Abstract
The invention belongs to transmission mechanisms with belt conveying devices, and particularly relates to a driving roll assembly of a double-stroke conveying belt. The driving roll assembly comprises a driving wheel arranged on a driving roll shaft of the double-stroke conveying belt. The driving wheel is in transmission fit with a motor spindle. A wedge block type clutch is arranged between the driving wheel and the roll shaft. The outer ring of the wedge block type clutch and the driving wheel are relatively fixed. The inner ring of the wedge block type clutch and the roll shaft are relatively fixed. When a motor drives the driving wheel to rotate forwards, the inner ring and outer ring of the wedge block type clutch rotate synchronously. When the motor drives the driving wheel to rotate reversely, the outer ring of the wedge block type clutch and the driving wheel rotate synchronously, and the inner ring of the wedge block type clutch and the roll shaft stop rotating. Due to the fact that the wedge block type clutch is arranged between the driving wheel and the roll shaft, the driving wheel can only drive the roll shaft to rotate forwards and cannot drive the roll shaft to rotate reversely, and then the operating reliability and safety of the double-stroke conveying belt are guaranteed.
