FIG. 4 is a view showing a configuration of an apparatus for induction-heating a metal ink-coated steel sheet according to another embodiment of the present invention.

1 to 4, the present invention mainly relates to an inkjet apparatus including an inkjet 200, a nozzle 110, a head 120, a conveying means 130, a heater 140, a power source 150, a controller 160, The inkjet 200 includes a nozzle 110, a head 120, and a spindle motor 180. The inkjet head 200 includes a nozzle 110, a head 120, and a spindle motor 180. The heater 140 includes an induction coil 142 and a power supply 144.

The head 120 includes a cartridge for receiving metal ink, and controls the opening and closing of the nozzle 110 under the control of the controller 160. In FIG. 1, it is assumed that ten heads 120 are formed and metal ink of metal A and metal ink of metal B are accommodated in each head 120 at a ratio of 3: 7. For example, when the metal ink of the A metal, the metal ink of the B metal, and the metal ink of the C metal are accommodated in the respective heads 120 at a ratio of 3: 3: 4 respectively, opening and closing of each nozzle is controlled, . Alternatively, the nozzles 110 corresponding to the metal inks of the B metal are opened, and the two nozzles 110 corresponding to the metal ink of the A metal are opened, and one of the nozzles 110 corresponding to the metal ink of the C metal , The A metal and the C metal are applied at a ratio of 1: 2. That is, the metal to be alloyed can be controlled by adjusting the type of the metal ink accommodated in the head 120, and the ratio can be adjusted by adjusting the opening and closing of the nozzle 110 for spraying the metal link.

The nozzle 110 is formed at the lower portion of the head 120 and ejects the metal ink contained in the head 120. That is, the head 120 constitutes a plurality of heads, and each of the plurality of heads 120 can receive metal ink of one or more different components. Metal ink is sprayed onto the steel plate 100 through the nozzle 110 and sintered to coat the alloy.

The spindle motor 180 disposed on the upper portion of the rotating portion 132 rotates the rotating portion 132 and rotates the rotating portion 132. The rotating portion 132 rotatably supports the head 120, The fixed head 120 and the nozzle 110 are rotated to uniformly spray the metal ink on the steel plate 100. On the other hand, metal inks are constituted by uniformly distributing fine metal molecules of several nanometers to several tens of nanometers to a flux (water, oil, solvent, etc.), and different fluxes can be used depending on the kind of metal.

The power supply unit 150 may be a DC power supply. The power supply unit 150 supplies power to the inkjet 200, the heater 140 cooler 170, and the conveyance unit 130 as a power source.

The linear motor 190 is configured on the spindle motor 180 and is configured to advance the head 120 and the nozzle 110 in the longitudinal direction of the steel plate 10. [ The linear motor 190 can generate the thrust force in the longitudinal direction of the steel plate 10 in a state where the spindle motor 180 is fixed to the lower portion,

The transfer means 130 may be formed of any one of refractory glass, refractory plastic, and metal having magnetism, and preferably is made of a metal having magnetism in consideration of abrasion resistance. On the other hand, when the conveying means 130 is made of refractory glass, refractory plastic or metal having magnetic properties, heat is not generated by the induction type heater 140 described later. That is, although heat is generated in the steel plate 100 by the eddy current flowing in the steel plate 100, the conveying unit 130 is made of a material that does not generate eddy current, so no heat is generated. Since no heat is generated in the conveying means 130, the safety of the operator can be secured.

The conveying means 130 sinters the metal ink sprayed on the steel plate 100 by the heater 140 as described above and then transfers the heated steel plate 100 to the cooler 170 for blowing the cold air . The cooler 170 transfers the steel plate 100 to cool the steel plate 100 by blowing cool air. The conveying means 130 may be realized by a motor for driving the conveyor belt and the conveyor belt.

The heater 140 may be disposed on the upper side of the steel plate 100 conveyed by the conveying means 150. Or on the lower part of the steel plate 100. As described above, the heater 140 is controlled by the controller 160 to control the voltage, and accordingly, the temperature generated in the steel plate 100 can be controlled by the heater 140.

As described above, the heater 140 is composed of an induction coil 142 and a power supply unit 144 for supplying alternating current to the induction coil 142.

The heater 140 is controlled by the controller 160 and indirectly heats the steel plate 100 under the control of the controller 160. That is, when alternating current is supplied to the heater 140 and a vortex is generated in the steel plate 100 by the AC, heat is generated in the steel plate 100 due to the resistance caused by vortex in the steel plate 100, The metal ink applied to the steel plate 100 is sintered.

3, the heater 140 is formed on the left side and the ink jet 200 is formed on the right side. When the ink jet 200 is first advanced in the A direction (rightward to leftward), inkjet printing is performed on the steel plate 100, Dry. Unlike hot air drying in which the metal ink is dried from the outer surface, the steel plate 100 is heated using the heater 140 to perform local heating so that precise and delicate drying is possible than hot air drying. Further, since the drying is performed from the inside of the metal ink, the adhesion between the metal ink and the steel sheet 100 is superior to that of the hot air drying.

