This process is labor-intensive for workers, has a long processing cycle, and results in low efficiency. Furthermore, human error in manual operation leads to uneven powder weight, reducing the quality of the sintered ceramic. Utility Model Content

[0043] The powder conveying mechanism provided by the utility model, powder storage chamber 11 is used to store powder, when needing to discharge, the discharge port is opened, and powder storage chamber 11 and powder outlet chamber 12 are communicated, because powder storage chamber 11 is arranged above powder outlet chamber 12, under the action of gravity, the powder falls into the weighing assembly 2 in powder outlet chamber 12. Weighing assembly 2 weighs the powder of set weight, the discharge port is closed, powder storage chamber 11 and powder outlet chamber 12 are isolated, and the powder in powder storage chamber 11 cannot continue to fall into powder outlet chamber 12, feeding spare 4 extends into the inside of forming cavity 31, and weighing assembly 2 pours the powder to the discharge port 13, and the powder of set weight flows from the discharge port 13 to forming cavity 31 along feeding spare 4. The powder conveying mechanism can guarantee that the powder of same weight falls into forming cavity 31, workers do not need to weigh, the working strength of workers is reduced, and processing efficiency and quality are improved.

[0044] The shape of powder storage chamber 11 and powder outlet chamber 12 can be same or different. Preferably, the shape of powder storage chamber 11 and powder outlet chamber 12 is same, facilitating processing. The bottom of powder storage chamber 11 and the bottom of powder outlet chamber 12 all have guide slopes, the guide slope in powder storage chamber 11 makes the powder automatically flow to the discharge port, and the guide slope in powder outlet chamber 12 makes the powder automatically flow to the discharge port 13, facilitating the powder of set weight to flow into forming cavity 31.

[0045] When processing storage spare 1, one cavity can be arranged in the inside of storage spare 1, and the cavity is separated into powder storage chamber 11 and powder outlet chamber 12 by partition 5, and storage spare 1 can also be provided with two cavities, which are powder storage chamber 11 and powder outlet chamber 12 respectively.

[0046] Referring to Figure 2In the embodiment, the inner part of the storage member 1 is provided with a partition plate 5 between the powder storage chamber 11 and the powder outlet chamber 12, the partition plate 5 is provided with a discharging opening, and the discharging opening is provided with a switch assembly 6 which can be switched between an open state and a closed state to selectively open and close the discharging opening. When the switch assembly 6 is in the open state, the discharging opening is opened, and the powder in the powder storage chamber 11 can flow into the powder outlet chamber 12 through the discharging opening. When the switch assembly 6 is in the closed state, the discharging opening is closed, and the powder storage chamber 11 is isolated from the powder outlet chamber 12, and the powder cannot flow into the powder outlet chamber 12.

[0047] The shape of the discharging opening can be circular or rectangular. Optionally, the shape of the discharging opening is circular, which is convenient for processing. When the switch assembly 6 is in the closed state, the partition plate 5 isolates the powder storage chamber 11 and the powder outlet chamber 12, and the powder is stacked on the partition plate 5. When the switch assembly 6 is in the open state, the discharging opening connects the powder storage chamber 11 and the powder outlet chamber 12, and the powder on the partition plate 5 flows into the powder outlet chamber 12 through the discharging opening.

[0048] The switch assembly 6 can include a switch door plate or a one-way valve. For example, the switch assembly 6 includes a switch plate 61 and a first driving member, the switch plate 61 is slidingly connected or rotatably connected with the partition plate 5, and the first driving member can drive the switch plate 61 to move to selectively open and close the discharging opening.

[0049] The switch plate 61 can be arranged on the upper side of the partition plate 5, on the lower side of the partition plate 5, or in the inner part of the partition plate 5. Preferably, the switch plate 61 is arranged on the lower side of the partition plate 5, so that when the switch plate 61 moves relative to the partition plate 5, the switch plate 61 avoids carrying the powder.

