In figure: 1 is that yarn outlet, 2 is that the first cord roller, 3 is that introducing cord roller, 4 is that warm table, 5 is that laser inductor, 6 is that suction head apparatus, 7 is that glue-spraying device, 9 is that the second cord roller, 10 is that the 3rd cord roller, 11 is the carbon fiber filament bundle for drawing cord roller, 8.
The specific embodiment
Below in conjunction with the specific embodiment of accompanying drawing to the broadening technique for carbon fibre tow, describe.
By reference to the accompanying drawings 1, a kind of apparatus for widen for carbon fibre tow, comprise yarn outlet 1, the first cord roller 2, introduce cord roller 3, warm table 4, suction head apparatus 6 and draw cord roller 7, described yarn outlet 1 is positioned at the below of the first cord roller 2, one side of the first cord roller 2 is provided with introduces cord roller 3, a side of introducing cord roller 3 is provided with warm table 4, and warm table 4 connects suction head apparatus 6, and suction head apparatus 6 one sides are provided with draws cord roller 7.
Draw cord roller 7 tops and be provided with glue-spraying device 8.
Draw cord roller 7 outsides and also be provided with the second cord roller 9 and the 3rd cord roller 10.
Introducing cord roller 3 is the cord roller of controlling with tension force.
Draw the cord roller of cord roller 7 for controlling with tension force.
The present invention is in tow broadening process, in continuous broadening process, large-tow carbon fiber introduces by the first cord roller 2 the introducing cord roller 3 that belt tension is controlled from yarn outlet 1, enter warm table 4, pass through subsequently the suction head apparatus 6 with laser inductor 5, then through glue-spraying device 8 typing, then draw cord roller 7 through what belt tension was controlled, then divide the wide-width flat carbon fibre tow that obtains broadening effect excellence via the second cord roller 9, the 3rd cord roller 10.
Utilize above broadening technique can realize the controlled of carbon fibre tow broadening technical process, under the condition of not destroying the tow structure, realize simultaneously the broadening typing of tow, obtain the broadening carbon fibre tow of stable performance excellence, the expansion of carbon fiber range of application and mechanical property are strengthened and play an important role.
Operation principle of the present invention and the course of work are:
The present invention mainly refers to by the revolution of introducing cord roller will have the carbon fiber filament bundle of some tension through warm table 4, 4 pairs of carbon fiber filament bundles of warm table 11 carry out thermoplastic makes its easy broadening, carbon fiber filament bundle 11 is by between special suction head apparatus 6 and laser inductor 5 afterwards, the carbon fiber filament bundle 11 of 6 pairs of processes of suction head apparatus has suction-operated, simultaneously the degree of depth of the carbon fiber filament bundle 11 that adsorbed by suction head apparatus 6 of 5 pairs of laser inductors can produce induction in order to can regulate in time introducing cord roller 2 and draw the velocity ratio of cord roller 7, reach the degree of depth of feedback regulation suction head apparatus 6 absorption tow, when carbon fiber filament bundle 11 adsorbs and stretches after separating again by drawing cord roller 9 outputs through suction head apparatus 6, now carbon fiber filament bundle 11 stretches, the carbon fiber filament bundle 11 stretched through 8 pairs of broadenings of glue-spraying device of drawing correspondence on cord roller 7 carries out the glue spraying typing, finally by the second cord roller 9, the 3rd cord roller 10 is derived the wide-width flat carbon fibre tow that obtains broadening effect excellence.This technical process is simple, easy to operate, and what mainly solve is the broadening problem of carbon fiber filament bundle, provides convenience to the processing of follow-up composite product.Specific as follows:
1, the present invention be at the carbon fiber filament bundle, make when drawing the yarn roller its after stretch process in realize broadening, and utilize laser inductor feedback regulation tow width, make whole technical process controlled.
2, the present invention can obtain the flat tow of broadening of stable performance, also through glue spraying, finalizes the design and makes its broadening form keep stable through the broadening tow of adsorbent equipment and laser inductor.
3, the broadening tow that obtains of the present invention is used in the composite product aspect and can greatly improves its performance, alleviate its quality, and improve outward appearance, to fields such as the high Aero-Space of material performance requirement, physical culture, automobile and industrial goods, also put it over just rapidly.
