[0043] At this time, the first electric telescopic rod 31, the second electric telescopic rod 33, the third electric telescopic rod 35, the second motor 37 and the third motor 53 will be started, so that the first electric telescopic rod 31, the second electric telescopic rod 33 and the third electric telescopic rod 35 can be used to adjust the three-dimensional positions vertically and horizontally, and then the two trimming wheel discs 38 can be driven to adjust the three-dimensional positions vertically and horizontally. At the same time, the second motor 37 will drive the trimming wheel discs 38 to rotate synchronously, so that the double sides of the corresponding piano white key to be trimmed can be accurately trimmed, and the waste chips generated by the trimming will be sucked into the chip removal outer cylinder 51 for filtration under the action of the third motor 53 and the air guide blades 54, and during the chip removal period, the next piano white key to be trimmed will be moved to another corresponding feeding clamp frame 28 for clamping and fixing according to the above steps;

[0044] Afterwards, the third motor 53 near the third duct 61 will be turned off, and the two second electric push rods 29 near the trimmed white piano keys will be started again and drive the two feeding clamps 210 to move backwards and reset, so as to remove the clamping of the trimmed white piano keys. At this time, the trimmed white piano keys will fall under the action of gravity. During this period, the third motor 53 and the air guide blades 54 near the fourth duct 71 can introduce filtered air into the fourth duct 71, and then the corresponding filtered air will enter the air supply duct 73 and the air supply nozzle 74. Afterwards, the corresponding filtered air will be discharged by the air supply nozzle 74 and impact the falling white piano keys after trimming, so as to effectively reduce the falling speed of the white piano keys after trimming, and then play a buffering role, further ensuring the automatic and safe falling and collection of the white piano keys after trimming, and then carry out subsequent trimming and other operations of the white piano keys according to the above steps.
