[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 3 As shown in the figure, a specific embodiment of the present invention provides a pattern forming device for artificial quartz slabs, including a frame base 1. The frame base 1 is provided with a movable connecting component 2, a feeding hopper 3, and a rotary drive mechanism 4. The movable connecting component 2 is connected to an external moving device for driving the frame base 1 to move. The lower part of the frame base 1 is provided with a rotating disk 11 and a color spraying mechanism 5. The rotating disk 11 is provided with a cutting device 6 and three discharge hoppers 7 spaced along the circumferential direction. The discharge ends of the three discharge hoppers 7 have different discharge diameters. The cutting device 6 is used to cut and groove the laid material layer. The rotary drive mechanism 4 is connected to the rotating disk 11 and is used to drive the rotating disk 11 to rotate so that the corresponding discharge hopper 7 rotates to a position corresponding to the feeding hopper 3. At this time, the discharge hopper 7 is connected to the feeding hopper 3. The discharge hopper 7 is used to fill the grooved area with the raw material in the feeding hopper 3, and the color spraying mechanism 5 is used to color the filler.

[0025] The mobile connection component 2 of this equipment is adapted to connect with an external mobile device, which can drive this equipment or the frame base 1 to move along a specified path to facilitate automatic cutting, grooving, filling, and coloring operations. The external mobile device is preferably a multi-axis robotic arm, but is not limited to this.

[0026] When grooving is required, the external moving device can sequentially control the frame base 1 to move along the corresponding pattern path according to the preset filling coloring pattern sequence and pattern path data. This allows the cutting device 6 and the discharge hopper 7 on the frame base 1 to move above the material layer. During the grooving movement, the cutting blade 62 of the cutting device 6 moves downwards, and the horizontally moving cutting device 6 can cut grooves of different widths into the laid material layer to form the required patterned grooves. Since different pattern path data correspond to different width grooving operations, that is, grooves of different or the same width and their path data are known in the preset data, they can be arranged in sequence according to the width to obtain the filling coloring pattern sequence. Then, according to the sequence relationship, the corresponding pattern path data can be retrieved to control the cutting device to cut grooves of the corresponding width on the material layer. When the filler needs to be colored, the external moving device also controls the frame base 1 to move along the direction of the corresponding width of the channel according to the preset filler coloring pattern sequence and pattern path data. For example, the frame base 1 is controlled to move along the direction of the corresponding width of the channel according to the channel and its path data arranged in sequence according to the width. At the same time, the rotary drive mechanism 4 rotates the feed hopper with the corresponding discharge diameter to connect with the feed hopper 3 to realize the corresponding filler preparation work. During the movement of the filler, the raw material falls from the feed hopper into the channel. That is, the discharge diameter of the current feed hopper 7 is slightly greater than or equal to the slot width. The raw material is discharged from the feed hopper 7 with the discharge diameter to fully fill the current channel. At the same time, the color spraying mechanism 5 sprays the material of the required color to the filler to realize the filler coloring work. When all the slots have completed the filler coloring work, the required shape and color pattern will be formed on the material layer. Subsequently, the corresponding quartz pattern plate can be obtained by extrusion molding. The present invention can effectively reduce the adverse effects caused by human factors through the above-mentioned method, and can improve the processing accuracy, processing efficiency, processing quality and pattern aesthetics of quartz plates.

[0027] Preferably, in this embodiment, the discharge diameters of the discharge ends of the three discharge hoppers 7 are, but are not limited to, 30mm, 40mm, and 60mm.

[0028] Preferably, the number of discharge hoppers 7 can be adjusted according to actual needs.

[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, the frame base 1 is also equipped with a discharge switch mechanism 8, which is located near the feed hopper 3. The discharge switch mechanism 8 includes a switch plate 81 and a drive device 82. The switch plate 81 is located between the rotating disk 11 and the discharge end of the feed hopper 3. The rotating disk 11 is provided with connecting holes 71 that correspond one-to-one with the discharge hoppers 7. The connecting holes 71 are connected to the discharge port of the feed hopper 3. The drive device 82 is connected to the switch plate 81 and is used to drive the switch plate 81 to move, so as to open or close the discharge port of the feed hopper 3. When the equipment is in its initial state or before cutting and grooving work is to be carried out, the drive device 82 drives the switch plate 81 to close the discharge port of the feed hopper 3, so that the raw material cannot enter the corresponding discharge hopper 7 through the connecting holes 71 of the rotating disk 11. At this time, the frame base 1 and the cutting device 6 can be driven to perform grooving work along the required grooving path. When filling is required, the rotating drive mechanism 4 can drive the rotating disk 11 to rotate, so that the corresponding discharge hopper 7 rotates to below the feed hopper 3. At this time, the drive device 82 drives the switch plate 81 to open the discharge port of the feed hopper 3, so that the feed hopper 3 and the discharge hopper 7 are connected, and raw materials with the corresponding outlet diameter can be discharged to fully fill the corresponding channel.

