[0034] like Figure 1 and Fig. 9 As shown, a material pushing mechanism 12 is provided on one side of the frame 1, and the material pushing mechanism 12 includes: a transmission plate 121, which is arranged on one side of the lower part of the frame 1; a belt conveyor 122, which is installed on the transmission plate 121, and the conveyor belt of the belt conveyor 122 is flush with the transmission plate 121, and the belt conveyor 122 is used to intermittently transport the toilet blank 100 to be polished; a multi-stage push rod 123, which is fixedly installed on the transmission plate 121, and a push plate 124 is fixedly installed on the push rod of the multi-stage push rod 123, and the push plate 124 faces the placement table 3; a transmission roller 13, which is provided with a plurality of parallel rotating rollers. It is dynamically arranged on the transmission plate 121, and the transmission roller 13 is located between the placement table 3 and the belt conveyor 122. The transmission roller 13 cooperates with the multi-stage push rod 123 to push the material, thereby reducing the wear and tear during the transfer of the toilet blank 100 on the belt conveyor 122 to the placement table 3; the limit block 11, three limit blocks 11 are provided on the edge of the raised table surface of the placement table 3 away from the push plate 124. The limit block 11 is used to accurately limit the toilet blank 100 pushed from the transmission plate 121 to the placement table 3, so as to avoid the toilet blank 100 being placed off-center on the placement table 3 and affecting the subsequent grinding.

[0035] When the device is used to grind the outer wall of the unsintered ceramic toilet blank 100, the toilet blank 100 to be polished is conveyed to the transmission plate 121 by the belt conveyor 122, and then the belt conveyor 122 is shut down and the multi-stage push rod 123 is activated, the telescopic rod of the multi-stage push rod 123 is extended and the toilet blank 100 on the belt conveyor 122 is pushed through the push plate 124, so that the toilet blank 100 on the belt conveyor 122 slides to the transmission roller 13 of the transmission plate 121, and under the rolling conveyance of the transmission roller 13, the toilet blank 100 is smoothly transferred from the transmission plate 121 to the placement table 3 after passing through the tooth groove annular block 31, and is accurately positioned by the three limit blocks 11 on the edge of the placement table 3, ensuring that the toilet blank 100 on the placement table 3 It will not be put off-center and is ready for the next polishing work. After the multi-stage push rod 123 drives the push plate 124 to push the toilet blank 100 to the placement table 3, it will reset and retract onto the belt conveyor 122 and prepare to push the next toilet blank 100. Once the toilet blank 100 is correctly placed on the middle table of the placement table 3, the air pump 5 is enabled and the air is inflated to the connecting head 51 of the air bag 46 through the air guide tube 53. When the air bag 46 is filled with a sufficient amount of gas, the air pump 5 is turned off and the air pressure inside the air bag 46 is maintained at a constant value, and then the cylinder 45 is enabled. The piston rod of the cylinder 45 will extend and push the support plate 44 to rotate toward the toilet blank 100. At this time, the polishing cloth 47 of the air bag 46 at the support plate 44 will rotate to fit and squeeze on the toilet blank. 100, at this time, the pressure sensor 52 is activated and starts to monitor the air pressure in the airbag 46. As the airbag 46 continues to squeeze the outer wall of the toilet blank 100, until the pressure sensor 52 detects that the air pressure in the airbag 46 reaches the preset grinding pressure, the pressure sensor 52 controls the action of the cylinder 45 to stop through the built-in controller, so that the grinding cloth 47 on the airbag 46 is tightly attached to the current outer wall curved surface of the toilet blank 100, and then the first motor 6 is activated, and the output shaft of the first motor 6 drives the gear ring 42 to rotate. At this time, the teeth on the gear ring 42 will rotate and mesh with the teeth of the tooth groove annular block 31, so that the gear ring 42 rolls between the placement table 3 and the tooth groove annular block 31, and the limit of the guide groove 32 at the tooth groove annular block 31 and the placement table 3 Under the position guidance, the guide block 1 411 and the guide block 2 412 on the mounting block 41 can only slide along the corresponding guide groove 32. At the same time, the slide bar 61 on the first motor 6 will slide under the limiting guidance of the annular groove 33, so that the gear ring 42 will drive the mounting block 41 to make a circular motion in the sliding mouth between the placement table 3 and the tooth groove annular block 31, so that the airbag 46 and the grinding cloth 47 on the mounting block 41 are always facing the outer wall of the toilet blank 100 and sliding and grinding. When the grinding cloth 47 on the airbag 46 slides and grinds on the irregular curved surface of the toilet blank 100, the air pressure inside the airbag 46 will change dynamically. At this time, the pressure sensor 52 will monitor the pressure change in the airbag 46 in real time. When the air pressure inside the airbag 46 becomes smaller,The pressure sensor 52 controls the piston rod of the air cylinder 45 to extend and push the support plate 44 through the built-in controller, so that the sanding cloth 47 on the airbag 46 increases the pressure applied to the toilet blank 100. When the air pressure inside the airbag 46 increases, the pressure sensor 52 controls the piston rod of the air cylinder 45 to shorten and pull back the support plate 44 through the built-in controller, so that the sanding cloth 47 on the airbag 46 reduces the pressure applied to the toilet blank 100. Therefore, no matter how the shape of the outer wall of the toilet blank 100 changes, the sanding cloth 47 on the airbag 46 can fit the surface tightly, provide a uniform and effective sanding effect, and ensure the consistency and quality of the sanding of the toilet blank 100.

