Description

Technical Field

[0001] This utility model relates to the field of board processing technology, and in particular to an eco-friendly board gluing device with high uniformity. Background Technology

[0002] Glue application is a crucial process in the manufacturing of eco-friendly engineered wood products. It involves uniformly applying adhesive to the surface of environmentally friendly substrates such as bamboo-wood composite boards, straw boards, and formaldehyde-free fiberboards. This allows multiple layers of veneers or fibers to bond firmly under hot pressing, forming a finished board with excellent mechanical properties and environmental characteristics. The uniformity of the glue application directly affects the bonding strength, weather resistance, formaldehyde release, and the flatness and lifespan of the final product. Especially in the core pretreatment process before veneer assembly, existing glue application equipment is gradually revealing a series of significant limitations and technical problems when dealing with eco-friendly boards of varying densities, thicknesses, and surface characteristics.

[0003] Specifically, existing adhesive coating devices face prominent problems in practical operation, such as uneven adhesive application, poor adaptability, and the tendency to cause localized glue shortages or accumulations. Traditional methods are inconvenient for combing the applied adhesive, resulting in uneven distribution of the adhesive on the board, which in turn affects the coating quality of the eco-friendly boards, making the process extremely inconvenient. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative eco-friendly board adhesive coating device with high uniformity to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an eco-friendly board coating device with high uniformity, which solves the problem in the prior art that it is not easy to comb the coated adhesive, resulting in uneven distribution of adhesive on the board and thus affecting the coating quality of the eco-friendly board.

[0005] To achieve the above objectives, this utility model provides an eco-friendly board gluing device with high uniformity, including a frame, a support plate fixedly connected to the inner side of the frame, and a connecting plate slidably connected to the bottom of the support plate; The top of the support plate is provided with clamps on both sides, and the top of the two clamps is fixedly connected to the top of the connecting plate. A cylinder is fixedly connected to one side of the outer wall of the frame by bolts, and the output shaft of the cylinder passes through the side wall of the frame and is fixedly connected to one side of the connecting plate. A support plate is slidably connected to the upper part of the inner side of the frame, and a spray plate is fixedly connected to the bottom of the support plate. A side frame is fixedly connected to one side of the support plate. A brush roller is rotatably connected to the inner side of the side frame, and a drive motor is fixedly connected to one side of the outer wall of the side frame by bolts. One end of the brush roller passes through the side wall of the side frame and is connected to the output shaft of the drive motor. A pump body is fixedly connected to one side of the outer wall of the frame by bolts, and a support box is fixedly connected to the side of the frame near the pump body. The inlet of the pump body is connected to one side of the support box, and the outlet of the pump body is connected to one side of the spray plate.

[0006] The connecting plate has sliders fixedly connected to both sides of its top, and both sliders are slidably connected to the bearing plate through a groove. One side of each slider is fixedly connected to one side of each clamping plate.

[0007] One side of the frame is fixedly connected to a fixed frame, and the inside of the fixed frame is rotatably connected to a screw rod. One end of the screw rod is connected to a nut seat by thread, and one side of the nut seat is fixedly connected to one side of the support plate.

[0008] One side of the support plate is fixedly connected to a sliding block, and the sliding block is slidably connected to the side wall of the frame through a sliding groove.

[0009] One end of the screw is rotatably connected to the inner wall of the fixed frame via a rotating shaft, and the other end of the screw passes through the side wall of the fixed frame via a bearing sleeve. One end of the brush roller is rotatably connected to the inner wall of the side frame via a rotating shaft, and the other end of the brush roller passes through the side wall of the side frame via a bearing sleeve.

[0010] The pump body has a hose connected to its outlet, and one end of the hose is connected to one side of the spray plate.

