[0033] First, set up the device next to the glaze spraying machine, and make the conveying component 2 correspond to the specified position, start the conveying component 2 to rotate forward, when a part of the ceramic toilet is glazed and the bottom is not glazed, the glaze sprayed on the ceramic toilet is dried, and then the conveying machine conveys the ceramic toilet to the conveying component 2, and the conveying component 2 rotates forward to drive the ceramic toilet to move to the right. When the ceramic toilet moves to the right to just below the front and rear clamping blocks 6, close the conveying component 2, start the electric lifting plate 4 to move downward to drive the return plate 41 to move downward, and the return plate 41 moves downward to drive the movable plate 43 to move downward. The movable plate 43 drives the clamping block 6 to move downward through the U-shaped rod 5. When the clamping block 6 moves downward to the front and rear sides of the ceramic toilet, close the electric lifting plate 4, start the electric screw 44 to rotate forward, and the electric The screw 44 rotates forward to drive the front and rear movable plates 43 to move towards each other, and the movable plates 43 drive the front and rear clamping blocks 6 to move towards each other through the U-shaped rod 5. The front and rear clamping blocks 6 move and contact the ceramic toilet. The electric screw 44 is turned off, and the front and rear clamping blocks 6 stop moving. Then the oil pump 8 is started, and the oil pump 8 discharges the hydraulic oil into the telescopic bag 81. The hydraulic oil in the telescopic bag 81 is discharged into the hydraulic valve 91. Since the pressure has not reached the pressure value set by the hydraulic valve 91, the discharge of the hydraulic oil first causes the telescopic bag 81 to expand and extend. The expansion and extension of the telescopic bag 81 drives the clamping block 6 close to the U-shaped rod 5 to swing first and contact closely with the ceramic toilet, so that the clamping block 6 can adapt to the curved or flat outer wall of the ceramic toilet for clamping and fixing. Then the pressure value reaches When the pressure reaches the set pressure value of the hydraulic valve 91, the hydraulic oil is discharged into the inner single-rod arc cylinder body 7 through the hydraulic valve 91, so that the piston rod of the inner single-rod arc cylinder body 7 is extended to drive each group of middle clamping blocks 6 to swing inward, so that the swing of each group of middle clamping blocks 6 can adapt to the outer wall of the ceramic toilet for clamping and fixing. Then, after each group of middle clamping blocks 6 clamps the ceramic toilet, each group of middle clamping blocks 6 stops swinging so that the piston rod of the inner single-rod arc cylinder body 7 stops moving. Then, the hydraulic oil in the inner single-rod arc cylinder body 7 is discharged into the outer single-rod arc cylinder body 7 through the connecting pipe 11, which also makes the piston rod in the outer single-rod arc cylinder body 7 extend. The extension of the piston rod in the outer single-rod arc cylinder body 7 drives the outer clamping block 6 to swing inward, and the outer clamping block 6 swings inward to adapt to the outer wall of the ceramic toilet. The outer wall of the ceramic toilet is clamped and fixed, and this is repeated, so that the clamp block 6 can swing in turn and clamp the ceramic toilet tightly and fix it, which can adapt to the curved and flat outer wall of the ceramic toilet, so as to clamp and fix ceramic toilets of different sizes. Then, the oil pump 8 is turned off, and the hydraulic oil stops being discharged into the telescopic bag 81, and the clamp block 6 stops swinging. At this time, the ceramic toilet is clamped and fixed by the clamp block 6, and the electric lifting plate 4 can be started to drive the return plate 41 to move upward, and the return plate 41 drives the movable plate 43 to move upward. The movable plate 43 drives the clamp block 6 to move upward through the U-shaped rod 5, and the clamp block 6 drives the ceramic toilet to move upward and disengage from the conveying component 2. When the clamp block 6 moves upward and resets, the electric lifting plate 4 is turned off, and the drive motor 42 is started to drive the return plate 41 to rotate 180 degrees.The return plate 41 drives the movable plate 43 to rotate, and the movable plate 43 drives the clamping block 6 to rotate through the U-shaped rod 5, and the clamping block 6 drives the ceramic toilet to rotate 180 degrees to flip over. When the ceramic toilet is flipped over, the drive motor 42 is turned off, the return plate 41 stops rotating, the clamping block 6 stops driving the ceramic toilet to rotate, and the electric lifting plate 4 is started to drive the return plate 41 to move downward, so that the clamping block 6 drives the ceramic toilet to move downward and reset to contact with the conveying component 2, the electric lifting plate 4 is turned off, and the oil pump 8 is started to pump back the hydraulic oil in the telescopic bag 81, and also through the one-way valve 9 Draw back the hydraulic oil in the single-rod arc cylinder 7. As the hydraulic oil is drawn back, the piston rod in the single-rod arc cylinder 7 contracts and resets, driving the clamp block 6 to swing outward and reset. Turn off the oil pump 8, then start the electric screw 44 to reverse and drive the front and rear movable plates 43 to move away from each other and reset. The movable plates 43 drive the clamp block 6 to move and reset through the U-shaped rod 5. The clamp block 6 resets to release the ceramic toilet, start the electric lifting plate 4 to move upward and reset, then start the conveying assembly 2 to reverse and drive the flipped ceramic toilet to move to the designated position to complete the full glazing. In this way, through the swing of the clamp block 6, ceramic toilets of different