Head driving mechanism for flat knitting machine

Abstract

The present invention is head driving mechanism for flat knitting machine, and belongs to the field of knitting machinery technology. The head driving mechanism includes a DC motor controlled with the electric control box, a synchronous belt wheel fixed directly onto the power output shaft of the motor, a synchronous belt on the synchronous belt wheel, and a pulley slip fitting the track on the frame. The present invention adopts DC motor, rather than asynchronous AC motor, and has the advantages of easy installation, small size, raised safety and low power consumption.

Description

technical field [0001] The invention relates to a head drive mechanism of a flat knitting machine, which is an improvement to the existing head drive mechanism of a flat knitting machine, and belongs to the technical field of knitting machinery. Background technique [0002] The structure of the head drive mechanism of the flat knitting machine in the prior art is shown in Figure 2, and the motor 1 controlled by the electric control box (not shown) is installed on the frame 4, and the power output shaft of the motor 1 Fix the small pulley on 11, the small pulley is connected with the big pulley through the belt (triangular belt), the big pulley is installed on one end of the big pulley shaft (the right end in the figure), the big pulley shaft is set on the bearing seat, and the bearing seat is set on the frame 4, at the other end (the left end of the figure) of the large pulley shaft, fix the synchronous pulley 2 covered by the shield 21, the synchronous belt 3 is sleeved on...

AI Technical Summary

Problems solved by technology

The above-mentioned head drive mechanism mainly has the following deficiencies: one is that the motor 1 adopts an ordinary AC asynchronous motor, which has a large volume, a large temperature rise in the working process, easy heating, low power coefficient, and large energy consumption. It is necessary to install and use the above-mentioned motor 1. There are many transition parts, that is to say, a bridge needs to be passed between the motor 1 and the synchronous pulley 2, such as large and small pulleys, belts, large pulley shafts, and bearing seats, which makes the installation work cumbersome and not only for knitting horizontal The overall structure of the knitting machine is bloated, and the cost of the whole machine is greatly increased; the second is that it is difficult to shield large and small pulleys and belts (triangular belts) due to the frame, and there is a potential safety hazard. For example, once the yarn is entangled And, light will cause shutdown, heavy will cause motor burnout, etc., and for example, workers' limbs will cause accidents when they touch
