Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a wood polishing and chamfering device. Background Technology

[0002] In the wood processing industry, polishing and chamfering of wood panels are key processes for improving their quality and appearance. Traditional wood panel polishing and chamfering operations usually rely on manual labor using simple tools or single-function equipment. Manual operation is not only labor-intensive and inefficient, but it is also difficult to guarantee the consistency and stability of processing quality. The polishing effect and chamfering accuracy are greatly affected by the skill level of the operator.

[0003] Existing automated processing equipment often has limited functionality. Polishing equipment typically only performs a single level of polishing, failing to meet the multi-level polishing requirements for high-quality wood surface finishes. Beveling equipment, on the other hand, struggles to adapt flexibly to beveling wood boards of different sizes, resulting in cumbersome adjustment processes. Furthermore, the lack of effective guiding and positioning mechanisms when the wood boards enter the processing equipment can easily lead to board misalignment during processing, affecting processing accuracy.

[0004] Therefore, it is necessary to provide a new wood panel polishing and chamfering device to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1-5 ,in, Figure 1A three-dimensional structural diagram of the wood polishing and chamfering device provided by this utility model; Figure 2 A three-dimensional structural diagram of the wood polishing and chamfering device provided by this utility model; Figure 3 A schematic diagram of the chamfering mechanism provided by this utility model; Figure 4 A partial structural diagram of the polishing mechanism provided by this utility model; Figure 5 A schematic diagram of the guiding mechanism provided by this utility model.

[0022] In the specific implementation process, such as Figures 1-5 As shown, a wood polishing and chamfering device includes a worktable 1, a support frame 2, a polishing mechanism, a chamfering mechanism, and a guide mechanism. The support frame 2 is fixedly mounted on the top of the worktable 1. The polishing mechanism is mounted on the support frame 2, the chamfering mechanism is mounted on one side of the polishing mechanism, and guide mechanisms are provided on both the left and right sides of the worktable 1.

[0023] The polishing mechanism includes a cylinder 3, a first guide rod 4, a U-shaped frame 5, a first polishing roller 6, a second polishing roller 7, a third polishing roller 8, a transmission assembly, and a first motor 9.

[0024] A cylinder 3 is fixedly installed on the support frame 2 by bolts. The piston rod of the cylinder 3 is fixedly connected to the U-shaped frame 5. A first guide rod 4 is fixedly connected to the top of the U-shaped frame 5. The first guide rod 4 is slidably connected to the guide hole preset on the support frame 2 to ensure that the U-shaped frame 5 can move up and down stably under the drive of the cylinder 3.

[0025] The first polishing roller 6, the second polishing roller 7, and the third polishing roller 8 are rotatably connected to the U-shaped frame 5 via bearings, and the three polishing rollers are arranged horizontally. The first motor 9 is also fixedly installed on the U-shaped frame 5 by bolts, and the output shaft of the first motor 9 is fixedly connected to one end of the first polishing roller 6 via a coupling.

[0026] The transmission assembly includes a first large sprocket 10, a second large sprocket 11, a first small sprocket 12, a second small sprocket 13, a first chain 14, and a second chain 15. The first polishing roller 6, at its end furthest from the first motor 9, is fixedly connected to the first large sprocket 10 via a key. The second polishing roller 7, at one end, is fixedly connected to the first small sprocket 12 and the second large sprocket 11 via a key. The first large sprocket 10 and the first small sprocket 12 are connected via the first chain 14. The third polishing roller 8, at one end, is fixedly connected to the second small sprocket 13 via a key. The second large sprocket 11 and the second small sprocket 13 are connected via the second chain 15. When the first motor 9 starts, it drives the first polishing roller 6 to rotate. The first polishing roller 6 drives the first large sprocket 10 to rotate. The first large sprocket 10 drives the first small sprocket 12, the second large sprocket 11 and the second polishing roller 7 to rotate through the first chain 14. Since the diameter of the first large sprocket 10 is larger than that of the first small sprocket 12, the rotational speed of the second polishing roller 7 is higher than that of the first polishing roller 6. The second large sprocket 11 drives the second small sprocket 13 and the third polishing roller 8 to rotate through the second chain 15. Since the diameter of the second large sprocket 11 is larger than that of the second small sprocket 13, the rotational speed of the third polishing roller 8 is higher than that of the second polishing roller 7, thereby realizing the three-stage polishing operation of the wood board.

