Problems solved by technology

[0003] Although some domestic manufacturers have developed the drafting drive mechanism of ring spinning frame based on the servo control system in recent years, this mechanism still retains the drafting wallboard and the drafting conversion gear, and due to the high cost of the servo system, it cannot be solved. The problem of severed head after sudden power failure, so the mechanism has not been introduced to the market

Abstract

The multi-motor oil-free dry frame head and frame tail drafting drive system for ring spinning frame includes front roller motor, front roller gear box, middle and rear roller motor, middle and rear roller gear box, and three roller trains. The front roller motor is connected via a synchronizing belt to the front roller gear box, and the two output shafts of the front roller gear box are connected via synchronizing belts to the right and left front rollers separately. The middle and rear roller motor is connected via a synchronizing belt to the middle and rear roller gear box, and the four output shafts of the middle and rear roller gear box are connected via synchronizing belts to the right and left middle rollers and right and left rear rollers separately. The present invention adopts triphase permanent magnetic sync motor for driving and open-loop control, and has simple structure, smooth driving, high precision, easy regulation in spinning process and expanded technological application range.

Description

technical field [0001] The invention relates to a ring spinning frame, in particular to a multi-motor drafting transmission device for a headstock and a rear of the ring spinning frame. Background technique [0002] In the drafting transmission mechanism of the traditional ring spinning frame, the main motor at the rear of the car drives the main shaft, and the main shaft enters the front of the car through a series of gear meshes to drive the drafting mechanism of the front car. In long ring spinning machines with more than 600 spindles, a synchronous drafting mechanism at the rear of the car is added, which is driven by the front roller from the front of the car. In this mechanism, the driving source comes from the main motor at the rear of the car, and the spinning process adjustment is completed by a series of changing gears, which is inconvenient to operate, and due to the influence of its own structure, it cannot meet the requirements of some special processes. The ge...
