Abstract

The yarn inserting and cotton feeding transmissino mechanism includes a yarn inserting speed controller comprising yarn inserting speed controlling frequency converter and yarn inserting speed programmer; and a cotton feeding speed controller comprising cotton feeding speed controlling frequency converter and cotton feeding speed programmer as well as independent right and left yarn inserting roller transmission mechanism, yarn inserting roller speed sensor, cotton feeding roller speed sensor and parameter display instrument. The output of the yarn inserting speed controlling frequency converter is connected to the input of the yarn inserting motor; and the yarn inserting roller speed sensor has output connected to the parameter display instrument.

Description

1. Technical field: [0001] The invention relates to a yarn drawing and cotton feeding transmission device of a rotor spinning machine, which belongs to a transmission system of a spinning machine. 2. Background technology: [0002] In the transmission mechanism of the existing rotor spinning machine, the transmission of the yarn drawing roller and the cotton feeding roller is respectively driven by an electric motor, and the respective transmissions are realized through a synchronous toothed belt, a gear box and a transmission shaft. The yarn take-off rollers and cotton feed rollers located on the left and right sides of the machine need to rotate in opposite directions through a gear box. Therefore, the design of the transmission mechanism of the rotor spinning machine is complicated, the transmission efficiency is low, and the manufacturing cost is high. The gearbox has a high failure rate, high noise, and inconvenient maintenance, which affects the improvement of spinning...
