Description

Method of forming texture on wooden blinds sheet

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of fabricating a louvered component, and more particularly to a method of forming a texture on a wooden venetian blind sheet having a printed pattern texture. fJS3⁄4孜 is not the general type of blinds, according to its opening and closing direction, it is divided into vertical and horizontal. Its structure and its operation mode mainly use the control device to control the blade to be folded to one side or both sides to achieve The function of opening and closing; and, the internal control device can be used to tilt the blade to a suitable angle to adjust the intensity of the light. The current blinds can be divided into wood blades, aluminum strips, PVC plastic sheets or woven materials, etc., and the surface is coated with paint or color; among them, wooden shutters are natural and high-grade. The characteristics of high-end blinds, but because of its own material restrictions, it is limited to the texture of the wood itself, or the coating of pure paint or paint, so the wooden shutters have very high requirements on the quality of the wood itself, and It can only show a monotonous and ordinary effect, and can not meet the needs of people who are constantly pursuing high-end.

Since the consumer is not satisfied with the surface pattern of the wood itself, a process of covering the surface of the wooden blinds with a predetermined pattern and then applying the paint is developed to make the pattern of the wooden blinds break through the chips. The texture is limited by itself, but with more pattern changes. However, because of its poor sticker strength and poor adhesion, surface delamination is prone to occur, and the printed surface is used to cover the surface, making it more difficult to manufacture. High, the end result is unnatural, so it is not popular with most consumers.

Summary of the invention

The present invention is directed to the problems existing in the above conventional techniques, and after an effort to explore and research, provides a

Confirmation The method of forming texture on the wooden blinds sheet solves the problems of high energy consumption, high cost and low production efficiency in the production and processing of wooden blinds in the conventional technology, and in particular, the technique can be used for the inferior wood without pattern. The texture is even formed on the composite composite panel, which greatly protects the endangered species, and the invention improves the strength and luminosity of the wooden blinds, and has better texture and beauty.

The production process of the wooden blinds sheet of the invention comprises the following steps:

The step of obtaining the formed wood piece: cutting the plate or finger jointing material with a multi-piece saw to obtain a piece of wood louver piece of predetermined specifications, and using a planing machine to cut the sides of the piece of wood into an arc;

Sanding treatment step: sanding and sawing the surface of the louver material piece with a sanding machine to obtain a smooth, burr-free sanding sheet;

Upper color step: The surface of the sanding sheet is covered with a base color, and the background color is made of color paste: Paint: Tianna water is prepared by weighting 3~10: 40~50: 40~45, and the bottom color covers the wood itself. Texture and fill the pores of the wood surface;

Printed texture step: Use a metal wheel with pre-engraved texture to fit closely with the same specification rubber wheel, drive the two wheels to rotate in opposite directions, and inject the colorant into the groove formed by the two wheel stickers. Soft, after the surface of the engraved metal wheel is pressed and rotated, the surface forms a printing plate, and after the rubber wheel rotates and sticks the coloring agent in the groove, the wooden venetian blind film which has been coated with the ground color is rolled on the wooden piece. Get the desired pattern texture;

Printing surface treatment step: The wood piece obtained with the desired pattern texture is coated with a paint which increases the transparent three-dimensionality of the surface.

In the sanding treatment step, if a laminated material is used, the gap at the finger joint is filled first, and sanding is performed.

The surface of the sanding sheet has a 240 mesh abrasive belt effect. In the printing texture step, the coloring agent is prepared from a color paste: Tianna water in a weight fraction of 40 to 60 _: 40 to 60.

In the printing surface treatment step, the paint is an ultraviolet curing paint or an environmentally friendly paint. The advantages and disadvantages of the present invention are as follows:

Since the invention combines the formed wood chips, the material sanding treatment, the sanding surface, the printing and the printing surface treatment steps by sawing the wood, the wood blinds with low quality, simple method and low cost are produced. The sheet has a better texture and aesthetics. Especially when the base color is printed with a mixture of raw materials such as gold, silver powder, pearlescent light, bright powder or pigment, the blade can be rotated by angle to adjust the light due to gold or silver powder. Pearlescent and bright powders produce a luxurious and varied effect on the reflection of light. In addition, the background color and the colorant formed by the above ratio by the present invention can greatly improve the coating and the surface of the wood yarn after being coated on the surface of the wood yarn sheet due to the enhanced adhesion of the base color itself and the weather resistance of the colorant. The adhesion between the substrates and the mechanical properties such as flexibility, hardness, impact strength of the venetian blind sheets, and the cost are reduced.

Due to the particularity of the material, the surface printing pattern is a problem. Therefore, most of the current wood surface patterns are made by using patterned stickers and overlying paint. The present invention is proposed by background color covering and texture printing. The combination of steps directly prints the predetermined pattern on the surface of the wood chip, and is superior to the sticker wood chip in terms of the strength of the wood chip, the vividness and the true degree of the texture of the pattern, and the change of the texture is far superior to the coloring of the traditional wooden shutter film. , the effect of painting.

The printing process of the present invention can also be applied to a variety of materials. For wood, it is not only suitable for ordinary wood chips, but also for wood chips obtained by finger-joined laminated materials, but the printing effect is the same. Since the finger jointed laminated materials are mostly bonded with wood trim, the consumption of superior wood is greatly saved. The original ordinary wood blinds film production process, from log processing to finished curtains, the total yield is 25%. After using the wood curtain printing technology, the finger jointing material is used in a large amount, and the output rate is increased. 30%. It not only guarantees the quality and aesthetics of the product, but also saves a lot of resources. Through the method of the invention, the finished product is produced on the wooden venetian blind sheet. In addition to domestic sales, it will be exported to Korea, the United Kingdom, the United States, Japan, Vietnam, Taiwan and other countries and regions, and the annual sales will reach more than 100 million yuan. .
