Abstract

The invention relates to the technical field of textile machinery, and provides a constant-tension yarn feeder. The constant-tension yarn feeder comprises a single-chip microcomputer control circuit,a rotary encoder, a first magnet, a motor for feeding super yarn, a motor drive control circuit, a display screen, a tension setting circuit, a power supply circuit and a yarn tension detection device, the yarn tension detection device comprises a base, a lever arranged on the base, a second magnet, a spring and a Hall sensor, the Hall sensor detects yarn tension compression pressure of yarn feeding in real time and sends the yarn tension compression pressure to the single-chip microcomputer control circuit, the rotary encoder divides a motor shaft of the motor into 4096 parts after rotating for one circle and 360 degrees, accurately identifies the rotation angle of the motor shaft of the motor and the real-time position of a motor rotor by sensing the first magnet, and sends the rotationangle and the real-time position to the motor driving control circuit; the single-chip microcomputer control circuit controls the speed of the motor through the motor drive control circuit to adjust the tension of the yarn. The constant-tension yarn feeder solves the problem that an existing constant-tension yarn feeder cannot effectively achieve tension balance control yarn feeding.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a constant tension yarn feeder. Background technique [0002] In textile production, as we all know, the yarn feeder is an important component mechanism in the yarn production equipment, which is used to transport the yarn. However, the yarn feeder in the prior art cannot adjust the conveying speed according to the tension of the yarn in real time, thus affecting the yarn forming quality. There are also some advanced yarn production equipment on the market that use coordinated control of tension sensors, motors and overfeeding mechanisms to adjust yarn tension. However, the tension sensor, motor and overfeeding mechanism need to be installed separately, which has low integration and takes up a lot of space; and the sensitivity of the tension sensor is poor, the tension measurement is inaccurate, and the yarn tension detection and the real-time adjustment control of the...
