A noise control circuit of a switching mode power supply is disclosed. The switching mode power supply has a primary switch, a secondary switch and a transformer with a primary winding and a secondary winding. The noise control circuit includes a reverse noise generating circuit having a first input terminal coupled to a first pulse terminal or a second pulse terminal of the primary switch, a second input terminal configured to receive an adjusting signal, and an output terminal configured to provide a noise control signal. The secondary winding has a first terminal and a second terminal. The noise control signal is coupled to either terminal of the secondary winding of the transformer.

Noise control circuit for a switching mode power supply and a method thereof

A roller-type conveying device for fruit and vegetable sorting includes a chain assembly and a conveying unit. Fruits and vegetables are placed on the conveying unit. The chain assembly includes a drive chain and a chain support bar, and the drive chain is arranged on the chain support bar. A conveying unit is arranged along a drive chain. The conveying unit includes outer rollers, a roller frame, pin shafts, rubber bushings, a roller shaft, and a support base. The two outer rollers are fixed coaxially on the two ends of the roller shaft. The roller shaft is equipped with the rubber bushing. The roller shaft is movably fitted into a special-shaped hole slot on the top of the roller frame. The roller shaft is arranged axially perpendicular to the transmission direction of the drive chain. The support base is mounted on the drive chain.
