Abstract

A decoration moethod for the ceramic product simulating natural stone features that the ceramic press, stone vein die and patterned paper are used for punching once to form said ceramic product. Its advantages are lifelike, fine and color surface vein, and high quality.

Description

A kind of trailing of ceramic product

One, technical field

The present invention relates to a kind of trailing of ceramic product, the particularly a kind of surperficial fine color of natural-like stone Art Stone ceramic product and the one time punching molded trailing of texture.

Two, technical background

1, according to the manufacturing procedure difference of ceramic product, ceramic product surface pattern, Spanish furnish can be divided into three kinds:

(1) a kind of is surface decorating method in the forming process: comprising (a) die pressing (method of embossing): promptly shaping mould tool surface has concavo-convex grain pattern, and the base substrate after the moulding has the trailing with the corresponding grain pattern of mould.This trailing only shows the fluctuating characteristics of product surface, and color and mechanism can't change.(b) dry powder print process: colored powder scatters on blank through setting in advance the film or the screen cloth of figure pit, and blank is pressed into the trailing of base substrate again.In this trailing, the toner freely falling body is to the blank face, and the figure line is not meticulous.

(2) a kind of be at the base substrate table and trailing comprising the printing of: (a) serigraphy (b) glue rod printing (c) decal paper

(3) a kind of is comprising (a) decal paper trailing (b) Freehandhand-drawing (c) die in the trailing on ceramic product surface

2, the requirement of fine color and grain pattern trailing

In the above-described trailing

(a) die pressing only forms embossment (concavo-convex) grain effect of product surface, does not solve color, figure line mechanism problem.

(b) dry powder print process: film or screen cloth and blank face have certain spacing, do not contact mutually, and the printing toner is freely fallen blank surface, and grain pattern is coarse, and stereovision is poor.

(c) serigraphy, the printing of glue rod and decal paper are decorated the decoration that is suitable for fine color and grain pattern.But require the surface of decorated body smooth substantially, concavo-convex fluctuating is little.For resembling the lithotome Art Stone, the concavo-convex variation on surface greatly, sharply, rectangular sometimes, said method is not suitable for, position, angle grain pattern can't be printed onto, grain pattern is discontinuous, causes broken string, lacks colored distortion.

3, the trailing of up-to-date release natural-like stone Art Stone ceramic product: the natural-like stone Art Stone, complied with the urbanite and returned Piao and return genuine psychological needs.American-European developed country, the natural-like stone Art Stone has become the main product of building ceramic tiles, and China comes into vogue in the big city.Italian POLO was taken (Bologana) international pottery and ceramic machinery exhibition in 2002, had put on display ceramic product and production equipment thereof with secondary pressing natural-like stone Art Stone.The secondary punching press is with two press series connection, and decorating apparatus such as dry powder printing, distributing device are installed between the press.Workflow is: first press low-pressure (40～80kg/m ²) the first base of molding flat, carrying out decorations such as dry powder printing on first base surface, first base moves into second press again, at high pressure (300kg/m ²) punch forming, finish bag and last moulding.Wherein the die surface of second press has the stone material Z-Correct bump mapping Z-correct.

Three, summary of the invention

The problem that the present invention mainly solves is;

How easier the fine color of finishing natural-like stone Art Stone surface (sharp-pointed concavo-convex contoured surface) and the decoration of grain pattern, figure line keep not breaking continuously.

Equipment and apparatus that the present invention adopts:

(1) die surface used of conventional ceramic press, press has imitating natural stone texture.

(2) marble paper and paper feeder.

Trailing of the present invention is to adopt a pressing to finish to decorate and moulding, the steps include:

(1) passes through grid or belt to press punching press position feeding;

(2) marble paper is delivered to press punching press position, the decorative pattern face of marble paper contacts with powder;

(3) be pressed into base substrate.

Against existing technologies, the present invention has following three beneficial effects

(1) operation is simple, saving equipment and fund.Adopt a pressing to finish and decorate and blank forming, save a press.Press is a most critical equipment in Production of Ceramics, accounts for important proportion in the investment.

(2) decorative effect is meticulousr.The printing of marble paper belongs to planographic, and with the serigraphy of contact, the printing of glue rod, than contactless dry powder printing, figure line, gradation are meticulousr.

(3) trailing of the present invention is simple, and press and marble paper are technique known, need not do big equipment and change, and highly versatile has remarkable economic efficiency.

Four, description of drawings:

The schematic diagram of the grid feeding type punching press shaping equipment system of Fig. 1, natural-like stone Art Stone.

The schematic diagram of the ribbon feeding formula punching press shaping equipment system of Fig. 2, natural-like stone Art Stone.

Among the figure: 1, grid; 2, hopper; 3, press; 4, upper punch; 5, marble paper; 6, ejection platform; 7, base substrate; 8, framed; 9, low punch; 10, die cavity; 11, grid mobile platform; 12, powder; 13, cyclical level belt; 14, send the marble paper device.

Five, specific embodiment method:

Embodiment 1 Fig. 1 is a natural-like stone Art Stone grid feeding type punching press shaping equipment system schematic.

This device systems, except that comprising known grid 1, hopper 2, press 3, upper punch 4, low punch 9, framed 8, die cavity 10, grid mobile platform 11, ejection platform 6, the asperities that natural-like stone is also arranged in upper punch 4 surface engravings especially, above ejection platform 6, be provided with one and send marble paper device 14 automatically, deliver marble paper from trend die cavity 10.Wherein the marble paper papery is the gas permeable material with certain resilient flexible, and repeatedly meticulous chromaticity diagram escutcheon brush has been carried out with ceramic pigment in its surface.The seal charge level of marble paper corresponding with the powder face (contacting).

Use that the said equipment system decorates and the method for moulding, its concrete steps comprise: grid 1 moves to press 3 directions along grid mobile platform 11.Hopper 2 is reinforced to grid 1, and grid 1 arrives low punch 9 tops, and low punch 9 moves down, and grid 1 is to framed 8 reinforced, and grid 1 returns, and charge level is wipeed off, takes back remaining powder simultaneously.Send marble paper device 14 that marble paper is delivered to powder surface in framed 8, the seal charge level contacts with powder.Upper punch 4 moves down, and powder is pressed into base substrate.Move on the low punch 9, grid 1 is fed to low punch 9 tops, simultaneously base substrate is pushed out to ejection platform 6.Finish the decoration and the moulding of natural-like stone Art Stone.Repressed firm being impressed on the blank of color on the marble paper and figure line material is again through burning till the Art Stone that (or throw off marble paper and burn till) promptly gets natural-like stone.Embodiment 2 Fig. 2 are natural-like stone Art Stone ribbon feeding formula punching press shaping equipment system schematic.

This device systems, remove and comprise known hopper 2, cyclical level belt 13, press 3, upper punch 4, low punch 9, also especially above the cyclical level belt 13, between press 3 and the hopper 2, marble paper device 14 is sent in installation, and upper punch 4 die surfaces are carved with the concavo-convex grain pattern of natural-like stone Art Stone.
