Wood Working Machine Plywood Machine for Plywood Production
Multi-layer plywood production process
1. The main equipment required for the production of plywood:
1. 2700mm, the whole line of rotary cutting machine.
2. The whole line of 1500mm rotary cutting machine.
3. A knife sharpener.
4. One veneer dryer, customized according to the output of plywood.
5. 1 glue mixer
6. Glue coating machine 1 set 2700mm
7. cold press machine 1set
8. hot press machine 1set
9. Plywood edge sawing machine 1set
2. Production process of multi-layer plywood nine-layer plywood:
Poplar→broken wood→veneer peeling→veneer drying→finishing and repairing veneer→glue mixer mixing ratio→glue spreader gluing and stringing→group embryo board→pre-pressing machine pre-pressing→hot pressing machine hot pressing→plywood saw Edge → plywood inspection → secondary coating → hot pressing → secondary inspection → storage
The specific process flow is as follows:
1. Poplar, beech, birch, eucalyptus, and other woods are classified according to their length and diameter, and then cut into segments with a chainsaw.
2. Use different rotary cutting machines to cut veneer with different thicknesses such as 2.2mm, 1.7mm, 1.5mm, etc.
3. The single veneer is neatly stacked on the tray and transported to the dryer for veneer drying. The temperature in the dryer reaches 120-150 degrees Celsius, and the moisture content of the veneer after drying is less than 10%, and it works continuously.
4. After the dried veneers are stored and stacked, they are sorted, repaired and sorted.
5. Put the different classified veneers into the gluing machine for gluing.
6. Arrange the glued veneers in a criss-cross pattern of plywood embryos (5 layers, 7 layers, 9 layers, 12 layers), and the thickness is assembled and arranged according to the thickness of the plywood. The thickness of the plywood is as follows:3mm, 6mm, 9mm, 12mm, 15mm, 18mm, 25mm, 28mm, etc.,
7. The semi-finished plywood after grouping is pre-pressed, and the pre-pressed plywood is easy to be hot-pressed and not easy to dislocate.
8. Put the pre-pressed semi-finished plywood into the hot press for high temperature hot pressing. The temperature of the hot pressing plate of the hot press is 120-130 degrees Celsius, and the pressure is adjusted according to the pressure of the hot press.
9. Saw edge processing according to the size of the finished heat press
10. The quality inspection is carried out according to the samples of the sawn plywood products. The inspection content usually includes the plywood front degree, the plywood water resistance test, the plywood surface is required to be smooth and flat, the thickness is uniform, and the four sides are straight at a 90-degree angle, etc.
