Description

Technical Field

[0001] This utility model relates to the field of fiberboard technology, specifically a fiberboard production pressing and anti-deformation device. Background Technology

[0002] Fiberboard, also known as MDF, is a type of engineered wood product made from wood fibers or other plant fibers and bonded together with urea-formaldehyde resin or other suitable adhesives. During the production and processing of fiberboard, the raw fiberboard blanks need to be pre-pressed.

[0003] In the prior art, patent announcement number CN222079562U discloses a pre-compression device for fiberboard production, including a worktable. A punching mechanism is installed at the top of the worktable, and four sets of buffer mechanisms are equidistantly arranged at the top of the worktable. A fixing mechanism is symmetrically arranged at the top of the worktable. Each buffer mechanism includes a spring damper and a load-bearing rod, with the spring damper fixedly installed at the top of the worktable.

[0004] In the existing technology, by setting multiple spring damping structures in conjunction with the stamping plate for stamping, the problem of fiberboard deformation due to uneven force during the pressing process can be avoided to a certain extent. However, multiple spring damping structures are prone to failure due to wear and other reasons during long-term use. Since the spring damping structures are fixed, they cannot be disassembled and replaced, which leads to deformation of the fiberboard during subsequent pressing processes, reducing the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a fiberboard production pressing anti-deformation device to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiberboard production pressing and anti-deformation device, comprising a workbench, a stamping structure on the top of the workbench, and disassembly components at the four corners of the top of the workbench. Each disassembly component includes a square groove and a circular groove. The square groove is located on the top of the workbench, and the circular groove is formed on the inner side of the workbench. A square block is located inside the square groove, and a spring damping element is located on the top of the square block. Slots are located on both sides of the square block. An annular plate is rotatably arranged inside the circular groove. A rotating structure is located at the bottom of the annular plate, and an arc-shaped groove is located on the top of the annular plate. Circular blocks are slidably arranged inside both arc-shaped grooves, and insert plates are installed on the tops of both circular blocks. One end of each insert plate is located inside one of the two slots.

[0007] Preferably, the top of the workbench is provided with a stamping groove, the stamping groove is provided with a fixing mechanism, and both sides of the workbench are provided with spare holding structures.

[0008] Preferably, the stamping structure includes a top plate, which is disposed on the top of the workbench. Connecting columns are installed at the four corners of the bottom of the top plate, and the four connecting columns are fixedly connected to the workbench. A mounting plate is provided at the bottom of the top plate, and a stamping plate is installed at the bottom of the mounting plate. Circular holes are opened at the four corners of the top of the mounting plate. The combination of the top plate, connecting columns and mounting plate can ensure the stability of the stamping process.

[0009] Preferably, the stamping structure further includes a hydraulic cylinder and two guide pillars. The hydraulic cylinder is located at the top of the top plate, penetrates the top plate, and is fixedly connected to the top plate. The telescopic end of the hydraulic cylinder is fixedly connected to the mounting plate. The two guide pillars are fixedly connected to the bottom of the top plate, penetrate the mounting plate, and are slidably connected to the mounting plate. The two guide pillars are fixedly connected to the worktable. The guide pillars ensure that the stamping plate remains vertical during its up-and-down movement, avoiding uneven stress on the fiberboard caused by tilting, thereby effectively preventing fiberboard deformation and improving product quality.

[0010] Preferably, the spring damping component includes a spring damping body, which is fixedly connected to the top of the block. A bearing rod is fixedly connected to the top of the spring damping body, and the bearing rod is adapted to the round hole. Through the cooperation of the spring damping body and the bearing rod, the impact force can be more evenly distributed on the entire surface of the fiberboard, further reducing the risk of deformation of the fiberboard during the pressing process.

[0011] Preferably, the rotating structure includes a cylindrical column, which is fixedly connected to the bottom of the annular plate. The bottom end of the cylindrical column is rotatably connected to the worktable. A worm gear is fixedly connected to the outside of the cylindrical column, and a worm is meshed with the outside of the worm gear. One end of the worm is rotatably connected to the worktable, and the other end of the worm passes through the inside of the circular groove and is rotatably connected to the worktable. A throttle handle is installed at the other end of the worm. The way in which both the worm gear and the worm are set inside the circular groove can prevent dust and impurities from falling onto their surface.

[0012] Preferably, one end of each of the two insert plates passes through the inner side of the circular groove and extends into the interior of the square groove, and both insert plates are slidably connected to the worktable.

[0013] Preferably, the spare container structure includes a mounting groove, which is located on the outside of the workbench. A spare box is provided inside the mounting groove. Two placement slots are formed on the top of the spare box. Two L-shaped blocks are fixedly connected to one side of the spare box. Each of the two L-shaped blocks has a rotating block inside, and both rotating blocks are rotatably connected to the workbench.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application uses two circular blocks to move two insert plates out of two slots, thereby releasing the block from its fixation. Then, the operator lifts the spring damping body, causing the block to move upwards along the opening of the square slot, gradually moving away from the slot, and finally completing the disassembly of the spring damping body for replacement. This structural design makes the disassembly process of the spring damping body more convenient, facilitating its maintenance and replacement. It effectively solves the problem that the spring damping structure cannot be disassembled and replaced due to its fixed setting in the prior art, thus improving the practicality of the device.

