Description

Technical Field

[0001] The present application relates to the technical field of 3D printers, and in particular to an auxiliary cleaning device for a denture model 3D printer. Background Art

[0002] 3D printing is a type of rapid prototyping technology. It is a technology that uses digital model files as the basis, uses powdered metal or plastic and other adhesive materials to construct objects by printing layer by layer. 3D printing technology is widely used in the denture manufacturing industry. The human mouth is scanned by a scanner, and a 3D dental mold is obtained through precise calculations by computer software, which is then printed out using 3D printing technology.

[0003] A 3D printer for printing denture models mentioned in an existing Chinese public patent (authorization announcement number: CN215550969U) relates to the field of 3D printers. The 3D printer for printing denture models has a printing box, a groove is provided on the front of the printing box, and the front end of the groove provided on the front of the printing box is connected to a box door by a hinge. The 3D printer for printing denture models, by setting the positional relationship between the support plate, the sliding groove bottom plate, the rear sliding wheel and the limit plate, allows the bottom plate to move forward through the rear sliding wheel and the rear sliding wheel, which is convenient for the user to tape the bottom plate from the front end of the printing box. By setting the connection relationship between the moving block, the arc plate, the rotating gear, the rotating column and the bottom plate, the moving block is driven to move upward by rotating the rotating column, so that the moving block pulls the tape upward, which is convenient for tearing off the tape and taking out the model.

[0004] The above patent drives the moving block to move upward by rotating the rotating column, so that the moving block pulls the tape upward, which is convenient for tearing off the tape and taking out the model. However, after the printer finishes printing, the temperature of the nozzle will gradually decrease, so that some of the printing materials remaining on the nozzle will gradually solidify on the nozzle. If these materials are not cleaned up in time, the quality of the next print will be affected. To clean these solidified materials, it is usually necessary to remove the nozzle and use a brush to clean it, which is inconvenient. For this reason, the present application provides an auxiliary cleaning device for a denture model 3D printer. Utility Model Content

[0033] The embodiment of the present application discloses a denture model 3D printer auxiliary cleaning device.

[0035] When in use, first set the shape of the denture model to be printed through the control console 1, then start the nozzle 6 to start printing the denture model on the printing table 7 according to the shape set by the system. After the denture model is printed, the nozzle 6 can be turned off and wait for the nozzle 6 to gradually cool down. At this time, the adjustment component 8 can be started according to the position of the nozzle 6 to drive the support plate 9 to move, so that the cleaning component 12 on the support plate 9 moves to the bottom of the nozzle 6, and then the cleaning component 12 is operated to open and move the nozzle 6 into the cleaning component 12, and then the nozzle 6 is wrapped by the cleaning component 12. At this time, start the motor 10 to drive the turntable 11 to rotate, and the rotation of the turntable 11 makes the cleaning component 12 rotate together. The rotating cleaning component 12 can clean the material on the surface of the internal nozzle 6 in all directions without the need to remove the nozzle 6 for wiping, which greatly improves the cleaning efficiency and saves cleaning time.

[0036] Reference Figure 1 and Figure 2 The adjustment component 8 includes a fixing frame 81 fixedly connected to the top of the console 1, a threaded rod 82 is rotatably connected inside the fixing frame 81, a motor 2 83 is fixedly connected to one end of the fixing frame 81, an output end of the motor 2 83 is fixedly connected to one end of the threaded rod 82, a connecting block 84 is threadedly connected to the threaded rod 82, a guide rod 85 is fixedly connected inside the fixing frame 81, one end of the connecting block 84 away from the threaded rod 82 is slidably connected to the guide rod 85, and the top of the connecting block 84 is fixedly connected to the bottom of the support plate 9.

[0037] When in use, first start the motor 2 83 to drive the threaded rod 82 to rotate. Through the continuous rotation of the threaded rod 82, the connecting block 84 can be moved inside the fixed frame 81 under the guidance of the guide rod 85, so that the support plate 9 moves with the connecting block 84. By adjusting the position of the support plate 9, the support plate 9 can be moved to the bottom of the nozzle 6, which makes it more convenient to clean the nozzle 6.

