Technical Field
[0001] The utility model relates to the technical field of wood board processing, and particularly relates to a device for grinding the rough edges of wood boards. Background Art
[0002] In the production and manufacturing process of furniture, wood boards are common raw materials; the processing of wood boards is to cut, process and treat the original wood, so as to facilitate the application in the manufacturing process of furniture with different shapes. Among them, after the wood board is cut, burrs, flash edges, etc. are likely to appear on the cutting edge, which not only affects the processes such as handling, edge sealing, and assembly, but also easily affects the aesthetics of the finally formed furniture; therefore, after the wood board is cut, it is usually necessary to grind its side edges to reduce the influence of burrs and flash edges. Chinese patent document CN220074212U discloses an auxiliary tooling for a wood board edge grinding machine, which sets a fixing plate and a bottom support, a guiding edge protrudes on the fixing plate, a step is provided on the bottom support, and a clamping device is set. The quality of the tooling is relatively large, which can effectively increase the center of gravity of the wood board to be processed and improve the stability during the grinding process of the wood board; in addition, the contact area between the bottom support and the fixing plate is large, and there is a guiding edge for guiding, so that the problem of unstable wood board will not occur during the grinding process. However, this auxiliary tooling can only perform single-side grinding of the wood board at a time, with low grinding efficiency and cumbersome operation, seriously wasting the time for batch production of wood boards. Summary of the Utility Model
[0003] Aiming at the problems existing in the above prior art, the purpose of the utility model is to provide a device for grinding the rough edges of wood boards, which can not only grind the two side edges of the wood board simultaneously to improve the grinding efficiency, but also effectively clamp and position the wood board during the grinding process to avoid its shaking due to the rotation of the grinding column and affecting the grinding quality.
[0004] The purpose of the utility model is realized through the following technical solutions:
[0005] A device for grinding the rough edges of wood boards includes a workbench, a portal bracket, a lifting mechanism, an adjusting seat, a conical slider, a clamping mechanism and a grinding mechanism. A protruding placing table is arranged in the middle of the workbench, and sliding guide rails are symmetrically arranged on both sides of the placing table. The bottom ends of the two legs of the portal bracket are respectively slidably connected to the corresponding sliding guide rails, and the bottom surface of the cross beam of the portal bracket is provided with an adjusting seat through the lifting mechanism. The adjusting seat is slidably arranged between the two legs of the portal bracket.

[0007] Based on further optimization of the above scheme, the lifting mechanism consists of no less than two telescopic rods, which can be either hydraulic or electric.
[0008] Based on the further optimization of the above scheme, lifting sliders are respectively provided on the upper side of the outer wall of the adjustment seat and on the two legs of the portal frame. Vertical sliding grooves are opened on the inner walls of the two legs of the portal frame, and the lifting sliders are slidably engaged in the corresponding vertical sliding grooves.
[0009] Based on further optimization of the above scheme, the clamping mechanism includes a sliding column, a pressing plate, a return spring and a rolling assembly. The top of the sliding column is fixedly connected to the bottom surface of the conical slider, and its bottom end passes through the corresponding bottom surface of the adjusting seat and is fixedly connected to the end face of the pressing plate located on the lower side of the adjusting seat. A return spring is set between the end face of the pressing plate and the bottom surface of the adjusting seat and located on the outer ring of the sliding column. A rolling assembly is set on the bottom surface of the pressing plate.
[0010] Based on further optimization of the above scheme, the length of the extrusion plate is no greater than the width of the protrusion of the adjustment seat.
[0011] Based on further optimization of the above scheme, the grinding mechanism includes a connecting block, a grinding bracket, a connecting rod, and a grinding column. The connecting block is slidably disposed on the bottom surface of the adjusting seat located on both sides of the protrusion, and the grinding bracket is fixedly disposed on the bottom of the connecting block. The connecting rod is fixedly disposed on the side of the grinding bracket near the conical slider, and the end of the connecting rod away from the grinding bracket passes through the corresponding side wall of the protrusion of the adjusting seat and is slidably engaged in the inclined surface of the conical slider.

[0013] The following are the technical effects of this utility model:
[0014] This application achieves initial positioning of the wooden board by adjusting the downward movement of the adjusting seat and using the clamping mechanism to press the board placed on the end face of the placement table, thus avoiding the problem of the board jumping due to friction during the sanding process. As the adjusting seat continues to move downward and is supported by the board and the placement table clamping mechanism (mainly the pressing plate and the rolling assembly), the conical slider moves upward relative to the cavity. The conical slider pulls the sanding mechanisms on both sides toward each other, achieving side clamping and positioning of the board on the placement table by the two sanding mechanisms. This can also be adjusted according to the different widths of the board to be processed. Then, the two sanding components, in conjunction with the sliding of the gantry bracket, simultaneously sand the two sides of the board, effectively improving sanding efficiency and saving sanding time.