The first driving member is connected with the switch plate 61, and the first driving member can be an electric push rod. When the electric push rod is elongated, the switch plate 61 moves close to the discharging opening to close the discharging opening and isolate the powder storage chamber 11 and the powder outlet chamber 12. When the electric push rod is retracted, the switch plate 61 moves away from the discharging opening to open the discharging opening and make the powder fall into the powder outlet chamber 12.

[0051] In other embodiments, two switch plates 61 can be arranged, and the two switch plates 61 are located on the two sides of the discharging opening.

The switch plate 61 can rotate relative to the partition 5 around the axis of the rotating shaft 62. The rotating shaft 62 is connected to a first driving component, which can be an existing motor that is readily available. When the motor rotates forward, it drives the rotating shaft 62 to rotate, thereby causing the switch plate 61 to rotate downward, opening the discharge port and allowing powder to fall from the powder storage chamber 11 into the powder discharge chamber 12. When the motor rotates in reverse, it drives the rotating shaft 62 to rotate, thereby causing the switch plate 61 to rotate upward, closing the discharge port and isolating the powder storage chamber 11 from the powder discharge chamber 12.

[0053] The switch plate 61 can be a rectangular plate or a semi-circular plate. Preferably, the switch plate 61 is a rectangular plate, which is convenient for processing and manufacturing.

[0054] Weighing component 2 is used to weigh a set weight of powder. In this embodiment, see [link to documentation]. Figure 2 The weighing assembly 2 includes a rotating plate 21, a weighing container 22, and a weighing sensor 23. The rotating plate 21 can rotate around a horizontal axis between a receiving position and a discharging position. The weighing sensor 23 and the weighing container 22 are fixedly connected to the rotating plate 21. The weighing container 22 is used to hold the powder flowing down from the discharge port, and the weighing sensor 23 is used to weigh the powder inside the weighing container 22. The weighing sensor 23 and the weighing container 22 are fixedly connected to the rotating plate 21. When the rotating plate 21 is in the receiving position, the weighing container 22 can receive the powder falling from the discharge port, and the weighing sensor 23 can weigh the weight of the powder inside the weighing container 22. When the rotating plate 21 is in the discharging position, the weighing container 22 can pour the powder inside it into the discharge port.

[0055] The weighing container 22 can be an open cylinder or an open cuboid. Optionally, the weighing container 22 is an open cylinder with a smooth inner wall transition, allowing for smoother powder flow. During installation, when the rotating plate 21 is in the receiving position, the opening of the weighing container 22 is located below the discharge port, facilitating the collection of powder falling from the discharge port. A weighing sensor 23 is installed at the bottom of the weighing container 22 for weighing the powder inside. The weighing sensor 23 and the weighing container 22 can be bonded to the rotating plate 21, simplifying operation.

[0056] The weighing assembly 2 can rotate inside the powder outlet chamber 12 to pour the powder in the weighing container 22 to the discharge opening. The weighing assembly 2 also includes a second driving member 24 which drives the rotation of the rotation plate 21 between the receiving position and the discharging position. When the rotation plate 21 is in the receiving position, the angle between the plane where the rotation plate 21 is located and the horizontal plane is 0-5°. When the rotation plate 21 is in the discharging position, the angle between the plane where the rotation plate 21 is located and the horizontal plane is 160-180°. The second driving member 24 drives the rotation of the rotation plate 21 between the receiving position and the discharging position, so that the weighing container 22 receives the powder or pours the powder to the discharge opening.

[0057] The weighing assembly 2 also includes a rotation shaft 25 which is fixedly connected with the rotation plate 21. One end of the rotation shaft 25 is rotatably connected with the inner wall of the powder outlet chamber 12, and the other end is drivingly connected with the second driving member 24. The second driving member 24 can be an existing motor which is easy to obtain and use. When the rotation plate 21 is in the receiving position, the weighing container 22 receives the powder. After the weighing sensor 23 weighs the powder of the set weight, the discharge opening is closed, the second driving member 24 is driven to rotate in the forward direction to drive the rotation of the rotation shaft 25 and the rotation plate 21, so that the rotation plate 21 rotates from the receiving position to the discharging position, and the powder in the weighing container 22 falls to the discharge opening. The second driving member 24 is driven to rotate in the reverse direction to drive the rotation of the rotation shaft 25 and the rotation plate 21, so that the rotation plate 21 rotates from the discharging position to the receiving position, and the powder flowing out of the discharge opening falls into the weighing container 22.

