the spindle-less wood veneer peeling machine common fault and adjustment methods

We often encounter such problems in the use of the spindle-less wood veneer peeling machine with veneer production process，now following the spindle-less wood veneer peeling machine Frequently problems and solutions:

1 fault: uneven skin.

Reason: poor knife straightness, excessive tolerance of the roller beating, excessive pressure, serious yin and yang wood, wood is too thin and curved.

Remedy: Resharpen the tool, check the straightness of the blade. Such as roller beating can check the bearing is damaged or radial clearance is too large, check the roller shaft head parts due to wood bending or oblate extrusion pressure is too large and deformation, thus affecting the flatness of the skin, if the beating Timely replacement of new flower roller or self-correction. If the knife is too low or the knife is too small, single and double roll and knife pressure on the wood is too large, but also can cause irregular deformation of wood directly affect the flatness of the skin. Specific measurement methods, please read the knife position measurement method map.

When the wood is too thin and bent, the wood will be forcibly straightened and sheared because of the powerful auto-feeding pressure during the peeling process. When the wood is cut out of the machine, the wood will shrink as the original bending shrinks Uneven. Wood in the growth process or long time storage there will always be a positive and negative aspects of the characteristics of the yam, so the density of wood on both sides and the degree of dry and wet, resulting in rotation out of the board flatness vary, so the election is also a wood The essential.

2 fault: uneven skin.

Reasons:  knife position is not correct, the knife is not sharp, knives too small or too large. Excessive dry wood or hard, electromagnetic clutch brush virtual access, knife blade on both sides of the adjustment gap properly.

Remedy: Resharpen the tool sharply and grind it with Whetstone. When the tool bit is too high, the knife seam is too large, the wood will be beating when the remaining small beating, the board surface shape of the curtain, and the wooden core was a square or hexagonal. When the knife is too low or the knife is too small when the wood to withstand squeezing pressure than the normal peeling a few times higher than the screw out of the plate shrinkage caused by ultra-poor surface uneven. When the machine rotary cut sometimes appear when the automatic feed into the stop. Generally only need to rotate the carbon brush down one or two times, such as the lack of oil into the oil tank to clean the thin oil, so as not to clutch the clutch or slipping. Rotary cutting wood if the knife has the amount of rocking can also cause poor uniformity of the board, the adjustment method is: the fastening parts of the screw inspection and fastening, the pressure on both sides of the slider and the distance between the slider adjusted to 0.2 ---- 0.5mm, remember not to tune too tight.

3 fault: inconsistent wood thickness of the remaining two ends of the board was fan.

Reason: the height of both ends of the knife is inconsistent, the knives are not consistent at both ends of the knife, single roller bearing damage, screw loose off, razor  knife, the bottom bar, slide rail screws loosening, screw infeed inconsistent.

Remedy: the height of the knife at both ends of the inconsistency will cause the thick side of the thickness of both sides of the thin side, resulting in oblique skin, wooden core big one small. Woody side of the high side of the knife, wooden  knife on the low side of the rough.

Knife inconsistent at both ends of the knife basically inconsistent with the impact of the knife the same, the knife side of the small thin side panels, thick wood shaft, large knife side of the thicker side of the board, wood axis fine. Just knife height, knives seam adjustment can be restored to normal.

Single roller bearing damage in the normal peeling process due to the extrusion of wood to the roller, broken bearing deformation caused by roller bearing damage section knife seam too large, the wood axis will also be thinner.

Knife table under the ram, slide the screw loose, fall will also directly affect the feed imbalance, uneven, the formation of the spindle is inconsistent with the feed is inconsistent, should promptly check the various parts of the screw is loose, fall, each class must be serious and responsible , To promptly replace the damaged and easily damaged, easy to fall off parts of the screws and parts, strictly eliminate the sick work of the machine, so as not to turn a minor problem into a big problem, resulting in downtime and unnecessary losses.

Inconsistent feed, nut wear, loosen the drive shaft screws, so that the separate rotation of the umbrella wheel screw (each pitch 0.8mm) forward or backward the corresponding number of teeth can be.

4 fault: the periodic uneven skin.

Reasons: overweight yin and yang board, knife too low or too high, single or double roller bearing clearance is too large.

Remedy: Correctly adjust the height of the  knife, replace single and double roller bearings.

5 fault: the slab tail at the end of thin.

Reason: the knife is too low, the knife seam is small, need to adjust the knife position.

6 fault: the slab at the end of partial thick and curly.

Reason: knife is too high, knives sewn large need to adjust the knife position.

7 fault: the machine laborious.

Reason: the sliding parts of the lack of oil, the pressure is too large, high knife.

Remedy: Lubricate the sliding parts, reduce the single roller and  knife position.

8 failure: asbestos tile board.

Reason: Knife sewing small, fast feed.

Remedy: Adjust the knife seam, change the feed rate.

9 fault: uneven thickness of the cross section of the slab.

Cause: The blade is not straight.

Remedy: Re-sharpening, with a thin metal or tape to adjust the  knife seam.
