      We know that the spindleless veneer peeling  machine needs to adjust the height of the blade in the machine when it is used. However, many people do not know whether the blade is adjusted up or down, and some people have not adjusted the height of the knife even after using it for a long time. , let's follow the editor to understand in detail whether the knife height of the spindleless veneer peeling  machine needs to be increased or decreased.

Is the knife height of the spindleless veneer peeling  machine high or low?

We have adjusted the height of the spindleless veneer peeling  machine before leaving the factory. The standard is that the distance between the edge of the rotary cutter and the fixed knife bolt below is 145mm. In principle, the blade height of the rotary cutter is 0--1mm higher than the middle of the log. When the test car is rotary cutting, if the sawdust vibrates, it means that the spindleless veneer peeling  machine axis is high, and the blade should be adjusted upwards until the wood does not tremble. If it is found that the cutting resistance is too large during rotary cutting, the blade of the spindleless veneer peeling  machine without a card axis should be adjusted upwards until the wood does not tremble, and then rotary cutting to avoid wear of the saw blade. The white mark under the knife edge is more obvious (usually 3-4mm), indicating that the height of the knife is relatively high, and the rotary knife should be lowered and placed in an appropriate position.

When operating the spindleless veneer peeling  machine without a card shaft, special attention should be paid to the safety operation specifications, so as to ensure that the hidden dangers of safety are minimized.

The correct installation of the rotary cutter head should ensure that the rotary cutter head meets two conditions: the height of both ends of the rotary cutter head of the rotary cutter without a card shaft is the same, and the installation height of the rotary cutter is equal to the time specified in the rotary cutting process. The specific method is as follows: Put the knife of the spindleless veneer peeling  machine without the card shaft into the knife groove, and firstly tighten the clamping nuts at both ends. Using an altimeter or a height equalizer equivalent to the height of the centerline of the clamping shaft as the standard, by adjusting the support screws, the height of the two rudder knives is equal to the h value specified in the rotary cutting process (for spindleless veneer peeling  machines without anti-bending rollers, adjust the middle of the rotary knife. The supporting screw of the blade is made so that the middle of the blade is 0.1-0.2mm higher than the two ends to adapt to the rotation time of the wood segment. Due to the bending deformation caused by the extrusion of the wood segment by the cutter bed, the thickness of the veneer is not uniform. spindleless veneer peeling  machine with anti-bending roller , the middle of the blade does not need to be lifted), and fasten all the oysters. The range of the rear angle displacement should be suitable for the range of the diameter of the rotary wood segment. The specific method is as follows: first, withdraw the knife bed of the spindleless veneer peeling  machine without the card shaft to the position equivalent to the maximum diameter of the rotary wood segment (or the specified position), and use the measuring A relief angle meter measures its initial relief angle. If the initial relief angle is inconsistent with the initial relief angle specified in the rotary cutting process, adjust the eccentric disk through the adjustment device to make the initial relief angle equal to the value specified in the rotary cutting process. Open the knife bed forward to a position equivalent to the diameter of the wood core (or the specified position), then measure the final relief angle and observe whether the variation range of the relief angle is suitable for the diameter of the wood core.

If the initial relief angle meets the requirements and the relief angle does not meet the requirements of the rotary cutting process, the relief angle cannot be adjusted by adjusting the eccentric disc by the adjustment device. Because of the adjustment of the eccentric disc, although the final relief angle meets the requirements, the initial relief angle does not meet the requirements. The inclination angle of the auxiliary rail can be adjusted at this time. If the final relief angle is too small, the inclination angle can be reduced. If the final relief 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.

Without measuring the relief angle, after changing the tool, adjust the relief angle according to experience. When driving and rotating, pay attention to whether the whole rotating process is stable. By observing the width of the light where the saw blade rubs against the surface of the wood chip, it can be judged whether the rear angle is appropriate. Generally, when the width of the bright part is about 3-4 mm, it means that the size of the relief angle and the variation range of the relief angle are basically compatible with the diameter of the wood segment.

The above is about whether the knife height of the spindleless veneer peeling  machine is high or low and how to adjust the knife height. From the above content, we know that it is very necessary to re-adjust the knife when the spindleless veneer peeling  machine is purchased. Adjusting a suitable height can better help us produce high-quality veneers.
