A lead screw 26 passing through the upper ring 25 and driven by a motor I 27 is provided on the support portion 23. An air storage cavity 28 is provided in the side wall of the convex seat 22. A receiving groove 210 is further provided at the bottom of the convex seat 22. A spraying assembly 29 is provided in the receiving groove 210.

[0025] The spraying assembly 29 is connected to a push plate 212 in the air storage cavity 28 through a vertical pipe 211. An air inlet 213 is provided at the top end of the side wall of the vertical pipe 211. A heating pipe 214 is provided at the bottom of the push plate 212. A screw 215 passing through the push plate 212 and driven by a motor II 216 is provided in the air storage cavity 28.

[0026] The spraying assembly 29 includes an annular seat 291. A drying channel 292, a spraying channel 293 and an air extraction channel 294 are arranged around in the side wall of the annular seat 291. The spraying channel 293 is located between the drying channel 292 and the air extraction channel 294. The air extraction channel 294 is located below the spraying channel 293. A partition strip 8 located between the spraying channel 293 and the drying channel 292 is arranged around on the inner side wall of the annular seat 291. The vertical pipe 211 is connected to the drying channel 292. The spraying channel 293 is connected to a liquid storage tank 296 through a corrugated hose 295 installed with a pump 297. The air extraction channel 294 is connected to the top end of the air storage cavity 28 through a telescopic connection assembly 298.

[0027] As Figure 2 、 3 shown, the liquid storage tank 296 is arranged on the outer wall of the cylinder 24. The corrugated hose 295 is located between the lower ring 25 and the support portion 23. A U-shaped notch 5 for receiving the corrugated hose 295 is provided at the bottom of the side wall of the receiving groove 210.

[0028] As Figure 3 shown, the connection assembly 298 includes a connection channel 2981 vertically arranged in the side wall of the convex seat 22. An L-shaped pipe 2982 with a vertical end inserted into the corresponding connection channel 2981 is provided on the air extraction channel 294.

An outlet pipe 7 is arranged at the top end of the air storage cavity 28. Solenoid valves are arranged at the bottom ends of the intake pipe 6, the outlet pipe 7 and the vertical pipe 211.

[0030] In this embodiment, the cross-section of the air storage cavity 28 is polygonal. The size of the push plate 212 is adapted to the size of the air storage cavity 28. A threaded hole screwed with the screw rod 215 is arranged on the push plate 212. A bearing for fixing the bottom end of the screw rod 215 is arranged on the inner bottom wall of the air storage cavity 28. The top end of the screw rod 215 is connected to the motor II 216 on the top of the mounting plate 21. When the screw rod 215 rotates in the threaded hole to drive the push plate 212 to move up and down, the side wall of the air storage cavity 28 abuts against the side wall of the push plate 212 to prevent the push plate 212 from rotating together with the screw rod 215, so that the push plate 212 can move up and down as the screw rod 215 rotates.

[0031] A turntable 3 is arranged above the base 1. A motor III 9 is arranged in the base 1. The output shaft of the motor III 9 is connected to the middle of the bottom of the turntable 3. A plurality of groups of positioning mechanisms 4 are arranged circumferentially on the top of the turntable 3. The spraying mechanism 2 is located directly above one of the groups of positioning mechanisms 4. The positioning mechanism 4 includes a recessed part 41 arranged on the turntable 3. A support seat 42 extending to the outside of its top is arranged in the middle of the inner bottom of the recessed part 41. The annular seat 291 is located directly above the opening of the recessed part 41 outside the support seat 42. A fixing seat 43 is arranged in the middle of the top of the support seat 42. An airbag I 44 and a bracket 45 for supporting the airbag I 44 are arranged on the top of the fixing seat 43. A groove for accommodating the airbag II 46 is arranged on the top of the turntable 3 outside the recessed part 41. The top end of the airbag II 46 extends to the outside of the top of the turntable 3. A pipeline 47 connecting the airbag I 44 and the airbag II 46 is arranged in the side walls of the recessed part 41 and the support seat 42. A pressing plate 48 is arranged at the bottom end of the cylinder 24 directly above one of the airbag II 46.

[0032] In this embodiment, a threaded hole screwed with the lead screw 26 is arranged on the side wall of the upper ring 25. A bearing for fixing the bottom end of the lead screw 26 is arranged on the support part 23. The top end of the lead screw 26 is connected to the motor I 27 on the top of the mounting plate 21.

[0033] As Figure 3 shown, nozzles 10 connecting the drying channel 292 and the spraying channel 293 are arranged on the inner wall of the annular seat 291. An air collecting hood 11 connected to the air extraction channel 294 is also arranged on the inner side wall of the annular seat 291.

[0034] Working principle of the present invention: The filter housing is buckled on the fixed seat 43 and the airbag I 44 above the support seat 42. The support seat 42 supports the housing, the fixed seat 43 fixes the housing, and the motor III 9 drives the turntable 3 to rotate, so as to drive the positioning mechanism 4 equipped with the housing to rotate below the spraying mechanism 2 for spraying processing work through the rotating turntable 3. When the processing is completed, the turntable 3 rotates to drive the processed housing to rotate out from below the spraying mechanism 2, and then drives the next group of positioning mechanisms 4 and the housing to move below the spraying mechanism 2 for processing work, so as to realize the pipeline spraying work of the housing.

