An outlet of each feeding space is provided with a discharge baffle 8, a drive member 9 is arranged corresponding to the discharge baffle 8 to drive the discharge baffle 8 to rise and fall, thereby controlling an open/close state and an opening size of an outlet of the feeding space.

[0192] One or more detection sensors 11 are arranged to correspondingly control one or more drive members 9 to operate. When a detection sensor 11 at a specified position detects a raw material, a corresponding drive member 9 is started to drive a corresponding discharge baffle 8 to close or open. In this example, 9 detection sensors are provided, including 1101.1, 1101.2, 1101.3, 1101.4, 1101.5, 1101.6, 1101.7, 1101.8, and 1101.9; the 9 detection sensors are arranged in a rectangular array, where the detection sensor 1101.1 correspondingly controls the falling of texture materials in storage cavities 4013.1, 4014.1, 4014.2, 4015.1, 4016.1, 4016.2, 4017.1, 4018.1, and 4018.2 to the feeding conveyor belt 6 below the storage cavities, and the detection sensor 1101.5 correspondingly controls storage cavities 4013.3, 4015.4, and 4017.5.

[0193] The angle β is set to 75°.

[0194] In step b, the storage cavities 4013.1 and 4013.3 each are filled with the dark-gray material, the storage cavities 4014.1 and 4014.2 each are filled with the mixture of the dark-gray and black materials, the storage cavities 4015.1 and 4015.4 each are filled with the light-gray material, the storage cavities 4016.1 and 4016.2 each are filled with the mixture of powdery, flaky, and granular materials obtained by inhomogeneously mixing and then pre-crushing the dark-gray, light-gray, and black materials, the storage cavities 4017.1 and 4017.5 each are filled with the mixture of the dark-gray and light-gray materials, the storage cavities 4018.1 and 4018.2 each are filled with the mixture of the light-gray and black materials, the storage cavity 4011.1 is filled with the white material, and the storage cavity 4012.1 is filled with the black material.

The distribution device is initiated, a roller motor of each feeding hopper of the texture powder feeding module 102 allows texture materials in storage cavities 4013.1, 4014.1, 4014.2, 4015.1, 4016.1, 4016.2, 4017.1, 4018.1, and 4018.2 correspondingly controlled by the detection sensor 1101.1 to fall onto the feeding conveyor belt 6 below the texture powder feeding module 102 according to preset running and pause times, and roller motors for storage cavities 4011.1 and 4012.1 of the line powder feeding module 101 allows line materials in the storage cavities 4011.1 and 4012.1 to fall onto the feeding conveyor belt 6 below the line powder feeding module 101 according to preset running and pause times, during which, due to the different preset running and pause times of the line powder feeding module 101 and the texture powder feeding module 102, the raw materials of different colors are not overlapped, partially overlapped, or semi-overlapped on the feeding conveyor belt.

[0196] The texture material on the feeding conveyor belt 6 below the texture powder feeding module 102 falls into the material-accommodating cavity 201 through the material-receiving hopper 7 at an opening of the upper end of the powder-preforming box 2, and the line material on the feeding conveyor belt 6 below the line powder feeding module 101 also falls into the material-accommodating cavity 201 through the material-receiving hopper 7 at the opening of the upper end of the powder-preforming box 2 during a predetermined pause interval of the feeding conveyor belt 6 below the texture powder feeding module 102.

The raw materials in the material-accommodating cavity relies on their own weights to flow. When the detection sensor 1101.1 no longer detects a material, corresponding storage cavities are opened once again for feeding, thereby circularly forming a raw material layout in the material-accommodating cavity.

[0197] The raw materials on the feeding conveyor belt 6 fall onto the accumulated materials in the material-accommodating cavity 201 through the material-receiving hopper 7. As shown in FIG. 17, the raw materials accumulate and flow in the material-accommodating cavity 201 at an accumulation angle from top to bottom, and the raw materials fallen into the material-accommodating cavity 201 form a slope-like fluid textured layout 19 in the material-accommodating cavity under the control of corresponding detection sensors, and then are stored in the powder-preforming box 2.

[0204] The angle β is set to 90°.

[0205] The texture material on the feeding conveyor belt 6 below the texture powder feeding module 102 falls into the material-accommodating cavity 201 through the material-receiving hopper 7 at an opening of the upper end of the powder-preforming box 2, and the line material on the feeding conveyor belt 6 below the line powder feeding module 101 also falls into the material-accommodating cavity 201 through the material-receiving hopper 7 during a predetermined pause interval of the feeding conveyor belt 6 below the texture powder feeding module 102. The raw materials accumulate in the material-accommodating cavity 201 with a corresponding feeding width until a set accumulation height is reached. When the detection sensor 1101.5 detects a material, feeding spaces under the corresponding storage cavities are closed; and when the detection sensors 1101.1 and 1101.3 do not detect a material, a material is further fed by corresponding storage cavities, then moves with the feeding conveyor belt 6 into the material-accommodating cavity 201 through the material-receiving hopper, and accumulates in the material-accommodating cavity 201 until the material can be detected by the detection sensors, and then the storage cavities are closed.

