How to properly install a rotary knife on a veneer peeling machine

The correct installation of the rotary cutter should ensure that two conditions are met.

1.Both ends of the rotary knife should be at the same height. And the installation height of the rotary knife should be equal to the h value specified in the rotary cutting process. Specific methods are as follows.

(1) Put the knife into the knife slot and screw on one clamping nut at each end first.

(2) Use an altimeter or a height equal to the centreline height of the card shaft as a standard. By adjusting the supporting screws, the height of the two Swiss knives is higher than the h value specified in the rotary cutting process. No anti-bending pressure roller rotary cutting machine, adjust the support screw in the middle of the rotary knife, so that the middle of the knife blade is 0.1-0.2 mm higher than the two ends. This can be adapted to the wood section of the rotary hour due to the knife bed extrusion of wood section of the bending deformation caused by the uneven thickness of the veneer phenomenon. With anti-bending pressure roller rotary cutting machine, the middle of the blade does not have to raise, and tighten all the nuts.

2. The range of back angle variation should be compatible with the range of spin cut wood section diameters. Specific methods are as follows.

(1).First back the tool bed to a point equal to the maximum diameter of the wood section to be spun (or to a specified position). The initial back angle is then measured with a back angle gauge. If the initial rear angle and the initial rear angle specified in the rotary cutting process does not match, then adjust the eccentric disc through the adjustment device, so that the initial rear angle is equal to the value specified in the rotary cutting process.

(2).Drive the bed forward to a position equal to the diameter of the core (or to a specified bit catch). The final back angle is then determined and the range of change in back angle is observed to correspond to the diameter of the wood section.

(3).If the initial back angle meets the requirements but the final back angle does not meet the requirements of the rotary cutting process, the final back angle must not be adjusted by adjusting the eccentric disc through the adjustment device. Because after adjusting the eccentric disc, the final back angle will meet the requirements but the initial back angle will not meet the requirements again. At this point can adjust the auxiliary slideway tilt angle. If the final back angle is too small, the angle of inclination can be reduced. After the final rear angle meets the requirements, then return to the initial bit he, check the initial rear angle.

In the absence of a back angle gauge, adjust the back angle by experience after changing the knife. When starting to spin cut, pay attention to the smoothness of the knife feed throughout the spin cutting process. Observe the width of the bright part of the blade and wood surface friction, you can determine whether the back angle adjustment is appropriate. General bright part of the width of about 3-4 mm, that the size of the rear angle and the rear angle change range and wood section diameter range is basically adapted to.
