[0002] At the intersection of contemporary art and technology, 3D printing technology is gradually changing the traditional sculpture creation method. The ceramic 3D printing technology extrudes a ceramic paste with a relatively high water content and stacks it into a ceramic component. Since the ceramic paste with a relatively high water content has a certain fluidity, if the structure of the printed ceramic component is too high, under the influence of gravity, the ceramic structure at the bottom is prone to collapse, affecting the overall printing effect. And the existing ceramic 3D printers need to control the speed of the 3D printing head to maintain the uniformity and stability of the clay stacking process. Otherwise, there will be disconnection and gaps during the clay stacking process, affecting production efficiency, component accuracy, and surface quality. Summary of the Invention

The slicing module is used to convert the concave-convex three-dimensional digital model into printing path data according to the set slicing parameters. The parameter setting module is used to provide the slicing parameters for the slicing module, so that when the digital image scanned by the scanner is output to the 3D model generation module, the 3D model generation module generates a corresponding concave-convex three-dimensional digital model and outputs it to the slicing module. The slicing module slices the digital model and outputs the printing path data to the main controller. Then, the main controller controls the X-axis drive module, the Y-axis drive module, and the Z-axis drive module to drive the 3D printing head to perform 3D printing according to the printing path data.

[0013] Through the above technical solution, the 3D model generation module and the slicing module are used to provide printing path data for the 3D printing head, ensuring the continuity and integrity during the clay sculpture process and achieving the precise replication of the clay sculpture.

[0014] As a further description of the 3D printing numerically controlled intelligent ceramic clay stacking sculpture device of the present invention, preferably, a cylindrical rod is integrally connected to the 3D printing head, and an annular air outlet component of the fan device is fixedly connected to the outside of the cylindrical rod. The lower end of the annular air outlet component is an annular lifting platform, and a circle of air outlets is provided around the bottom of the annular lifting platform. The air outlets blow air in the direction and reverse direction of the connection line with the annular center point.

[0015] Through the above technical solution, the annular lifting platform can extend or retract relative to the annular air outlet component by means of hydraulic pressure, pneumatic pressure, electric power, etc., to adjust the distance between the air outlet and the workbench, ensuring that during the process of the mud line ejected by the 3D printing head being stacked into a clay sculpture, the air outlet can provide a gentle breeze to dry the clay sculpture, avoiding collapse or soft and spongy deformation under the pressure during the clay sculpture process. The air outlets blow air back and forth in the direction and reverse direction of the connection line with the annular center point, avoiding collapse caused by uneven drying.

[0016] As a further description of the 3D printing numerically controlled intelligent ceramic clay stacking sculpture device of the present invention, preferably, the computer includes a main controller and a fan control module.

[0019] Through the above technical solutions, after the fan start-stop module starts the fan device, the infrared sensor starts to detect the distance between the air outlet and the workbench and transmits it to the main controller. The main controller controls the lifting control module to adjust the air outlet to a suitable position above the workbench. During the printing process of the 3D printing head, the main controller can automatically adjust the height of the air outlet relative to the clay sculpture according to the distance between the air outlet and the clay sculpture detected by the infrared sensor in real time, ensuring that the gentle breeze blown out by the air outlet covers all sides of the clay sculpture and avoiding the local temperature of the clay sculpture being too high due to the air outlet being too close to the clay sculpture.

[0020] The beneficial effects of the present invention are as follows: The present invention uses a scanner to scan the image of an object onto a computer.

Detailed Embodiments

[0028] In order to further understand the structure, features and other purposes of the present invention, the following is a detailed description with reference to the attached preferred embodiments and accompanying drawings. The embodiments described by these drawings are only used to illustrate the technical solutions of the present invention and do not limit the present invention.

[0029] In the first embodiment of the present invention, as Figure 1 shown, the present invention provides a 3D printing numerically controlled intelligent ceramic clay stacking sculpture device, including a scanner 1, a computer 2, a 3D printing head 3, a fan device 4, a numerically controlled pneumatic rotating disk 5 and a mechanical lifting device 6.

