4 Feet Spindleless Venner Peeling Machine


      1. The veneer of the spindleless rotary veneer making machine is rolled or unrolled;

Reasons for the failure of the spindleless rotary veneer making machine: 1: the knife gate is too narrow; 2: the knife holder is too high.

Solution: Loosen the ram screws and adjusting screws on both ends of the machine, appropriately widen the knife door by 10 or so, then lower the knife by two millimeters and then tighten the screws on both ends. In addition, spray as much water as possible when the wood is too dry. For a while. When re-spinning, it can basically eliminate the curling of the board.

      2. The thickness of the peeled veneer is uneven and irregular

Reasons for the failure of the spindleless rotary veneer making machine: 1. The distance measuring encoder or the electronic ruler is partially damaged; 2. The speed measuring encoder is damaged.

Solution: 1. Adjust the fast-forward frequency to 2Hz, fast-forward to observe whether the log diameter change is continuous, if there is an obvious pause, please replace the ranging encoder. 2. Measure whether the rotation speed of the roller is consistent with the actual rotation speed. If there is obvious jitter in the measured value, replace the speed encoder.

       3. The thickness of the peeling veneer is uneven and gradually becomes thicker

Reasons for the failure of the spindleless rotary veneer making machine: 1: The wood is hard or has many knots, which makes the inverter's low-frequency torque insufficient; 2. The grid voltage is low.

Solution: 1: Adjust the F6.10 parameter of the inverter to 160 or adjust the front/rear thickness compensation of the controller parameter to a suitable value.

      4.The thickness of the peeled veneer is uneven and becomes obvious wavy

Reasons for the failure of the spindleless rotary veneer making machine: 1. The rotary cutting machine has a large feed resistance; 2. The input of the motor parameters is incorrect.

Solution: 1: The output current of the inverter will not be greater than 5A when there is no load. If the output current is too large, you need to adjust the rotary veneer peeling machine itself, such as enhancing lubrication. 2: Correctly input the parameters on the motor nameplate and then self-learn.

      Why does the spindleless rotary veneer making machine wear out when it is used? How to deal with it?

      One reason is that the thickness of the wood is uneven, the mechanical operation is not continuous, and some of the cut veneers cannot be used.

      Then one reason is that the wood-fixed chuck consumes the end of the machine, causing the blade to become dull, and the running speed will slowly decrease, which affects productivity. Therefore, the spindleless rotary veneer making machine must be regularly inspected and maintained, and parts must be replaced, repaired and maintained regularly, so as to avoid problems.

      Before using the spindleless rotary veneer making machine, you must fully understand the structural performance of the equipment, avoid overloading, stop and check in time when there is a problem, and pay attention to the inspection of each transmission belt, and keep the lubricating oil tank clean.

      To reduce the occurrence of these conditions, we must operate safely during use, save materials, use rationally, and reduce waste of resources.
