A ceramic centrifugal blank-making device

Abstract

This utility model provides a ceramic centrifugal mold-making device, including a bracket with a tooling fixture on it. The bottom of the tooling fixture has a rotary joint that rotatably connects to the bracket, and the bottom of the rotary joint has a docking hole. A fixed frame is located below the bracket, and a vertically arranged lifting mechanism is located on the fixed frame. A centrifugal mechanism is vertically mounted on the lifting mechanism and rises with the lifting mechanism to engage with the docking hole. The centrifugal mechanism is driven to move up and down by the lifting mechanism. The rotary joint in the centrifugal mechanism quickly engages with the rotary joint at the bottom of the tooling fixture, allowing the tooling fixture to rotate on the bracket. This centrifuges the slurry inside the mold, causing it to distribute evenly on the inner wall of the mold under centrifugal force. This allows the mold to complete the centrifugation operation directly during the post-slurry injection process, eliminating the need to transfer the mold to a separate centrifuge, significantly shortening the production cycle, improving production efficiency, and saving time and costs.

Description

Technical Field

[0001] This utility model relates to the field of ceramic production equipment technology, specifically to a ceramic centrifugal embryo-forming device. Background Technology

[0002] In the ceramics industry, the production and shaping of daily-use ceramics mostly employs slip casting. Slip casting is relatively simple: slurry made from the raw material is poured into a plaster mold. Because plaster molds are absorbent, the water in the slurry near the inner wall of the mold is absorbed by the porous plaster, forming a layer of clay on the inner wall of the mold with the same shape as the mold's inner wall. This clay layer thickens over time. After a period of time, the excess slurry is poured off, while the clay layer near the inner wall of the plaster mold remains inside. After another period of time, the clay layer naturally shrinks and detaches from the mold, allowing the rough blank to be removed.

[0003] In existing technologies, if only slurry is injected into the mold in a ceramic blank-making production line, the produced products may have uneven thickness. In this case, the mold needs to be rotated during slurry injection. However, most existing blank-making devices are separate from the conveying devices in the production line. The mold needs to be transferred to the blank-making device for centrifugal rotation, which wastes time and increases costs, and is not conducive to improving production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a ceramic centrifugal blank-making device, which aims to solve the problem in the prior art that the mold needs to be transferred to the blank-making device for centrifugal rotation, resulting in wasted time and increased costs, which is not conducive to improving production efficiency.

[0005] To achieve the above objectives, this utility model provides a ceramic centrifugal preform making device, comprising: a bracket, on which a tooling fixture is provided, the bottom of which is provided with a rotary joint rotatably connected to the bracket, and the bottom of the rotary joint is provided with a docking hole; a fixed frame, disposed below the bracket, on which a vertically arranged lifting mechanism is provided; and a centrifugal mechanism, vertically disposed on the lifting mechanism, the centrifugal mechanism including a drive motor and a rotary docking joint, the rotary docking joint being sleeved on the output shaft end of the drive motor for rising with the lifting mechanism and docking with the docking hole.

[0006] Furthermore, at least two of the tooling fixtures are provided on the bracket, and the number of centrifugal mechanisms corresponds to the number of tooling fixtures and is provided on the lifting mechanism.

[0007] Furthermore, the bracket is provided with a connecting frame for installing a rotary joint. The rotary joint is vertically installed on the connecting frame through a bearing. The bottom of the connecting frame is provided with a positioning hole. A return spring is vertically installed in the docking hole. The lower end of the return spring is provided with a transverse pin in the docking hole. The transverse pin is located in the positioning hole in the reset state.

[0008] Furthermore, the lifting mechanism includes a fixed base plate, a lifting seat, and a first lifting cylinder. The fixed base plate is stacked on the fixed frame, and the first lifting cylinder is vertically mounted on the fixed base plate. The piston rod end of the first lifting cylinder is vertically connected to the lifting seat. The lifting seat is provided with a bearing sleeve, and the drive motor and the rotary connector are vertically connected to the lifting seat through the bearing sleeve.

[0009] Furthermore, a first guide rail seat is vertically provided on one side of the lifting seat on the fixed base plate, and the first guide rail seat is connected to the lifting seat through a guide rail slider.

[0010] Furthermore, the bracket has positioning interfaces on both sides, and the fixing frame has a lifting and positioning mechanism for inserting into the positioning interfaces.

