      Plywood veneer peeling machine is one of the main equipment for the production of plywood. The plywood veneer peeling machine(rotary cutting machine) is used to process wood segments of a certain length and diameter into a continuous veneer strip for the production of plywood, fine wood top boards and other wood-based panel veneers. The appearance of the plywood veneer peeling machine(rotary cutting machine) not only improves the quality and precision of the production veneer, but also greatly improves the production efficiency and the degree of automation of the whole machine. The plywood veneer peeling machine(rotary cutting machine) is divided into two types:a  spindle plywood veneer peeling machine and spindleless plywood veneer peeling machine(plywood veneer rotary cutting machine). The spindle plywood veneer peeling machine is suitable for large diameter wood, and the spindleless plywood veneer peeling machine(plywood veneer rotary cutting machine)  is suitable for small diameter wood. Let's first take a look at the solutions to the problems encountered by the spindle plywood veneer peeling machine at work.

Let's first understand the rotary cutting method with the spindle plywood veneer peeling machine: the left and right card shafts clamp both ends of the wood segment and drive them to rotate. The blade of the rotary knife installed on the knife bed is parallel to the axis of the card shaft and feeds along its vertical direction. Cut out veneers of equal thickness along the direction of the annual rings of the wood segment.

1, veneer roll:

This situation is generally mainly caused by the knife door of the spindle plywood veneer peeling machine(spindle rotary veneer peeling machine) being too narrow or the knife holder being too high. The solution is very simple. Loosen the ram screws and adjustment screws on both ends, widen the knife door, lower the height of the knife, and then tighten the screws, so as to solve the problem of veneer rolling.

2. Uneven thickness of veneer:

Mainly due to damage to the distance measuring or speed measuring encoder or electronic ruler of the spindle plywood veneer peeling machine(spindle rotary veneer peeling machine). Solution: adjust the fast-forward frequency of the rotary cutter to 2Hz, and observe whether the diameter of the log changes continuously. If there is still a pause, it means that the ranging encoder is broken and needs to be replaced. If the speed of the roller is inconsistent with the actual speed, the speed encoder needs to be replaced.

3. The peeled veneer is wavy:

This situation is generally caused by the excessive resistance of the feed of the spindle plywood veneer peeling machine(spindle rotary veneer peeling machine). Solution: Check whether the current output by the inverter is greater than 5A when idling. If it exceeds the need to adjust the machine, check whether the resistance caused by poor lubrication is too large.
