Description

Technical Field

[0001] The present invention relates to the technical field of ceramic processing, and in particular to a press for producing high-aluminum ceramic materials and a method of using the press. Background Art

[0002] Ceramics is a general term for pottery and porcelain. Common ceramic materials include clay, alumina, kaolin, etc. Ceramic materials usually have high hardness but relatively poor plasticity.

[0003] During the production process, many ceramic products need to go through a stamping process. Traditional stamping processes require the use of a stamping device to stamp and form ceramic materials. However, the stamping devices in the prior art still have the following shortcomings during the stamping process: 1. When using a stamping device to process ceramics, it is necessary to manually add ceramic material and place the mold under the stamping head for stamping. The addition of ceramic material and the stamping operation are performed separately, which not only reduces production efficiency but also increases the complexity of the production process; 2. During stamping, gradually increasing pressure pushes the ceramic powder closer together and deforms it. During the pressing process, the ceramic powder particles undergo plastic deformation and rearrange themselves, forming a tighter structure. However, this creates friction between the ceramic and the mold's inner wall, making it difficult to manually remove the ceramic from the mold later.

[0004] In response to the above problems, the present invention document proposes a press for producing high-aluminum ceramic materials and a method for using the same. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the existing filling and stamping operations being carried out separately, which seriously affects the ceramic processing efficiency and the friction between the ceramic and the mold affects the removal of the ceramic, and to propose a press for the production of high-aluminum ceramic materials and its use method.

The swing arm ends up being rotated by the hook portion. The swing arm ends up being rotated by the hook portion. On both sides of the movable plate, the bottom ends of the two connecting rods are rotatably connected to the top ends of the two insertion rods respectively. Two fixed plates are fixed in the frame, and the two fixed plates are respectively located above and below the movable plate. The bottom ends of the two insertion rods slide through the fixed plate located below. The reciprocating movement of the movable plate can drive the insertion rod to move up and down through the connecting rod, and the conveyor belt is used to transport the fallen ceramics; when the second rotating ring drives the arc plate to rotate, the arc plate releases the push on the vertical plate, and the movable plate and the vertical plate move toward the middle under the elastic force of the spring, and the movable plate drives the connecting rod to rotate through the pin rod, and the connecting rod pushes the insertion rod to insert into the through hole and pushes the push rod and the sliding plate downward to push out the ceramics in the mold.

The ends of the two push rods away from the movable plate are fixedly connected to the sliding plate, and the outer walls of the two push rods are sleeved with tension springs fixedly connected to the sliding plate. The ends of the two tension springs away from the sliding plate are respectively fixedly connected to the corresponding cross bars for driving the sliding plate to reset; the chain conveyor moves the mold to the bottom, and the two molds are just on the same axis, the insertion rod is aligned with the push rod, and the connecting rod pushes the insertion rod to insert into the through hole and push the push rod and the sliding plate downward, pushing the ceramic in the mold out, and the ceramic just falls on the conveyor belt, and the ceramic is transported to the next process.

The top ends of the two guide rods slide and extend to the top of the storage cylinder to ensure smooth lifting and lowering of the sealing cylinder and the stamping plate.

[0012] In a possible design, a support plate is fixed to the side of the two fixed plates away from each other, and the support plate is located between the two chain conveyor belts for supporting the mold; when the stamping plate is stamping, the support plate supports the mold.

A plurality of discharge pipes are fixed at the bottom, and the discharge pipes are connected to the annular liquid storage cylinder. A solenoid valve is provided on the discharge pipe to drip the lubricant onto the rotating disk. When the solenoid valve on the discharge pipe is opened, the lubricant in the annular liquid storage cylinder drips onto the frustum. The rotating rod drives the rotating cylinder to rotate through the synchronous wheel and the synchronous belt. The rotating cylinder drives the lead screw to rotate. The rotation of the lead screw drives the rotating disk and the cotton ring to extend into the mold. When the frustum rotates, the lubricating oil on it adheres to the cotton ring under the action of centrifugal force.

S2: The punching plate moves up, and the transmission mechanism drives the first rotating ring and the second rotating ring to rotate. The magnetic attraction between the first magnet and the second magnet drives the first bevel ring and the second bevel ring to rotate. The prying plate stirs the raw material and accelerates the injection into the mold. S3, the nut ring rotates in the opposite direction, the screw drives the sealing cylinder and the punching plate to move downward, the punching plate punches the raw material in the die, and the sealing cylinder closes the discharge port at the same time, and the storage cylinder continues to feed the material for subsequent filling; S4.

