Development of inner embeds driver forknitting mechanism's density adjustment device

A large number of knitting cycle channels and density adjustment device units have the problems of much density of motor driver's wires,complexity of routing and inconvenience in maintenance.For these problems,a new structure design called inner embeds driver for knitting mechanism' s density adjustment device is described.The motion controller,driving amplifier are feedback device are highly integrated on a circuit board.By making this board embedded in the motor driver's body,the integrated design is realized.The host computer control the stepper motor by CAN bus.Then the stepper motor drives an offset roller CAM mechanism.By this course,the adjustment of the density triangle is realized.The paper presents structure design,hardware design and software development in detail.It is proved by field test that the device is driving stably and reliably.At the same time it also effectively avoids the difficulty of routing,the installation and the maintenance.
