Description

Technical Field

[0001] This utility model belongs to the field of veneer MDF production technology, and in particular relates to an automatic glue application device for veneer MDF. Background Technology

[0002] As a widely used basic material in modern furniture manufacturing and interior decoration, veneered MDF usually needs to be covered with wood veneer, decorative paper or fireproof board and other decorative materials to improve its aesthetics and functionality. In this veneer process, glue application is a crucial step, and its quality directly affects the bonding strength between the decorative material and the MDF substrate and the flatness of the final product. Automatic glue application equipment is used during glue application.

[0003] Existing automatic gluing devices generally adopt a glue-applying roller structure. Their working principle is as follows: a motor drives the glue-applying roller to rotate at a uniform speed. During rotation, the lower part of the roller is immersed in a glue tank containing adhesive to pick up sufficient glue. It then contacts the bottom surface of the MDF (medium-density fiberboard) passing above it, and through rolling friction, the glue is continuously and evenly applied to the surface of the board. After the gluing operation is completed, unused glue remains on the surface of the glue-applying roller and the inner wall of the glue tank. Once this glue hardens, it is extremely difficult to remove. Thorough cleaning is required after each production break or at the end of each workday. Because the glue-applying roller and glue tank have a large area, the cleaning workload is increased. Furthermore, the glue-applying roller has a fixed size and cannot be adjusted according to the size of the MDF, resulting in the need to add a large amount of glue each time, wasting resources.

[0004] To address this issue, we provide an automatic adhesive application device for laminated MDF, which solves the aforementioned problems. Utility Model Content

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0026] Please see Figures 1-5 This utility model relates to an automatic glue application device for laminated MDF, comprising a base plate 1, a support plate 2 fixedly connected to the top of the base plate 1, a glue application roller 3 rotatably connected to one side of the support plate 2, a conveying roller 4 mounted on the top of the glue application roller 3, a glue trough 5 mounted on the bottom of the glue application roller 3, a discharge pipe 6 connected to the bottom of the glue trough 5, a pipe cap 7 threadedly connected to the surface of the discharge pipe 6, a drive mechanism 8 mounted on one side of the glue application roller 3, and a scraping mechanism 9 mounted on the top of the glue trough 5. The scraping mechanism 9 includes a scraper 91 sleeved on the surface of the glue application roller 3, a support frame 92 fixedly connected to one side of the scraper 91, and a fixing plate 93 fixedly connected to one side of the support frame 92. The bottom of the glue tank 5 is provided with an adjustment mechanism 10. The adjustment mechanism 10 includes a housing 1001 fixedly connected to the top of the base plate 1, a servo motor 1002 rotatably connected to one side of the housing 1001, a threaded rod 1003 fixedly connected to the output end of the servo motor 1002, a threaded sleeve 1004 threadedly connected to the surface of the threaded rod 1003, a connecting frame 1005 fixedly connected to the top of the threaded sleeve 1004, a connecting plate 1006 fixedly connected to one side of the connecting frame 1005, an active slot 1007 opened on the top of the housing 1001, and a bracket 1008 fixedly connected to one side of the servo motor 1002.

