Description

Double belt press device {A APPARATUS OF DOUBLE STEEL BELT PRESS}

The present invention relates to a double belt press apparatus, and more particularly, to a double belt press apparatus in which a steel belt used in the apparatus can be easily mounted and exchanged, and carbon fiber fabrics produced are uniformly bonded without bubbles.

Continuous fiber-reinforced plastics contain reinforcing fibers such as glass fibers or carbon fibers in a continuous phase in plastics with relatively weak mechanical strength. It has very good mechanical strength, stiffness and impact performance compared to long-fiber-reinforced plastics at the 5-50 mm length level, such as reinforced thermoplastics) or Long Fiber-reinforced Thermoplastics (LFT) or Glass Mat-reinforced Thermoplastics (GMT).

In addition, continuous fiber-reinforced plastics should be able to be woven in one or both directions due to excellent flexibility, and the continuous fiber-reinforced plastic structures woven through this can be applied to products requiring various mechanical performance.

The continuous fiber-reinforced plastic is typically manufactured by a Pultrusion method or a Commingle followed by a Hot Pressing method. The pultrusion method is to impregnate the continuous fiber bundle with a plastic resin by passing the widely spread continuous fiber bundle through a liquid (or molten) resin bath or die. However, there are disadvantages in that it is difficult to control the content of reinforcing fibers (continuous fibers) and plastic resin, and it is not easy to weave due to poor flexibility.

The hot pressing method following the mixed spinning (Commingle) is a method of mixing and spinning continuous fibers and a plastic resin in the form of fibers, and then hot pressing them. Due to the physical combination of the plastic resin and the plastic resin, the flexibility of the fibers is not greatly lost, so it is easy to weave. bad

However, in the case of hot pressing after weaving, because the plastic resin is randomly mixed in the continuous fiber bundle, in the hot pressing method following the mixed spinning (Commingle), partially sufficient impregnation does not occur, the uniformity of physical properties is lowered, and the fiber There is a disadvantage in that it is limited to thermoplastics having sufficient elongation properties in relation to processability when made into a shape.

Next, the upper roller rotating part 183 is configured to install the upper pressure roller 181 to the upper installation frame 134 and rotate the upper pressure roller 181 as shown in FIGS. 4 and 5 . element, and the lower roller rotating part 184 is a component that installs the lower pressure roller 181 on the lower installation frame 144 and rotates the lower pressure roller 182 .

Next, as shown in FIGS. 4 and 5 , the roller spacing adjusting unit 185 is installed in the upper roller rotating unit 183 to adjust the distance between the upper pressure roller 181 and the lower pressure roller 182 . is a component that That is, the roller spacing adjusting unit 185 is to adjust the spacing between the lower pressure rollers 182 by moving the upper pressure roller 181 finely in the vertical direction.

The distance between the upper and lower pressure rollers 181 and 182 is kept smaller than the thickness of the carbon fiber fabric, so that the carbon fiber fabric passing between the upper and lower pressure rollers 181 and 182 is pressed. At this time, the roller spacing adjusting unit 185 detects the thickness of the carbon fiber fabric, which is slightly fluctuating, and adjusts the distance between the upper and lower pressure rollers 181 and 182 at a preset interval to make the carbon fiber fabric stronger. make it pressurized.
