The present invention provides a tension adjusting apparatus comprising a fixing plate, a plurality of tension rollers rotationally connected with the fixing plate, a tension adjusting part and a plurality of guide rollers, wherein a friction sleeve is arranged at an exposed part of each tension roller; a plurality of friction sleeves are connected with one another through a steel belt; the tension adjusting part comprises an adjusting rack and an adjusting screw in threaded connected with the adjusting rack; one end of the adjusting screw is pivotally connected with a tensioning block; each guide roller is connected with the fixing plate through an elastic force measuring device; each elastic force measuring device comprises a fixed sleeve and a movable sleeve; mark scales are arranged on each fixed sleeve; each movable sleeve is assembled in one corresponding fixed sleeve in a sliding manner and is connected with the corresponding fixed sleeve through a spring; the exposed end of each movable sleeve is rotationally connected with one corresponding guide roller; sliding blocks matched with the mark scales are arranged on each movable sleeve. The tension adjusting apparatus has the beneficial effects as follows: the tension represented by each tension length of each spring is indicated by each sliding block; the tension adjusting magnitude can be accurately displayed; and the tension adjusting apparatus is simple in structure, easy to operate and convenient to maintain and wash.
Description
technical field [0001] The invention relates to the technical field of carbon fiber tension adjustment, in particular to a tension adjustment device. Background technique [0002] Cohen used the experimental design method to determine the effect of fiber prestress on the mechanical properties of the winding structure during the winding process, and found that increasing the prestress can effectively increase the fiber volume percentage of the winding layer in the fiber winding structure, thereby improving the strength of the structure. [0003] During the winding manufacturing process of composite components, a certain tension should be applied to the fibers. On the one hand, it is to arrange the fibers on the mold according to the design line, and on the other hand, it is to generate a certain prestress in the winding layer, thereby improving the resistance of the component. fatigue performance. [0004] The important reason affecting the performance of fiber strength is t...
