[0016] A water-based paint treatment process for wooden furniture production, the specific steps of which are as follows:
[0017] Step 1: Check the surface color of the product and bleach it to make the surface color uniform;
[0018] Step 2: Use a sander (180 grit sandpaper) to sand through and smooth the flat areas, and then sand other parts such as the flower holes, base plate, and flower board until they are smooth and thoroughly sanded, removing more than 50% of the rough edges;
[0019] Step 3: Apply water-based primer to each part, ensuring that there is no primer buildup at the base of the flowers or along the lines;
[0020] Step 4: After the water-based primer has dried completely, use a sander (180 grit sandpaper) to sand and smooth the flat areas. Use a sander ball or hand sander to smooth and sand through all the areas such as the holes, base, and panels.
[0021] Step 5: Spray a coat of water-based primer onto the product until about 70% of the pores are blocked, making sure to spray the bottom, corners, and pores thoroughly.
[0022] Step 6: After the water-based primer is completely dry, use a sander (214 grit sandpaper) to sand and smooth the flat areas. All areas such as the flower holes, flower base, flower board and other parts should be sanded smooth by hand or with a sanding ball. After sanding with 214 grit sandpaper, use 320 grit sandpaper to sand all the way through. There should be no obvious sanding marks on the panel.
[0023] Step 7: Apply the color evenly according to the shades of the wood, ensuring no obvious joints. The color should also be applied into the holes and crevices. After applying the color, check for evenness and any areas that are too dark. Pay attention to any gaps in the white areas, corners, and crevices. Also, paint the white areas.
[0024] Step 8: The topcoat should be sprayed thoroughly, and the white areas should be sprayed several times to ensure there are no runs, bubbles, whitening, or wrinkles.
[0025] Step 9: After the topcoat is completely dry, sand the surface thoroughly with 400 grit sandpaper. The surface should be flat, without particles or sanding marks. Sand the decorative panels and other parts thoroughly with old 400 grit sandpaper first, then sand with a 400 grit sandpaper ball. Finally, sand the product with fine dry sandpaper to achieve a glossy finish. Do not sand the lines, decorative panels, or edges white.
[0026] Step 10: Use a water-based paint treatment device in the production of wooden furniture to remove dust from the product surface. Spray water-based lacquer onto the product. Waxing can only be done after the water-based lacquer is completely dry. Wax the entire set of products, making sure to apply wax to every part. Finally, use clean cotton yarn to wipe all the wax off the bottom, decorative panels, flat surfaces, and perforations, leaving no area untouched.
[0027] Compared with the prior art, the present invention has the following advantages:
[0028] The present invention provides a water-based paint treatment device for wooden furniture production. The felt pile removes dust from the surface of the table legs, while the elastic rope sinks into the recesses of the table legs during movement. The felt pile on the elastic rope also removes dust from the recesses and carries away any impurities stuck in the recesses, thus preventing dust residue from remaining on the table legs and affecting the subsequent water-based paint spraying quality.
[0029] The present invention provides a water-based paint treatment device for wooden furniture production. After the dust on the surface of the table legs is cleaned, the elastic rope is no longer restricted by the table legs and vibrates under the action of its own material. The vibration shakes the dust attached to the felt into the collection box, achieving the effect of automatically removing dust from the felt and eliminating the need for manual cleaning.
[0030] The water-based paint treatment device for wooden furniture production obtained by the present invention restricts the sliding column by means of an inclined chute when spraying water-based paint on the table legs. This allows the sliding column to move along the trajectory of the inclined chute, so that the sliding column carrying the spray head always maintains a certain distance from the outer surface of the table leg. This adapts to the shape of the table leg to spray water-based paint, thereby ensuring uniform spraying of water-based paint and avoiding the problem of uneven paint thickness caused by repainting.
[0031] The present invention provides a water-based paint treatment device for wooden furniture production. When the spray nozzle is spraying the four sides of the rectangular block of the table leg, the baffle is moved to stop blocking the nozzle outlet, thereby increasing the spraying range of the nozzle and making the nozzle outlet horizontal with the upper surface of the rectangular block of the table leg. Then the nozzle sequentially sprays the four sides of the rectangular block of the table leg.
