The invention also discloses a spraying method for ceramic processing, and the spraying device for ceramic processing comprises the following steps:

s1, when a workpiece needs to be sprayed, the workpiece is placed at the top end of the rotating seat, then the hydraulic cylinder is started, the output end of the hydraulic cylinder drives the first rack to reset, when a latch on the outer wall of the other side of the first rack is in contact with the third small straight gear, the third small straight gear is driven to drive the first large synchronizing wheel to rotate through the rotating rod, the first synchronizing belt is driven to drive the first one-way lead screw to rotate quickly through the second small synchronizing wheel, and the first one-way lead screw drives the threaded sleeve to drive the limiting disc to move downwards through the connecting disc;

s2, when the connecting disc moves downwards, the telescopic sleeve rod is driven to move downwards, the telescopic sleeve rod moves downwards and drives the arc-shaped pressing block to move downwards, the circular plate is pushed to extrude the sixth spring to drive the third rack to move downwards, the fourth small straight gear is driven to drive the first bevel gear to rotate through the third one-way lead screw, the second bevel gear is driven to rotate, the other two first bevel gears are driven to rotate through the second one-way lead screw, the three third one-way lead screws rotate simultaneously, the rectangular sliding block is driven to drive the idler wheel to approach a workpiece through one rectangular plate, the fifth small straight gear is driven to rotate through the fourth rack when the rectangular sliding block drives the rectangular plate to approach the workpiece, the idler wheel is driven to rotate through the rectangular plate, the workpiece position at the top end of the rotating seat is corrected through the three rectangular plates, the workpiece is driven to move close to the central position of the rotating seat, when the three rectangular plates are in contact with the outer wall of the rotating plate, the idler wheel continues to rotate through the seventh spring when the three rectangular plates are in contact with the workpiece;

s3, when the circular plate moves downwards to the maximum position and the telescopic sleeve rod continues to move downwards, the eighth spring is extruded to enable the telescopic sleeve rod to contract, when the hydraulic cylinder is in contact with the top end of a workpiece and the connecting disc continues to move downwards, the limiting disc abuts against the top end of the workpiece, so that the fourth sealing piston block extrudes the fifth spring to slide relative to the third sealing sleeve, gas in the third sealing sleeve is pushed into the fourth sealing sleeve through the gas guide pipe, the third sealing piston block is pushed to extrude the fourth spring to drive the telescopic sleeve rod to move towards the direction away from the fourth sealing sleeve through the fourth guide rod, the arc-shaped pressing block is moved away from the top end of the circular plate, and therefore the sixth spring is not pushed to reset by the circular plate under the external force any more, and the rectangular plate is reset;

s4, when the limiting disc abuts against the top end of a workpiece, the threaded sleeve continuously drives the connecting disc to move downwards, so that the first sealing piston block extrudes the first spring to move relative to the second sealing sleeve, air in the second sealing sleeve is pushed into the first sealing sleeve through the telescopic hose, the air continuously enters the first sealing sleeve, the second sealing piston block is pushed to extrude the second spring to drive the second guide rod to move downwards, the second rack is further driven to move downwards, the second rack moves downwards to drive the second small straight gear to drive the worm to rotate, the worm wheel is further driven to drive the second one-way screw rod to rotate, the connecting shell is further driven to drive the arc-shaped seat to move downwards through the rectangular block and the supporting rod, the spray head is further driven to move downwards, and after the threaded sleeve moves to a designated position, the sliding position of the first sealing piston block relative to the inside of the second sealing sleeve is different according to the height of the workpiece, so that the adjusted spray head is different in position, and the spray head can be automatically adjusted to the height of the workpiece;

s5, work as first rack opposite side outer wall latch with the little straight-teeth gear separation of third back, the output of pneumatic cylinder continues to drive first rack resets, makes first rack one side outer wall latch with the contact of first big straight-teeth gear, drive first big straight-teeth gear rotates, thereby the drive first little straight-teeth gear passes through it drives the work piece and carries out the rotation to rotate the seat, first pivot drives when rotating the big synchronizing wheel of second rotates, drives the second synchronizing belt drives through first little synchronizing wheel reciprocal lead screw rotates, and then the drive the sliding seat drives the connection shell carries out reciprocating motion from top to bottom, works as the connection shell moves down through the rectangle piece with the bracing piece drives when the arc seat moves down, drives a plurality ofly the shower nozzle moves down, works as the bottom of shower nozzle with during the contact of T shape pole, it is tensile when continuing to move down to connect the shell the third spring, and then makes the shower nozzle all the time with the work piece parallel and level.

Compared with the prior art, the invention has the beneficial effects that:

1. by arranging the self-adaptive adjusting mechanism and the automatic calibrating mechanism, the height of the spray head is adjusted to be parallel to the height of the workpiece by the self-adaptive adjusting mechanism, and meanwhile, the position of the workpiece at the top end of the rotating seat is corrected by the automatic calibrating mechanism, so that the workpiece is positioned on the inner side of the arc-shaped seat, a plurality of spray heads after the position is adjusted can accurately spray coating to the outer wall of the workpiece, and the height of the spray head can be self-adapted along with the height of the workpiece by the matching of the parts, so that the practicability of the device is improved, and further, the workpiece can be sprayed by equipment;

2. through setting up self-adaptation adjustment mechanism, rotate certain number of turns through the one-way lead screw of height drive second of automatic regulating assembly according to the work piece, and then the drive connection shell passes through the rectangular block and drives the arc seat downstream with the bracing piece to drive the shower nozzle downstream and to the height of aliging with the work piece, realized with this that the height of shower nozzle can be along with the function that highly carries out the self-adaptation of work piece, so that improved the practicality of device.

3. Through setting up automatic calibration mechanism, drive the rectangular plate and rotate through fourth rack drive fifth little straight-teeth gear when being close to the work piece when the rectangle slider, and then drive the gyro wheel through the rectangular plate through the second pivot and rotate, correct the work piece position on roating seat top through three rectangular plate, make the work piece be close to the central point that roating seat and put and remove, realize carrying out the function of correcting to the work piece position with this, so that the work piece aligns with the shower nozzle after adjusting, and then be convenient for carry out the spraying to the work piece.
