Description

Technical Field

[0001] This utility model relates to the field of automatic glue application technology, specifically to an automatic glue application device for multi-layer plywood. Background Technology

[0002] Plywood is a sheet material consisting of three or more layers of wood, either rotary-cut into veneers or sliced ​​into thin sheets and then glued together with adhesive. It typically uses an odd number of veneer layers, with the grain direction of adjacent veneers perpendicular to each other. Plywood is one of the most commonly used materials in furniture making and is one of the three major types of engineered wood products. It is also used in aircraft, ships, trains, automobiles, construction, and packaging. Automatic gluing equipment is required in the production of plywood.

[0003] Existing automatic glue applicators can only limit and fix plywood of specific sizes. When dealing with plywood of different sizes, different clamps need to be changed, which cannot provide a stable limiting and fixing effect. This increases the number of operating steps for workers and reduces the practicality of the automatic glue applicator. Utility Model Content

[0004] This invention provides an automatic gluing device for multi-layer plywood, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0021] The above technical solution can make the connection between the connecting block and the lifting plate more stable.

[0022] Furthermore, a spring is fixedly connected to the side of the two square plates that are close to each other.

[0023] The above technical solution facilitates the rapid reset of the slide bar.

[0035] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0036] like Figures 1 to 6 As shown, an embodiment of this utility model provides an automatic gluing device for multi-layer plywood, comprising: a workbench 1, a drive frame 2 fixedly connected to the upper surface of the workbench 1, a storage box 3 fixedly connected to the upper end of the drive frame 2, a hydraulic cylinder 4 installed on the inner wall of the drive frame 2, a lifting plate 5 fixedly connected to the output end of the hydraulic cylinder 4, a support frame 9 fixedly connected to the surface of the lifting plate 5, a glue-applying roller 10 provided on the inner wall of the support frame 9, a glue inlet pipe 8 limiting mechanism 6 provided on the side of the storage box 3 and the lifting plate 5 that are close to each other, which is set on the surface of the workbench 1 for fixing plywood of different sizes; and a scraping mechanism 7, which is set on the surface of the lifting plate 5 for evenly scraping the glue applied to the plywood.

[0037] like Figures 1 to 4 As shown, the limiting mechanism 6 includes a square groove 612, which is formed on the inner wall of the worktable 1. A bidirectional screw 602 is rotatably connected to the inner wall of the square groove 612. A motor 604 is fixedly connected to the surface of the worktable 1. The output end of the motor 604 is fixedly connected to the bidirectional screw 602. Two movable frames 605 are threadedly connected to the arc surface of the bidirectional screw 602. A rectangular groove 601 is formed on the inner wall of the worktable 1. The rectangular groove 601 is slidably connected to the movable frames 605. Two sliders 606 are slidably connected to the inner wall of the movable frames 605. A lead screw 607 is threadedly connected to the inner wall of the sliders 606. A throttle 608 is fixedly connected to one end of the lead screw 607. A limiting plate 610 is rotatably connected to the other end of the lead screw 607. When applying glue to plywood, the worker places the plywood on the workbench 1, then starts the motor 604, which drives the two moving frames 605 to move within the square groove 612 and rectangular groove 601 via the bidirectional screw 602. Once the frames are in the appropriate position, the motor 604 is turned off. Then, the slider 606 on the moving frame 605 is slid to move it to the appropriate position. The screw 607 is rotated by the throttle 608, which moves the limiting plate 610 to contact the surface of the workbench 1, thus fixing the position of the limiting plate 610 and limiting the four sides of the plywood. This achieves the effect of limiting and fixing plywood of different sizes. Then, the hydraulic cylinder 4 drives the lifting plate 5 to fall, allowing the glue application roller 10 in the support frame 9 to adhere to the surface of the plywood. The glue in the storage box 3 is sprayed onto the glue application roller 10 through the glue inlet pipe 8. Finally, the drive frame 2 drives the glue application roller 10 to rotate, applying the glue to the plywood.

[0038] like Figures 1 to 4 As shown, a fixing rod 603 is fixedly connected to the inner wall of the rectangular groove 601, and the fixing rod 603 slides through the movable frame 605. When the two movable frames 605 move, the fixing rod 603 allows the movable frames 605 to move smoothly under the drive of the motor 604.

[0039] like Figures 1 to 4 As shown, a telescopic rod 609 is fixedly connected to the surface of the slider 606, and the output end of the telescopic rod 609 is fixedly connected to the limiting plate 610. When the lead screw 607 drives the limiting plate 610 to move, the telescopic rod 609 also extends and retracts accordingly, so that the limiting plate 610 can only move up and down.