[0032] The water-based paint treatment device for wooden furniture production obtained by the present invention, as described above, allows some water-based paint to drift in all directions during the spraying process. The drifting water-based paint is intercepted by a folded canvas to prevent it from adhering to the equipment and causing pollution. Furthermore, the sponge material on the inside of the folded canvas absorbs all the water-based paint, preventing it from forming droplets and continuing to fall and pollute the equipment.
[0033] The present invention provides a water-based paint treatment device for wooden furniture production. A screen intercepts fragments of the water-based paint, preventing them from entering the delivery pipe or nozzle and causing blockages. A scraper then removes the fragments from the outside of the screen and pushes them away from the screen to prevent them from accumulating and clogging the openings. Finally, a needle plate with a cone-shaped pin clears any blockages in the screen openings, preventing broken fragments from getting stuck and affecting the flow rate of the water-based paint.

[0056] The lifting assembly includes a mounting bracket 101, a first electric push rod 102, and a receiving plate 103; the mounting bracket 101 is fixedly connected to the middle of the upper surface of the base frame 1; a first electric push rod 102 is bolted to the left and right sides of the mounting bracket 101; the telescopic parts of the two first electric push rods 102 are jointly fixed to the receiving plate 103; an arc-shaped groove 103a is provided on the left side of the receiving plate 103, and the arc-shaped groove 103a is adapted to the lower cylinder of the table leg 8; a rectangular groove 103b is provided on the right side of the receiving plate 103, and the rectangular groove 103b is adapted to the upper rectangular block of the table leg 8.
[0057] The clamping assembly includes a U-shaped plate 201, a second electric push rod 202, a connecting seat 203, a first motor 204, a pressure block 205, and a pressure column 206. A U-shaped plate 201 is fixedly connected to the left and right sides of the support frame 2. A second electric push rod 202 is bolted to each U-shaped plate 201. The telescopic part of the right-side second electric push rod 202 is fixedly connected to the connecting seat 203. The first motor 204 is bolted to the connecting seat 203. The output shaft of the first motor 204 is fixedly connected to the pressure block 205. Three first pins 205a arranged in a circular array are provided on the left side of the pressure block 205. The telescopic part of the left-side second electric push rod 202 is fixedly connected to the pressure column 206. A second pin 206a is provided on the right side of the pressure column 206.
[0058] The power assembly includes a first electric slide rail 301, a first electric slider 302, a rectangular plate 303, and a third electric push rod 304; the first electric slide rail 301 is bolted to the lower surface of the L-shaped plate 3; the first electric slider 302 is slidably connected to the outer surface of the first electric slide rail 301; the rectangular plate 303 is fixedly connected to the lower surface of the first electric slider 302; the third electric push rod 304 is bolted to the lower surface of the rectangular plate 303; the telescopic part of the third electric push rod 304 is fixedly connected to the arc-shaped plate 4.
[0059] The rotations described below refer to rotations from front to back, top to bottom, and right to left. In use, the water-based paint treatment device for wooden furniture production is first placed in the desired position. Because the outer surface of the table leg 8 is covered with a large amount of dust, and impurities are trapped in the recesses 8b of the table leg 8, existing technology uses an air gun to blow away the dust from the surface of the table leg 8. However, the impurities trapped in the recesses 8b cannot be completely blown away. Furthermore, the dust blown into the air by the air gun is easily inhaled, posing a health hazard. Therefore, the operator places the processed table leg 8 horizontally on the support plate 103, with one cylindrical end of the table leg 8 located within the arc-shaped groove 103a. The rectangular block of the table leg 8... One end is located in the rectangular groove 103b. Then, the two first electric push rods 102 are controlled to push out, driving the receiving plate 103 and the table leg 8 to move upward, moving the table leg 8 between the pressure block 205 and the pressure column 206. Then, the two second electric push rods 202 are controlled to push out, driving the pressure block 205, the pressure column 206 and the connected parts to move towards each other, so that the three first pins 205a of the pressure block 205 are inserted into the three pin holes 8a on the right side of the table leg 8, and the second pin 206a of the pressure column 206 is inserted into one pin hole 8a on the left side of the table leg 8, so that the table leg 8 is clamped by the pressure block 205 and the pressure column 206. Then, the two first electric push rods 102 are controlled to drive the connected parts to reset.
