Description

Continuous fiber reinforced thermoplastic composite manufacturing equipment {APPARATUS OF MANUFACTURING CONTINUOUS FIBER REINFORCED THERMOPLASTIC COMPOSITE}

The present invention relates to a continuous fiber-reinforced thermoplastic composite manufacturing apparatus.

Continuous fiber-reinforced composites have recently been in the spotlight as industrial materials in relation to automobile, aviation, electronics, construction, sports, leisure, and defense industries, and have the advantage of being able to change their composition relatively freely in the molding process.

Continuous fiber-reinforced thermoplastic composites are continuously produced through a process of impregnating a thermoplastic resin in continuously supplied fibers and curing or solidifying them.

Meanwhile, among continuous fiber-reinforced composites, one-way prepreg (Unidirectional Sheet, hereinafter referred to as'UD sheet') impregnates a thermoplastic resin with glass fiber (hereinafter, referred to as'fiber' or'GF') in one direction. It is manufactured continuously by making. UD sheet has excellent mechanical properties and is used as a reinforcing material in areas with low physical properties of injection-molded products.

1 is a view schematically showing a fiber supply part of a conventional continuous fiber-reinforced thermoplastic composite manufacturing apparatus, and FIG. 2 is a view showing a conventional tension regulator.

The conventional fiber supply unit 10 is configured to be unwinded after each fiber bobbin 20 is connected to the krill. In particular, it consisted of a structure in which the fiber bobbin 20, which is traverse wound in the creel, is wound. And the fiber bobbin (GF bobbin) was configured such that the tension is adjusted by a tension regulator 30 including a spring 31 and a leather strap 33 (see Fig. 2).

However, according to such a conventional continuous fiber-reinforced thermoplastic composite manufacturing apparatus, there are the following problems.

First, there is a disadvantage that the fiber (GF) cannot be replaced during the operation of the composite material manufacturing apparatus. As a result, there is a problem in that the replacement time of the fiber (GF) is increased, resulting in a loss in the working time. For example, 30 to 300 GF may be wound on the krill depending on the width of the UD sheet. Therefore, when the fiber is exhausted, it is necessary to stop the manufacturing line and rewind the fiber, and a time is required to connect the rewound fiber with the existing fiber, which may take approximately 6 hours or more.

In addition, there may be a weight variation for each fiber bobbin, and due to this, there is a problem that the remaining fibers are lost as a loss. For example, if even one fiber in the krill was exhausted, the manufacturing process had to be stopped, and the remaining fibers had to be lost as loss. For this reason, there is a problem of an increase in loss due to continuous fiber exchange.

Next, there was a problem related to the fiber bobbin traverse winding. 3 shows an example of a conventional fiber bobbin. The conventional fiber bobbin 20 has a problem in that the distance difference between the center portion 21 and the side portion 23 is large, and a relatively large tension deviation occurs due to surface friction of the fibers GF.

Next, it was difficult to apply different fibers according to size and type. For example, fibers may have different inner diameter sizes for each type. In this case, it was necessary to use a dedicated krill suitable for the inner diameter of each fiber, and for this reason, there was inconvenience in that a device such as a separate adapter must be additionally configured.

As a prior document related to the present invention, there is Korean Patent Publication No. 10-2016-0054661 (published on May 17, 2016), and the prior document discloses an apparatus and method for manufacturing a one-way continuous fiber-reinforced thermoplastic composite.

It is an object of the present invention to provide a continuous fiber-reinforced thermoplastic composite manufacturing apparatus capable of reducing additional time loss due to fiber replacement by replacing fibers during operation of a continuous fiber-reinforced composite manufacturing apparatus, and minimizing residual fiber loss. .

To provide a manufacturing device.