[0030] Preferably, the driving device 82 includes a switch driving cylinder, and a connecting plate 83 is provided on the switch plate 81. The driving end of the switch driving cylinder is connected to the connecting plate 83. The switch driving cylinder can drive the switch plate 81 to move, thereby opening or closing the discharge port of the feed hopper 3.

[0031] To achieve a fixed connection with an external mobile device, such as Figure 1 and Figure 3 As shown, the movable connection assembly 2 includes a housing 21 and a mounting connection plate 22. The housing 21 covers the frame base 1, and the mounting connection plate 22 is provided on the top of the housing 21. The mounting connection plate 22 is connected to the external movable device to realize the fixed connection between the device and the external movable device. The feeding hopper 3 is provided on one side of the housing 21. The rotary drive mechanism 4 and the feeding seat 13 are provided inside the housing 21. The feeding seat 13 is provided with an upwardly extending feeding pipe 14. The feeding pipe 14 is embedded in the feeding hopper 3. The two ends of the feeding pipe 14 are respectively connected to the discharge port of the feeding hopper 3 and the communication hole 71 of the rotating disk 11, so that the raw material can be smoothly fed into the discharge hopper 7. The switch plate 81 is located between the rotating disk 11 and the feeding seat 13. The drive device 82 can drive the switch plate 81 to open or close the feeding pipe 14 or the discharge port of the feeding hopper 3.

[0032] Preferably, such as Figure 4As shown, the feed seat 13 is provided with a guide groove 15, which is connected to the feed pipe 14. The switch plate 81 is embedded in the guide groove 15 and can move back and forth along the guide direction of the guide groove 15 so that the switch plate 81 can accurately realize the switching operation.

[0033] In order to achieve the rotation of the rotating disk 11, such as Figure 1 and Figure 3 As shown, the rotary drive mechanism 4 is located in the middle of the rotating disk 11. The rotary drive mechanism 4 includes a rotary motor 41 and a rotating head 42. The rotary motor 41 is connected to the rotating head 42. The rotating head 42 is mounted on the rotating disk 11. When the rotary drive mechanism 4 drives the rotating head 42 to rotate, it can drive the rotating disk 11 to rotate, thereby realizing the switching execution of different functions.

[0034] Preferably, such as Figures 2 to 3 As shown, the cutting device 6 includes a cutting drive cylinder 61 and a cutting blade 62. The driving end of the cutting drive cylinder 61 is connected to the cutting blade 62 to drive the cutting blade 62 downward to different depths, and through horizontal movement, it can cut grooves of the required width. The cutting blade 62 is detachably mounted on the cutting drive cylinder 61. By replacing different types of cutting blades 62, different types of grooves can be formed to meet the diverse pattern processing needs of users.

[0035] To prevent material blockage in the discharge hopper 7, which has a larger outlet diameter, such as Figure 2 , Figure 5 and Figure 6 As shown, the rotating disk 11 is also equipped with a stirring drive motor 16 and a stirring screw 17. The stirring screw 17 is respectively installed in two discharge hoppers 7 with larger outlet diameters. One end of the stirring screw 17 is inserted into the discharge end of the discharge hopper 7. The drive part 161 of the stirring drive motor is connected to the rotating part 171 of the corresponding stirring screw 17 through the synchronous belt 18 and the through hole 71 of the discharge hopper 7, so as to drive the stirring screw 17 to rotate. When the stirring screw 17 rotates, it can loosen the accumulated raw material in the discharge end of the discharge hopper 7, so as to facilitate the raw material to fall from the discharge end into the channel.

