Abstract

The invention relates to a production process of an impregnated-paper laminated wood floor by a pre-pressuring trough positioning method. The production process comprises the following steps: firstly, molding a pre-pressuring positioning trough on an impregnated-paper laminated wood floor blank; using a process positioning edge of the pre-pressuring positioning trough as a unified process positioning criterion for processing in subsequent working procedures; and adopting a plurality of cutters to concurrently cut sheets. The method effectively improves the product quality, eliminates the use effect influence and the friction damage caused by the uneven heights of chamfer angles of single strip floors in floor-splicing and using processes, prolongs the service life of the floors, improves the production efficiency, saves material resources, reduces the waste loss and decreases the production cost.

Description

Production process of impregnated-paper laminated wood floor by pre-pressuring trough positioning method

Technical field

The invention belongs to master builder's installed floor manufacture of materials technical field, is a kind of production process of impregnated-paper laminated wood floor by pre-pressuring trough positioning method.

Background technology

In known technology, the floor has become a kind of important materials of mating formation in architecture indoor ground, mainly divides solid wood, impregnated-paper laminated wood floor, solid wood is compound and classification such as bamboo-wood floor, connected mode for inlay, joggle etc.Existing impregnated-paper laminated wood floor is to be that the floor of rectangular flat board forms through tongue-and-groove mode inlaying grafting assembly with the surface, and formed floor is smooth plane.For fear of the strip flooring assembly unit to edge fit install, knocking to draw and damage or frictionally damage in the use; In recent years; The strip flooring that has occurred precompressed groove explained hereafter on the market; In the strip flooring assembly unit edge fit is formed the coated arcuation chamfering that the dipping ply of paper is arranged, making has had tangible lifting in outward appearance, quality and the service life of impregnated-paper laminated wood floor.At present, the precompressed groove process of employing is usually, and the sheet material of impregnated-paper laminated wood floor is sent in the hot press, according to the dimensions of strip flooring, between two blocks of adjacent strip floorings, extrudes groove.Then, be benchmark with the side of sheet material one side, monolithic impregnated-paper laminated wood floor blanket is processed in cutting piecewise on the hilted broadsword cutting machine, again blanket is sent in the chase mortise make-up machine, be the moulding that benchmark carries out all side channel tenons with the side of monolithic blanket.The major defect that this process exists is:

(1) because the floor chamfering of impregnated-paper laminated wood floor precompressed groove production technology is that first procedure of the production and processing on the floor is accomplished, guarantee the end product quality of chamfer site, just must be very high to the required precision of floor production and processing subsequent handling.In the prior art; The error of floor burst, fluting tenon and finished product floor plate chamfering generally all is controlled at ± 0.1mm in, it is very big to reach this required precision difficulty, therefore; Not of uniform size the causing of chamfer dimesion that frequent appearance causes finished product floor plate because of the machining accuracy error; The chamfering difference of height of docking plate is excessive when mounted to cause strip flooring, chamfer site quick abrasion in the use, and the service life on floor is short.

(2) for satisfying the needs of strip flooring following process precision, the method that adopts accurate burst, hilted broadsword to cut piecewise in the existing production technology is carried out burst processing, causes production efficiency low; Occurrence of waste is many, and the material resources waste is big, and production cost is high; And because burst is processed and other operation production capacity does not match; Usually need to be equipped with tens of cutting burst equipment, cause the increasing of fixed investment and recruitment quantity, also corresponding increase production cost of products.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can effectively guarantee the floor end product quality, reduce the percent defective in the production process, enhance productivity the production process of impregnated-paper laminated wood floor by pre-pressuring trough positioning method that reduces production costs.

Realize that the technical scheme that the object of the invention is taked is: this production technology is carried out according to the following steps:

(1) makes the blanket of impregnated-paper laminated wood floor according to conventional method; And in the hot press of blanket,, blanket is carried out the graduation of monolithic bar shaped blanket and the mold pressing of precompressed locating slot according to the requirement of floor design specification; Wherein, The precompressed locating slot lays respectively at the position, both sides of blanket burst line of cut, and the both sides of precompressed locating slot are respectively bevel edge and technology gulde edge, and the vertical line angle of technology gulde edge and blanket is β=15～30 °;

(2) blanket of mold pressing is cooled off at normal temperatures after; Delivering to the cutting work station of multi-cutting machine, through the positioning and guiding mechanism of cutting work station feed mechanism, is positioning reference with the technology gulde edge of blanket one side; Adopt the parallel cutting of multitool, carry out the moulding of cutting apart of monolithic bar shaped blanket;

(3) the monolithic bar shaped blanket that will cut apart moulding is sent in the chase mortise make-up machine of floor; And the positioning and guiding mechanism that passes through chase mortise shaping station feed mechanism; Technology gulde edge with any side of monolithic bar shaped blanket is a benchmark; To protruding, the machine-shaping of groove tenon of monolithic bar shaped blanket week side, promptly process monolithic strip flooring finished product.

Process of the present invention is particularly suitable for the processing that the his-and-hers watches mask has the impregnated-paper laminated wood floor of abrasion-proof paper and facing paper, and its beneficial effect is:

1) to the no required precision of burst processing; Like this in the burst manufacturing procedure of floor; Can adopt the synchronous burst cutting of multi-disc, improve production and processing efficient thus greatly, effectively solve fluting operation and the unmatched problem of burst operation production output; Be beneficial to and reduce fixed investment and human input, simultaneously production cost is significantly reduced.

2) through the improvement of technology positioning reference, can realize the minimizing of impregnated-paper laminated wood floor blanket allowance, stop the different phenomenon of finished product floor chamfer dimesion, greatly reduce the processing percent defective of production process, save material resources in a large number.

3) this method can be improved the quality of products effectively, and eliminate that monolithic strip flooring chamfering height in floor assembly unit and the use differs and the friction damage that causes and, thereby prolonged the service life on floor greatly the influence of result of use,