[0058] The rotation plate 21 can rotate between the receiving position and the discharging position. When the rotation plate 21 is in the receiving position, the angle between the plane where the rotation plate 21 is located and the horizontal plane is 0-5°, for example, 0°, 1°, 2°, 3°, 4° or 5°, so that the powder flowing out of the discharge opening can be received. Alternatively, the angle between the plane where the rotation plate 21 is located and the horizontal plane is 0°. When the rotation plate 21 is in the discharging position, the angle between the plane where the rotation plate 21 is located and the horizontal plane is 160-180°, for example, 160°, 165°, 170°, 175° or 180°, so that the powder in the weighing container 22 can completely flow out. Alternatively, the angle between the plane where the rotation plate 21 is located and the horizontal plane is 180°.

[0059] In order to ensure that the powder flowing out of the weighing container 22 can completely flow into the discharge opening 13, the powder outlet chamber 12 is in the shape of a circular funnel or a square funnel. The powder can flow along the inner wall of the powder outlet chamber 12 to the discharge opening 13, so that the powder poured out of the weighing container 22 can completely flow into the discharge opening 13, ensuring that the weight of the powder falling into the forming cavity 31 each time is the same, and improving the quality of the sintered and formed pottery.

[0060] The feeding component 4 is used to deliver the powder from the outlet 13 into the forming cavity 31 of the collecting component 3. In this embodiment, see... Figure 2 The feeding component 4 includes an outer circumferential surface 41 and a feeding channel 42. The diameter of the outer circumferential surface 41 of the feeding component 4 near the collecting component 3 gradually decreases along the powder flow direction, and the powder flows into the forming cavity 31 from the feeding channel 42. The diameter of the outer circumferential surface 41 of the feeding component 4 near the collecting component 3 gradually decreases along the powder flow direction, which facilitates the insertion of the feeding component 4 into the collecting component 3.

[0061] The feeder 4 can be an existing pipe fitting, such as a stainless steel pipe, which is readily available. The feeder 4 can fall vertically or have an inclined section. For example, see [link to example]. Figure 1 The feeder 4 has an inclined part for easy clamping.

[0062] In this embodiment, the cross-section of the feeding channel 42 is circular, and the diameter of the feeding channel 42 can be varied or constant, depending on the actual practical needs.

[0063] In other embodiments, the cross-section of the feeding channel 42 is rectangular or square.

[0064] In order to prevent powder from flying out of the collecting member 3 in the molding cavity 31, in this embodiment, the powder conveying mechanism also includes a sealing plate 7, which covers the collecting member 3 to seal the molding cavity 31 and prevent powder from flying out of the collecting member 3.

[0065] Specifically, the sealing plate 7 is elastic and has a feeding slot 71, through which the feeding component 4 can pass to extend into the molding cavity 31. The sealing plate 7 covers the molding cavity 31. Due to its elasticity, the sealing plate 7 undergoes elastic deformation at its edge in contact with the collecting component 3, which can compensate for minor gaps between the sealing plate 7 and the collecting component 3, improving the sealing effect. During the process of the feeding component 4 passing through the feeding slot 71, the feeding slot 71 widens to allow the feeding component 4 to enter the molding cavity 31. When the feeding component 4 is inside the molding cavity 31, due to the elasticity of the sealing plate 7, it will wrap around the feeding component 4 within the feeding slot 71, further improving the sealing effect.

[0066] In this embodiment, see Figure 4 The material feeding gap 71 is shaped like a star, which can improve the error rate of the feeding part 4 extending into the forming cavity 31 from the material feeding gap 71.

