Description

Technical Field

[0001] This invention relates to the field of wood furniture processing technology, specifically to a planing and carving device and method for mahogany furniture. Background Technology

[0002] Rosewood furniture refers to furniture made from classic rosewoods such as sandalwood, fragrant rosewood, striped ebony, black rosewood, red rosewood, chicken wing wood, and padauk. These woods are renowned for their fine texture and high density. Rosewood furniture is characterized by its use of hard, precious woods and meticulous craftsmanship, resulting in high practicality and artistic value. These pieces not only exude a noble and elegant style but also embody profound cultural heritage. The production process of rosewood furniture typically employs traditional techniques such as carving, mortise and tenon joints, inlay, and curved lines. Its appearance is simple and symmetrical, showcasing the natural color and grain of the wood.

[0003] When planing rosewood furniture, the surface grain must be considered, and the planing operation should be carried out at an appropriate angle. At the same time, the deeper grain must also be taken into account; otherwise, planing directly can easily damage the grain and affect the aesthetics. However, in current rosewood furniture processing, it is generally planed directly according to the surface grain, which may cause damage to the grain after planing, reduce the beauty, and even seriously affect the choice of carving patterns, or even make the furniture unusable.

[0004] Therefore, we propose a planing and carving device for rosewood furniture and its planing and carving method. Summary of the Invention

[0005] The purpose of this invention is to provide a planing and carving device and method for rosewood furniture, so as to solve the problem in the above-mentioned background art that the existing rosewood furniture processing does not take into account the deep texture of the board and is prone to producing inferior products.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A planing and carving device for mahogany furniture includes a carving machine, which is equipped with four sets of mounting seats that can move horizontally and vertically. The four sets of mounting seats are respectively equipped with a carving mechanism, a double-head planing mechanism, an ultrasonic testing mechanism, and a board surface scanning mechanism.

[0008] The ultrasonic testing mechanism includes an applicator roller rotatably mounted on a mounting base. An ultrasonic testing probe parallel to the applicator roller is mounted on the bottom of the mounting base. The ultrasonic testing mechanism also includes a coupling agent storage box, a peristaltic pump, and a nozzle. The inlet of the peristaltic pump is installed on one side of the coupling agent storage box and communicates with the inside of the coupling agent storage box. The outlet of the peristaltic pump is connected to the nozzle through a delivery pipe. The nozzle is positioned directly above the applicator roller.

[0009] The dual-head planing mechanism includes a fixed planer blade and an electrically lifting planer blade arranged in parallel. Both the fixed planer blade and the electrically lifting planer blade are mounted on a turntable. The turntable is rotatably mounted on one of the mounting bases via a turntable bearing and is driven by an angle motor.

[0010] Preferably, the turntable has an internal cavity, the top of the turntable is connected to a compressed air supply hose communicating with the internal cavity, and the bottom surface of the turntable has an air jet hole communicating with the internal cavity.

[0011] Preferably, the turntable is provided with a through mounting hole, and the electric lifting planer blade includes an electric hydraulic push rod, which is fixedly installed through the mounting hole.

[0012] Preferably, the electric lifting planer blade plate described above has multiple sliding holes, and a limit rod is slidably installed in the sliding holes. The upper end of the limit rod is fixedly connected to the bottom of the turntable.

[0013] Preferably, the top of the fixed planer blade is connected to the bottom of the turntable by multiple connecting rods, and sufficient chip removal space is left between the fixed planer blade and the turntable.

[0014] Preferably, the ratio of the width of the planer blade of the fixed planer blade to the width of the planer blade of the electric lifting planer blade is 1:0.618.

[0015] Preferably, the horizontal moving seat of the above-mentioned engraving machine is equipped with two sets of vertical moving seats. The two sets of vertical moving seats are driven and controlled separately by two lead screws and lead screw motors, and share a common slide rod. The lead screw nut on the vertical moving seat is threadedly connected to the lead screw, and a linear bearing is connected to the vertical moving seat. The linear bearing is sleeved on the slide rod.

[0016] Preferably, a first laser ranging sensor is connected to the bottom of the aforementioned longitudinally movable base, and a second laser ranging sensor is installed on one side of the mounting base.

[0017] A method for planing and carving rosewood furniture, which uses the aforementioned rosewood furniture planing and carving equipment, includes the following steps:

[0018] S1. Select mahogany boards suitable for planing and carving;

[0019] S2. The surface is initially planed by manual labor or by operating a planer.

[0020] S3. Apply wax to the surface of the pre-processed board.

