The control system intelligently controls the powder feeding of the powder feeding barrel 20 and the powder feeding stopping according to the parameter data of the first probe 221 and the second probe 222, which is beneficial to improving the powder feeding efficiency of a powder feeding center, specifically, when the powder level is lower than that of the second probe 222, the second probe 222 sends a powder feeding signal to the control system, the control system controls the powder discharging valve 81 and the vibrating mechanism 82 of the powder feeding hopper 80, the vibrating screen 70 and the second air film valve to be opened to start the powder feeding work, when the powder level is higher than that of the first probe 221, the first probe 221 sends a powder feeding stopping signal to the control system, and the control system controls the parts related to the powder feeding to stop working; it should be emphasized that, when the control system detects that the third cylinder is in the retracted state and the second probe 222 sends the powder adding signal to the control system, the control system controls the above-mentioned components related to the powder adding to start working, when the third cylinder is in the extended state, no matter what kind of signal the second probe 222 sends, the powder adding component does not work, if the third cylinder is not set in the apparatus, and the powder supplying barrel 20 is moved manually, the first probe 221 and the second probe 222 are set to be electrically connected with the control system in a pluggable manner, so as to avoid the powder adding induction when the powder supplying barrel 20 is in the cleaning and recovering state.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