[0035] When the positioning mechanism 4 equipped with the housing to be processed rotates directly below the spraying mechanism 2, the turntable 3 stops rotating. At this time, the motor I 27 drives the lead screw 26 to rotate in the screw hole on the upper ring 25, so as to drive the ring 25 to drive the cylinder 24 to move downward. Finally, the cylinder 24 drives the lower ring 25 to move downward to the top surface of the turntable 3. When the cylinder 24 moves downward, it will drive the corrugated hose 295 to stretch, or drive the corrugated hose 295 to slide downward from the U-shaped notch 5. At the same time, the cylinder 24 drives the liquid storage tank 296 and the pump 297 to move downward. When the cylinder 24 moves downward, it will drive the pressing plate 48 to move downward together. Among them, the ring 25 at the bottom of the cylinder 24 and the pressing plate 48 will contact the airbag II 46 in the positioning mechanism 4 directly below the spraying mechanism 2. When it continues to move downward, it will squeeze the airbag II 46 through the ring 25 and the pressing plate 48, so that the gas inside it is squeezed into the airbag I 44 through the pipeline 47. After the airbag I 44 is inflated, it fully unfolds and contacts the inner wall of the filter housing, so as to play a role of locking and fixing the housing, preventing it from swinging or slipping under the influence of external force during the subsequent spraying process. In the above process, neither the airbag I 44 nor the airbag II 46 is fully unfolded, so as to facilitate sleeving the housing on the airbag I 44 and the fixed seat 43. When the ring 25 and the pressing plate 48 squeeze the airbag II 46 and contact the top surface of the turntable 3, at this time, the side wall of the compressed airbag II 46 wilts and slides into the groove, and at the same time, the compressed part of the gas in the airbag II 46 is squeezed into the airbag I 44, so that the airbag I 44 fully unfolds and locks and fixes the housing on the positioning mechanism 4.

[0036] During the above process, the cylinder 24 in contact with the top surface of the turntable 3, the turntable 3 and the convex seat 22 enclose the filter housing on the positioning mechanism 4 directly below the spraying mechanism 2 in a sealed space to prevent the odor from spreading during the subsequent spraying of the housing. Before spraying, the air storage cavity 28 below the push plate 212 stores gas and is heated by the heating tube 214. During spraying, the motor II 216 drives the screw 215 to rotate in the screw hole on the push plate 212 to drive the push plate 212 to move downward. The downward-moving push plate 212 drives the vertical tube 211 to move downward and at the same time drives the spraying assembly 29 to move downward. Among them, the annular seat 291 on the spraying assembly 29 drives the L-shaped tube 2982 to move downward in the connecting channel 2981 when moving downward. Finally, the annular seat 291 on the spraying assembly 29 sleeves on the top of the housing and slowly moves downward into the opening of the recess 41. During the downward movement of the above spraying assembly 29, the pump 297 introduces the paint liquid in the liquid storage tank 296 into the spraying channel 293 through the corrugated hose 295 and sprays it out by several nozzles 10, so that when the annular seat 291 drives the spraying channel 293 to move downward, the paint liquid sprayed by the nozzles 10 in the spraying channel 293 can cover the entire outer wall of the housing to spray it. During the above process, when the push plate 212 moves downward, it will squeeze the heated gas in the air storage cavity 28 below it, so that the gas is pressed into the vertical tube through the air inlet 213, and then enters the drying channel 292 through the opened vertical tube 211. As the annular seat 291 moves downward, the paint liquid in the lower spraying channel 293 is sprayed out by the nozzles 10 to spray the housing, and the hot air flow pressed into the drying channel 292 from the air storage cavity 28 is sprayed out through the nozzles 10 to heat and dry the sprayed position on the filter housing, avoiding the situation that the sprayed liquid on the surface of the filter housing forms drip-shaped solidified substances due to its own gravity factor without being dried in time after spraying. As the push plate 212 moves downward, a negative pressure will be formed in the air storage cavity 28 above it. At this time, it acts on the lower area of the current spraying position of the housing through the opened communication pipe 2983, connecting channel 2981, L-shaped tube 2982, air extraction channel 294 and air collecting hood 11, so as to play an air extraction role on the unsprayed position of the housing. On the one hand, it can clean the outer surface of the housing, and on the other hand, it can forcibly extract the pungent odor generated during spraying into the air storage cavity 28 above the push plate 212 to prevent a large amount of pungent odor from diffusing after the cylinder 24 is reset to open the housing later.

[0037] After the spraying and drying operations are completed, the motor II 216 drives the push plate 212 and the nozzle assembly 29 to reset upward through the screw 215, and the motor I 27 drives the cylinder 24 to reset upward through components such as the lead screw 26. At this time, the ring 25 and the pressing plate 48 at the bottom of the cylinder 24 are separated from the airbag II 46. Then, part of the gas in the airbag I 44 enters the airbag II 46 through the pipeline 47, so that the airbag I 44 will not lock and fix the housing after releasing part of the gas. Then, it is convenient to remove the housing from the fixed seat 43 and the airbag I 44. At the same time, when the push plate 212 and the nozzle assembly 29 move upward to reset, the solenoid valves on the communicating pipe 2983 and the vertical pipe 211 are closed, and the solenoid valves on the air inlet pipe 6 and the air outlet pipe 7 are opened. Then, when the push plate 212 moves upward, it can squeeze the gas with a pungent smell in the air storage chamber 28 above it into the purification equipment through the air outlet pipe 7 and the connecting pipe connected to the purification equipment for purification treatment. At the same time, a negative pressure will be formed in the air storage chamber 28 below the push plate 212, so that it will draw in the outside air through the opened air inlet pipe 6 into the air storage chamber 28 below the push plate 212 for storage and heating, so as to facilitate the use in the next step. Then, repeat the above steps to process the subsequent products.

[0038] The present invention has been described in detail above, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
