Description

Technical Field

[0001] The present invention relates to the technical field of wood processing, and specifically to a method for making 3D wood textures and patterns. Background Art

[0002] Solid wood bending refers to a method of bending wood into a desired shape through softening treatment and pressing. The curved parts made by this method have natural and smooth lines, beautiful shapes, good strength, save labor and materials, and can retain the rich natural texture and color of the wood, so it is widely used in actual production.

[0003] The existing solid wood bending technology in the prior art is mainly used to make simple bent parts with a single shape and lack of artistry. Moreover, the bending process mainly changes the shape of the wood, and has limited impact on the wood texture, unable to meet people's requirements for beauty and personalization. For this reason, a method for making 3D wood textures and patterns is proposed.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present invention. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is to propose a method for making 3D wood textures and patterns.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A method for making 3D wood textures and patterns, comprising the following steps:

[0008] Step 1: Select wood with appropriate reflectivity;

[0009] Step 2: Saw the wood into boards with the required thickness;

[0010] Step 3: Use a carving machine to carve the patterns to be presented on the board;

[0011] Step 4: Soften the wood by increasing the wood temperature;

[0012] Step 5: Use a press to flatten the uneven surface of the wood and apply pressure multiple times to release internal stress;

[0013] Step 6: Polish the wood to obtain the required 3D stereoscopic effect.

[0014] As a further optimized solution of the present invention, in Step 1, the wood with appropriate reflectivity includes nanmu, gold camphor, Brazilian flower, and Burmese rosewood.

[0015] As a further optimized solution of the present invention, in step two, the overall thickness includes the finished product thickness plus the pattern thickness plus the compression loss.

[0016] As a further optimized solution of the present invention, in step four, the heat-conducting oil heating method is adopted, and the pressure is applied after the heating temperature reaches 110 - 160 °C.

[0017] As a further optimized solution of the present invention, in step four, before heating and softening the wood, the moisture content of the wood should be 6 - 12%.

[0018] As a further optimized solution of the present invention, in step five, when flattening, press down 1 mm every 2 minutes.

[0019] As a further optimized solution of the present invention, in step six, before polishing the wood, the wood temperature should be lowered to below 40 °C.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] The present invention engraves concave and convex patterns on the wood surface through a carving machine, then softens the wood by heating, and finally flattens the wood using a press to form a 3D three-dimensional texture. By changing the texture structure of the wood, it presents a 3D three-dimensional effect, giving the wood a new visual and tactile experience.

[0022] The present invention can be applied to the production of various wood products with 3D three-dimensional texture effects, such as furniture, ornaments, handicrafts, etc., expanding the application fields of wood. Through engraving and flattening techniques, the wood can present more colorful texture effects, such as water wave patterns, phoenix tail patterns, gentian patterns, etc., and patterns such as figures and landscapes can also be engraved, endowing the wood with higher artistic value.

[0029] Next, in conjunction with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0032] A method for making 3D wood texture and pattern, comprising the following steps:

[0033] Step 1: Select wood with appropriate reflectivity. The wood with appropriate reflectivity includes Phoebe zhennan, gold camphor, Brazilian tulipwood, and Burmese rosewood.

[0034] Step 2: Saw the wood into boards with the required thickness. The overall thickness includes the finished product thickness plus the pattern thickness plus the compression loss;

[0035] Step 3: Use a carving machine to carve the pattern to be presented on the board;

[0036] Step 4: Soften the wood by raising the wood temperature. Adopt the heat-conducting oil heating method. After heating the temperature to 130 - 180 °C, start to apply pressure;

[0037] Step 5: Use a press to flatten the uneven surface of the wood. When flattening, press down 1 mm every 2 minutes;

[0038] Step 6: Polish the wood to obtain the required 3D three-dimensional effect. Before polishing the wood, the wood temperature should be lowered to room temperature.

[0039] Specifically, in Step 1, wood selection: The method in the present invention has specific requirements for the selection of wood. Not all woods are suitable for making 3D texture effects. The ideal wood should have appropriate reflectivity to clearly show the texture details. Woods in the black series are not recommended due to their low reflectivity. In addition, hard and brittle woods are prone to breakage during carving and flattening, and are not suitable for the method of the present invention. Recommended woods include Phoebe zhennan, gold camphor, Brazilian tulipwood, and Burmese rosewood, etc. These woods have ideal reflectivity, color, and hardness, and can better present the 3D texture effect.

