When the annular air knife 19 reaches the other clamping block 31, the annular air knife 19 is detected by the corresponding photoelectric switch 25, at this time, the photoelectric switch 25 sends a signal to the motor 6 in operation, the motor 6 stops operating, meanwhile, the photoelectric switch 25 sends a signal to the fixed air cylinder 24, the fixed air cylinder 24 releases the segment 30, meanwhile, the fixed air cylinder 24 on the other slide block 22 tightly pushes the segment 30 on the through hole 23, and when the passivation is completed, the clamping mechanism passes through the material inlet and outlet 27 and exits the shell 26; then replacing the new round tube for passivation.
During the next passivation, the spraying process is the same as that described above, and during the uniform scraping process by using the annular air knife 19, when the motor 6 with the bevel gear 16 is running, since the slide block 22 of the fixed segment 30 is changed, the moving direction of the annular air knife 19 is opposite, and the uniform scraping process is performed reversely, when the annular air knife 19 moves to the photoelectric switch 25 corresponding to the other end of the chute 32, the photoelectric switch 25 sends a signal to the fixed cylinder 24 again, the fixed cylinder 24 releases the segment 30, and the fixed cylinder 24 corresponding to the other slide block 22 re-pushes the segment 30; is convenient for scraping evenly next time.
In the utility model, after passivation, the annular air knife reaches the clamping block at the other end.
Utilize the utility model discloses, there is the other usage: after spraying, scraping is carried out, the annular air knife moves to the other end, after the round pipe is taken down, the motor is operated in advance before next round of passivation, and after the annular air knife moves back to the end where the bevel gear is located again, next round of passivation is carried out.
