[0019] In summary, the present invention mainly has the following beneficial effects: 1. The present invention uses an auxiliary component, a driving component, a dust cleaning and drying integrated component and a spraying component. First, the auxiliary component is used to realize the clamping and limiting of the shell and the switching of the cleaning and spraying processes. Specifically, the first electric slide rail is started, and the clamping plate will move at this time, thereby realizing the clamping and limiting of the shell. Further, the cylinder is started, and the cylinder will drive the top plate to move upward, that is, drive the entire spraying device to move upward, and then the driving motor will drive the cylinder to rotate one hundred and eighty degrees until the first nozzle is above the shell. Then the hot air blower is started, and the hot air blower will inhale air from the outside and filter the dust, and then output it to the air box through the telescopic air supply pipe, and the gas in the air box will be sprayed through the first nozzle, thereby realizing the dust cleaning effect on the shell. At the same time, the second electric slide rail is started, and the second electric slide rail will drive the air box to reciprocate through the slider, thereby realizing the reciprocating movement of the first nozzle, and starting the turntable clamping the shell, so that The shell body achieves a full range of dust cleaning effects under the dual effects of the rotating disk and the lateral driving of the slider, which significantly improves the quality of its spray coating. After completing the dust cleaning operation on the shell body, the second nozzle is moved to the top of the shell body for spraying operation through the cooperation of the cylinder and the driving motor. Specifically, the paint in the liquid storage tank will enter the liquid supply tank through the telescopic liquid supply pipe, so that the second nozzle can draw paint from the liquid supply tank and spray it onto the outer wall of the shell body to achieve the spraying operation on the shell body. During the spraying process, the second electric slide rail will also drive the second nozzle to reciprocate through the slider, and the turntable will also drive the shell body to rotate, thereby achieving a full range of automated spraying effects on the shell body. After the spraying is completed, the above steps are repeated, so that the first nozzle is moved to the top of the shell body again, and then the hot air output by the hot air blower is used to achieve the drying effect of the shell body, which accelerates the solidification of the coating and significantly improves the production efficiency. 2. The present invention uses a transmission component, a cleaning component and a stirring component. When the turntable is running, the driving rack on the inner end face of the turntable drives the gear shaft to rotate. After the gear shaft rotates, it drives the driving gear to rotate. When the dust cleaning or drying operation of the shell is performed, the first driven gear is meshed with the driving gear. Therefore, under the action of the driving gear, the first driven gear rotates and drives the extrusion wheel to rotate through the synchronous shaft. After the extrusion wheel rotates, it will contact the convex block on the end face of the driven plate, thereby realizing the extrusion of the convex block, that is, realizing the extrusion of the driven plate. After the driven plate is squeezed, it will drive the filter to move downward and compress the reset spring. When the extrusion wheel rotates until no extrusion force is applied to the convex block, the filter will be quickly reset under the action of the reset spring. At this time, the filter will jump horizontally repeatedly, thereby utilizing vibration to achieve the dust removal effect on the filter. Further, when the air box moves back and forth, it will drive the cleaning brush to move synchronously through the synchronous rod, thereby utilizing the cleaning brush to clean the filter, further improving the cleaning effect of the filter. The cleaning effect of the filter screen is achieved, thereby ensuring the air intake of the hot air blower, that is, ensuring the quality of the shell spraying operation. In addition, when the shell is sprayed, the second driven gear is meshed with the driving gear. Therefore, under the action of the driving gear, the second driven gear will rotate, and the rotation of a group of second driven gears will drive the reciprocating screw to rotate. The rotation of the reciprocating screw will drive the moving block on its outer wall to reciprocate under the action of the limit rod, and the movement of the moving block will synchronously drive the first impeller and the second impeller to move. At the same time, the second group of second driven gears will drive the first impeller to rotate through the telescopic rod, thereby achieving the stirring and mixing effect of the paint in the liquid storage tank and improving the spraying quality. Furthermore, after the first impeller rotates, the first bevel gear on the inner side of the first impeller will rotate, and after the first bevel gear rotates, it will drive the second bevel gear to rotate in the opposite direction through the third bevel gear. Therefore, the second impeller will rotate in the opposite direction to the first impeller, thereby realizing positive and negative bidirectional stirring of the paint, further improving the stirring effect.

