Background

The rotary cutter is used for processing wood sections with certain length and diameter into continuous veneer strips for producing veneers of plywood, veneers of fine wood and other artificial boards. The main technical parameters of a rotary cutting machine are the maximum length and the diameter of the wood sections which can be processed. The rotary cutter is one of the main equipments for producing plywood, and is divided into a cutting machine with a rotary cutter and a rotary cutter without a rotary cutter, and with the technological progress, a digital servo control technology is also applied to the production of the rotary cutter, and in recent years, numerical control rotary cutters appear. The appearance of the numerical control rotary cutter not only improves the quality and the precision of the produced veneer, but also greatly improves the production efficiency and the automation degree of the whole machine. The numerical control rotary cutter without clamp is an important device on a plywood production line or a veneer production line, and is mainly used for carrying out secondary utilization on the residual wood core after rotary cutting by the rotary cutter with a clamp shaft, and rotary cutting the wood sections with different lengths and the wood core within a certain diameter range into veneers with different thicknesses, wherein the rotary cutting diameter is small. The rotary cutter is used for rotary cutting the wood sections into single plates. The general method of rotary cutting is: the left and right clamping shafts clamp two ends of the wood section and drive the wood section to rotate, the cutting edge of a rotary cutter arranged on the cutter bed is parallel to the axis of the clamping shafts and performs feeding motion along the vertical direction of the clamping shafts, and veneers with equal thickness are cut in a rotary manner along the annual ring direction of the wood section.