The empty mold enters the U-shaped frame, the solenoid valve opens, and the lubricant drips onto the frustum; the rotating rod drives the rotating cylinder and the lead screw to rotate, driving the rotating disk and the cotton ring into the mold. The rotation of the frustum causes the lubricant to adhere to the cotton ring, cleaning and lubricating the inner wall of the mold, reducing friction and wear.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1: Reference Figure 1 and Figure 2 A press used in ceramic production comprises a frame 1, within which a conveyor belt 3 and a conveying mechanism are disposed, with the conveyor belt 3 positioned below the conveying mechanism. Multiple molds 4 are equidistantly fixed to the outer wall of the conveying mechanism for forming ceramic materials. The conveying mechanism comprises two chain conveyor belts 2, which circulate the molds 4 within the frame 1.

[0021] Reference Figure 1 、 Figure 3 and Figure 4Above the frame 1, a storage barrel 5 is fixed via a connecting frame. The storage barrel 5 is located above the mold 4 and is used to store ceramic raw materials. A discharge port 13 is provided at the bottom of the storage barrel 5. The discharge port 13 cooperates with the mold 4 and is used to add raw materials into the mold 4. A screw rod 6 slides through the top of the storage barrel 5. The bottom end of the screw rod 6 extends into the storage barrel 5 and is fixed with a punching plate 12. The outer diameter of the punching plate 12 matches the inner diameter of the discharge port 13, which is used to block the discharge port 13. When the punching plate 12 descends, the raw materials in the mold 4 can be punched and formed.

[0022] Reference Figure 2 、 Figure 7 and Figure 8 In addition, the press also includes a movable plate 27 that slides through the frame 1. Insertion rods 36 are provided on both sides of the bottom of the movable plate 27. When the mold 4 moves below the chain conveyor 2, the insertion rods 36 can be inserted into the mold 4 to push out the stamped ceramic for subsequent collection and processing.

[0023] Reference Figure 3 and Figure 4 To enable automatic filling and stamping of raw materials, the press is equipped with a feeding mechanism. This mechanism includes a nut ring 7 that rotates on the top of the storage barrel 5 and is threaded onto the outer wall of the screw 6. A first bevel gear 8 is fixedly mounted on the outer wall of the nut ring 7. A drive motor 9 is fixed to the top of the storage barrel 5, and a second bevel gear 10 is fixed to the output shaft of the drive motor 9, which meshes with the first bevel gear 8. Driven by the drive motor 9, the first bevel gear 8 and the second bevel gear 10 cooperate to drive the nut ring 7 to rotate, thereby driving the screw 6 up and down. A first bevel ring 14 and a second bevel ring 15 are rotatably connected to the inner wall of the storage barrel 5, with the first bevel ring 14 positioned above the second bevel ring 15. A sealing cylinder 11 is fixed to the top of the stamping plate 12 and is fixedly mounted on the outer wall of the screw 6. The outer diameters of the sealing cylinder 11 and the stamping plate 12 are the same. The inner diameters of the inner circular holes of the first bevel ring 14 and the second bevel ring 15 are the same as the outer diameter of the stamping plate 12. The sealing cylinder 11 and the stamping plate 12 are used to seal the circular holes in the first bevel ring 14 and the second bevel ring 15. When the sealing cylinder 11 is matched with the circular hole in the first bevel ring 14, the raw material above the first bevel ring 14 will be injected between the first bevel ring 14 and the second bevel ring 15.

[0024] Specifically, when the stamping plate 12 closes the discharge port 13, the raw materials in the storage barrel 5 are accumulated downward through the gap between the sealing cylinder 11 and the first bevel ring 14. When the raw materials need to be automatically injected into the mold 4, the drive motor 9 drives the nut ring 7 to rotate, and the screw 6 drives the sealing cylinder 11 and the stamping plate 12 to move upward. When the stamping plate 12 releases the seal on the discharge port 13, the sealing cylinder 11 just blocks the circular hole in the first bevel ring 14. At this time, the raw materials between the first bevel ring 14 and the second bevel ring 15 fall into the mold 4 through the discharge port 13. Then the nut ring 7 rotates in the opposite direction, and the screw 6 drives the sealing cylinder 11 and the stamping plate 12 to move downward until the stamping plate 12 extends into the mold 4 to stamp the raw materials.

