Plywood has a very wide range of applications in our lives. The furniture we usually use is made of it. It can also be used to make boxes for aircraft, ships and other fields. For such a wide range of applications, many people think about it. Very interested, I don't know how it is produced. Today, the Plywood Machine Factory will introduce you to the relevant knowledge of plywood.
Plywood is a three-layer or multi-layered plate-like material which is formed by cutting a wooden section into a veneer or by cutting into a thin wood by wood, and then bonding with an adhesive. Usually, an odd-numbered veneer is used, and adjacent veneers are made. The fiber directions are glued to each other vertically.

Plywood is one of the commonly used materials for furniture. It is one of the three panels of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and crates. A set of veneers are usually glued to each other in a vertical direction in the direction of the wood grain of the adjacent layers. Usually, the front and inner plates are symmetrically disposed on either side of the center layer or the core. The slabs which are formed by laminating the veneered veneers in the direction of wood grain are pressed under heating or no heating. The number of layers is generally odd, and a few have even numbers. The difference in physical and mechanical properties between the longitudinal and lateral directions is small. Common types of plywood are plywood, plywood, and the like. Plywood can improve wood utilization and is a major way to save wood. Then the plywood is made of Plywood Machinery. The plywood machine refers to a machine that uses a rotary cutting machine to rotate logs into a single board, and then arranges the veneers vertically in the fiber direction, such as gluing, pressing, sanding, etc. Plywood is an ideal product for a wide range of applications in building templates, interior decoration, various furniture, office supplies, combination speakers, packaging and cloth exhibitions. Plywood machinery is divided according to its process: rotary cutting machine, veneer dryer, glue applicator, pre-press, Hot Press Machine, vertical and horizontal sawing machine, sanding machine, etc.
So how is plywood produced?
The first step in the production of plywood is to perform the rotary cutting. That is to say, the worker cuts the corresponding sheet according to the specified size. This process requires sufficient patience and seriousness, and it is necessary to pay attention to safety when operating the machine. After cutting out the appropriate sheet, the plywood manufacturer needs to apply the glue. Since the plywood is made by gluing the multi-layer sheet, the step of applying the glue is very important. If the glue is not uniform enough or is not strong enough, the quality of the sheet will be affected. Workers are required to clean the board before applying the glue. Manual glue is required where the machine does not reach the glue. After the glue is applied, the sheets are superimposed one by one and extruded, which can deepen the adhesion between the sheets. The final step is to dry and the plate can be used.
The equipment of plywood machinery manufacturers is very widely used in the processing industry, and the most important thing when we use it is the maintenance of the equipment, because it is related to its service life, etc., what should be done for its maintenance?
First of all, we should be aware that the correct operation is the best maintenance for any equipment, because it avoids problems such as wear and tear caused by operational errors. Also pay attention to the environment used when using, avoid using it in a humid environment, it will cause it to rust and so on. Also pay attention to light handling, minimize the pressure and avoid damage to the product, even if the damage can not directly rub the product with hard objects, should be commissioned by professionals. It should be cleaned after use and can be coated with a layer of anti-rust oil.
So for plywood machinery, we need to pay attention to a lot. Of course, in addition to ensuring the quality and effect of its use, safe operation can not be ignored, pay attention to the safety of circuits and operations, and improve the safety awareness of operators.