[0011] This utility model discloses a highly uniform adhesive coating device for eco-friendly boards. By incorporating a cylinder-driven clamping mechanism within the frame, it solves the problems of uneven adhesive application, poor adaptability, and the tendency for localized glue shortages or accumulation in existing coating devices. A support plate is fixed to the inner side of the frame, providing stable support for the eco-friendly boards and preventing bending or deformation due to its own weight or external forces during the coating process. The cylinder is bolted to the outer wall of the frame, and its output shaft is connected to a connecting plate. This pushes the connecting plate to slide along the bottom of the support plate, causing two clamping plates to clamp and limit the boards on both sides, effectively preventing deformation during spraying and combing. The system prevents lateral movement or vibration, ensuring stability during adhesive application. The clamping plate and connecting plate are fixedly connected at the top, providing a robust structure and uniform clamping force. The pump body is bolted to the outer wall of the frame, with its inlet connected to the carrier box for a stable adhesive supply and its outlet connected to the spray plate, pressurizing and delivering the adhesive to the spray plate. The adhesive is then sprayed through nozzles to form a uniform mist or continuous tape, achieving initial uniform coverage of the board surface. The support plate is slidably connected to the upper inner side of the frame and can move along the length of the board, driving the spray plate to complete a lateral scanning spray, avoiding the localized over- or under-coating problems caused by traditional fixed nozzles, and significantly improving the coating surface. The spray plate is fixed to the bottom of the support plate and moves synchronously with it to ensure a continuous and unobstructed spraying path. The side frame is fixed to one side of the support plate and internally connected to the brush roller. The drive motor is fixed to the outer wall of the side frame by bolts, and the output shaft drives the brush roller to rotate, which real-time combs the freshly sprayed adhesive layer, spreading out the accumulated adhesive and filling weak areas, eliminating the fluctuation in adhesive film thickness caused by uneven board surface, density differences, or uneven spraying. The flexible bristles of the brush roller contact the adhesive layer, which can effectively spread the adhesive without damaging the board surface, solving the problem that traditional equipment cannot achieve precision spraying alone. The fine-tuning process achieves stable clamping, continuous spraying, and dynamic combing of eco-friendly boards, effectively avoiding coating defects caused by board movement, uneven spraying, or adhesive accumulation. It improves bonding strength and the consistency of hot-press curing, reducing quality problems such as delamination and bubbling. It reduces adhesive waste and improves material utilization. It is easy to operate, adaptable to eco-friendly boards of different widths and thicknesses, and highly versatile. It meets the requirements of modern green board production for high uniformity and high stability coating processes. It is particularly suitable for processing eco-friendly boards with rough surfaces, loose structures, or easy deformation. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figure 1-5 , A highly uniform eco-friendly board gluing device includes a frame 1, and a support plate 3 is fixedly connected to the inner side of the frame 1, and a connecting plate 2 is slidably connected to the bottom of the support plate 3. The top of the support plate 3 is provided with clamping plates 5 on both sides, and the top of the two clamping plates 5 is fixedly connected to the top of the connecting plate 2. A cylinder 6 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and the output shaft of the cylinder 6 passes through the side wall of the frame 1 and is fixedly connected to one side of the connecting plate 2. A support plate 8 is slidably connected to the upper inner side of the frame 1, and a spray plate 9 is fixedly connected to the bottom of the support plate 8. A side frame 10 is fixedly connected to one side of the support plate 8. A brush roller 11 is rotatably connected to the inner side of the side frame 10. A drive motor 12 is fixedly connected to one side of the outer wall of the side frame 10 by bolts, and one end of the brush roller 11 passes through the side wall of the side frame 10 and is connected to the output shaft of the drive motor 12. A pump body 13 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and a support box 14 is fixedly connected to the side of the frame 1 near the pump body 13. The inlet of the pump body 13 is connected to one side of the support box 14, and the outlet of the pump body 13 is connected to one side of the spray plate 9.

