Description

Technical Field

[0001] This utility model relates to the field of fiberboard processing technology, specifically to a fiberboard edge grinding device. Background Technology

[0002] Fiberboard is a type of engineered wood product made by mechanically separating and chemically treating wood or plant fibers, adding adhesives and waterproofing agents, and then molding it under high temperature and pressure. It is an ideal engineered wood product for furniture making. Medium-density fiberboard has a more uniform structure than natural wood, avoiding problems such as rot and insect infestation. It also has low expansion and contraction, making it easy to process. Fiberboard has advantages such as uniform material, small difference in longitudinal and transverse strength, and resistance to cracking, making it widely used.

[0003] In traditional techniques, fiberboard needs to be placed tightly against the worktable surface, with the side to be processed close to the grinding wheel. The operator pushes the fiberboard horizontally so that the grinding wheel can mill the processing area of ​​the fiberboard evenly. However, the worktable surface has no positioning edge. If the operator makes a human error during the grinding process, causing the processing area of ​​the fiberboard to deviate from the grinding wheel, the grinding wheel cannot grind the fiberboard evenly, resulting in an uneven processing area of ​​the fiberboard and affecting the processing quality. At the same time, existing grinding wheels cannot grind fiberboard of various specifications.

[0004] Therefore, it is particularly important to improve existing fiberboard edge grinding devices and design a new type of fiberboard edge grinding device to solve the above-mentioned technical defects and improve the overall practicality of the fiberboard edge grinding device. Utility Model Content

Through the overall design, a reciprocating screw controls the offset of two sets of grinding wheels to grind fiberboards of various specifications. Subsequently, a swing rod presses against the fiberboard to limit its position and prevent offset, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fiberboard edge grinding device includes support feet, two sets of support feet, a stabilizing rod fixedly connected between the two sets of support feet, a first frame and a second frame fixedly connected to the top of the support feet respectively, a conveying roller rotatably connected between the first frame and the second frame, rollers fixedly connected to the outside of the conveying roller, the rollers being evenly distributed, a fixing frame fixedly connected to the inner side wall of the first frame, the end of the fixing frame near the second frame having an open structure design, and guide frames symmetrically fixedly connected to the top and bottom of the inner side of the fixing frame.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] A fiberboard edge grinding device includes two sets of support feet 1, with a stabilizing rod 2 fixedly connected between them. A first frame 3 and a second frame 4 are fixedly connected to the top of each support foot 1. A conveying roller 5 is rotatably connected between the first frame 3 and the second frame 4. Rollers 6 are fixedly connected to the outside of the conveying roller 5, and the rollers 6 are evenly spaced. A fixing frame 7 is fixedly connected to the inner wall of the first frame 3. The end of the fixing frame 7 near the second frame 4 has an open structure design. Guide frames 8 are symmetrically fixedly connected to the top and bottom of the inner side of the fixing frame 7. By placing the support feet 1 in a designated position and the stabilizing rod 2 providing support force, the stability of the support feet 1 is improved. The fiberboard is placed on the surface of the conveying roller 5, and an external power supply is connected to the conveying roller 5. The rollers 6 rotate with the conveying roller 5, lifting the fiberboard so that the side of the fiberboard to be processed enters the interior of the fixing frame 7.

[0028] Furthermore, in this embodiment, a connecting strip 9 is rotatably connected inside the guide frame 8, and a receiving frame 10 is fixedly connected to one end of the connecting strip 9 away from the guide frame 8. By inserting the connecting strip 9 into the interior of the guide frame 8 and moving the receiving frame 10, the connecting strip 9 tilts inside the guide frame 8.

[0029] Furthermore, in this embodiment, a grinding wheel 11 is rotatably connected inside the receiving frame 10, and an auxiliary wheel 12 is fixedly connected to the top of the grinding wheel 11. Friction textures are formed on the surface of the auxiliary wheel 12. When the conveying roller 5 drives the fiberboard to move, the fiberboard rubs against the grinding wheel 11, thereby completing the grinding of one side of the fiberboard. When the connecting strip 9 is tilted, the auxiliary wheel 12 can perform edge grinding treatment on the fiberboard from shallow to deep, which can reduce the impact force on the board during edge grinding, accurately control the thickness of the edge grinding, and reduce the error during edge grinding.

