Description

Technical Field

[0002] Zirconia is the main oxide of zirconium. Under normal conditions, it is a white, odorless, and tasteless crystal, and is sparingly soluble in water, hydrochloric acid, and dilute sulfuric acid. It is chemically inert and possesses properties such as a high melting point, high resistivity, high refractive index, and low coefficient of thermal expansion, making it the primary raw material for all-ceramic crowns.

[0003] In actual production, denture raw materials need to be initially processed into powder cakes for further processing. Various powders of the raw materials need to be pressed together in a certain proportion, and each layer needs to be flattened and pressed together during the pressing process. Existing technology generally involves pressing one raw material and then pressing another raw material together. The method of pressing one material at a time results in low pressing efficiency of the powder cakes, making it difficult to carry out mass production.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Reference Figure 1-11 A powder press with automatic loading and unloading function includes a drive motor 1 and a worktable 2. The bottom end of the drive motor 1 is connected to a base 3. The top end of the base 3 is fixedly connected to a material changing motor 4 via a fixing plate. The output end of the material changing motor 4 is connected to a material changing plate 6 via a rotating shaft 5. The bottom end of the material changing plate 6 is connected to multiple electric push rods 7. Each of the multiple electric push rods 7 is provided with a storage box 11. The moving end of the electric push rod 7 is connected to an adjustment component. The bottom of the adjustment component is provided with a discharge cylinder 13. The outer wall of the bottom end of the discharge cylinder 13 is connected to a flattening and compacting plate 15.

[0035] Furthermore, the bottom end of the drive motor 1 is fixedly connected to the top end of the base 3, and the output end of the drive motor 1 is fixedly connected to the bottom end of the worktable 2 via a drive shaft. The output end of the material changing motor 4 is fixedly connected to the top end of the material changing plate 6 via a rotating shaft 5. The bottom end of the material changing plate 6 is fixedly connected to the fixed ends of multiple electric push rods 7. The adjustment assembly consists of an adjustment rod 8 and a sliding knob 10. The moving end of the electric push rod 7 is fixedly connected to the top end of the adjustment rod 8. A threaded groove is provided on the outer wall of the adjustment rod 8, and the inner wall of the threaded groove is slidably connected to the side wall of the sliding knob 10. A sealing plate 9 is fixedly connected to the top end of the storage box 11, and the inner wall of the sealing plate 9 is fixedly connected to the side wall of the sliding knob 10. The bottom end of the adjustment rod 8 is fixedly connected to... Multiple adapter rods 12 are connected to the top of the discharge cylinder 13. An extension tube 14 is slidably connected to the outer wall of the discharge cylinder 13. The top of the extension tube 14 is fixedly connected to the bottom of the storage box 11. Multiple discharge holes are opened on the outer wall of the discharge cylinder 13. The bottom outer wall of the discharge cylinder 13 is rotatably connected to one end of the flattening and compacting plate 15. A pin 41 is fixedly connected to the inner end of the flattening and compacting plate 15. A bevel gear 40 is fixedly connected to the outer wall of the pin 41. An adjusting gear 39 is meshed with the bevel gear 40. An adjusting motor 38 is fixedly connected to the shaft of the adjusting gear 39 through an adjusting shaft. The adjusting motor 38 is located inside the bottom of the discharge cylinder 13.

[0036] It should be noted that: Starting the drive motor 1 uses the drive shaft to drive the worktable 2 to rotate intermittently. The worktable 2 rotates a template 16 to directly below the material changing motor 4, which is the feeding end. Starting the material changing motor 4 uses the rotating shaft 5 to drive the material changing plate 6 to rotate intermittently. The material changing plate 6 drives a storage box 11 to rotate above the template 16. Then, the electric push rod 7 is pushed down a predetermined distance. The electric push rod 7 drives the adjusting rod 8 to move down. The adjusting rod 8 rotates by sliding between its threaded groove and the sliding knob 10, thereby allowing the adjusting rod 8 to drive the discharge cylinder 13 to rotate and move down via the adapter rod 12. The downward rotation of the discharge cylinder 13 will release the raw material powder inside. The powder is gradually sprinkled out through the discharge hole. At the same time, the rotating multiple adapter rods 12 will stir the powder in the storage box 11 into the extension tube 14 and into the discharge cylinder 13. When moving downward, the adjusting motor 38 drives the adjusting gear 39 to rotate at a certain angle, and drives multiple bevel gears 40 to rotate. Thus, the pin shaft 41 causes the flattening and compacting plate 15 to deflect at a certain angle, so that the lower side of the inclined flattening and compacting plate 15 remains flat, and the sprinkled raw material is rotated and flattened. After the raw material is flattened to the specified height, the multiple flattening and compacting plates 15 are controlled to return to the combined circular plate shape. Then, the electric push rod 7 is used to press down slightly to initially compact the raw material.

