The present invention relates to an induction heating coil, and more particularly to an induction heating coil assembly suitable for efficiently heating a target to be heated without winding the induction heating coil on the target.

Generally, in a high frequency induction heating system, when an induction heating coil is wound on a heating target and a high frequency current is applied to the induction heating coil side, a high frequency magnetic field is generated on the induction heating coil side, and eddy current (Eddy current) loss or hysteresis loss of the object to be heated.

Therefore, conventionally, in order to heat the heating target, a method of heating the heating target by winding an induction heating coil on the heating target itself has been mainly adopted.

However, conventionally, there is no technology for heating the heat generated in the induction heating coil by the heat transfer method by being radiated from the heating object.

Hitherto, there has been a technical limitation in a method of heating an object to be heated by using an induction heating coil.

On the other hand, industrial packaging or coated paper is coated with acrylic resin on paper (for example, paper), dried and then put into an overcoater to smooth and coat the coating layer with high heat and pressure.

The pushing roller 30 is usually made of a rubber material and is also called a rubber roller.

At this time, the coated paper is coated with acrylic resin on the paper (e.g., paper) and then dried, and the coated paper P is put into an overcoater to smooth the coated surface.

In the case of the conventional overcoating machine, the electric heater bar 50 is used as a heat source for heating the driving roller 10.

The electric heater bar 50 is built in the driving roller 10 and is usually controlled to a temperature of about 130 degrees to heat the driving roller 211. The chamber inside the stainless belt 213 is normally 90 It is maintained by the degree of the degree and plays a role of preheating.

However, when the electric heater bar is employed as a heat source for heating the driving roller in the prior art, there are the following problems.

First, the electric heater rod 50 has a problem of high power consumption, high production cost, and low energy efficiency.

Next, the electric heater bar is disadvantageous in that the temperature is irregular due to difficulty in precise and rapid temperature control.

Further, in the case of heating with the electric heater bar 50, there is a problem that the stainless belt 40 is stretched, discolored, and the service life is shortened.

As shown, the induction heating coil assembly 100 according to one embodiment of the present invention includes a rectangular substrate 130 for mounting the coil winding member 120, A coil winding member 120 (121,122) mounted on the coil winding member 120 and mounted on the driving roller 211 facing the heating chain driven by the coil winding member 120 and a high frequency current from the high frequency generating module A plurality of first mounting holes 131 formed in the substrate 130 and a plurality of second mounting holes 131 formed in the first mounting holes 131 to be inserted into the first mounting holes 131, The induction magnetic field generated in the induction heating coil 110 is formed only in a region where the heating target is present (for example, a region where the driving roller 211 to be heated is present) and a region opposite to the direction in which the heating target is present (In the direction opposite to the drive roller 211) And that comprises a shield member 140 for shielding property characterized.

In the induction heating coil assembly 100 according to one embodiment of the present invention, the substrate 130 is formed of a non-conductive and non-magnetic heat resistant resin material.

The substrate 130 is preferably embodied as Bakelite (TM), for example.

According to the above-described configuration of the shielding member 140, it is possible to shield the induction magnetic field primarily so as to prevent the induction magnetic force lines from being unnecessarily upward, thereby preventing the outer mounting frame 170 (e.g., the iron plate) from being heated There is an advantage to be able to.

The shielding member 140 may be made of, for example, ferrite.

In the induction heating coil assembly 100 according to an embodiment of the present invention, the substrate 130 is provided with a heat dissipation hole 132 for allowing heat to escape to the outside without staying inside. do.

This is because the plurality of heat dissipation holes 132 formed in the substrate 130 allow the heat of the induction heating coil to escape when the wind by the external fan blows.

The heat dissipation hole 132 may be formed alternately with the first mounting hole 131.

In the induction heating coil assembly 100 according to an embodiment of the present invention, the induction heating coil 110 is wound around the induction heating coil 110 in order to wind the induction heating coil 110 while keeping the induction heating coil 110 in a predetermined shape.

The reason why the spacers 150 are spaced apart is that the flow path of the cooling channel by the external fan can be well performed as the heat dissipating space and when the following shielding plate 160 adheres too much to the substrate 130, So that heat is generated in the shield plate 160 to prevent this.

The spacer 150 may be made of, for example, a long bolt.

Since the second shielding magnetic field of the induction heating coil is completely shielded by the shielding member 140, the mounting frame 170 can be prevented from being heated.

The shielding plate 160 is made of, for example, an aluminum plate.

In the induction heating coil assembly 100 according to one embodiment of the present invention, the induction heating coil assembly 100 is bent in the direction of the shield plate 160 and fastened to the shield plate 160, And further includes a mounting frame 170 for mounting the entire body to an external fixing device (main frame) (not shown).

The mounting frame 170 is made of, for example, an iron plate and has high strength and durability.

In the induction heating coil assembly 100 according to one embodiment of the present invention, the heating target is an overcoat, and the overcoater includes a driving roller 211, a stainless steel 220 wound around the driving roller 211, A driven roller 212 which is wound by the belt 213 and rotates depending on the rotation of the driving roller 211 and a driven roller 212 which is engaged with the driving roller 211 to rotate the coated material The induction heating coil assembly 100 is mounted on the driving roller 211 along the longitudinal direction of the driving roller 211. The induction heating coil assembly 100 is mounted on the driving roller 211, And is provided inside the belt 213 in the vicinity of the drive roller 211 in parallel.

According to this, the heat radiated from the induction heating coil assembly 100 is transferred to the driving roller 211 to be heated by the heat radiation method, so that it can be efficiently heated even if it is not wound around the driving roller 211 to be heated .

Further, since the induction heating coil assembly 100 is provided inside the belt 213, there is an advantage that the heating efficiency is further increased.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It is self-evident to those who have.

Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, so that the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
