Technical Field
[0001] This utility model relates to the field of furniture spraying technology, specifically to a metal furniture spraying equipment. Background Technology
[0002] Metal furniture is furniture made primarily of metal tubing, sheet metal, or rods, combined with materials such as wood, various engineered wood panels, glass, and stone. It also includes wrought iron furniture made entirely of metal. Through processing techniques such as stamping, forging, casting, molding, bending, and welding, various shapes can be created. Metal furniture requires a painting process during manufacturing to improve its durability and extend its lifespan.
[0003] Reference patent (Publication No.: CN213194288U; Publication Date: 2021-05-14) discloses a spraying device for metal furniture manufacturing, including a spraying box. A box door is movably connected to the top of the front side of the spraying box, and a positioning block is fixedly connected to the right side of the front side of the box door. A positioning mechanism that cooperates with the positioning block is provided on the front right side of the spraying box. By using a spraying box, box door, positioning block, positioning mechanism, positioning groove, placement rack, adjustment mechanism, paint tank, water pump, inlet pipe, outlet pipe, spraying disc, handle, discharge pipe, control valve, and port in coordination, this invention solves the problem that most existing spraying devices for metal furniture manufacturing are carried out outdoors, causing air pollution, affecting the health of users, and having low safety, thus causing inconvenience to users. This spraying device for metal furniture manufacturing has the advantage of high safety and is worth promoting.
[0004] Based on the aforementioned patent, the material is sprayed onto the furniture through a spraying disc using a water pump. However, the spraying disc is fixed to the inner wall of the spraying box, and its spraying range is relatively fixed. For some complex-shaped or large-sized metal furniture, it may not be possible to achieve uniform spraying in all directions, and spraying dead corners are likely to occur. In addition, the discharge pipe is only located at the bottom left side of the spraying box, and the paint tends to accumulate at the bottom of the box, especially in the corners where it is difficult to completely discharge and is not convenient for drainage. Furthermore, the recovered paint is not filtered and cannot be directly reused. At the same time, the height of the placement rack is fixed, making it difficult to adapt to furniture of different heights. Therefore, this utility model provides a metal furniture spraying device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal furniture spraying device, comprising a spraying box body, wherein the spraying box body is provided with an installation mechanism for spraying metal furniture, the installation mechanism comprising: The collection component includes an inclined surface opened on the bottom surface inside the spray box body. The inclined surface has a V-shaped structure. A discharge port is provided at the center of the inclined surface. A collection shell is provided at the bottom of the discharge port. A filter screen body is provided on the inner wall of the collection shell. The mounting assembly includes a first electric push rod fixed inside the spray box body, a support plate fixed to the upper end of the first electric push rod, a placement plate connected to the upper end of the support plate via a drive assembly, a pressure plate connected to the upper end of the spray box body via a push assembly, a fixing plate fixed to the inner wall of the spray box body, a support shaft connected to the inner wall of the fixing plate via a gear assembly, a connecting block fixed to the outer wall of the support shaft, and a spray head fixed to one end of the connecting block.
[0007] Preferably, the front end of the spray box body is provided with a cabinet door, and the front end of the collection shell is provided with a discharge port that is locked by bolts.
[0008] Preferably, a material box is provided on the outer side wall of the spray box body, and a hose output through the pump body is connected to the upper end of the material box. A through hole for inserting the hose is opened on the side wall of the spray box body, and the other end of the hose is connected to the spray head.
[0009] Preferably, the driving assembly includes a motor body fixed at the center of a support plate, a placement plate located at the output end of the motor body, and drainage holes evenly distributed on the surfaces of the placement plate and the support plate for material outflow. Positioning rods are evenly fixed on the lower end face of the placement plate, and pulleys are rotatably connected to the lower ends of the positioning rods. A circular slide rail is fixed on the upper end face of the support plate, and the pulleys are located inside the circular slide rail.
[0010] Preferably, the push assembly includes a third electric push rod fixed to the upper end of the spray box body, the pressure plate is located at the lower end of the third electric push rod, and a rubber pad is fixed to the surface of the pressure plate.
[0011] Preferably, the gear assembly includes a groove formed in the inner wall of the spray box body, a second electric push rod fixed to the lower end of the groove, a slide rod fixed to the telescopic end of the second electric push rod, the slide rod being slidably connected to the inner wall of the groove, tooth blocks being evenly arranged on one side wall of the slide rod, a support shaft being rotatably connected to the inside of the fixed plate, a transmission gear being fixed to one end of the support shaft, and the transmission gear being meshed with the tooth blocks.
