Problems solved by technology

However, this method has the following technical problems: 1. The tension of the tow cannot be guaranteed to be consistent for a long time. Although the adjustment accuracy of the rotating speed can reach 1 / 10,000, after a certain period of accumulation, the error will gradually increase, and the tension of the tow during travel It will change accordingly, or gradually increase, or gradually decrease; 2. The tow tension cannot be set and controlled according to actual needs
However, the disclosed technical solution is improved for the acrylic fiber cutting machine, which can only be applied to the acrylic fiber cutting machine, and cannot be applied to the field of carbon fiber tow tension control equipment. Therefore, it is urgent to develop a method suitable for carbon fiber production process. Tow tension control device in

Abstract

The invention discloses a tension control device for fiber tows. The tension control device comprises a first positioning roller, a second positioning roller, a tension roller, a guide device, a detection device, a controller and a motor speed regulator, wherein the guide device is used for guiding the movement of the tension roller; the detection device is used for detecting position change of the tension roller; the tension roller is positioned in a region between the first positioning roller and the second positioning roller; the axes of the tension roller, the first positioning roller andthe second positioning roller are parallel to one another; the tension roller is connected with the guide device; the detection device is used for feeding detection information of position change of the tension roller to the controller; and the controller is used for controlling the motor speed regulator to regulate the speed of a driving roller motor. By adopting the tension control device, the walking tension of carbon fiber tows can be regulated and controlled effectively, and carbon fibers with uniform and consistent quality can be produced; and the tension control device is suitable for large-scale industrial production, and has very good economic benefit and very wide application prospect.

Description

technical field [0001] The invention relates to the technical field of chemical fiber processing equipment, in particular to a fiber tow tension control device. Background technique [0002] In the carbon fiber production process, the oxycarbonization and post-treatment process refers to the process of oxidizing, carbonizing and post-processing polymer fibers, and processing them into carbon fibers under certain process conditions. Oxygen carbonization and post-treatment processes specifically include wire unwinding, humidification, oxidation, low-temperature carbonization, high-temperature carbonization, electrolysis, water washing, drying, sizing, drying, and wire collection. Equipment for carbonization, electrolysis, water washing, drying, sizing, drying, and fiber collection, as well as humidifying rolls, drafting rolls, godet rolls, electrolytic rolls, washing rolls, and sizing for pulling and transporting fiber tow in each process Traction rollers and guide rollers su...
