[0037] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Combine the following Figures 1 to 3 A particle coloring device according to an embodiment of the present invention is described, comprising a frame 1, a turntable 2, a drive assembly 3, a sliding rod 4, a spray gun 5 and a glaze slurry barrel 6;

[0040] The turntable 2 is rotatably arranged on one side of the frame 1, and the turntable 2 is tilted, and the tilt angle between the turntable 2 and the horizontal plane is set to 50° to 60°;

[0041] The driving assembly 3 is connected to one side of the turntable 2, and the other side of the turntable 2 is recessed inwardly to form a rolling cavity 20;

[0042] Driven by the driving assembly 3, the turntable 2 rotates around its axis.

[0043] The sliding rod 4 can be slidably disposed on the other side of the frame 1, and the sliding rod 4 can slide in a direction close to or away from the turntable 2;

[0044] The spray gun 5 is detachably arranged at one end of the sliding rod 4 , and the spray gun 5 is connected to the glaze slurry barrel 6 .

[0045] Specifically, in the specific operation of this embodiment, the prepared green particles are placed in the rolling cavity 20 of the turntable 2, and then the driving component 3 is started to drive the turntable 2 to rotate. Specifically, the angle of the turntable 2 is controlled between 50° and 60°, so that during the rotation of the turntable 2, the green particles located at the lower end of the turntable 2 are driven in the rotation direction. When the green particles are rotated to a certain height, the green particles located on the surface will first fall down to the lower end of the turntable 2 due to the action of gravity. Then, as the turntable 2 rotates, the green particles fall layer by layer, and the cycle repeats over and over again, thereby realizing the rolling of the green particles, so that the colored glaze can be sprayed on each green particle more evenly.

[0046] The distance between the spray gun 5 and the turntable 2 is adjusted by adjusting the movement of the sliding rod 4, and then the spray gun 5 is turned on. The spray gun 5 draws the color glaze from the glaze barrel and then sprays it toward the blank particles in the turntable 2. The rotation of the turntable 2 drives the blank particles in the rolling cavity 20 to roll, so that the color glaze can be sprayed on each blank particle more evenly, ensuring that each blank particle is covered with the color glaze. By controlling the speed and time of the spray gun 5, the color glaze will not completely cover the blank particles. Figure 4 As shown, the coverage rate of each green body particle is different. In this way, when the green body particles are used to prepare ceramic tiles, due to the different coverage rates of the green body particles and the random orientation of each green body particle, the imitation stone texture formed on the surface of the ceramic tile will be more natural, the imitation stone pattern effect will be better, and the appearance decorative effect will be better; the overall structure is compact, the cost is low, and the color glaze is fully automatically sprayed, which not only effectively improves work efficiency and reduces labor costs, but also can improve the appearance decorative effect of the imitation stone ceramic tiles prepared from the green body particles.

[0047] In this preferred embodiment, a leak-proof plate 21 is provided at the edge of the rolling cavity 20. Specifically, the blank particles are arranged in the rolling cavity 20. In this embodiment, the leak-proof plate 21 is arranged around the edge of the rolling cavity 20. The leak-proof plate 21 is arranged to protrude inward from the edge of the rolling cavity 20, which can block the blank particles and effectively prevent the blank particles from falling out of the rolling cavity 20.

[0048] In this preferred embodiment, the frame 1 is provided with a bearing seat 22, and the bearing seat 22 is provided with a transmission shaft 23; one end of the transmission shaft 23 is connected to the turntable 2, and the other end is transmission-connected to the driving assembly 3.

[0049] Specifically, in the present embodiment, the volume of the turntable 2 is relatively large, and one end of the rotating shaft 51 is fixedly connected to the axial position of the turntable 2. A disc can be arranged at the end of the rotating shaft, and the disc is fixed to the bottom surface of the turntable 2 by screws. The turntable 2 is fixed to the frame 1 by the bearing seat 22, which is beneficial to improve the installation stability of the turntable 2, and at the same time improves the smoothness of the rotation movement of the turntable 2 and prevents jamming and the like.

