Heating, extending and shaping device for woven carbon fiber unidirectional cloth

Abstract

The invention discloses a heating, extending and shaping device for woven carbon fiber unidirectional cloth. The heating, extending and shaping device comprises an unwinding device, a winding device,a heating and extending roller device and a shaping and cooling device, wherein the heating and extending roller device comprises multiple groups of heating rollers, and damping rotating shafts are arranged at two ends of the heating rollers; and the shaping and cooling device comprises multiple groups of shaping compression rollers used for shaping the high-temperature carbon fiber passing through the heating and extending roller device. Three groups of the heating rollers are arranged and are distributed triangularly. The heating and extending roller device and the shaping and cooling deviceare respectively used for performing heating and extending treatment and shaping and cooling treatment on the carbon fiber unidirectional cloth, so that carbon fiber warp yarn and hot melting yarn are closely combined. Three heating rollers are creatively arranged triangularly, and the carbon fiber unidirectional cloth is in contact with the heating rollers in a maximum area through reasonable cloth guiding layout, thereby achieving an optimal heating effect; and furthermore, the surfaces of high-temperature parts which are easily accessible to the human body are fully covered with the carbonfiber unidirectional cloth, thereby avoiding the scald caused by negligence during worker operation.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a heating fiber spreading and setting device for woven carbon fiber unidirectional cloth. Background technique [0002] Woven carbon fiber unidirectional fabric is a woven fabric in which carbon fibers are used as warp yarns and hot-melt yarns are used as weft yarns. In the production process of carbon fiber cloth, when the loom weaves carbon fiber warp yarn and thermal fuse weft yarn into carbon fiber cloth with overlapping structure of warp yarn and weft yarn, it is necessary to heat the carbon fiber unidirectional cloth to melt the sizing agent on the surface of the thermal fuse wire, and The carbon fiber warp yarn and the thermal fuse weft yarn are fixed into one while adding tension to spread the carbon fiber.

Problems solved by technology

[0003] The existing heating roller conventional method generally adopts heat conduction oil heating and electric heating. The biggest disadvantage of the heat conduction oil heating method is that it cannot avoid oil leakage and pollute the fabric, while the electric heating method uses carbon brushes to introduce heating power, and electric heating components It rotates with the roller. Since carbon fiber is a conductor, it is necessary to install a thick protective cover when using the carbon brush device in an environment with carbon fiber floating objects, otherwise it is unsafe. The device has a complex structure and consumes a lot of energy.

[0004] In addition, the temperature of the heated carbon fiber unidirectional cloth is relatively high, and the staff will inevitably come into contact with it in the actual production process. For example, when the yarn breaks and manual wiring is required, it will cause burns.
