[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the following further details the present utility model in conjunction with the attached Figures 1-13 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] Refer to Figure 1 , Figure 2 and Figure 3, A ceramic clay 3D printer, suitable for printing large-sized product models, includes a frame 1, a material barrel 2, a feeding device 3, a control box 4, a printing platform 5, a print head 6 and a connecting pipe 7. The material barrel 2 and the feeding device 3 are arranged on one side of the frame 1, with the material barrel 2 placed above the feeding device 3. The feeding device 3 includes a feeding cylinder 31 and a piston 32. The feeding cylinder 31 is vertically upward and penetrates into the material barrel 2, and the piston 32 is fixed at the top of the feeding cylinder 31 and horizontally clamped in the material barrel 2. On one side of the print head 6, there is a feeding head 61. The two ends of the connecting pipe 7 are respectively connected to the material barrel 2 and the feeding head 61. A large amount of ceramic clay is contained in the material barrel 2. The telescopic rod of the feeding cylinder 31 extends to extrude the ceramic clay through the piston 32. The ceramic clay enters the print head 6 through the connecting pipe 7 and is printed out in the print head 6.

[0033] Refer to Figure 4 and Figure 5 , On the frame 1, a moving frame 11 is horizontally and longitudinally slidably arranged. Thus, a horizontal longitudinal sliding assembly 8 is arranged between the moving frame 11 and the frame 1. The horizontal longitudinal sliding assembly 8 includes a power assembly 81, a rotating rod 82, a first synchronous pulley 83, a second synchronous pulley 84, a first synchronous belt 85, two longitudinal sliding tracks 86 and several longitudinal sliding seats 87. The two longitudinal sliding tracks 86 are horizontally and longitudinally arranged on both sides of the frame 1. Several longitudinal sliding seats 87 are fixedly arranged on both sides of the bottom end of the moving frame 11, and several longitudinal sliding seats 87 are respectively seated on the longitudinal sliding tracks 86. The rotating rod 82 is horizontally rotatably arranged on the frame 1. The first synchronous pulleys 83 are fixedly arranged at both ends of the rotating rod 82. The second synchronous pulley 84 is rotatably installed on the frame 1. The first synchronous belt 85 is wound around the peripheries of the first synchronous pulley 83 and the second synchronous pulley 84, and the moving frame 11 is fixed to the first synchronous belt 85.

[0034] And the power assembly 81 is set as a power motor, and a driving wheel 811 is fixedly arranged on the rotating shaft of the power motor. A driven wheel 821 is fixedly arranged at one end of the rotating rod 82. A second synchronous belt 88 is wound around the peripheries of the driving wheel 811 and the driven wheel 821. The rotating shaft of the power motor rotates through the synchronous belt to drive the rotating rod 82 to rotate. The rotating rod 82 rotates through the first synchronous belt 85 to drive the moving frame 11 to perform a longitudinal sliding movement.

[0035] Refer to Figure 6 and Figure 7, a moving plate 12 is horizontally and laterally slidably arranged on the moving frame 11, the print head 6 is arranged on the moving plate 12, and a horizontal and lateral sliding assembly 9 is arranged between the moving frame 11 and the moving plate 12. The horizontal and lateral sliding assembly 9 includes a lateral sliding track 91, a lateral sliding seat 92, a driving motor 93, a third synchronous belt 94, a third synchronous pulley 95 and a fourth synchronous pulley 96. The lateral sliding track 91 is horizontally and laterally fixedly arranged on the moving plate 12, the lateral sliding seat 92 is fixedly arranged at the bottom end of the moving plate 12, and the lateral sliding seat 92 is seated on the lateral sliding track 91. The driving motor 93 is fixedly arranged at the bottom end of the moving frame 11, the third synchronous pulley 95 is fixedly arranged on the rotating shaft of the driving motor 93, the fourth synchronous pulley 96 is rotatably arranged at the bottom end of the moving frame 11, the third synchronous belt 94 is wound around the third synchronous pulley 95 and the fourth synchronous pulley 96, and the sliding plate is fixed to the third synchronous belt 94. The rotation of the rotating shaft of the driving motor 93 drives the moving plate 12 and the print head 6 to perform horizontal and lateral sliding movements through the third synchronous belt 94.

