Abstract: A width-adjustable packaging bag shaper, a bag maker, a packaging machine, and a method. The packaging machine including the bag maker, a traction device and a heat sealing device are respectively arranged above the bag maker, and a width adjustment device adjusts the distances between different sub bottom plates in a front bottom plate and a rear bottom plate by using a leadscrew and slide block mechanism, and then adjusts the width of a bottom plate. The leadscrew and slide block mechanism is used as the width adjustment device of the automatic width-adjustable noodle packaging bag shaper system, and four bottom plates are respectively fixed to the width adjustment device, so the leadscrew and slide block mechanism in operation is accurate in range of adjustment, is suitable for various widths of packaging bags, and has very important significance for the three-dimensional shaping effect of the packaging bags.

Abstract: An electrostatic atomization ultrasonic aided low-damage and controllable biologic bone grinding process and device, which solve the problem of debris blockage and have good cooling effect and high operation efficiency. The device includes: a spindle, arranged rotatably; a water-catching grinding tool for grinding a biologic bone, the spindle being connected with the tool through an ultrasonic vibration mechanism, the tool achieving longitudinal and rotary motions under the drive of the spindle and mechanism; a cooling and film forming mechanism on one side of the tool and connected with an ultrasonic generator in the mechanism, a nozzle connected with a medical nano liquid storage cup arranged at the bottom, compressed gas capable of being introduced into the nozzle to perform pneumatic-ultrasonic atomization on a medical nanofluid, the nanofluid being flushed into a grinding zone in droplets for effective cooling and lubrication; and an endoscope on the other side of the tool.
