeds that of imported devices;

[0008] The three-roller mesh ring negative pressure accumulation device is an accumulation structure that has been applied in China earlier, because the movement speed of the twist-stop nip depends on the ratio of the diameters of the top rubber roller and the twist-stop rubber roller before drafting, and the front Both the upper rubber roller and the anti-twisting rubber roller are specially made, and each spindle has a geared rubber roller core, so not only the investment cost is high, but also the anti-twisting rubber roller must be sharpened at the same time during the grinding and maintenance of the front upper rubber roller, so that the two The ratio of the outer diameter remains unchanged, so that the draw ratio of the accumulation tension remains unchanged, which not only increases the operation and maintenance cost but also brings troubles to the daily production management

[0010] It can be seen that the three-roller grid circle negative pressure accumulation device is greatly surpassed by the four-roller grid circle negative pressure accumulation device in terms of application market share due to the high operation and maintenance costs and the difficulty of daily management.

The four-roller mesh ring negative pressure accumulation device is a waste of money because it needs to replace and discard the original front bottom roller without gears, and it needs to add a special anti-twisting roller to increase investment costs.

[0011] In the prior art, the transmission structure of the twist-resistance nip and the grid ring in the three-roller and four-roller grid ring negative pressure accumulation device relies on the gear transmission mechanism of each rubber roller or each section of rollers, which not only increases The investment cost of the device is increased, and the operating cost of maintenance management is increased.
