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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] Please refer to Figures 1 to 6The present invention provides a granulation device for manufacturing decorative particles of imitation travertine bricks, comprising a frame 1, a driving device 2, a driving shaft 3, a driven shaft 4 and a particle coloring device; the frame 1 comprises a granulation chamber 11 and a receiving chamber 12, the granulation chamber 11 is located above the receiving chamber 12; the driving device 2 is arranged in the receiving chamber 12; the bottom of the granulation chamber 11 is provided with a feed opening connected to the receiving chamber 12; the top of the granulation chamber 11 is provided with a feeding opening; the particle coloring device is arranged at the feeding opening and is used to apply color paste to the material;

[0036] The driving shaft 3 and the driven shaft 4 are rotatably assembled in the granulation chamber 11, and the driving shaft 3 and the driven shaft 4 are arranged side by side; the driving device 2 is connected to the driving shaft 3 by transmission, and the driving shaft 3 and the driven shaft 4 are connected to each other by transmission through gears, and the driving shaft 3 is installed with a first squeezing roller 31; the driven shaft 4 is installed with a second squeezing roller 41;

[0037] The circumferential side wall of the first extrusion roller 31 is provided with a plurality of first extrusion grooves at intervals, and the circumferential side wall of the second extrusion roller 41 is provided with a plurality of second extrusion grooves at intervals; the first extrusion roller 31 and the second extrusion roller 41 are meshed with each other through the first extrusion groove and the second extrusion groove; and a plurality of texture protrusions 101 are distributed at the bottom of the first extrusion groove or the second extrusion groove.

[0038] The granulation equipment is provided with a first extrusion roller 31 and a second extrusion roller 41. In the specific operation, the staff puts the prepared powder into the particle coloring device; after the particle coloring device applies the color paste to the powder, the powder attached with the color paste enters the feeding port of the granulation chamber 11 from the particle coloring device; then, the driving device 2 drives the first extrusion roller 31 and the second extrusion roller 41 to rotate relative to each other through the driving shaft 3 and the driven shaft 4. When passing between the two rollers, the powder is extruded and formed in the granulation space formed by the first extrusion roller 31 and the second extrusion roller 41, pressed into decorative particles, and discharged with the rotation of the first extrusion roller 31 and the second extrusion roller 41. Since a plurality of texture protrusions 101 are distributed on the bottom of the first extrusion groove or the second extrusion groove, after extrusion, holes corresponding to the texture protrusions 101 will be formed on the pressed decorative particles. Moreover, the color paste is attached to the powder, making the decorative particles closer to the appearance of travertine and more natural.

[0039] By adopting the above structure, various hole shapes, such as round, oval, square, grid, etc., can be produced by replacing the first extrusion roller 31 or the second extrusion roller 41 with texture protrusions 101 of different shapes and sizes to meet the needs of different products. The hole shape on natural travertine can be simulated. Moreover, the color and amount of color paste can be selected according to the specific situation, so that the surface of the decorative particles can produce a unique texture and decorative effect, which is closer to the natural travertine appearance.

[0040] The driving device 2 includes a driving motor 21 and a speed reducer 22. The speed reducer 22 is arranged on the top of the frame 1, and the input shaft end of the speed reducer 22 is drivingly connected to the output shaft end of the driving motor 21 through a chain. The output shaft end of the speed reducer 22 is drivingly connected to the driving shaft 3 through a coupling.

[0041] With the above structure, the speed reducer is used to reduce the speed of the input shaft and increase the torque of the output shaft at the same time, converting the high-speed rotation of the input shaft of the driving motor 21 into a low-speed output more suitable for the operation of the equipment, and avoiding energy waste caused by too fast or too slow speed.

[0042] Furthermore, the particle coloring device includes a first connecting frame 51, a material receiving hopper 52, a color paste dispensing assembly 53, a first gear ring 54, a first driving gear 55 and a first driving member 56;

[0043] The first connecting frame 51 is placed above the feeding port; the material receiving hopper 52 is fixed to the inner ring of the first gear ring 54, and the first gear ring 54 is rotatably assembled in the middle of the first connecting frame 51; the material receiving hopper 52 passes through the first connecting frame 51 and is located above the feeding port; the first driving member 56 and the color paste dispensing assembly 53 are respectively arranged on the first connecting frame 51; the color paste outlet of the color paste dispensing assembly 53 faces the material receiving hopper 52; the first driving gear 55 is arranged at the driving end of the first driving member 56, and the first driving gear 55 meshes with the first gear ring 54.