[0021] S4. Fix the waxed mahogany board onto the processing position of the carving machine;

[0022] S5. Activate the board surface scanning mechanism to scan the surface texture of the mahogany board;

[0023] S6. Start ultrasonic testing to scan the deep texture of the mahogany board;

[0024] S7. Combining the scanning results of S5 and S6, the control center analyzes the texture of the scan results and calls the database to provide multiple matching textures suitable for carving patterns or graphics for people to choose from.

[0025] S8. Manually select and determine the pattern or graphic to be carved. The control center automatically performs a planing process based on the detected board texture and the final carving result, and then carves the graphic automatically. After the carving is completed, it is scanned again and the final graphic is uploaded; the carving is complete.

[0026] As a preferred option, during planing, a fixed planer blade or an electrically operated lifting planer blade can be selected based on the texture. Furthermore, during the planing process, multiple scans can be performed intermittently to verify the planing and achieve more accurate results.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] (1) The ultrasonic testing mechanism set up in this invention can detect the deep texture of the mahogany board before planing, while the board surface scanning mechanism can identify the surface texture of the mahogany board; through the dual detection and analysis of surface texture and deep texture, the error rate of planing is reduced, the aesthetics of mahogany furniture is enhanced, more carving patterns are available, and scrapped products are avoided.

[0029] (2) The double-head planing mechanism can select the appropriate planer width according to the texture to plan different texture widths; and the planer can rotate 360° to adjust the planing along the texture direction without damaging the texture; at the same time, the width of the two planers of the double-head planing mechanism conforms to the golden ratio, and the traces produced after planing or the planing traces left by the person are aesthetically pleasing.

[0030] (3) High-pressure air jet holes are set on the turntable, which can directly blow away wood chips during the planing process; this facilitates the cyclical work of multiple scanning and planing, and improves product quality.

[0031] (4) Before ultrasonic testing, waxing is applied to the surface of the mahogany board to avoid indentations or scratches caused by ultrasonic testing, and to fill the gaps or dents on the surface of the mahogany board, thereby improving the ultrasonic testing results; at the same time, it avoids direct contact between the coupling agent and the surface of the mahogany board, reduces the corrosion of the mahogany board surface by the coupling agent, and improves the quality of the product.

[0032] (5) The control center can be used for overall control, and can intelligently complete scanning, ultrasonic detection, planing and engraving work, which is highly efficient and saves manpower. Attached Figure Description

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] Please see Figure 1-7 A planing and carving device for rosewood furniture includes a carving machine 100. The carving machine 100 is equipped with four sets of horizontally and vertically movable mounting bases 103. The four sets of mounting bases 103 are respectively equipped with a carving mechanism 200, a double-head planing mechanism 300, an ultrasonic testing mechanism 500, and a board surface scanning mechanism 400. The carving mechanism 200 includes carving tools, fixtures, power heads, etc., which are existing technologies. The board surface scanning mechanism 400 uses a line scan camera or an area scan camera. The above equipment is connected to a control center 000, which is equipped with an operation screen, a CPU controller, and other operation and control equipment.

[0048] In practice, the engraving machine 100 has two sets of longitudinal moving seats 102 mounted on its transverse moving seat 101. Each set of longitudinal moving seats 102 is individually driven and controlled by two lead screws 603 and a lead screw motor 601, but shares a common slide rod 602. The lead screw nut 604 on the longitudinal moving seat 102 is threadedly connected to the lead screw 603, and a linear bearing 605 is connected to the longitudinal moving seat 102, which is sleeved on the slide rod 602. The two sets of longitudinal moving seats 102 can be controlled independently without affecting each other. However, it should be noted that a horizontally positioned proximity sensor 900 is installed on one side of one set of longitudinal moving seats 102. This proximity sensor 900 can issue an alarm when the two sets of longitudinal moving seats 102 get too close, preventing collisions between them.

[0049] In implementation, a first laser rangefinder 700 is connected to the bottom of the longitudinal moving base 102, and a second laser rangefinder 800 is installed on one side of the mounting base 103. The first laser rangefinder 700 can detect the thickness of the sheet metal facing downwards, while the second laser rangefinder 800 can detect the thickness of the sheet metal around the planer blade position, thus realizing the measurement of the sheet metal thickness at the processing position.

