Description

Technical Field

[0001] This utility model relates to the field of foam board processing technology, specifically a pressing device for foam board bonding processing. Background Technology

[0002] Foam board, as a lightweight, heat-insulating, and shock-resistant material, is widely used in furniture manufacturing, building decoration, packaging, and transportation. In actual production, the bonding of foam boards is one of the core processes. It typically involves bonding two or more foam boards with adhesive and applying pressure to form a composite structure or specific shape. Traditional foam board bonding equipment mainly consists of a pressure plate mechanism, a drive unit, and an operating platform. Its working principle involves stacking adhesive-coated foam boards under a pressure plate, and then applying vertical pressure to the foam boards through mechanical or hydraulic drive to achieve bonding and curing.

[0003] In existing equipment, if operators fail to adequately control the amount or uniformity of adhesive application during the bonding process, the two foam boards are prone to relative slippage or misalignment due to localized differences in adhesive flow during pressure application. Furthermore, the existing pressing platforms are mostly fixed planar structures, while foam boards, with their rough surfaces and soft textures, experience significant frictional resistance when in contact with platforms made of metal or composite materials. When bonding large-sized or multi-layered foam boards, operators must frequently push and remove the boards, but the planar platforms lack auxiliary moving mechanisms, leading to manual dragging or handling for loading and unloading. This increases labor intensity, especially in continuous production scenarios, and can easily cause operator fatigue. Additionally, the sliding friction between the foam board and the platform can damage the board surface and even cause premature adhesive peeling.

[0004] Based on this, a laminating device for foam board bonding processing is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-7 As shown, a foam board bonding and laminating device includes a pressure plate 11 and an operating table 14. The pressure plate 11 is fixedly connected to the output ends of two electric cylinders 12. The electric cylinders 12 are fixedly mounted on the upper end of a ceiling panel 13. The ceiling panel 13 is fixedly mounted on the upper end of the operating table 14. A base frame 15 is fixedly mounted on the bottom end of the operating table 14. First positioning rods 16 are symmetrically slidably mounted on the upper end of the operating table 14. A second positioning rod 17 is provided between the two first positioning rods 16. The second positioning rod 17 is located at the end positions of the two first positioning rods 16. The upper ends of the positioning rods 17 are symmetrically provided with mounting grooves, and guide rods 18 are fixedly provided in the mounting grooves. The guide rods 18 are provided with adjustment components for adjusting the limiting size. The upper end of the operating table 14 is symmetrically provided with sliding grooves, and the sliding grooves are provided with conveying mechanisms to facilitate the feeding of foam boards. The other end between the two first positioning rods 16 is provided with a limiting mechanism to finally fix the foam board. The conveying mechanism helps to reduce the friction between the bottom end of the foam board and the upper end of the operating table 14. The limiting mechanism facilitates the final fixing of the foam board and the feeding and unloading of the foam board.

[0028] The adjustment assembly includes a first sliding rod 19. Each of the guide groove rods 18 has a sliding rod 19 slidably mounted inside. The bottom end of each first sliding rod 19 has a sliding groove. Each sliding groove contains a first guide rod 21 slidably mounted inside the sliding groove. The first guide rod 21 is fixedly mounted inside the bottom end of the guide groove rod 18. One end of each first guide rod 21 is fixedly mounted with a limiting plate. A limiting groove is provided in the sliding groove corresponding to the position of the limiting plate. A first return spring 20 is provided between the bottom end of the guide groove rod 18 and one end of each first sliding rod 19. Each guide groove rod 18 has a symmetrically mounted fixing plate. Each fixing plate has a second guide rod slidably mounted on it. The second guide rods are fixedly mounted at the bottom end of the operating table 14. A connecting plate is provided between two fixing plates on the same side. The connecting plate contains... The operating table 14 has threaded holes, each fitted with an adjusting screw 22. Each adjusting screw 22 has a first rotating plate at both ends, which are fixed to the bottom of the operating table 14. Each adjusting screw 22 has a handwheel at one end. The operating table 14 has an adjusting groove at a position corresponding to the guide rod 18. In use, when adjusting the distance between the two first positioning rods 16, rotating the adjusting screw 22 at the corresponding position of the first positioning rod 16 causes the adjusting screw 22 to move the guide rod 18 under the action of the thread. The guide rod 18 slides within the adjusting groove and moves the first positioning rod 16, thereby adjusting the distance between the two first positioning rods 16. Similarly, the position of the second positioning rod 17 can be adjusted.

