Description

Complex, floor cutting method

The invention belongs to a method for cutting a wood-based panel lock composite floor board.

Background technique

In the production process of wood-based laminate laminate flooring, a wooden floor substrate must be divided into a plurality of wooden slats of similar specifications to the finished wood flooring, and then each of the slats is milled and grooved into finished wood flooring. In this process, the wood floor substrate will lose some materials. The finished wood floor area is generally about 90% of the wood floor substrate area, and the production cost is high. Some enterprises increase the production rate of the finished wood floor in order to improve the use rate of the wooden floor substrate. The length of the compressed wooden floor lock, which brings difficulties to the installation of the finished wooden floor, and affects the quality; the later use of the slope cutting method and the reduction of the thickness of the saw blade to reduce the consumption of the wooden floor substrate, although can be reduced 1- 2mm loss, but there will be a lot of unnecessary waste, the most important is not suitable for multi-slice saw automatic processing, production capacity is limited, the use of hand saw cutting is easy to produce errors in operation, affecting product quality, not suitable for scale produce.

Summary of the invention

The object of the present invention is to provide an energy-saving processing method for composite wood flooring, which is to improve the effective use area of the wooden floor substrate by changing the original quality of the finished wooden floor without changing the original quality of the finished wooden floor. To play the role of energy saving, environmental protection, resource conservation and cost reduction, and improve the competitive advantage of wood flooring manufacturers.

The object of the present invention is achieved as follows: According to the shape and characteristics of the finished wooden floor lock, the slotting tool is selected, and the slotting tool can be a common flat saw blade or a contour saw blade closest to the forming buckle. Then, the best cutting point is designed on the wooden floor substrate, and the wooden floor substrate is slotted or profiled and slotted by the method of upper and lower misaligned slotting, so that the shape of the upper and lower slots and the shape of the finished wooden floor are locked. The shape is similar, so that the material consumption can be minimized when the wood floor groove is milled, and the actual use area of the wooden floor substrate is improved. The profiled groove cutting method can be performed by a secondary groove method or a single groove method.

The method of secondary grooving is as follows: using the structural features of the wooden floor substrate, the two sides of a wooden floor substrate are respectively cut by the upper and lower offset slots, and are opened by a grooving tool (saw blade or profile saw blade). The groove is cut, that is, a plurality of parallel upper grooves are opened on one side of the wooden floor substrate, and a plurality of parallel lower grooves are opened on the other side of the wooden floor substrate, and the upper groove and the lower groove are mutually displaced in parallel. The depth of the upper and lower grooves is determined according to the actual shape of the finished wooden floor lock, and each upper groove and its adjacent lower groove are a group, and the joint between each of the upper groove and the lower groove is connected. The distance is determined by the distance when the upper groove and the lower groove are misaligned. The width of the joint is 0-5 mm (when the upper groove is offset from the lower groove by a distance less than or equal to the thickness of one blade, no joint is generated). After the upper and lower slots of the wooden floor substrate are opened, the connecting portion can be cut by a cutter. When the connecting width is small, the connecting portion can be slightly bent by mechanical or manual means, so that the connecting portion is naturally broken to form a small strip floor. Semi finished product. Finally, the semi-finished wood flooring is finished by a milling cutter to form a finished wooden floor.

The other is a method of grooving once. · Using the structural characteristics of the wooden floor substrate, the groove is cut at the same time by the slotted cutting method of the upper and lower positions, that is, the upper and lower grooving tools are simultaneously used on both sides of a wooden floor substrate (saw The sheet or the contour saw blade) opens a plurality of parallel upper grooves and a plurality of parallel lower grooves, and the upper grooves and the lower grooves are mutually displaced in parallel. The depth of the upper and lower grooves is determined according to the actual shape of the finished wooden floor lock, and each upper groove and its adjacent lower groove are a group, and the joint between each of the upper groove and the lower groove is connected. The distance is determined by the distance when the upper groove and the lower groove are misaligned. The width of the joint is 0-5 mm (when the upper groove is offset from the lower groove by a distance less than or equal to the thickness of one blade, no joint is generated). After the upper and lower slots of the wooden floor substrate are opened, the connecting portion can be cut by a cutter, and the connection width can also be small. The joint is slightly bent by mechanical or manual means, and the joint is naturally broken to form a wooden floor strip. Finally, the wooden floor strips are milled around the forming cutter to form a finished wooden floor.

Compared with the traditional cutting method and the miter saw method, the traditional cutting method can be applied to the cutting process of the multi-blade sawing equipment, and the production efficiency is high, but the raw material waste is serious. The miter saw method can only be applied to the cutting operation of the single-saw equipment, and the raw material can be partially reduced. Waste, but the production efficiency is relatively low, the energy-saving profile cutting method is suitable for multi-piece slotting tool cutting, and is suitable for single-piece gutter tool cutting, which has advantages in terms of production efficiency and reduction of raw material loss. It is convenient to use. The technology of composite floor energy-saving profiling method changes the traditional one-time sawing method and reduces the waste caused by the one-time sawing and grooving process without changing the original structure of the wooden floor substrate. Can save wood floor substrate loss

3-7%, by the following calculations, it can also be concluded that the width of the wood strip produced after the division of the wooden floor substrate is before milling [the actual width of the finished wood floor (including the width of the groove of A and B) + milling It is necessary to reserve a part of the size (0.5 mm*2)], which is greater than or equal to the actual calculated width of the wooden floor substrate relative to the required specifications of the finished wooden floor, increasing the actual use rate of the wooden floor substrate, and real saving Wood resources, cost reduction, energy conservation and environmental protection.
