The specific embodiment

In the drawings, represented one according to the system that is used for for the powder layout that forms Ceramic Tiles or ceramic wafer change formation band of the present invention.

This system comprises the vertical hopper 34 that is arranged in surperficial 2 tops, and surface 2 can the direction of arrow be moved in Fig. 1, is suitable for transmitting predetermined ceramic powders layer 200, abbreviates basic unit as.

Basic unit 200 realizes that by the ceramic powders of discharging from distributor 70 distributor 70 has the discharge port by wicket 71 sealings.Described powder discharging is on described horizontal movable surface 2 tops, and is and smooth rightly by the scraper 72 that is suitable for regulating basic unit's 200 thickness.

Funnel 34 has parallelepiped columnar structure, has first couple of surperficial 34c, is called the side, and the direction of advance that is parallel to movable surface 2 arranges and second couple of surperficial 34a that 34b is respectively front and rear surfaces, arranges perpendicular to the direction of advance of movable surface 2.Funnel 34 by suitable feed arrangement from the opening 37 of the top color powder 33 of packing into, for the ease of showing, feed arrangement is not expression in the drawings, color powder 33 is arranged in a predefined manner and the opening 38 below passing through under the gravity effect descends continuously, and opening 38 is arranged in apart from basic unit 200 (its by surface 2 transmit) and equals on the position of color powder band 100 thickness " S " that will deposit.

Preferably, funnel 34 has between front surface 34a and rear surface 34b and equals to be deposited on the enamel spacing " B " of powder belt 100 thickness " S " of basic unit 200.By this way, on this basic unit that advances continuously 200 surfaces, can form color powder layer 100, be replicated in the identical predetermined arrangement of color powder in the funnel 34 33.Especially, form the typical texture that is suitable for duplicating natural stone with 100 color powder 33.

According to the present invention, this system comprises the device that is used for forming groove 20 in the basic unit 200 of funnel 34 upstreams, and groove 20 will be filled up by the color powder 33 of discharging from funnel 34 in the process of advancing of basic unit 200.

Such groove 20 causes the predetermined arrangement that forms with 100 color powder 33 to change, and does not have the words of groove 20 will be replicated in the identical predetermined arrangement of powder in the funnel 34 33.
