Abstract
The invention discloses a multi-roller carbon fiber transmission and redirecting device which comprises a fixed shaft and n redirecting rollers (n is larger than 1), wherein the n redirecting rollers are in coaxial sleeve joint with the fixed shaft through a bearing and varies in diameter, and every two adjacent redirecting rollers are in clearance fit; fiber wiring troughs are respectively circumferentially formed in the side walls of the n redirecting rollers; each fiber wiring trough has an arc bottom surface and two sides respectively inclined outwards, and the bottom surface and the two sides are in round corner transition. The multi-roller carbon fiber transmission and redirecting device has the advantages that to the utmost, n fibers can be transmitted at the same time without mutual interference, and the amount of the fibers for transmission can be flexibly selected. Moreover, the harm to the fiber during the transmission process is reduced, so as to reduce the phenomenon of fluffing, breaking and the like.
Description
Technical field
The invention belongs to technical field of composite material molding, is a kind of multi-thread roller carbon fiber transmission diverter.
Background technology
Carbon fibre composite has excellent mechanical property, and therefore more and more extensive in the application of aerospace field and civil area, wrapping machine is the important former of carbon fibre composite.
The fiber conduction deviator of existing wrapping machine adopts pilot hole deviator more, in fiber conductive process, needs the position of break-in that pilot hole is set, thereby fiber changes the trend of fiber along the conduction of pilot hole hole wall.
Carbon fiber has the shortcomings such as axial modulus of shearing is low, fragility large, dispersion of materials performance is large, interlaminar strength is low, adopt existing fiber winding machine to carry out in carbon fiber winding forming process, owing to adopting pilot hole deviator, it between pilot hole and fiber, is sliding friction, thereby cause that fiber easily occurs that wearing and tearing, fluffing, fracture of wire, sudden strain of a muscle gap etc. affect the phenomenon of carbon fiber product mechanical property when through pilot hole deviator, cause poor product quality, life-span low.
Summary of the invention
In order to address the above problem, the present invention proposes a kind of multi-thread roller carbon fiber transmission diverter, can meet the break-in simultaneously of six bundle fibers simultaneously, and separate between every bundle fiber, do not interfere with each other, reduce to damage in fiber conductive process, reduce the problems such as carbon fiber fluffing, broken string, guarantee the Wrapping formed quality of high modulus carbon fiber fibre.
The multi-thread roller carbon fiber of the present invention transmission diverter, comprises dead axle and break-in roller.Wherein, break-in roller is n, n > 1; N break-in roller is socketed on dead axle by coaxial bearing; Two break-in clearance between rolls adjacent in n break-in roller coordinate, and the diameter of n break-in roller is all not identical, thus can be when fiber conveying, guarantee fiber in follow-up conductive process in conduction roll shaft to diverse location, while preventing that multiple fibre from conducting simultaneously, fiber intertwines.The sidewall week of n break-in roller upwards all has fiber trough; Fiber trough bottom surface is arc surface, and two sides are respectively outward-dipping, and between the bottom surface of trough and two sides, are that fillet is excessive, fiber is caused to damage when reducing fiber conveying.
The invention has the advantages that:
(1) the multi-thread roller carbon fiber of the present invention transmission diverter, can meet maximum bundle fibers simultaneously and conduct simultaneously, and the conduction of every bundle fiber is non-interference, can select flexibly the quantity of Conductive fiber;
(2) the multi-thread roller carbon fiber of the present invention transmission diverter, can reduce the damage to fiber in conductive process, thereby subtracts the phenomenons such as fibrillose fluffing, fracture of wire;
(3) the multi-thread roller carbon fiber of the present invention transmission diverter, can prevent that fiber access to plant is inner, and device long service life, avoids safeguarding;
(4) the multi-thread roller carbon fiber of the present invention transmission diverter, the structure that adopts bearing to connect, break-in roller goes slick.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
A multi-thread roller carbon fiber transmission diverter, comprises dead axle 1 and break-in roller, as shown in Figure 1.
Wherein, break-in roller is n, n > 1; N break-in roller is socketed on dead axle 1 by coaxial bearing; N break-in roller 2 borings, and one end is blind end, the other end is openend; Blind end adopts thin-wall construction, and wall thickness is 1～2mm, and then effectively alleviates construction weight.
Sidewall week of n break-in roller upwards all has fiber trough 3, when fiber transmits along trough 3, can position fiber, and when fiber passes through trough 3, the tension force of fiber force fiber to both sides even opening, to optimize fiber distribution.
Described fiber trough 3 degree of depth are 6～8mm, and bottom surface is arc surface, and two sides are outward-dipping respectively, and angle of inclination is identical, is 10 °～13 °; And be that fillet is excessive between the bottom surface of trough 3 and two sides, radius of corner is 1～1.5mm, fiber is caused to damage when reducing fiber conveying.
The diameter of described n break-in roller is all different, thus can be when fiber conveying, guarantee fiber in follow-up conductive process in conduction roll shaft to diverse location, while preventing that multiple fibre from conducting simultaneously, fiber intertwines.N the break-in roller 2 designing in the present invention on dead axle 1 increases progressively equal length m by dead axle 1 one end successively to the other end, and m is 6～8mm; Thus, can guarantee fiber in follow-up conductive process conduction being axially uniformly distributed of roller, guarantee the crudy of follow-up processing technology (such as gel content control, tension force control etc.).
Make two break-in rollers adjacent in n break-in roller 22 for break-in roller A and break-in roller B; The openend week of the blind end of break-in roller A and break-in roller B is the ledge structure matched in clearance of design upwards.
In a said n break-in roller 2, on blind end end face, have lightening hole, further alleviate construction weight; The quantity of lightening hole is directly proportional to the diameter of break-in roller 2.
In the present invention, n break-in roller 2 all adopts abrasion-proof stainless steel processing, increases the service life of parts.
