Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment, and in particular to a high-speed rotating adhesive coating equipment for laminated plywood. Background Technology

[0002] Laminated plywood refers to plywood with a laminated film applied to an aluminum alloy substrate. This film is made by laminating a high-gloss or iridescent film onto the surface of the board with a professional adhesive. Laminated plywood has a vibrant sheen, a wide variety of colors and patterns to choose from, and is waterproof, fireproof, and possesses excellent durability (weather resistance, corrosion resistance, chemical resistance) and stain resistance, as well as superior UV protection. Different brands of laminated plywood vary in their substrate material and thickness, as well as the material and thickness of the laminate. There are also architectural laminated plywoods made from materials such as poplar.

[0003] Chinese patent CN219129764U discloses a gluing device for producing laminated plywood, comprising a support frame, an electric conveyor belt installed inside the support frame, a gantry frame spanning both sides of the electric conveyor belt mounted on top of the support frame, a T-shaped frame snapped into the inside of the gantry frame, a glue dispensing pipe connected to the bottom of the T-shaped frame, a pull plate connected to the side of the T-shaped frame, and a long grooved ring connected to the front end of the pull plate. This gluing device for producing laminated plywood uses a drive motor to rotate a turntable, causing a short rod to move the long grooved ring back and forth, which in turn moves the T-shaped frame and the glue dispensing pipe back and forth. This allows the glue spray head to spray S-shaped patterns of glue onto the substrate, ensuring that the lateral projections of the glue intersect. When the glue roller applies the glue laterally, the glue adheres together, preventing gaps in the application.

[0004] The aforementioned device allows the lateral projections of the adhesive to intersect, ensuring that the adhesive adheres together when the subsequent coating roller applies the adhesive, thus preventing gaps in the application. However, when the laminated plywood is coated by the coating roller, the adhesive on the laminated plywood is easily squeezed out from the side of the laminated plywood, tending to stick to the side of the laminated plywood, resulting in an uneven appearance and affecting aesthetics. If it falls onto the transport device, it is inconvenient to clean. Utility Model Content

Detailed Implementation

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

[0026] Example 1

[0027] Reference Figures 1 to 5 A high-speed rotating coated plywood gluing device includes a base 1, a belt conveyor 2 installed on the inner side of the base 1, a first mounting frame 3 installed between the top two sides of the base 1, and a gluing component provided on the first mounting frame 3.

[0028] A second mounting bracket 4 is installed on the top side of the base 1 away from the first mounting bracket 3. An elastic moving component is provided on the second mounting bracket 4. A first mounting plate 5 is installed on one end of the elastic moving component. A glue-applying roller 6 is rotatably connected to the first mounting plate 5. Two glue-blocking blocks 7 are fixedly installed on the first mounting plate 5. The two glue-blocking blocks 7 are located on both sides of the glue-applying roller 6, and the two glue-blocking blocks 7 are in contact with the sides of the glue-applying roller 6. The glue-blocking blocks 7 are disc-shaped, and the bottom of the glue-blocking blocks 7 is horizontal. The bottom of the glue-blocking blocks 7 is in contact with the surface of the conveyor belt of the belt conveyor device 2.

[0029] In use, this device places the laminated plywood onto the belt conveyor 2, allowing it to pass under the adhesive applicator. Adhesive is applied to the top of the laminated plywood, and the belt conveyor 2 moves it under the adhesive applicator roller 6, allowing it to pass through the roller and have the adhesive smoothed. Compared to existing technologies, this device, with its adhesive-blocking block 7, can smooth the adhesive on the laminated plywood using the adhesive applicator roller 6. When the applicator roller squeezes the adhesive, the adhesive-blocking block 7 limits the amount of adhesive at the edges of the laminated plywood, preventing it from being squeezed out and falling onto the conveyor belt of the belt conveyor 2, thus solving the problems of adhesive easily being squeezed out from the sides of the laminated plywood, sticking to the sides, and falling onto the conveyor device for easy cleaning in existing technologies.

