An electronic yarn storage device

Abstract

The invention relates to the field of textile machinery and provides an electronic yarn storage device which comprises a motor, a shell, a yarn winding disc, a yarn storage barrel, a yarn outgoing tension adjusting device and a controller. The yarn winding disc, the yarn storage barrel, the yarn outgoing tension adjusting device and the controller are mounted on the shell, the yarn storage barrel is connected on the yarn winding disc in a sleeved manner, a support extends from the shell in a yarn outgoing direction of the yarn storage barrel, the yarn outgoing tension adjusting device is arranged between the support and one end, away from and connected with the yarn winding disc, of the yarn storage barrel, and the motor is in output connection with and drives the yarn winding disc to rotate; the electronic yarn storage device further comprises a first Hall sensor, a second Hall sensor, a photoelectric sensor, a first moving magnetic sheet mechanism, a second moving magnetic sheet mechanism and a reflector, and the controller comprise a main control circuit, a power supply circuit, a motor driving circuit, a three-phase direct-current motor driving circuit and a switch circuit. By the electronic yarn storage device, the problem that existing electronic yarn storage devices are high in manufacturing cost and unstable in yarn feeding which has impact on fabric quality is solved.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to an electronic yarn storage device. Background technique [0002] In textile production, the yarn storage device is an important part of the knitting machine. The yarn storage device mainly includes the housing, the main shaft and the wire delivery wheel installed on it. The yarn pressure ring and the tension ring are sleeved on the wire delivery wheel. At the center of the wheel, the main shaft drives the wire delivery wheel to rotate for yarn storage. The deficiencies existing in the existing yarn storage device are: 1. The motor rotates at the same speed from beginning to end during yarn storage. The yarn feeding speed and tension are different, while the yarn feeding speed of the yarn storage device is controlled by the tension ring, that is, the speed and tension of the yarn storage device are basically constant when the yarn is feeding, and the adjustment range is very smal...

AI Technical Summary

Problems solved by technology

The deficiencies existing in the existing yarn storage device are: 1. The motor rotates at the same speed from beginning to end during yarn storage. The yarn feeding speed and tension are different, while the yarn feeding speed of the yarn storage device is controlled by the tension ring, that is, the speed and tension of the yarn storage device are basically constant when the yarn is feeding, and the adjustment range is very small. The speed and tension of yarn feeding are inconsistent with those of yarn output, and the tension fluctuates greatly, thus affecting the quality of knitted products

Although the existing yarn storage devices can achieve precise control, they are all expensive, especially the cost of detection and control circuits is too high, which makes it impossible to effectively popularize the high-precision control yarn storage devices
