[0013] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0014] (1) A locking component and a protection component are arranged on the support assembly. The sucker device moves the inverted ceramic blank above the support assembly, presses the ceramic blank onto the sliding block, presses the sliding block into the sliding cavity, the sliding block squeezes the air in the sliding cavity into the air outlet groove, and the air in the air outlet groove is discharged from the exhaust hole and blown onto the ceramic blank to blow off the dust on the outer surface of the ceramic blank, preventing dust from remaining on the surface of the ceramic blank and affecting the subsequent process. When the sliding block enters the sliding cavity, the sliding block squeezes the inclined surface of the locking block, causing the locking block to be squeezed into the connection groove. The locking block is no longer below the sliding block. After the sliding block continues to descend, the sliding block is lower than the height of the locking block. The small spring pushes the sliding vertical rod to move, and the sliding vertical rod pushes the locking block to reset and block above the sliding block. At this time, the sliding block is blocked above by the locking block, so that the ceramic blank is located in the sliding cavity and the ceramic blank is protected in the sliding cavity;

[0015] (2) The sliding block drives the sliding column to descend through the connecting cross bar. The sliding column drives the screw rod to rotate through the spiral groove. The screw rod drives the semi-circular plate to rotate in the installation groove. The screw rod drives the rotating circular plate to rotate 180 degrees and block above the sliding cavity, preventing the air pump from malfunctioning and the sucker from separating from the ceramic blank, resulting in the ceramic blank falling off and breaking. After the ceramic blank is fixed, the driving motor drives the driven gear to rotate through the driving gear, and the rotating plate drives the fixing mechanism and the ceramic blank to flip 180 degrees, so that the ceramic blank is flipped from the inverted state. When the reverse rotation is completed, the opening of the sliding cavity faces the reverse direction. The pressing plate contacts the transmission device and is squeezed. The pressing plate drives the pressing rod and the triangular block to slide into the installation cavity. The triangular block squeezes the inclined surface, causing the sliding vertical rod to move away from the sliding cavity. The sliding vertical rod drives the locking block to move, and the locking block moves away from below the sliding block. At this time, the large spring pushes the sliding block to move out of the sliding cavity, and the sliding block drives the connecting cross bar to move. The spiral groove drives the rotating circular plate to reset through the screw rod and move away from above the sliding cavity. The air pump controls the sucker to stop adsorbing the ceramic blank, and the ceramic blank falls on the transmission device to continue the subsequent process. Description of the Drawings

When the sliding block 241 slides into the sliding cavity 214, the air in the sliding cavity 214 is squeezed and injected into the fixing ring 215 from the air outlet groove 218 and the air duct 219, and then discharged from the exhaust hole 216 to blow and clean the surface of the ceramic blank, preventing the ceramic blank from being contaminated with dust on the conveying device and affecting the subsequent processes.

[0036] The rotating mechanism 1 includes a fixed block 11. A driving motor is arranged inside the fixed block 11. The output end of the driving motor penetrates through the fixed block 11 and is fixedly connected with a driving gear 12. A rotating plate 14 is rotatably connected above the fixed block 11. A driven gear 13 is fixedly connected to one side of the rotating plate 14. The driving gear 12 is meshed with the driven gear 13.

The connecting holes 16 correspond to the round holes on the sliding cavity 214. The fixed seat 211 is fixedly connected to the upper end of the rotating plate 14. The connecting hose below the vertical rod 243 is connected with an air pump through the connecting hole 16 and the installation hole 15.

[0037] The working principle and usage process of the present invention: During use, the inverted ceramic blank is moved above the support assembly 21 through a suction cup device. The ceramic blank is pressed down onto the sliding block 241, and the sliding block 241 is pressed into the sliding cavity 214. The sliding block 241 moves downward, squeezing the air in the sliding cavity 214 into the air outlet groove 218. The air in the air outlet groove 218 enters the fixed ring 215 through the air duct 219. The air flow in the fixed ring 215 is discharged through the exhaust holes 216, blowing on the ceramic blank to blow off the dust on the outer surface of the ceramic blank, preventing dust from remaining on the surface of the ceramic blank and affecting subsequent processes. When the sliding block 241 enters the sliding cavity 214, the sliding block 241 squeezes the inclined surface of the locking block 225, causing the locking block 225 to be squeezed into the connecting groove 217. At this time, the locking block 225 is no longer below the sliding block 241. When the sliding block 241 continues to descend, the sliding block 241 is lower than the height of the locking block 225. The small spring 223 pushes the sliding vertical rod 221 to move, and the sliding vertical rod 221 pushes the locking block 225 to reset, blocking above the sliding block 241. The suction cup device stops pressing and separates from the ceramic blank. At this time, the sliding block 241 is blocked above by the locking block 225 and cannot be pushed back by the large spring 244, keeping the ceramic blank in the sliding cavity and protecting the ceramic blank in the sliding cavity 214.

[0038] When the sliding block 241 descends, it drives the ceramic blank into the sliding cavity 214. The sliding block 241 drives the sliding column 251 to descend through the connecting cross bar 252. The sliding column 251 drives the spiral rod 232 to rotate through the spiral groove 253. The spiral rod 232 drives the semi-circular plate 233 to rotate in the installation groove 212. The spiral rod 232 drives the rotating circular plate 231 to rotate 180 degrees, blocking above the sliding cavity 214 to prevent the air pump from malfunctioning and the suction cup 242 from separating from the ceramic blank, resulting in the ceramic blank falling off and breaking.

[0039] After the ceramic blank is fixed, the driving motor drives the driving gear 12 to rotate. The driving gear 12 drives the driven gear 13 to rotate, and the driven gear 13 drives the rotating plate 14 to rotate. The rotating plate 14 drives the fixing mechanism 2 and the ceramic blank to be flipped by 180 degrees, so that the ceramic blank is flipped from the inverted state. After the reverse rotation is completed, the opening of the sliding cavity 214 faces the reverse direction. The extrusion plate 228 contacts the transmission device and is extruded. The extrusion plate 228 drives the extrusion rod 226 and the triangular block 227 to slide into the installation cavity 213. The triangular block 227 extrudes the inclined surface 224, causing the sliding vertical rod 221 to move away from the sliding cavity 214. The sliding vertical rod 221 drives the locking block 225 to move, and the locking block 225 moves away from below the sliding block 241. At this time, the large spring 244 pushes the sliding block 241 to move out of the sliding cavity 214, and the sliding block 241 drives the connecting cross bar 252 to move. The spiral groove 253 drives the rotating circular plate 231 to reset through the spiral rod 232 and moves away from above the sliding cavity 214. The air pump controls the suction cup 242 to stop adsorbing the ceramic blank, and the ceramic blank falls on the transmission device to continue the subsequent process.

[0040] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
