Juice extracting machine for fibrous plant

The juicing machine of fibrous plant is formed from feeding roll, upper press roll and lower press roll which are arranged in the mode of V-shape, a pressure device is used to apply pressure to upperand lower press rolls, and the thickness positions of the roll shells of the upper press roll and lower press roll are equipped with juice-discharging holes which are radially and axially communicated, the surfaces of those rolls are rough, and the side surface of their every V-shaped tooth is equipped with step. Said invention can shorten the thickness of compressed material layer through which the press juice is passed, can reduce the juicing pressure, prolong service life of rolls, and several juicing machines can be arranged in series to increase production capacity.
