Description

Technical Field

[0001] This utility model relates to the field of finger-jointed board production technology, and in particular to an automatic coating box for solid wood finger-jointed boards. Background Technology

[0002] Finger-jointed boards are made of multiple pieces of wood joined together without any additional plywood on top or bottom. Because the vertical wood pieces are joined with a serrated joint, similar to the interlocking of two fingers, they are called finger-jointed boards. Due to their stable structure, high durability, and beautiful appearance, they are widely used in home furnishings, flooring, furniture, doors and windows, and other fields. Coating finger-jointed boards not only enhances their appearance but also provides an extra protective layer, extending the lifespan of the wood and preventing it from deforming, cracking, or corroding due to moisture, sunlight, or mechanical wear.

[0003] Traditional finger-jointed board coating methods usually rely on manual spraying or brushing. This method is not only inefficient, but also makes it difficult to ensure the uniformity and consistency of the coating. At the same time, due to the difference in the amount of paint used and the manual operation, the coating quality fluctuates greatly, affecting the appearance and durability of the final product. After coating, the finger-jointed board needs to be dried to cure the paint. However, during the drying process, the paint on the surface of the finger-jointed board is often scratched, which affects the coating effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic coating box for solid wood finger-jointed boards.

[0005] This utility model is achieved using the following technical solution: an automatic coating box for solid wood finger-jointed boards, comprising a coating box body, a support leg fixedly connected to the bottom of the coating box body, a first support frame fixedly connected to the surface of the coating box body, a material conveying mechanism provided on the inner wall of the coating box body, a spraying mechanism provided at the bottom of the coating box body, a second support frame fixedly connected to the surface of the coating box body, a drying mechanism provided on the inner wall of the coating box body, a first through groove opened on the inner wall of the coating box body, a second through groove opened on the inner wall of the coating box body, and a support slider fixedly connected to the inner wall of the coating box body; The material conveying mechanism includes a material conveying motor, an active material conveying roller fixedly connected to the output end of the material conveying motor, an anti-slip layer fixedly connected to the surface of the active material conveying roller, an active gear fixedly connected to the surface of the active material conveying roller, a driven gear meshing with the tooth surface of the active gear, a driven material conveying roller fixedly connected to the inner wall of the driven gear, an auxiliary support roller rotatably connected to the inner wall of the coating box body, a limit groove formed on the surface of the coating box body, a pressure roller slidably connected to the inner wall of the limit groove, spring lifting seats rotatably connected to both ends of the pressure roller, and a limit plate fixedly connected to the surface of the coating box body.

[0006] As a further improvement to the above solution, the surface of the material conveying motor is fixedly connected to the surface of the first support frame, the surface of the driven material conveying roller is fixedly connected with an anti-slip layer, and the surfaces of the active material conveying roller and the driven material conveying roller are rotatably connected to the inner wall of the coating box body.

[0007] The above technical solution involves setting up an active feeding roller and a driven feeding roller. The feeding motor drives the active feeding roller to rotate, while the active gear drives the driven gear to rotate. The active and driven feeding rollers work together to feed the sheet into the device. At the same time, the anti-slip layer ensures friction with the sheet, preventing the sheet from shifting or sliding and ensuring the conveying effect of the device.

[0008] As a further improvement to the above solution, the surface of the spring lifting seat is slidably connected to the inner wall of the limiting plate, and the top of the spring lifting seat is fixedly connected to the surface of the coating box body.

[0009] The above technical solution, by setting a spring lifting seat, lifts the pressure roller when the plate passes through the auxiliary support roller. The spring lifting seat retracts and slides on the inner wall of the limiting plate, and the pressure roller slides on the inner wall of the limiting groove. This ensures that the plate is fixedly clamped while adapting to plates of different thicknesses, thus improving the applicability of the device.

[0010] As a further improvement to the above solution, the spraying mechanism includes a spraying liquid tank, a liquid extraction pipe fixedly connected to the inner wall of the spraying liquid tank, a pump body fixedly connected to the middle of the liquid extraction pipe, an upper spraying pipe fixedly connected to the inner wall of the liquid extraction pipe, a lower spraying pipe fixedly connected to the inner wall of the liquid extraction pipe, and liquid mist nozzles fixedly connected to the inner walls of the upper and lower spraying pipes.

[0011] As a further improvement to the above solution, the top of the spray liquid tank is fixedly connected to the bottom of the coating box body, the surface of the pump body is fixedly connected to the surface of the spray liquid tank, and the surfaces of the upper spray pipe and the lower spray pipe are fixedly connected to the inner wall of the coating box body.