[0030] Furthermore, the adhesive application assembly includes an adhesive application tank 10, a connecting pipe 11, a first connecting plate 12, and a plurality of nozzles 13. The adhesive application tank 10 is mounted on a first mounting frame 3. A first suction assembly 14 is provided on one side of the adhesive application tank 10. The connecting pipe 11 is located on one side of the first suction assembly 14. The first connecting plate 12 is mounted on the first mounting frame 3. The other side of the connecting pipe 11 is connected to the first connecting plate 12. The plurality of nozzles 13 are located at the bottom of the first connecting plate 12 and are evenly connected to the connecting pipe 11. Through the first suction assembly 14, when the laminated plywood passes under the nozzles 13, the adhesive in the adhesive application tank 10 can be drawn through the connecting pipe 11 and sprayed from the nozzles 13 onto the top of the laminated plywood. The adhesive is then smoothed by the adhesive application roller 6.

[0031] Furthermore, a collection box 8 is fixedly disposed between the two glue-blocking blocks 7. A scraper 9 is disposed on one side of the collection box 8, and one side of the scraper 9 is in contact with the glue-applying roller 6. The inner side of the collection box 8 is inverted trapezoidal. Several glue outlet holes 15 are disposed at the bottom of the collection box 8, and a collection cover 16 is disposed at the bottom of the collection box 8. The collection cover 16 is connected to the inner box of the collection box 8 through several glue outlet holes 15. A glue outlet pipe 17 is connected to one side of the collection cover 16, and the collection cover 16 and the glue outlet pipe 17 are in communication. A second suction assembly is connected to the other side of the glue outlet pipe 17. 18. The second suction component 18 is located on one side of the glue coating box 10 and is connected to the inside of the glue coating box 10. When the glue coating roller 6 rotates, the scraper 9 scrapes off the glue sticking to the glue coating roller 6 and lets it fall into the collection box 8. In this way, scraping off the glue on the outer periphery of the glue coating roller 6 can prevent too much glue on the outer periphery of the glue coating roller 6 from affecting the smoothing effect during continuous glue application and increase the quality of smoothing the glue on the glue coating roller 6. At the same time, the second suction component 18 sucks the glue collected in the collection box 8 into the glue coating box 10 through the glue outlet pipe 17, so that the glue can be reused.

[0032] Furthermore, a filter screen 19 is provided inside the glue outlet pipe 17. During the process of drawing the glue from the collection box 8 to the glue application box 10, the filter screen 19 can filter the sawdust in the glue, preventing sawdust from entering the glue application box 10 and affecting the glue application effect and clogging the nozzle 13. The first suction component 14 and the second suction component 18 are both plunger pumps.

[0033] Furthermore, a second mounting plate 20 is provided on both sides of the base 1, and a horizontal moving device 21 is provided on each of the two second mounting plates 20. A second connecting plate 22 is provided on the driving end of the horizontal moving device 21. Two limiting plates 23 are provided on one side of the second connecting plate 22, and the second mounting frame 4 is located between the two limiting plates 23. The horizontal moving device 21 is a cylinder. Through the horizontal moving device 21, the second connecting plate 22 can be moved during use, so that the second connecting plate 22 drives the limiting plate 23 to move, thereby limiting the conveying and gluing of the laminated plywood on the belt conveyor 2 and preventing the laminated plywood from shifting during the movement.

[0034] Furthermore, the elastic moving assembly includes a plurality of telescopic rods 24 and a plurality of springs 25. The plurality of telescopic rods 24 are disposed on the second mounting frame 4, and the moving ends of the plurality of telescopic rods 24 are connected to the top of the first mounting plate 5. The plurality of springs 25 are sleeved on the outer periphery of the corresponding telescopic rods 24, and the two sides of the springs 25 are respectively connected to the top of the second mounting frame 4 and the top of the first mounting plate 5. Through the provided telescopic rods 24 and springs 25, the film-coated plywood of different thicknesses can pass through the bottom of the coating roller 6 by compressing the springs 25 and the telescopic rods 24.

[0035] Example 2

[0036] The difference between this embodiment and Embodiment 1 is that:

[0037] In this embodiment, a rotary motor 26 is provided on one side of the first mounting plate 5. The drive end of the rotary motor 26 passes through the first mounting plate 5 and is connected to one side of the glue-applying roller 6. The rotary motor 26 drives the glue-applying roller 6 to rotate at high speed, allowing the laminated plywood to quickly pass under the glue-applying roller 6, increasing the efficiency of smoothing the adhesive (e.g., ...).

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
