We know that the shaftless veneer peeling machine
needs to adjust the height of the blade in the machine and equipment when in use.However,many people do not know whether the blade is adjusted to a higher or lower point.Some people even use it for a long time.I haven’t adjusted the height of the knife,so let’s follow the editor to find out in detail whether the knife height of the veneer peeling machine
is high or low.
When the equipment leaves the factory,we have adjusted the height of the rotary cutter.The standard is that the fixed knife bolt under the cutting edge of the rotary cutter is 145mm.In principle,the cutting edge height of the rotary cutting knife should be 0--1mm higher than the center of the log.If the wood trembles during the trial rotary cutting,it means that the height of the knife is low.The blade should be adjusted upwards until the wood does not tremble.If cutting is found during rotary cutting The resistance is too large and the skin is broken,and the obvious white marks under the blade are longer(generally 3--4mm is appropriate),indicating that the blade height is high,and the rotary cutter should be lowered until it is suitable.
When operating the veneer peeler,special attention must be paid to safe operation specifications to ensure that hidden dangers are minimized.
The correct installation of the rotary knife of the veneer peeling machine should ensure that the two conditions are met.The two 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.
The specific method is as follows:
Put the knife into the knife slot,and screw on one clamping nut at each end.
Use an altimeter or a contour device equivalent to the height of the center line of the chuck shaft as the standard,and adjust the support screw to make the height of the two Swiss knife equal to the specified h value in the rotary cutting process(the veneer peeler without anti-bending pressure roller,Adjust the supporting screw in the middle of the rotary knife so that the middle of the blade is 0.1-0.2mm higher than the two ends to adapt to the small rotation of the wood section.The bending deformation of the wood section caused by the knife bed will cause uneven thickness of the veneer.It is anti-bending.The veneer peeling machine of the pressing roller,the middle of the blade does not need to be raised),and tighten all the oysters.
The variation range of the back angle should be adapted to the diameter range of the peeling wood section.
The specific method is as follows:
First,retract the knife bed to the position equivalent to the maximum diameter of the peeled wood section(or a specified position),and measure the initial clearance angle with a reclinometer.If the initial clearance angle does not match the initial clearance angle specified in the rotary cutting process,adjust the eccentric disk through the adjusting device to make the initial clearance angle equal to the value specified in the rotary cutting process.
Move the knife bed forward to the position equivalent to the diameter of the wood core(or a specified position),and then measure the end angle,and observe whether the variation range of the angle is compatible with the diameter of the wood section.
If the initial relief angle meets the requirements but the final relief angle does not meet the requirements of the rotary cutting process,the final relief angle cannot be adjusted by adjusting the eccentric disk through the adjusting device.Because of the adjustment of the eccentric disc,although the final clearance angle meets the requirements,the initial clearance angle does not meet the requirements.At this time,the inclination angle of the auxiliary slide can be adjusted.If the end angle is too small,the inclination angle can be reduced.If the end angle is too large,the inclination angle can be increased.After the final relief angle meets the requirements,return to the initial position and check the initial relief angle.
In the absence of a back angle measuring instrument,after changing the knife,adjust the back angle based on experience.When driving the rotary cutting,pay attention to whether the cutting is stable during the entire rotary cutting process.Observe the bright width of the friction part between the blade and the surface of the wood segment to determine whether the clearance angle is adjusted properly.Generally,when the width of the bright part is about 3-4 mm,it indicates that the size of the back angle and the range of the back angle are basically compatible with the diameter of the wood section.
The above is about whether the blade height of the shaftless veneer peeling machine
is high or low and how to adjust the blade height.From the above content,we understand that it is necessary to readjust the veneer peeling machine
when you buy it.Regarding the height of the knife,adjusting a suitable height can better help us to produce.For those who want to know about the technical characteristics of the card veneer peeling machine,please click to view the detailed article content!