[0029] The limiting mechanism includes a third positioning rod 23, which is disposed in a storage groove at the upper end of the operating table 14. The two ends of the third positioning rod 23 have rotating shafts rotatably disposed in rotating holes on one side of the storage groove. One end of the rotating shaft of the third positioning rod 23 is fixedly connected to the output end of a motor 24, which is fixedly disposed on one side of the operating table 14. The upper end of the third positioning rod 23 has symmetrically provided mounting grooves. Each mounting groove has a symmetrically provided guide slot frame 25 at its upper end. A second sliding rod 26 is slidably disposed between the two guide slot frames 25. A fixed sliding plate is fixedly disposed at one end of each of the second sliding rods 26. Third guide sliding rods are slidably disposed at both ends of each fixed plate. The third guide sliding rods are fixedly disposed in the mounting grooves. The bottom end of each fixed sliding plate is fixedly connected to one end of two second return springs 27. Next, the other end of the second return spring 27 is fixedly connected to the bottom of the mounting groove. In use, when the foam board is placed on the upper end of the operating table 14 and located between the first positioning rod 16 and the second positioning rod 17, the motor 24 is started. The output end of the motor 24 drives the third positioning rod 23 to rotate 90 degrees, so that one side of the third positioning rod 23 is in close contact with one end of the foam board. At the same time, the first sliding rod 19 and the second sliding rod 26 are both in close contact with the foam board. Then, the electric cylinder 12 is started. The output end of the electric cylinder 12 drives the pressure plate 11 to move. The pressure plate 11 presses the foam board. During the movement of the pressure plate 11, the pressure plate 11 can squeeze the first sliding rod 19 and the second sliding rod 26, so that the first sliding rod 19 and the second sliding rod 26 slide respectively, thereby satisfying the positioning and fixing of different foam boards.

[0030] The conveying mechanism includes two conveyor belts 28 arranged symmetrically. The conveyor belts 28 are disposed inside sliding boxes 29. The two sliding boxes 29 are respectively slidably disposed in two sliding grooves at the upper end of the operating platform 14. Both ends of the sliding boxes 29 are equipped with transmission rollers, which are rotatably disposed inside the sliding boxes 29. Fixed boxes 30 are fixedly disposed at the bottom end of the operating platform 14 and at the sliding groove. Both ends of the sliding boxes 29 are hinged with connecting rods 31. The other end of the connecting rods 31 on the same side is hinged to an adjusting block 32. The two adjusting blocks 32 are arranged symmetrically. The adjusting blocks 32 are slidably disposed on two fourth guide slide rods. The fourth guide slide rods are fixedly disposed inside the fixed boxes 30. The fixed boxes 30 are provided with a linkage component for driving the conveyor belts 28 to rise and fall.

