Abstract

Disclosed herein are an apparatus of manufacturing a panel for home appliance by performing uniform surface processing on the panel and a method of manufacturing a home appliance by performing uniform surface processing on a panel. The apparatus of manufacturing a panel for home appliance includes a contacting roller configured to perform surface-processing on a panel that is to be processed; a pressing roller configured to press the panel toward the contacting roller; and a supporting roller configured to support a center middle portion of the contacting roller.

First claim

What is claimed is:

1. An apparatus for manufacturing a panel for a home appliance, comprising:
two brackets;
a contacting roller connected to the brackets such that both ends of the contacting roller are supported rotatably in a vertical direction, the contacting roller configured to perform surface-processing on a panel that is to be processed;
a pressing roller configured to press the panel toward the contacting roller;
a supporting roller supported on the brackets above the contacting roller and configured to support a middle portion of the contacting roller;
a belt having a rough surface to form hair-line textures or scratch patterns on the panel and configured to be pressed against the panel by the contacting roller;
a tensioning roller provided above the supporting roller to maintain a tension of the belt;
a tensioning cylinder configured to maintain spacing between the contacting roller and the tensioning roller; and
a connecting rod provided between the brackets and connecting the tensioning cylinder to the brackets,
wherein the belt is tensioned by the contacting roller and the tensioning roller, and is extended while maintaining the tension.

2. The apparatus according to claim 1 , further comprising a plurality of supporting rollers arranged at regular intervals above the contacting roller.

3. The apparatus according to claim 1 , further comprising a receiving roller disposed between the contacting roller and the supporting roller.

4. The apparatus according to claim 3 , further comprising a plurality of receiving rollers.

5. The apparatus according to claim 3 , wherein a length of the receiving roller is longer than or equal to a length of the contacting roller.

6. The apparatus according to claim 1 , wherein the supporting roller has a length that is shorter than a length of the contacting roller, and is disposed at a center of the contacting roller.

7. The apparatus according to claim 1 , wherein the pressing roller is disposed below the contacting roller, and presses the panel upward.

8. The apparatus according to claim 1 , wherein the pressing roller presses the panel when the panel arrives at a position between the contacting roller and the pressing roller, and releases a pressure applied on the panel before the panel escapes from between the contacting roller and the pressing roller.

9. The apparatus according to claim 1 , further comprising a pinching apparatus disposed in front of or behind the contacting roller and the pressing roller, and configured to pinch the panel,
wherein the pinching apparatus comprises an upper pinching roller disposed above the panel, and a lower pinching roller disposed below the panel, and
wherein the pinching apparatus pinches the panel when the panel arrives at a position between the upper pinching roller and the lower pinching roller, and releases the pinching of the panel before the panel escapes from between the upper pinching roller and the lower pinching roller.

10. The apparatus according to claim 9 , wherein the pinching apparatus comprises a plurality of upper pinching rollers, and a plurality of lower pinching rollers corresponding to the plurality of upper pinching rollers.
