Stick it in based on physical analysis of mechanical properties on the basis of the scientific design. Through extrusion, cut, scratch, such as a continuous process to fight to achieve the complete stripping system ramie process. The working principle for the pressure rollers are still squeeze, cut and scrape peeling drum beat Ma. However, in specific institutions and the drive to improve the design and innovation. Changes in regulation of the installation of pole position and structure to make appropriate changes so that the adjustment guide plate wider; Learn from that part of food machinery to increase the gear linkage backlash transfer can be processed to adapt to changing environment; Ma cutting blade simplifies the complexity of the process of direct pressure in the secondary roller design hob, easy to implement features. Design principles focus on practical considerations, economic principles, preferred standard parts common priority with the tolerance, the source of a wide range of engineering materials. Lower manufacturing costs, improve agricultural extension in rural areas, the face to break the status quo of China's farm machinery for farmers benefited.
