The turntable 11 can rotate the stamped ceramic sheet to the top of the baffle 15 and rotate the adjacent forming die 27 to the bottom of the stamping die 9 to facilitate the next stamping, improve the stamping efficiency, and solve the existing problem of not being able to load and discharge materials simultaneously. The rubber scraper 24 can simply clean the end surface of the turntable 11.

[0031] A main body 1 is provided above the installation bin 2, and a plurality of positioning rods 3 are connected between the installation bin 2 and the main body 1. The outer portion of the positioning rods 3 is slidably connected to a stamping disc 7. A hydraulic press 6 is provided above the stamping disc 7 at the bottom of the main body 1, and the output end of the hydraulic press 6 is connected to the end face of the stamping disc 7. The hydraulic press 6 is a prior art and will not be elaborated in detail herein. Its main function is to provide power for stamping. The toggle assembly includes a crank 23, and the feeding mechanism includes a plurality of feeding dies 8 provided at the bottom of the stamping disc 7. A storage box 4 is provided above the feeding die 8 on the end face of the main body 1, and a feeding pipe 5 is provided between the storage box 4 and the feeding die 8. The feeding pipe 5 on the side surface of the storage box 4 can continuously provide raw materials to the forming die 27 through the feeding die 8, thereby realizing automatic feeding and making the work process more convenient.

[0032] Each baffle 15 has a through hole 29 on the end surface of the load-bearing plate 14. A slider 19 is slidably mounted below the through hole 29. The slider 19 is sloped, and a wheel frame 30 is mounted above the slider 19. A roller 18 is rotatably mounted inside the wheel frame 30, and the roller 18 and the slider 19 abut against each other. A support rod 16 is connected between the wheel frame 30 and the baffle 15, and a return spring 17 is mounted on the outside of the support rod 16. The return spring 17 can keep the roller 18 in close contact with the slider 19, preventing the roller 18 from becoming disconnected from the slider 19, and can also reduce vibration of the roller 18 during movement, making the device more stable.

[0033] refer to Figure 7-8 A slide rail 20 is provided below the slider 19 on the bottom end surface of the mounting chamber 2. The slide rail 20 and the slider 19 are connected to each other, and a connecting rod 21 is provided between the multiple sliders 19. The connecting rod 21 enables the sliders 19 on both sides to operate synchronously. A cylinder 22 is provided on one side of the connecting rod 21 at the bottom of the mounting chamber 2, and the output end of the cylinder 22 is connected to the connecting rod 21.

[0034] A driving motor 26 is provided inside the installation chamber 2, and a crank 23 is connected to the output end of the driving motor 26. A stopper 25 is provided outside the crank 23. Two doors 10 are hingedly provided on one side of the installation chamber 2. There are two cranks 23.

[0035] When the device is running, the staff adds material to the storage box 4, and the storage box 4 transports the ceramic powder to the inside of the feeding die 8 through the feeding pipe 5, and starts the hydraulic press 6, which pushes the punching plate 7. The punching plate 7 drives the punching die 9 and the feeding die 8 along the positioning rod 3. After the feeding die 8 reaches the turntable 11;

[0036] The feeding die 8 feeds the through slot 13. After the feeding is completed, the punching plate 7 is raised, and the stepper motor 12 is started. The stepper motor 12 drives the turntable 11 to rotate. The turntable 11 rotates the through slot 13 with ceramic powder to the bottom of the punching die 9. The punching plate 7 is lowered, driving the punching die 9 to move toward the bearing plate 14 to punch the ceramic powder. While punching, the feeding die 8 feeds the adjacent through slots 13. After the punching and feeding are completed;

[0037] The stamping disc 7 is raised, and the stepper motor 12 rotates again. After the stamped ceramic piece is rotated to the top of the baffle 15, the stamping disc 7 lowers the stamping, and the cylinder 22 is started. The cylinder 22 pushes the connecting rod 21, and the connecting rod 21 pushes the slider 19. The slider 19 moves along the slide rail 20, and the slider 19 lifts the roller 18. The roller 18 drives the support rod 16 to rise along the inclined surface of the slider 19, and the support rod 16 drives the baffle 15 to rise. After the baffle 15 pushes the ceramic piece out of the through groove 13, the drive motor 26 is started, and the drive motor 26 drives the crank 23 to rotate. The crank 23 rotates with the drive motor 26 as the axis to push the ceramic piece out of the through groove 13, and the stepper motor 12 rotates. In this reciprocating manner, loading, stamping, and discharging are carried out simultaneously, thereby improving work efficiency, and avoiding direct contact between the stamping die 9 and the lifting mechanism, thereby improving the service life of the device.

[0038] Example 2:

[0039] As a further example, refer to Figure 6 A vibrator 28 is disposed within the support rod 16, with the output end of the vibrator 28 abutting against the end surface of the baffle 15. Two vibrators 28 are provided, both disposed within the support rod 16. The vibrators 28 vibrate during ejection of the formed ceramic sheet, allowing the formed ceramic sheet to separate from the inner wall of the forming mold 27. This resolves the issue of the ceramic sheet adhering to the forming mold 27 and being unable to be fully removed, thereby improving the stamping quality of the formed ceramic sheet.

[0040] During discharge, the vibrator 28 is started so that when the support rod 16 moves upward, the vibrator 28 can vibrate the baffle 15, and the baffle 15 will transmit the vibration to the ceramic part, so that the contact friction between the ceramic part and the through groove 13 is reduced, and the two are relatively loose, thereby preventing the ceramic part from adhering to the inner wall of the through groove 13 after the stamping is completed, reducing the damage of the ceramic part when it is pushed upward, and improving the discharge effect.

[0041] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction.