[0031] The linkage assembly includes a bidirectional screw 33, with second rotating plates rotatably mounted at both ends of the bidirectional screw 33. The second rotating plates are fixedly mounted at the bottom of the fixed housing 30. Two adjusting blocks 32 are fitted onto the bidirectional screw 33. An extension shaft is fixedly mounted at one end of the bidirectional screw 33, and a first bevel gear is fixedly mounted at one end of the extension shaft. A second bevel gear meshes with the first bevel gear. The second bevel gear is fixedly mounted at one end of a transmission shaft 34, which rotatably resides in a mounting hole at the bottom of the storage slot. A third bevel gear is fixedly mounted at the other end of the transmission shaft 34, and a bevel gear ring 35 meshes with the third bevel gear. The bevel gear ring 35 is fixedly mounted on a third positioning rod 23. In use, when it is necessary to press and feed the foam board, the motor 24 drives the third positioning rod. Rotation of position 23 causes the third positioning rod 23 to retract into the receiving slot. During the rotation of position 23, position 23 drives the bevel gear ring 35 to rotate. The bevel gear ring 35 meshes with the third bevel gear, driving the transmission shaft 34 to rotate. The transmission shaft 34 meshes with the first bevel gear through the second bevel gear, driving the bidirectional screw 33 to rotate. Under the action of the screw, the bidirectional screw 33 drives the two adjusting blocks 32 to move in opposite directions. The adjusting blocks 32 push the sliding box 29 to slide through the connecting rod 31, thereby making the upper end of the conveyor belt 28 higher than the upper end of the operating table 14, which facilitates the feeding and unloading of foam boards. When pressing the foam board, position 23 rotates and is in close contact with the foam board, causing the conveyor belt 28 to descend, and the upper end of the conveyor belt 28 is on the same plane as the upper end of the operating table 14.

[0032] The sliding box 29 is equipped with a plurality of auxiliary rollers 37 arranged inside. The auxiliary rollers 37 are all in close contact with the upper end of the conveyor belt 28. The auxiliary rollers 37 are rotatably arranged inside the sliding box 29, which facilitates the auxiliary support of the conveyor belt 28 during use.

[0033] One side of the first sliding rod 19 is on the same plane as the opening side of the guide groove rod 18. The opening side of the guide groove rod 18 is on the same plane as one side of the first positioning rod 16 and the second positioning rod 17. The guide groove frame 25 and the second sliding rod 26 are on the same plane as both sides of the third positioning rod 23. In use, this facilitates precise positioning of the foam board and prevents the foam board from shifting.

[0034] Each of the first positioning rod 16 and the third positioning rod 23 is fixedly provided with a guide plate 36. One end of the guide plate 36 is inclined, which facilitates the guiding and positioning of the foam board when feeding it.

[0035] The above embodiment discloses a laminating device for foam board bonding processing. When the foam board needs to be laminating and fed, the motor 24 drives the third positioning rod 23 to rotate, causing the third positioning rod 23 to be retracted into the receiving groove. During the rotation of the third positioning rod 23, the third positioning rod 23 drives the bevel gear ring 35 to rotate. The bevel gear ring 35 meshes with the third bevel gear, driving the transmission shaft 34 to rotate. The transmission shaft 34, through the meshing of the second bevel gear and the first bevel gear, drives the bidirectional screw 33 to rotate. Under the action of the screw thread, the bidirectional screw 33 drives two adjusting blocks 32 to move in opposite directions. The adjusting blocks 32 push the sliding box 29 to slide through the connecting rod 31, thereby making the upper end of the conveyor belt 28 higher than the upper end of the operating table 14, so that one end of the foam board is tightly attached to the upper end of the conveyor belt 28. Subsequently, pushing the foam board causes the conveyor belt 28 to rotate, thereby reducing the foam... The foam board rubs against the upper end of the operating table 14, while the foam board is located between the two first positioning rods 16 and is in close contact with one side of the first positioning rod 16. When one end of the foam board is in close contact with the second positioning rod 17, the pushing of the foam board stops, and then the motor 24 is started. The output end of the motor 24 drives the third positioning rod 23 to rotate 90 degrees, so that one side of the third positioning rod 23 is in close contact with one end of the foam board. At the same time, the bidirectional screw 33 rotates in the opposite direction, so that the upper end of the conveyor belt 28 is on the same plane as the upper end of the operating table 14. The electric cylinder 12 is started, and the output end of the electric cylinder 12 drives the pressure plate 11 to move. The pressure plate 11 presses the foam board. During the movement of the pressure plate 11, the pressure plate 11 can squeeze the first sliding rod 19 and the second sliding rod 26, so that the first sliding rod 19 and the second sliding rod 26 slide respectively, thereby satisfying the positioning and fixing of different foam boards.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