[0060] Once the table leg 8 is clamped, the first electric slider 302 is controlled to move to the left on the outer surface of the first electric slide rail 301. The first electric slider 302 drives the rectangular plate 303, the third electric push rod 304, the curved plate 4, the felt 5, the elastic rope 6, and the collection box 7 to move together, moving the felt 5 behind the rectangular block of the table leg 8. Then, the third electric push rod 304 is controlled to push out, driving the curved plate 4, the felt 5, the elastic rope 6, and the collection box 7 forward, causing the felt 5 and the elastic rope 6 to be deformed by the table leg 8. Completely conforming to the shape of table leg 8, the output shaft of the first motor 204 is controlled to rotate counterclockwise, causing the pressure block 205 and table leg 8 to rotate counterclockwise together around the second pin 206a of the pressure column 206. This causes the dust on the rectangular block surface of the table leg 8 to be brushed off by the felt 5 and fall into the collection box 7. At this time, the first electric slider 302 is controlled to drive the connected parts to continue to move to the left, so that the felt 5 conforms to the shape of the table leg 8 and moves to the left, brushing off the dust on the surface of the table leg 8 from left to right.
[0061] When the felt 5 brushes away the dust from the rectangular blocks of the table leg 8 and moves to the recess 8b of the table leg 8, the felt 5, due to its material properties, cannot completely sink into the recess 8b to remove the dust. At this point, the elastic cord 6 on the felt 5, under tension, will automatically detach from the felt 5, conform to the shape of the table leg 8, and sink into the recess 8b. The felt cord 6 will then brush away the dust from the recess 8b downwards. After the felt 5 passes the recess 8b and continues to move to the left, the felt 5 and the elastic cord 6 will be on the same plane. The elastic cord 6 will then return to the felt 5, continuing to brush away the dust in the middle of the table leg 8. Under the action of the felt cord 5, the dust in the spiral groove 8c in the middle of the table leg 8 is also brushed away until the felt 5... After moving to the leftmost end of the table leg 8, control the first electric slider 302 to stop moving. At this time, the dust on the surface of the table leg 8 has been cleaned and collected in the collection box 7, thus preventing the dust from being blown into the air by the air gun and being inhaled by the user, which would harm their health. Then, control the third electric push rod 304 to retract, driving the connected parts to reset. After the felt 5 is no longer squeezed by the table leg 8, it will automatically recover. However, after the elastic rope 6 is no longer restricted by the table leg 8, it will vibrate under the action of its own material. The vibration of the elastic rope 6 will shake the dust attached to the felt 5 into the collection box 7, achieving the effect of automatically removing the dust from the felt 5, saving the step of manual cleaning. After the elastic rope 6 stops vibrating, control the first electric slider 302 to drive the connected parts to reset.

[0064] It also includes an irregularly shaped plate 410, a folded canvas 411, and an irregularly shaped ring 412; the irregularly shaped plate 410 is fixed to the right side of the left U-shaped plate 201; the folded canvas 411 is fixed to the right side of the irregularly shaped plate 410, and the folded canvas 411 has the same shape as the irregularly shaped ring 412; the irregularly shaped ring 412 is fixed to the right end of the folded canvas 411; the irregularly shaped ring 412 is fixed to the connecting block 407.
[0065] The inner side of the folded canvas 411 is made of sponge material, which absorbs the water-based paint sprayed on the inner side of the folded canvas 411 of the irregular ring 412, preventing the water-based paint from falling onto the equipment and causing pollution.
