Description

Technical Field

[0001] The invention relates to the technical field of high-end equipment, in particular to a polishing machine tool for wooden furniture boards. Background Art

[0002] In the field of furniture board processing, after sanding the wood board, it is usually necessary to polish the sanded wood board, apply wood wax oil, and then polish it again.

[0003] Before applying wood wax oil, the wood board is generally sanded with 240-320 grit sandpaper. The moisture content of the wood board is required to be no more than 20%. First, use polishing cotton or a hair dryer to remove dust and ensure that the surface is clean and dust-free. Then use 180 grit, 320 grit, and 600 grit sandpaper to sand in sequence to ensure a smooth surface. Wet the surface to expand the wood fibers for subsequent sanding. Use 240 grit sandpaper for the final sanding to remove dust.

[0004] After sanding, clean the dust and evenly apply wood wax oil with a brush or spray gun. Apply oil in different areas, making sure each area has enough time to dry. Generally, keep the surface of the board wet for about 5 minutes so that the wood can fully absorb it. Finally, use a polishing machine to polish.

[0005] Generally, after applying the wax oil, you need to wait for a while for the wax oil to dry fully. Usually you need to wait for 12-24 hours; after drying, you can use polishing tools such as polishing cloth to polish. If needed, you can repeat the above polishing steps to ensure that the wax oil is completely penetrated and evenly distributed on the wood surface. Usually you need to apply and polish more than two times to achieve the best effect.

[0006] The disadvantages of the prior art are:

[0007] The polishing area of ​​existing polishing machines is usually small, usually not exceeding 200cm 2 ; Secondly, after applying the wood wax oil, the waiting time is too long, generally 12-24 hours, which is inefficient; and in the prior art, the wood wax oil only relies on slowly penetrating into the wood fibers of the wooden board, and its penetration depth is limited. Taking a walnut board as an example, after two coats of wood wax oil and polishing, the penetration depth of the wood wax oil is generally 0.2-0.5 mm. The penetration depth of the wood wax oil is limited, and even if the wood wax oil is applied several times and then polished, the penetration depth of the wood wax oil will not increase.

[0008] Based on this, the present invention is proposed. Summary of the invention

[0031] The present invention is described in detail below in conjunction with specific embodiments. The embodiments described below are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. Example 1

[0032] like Figure 1 As shown, a wooden furniture board polishing machine includes a roller conveyor for conveying wooden furniture boards 20, the roller conveyor includes a frame 10, a driven roller 11 installed on the frame 10, and an active roller installed on the frame 10, the active roller is driven by a first motor, and also includes a belt polishing mechanism for polishing the wooden furniture board 20, the frame 10 is also equipped with at least one group of high-frequency vibration rollers for applying high-frequency vibration to the wooden furniture board 20, the high-frequency vibration roller group includes two high-frequency vibration rollers 50;

[0033] The resonance frequency of the high-frequency vibration roller 50 is 20-36 MHz.

[0034] In this embodiment, if only polishing operation is performed on the wooden furniture board 20, the wooden furniture board 20 can be polished only by the belt polishing mechanism.

[0035] The active roller rotates, and drives the wooden furniture board 20 thereon to move forward or backward through friction.

[0036] When the wooden furniture board 20 needs to be polished and waxed, the high-frequency vibration roller 50 needs to be started, and the high-frequency vibration generated by the two high-frequency vibration rollers 50 is used to apply high-frequency vibration to the wooden furniture board 20 located on the two high-frequency vibration rollers 50, and then the wooden furniture board 20 can be polished and waxed in conjunction with the belt polishing mechanism; due to the vibration generated by the high-frequency vibration roller 50, the wax layer is easier to disperse during the polishing and waxing operation, the waxing effect is better, and the waxing efficiency is high. In addition, during the wood wax oil polishing operation, due to the drive of the high-frequency vibration roller 50, the wood wax oil is easier to penetrate into the wooden furniture board 20, and the penetration depth of the wood wax oil is deeper, which is conducive to forming better protection for the wooden furniture board 20.

[0037] The present invention adopts a belt polishing mechanism with a larger polishing area to perform large-area polishing operations on the wooden furniture board 20, and can also perform large-area polishing and waxing operations with good polishing and waxing effects; the wooden furniture board 20 can also be polished with wood wax oil, which can significantly increase the penetration depth of the wood wax oil.

