Plywood is composed of veneers. When the rotary cutting machine is rotary cutting veneers, improving the level of rotary cutting technology is the key to improving the yield of veneers. In this paper, reducing the diameter of the wood core and rationally organizing the veneer pick pipeline reasonable determination of veneer thickness and other factors to propose optimization measures improving the veneer output rate is an important measure to rationally utilize wood resources and reduce product costs.
Shi one. Increasing the volume of the rotary veneer and reducing the useless volume (such as reducing the diameter of the wood core) is a an important aspect. Improve the quality of veneer rotary cutting. Reduce thickness deviation, reduce actual thickness and veneer, the difference between the nominal thicknesses is also a major aspect to improve the veneer yield. The wood is spinning it can be divided into four parts.
part 1 :
Due to the irregular shape of the wood segments (the wood segments are bent, sharp shaving and irregular cross-sectional shape of wood segments segment length).
part 2 :
Due to the incorrect installation of the veneer rotary cutter, the height of the knife, the knife seam, and the measurement and installation, the surface of the veneer rotary cutting is uneven and the thickness is uneven. The veneer is too long due to the section (its length is the length of the segment, but its width is less than the perimeter of the stripped segment).
Part 3：
The matching degree of machine setting and electronic control system setting is unbalanced, and the application of high-precision electronic control system and high-precision servo system does not exert its performance.
Part 4 :
The remaining wood core part of the fourth part, generally the diameter of the wood core is25-30mm; but when the diameter of the wood segment is large, the diameter of the wood core must be increased to facilitate rotary cutting.
MINGHUNG MH-VPM4A VPM8A The model effectively solves these problems：
Due to the irregular shape of the log (bending of the wood segments, sharp shavings and irregular cross-sectional shape of the length of the log).
MH-WD4 WD4A WD8 WD8A Type log debarker,The unique design of the log debarker, the center height of the double stick is individually designed, the rotation speed and the log peeling are adjusted, and the peeling of the irregular log is effectively clamped, and the veneer peeling caused by the clamping and rotation at the same time makes the log peeling effect better and more quick. Prevents irregular logs from leaving the machine, causing time loss and waste, and more effectively improves log peeling efficiency.
Due to the incorrect installation of the veneer rotary cutter, the height of the knife, the knife seam, and the measurement and installation, the surface of the veneer rotary cutting is uneven and the thickness is uneven. The veneer is too long due to the section (its length is the length of the segment, but its width is less than the perimeter of the stripped segment).
MH-VPM4A VPM8A The whole machine adopts hydraulic pressure knife (veneer peeling press knife holder) and automatic knife adjustment function. During the production process of the machine, the unique knife box design is used to adjust the height of the knife on the knife box. The height of the back knife is fixed. The system is fixed on the Veneer peeling machine, and is installed on the machine after each time the knife is sharpened by the Knife grinder, which avoids time-wasting and installation errors for workers in the installation and debugging after each sharpening.
Set parameters by numerical control, input PLC directly through the screen, and control the inverter through the PLC system. The inverter controls the stroke of the motor, which truly realizes simple and precise operation.
The matching degree of machine setting and electronic control system setting is unbalanced, and the application of high-precision electronic control system and high-precision servo system does not exert its performance.

4. The remaining wood core part of the fourth part, generally the diameter of the wood core is25-30mm; but when the diameter of the wood segment is large, the diameter of the wood core must be increased to facilitate rotary cutting.
