[0022] Specifically, the first lifting mechanism 4 includes a second electric telescopic rod 401 and a support plate 402. The second electric telescopic rod 401 is fixedly installed on the upper inner wall of the workbench 1, and the support plate 402 is fixedly installed on the upper surface of the second electric telescopic rod 401. The second lifting mechanism 14 has the same structure as the first lifting mechanism 4.

[0027] In this embodiment, the moving plate 801 drives the pressure sensor 802 to move downward, and the pressure sensor 802 drives the mounting plate 9 to move downward, causing the mounting plate 9 to drive the pressing plate 12 to move downward through the motor 10 and the rotating shaft 11, enabling the reverse upward pressure of the pressing plate 12 to be monitored, that is, the pressure of the pressing plate 12 is monitored, and the information is fed back to the controller 803. The display screen on the controller 803 shows the information. When the pressure is greater than or less than the set value, the controller 803 causes the alarm 804 to alarm, reminding the staff to perform maintenance in a timely manner.

[0028] Specifically, the cloth feeding mechanism 13 includes a fixing plate 131, a spring 132, a cross plate 133, rake teeth 134, and through holes 135. The fixing plate 131 is fixedly installed on the rotating shaft 11. The lower surface of the fixing plate 131 is provided with a cross plate 133 through a spring 132. The lower surface of the cross plate 133 is evenly provided with rake teeth 134. Through holes 135 are provided on the pressing plate 12 corresponding to the rake teeth 134, and the rake teeth 134 are inserted under the lower surface of the pressing plate 12 through the through holes 135.

[0029] In this implementation scheme, the fixed plate 131 rotates with the rotating shaft 11, causing the fixed plate 131 to drive the cross plate 133 to rotate through the spring 132, and the cross plate 133 drives the rake teeth 134 to rotate, stirring the raw materials in the disc 2 to make the raw materials in the disc 2 evenly distributed.

[0030] Specifically, third through holes 17 are respectively formed in the top plate 6 at positions corresponding to the first electric telescopic rod 7 and the motor 10, and a fourth through hole 18 is formed in the moving plate 801 at a position corresponding to the motor 10.

[0032] Specifically, a fifth through hole 19 is formed in the mounting plate 9 corresponding to the rotating shaft 11, and a sixth through hole 20 is formed in the cross plate 133 corresponding to the rotating shaft 11.

[0033] In this implementation scheme, the fifth through hole 19 meets the requirement for the installation and rotation of the rotating shaft 11 in the mounting plate 9, and the sixth through hole 20 meets the requirement for the installation and rotation of the rotating shaft 11 on the cross plate 133.

[0034] During use, pour the corresponding ceramic grinding wheel raw materials into the disc 2. At this time, the first electric telescopic rod 7 drives the pressure detection mechanism 8 to move downward. The pressure detection mechanism 8 drives the motor 10 to move downward through the mounting plate 9, so that the motor 10 drives the pressing plate 12 downward through the rotating shaft 11.

The output shaft of the motor 10 drives the rotating shaft 11 to rotate, and the fixing plate 131 rotates with the rotating shaft 11, so that the fixing plate 131 drives the cross plate 133 to rotate through the spring 132. The cross plate 133 drives the rake teeth 134 to rotate, stirring the raw materials in the disc 2 to make the raw materials in the disc 2 evenly distributed. After cloth feeding, the second lifting mechanism 14 jacks up the cross plate 133 upward. The cross plate 133 drives the rake teeth 134 to move upward, making the lower surface of the rake teeth 134 flush with the lower surface of the pressing plate 12. The pressing plate 12 continues to press downward, and the pressing plate 12 presses and forms the ceramic grinding wheel raw materials on the upper surface of the mold 3 in the disc 2. During the pressing and forming process, the moving plate 801 drives the pressure sensor 802 to move downward. The pressure sensor 802 drives the mounting plate 9 to move downward, so that the mounting plate 9 drives the pressing plate 12 to move downward through the motor 10 and the rotating shaft 11, capable of monitoring the reverse upward pressure of the pressing plate 12, that is, monitoring the pressure of the pressing plate 12 and feeding back the information to the controller 803. The display screen on the controller 803 displays it. When the pressure is greater than or less than the set value, the controller 803 makes the alarm 804 alarm, reminding the staff to repair in time. After the ceramic grinding wheel is pressed and formed, the pressing plate 12 resets. The piston of the second electric telescopic rod 401 in the first lifting mechanism 4 drives the support plate 402 to move upward, so that the support plate 402 drives the mold 3 and the disc 2 to move upward, and the support plate 402 drives the formed grinding wheel in the disc 2 to move upward, facilitating the removal of the grinding wheel.
