When crimping 31 accumulates certain silver paste, feed back pipe 33 is evacuated by air exhauster, so by the silver paste at crimping 31 from
Feedback outlet 32 carries out suction recycling, and silver paste after the recovery is imported in silver paste pond again and recycled, and is further ensured that monolithic is made pottery
Porcelain surface coating quality, save material cost.
In use, the pin of layered ceramic is fixed on pedestal 21, idler wheel 11 is driven to rotate by decelerating motor area, into
And annulus 2 is driven to rotate, while the silver paste of high pressure is sprayed from nozzle 3, carries out whitewashing processing to layered ceramic surface；Constantly turn
Dynamic annulus 2 can make layered ceramic surface silver paste spray it is more uniform, while prevent the silver paste on layered ceramic surface because
Gravity and flow, and then layered ceramic surface formed flow cracks, influence layered ceramic surface silver paste coating quality；By flat
Flat-shaped bell-shaped nozzle 3, can control silver paste emission direction, so that silver paste is in band-like ejection by spraying, reduce the loss of silver paste
To save silver paste cost；It controls driving motor 25 by controller to rotate, driving motor 25 is rotated with moving gear 26, passes through tooth
Wheel 26 slides in sliding slot 23 with the drive nozzle 3 that engages of rack gear 24, since sliding slot 23 is in U-shape structure, so that nozzle 3 is sliding
The exterior contour of motion profile fitting layered ceramic in the process, further such that the silver paste spraying on layered ceramic surface is more equal
It is even, it prevents local silver paste coating thickness from increasing, wastes silver paste raw material, reduce layered ceramic surface coating quality；When nozzle 3 slides
When to the U-shaped corner of sliding slot 23, tooth engagement on gear 26 and 42 surface of conveyer belt, simultaneously because conveyer belt 42 is close to sliding slot
The direction of motion of 23 sides is consistent with 3 direction of motion of nozzle, and conveyer belt 42, which is rotatably assorted when gear 26 rotates, accelerates nozzle 3 in cunning
The sliding speed of the U-shaped corner of slot 23, and then reduction layered ceramic edges and corners silver paste coating thickness is blocked up, saves silver paste, into
And the cost that saves material；The silver paste sprayed at nozzle 3 can be reduced by the crimping 31 of arc to converge at 3 outer rim of nozzle,
And then it is sprayed onto layered ceramic surface after being gathered into silver paste drop, layered ceramic superficial punctate protrusion is caused, layered ceramic surface is reduced
The surface smoothness of silver slurry layer influences outer tube quality pass rate；When crimping 31 accumulates certain silver paste, by air exhauster to return
Expects pipe 33 is evacuated, and then the silver paste at crimping 31 is carried out suction recycling from feedback outlet 32, and silver paste after the recovery is converged again
Enter and recycled in silver paste pond, be further ensured that layered ceramic surface coating quality, save material cost
