The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

The invention is described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 to 11, a production line 100 for preparing sheet-like particles with linear textures according to an embodiment of the present invention includes a conveying device 10, a slurry spraying device 20, a feeding device 30, a scraping device 40, a drying device 50, and a slicing device 70.

Referring to fig. 1, a conveying device 10 is used for conveying a carrier 200; the slurry spraying device 20 is used for intermittently spraying slurry to the carrier 200 positioned below in the Z direction; the feeding device 30 is used for conveying the slurry with various colors to the slurry spraying device 20; the comb scraping device 40 is located at one side of the slurry spraying device 20 along the conveying direction of the conveying device 10, and is used for performing comb scraping on the slurry sprayed on the carrier 200 by the slurry spraying device 20 so as to enable the slurry to present linear textures; the drying device 50 is located at one side of the scraping device 40 along the conveying direction of the conveying device 10, and is used for drying the scraped slurry so as to enable the slurry in a flowing state to be dried into solid sheets; the cutting device 70 is used for breaking the sheet bodies on the carrier along the conveying direction of the conveying device 10 so as to obtain the sheet-like particles with linear textures.

In the above-mentioned production line 100 for preparing flaky particles with linear textures, the carrier 200 is conveyed by the conveyor 10, so that the carrier 200 can smoothly circulate in each step, the feeding device 30 is used for feeding multiple colors, so that the multiple colors of slurries can be continuously provided to the slurry spraying device 20, the slurry from the feeding device 30 is intermittently sprayed on the surface of the carrier 200 by the slurry spraying device 20, the slurry is gradually spread on the surface of the carrier 200 by virtue of the fluidity of the slurry, after the slurry spraying on the surface of the carrier 200 is finished, the slurry on the surface of the carrier 200 is combed by the combing and scraping device 40, so that the slurry can present linear textures as required, such as straight lines, curves, circular arcs and the like, after the combing and scraping of the slurry is finished, the slurry is dried by the drying device 50, so that the slurry in a flowing state is dried and changed into solid tablet bodies, finally the large flaky tablet bodies are cut and broken by the cutting device 70, and flaky particles with linear textures with smaller sizes can be finally obtained, and the flaky particles with various linear textures can be obtained by adopting flaky particles in the flowing state; specifically, the obtained flaky particles with fine linear textures can be applied to the subsequent manufacturing of tiles to prepare tiles with fine linear textures, and the flaky particles have a certain thickness, so that the tiles can have a certain stereoscopic impression when being formed.

The carrier 200 of this embodiment may be a substrate such as a pulp basin, a stainless steel plate, or a glass plate. When the carrier 200 is a substrate such as a stainless steel plate or a glass plate, the slurry layer after finishing showering can pass through the combing of the combing and scraping device 40, followed by drying by the drying device 50 and crushing by the dicing device 70 to enable the production of fine grain particles which can be used in the subsequent pressing and firing to produce finished tiles. The carrier 200 plays a role of receiving slurry droplets, and is used as a supporting platform for the subsequent combing and scraping device 40 to comb textures, and the mode of adopting matrixes such as a slurry receiving basin, a stainless steel plate or a glass plate is adopted, so that the carrier 200 has corrosion resistance, higher hardness and high temperature in the drying process of the drying device 50, and the carrier 200 can be ensured to maintain a better surface state after long-term use.

In this embodiment, the surface roughness Ra of the carrier 200 is between 0.05 μm and 0.20 μm, so that the surface roughness Ra of the carrier 200 is low, so that the sheet can be easily peeled off when the sheet is formed into a sheet after the subsequent slurry is dried, and if the surface roughness of the carrier 200 is high, the sheet formed by drying the slurry and the carrier 200 are combined too tightly, and are not easy to be taken off, resulting in undersize of the sheet particles obtained during the taking-off, and even resulting in destruction of the fine texture formed.

The conveying device 10 in this embodiment may be a conveying belt type conveying device, where the conveying belt has a sufficient supporting surface to stably support and convey the carrier 200.

Specifically, when the carrier 200 is conveyed, the amount of slurry dropped on the carrier 200 can be controlled by controlling the conveying speed of the conveying belt, so that the finally obtained flaky particles can have a preferable thickness. Specifically, the thickness of the finally obtained textured platelet particles in this example was between 0.5mm and 2.0 mm.

