Research on Motion Trajectory Planning of Detaching Roller Based on Hybrid-driven
In view of the current problems such as fixed motion output characteristics and large vibration of the detaching and lapping mechanism of the cotton comber,the detaching and lap-ping process of the detaching roller of the cotton comber is analyzed,and the key displacement position of the detaching roller is determined.Two power distribution schemes of alternating drive and segment drive are proposed according to the motion law of the differential gear train.The cubic spline curve is used as alternating driving displacement curve,and the S-shaped accel-eration and deceleration curve is used as segment driving displacement curve.Through compar-ative analysis,the best detaching roller motion trajectory is obtained.It is pointed out that when the length of cotton fiber is set to 30 mm,both the two driving schemes can meet the require-ments of detaching and lapping;the high-speed forward and reverse motion of the detaching roller is decomposed by the hybrid-driven mechanism,and the servo motor hybrid-driven detac-hing roller is realized,and its motion performance is better.