[0066] After the dust on the surface of the table legs 8 is cleaned, due to the varying shapes of the table legs 8, manual painting cannot guarantee a uniform paint layer thickness. Furthermore, existing equipment cannot accommodate the shapes of the table legs 8. Therefore, the operator first opens the cover 402, adds water-based paint to the storage box 401, and then controls the second electric slider 406 to move to the right on the outer surface of the second electric slide rail 405. The second electric slider 406 drives the connecting block 407, the sliding column 408, the spray nozzle 409, the right end of the folded canvas 411, and the irregular ring 4. 12. The fourth electric push rod 413 and the baffle 414 move to the right together, unfolding the folded canvas 411. The slide column 408 slides to the right in the inclined slide groove 3a. When the nozzle 409 moves above the table leg 8, the nozzle 409 is opened, so that the water-based paint in the storage box 401 is transported to the nozzle 409 through the barrel 403 and the delivery pipe 404. Then, the water-based paint is sprayed onto the table leg 8 through the notch 414a. At this time, the table leg 8 is continuously rotating, so that the water-based paint sprayed by the nozzle 409 will evenly cover the surface of the table leg 8.
[0067] However, as the slide column 408 moves continuously within the inclined slide groove 3a, it will follow the trajectory of the inclined slide groove 3a, carrying the spray head 409 upward within the vertical slide groove 407a. Because the trajectory of the inclined slide groove 3a is adapted to the shape of the table leg 8, the spray head 409 moves along the trajectory of the inclined slide groove 3a, maintaining a certain distance from the outer surface of the table leg 8. This adapts to the shape of the table leg 8 to spray water-based paint, thereby ensuring uniform spraying of the water-based paint and avoiding repainting, which would result in uneven paint thickness.
[0068] When the spray nozzle 409 finishes spraying the recessed area 8b of the table leg 8, the second electric slider 406 is stopped, the spray nozzle 409 is turned off, and the output shaft of the first motor 204 is rotated to the initial state. Then, the fourth electric push rod 413 is pushed out, driving the baffle 414 to move, no longer blocking the nozzle 409's outlet, increasing the spraying range of the spray nozzle 409, making the nozzle 409's outlet equal to the width of the upper surface of the rectangular block of the table leg 8. The second electric slider 406 is then controlled to continue moving the spray nozzle 409 to the right, while the spray nozzle 409 is turned on during the movement, spraying water-based paint onto the upper surface of the rectangular block of the table leg 8. After the upper surface of the rectangular block of table leg 8 is sprayed, control the spray nozzle 409 to stop spraying, and the second electric slider 406 to stop moving. Then, control the output shaft of the first motor 204 to rotate the table leg 8 ninety degrees, so that the other side of the rectangular block of table leg 8 faces upward. Then control the second electric slider 406 to drive the connected parts to move to the left, and the spray nozzle 409 automatically turns on. They work together to spray water-based paint on the upward-facing side of the rectangular block of table leg 8. The remaining two sides of the rectangular block of table leg 8 are then sprayed in the same way. After the water-based paint on the surface of table leg 8 is completed, control all parts to reset. During the spraying process, some water-based paint will drift in all directions using the spray nozzle 409. At this time, the folded canvas 411 intercepts the drifting water-based paint and adheres it to the inside of the folded canvas 411 to prevent it from adhering to the equipment and causing contamination. However, if too much water-based paint adheres to the inside of the folded canvas 411, it will form droplets and fall from both ends of the folded canvas 411. The sponge on the inside of the folded canvas 411 absorbs all the water-based paint, preventing the water-based paint from forming droplets and continuing to fall down, thus preventing contamination of the equipment.

[0073] A water-based paint treatment process for wooden furniture production, the specific steps of which are as follows:
[0074] Step 1: Check the surface color of the product and bleach it to make the surface color uniform;
[0075] Step 2: Use a sander (180 grit sandpaper) to sand through and smooth the flat areas, and then sand other parts such as the flower holes, base plate, and flower board until they are smooth and thoroughly sanded, removing more than 50% of the rough edges;
[0076] Step 3: Apply water-based primer to each part, ensuring that there is no primer buildup at the base of the flowers or along the lines;
[0077] Step 4: After the water-based primer has dried completely, use a sander (180 grit sandpaper) to sand and smooth the flat areas. Use a sander ball or hand sander to smooth and sand through all the areas such as the holes, base, and panels.
[0078] Step 5: Spray a coat of water-based primer onto the product until about 70% of the pores are blocked, making sure to spray the bottom, corners, and pores thoroughly.
