Control device of warp-sending tension of carbon fiber weaving machine

Abstract

The invention relates to a control device of a warp-sending tension of a carbon fiber weaving machine and belongs to the technical field of the carbon fiber weaving machine. The control device for the warp-sending tension of the carbon fiber weaving machine comprises a rear beam tension roller, wherein stirring pin holes are arranged at lower parts of rear beam rocker arms at two shaft ends of the rear beam tension roller; stirring pins are inserted into the stirring pin holes; the stirring pins are arranged in stirring pin slots at the middle part of an arc rocker arm; the upper end of the arc rocker arm is hinged with an arc rocker arm shaft; an arc rocker arm connecting rod hole is arranged at the lower part of the arc rocker arm; one end of a connecting rod is hinged in the arc rockerarm connecting rod hole; the other end of the connecting rod is hinged in a crank connecting rod hole at the lower end of a crank; the middle part of the crank is fixedly connected with the shaft endof a crank rotating shaft; an oscillating arm is also fixedly mounted at the shaft end of the crank rotating shaft; the lower end of the oscillating arm pushes against the outer side of a front spring base of a spring device; a tension sensor which is used for detecting spring tension and sending a signal to a control system is mounted on a rear spring base; and a spring is mounted between the front spring base and the rear spring base. The control device is simple in structure, flexible in operation, convenient in manufacturing and stable in warping tension.

Description

technical field [0001] The invention relates to a carbon fiber loom, in particular to a let-off tension control device for a carbon fiber loom. Background technique [0002] The carbon fiber loom includes a shedding mechanism, a weft insertion mechanism, a weft beating mechanism, a let-off mechanism and a take-up mechanism. The shedding mechanism drives the heald frame to move up and down so that the warp yarns form a shed. The weft mechanism drives the reed to drive the weft yarn entering the shed mouth into the weaving mouth to weave into cloth. [0003] The let-off mechanism is equipped with a let-off tension control device. The let-off tension control device includes a back beam tension roller. Both ends of the back beam tension roller are installed on a movable bracket. And adjusted, the carbon fiber warp passes around the back beam tension roller and forms the wrap angle. When adjusting the tension, the backrest tension roller moves accordingly to change the wrap ang...