[0021] When using the high-uniformity eco-friendly board gluing device, firstly, the eco-friendly board to be glued is placed stably on the support plate 3 fixedly connected to the inner side of the frame 1. The support plate 3 serves as a support platform for the board, ensuring its stable posture during the gluing process. Then, the cylinder 6, bolted to one side of the outer wall of the frame 1, is activated. The output shaft of the cylinder 6 passes through the side wall of the frame 1 and is fixedly connected to one side of the connecting plate 2, pushing the connecting plate 2 to move laterally along the sliding structure at the bottom of the support plate 3. Two clamping plates 5 are fixedly connected to the top of the connecting plate 2, and the clamping plates 5 move synchronously with the connecting plate 2. When the two clamping plates 5 approach each other, they apply adhesive to both sides of the eco-friendly board. The clamping and limiting mechanism, in conjunction with the inner wall of frame 1, forms a stable lateral constraint to prevent the board from shifting or vibrating during subsequent adhesive application. After clamping, the pump body 13, which is bolted to one side of the outer wall of frame 1, is activated. The inlet of pump body 13 is connected to a carrier box 14 fixed to one side of frame 1, drawing adhesive from the carrier box 14. The outlet is connected to a spray plate 9 fixed to the bottom of support plate 8 via a pipe, continuously delivering the adhesive to the inside of spray plate 9 and evenly spraying it out through the nozzle at the bottom of spray plate 9, forming an atomized or strip-shaped adhesive flow covering the upper surface of the eco-friendly board. At the same time, support plate 8 slides horizontally on the upper inner side of frame 1, driving spray plate 9. Moving along the length of the board, continuous and full-coverage spraying is achieved on the entire board, avoiding missed or recoated areas. Simultaneously or immediately after the adhesive spraying operation, the drive motor 12, bolted to one side of the outer wall of the side frame 10, is activated. The output shaft of the drive motor 12 is connected to one end of the brush roller 11 rotatably connected to the inner side of the side frame 10, driving the brush roller 11 to rotate at high speed. The bristles of the brush roller 11 contact the surface of the freshly sprayed adhesive layer, combing, spreading, and homogenizing the uncured adhesive, guiding locally accumulated adhesive to areas with insufficient adhesive, eliminating differences in adhesive film thickness, and making the adhesive layer distribution more even and continuous. The side frame 10 is fixed to the support plate. On one side of the support plate 8, the brush roller 11 moves synchronously with the support plate 8 to ensure that the combing action is consistent with the spraying path, forming a collaborative operation mode of spraying before brushing or spraying and brushing simultaneously. The entire equipment completes the entire process from material feeding, positioning and clamping, glue delivery, uniform spraying to surface combing through the coordinated work of the cylinder 6, connecting plate 2, clamping plate 5, bearing plate 3, pump body 13, bearing box 14, spray plate 9, support plate 8, side frame 10, drive motor 12 and brush roller 11. After the glue is applied, the pump body 13 and drive motor 12 are turned off, and the cylinder 6 retracts to drive the connecting plate 2 and clamping plate 5 to reset, making it easy to take out the glued material for subsequent assembly or hot pressing processes.

[0022] Furthermore, sliders 4 are fixedly connected to both sides of the top of the connecting plate 2, and both sliders 4 are slidably connected to the bearing plate 3 through the sliding groove 7. One side of each slider 4 is fixedly connected to one side of each clamping plate 5. When the cylinder 6 pushes the connecting plate 2 to move laterally along the bottom of the bearing plate 3, the sliders 4 are embedded in the sliding groove 7 on the bearing plate 3, forming a stable sliding guide pair. This ensures that the connecting plate 2 maintains linear motion during movement and avoids deflection or jamming due to uneven force. The sliders 4 are fixedly connected to the clamping plates 5, making the movement trajectory of the clamping plates 5 precise and controllable, ensuring that the two clamping plates 5 clamp or release the ecological board on both sides synchronously and smoothly. This structure improves the motion accuracy and stability of the clamping system and prevents the clamping plates 5 from tilting during clamping, which would cause uneven force on the board. This structure, together with the cylinder 6, connecting plate 2, and clamping plates 5, achieves the effects of providing stable sliding guidance, ensuring the synchronization of clamping actions, improving clamping accuracy, and enhancing the reliability of equipment operation.

