Veneer: edges on both sides of uneven settlement
Veneer: uneven edges on both sides of the solution: the single plate slab on both sides of the Uneven Blade: not straight, single and double roll straightness, knife sharpener knife, single and double roll straightness calibration.
The rotary cutting machine of veneer fan-shaped solution
The rotary cutting machine of veneer fan-shaped solution: wood shaft tapering slab fan: both ends of the cutter height is not the same, the rotary cutter with double roller ends inconsistent gap. Adjust the cutter height, loosen the bolt cutter ram surface wheel, and the fastening bolt.
Veneer thickness uneven and surface is not smooth solution
In the production process of rotary cutting veneer.
Processing method of cross section of uneven thickness: the blade is not straight, knife gap is not consistent; re adjust the knife, knife gap.
The surface is not smooth, knife angle is not correct, the knife is not sharp; processing method: according to the requirements of the degree or re sharpening sharpening stone
How to improve the utilization rate of Eucalyptus Veneer
At present, the main production of Eucalyptus wood furniture board, Eucalyptus plywood, eucalyptus wood substrate and wood core board, the main raw material is a single Eucalyptus veneer. With eucalyptus veneer veneer, Eucalyptus two veneers output rate of about 45%. In order to make full use of the resources and further reduce production costs, we can consider the greater utilization of this part of Eucalyptus two board made of spell neoplasty to do Eucalyptus eucalyptus wood furniture board, plywood, the company production department to arrange a number of workers to repair two eucalyptus veneer board, and made it into Eucalyptus a single plate plate. In this way, the availability of eucalyptus veneer can be increased, and the production cost can be saved.
Rotary cut veneer thickness solution is uneven
Veneer periodic irregular: high or low knife knife, wooden shaft and serious. Excellent wood, single and double roller bearing aging, single and double roll bounce rate is poor, adjust the height of the knife, replace the wood shaft, replace the bearing, replace the single roll.
Plywood veneer production equipment: the difference between the cutting machine and rotary cutting machine
The cutting machine is the main equipment for producing veneer and wood. According to the plane relative to the horizontal direction of movement of the classification is wood planing machine can be divided into vertical and horizontal two categories, according to the direction of relative planing wood fiber length direction perpendicular or parallel, and can be divided into horizontal planer planing machine and vertical planing machine. The size of modern slicer cutting machine is only 1 / 3 plane past, compact structure, light weight, easy installation and debugging; continuous production, saving wood clamping time, high production efficiency; very smooth, almost hear the noise.
Beautiful texture, thin veneer slicer sliced lifelike, but the veneer of the narrow width is about 400 mm or more are required to narrow, mosaic, low utilization rate of wood, and sliced veneer productivity is only about 10%; the only micro planing planing machine veneer slicer, domestic maximum planing width can reach 720mm.
Rotary cutting machine is also one of the main production equipment, in a sense, it is more widely used than the cutting machine. The rotary cutting machine can be divided into two types: concentric rotary cutting and eccentric rotary cutting according to the rotation of the wood segment around its axis. The concentric rotary cutting machine is divided into a rotary cutting machine with a shaft and a rotary cutting machine without a shaft. The eccentric rotary cutting can obtain the beautiful radial pattern, but the productivity is lower than the concentric rotary cutting.
The rotary cutting machine of large volume and complex structure, a veneer lathe machine before need to log log centering, if not start peeling centering, will spin out the intermittent broken veneer veneer or narrow. Broken board or veneer more narrow, sapwood veneer loss of good material more and more, is not conducive to continuous production. Wood bending, irregular cross-section and ends with large head (taper) and so easy to cause the single plate screwed out of waste wood for broken veneer, and when the log diameter is reduced to a certain extent, it cannot continue cutting (residual wood core caused by wood waste). Spindleless veneer lathe can realize the wood core veneer, the first log on a lathe cutting, and then transported to the remaining core wood veneer rotary cutting machine, the wood core can be peeled to the diameter of 25mm, or even smaller.
