[0037] The present invention will be described in further detail below with reference to the accompanying drawings.

[0038] like Figures 2 to 11 As shown, the structure and function of a porous bioceramic artificial bone preparation system are described in detail below;

[0039] A porous bioceramic artificial bone preparation system includes a device support 11, a swing support 12 is rotatably connected to the device support 11, and a power mechanism I is fixedly connected to the device support 11 to drive the swing support 12 to rotate, and the power mechanism I is preferably a servo motor;

[0040] A storage cavity 21 is fixedly connected to the swing bracket 12, and support cylinders 22 are fixedly connected to both sides of the storage cavity 21. The interiors of the two support cylinders 22 are inclined, and the outer sides of the two support cylinders 22 are fixedly connected to connection disks 24. The two connection disks 24 are rotatably connected to the rotating ring I 25. The lower end of the storage cavity 21 is fixedly connected to the discharge cavity 23.

[0041] A rotating cylinder 31 is slidably connected to each of the two rotating rings I 25, and a rotating disk 32 is rotatably connected to each of the two rotating cylinders 31. The two rotating disks 32 are rotatably connected to the two supporting cylinders 22 respectively. A kneading cylinder 33 is fixedly connected between the two rotating cylinders 31. The kneading cylinder 33 is provided with multiple holes, and multiple rubber balls are placed in the kneading cylinder 33.

[0042] The two rotating cylinders 31 are rotatably connected to a pulling ring 34, and the pulling ring 34 is fixedly connected to a power mechanism II for driving the rotating cylinder 31 to rotate. The power mechanism II is preferably a servo motor. The two pulling rings 34 are respectively fixedly connected to the telescopic ends of the two telescopic mechanisms I 35, and the two telescopic mechanisms I 35 are fixedly connected to the swing bracket 12.

[0043] The kneading cylinder 33 is made of elastic material;

[0044] During use, the artificial bone after 3D laser sintering printing is placed in the kneading cylinder 33, the closing cover 60 is opened, and the artificial bone is placed in the kneading cylinder 33 from the rotating cylinder 31 on one side of the closing cover 60. A plurality of rubber balls are placed in the kneading cylinder 33 in advance, and the power mechanism II is started. The output shaft of the power mechanism II starts to rotate, and the output shaft of the power mechanism II drives the rotating cylinder 31 to rotate, and the rotating cylinder 31 drives the kneading cylinder 33 to rotate, and the kneading cylinder 33 drives the plurality of rubber balls and the artificial bone therein to rotate, and the plurality of rubber balls perform a throwing motion in the kneading cylinder 33, that is, the plurality of rubber balls follow the kneading cylinder 33 to rotate to a certain height and then fall, thereby knocking the artificial bone, causing the powder on the artificial bone to fall off;

[0045] Furthermore, in order to increase the relative movement between the artificial bone and the multiple rubber balls, that is, to increase the friction of the multiple rubber balls on the artificial bone, the telescopic mechanism I35 is started. The telescopic mechanism I35 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I35 drives the corresponding pulling ring 34 to move, and the pulling ring 34 drives the rotating cylinder 31 to move. The two rotating cylinders 31 move closer to or away from each other, and then the two rotating cylinders 31 squeeze the kneading cylinder 33. The kneading cylinder 33 is made of elastic material and is deformed. Then, during the rotation process, the kneading cylinder 33 squeezes and kneads the artificial bone and the multiple rubber balls, thereby increasing the relative movement between the artificial bone and the multiple rubber balls, so that the powder on the artificial bone falls off quickly.

[0046] Furthermore, the power mechanism I can be started, and the output shaft of the power mechanism I rotates, and the output shaft of the power mechanism I drives the swing bracket 12 to move, so that the swing bracket 12 swings, and the swing bracket 12 drives the supporting cylinder 22 to swing, and the supporting cylinder 22 drives the rotating cylinder 31 to swing, and the rotating cylinder 31 drives the kneading cylinder 33 to swing, so that the powder on the artificial bone falls off quickly. When the artificial bone is taken out, the power mechanism I can also be started to make the kneading cylinder 33 tilt to a certain extent, thereby facilitating the removal of the artificial bone in the kneading cylinder 33.

[0047] Furthermore, a buckling disk 41 is rotatably connected to the pulling ring 34 on one side, and a closing cover 60 is buckled on the pulling ring 34 on the other side. A power mechanism III for driving the buckling disk 41 to rotate is fixedly connected to the pulling ring 34. The power mechanism III is preferably a servo motor. The buckling disk 41 is fixedly connected to the wind pipe 42, and the wind pipe 42 is fixedly connected to the rotating seat 43. The rotating seat 43 is fixedly connected to the telescopic mechanism II 44. The telescopic end of the telescopic mechanism II 44 is fixedly connected to the air dispersion duct 45. The air dispersion duct 45 is provided with a plurality of air dispersion holes. The air dispersion duct 45 is connected to the wind pipe 42 and is located in the kneading cylinder 33.