[0030] Furthermore, in this embodiment, a movable block 13 is fixedly connected to the end of the receiving frame 10 away from the connecting strip 9. A limiting groove 14 is opened inside the fixed frame 7, and the movable block 13 extends inside the limiting groove 14. A plug shaft 15 is rotatably connected to the top of the fixed frame 7, and a knob is fixedly connected to the top of the plug shaft 15. The knob has anti-slip texture on its outside. A reciprocating screw 16 is fixedly connected to the bottom of the plug shaft 15, and the reciprocating screw 16 extends to the outside of the movable block 13. The operator holds the knob and drives the plug shaft 15 to rotate, while controlling the reciprocating screw 16 to rotate synchronously. Then, the movable block 13 and the reciprocating screw 16 have a threaded reaction. At the same time, due to the limiting groove 14 limiting it, the two sets of movable blocks 13 move closer to each other, thereby causing one end of the receiving frame 10 to shift.

[0031] Furthermore, in this embodiment, an extension rod is fixedly connected to the bottom of the reciprocating screw 16, and a synchronous wheel 17 is fixedly connected to the bottom of the extension rod. A synchronous belt 18 is meshed with the outside of the synchronous wheel 17. When the reciprocating screw 16 rotates, it drives the synchronous wheel 17 to rotate and mesh with the synchronous belt 18, thereby realizing the synchronous rotation of multiple sets of synchronous wheels 17, and then controlling the synchronous offset of multiple sets of grinding wheels 11 inside the fixed frame 7.

[0032] Furthermore, in this embodiment, a mounting plate 19 is fixedly connected inside the second frame 4, a connecting column is rotatably connected inside the mounting plate 19, a drive rod 20 is fixedly connected to the outside of the connecting column, a linkage rod 21 is rotatably connected to the middle of the top of the mounting plate 19, connecting rods 22 are symmetrically rotatably connected to the top of the mounting plate 19, a swing rod 23 is fixedly connected to the left end of the connecting rod 22, the swing rod 23 extends above the conveyor roller 5, a pressing wheel is rotatably connected to the top of the swing rod 23, and a driven rod is rotatably connected to the right end of the connecting rod 22. 24. The driven rod 24 is rotatably connected to both ends of the linkage rod 21. By rotating the drive rod 20, the drive rod 20 will rotate and squeeze the linkage rod 21, thereby causing the linkage rod 21 to rotate. As the linkage rod 21 rotates, the angle of the linkage rod 21 can be adjusted, thus squeezing the driven rod 24 and causing the swing rod 23 to swing back and forth. By controlling the swing amplitude of the swing rod 23, fiberboards of different widths can be squeezed, so that after being subjected to pressure, they can make stable contact with the grinding wheel 11.

[0033] In this embodiment, the specific implementation scenario is as follows: By placing the support foot 1 in a designated position, and simultaneously providing support force with the stabilizing rod 2 to enhance the stability of the support foot 1, the fiberboard is placed on the surface of the conveyor roller 5, and an external power supply is connected to the conveyor roller 5. The roller 6 rotates with the conveyor roller 5, simultaneously lifting the fiberboard so that the side of the fiberboard to be processed enters the interior of the fixed frame 7. The operator holds the knob and drives the insertion shaft 15 to rotate, while simultaneously controlling the reciprocating screw 16 to rotate synchronously. Then, the moving block 13 and the reciprocating screw 16 undergo a threaded reaction. At the same time, due to the limiting groove 14 limiting it, the two sets of moving blocks 13 move closer to each other, thereby causing one end of the receiving frame 10 to shift. After the connecting strip 9 tilts, the auxiliary wheel 12 can perform edge grinding on the fiberboard from shallow to deep. The mechanism reduces the impact force on the board during edge grinding, accurately controls the edge thickness, and minimizes the error during corner grinding. When the reciprocating screw 16 rotates, it drives the synchronous wheel 17 to rotate and mesh with the synchronous belt 18, enabling multiple sets of synchronous wheels 17 to rotate synchronously. This, in turn, controls the synchronous offset of multiple sets of grinding wheels 11 inside the fixed frame 7. By rotating the drive rod 20, the drive rod 20 will rotate and press the linkage rod 21, causing the linkage rod 21 to rotate. As the linkage rod 21 rotates, its angle can be adjusted, thus pressing the driven rod 24 and causing the swing rod 23 to swing back and forth. By controlling the swing amplitude of the swing rod 23, it is possible to press fiberboards of different widths, ensuring that they are under pressure and make stable contact with the grinding wheels 11.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
