Reeled yarn unwinding device

Abstract

The invention discloses a reeled yarn unwinding device. The reeled yarn unwinding device comprises a drive mechanism, a tension monitoring mechanism located below the drive mechanism, a controller anda reeled yarn shed frame. The drive mechanism and the tension monitoring mechanism are connected with the controller. The reeled yarn shed frame is arranged on the drive mechanism. The tension monitoring mechanism comprises a mounting seat, two fixed guide wheels, a moving guide wheel, a sliding gear rack, a drive gear, a drive shaft, a constant-force spring I, an outer shell, three inductors andan inducted body. The two fixed guide wheels and the sliding gear rack capable of being mounted in a sliding manner are arranged on the outer side of the mounting seat. Compared with the prior art, the phenomenon of breaking or loosening can be greatly reduced, the structure is simple, constant-force tensioning is achieved, yarn can be taken easily, the peripheral diameter can be adjusted, and adjusting is convenient and rapid.

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 ha...

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