[0050] Among them, such as Figure 3 As shown, the ultrasonic testing mechanism 500 includes an applicator roller 501 rotatably mounted on a mounting base 103. An ultrasonic testing probe 502 parallel to the applicator roller 501 is mounted on the bottom of the mounting base 103. The ultrasonic testing mechanism 500 also includes a coupling agent storage box 506, a peristaltic pump 507, and a nozzle 503. The coupling agent storage box 506 contains walnut oil, olive oil, or some paste coupling agent that does not harm mahogany. The inlet of the peristaltic pump 507 is installed on one side of the coupling agent storage box 506 and communicates with the interior of the coupling agent storage box 506. The outlet of the peristaltic pump 507 is connected to the nozzle 503 through a delivery pipe 504. The nozzle 503 is located directly above the applicator roller 501. A replenishment port 505 is provided on the mounting base 103, through which coupling agent can be replenished into the coupling agent storage box 506.

[0051] During implementation, it is important to note that a column-type pressure sensor is vertically mounted on one side of the ultrasonic testing probe 502, and the lower end of the pressure sensor is set as an arc surface; during ultrasonic pressure testing, a pressure signal can be generated to avoid excessive pressure on the plate.

[0052] like Figure 4-5 As shown, the double-head planing mechanism 300 includes a fixed planer blade 303 and an electrically lifting planer blade 302 arranged in parallel. Both the fixed planer blade 303 and the electrically lifting planer blade 302 are mounted on a turntable 301. The turntable 301 is rotatably mounted on one of the mounting bases 103 via a turntable bearing 304 and is driven by an angle motor 306. The electrically lifting planer blade 302 has two height fixed positions, upper and lower. When it is in the lower position, the electrically lifting planer blade 302 is downward and lower than the fixed planer blade 303. During operation, only the bottom of the electrically lifting planer blade 302 can contact the mahogany board. When the electrically lifting planer blade 302 is in the higher position, it is completely retracted, and only the fixed planer blade 303 can contact the mahogany board.

[0053] More specifically, such as Figure 5 As shown, the turntable 301 has a through mounting hole 307. The electrically lifting planer blade 302 includes an electro-hydraulic push rod 308, which is fixedly installed through the mounting hole 307. The electrically lifting planer blade 302 has multiple sliding holes 310, within which limit rods 309 are slidably installed. The upper end of the limit rod 309 is fixedly connected to the bottom of the turntable 301. The top of the fixed planer blade 303 is connected to the bottom of the turntable 301 via multiple connecting rods 312, and sufficient chip removal space is provided between the fixed planer blade 303 and the turntable 301.

[0054] Example 2

[0055] Unlike Example 1, in this example, as Figure 5 and Figure 6 As shown, the turntable 301 has an inner cavity 313 inside, and a compressed air supply hose 305 communicating with the inner cavity 313 is connected to the top of the turntable 301. An air jet hole 314 communicating with the inner cavity 313 is opened on the bottom surface of the turntable 301.

[0056] The air jet 314 enables the blowing away of sawdust during processing, cleaning the processing area and keeping it clean for easy processing.

[0057] Example 3

[0058] Unlike Embodiment 1, the width ratio of the planer blade 311 of the fixed planer blade 303 to the width of the planer blade 311 of the electric lifting planer blade 302 is 1:0.618.

[0059] The width ratios mentioned above are the golden ratio, a universally recognized aesthetically pleasing proportion. They allow for the direct creation of smooth, aesthetically pleasing planing marks using a planer, enabling the processing of textures of varying widths while preserving their beauty.

[0060] Example 4

[0061] Unlike Example 1, this example proposes a method for completing planing and carving using the equipment in Example 1, specifically as follows:

[0062] A method for planing and carving rosewood furniture, comprising the following steps:

[0063] S1. Select mahogany boards suitable for planing and carving;

[0064] S2. The surface is initially planed by manual labor or by operating a planer.

[0065] S3. Apply wax to the surface of the pre-processed board.

[0066] S4. Fix the waxed mahogany board onto the processing position of the engraving machine 100;

[0067] S5. Activate the board surface scanning mechanism 400 to scan the surface texture of the mahogany board;

[0068] S6. Start ultrasonic testing to scan the deep texture of the mahogany board;

[0069] S7. Combining the scanning results of S5 and S6, the control center 000 analyzes the texture through the scanning results and calls the database to provide multiple matching textures suitable for carving patterns or graphics for people to choose from.

[0070] S8. Manually select and determine the pattern or graphic to be engraved. The control center 000 automatically performs a planing process based on the detected board texture and the final engraving result, and then engraving is carried out automatically. After completion, a second scan is performed, and the final graphic is uploaded; the engraving is completed.

[0071] During planing, the fixed planer blade 303 and the electrically lifting planer blade 302 can be selected and used according to the texture. During the planing process, the planing can be completed more accurately by intermittently scanning and verifying multiple times.

[0072] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