[0012] Beneficial effects This utility model provides a metal furniture spraying device. Compared with the prior art, it has the following advantages: Firstly, when the metal furniture is placed on the placement board, the third electric push rod is activated. The telescopic end of the third electric push rod extends downward, pushing the pressure plate downward to press against the metal furniture and fix it in place. This prevents the metal furniture from moving or shaking during the spraying process, ensuring the accuracy and quality of the spraying. The rubber pad increases the friction between the pressure plate and the metal furniture and also acts as a buffer to prevent damage to the metal furniture. Then, the motor body drives the placement board to rotate, ensuring that the metal furniture is sprayed evenly during the spraying process, improving the spraying quality and efficiency, and ensuring the consistency of the spraying effect. During the rotation, the pulley at the lower end of the positioning rod rolls along the circular slide rail, providing stable support and guidance for the placement board and ensuring its smooth rotation. The drainage holes facilitate the outflow of excess spraying material, preventing material from accumulating on the placement board.
[0013] Secondly, when spraying metal furniture, excess paint will slide down to the bottom of the spray box under gravity. Since the bottom is designed as a V-shaped inclined surface, the paint will flow along the inclined surface towards the discharge port at the center. The V-shaped inclined surface design allows excess paint generated during the spraying process to quickly and effectively collect at the discharge port. Compared with a flat structure, this greatly improves the efficiency of paint collection and reduces paint residue at the bottom of the spray box. The collection shell provides storage space for materials, and the filter body can filter the materials to separate solids from liquids or reusable materials, facilitating the recycling and reuse of materials.
[0014] Thirdly, the first electric push rod of this utility model can flexibly adjust the height of the placement plate to adapt to the placement needs of metal furniture of different sizes. Then, through the extension and retraction movement of the second electric push rod, the up and down movement distance of the slide rod can be precisely controlled, thereby precisely controlling the meshing position of the tooth block and the transmission gear, realizing precise adjustment of the spray head swing angle, expanding the spraying range of the spray head, avoiding spraying dead corners due to the presence of furniture with complex hollows, improving spraying efficiency, and enabling metal furniture to receive spraying more comprehensively and evenly.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-5 This utility model provides a technical solution: a metal furniture spraying device, including a spraying box body 1, on which an installation mechanism for spraying metal furniture is provided, the installation mechanism including: The collection component includes an inclined surface 3 opened on the bottom surface inside the spray box body 1. The inclined surface 3 has a V-shaped structure. A discharge port 301 is provided at the center of the inclined surface 3. A collection shell 302 is provided at the bottom of the discharge port 301. A filter screen body 303 is provided on the inner wall of the collection shell 302. The mounting components include a first electric push rod 4 fixed inside the spray box body 1, a support plate 401 fixed to the upper end of the first electric push rod 4, a placement plate 403 connected to the upper end of the support plate 401 via a drive assembly, a pressure plate 701 connected to the upper end of the spray box body 1 via a push assembly, a fixing plate 604 fixed to the inner wall of the spray box body 1, a support shaft 605 connected to the inner wall of the fixing plate 604 via a gear assembly, a connecting block 606 fixed to the outer wall of the support shaft 605, and a nozzle 502 fixed to one end of the connecting block 606.
[0019] In a preferred embodiment, the front end of the spray box body 1 is provided with a cabinet door 2, and the front end of the collection shell 302 is provided with a discharge port 304 that is locked by bolts. During the metal furniture spraying process, excess spraying material will drip onto the bottom surface inside the spray box body 1. Since the bottom surface is a V-shaped slope 3, the material will converge along the slope 3 towards the discharge port 301 at the center under the action of gravity, and then enter the collection shell 302 through the discharge port 301. After entering the collection shell 302, the material is filtered by the filter screen body 303. Solid impurities are intercepted, while liquid or reusable materials remain in the collection shell 302. When it is necessary to clean the collected material, the discharge port 304 is opened by bolts to take out the material.
[0020] Before spraying, the cabinet door 2 is opened, and the metal furniture is placed on the placement plate 403 inside the spraying box body 1. After placement, the cabinet door 2 is closed to prevent paint from leaking into the external environment during the spraying process, thus protecting the working environment and reducing health hazards to operators.
[0021] In a preferred embodiment, a material box 5 is provided on the outer side wall of the spray box body 1. The upper end of the material box 5 is connected to a hose 501 that is output through the pump body. The side wall of the spray box body 1 is provided with a through hole 503 for inserting the hose 501. The other end of the hose 501 is connected to the nozzle 502. Under the action of the pump body, the material in the material box 5 enters the nozzle 502 through the hose 501 and the through hole 503, and is sprayed out by the nozzle 502 to spray the metal furniture.
[0022] In a preferred embodiment, the driving assembly includes a motor body 402 fixed at the center of a support plate 401, a placement plate 403 located at the output end of the motor body 402, and drainage holes evenly distributed on the surfaces of the placement plate 403 and the support plate 401 for material outflow. A positioning rod 404 is evenly fixed on the lower end face of the placement plate 403, and a pulley 405 is rotatably connected to the lower end of the positioning rod 404. A circular slide rail 406 is fixed on the upper end face of the support plate 401, and the pulley 405 is located inside the circular slide rail 406. When the first electric push rod 4 is activated, the first electric push rod 4 extends or retracts, driving the support plate 401 to rise or fall to a suitable height to facilitate the placement of metal furniture. After the metal furniture is placed on the placement plate 403, the motor body 402 is activated, and the output end of the motor body 402 drives the placement plate 403 to rotate.