[0012] With the above technical solution, by setting up an upper spray pipe and a lower spray pipe, the board is transported through the first channel to the space between the upper spray pipe and the lower spray pipe. Then, the pump body pumps the paint inside the spray liquid tank to the upper spray pipe and the lower spray pipe through the liquid extraction pipe, and sprays it onto the surface of the board from the liquid mist nozzle. The upper and lower parts are sprayed simultaneously to ensure the uniformity of the coating.

[0013] As a further improvement to the above solution, the drying mechanism includes a discharge motor, the output end of which is fixedly connected to a rotating shaft, a power wheel is fixedly connected to the surface of the rotating shaft, a support wheel is rotatably connected to the surface of the power wheel, a mounting plate is rotatably connected to the surface of the support wheel, an ultraviolet drying lamp is fixedly connected to the inner wall of the coating box body, and a baffle is hinged to the surface of the coating box body.

[0014] As a further improvement to the above solution, the surface of the discharge motor is fixedly connected to the surface of the second support frame, the surface of the rotating shaft is rotatably connected to the inner wall of the coating box body, the surface of the support wheel is rotatably connected to the inner wall of the coating box body, and the surface of the mounting plate is fixedly connected to the surface of the coating box body.

[0015] Through the above technical solution, by setting up ultraviolet drying lamps, the sprayed board passes through the second channel, and then the discharge motor drives the rotating shaft to rotate, so that the power wheel drives the support wheel to transport the board. At the same time, the ultraviolet drying lamp dries the board, and initially fixes the coating on the surface of the board, so as to prevent the coating from being rubbed off during subsequent transportation and ensure the spraying effect of the device.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a material conveying mechanism, specifically an active and a passive conveying roller. A conveying motor drives the active roller to rotate, while a drive gear drives the passive gear. The active and passive rollers work together to feed the sheet material into the device. An anti-slip layer ensures friction with the sheet material, preventing slippage and ensuring efficient conveying. A spring-loaded lifting seat lifts the pressure roller as the sheet material passes the auxiliary support roller. The spring-loaded lifting seat retracts and slides against the inner wall of the limiting plate, while the pressure roller slides along the inner wall of the limiting groove. This ensures the sheet material is securely clamped while accommodating sheets of varying thicknesses, improving the device's applicability.

[0017] This utility model features a spraying mechanism, specifically an upper spray pipe and a lower spray pipe. The sheet material is transported through a first channel to the space between the upper and lower spray pipes. Then, a pump body draws the coating liquid from the spray liquid tank into the upper and lower spray pipes through a liquid extraction pipe, and sprays it onto the surface of the sheet material from the liquid mist nozzle. The simultaneous spraying from both the upper and lower parts ensures uniform coating.

[0018] This invention features a drying mechanism, specifically an ultraviolet drying lamp. The coated board passes through a second channel, and then a discharge motor drives a rotating shaft to rotate, causing a power wheel to drive a support wheel to transport the board. Simultaneously, the ultraviolet drying lamp dries the board, initially fixing the coating onto the board surface. This prevents the coating from being rubbed off during subsequent transportation, ensuring the coating effect of the device. Attached Figure Description

[0029] The implementation principle of an automatic coating box for solid wood finger-jointed boards in this embodiment is as follows: During use, the board is placed between the active feeding roller 402 and the driven feeding roller 406. The feeding motor 401 is started to drive the active feeding roller 402 to rotate. Simultaneously, the active gear 404 drives the driven gear 405 to rotate. The active feeding roller 402 and the driven feeding roller 406 cooperate to feed the board into the device. At the same time, the anti-slip layer 403 ensures friction with the board, preventing the board from shifting or sliding. When the board passes through the auxiliary support roller 407, it lifts the pressure roller 409. The spring lifting seat 410 retracts and slides on the inner wall of the limiting plate 411. The pressure roller 409 slides on the inner wall of the limiting groove 408, ensuring the board is firmly clamped while accommodating boards of different thicknesses. Then, the board passes through the first through groove 8. The coating is conveyed between the upper spray pipe 504 and the lower spray pipe 505. Then, the pump body 503 draws the coating from the inside of the spray liquid tank 501 to the upper spray pipe 504 and the lower spray pipe 505 through the liquid extraction pipe 502. The coating is then sprayed onto the surface of the board through the liquid mist nozzle 506, with simultaneous spraying from both top and bottom. The coated board passes through the second through groove 9, and then the discharge motor 701 drives the rotating shaft 702 to rotate, causing the power wheel 703 to drive the support wheel 704 to transport the board. At the same time, the ultraviolet drying lamp 706 dries the board, initially fixing the coating on the surface of the board to prevent the coating from being rubbed off during subsequent transportation. After the coating on the surface of the board is dry, the support wheel 704 continues to transport the board, and the baffle 707 is opened to discharge the dried board.
