Description

Technical Field

[0001] This application relates to the field of zirconia powder processing technology, and in particular to a feeding mechanism for zirconia powder grading. Background Technology

[0002] In the production of zirconia powder, classification is a crucial step, aiming to separate zirconia powder of different particle sizes to meet the stringent particle size requirements of various applications. The feeding mechanism, as a key piece of equipment before classification, directly impacts the classification effect and production efficiency.

[0003] Existing feeding mechanisms for zirconia powder classification mostly use a single spiral blade conveying method. During the conveying process, the interaction force between zirconia powder particles can easily lead to agglomeration. Agglomerated powder can easily cause blockage in the conveying pipeline, affecting the feeding efficiency. In addition, the disassembly process of existing feeding mechanisms is relatively cumbersome and inconvenient for internal cleaning. Utility Model Content

[0008] Preferably, a first gear is fixedly mounted on the other end of the first rotating shaft, and a second gear is fixedly mounted on the other end of the second rotating shaft, with the first gear and the second gear meshing with each other.

[0015] 2. The easy-to-disassemble component of this utility model is provided with clamping seats and clamping blocks on both sides of the feeding cylinder and the quick-release cover. The clamping seats and clamping blocks are fixedly installed by threaded rods.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a feeding mechanism for classifying zirconia powder, including a classifying device 1. A feeding hopper 2 is connected to the feeding port at the top of the classifying device 1. The other end of the feeding hopper 2 is connected to the discharge port at one end of the feeding cylinder 4. The other end of the feeding cylinder 4 is fixedly connected to the top of the fixing seat 3 at the edge of the classifying device 1. A feeding structure is provided inside the feeding cylinder 4. A feeding hopper 5 is provided on the feeding cylinder 4 near the edge of the fixing seat 3. A quick-release cover 6 is also provided on the feeding cylinder 4.

[0024] refer to Figure 3 and Figure 4The feeding structure includes a first rotating shaft 7 and a second rotating shaft 8 installed inside the feeding cylinder 4. One end of the first rotating shaft 7 and the second rotating shaft 8 passes through a shaft hole opened at one end of the feeding cylinder 4 and is connected to a bearing seat. The other end of the first rotating shaft 7 and the second rotating shaft 8 passes through a shaft hole opened on the fixed seat 3. A first gear 9 is fixedly installed on the other end of the first rotating shaft 7, and a second gear 10 is fixedly installed on the other end of the second rotating shaft 8. The first gear 9 and the second gear 10 mesh with each other. The other end of the first rotating shaft 7 is also connected to a transmission shaft provided at the output end of the drive motor 11. The drive motor 11 is fixed on a motor base provided on the fixed seat 3. Spiral blades 12 are respectively installed on the first rotating shaft 7 and the second rotating shaft 8. Multiple openings 13 are opened on the spiral blades 12. A mounting block is also provided between the spiral blades 12 on the first rotating shaft 7 and the second rotating shaft 8. A dispersing rod 14 is installed on the mounting block. More specifically, during feeding, the drive motor 11 operates, causing the transmission shaft connected to the output end to drive the first rotating shaft 7 to rotate. When the first rotating shaft 7 rotates, the first gear 9 installed at one end meshes with the second gear 10 installed at one end of the second rotating shaft 8, causing the first rotating shaft 7 and the second rotating shaft 8 to rotate simultaneously. This causes the spiral blades 12 installed on the first rotating shaft 7 and the second rotating shaft 8 to rotate, driving the zirconia powder to the discharge port. The spiral blades 12 have multiple openings 13, which can disperse the zirconia powder during feeding, preventing the zirconia powder from agglomerating. At the same time, multiple dispersing rods 14 are also installed between the spiral blades 12 on the first rotating shaft 7 and the second rotating shaft 8. When the first rotating shaft 7 and the second rotating shaft 8 rotate, the dispersing rods 14 can disperse the zirconia powder, thereby further preventing the zirconia powder from agglomerating and improving the feeding efficiency.

[0025] refer to Figure 2 and Figure 5 An easy-to-disassemble component is also provided between the feeding cylinder 4 and the quick-release cover 6. The easy-to-disassemble component includes multiple sets of symmetrical clamping seats 15 set on the two side walls of the feeding cylinder 4. The clamping seat 15 is provided with a clamping block 16 inside. The other end of the clamping block 16 is connected to the side wall of the quick-release cover 6. The side wall of the clamping seat 15 and the clamping block 16 is provided with a threaded hole. A threaded rod 17 is fitted inside the threaded hole. More specifically, by setting the clamping seat 15 and the clamping block 16 on the two side walls of the feeding cylinder 4 and the quick-release cover 6, and fixing the clamping seat 15 and the clamping block 16 with the threaded rod 17, when cleaning the inside of the feeding cylinder 4, the quick-release cover 6 can be separated from the feeding cylinder 4 by rotating the clamping block 16 and the threaded rod 17 fitted inside the threaded hole on the side wall of the clamping seat 15, thereby facilitating the cleaning of the inside of the feeding cylinder 4 and improving the convenience of cleaning.

[0026] The implementation principle of the feeding mechanism for zirconia powder grading in this embodiment is as follows: In use, zirconia powder is placed inside the feeding cylinder 4 through the feeding hopper 5. The drive motor 11 drives the first rotating shaft 7 to rotate. When the first rotating shaft 7 rotates, the first gear 9 and the second gear 10 mesh and rotate, causing the first rotating shaft 7 and the second rotating shaft 8 to rotate simultaneously. This causes the spiral blades 12 to rotate, carrying the zirconia powder to the outlet and then through the feeding hopper 2 into the grading device 1. The spiral blades 12 have multiple openings 13, allowing... When conveying zirconia powder, it can be dispersed to prevent zirconia powder from agglomerating. At the same time, the rotation of the first rotating shaft 7 and the second rotating shaft 8 drives multiple dispersing rods 14 to disperse the zirconia powder, thereby further preventing the zirconia powder from agglomerating and improving the feeding efficiency. When it is necessary to clean the inside of the feeding cylinder 4, the quick-release cover 6 can be separated from the feeding cylinder 4 by rotating the locking block 16 and the threaded rod 17 adapted in the threaded hole on the side wall of the locking seat 15, thereby facilitating the cleaning of the inside of the feeding cylinder 4 by the staff and improving the convenience of cleaning.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