[0038] Reference Figure 1 and Figure 2The cleaning assembly 12 includes a slide rail 121 fixedly connected to the top of the turntable 11, and two sliders 122 are symmetrically slidably connected to the slide rail 121, and a fixed block 123 is fixedly connected to the slide rail 121. The two sliders 122 are located on both sides of the fixed block 123, and one side of the fixed block 123 is rotatably connected to an adjusting handle 124, and the side of the fixed block 123 away from the adjusting handle 124 is rotatably connected to a rotating block 125, and the rotating block 125 is in the shape of a rectangular parallelepiped, and the tops of the two sliders 122 are fixedly connected to a fixed plate 126, and one side of the fixed plate 126 is fixedly connected to a hook 127, and a tension spring 128 is fixedly connected between the two hooks 127, and the end of the fixed plate 126 away from the hook 127 is fixedly connected to a clamping plate 129, and an arc groove is provided on the corresponding surface of the clamping plate 129, and the size of the arc groove is adapted to the nozzle 6, and a brush 1291 is fixedly connected inside the arc groove.

[0039] When in use, first turn the adjusting handle 124, and the rotating block 125 is driven to rotate by the rotation of the adjusting handle 124. Because the rotating block 125 is in the shape of a rectangular parallelepiped, when the rotating block 125 rotates, it will squeeze the sliders 122 on both sides to slide on the slide rail 121 and move away from each other. When the two sliders 122 gradually move away from each other, the two fixing plates 126 and the clamping plate 129 on the top will be driven to separate together, so as to open the arc groove, and then move the nozzle 6 to the inside of the two clamping plates 129, and release the adjusting handle 124 again. At this time, according to the rebound contraction of the tension spring 128, the two fixing plates 126 are pulled gradually closer until the arc groove in the two clamping plates 129 completely wraps the nozzle 6, and the nozzle 6 can be cleaned in all directions through the brush 1291 inside the arc groove. The solidified printing material can be easily removed without disassembling the nozzle 6, so as to avoid clogging the nozzle 6 and affecting the next printing.

[0040] The implementation principle of the auxiliary cleaning device for the denture model 3D printer of this embodiment is as follows: when in use, first set the shape of the denture model to be printed through the control console 1, then start the nozzle 6 to start printing the denture model on the printing table 7 according to the shape set by the system, after the denture model is printed, the nozzle 6 can be turned off and wait for the nozzle 6 to gradually cool down, at this time, the motor 2 83 can be started to drive the threaded rod 82 to rotate, and the continuous rotation of the threaded rod 82 can make the connecting block 84 move inside the fixing frame 81 through the guidance of the guide rod 85, so that the support plate 9 moves together with the connecting block 84, and the cleaning assembly 12 on the support plate 9 can be moved to the bottom of the nozzle 6 by adjusting the position of the support plate 9;

[0041] Subsequently, the adjusting handle 124 is operated to rotate, and the rotating block 125 is driven to rotate by rotating the adjusting handle 124. Since the rotating block 125 is in the shape of a rectangular parallelepiped, when the rotating block 125 rotates, the sliders 122 on both sides are squeezed to slide on the slide rail 121 and move away from each other. When the two sliders 122 gradually move away from each other, the two fixing plates 126 and the clamping plates 129 at the top are driven to separate together, so as to open the arc groove, and then the nozzle 6 is moved to the inside of the two clamping plates 129, and the adjusting handle 124 is released again. At the same time, according to the rebound and contraction of the tension spring 128, the two fixing plates 126 are pulled closer together until the arc grooves in the two clamping plates 129 completely wrap the nozzle 6. At this time, the motor 10 is started to drive the turntable 11 to rotate. The rotation of the turntable 11 allows the brush 1291 inside the arc groove to clean the nozzle 6 in all directions. In this way, the solidified printing material can be easily removed without disassembling the nozzle 6, avoiding clogging of the nozzle 6 and affecting the next printing, thereby greatly improving the cleaning efficiency of the device and saving cleaning time.
