NOVELTY - A cutting device consists of a cylinder component, an upper turbine, a lower turbine, a shearing knife, an upper transmission rod, a lower transmission rod, a high-speed motor, a low-speed motor, a controller, a feeding hole and a discharging hole. The controller is arranged outside the cylinder component. The feeding hole is arranged on the side of the cylinder component. The discharging hole is arranged on the side of the cylinder component. The feeding hole is arranged above the discharging hole. The rotating speed of the high-speed motor is faster than that of the low-speed motor. The rotating direction of the high-speed motor is opposite to that of the low-speed motor. The high-speed motor is fixed at the upper end inside the cylinder component. The feeding hole is arranged at the lower end portion of a filter box. The feeding hole is arranged on the side of the cylinder component. The upper transmission rod is arranged below the high-speed motor. USE - Cutting device for preparing graphene-modified polyamide-6 melt direct spinning fibers (claimed) used in pharmacy, medicine and material. ADVANTAGE - The device increases the flowability of the flow, and increases the slurry flow speed difference in the cylinder, so that slurry can be present in the aggregate to obtain effective dispersion, and such a turbine structure, not easy to the turbine surface residual slurry. The lower end of the upper turbine is added with a cutting tool, the high speed motor drives the rotation, and the rotating cutter increases the direction of the cutting slurry, and it also increases the aggregate in the cutting material, thus, increasing the dissolving rate. The added cutter does not need other power distribution machine, the structure is simple, it only needs to increase the length of an upper transmission rod, the gain effect is obvious, the controller is installed outside the cylinder body, the distance between adjacent damping bases is the same, it ensures the relative DETAILED DESCRIPTION - A cutting device consists of a cylinder component, an upper turbine, a lower turbine, a shearing knife, an upper transmission rod, a lower transmission rod, a high-speed motor, a low-speed motor, a controller, a feeding hole and a discharging hole.
