Bearing block is installed on leading screw, and the bottom of leading screw is meshed with the turbine in turbine and worm case, the worm shaft in turbine and worm case
It is connected by first shaft coupling with hydraulic motor.
Preferably, the both ends of the lower roll are respectively placed on two second bearing seats, the lower surface of second bearing seat
For inclined plane, be adapted below equipped with italic, the inclined plane of italic with the lower surface of second bearing seat, the vertical side of italic with
The piston rod of hydraulic cylinder is connected, and the horizontal side of italic and the upper surface of fulcrum bearing fit.
Preferably, the worm screw in two turbine and worm casees is connected with each other by second shaft coupling and connecting shaft, is ensured
The both ends synchronization lifting of side roller.
The present invention the course of work be：
The position of lower roll is adjusted according to the thickness of plate, lower roll is clamped plate with upper roller, starts hydraulic motor, drives turbine snail
Bar rotates, and the leading screw being meshed with turbine rotates with, the first bearing seat driving same stepping in side roller both ends on leading screw
Row lift work, realizes the curved operation of volume to plate.
The piston rod elongation of hydraulic cylinder is controlled, promotes italic to be moved to lower roll direction, the inclined plane of italic is by second bearing
Seat and the lower roll jacking being positioned above；When the piston rod elongation of lower roll both sides is different, the both sides rising height of lower roll
Differ, lower roll is in heeling condition, can meet that veneer reeling machine rolls plate of different shapes.
Beneficial effects of the present invention are：
（1）Worm and gear driving leading screw is respectively adopted at the both ends of side roller and rotates by the present invention, realizes the synchronization lifting of side roller
High reliability, mechanical self-latching performance is strong, and the supporting to side roller is rigidity；
（2）The present invention uses big worm gear mechanism gearratio, stable drive, noise small；
（3）The present invention can realize lower roll vertical lifting, WidFin or inclination using a pair of of italic, and setting italic inclination angle is small
Mechanical self-latching can be realized in angle of friction, so as to ensure that supporting of the italic to lower roll is rigid.
（4）Italic can carry out Orthogonal Decomposition to the normal pressure of lower roll so that fulcrum bearing bearing-surface to the normal direction of lower roll about
Beam force reduces, and as supporting member, its structure need not be done too greatly with regard to that can meet bearing strength requirement.