[0037] The further advantage of adopting the above is that multiple raw materials can be combined in layers, and the flattening and compacting plate 15 at the bottom of the feeding discharge cylinder 13 can be used to flatten and initially compact the put-in raw materials, thereby improving the speed of layered feeding.

[0038] Example 2

[0039] refer to Figure 1-11 Three templates 16 are set above the workbench 2. The bottom of the template 16 is connected to a toothed ring 17. The bottom of the toothed ring 17 is connected to a connecting ring 19. A threaded push rod 20 is set inside the connecting ring 19. A feeding rack 22 and a feeding rack 23 are respectively set above the workbench 2.

[0040] Furthermore, the top of the workbench 2 is fixedly connected to the outer wall of the template 16 via a fixing rod 18, the bottom of the template 16 is rotatably connected to the top of the toothed ring 17, the bottom of the toothed ring 17 is fixedly connected to the top of the connecting ring 19, the bottom of the connecting ring 19 is provided with a threaded hole, the inner wall of the threaded hole is threadedly connected to the outer wall of the threaded push rod 20, the bottom of the threaded push rod 20 is fixedly connected to a pressure plate 21, the bottom of the unloading rack 22 is fixedly connected to the top of the base 3 via a connecting rod, the top of the loading rack 23 is fixedly connected to the side wall of the fixing plate via a connecting rod, and the toothed ring 17 meshes with the unloading rack 22 and the loading rack 23 respectively;

[0041] It should be noted that after pressing, the drive motor 1 is used to rotate the compacted template 16 to the unloading rack 22, which is the unloading end. After the unloading rack 22 meshes with the toothed ring 17, it drives the toothed ring 17 to rotate. The rotation of the toothed ring 17 drives the connecting ring 19 to rotate, thereby driving the threaded push rod 20 to move upward and push out the powder cake in the template 16. This makes it convenient for the operator to quickly take out the pressed raw material at the unloading end. After the toothed ring 17 rotates to the loading end, the loading rack 23 is used to reset the threaded push rod 20, so that the pressure plate 21 moves down to the lowest surface, which is convenient for loading.

[0042] The further advantage of adopting the above method is that it allows the feeding, pressing and unloading stages to be carried out simultaneously, which makes the pressing speed of raw material powder faster and improves the overall production efficiency.

[0043] Example 3

[0044] refer to Figure 1-11 A hydraulic press 24 is fixedly connected to the top connecting plate of the base 3. A circular plate 25 is connected to the outer wall of the bottom end of the hydraulic press 24. A main suction pipe 28 is provided below the circular plate 25. A piston assembly is connected to the inner wall of the main suction pipe 28. A branch suction pipe 29 is connected to the side wall of the main suction pipe 28. An air outlet valve assembly is connected to the inner wall of the bottom end of the main suction pipe 28. An air intake valve assembly is connected to the inner wall of the bottom end of the branch suction pipe 29.

[0045] Furthermore, the outer wall of the hydraulic press 24 is fixedly connected to the inner wall of the circular plate 25, and a transition plate is slidably connected to the outer wall of the bottom end of the hydraulic press 24. A pressure column 37 is fixedly connected to the bottom end of the hydraulic press 24. The inner wall of the transition plate is connected to the pressure column 37 via a compression spring. The transition plate is fixedly connected to the outer walls of the main suction pipe 28 and the branch suction pipe 29. The side wall of the main suction pipe 28 is fixedly connected to one end of the branch suction pipe 29. The piston assembly consists of a piston rod 26 and a piston plate 27. The two ends of the piston rod 26 are fixedly connected to the bottom end of the circular plate 25 and the top end of the piston plate 27, respectively. The side wall of the piston plate 27 is slidably connected to the inner wall of the main suction pipe 28. A receiving tube 30 is fixedly connected to the outer wall of the bottom end of the tube 28. The air outlet valve assembly consists of a main platform-shaped bucket 34, a main return spring 35, and a main valve ball 36. The air intake valve assembly consists of a secondary platform-shaped bucket 31, a secondary return spring 32, and a secondary valve ball 33. The outer wall of the large opening end of the main platform-shaped bucket 34 is fixedly connected to the inner wall of the bottom end of the main suction tube 28. The outer wall of the large opening end of the secondary platform-shaped bucket 31 is fixedly connected to the inner wall of the bottom end of the branch suction tube 29. The two ends of the main return spring 35 are fixedly connected to the side walls of the main platform-shaped bucket 34 and the main valve ball 36, respectively. The two ends of the secondary return spring 32 are fixedly connected to the side walls of the secondary platform-shaped bucket 31 and the secondary valve ball 33, respectively.

