Description

[0002] With the development of materials science and computer technology, CAD-CAM technology has been applied to the fabrication of dentures. Currently, Cercon, a zirconia computer-aided all-ceramic crown, has become the most successful product among all-ceramic crowns.

[0003] When calcining zirconia, it is necessary to prepare zirconia cakes. The preparation of these cakes involves adding various powders one by one into a mold, and then using a hydraulic device to extrude and shape the powders into finished cakes. The preparation of these cakes requires frequent addition of different powders, followed by repeated extrusion. Currently, this is mainly done manually, which is labor-intensive and prone to weighing errors. Mechanical operation requires frequent movement of the cakes to the corresponding powder addition points, resulting in complex programming, a high error rate, extremely low processing efficiency, and very high equipment precision requirements. Therefore, a multi-powder, high-precision powder pressing device is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing manual operation, which involves a large workload, weighing errors, and the need for frequent movement of cake material to the corresponding powder addition position during mechanical operation, resulting in extremely low processing efficiency and high precision requirements for the equipment. The proposed invention is a multi-material high-precision powder pressing device. It uses multiple storage boxes containing different powders, which are evenly arranged in a ring on a support ring. A planetary conversion disk drives the powder conveying pipes for conveying. During the revolution of the planetary conversion disk, the output position of different powders is changed, thereby achieving the effect of feeding one by one during the revolution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] 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.

[0025] Reference Figure 1-5 A multi-ingredient high-precision powder pressing device includes a powder pressing table 1. The powder pressing table 1 is connected to a feeding plate 3 via an arc-shaped support plate 2. A hydraulic pressure cylinder 4 is installed on the feeding plate 3. The hydraulic pressure cylinder 4 is a hydraulic component and is existing technology, so it will not be described in detail here. The output end of the hydraulic pressure cylinder 4 is connected to the powder pressing plate 5. A support ring 6 is fixedly connected to the outer wall of the feeding plate 3. Multiple storage boxes 7 are installed on the support ring 6. The multiple storage boxes 7 hold different powders and are evenly arranged in a ring on the support ring 6. The design distance of the storage boxes 7 is designed according to the required powder type.

[0026] During the downward movement of the powder pressing disc 5, the powder in the pressing mold 14 is effectively pressed.

[0027] Furthermore, a storage cavity is provided inside the storage box 7, and an "L"-shaped weighing seat 15 is fixedly installed on the inner side wall of the support ring 6. A connecting groove is provided on the weighing seat 15, and a T-shaped limiting block 16 adapted to the connecting groove is fixedly connected to the side wall of the storage box 7. A gravity sensor 17 is provided at the bottom of the weighing seat 15, and a display screen is provided on the support ring 6. The display screen is electrically connected to the gravity sensor 17.

[0028] The display screen reflects the measurement results of the gravity sensor 17 in real time. This ensures that when the raw materials in the storage box 7 are insufficient, the display screen can promptly reflect the data and remind the staff to replenish the powder in a timely manner.

[0029] The storage box 7 is equipped with a control motor 8, which is connected to a conveyor plate 9 via a weighing assembly. Furthermore, the weighing assembly includes a rotating shaft 18 connected to the output end of the control motor 8. The conveyor plate 9 is fixedly connected to the rotating shaft 18. A quantitative outlet 19 is provided on the conveyor plate 9, and a discharge port adapted to the quantitative outlet 19 is provided at the bottom of the storage chamber.

[0030] It should be noted that the volume of the quantitative inlet 19 is set according to the different powder requirements, so as to achieve the effect of quantitative conveying during the rotation of the conveying disc 9.

[0031] A drive motor 10 is provided on the support ring 6. The drive motor 10 is a type of servo motor, which is existing technology and will not be described in detail here. The output end of the drive motor 10 is connected to a drive outer ring 11 through a drive assembly. Further, the drive assembly includes a bearing outer ring 20 fixedly connected to the bottom of the support ring 6. The drive outer ring 11 is rotatably mounted on the bearing outer ring 20. The output end of the drive motor 10 is fixedly connected to a drive gear 21 that penetrates the side wall of the support ring 6. The drive gear 21 meshes with the drive outer ring 11.

[0032] It is worth noting that the outer support ring 20 and the inner support ring 24 can effectively support the planetary conversion disk 12 located therein. In this scheme, in order to reduce the friction between the planetary conversion disk 12 and the outer support ring 20 and the inner support ring 24, the bottom of the planetary conversion disk 12 is densely covered with balls, thereby reducing the friction.

[0033] The inner wall of the drive outer ring 11 is meshed with a planetary conversion disk 12. The planetary conversion disk 12 is provided with a material powder conveying pipe. Further, the material powder conveying pipe consists of an inclined pipe 25, an upper connecting pipe 26 and a discharge pipe 27. The feeding disk 3 is provided with a mating port that is adapted to the upper connecting pipe 26. The planetary conversion disk 12 is provided with a connection port that penetrates the side wall. The upper connecting pipe 26 is fixedly connected to the inner wall of the connection port.