In a different embodiment, when proceeding in the B direction (direction from left to right), the steel sheet 100 is heated by induction, followed by coating with metal ink. The surface energy of the steel sheet heated by the induction heating increases so that the adhesion force between the metal ink and the steel sheet 100 increases. Accordingly, when the metal ink is coated on the steel sheet 100 heated by induction heating, the steel sheet 100 is gradually dried and cooled by the residual heat, thereby forming an excellent coating layer.

In Fig. 4, two heaters 140 are constituted and an ink jet 200 is formed therebetween to induction-heat the steel sheet 100, to coat the metal ink, and then induction-heat it again. When coating is performed in this manner, the adhesion between the steel sheet 100 and the metal ink increases, and an excellent coating layer can be formed. Further, since the steel sheet 100 is heated by local heating, precise and delicate drying is possible than hot air drying. Further, since the drying is performed from the inside of the metal ink, the adhesion between the metal ink and the steel sheet 100 is superior to that of the hot air drying.

3 and 4, the cooler 170 may be additionally provided, although the cooler 170 is not shown for convenience of explanation.

5 is a flowchart illustrating a process of induction heating and drying a metal ink-coated steel sheet according to an embodiment of the present invention.

Referring to FIG. 5, in step S202, the control unit 160 ejects metal ink onto the steel plate 100 through the nozzle 110. FIG.

The control unit 160 controls the conveying unit 130 to convey the steel plate 100 to the heater 140 in order to sinter the steel plate 100 in step S204. The power supply part 144 of the heater 140 applies the alternating voltage to the induction coil 142 and the eddy current is generated in the steel plate 100 by the alternating current generated in the induction coil 142. In step S206, heat is generated in the steel strip 100 by the resistance against the eddy current, so that the metal ink sprayed on the steel strip 100 is sintered. The heating for sintering the alloy by the heater 140 is referred to as indirect heating or induction heating, and heat is generated by a vortex induced in the metal plate 100, .

The control unit 160 controls the conveying unit 130 to convey the steel plate 100 to the cooler 170 in step S208. When the steel plate 100 is disposed in the cooler 170 in step S210, the cooler 170 blows cool air to the steel plate 100 to cool the steel plate 100. [ In this case, unlike hot air drying in which the surface of the metal ink is dried, local heating is performed by heating the steel sheet 100, so that precise and delicate drying is possible than hot air drying. Further, since the drying is performed from the inside of the metal ink, the adhesion between the metal ink and the steel sheet 100 is improved as compared with the hot air drying.

6 is a flowchart illustrating a process of induction heating and drying a metal ink-coated steel sheet according to another embodiment of the present invention.

Referring to FIG. 6, in step S302, heat is generated in the steel plate 100 by the AC voltage applied to the induction coil 142 of the heater 140. [

In step S304, the control unit 160 controls the conveying unit 130 to convey the steel strip 100 to the inkjet 200. [

In step S306, the control unit 160 ejects metal ink onto the steel plate 100 through the nozzle 110. [

In step S308, the control unit 160 controls the conveying unit 130 to convey the steel plate 100 to the cooler 170. [

When the steel plate 100 is transported and disposed in the cooling chamber in step S310, the cooler 170 blows cool air to the steel plate 100 to cool the steel plate 100. In this case, when the metal ink is coated on the steel sheet 100 heated by the induction heating, drying and cooling are gradually performed by the heat remaining in the steel sheet 100, thereby forming an excellent coating layer.

7 is a flowchart showing a process of induction heating drying a metal ink-coated steel sheet according to another embodiment of the present invention. Referring to FIG. 7, first, the steel plate 100 is disposed on the first heater 140 by using the conveying means 130.

In step S402, heat is generated in the steel plate 100 by the AC voltage applied to the first heater 140. [

In step S404, the control unit 160 controls the conveying unit 130 to convey the steel plate 100 to the inkjet 200. [

In step S406, the control unit 160 ejects metal ink onto the steel plate 100 through the nozzle 110. [

The control unit 160 controls the conveying unit 130 to convey the steel plate 100 to the second heater 140 in order to sinter the steel plate 100 in step S408.

The control unit 160 causes the second heater 140 to generate an alternating voltage and the alternating current generated in the induction coil of the second heater 140 causes the eddy current to be generated in the steel plate 100. In step S410, heat is generated in the steel strip 100 due to the resistance to vortex so that the metal ink sprayed on the steel strip 100 is sintered.

When the steel plate 100 is transferred to the cooler 170 in step S412, the cooler 170 blows cool air to the steel plate 100 to cool the steel plate 100 (step S414). In this case, when the metal ink is coated on the steel sheet heated by the induction heating, the remaining heat is gradually cooled to form an excellent coating layer.

However, it is to be understood that the embodiments according to the concept of the present invention are not intended to be limited to specific modes of operation, but include all changes, equivalents and alternatives falling within the spirit and scope of the present invention.