Referring to fig. 1 and 2, in one embodiment of the present invention, a feeding device 30 includes a plurality of feeding tanks 31 and a plurality of conveying pipes 32, where the plurality of conveying pipes 32 are in one-to-one correspondence with the plurality of feeding tanks 31, so that each conveying pipe 32 respectively conveys one color of slurry, and by providing the plurality of feeding tanks 31, each feeding tank 31 can convey one color of slurry to a slurry spraying device 20, and the slurries of multiple colors can be sprayed onto the surface of a carrier 200, so that multi-color particles can be finally prepared; further, the multicolor slurry is conveyed respectively through the plurality of feeding barrels 31, the multicolor slurry is not mixed during conveying, the subsequent recovery of the redundant slurry after spraying can be facilitated, the utilization rate of the slurry is improved, and waste is avoided.

Wherein the feeding device 30 may comprise 2-5 feeding barrels 31 and corresponding conveying pipes 32; further, the flow rate of the slurry was controlled to 30s-50s by the outflow time measured by the coating-4 cup. Since the flow rate of the slurry reflects its viscosity, the greater the flow rate, the greater the viscosity. When the flow rate is too large, the slurry is thick, and is not easy to flow out of the slurry spraying holes 221 of the slurry spraying device 20 during subsequent slurry spraying, and when the flow rate is too small, the slurry with various colors drops onto the carrier 200 and is combed and scraped by the combing and scraping device 40, excessive mixing is easy to occur, and color mixing is caused to lose obvious pattern textures.

Referring to fig. 2 and 3, in one embodiment of the present invention, the slurry spraying device 20 includes a first driving mechanism 21, a plurality of slurry spraying pieces 22 and a plurality of slurry receiving pieces 23, where the plurality of slurry spraying pieces 22 are respectively configured to receive slurry conveyed by a conveying pipeline 32, and the plurality of slurry receiving pieces 23 are located below the plurality of slurry spraying pieces 22 along the Z direction and are disposed in a one-to-one correspondence with the plurality of slurry spraying pieces 22, and the first driving mechanism 21 is connected to the plurality of slurry spraying pieces 22 or the plurality of slurry receiving pieces 23, so that the plurality of slurry spraying pieces 22 and the plurality of slurry receiving pieces 23 can relatively move along the conveying direction of the conveying device 10, so that the plurality of slurry spraying pieces 22 and the plurality of slurry receiving pieces 23 can be in a state of being stacked up and down or being staggered, so that, when the plurality of slurry spraying pieces 23 and slurry spraying pieces 22 are in a state of being staggered, slurry spraying pieces 22 can flow out of the slurry spraying pieces 22 can be applied to the surface of the carrier 200; when the slurry receiving piece 23 is located below the slurry spraying piece 22, slurry flowing out of the slurry spraying piece 22 can be received, so that intermittent slurry spraying of the slurry spraying piece 22 to the carrier 200 is realized, the slurry can have smaller quantity on the carrier 200, when the slurry falls on the carrier 200, the slurry naturally flows on the carrier 200 by means of the flowing property of the slurry and reaches a gradually flat state, the slurries with various colors form small-colored patterns with various colors, the respective color property is maintained, and disordered mixing among the various colors is reduced.

It will be appreciated that the transfer conduit 32 is required to transfer slurry to the shower 22 at this point, and thus the transfer conduit 32 is positioned above the shower 22 in the Z-direction so that slurry transferred by the transfer conduit 32 can be poured into the shower 22 by its own weight.

For convenience of description, the present embodiment defines the conveyance direction of the conveyance device 10 as the Y direction, the vertical direction as the Z direction, and the width direction of the shower 22 or the pulp receiving 23 as the X direction. In order to enable the slurry conveyed by the conveying pipeline 32 to flow onto the slurry spraying piece 22 more uniformly, the slurry spraying device 20 may further include an X-direction driving mechanism 80, where the X-direction driving mechanism 80 is connected to the plurality of conveying pipelines 32 and is used for driving each conveying pipeline 32 to move along the X direction, so that, under the driving of the X-direction driving mechanism 80, the conveying pipelines 32 are driven to move along the X direction, the conveying pipelines 32 can uniformly flow the slurry to each region of the slurry spraying piece 22, so that the slurry can be spread on the slurry spraying piece 22 more uniformly, each region of the slurry spraying piece 22 can be guaranteed to have a certain amount of slurry flowing down, so that each region of the carrier 200 can receive the slurry, the slurry can cover each region of the carrier 200, and the order of patterns is guaranteed.

