A twisted gauze rolling device

Abstract

The invention discloses a skein unwinding device, which comprises a driving mechanism, a tension monitoring mechanism located below the driving mechanism, a controller and a skein scaffolding, the driving mechanism and the tension monitoring mechanism are both connected to the controller, and the driving The mechanism is provided with a skein scaffolding, and the tension monitoring mechanism includes a mounting base, two fixed guide wheels, a moving guide wheel, a sliding rack, a driving gear, a driving shaft, a constant spring spring I, a casing, and three induction There are two fixed guide wheels and a slidably installed sliding rack on the outside of the mounting seat. Compared with the prior art, the phenomenon of broken or loose threads can be greatly reduced, and the structure is simple. Realize constant tension, easy to take yarn, adjustable peripheral diameter and convenient and quick adjustment.

Description

technical field [0001] The invention relates to the technical field of spinning machinery components, in particular to the technical field of a skein unwinding device. Background technique [0002] The speed control of the existing skein rack driving device generally monitors the tension of the skein through the tension sensor. When the tension value of the skein exceeds the specified value, the tension sensor sends a signal to the controller, and the controller controls the speed of the driving device. Increase, when the tension value of the skein is less than the specified value, the tension sensor sends a signal to the controller, and the controller controls the speed of the driving device to decrease. However, the above-mentioned tension sensor has a monitoring hysteresis factor. value, the tension value at this time is too large or too small, plus the system response time, it is still easy to break or loose the thread. [0003] The outer diameter of the existing hank c...

[0002] The speed control of the existing skein rack driving device generally monitors the tension of the skein through the tension sensor. When the tension value of the skein exceeds the specified value, the tension sensor sends a signal to the controller, and the controller controls the speed of the driving device. Increase, when the tension value of the skein yarn is less than the specified value, the tension sensor sends a signal to the controller, and the controller controls the speed of the driving device to decrease. However, the above-mentioned tension sensor has a monitoring hysteresis factor. value, the tension value at this time is too large or too small, plus the system response time, it is still easy to break or loosen the thread

[0003] The outer diameter of the existing hank creel is fixed, and it is necessary to use a hank creel of different diameters for different yarns or requirements. Therefore, a large number of hank creels are stored in spinning enterprises, occupying a large area. Space, especially due to the fixed outer diameter of the gallows, in the process of completing the skein, it is difficult to take the yarn due to the effect of the yarn pre-tightening force during the yarn taking process
