Description

A kind of core-board utilizing artificial bladed saw rim charge to recombinate

Technical field

This utility model relates to wood-based plate manufacturing technology field, particularly relate to a kind of utilize that artificial bladed saw rim charge recombinates thin Woodwork plate.

Background technology

At present, the available timber resources of China is limited, and timber supply and demand contradiction is the most prominent.Artificial board enterprise is to wood The utilization rate of material is relatively low, especially the sheet material enterprise such as plywood, finger-jointed plate and core-board, and its corner saw material is mostly as fuel Or garbage, fail to be used adequately reasonably.

Utility model content

The purpose of this utility model is that the shortcoming and defect overcoming prior art to exist, it is provided that one utilizes wood-based plate The core-board of saw rim charge restructuring.

The purpose of this utility model is achieved in that

The saw rim charge of wood-based plate (sheet material such as plywood, finger-jointed plate and core-board) finished product or semi-finished product is carried out group again Close and structure designs, by techniques such as assembly, precompressed and hot pressing, produce the core-board of a kind of new construction, timber can be improved Utilization rate 3～4%, available surface quality and the restructuring core-board product of excellent in mechanical performance while economizing on resources.

This utility model solves the technical scheme that its technical problem is used:

One, the core-board (being called for short the core-board of restructuring) that artificial bladed saw rim charge is recombinated is utilized

The core-board of this restructuring includes sheet surface layer, the 1st middle layer plate, element central layer, the 2nd middle layer plate, bottom plate, laterally saws limit Billot and longitudinally saw trimmings；

Its annexation is:

From top to bottom, sheet surface layer, the 1st middle layer plate, element central layer, the 2nd middle layer plate and bottom plate are sequentially connected with；

Described plain central layer is combined with longitudinally saw trimmings by laterally sawing trimmings.

Two, the production method (abbreviation method) of the core-board that artificial bladed saw rim charge recombinates is utilized

This method comprises the following steps:

1. after impregnation, by the 1st middle layer plate lower surface and the 2nd middle layer plate upper surface through glue spreader cloth glue, two-sided cloth glue amount It is 300～350g/；

2. recombinate on the glue-line of the 2nd middle layer plate, mat formation and laterally saw trimmings (6) and longitudinally saw trimmings (7) as element Central layer, wherein, the width of edge strip is the width of element central layer, and the trimmings number of combinations ratio in direction in length and breadth is for 2:1, And alternately arranged, the plain central layer completing required breadth is mated formation.After having mated formation, the 1st central layer rubberised layer is covered on element central layer, Element central layer is made to be fixed in the middle of the 1st middle layer plate and the 2nd middle layer plate.1st, plywood assembly followed by 2 middle layer plates and element central layer assembly Symmetry principle, forms three-ply board after assembly；

3., after three-ply board assembly completes, pre-pressing stage, pressure 0.5～1.0MPa, time 1.0～1.5 hours are entered；

4. through surface-defect repairing after three-ply board precompressed, enter hot press period, temperature 105～110 DEG C, pressure 1.0～ 1.5MPa, time 8～10 minutes；

The most then carry out Puttying filling-in, sanding, three-ply board upper and lower surface gluing and form five folders with table, bottom plate assembly Plate；

It is the most finally five-layer plywood base hot pressing, temperature 105 DEG C～110 DEG C, pressure 1.0～1.2MPa, time 3～5 minutes, warp Cross saw sand, check qualified, be the core-board of restructuring.

Compared with prior art, this utility model has following advantages and a good effect:

1. a large amount of discarded limit that the processing such as plywood, finger-jointed plate, core-board and solid wood furniture sheet material produce is made full use of Corner saw material, can improve timber utilization rate 3%-4%；

2. owing to the thickness specification of edge strip is unified and its internal stress of rim charge after secondary operations greatly reduces, sheet material after restructuring Surface quality and flatness good, its percent ripple≤0.3mm, angularity≤0.2% after sanding；

3. the cost of product is relatively low, about the 50% of the most common core-board.