When the sandblasting tube 8 is lowered into the drainage pipe of the flushing tank of the toilet blank 100, the rubber wheel 92 outside the sleeve 91 contacts and slides into the drainage pipe of the toilet blank 100, and cooperates with the spring 93 to provide a certain supporting force, so that the nozzle of the sandblasting tube 8 can stably slide and sandblast in the drainage pipe of the toilet blank 100.

[0039] When the flushing trough and drainage pipe of the toilet blank 100 are polished, the electric push rod 71 drives the entire mounting frame 72 to move downward until the buffer block 10 on the cover plate 74 is sealed against the top surface of the flushing groove of the toilet blank 100, thereby avoiding damage caused by direct physical contact of the cover plate 74 with the toilet blank 100. At this time, the sandblasting tube 8 and the bifurcated tube 82 located under the cover plate 74 enter the drainage pipe and flushing trough of the toilet blank 100 respectively. Since the sandblasting tube 8 has a certain flexibility and plasticity, it can be smoothly inserted into the toilet When the sandblasting tube 8 is lowered into the drainage pipe, the four rubber wheels 92 on the outer side of the tube wall of the sandblasting tube 8 will contact the inner wall of the drainage pipe and rotate, and the supporting force provided by the spring 93 allows the sandblasting tube 8 to slide stably in the drainage pipe without deviation, and then the extraction pump 76 is activated, and the extraction pump 76 extracts sandblasting abrasives such as glass beads or garnet sand from the abrasive barrel 75 through the connecting pipe 77. The extracted sandblasting abrasive will enter the sandblasting tube 8 through the telescopic pipe 84, and part of the sandblasting abrasive in the sandblasting tube 8 will be diverted to the bifurcated pipe 8. 2, and the nozzle 1 81 of the sandblasting tube 8 sprays the sandblasting abrasive at high speed onto the inner wall of the drainage pipe of the toilet blank 100, and the nozzle 2 83 of the bifurcated tube 82 sprays the sandblasting abrasive at high speed onto the inner wall of the flushing tank of the toilet blank 100, and then the electric push rod 2 85 is activated, and the electric push rod 2 85 drives the sandblasting tube 8 to rise and fall through the telescopic rod. At this time, the telescopic tube 84 between the material extraction pump 76 and the sandblasting tube 8 will be synchronously telescoped, so that the sandblasting tube 8 and the bifurcated tube 82 move in the drainage pipe and the flushing tank of the toilet blank 100 respectively, To ensure that the entire inner surface of the toilet blank 100 is fully polished, when the outer wall and the inner surface of the toilet blank 100 are polished, the cylinder 45 is used to control the support plate 44 to rotate and open, so that the sanding cloth 47 on the airbag 46 no longer contacts the toilet blank 100, and at the same time, the electric push rod 71 drives the entire mounting frame 72 to lift up and reset, so that the sandblasting tube 8 and the bifurcated tube 82 are respectively pulled out of the drainage pipe and the flushing trough of the toilet blank 100, and finally the polished toilet blank 100 can be manually transported and taken out from the placement table 3.

[0040] Embodiment 2: Based on embodiment 1, Fig.10 and Fig.11As shown, two sub-screen cylinders 141 are symmetrically installed on the bottom plate 2, and the sub-screen cylinder 141 is located below the placement table 3. Two discharge slots are provided on the raised table surface in the middle of the placement table 3. A feed pipe 142 is connected between the sub-screen cylinder 141 and the corresponding slots on the same side of the placement table 3. A discharge pipe 143 inclined downward is connected on the upper side wall of the sub-screen cylinder 141. A one-way valve 144 is provided on the discharge pipe 143. The one-way valve 144 is used to guide the sub-screen cylinder 141 to the discharge pipe 143 in one direction. A screen 145 is provided at the inlet of the sub-screen cylinder 141 inclined toward the discharge pipe 143. The screen 145 is used to screen the sandblasting abrasive and grinding dust entering the sub-screen cylinder 141. An air pump 146 is installed on the bottom plate 2, and the air inlet of the air pump 146 is connected through a suction pipe 147. The two sub-screen cylinders 141 are respectively connected to the bottom of the screen 145, and the vacuum pump 146 performs suction to the sub-screen cylinder 141 through the suction pipe 147. Since the one-way valve 144 on the discharge pipe 143 cannot be conducted to the sub-screen cylinder 141, a suction negative pressure is formed in the feed pipe 142 on the sub-screen cylinder 141. When sandblasting and polishing are performed, the sandblasting abrasive and polishing dust that fall from the drainage pipe of the toilet blank 100 onto the placement table 3 will be sucked into the feed pipe 142, and the sandblasting abrasive and polishing dust will be separated under the filtration of the screen 145. The sandblasting abrasive with larger particles is discharged from the discharge pipe 143 and recycled, while the polishing dust passes through the screen 145 into the suction pipe 147, and finally the polishing dust is sucked out by the vacuum pump 146 for subsequent environmental protection treatment.

