Each skeleton oil seal is located on the side of the baffle 17 away from the rotating cylinder 14 and abuts against the baffle 17.

[0029] In this embodiment, the number of skeleton oil seals placed on the first conveying belt at one time is equal to the number of sink grooves 16, and the skeleton oil seal corresponds to the sink groove 16 one by one.

[0030] Two mounting racks 4 are fixedly arranged on the lower feeding conveying frame 2, and the two mounting racks 4 are arranged in sequence along the conveying direction of the second conveying belt. The mounting rack 4 closest to the rotating cylinder 14 on the upper feeding conveying frame 1 and the mounting rack 4 farthest from the rotating cylinder 14 on the lower feeding conveying frame 2 are provided with a plurality of drying lamps 9, and the plurality of drying lamps 9 correspond to the plurality of sink grooves 16 one by one.

[0033] The control valve 20 is fixedly arranged on the distribution pipe 7 fixedly connected with the installation frame 4 closest to the rotating cylinder 14 of the discharging conveying frame 2.

[0034] Working principle: before use, the motor 12 is started, the output shaft of the motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the rotating cylinder 14 to rotate. The rotating cylinder 14 drives the flap 15 to rotate, and when the openings of all the sink grooves 16 on one of the flaps 15 are horizontally directed to the first conveying belt, the motor 12 is turned off. At the same time, the control valve 20 is closed.

[0035] In use, the skeleton oil seal is placed between the two partition plates 5 located in the same group. Then the electric push rod 6 is started, the telescopic shaft of the electric push rod 6 is retracted upward and drives the baffle 17 to move upward. When the baffle 17 is completely separated from the skeleton oil seal, the first conveying belt drives the skeleton oil seal to move to the sink groove 16.

[0036] When the skeleton oil seal moves directly below the coating nozzle 8, the suction pump 3 is opened.

[0037] After spraying is completed, the first conveying belt continues to convey the skeleton oil seal to directly below the drying lamp 9, and at this time, the drying lamp 9 is turned on to dry the coating on the skeleton oil seal.

[0038] After drying is completed, the first conveying belt continues to convey the skeleton oil seal. When the skeleton oil seal is conveyed to the end of the first conveying belt, it is slid into the corresponding sink groove 16 through the sliding plate 10. At this time, part of the skeleton oil seal is limited in the corresponding sink groove 16.

[0039] Then the motor 12 is started again, the flap 15 drives the skeleton oil seal to rotate upward away from the first conveying belt through the sink groove 16, and then rotates downward to approach the second conveying belt. In this process, the skeleton oil seal is turned over. At the same time, the electromagnet 19 is started, and the electromagnet 19 magnetically attracts the skeleton oil seal to ensure the stability of the skeleton oil seal during turning over.

[0040] When the skeleton oil seal contacts the second conveying belt, the electromagnet 19 and the motor 12 are closed. At this time, under the action of friction, the second conveying belt drives the skeleton oil seal to move, and when the skeleton oil seal moves to the position directly below the paint spraying head 8 on the distribution pipe 7 fixedly connected to the mounting rack 4 closest to the rotating cylinder 14 on the material feeding and transporting rack 2, the control valve 20 opens the distribution pipe 7, and at this time, the paint spraying head 8 on the distribution pipe 7 sprays the skeleton oil seal after being turned over.

[0041] After spraying, the second conveying belt drives the skeleton oil seal to move to the position directly below the drying lamp 9 on the mounting rack 4 farthest from the rotating cylinder 14 on the material feeding and transporting rack 2, and at this time, the drying lamp 9 is opened to perform drying work.

[0042] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application.