[0036] Refer to Figure 6 , Figure 8 and Figure 9 , a through hole 121 is formed by opening on the surface of the moving plate 12, a bearing 122 is arranged on the moving plate 12, a discharge head 62 is formed at the bottom end of the print head 6, and the print head 6 is installed between the bearing 122, so that a rotational connection is realized between the print head 6 and the moving plate 12, and the discharge head 62 at the bottom end of the print head 6 passes through the through hole 121 on the surface of the moving plate 12. The clay extruded from the print head 6 is formed on the printing platform 5. Under the action of the horizontal and lateral sliding assembly 9 and the horizontal and longitudinal sliding assembly 8, the position of the moving frame 11 is moved. At this time, the print head 6 can adjust the angle with the sliding plate to avoid the phenomenon of the connecting pipe 7 being bent, which not only makes the clay feeding in the connecting pipe 7 smooth, but also can ensure that the connecting pipe 7 has a longer service life.

[0037] Refer to Figure 2 , Figure 10 and Figure 11, the printing platform 5 is located at the bottom end of the print head 6, and a lifting and sliding assembly 51 is provided at the bottom end of the printing platform 5. The printing platform 5 can be driven by the lifting and sliding assembly 51 to achieve lifting and sliding adjustment within the frame 1. The clay extruded by the print head 6 is placed on the printing platform 5, and the lifting and sliding assembly 51 drives the printing platform 5 to lift and slide to adjust the distance between the printing platform 5 and the print head 6, so that the print head 6 is adapted to the position where the product is printed. As the print head 6 moves to drive the connecting pipe 7 to move, in order to ensure the smooth movement of the connecting pipe 7, a pair of abutting rods 16 are horizontally and transversely arranged on the frame 1. A certain distance is maintained between the two abutting rods 16 and they are on the same vertical plane, so that the connecting pipe 7 is arranged between the two abutting rods 16, thereby preventing the connecting pipe 7 from contacting the surface of the frame 1, reducing the contact between the connecting pipe 7 and the abutting rods 16, and reducing the friction force received by the connecting pipe 7 during the movement process.

[0038] Referring to Figure 1 , Figure 12 and Figure 13 , and a baffle 14 is provided on the periphery of the frame 1. A long strip-shaped through groove 141 for the connecting pipe 7 to pass through is opened on the baffle 14. The abutting rods 16 are arranged above and below the long strip-shaped through groove 141. During the process of the connecting pipe 7 moving along with the print head, it is exactly located within the long strip-shaped through groove 141 and is arranged between the two abutting rods 16.

[0039] A heater 13 is provided at the bottom end within the frame 1. The heater 13 is enclosed by the baffle 14, and a cover plate 15 is provided at the top end of the frame 1. The cover plate 15 is rotatably connected to one side of the top end of the frame 1. The cover plate 15 is covered on the top end of the frame 1, so that the cover plate 15 and each baffle 14 enclose each other to form a closed space. The heater 13 blows out hot air to evaporate the moisture in the clay, thereby improving the forming speed of the product. The formed closed space can reduce heat loss. And the control box 4 is fixedly arranged on one side outside the frame 1, thereby preventing the heater 13 from being damaged due to the too high temperature in the closed space. In order to facilitate understanding the printing and forming progress of the product in the closed space, a notch 151 is formed on the surface of the cover plate 15, and a viewing window 152 is installed in the notch 151. The interior of the closed space can be observed through the viewing window 152.

[0040] The specific implementation principle of the embodiment of this application is: when it is necessary to use this kind of clay 3D printer to print a product, the telescopic rod of the feeding cylinder 31 extends to drive the piston 32 to extrude the clay into the connecting pipe 7, and enter the print head 6 from the connecting pipe 7. The print head 6 extrudes the clay onto the printing platform 5.

[0041] According to the position required to be printed on the product, the rotation of the rotating shaft of the power motor drives the rotating rod 82 to rotate through the synchronous belt. The rotation of the rotating rod 82 drives the moving frame 11 to perform a longitudinal sliding movement through the first synchronous belt 85, so as to adjust the horizontal and longitudinal position of the print head 6. The rotation of the rotating shaft of the driving motor 93 drives the third synchronous belt 94 to be transmitted through the third synchronous pulley 95. The transmission of the third synchronous belt 94 drives the moving plate 12 and the print head 6 to perform a horizontal transverse sliding movement, so as to adjust the horizontal transverse position of the print head 6. And the printing platform 5 performs a lifting and sliding movement on the frame 1, so as to keep a proper distance between the printing platform 5 and the print head 6, so that the position of the product to be printed is adapted to the print head 6. While the product is being 3D printed, the heater 13 starts to work to blow out hot air, and the hot air is used to accelerate the evaporation of the water in the clay, so that the product is quickly formed.

[0042] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