[0023] During the rotation of the placement plate 403, the pulley 405 at the lower end of the positioning rod 404, which is uniformly fixed on its lower end face, will roll in the circular slide rail 406 fixed on the upper end face of the support plate 401, which plays a role in stabilizing the rotation of the placement plate 403. At the same time, the drainage holes uniformly opened on the surfaces of the placement plate 403 and the support plate 401 can allow excess paint to pass through, preventing paint from accumulating on the placement plate 403 and the support plate 401.
[0024] In a preferred embodiment, the push assembly includes a third electric push rod 7 fixed to the upper end of the spray box body 1, a pressure plate 701 located at the lower end of the third electric push rod 7, and the pressure plate 701 is rotatably connected to the telescopic end of the third electric push rod 7. A rubber pad 702 is fixed to the surface of the pressure plate 701. When the metal furniture is placed on the placement plate 403, the third electric push rod 7 is activated, and the telescopic end of the third electric push rod 7 extends downward, pushing the pressure plate 701 downward so that the pressure plate 701 presses on the metal furniture and fixes it. Since the pressure plate 701 is rotatably connected to the telescopic end of the third electric push rod 7, when the placement plate 403 drives the metal furniture to rotate, the pressure plate 701 can rotate with it without affecting the rotation of the metal furniture. The rubber pad 702 can increase the friction between the pressure plate 701 and the metal furniture, and at the same time play a buffering role to prevent damage to the metal furniture.
[0025] In a preferred embodiment, the gear assembly includes a groove 6 formed in the inner wall of the spray box body 1. A second electric push rod 601 is fixed to the lower end of the groove 6. A slide rod 602 is fixed to the telescopic end of the second electric push rod 601. The slide rod 602 is slidably connected to the inner wall of the groove 6. Tooth blocks 603 are evenly arranged on one side wall of the slide rod 602. A support shaft 605 is rotatably connected to the inside of the fixed plate 604. A transmission gear 607 is fixed to one end of the support shaft 605. The transmission gear 607 is meshed with the tooth blocks 603.
[0026] Furthermore, the second electric push rod 601 is activated. The telescopic end of the second electric push rod 601 drives the slide rod 602 to slide up and down in the slide groove 6. The toothed block 603 on the side wall of the slide rod 602 meshes with the transmission gear 607. When the slide rod 602 moves up and down, it drives the transmission gear 607 to rotate in both directions, thereby driving the support shaft 605 to rotate in the fixed plate 604. The rotation of the support shaft 605 drives the nozzle 502 to swing through the connecting block 606, thereby adjusting the spraying angle of the nozzle 502.
[0027] Additional notes: The motor model is ECMA-C20604RS, the electric actuator for adjusting the height of the placement plate is DT-50, the electric actuator for controlling the pressing down of the pressure plate and the telescopic slide is XTL100, and the pump body for extracting materials is CB-B6.
[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0029] When performing metal furniture spraying operations, first open the cabinet door 2 on the front side of the spraying box body 1, start the first electric push rod 4 to extend or shorten it to drive the support plate 401 to rise or fall to a suitable height, and place the metal furniture on the placement plate 403. Then, the third electric push rod 7 is activated, and its telescopic end extends downward to push the pressure plate 701 down. The pressure plate 701 is fixed to the metal furniture by the rubber pad 702 on its surface. Since the pressure plate 701 is rotatably connected to the telescopic end of the third electric push rod 7, it does not affect the subsequent rotation of the metal furniture. After the cabinet door 2 is closed, the motor body 402 is activated, and its output end drives the placement plate 403 to rotate. The pulley 405 at the lower end of the positioning rod 404 on the lower end of the placement plate 403 rolls in the circular slide rail 406 on the upper end of the support plate 401 to stabilize the rotation. At the same time, the drainage holes on the surface of the placement plate 403 and the support plate 401 allow excess paint to flow out. Next, the material in the material box 5 is pumped through the hose 501 and the through hole 503 on the side wall of the spray box body 1 to the nozzle 502. The second electric push rod 601 is activated, and its telescopic end drives the slide rod 602 to slide up and down in the slide groove 6. The toothed block 603 on the side wall of the slide rod 602 meshes with the transmission gear 607, driving the transmission gear 607 to rotate forward and backward. This causes the support shaft 605 to rotate in the fixed plate 604. The support shaft 605 drives the nozzle 502 to swing through the connecting block 606 to adjust the spraying angle, so as to achieve full spraying of metal furniture. During the spraying process, excess material drips onto the V-shaped inclined surface 3 on the bottom of the inside of the spray box body 1 and converges towards the central discharge port 301 under the action of gravity. It enters the collection shell 302 through the discharge port 301 and is filtered by the filter screen body 303. Solid impurities are intercepted, and reusable material remains in the collection shell 302. When cleaning is required, the material can be taken out by opening the discharge port 304 with bolts.
