How to ensure the accuracy and uniformity of veneer thickness when producing the veneer by veneer peeling machine?

 Shandong GEELONG Machinery Equipment Co., Ltd. is a professional complete set of plywood production equipment manufacturer. Our main products include wood log debarking machines, veneer peeling machines, veneer dryers, veneer repair machines, glue mixers, glue applicators/glue spreader, paving lines, cold presses, hot presses, plywood edge saws, sanders, puttying machines, boilers, and other equipment needed for plywood production.

The adjustment of a veneer lathe mainly involves two parts: mechanical adjustment and computer adjustment

I. Mechanical Part

1. Installation:
The veneer lathe must be installed horizontally and not tilted.
2. Lubricate before use :
(1) Lubricate the screw and lead screw by using an electric or manual method to lubricate the oil cup on the screw seat . Keep the oil cup filled with oil.                                      
(2) Dovetail groove or U-shaped groove, add machine oil before use, oil level 2mm.
(3) Stabilizing slider: The stabilizing slider controls the dynamic stability of the tool bed and is manually lubricated.                   
(4) Chain and sprocket lubrication: Use machine oil to lubricate the chain and sprocket during use.

(5) Grease lubrication points: A. Between the auxiliary rail and the bearing, add grease once a day ; B. Add grease to the bearing and bearing housing oil gun hole, add grease once every 15 days; C. Bevel gear, in the bevel gear box, add grease once every 30 days.

(6) Drop: The distance between double rollers and single rollers. The measurement method is the same as that for measuring knife height.

3. Knife height:
(1) The blade height is the vertical distance from the upper surface of the double rollers to the blade tip.
(2) Measurement method: Place the wide side of the ruler against the double rows , and the long front side on the double rollers .

The vertical distance from the bottom edge to the knife.

 

( 3 ) knife blade height value (as reference): 118mm- 120mm       

A. 118mm is the blade height for producing face veneer .
B. 119mm-120mm is the height for producing core veneer.
4. Knife blade gap:
( 1 ) The knife blade gap is the distance from the knife tip to the single roller .
( 2 ) The size of the knife blade gap:
When the roller opening distance on the monitor is 80mm, measure the blade gap ;

Knife blade gap=veneer thickness+ (0.2-0.3mm, usually 0.25 mm )

For example , to cut 1.5mm thick veneer , the knife blade gap should be 1.5 + 0.25 = 1.75mm .

5,Knife slope:
( 1 ) Knife slope is the length of the inclined plane of the knife.
( 2 ) When the knife thickness is 12.7cm, the knife slope is 34cm; when the knife thickness is 16cm, the knife slope is 43cm. Knife tip clamp

The angle is 22°.
