When the device is used, the sealing cover 6 is opened, paint is poured into the box body 1 from the feeding hole, at the moment, the floating disc 8 moves upwards under the action of buoyancy, after the paint is added, the sealing cover 6 is covered, then, the air pump 4 is started to convey air into the box body 1 from the air pipe 5, the air pressure in the box body 1 is increased, the rated pressure of the first pressure release valve 9 of the air pressure value is increased, the paint is conveyed to the nozzle 3 from the fixed pipe 2 under the action of the air pressure and is sprayed out from the nozzle 3 towards the direction of the fixed pipe 2 away from the air pipe 5, paint spraying is realized, the floating disc 8 is lowered along with the reduction of the paint in the box body 1, when the floating disc 8 is attached to the fixed ring 7, the air pressure in the box body 1 is increased again, when the air pressure is higher than the rated pressure of the pressure release valve 9, the paint is discharged from the air release hole, the situation that the air is sprayed out from the nozzle 3, here, the push plate 12 drives the guide rod 16 to move downwards under the action of the air flow through the downward flow of the air in the air pipe 5, and the spring 17 is compressed, the downward movement of the push plate 12 drives the locking rod 11 to move towards the direction away from the fixed pipe 2 through the connecting rod 13 and insert into the locking hole, so that the function of locking the sealing cover 6 can be realized, the sealing cover 6 is prevented from being loosened with the box body 1 under the action of air pressure, so that the paint cannot be pressed into the fixed pipe 2 after the air is discharged from the charging hole, after the air pump 4 stops operating, the push plate 12 is reset under the elastic action of the spring 17 and abuts against the limiting block 14, the reset of the push plate 12 drives the locking rod 11 to reset through the connecting rod 13, so that the sealing cover 6 is unlocked, the sealing cover 6 can be normally opened, and the floating disc 8 moves downwards along with the reduction of the paint in the box body 1 during the painting period, namely, the ball screw bearing 22 can be driven to move downwards on the screw rod 21, because the ball screw bearing 22 converts the rotary motion into the linear motion, or converts the linear motion into the bearing of the rotary motion, thereby the screw rod 21 can drive the rotating shaft 20 to rotate under the supporting action of the first bearing 19, the rotating shaft 20 rotates to drive the stirring rod 18 to synchronously rotate, the function of stirring paint can be realized through the rotation of the stirring rod 18, the sedimentation of components such as curing agent in the paint is prevented, meanwhile, the air in the air pipe 5 is conveyed into the rotating pipe 23 and then conveyed into the auxiliary pipe 27 from the connecting pipe 25, and conveyed into the box body 1 from the bottom end of the auxiliary pipe 27, the fan blades 28 are rotated by using the flow of the air in the rotating pipe 23 as the driving force, thereby the connecting shaft 30 can rotate under the supporting action of the second bearing 29, the rotation of the connecting shaft 30 drives the rotating pipe 23 to rotate, the rotation of the rotating pipe 23 drives the auxiliary pipe 27 to rotate through the connecting pipe 25, because the distance between the axis of the auxiliary pipe 27 and the axis of the fixed pipe 2 is greater than the radius of the floating disc 8, and the sum of the distance between the axis of the auxiliary pipe 27 and the axis of the air pipe 5 and the distance between the axis of the air pipe 5 and the axis of the fixed pipe 2 is greater than the diameter of the floating disc 8, the air discharged from the auxiliary pipe 27 can be intermittently applied to the top of the floating disc 8, when the air is applied to the top of the floating disc 8, the floating disc 8 can be moved downwards again under the action of the air flow, and when the air discharged from the auxiliary pipe 27 can not be directly applied to the floating disc 8, the floating disc 8 is moved upwards to the horizontal plane of the paint under the action of the floating disc 8, and the intermittent reciprocating lifting of the floating disc 8 can be realized while the floating disc 8 descends, that is to ensure that the stirring rod 18 intermittently rotates reversely in, the function of stirring paint in different directions is realized, and the paint stirring effect is improved.
Compared with the prior art, this a paint spraying apparatus for boats and ships preparation can prevent through complementary unit that 3 blowout air of nozzle from and lead to the lacquer painting fold to appear, the jet-propelled effect has been improved, compare with current complementary unit, this complementary unit can also realize pinning the function of sealed lid 6, the practicality is stronger, moreover, the function of stirring paint has still been realized through rabbling mechanism, compare with current rabbling mechanism, intermittent type nature reverse rotation when this rabbling mechanism can realize stirring rod 18 pivoted, the stirring degree of consistency is higher.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