[0027] As a preferred embodiment of the above: The bottom plate 1 has mounting holes at its top. The glue-applying roller 3 and the conveying roller 4 extend from the side near the drive motor 82 to the side of the support plate 2 near the drive motor 82. The extended ends of the glue-applying roller 3 and the conveying roller 4, as well as the ends of the glue-applying roller 3 and the conveying roller 4 away from the drive motor 82, are rotatably connected to the support plate 2 via bearings. The output end of the servo motor 1002 is rotatably connected to the housing 1001 via bearings. The threaded rod 1003 is rotatably connected to the housing 1001 via bearings. The top of the connecting frame 1005 extends through to the top of the housing 1001. The support plate 2 is used to install and support key components such as the glue-applying roller 3 and the conveying roller 4, ensuring accurate positioning and stable operation. The glue-applying roller 3 dips into the glue tank 5 by rotating and evenly applies the glue to the bottom surface of the veneer MDF. The conveying roller 4 cooperates with the glue-applying roller 3. The glue tank 5 stores the glue liquid for the glue roller 3 to pick up. The discharge pipe 6 and pipe cover 7 are used to discharge the unused glue liquid in the glue tank 5 for easy cleaning and maintenance. The scraper 91 scrapes off the excess glue liquid on the surface of the glue roller 3 for easy cleaning. The support frame 92 supports the scraper 91. The servo motor 1002 drives the threaded rod 1003 to rotate, realizing the adjustment of the position of the scraper 91. The threaded rod 1003 and threaded sleeve 1004 convert the rotational motion into linear motion, driving the scraper 91 to move. The connecting frame 1005 and connecting plate 1006 connect the scraper 91 to the adjustment mechanism 10 to transmit motion. The movable groove 1007 allows the connecting frame 1005 to move on the top of the box 1001 to adapt to the position change of the scraper 91. The bracket 1008 fixes the servo motor 1002 to ensure its stable operation. Example

[0028] Please see Figures 1-5 Based on Embodiment 1, the drive mechanism 8 includes gears 81 fixedly connected to the surfaces of the coating roller 3 and the conveying roller 4, a drive motor 82 fixedly connected to one side of the conveying roller 4, a fixed bracket 83 fixedly connected to one side of the drive motor 82, a slider 11 fixedly connected to the bottom of the threaded sleeve 1004, the slider 11 being slidably connected to the bottom of the housing 1001, a bracket 1008 fixedly connected to the housing 1001, the threaded rod 1003 being rotatably connected to the housing 1001 at one end away from the servo motor 1002, the coating roller 3 and the glue tank 5 being in close contact with the scraper 91, the glue tank 5 being fixedly connected to the support plate 2, the conveying roller 4 being rotatably connected to the support plate 2, the fixed plate 93 being fixedly connected to the connecting plate 1006 by bolts, the output end of the drive motor 82 being fixedly connected to the conveying roller 4, and the two gears 81 meshing with each other.

[0029] As a preferred embodiment of the above embodiment: a groove adapted to the slider 11 is provided at the bottom of the housing 1001, the fixing frame 83 is fixedly connected to the support plate 2, the gear 81 transmits power to ensure that the glue coating roller 3 and the conveying roller 4 rotate synchronously, the drive motor 82 provides power to drive the conveying roller 4 and the glue coating roller 3 to operate, and the fixing frame 83 fixes the drive motor 82 to ensure its stable operation.

[0030] The working principle of this utility model is as follows: First, according to the width of the MDF to be glued, the servo motor 1002 is started. Through the transmission of the threaded rod 1003 and the threaded sleeve 1004, the connecting frame 1005 and the scraper 91 fixed thereon are moved along the direction of the movable groove 1007. The distance between the two scrapers 91 is adjusted to a suitable position. Then, the glue is injected into the area between the two scrapers 91 in the glue tank 5. The drive motor 82 is started. Through the transmission of the gear 81, the conveying roller 4 and the glue coating roller 3 are driven to rotate synchronously. The MDF is guided forward by the conveying roller 4. During the rotation, the glue coating roller 3 picks up the glue and evenly coats it on the bottom surface of the board. During the glue coating process, the scraper 91 plays a limiting and guiding role for the board to prevent it from deviating. The glue is added to the area between the two scrapers 91 to reduce the cleaning area.

[0031] After the glue application is completed, open the pipe cover 7 on the discharge pipe 6 to discharge the remaining glue in the glue tank 5. Then, start the servo motor 1002 again to move the scraper 91 towards the center to scrape off the glue residue on the surface of the glue roller 3 and the inner wall of the glue tank 5, further reducing the area to be cleaned. Finally, only the scraper 91 and a small contact area need to be cleaned to complete the entire cleaning process, achieving efficient and energy-saving glue application and maintenance operations.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