[0040] Pre-treat the selected wood to ensure that the wood surface is clean, free of dust, oil stains and other impurities. Conduct microwave treatment. First, place the wood in the cavity of the microwave treatment equipment and turn on the equipment for preheating to gradually raise the temperature of the wood to the treatment temperature. For thin wood boards less than 2 cm thick or wood with low moisture content, the preheating time is 1 - 3 minutes; for medium-thick wood boards of 2 - 5 cm, the preheating time is 3 - 5 minutes; for thick wood boards over 5 cm or wood with high moisture content, the preheating time is 5 - 10 minutes.

[0041] After reaching the predetermined temperature, start the microwave treatment. For short-time treatment with mild fiber structure change, the microwave time is 2 - 5 minutes; for medium fiber structure change, the microwave time is 5 - 10 minutes; for deep fiber structure change, the microwave time is 10 - 20 minutes.

[0042] The microwave energy penetrates the wood, causing the water molecules inside the wood to vibrate and generate heat, thereby heating the interior of the wood.

[0043] Through microwave treatment, the lignin and hemicellulose in the wood cell wall are partially pyrolyzed, the cell wall becomes soft, and the wood as a whole becomes more easily processed. The moisture distribution is more uniform, reducing cracking and deformation of the wood during subsequent processing. At the same time, it improves the anti-corrosion and termite resistance of the wood and extends its service life.

[0044] Step Two: Board cutting: Saw the selected wood into boards of the required thickness. The total thickness of the board should include the finished product thickness, the pattern thickness, and the compression loss during the processing.

[0045] Step Three: Engraving patterns: Use a carving machine to engrave the required pattern on the board. The method of the present invention does not limit the pattern design, which can be natural textures such as water ripples, phoenix tail patterns, gentian patterns, raindrop patterns, tiger skin patterns, etc., or patterns such as figures and landscapes.

[0046] Step Four: Softening the wood: Soften the wood by heating to facilitate subsequent flattening operations. The method of the present invention can use the heat transfer oil heating method to heat the wood to an appropriate temperature.

[0047] The softening temperatures of different woods are different. For example, Phoebe zhennan generally starts to be pressurized when heated to 135°C, and Brazilian rosewood needs to be heated to 130 - 150°C to start pressurization. The softening temperature of Phoebe zhennan is 100 - 130°C, and the heating duration is generally 30 - 60 minutes before starting pressurization. Pressurizing too early is likely to cause wood fiber breakage and affect the final effect. The heating time is shown in the following table.

[0048]

[0049] Table 1 Heating time table

[0050] Step Five: Flatten the wood: Place the softened wood in a press and flatten the wood surface by applying pressure to form a 3D three-dimensional texture. Different woods require different pressures. For example, the pressure for Brazilian flower is about 1.5 times that of Phoebe zhennan. The key to the method in the present invention lies in controlling the downward pressure speed to avoid breaking the wood. It is recommended to use a press with a pulsed action to adjust the speed and residence time during the flattening process to ensure that the wood is shaped under slow and uniform pressure. Finally, keep the pressure on the wood until its temperature drops to room temperature to complete the shaping work.

[0051] Step Six: Polish the wood to obtain the desired 3D three-dimensional effect.

[0052] Use a clean soft cloth or polishing wheel, dip an appropriate amount of vegetable polishing agent, and evenly apply it on the wood surface along the grain direction of the wood. Wait for 5 - 15 minutes to allow the polishing agent to slightly penetrate the wood surface. Then use the polishing wheel or soft cloth to polish the wood surface with appropriate pressure and speed to make the polishing agent evenly distributed and form a protective film. The polishing direction should be parallel to the grain direction of the wood.

[0053] After the polishing agent is completely dry, gently wipe the wood surface with a clean soft cloth to remove the excess polishing agent and scum. Check whether there are any omissions or uneven areas on the wood surface and perform supplementary polishing if necessary. Repeat the above polishing steps, applying less polishing agent each time and using a finer polishing wheel or cloth. After the final polishing, use an ultra-fine fiber cloth for the final wipe.