[0050] In this preferred embodiment, a slanted crossbeam 11 is provided on one side of the frame 1, and the inclination direction of the slanted crossbeam 11 is perpendicular to the inclination direction of the turntable 2; an avoidance chamfer 12 is provided at one end of the slanted crossbeam 11, and the chamfer angle of the avoidance chamfer 12 is consistent with the inclination angle of the turntable 2.

[0051] Specifically, in order to realize the tilting setting of the turntable 2, the inclined crossbeam 11 is set on one side of the frame 1, and the frame 1 is installed on the surface of the inclined crossbeam 11 through the bearing seat 22. The surface of the inclined crossbeam 11 and the bottom surface of the turntable 2 are perpendicular to each other, and the driving component 3 is installed on the surface of the inclined crossbeam 11, so that the power of the driving component 3 is transmitted to the turntable 2 in a straight line, thereby improving the transmission efficiency and making the transmission more stable; in addition, the avoidance chamfer 12 is to avoid the turntable 2 to prevent the turntable 2 from colliding with the frame 1 during rotation, effectively protecting the frame 1 and the turntable 2, and improving the safety of the structure.

[0052] In this preferred embodiment, a glaze spraying fixing column 13 is provided on one side of the frame 1, a sliding hole 130 is provided at the top of the glaze spraying fixing column 13, the sliding rod 4 is limitedly disposed in the sliding hole 130, and the sliding rod 4 is slidably connected to the sliding hole 130;

[0053] The glaze spray fixing column 13 is provided with a locking screw 14, which is threadedly connected to the glaze spray fixing column 13 and communicated with the sliding hole 130. The locking screw 14 can be inserted into or removed from the sliding hole 130, thereby locking or loosening the sliding rod 4.

[0054] Specifically, the sliding rod 4 is limited in the sliding hole 130 for sliding movement, which can guide and limit the sliding movement of the sliding rod 4, prevent the sliding rod 4 from deviating during movement, ensure the stability and smoothness of the movement of the sliding rod 4, and adjust the distance between the spray gun 5 and the turntable 2 by sliding the sliding rod 4 in the sliding hole 130; when the sliding rod 4 determines the position, the locking screw 14 is inserted into the sliding hole 130 by twisting the locking screw 14, and the bottom end of the locking screw 14 is against the side of the sliding rod 4, and the sliding rod 4 is pressed against the inner wall of the sliding hole 130, so that the sliding rod 4 is clamped and fixed by the locking screw and the inner wall of the sliding hole 130, and the sliding movement of the sliding rod 4 is locked, so as to maintain the distance between the spray gun 5 and the turntable 2. When the distance between the spray gun 5 and the turntable 2 needs to be adjusted, the locking screw 14 is twisted to pull the locking screw 14 out of the sliding hole 130, so that the sliding rod 4 is loosened, and the sliding rod 4 can be moved for adjustment, which is simple and convenient to operate.

[0055] In this preferred embodiment, a rotation groove 40 is provided at one end of the sliding rod 4, the spray gun 5 is arranged in the rotation groove 40, and rotation shafts 51 are fixedly provided on both sides of the spray gun 5, and the rotation shafts 51 on both sides are respectively rotatably connected to the inner wall of the rotation groove 40;

[0056] The rotating shaft 51 on one side is provided with a steering nut 511 , and the rotating shaft 51 on the other side is provided with a threaded section, and the threaded section is connected with a locking nut 512 . The steering nut 511 and the locking nut 512 are both provided on the outside of the sliding rod 4 .

[0057] Specifically, the spray gun 5 is provided with a rotating groove 40 that can rotate, so as to adjust the angle of the spray gun 5 spraying the colored glaze material on the turntable 2, so as to avoid that the spray gun 5 cannot accurately spray on the blank particles after adjusting the distance between the spray gun 5 and the turntable 2. The spraying angle of the spray gun 5 can be adjusted by rotating the rotating shaft 51, and the operation is simple and convenient. When the direction of the spray gun 5 needs to be adjusted, it is adjusted by screwing the steering nut 511. When the direction of the spray gun 5 is adjusted, the locking nut 512 is screwed so that the locking nut 512 and the steering nut 511 clamp the two outer sides of the sliding rod 4, thereby locking the rotational movement of the rotating shaft 51, thereby locking the spraying angle of the spray gun 5. When the angle of the spray gun 5 needs to be readjusted, the locking nut 512 is screwed in the opposite direction to loosen the rotational movement of the spray gun 5, thereby adjusting the angle, and the operation is simple and convenient.

