Research of the Design of Oscillating Collective Doffing Mechanism
In order to promote the digitization process of ring spinning frame,the action realiza-tion and improvement project of the oscillating collective doffing mechanism are briefly de-scribed,and the calculation method of determining the spatial position of long and short rocker by geometric drawing and algebraic method is described in detail.The technical requirements and design points of the oscillating collective doffing mechanism are analyzed from the aspects of the operation accuracy requirements of the bobbin grabber,the accuracy requirements of the lifting arm design,the torque,the pull rod,the oscillating shaft,the center axis of the spindle,the long rocker and lifting arm,center height difference.According to the type of control sys-tem and the trend of digital technology innovation of oscillating collective doffing mechanism,the technological innovation method is put forward.It is pointed out that the oscillating collec-tive doffing mechanism is the key to the continuous and digital production of long spinning frame,which has the advantages of low labor intensity,small labor amount and high doffing effi-ciency.To further improve its stability,reliability and digitalization,it is necessary to underst-and the details of the mechanism,find defects and continuously optimize.
