Buffer constant-tension device for online fiber unfolding and application method thereof

Abstract

The invention discloses a buffer constant-tension device for online fiber unfolding. The device comprises driving rollers, swing rollers and fixed transition rollers; center shafts of three sets of the driving rollers, the swing rollers and the fixed transition rollers are arranged in parallel, and are distributed in a triangular form, wherein the swing rollers comprises swing arm mandrels fixedlyarranged, swing arms rotationally connected with the swing arm mandrels, and swing roller bodies arranged at the end parts of the swing arms; tension detecting devices are fixedly connected with theswing arm mandrels for detecting pressure suffered by the swing roller bodies; and a control center is connected with the tension detecting devices and power sources of the driving rollers. The tension sensors are adopted to monitor the tension of material to unfold fibers in real time, and the tension is transmitted to the control center; and the control center adjusts the rotating speed of the driving rollers and the traction force of a traction device in real time, so that constant tension of the materials to unfold the fibers and synchronous speed with later procedures are realized, and the conditions of wire breakage, wire winding and the like are prevented.

Description

technical field [0001] The invention relates to the technical field of soft material processing, in particular to a buffer constant tension device for online fiber spreading and a use method thereof. Background technique [0002] In the process of carbon fiber online fiber spreading and knitting, it is necessary to realize the speed synchronization of the carbon fiber fiber spreading device and the warp knitting machine and the tension of all yarns when entering weaving. The existing online tension adjustment device for soft materials has a complex structure and slow response speed, and cannot realize constant tension control of online fiber spreading. [0003] In view of the defects of the above-mentioned existing constant tension control device, the inventor actively researches and innovates based on years of rich practical experience and professional knowledge engaged in the design and manufacture of this type of product, and cooperates with the application of academic th...
