Abstract:

Aiming at the problem of the speed limit of the vibration of the mechanical detaching roller drive mechanism of the comber, the scheme of the single-drive detaching roller of the dual servo motor was proposed. First of all, according to the requirement of the combing technology, based on the idea of least square method, a curve was optimized to fit the displacement key points in the moving state of the detaching roller, and it satisfied the rule of the detaching roller motion. Secondly, based on the idea of hybrid-drive, the motion law was reasonably distributed to two power sources. Finally, virtual prototype was established in Adams environment for simulation analysis and was verified by experiment. The research results show that this scheme can accurately realize the motion law of the separation roller. The maximum angular acceleration of the two servo motors decreases by 72.05% compared with that of the single servo motor, which is beneficial to reduce energy consumption. The design eliminates the limitation in speed due to the vibration of mechanical structure. The speed can be adjusted according to different kinds of cotton, which increases the flexibility of the mechanism.