[0011] Furthermore, the lifting and positioning mechanism includes a fixed connecting plate, a limiting seat, and a second lifting cylinder. The second lifting cylinder is vertically mounted on the fixed connecting plate, and the limiting seat is vertically mounted on the piston rod end of the second lifting cylinder and located below the positioning interface.

[0012] Furthermore, the upper end of the limiting seat is provided with a rolling bearing that can contact the inner wall of the positioning interface.

[0013] Furthermore, a second guide rail seat is provided on one side of the second lifting cylinder, and the limiting seat is connected to the second guide rail seat through a guide rail slider.

[0014] The ceramic centrifugal mold-making device provided by this utility model, compared with the prior art, uses a bracket to connect to the conveying device in the production line, and a fixed frame to connect to the frame inside the conveying device. The centrifugal mechanism is driven to move up and down by a lifting mechanism. The rotating joint in the centrifugal mechanism and the rotating joint at the bottom of the tooling fixture are quickly engaged and connected, allowing the tooling fixture to rotate on the bracket to centrifuge the slurry in the mold. Under the action of centrifugal force, the slurry is evenly distributed on the inner wall of the mold. The mold can directly complete the centrifugal operation during the conveying process after slurry injection, eliminating the step of transferring the mold to an independent centrifugal device, greatly shortening the production cycle, improving production efficiency, and saving time and costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components.

[0027] like Figures 1 to 4As shown, a ceramic centrifugal embryo-making device includes a bracket 10, a fixed frame 20, and a centrifugal mechanism.

[0028] The bracket 10 is provided with a tooling fixture 11 for clamping ceramic grouting molds. The bottom of the tooling fixture 11 is provided with a rotary joint 12 that is rotatably connected to the bracket 10. The bottom of the rotary joint 12 is provided with a docking hole 13.

[0029] The fixing frame 20 is located below the bracket 10, and the fixing frame 20 is equipped with a vertically arranged lifting mechanism. The centrifugal mechanism is vertically arranged on the lifting mechanism. The centrifugal mechanism includes a drive motor 31 and a rotary connector 30. The rotary connector 30 is sleeved on the output shaft end of the drive motor 31 and is used to rise with the lifting mechanism to mate with the docking hole 13.

[0030] In practical implementation, the bracket 10 is used to connect to the conveying device in the production line, and the fixed frame 20 is used to connect to the frame inside the conveying device and is located below the bracket 10. The tooling fixture 11 is used to clamp the ceramic slurry mold. When the ceramic slurry mold is slurryed in the conveying device and passes through the centrifugal mechanism, the lifting mechanism drives the centrifugal mechanism to rise. The rotating connector 30 and the rotating connector 12 at the bottom of the tooling fixture 11 are engaged and connected through the docking hole 13. The drive motor 31 drives the rotating connector 30 to rotate, thereby driving the tooling fixture 11 on the bracket 10 to rotate, centrifuging the slurry in the ceramic slurry mold, so that the slurry is evenly distributed on the inner wall of the mold under the action of centrifugal force. After the centrifugal rotation is completed, the lifting mechanism drives the centrifugal mechanism to fall, and the conveying device drives the mold that has completed centrifugation to move forward step by step, and then rotates and centrifuges the subsequent ceramic slurry molds that pass through the centrifugal mechanism again.

[0031] The docking hole 13 and the rotary connector 30 are shaped to match each other. The docking hole 13 can be rectangular, triangular, or polygonal. In this embodiment, the docking hole 13 is rectangular to facilitate docking and positioning.

[0032] In this embodiment, at least two tooling fixtures 11 are provided on the bracket 10, and the number of centrifugal mechanisms corresponds to the number of tooling fixtures 11, and they are arranged on the lifting mechanism. Batch processing can be performed, improving production efficiency.

[0033] In this embodiment, the bracket 10 is provided with a connecting frame 16 for mounting the rotary joint 12. The rotary joint 12 is vertically mounted on the connecting frame 16 through a bearing. The bottom of the connecting frame 16 is provided with a positioning hole 17. A return spring 14 is vertically provided in the docking hole 13. The lower end of the return spring 14 is located in the docking hole 13 and a transverse pin 15 is provided. The transverse pin 15 is located in the positioning hole 17 in the reset state.