[0030] The scanner 1 is electrically connected and signal-connected to the computer 2. The scanner 1 scans the item to be sculpted and converts it into a digital image recognizable by the computer 2, and then the scanner 1 transmits the digital image to the computer 2 for processing.

[0031] The computer 2 is electrically and signal - connected to the 3D printing head 3. The computer 2 converts the digital image scanned by the scanner 1 into a concave - convex three - dimensional digital model to obtain model data. Among them, the computer 2 uses algorithms or software in the prior art to realize the conversion from the digital image to the concave - convex three - dimensional digital model, and displays it in the computer 2. The concave - convex three - dimensional digital model can also be further processed by the computer 2 to improve the accuracy of the model to be printed. The 3D printing head 3 sprays ceramic mud according to the model data and the control of the computer 2 for 3D printing. Among them, the computer 2 controls the 3D printing head 3 to simulate the mud - stacking process in traditional clay sculpture according to the processing result of the digital image. The 3D printing head 3 realizes clay sculpture in the way of simulated mud - line accumulation.

[0032] The blower device 4 is installed at the top of the 3D printing head 3, and the blower device 4 is electrically and signal - connected to the computer 2. The blower device 4 is used to blow - dry the clay sculpture according to the control of the computer 2. During the 3D printing process, the mud - lines sprayed by the 3D printing accumulate to form a clay sculpture. When the moisture content of the mud - lines sprayed by the 3D printing is too high, the clay sculpture is prone to collapse or soft and spongy deformation. When the moisture content of the mud - lines sprayed by the 3D printing is too low, it is easy to clog the 3D printing head 3. Therefore, by installing the blower device 4 at the top of the 3D printing head 3, micro - blowing drying is realized, avoiding collapse or soft and spongy deformation under the pressure of the clay - sculpture process.

[0033] The numerically - controlled pneumatic rotating disk 5 is installed at the bottom of the workbench 7 opposite to the 3D printing head 3, and the numerically - controlled pneumatic rotating disk 5 is electrically and signal - connected to the computer 2. The numerically - controlled pneumatic rotating disk 5 is used to adjust the angle conversion of the clay sculpture according to the control of the computer 2. During the 3D printing process, the 3D printing head 3 generally adopts a layer - by - layer printing method, and the processing of the forms and details of the sculpture in different directions is not fine enough. Therefore, by setting the numerically - controlled pneumatic rotating disk, the angle conversion of the height of the clay sculpture can be realized, which is convenient for further printing the three - dimensional effect and details of the sculpture.

[0034] The mechanical lifting device 6 is electrically and signal - connected to the computer 2. The mechanical lifting device 6 is used to lift the 3D printing head 3 at a constant speed through the control of the computer 2. Since 3D printing realizes clay sculpture in the way of simulated mud - line accumulation, the speed control in the process of clay - sculpture accumulation is very important. Through the coordinated work of the printing mud - spraying head and the mechanical lifting device with uniform speed, the continuity and integrity in the clay - sculpture process are ensured, and the generation of disconnection and gaps is avoided.

[0035] The core of the 3D - printed numerically - controlled intelligent ceramic - mud - stacking sculpture device in this embodiment lies in combining traditional clay - sculpture art with modern 3D printing technology, and realizing the precise replication and innovative design of clay sculpture through digital means. It achieves this goal through the following steps:

[0036] 1) Image scanning: First, the item to be sculpted is scanned by a high-precision scanner 1 and converted into a digital image recognizable by a computer 2.

[0037] 2) Data processing: The computer 2 uses advanced algorithms to convert the scanned image into a concave-convex three-dimensional digital model. This process involves complex mathematical calculations and image processing techniques, all of which are existing technologies.

[0038] 3) 3D printing: The computer 2 transmits the processed digital model to a 3D printing head 3. The 3D printing head 3, according to the model data, precisely controls the ejected ceramic mud to simulate the mud stacking process in traditional clay sculpture. Preferably, the computer 2 controls the speed of the 3D printing head 3 to drift back and forth at 1.5 millimeters per second, precisely controlling the accumulation of the mud. This speed control is crucial for maintaining the uniformity and stability of the clay sculpture.