[0023] Furthermore, a fixed frame 16 is fixedly connected to one side of the frame 1, and a screw 17 is rotatably connected to the inner side of the fixed frame 16. A nut seat 18 is threadedly connected to one end of the screw 17, and one side of the nut seat 18 is fixedly connected to one side of the support plate 8. The fixed frame 16 provides mounting support for the screw 17, and the screw 17 can rotate within the fixed frame 16. When the screw 17 is rotated manually or by an additional drive device, the nut seat 18 moves axially along the screw 17 under the action of the thread, thereby driving the support plate 8 fixedly connected to it. The support plate 8 slides horizontally on the upper inner side of the frame 1. This structure converts rotational motion into linear motion, enabling precise control of the movement position of the support plate 8 and ensuring that the movement paths of the spray plate 9 and brush roller 11 are uniform and stable. By adjusting the rotation angle of the screw 17, the stroke and speed of the support plate 8 can be precisely controlled to adapt to the gluing requirements of boards of different lengths. This structure, in conjunction with the spray plate 9 and brush roller 11, achieves the effects of precise linear movement of the support plate 8, improving the uniformity of spraying and combing, facilitating manual or automatic adjustment, and improving the gluing accuracy.

[0024] Furthermore, a sliding block 19 is fixedly connected to one side of the support plate 8, and the sliding block 19 is slidably connected to the side wall of the frame 1 through the sliding groove 20. The sliding block 19 is embedded in the sliding groove 20 of the side wall of the frame 1, providing auxiliary guidance and support for the lateral movement of the support plate 8. When the support plate 8 moves under the drive of the screw 17 and the nut seat 18, the sliding block 19 slides synchronously along the sliding groove 20, effectively preventing the support plate 8 from jumping up and down, swinging left and right or twisting during the movement, ensuring that it maintains a horizontal posture and stable operation. This structure enhances the smoothness and straightness of the movement of the support plate 8 and avoids the bending deformation caused by the cantilever structure. This structure, in conjunction with the screw 17 and the nut seat 18, achieves the effects of providing stable guiding support, preventing the support plate 8 from deviating, ensuring the smooth operation of the spray plate 9 and the brush roller 11, and improving the overall structural rigidity.

[0025] Furthermore, one end of the screw 17 is rotatably connected to the inner wall of the fixed frame 16 via a rotating shaft, and the other end of the screw 17 passes through the side wall of the fixed frame 16 via a bearing sleeve. One end of the brush roller 11 is rotatably connected to the inner wall of the side frame 10 via a rotating shaft, and the other end of the brush roller 11 passes through the side wall of the side frame 10 via a bearing sleeve.

[0026] Furthermore, a flexible hose 15 is connected to the outlet of the pump body 13, and one end of the hose 15 is connected to one side of the spray plate 9. The hose 15 serves as a flexible connector for adhesive delivery, with one end connected to the outlet of the pump body 13 and the other end connected to the spray plate 9. When the support plate 8 moves the spray plate 9 laterally along the frame 1, the hose 15 can bend and deform accordingly to adapt to the movement trajectory of the spray plate 9, preventing the rigid pipe from breaking, leaking, or obstructing movement due to movement. The hose 15 has good pressure resistance and chemical corrosion resistance, and can stably deliver adhesive, ensuring a continuous and stable supply of adhesive during the movement of the spray plate 9, and preventing interruption of adhesive supply. This structure, used in conjunction with the pump body 13 and the spray plate 9, achieves the effects of reliable adhesive supply connection between moving parts, avoiding pipe pulling damage, ensuring continuous adhesive supply, and improving the safety and stability of equipment operation.

[0027] In summary.