[0040] like Figures 1 to 4 As shown, a rubber pad 611 is fixedly connected to the surface of the limiting plate 610. When the limiting plate 610 is attached to the plywood, the rubber pad 611 makes the limiting plate 610 more stable in limiting the plywood.

[0041] In this embodiment of the utility model (working principle), by setting the limiting mechanism 6, when it is necessary to apply glue to the plywood, the worker places the plywood on the workbench 1, and then starts the motor 604. The two-way screw 602 drives the two moving frames 605 to move within the square groove 612 and the rectangular groove 601. The presence of the fixing rod 603 not only provides stable guidance for the moving frames 605, but also allows the moving frames 605 to move smoothly under the drive of the two-way screw 602. When the two moving frames 605 move to the appropriate position, the motor 604 is turned off. Then, the slider 606 on the moving frame 605 is slid to move it to the appropriate position. The screw 607 is rotated by the throttle 608, which then... The movable limit plate 610 moves, and the telescopic rod 609 makes the limit plate 610 only move up and down. The bottom surface of the limit plate 610 contacts the surface of the worktable 1, and the screw 607 stops rotating, thereby fixing the position of the limit plate 610 and limiting the four sides of the plywood. The rubber pad 611 makes the limit plate 610 more stable in limiting the plywood and avoids the possibility of damaging the surface of the plywood. Then, the hydraulic cylinder 4 drives the lifting plate 5 to fall, so that the glue roller 10 in the support frame 9 is in contact with the surface of the plywood. The glue in the storage box 3 is sprayed onto the glue roller 10 through the glue inlet pipe 8. Finally, the drive frame 2 drives the glue roller 10 to rotate and apply the glue to the plywood.

[0042] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the scraping mechanism 7 includes a limiting groove 72, which is formed on the surface of the lifting plate 5. A connecting block 71 is installed on the inner wall of the limiting groove 72, and a scraper 78 is slidably connected to the inner wall of the connecting block 71. Several springs 79 are fixedly connected to the side of the connecting block 71 and the scraper 78 that are close to each other. When it is necessary to scrape the glue on the plywood, the connecting block 71 is engaged with the limiting groove 72, so that the scraper 78 is also fixed on the lifting plate 5. When the glue roller 10 applies glue to the plywood, the scraper 78 is pressed by the springs 79 to contact the plywood surface. As the glue roller 10 moves, the scraper 78 also moves, scraping the glue on the plywood evenly. When it is necessary to clean the scraper 78, the connecting block 71 is removed, so that the scraper 78 can be cleaned easily.

[0043] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the surface of the connecting block 71 has a sliding groove 74, and two sliding rods 75 are slidably connected to the inner wall of the sliding groove 74. One end of the sliding rod 75 is fixedly connected to a square plate 76. The inner wall of the limiting groove 72 has two round holes 73, the size of which matches the size of the sliding rods 75. When the connecting block 71 is to be connected to the limiting groove 72, the two sliding rods 75 in the sliding groove 74 move relative to each other through the sliding of the square plate 76, and then the connecting block 71 is engaged with the limiting groove 72. Pulling the two square plates 76 causes the sliding rods 75 to engage with the round holes 73, thus fixing the position of the connecting block 71.

[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, spring 77 is fixedly connected to the side of the two square plates 76 that are close to each other. When the slide rod 75 is to engage with the round hole 73, the spring 77 allows the slide rod 75 to quickly engage with the round hole 73.

[0045] In this embodiment of the utility model, by setting a scraping mechanism 7, when it is necessary to scrape the glue on the plywood, the two square plates 76 are squeezed to drive the two sliding movements. At this time, the spring 77 is compressed, and the connecting block 71 is engaged with the limiting groove 72. The square plates 76 are released, and under the action of the spring 77, the two sliding rods 75 are quickly engaged with the corresponding round holes 73, thereby fixing the position of the connecting block 71. When the glue roller 10 applies glue to the plywood, the scraper 78 in the connecting block 71 is squeezed by the spring 79 to contact the plywood surface. As the glue roller 10 moves, the scraper 78 also moves, thereby scraping the glue on the plywood evenly. When it is necessary to clean the scraper 78, the sliding rods 75 are disengaged from the round holes 73 by squeezing the square plates 76, and the connecting block 71 is fixed. The connecting block 71 can then be removed, thus facilitating the cleaning of the scraper 78.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