[0031] The working principle of the present invention is as follows: first, the auxiliary component 2 is used to realize the clamping and limiting of the housing 1 and the switching of the cleaning and spraying processes. Specifically, the first electric slide rail 202 is started, and the clamping plate 203 moves at this time, thereby realizing the clamping and limiting of the housing 1; Further, the cylinder 206 is started, and the cylinder 206 drives the top plate 205 to move upward, that is, drives the entire spraying device to move upward, and then the driving motor 207 drives the cylinder 206 to rotate 180 degrees until the first spray head 402 is above the housing 1; Start the hot air blower 404, which will inhale air from the outside, filter the dust, and then output it to the air box 401 through the telescopic air supply pipe 403. The gas in the air box 401 will be ejected through the first nozzle 402, thereby achieving a dust removal effect on the shell 1. At the same time, start the second electric slide rail 302, which will drive the air box 401 to reciprocate through the slider 303, thereby achieving the reciprocating movement of the first nozzle 402. In addition, start the turntable 204 that clamps the shell 1, so that the shell 1 can achieve an all-round dust removal effect on the shell 1 under the dual effects of the rotation of the turntable 204 and the lateral driving of the slider 303, thereby significantly improving the quality of its spray coating; After the dust cleaning operation on the shell 1 is completed, the second nozzle 502 is moved to the top of the shell 1 for spraying operation through the cooperation of the cylinder 206 and the drive motor 207. Specifically, the paint in the liquid storage tank 504 will enter the liquid supply tank 501 through the telescopic liquid supply pipe 503, so that the second nozzle 502 can draw paint from the liquid supply tank 501 and spray it onto the outer wall of the shell 1 to achieve the spraying operation on the shell 1. During the spraying process, the second electric slide rail 302 will also drive the second nozzle 502 to reciprocate through the slider 303, and the turntable 204 will also drive the shell 1 to rotate, thereby achieving an all-round automatic spraying effect on the shell 1; After spraying is completed, the above steps are repeated so that the first nozzle 402 is moved again to the top of the shell 1, and then the hot air output by the hot air blower 404 is used to dry the shell 1, thereby accelerating the solidification of the coating and significantly improving the production efficiency; It is worth noting that while the turntable 204 is running, the driving rack 603 on the inner end surface of the turntable 204 will drive the gear shaft 602 to rotate, and the gear shaft 602 will drive the driving gear 601 to rotate. When the dust cleaning or drying operation of the shell 1 is performed, the first driven gear 604 is meshed with the driving gear 601. Therefore, under the action of the driving gear 601, the first driven gear 604 will rotate and drive the extrusion wheel 705 to rotate through the synchronous shaft 704, and the extrusion wheel 70 After the extrusion wheel 705 rotates, it will contact the protrusion 707 on the end surface of the driven plate 706, thereby squeezing the protrusion 707, that is, squeezing the driven plate 706. After the driven plate 706 is squeezed, it will drive the filter 702 to move downward and compress the reset spring 703. When the squeezing wheel 705 rotates until there is no squeezing force on the protrusion 707, the filter 702 will quickly reset under the action of the reset spring 703. At this time, the filter 702 will jump horizontally repeatedly, so as to achieve the dust removal effect of the filter 702 by vibration. Furthermore, when the air box 401 moves back and forth, it will drive the cleaning brush 708 to move synchronously through the synchronization rod 709, so that the cleaning brush 408 can be used to clean the filter 702, further improving the cleaning effect of the filter 702, thereby ensuring the air intake of the hot air blower 404, that is, ensuring the quality of the spraying operation of the shell 1; In addition, when the shell 1 is being sprayed, the second driven gear 605 is meshed with the driving gear 601. Therefore, under the action of the driving gear 601, the second driven gear 605 will rotate, and the rotation of a group of second driven gears 605 will drive the reciprocating screw 801 to rotate. The rotation of the reciprocating screw 801 will drive the moving block 802 on its outer wall to reciprocate under the action of the limit rod 803, and the movement of the moving block 802 will synchronously drive the first impeller 804 and the second impeller 805 to move. At the same time, the second group of second driven gears 605 will drive the first impeller 804 to rotate through the telescopic rod 806, thereby achieving a stirring and mixing effect on the paint in the liquid storage tank 504 and improving the spraying quality. Furthermore, after the first impeller 804 rotates, the first bevel gear 807 inside the first impeller 804 will rotate. After the first bevel gear 807 rotates, it will drive the second bevel gear 808 to rotate in the opposite direction through the third bevel gear 809. Therefore, the second impeller 805 will rotate in the opposite direction to the first impeller 804, thereby realizing forward and reverse bidirectional stirring of the paint, further improving the stirring effect.
