Embodiment Construction

[0020] As shown in the accompanying drawing, the tension detection device in the running of the tow line adopts a set of support frames with a cantilever structure at both ends of the guide roller end face 3 before the tow 1 enters the crimping machine, and each set of support frames contains a connecting frame. Part 10 and a supporting part, the connecting part 10 and the roller are connected by a rolling bearing 4; the supporting part is fixedly connected on the spinning frame 7, and it is ensured that the corner 2 of the ribbon 1 is an obtuse angle of 150° when connecting; each supporting part has two Supporting feet 6, the length of a supporting foot 6 can be adjusted. An elastic full-bridge strain gauge 5 with a base length of 10 mm, a width of 5 mm, a sensitive grid length of 6 mm, and a detection range of 6-12 Newtons is also connected between the connecting part 10 and the supporting part of one group of supporting frames. The full-bridge strain gage 5 is then connecte...

Abstract

The invention discloses a tension detection device in the running of a tow line, which has a connecting part and a supporting part at both ends of a guide roller, and the obtuse angle of 145°-165° is used for the ribbon rotation angle. The connecting parts and the rollers are connected by rolling bearings, and the supporting parts are fixedly connected on the spinning frame. An elastic full-bridge strain gauge is also connected between one set of connecting parts and the supporting feet, and the stress N felt by it and the front tension F1 and back tension F2 in the ribbon can be calculated and displayed by detection methods . The invention can realize on-line measurement of the tension of the ribbon, real-time detection and timely discovery of abnormal problems, and contributes to the management and control of the production quality of the tow.

Description

technical field [0001] The invention relates to an online detection technology of tension in silk thread or tow. Background technique [0002] The tension in the existing fibers, silk threads, ropes or steel cables is often detected by tension fixtures. During the detection, the production operation needs to be stopped or the silk thread is running at a low speed. The detection cannot be continued during the entire production process, and the detection error is large. , the operation is inconvenient, and it may even easily lead to disconnection accidents. [0003] The Chinese patent application number is 032306261, which is a tow tension detection device used in the spinning process of chemical fiber filaments, including a lever-type pressing rod, a micro switch, a thread clamping groove and a bracket. The tail end of the lever-type pressing rod is connected to the bracket through a rotating shaft, and the micro switch and the thread slot are fixed on the bracket. The cont...
