Several common veneer quality problems in the peeling machine
The current peeling machine can peel very thin veneers, but if the machine fails, the quality of the peeled veneers will be affected, and it will also affect the efficiency of production. Therefore, today I will introduce some common I believe it will be helpful to everyone. 1. Veneer rolling: This situation is generally mainly caused by too narrow knife door or too high knife holder. The solution is very simple. Loosen the ram screws and adjusting screws at both ends, widen the knife door, lower the height of the knife, and then tighten the screws. This can solve the problem of veneer rolling. 2. Uneven veneer thickness: Mainly due to the damage of the distance measuring or speed measuring encoder or electronic ruler. Solution: Adjust the fast-forward frequency to 2Hz and observe whether the diameter change of the log is continuous. If there is 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, you need to replace the speed encoder. 3. The veneer cut out is wavy: This situation is generally caused by the excessive resistance of the knife. Solution: Check whether the output current of the inverter is greater than 5A during idling. If it exceeds 5A, the machine needs to be adjusted, and check whether the resistance caused by poor lubrication is too large.