[0038] The wooden furniture board polishing machine tool of the present invention has high efficiency, is suitable for wooden furniture boards 20 of different thicknesses, and is highly practical. Example 2

[0039] Based on Example 1, Figure 2 As shown, the belt polishing mechanism includes a main polishing transmission wheel 33, a slave polishing transmission wheel 34, a polishing belt 30, and a second motor 40 for driving the main polishing transmission wheel 33 to rotate. A gear mechanism 41 is arranged between the second motor 40 and the main polishing transmission wheel 33 for transmission. The polishing belt 30 polishes the wooden furniture board 20 through the main polishing transmission wheel 33 and the slave polishing transmission wheel 34. The forward or backward direction of the wooden furniture board 20 is parallel to the axial direction of the main polishing transmission wheel 33, and the axial direction of the main polishing transmission wheel 33 is perpendicular to the axial direction of the high-frequency vibration roller 50.

[0040] The number of the slave polishing transmission wheels 34 can be set as needed. The main polishing transmission wheel 33 is driven to rotate by the second motor 40. The main polishing transmission wheel 33 and the slave polishing transmission wheel 34 cooperate to drive the polishing belt 30 to rotate for polishing. Example 3

[0041] Based on Example 2, in order to facilitate the replacement of the polishing and grinding belt 32 , the polishing belt 30 includes a polymer base belt 31 and a polishing and grinding belt 32 sleeved on the outside of the polymer base belt 31 , and the polishing and grinding belt 32 is connected to the polymer base belt 31 .

[0042] The polishing and grinding belt 32 is a consumable part and needs to be replaced regularly. Example 4

[0043] Based on Example 3, the polymer base belt 31 is embedded with an iron mesh, and the iron mesh is integrally connected to the polymer base belt 31; in the high-frequency vibration roller group, an electromagnetic roller 60 is also arranged between the two high-frequency vibration rollers 50, and the electromagnetic roller 60 includes an iron roller body, and the iron roller body is rotatably connected to the frame 10, and an electromagnet is embedded inside the iron roller body; the electromagnetic roller 60 is located directly below the polishing belt 30.

[0044] Because in the present invention, the polishing area of ​​the polishing belt 32 on the wooden furniture board 20 is very large, for example, it can be 1500cm 2In addition, it is a belt drive. Even if multiple slave polishing drive wheels 34 are provided to ensure the extrusion force, in order to ensure the polishing effect, it is necessary to dynamically adjust the extrusion force of the polishing sanding belt 32 on the wooden furniture board 20.

[0045] The electromagnetic roller 60 generates magnetic force when it is energized, which can generate a magnetic force to attract the iron mesh downward. In this way, the extrusion pressure of the polishing and grinding belt 32 on the wooden furniture board 20 can be dynamically adjusted by adjusting the size of the magnetic force to ensure the polishing effect. Example 5

[0046] Based on Example 4, the axle of the main polishing transmission wheel 33 and the axle of the slave polishing transmission wheel 34 are both installed between the frame 10 by an L-shaped bracket 71, and the axle of the main polishing transmission wheel 33 and the axle of the slave polishing transmission wheel 34 are both rotatably connected to the L-shaped bracket 71, and the L-shaped bracket 71 is connected to the frame 10 by installing a locking screw 72.

[0047] The thickness of commonly used wooden furniture boards 20 can be adjusted, screw holes matching the locking screws 72 are preset on the frame 10, and the locking screws 72 are adjusted to be threadedly connected with the screw holes at different positions, thereby adjusting the distance between the lower part of the polishing belt 30 and the electromagnetic roller 60 / active roller / driven roller 11 to adapt to wooden furniture boards 20 of different thicknesses; and then the magnetic force of the electromagnetic roller 60 is adjusted to ensure the squeezing force of the lower part of the polishing belt 30 on the wooden furniture board 20. Example 6

