Technical Field

[0001] The utility model relates to the technical field of multi-layer board production, in particular to a multi-layer board laminating device convenient for gluing. Background Art

[0002] A multi-layer board, also known as plywood, is a kind of artificial board, which is widely used in furniture manufacturing, building decoration, musical instrument making, packaging and other fields. In the production process, usually a layer board coated with glue and an uncoated layer board are stacked together, and the glue is cured by heating and pressing, so as to bond the multi-layer boards into a whole. Such a production method can improve the utilization rate of wood, reduce waste, and the obtained multi-layer board has better stability and strength.

[0003] At present, when processing multi-layer boards, generally after the glue-coated board and the dry board to be processed are all preliminarily laminated, they are uniformly pressed. In this way, the air bubbles in the glue layer cannot be discharged in time and effectively, and air bubble residues are likely to be formed in the multi-layer board. Moreover, when uniformly pressing after all laminations, the alignment between some board layers may be inaccurate, affecting the processing quality of the multi-layer board. Content of the Utility Model

The two feeding mechanisms are respectively used for conveying the glue board and the dry board, and photoelectric sensors for detecting the discharge of the boards are arranged at the output ends of the two feeding mechanisms. An installation frame is connected between the two feeding mechanisms. The pressing mechanism is arranged below the installation frame and is used for applying pressure to the glue board and the dry board for lamination. The controller is used for controlling the pressing mechanism to move downward to press the boards after receiving the signals of the two photoelectric sensors.

[0006] Preferably, the pressing mechanism includes a first telescopic member arranged on the installation frame, a connecting plate connected to the movable end of the first telescopic member, and a swing arm hinged to the bottom end of the connecting plate.

[0022] The following will be combined with the attached Figures 1 to 6 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] If Figures 1-6 As shown, the utility model provides a multi-layer board laminating device that is easy to apply glue through improvement, including two feeding mechanisms 1 and a pressing mechanism for applying pressure to the glue plate and the dry plate for laminating, a mounting frame 4 is connected between the feeding mechanisms 1, and the pressing mechanism is arranged below the mounting frame 4, the feeding mechanism 1 includes a plurality of conveying rollers 12 installed on a conveying platform 11 and two upper and lower rotating rollers 13, the plate passes through the conveying rollers 12 between the two rotating rollers 13 for feeding, and the output directions of the two feeding mechanisms 1 are opposite, and a gluing mechanism 2 is arranged at the upper end of one of the feeding mechanisms 1, and the gluing mechanism 2 is respectively provided with a container for containing glue liquid above and below the two rotating rollers 13 The glue tank, etc., is used to convey glue liquid to the two rollers 13 so that both sides of the plate are coated with glue. This technology is prior art and should be known to those skilled in the art. No further elaboration is given here. The two feeding mechanisms 1 are used to convey the glue plate and the dry plate respectively. They also include photoelectric sensors 3 at the output ends of the two feeding mechanisms 1 and a controller 5 electrically connected to the photoelectric sensors 3. When the plate coated with glue and the plate not coated with glue are output from the feeding mechanism 1, the photoelectric sensor 3 detects the discharge of the plate and transmits a signal to the controller 5. When the controller 5 receives the signals from the two photoelectric sensors 3, it can control the movement of the pressing mechanism to apply pressure to the plate to make it fit.

[0024] Specifically, when in use, the dry plate and the glue plate are first outputted by the feeding mechanism 1, and then the plates are preliminarily aligned manually. After that, the controller 5 receives the signals from the two photoelectric sensors 3 and controls the pressing mechanism to move downward to preliminarily press the two plates, so that the bubbles between the two adjacent plates are squeezed out and the glue is better distributed and solidified.

[0025] Among them, as Figure 1 shown, prompt members 51 are provided on both of the two feeding mechanisms 1, and the prompt members 51 are electrically connected to the controller 5. The prompt members 51 can be warning lights, displays, etc. After a certain feeding mechanism 1 completes one conveyance of the board, the prompt member 51 can issue a prompt to notify the operator that this feeding mechanism 1 has conveyed the board once, which can avoid the situation where two adjacent glue boards or adjacent dry boards appear in the same multi-layer board.