[0025] Reference Figure 3-Figure 6 To accelerate the injection of raw materials from the storage barrel 5 into the mold 4, the press also features a stirring mechanism. This stirring mechanism includes a drive shaft 16 that rotates on one side of the storage barrel 5 via a base. The drive shaft 16 is connected to the nut ring 7 via a synchronous pulley and a synchronous belt. A third bevel gear 17 is fixed to the bottom end of the drive shaft 16. A first rotating ring 19 and a second rotating ring 20 are connected to the outer wall of the storage barrel 5, rotating from top to bottom. Multiple connecting rods 21 are fixed between the first and second rotating rings 19, 20, connecting them as a single unit. A bevel gear ring 18, which meshes with the third bevel gear 17, is fixed to the top of the first rotating ring 19. The drive shaft 16 drives the first and second rotating rings 19, 20 to rotate via the bevel gear ring 18 and the third bevel gear 17. Multiple first magnets 22 are fixedly embedded in the inner walls of each of the first and second rotating rings 19, 20. Multiple second magnets 23 are fixedly embedded in the outer walls of each of the first and second bevel rings 14, 15. The adjacent first magnets 22 and second magnets 23 generate a magnetic attraction force, which is used to cause the first rotating ring 19 and the second rotating ring 20 to respectively drive the first bevel ring 14 and the second bevel ring 15 to rotate. A plurality of paddles 24 are fixed to the top of each of the first bevel ring 14 and the second bevel ring 15 for stirring the raw materials in the storage barrel 5.

[0026] Specifically, when the nut ring 7 rotates, the synchronous wheel and synchronous belt drive the transmission shaft 16 to rotate. The transmission shaft 16, through the cooperation of the third bevel gear 17 and the bevel gear ring 18, drives the first rotating ring 19 and the second rotating ring 20 to rotate. The magnetic attraction between the first magnet 22 and the second magnet 23 drives the second rotating ring 20 and the first rotating ring 19 to rotate the first bevel ring 14 and the second bevel ring 15. The paddles 24 on the first bevel ring 14 and the second bevel ring 15 stir the raw materials, thereby accelerating the injection of the raw materials into the mold 4.

[0027] Reference Figure 7 and Figure 8The press is also equipped with a discharge structure, which is arranged on the outer wall of the movable plate 27 and is used to drive the insertion rod 36 to move. The discharge structure includes a mounting sleeve 37 fixedly mounted on the outer wall of the movable plate 27. The mounting sleeve 37 is firmly welded or bolted to the outer wall of the movable plate 27 to ensure stability. On one side of the mounting sleeve 37, multiple springs 38 are fixed, and the other ends of these springs 38 are fixedly connected to the frame 1 by welding or bolting. The function of the spring 38 is to provide elastic force to drive the movable plate 27 to return to its original position after being subjected to force.

[0028] Reference Figure 5 、 Figure 7 and Figure 8 One end of the movable plate 27 extends through the frame 1, and a vertical plate 28 is fixed to its other end. The vertical plate 28 is designed to cooperate with the curved plate 29. Multiple curved plates 29 are provided on the side of the vertical plate 28 near the storage barrel 5, creating a squeeze fit between these curved plates 29 and the vertical plates 28. The curved plates 29 are fixed to the outer wall of the second rotating ring 20. When the second rotating ring 20 rotates, the curved plates 29 are driven to rotate together. The cooperation between the curved plates 29, the vertical plates 28, and the spring 38 realizes the reciprocating movement of the movable plate 27.

[0029] Reference Figure 8 A pin 34 is fixedly mounted on the movable plate 27. Two connecting rods 35 are rotatably mounted on the outer wall of the pin 34, one on each side of the movable plate 27. The bottom ends of the connecting rods 35 are rotatably connected to the top ends of two insertion rods 36, respectively. This design allows the reciprocating movement of the movable plate 27 to drive the insertion rods 36 up and down via the connecting rods 35.

[0030] Reference Figure 2 and Figure 7 Two fixed plates 25 are fixed within the frame 1, located above and below the movable plate 27, respectively. The bottom ends of two insertion rods 36 slide through the lower fixed plates 25, ensuring their stability during movement. The conveyor belt 3 is used to transport fallen ceramics, ensuring they can be transported to the next process.

[0031] Specifically, when the second rotating ring 20 rotates the curved plate 29, the curved plate 29 releases its push on the vertical plate 28. At this point, the movable plate 27 and vertical plate 28 move toward the center under the elastic force of the spring 38. The movement of the movable plate 27 rotates the connecting rod 35 via the pin 34. The connecting rod 35 then pushes the insertion rod 36 into the through-hole 31, pushing the push rod 32 and the sliding plate 30 downward, thereby ejecting the ceramic from the mold 4.