[0067] It should be noted that the outer circumferential surface 41 of the feeding component 4 is relatively smooth, and the friction between the edge of the sealing plate 7 and the inner wall of the collecting component 3 is greater than the friction between the sealing plate 7 and the feeding component 4. When the feeding component 4 extends into and out of the collecting component 3, the sealing plate 7 will not be moved relative to the collecting component 3 by the feeding component 4, thus improving the sealing effect.

[0068] The utility model also provides a powder filling device, including conveying mechanism 100, elevating system and powder conveying mechanism, collection spare 3 sets up on conveying mechanism 100, conveying mechanism 100 can drive collection spare 3 moves along the first direction. Figure 1 The first direction is indicated by the X direction.

[0069] The powder filling device provided by the utility model, collection spare 3 sets up on conveying mechanism 100, elevating system and feeding spare 4 are connected, because the powder conveying mechanism is used, the powder of set weight can be transported to the forming cavity 31 of collection spare 3, then elevating system drives feeding spare 4 to move up, makes feeding spare 4 separate from collection spare 3, conveying mechanism 100 step -by -step movement makes the collection spare 3 that has contained powder move to the first direction, the collection spare 3 that has not contained powder moves to the below of feeding spare 4, elevating system drives feeding spare 4 to move down, and feeding spare 4 extends into forming cavity 31, and the powder is sent into the inside of collection spare 3 again.The powder filling device can automatically weigh and transport the powder of same weight to each collection spare 3 in turn, reduces the work intensity of worker, improves processing efficiency.

[0070] The elevating system can be a screw nut mechanism, the nut is fixedly connected with the feeding spare 4, and the screw nut moves along the vertical direction under the rotation of the screw rod. The elevating system can also be a telescopic rod driven by hydraulic pressure or air pressure, and the telescopic rod is connected with the feeding spare 4 through a connecting piece. When the telescopic rod is extended or contracted, the feeding spare 4 can move along the vertical direction. The connecting piece can connect the telescopic rod and the feeding spare 4, and the connecting piece can be a present cable tie.

[0071] The powder filling device further comprises a containing piece 8 for containing the collection spare 3. As shown in Figure 1 The containing piece 8 is arranged on the conveying mechanism 100, and the containing piece 8 is provided with a plurality of containing grooves 81. The plurality of containing grooves 81 are arranged at intervals along the first direction, and one collection spare 3 is arranged in each containing groove 81, thereby improving the powder filling efficiency. The shape of the containing groove 81 is the same as the bottom of the collection spare 3, and the containing groove 81 is a circular groove, which is convenient for containing the collection spare 3.

[0072] In use, the lifting mechanism drives the feeding member 4 to move downward, so that the feeding member 4 extends into the forming cavity 31 of the collecting member 3. The first driving member drives the switch plate 61 to move to open the discharging port, and the powder in the powder storage chamber 11 falls into the weighing container 22 through the discharging port, and the weighing sensor 23 weighs the mass of the powder in the weighing container 22, when the mass reaches the set weight, the first driving member drives the switch plate 61 to move to close the discharging port, and the powder storage chamber 11 is isolated from the powder outlet chamber 12. The second driving member 24 drives the rotating plate 21 to rotate to the discharging position, and the powder in the weighing container 22 flows to the discharging port 13, and then enters the forming cavity 31 through the feeding channel 42. Then, the lifting mechanism drives the feeding member 4 to move downward, so that the feeding member 4 is separated from the collecting member 3, and the conveying mechanism 100 steps to move, so that the collecting member 3 containing the powder moves in the first direction, and the collecting member 3 not containing the powder moves to the lower side of the feeding member 4, and at the same time, the second driving member 24 drives the rotating plate 21 to rotate to the receiving position, so that when the discharging port is opened, the powder can fall into the weighing container 22. The above steps are repeated to realize automatic weighing and collecting of the powder, and the efficiency and quality of the powder processing are improved.
