But the rotating direction of the deflector rod 30 in the finish paint cavity 13 is opposite to that of the deflector rod 30 in the primer paint cavity 12; at this time, the driving lever 30 in the primer chamber 12 can push the first spring 29 to move, the first spring 29 can push the piston rod 27 to push the honeycomb piston valve 26 to move, so that the liquid replenishing port 28 is no longer blocked along with the movement of the honeycomb piston valve 26, and therefore the raw material in the feeding pipe 03 can flow into the primer chamber 12 through the honeycomb piston valve 26 and the liquid replenishing port 28, and the process of replenishing the raw material in the primer chamber 12 is achieved.
When the paint spraying barrel 06 moves to the tail end of the guide rail groove 09 to complete the process of one-time paint spraying, the finish paint raw material in the finish paint cavity 13 is used up, the primer paint cavity 12 can be filled with the primer paint raw material in the process of continuous feeding of the feeding pipe 03 to the primer paint cavity 12, so that the hollow floating ring 21 can float upwards under the action of buoyancy, the hollow floating ring 21 can push the sliding rod 23 to ascend, the sliding rod 23 can pull the pull rod 33 to ascend, the pull rod 33 can pull the mounting block 35 to pull the upper air blocking pipe 34 to ascend, the upper air blocking pipe 34 can pull the lower air blocking pipe 37 to ascend through the support rod 36, the upper air blocking pipe 34 can not block the position where the stirring blade 14 and the rotating pipe 42 are communicated in the primer paint cavity 12, and the lower air blocking pipe 37 can block the position where the stirring blade 14 and the rotating pipe 42 are communicated in the finish paint cavity 13. In the ascending process of the upper air blocking pipe 34 and the lower air blocking pipe 37, the rotating pipe 42 is continuously limited by the second limiting sheet 43, so that only when the priming paint in the priming paint cavity 12 is full of the priming paint, the buoyancy of the priming paint can be greater than the stiffness coefficient of the third spring 45, the second limiting sheet 43 can push the chuck 44 to slide into the installation cylinder 46, the third spring 45 is compressed, the hollow floating ring 21 can be ensured to rise along with the liquid level in the priming paint cavity 12, the lower air blocking pipe 37 can not directly block the position where the stirring blade 14 in the priming paint cavity 13 is communicated with the rotating pipe 42, the finish paint in the priming paint cavity 13 can not be sprayed, meanwhile, the upper air blocking pipe 34 can not block the position where the stirring blade 14 in the priming paint cavity 12 is communicated with the rotating pipe 42, and the priming paint spraying in the priming paint cavity 12 can be started. So as to ensure that the process of replenishing the raw material in the primer cavity 12 is continuously carried out, and simultaneously, the finish paint in the finish paint cavity 13 can be continuously sprayed out until the primer cavity 12 is filled with the raw material.
When the paint spraying barrel 06 moves to the tail end of the guide rail groove 09 to complete the process of primary paint spraying, firstly, the conveyor belt 02 can drive the unmanned aerial vehicle shell which is finished with paint spraying to move out of the case 01, the case 01 feeds a new batch of unmanned aerial vehicle shells into the case 01, at the moment, the cylinder starts to drive the paint spraying barrel 06 to start to reset, at the moment, because the bottom paint raw material and the filling material are filled in the primer cavity 12, the hollow floating ring 21 can move according to the process, the upper wind blocking pipe 34 is made to move to the position above the communicated position of the stirring blades 14 and the rotating pipe 42 in the primer cavity 12, and the lower wind blocking pipe 37 is made to move to the position where the stirring blades 14 and the rotating pipe 42 are communicated in the finish paint cavity 13, so that the rotating pipe 42 cannot continuously blow gas to the stirring blades 14 in the finish paint cavity 13, and at the moment, the rotating pipe 42 can blow gas to the stirring blades 14 in the primer cavity 12. Because the rotating pipe 42 can be rotated in the opposite directions by the stirring blades 14 in the primer cavity 12 and the stirring blades 14 in the finish paint cavity 13, the hot air blown into the rotating pipe 42 by the blowing pipe 05 flows into the stirring blades 14 in the primer cavity 12, so that the rotating pipe 42 is driven by the stirring blades 14 in the primer cavity 12 to rotate in the opposite rotating direction to the rotating direction in which the rotating pipe 42 is driven by the stirring blades 14 in the finish paint cavity 13. So that the finish paint cavity 13 starts to replenish the finish paint raw material in the same process as the above-mentioned primer paint cavity 12 replenishes the primer paint raw material. Meanwhile, as in the process of spraying the finish paint in the finish paint chamber 13, the primer paint chamber 12 starts to spray the primer paint downwards through the communicating pipe 19.
