MECHANISM FOR ADJUSTING POSITION OF PRESSURE ROLLERS RELATIVE TO PRESS-SHAPE OF PRESS-PELLETIZER Russian patent published in 2020 - IPC B30B11/20 B30B15/14 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in pelletizing presses having two pressure rollers for press-through of the material through the mould oppositely mounted on eccentric axles on the fixed shaft. Roller position control mechanism comprises reduction gear with housing and two extending spindles, which act on rollers by means of rotary levers. Each rotary lever is connected with eccentric axis for its rotation depending on spindle position. There is holder of pressure rollers rigidly connected with fixed shaft and having holes. One end of the eccentric axles is connected to the fixed shaft and the other end is installed in the holder hole. Housing of the reduction gear is rigidly fixed on the holder. Each spindle is connected to the pivoted lever by means of a two-axis hinge. Free end of the spindle is connected to one axis of the hinge, and a rotary lever is connected to the other axis with possibility of rotation around it, which is rigidly connected to the end of the eccentric axis of the corresponding roller.

EFFECT: higher reliability of adjustment mechanism.
