The present invention relates to a device manufactured by using a natural fiber paper mulberry. More specifically, the present invention is a bulk paper mulberry bast fiber production device can be produced (1) by using a roll-type paper extracted by homogenizing the bast fibers of bast fibers of high quality from the paper mulberry in the automatic production process, receiving a liquid therein body 100 for; And the main body 10, a plurality of blades 111 are installed at equal intervals on the upper rotary drum so that the fiber sheets cut to split the paper mulberry is 3-6cm cutting repeatedly (110); And is installed on the front of the rotary drum 110, the rotation is rotated at the same time as the rotation of the drum 110 is rotated to evenly the fiber sheet roller (120); And the rotation roller 120) and the rotary drum 110, a driving means for driving (200); And consists of a tensioning device 300 for adjusting the tension of the rotating roller. ; 展开▼