[0048] Based on Example 1, Figure 3 As shown, the high-frequency vibration roller 50 includes a roller body 51 and a high-frequency vibration rod 53 coaxially connected to the roller body 51. The high-frequency vibration rod 53 is rotatably connected to the frame 10 by installing a bearing. A circular eccentric hole 52 is provided on one side of the roller body 51. The hole wall of the eccentric hole 52 passes through the center of the roller body 51. The high-frequency vibration rod 53 is located in the eccentric hole 52. The intersection of the eccentric hole 52 and the center of the roller body 51 is fully welded to the high-frequency vibration rod 53; the intersection of the eccentric hole 52 and the center of the roller body 51 is located on one side of the eccentric hole 52, and a metal folding plate 55 is sealed between the other side of the eccentric hole 52 and the high-frequency vibration rod 53. The eccentric hole 52 is divided into a non-Newtonian fluid filling chamber 56 and a steel ball filling chamber 54 by the metal folding plate 55 and the high-frequency vibration rod 53. The non-Newtonian fluid filling chamber 56 is filled with a non-Newtonian fluid, and the steel ball filling chamber 54 is filled with steel balls (with a diameter of 2 mm).

[0049] In the present invention, brush connection can be used to simultaneously meet the electrical connection and rotation connection of the lead wire. For example, the lead wires of the high-frequency vibration rod 53 and the electromagnetic roller 60 need to simultaneously meet the electrical connection and rotation connection, and brush connection is used.

[0050] like Figure 5 As shown, in the high-frequency vibration roller group, in the initial state, the direction of the metal folding plate 55 in the first high-frequency vibration roller 50 (upward) is opposite to the direction of the metal folding plate 55 in the second high-frequency vibration roller 50 (downward); when the rotation speeds of the first high-frequency vibration roller 50 and the second high-frequency vibration roller 50 are the same, by reasonably setting the distance between the two, it can be ensured that the direction of the metal folding plate 55 in the first high-frequency vibration roller 50 is always opposite to the direction of the metal folding plate 55 in the second high-frequency vibration roller 50.

[0051] like Figure 4 As shown, the metal folding plate 55 includes a short plate segment 551, a long plate segment 553, and a bending portion 552 located between the short plate segment 551 and the long plate segment 553. The ratio of the length of the short plate segment 551 to the length of the long plate segment 553 is 0.618:1.

[0052] The principle of the high-frequency vibration rod 53 is the same as that of the ultrasonic vibration rod, and piezoelectric ceramics are installed inside. Only the power and transducer parameters of the piezoelectric ceramics are different. The high-frequency vibration rod 53 can generate higher frequency vibrations, and its resonant frequency can reach 20~36MHz.

[0053] Test 1: In this embodiment, during the wood wax oil polishing process, after the wood wax oil is sprayed on the wooden furniture board 20, it is immediately sent and placed between the polishing belt 30 and the roller conveyor without waiting for the wood wax oil to dry, and the electromagnetic roller 60 and the high-frequency vibration roller 50 are started. The resonant frequency of the first high-frequency vibration roller 50 is 22.1MHz, and the resonant frequency of the second high-frequency vibration roller 50 is 22.8MHz, Δx=0.7MHz. Under this condition, polishing assists penetration for 30 minutes to promote the penetration of the wood wax oil. After the polishing is completed, the wooden furniture board 20 is taken out, and after waiting for the wood wax oil to dry, the polishing belt 30 is replaced, and then it is sent between the polishing belt 30 and the roller conveyor for polishing.

[0054] In the process of test 1, when the wooden furniture board 20 is a walnut board, a fir board, and an oak board, the corresponding wood wax oil penetration depth results are shown in Table 1:

[0055] Table 1

[0056] Walnut board Fir board Oak board Wood wax oil penetration depth (mm, test 1) 1.97 2.21 2.02 Wood wax oil penetration depth (mm, existing technology) 0.43 1.55 0.61

[0057] The penetration depth of wood wax oil is measured by metallographic sectioning method through a stereo microscope. The prior art refers to applying wood wax oil twice and polishing without polishing to assist penetration.

[0058] In the present invention, polishing is used to assist penetration when the wood wax oil is not dry, so the penetration depth of the wood wax oil can be significantly increased, especially for wooden boards with dense wood structures, the penetration-promoting effect is significant.

