Abstract:

A large number of knitting cycle channels and density adjustment device units make some problems as density of motor driver’s wires which routing is complex easily mutual interference and the late maintenance being not convenient and so on. For these problems, a new structure design which is called inner embeds driver for Knitting Mechanism's density adjustment device is described: The motion controller, driving amplifier, feedback device is highly integrated on a circuit board. By making this board embedded in the motor driver’s body to realize the integrated design. Upper-computer control the stepper motor by CAN bus. Then the stepper motor drives an offset roller CAM mechanism. By this course realized the adjustment of the density triangle. The paper presents with structure design, hardware design, software development in detail. Proved by field test, the device is driving stably and reliably. At the same time it also effectively avoids the difficulty of routing, the installation and the maintenance.

Key words: density adjustment device, inner embeds drive, CAN bus, motor for density adjustment
