Abstract
The invention discloses a transmission device for a stitch cam and a hanging mesh and needle pressing leg in a flat knitting machine. The transmission device is carried on the nose of a flat knitting machine, and comprises a driving mechanism, a stitch cam mechanism and a hanging mesh and needle pressing leg mechanism, wherein all the mechanisms are mounted on a triangular mother board, and the driving mechanism drives transmission of an internal gear and an internal rack, so that the stitch cam, a hanging mesh pressing leg and a needle pressing leg are driven to do corresponding movements. When the transmission device works, a driving gear is driven to rotate at first under the drive of a stepper motor, so that the rack is led to displace, the stitch cam is moved to the working position, and the stitch cam is returned by utilizing the resilience force of a stitch pressure spring; meanwhile, a leg pressing rack is led to displace leftward and rightward under the action of a lower stitch rack, and finally the hanging mesh pressing leg and the needle pressing leg are driven to move. According to the invention, the driving method is simple and effective, which is different from the single electromagnet control before, so that no more components and parts are required, therefore, a large amount of consumption is reduced in the aspects of economy, manpower and the like.