[0016] 2. This application utilizes two rotating blocks to move them away from the L-shaped block, thereby releasing the spare box from its fixation. The operator can then pull the spare box out of the mounting slot, allowing the spare spring damping component placed in the slot to be removed. This structural design not only facilitates the storage of spare spring damping components but also enables quick removal and replacement when needed, ensuring timely availability of spare components in case of spring damping component failure or replacement.

[0024] 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.

[0025] Example: Figure 1 - Figure 6 As shown, this utility model provides a technical solution for a fiberboard production pressing anti-deformation device, including a workbench 1. A stamping groove 100 is formed on the top of the workbench 1, and a fixing mechanism 101 is installed inside the stamping groove 100. Spare storage structures are provided on both sides of the workbench 1. A stamping structure is provided on the top of the workbench 1, including a top plate 2. The top plate 2 is located on the top of the workbench 1. Connecting columns 3 are installed at the four corners of the bottom of the top plate 2, and all four connecting columns 3 are fixedly connected to the workbench 1. A mounting plate 4 is provided at the bottom of the top plate 2, and a stamping plate 400 is installed at the bottom of the mounting plate 4. Circular holes 440 are formed at the four corners of the top of the mounting plate 4. The stamping structure also includes a hydraulic cylinder 5 and two guide columns 6. The hydraulic cylinder 5 is located on the top of the top plate 2, penetrates the top plate 2, and is fixedly connected to the top plate 2. 5. The telescopic end is fixedly connected to the mounting plate 4. Two guide columns 6 are fixedly connected to the bottom of the top plate 2. Two guide columns 6 penetrate the mounting plate 4 and are slidably connected to the mounting plate 4. Two guide columns 6 are fixedly connected to the workbench 1. The four corners of the top of the workbench 1 are provided with disassembly components. The disassembly components include square grooves 7 and circular grooves 11. Square grooves 7 are opened on the top of the workbench 1. Circular grooves 11 are formed on the inner side of the workbench 1. Square blocks 8 are provided inside square grooves 7. Spring damping components are provided on the top of square blocks 8. Spring damping components include spring damping bodies 9. Spring damping bodies 9 are fixedly connected to the top of square blocks 8. A bearing rod 10 is fixedly connected to the top of spring damping bodies 9. The bearing rod 10 is adapted to the circular hole 440. Slots 800 are opened on both sides of square blocks 8. A ring plate 15 is rotatably arranged inside the circular groove 11.

[0026] The bottom of the annular plate 15 is provided with a rotating structure, which includes a cylindrical column 12. The cylindrical column 12 is fixedly connected to the bottom of the annular plate 15. The bottom end of the cylindrical column 12 is rotatably connected to the worktable 1. A worm gear 13 is fixedly connected to the outside of the cylindrical column 12. A worm 14 is meshed with the outside of the worm gear 13. One end of the worm 14 is rotatably connected to the worktable 1. The other end of the worm 14 passes through the inner side of the circular groove 11 and is rotatably connected to the worktable 1. A handle is installed at the other end of the worm 14. An arc-shaped groove 16 is opened at the top of the annular plate 15. A circular block 17 is slidably arranged inside the two arc-shaped grooves 16. An insert plate 18 is installed at the top of the two circular blocks 17. One end of the two insert plates 18 passes through the inner side of the circular groove 11 and extends into the square groove 7. The two insert plates 18 are slidably connected to the worktable 1. One end of the two insert plates 18 is respectively set inside the two slots 800.

[0027] Specifically, when it is necessary to disassemble block 8, first turn the handle. At this time, the worm 14 meshes with the worm wheel 13. The worm wheel 13 drives the cylindrical column 12 and the annular plate 15 to rotate inside the circular groove 11. Since the top of the annular plate 15 has an arc groove 16, when the annular plate 15 rotates, the two round blocks 17 slide inside the two arc grooves 16. The two round blocks 17 respectively drive the two insert plates 18 to move out of the two slots 800, thereby releasing the block 8 from the fixation. After that, the operator lifts the spring damping body 9, so that the block 8 moves upward along the opening direction of the square groove 7 and gradually moves away from the square groove 7, finally completing the disassembly of the spring damping body 9 so that it can be replaced. This structural design makes the disassembly process of the spring damping body 9 more convenient, and facilitates its maintenance and replacement. It effectively solves the problem that the spring damping structure cannot be disassembled and replaced due to its fixed setting in the prior art, and improves the practicality of the device.

[0028] The fixing mechanism 101 is existing technology and will not be described in detail. This technology has been disclosed in the announcement number CN222079562U, "A pre-compression device for fiberboard production".

[0029] Example: Figure 1 , Figure 3 and Figure 4 As shown, the spare container structure includes a mounting slot 19, which is located on the outside of the workbench 1. A spare box 20 is provided inside the mounting slot 19. Two placement slots 200 are formed on the top of the spare box 20. Two L-shaped blocks 21 are fixedly connected to one side of the spare box 20. Each of the two L-shaped blocks 21 has a rotating block 22 inside. Both rotating blocks 22 are rotatably connected to the workbench 1.

[0030] Specifically, when a spare spring damping component is needed, first rotate the two rotating blocks 22 so that they move away from the L-shaped block 21, thereby releasing the fixation on the spare box 20. Then, the operator can pull the spare box 20 out of the mounting slot 19, and the spare spring damping component placed in the slot 200 can be taken out. This structural design not only facilitates the storage of spare spring damping components, but also makes it easy to quickly take out the spare components for replacement when needed, so as to ensure that spare components can be obtained in a timely manner when the spring damping component fails or needs to be replaced.
