Description

Technical Field

[0001] This utility model relates to the field of fiberboard coating technology, and in particular to a device for uniformly coating fiberboard surface. Background Technology

[0002] Fiberboard, also known as MDF, is a type of engineered wood product made from interwoven lignocellulose fibers using their inherent adhesive properties. Adhesives and / or additives can be applied during manufacturing. Fiberboard is characterized by its uniform texture, small difference in longitudinal and transverse strength, and resistance to cracking. During processing, it is often glued together to bond two or more pieces of fiberboard.

[0003] In the prior art, application number CN202322052856.0 proposes a fiberboard gluing device, which incorporates a limiting component, a gluing component, and a spreading component. The limiting component enables the fiberboard to be positioned during transportation, the gluing component enables uniform gluing on both sides of the fiberboard, and the spreading component enables uniform gluing during the application process. This invention has a simple structure, is easy to operate, and can effectively save manpower and resources, thereby improving work efficiency.

[0004] However, the above-mentioned patent can only be applied to fiberboard of the same thickness because the positions of the sprayer and roller are fixed during use. It cannot apply glue to fiberboard of different thicknesses, resulting in a large limitation of the glue application device. Based on the above problems, this application proposes a fiberboard surface uniform glue application device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a device for uniformly coating fiberboard surfaces, thereby solving the aforementioned problems.

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

[0021] 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.

[0022] Example: Refer to Figure 1-5A device for uniformly applying adhesive to the surface of fiberboard includes a mounting base 1, a mounting frame 2 fixedly mounted on the top of the mounting base 1, a lifting assembly mounted on the surface of the mounting frame 2, a lifting plate 13 mounted inside the mounting frame 2 via the lifting assembly, a circular guide post 31 fixedly mounted on the top of the lifting plate 13 and slidably mounted inside the mounting frame 2, a fixing plate 14 fixedly mounted inside the mounting frame 2, fixing seats 15 fixedly mounted on the top of the fixing plate 14 and the bottom of the lifting plate 13, a conveying pipe 16 fixedly mounted inside the fixing seat 15, a nozzle 17 fixedly mounted at the discharge end of the conveying pipe 16, and positioning components mounted inside both the lifting plate 13 and the fixing plate 14. A mounting frame 24 is fixedly installed on the left side of the mounting bracket 2. A smoothing component is installed inside the mounting frame 24. The lifting component includes a mounting housing 3 fixedly installed on the rear side of the mounting bracket 2. A servo motor 4 is fixedly installed on the left side of the mounting housing 3. A coupling is fixedly installed at the output end of the servo motor 4. A worm gear 5 is mounted on the output end of the servo motor 4 via the coupling. The worm gear 5 is rotatably located inside the mounting housing 3. A worm wheel 6 is meshed on the surface of the worm gear 5. Both the worm gear 5 and the worm wheel 6 are made of metal and are located inside the mounting housing 3. The mounting housing 3 is made of metal. A rotating rod 7 is fixedly installed inside the worm wheel 6. The rotating rod 7 is rotatably located inside the mounting housing 3. Inside the frame 2, a rotating plate 8 is fixedly mounted on the surface of the rotating rod 7. A connecting shaft 9 is rotatably mounted inside the rotating plate 8. A push plate 10 is rotatably mounted on the surface of the connecting shaft 9. A mounting shaft 11 is rotatably mounted inside the push plate 10. A mounting seat 12 is fixedly mounted at the end of the mounting shaft 11. A lifting plate 13 is fixedly mounted on the bottom of the mounting seat 12. A servo motor 4 drives a coupling to rotate a worm gear 5. The worm gear 5, through a meshing worm wheel 6, drives the rotating rod 7 to rotate inside the mounting frame 2. This causes the rotating rod 7 to rotate the rotating plate 8 counterclockwise. The rotating plate 8, through the connecting shaft 9, drives the push plate 10 to move, causing the mounting shaft 11 to move the mounting seat 12 downwards. Mounting base 12 drives lifting plate 13 to move downward, and circular guide post 31 limits and guides the moving lifting plate 13, so that lifting plate 13 drives conveying pipe 16 to move downward through fixed base 15, so that conveying pipe 16 drives nozzle 17 to move downward, and positioning component limits the position of nozzle 17, so that nozzle 17 and fiberboard maintain a fixed distance. Moreover, the distance between nozzle 17 and fiberboard can be adjusted by positioning component, so as to avoid the distance between nozzle 17 and fiberboard being too close or too far. In addition, the distance between nozzle 17 and fiberboard can be adjusted according to the needs of fiberboard coating, so that glue can be applied to fiberboard of different thicknesses.