[0079] Step 6: After the water-based primer is completely dry, use a sander (214 grit sandpaper) to sand and smooth the flat areas. All areas such as the flower holes, flower base, flower board and other parts should be sanded smooth by hand or with a sanding ball. After sanding with 214 grit sandpaper, use 320 grit sandpaper to sand all the way through. There should be no obvious sanding marks on the panel.
[0080] Step 7: Apply the color evenly according to the shades of the wood, ensuring no obvious joints. The color should also be applied into the holes and crevices. After applying the color, check for evenness and any areas that are too dark. Pay attention to any gaps in the white areas, corners, and crevices. Also, paint the white areas.
[0081] Step 8: The topcoat should be sprayed thoroughly, and the white areas should be sprayed several times to ensure there are no runs, bubbles, whitening, or wrinkles.
[0082] Step 9: After the topcoat is completely dry, sand the surface thoroughly with 400 grit sandpaper. The surface should be flat, without particles or sanding marks. Sand the decorative panels and other parts thoroughly with old 400 grit sandpaper first, then sand with a 400 grit sandpaper ball. Finally, sand the product with fine dry sandpaper to achieve a glossy finish. Do not sand the lines, decorative panels, or edges white.
[0083] Step 10: Use a water-based paint treatment device in the production of wooden furniture to remove dust from the product surface. Spray water-based lacquer onto the product. Waxing can only be done after the water-based lacquer is completely dry. Wax the entire set of products, making sure to apply wax to every part. Finally, use clean cotton yarn to wipe all the wax off the bottom, decorative panels, flat surfaces, and perforations, leaving no area untouched.
[0084] Because water-based paint dries quickly, it is prone to clumping when stored in the storage box 401 for a long time. Clumped water-based paint can easily clog the spray nozzle 409, resulting in uneven spraying and reduced production efficiency. Therefore, the output shaft of the second motor 501 is controlled to rotate clockwise, driving the round shaft 502, stirring blade 503, slip ring 505, scraper 506, column 507 and elastic element 508 to rotate together. The stirring blades 503 stir the water-based paint in the storage box 401, keeping the water-based paint in a flowing state and preventing it from clumping in the storage box 401 and clogging the spray nozzle 409. However, as the water-based paint continues to vibrate in the storage box 401, some of it will splash onto the inner wall of the storage box 401 and flow down from the inner wall. After this part of the water-based paint separates from the whole, it will gradually dry into fragments and fall back into the whole.
[0085] When the nozzle 409 is working, the water-based paint in the storage box 401 is drawn out through the barrel 403 and the delivery pipe 404. When the water-based paint passes through the barrel 403, the fragments in the water-based paint are intercepted by the screen 504 to prevent the fragments from entering the delivery pipe 404 or the nozzle 409 and clogging it. However, the fragments accumulate on the outside of the screen 504, which will also block the holes of the screen 504, causing the flow rate of the water-based paint to decrease, thus affecting the spraying effect of the water-based paint. Therefore, the continuously rotating scraper 506 is used to scrape off the fragments on the outside of the screen 504 and push them away from the screen 504 to prevent the fragments from accumulating on the outside of the screen 504 and clogging the holes.
[0086] Because some fragments break and become lodged in the mesh of the screen 504 due to the squeezing force of the scraper 506 when removing debris from the outside of the screen 504, clogging some of the mesh, it is necessary to periodically control the two fifth electric push rods 509 to extend, causing the cylinder 510, needle plate 511, connecting ring 512, round rod 513, and ring 514 to move to the left. The conical needles on the needle plate 511 then clear the clogged mesh of the screen 504, preventing the broken fragments from getting stuck. Inside the holes, the flow rate of the water-based paint is affected. When the ring 514 moves to the right, it pushes the slip ring 505, scraper 506 and column 507 to move to the right. The elastic element 508 is forced to compress to prevent the continuously rotating scraper 506 from contacting the needle plate 511 that unclogs the holes of the screen 504 and causing interference. After the holes of the screen 504 are unclogged, the fifth electric push rod 509 is controlled to retract, driving the connected components to reset. At the same time, the elastic element 508 drives the slip ring 505, scraper 506 and column 507 to reset.