[0032] Reference Figure 8In addition, the discharge structure also includes a sliding plate 30 that is slidably arranged in the mold 4. Two through holes 31 are provided on the side of the mold 4 close to the movable plate 27, and these two through holes 31 cooperate with the insertion rod 36. A push rod 32 is inserted into the through hole 31 through the sliding cross bar, and the insertion rod 36 pushes the push rod 32 after being inserted into the through hole 31. The ends of the two push rods 32 away from the movable plate 27 are fixedly connected to the sliding plate 30, and the movement of the push rod 32 will drive the sliding plate 30 to move. At the same time, the outer walls of the two push rods 32 are both provided with tension springs 33 that are fixedly connected to the sliding plate 30, and the other ends of the tension springs 33 are respectively fixedly connected to the corresponding cross bars. The function of the tension spring 33 is to provide elastic force to drive the sliding plate 30 to reset after being subjected to force.

[0033] Specifically, in actual use, the chain conveyor 2 moves the mold 4 downward, aligning the two molds 4 along the same axis. At this point, the insertion rod 36 is aligned with the push rod 32. When the connecting rod 35 pushes the insertion rod 36 into the through-hole 31, it pushes the push rod 32 and the sliding plate 30 downward, pushing the ceramic out of the mold 4. The pushed ceramic lands on the conveyor belt 3, which then transports it to the next process step.

[0034] Reference Figure 1 and Figure 4 To ensure smooth lifting and lowering of the sealing cylinder 11 and the punching plate 12, a fixed plate 39 is fixed to the top of the sealing cylinder 11. Guide rods 40 are fixed to both sides of the top of the fixed plate 39. The top ends of these two guide rods 40 slide and extend above the storage cylinder 5. The design of the guide rods 40 limits the shaking of the sealing cylinder 11 and the punching plate 12 during the lifting process, ensuring smooth lifting.

[0035] Reference Figure 2 and Figure 7 A support plate 26 is fixed to each side of the two fixed plates 25, facing away from each other. These two support plates 26 are precisely mounted between the two chain conveyors 2, and their position is set to effectively support the mold 4. When the stamping plate 12 is performing a stamping operation, the mold 4 is placed on the support plates 26, ensuring that the mold 4 remains stable during the stamping process without shaking or shifting, thereby ensuring the quality of the high-aluminum ceramic material produced.

[0036] In summary, the press for producing high-aluminum ceramic materials in this embodiment realizes the automatic ejection and transportation of ceramics through a specific discharge structure design, thereby improving production efficiency and the degree of automation.

[0037] Example 2: Reference Figures 9-11, based on the improvement of Example 1: A U-shaped frame 41 is fixed to the top of the press frame 1. A screw 42 is threaded through the U-shaped frame 41. The outer wall of the screw 42 is slidably connected to a rotating cylinder 44 via a sliding groove and a slider. This connection ensures that the rotating cylinder 44 can slide smoothly along the screw 42. At the same time, the rotating cylinder 44 rotates on the top of the U-shaped frame 41, allowing the rotating cylinder 44 to rotate within the U-shaped frame 41.

[0038] refer to Figure 10 and Figure 11 A rotating rod 43 is fixed at the bottom center of the third bevel gear 17. The rotating rod 43 is connected to the rotating cylinder 44 through a synchronous wheel and a synchronous belt. This connection ensures that when the rotating rod 43 rotates, the rotating cylinder 44 can be driven to rotate synchronously.

[0039] refer to Figure 11 The bottom end of the lead screw 42 is fixed with a rotating disk 45, and the outer wall of the rotating disk 45 is fixed with a cotton ring 46. This cotton ring 46 is used to clean the inner wall of the mold 4 and apply lubricant to reduce friction and wear between the ceramic and the mold 4.

[0040] refer to Figure 11 An annular liquid reservoir 48 is fixed to the top inner wall of the U-shaped frame 41. This annular liquid reservoir 48 is used to store lubricant. A plurality of discharge pipes 49 are fixed to the bottom of the annular liquid reservoir 48 and are connected to the annular liquid reservoir 48. The discharge pipes 49 are equipped with solenoid valves to control the dripping of lubricant.

[0041] Specifically, in actual operation, the solenoid valve on the discharge pipe 49 is first opened, causing the lubricant in the annular liquid reservoir 48 to drip onto the truncated cone 47. Then, the rotating rod 43 drives the rotating cylinder 44 via the synchronous wheel and synchronous belt. The rotation of the rotating cylinder 44 drives the lead screw 42 to rotate, thereby allowing the rotating disk 45 and the cotton ring 46 to extend into the mold 4. During this process, the rotation of the truncated cone 47 causes the lubricant on it to smoothly adhere to the cotton ring 46 due to the centrifugal force. The rotation of the cotton ring 46 and its contact with the inner wall of the mold 4 cleans the inner wall of the mold 4 and applies lubricant.