[0039] 4) Gentle air drying: A blower device 4 is installed on the top of the 3D printing head 3. During the process of the 3D printing head 3 ejecting mud lines in the way of simulating mud lines, the blower device 4 gently dries the clay sculpture.

[0040] 5) Fine processing: For the printing positions that require fine processing, first, the computer 2 controls the numerically controlled pneumatic rotating disk 5 to perform angle conversion, and then the 3D printing head 3, according to the model data, precisely controls the ejected ceramic mud.

[0041] It can be seen that in the present invention, the computer controls the speed of the 3D printing head to drift back and forth at 1.5 millimeters per second, precisely controlling the accumulation of the mud. This speed control is crucial for maintaining the uniformity and stability of the clay sculpture. Adding a tiny blower device on the top of the 3D printing head realizes gentle air drying, avoiding collapse or soft deformation under pressure during the clay sculpture process. Setting the numerically controlled pneumatic rotating disk can achieve angle conversion of the height of the clay sculpture, which is crucial for the three-dimensional effect and detail performance of the sculpture. The printing mud ejection head and the mechanical lifting device work together with a uniform speed, ensuring the continuity and integrity during the clay sculpture process and avoiding disconnection and gaps. The present invention combines traditional clay sculpture art with modern 3D printing technology, realizing precise replication and innovative design of clay sculpture through digital means, not only improving the efficiency of sculpture creation but also easily adjusting the shape and details of the sculpture through computer control.

[0042] In the second embodiment of the present invention, as Figure 2 shown, the computer 2 includes a main controller 21 and a speed setting module 22.

[0043] The speed setting module 22 is electrically and signal - connected to the main controller 21. The main controller 21 is respectively electrically and signal - connected to the X - axis driving module 31, the Y - axis driving module 32, and the Z - axis driving module 33. The X - axis driving module 31 and the Y - axis driving module 32 are respectively electrically and signal - connected to the 3D printing head 3. The Z - axis driving module 33 is electrically and signal - connected to the mechanical lifting device 6, and the mechanical lifting device 6 is connected to the 3D printing head 3. The speed setting module 22 is used to set the printing speed of the 3D printing head 3, so as to realize the control of the printing speed of the 3D printing head 3.

[0044] The implementation process of controlling the printing speed of the 3D printing head 3 in this embodiment is as follows: The printing speed is input by the speed setting module 22. Since the 3D printing head 3 generally prints layer by layer, and mainly controls the printing speed in the X - axis direction, the speeds in the Y - axis direction and the Z - axis direction need to match the speed in the X - axis direction to ensure that the entire printing process is carried out at a uniform speed. Therefore, the speed setting module 22 processes the input printing speed to obtain the actual speeds in the X - axis direction, the Y - axis direction, and the Z - axis direction, and transmits them to the main controller 21. Since the 3D printing head 3 of the present invention performs clay sculpture in the way of simulated mud line accumulation, the main controller 21 controls the X - axis driving module 31 and the Y - axis driving module 32 to drive the 3D printing head 3 to drift back and forth at a speed of 1.5 millimeters per second for printing, to ensure the uniformity and stability of the clay sculpture. At the same time, the main controller 21 controls the Z - axis driving module 33 to drive the mechanical lifting device 6 to drive the 3D printing head 3 to lift evenly. The uniformity and stability of 3D printing for clay sculpture are realized by controlling the printing speed of the 3D printing head 3.

[0045] In the third embodiment of the present invention, as Figure 2 shown, the computer 2 includes a main controller 21, a speed setting module 22, a speed adjustment module 23, and a printing start - stop module 24.