[0023] Specifically, the positioning component includes four adjusting rods 18, which are slidably disposed inside the lifting plate 13 and the fixed plate 14, respectively. A mounting plate 19 is fixedly disposed at the end of each adjusting rod 18. Several ball bearings 20 are overlapped inside the mounting plate 19 and are symmetrically distributed. The ball bearings 20 are made of metal. A limiting plate 21 is fixedly disposed on the side of the mounting plate 19 away from the adjusting rods 18, and the limiting plate 21 overlaps with the ball bearings 20. A measuring rod 23 is fixedly disposed on the side of the mounting plate 19 near the adjusting rods 18. An adjusting nut 22 is threaded onto the surface of the adjusting rods 18. Depending on the fiberboard adhesive application requirements, rotating the adjusting nut 22 pulls the adjusting rods 18, thereby driving the mounting plate 18. The mounting plate 19 moves, and the mounting plate 19 drives the ball bearing 20 to move through the limiting plate 21, thereby adjusting the position of the ball bearing 20. This adjusts the distance between the nozzle 17 and the fiberboard. After the upper and lower ball bearings 20 come into contact, the reading of the measuring rod 23 outside the lifting plate 13 and the fixed plate 14 is zero. Therefore, the scale of the measuring rod 23 outside the lifting plate 13 and the fixed plate 14 is the distance the ball bearing 20 has moved. After adjustment, the distance between the nozzle 17 and the fiberboard can be fixed, avoiding the situation where the distance between the nozzle 17 and the fiberboard is too far, resulting in a large amount of glue mist not adhering to the board and directly drifting into the air, causing glue waste. It also avoids the situation where the glue sprayed from the spray head has a large impact force, which may damage the texture structure of the fiberboard surface or cause the pre-coated coating to wrinkle.

[0024] Specifically, the smoothing assembly includes a hydraulic push rod 25 fixedly mounted on the surface of the mounting frame 24. A movable frame 26 is fixedly mounted at the output end of the hydraulic push rod 25. A fixed bracket 27 is fixedly mounted at the rear of the movable frame 26. A drive motor 28 is fixedly mounted at the rear of the fixed bracket 27. A coupling is fixedly mounted at the output end of the drive motor 28. Two smoothing rollers 29 are mounted at the output end of the drive motor 28 via the coupling. The two smoothing rollers 29 are symmetrically distributed and rotatably mounted inside the movable frame 26. A measuring rod 30 is fixedly mounted on the surface of the movable frame 26 and slidably mounted inside the mounting frame 24. The finished fiberboard is then transported... The material is fed into the mounting frame 24, and the hydraulic push rod 25 drives the output end to move the moving frame 26 downward. This causes the moving frame 26 to move the measuring rod 30 downward. The measuring rod 30 measures the downward movement distance of the moving frame 26. Since the measuring rod 30 is outside the mounting frame 24 when the upper and lower spreading rollers 29 are in contact, the reading is zero. Therefore, the distance the spreading roller 29 has moved can be read from the scale of the measuring rod 30. The position of the spreading roller 29 can be adjusted so that it conforms to the thickness of the adhesive coating on the fiberboard. The mounting base 1 then controls the drive motor 28 through the external controller to drive the coupling to rotate the spreading roller 29, and spreads the adhesive on the fiberboard evenly through the spreading roller 29.

[0025] The fiberboard surface uniform adhesive coating device is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0026] In use: The fiberboard is conveyed into the mounting frame 2 by an external conveying device, so that the fiberboard contacts the ball bearings 20 below. Then, the servo motor 4, controlled by an external controller, drives the coupling to rotate the worm gear 5. The worm gear 5, through the meshing worm wheel 6, drives the rotating rod 7 to rotate inside the mounting frame 2. The rotating rod 7 drives the rotating plate 8 to rotate counterclockwise, so that the rotating plate 8 drives the push plate 10 to move through the connecting shaft 9. The push plate 10 pushes the mounting shaft 11 to move downward, and through the mounting shaft 11, drives the mounting seat 12 to move downward. The mounting seat 12 drives the lifting plate 13 to move downward. Since the lifting plate 13 will drive the circular guide post 31 to slide inside the mounting frame 2, the circular guide post 31 will move the moving lifting plate 13. The lifting plate 13 guides the conveying pipe 16 downward via the fixed seat 15, which in turn moves the nozzle 17 downward. The lifting plate 13 then moves the adjusting rod 18 via the adjusting nut 22, which in turn moves the mounting plate 19. The mounting plate 19 moves the ball bearings 20 downward via the limiting plate 21, so that the upper ball bearings 20 come into contact with the fiberboard. The adhesive is then conveyed to the inside of the conveying pipe 16 via the external conveying equipment, and then enters the inside of the nozzle 17 through the conveying pipe 16 and is sprayed onto the fiberboard. The upper and lower nozzles 17 can spray both sides of the fiberboard simultaneously. The fiberboard with the adhesive sprayed into the mounting frame 24 is then spread evenly by the spreading component.