[0046] It should be noted that after the material is fed, the drive motor 1 rotates the loaded template 16 to the bottom of the hydraulic press 24. This is the pressing end. When pressing, the hydraulic press 24 is started to press down, thereby driving the circular plate 25, the adapter plate and the pressure column 37 to press down. The pressure column 37 compacts the powder in the template 16 into a powder cake shape. At the same time, the adapter plate moves down to the top of the template 16 and slides between it and the pressure column 37, so that the piston rod 26 and the piston plate 27 on the circular plate 25 slide in the main suction pipe 28. The gas in the main suction pipe 28 is intermittently discharged from the connection between the main suction pipe 28 and the receiving pipe 30 through the air outlet valve assembly. After compaction, the rapid upward compression spring will cause the adapter plate to reset instantly, thereby resetting the piston plate 27. This causes the air pressure inside the main suction pipe 28 and the branch suction pipe 29 to decrease instantly. The external air pressure is used to press the auxiliary valve ball 33 up, so that the air drives the powder on the surface of the template 16 to be sucked in.

[0047] The further advantage of the above method is that it can compact the raw material powder at the pressing end and draw in the powder remaining on the compacted template 16, thus avoiding affecting the subsequent mixing ratio of raw material powder.

[0048] When using this invention, the drive motor 1 is started and the drive shaft drives the worktable 2 to rotate intermittently. The worktable 2 drives a template 16 to rotate directly below the material changing motor 4, which is the feeding end. The material changing motor 4 is started and the rotating shaft 5 drives the material changing plate 6 to rotate intermittently. After the material changing plate 6 drives a storage box 11 to rotate above the template 16, the electric push rod 7 is controlled to push down a predetermined distance. The electric push rod 7 drives the adjusting rod 8 to move down. The adjusting rod 8 rotates by sliding between its threaded groove and the sliding button 10, so that the adjusting rod 8 drives the discharge cylinder 13 to rotate and move down by the adapter rod 12.

[0049] As the discharge cylinder 13 rotates and moves downward, the raw material powder inside is sprinkled out layer by layer through the discharge hole. At the same time, the rotating multiple adapter rods 12 will stir the powder in the storage box 11 into the extension tube 14 and into the discharge cylinder 13. When moving downward, the adjusting motor 38 drives the adjusting gear 39 to rotate at a certain angle, and drives multiple bevel gears 40 to rotate. Thus, the pin shaft 41 causes the flattening and compacting plate 15 to deflect at a certain angle, so that the lower side of the inclined flattening and compacting plate 15 remains flat, and the sprinkled raw material is rotated and flattened. After the raw material is flattened to the specified height, the multiple flattening and compacting plates 15 are controlled to return to the combined circular plate shape. Then, the electric push rod 7 is used to press down slightly to initially compact the raw material. In this way, multiple raw materials can be combined in layers, and the flattening and compacting plate 15 at the bottom of the discharge cylinder 13 is used to flatten and initially compact the put-in raw material, which improves the speed of layered feeding.

[0050] After the material is fed, the drive motor 1 rotates the loaded template 16 to a position below the hydraulic press 24, which is the pressing end. During pressing, the hydraulic press 24 is activated to press down, thereby driving the circular plate 25, the adapter plate, and the pressure column 37 to press down. The pressure column 37 compacts the powder in the template 16 into a powder cake shape. At the same time, the adapter plate moves down to the top of the template 16 and slides between itself and the pressure column 37, causing the piston rod 26 and piston plate 27 on the circular plate 25 to slide inside the main suction pipe 28, thus drawing gas from the main suction pipe 28. The air is intermittently discharged from the connection between the main suction pipe 28 and the receiving pipe 30 using the air outlet valve assembly. After compaction, the compression spring moves upward quickly, causing the adapter plate to reset instantly, thereby resetting the piston plate 27. This causes the internal air pressure of the main suction pipe 28 and the branch suction pipe 29 to decrease instantaneously. External air pressure is used to press the auxiliary valve ball 33 upward, causing air to carry the powder on the surface of the template 16 into the air. This allows the raw material powder to be compacted at the pressing end, and the powder remaining on the template 16 after compaction to be sucked in, avoiding affecting the subsequent mixing ratio of raw material powder.

[0051] After pressing, the compacted template 16 is rotated to the unloading rack 22 by the drive motor 1. This is the unloading end. The unloading rack 22 meshes with the toothed ring 17, which drives the toothed ring 17 to rotate. The rotation of the toothed ring 17 drives the connecting ring 19 to rotate, thereby driving the threaded push rod 20 to move upward and push out the powder cake in the template 16. This makes it convenient for the operator to quickly take out the pressed raw material at the unloading end. After the toothed ring 17 rotates to the loading end, the threaded push rod 20 is reset by the loading rack 23, so that the pressure plate 21 moves down to the lowest surface, which is convenient for loading. This allows the loading, pressing and unloading stages to be carried out simultaneously, making the pressing speed of the raw material powder faster and improving the overall production efficiency.