[0046] An encoder 34 is provided on the 3D printing head 3. The encoder 34 is respectively electrically and signal - connected to the speed adjustment module 23 and the main controller 21. The speed adjustment module 23 is respectively electrically and signal - connected to the speed setting module 22, the printing start - stop module 24, and the main controller 21. The printing start - stop module 24 is electrically and signal - connected to the main controller 21.

[0047] The encoder 34 is used to detect the vibration data and printing speed of the 3D printing head 3 during the printing process. The speed adjustment module 23 is used to adjust the printing speed of the 3D printing head 3 according to the vibration data and printing speed from the encoder 34. The printing start / stop module 24 is used to provide a printing start signal, a printing stop signal, and output a printing stop signal according to the feedback signal of the speed adjustment module 23. By the encoder 34, the vibration data and printing speed of the 3D printing head 3 are monitored in real time, and the printing speed can be adjusted when the vibration data and printing speed exceed the set range, so as to control the vibration data and printing speed within the set range, ensuring the uniformity and stability of the clay sculpture.

[0048] In this embodiment, the implementation process of controlling the vibration data and printing speed of the 3D printing head 3 is as follows: when the 3D printing head 3 starts printing, the encoder 34 is started simultaneously to detect the vibration data and printing speed of the 3D printing head 3 in real time, and output them to the speed adjustment module 23. When the printing speed is input by the speed setting module 22, the speed setting module 22 transmits the input printing speed to the speed adjustment module 23 as the set printing speed range. The speed adjustment module 23 obtains the set vibration data range from the main controller. When the vibration data and printing speed detected by the encoder 34 received by the speed adjustment module 23 exceed the set range, the speed adjustment module 23 adjusts the printing speed and transmits it to the main controller 21. The main controller 21 controls the X-axis drive module 31 and the Y-axis drive module 32 to adjust the printing speed according to the speed adjustment data.

[0049] When it is detected that the printing speed becomes slow, the speed adjustment module 23 adjusts the printing speed to the printing speed of the speed setting module 22, and when it is detected that the vibration data exceeds the set range, if the vibration data does not exceed the set range, the current speed is maintained for printing.

[0050] When it is detected that the vibration data exceeds the set range, the speed adjustment module 23 slows down the printing speed, and detects whether the vibration data returns to the normal vibration offset. If the vibration data returns to the normal vibration offset, in order to ensure the uniformity and stability of the clay sculpture, the speed adjustment module 23 modifies the set range of the printing speed to the slowed-down speed and maintains the current speed for printing.

[0051] In addition, the main controller 21 is provided with a counter and a timer. When the speed adjustment module 23 slows down the printing speed multiple times within a specified time, the speed adjustment module 23 sends a feedback signal to the printing start / stop module 24, and then the printing start / stop module 24 outputs a printing stop signal to the main controller 21. The main controller 21 controls the X-axis drive module 31, the Y-axis drive module 32, and the Z-axis drive module 33 to automatically stop operating.

[0052] After the printing speed is set by the speed setting module 22, the start / stop printing module 24 can manually control the X-axis drive module 31, the Y-axis drive module 32, and the Z-axis drive module 33 to drive the 3D print head 3 to start or stop printing.

[0053] In the fourth embodiment of the present invention, as Figure 3 shown, the computer 2 includes a main controller 21, a 3D model generation module 25, a slicing module 26, and a parameter setting module 27.

[0054] The scanner 1 is electrically connected and signal-connected to the 3D model generation module 25. The 3D model generation module 25 is electrically connected and signal-connected to the slicing module 26 and the main controller 21 respectively. The slicing module 26 is electrically connected and signal-connected to the parameter setting module 27 and the main controller 21 respectively. The parameter setting module 27 is electrically connected and signal-connected to the main controller 21. The main controller 21 is electrically connected and signal-connected to the X-axis drive module 31, the Y-axis drive module 32, and the Z-axis drive module 33 respectively.

[0055] The 3D model generation module 25 is used to generate a corresponding concave-convex three-dimensional digital model according to the digital image scanned by the scanner 1. The slicing module 26 is used to convert the concave-convex three-dimensional digital model into printing path data according to the set slicing parameters. The parameter setting module 27 is used to provide the slicing parameters for the slicing module 26.