[0026] Furthermore, as Figure 4 well as Figure 5 shown, the pressing mechanism includes a first telescopic member 6 provided on the mounting frame 4, a connecting plate 61 connected to the movable end of the first telescopic member 6, and a swing arm 62 hinged to the bottom end of the connecting plate 61. The other end of the swing arm 62 is rotatably connected to a pressing roller 63. When the first telescopic member 6 moves downward, it drives the connecting plate 61 and the swing arm 62 to move downward. When the pressing roller 63 touches the board, a certain pressure is generated on the surface of the board by the pressing roller 63, and the two swing arms 62 swing in opposite directions around the hinge point to complete a preliminary pressing of the board. After the first telescopic member 6 drives the connecting plate 61 to move upward, after the pressing roller 63 disengages from the board, under the action of the self-gravity of the swing arm 62 and the pressing roller 63, it will automatically reset, making the two swing arms 62 in a vertical and parallel state, waiting for the next pressing operation.

[0027] Furthermore, as Figure 3 shown, in order to avoid a pressing dead angle between the two pressing rollers 63, the pressing mechanism further includes a second telescopic member 7 installed on the mounting frame 4. The movable end of the second telescopic member 7 is connected to a pressing seat 71. The pressing seat 71 is located between the two pressing rollers 63. When the second telescopic member 7 drives the pressing seat 71 to move downward, the bottom of the pressing seat 71 will press on the board, and then the first telescopic member 6 drives the pressing roller 63 to press the board. Arc-shaped guiding parts 72 are provided on both sides of the pressing seat 71, and the two arc-shaped guiding parts 72 are arranged in an "eight" shape. The two pressing rollers 63 are respectively located in the two arc-shaped guiding parts 72. When the first telescopic member 6 drives it to move downward, the pressing roller 63 will swing along the arc-shaped guiding part 72 to one side. When the pressing roller 63 resets, when the pressing roller 63 touches the arc-shaped guiding part 72, it will also limit the position of the pressing roller 63 to prevent the two pressing rollers 63 from swinging in opposite directions.

[0028] Furthermore, as Figure 3 shown, a third telescopic member 8 is provided on the mounting frame 4. The movable end of the third telescopic member 8 is connected to a flat pressing plate 81. When cold pressing is required to cure the glue after a part of the board is initially bonded, the third telescopic member 8 drives the flat pressing plate 81 to move downward so that the flat pressing plate 81 and the bottom of the pressing seat 71 are on the same horizontal plane, thereby realizing a comprehensive pressing of the board.

[0029] Among them, the first telescopic member 6, the second telescopic member 7 and the third telescopic member 8 can all be hydraulic telescopic rods, hydraulic push rods and other devices that can achieve reciprocating linear motion and have a certain force.

[0030] Furthermore, such as Figure 1 As shown in the figure, a receiving seat 9 for receiving the plates is provided below the mounting frame 4. The plates outputted from the two feeding mechanisms 1 can fall on the receiving seat 9. After preliminary manual alignment, the pressing process can be carried out. A marking rod 91 is provided on the receiving seat 9. The height of the marking rod 91 is less than the height of the feeding mechanism 1. As the number of plates increases, the stacking height of the plates on the receiving seat 9 also increases. The stacking height of the plates can be observed through the marking rod 91. If the stacking height of the plates is higher than the marking rod 91, when the plates are transported again by the two feeding mechanisms 1, the plates may not fall directly on top of the stacked plates, and may even conflict with the side walls of the stacked plates, affecting the feeding effect. Therefore, the stacking height of the plates is referenced by the marking rod 91, and then the feeding of the feeding mechanism 1 is stopped. The plates are fully pressed by the flat pressing plate 81 and the pressing seat 71 to achieve a better fitting effect.

[0031] The above description of the disclosed embodiments enables professionals in the field to implement or use the utility model. Various modifications to these embodiments will be apparent to professionals in the field, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.​​
