Abstract
The utility model relates to a wire beam broadening and positioning device for carbon fiber, which belongs to carbon fiber manufacturing equipment. The device consists of an original wire guiding roller, a wire roller, a limiting device, a broadening roller, a groovy roller, a positioning roller and a power guiding roller, which are arranged in sequence, wherein, the broadening roller is arranged at the upper part of the wire roller and is relatively parallel to the groovy roller, the positioning roller is arranged at the lower part of the groovy roller, the internal groove of the broadening roller is convex, certain distances are reserved among the rollers, and all the wirings wound among the rollers have certain rotating angles on the rollers. The wire beam broadening and positioning device can broaden wire beams, arrange the monofilaments in parallel, and ensure that the textile fiber is evenly heated in the carbonization process to improve the quality of products.
Description
Technical field
The utility model relates to the tow broadening positioner in the carbon fiber production line, and the broadening positioner especially for producing the 12K carbon fiber belongs to one of carbon fiber production equipment.
Background technology
Use the polyacrylonitrile fibre tow, when the tow of particularly using 12000 root polypropylene nitrile fibre single threads (being called for short 12K) to form is made the raw material production carbon fiber, because the cohesive force in the tow between each monofilament and the phenomenon that intersects, curls, cause the fiber inequality of in carbonisation, being heated, carbonization is incomplete, has influence on the mechanical property and the quality stability of final products.
Summary of the invention
The purpose of this utility model provides a kind of tow broadening positioner of carbon fiber,, can make fiber be heated inequality in carbonisation and improves the quality of products the tow broadening by this device.
The technical solution of the utility model is: a kind of tow broadening positioner of carbon fiber, it is characterized in that: by the precursor deflector roll, move back roll dies, stop, broadening roller, grooved roller, registration roller, power deflector roll and be arranged in order and form, wherein, the broadening roller is located at the top of moving back roll dies, and parallel relative with grooved roller, and registration roller is located at the below of grooved roller, broadening roller inside groove is a convex, maintain a certain distance between described each roller, the line between each roller of pile warp all has certain corner on each roller.
Advantage of the present invention is:
1, can improve the distributing homogeneity of precursor before entering carbide furnace, make between each monofilament to be arranged in parallel, guarantee the width unanimity of fiber, make carbon fiber product can be widely applied to the production field of preimpregnation cloth.
2, precursor is heated evenly in carbide furnace, and carbonization is abundant, and helps the volatilization of impurity, has improved the quality and the stability of carbon fiber.
3, avoided the appearance of fracture of wire and lousiness to a certain extent, this is because monofilament is arranged in parallel, and evenly distributes, and makes its suffered pulling force unanimity, and carbonizing degree is identical.
4, help the even starching of carbon fiber, its stress can effectively be transmitted and be evenly distributed, help the performance of carbon fiber high-strength characteristic.

1 precursor deflector roll, 2 moves back roll dies, 3 stops, 4 broadening rollers, 5 grooved rollers, 6 registration rollers, 7 power deflector rolls among the figure.
The specific embodiment
The tow broadening positioner of carbon fiber, by precursor deflector roll 1, move back roll dies 2, stop 3, broadening roller 4, grooved roller 5, registration roller 6, power deflector roll 7 and be arranged in order and form, wherein, broadening roller 4 is located at the top of moving back roll dies 2, and parallel relative with grooved roller 5, and registration roller 6 is located at the below of grooved roller 5, broadening roller inside groove be convex as shown in Figure 2, maintain a certain distance between each roller, the line between each roller of pile warp all has certain corner on each roller.
Connect by carbon fibre precursor between each roller during work, precursor tow one end is derived through the traction of power deflector roll, and the other end imports from moving back roll dies.Fiber makes the tow untwisting through moving back the tension force that acts on the tow when roll dies surface turns to, and has intersection, curling part to be straightened in the tow.Because the broadening roller is located at the top of moving back roll dies, there is certain height poor between two rollers, when moving on the fiber, at first be straightened, kept stretching state so enter the fiber of broadening roller, and in stop, moved, guarantee not job-hop from guide wheel of fiber.Because broadening roller inside groove is a convex, after fiber enters the broadening roller, make original some to be collected at together or the monofilament of close together is unfolded, broadening roller and the distance of moving back between the roll dies are long more, and the slope difference at monofilament two ends is more little, approaching more parallel between the monofilament, thereby helping the fiber broadening, broadening makes between each monofilament to be arranged in parallel after grooved roller, registration roller further evenly distribute, the location, the width unanimity forms regular tow band and enters carbide furnace.
Claims (1)
