[0001] The utility model relates to the technical field of 3D printers, in particular to a medical 3D printer. Background Art
[0002] A 3D printer is a device that can print products in three dimensions. By establishing a digital model, it can build the printed object layer by layer. It can print the precise model required by the patient, effectively reducing the required production cycle and lowering costs.
[0003] A medical 3D printer includes a printing assembly and a base plate. When in use, printing can be performed on the base plate by moving the printing assembly. For example, a dentist can print the required mold on the base plate. To ensure stability during the printing process, the base plate needs to be stably fixed under the printing assembly during printing. After printing is completed, the staff needs to remove the base plate and replace it with a new one. Since the base plate inside the printer cannot be alternately fixed and replaced, the manual operation time is increased during printing. When a large number of products need to be printed, the production efficiency is low. In order to solve this technical problem, the present utility model proposes a medical 3D printer.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1-5 As shown, a medical 3D printer includes a support base 1, a protective shell 2 is fixedly installed above the support base 1, a controller 14 is installed on the outside of the support base 1, a rotating frame is installed at the bottom of the controller 14, and the position of the controller 14 can be adjusted by the rotating frame, and a printing component 3 is installed inside the protective shell 2. The printing component 3 can print above the base plate 10 under the control of the controller 14.
[0024] A support plate 4 is fixedly installed inside the support seat 1, and a fixed shaft 5 is rotatably connected inside the support plate 4. A motor 15 is fixedly installed on the lower surface of the support plate 4. The output end of the motor 15 is connected to the other end of the fixed shaft 5. The fixed shaft 5 can be driven to rotate by the motor 15. A rotating plate 6 is fixedly installed at one end of the fixed shaft 5. The position of the rotating plate 6 can be controlled by the cooperation of the motor 15 and the fixed shaft 5.
[0025] A positioning hole 7 is provided inside the rotating plate 6, and a positioning rod 8 is slidably connected to the inside of the positioning hole 7. A base plate 10 is fixedly installed on the upper surface of the positioning rod 8. The upper and lower positions of the base plate 10 can be controlled by cooperating with the positioning hole 7 and the positioning rod 8. When installing the base plate 10, the positioning rod 8 can be directly inserted into the inside of the positioning hole 7. Multiple groups of support rings 19 are fixedly installed on the upper surface of the rotating plate 6. The upper surface of the support ring 19 contacts the lower surface of the base plate 10. The support ring 19 can separate the base plate 10 from the rotating plate 6, which is convenient for the staff to take out.
[0026] A support plate 2 11 is fixedly installed inside the support seat 1, and multiple sets of auxiliary wheels 16 are fixedly installed on the upper surface of the support plate 14. Multiple sets of auxiliary wheels 2 17 are fixedly installed on the upper surface of the support plate 2 11. The outer surfaces of the auxiliary wheels 16 and 17 are in contact with the lower surface of the rotating plate 6. The support plate 1 4 and the support plate 2 11 can provide auxiliary support for the rotating plate 6. The outside of the auxiliary wheels 16 and 17 are equipped with multiple sets of rolling wheels, which can assist the rotating plate 6 in rotating and ensure the stability of the rotating plate 6 during rotation.
[0027] A partition 18 is fixedly installed on the upper surface of the rotating plate 6. The partition 18 is located at the center of the rotating plate 6. The two sets of base plates 10 can be separated by the partition 18. When the medical staff takes out the dental mold after printing, the partition 18 can separate the outside of the rotating plate 6, which can protect the medical staff and prevent them from being injured during printing.
[0028] A slot 9 is provided inside the positioning rod 8 , and a slot 9 with the same direction is provided on one side of the positioning rod 8 . The inside of the slot 9 has a slope inclined upward.
[0029] A fixed box 12 is fixedly installed on the lower surface of the support plate 2 11, and a movable plate 13 is slidably connected inside the fixed box 12. One end of the movable plate 13 is a wedge-shaped structure, and the outer surface of the movable plate 13 is slidably connected to the inside of the card slot 9. After the movable plate 13 enters the inside of the card slot 9, it can fix the upper and lower positions of the positioning rod 8. At this time, the bottom plate 10 cannot move in the up and down directions.
[0030] Multiple sets of limit plates 20 are fixedly installed on both sides of the movable plate 13, and a limit groove 21 is opened inside the fixed box 12. The outer surfaces of the multiple sets of limit plates 20 are slidably connected to the inside of the limit groove 21. The position of the movable plate 13 can be limited by the cooperation of the limit groove 21 and the limit plate 20 to prevent the movable plate 13 from losing contact with the fixed box 12.
[0031] The inner wall of the fixed box 12 is fixedly installed with multiple groups of connecting rods 22. The outer surface of the connecting rod 22 is slidably connected to the inside of the movable plate 13. A through hole is opened inside the movable plate 13 to facilitate the insertion of the connecting rod 22. A spring 23 is sleeved on the outside of the connecting rod 22. One end of the spring 23 contacts the inner wall of the fixed box 12, and the other end of the spring 23 is connected to one side of the movable plate 13. The spring 23 can push the movable plate 13 to move elastically. When the positioning rod 8 rotates, it can squeeze the movable plate 13. At this time, the movable plate 13 will move toward the inside of the fixed box 12. When the slot 9 is aligned with the slope of the movable plate 13, the spring 23 pushes the movable plate 13 into the inside of the slot 9. Similarly, when the rotating plate 6 rotates, the movable plate 13 will automatically release the fixation of the positioning rod 8, which is convenient for the staff to take out after the mold printing is completed.
[0032] The two groups of base plates 10 that are set can perform alternating printing. The rotating plate 6 can drive the base plate 10 to rotate. When installing the base plate 10, the positioning rod 8 is inserted through the positioning hole 7, and the rotating plate 6 drives the positioning rod 8 to rotate to the position of the movable plate 13. When the positioning rod 8 contacts the movable plate 13, the movable plate 13 will move toward the inside of the fixed box 12. When the slot 9 is aligned with the slope of the movable plate 13, the spring 23 will push the movable plate 13 to move and enter the inside of the slot 9. At this time, the movable plate 13 can limit the upper and lower positions of the positioning rod 8. After one group of base plates 10 is printed, the rotating plate 6 is controlled to rotate by the motor 15. At this time, the rotating plate 6 can drive the positioning rod 8 to rotate. The elastic movement of the movable plate 13 can automatically release the limit on the positioning rod 8, and the base plate 10 can be taken out.
