Problems solved by technology

[0003] At present, there are some defects in the production process of plywood, which leads to insufficient strength of plywood, deformation of plywood, poor surface effect of plywood, and poor bonding effect between plywood. During the repair process, The firmness between the repairing compound used and the plywood is not strong, resulting in the problem of falling off of the repairing compound

Embodiment 1

[0035] A processing method for plywood, comprising the steps of:

[0036] Step 1, select the raw material: the raw material is the log made from poplar felling;

[0037] Step 2, sawing wood: according to the size of the plywood to be made, use a sawmill to perform sawing operation on the round wood in step 1, and set up a block around the sawmill to ensure the safe operation of the sawing process;

[0038] Step 3, log peeling: Use a rounding machine to find rounds on the logs sawed in step 2, and the rounding machine cuts off the bark on the surface of the logs to obtain round logs with a smooth surface;

[0039] Step 4, rotary cutting: Use a rotary cutting machine to peel the round wood in step 3. After rotary cutting, veneers with the same size are obtained, and then let the veneers dry naturally;

[0040] Step 5, the first gluing process: take the veneer after natural drying in step 4 and use a gluing machine to perform double-sided gluing to obtain a double-sided gluing b...

Embodiment 2

[0054] A processing method for plywood, comprising the steps of:

[0055] Step 1, select raw materials: the raw materials are logs made from eucalyptus felling;

[0056] Step 2, sawing wood: according to the size of the plywood to be made, use a sawmill to perform sawing operation on the round wood in step 1, and set up a block around the sawmill to ensure the safe operation of the sawing process;

[0057] Step 3, log peeling: Use a rounding machine to find rounds on the logs sawed in step 2, and the rounding machine cuts off the bark on the surface of the logs to obtain round logs with a smooth surface;

[0058] Step 4, rotary cutting: Use a rotary cutting machine to peel the round wood in step 3. After rotary cutting, veneers with the same size are obtained, and then let the veneers dry naturally;

Abstract

The invention discloses a method for machining plywood. The method for machining the plywood comprises seventeen steps including selecting raw materials, sawing wood, debarking round wood, conductingrotary cutting, a first laminating procedure, arranging slab, a first pre-pressing procedure, a first hot pressing procedure, surface finishing, surface sanding, a second laminating procedure, cladding, a second pre-pressing procedure, a second hot pressing working procedure, edge-sawing, detecting and packaging. According to the method for machining the plywood, in the pre-pressing procedures andthe hot pressing procedures, parameters and time are strictly controlled so as to improve the quality of plywood and to avoid the situations that gluing between the plywood is poor and the plywood has foams; manual pressure relief is carried out, so that the phenomenon that the plywood has the foams due to direct pressure relief is avoided, and the defective rate of the plywood is reduced; strictquality control is carried out before the plywood leaves the factory, so that the plywood with poor quality is prevented from entering a market, and the quality of the released products is guaranteed; and each step is completely implemented, so that the plywood with excellent quality is obtained.

Description

technical field [0001] The invention relates to the technical field of plywood manufacturing methods, in particular to a processing method of plywood. Background technique [0002] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture, and it is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers are usually glued together according to the direction of the wood grains of adjacent layers perpendicular to each other. Usually, the surface and inner panels are symmetrically arranged on both sides of the center layer or the core. The slabs made of c...