[0044] Tooth teeth are provided on the outer periphery of the first gear ring 54. The first driving member 56 drives the first gear ring 54 to rotate through the first driving gear 55, thereby driving the material receiving hopper 52 to rotate with the central axis of the first gear ring 54 as the rotation axis. The first driving member 56 is specifically a motor, and the driving end of the motor can rotate clockwise or counterclockwise, so that the material receiving hopper 52 rotates clockwise or counterclockwise.

[0045] During operation, the staff first starts the first driving member 56 to make the material receiving hopper 52 rotate; then pours the prepared powder into the material receiving hopper 52 and starts the color paste dispensing assembly 53 at the same time. The color paste dispensing assembly 53 dispenses color paste onto the powder. Since the color paste dispensing assembly 53 is fixed to the first connecting frame 51 and the material receiving hopper 52 rotates with the central axis of the first gear ring 54 as the rotation axis, the mixing of the color paste and the powder is uneven, and the amount of color paste attached to the powder may be more or less, with randomness. After being extruded and formed by the first extrusion roller 31 and the second extrusion roller 41, decorative particles of different colors are formed, which can simulate different colors on natural travertine and make the decorative particles closer to natural travertine.

[0046] Even further, the color paste dispensing assembly 53 includes a telescopic driving member 531, a nozzle 532 and a color paste bucket 533;

[0047] The fixed end of the telescopic driving member 531 is arranged on one side of the first connecting frame 51. The driving end of the telescopic driving member 531 is arranged upward. The nozzle 532 is arranged at the driving end of the telescopic driving member 531. The input end of the nozzle 532 is communicated with the color paste bucket 533. The color paste outlet of the nozzle 532 faces the material receiving hopper 52.

[0048] The color paste bucket 533 is used for storing color paste. The nozzle 532 is communicated with the color paste bucket 533. The nozzle 532 can extract the color paste in the color paste bucket 533 and apply the color paste on the powder in the material receiving hopper 52 in a spraying or pouring manner. The telescopic driving member 531 is used to drive the nozzle 532 and the color paste bucket 533 to move in the vertical direction. The staff can change the distance between the nozzle 532 and the powder in the material receiving hopper 52 according to the actual situation to adjust the application effect of the color paste; or during the process of the nozzle 532 applying the color paste, the nozzle 532 can be moved upward or downward through the telescopic driving member 531 to make the mixing of the color paste and the powder more uneven, so as to form more decorative particles with different colors.

[0049] Preferably, the particle coloring device further includes a second connecting frame 57, a second gear ring 58, a second transmission gear 59 and a second driving member 50;

[0050] The second connecting frame 57 is arranged on the outer periphery of the feeding port. The second gear ring 58 is rotatably assembled on the second connecting frame 57. The first connecting frame 51 is connected to the second connecting frame 57. The material receiving hopper 52 sequentially passes through the first connecting frame 51 and the second connecting frame 57 and is arranged above the feeding port; the second driving member 50 is arranged on the second connecting frame 57; the second transmission gear 59 is arranged at the driving end of the second driving member 50, and the second transmission gear 59 meshes with the second gear ring 58.

[0051] The second driving member 50 is specifically a motor. The second transmission gear 59 and the second gear ring 58 are engaged for transmission, driving the second gear ring 58 and the first connecting frame 51 to rotate around the axis of the second gear ring 58, so as to drive the color paste application assembly 53 to rotate.

[0052] The first gear ring 54 and the second gear ring 58 are coaxially arranged. The rotation structures of the first gear ring 54 and the second gear ring 58 are independent of each other and will not interfere with each other. Therefore, the rotation direction of the color paste application assembly 53 and the rotation direction of the material receiving hopper 52 can be the same or opposite, which can simulate natural random textures and meet the requirements of the diversification of the colors of the travertine products.

[0053] Specifically, the material receiving hopper 52 includes a material receiving hopper body 521, a discharging driving member 522, and a discharging plate 523; the first toothed ring 54 is sleeved on the outer periphery of the material receiving hopper body 521; a discharging port is provided at the bottom of the material receiving hopper body 521, the discharging plate 523 is hinged to one side of the discharging port, one end of the discharging driving member 522 is hinged to the side wall of the material receiving hopper body 521, and the other end of the discharging driving member 522 is hinged to the discharging plate 523.

[0054] In a specific embodiment of the present invention, the discharging port is rectangular, discharging plates 523 are provided on both sides of the discharging port, discharging driving members 522 are provided on both sides of the material receiving hopper body 521, and the opening and closing angles of the two discharging plates 523 are controlled by the discharging driving members 522 on the corresponding sides.

[0055] By controlling the inclination angle of the discharging plate 523 through the discharging driving member 522, the size of the discharging port can be controlled, thereby controlling the discharging amount. The staff can adjust the discharging amount of the material receiving hopper 52 according to the actual situation, and cooperate with the first toothed ring 54 to drive the color paste application assembly 53 to rotate, so that the distribution of the color paste is more random, and the formed imitation travertine effect is more natural.

