Description

Technical Field

[0001] This utility model relates to the field of plywood processing technology, specifically to a glue-applying device for plywood processing. Background Technology

[0002] Plywood is made by gluing together multiple layers of thin wood veneers with vertically stacked grain. Its thickness can vary depending on the number of veneers used. The adhesives used in plywood are mostly liquid adhesives, and depending on the equipment used, they can be divided into roller coating, drip coating, extrusion coating, and pressure spraying.

[0003] During the patent application process, a search revealed a Chinese patent with patent number CN215702492U: an automatic glue-applying device for plywood processing, comprising: a first support plate, a second support plate mounted above the first support plate, and a support frame fixedly connected to the front surface of the first support plate. Several glue dispensing heads are installed through the interior of the support frame. A moving component is provided on the upper surface of the first support plate, and a cleaning component is provided on the right side surface of the support frame. This invention, by incorporating the moving component, allows the motor within the moving component to rotate the lead screw, which in turn drives the first connecting block to move the second support plate to the right. Activating the glue pump then dispenses glue into the glue dispensing heads to apply it to the plywood. The entire process is fully automated. After glue application, the worker can move the mounting bracket in the cleaning component to the left, ensuring the absorbent cotton on the mounting bracket is aligned with the glue dispensing heads, preventing glue dripping from the dispensing heads from contaminating the working environment.

[0004] The above-mentioned solution applies glue to the board through a glue dispensing head during use. However, there are gaps between the glue dispensing heads, which can easily lead to uneven glue distribution and accumulation on the top of the board. In addition, the glue application height of this device is limited and cannot be adjusted, which means it cannot apply glue to plywood of different thicknesses. Therefore, it has low practicality and cannot meet people's needs. Utility Model Content

[0026] The glue application assembly 5 includes a glue application box 501, and a glue injection port is provided on one side of the glue application box 501. The glue application box 501 is fixedly connected to the lower end of the mounting plate 404. Support plates 502 are fixedly connected to both sides of the glue application box 501. A rotating shaft 503 is rotatably connected between the two support plates 502. A glue application roller 504 is fixedly connected to the outer wall of the rotating shaft 503. A gear 505 is fixedly connected to the outer wall of one end of the rotating shaft 503 through the support plate 502. A rotating shaft 506 is rotatably connected to the inner bottom of the glue application box 501. A discharge roller 507 is fixedly connected to the outer wall of the rotating shaft 506. The discharge roller 507 is located above the glue application roller 504, and the outer wall of the discharge roller 507 and the glue application roller 504 are in contact. A gear 508 is fixedly connected to the outer wall of one end of the rotating shaft 506 through the glue application box 501 and the support plate 502. The glue application component 5 can evenly apply glue to the plywood.

[0027] Gear 2 508 is located above gear 1 505, and gear 2 508 is meshed with gear 1 505. Gear 2 508 is driven by gear 1 505 to rotate, so that the discharge roller 507 and the glue coating roller 504 rotate synchronously.

[0028] A motor 5021 is fixedly connected to one side of a support plate 502. The output end of the motor 5021 passes through the support plate 502 and is fixedly connected to a rotating shaft 503. The rotating shaft 503 is driven to rotate by the motor 5021.

[0029] The gantry frame 3 has sliding grooves 301 on both its front and rear sides.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, the plywood to be processed is placed on the placement plate 2. The electric push rod 102 is activated, pushing the guide block 103 to slide along the groove 101, thereby moving the plywood on the placement plate 2 until it is positioned directly below the gantry frame 3. At this time, the motor 6 is activated, driving the bidirectional threaded rod 401 to rotate, causing the two threaded sleeves 402 to move in opposite directions. Simultaneously, the connecting rod 403 is rotatably connected to the mounting seat 405 on the mounting plate 404, thus pushing the mounting plate 404 downwards. During this movement, the mounting plate 404... The slider 303 slides along the guide rod 302 to ensure the stability of the lifting process. When applying glue, the motor 5021 is started to drive the rotating shaft 503 to rotate. The rotating shaft 503 drives the gear 505 to rotate. Through the meshing of the gear 505 and the gear 508, the gear 508 is driven to rotate, thereby driving the rotating shaft 506 and the discharge roller 507 to rotate. At this time, the discharge roller 507 evenly applies glue to the outer wall of the glue application roller 504. The glue application roller 504 contacts the surface of the plywood and evenly applies glue to the plywood.
