apparatus for regulating the angle of inclination of a schaberblad foer f103

摘要

An apparatus for controlling the tilt angle of a doctor blade (12) includes two support blocks (2) of a doctor blade supporting beam (7), a first actuator (3, 4) by which the supports (2) are movable about on their bearing points (1), a blade supporting beam (7) pivotally mounted between upper parts of the support blocks (2) having a doctor blade (12) attached to the beam, and a second actuator (11) by which the blade supporting beam (7) is movable about on its pivoting point (8) in order to control the tilt angle and loading of the blade (12). Between the support blocks (2), an axle (28, 41) is pivotally mounted which is arranged via a transfer apparatus to rotate essentially in the same way as the blade support beam (7), at least one guiding member (24, 42) is eccentrically attached to the axle (28, 42), and the first actuator (3, 45) is arranged to rest against the guiding member ( 24, 42), whereby the eccentricity of the guiding member (24, 42) causes the rotation of the supporting blocks about the bearing points (1), when the blade supporting beam (7) is rotated around the bearing point (8) with the help of the second actuator (11) whereby it is possible to maintain a constant tip angle during any changes in the blade loading.