[0034] In practice, the bottom of the tooling fixture 11 is locked to the positioning hole 17 at the bottom of the connecting frame 16 via a transverse pin 15, preventing the tooling fixture 11 from rotating on the bracket 10. The tooling fixture 11 can only rotate on the bracket 10 when the rotary connector 30 is inserted into the docking hole 13 and the transverse pin 15 is pushed upward out of the positioning hole 17. After the rotary connector 30 is removed from the docking hole 13, the transverse pin 15 returns to its original position in the positioning hole 17 via the return spring 14, thus locking the tooling fixture 11 in rotation.

[0035] In this embodiment, the lifting mechanism includes a fixed base plate 21, a lifting seat 22, and a first lifting cylinder 23. The fixed base plate 21 is stacked on the fixed frame 20, and the first lifting cylinder 23 is vertically mounted on the fixed base plate 21. The piston rod end of the first lifting cylinder 23 is vertically connected to the lifting seat 22. The lifting seat 22 is provided with a bearing sleeve 32, and the drive motor 31 and the rotary connector 30 are vertically connected to the lifting seat 22 through the bearing sleeve 32.

[0036] In practice, the centrifugal mechanism is vertically mounted on the lifting seat 22. The centrifugal mechanism on the lifting seat 22 is lifted and lowered by the first lifting cylinder 23, so that the rotary joint 30 can dock and separate from the rotary joint 12 at the bottom of the tooling fixture 11.

[0037] Specifically, a first guide rail seat 24 is vertically provided on one side of the lifting seat 22 on the fixed base plate 21. The first guide rail seat 24 is connected to the lifting seat 22 through a guide rail slider. This makes the lifting seat 22 more stable and smooth when the first lifting cylinder 23 drives it to lift and lower, and also improves the docking accuracy between the rotary joint 30 and the rotary joint 12.

[0038] In this embodiment, the bracket 10 is provided with positioning interfaces 18 on both sides, and the fixing frame 20 is provided with a lifting positioning mechanism for inserting the positioning interfaces 18, which is used to prevent the bracket 10 from swaying laterally, and also helps to dock and position the rotating connector 30 and the rotating connector 12.

[0039] Specifically, the lifting and positioning mechanism includes a fixed connecting plate 40, a limiting seat 41, and a second lifting cylinder 42. The second lifting cylinder 42 is vertically mounted on the fixed connecting plate 40. The limiting seat 41 is vertically mounted on the piston rod end of the second lifting cylinder 42 and located below the positioning interface 18. The upper end of the limiting seat 41 is provided with a rolling bearing 43 that can contact the inner side wall of the positioning interface 18. A second guide rail seat 44 is provided on one side of the second lifting cylinder 42. The limiting seat 41 and the second guide rail seat 44 are connected by a guide rail slider.

[0040] In practical implementation, when the ceramic grouting mold is grouted in the conveying device and passes through the centrifugal mechanism, the second lifting cylinder 42 first drives the limiting seat 41 to extend into the positioning interface 18, and abuts against the inner side wall of the positioning interface 18 through the rolling bearing 43, which plays a role in lateral positioning of the bracket 10. Then, the lifting mechanism drives the centrifugal mechanism to rise, and the rotating joint 30 and the rotating joint 12 at the bottom of the tooling fixture 11 are engaged and connected through the docking hole 13, which centrifugally rotates the mud in the ceramic grouting mold, which can effectively limit the swing and displacement of the bracket 10 under the action of centrifugal force, and play a role in positioning and limiting the bracket 10.

[0041] The ceramic centrifugal mold-making device provided by this utility model, compared with the prior art, has a bracket 10 for connecting to the conveying device in the production line, a fixed frame 20 for connecting to the frame inside the conveying device, and a centrifugal mechanism for lifting and moving by a lifting mechanism. The rotating joint 30 in the centrifugal mechanism is quickly engaged with the rotating joint 12 at the bottom of the tooling fixture 11, allowing the tooling fixture 11 to rotate on the bracket 10, centrifugally rotating the slurry in the mold. This causes the slurry to be evenly distributed on the inner wall of the mold under the action of centrifugal force, allowing the mold to complete the centrifugal operation directly during the conveying process after slurry injection, eliminating the step of transferring the mold to an independent centrifugal device, greatly shortening the production cycle, improving production efficiency, and saving time and costs.

[0042] Where there is no conflict, the above embodiments and features can be combined with each other.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
