Description

Material distribution method of simulated ceramic tile with internal texture and ceramic tile

Technical Field

The invention relates to the technical field of architectural ceramics, in particular to a material distribution method of a simulated ceramic tile with internal textures and a ceramic tile.

Background

The surface of the natural stone imitating ceramic tile has the effect of natural stone, and the patterns can be changed variously. With the continuous development of social economy, the requirements of people on living quality and living environment are continuously improved, so that the decorative material with natural stone imitation, simplicity and nature is deeply loved by people.

When the existing natural stone imitation ceramic tile is prepared and used, grooving can be carried out according to needs, but due to the contrast between the color of a base blank and the color of surface texture, the fidelity of the natural stone imitation ceramic tile is influenced.

The main reason for the above problems is that the existing tile products adopt a layered distribution mode, i.e. a base material is distributed with a bottom material, then a surface glaze is distributed on the bottom material (reverse printing process is opposite to the reverse printing process), stripe materials are distributed on the surface glaze through a printing process to form stone-like textures, and the textures are limited on the surface layer of a green body, after the tile body is grooved, white stubbles of the tile at the notch are exposed, i.e. the bottom penetration phenomenon occurs, and only color can be supplemented again or remedied by other modes, which seriously affects the construction speed and the use effect.

For example, patent 201510183953.0 discloses a multi-station feeding printing ceramic device, which controls the opening and closing of a main material valve and a toner valve, so that the main material and the toner material form a mixture in a mold and are pressed into a green brick. Although the mode can achieve the effect of full-body textures, controllability of positions and sizes of the textures is poor, and a material mixing phenomenon occurs. Resulting in a greater discrepancy between the texture of the finished tile and the texture of the design.

The automatic control of the suction pipe 1 for sucking the blanks is realized by controlling the suction mechanism 13 through a digital control system, and comprises the control of the suction amount and the suction time.

The XY axis is arranged in parallel to the support table 9, and the driving direction of the suction pipe 1 by the suction driving member 11 and the driving direction of the discharge pipe 2 by the discharge driving member 21 are perpendicular to the XY axis and are driven in the Z axis direction.

The digital material distribution is completed by matching actions in three directions of XYZ axes, so that the texture controllability is strong and the texture reduction degree is high.

A digital material distribution method based on the digital material distribution system comprises the following steps (1) to (5).

(1) Texture information is preset in the digital control system. The texture information includes size information and/or color information of the texture. The process of presetting the texture information is to directly input the texture information into the digital control system through a human-computer interaction interface, or to input the texture photo into the digital control system through a scanner, and the digital control system identifies the texture photo to obtain the texture information.

(2) And placing the distributed basic backing material 10 at a preset position below the material sucking pipe 1 and the material discharging pipe 2, namely placing the blank 10 at a preset position of the bottom supporting platform 9. And the blank is transferred to the upper part of the supporting platform from the distributing machine in a conveying mode of a conveying belt.

(3) The material sucking pipe 1 and the material discharging pipe 2 move to the initial positions under the driving of the X-axis driving mechanism and the Y-axis driving mechanism. The initial position is set by the control system according to the texture information, and different textures are set to different initial positions.

(4) The material suction driving part 11 enables the material suction pipe 1 to move downwards to a preset distance, meanwhile, the inserting plate 12 is inserted into the blank 10, the air suction mechanism 13 generates negative pressure, and the material suction pipe 1 sucks the blank at the corresponding position on the blank 10; when the X-axis driving mechanism or the Y-axis driving mechanism drives the material suction pipe 1 to start to translate, the discharging driving piece 21 drives the discharging pipe 2 to move downwards to the position above a blank space formed by material suction, and meanwhile, the colored powder in the discharging pipe 2 falls into the blank space formed by the blank suction pipe 1 from a gap between the flashboard 5 and the inner wall of the bent part.

(5) The X-axis driving mechanism and the Y-axis driving mechanism continue to drive the material sucking pipe 1 and the material discharging pipe 2, and bottom layer textures are formed on the blank 10 according to preset texture information.

When the X-axis driving mechanism or the Y-axis driving mechanism drives the material sucking pipe 1 and the material discharging pipe 2 to move in a reversing way, the self-rotating mechanism 4 drives the material sucking pipe 1 and the material discharging pipe 2 to rotate, and the material discharging pipe 2 is kept to be located at the lower position of the movement of the material sucking pipe 1 all the time. The reversing movement of the material suction pipe 1 and the material discharge pipe 2 means that: the movement along the X-axis is converted into the movement along the Y-axis, the movement along the Y-axis is converted into the movement along the X-axis, and the like. When the material sucking pipe 1 and the material discharging pipe 2 are switched to move in different directions, the self-rotating mechanism 4 drives the material sucking pipe 1 and the material discharging pipe 2 to rotate, so that the material discharging pipe 2 is always positioned at the lower position where the material sucking pipe 1 moves, colored powder can accurately fall into a vacant position formed by the material sucking pipe, and texture transition can be smooth and natural.

The preset texture information comprises size information and/or color information of textures, and the digital control system adjusts the working quantity of the suction pipe 1 and the discharge pipe 2 and adjusts the displacement of the suction pipe 1 and the discharge pipe 2 according to the preset texture information. The width of the texture can be adjusted by adjusting the working number of the material suction pipe 1 and the material discharge pipe 2. Colored powder with various colors is placed in the plurality of discharging pipes 2, and the color of the texture can be controlled by adjusting the working amount of the discharging pipes 2.

For example, when the preset texture has a large width, a plurality of adjacent groups of the material sucking pipes 1 and the material discharging pipes 2 work simultaneously, and the adjacent material sucking pipes 1 suck materials simultaneously to form a wide vacant position, so that the wide texture is formed after the colored powder is filled.

For example, when the preset texture has a plurality of colors arranged on the same cross section, colored powder of the corresponding color is added in advance into the storage container corresponding to the discharge pipe 2. When the cloth is distributed, the discharge pipes 2 and the suction pipes 1 work simultaneously, and the texture with various colors arranged on the same cross section is formed.

For example, the preset texture is composed of a plurality of parallel strip textures, so that a plurality of groups of material sucking pipes 1 and material discharging pipes 2 which accord with the interval distance of the preset texture work, and when the strip textures are different in color, colored powder with corresponding colors are added into the material discharging pipes 2 at corresponding positions.

(6) And arranging a mark which can be identified by printing equipment on the green brick with the bottom texture, wherein the mark corresponds to the information of the bottom texture on the green brick. The mark is a mark which can be decomposed and eliminated by ink and the like after the ceramic tile is fired at high temperature, and the mark is a digital symbol mark, a bar code mark or a two-dimensional code mark.