[0056] Optionally, the cross-section of the texture protrusion 101 is one or more of a circle, a circular ring, a polygon, and a polygon ring.

[0057] In a specific application, the texture protrusion 101 is formed by mechanical cutting or milling.

[0058] In some embodiments of the present invention, the groove widths of the first extrusion groove and the second extrusion groove are 2-15 mm, the depths are 5-10 mm, and the height of the texture protrusion is 1-5 mm. In some embodiments of the present invention, texture protrusions 101 with a cross-section of a cylinder or a circular ring are spacedly distributed at the bottom of the first extrusion groove or the second extrusion groove. In a specific embodiment, the cross-section of the texture protrusion 101 is circular, that is, the texture protrusion 101 is cylindrical, and after the material is extruded, decorative particles with circular holes are formed. In another specific embodiment, the cross-section of the texture protrusion 101 is a circular ring, and after the material is extruded, decorative particles with a circular cross-section are formed.

[0059] In some embodiments of the present invention, texture protrusions 101 with a cross-section of a polygon are spacedly distributed at the bottom of the first extrusion groove or the second extrusion groove. In a specific embodiment, the cross-section of the texture protrusion 101 is triangular, and after the material is extruded, decorative particles with triangular holes are formed. As a simple replacement, the cross-section of the texture protrusion 101 can also be replaced with a square, a pentagon, a hexagon, etc.

[0060] In another specific embodiment, the cross-section of the texture protrusion 101 is a triangular loop. After the material is extruded, decorative particles with a triangular cross-section are formed.

[0061] Optionally, the texture protrusion 101 is a crack-like linear protrusion or a grid-like protrusion.

[0062] In some embodiments of the present invention, a number of crack-like linear protrusions are distributed at intervals on the bottom of the first extrusion groove or the second extrusion groove.

[0063] In a specific embodiment, the crack-like linear protrusion is in a zigzag shape. The crack-like linear protrusion is formed by connecting multiple straight-segment protrusions. There is usually a turning point between every two straight segments, resulting in a change in angle. After the material is extruded, decorative particles with an irregular crack shape are formed.

[0064] In another specific embodiment, the crack-like linear protrusion is in an irregular wavy shape. The crack-like linear protrusion is formed by connecting multiple arc-shaped protrusions with different curvatures. After the material is extruded, an irregular crack shape with curves is formed. As a simple replacement, the crack-like linear protrusion can also be in a regular wavy shape. After the material is extruded, decorative particles with a repetitive undulating and curved texture shape are formed.

[0065] In some embodiments of the present invention, grid-like protrusions are distributed on the bottom of the first extrusion groove or the second extrusion groove. After the material is extruded, block-shaped decorative particles are formed.

[0066] Specifically, a discharge port 121 is provided on the side wall of the accommodation chamber 12; a discharge screen 122 is further provided in the accommodation chamber 12 below the feeding port. The discharge screen 122 is fixed to the side wall of the accommodation chamber 12; the discharge screen 122 is inclined towards the discharge port 121, and one end of the discharge screen 122 is connected to the discharge port 121.

[0067] With the above structure, the extruded material is conveyed to the discharge port 121 through the discharge screen 122. Since the discharge screen 122 is inclined, the material slides to the discharge port 121 under the influence of gravity and is then discharged from the discharge port 121 out of the granulating equipment. At the same time, the discharge screen 122 can also screen out materials or debris with a particle size smaller than the filter holes, avoiding the problem that the particle size of the material is too fine and affecting the subsequent texture effect of the imitation travertine brick.

[0068] In a specific embodiment of the present invention, a receiving box 123 is further provided in the accommodation chamber 12, and the receiving box 123 is arranged below the discharge screen 122.

[0069] With the above structure, the powder and debris filtered out by the discharge screen 122 pass through the filter holes of the discharge screen 122 and fall into the receiving box 123 below for collection, which can effectively collect the screened materials, prevent the materials from scattering or losing, and avoid waste.

[0070] Specifically, a feeding port is provided at the top of the granulation chamber 11 , a feeding hopper 111 is installed on the periphery of the feeding port, and a discharge port of the receiving hopper 52 is located directly above the feeding hopper 111 .

[0071] With the above structure, powder can be fed into the granulation chamber 11 from above the granulation chamber 11, which is convenient for the staff to add powder. The feed hopper 111 can collect the powder to the feed port, ensuring that the material enters the granulation chamber 11 in a more efficient and orderly manner.

[0072] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific embodiments of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
