Abstract
The invention relates to a production process of a laminated material. The production process comprises the following steps of: material preparation, sheet drying, smoothening of two sides in the thickness direction, material selection and cutting, finger-jointing in the length direction, smoothening of four sides, assembly and cold pressing, sanding and trimming, packaging of finished products and warehousing. By adopting the production process of the laminated material, sheets can be dried uniformly, and deformation, cracking and bulging of sheets can be avoided effectively. Moreover, the moisture content of the sheets is low, the drying time is short, the sheets have high bending resistance and tensile resistance, and energy can be saved effectively.
Description
Technical field
The present invention relates to a kind of production technology of sheet material, especially a kind of production technology of integrated timber.
Background technology
At present, because deforestation is comparatively serious, the supply of timber is not enough, causes its price more and more higher, and building and decoration industry begin more use artificial board and replace solid wood.Integrated timber is a kind of of wood-based plate, and than other artificial board, the aspects such as its intensity, bending resistance and stretching resistance have stronger advantage, but compare with solid wood, the integrated timber volume recovery is low, and the cost of product is high, in case quality problems occur, will cause very large loss.
Especially sheet material cold pressing and dry aspect, traditional air pressure board joint method, pressure is less, sheet material is easy to crack, bubble; And the heat that general drying oven produces is inhomogeneous, and drying rate is slow, easily causes the generation of the situations such as the sheet material water content is high, inhomogeneous, thereby makes sheet bending, warp, and affects its use.
Summary of the invention
The production technology that the purpose of this invention is to provide a kind of integrated timber, with solve the sheet material cracking that run in the integrated timber production, bubble, crooked, the problem such as warp.
The technical solution adopted for the present invention to solve the technical problems is: a kind of production technology of integrated timber, comprise the steps: that saw lumber → scrape → select materials in sheet material drying → thickness two sides, fracture → length finger → S4S → jigsaw is colded pressing → and sanding is flush → finished product packing → warehousing.
The drying device that above-described " sheet material is dry " technique adopts comprises drying room, outlet pipe, circulating pump, Self-controlled pump, storage tank, boiler, distribution box, vavuum pump and water inlet pipe; This drying cartridge is equipped with the drying room of an oven dry sheet material, is furnished with heat radiation, drying system in this drying room; Described drying room is connected with outlet pipe with the hot water outlet of boiler by water inlet pipe and is connected with water inlet; On the described water inlet pipe vavuum pump is installed, is connected with circulating pump on the outlet pipe, enter the drying room kiln dried wood to guarantee hot water and steam in the boiler, and make hot water return to boiler, to save water source and heat; Described boiler, vavuum pump and circulating pump are connected to respectively the power supply distribution box; The cold water inlet of described boiler be linked in sequence storage tank and Self-controlled pump, when the discharge reduction of boiler, the water in the storage tank will flow to boiler, and in time for boiler replenishing water prevents its dry combustion method, the while, Self-controlled pump was from the moisturizing of trend storage tank.
Use this drying device to carry out the sheet material drying, the moisture content of sheet material is 5%～7%, is significantly less than state-set standard; Drying time is about 5 days, has shortened drying time, has saved the energy.
The mode that " jigsaw is colded pressing " process using hydraulic pressure among the present invention is colded pressing, larger, more even than the air pressure pressure of colding pressing, can effectively prevent the sheet material cracking, play drum, improved working strength and the stretching resistance performance of sheet material.
The invention has the beneficial effects as follows: the production technology of this a kind of integrated timber, can make sheet material oven dry evenly, have to prevent sheet deformation, cracking, play drum, and the moisture content of sheet material is low, drying time short, counter-bending and tensile property is strong, effectively saved the energy.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing 1 is the example structure schematic diagram of panel drying device.
Among the figure, 1. drying room, 2. outlet pipe, 3. circulating pump, 4. Self-controlled pump, 5. storage tank, 6. boiler, 7. distribution box, 8. vavuum pump, 9. water inlet pipe.
The specific embodiment
The integrated sheet material that is applicable to make stair tread take production is as example, at first with round log through the sport car band saw, main force's pony hand-saw etc. cuts into sheet material; By stifling moisture in the timber and oil content are dried by the fire, sheet material through oven dry after, by double surfacer or planer, thicknesser scraped in the two sides, then by multiple blade saw, with the plate cutting slivering of scraping; The batten of well cutting is screened, select intact material, without blue become, without oily line, without cracking, break section without the batten of scar knot; The batten process of making is dredged tooth, be connected into strip with bonding agent; Through four side moulder the batten that connects is dug into neat square bar; Specification side's bar is pressed into needed sheet material by forcing press; With the sheet material that presses, thicknesser, sanding become needed thickness and repair arrangement, packing warehouse-in.
In accompanying drawing 1, panel drying device comprises drying room 1, outlet pipe 2, circulating pump 3, Self-controlled pump 4, storage tank 5, boiler 6, distribution box 7, vavuum pump 8 and water inlet pipe 9; This drying cartridge is equipped with the drying room 1 of an oven dry sheet material, is furnished with heat radiation, drying system in this drying room 1; Described drying room 1 is connected with outlet pipe by water inlet pipe 9 and is connected with water inlet with the hot water outlet of boiler 6 respectively; On the described water inlet pipe 9 vavuum pump 8 is installed, is connected with circulating pump 3 on the outlet pipe 2, enter drying room 1 kiln dried wood to guarantee hot water and steam in the boiler 6, and make hot water return to boiler 6, to save water source and heat; Described boiler 6, vavuum pump 8 and circulating pump 3 are connected to respectively power supply distribution box 7; The cold water inlet of described boiler 6 be linked in sequence storage tank 5 and Self-controlled pump 4, when the discharge reduction of boiler 6, the water in the storage tank 5 will flow to boiler 6, in time prevent its dry combustion method for boiler 6 moisturizings, and the while, Self-controlled pump 4 was from 5 moisturizings of trend storage tank.
