Let-off tension bracket of carbon fiber cloth loom

Abstract

A let-off tension bracket of a carbon fiber cloth loom comprises a rack, a controller and a let-off roller, a pressing roller, at least two thread passing rods, a floating tension roller, a tension sensor, a tension motor and a let-off motor which are arranged on the rack, wherein a rotating shaft of the let-off roller is connected with an output shaft of the let-off motor through a conveyor belt; the at least two thread passing rods are arranged on an output side of the let-off roller sequentially; the floating tension roller is arranged between any two thread passing rods and can move vertically; the tension sensor is mounted on one side of the floating tension roller; an output of the tension sensor is connected with an input of the controller; the controller drives the thread passing rods to convey warps through the let-off motor; and the tension motor drives the floating tension roller to move vertically, so that the tension of the warps is adjusted. According to the let-off tension bracket of the carbon fiber cloth loom, a variable frequency motor is used for let-off and the tension sensor is used for measuring the tension of the warps, so that the bracket is free from influences of a back rest position and movement of mechanical components, and the tension of the warps is guaranteed to be consistent.

Description

technical field [0001] The invention relates to the textile field, in particular to a tension control system of a carbon fiber loom, in particular to a let-off tension frame of a carbon fiber loom. Background technique [0002] At present, most of the tension frames are driven by mechanical gears and chains. The warp let-off is uneven and the tension of the yarn is inconsistent, resulting in uneven tension on the entire cloth surface. The left side is tight and the right side is loose, or both sides are loose and the middle is tight, so it cannot be woven. As a result, the wavy shape of the carbon fiber cloth cannot be pre-impregnated. Contents of the invention [0003] The purpose of this invention is to solve the problem that the tension frame is mostly driven by mechanical gears and chains, the warp let-off is uneven, the tension of the yarn is inconsistent, and the tension of the entire cloth surface is easy to be uneven. , a let-off tension frame of a carbon fiber c...
