Abstract

The present application relates to a pattern forming method for quartz surface and a pattern forming device for quartz surface. According to the pattern forming method for quartz surface of the present application, by comprising a step of forming a pattern and a step of forming a color, it is possible to freely express the color on the pattern simultaneously along with forming the pattern on the quartz surface. And, in addition to these steps, by optionally comprising a step of additionally forming a pattern, it is possible to freely form a desired pattern on the quartz surface, and, by adding long line type patterns on the quartz surface unlike existing conventional quartz surfaces, it is possible to produce the quartz surface showing patterns and textures which are more natural and close to natural stone.

Claims (37)

1. A pattern forming device for quartz surface comprising:

a transfer part for transferring a semi-finished product of quartz surface;

a pattern forming part for forming a pattern on the semi-finished product of quartz surface conveyed by the transfer part;

an additional pattern forming part for further forming at least one pattern on the semi-finished product of quartz surface in which the pattern is formed in the pattern forming part; and

a color forming part for forming a color in the pattern of the semi-finished product of quartz surface formed in the pattern forming part,

wherein the pattern forming part, the additional pattern forming part and the color forming part are positioned with a serial structure in order on the transfer part,

wherein the pattern forming part comprises: a roller in which a disc shape or a spring shape with at least one curve is embossed; a motor for adjusting a speed of the roller; a first up-down adjustment unit for adjusting a height of the roller; and a first sensor for sensing a pattern formation position on a surface of the quartz surface.

2. The pattern forming device for quartz surface according to claim 1 , wherein the transfer part comprises a support;

a belt for conveying the semi-finished product of quartz surface; and

a first rotation drive unit for rotating the belt.

3. The pattern forming device for quartz surface according to claim 1 , wherein the additional pattern forming part comprises a first additional pattern forming part including a plate having at least one protrusion.

4. The pattern forming device for quartz surface according to claim 3 , wherein the first additional pattern forming part comprises: a plate having at least one protrusion;

a second up-down adjustment unit for adjusting a height of the plate having at least one protrusion; and

a second sensor for sensing a pattern forming position on the semi-finished product of quartz surface.

5. The pattern forming device for quartz surface according to claim 1 , wherein the additional pattern forming part comprises a second additional pattern forming part for pressing two or more plates, in which two or more slot shapes are embossed, in a caterpillar manner, to form a pattern.

6. The pattern forming device for quartz surface according to claim 5 , wherein the second additional pattern forming part comprises: a plate in which two or more slot shapes are embossed;

a connecting structure for connecting the plate in which two or more slot shapes are embossed to each other;