The X-direction driving mechanism 80 may be a driving motor and a conveying manner of the conveying belt 81, and drives the conveying belt 81 to rotate by driving of the driving motor, so as to drive the conveying pipeline 32 connected to the conveying belt 81 to move.

Referring to fig. 2 and 3, in one embodiment of the present invention, in order to avoid stacking of the slurry on the slurry spraying member 22 and the slurry receiving member 23, the openings of the slurry spraying member 22 and the slurry receiving member 23 gradually decrease toward the carrier 200, that is, the slurry spraying member 22 and the slurry receiving member 23 may have a U-shaped, crescent-shaped or D-shaped cross section along the YZ plane, and the bottom wall of the slurry spraying member 22 is provided with a slurry spraying hole 221, so that the slurry spraying member 22 can have an arc-shaped smooth inner wall, and the slurry can flow downward along the arc-shaped inner wall, that is, when the slurry flows from the conveying pipeline 32 to the slurry spraying member 22 or when the slurry flows from the slurry spraying member 22 to the slurry receiving member 23, the slurry can flow downward automatically along the side walls of the slurry spraying member 22 and the slurry receiving member 23, so as to avoid stacking on the side walls of the slurry spraying member 22 and the slurry receiving member 23, and the slurry flowing downward together can be facilitated to flow out from the slurry spraying hole 221 located at the bottom wall.

The size of the aperture of the slurry spraying holes 221 and the density of the spacing between the slurry spraying holes 221 can also be set to control the amount of slurry dropped on the carrier 200, the aperture range of the slurry spraying holes 221 in this embodiment is 2.0mm-8.0mm, the spacing range of each adjacent slurry spraying holes 221 is 10.0mm-50.0mm, and the slurry is arranged in a straight line in the X direction, so that the slurry is prevented from being difficult to flow out of the slurry spraying piece 22 when the aperture is too small, and the slurry is prevented from being excessively spread when too fast drops on the carrier 200 when the aperture is too large, so that fine pattern textures are difficult to be formed in the subsequent carding process of the carding device 40.

It will be appreciated that the purpose of the connector 23 of the present embodiment is to intermittently block the linear curtain of slurry flowing from the bottom of the shower 22, thereby causing the linear flow to become intermittent drops. Specifically, the first driving mechanism 21 of the present embodiment is connected to the slurry receiving member 23, and the first driving mechanism 21 may be a driving motor and a crank driving manner, where the driving motor periodically drives the slurry receiving member 23 to move under the slurry spraying member 22 at a predetermined frequency, so as to realize intermittent slurry spraying of the slurry spraying member 22. As will be appreciated, the slurry received by each of the slurry receiving members 23 is able to flow back into the corresponding feed barrel 31 by the return flow of the recovery conduit, thereby allowing the slurry to be reused and reducing production costs.

Referring to fig. 4-9, in one embodiment of the present invention, the scraping device 40 includes a second driving mechanism 41 and a scraping member 42, where the second driving mechanism 41 is used to drive the scraping member 42 to move to realize scraping of linear textures on the tile, so that the scraping member 42 moves, such as linear motion, circular rotation, or curved motion, under the driving of the second driving mechanism 41, to thereby comb the multi-color paste on the carrier 200 under the scraping member 42, so that the multi-color paste presents linear textures, and then is dried by the drying device 50, so that a fine-textured tile body can be obtained, and thus, the tile body can be used to make tiles with fine linear textures in the following steps, thereby increasing the diversity of tile textures.