[0048] When in use, place the scattered air duct 45 in the kneading cylinder 33, connect the wind duct 42 to a wind device, such as an air pump, in advance, and continuously pass wind into the wind duct 42 through the wind device. The wind duct 42 and the scattered air duct 45 are connected, and then the wind continuously passes from the wind duct 42 to the scattered air duct 45. Figure 9 As shown, the air dispersing duct 45 is provided with a plurality of air dispersing holes, which disperse the wind into the kneading cylinder 33, and the artificial bone is impacted by the wind from the inside of the kneading cylinder 33. That is, the artificial bone is continuously impacted by the wind during the movement, causing the powder on the artificial bone to fall off;

[0049] Furthermore, the position of the air duct 45 can be adjusted according to the position and height of the rubber ball parabolic object, and the power mechanism III is started, and the output shaft of the power mechanism III starts to rotate, and the output shaft of the power mechanism III drives the buckle plate 41 to rotate, and the buckle plate 41 drives the wind duct 42 to rotate, and the wind duct 42 drives the rotating seat 43 to rotate, and the rotating seat 43 drives the telescopic mechanism II 44 to move, and the telescopic mechanism II 44 drives the air duct 45 to move, thereby adjusting the position of the air duct 45, and starting the telescopic mechanism II 44. The telescopic mechanism II 44 can be a hydraulic cylinder or an electric push rod, and the telescopic end of the telescopic mechanism II 44 drives the air duct 45 to move, thereby adjusting the position of the air duct 45, and adjusting the relative position of the air duct 45 and the moving artificial bone, thereby meeting different processing requirements;

[0050] Furthermore, since the air dispersion duct 45 applies wind force to the artificial bone from the inside of the kneading cylinder 33, the wind force attenuation is reduced compared to that from the outside of the kneading cylinder 33, and the powder blown down moves from the inside of the kneading cylinder 33 to the outside, that is, from the inside of the kneading cylinder 33 through the multiple holes into the support cylinder 22, and is discharged from the discharge cavity 23. The discharged powder can be collected from the discharge cavity 23 and can be reused.

[0051] Furthermore, in order to reduce the powder residue in the receiving cavity 21 and the supporting cylinder 22, reduce the powder residue on the kneading cylinder 33, and also to further enhance the deformation that the kneading cylinder 33 can produce;

[0052] A rotating ring II 51 is rotatably connected between the two support cylinders 22 and the two connecting disks 24. A power mechanism IV for driving the rotating ring II 51 to rotate is fixedly connected to the connecting disk 24. The power mechanism IV is preferably a servo motor. A plurality of knocking shafts 52 are rotatably connected between the two rotating rings II 51. The plurality of knocking shafts 52 are rotatably connected to the two rotating disks 32 respectively. A power mechanism V for driving the knocking shafts 52 to rotate is fixedly connected to the rotating ring II 51. The power mechanism V is preferably a servo motor.

[0053] Each beating shaft 52 is fixedly connected to a beating cylinder 53, and each beating shaft 52 is slidably connected to a plurality of beating posts 54, the beating posts 54 are in contact with the beating cylinder 53, and the beating cylinder 53 is located outside the kneading cylinder 33, and the beating cylinder 53 is made of elastic material;

[0054] When in use, the power mechanism IV is started, the output shaft of the power mechanism IV starts to rotate, the output shaft of the power mechanism IV drives the rotating ring II 51 to rotate, the rotating ring II 51 drives the multiple knocking shafts 52 to revolve, the power mechanism V is started, the output shaft of the power mechanism V starts to rotate, the output shaft of the power mechanism V drives the knocking shaft 52 to rotate, the knocking shaft 52 drives the multiple knocking columns 54 to rotate, the multiple knocking columns 54 squeeze the knocking cylinder 53 under the action of centrifugal force, so that the knocking cylinder 53 is rotated. 3 produces deformation, the beating cylinder 53 squeezes the kneading cylinder 33 in contact, causing the kneading cylinder 33 to produce deformation, and at the same time, driven by the rotating ring II 51, multiple beating cylinders 53 continuously rotate around the kneading cylinder 33, causing the kneading cylinder 33 to produce different deformations, thereby increasing the squeezing of the kneading cylinder 33 on the rubber ball and the artificial bone, and at the same time knocking off the powder on the kneading cylinder 33, so that there will be no residual powder on the kneading cylinder 33, so that the powder in the kneading cylinder 33 can be discharged from the discharge cavity 23;

[0055] Furthermore, since the beating cylinder 53 seals the multiple beating columns 54 to prevent powder from entering between the multiple beating columns 54, the beating cylinder 53 is cylindrical in shape. In order to ensure that no powder will remain on the beating cylinder 53, the power mechanism IV is started, and the output shaft of the power mechanism IV starts to rotate. The output shaft of the power mechanism IV drives the rotating ring II 51 to rotate, and the rotating ring II 51 drives the multiple beating shafts 52 to revolve, so that the multiple beating cylinders 53 rotate. At the same time, the power mechanism V is started, and the output shaft of the power mechanism V starts to rotate. The output shaft of the power mechanism V drives the beating shaft 52 to rotate, and the beating shaft 52 drives the multiple beating columns 54 to rotate. Under the action of centrifugal force, the multiple beating columns 54 squeeze the beating cylinder 53, so that the beating cylinder 53 is deformed, and the powder that may remain on the beating cylinder 53 is knocked off, thereby minimizing the residual powder as much as possible. By collecting the powder, it can be used next time, thereby improving the utilization rate.
