The utility model discloses a use does:

the biomass fiber strips to be separated pass through the grooves of the strip passing blocks, the collagen fiber strips which pass through are pressed by the pressing blocks, the potentiometer and the rebounding device are composed of the potentiometer and the torsion spring, the torsion spring can ensure that the pressing blocks have certain pressure on the passing collagen fiber strips, and the collagen fiber strips are not uniform, so that the biomass fiber strips can cause the pressing blocks to move up and down when passing through the strip passing blocks, the movement can cause the change of the resistance value in the potentiometer, and the change of the unevenness of the biomass fiber strips can be obtained through the change of the resistance value.

In the uniform and drafting part, the power source drives the synchronous belt wheel and other two synchronous belt wheels to drive the roller to rotate, the linear speed of the roller is higher than that of the roller, so that drafting is realized, and a smaller drafting is realized between the roller and the roller. The unevenness of the biomass fiber strips can be obtained in the detection part, and the distance between the detection opening and the roller is fixed, so that a certain leveling effect can be achieved by changing the linear speed of the roller (changing the front draft ratio between the roller and the roller).

In the four-bar mechanism of the separating mechanism, a driving bar is rigidly connected with a separating piece, the separating piece is a rake with dense needle teeth, and the biomass fibers are separated by the rake because the linear speed of the movement of the rake is higher than the output speed of a front roller.

Through practical tests, the closer the separation point is to the output point of the front roller, the more accurate the gram weight of the biomass fiber is separated. In order to ensure that the separation effect with the highest precision is achieved on the premise of no interference, the motion trail of the separation part is simulated through motion simulation. The distance between the separating part and the drafting part is adjusted by the track to achieve the best separating effect.

When the separation rake takes away the quantitative biomass fiber and moves to approach the position of the switch, the scraper blade rotates downwards, meanwhile, the air inlet blows in the filtered air, the negative pressure can be generated at the position of the feed inlet according to the Bernoulli principle, so that the biomass fiber on the separation rake is sucked away, and the biomass fiber is sent out through the discharge outlet (air outlet). So that the quantitative separation of the whole biomass fiber strip is completed.