[0027] The chamfering mechanism includes a fixed frame 16, a second motor 17, a first lead screw 18, a second guide rod 19, a first slider 20, a third motor 22, and a chamfering head 21.

[0028] A fixed frame 16 is bolted to the U-shaped frame 5. A first lead screw 18 is rotatably connected to the fixed frame 16 via bearings. A second motor 17 is also bolted to the fixed frame 16, and the output shaft of the second motor 17 is fixedly connected to one end of the first lead screw 18 via a coupling. The threads at both ends of the first lead screw 18 have opposite directions, and two symmetrically arranged first sliders 20 are threaded to both ends of the first lead screw 18. Two symmetrically arranged second guide rods 19 are fixedly connected to the fixed frame 16. The second guide rods 19 are slidably connected to the pre-set guide holes on the first sliders 20, ensuring that the first sliders 20 can slide stably along the second guide rods 19.

[0029] Two first sliders 20 are bolted to the bottom of a third motor 22, and chamfering heads 21 are keyed to the output shafts of the two third motors 22. When chamfering is required on the wood board, the second motor 17 is started, driving the first lead screw 18 to rotate. Since the threads at both ends of the first lead screw 18 rotate in opposite directions, the two first sliders 20 will move simultaneously to the center or sides, thereby adjusting the distance between the two chamfering heads 21 to accommodate the chamfering requirements of wood boards of different sizes. Then, the third motor 22 is started, driving the chamfering heads 21 to rotate, thus completing the chamfering process on the wood board.

[0030] The guiding mechanism includes a mounting groove 23, a fourth motor 24, a second lead screw 25, a third guide rod 26, a second slider 27, and a guide roller 28.

[0031] Two symmetrically arranged mounting slots 23 are provided on the top of the worktable 1. A second lead screw 25 is rotatably connected to the mounting slots 23 via bearings. A fourth motor 24 is bolted to the worktable 1. The output shaft of the fourth motor 24 is fixedly connected to one end of the second lead screw 25 via a coupling. The threads at both ends of the second lead screw 25 have opposite directions, and two symmetrically arranged second sliders 27 are threadedly connected to both ends of the second lead screw 25. Two symmetrically arranged third guide rods 26 are fixedly connected to the mounting slots 23. The second sliders 27 are slidably connected to the pre-set guide holes on the third guide rods 26 to ensure that the second sliders 27 can slide stably along the third guide rods 26.

[0032] Two symmetrically arranged guide rollers 28 are rotatably connected to the top of the two second sliders 27 via bearings. Before the wooden board enters the device for polishing and chamfering, the fourth motor 24 is started, driving the second lead screw 25 to rotate. Since the threads at both ends of the second lead screw 25 rotate in opposite directions, the two second sliders 27 will move simultaneously to the middle or sides, thereby adjusting the distance between the two guide rollers 28, so that the wooden board can accurately enter the polishing and chamfering area, playing a guiding and positioning role.

[0033] The top of the workbench 1 has a strip-shaped through hole 29, and several evenly distributed rotating rollers 30 are rotatably connected to the strip-shaped through hole 29 via bearings. The rotating rollers 30 facilitate the movement of the wooden board on the workbench 1, reduce the friction between the wooden board and the workbench 1, and make the conveying of the wooden board smoother.

[0034] The working principle of the wood polishing and chamfering device provided by this utility model is as follows: First, according to the size of the wood board, the distance between the two guide rollers 28 is adjusted by the fourth motor 24 of the guide mechanism to allow the wood board to enter the device smoothly. Then, the cylinder 3 is started to adjust the polishing mechanism to a suitable height. Next, the first motor 9 is started to drive the three polishing rollers to rotate for three-stage polishing, and at the same time, the second motor 17 is started to adjust the distance between the two chamfering heads 21 according to the chamfering requirements of the wood board. After that, the wood board is placed on the rotating roller 30 and pushed into the device. Under the guidance of the guide rollers 28, the wood board passes through the polishing mechanism and the chamfering mechanism in sequence to complete the polishing and chamfering process.

[0035] The circuits and controls involved in this utility model are all existing technologies, such as the control methods for starting, stopping and speed regulation of motors, which will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