[0028] When using the high-uniformity eco-friendly board gluing device, firstly, the eco-friendly board to be glued is placed stably on the support plate 3 fixedly connected to the inner side of the frame 1. The support plate 3 serves as the main support platform for the board, ensuring it remains horizontal during the gluing process. Then, the cylinder 6, bolted to one side of the outer wall of the frame 1, is activated. The output shaft of the cylinder 6 passes through the side wall of the frame 1 and is fixedly connected to one side of the connecting plate 2, pushing the connecting plate 2 to move laterally along the bottom of the support plate 3. Slider 4 is fixedly connected to both sides of the top of the connecting plate 2. The two sliders 4 are respectively embedded in the grooves 7 on the support plate 3 to form a sliding fit, providing precise guidance for the connecting plate 2, ensuring it maintains linear motion during movement and preventing deflection or jamming. Two clamping plates 5 are fixedly connected to the top, and one side of each of the two sliders 4 is fixedly connected to one side of the two clamping plates 5 respectively. This ensures that the clamping plates 5 move towards the sides of the ecological board synchronously and smoothly with the connecting plate 2, achieving stable clamping and limiting of the board edge. This, together with the inner wall of the frame 1, forms a reliable lateral constraint, preventing it from shifting or vibrating during subsequent glue application. After clamping, the pump body 13, which is fixedly connected to one side of the outer wall of the frame 1 by bolts, is activated. The inlet of the pump body 13 is connected to the bearing box 14 fixed to one side of the frame 1, and adhesive is drawn from the bearing box 14. The outlet is connected to the spray plate 9 fixed at the bottom of the support plate 8 through a hose 15. The hose 15, as a flexible delivery pipe, can be freely bent and deformed during the movement of the support plate 8 to adapt to dynamic position changes. This ensures a continuous and stable supply of adhesive to the spray plate 9, which is then evenly sprayed through nozzles to cover the surface of the eco-friendly board. Simultaneously, the support plate 8 moves horizontally along the upper inner side of the frame 1. This movement is supported by a fixed frame 16 fixedly connected to one side of the frame 1. A screw 17 is rotatably connected to the inner side of the fixed frame 16. One end of the screw 17 is connected to the inner wall of the fixed frame 16 via a rotating shaft, and the other end passes through the side wall of the fixed frame 16 via a bearing sleeve, facilitating external rotational force. A nut seat 18 is threadedly connected to the screw 17. One side of the nut seat 18 is fixedly connected to one side of the support plate 8. When the screw 17 is rotated manually or via a drive mechanism, the nut seat 18 moves axially along the screw 17, causing the support plate 8 to move synchronously. One side of the support plate 8 is also fixedly... A sliding block 19 is fixedly connected to the support plate 8. The sliding block 19 is embedded in the sliding groove 20 on the side wall of the frame 1 to form a sliding guide pair, which provides auxiliary support for the movement of the support plate 8 and effectively prevents it from jumping up and down, swinging left and right or twisting during the movement, ensuring smooth operation and straightness of the trajectory. As the support plate 8 moves, the spray plate 9 fixed at its bottom continuously scans and sprays along the length of the board to achieve full coverage of the entire board with glue, avoiding missed coating or recoating. At the same time, the side frame 10 fixedly connected to one side of the support plate 8 moves synchronously. A brush roller 11 is rotatably connected to the inside of the side frame 10. One end of the brush roller 11 is connected to the inner wall of the side frame 10 through a rotating shaft, and the other end passes through the side wall of the side frame 10 through a bearing sleeve, forming a double-end support structure to improve rotational stability and coaxiality.The drive motor 12, which is bolted to one side of the outer wall of the side frame 10, has its output shaft connected to the end of the brush roller 11. After starting, it drives the brush roller 11 to rotate at high speed. The bristles contact the freshly sprayed adhesive layer, combing, spreading and redistributing the adhesive in real time, guiding the adhesive from the local accumulation area to the lack of adhesive, eliminating thickness differences and improving the uniformity of the adhesive film. The entire equipment completes the entire process from material feeding, positioning and clamping, adhesive