[0058] Combination Figure 3 , Figure 4 The method for preparing the stone-like patterned ceramic tile proposed by the present invention is described, which is applied to the particle coloring device as described above, and comprises the following steps:

[0059] Preparing a plurality of base material particles, combining the base materials according to a ratio, and pressing the combined base material particles;

[0060] The pressed base material particles are crushed, sieved and then spherical granulated to obtain blank particles;

[0061] Put the spherical blank particles into the turntable 2 of the particle coloring device, start the driving component 3, and drive the turntable 2 to rotate;

[0062] After adjusting the distance between the spray gun 5 and the turntable 2, the spray gun 5 is started, and the spray gun 5 draws glaze from the glaze slurry barrel 6 and sprays it on the surface of the blank particles, forming an irregular colored glaze coating layer on the surface of the blank particles;

[0063] The green material particles are used to make ceramic tiles, which are dried, sintered and polished to form decorative patterns imitating the appearance of stone on the surface of the resulting ceramic tiles.

[0064] Specifically, the green material particles are the main components of ceramic tiles. When the surface of the green material particles is covered with a stone-like colored glaze, the prepared ceramic tiles will have an imitation stone appearance and decorative effect. However, the current technology is to completely cover the green material particles with colored glaze, resulting in the color glaze coverage rate of each green material particle basically reaching 100%. The color distribution of the imitation stone prepared in this way is too uniform, the imitation stone effect is unnatural, and the appearance effect is poor. The present application sprays the green material particles with colored glaze through a particle coloring device, so that the coverage rate of the colored glaze coating layer wrapped on the surface of each green material particle is different. When preparing ceramic tiles with green material particles with uneven coverage, the imitation stone texture formed on the surface of the ceramic tile will be more natural, the imitation stone pattern effect will be better, and the appearance decorative effect will be better due to the different coverage rates of the green material particles and the random orientation of each green material particle.

[0065] Furthermore, in the step of spraying the glaze, the coverage of the green material particles by the glaze is controlled by controlling the distance of the spray gun 5, the time of the spray gun 5, the speed of the spray gun 5, the shape of the spray head and the rotation speed of the turntable 2;

[0066] The distance between the spray gun 5 and the turntable 2 is controlled between 20cm and 30cm; the time of spraying the spray gun 5 is controlled between 5min and 10min; the rate of the spray gun 5 is controlled between 50mL / min and 200mL / min; the shape of the nozzle adopts a straight line, fan shape or point spray type; the speed of the turntable 2 is controlled between 30r / min and 50r / min.

[0067] Specifically, the distance between the spray gun 5 and the turntable 2 is controlled by the movement of the sliding rod 4, and the distance between the spray gun 5 and the turntable 2 is controlled between 20 cm and 30 cm to avoid the color glaze completely covering the blank particles due to the distance being too close, resulting in a poor appearance of the imitation stone material, and to avoid the color glaze being unable to accurately fall on the blank particles in the turntable 2 due to the distance being too far;

[0068] The time of the spray gun 5 is controlled by the control switch of the spray gun 5 itself, and the time is controlled within 5 minutes to 10 minutes to avoid too short a time resulting in too low coverage of the color glaze on the blank particles, and too long a time resulting in the color glaze completely covering the blank particles and causing a poor appearance of the imitation stone;

[0069] The speed of the spray gun 5 is controlled by an oil pump, and the speed of the spray gun 5 is controlled between 50mL / min and 200mL / min to avoid the speed being too slow or too fast, resulting in too high or too low coverage of the color glaze material on the blank particles, which affects the appearance of the imitation stone material;

[0070] The covering effect of the glaze on the green material particles can also be changed by changing the shape of the nozzle. The speed of the turntable 2 is controlled by the driving component 3, and the speed of the turntable 2 is controlled between 30r / min and 50r / min to avoid the speed being too slow or too fast, resulting in the coverage rate of the green material particles being too high or too low, which affects the appearance of the imitation stone.
