(1) Always check the feed slot amplitude and coil current. Pay attention to whether the sound of the machine is normal. If the sound is suddenly loudened or if there is a crash, carefully analyze the cause and stop the operation immediately.

(2) The air gap between the iron core and the armature must be balanced at any time. Check whether the bolt is loose and the gap is normal. If the bolt is loose or the spring is broken, the air gap between the iron core and the armature changes. Or hit, deal with it immediately.

(3) Always check if the hoisting device is loose. If the hoisting device is loose, the electromagnetic vibrating feeder will be unbalanced at four corners, which will affect the feeding quality and should be tightened immediately.

(4) The seal cover of the vibrator must be covered to prevent dust from entering, blocking the gap between the plate springs, and frequently cleaning the seal cover for dust.
