Driving device of hank yarn shed frame

Abstract

The invention discloses a driving device of a hank yarn shed frame. The driving device comprises a driving mechanism, a tension monitoring mechanism which is located below the driving mechanism, and acontroller. The driving mechanism and the tension monitoring mechanism are controlled with the controller. The tension monitoring mechanism comprises a mounting seat, two fixed guide wheels, a movable guide wheel, a sliding rack, a driving gear, a driving shaft, a constant-force clockwork spring, a shell, three sensors and a sensed body. The two fixed guide wheels and the sliding rack which is capable of being slideably mounted are disposed on the outer side of the mounting seat; the movable guide wheel which is located in the rear of the middle of the two fixed guide wheels is disposed at the front end of the sliding rack; the sensors which are located below the sliding rack are disposed on the outer side of the mounting seat; and the three sensors are arranged in sequence from front toback. Compared with the prior art, the phenomenon of yarn breaking or loosening can be greatly reduced, the structure is simple, and constant-force tensioning can be achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of spinning machinery components, in particular to the technical field of a driving device for a skein scaffold. 【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. 【Content of invention】 [0003]...