sizes can be clamped and fixed for flipping, thereby improving adaptability; Protection of ceramic toilet: When the clamp block 6 drives the ceramic toilet to move upward, the electric push rod 126 is started, and the telescopic rod of the electric push rod 126 extends to drive the swing block 125 to swing downward, and the swing block 125 swings downward to drive the shaft 12 to rotate, and the rear shaft 12 drives the rear mounting block 121 to reverse, and the rear mounting block 121 reverses to drive the fixed cylinder 124 to swing downward ninety degrees. At the same time, the front shaft 12 drives the front mounting block 121 to rotate forward, and the front mounting block 121 rotates forward to drive the plug rod 122 to rotate forward ninety degrees, and the plug rod 122 rotates forward. Ninety degrees corresponds to the fixed cylinder 124, the insertion rod 122 and the front mounting block 121 rotate forward to drive the protective net 123 to rotate forward ninety degrees, the electric push rod 126 is closed, and the electric rotating rod 127 is started to reverse and drive the spur gear 128 to reverse, the spur gear 128 reverses and drives the insertion rod 122 to move backward through the tooth groove 129, the insertion rod 122 moves backward and drives the protective net 123 to move backward and unfold, as the insertion rod 122 continues to move backward, the insertion rod 122 moves backward and is inserted into the fixed cylinder 124, the electric rotating rod 127 is closed, and the spur gear 128 stops The tooth groove 129 drives the plug rod 122 to move backward, and the plug rod 122 cooperates with the fixing cylinder 124 to fix the protection net 123. When the clamp block 6 drives the ceramic toilet to flip, the protection net 123 protects the rotating ceramic toilet to prevent the ceramic toilet from falling to the ground and causing damage, thereby ensuring the safety of the ceramic toilet during rotation. When the ceramic toilet is flipped, the electric rotating rod 127 is started to rotate forward to drive the spur gear 128 to rotate forward. The spur gear 128 rotates forward through the tooth groove 129 to drive the plug rod 122 to move forward and reset. The rod 122 is reset and disengaged from the fixed cylinder 124, and the insertion rod 122 moves forward to reset, driving the protective net 123 to move forward to reset and fold. The folded protective net 123 does not affect the downward movement of the ceramic toilet. The electric push rod 126 is started again to drive the swing block 125 to swing upward and reset, which makes the rear mounting block 121 rotate forward and drive the fixed cylinder 124 to swing upward ninety degrees to reset. The front mounting block 121 reverses and drives the insertion rod 122 to reverse ninety degrees to reset. The insertion rod 122 and the front mounting block 121 drive the protective net 123 to reverse ninety degrees to reset.

[0035] When the conveying assembly 2 rotates forward and drives the ceramic toilet to move to the right to just below the front and rear clamping blocks 6, the ceramic toilet moves to the right and contacts the protection pad 135. The protection pad 135 provides buffer protection for the ceramic toilet to prevent the ceramic toilet from violently contacting the straight-line orifice plate 133 and causing damage, thereby ensuring the safety of the contact between the ceramic toilet and the straight-line orifice plate 133. The conveying assembly 2 is closed, and the ceramic toilet is between the front and rear positioning rods 134. The electric screw 1341 is started to rotate forward and drive the front and rear positioning rods 134 to move toward each other. The front and rear positioning rods 134 move and contact the ceramic toilet. The front and rear positioning rods 134 center the ceramic toilet, and then the electric screw 1341 is started again to reverse and drive the front and rear positioning rods 134 to move away from each other The cylinder 1342 is reset by moving in the direction away from the ceramic toilet, and the positioning rod 134 is reset and disengaged from the ceramic toilet. The cylinder 1342 is started again, and the telescopic rod of the cylinder 1342 is shortened to drive the fixed frame 132 to move right. The fixed frame 132 moves right and drives the straight orifice plate 133 to move right. The straight orifice plate 133 drives the positioning rod 134 to move right to the upper right side of the conveying component 2, and the cylinder 1342 is closed. The electric rotating block 131 is started to rotate forward ninety degrees to drive the cylinder 1342 to rotate forward ninety degrees. The cylinder 1342 drives the straight orifice plate 133 to swing upward ninety degrees through the fixed frame 132. The straight orifice plate 133 drives the positioning rod 134 to swing upward ninety degrees. The positioning rod 134 swings upward and leaves the moving area of ​​the ceramic toilet, so that the positioning rod 134 does not affect the movement of the ceramic toilet. When the ceramic toilet bowl is flipped and moved to the conveying assembly 2, the conveying assembly 2 is reversed to drive the ceramic toilet bowl to move to the left for subsequent full glazing, and at the same time, the electric rotating block 131 is reversed to drive the cylinder 1342 to reverse 90 degrees to reset, and the cylinder 1342 drives the straight hole plate 133 to swing downward to reset through the fixed frame 132, and the straight hole plate 133 drives the positioning rod 134 to swing downward to reset, and then the cylinder 1342 is started to drive the fixed frame 132 to move to the left to reset, and the fixed frame 132 drives the positioning rod 134 to move to the left to reset through the straight hole plate 133.

In this way, the ceramic toilet can be prevented from violently contacting the conveying assembly 2 when moving downward and causing damage, thereby further ensuring the safety of the ceramic toilet.