[0059] Test 2: In the high-frequency vibration roller, if the roller body 51 is solid and there is no eccentric hole 52, the corresponding high-frequency vibration roller, due to excessive concentration of vibration energy, can easily cause "white edge" polishing marks to appear on the surface of the wood board after the polishing-assisted penetration is completed. The "white edge" polishing marks are very difficult to remove, and even after multiple subsequent polishings, it is still difficult to completely remove them, affecting the appearance quality.

[0060] Test 3: In the high-frequency vibration roller, if the steel ball filling cavity 54 is not filled with steel balls, but is also filled with non-Newtonian fluid, the non-Newtonian fluid of the present invention is made by mixing starch and water in a mass ratio of 3:1. This high-frequency vibration roller is used to assist in polishing and assisting penetration. When the continuous polishing and assisting penetration area exceeds 2.7m 2 When polishing, a "white edge" polishing mark will definitely appear on the edge of the wooden furniture board 20.

[0061] Similarly, in the high-frequency vibration roller, if the non-Newtonian fluid filling chamber 56 is filled with steel balls, since the non-Newtonian fluid filling chamber 56 and the steel ball filling chamber 54 are essentially two symmetrical structures, due to the offsetting effect of the action force and the reaction force, poor polishing is likely to occur during the continuous polishing assisted penetration process.

[0062] Based on the same principle, in the high-frequency vibration roller, if the ratio of the length of the short plate section 551 to the length of the long plate section 553 is 1:1, then when the high-frequency vibration roller is used to assist in polishing and assisted penetration, the continuous polishing and assisted penetration area exceeds 3.7m 2 When polishing, a "white edge" polishing mark will definitely appear on the edge of the wooden furniture board 20.

[0063] If the high-frequency vibration rod 53 is replaced by an ultrasonic vibration rod, the corresponding frequency varies between 20 and 50 kHz, and the frequency difference between the two ultrasonic vibration rods is 2 kHz. It is found that no matter how the ultrasonic frequency is adjusted, a large number of fish scale polishing marks will inevitably appear on the surface of the wooden furniture board 20 after the polishing-assisted penetration is completed.

[0064] Test 4: In the high-frequency vibration roller, if the eccentric hole 52 is replaced by a concentric hole (forming a concentric circle structure with the roller body 51), such as Figure 6 As shown, when the high-frequency vibration roller is used to assist in polishing-assisted penetration, a large number of fish-scale polishing marks will inevitably appear on the surface of the wooden furniture board 20 after the polishing-assisted penetration is completed.

[0065] Test 5: In the high-frequency vibration roller group, if the direction of the metal folding plate 55 in the first high-frequency vibration roller 50 is always the same as the direction of the metal folding plate 55 in the second high-frequency vibration roller 50, then due to the offset effect of the symmetrically arranged action force and reaction force, the continuous polishing auxiliary penetration area exceeds 0.7m2 When polishing, a large area of ​​"white edge" polishing marks will appear on the edge of the wooden furniture board 20.

[0066] Test 6: For a walnut board (the wooden furniture board 20 is a walnut board), if the resonance frequencies of the two high-frequency vibration rollers 50 are both less than 20 MHz, the corresponding method in reference test 1 is used, and the results of the penetration depth of the wood wax oil are shown in Table 2:

[0067] Table 2

[0068] Wood wax oil penetration depth (mm) Resonance frequency of the first high-frequency vibration roller (MHz) Resonance frequency of the second high-frequency vibration roller (MHz) 0.51 1 1.7 0.72 5 5.7 0.85 10 10.7 0.63 15 15.7 0.67 19 18.3

[0069] Test 7: In this test, the wooden furniture board 20 is a walnut board, the resonance frequency of the first high-frequency vibration roller 50 is 22.1MHz, and the resonance frequency of the second high-frequency vibration roller 50 is f. When f changes in the range of 22.1~23.3MHz, the corresponding wood wax oil penetration depth change trend is shown in FIG. Figure 7 ;

[0070] Depend on Figure 7 It can be seen that, preferably, in the high-frequency vibration roller set, the resonance frequencies of the two high-frequency vibration rollers 50 are different, that is, Δx≠0. More preferably, 0.6 MHz≤Δx≤0.8 MHz.

[0071] In addition, it should be understood that those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