[0041] like Fig.11 As shown, a dispersion rack 15 is rotatably installed inside the sub-screen cylinder 141. The dispersion rack 15 is a cylindrical frame and has a plurality of oscillating rollers circumferentially arranged thereon. The dispersion rack 15 is located between the outlet of the feed pipe 142 and the screen 145. The dispersion rack 15 is used to further disperse the sandblasting abrasive and grinding dust entering through the feed pipe 142. A second motor 151 is fixedly installed on the outer wall of the sub-screen cylinder 141. The output shaft of the second motor 151 is connected to the rotating shaft of the dispersion rack 15. The second motor 151 drives the dispersion rack 15 to rotate in the sub-screen cylinder 141, thereby accelerating the dispersion of the sandblasting abrasive and grinding dust falling into the sub-screen cylinder 141 and improving the separation efficiency of the screen 145 for the abrasive and grinding dust.

[0042] During the sandblasting and grinding process of the toilet blank 100 by the flush trough grinding mechanism 7, the blank dust generated by the grinding will be mixed with the sandblasting abrasive to form waste, and the waste will fall down from the drainage pipe of the toilet blank 100 to the placement table 3. By activating the vacuum pump 146, the vacuum pump 146 performs suction on the sub-screen cylinder 141 through the suction pipe 147, so that a suction negative pressure is generated in the sub-screen cylinder 141. At this time, since the one-way valve 144 on the discharge pipe 143 cannot be conducted to the sub-screen cylinder 141, the negative pressure in the sub-screen cylinder 141 will act on the feed pipe 142, and the feed pipe 142 can draw the waste on the placement table 3 into the sub-screen cylinder 141, and then through The second motor 151 drives the dispersion rack 15 to rotate on the sub-screen cylinder 141, thereby accelerating the dispersion of waste materials in the sub-screen cylinder 141, so that the sandblasting abrasive and dust can be evenly distributed in the sub-screen cylinder 141, and the waste materials falling into the sub-screen cylinder 141 will be filtered by the screen 145. The larger sandblasting abrasive cannot pass through the sieve holes of the screen 145, and is discharged from the discharge pipe 143 under the inclined guidance of the screen 145, so that the sandblasting abrasive can be recovered and processed later, while the fine grinding dust will pass through the sieve holes of the screen 145 into the suction pipe 147, and finally be discharged from the vacuum pump 146 and guided to a special treatment facility for environmental protection treatment, thereby reducing the impact on the environment.

[0044] S1, the push plate 124 of the multi-stage push rod 123 cooperates with the transmission roller 13 to accurately push the toilet blank 100 to the placement table 3, and the position is calibrated by the limit block 11 to prepare for grinding, and the first motor 6 is started to drive the outer wall grinding mechanism 4 to make circumferential movement along the sliding mouth between the placement table 3 and the tooth groove annular block 31. The airbag 46 adjusts the angle of the support plate 44 through the cylinder 45 under the control of the pressure sensor 52 and the built-in controller. The air pressure in the airbag 46 is kept constant to adapt to the irregular curved surface of the outer wall of the toilet blank 100, and the grinding cloth 47 is used to closely fit the outer wall of the toilet blank 100 for grinding;

[0045] S2, the electric push rod 1 71 drives the cover plate 74 to rise and fall. When the cover plate 74 seals the flushing groove of the toilet blank 100, the nozzle 1 81 of the sandblasting tube 8 and the nozzle 2 83 of the bifurcated tube 82 are respectively extended into the drainage pipe and the flushing groove of the toilet blank 100, and the electric push rod 2 85 is cooperated to control the lifting of the sandblasting tube 8, and the sandblasting abrasive in the abrasive barrel 75 is extracted by the material extraction pump 76, and the drainage pipe and the inner wall of the flushing groove are sandblasted and polished by the nozzle 1 81 and the nozzle 2 83 respectively;

[0046] S3. The waste generated by grinding falls onto the placement table 3, enters the sub-screen cylinder 141 through the feed pipe 142, accelerates the dispersion of the material through the dispersion rack 15, and cooperates with the screen 145 to separate the large particles of sandblasting abrasive and fine dust, so that the sandblasting abrasive can be recycled and reused, and the dust is sucked away by the vacuum pump 146.
