Abstract: A NMQL grinding device of ultrasonic vibration assists grinding fluid micro-channel infiltration, and solves the problem that nanofluids are difficult to fully infiltrate the grinding zone in the prior art. Fully considers the impact of thickness of undeformed grinding debris on the grinding process and the lubrication state of single grains during material removal in the grinding process, the advantage of ultrasonic vibration assistance on improving the lubri-cooling performance of NMQL grinding is effectively achieved. According to the solution, the device includes an ultrasonic vibration mechanism capable of adjusting the spatial position of ultrasonic vibrators, the mechanism being arranged on a worktable; a NMQL grinding mechanism, arranged above a workpiece fixing table; and a grinding force measuring mechanism, including a dynamometer and a grinding force controller connected with the dynamometer, the dynamometer being arranged at the bottom of the ultrasonic vibration mechanism.

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.
