Description

FRP double core manufacturing equipment 134

The present invention relates to an FRP double core manufacturing apparatus for manufacturing an FRP core, and more particularly, by adding a reinforcing band to an existing FRP core to manufacture a high-strength core.

In general, the winding core is made of glass fiber-reinforced plastic or epoxy resin, which has higher rigidity than other materials. It is used to wind up aluminum foil.

For example, an optical film used for a general LCD (Liquid Crystal Display) or PDP (Plasma Display Panel) is manufactured in a flat shape, and is transported and stored in a roll form through a winding process in transport and storage. .

Therefore, a transport core for winding and transporting the optical film is provided, and the optical film is designed according to its type and winding conditions, where the winding conditions are the type of film, the winding weight (usually about 08 tons to 2 tons). , winding tension, thickness, and modulus of elasticity, etc. In accordance with these conditions, the core has the strength and durability to sufficiently support the optical film in the form of a roll without deformation or damage even when the film is wound and the film roll is transported and stored. A material with is selected and designed.

A high-strength glass fiber reinforced plastic (FRP) may be used as a material for a core for transport and storage to meet these requirements.

The FRP (glass fiber reinforced plastic) is a material that combines aromatic nylon fibers such as glass fiber, carbon fiber, and Kevlar with thermosetting resins such as unsaturated polyester and epoxy resin. advantage.

Based on these characteristics, a FRP core is usually used to transport a high-precision and high-weight optical film and a copper foil or aluminum foil used in secondary batteries.

However, the thickness and diameter of the FRP core are selected according to the winding conditions of the optical film to be wound. In order to transport and store the FRP core by winding more optical films without deformation and damage through one FRP core, a small diameter As a result of the loss of the optical film due to curling and wrinkling of the film, the thickness and diameter inevitably increase, and the weight of the FRP core itself increases accordingly.

Although the FRP core is being transported by an operator, it is difficult for one operator to move the FRP core having a significant weight according to the above-mentioned problems.

Accordingly, there is a demand to minimize the weight of the core for transport.

To solve this problem, in order to maintain sufficient strength and durability and reduce weight, the conventional FRP core inserts two relatively small diameter FRP cores into the inner diameters of both sides of one large diameter FRP core and joins them in the central region It was designed to form an empty space in the space and to reduce the weight of the FRP core.

However, according to the above method, it is necessary to manufacture FRP cores having different diameters, as well as adding a bonding process between the FRP cores, which increases the cost and complicates the process. There was an additional necessary problem.

In addition, most of the conventional winding cores are manufactured in a cylindrical shape for weight reduction. However, if the winding core is required to have a long length depending on the type of optical film to be wound, bending occurs due to the load due to the weight of the optical film being wound. bar,

This not only shortens the life of the winding core, but also has a problem in that the optical film may be damaged in the process of winding or unwinding the optical film.

The present invention is to solve the problems of the prior art, and to facilitate the manufacture of the core by reinforcing the reinforcing strip during the manufacture of the FRP core, to achieve the weight reduction of the core, and to prevent the bending of the core by manufacturing the high-strength core It relates to an FRP double core manufacturing apparatus.

In addition, a comb-shaped pin member 134 and a guide rod 136 are coupled between the support plate 132 .

Preferably, the pin member 134 has a bar shape in which a plurality of pins protrude upward, and is fixed between one end and the other end of the support plate 132 .

In addition, the hopper 138 is coupled to the lower part of the guide part of the molding chamber to collect the excessively injected resin and to be re-injected into the loading box 122 .

As shown in FIG. 5, the forming chamber supply unit coupled as described above is fixed to a known rotating means (not shown) and rotates by combining several strands of forming chamber 20 on a long forming rod 10 that rotates. It forms a width and is guided by a pin member and a guide rod in a state of being deposited in the resin loaded in the loading box 122 and supplied to the molding rod 10 .

At this time, the resin that is excessively supplied by the precipitation of the molding chamber 20 is filtered by the pin member 134 and the guide rod 136 and re-injected into the loading box 122 through the hopper 138 .

And, the supplied molding chamber 20 is wound around the molding rod 10 by rotation of the molding rod (10).

Of course, since the molding chamber 20 is supplied in a state deposited in the resin, the liquid resin is supplied in a state wetted in the molding chamber 20 and wound up.

And, as shown in FIGS. 6 and 7 , the forming chamber supply unit 120 moves in one direction and the forming rod 10 rotates at the same time so that the forming chamber 20 constantly rotates the forming rod 10 . Thus, the forming chamber 20 is wound around the forming rod 10 .

In addition, the forming chamber 20 is wound at an inclination of 60° to 80° from the center of the forming rod 10 to form the inner diameter of the core 12 .

As shown in FIG. 8, the forming chamber supply unit 120 is transferred to the upper portion of the forming chamber 20 that is wound to form an inclination in one direction for the core 12 formed to form the inner diameter of the core 12 as described above.

The vertical direction 42 is inclined at 60° to 80°, and the transverse direction 44 is formed by winding at 0°.

This is because the reinforcing strip 40 is supplied in a grid shape alternately in the horizontal direction 42 and the vertical direction 44 of the reinforcing strip 40 , so that the forming chamber 20 is more easily and firmly reinforced and formed by the forming chamber 20 . This will be further reinforced.

In addition, since the transverse direction of the reinforcing band 40 is wound at 0° and reinforced in the axial direction of the core, it is possible to easily achieve reinforcing against bending.

All in all, the reinforcing band 40 may be used as a molding thread and a cotton thread or a molding thread or a cotton thread alternately, for example, the horizontal direction 44 may be used as the molding thread and the vertical direction may be used as the cotton thread 42, which It can be easily changed by the user's selection.

In addition, the reinforcing band 40 is preferably supplied without precipitation of the resin, but may be supplied in a state of being precipitated on the resin 40 by the user's selection.

Preferably, the reinforcing band 40 is supplied in part or continuously according to the user's need when the reinforcing band 40 forms the supply core from the initial stage of forming the core 12 by the user's selection, or when the core is formed. Core reinforcement can be achieved.

In addition, the reinforcing band may be supplied in several directions by the user's selection.

As shown in FIG. 12 , in the resin compression unit 160 , the compression rod 164 rotates around a hinge to compress or detach the core as needed when the core 12 is molded.

Therefore, in the manufacturing apparatus of the present invention, the vertical direction of the lattice-shaped reinforcing band is 0°, and is wound and formed in a straight line in the same manner as in the axial direction of the forming rod to achieve high strength to prevent bending of the core.

In addition, when the reinforcing band is supplied and wound, the forming chamber is also supplied at the same time, so that the core forming thickness is double supplied and wound, so that the forming of the core is made faster and easier.