[0206] Refer to FIG. 19, the raw materials accumulate in the material-accommodating cavity at an accumulation angle from top to bottom to form a peak-like textured layout 24, and the raw materials of the peak-like textured layout are stored in the powder-preforming box 2.

[0209] Refer to FIG. 21. In this example, the pressing machine 14 is a stamping pressing machine with a mold cavity, and the secondary conveyor belt assembly 16 is a retractable movable conveyor belt in the prior art. A transition plate 17 is further provided at a discharge end of the secondary conveyor belt assembly 16. When the secondary conveyor belt assembly 16 moves forward to a mold cavity position of the pressing machine, the raw materials of the full-body fluid textured layout 19 or the raw materials of the peak-like textured layout 24 fall into the mold cavity of the pressing machine, and after the distribution, the secondary conveyor belt assembly 16 immediately retracts to a position below the belt conveying assembly 3 for the next round of material-receiving and distribution.

[0210] When the secondary conveyor belt assembly 16 leaves the mold cavity position of the pressing machine, the pressing machine starts stamping to form a green body, raw materials of a full-body fluid textured layout 19 received in the next round move forward with the secondary conveyor belt assembly 16, the green body previously pressed is pushed out of the pressing machine, and the next round of distribution is conducted, thereby forming a cycle of distribution, pressing, and conveying continuously prepared green bodies to the drying kiln for drying.

[0211] In this example, another manufacturing method of a full-body textured porcelain stoneware slab is disclosed, which is different from the above example in that:

[0212] Refer to FIG. 22. In this example, the pressing machine is a stamping pressing machine with a mold cavity, the secondary conveyor belt assembly 16 is further provided with a frame feeding grille 1601 which has an existing structure, such as a grille structure disclosed in Chinese Patent Application No. CN201010227330.6 or Chinese Patent Application No. CN200810088848.9.

[0213] In the pressing procedure, the frame feeding grille 1601 frames the raw materials on the conveying plane of the secondary conveyor belt assembly 16 and moves forward to a mold cavity position of the pressing machine, then the raw materials of the full-body fluid textured layout 19 or the raw materials of the peak-like textured layout 24 fall into the mold cavity of the pressing machine, and after completing the framing, the frame feeding grille 1601 immediately retracts to a position above the secondary conveyor belt assembly 16 for the next round of material-framing and distributing.

[0214] When the frame feeding grille 1601 leaves the mold cavity position of the pressing machine, the pressing machine starts stamping to form a green body, raw materials of a full-body fluid textured layout framed in the next round by the frame feeding grille 1601 move forward, the green body previously pressed is pushed out of the pressing machine, and the next round of distribution is conducted, thereby forming a cycle of distribution, pressing, and conveying continuously prepared green bodies to the drying kiln for drying.

Example 11

[0215] In this example, in the step b, the feeding hoppers of the feeding assembly 1 comprise pit carved roller feeding hoppers and flat roller feeding hoppers; or

[0216] in step b, the raw materials on the feeding conveyor belt 6 are deflected by the deflector rod 12 to adjust a layout of the raw materials on the feeding conveyor belt 6, or the raw materials are disturbed when falling into the material-accommodating cavity 201, such that a layout of the raw materials in the material-accommodating cavity 201 changes; or

[0217] in step c, in the material-accommodating cavity of the powder-preforming box 2, the barrier strip 2013 is adjusted to make a layout of the raw materials in the material-accommodating cavity 201 change; or

[0218] in step b, positions of the partitions 10 in the feeding hopper and/or one or more discharge baffles of the split-type discharge baffles 8 are adjusted to adjust feeding widths, feeding positions, and feeding amounts of the feeding portions 5 of the feeding hoppers and thus make the raw materials enter the material-accommodating cavity 201 to form different accumulation surfaces, such that accumulation and flow patterns of the raw materials in the material-accommodating cavity 201 change.

[0219] Thus, in continuous production, a full-body green body fluid textured porcelain slab that has basically consistent main bodies and slope-like texture changes shown in FIG. 23 of the present disclosure can be produced as required. In addition to a line zone 1801 and a texture zone 1802, the porcelain slab 18 includes a line change zone 1803 and a texture change zone 1804.

Therefore, the present disclosure is not limited to the specific embodiments disclosed and described above, and some modifications and changes made to the present disclosure should also fall within the protection scope of the claims of the present disclosure. In addition, although some specific terms are used in the specification, these terms are provided to merely illustrate rather than limit the present disclosure.