delivery, reciprocating spraying to dynamic combing through the coordinated work of components such as the bearing plate 3, connecting plate 2, slider 4, slide groove 7, clamping plate 5, cylinder 6, spray plate 9, hose 15, pump body 13, bearing box 14, support plate 8, sliding block 19, sliding groove 20, fixed frame 16, screw 17, nut seat 18, side frame 10, brush roller 11, and drive motor 12. After the adhesive is applied, the pump body 13 and drive motor 12 are turned off, and the cylinder 6 retracts, driving the connecting plate 2 and clamping plate 5 to reset, making it easy to remove the coated material for the next process. By installing a clamping system driven by a cylinder 6 inside the frame 1, the problem of poor bonding quality caused by unstable clamping and uneven coating in existing glue application devices is solved. The support plate 3 is fixed to the inside of the frame 1, providing stable support for the eco-friendly board and preventing it from bending and deforming due to its own weight or external force during the glue application process. The cylinder 6 is fixed to the outer wall of the frame 1 by bolts, and the output shaft pushes the connecting plate 2 to move laterally, thereby driving the clamping plate 5. The sliders 4 on both sides of the top of the connecting plate 2 are embedded in the grooves 7 on the support plate 3, forming a stable sliding guide structure to ensure that the connecting plate 2 moves smoothly and accurately, avoiding uneven clamping force due to deviation. The sliders 4 are fixedly connected to the clamping plate 5, so that the two clamping plates 5 move synchronously and clamp the two sides of the board evenly, effectively preventing vibration and displacement during the glue application process. The pump body 13 is fixed to the outer wall of the frame 1 by bolts, the inlet is connected to the support box 14 to realize centralized storage and stable supply of glue, and the outlet is connected to the spray nozzle through the hose 15. The plate 9 is connected, and the hose 15 has good flexibility and corrosion resistance. It can bend freely during the movement of the support plate 8, avoiding the breakage of rigid pipes or obstruction of movement, and ensuring continuous and reliable glue supply. The spray plate 9 is fixed to the bottom of the support plate 8 and moves along the length of the board to achieve continuous scanning spraying, which significantly improves the coverage and consistency of the glue coating area and reduces missed coating or overlap. The movement of the support plate 8 is driven by the screw 17 and the nut seat 18 in the fixed frame 16. One end of the screw 17 is connected through a rotating shaft, and the other end passes through the side wall of the fixed frame 16 through a bearing sleeve. The structure is stable and facilitates power input. Rotating the screw 17 can accurately control the axial displacement of the nut seat 18, thereby adjusting the stroke and speed of the support plate 8 to meet the glue coating needs of different specifications of boards. The sliding block 19 on one side of the support plate 8 is embedded in the sliding groove 20 on the side wall of the frame 1, providing additional guiding support to prevent the support plate 8 from deflecting or shaking due to cantilever force, and ensuring the smooth operation of the spray plate 9 and the brush roller 11.The side frame 10 is fixed to one side of the support plate 8. The brush roller 11 installed inside is supported at both ends by a rotating shaft and bearing sleeve structure on the inner wall of the side frame 10, forming a double-end support. This significantly improves its rotational accuracy and operational stability, preventing vibration from affecting the combing effect. The drive motor 12 is fixed to the outer wall of the side frame 10 by bolts. The output shaft drives the brush roller 11 to rotate at high speed. The bristles flatten and redistribute the wet adhesive layer, effectively eliminating uneven adhesive film thickness caused by uneven board surface, density differences, or spraying fluctuations. The "spray first, brush later" composite process significantly improves the flatness, continuity, and coverage integrity of the adhesive layer, solving the problem of traditional equipment relying solely on spraying for precise control. The entire device has a compact structure, with all components operating in coordination, achieving stable clamping, continuous spraying, and dynamic combing of the eco-friendly boards. This effectively avoids coating defects caused by board movement, uneven spraying, or adhesive accumulation. It improves bonding strength and the consistency of hot-press curing, reducing quality problems such as delamination and bubbling. It also reduces adhesive waste and improves material utilization.