The second driving mechanism 41 may be a motor driving manner, for example, driving the scraping element 42 to move along a linear direction, so as to obtain a linear texture on the slurry, for example, as shown in fig. 4, by driving the first driving motor 411, the scraping element 42 is moved along a linear direction, so as to obtain a linear texture, as shown in fig. 5; or the second driving mechanism 41 includes not only the first driving motor 411 but also the second driving motor 412, please refer to fig. 6, the second driving motor 412 drives the scraping member 42 to rotate so as to obtain a circular or arc texture, please refer to fig. 7, or the first driving motor 411 and the second driving motor 412 can both move at the same time so as to drive the scraping member 42 to obtain an arc linear texture; or in the case that the first driving motor 411 and the second driving motor 412 are both disposed, the second driving mechanism 41 further includes a transmission link 422, please refer to fig. 8, and by disposing the transmission link 422, the scraping member 42 is deviated from the rotation center, so that the scraping member 42 can be driven to perform scraping by the second driving motor 412 or the second driving motor 412 and the first driving motor 411 at the same time, so as to obtain a curved texture, please refer to fig. 9, or a combination manner of straight line and rotation is adopted, so as to obtain a linear texture with more combination types, so that the pattern of the tile prepared later can be diversified.

Wherein, a plurality of scraping teeth 421 are disposed on the comb scraping member 42, the width range of the scraping teeth 421 is 0.5mm-5.0mm along the width direction of the comb scraping member 42, that is, along the X direction, the interval range between every two adjacent scraping teeth 421 is 2.0mm-10.0mm, so, when the slurry with different colors dropping on the carrier 200 is combed and scraped into linear textures by the scraping teeth 421, patterns with different textures can be realized by adjusting the density of the scraping teeth 421 and the width of the single scraping teeth 421.

In some embodiments of the present invention, after the above-described brushing step is completed, the textured multi-color slurry is dried in the next step using the drying device 50. The heat source of the drying device 50 may be electrothermal infrared radiation or kiln waste heat utilization, so as to heat and dry the slurry layer on the surface of the carrier 200, and meanwhile, the carrier 200 is not excessively heated, thereby achieving the effect of energy saving.

After the drying step is completed, the slurry layer having the original fluidity is changed into a sheet having a solid shape, and in the next step, the sheet is crushed from the carrier 200 by the cutter 70.

Specifically, when the sheet is crushed in this embodiment, the method includes two steps: the splitting apparatus 70 includes a stripping unit 71 and a sieving unit 72, the stripping unit 71 and the sieving unit 72 are sequentially disposed along the conveying direction of the conveying apparatus 10, the stripping unit 71 is used for splitting and stripping the sheet body on the carrier 200 to obtain a primary crushed pulp sheet, and the sieving unit 72 is used for crushing and sieving the primary crushed pulp sheet to obtain sheet particles.

The stripping unit 71 strips the sheet from the carrier 200 by a stripping roller, and can primarily crush the sheet while stripping to obtain primarily crushed pulp, and the primarily crushed pulp is conveyed to the screening unit 72 for screening and crushing.

The screening unit 72 of this embodiment adopts a roller cage screen, and the sharp protrusions are arranged in the roller cage screen to crush the pulp sheets in the roller cage screen, so that the sharp protrusions in the roller cage screen impact and crush the pulp sheets with large size in the process of driving the roller cage screen to obtain small-size sheet particles, the sheet particles have fine textures, and the sheet particles fall out and are collected through the screen holes. Wherein the size of the finally obtained small-sized particles is between 2mm and 10 mm.

Finally, when the flaky particles with the fine linear textures are obtained and used for manufacturing ceramic tiles, the flaky particles are directly pressed into green bodies or the flaky particles and ceramic powder are mixed and pressed into green bodies, and then the green bodies are dried and sintered to obtain the whole ceramic tiles with the fine linear texture pattern effect.

The grain with linear texture produced by the production line of this embodiment has the following advantages over the grain produced in the prior art:

compared with the conventional powder pressing and forming grain pattern, the present embodiment adopts different color slurry to drop and spread on the carrier 200, and then forms linear grains through the combing and scraping of the combing and scraping device 40, under the action of the liquid surface tension, the different color slurry can flow and migrate easily, and finally the combing and scraping forms the pattern grains with higher fineness. When the flaky particles with fine linear textures in the embodiment are prepared to form the ceramic tile in the follow-up process, the linear textures of the particles can be linear, or curved, or a combination of linear and curved, and besides the surface of the particles is provided with pattern textures, the particles are provided with pattern textures on the section and the section, and the particles are randomly distributed, occupied or staggered in different forms through random cloth, so that any surface of the ceramic tile shows the pattern texture effect formed by the irregular linear texture particles; the pattern texture effect of the tile finally prepared in this example is shown in fig. 10 and 11.
