Referring to fig. 1, more specifically, the upper end of the spraying box 1 is provided with a cover 11 with a mounting opening, a partition plate 12 is arranged inside the spraying box 1, the workbench 2 is arranged above the partition plate 12, the spraying box 1 is fixedly provided with a driving motor 21 below the partition plate 12, and an output shaft of the driving motor 21 penetrates through the partition plate 12 to be fixedly connected with the workbench 2, and is used for driving the workbench 2 to horizontally rotate in the spraying box 1.
Referring to fig. 1, the wind source mechanism 4 includes a rod that can be inserted into the perforated ceramic 5 and an electric push rod 41 for driving the rod to be inserted into the perforated ceramic 5. In this embodiment, the supporting rod is a first electric linear guide 42, and the first electric linear guide 42 is disposed on the cover 11 and extends into the porous ceramic 5 through the cover 11. An air nozzle 43 for blowing air is arranged on the sliding seat of the first electric linear guide rail 42, an air pipe 44 is connected to the air nozzle 43, and the air pipe 44 is connected with an air pump 45. The side of the tuyere 43 facing the painting mechanism 3 is provided with several air blowing openings 431 for blowing air. The end part of the first electric linear guide rail 42 extending into the porous ceramic 5 is provided with water absorption cloth 46, and the water absorption cloth 46 is used for absorbing redundant glaze water in the porous ceramic 5. The first electric linear guide rail 42 is further provided with a cover 47 for covering the opening of the perforated ceramic 5, and the cover 47 can block the opening of the perforated ceramic 5 from being communicated with the outside air, so that a relative closed space is formed in the perforated ceramic 5, and the airflow flowing effect of the holes of the perforated ceramic 5 is enhanced.
Referring to fig. 1, the spraying mechanism 3 includes a second electric linear guide 31 disposed on one side in the spraying box 1, a spraying seat 32 is disposed on a sliding seat of the second electric linear guide 31, the spraying seat 32 is connected with a delivery pipe 34, a plurality of spray heads 33 for spraying glazing are disposed on the spraying seat 32, and the spraying is communicated with the delivery pipe 34 through the spraying seat 32. The driving motor 21, the air pump 45, the first electric linear guide rail 42, the second electric linear guide rail 31 and a feeding valve (not shown in the figure) on the conveying pipe 34 of the invention are all electrically connected with the existing numerical control machine and controlled by the numerical control machine.
Referring to fig. 1, when the present invention works, the porous ceramic 5 is fixedly placed on the upper end surface of the worktable 2, and a person skilled in the art can refer to the prior art, and add a suitable fixing mechanism (not shown in the figure) on the worktable 2, and for better fixing the porous ceramic 5, the specific scheme of the fixing mechanism is not described herein again. Subsequently, under the control of the numerical control machine, the driving motor 21 drives the workbench 2 to rotate, and the second electric linear guide rail 31 drives the nozzle 33 to move up and down, so that the outer surface of the perforated ceramic 5 is subjected to comprehensive and fine spraying and glazing operation.
Referring to fig. 1, the other parts of the outer surface of the porous ceramic 5 are sprayed with glaze in the same manner as the conventional spraying glaze, and the key point of the present invention is the spraying operation of the holes on the porous ceramic 5. When the second electric linear guide rail 31 controls the spraying base 32 to spray the holes of the perforated ceramics 5, the air nozzle 43 is driven by the first electric linear guide rail 42 to move to the position corresponding to the holes of the perforated ceramics 5, and under the action of the air pump 45, the air nozzle 43 blows air to the holes of the perforated ceramics 5, and the blown air force is slightly smaller than the spraying pressure of the glaze water sprayed by the spray head 33 on the spraying base 32. Therefore, when the glaze water passes through the holes in the spraying hole part, the glaze water meets wind force blown out by the wind nozzle 43, air turbulence is formed at the holes, the time that the glaze water passes through the holes is slowed down, and meanwhile, the glaze water can be coated on the inner side walls of the holes through the air turbulence, so that the problem of glazing coating on the inner side walls of the holes is solved. The method of the embodiment is suitable for most of the porous ceramics 5 with moderate or large pore diameter.
Example two
Referring to fig. 2, the structure of the present embodiment is substantially the same as that of the embodiment, and is not described herein, but the difference between them is: be equipped with an tuyere 43 that is used for induced drafting on first electronic linear guide 42's the slide, tuyere 43 is equipped with a plurality of inlet scoop 432 that are used for induced drafting dorsad or towards spraying mechanism 3 one side, and when wind-force was enough, the inlet scoop 432 that set up dorsad can effectually prevent in glaze water suction inlet scoop 432, when wind-force was not enough, then adopted towards spraying mechanism 3. When the spraying mechanism 3 is used for spraying holes on the perforated ceramics 5, the air nozzle 43 is driven by the first electric linear guide rail 42 to move to the corresponding position of the holes on the perforated ceramics 5, and air is pumped by the air pump 45, so that negative pressure is formed inside the perforated ceramics 5, and glaze water is conveniently sprayed into the holes. This implementation is applicable to the foraminiferous pottery 5 that the aperture is less or hole opening direction is upwards or the downward sloping, at the foraminiferous pottery 5 that the coating aperture is less, when the spraying glazing, because under the tension effect of water, glaze water forms the water curtain easily on the hole surface for glaze water is difficult to spout in the hole. The air suction nozzle 43 of the invention sucks air, so that the water curtain can be damaged, glaze water can be better sucked into the hole, and the inner side wall of the hole is coated; when the porous ceramic 5 with the upward or downward inclination of the opening direction of the hole is coated, the hole is in an inclined state, so that glaze water which is horizontally sprayed and glazed has a certain included angle with the hole, and can only be sprayed to the local side wall of the hole but can not be completely sprayed into the hole.
EXAMPLE III
Referring to fig. 3, the structure of the present embodiment is substantially the same as that of the embodiment, and is not described herein again, but the difference between them is: the air source mechanism 4 comprises a supporting rod which can extend into the porous ceramic 5, the supporting rod is provided with two rotating fan blades 48 which are used for disturbing air in the porous ceramic 5 to form turbulent flow, the two rotating fan blades 48 are made of flexible materials and are respectively distributed above and below the porous ceramic 5 to respectively fan downwards and upwards, namely the two rotating fan blades 48 fan in opposite directions to form air turbulent flow. The supporting rod is a rotating shaft 481 of a rotating motor 480, and the rotating fan blade 48 is fixed on the rotating shaft 481. The end of the rotating shaft 481 is connected to the water absorption cloth 46 through a bearing cover 482. This implement rotatory fan blade 48 forms the air turbulence in foraminiferous ceramic 5 in the coating of pore wall and act on, except that the interference glaze water that can play flows through the hole, the effect of coating the pore wall is outside, glaze water spouts into the hole after, under the effect of air turbulence, can irregularly coat on foraminiferous ceramic 5 inside walls, form various shapes, the glaze spot that the distribution position is all different, make the glaze spot diverse of each foraminiferous ceramic 5 inside walls, through the glaze spot distribution diagram of scanning and this foraminiferous ceramic 5 inside walls of record, can play the record, mark and guard against falsification etc. effect.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
