Description

Wet and touch wet combining wood skin technique

Technical field

The present invention relates to composite board and paste wooden skin technique, specifically a kind of improve slab and wooden skin bond degree, improve composite board quality stability, extend composite board service life, enhance productivity and reduce the wet of production cost and touch wet combining wood skin technique.

Background technology

The manufacturing process of existing composite board is by carrying out hot pressing formation slab by thick loading cart of mating formation on the conveyor belt fixed after bamboo wood wool mixing glue mixing in small, broken bits being sent into hot press, then roller coating glue on slab, by the veneer of drying, [this veneer is by by wood digestion, then with peeling machine, the timber peeling after steaming is formed the veneer with moisture, by dryer, veneer is dried again] be manually pasted onto on slab, pressed by flatiron.In this process, veneer and slab are all dry, and the bond degree of veneer and slab is determined according to workman's experience, and cause such board quality poor stability posting wooden skin, production efficiency is low.Also make the composite gate quality stability using such board making poor, easily produce deformation being heated in pressurized situation, affect composite gate outward appearance.

In sum, the composite board of prior art pastes wooden skin technique and makes such board quality poor stability, and production efficiency is low and production cost is high.

Summary of the invention

The object of this invention is to provide a kind of improve slab and wooden skin bond degree, improve composite board quality stability, extend composite board service life, enhance productivity and reduce the wet of production cost and touch wet combining wood skin technique.

The technical scheme adopted for realizing above-mentioned purpose of the present invention is: a kind of wetting touches wet combining wood skin technique, wherein: comprise the steps,

First step treatment of mat, forms particle slab by thick loading cart of mating formation on the conveyor belt fixed after bamboo wood wool mixing glue mixing in small, broken bits sends into cold press precompressed;

The process of second step veneer, by timber by precooker boiling, then forms the veneer with moisture by the timber peeling after steaming with peeling machine;

Mat formation on the conveyer belt in glue sprayer front by the veneer of moisture content again, to be delivered in glue sprayer by veneer by conveyer belt and to carry out glue spraying, the veneer after glue spraying exports from glue sprayer;

Veneer after above-mentioned glue spraying is deposited 10 ~ 20 minutes, allows veneer surface moisture natural air drying form finished product veneer;

3rd step is to the process of slab lagging, by on the loading cart on the conveyer belt of the plate blank paving in the first step before hot press, then mat formation at slab upper surface by the finished product veneer in second step, finished product veneer has the plate face of glue and slab upper surface fits; By this loading cart, the slab being fitted with finished product veneer is sent into hot press hot pressing again and form belt leather sheet material;

In described second step, the veneer of moisture content is mated formation on the conveyer belt in glue sprayer front, before veneer be delivered in glue sprayer carried out glue spraying by conveyer belt, namely before the entrance of glue sprayer, air-heater is provided with, this air-heater is positioned at above conveyer belt, dried up by the surface moisture of this air-heater by the veneer of moisture content, the veneer that surface moisture is dried carries out glue spraying by tape transport to glue sprayer.

Due to above-mentioned technique, have moisture, have moisture in finished product veneer before the hot pressing of particle slab, being formed when fitting and wet touching wet, after making hot pressing, veneer and particle slab are integrally formed composite board slab; Improve the bond degree between veneer and slab, by hot press hot pressing, isostasy, effectively improve composite board quality stability, also just extend the service life of composite board, owing to being hot pressing formation composite board, at the bottom of energy consumption, improve production efficiency and reduce production cost.

Detailed description of the invention

Below in conjunction with embodiment, the invention will be further described:

A kind of wetting touches wet combining wood skin technique, wherein: comprise the steps,

First step treatment of mat, forms particle slab by thick loading cart of mating formation on the conveyor belt fixed after bamboo wood wool mixing glue mixing in small, broken bits sends into cold press precompressed;

The process of second step veneer, by timber by precooker boiling, then forms the veneer with moisture by the timber peeling after steaming with peeling machine;

Mat formation on the conveyer belt in glue sprayer front by the veneer of moisture content again, to be delivered in glue sprayer by veneer by conveyer belt and to carry out glue spraying, the veneer after glue spraying exports from glue sprayer;

Veneer after above-mentioned glue spraying is deposited 10 ~ 20 minutes, allows veneer surface moisture natural air drying form finished product veneer;

3rd step is to the process of slab lagging, by on the loading cart on the conveyer belt of the plate blank paving in the first step before hot press, then mat formation at slab upper surface by the finished product veneer in second step, finished product veneer has the plate face of glue and slab upper surface fits; By this loading cart, the slab being fitted with finished product veneer is sent into hot press hot pressing again and form belt leather sheet material.

For ensureing that glue effectively sticks to the surface of the veneer of moisture content, in above-described embodiment, preferably: in described second step, the veneer of moisture content is mated formation on the conveyer belt in glue sprayer front, before veneer be delivered in glue sprayer carried out glue spraying by conveyer belt, namely before the entrance of glue sprayer, air-heater is provided with, this air-heater is positioned at above conveyer belt, dried up by the surface moisture of this air-heater by the veneer of moisture content, the veneer that surface moisture is dried carries out glue spraying by tape transport to glue sprayer.In this embodiment, air-heater only carries out evaporation process to the surface moisture of veneer.

For ensureing finished product veneer and slab adhesion stability, in above-described embodiment, preferably: in described second step, veneer carries out glue spraying by glue sprayer, and glue spraying amount is 80 ~ 130 grams/cm.
