[0028] In order to help those skilled in the art better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] like Figures 1-6 As shown, an embodiment of the present invention provides a 3D printing platform for porous ceramic production, including a frame 1 and a silo 2 arranged on the frame 1 and a printing unit 3 arranged inside the frame 1, the printing unit 3 includes a print head 31 and a position adjustment mechanism 32 connected to the print head 31 and used to adjust the position of the print head 31, the print head 31 is connected to the silo 2 through a pipe 4, and a heat dissipation unit 5 is provided on the side of the frame 1.

[0030] In this embodiment, the position adjustment mechanism 32 includes a horizontal displacement module 321 disposed on the top of the frame 1 and a vertical displacement module 322 disposed on the bottom of the frame 1 . The print head 31 is disposed below the horizontal displacement module 321 .

[0031] In this embodiment, the horizontal plane displacement module 321 includes a sliding mechanism 3211, a motor 3212, a threaded rod 3213, a threaded block 3214 and a connecting frame 3215. The motor 3212 is fixedly connected to the sliding mechanism 3211. The motor 3212 is arranged at one end of the threaded rod 3213. The threaded block 3214 is sleeved on the outer surface thread of the threaded rod 3213. A limiting plate 3216 is fixedly installed on one side of the sliding mechanism 3211. The connecting frame 3215 is fixedly installed on the bottom of the threaded block 3214. The bottom of the connecting frame 3215 passes through the upper and lower sides of the limiting plate 3216 and is fixedly installed with a connecting block 3217. The print head 31 is installed at the lower end of the connecting block 3217.

[0032] In this embodiment, the connecting frame 3215 is provided with a rolling shaft 3218 and a rolling wheel 3219 at the connecting position of the connecting frame 3215 and the threaded block 3214. The rolling shaft 3218 penetrates through the opposite two side surfaces of the connecting frame 3215, and the rolling wheel 3219 is movably sleeved on the outer surface of the rolling shaft 3218. Through the design of the rolling shaft 3218 and the rolling wheel 3219, the sliding friction between the threaded block 3214 and the limiting plate 3216 is converted into rolling friction, thereby reducing the friction.

[0033] When the staff uses it, the staff starts the 3D printing platform for porous ceramic production, and the 3D printing platform for porous ceramic production starts to start the motor one 3212 through the controller. When the motor one 3212 starts, it will drive the rotation of the threaded rod 3213. When the threaded rod 3213 rotates, the threaded block 3214 and the threaded rod 3212 are connected. Since the threaded block 3214 and the threaded rod 3212 are connected, the threaded block 3214 will be moved with the rotation of the threaded rod 3212. When the threaded block 3214 moves, it will drive the connecting frame 3215 to move, and the movement of the connecting frame 3215 will drive the connecting block 3217 to move, so that the rolling wheel 3219 rolls above the limiting plate 3216. Compared with the traditional device, the 3D printing platform for porous ceramic production can move the print head 31 above the vertical plane displacement module 322 to any position through the movement of the print head, thereby avoiding the cost waste caused by the design of multiple print heads 31. Through the movement of the print head 31, the cost of the 3D printing platform for porous ceramic production can be reduced, and the working efficiency of the 3D printing platform for porous ceramic production is improved.

[0034] In this embodiment, the sliding mechanism 3211 includes an electric slide rod 32111 fixedly arranged on one side of the frame body 1. The outer surface of the electric slide rod 32111 movably sleeves an electric slide block 32112. The upper side of the electric slide block 32112 is fixedly connected with the motor one 3212, and the side surface of the electric slide block 32112 is fixedly connected with the limiting plate 3216. The movement of the electric slide block 32112 is driven by the electric slide rod 32111 started by the controller, and the movement of the motor one 3212 is driven when the electric slide block 32112 moves.

[0035] In this embodiment, the vertical plane displacement module 322 includes an electric telescopic rod 3221 and a telescopic plate 3222. The telescopic plate 3222 is fixedly installed above the electric telescopic rod 3221. The electric telescopic rod 3221 is started to drive the telescopic plate 3222 to rise and fall, which is equivalent to adjusting the height of the print head 31 in the vertical direction, thereby cooperating with the printing of the porous ceramic.

[0036] In this embodiment, the heat dissipation unit 5 includes the second motor 51, the transmission module 52 and the fan blade 53, and the two ends of the transmission module 52 are connected with the second motor 51 and the fan blade 53 respectively. The transmission module 52 can be a combination of a rotating wheel assembly and a belt, the rotating wheel assembly includes two rotating wheels, one of which is arranged on the transmission shaft of the second motor 51, and the other is arranged on a cross-shaped support, and the belt is arranged between the two rotating wheels, and the fan blade 53 is also arranged on the cross-shaped support. The reason for setting the transmission module 52 is that when the 3D printing platform for producing porous ceramics starts to work, the rotation of the fan blade 53 will concentrate the heat generated during printing and dissipate it outward, and at the same time, the second motor 51 will also generate a large amount of heat due to its own work. If the second motor 52 is directly connected with the fan blade 53, the second motor 52 will bear two heat, which will cause the work of the second motor 52 to produce load, increase the heat, and reduce the service life of the second motor 53. The use of the transmission module 52 can greatly improve the service life of the second motor 53.

[0037] In this embodiment, when the staff uses the 3D printing platform for producing porous ceramics to print, the staff first starts the second motor 51 through the controller, and when the second motor 51 starts, it will drive the rotation of the transmission shaft of the second motor 51, and when the transmission shaft rotates, it will drive the rotation of the rotating wheel, and when the rotating wheel rotates, it will drive the rotation of the other rotating wheel through the transmission of the belt, and when the rotating wheel on the cross-shaped support rotates, it will drive the rotation of the fan blade 53, and through the rotation of the fan blade 53, the heat generated during the printing of the device will be quickly exchanged with the cold air outside. Compared with the traditional device, the 3D printing platform for producing porous ceramics of the embodiment can improve the working efficiency of the 3D printing platform for producing porous ceramics by dissipating heat, and can reduce the temperature of the porous ceramics after printing, and improve the cooling speed.

[0038] In this embodiment, the frame body 1 includes a base frame 11, a vertical frame 12 and a top cover 13, and the hopper 2 is arranged above the top cover 13.

[0039] In this embodiment, the upper part of the hopper 2 is movably provided with a plug 6, and the bottom of the plug 6 extends into the interior of the hopper 2. Through the design of the printing head 31, the raw materials in the hopper 2 enter the interior of the printing head 31 through the interior of the pipeline 4, and then are printed on the upper part of the telescopic plate 3222 by the printing head 31 to print the porous ceramics.