[0056] The specific implementation process of providing printing path data for the 3D print head 3 in this embodiment is as follows: First, the digital image scanned by the scanner 1 is output to the 3D model generation module 25. Then, the 3D model generation module 25 generates a corresponding concave-convex three-dimensional digital model from the digital image according to the algorithm in the prior art and outputs it to the slicing module 26. Subsequently, the slicing module 26 performs slicing processing on the digital model according to the slicing parameters input by the parameter setting module 27, including the thickness of each layer of the clay sculpture, the coordinate values in the X-axis direction, the Y-axis direction, and the Z-axis direction, etc., and outputs the printing path data to the main controller 21. Finally, the main controller 21 controls the X-axis drive module 31, the Y-axis drive module 32, and the Z-axis drive module 33 to drive the 3D print head 3 to perform 3D printing according to the printing path data. By the 3D model generation module 25 and the slicing module 26, providing printing path data for the 3D print head 3 ensures the continuity and integrity during the clay sculpture process and realizes the precise replication of the clay sculpture.

[0057] In the fifth embodiment of the present invention, as Figure 4 and Figure 5As shown, a cylindrical rod is integrally connected to the 3D printing head 3. An annular air outlet component 41 of the fan device 4 is fixedly connected to the outside of the cylindrical rod. The lower end of the annular air outlet component 41 is an annular lifting platform 42. A circle of air outlets 43 is provided around the bottom of the annular lifting platform 42. The air outlets 43 blow air in the direction and reverse direction of the line connecting to the annular center point. The annular lifting platform 42 can extend or retract relative to the annular air outlet component 41 by means of hydraulic pressure, pneumatic pressure, electric power, etc., to adjust the distance between the air outlets 43 and the workbench 7. During the process of the mud line ejected by the 3D printing head 3 being stacked into a clay sculpture, the air outlets 43 can provide a gentle breeze to dry the clay sculpture, avoiding collapse or soft deformation under the pressure during the clay sculpture process. The air outlets 43 blow air in the swinging direction A and reverse direction B of the line connecting to the annular center point, that is, the air outlets 43 swing to a certain angle in the A direction and then swing to the B direction by the same angle, and swing back and forth for blowing, avoiding collapse caused by uneven drying.

[0058] In the sixth embodiment of the present invention, as Figure 6 shown, the computer 2 includes a main controller 21 and a fan control module 28. The fan control module 28 includes a fan start-stop module 281, a lifting control module 282, and an air outlet swing control module 283.

[0059] The fan start-stop module 281 is electrically connected and signal-connected to the main controller 21, and the main controller 21 is electrically connected and signal-connected to the fan device 4. The fan start-stop module 281 is used to provide a fan start signal and a fan stop signal for the fan device 4 to realize the manual control of the start and stop of the fan device 4.

[0060] The main controller 21 is electrically connected and signal-connected to the lifting control module 282, and the lifting control module 282 is electrically connected and signal-connected to the annular lifting platform 42. The lifting control module 282 is used to control the rising or falling of the annular lifting platform 42, so that before the printing starts, the main controller 21 controls the lifting control module 282 to drive the annular lifting platform 42 to adjust the position of the air outlets 43, realizing the automatic control of the lifting of the annular lifting platform 42, ensuring the precise control of the distance between the air outlets 43 and the workbench 7, and the air outlets 43 provide a gentle breeze to evenly dry the clay sculpture ejected and stacked by the 3D printing head 3, ensuring the continuity and integrity during the clay sculpture process.

[0061] The main controller 21 is electrically and signal - connected to the air outlet swing control module 283, and the air outlet swing control module 283 is electrically and signal - connected to the air outlet 43. The air outlet swing control module 283 is used to control the swing direction of the air outlet 43, so that the main controller 21 controls the air outlet 43 to swing and blow in the direction and reverse direction of the line connecting to the annular center point according to the signal of the fan start - stop module 281. By controlling the swing direction of the air outlet 43 through the air outlet swing control module 283, the automatic control of the swing of the air outlet 43 is realized. Different swing modes of the air outlet 43 can be adopted for different clay sculptures to ensure that the air outlet 43 provides gentle wind to evenly dry the clay sculptures.

