An Air Chamber Structure for Reducing Vacuum Absorbing Negative Pressure Fluctuation of Rotor Spinning Machine

Abstract

The invention relates to an air compartment structure capable of reducing negative-pressure fluctuation of impurity suction of a rotor spinning machine. The air compartment structure comprises an air compartment, the front end of the air compartment is connected with an impurity suction air pipe, the rear end of the air compartment is connected with an impurity suction fan, a left filter screen, a right filter screen and a middle partition are fixedly mounted in the air compartment and divide the same into a front portion and a rear portion, and a front half portion of the air compartment is an impurity collection box. The front side face of the middle partition is fixedly connected with a separator, a left filter screen partition and a right filter screen partition are hinged to the left end and the right end of each filter screen, connecting rods are hinged to the middles of the left filter screen partitions and the right filter screen partitions, and the other end of each connecting rod penetrates out of the side wall of the air compartment and is provided with a handle. The air compartment structure is beneficial to impurity deposition, and covered time of the filter screens is prolonged. When an air duct is switched, change of ventilation area is only one half of that of the structure in the prior art, negative-pressure fluctuation is reduced by one half correspondingly, and yarn quality is improved beneficially.

Description

technical field [0001] The invention relates to an air chamber structure of a rotor spinning machine, in particular to an air chamber structure for reducing the fluctuation of the miscellaneous suction negative pressure of the rotor spinning machine, and belongs to the technical field of spinning equipment. Background technique [0002] At present, in the air suction type rotor spinning machine that actively absorbs impurities, the impurities in the carding cavity are removed by a suction fan. The filter screen isolates and collects impurities. The air chamber is equipped with a conversion channel. Before removing impurities, switch the miscellaneous suction air duct to the conversion channel, so that the miscellaneous suction air duct is isolated from the miscellaneous box, and then switch to the working state after the impurities are removed. [0003] Such as figure 1 Shown: the air chamber of the prior art is vertically installed with a main filter screen 7 and a second...

AI Technical Summary

Problems solved by technology

The fluctuation of negative pressure has great influence on yarn quality

[0009] 4. Since a conversion channel needs to be reserved in the upper part of the air chamber, and the height of the miscellaneous box is limited by the space of the machine, and the depth is limited by the length of the arm when manually removing impurities, the usable space of the miscellaneous box is relatively small, and manual removal of impurities high frequency
