Description

Technical Field

[0001] This utility model relates to the field of adhesive coating device technology, specifically a homogeneous plywood adhesive coating device. Background Technology

[0002] Plywood is a composite board made of three or more layers of thin wood veneers bonded together with adhesive. The wood fibers of adjacent veneers are perpendicular to each other. This structure gives plywood excellent stability and strength. In the production process of plywood, hot pressing is usually used to ensure the board's firmness and durability.

[0003] Roller coating is a method of applying adhesive evenly to the surface of a veneer using rollers. The amount of adhesive applied is controlled by adjusting the roller spacing and pressure. In common roller coating methods, the adhesive is stored between the two rollers. This storage space is relatively small, which leads to frequent replenishment. In order to avoid overflowing from the outer edge of the rollers, not too much adhesive is applied at a time, resulting in frequent refilling. Furthermore, if manual refilling is not timely, it will lead to insufficient adhesive and uneven coating. Utility Model Content

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: including a conveyor frame 1 and a coating roller 3. A set of conveyor rollers 11 are rotatably connected inside the conveyor frame 1. A lifting frame 2 is installed above the conveyor frame 1. A lifting component is provided on the outside of the lifting frame 2. Two coating rollers 3 that are in close contact with each other are rotatably connected inside the lifting frame 2. The two coating rollers 3 have different diameters. A pair of baffles 6 are installed between the coating rollers 3. A glue storage tank 4 is provided between the baffles 6. A material box 5 is fixed between the lifting frames 2 and above the glue storage tank 4. Liquid replenishment ports 54 are evenly arranged at the bottom of the material box 5. An adjustment component for adjusting the feeding speed is provided. A stabilizing frame 21 is fixed between the lifting frames 2. The material box 5 is fixed on the stabilizing frame 21. A drive device for driving the coating rollers 3 to rotate is fixed on the outside of the lifting frame 2.

[0019] The adjustment assembly includes an adjustment groove 51, which is located at the bottom of the material box 5. The liquid inlet 54 is located above the adjustment groove 51. An adjustment plate 52 is slidably connected inside the adjustment groove 51, and its upper surface abuts against the adjustment groove 51. Adjustment holes 53 are equidistantly opened on the adjustment plate 52. The size of the adjustment holes 53 corresponds one-to-one with the liquid inlet 54, and they have the same diameter. A liquid level sensor 58 is fixed on the upper inner side of the material box 5. A threaded rod 55 is rotatably connected to one end of the adjustment groove 51, and a guide rod 56 is fixed to the other end. The end of the guide rod 56 is slidably connected inside the adjustment plate 52. The end of the threaded rod 55 is threadedly connected inside the adjustment plate 52. One outer end of the threaded rod 55 extends out of the adjustment groove 51 and is fixedly connected to a rotating plate 57. Rotating the rotating plate 57 causes the threaded rod 55 to rotate, which in turn causes the adjustment plate 52 to slide horizontally, causing the overlap between the liquid inlet 54 and the adjustment hole 53 to change.

[0020] The lifting assembly includes a fixed bracket 7 and a synchronous hydraulic cylinder 73. The fixed bracket 7 is fixed to the upper end of the conveyor frame 1 and located outside the lifting frame 2. The fixed bracket 7 has a lifting groove 71, and a lifting block 72 is slidably connected in the lifting groove 71. The inner side of the lifting block 72 is fixedly connected to the lifting frame 2. The synchronous hydraulic cylinder 73 is fixed to the upper end of the fixed bracket 7, and its output end is fixed to the lifting block 72. A controller 74 is fixedly connected to the outer side of the fixed bracket 7. The bottom of the lifting frame 2 is slidably connected inside the conveyor frame 1. Driven by the synchronous hydraulic cylinder 73, the lifting frame 2 can be lifted and lowered, thereby changing the height of the coating roller 3. This is suitable for processing plates of different thicknesses.

[0021] Working Principle: First, connect the entire device to an external power source. Then, store the glue in the material tank 5. At this time, the glue in the material tank 5 will enter the glue storage tank 4 through the replenishment port 54. Then, place the board on the conveyor roller 11 for conveying, and drive the glue application roller 3 to rotate. As the glue application roller 3 passes over the surface of the board, it rolls over the surface of the board to achieve the purpose of glue application. During this process, the lifting frame 2 can be raised and lowered by the synchronous hydraulic cylinder 73, thereby changing the height of the glue application roller 3. This is suitable for processing boards of different thicknesses. During the glue application process, the glue in the material tank 5 will continuously enter the glue storage tank 4, eliminating the need for frequent... The feeding process is simpler and avoids uneven glue application due to insufficient glue. Furthermore, when processing boards with different glue application amounts, the feeding speed of the material box 5 can be adjusted to ensure that there is always glue in the glue storage tank 4 without excessive glue overflow. During operation, simply rotate the rotating plate 57, which drives the threaded rod 55 to rotate, thereby causing the adjusting plate 52 to slide horizontally. This changes the overlap between the liquid replenishment port 54 and the adjusting hole 53. The larger the overlap area, the faster the glue feeding speed, and vice versa. This achieves the adjustment purpose, ensuring that there is always glue in the glue storage tank 4 without exceeding the upper edge of the glue application roller 3.