[0062] In this embodiment, the implementation process of controlling the fan device 4 is as follows: First, start the fan device 4 through the fan start - stop module 281. The fan device 4 first adjusts the position of the air outlet 43. According to the set thickness of each layer of the clay sculpture, the main controller 21 controls the lifting control module 282 to drive the annular lifting platform 42 to rise or fall to an appropriate height. This height is at least such that the gentle wind blown out by the air outlet 43 can cover the clay sculpture ejected and stacked by the 3D printing head 3, ensuring that each surface of the clay sculpture is blown as much as possible. Then, the main controller 21 sets the swing mode of the air outlet 43 and controls the air outlet swing control module 283 to drive the air outlet 43 to execute. Preferably, as Figure 5 shown, after the air outlet 43 swings to a certain angle in the A direction and then swings in the B direction by the same angle, and swings and blows repeatedly to avoid collapse caused by uneven drying.

[0063] In addition, it can be set that after the main controller 21 receives the start signal of the fan start - stop module 281 and when the main controller 21 receives the print start signal of the print start - stop module 24, the main controller 21 controls the X - axis drive module 31, the Y - axis drive module 32, and the Z - axis drive module 33 to drive the 3D printing head 3 to start printing, so as to avoid the phenomenon of collapse or soft and deformed of the bottom layer of the clay sculpture when starting to print after the 3D printing head 3 starts printing. The start and stop of the fan device 4 are manually controlled through the fan start - stop module 281, and the position of the air outlet 43 is adjusted by driving the annular lifting platform 42 through the lifting control module 282, realizing the automatic control of the lifting of the annular lifting platform 42, ensuring the precise control of the distance between the air outlet 43 and the workbench 7. The air outlet 43 provides gentle wind to evenly dry the clay sculpture ejected and stacked by the 3D printing head 3, ensuring the continuity and integrity during the clay sculpture process. By controlling the swing direction of the air outlet 43 through the air outlet swing control module 283, the automatic control of the swing of the air outlet 43 is realized. Different swing modes of the air outlet 43 can be adopted for different clay sculptures to ensure that the air outlet 43 provides gentle wind to evenly dry the clay sculptures.

[0064] In the seventh embodiment of the present invention, as Figure 6As shown, an infrared sensor 44 is provided at the bottom of the annular lifting platform 42. The infrared sensor 44 is electrically connected and signal-connected to the main controller 21. The infrared sensor 44 is used to detect the distance between the air outlet 43 and the workbench 7, so that the main controller 21 controls the lifting control module 282 to drive the annular lifting platform 42 to adjust the position of the air outlet 43 according to the position of the air outlet 43 detected by the infrared sensor 44.

[0065] In this embodiment, after the fan start-stop module 281 starts the fan device 4, the infrared sensor 44 begins to detect the distance between the air outlet 43 and the workbench 7 and transmits it to the main controller 21. The main controller 21 controls the lifting control module 282 to adjust the air outlet 43 to a suitable position above the workbench 7. During the 3D printing process of the 3D printing head 3, the main controller 21 can automatically adjust the height of the air outlet 43 relative to the clay sculpture according to the distance between the air outlet 43 and the clay sculpture detected by the infrared sensor 44 in real time, ensuring that the gentle breeze blown out by the air outlet 43 covers all sides of the clay sculpture and preventing the local temperature of the clay sculpture from being too high due to the air outlet 43 being too close to the clay sculpture.

[0066] The 3D printing numerical control intelligent ceramic clay sculpture device of the present invention not only improves the efficiency of sculpture creation, but also provides more creative freedom for artists. Artists can easily adjust the shape and details of the sculpture through computer software and accurately transform these designs into physical sculptures through the above device.
