The specific embodiment

Below in conjunction with accompanying drawing the present invention is done and to describe in further detail.

Shown in Fig. 1～5, a kind of carbon fibre stretching device, comprise support 1, creel 1 ', bobbin cradle 5, pressure roller 6, first cord roller 7, locating guider 8, second cord roller 9 ', the 3rd cord roller 9, the 4th cord roller 11 and milling roller 10, described creel 1 ' is installed on the support 1, described bobbin cradle 5, the pressure roller 6 and first cord roller 7 are contained on the creel 1 ', second cord roller 9 ', the 3rd cord roller 9, the 4th cord roller 11 and milling roller 10 equal rotational support are on support 1, described locating guider 8 is installed on the support 1, between the 3rd cord roller 9 and the 4th cord roller 11, also be provided with at least two warm-up mills 2 and at least one dancer rools 3, the roll shaft two ends of described warm-up mill 3 all are supported on the support 1, be equipped with on the described support 1 and regulate support 4, described dancer rools 3 can be fastened on with adjusting up and down to be regulated on the support 4, dancer rools 3 can move up and down along regulating support 4, and milling roller 10 is positioned at the rear of the 4th cord roller 11.

Select three warm-up mills 2 and two dancer roolss 3 in the present embodiment for use.

Described dancer rools 3 is the heat regulation roller.Dancer rools 3 also can be the conventional roller that does not heat.

Shown in Fig. 3,4,5, described adjusting support 4 has chute 4-1, and screw 12 is equipped with in the end of described dancer rools 3, and screw 12 passes chute 4-1 and dancer rools 3 and adjusting support 4 are fixed.The diverse location that is fixed on chute 4-1 by screw 12 is regulated the distance of dancer rools 3 and warm-up mill 2, and is simple in structure, easy to operate.

As shown in Figure 3, described chute 4-1 is a rectangle.

As shown in Figure 1, 2, described per four locating guiders 8 constitute one group, one second cord roller 9 of every group of locating guider 8 difference correspondences ' and, per two second cord rollers 9 ' one the 3rd cord roller 9 of correspondence.

As shown in Figure 1, 2, described milling roller 10 has three, and one of them milling roller 10 is positioned at the centre position of the below of two milling rollers 10 in addition.

As shown in Figure 1, 2, 3, described dancer rools 3 is positioned at the below of warm-up mill 2, and between two adjacent warm-up mills 2

As shown in Figure 4, described warm-up mill 2 comprises roll shaft 2-1 and roller shell 2-2, and described roll shaft 2-1 is an electrical bar.Certainly the structure of warm-up mill 2 also can be to add heating wire in the roller.

Described locating guider 8 has several, from top to bottom arranges, and adjustable position between the adjacent locating guider 8.Locating guider 8 can guide the trend of carbon fiber.

Pressure roller 6 of the present invention, cord roller 7,9 ', 9,11 surfaces are all through ion Plasma Nitriding Treatment, make pressure roller 6, cord roller 7,9 ', 9,11 top layer quality densification, toughness and tenacity have both.Bobbin cradle 5, pressure roller 6, cord roller 7 is fixed on the conplane support 1, carbon fibre thread is contained on the bobbin cradle 5, carbon fiber is pushed down by pressure roller 6, can not twist during with the assurance unwinding, after carbon fiber comes out from pressure roller 6, through one first cord roller 7, to locating guider 8, locating guider 8 main effects are fixed carbon position of fibers, guarantee in the fine process of the exhibition of back, to avoid moving about about carbon fiber, bundle with restraint between overlapping, separate, guarantee all even presentation quality of mass area ratio of fabric, after the carbon fiber fixed-site through twice second cord roller 9 ', the 3rd cord roller 9, enter between warm-up mill 2 and the dancer rools 3 three warm-up mills 2, two Height Adjustable heat regulation roller 3 co-operation, warm-up mill 2 passes through bearing fixing with dancer rools 3, all rotatable, avoid carbon fiber by the time reduce because of friction causes lousiness and performance.The main effect of warm-up mill 2 is that solid-state carbon fiber surface sizing agent is dissolved, make the carbon fiber monofilament to move freely within the specific limits, rearrange, heating surface area by two dancer roolss, 3 adjusting carbon fibers, the dancer rools 3 that can regulate heating is to adjusted, carbon fiber and each warm-up mill 2 contacts area increase, heating surface area also increases, the carbon fiber surface sizing agent degree of dissolving uprises, the carbon fiber monofilament is diminished by the binding force of sizing agent, carbon fiber monofilament locomotivity is strengthened, moving of carbon fiber monofilament, it is just easy more to arrange, so the also easier broadening of carbon fiber.The carbon fibre fabric mass area ratio is more little, amount of carbon fiber in the unit are is also just few more, it is even as far as possible that this just requires that carbon fiber can approach as far as possible, distribute, in this case, just require the contact area of carbon fiber and warm-up mill 2 big as far as possible, to increase the width of carbon fiber, only need two dancer roolss 3 that can regulate heating are raised and get final product, do the heavy fabric operation of mass area ratio in contrast, simple to operate, convenient.Open up fine mode by this heating and can put on display the required carbon fiber width of mass area ratio that difference requires fabric.Heating exhibition is fine finish after through the 4th cord roller 11 together, enter carbon fiber milling roller 10, the main effect of milling roller 10 is that the fine good carbon fiber of heating exhibition is further opened up fibre, operation principle is: the carbon fiber that the surface infiltration agent is not cooled off as yet fully rolls, by the pressure between the milling roller 10,, proper alignment further even toward width the monofilament of carbon fiber, thus reach the fine purpose of cal rolling exhibition.Because milling roller 10 is an aluminium material matter, heat conduction is very fast, after-heat on can very fast absorption carbon fiber in time solidifies the sizing agent of carbon fiber surface, makes carbon fiber enter woven extent through several roads cord roller at last and is woven into cloth or makes carbon fiber warping coiled hair through warping machines.
