Description

Technical Field

[0001] This utility model relates to the field of laminated board production and processing technology, specifically an automatic glue application device for a laminated board production line. Background Technology

[0002] In the building materials, furniture and packaging industries, laminated boards, with their composite advantages of substrates (such as wood panels and metal panels) and printed films, combine structural strength and aesthetic appeal, resulting in a continuous increase in market demand. Among these factors, the quality of the adhesive coating on the printed film directly determines the bonding stability and surface smoothness of the laminated board, making it a core process in laminated board production.

[0003] Existing adhesive coating equipment mostly adopts a semi-automatic architecture with manual assistance. The feeding and positioning of the printed film, the adjustment of the distance between the glue rollers, and the switching between double-sided adhesive coating all require manual intervention. Specifically, the operator needs to manually fix the printed film roll to the conveying mechanism, and the conveying mechanism will bond the board with the printed film. Only one side can be coated at a time. When coating the other side, the board needs to be flipped over and re-fed and recalibrated before coating the other side, resulting in low production efficiency of coated boards.

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] As attached Figures 1 to 5An automatic gluing device for a laminated board production line is shown, comprising: a frame 1, a frame 11 fixedly installed between the inner walls of opposite sides of the frame 1, a mounting plate 12 and a mounting bracket a13 fixedly installed between the inner walls of opposite sides of the frame 1, the mounting plate 12 being located below the frame 11 and the mounting bracket a13 being located above the frame 11; and a gluing mechanism, which is respectively installed on the mounting plate 12 and the mounting bracket a13, for applying glue to the printed film.

[0026] Among them, the frame 1 is the basic support carrier. Through the layered layout of the frame 11, the mounting plate 12, and the mounting bracket a13, when the laminated board is laminated, the glue application mechanism applies glue to the opposite side of the upper and lower printed films, thereby improving the production efficiency of laminated board lamination.

[0027] The glue application mechanism includes: a lower glue box 2, a top shell 21, a lower glue roller 22, an upper glue roller 23, an upper glue box 24, and a glue dispensing cylinder 25. The lower glue box 2 is fixedly mounted on the top of the mounting plate 12, and the top shell 21 is fixedly mounted on the top of the lower glue box 2. The lower glue roller 22 is rotatably connected between the inner walls of the top shell 21 and its two sides. The upper glue roller 23 is rotatably connected between the inner walls of the mounting frame a13 and its two sides. The upper glue box 24 is fixedly mounted on the top of the mounting frame a13, and the glue dispensing cylinder 25 is fixedly connected to the bottom of the upper glue box 24 for dispensing glue. The bottom end of the cylinder 25 extends through the mounting bracket a13 to the top of the upper glue roller 23. The top of the top shell 21 is trapezoidal in shape. The two opposite sides of the top of the top shell 21 and the opposite sides of the bottom of the glue cylinder 25 are rounded. The lower glue box 2 and the upper glue box 24 are both fixedly connected to one side of the connecting pipe 26. The connecting pipe 26 is fixedly connected to one end of the connecting head 27. The frame 1 has a through groove 28 for the extension of the connecting pipe 26. Liquid level sensors 29 are fixedly installed inside the lower glue box 2 and the upper glue box 24.

[0028] Specifically: When laminating the board, the feeder's conveying pipe is connected to connectors 27 on the lower glue box 2 and the upper glue box 24, respectively. The feeder delivers glue into the lower glue box 2 and the upper glue box 24. The glue level is detected by a level sensor 29. When the glue reaches the set level, the level sensor 29 sends a stop electrical signal to the feeder, causing the feeder to stop delivering glue. When the glue level drops below the set level, the level sensor 29 sends a start electrical signal to the feeder, causing the feeder to start delivering glue. The material feeder starts and conveys glue. When the printing film moves, it drives the upper glue roller 23 and the lower glue roller 22 to rotate. The rotation of the upper glue roller 23 and the lower glue roller 22 carries up the glue inside the lower glue box 2 and the upper glue box 24. The glue is applied to the printing film by the rolling of the upper glue roller 23 and the lower glue roller 22. This allows for double-sided lamination, improving production efficiency. After lamination is completed, the laminating plate is moved out from the frame 1 and cut by the added cutting device. A photoelectric sensor detects whether the laminating plate has moved into place.

[0029] In a preferred embodiment, two feeding rollers 3 are rotatably connected to the inner walls of opposite sides of the frame 11. One end of the rotating shaft of the two feeding rollers 3 extends to the outside and is fixedly mounted with a gear 31. The two gears 31 are meshed together. A drive motor 32 is fixedly mounted on one side of the frame 1. The drive shaft of the drive motor 32 is connected to the rotating shaft of one of the feeding rollers 3.

[0030] Furthermore, after the drive motor 32 starts, it drives the connected feeding roller 3 to rotate. The feeding roller 3 drives the gear 31 at the other end of the rotating shaft to rotate. The two gears 31 mesh with each other, thereby driving the two feeding rollers 3 to rotate relative to each other, thus moving the printing film to one side.

[0031] In a preferred embodiment, a middle plate 33 is fixedly connected between the inner walls of the frame 11 on both sides. A hydraulic push rod a34 is fixedly installed on the top of the middle plate 33. The output end of the hydraulic push rod a34 passes through the middle plate 33 and is fixedly installed with a mounting bracket b35. An upper pressure roller 36 is rotatably connected between the mounting bracket b35 and the inner walls of the frame 11 on both sides. A lower pressure roller 37 is rotatably connected between the inner walls of the frame 11 on both sides at a position relative to the upper pressure roller 36.

[0032] Furthermore, the printing film is adhered to the upper and lower surfaces of the board by the upper pressure roller 36 and the lower pressure roller 37. The length pushed out by the output end of the hydraulic push rod a34 is controlled to drive the mounting frame b35 to move, thereby adjusting the height of the upper pressure roller 36 to adapt to boards of different thicknesses.

[0033] In a preferred embodiment, the frame 11 is provided with two conveyor belts 38, which are located on both sides of the feeding roller 3. The frame 11 is provided with two opposing movable frames 39 on opposite sides. Multiple rollers 310 are rotatably connected inside the movable frames 39. Two hydraulic push rods b311 are fixedly installed on opposite sides of the frame 11. The output end of the hydraulic push rod b311 is connected to the movable frame 39 on the adjacent side.

[0034] Furthermore, the two conveyor belts 38 rotate synchronously, placing the board on the left conveyor belt 38. The board is then moved to the right by the conveyor belt 38, thereby attaching the printing film to the board. The moving frame 39 and the roller 310 provide guidance, allowing the board to move smoothly. The distance between the two moving frames 39 is adjusted by controlling the extension length of the output ends of the hydraulic push rods b311 on both sides.

[0035] In a preferred embodiment, a feeding rack 4 is fixedly installed on the top and bottom of the frame 1, and a feeding roller 41 is rotatably connected between the feeding racks 4. Two pairs of guide rollers 42 are rotatably connected to the inner walls of opposite sides of the frame 1. The two pairs of guide rollers 42 are located on both sides of the lower glue-coating roller 22 and the upper glue-coating roller 23, respectively.

[0036] Furthermore, the printing film roll is installed onto the feeding roller 41, and the feeding roller 41 is installed onto the feeding frame 4. The printing film is then placed between the two feeding rollers 3, passing around the two guide rollers 42 respectively.

[0037] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