[0042] refer to Figure 11 A frustum 47 is fixed to the top of the rotating disk 45. The frustum 47 is fixedly sleeved on the outer wall of the lead screw 42. The design of the frustum 47 is to enable the lubricant dripping thereon to adhere more smoothly to the cotton ring 46 under the action of centrifugal force.

[0043] Specifically, when the rotating disk 45 and the cotton ring 46 are extended into the mold 4 by the screw 42, the rotation of the frustum 47 causes the lubricant thereon to be thrown out by the centrifugal force and adhere to the cotton ring 46. In this way, when the cotton ring 46 contacts the inner wall of the mold 4, the lubricant is evenly applied to the inner wall of the mold 4, thereby effectively reducing friction and wear between the ceramic and the mold 4.

[0044] A method for using a press for producing high-aluminum ceramic materials comprises the following steps: S1. The mold 4 is transported to the bottom of the storage barrel 5 through the chain conveyor 2. At this time, the stamping plate 12 closes the discharge port 13, and the raw material in the storage barrel 5 accumulates downward through the gap between the sealing cylinder 11 and the first bevel ring 14. When the raw material needs to be automatically injected into the mold 4, the driving motor 9 drives the nut ring 7 to rotate through the cooperation of the first bevel gear 8 and the second bevel gear 10. The nut ring 7 is threadedly connected to the screw rod 6, and the screw rod 6 drives the sealing cylinder 11 and the stamping plate 12 to move upward. When the stamping plate 12 releases the seal on the discharge port 13, the sealing cylinder 11 just blocks the circular hole in the first bevel ring 14. At this time, the raw material between the first bevel ring 14 and the second bevel ring 15 falls into the mold 4 through the discharge port 13; S2. Then the punching plate 12 continues to move upward, the nut ring 7 drives the transmission shaft 16 to rotate through the synchronous wheel and the synchronous belt, and the transmission shaft 16 drives the first rotating ring 19 and the second rotating ring 20 to rotate through the cooperation of the third bevel gear 17 and the bevel gear ring 18. The second rotating ring 20 and the first rotating ring 19 drive the first bevel ring 14 and the second bevel ring 15 to rotate through the magnetic attraction between the first magnet 22 and the second magnet 23. The prying plates 24 on the first bevel ring 14 and the second bevel ring 15 stir the raw materials to accelerate the injection of the raw materials into the mold 4; S3. When it is necessary to punch the raw material in the mold 4, the nut ring 7 rotates in the opposite direction, and the screw 6 drives the sealing cylinder 11 and the punching plate 12 to move downward until the punching plate 12 extends into the mold 4 to punch the raw material, and the fixed plate 25 and the support plate 26 support the mold 4. During punching, the sealing cylinder 11 can block the discharge port 13, and the raw material in the storage barrel 5 can continue to accumulate downward through the circular hole in the first bevel ring 14, which is convenient for subsequent filling of the mold 4; S4. After the stamping is completed, the stamping plate 12 is reset to close the discharge port 13, and the chain conveyor 2 moves the mold 4 downward. Due to the friction between the ceramic and the inner wall of the mold 4, the ceramic is still in the mold 4. When the second rotating ring 20 drives the curved plate 29 to rotate, the curved plate 29 releases the push on the vertical plate 28. The movable plate 27 and the vertical plate 28 move toward the middle under the elastic force of the spring 38. The movable plate 27 drives the connecting rod 35 to rotate through the pin rod 34. The connecting rod 35 pushes the insertion rod 36 to insert into the through hole 31 and pushes the push rod 32 and the sliding plate 30 to move downward, pushing the ceramic in the mold 4 out, and the ceramic just falls on the conveyor belt 3, and the ceramic is transported to the next process; S5. When the chain conveyor belt 2 transports the mold 4 discharged from the ceramic into the U-shaped frame 41, the solenoid valve on the discharge pipe 49 is opened, and the lubricant in the annular liquid storage cylinder 48 drips onto the frustum 47. The rotating rod 43 drives the rotating cylinder 44 to rotate through the synchronous wheel and the synchronous belt. The rotating cylinder 44 drives the screw 42 to rotate. The rotation of the screw 42 drives the rotating disk 45 and the cotton ring 46 to extend into the mold 4. When the frustum 47 rotates, the lubricating oil on it adheres to the cotton ring 46 under the action of centrifugal force. The inner wall of the mold 4 can be cleaned and lubricated through the cotton ring 46, reducing the friction and wear between the ceramic and the mold 4.

Those skilled in the art can make any selection according to their needs or convenience.
