A fiber spreading device and a fiber spreading method thereof

Abstract

The invention discloses a fiber expanding device and a fiber expanding method thereof. The fiber expanding device comprises a rack, a filament separating and yarn guiding mechanism is arranged at one end of the rack, a tightening transmission wheel is arranged on the portion, behind the filament separating and yarn guiding mechanism, of the rack, two tension roller sets are sequentially arranged on the portion, behind the tightening transmission wheel, of the rack, and a vibrating roller set is arranged between the tension roller sets; the vibrating roller set comprises vibrating rollers and vibrating devices arranged on the vibrating rollers and used for controlling vibration of the vibrating rollers, each vibrating roller comprises a main rotating roller which is located on the core part and is capable of rotating relative to the rack, and multiple fiber expanding rollers are connected to the outer surface of the main rotating roller in an annular matrix array mode; each tension roller set comprises a fixed roller installed fixedly and a movable roller capable of rotating relative to the rack, wherein a tension detecting device is connected to the fixed roller, heating devices are connected to the fiber expanding rollers, the fixed rollers and the movable rollers, and the surfaces of the fiber expanding rollers, the fixed rollers and the movable rollers are coarse. The fiber expanding device is capable of expanding fiber to be wide, thin and flat, simple in structure and convenient to maintain and saves space.

Description

technical field [0001] The invention relates to the field of fiber spreading in fiber prepreg production, in particular to a fiber spreading device and a fiber spreading method thereof. Background technique [0002] At present, fiber prepregs are more and more widely used in daily life. Tests on fiber prepregs show that the thinner the fiber prepregs, the smaller the mass per unit area, the smaller the deviation of their physical properties, and the better the operability of the covering. The better, therefore, the fiber spreading process of making fiber prepreg plays a vital role in the physical properties of fiber products. [0003] Such as the carbon fiber yarn spreading mechanism disclosed in the patent 2012102817766, such as figure 1 As shown, the yarn is transported to the heating fiber spreading device 30 through the wire device 20, and after the first fiber spreading of the yarn by the heating fiber spreading device 30, the synchronous driving device 40 drives the r...

[0003] Such as the carbon fiber yarn spreading mechanism disclosed in the patent 2012102817766, such as figure 1 As shown, the yarn is transported to the heating fiber spreading device 30 through the wire device 20, and after the first fiber spreading of the yarn by the heating fiber spreading device 30, the synchronous driving device 40 drives the roller fiber spreading device 50 to run, so that the yarn is stretched from The heated fiber spreading device 30 is sent to the roller fiber spreading device 50, and the yarn is secondarily spread by the roller fiber spreading device 50, and then the roller fiber spreading device 50 transports the yarn after the second fiber spreading to the tension balance fiber spreading device 60. The yarn is stretched for the last time through the tension balance fiber spreading device 60, so that the stretched yarn is conveyed to the next process, and the fiber can be widened, thinned and stretched through the above carbon fiber yarn spreading mechanism. Flattening, however, the structure of this kind of fiber spreading mechanism is very complicated, it takes up a lot of space, there are many internal devices, and the operation is complicated
