[0040] The working principle of the shaping mechanical equipment for manufacturing and processing ceramic products provided by the present invention is as follows:

[0041] When a ceramic craftsman uses this device to shape a clay blank, he can first place the clay blank to be shaped on the suction cup 10, fit the suction cup 10 at the bottom of the clay blank, and then press the controller on the mounting shell 9 to start the vacuum pump 11 and open the electromagnetic valve 32 on the first connecting pipe 12. When the vacuum pump 11 is running, it cooperates with the first connecting pipe 12 and the exhaust pipe 13 to extract and discharge the air in the suction cup 10. After the air is discharged, the suction cup 10 will firmly adhere to the bottom of the clay blank, so that the clay blank can be placed and fixed, which can prevent the clay blank from falling and being damaged during the rotation shaping process. After the clay blank is fixed, the craftsman can control the speed regulator to start the motor 6. The output shaft of the running motor 6 will drive the rotating shaft 8 to rotate, and the mounting shell 9 and the suction cup 10 will absorb the fixed clay. The blank also rotates accordingly, and then the dust suction fan 18 is turned on, and then the ceramic craftsman can use the tool to rotate the rotating clay blank to shape it. The clay blank can be rotated by this simple operation, which can effectively reduce the labor of the personnel. During the shaping of the rotating pin, under the action of the running dust suction fan 18, the mud dust generated during the shaping of the rotating pin will be absorbed along the dust collecting cover on the dust collecting pipe 21 and enter the dust collecting pipe 21, and then the mud dust will fall into the dust filter bag 17 along the telescopic pipe 22 to absorb and collect the mud dust, which can prevent the mud dust from floating around and affecting the working environment. The mud blocks dropped by the rotating pin outside the clay blank will fall into the through groove 4, and then the mud blocks will fall into the collection box 24 along the connecting pipe 25. The collected mud dust and mud blocks can be reused, which can reduce waste.

[0042] According to actual needs, the craftsman can operate the speed regulator to flexibly adjust the speed of the motor 6, and the tools used can be placed on the storage plate 27 for easy access. During the shaping period, when the light is dim and the visibility is poor, the personnel can turn on the lighting lamp 31 to provide lighting. After the shaping is completed, the motor 6 is first turned off, and then the electromagnetic valve 32 on the intake pipe 14 is opened, and then the shaped mud embryo can be removed from the suction cup 10; the storage plate 27 can be flipped and folded. When cleaning the table top of the operating table 1, the personnel can flip the storage plate 27, and the top of the support block 28 is separated from the limiting groove at the bottom of the storage plate 27, and the magnet on the top of the storage plate 27 can be attracted to the magnet block on one side of the shielding cover 2, which can limit the storage plate 27. After that, the personnel pulls out the support block 28 from the limiting groove on the top of the operating table 1, and then puts it into the storage groove opened on the top of the operating table 1.

After the air is discharged, the suction cup 10 can firmly adsorb the bottom of the clay blank, and the clay blank can be placed and fixed to avoid the clay blank from falling and being damaged during the rotation shaping process. The dust collection mechanism is set to absorb and collect the dust. , which can prevent mud and dust from flying around and affecting the working environment.