[0034] When the material powder conveying pipe moves to the mating port on the feeding plate 3, the mating port will be aligned with the upper connecting pipe 26 on the material powder conveying pipe; and at this time, the feeding pipe 27 is also directly above the pressing mold 14.

[0035] The planetary conversion disk 12 is connected to the application disk 3 via a self-driving assembly. Further, the self-driving assembly includes a fixing ring 22 fixedly connected to the application disk 3. A drive internal gear ring 23 that meshes with the planetary conversion disk 12 is fixedly connected to the outer wall of the fixing ring 22. A bearing inner ring 24 that supports the planetary conversion disk 12 is fixedly connected to the bottom of the fixing ring 22.

[0036] It should be noted that the rotation of the outer drive ring 11 will cause the planetary conversion disk 12, which is meshed with it, to rotate. The planetary conversion disk 12 will rotate on its own axis, and during the rotation of the planetary conversion disk 12, due to the meshing connection with the inner drive gear ring 23, the planetary conversion disk 12 will revolve around the fixed ring 22. This design utilizes the revolution of the planetary conversion disk 12 to change the output position of different powder materials, thereby achieving the effect of feeding materials one by one during the revolution. By designing the rotation of the planetary conversion disk 12, the rotation of the powder conveying pipe on it is realized, which drives the powder conveying pipe located in the middle position of the planetary conversion disk 12 to rotate, so that the powder conveying pipe can be conveyed when it stops rotating. During the rotation of the powder conveying pipe, the hydraulic pressure cylinder 4 drives the powder pressing disk 5 to perform the pressing process.

[0037] Thus, when the discharge pipe 27 at the bottom of the powder conveying pipe corresponds to the powder pressing trough 13, the powder is conveyed into the pressing mold 14. When it is rotated to other positions, the powder conveying pipe is removed, so that the hydraulic pressure cylinder 4 can drive the powder pressing plate 5 to perform extrusion processing. The structure is reasonable and compact.

[0038] The powder pressing table 1 is provided with a powder pressing trough 13, and a detachable pressing mold 14 is provided inside the powder pressing trough 13. The pressing mold 14 is through-type, and the inner diameter of the pressing mold 14 is the same as the outer diameter of the powder pressing plate 5.

[0039] When feeding and pressing various powders layer by layer, the present invention places the required powders into the corresponding storage boxes 7 in sequence according to the moving direction of the planetary conversion disk 12. At this time, the gravity sensor 17 set at the bottom of the storage box 7 will measure the weight of the powder in the storage box 7.

[0040] The control motor 8 drives the connected conveyor plate 9 to rotate. As the conveyor plate 9 rotates, it moves the metering port 19 on the conveyor plate 9 to the bottom of the storage box 7. At this time, the powder in the storage box 7 will enter the metering port 19. Since the volume of the metering port 19 is fixed, the powder conveyed through the conveyor plate 9 each time is of a pre-designed specification, realizing the metered conveying of powder at different positions.

[0041] The drive motor 10 drives the drive gear 21 connected to its output end to rotate. The drive outer ring 11, which meshes with the drive gear 21, rotates. During the rotation, it drives the planetary conversion disk 12, which meshes with it, to rotate. The planetary conversion disk 12 rotates on its own axis. During the rotation of the planetary conversion disk 12, it revolves around the fixed ring 22 due to the meshing connection between it and the drive inner gear ring 23.

[0042] When the planetary conversion disk 12 drives the powder conveying pipe to rotate, it will also drive the powder conveying pipe to move. When the powder conveying pipe moves to the mating port on the feeding disk 3, the mating port will be aligned with the upper connecting pipe 26 on the powder conveying pipe. When the alignment is achieved, the drive motor 10 stops for a few seconds. During this process, the control motor 8 drives the conveying disk 9 to rotate. During the rotation, the metered powder in the metering port 19 is conveyed to the mating port. Under the action of the powder conveying pipe, the powder will be conveyed from the bottom to the pressing mold 14 to complete the feeding process.

[0043] After the feeding is completed, the drive motor 10 controls the planetary conversion disk 12 to rotate. During the rotation, the planetary conversion disk 12 is moved to the other powder adding parts. During this process, the powder conveying pipe will be moved away from the pressing mold 14 during the rotation. At this time, the hydraulic pressure cylinder 4 drives the powder pressing disk 5 to move down, so that the powder pressing disk 5 can effectively squeeze the powder located in the pressing mold 14, thereby gradually realizing the automated processing of feeding and squeezing different powders one by one.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