[0036] In order to create patterns with a variety of colors, such as Figures 2 to 3As shown, the spraying mechanism 5 is located near the feed hopper 3. The spraying mechanism 5 includes a connecting seat 51, a connecting rod 52, two spray guns 53, and a powder spraying gun 54. The connecting seat 51 and the connecting rod 52 are respectively installed on the lower part of the frame base 1. Both spray guns 53 are mounted on a first connecting part 55, which is hinged to one end of the connecting seat 51. Rotating the first connecting part 55 adjusts the spraying angle of the spray guns 53 to meet the user's actual needs. One end of the powder spraying gun 54 has a second connecting part 56, in which a rotating shaft 57 is embedded and rotatably connected. One end of the rotating shaft 57 is connected to the connecting rod 52 via a clamping component 58. Rotating the powder spraying gun 54 adjusts the spraying angle relative to the user's actual needs. The spraying directions of the spray guns 53 and the powder spraying gun 54 intersect with the discharge direction of the feed hopper to precisely act on the filler in the channel. The spray gun 53 and the powder sprayer 54 are connected to the corresponding pigment storage components through pipes. The spray gun 53 and the powder sprayer 54 can spray materials of different or the same color, and can be adjusted according to the user's actual needs.

[0037] Preferably, such as Figure 1 and 2 As shown, the lower part of the frame base 1 is also provided with a protective cover 9, and the lower part of the protective cover 9 is provided with an opening 91; the protective cover 9 can protect the cutting device 6, the discharge hopper 7 and the color spraying mechanism 5, and prevent them from being damaged by collision, thereby improving the safety of equipment use.

[0038] like Figure 7 As shown in the figure, a specific embodiment of the present invention also provides a method for pattern forming of artificial quartz plates, applied to the above-mentioned pattern forming equipment, including:

[0039] S101. When grooving is being performed, the external moving device controls the frame base to move sequentially according to the preset filling coloring pattern sequence and pattern path data.

[0040] It should be noted that channel and path data of different or the same width are acquired or set in real time to obtain pattern path data of corresponding width. The pattern path data is arranged in order according to the width to obtain the coloring pattern sequence of the filler. Then, the frame base is controlled to move along the corresponding path data according to the coloring pattern sequence and the pattern path data, so that the cutting device and discharge hopper on the frame base move above the material layer.

[0041] S102. During the grooving process, the cutting device drives the cutting blade to move downward and cuts grooves of different widths into the laid material layer to form the required patterned grooves.

[0042] It should be noted that during the grooving process, the cutting device can drive the cutting blade to move downwards and the external moving device can drive the cutting blade to move along the path direction, so as to cut grooves of different widths into the laid material layer to form the required patterned grooves.

[0043] S103. When performing filler coloring work, the rotary drive mechanism and the spraying mechanism are controlled to perform filler coloring work according to the preset filler coloring pattern sequence and pattern path data.

[0044] Specifically, the step of controlling the rotary drive mechanism and the spraying mechanism to perform filler coloring work according to the preset filler coloring pattern sequence and pattern path data includes:

[0045] Step 1: When the filler is being colored, the external moving device controls the frame to move along the corresponding width of the channel according to the preset filler coloring pattern sequence and pattern path data, and the rotary drive mechanism rotates the corresponding discharge diameter hopper to connect with the feed hopper.

[0046] It should be noted that when the filler is colored, the external moving device controls the frame to move along the corresponding width of the channel according to the preset filler coloring pattern sequence and pattern path data. At the same time, the rotation drive mechanism drives the rotating disk to rotate so that the discharge hopper with the corresponding discharge diameter is connected to the feed hopper, thereby realizing the corresponding filler preparation work.

[0047] Step 2: During the movement of the filler, the raw material falls from the hopper into the channel, and the color spraying mechanism sprays the material of the required color onto the filler to achieve the coloring of the filler.

[0048] It should be noted that during the movement of the filler, the raw material falls from the hopper into the channel. That is, the discharge diameter of the current discharge hopper is slightly greater than or equal to the width of the slot. The raw material is discharged from the discharge hopper with this discharge diameter to fully fill the current channel. At the same time, the color spraying mechanism sprays the material of the required color to the filler to achieve the coloring of the filler. After all the slots have completed the coloring of the filler, the required shape and color pattern will be formed on the material layer. Subsequently, the corresponding quartz pattern plate can be obtained by extrusion molding.

[0049] In summary, this invention can automatically cut the required patterned grooves into the laid material layer, and automatically fill and color the patterned grooves, thereby forming a variety of patterns on the material layer. This invention can effectively reduce the adverse effects caused by human factors, and compared with the prior art, it has higher processing precision, processing efficiency, processing quality and pattern aesthetics.

[0050] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