At this moment, because stirring leaf 14 in priming paint chamber 12 begins to drive the commentaries on classics pipe 42 and rotates, thereby the rotation of commentaries on classics pipe 42 can drive the rotation of rotary drum 24 through the transmission of a circular section of thick bamboo 40, thereby rotary drum 24 can drive auger 38 and rotate, thereby in feeding into last feed cylinder 39 with the sandblast raw materials in the sandblast chamber 11, again through last feed cylinder 39 feed into in blowing pipe 05, when rethread blowing pipe 05 flowed into commentaries on classics pipe 42, blow by blowing in the blowing pipe 05 that hot-blast quick blow send to newly feed into on a batch unmanned aerial vehicle's the shell, thereby the realization carries out sand blasting to the unmanned aerial vehicle shell. When the stirring blade 14 in the finish paint cavity 13 drives the rotating pipe 42 to rotate, the rotating pipe 24 is also driven to rotate, but due to the structural characteristic of the auger 38, only unidirectional feeding is realized, so that the sand in the sand blasting cavity 11 cannot be blasted out during drying.
After the priming paint raw material in the priming paint cavity 12 is sprayed, along with the descending of the priming paint raw material liquid level in the priming paint cavity 12, the buoyancy effect on the hollow floating ring 21 gradually descends, but the buoyancy supporting effect on the hollow floating ring 21 can also be achieved, so that the chuck 44 can be supported by the second limiting sheet 43 and cannot overcome the elastic force of the third spring 45, only when the priming paint raw material in the priming paint cavity 12 is used up, the gravity of the hollow floating ring 21 is greater than the elastic force of the third spring 45, so that the chuck 44 can be pushed into the mounting cylinder 46 by the second limiting sheet 43 again, and therefore, the upper wind blocking pipe 34 can shield the position where the stirring blade 14 in the priming paint cavity 12 is communicated with the rotating pipe 42 again, at the moment, the air cylinder 07 drives the paint spraying barrel 06 to move to the initial position of the guide rail groove 09, and the paint spraying and drying functions can be achieved by pushing the paint spraying barrel 06 again.
Thereby realize constantly carrying out the spraying stoving to unmanned aerial vehicle to and the sand blasting before carrying out the spraying, and the priming paint spraying after the sand blasting. The primer is sprayed, so that the adhesive force of the finish paint can be improved, the fullness of the finish paint is increased, the alkali resistance is provided, the anticorrosion function is provided, and the like, and meanwhile, the uniform absorption of the finish paint can be ensured, so that the paint system can exert the optimal effect. Because the functions of the finish paint and the primer paint are different, the finish paint is more focused on the final decoration and appearance effects, and the primer paint is focused on improving the adhesive force, the anticorrosion function, the alkali resistance and the like. When the sand blasting process is carried out, the surface of the workpiece obtains certain cleanliness and different roughness due to the impact and cutting action of the sprayed abrasive on the surface of the workpiece, so that the mechanical property of the surface of the workpiece is improved, the fatigue resistance of the workpiece is improved, the adhesive force between the workpiece and a coating is increased, the durability of a coating is prolonged, and the leveling and decoration of the coating are facilitated.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