[0021] A wood board rough edge sanding device includes a worktable 10, a gantry-shaped support 20, a lifting mechanism, an adjusting seat 40, a conical slider 50, a clamping mechanism, and a sanding mechanism. A protruding placement platform 11 is provided in the center of the worktable 10, and sliding guide rails 12 are symmetrically arranged on both sides of the placement platform 11 (e.g., ...). Figure 1As shown). The bottom ends of the two legs of the portal bracket 20 are respectively slidably connected to the corresponding side sliding guide rails 12. Specifically: sliding seats 21 are fixedly arranged at the bottom ends of the two legs of the portal bracket 20, and the bottom surface of the sliding seat 21 is slidably clamped on the corresponding sliding guide rail 12, so as to realize the sliding connection between the portal bracket 20 and the corresponding sliding guide rail 12 (as Figure 1 As shown). An adjusting seat 40 is arranged on the bottom surface of the cross beam of the portal bracket 20 through a lifting mechanism. The lifting mechanism is composed of not less than two telescopic rods 30. The telescopic rods 30 can adopt any one of hydraulic telescopic rods or electric telescopic rods (as Figure 1 As shown, in this embodiment, two telescopic rods 30 are adopted and they are symmetrically distributed on both sides of the end face of the adjusting seat 40, and hydraulic telescopic rods are adopted; it should be noted that whether hydraulic telescopic rods or electric telescopic rods are adopted, conventional models and structures in the field are used, and those skilled in the art can understand). The adjusting seat 40 is slidably arranged between the two legs of the portal bracket 20. Refer to Figure 1 As shown: lifting sliders 42 are respectively arranged on the upper side of the outer wall of the adjusting seat 40 corresponding to the two legs of the portal bracket 20, and vertical sliding grooves 22 are correspondingly opened on the inner walls of the two legs of the portal bracket 20. The lifting sliders 42 are slidably clamped in the corresponding vertical sliding grooves 22.
[0022] The middle part of the bottom surface of the adjusting seat 40 protrudes to form an inverted "convex" - shaped structure (as Figure 1 or Figure 2 As shown), and a cavity 41 is opened in the protruding part. A conical slider 50 is slidably arranged in the cavity 41, and the longitudinal section of the conical slider 50 is an isosceles trapezoid structure with a larger upper diameter and a smaller lower diameter (i.e., the upper diameter is large and the lower diameter is small) (as Figure 1 or Figure 2 As shown). The clamping mechanism is arranged on the lower side of the adjusting seat 40 and is connected to the bottom surface of the conical slider 50. The clamping mechanism includes a sliding column 61, a pressing plate 62, a return spring 63 and a rolling component. The top end of the sliding column 61 is fixedly connected to the bottom surface of the conical slider 50 (the sliding column 61 and the central axis of the conical slider 50 are collinear), and its bottom end penetrates through the corresponding bottom surface of the adjusting seat 40 and is fixedly connected to the end face of the pressing plate 62 arranged on the lower side of the adjusting seat 40. The length of the pressing plate 62 is not greater than the width of the protruding part of the adjusting seat 40 (as Figure 1 or as shown in Figure 2); a return spring 63 is arranged between the end face of the pressing plate 62 and the bottom surface of the adjusting seat 40 and on the outer circle of the sliding column 61; a rolling component is arranged on the bottom surface of the pressing plate 62. The rolling component can adopt a structure composed of a single roller and a roller shaft, or can also adopt a structure composed of multiple groups of rollers 642 and a roller shaft 641. In this embodiment, the latter is adopted, that is, rolling grooves are uniformly opened on the bottom surface of the pressing plate 62, and a rolling structure composed of rollers 642 and a roller shaft 641 is respectively arranged in the rolling grooves (as Figure 3As shown in the figure, the two ends of the roller 641 are rotatably connected to the inner wall of the corresponding rolling groove, and the roller 642 is fixedly sleeved on the outer wall of the corresponding roller 641.
[0023] The grinding mechanism consists of two sets, which are symmetrically arranged on both sides of the protrusion of the adjusting seat 40. The grinding mechanism is connected to the side of the conical slider 50. Specifically, the grinding mechanism includes a connecting block 71, a grinding bracket 72, a connecting rod 73, and a grinding column 74. The connecting block 71 is slidably arranged on the bottom surface of the adjusting seat 40 on both sides of the protrusion, and the grinding bracket 72 is fixedly arranged at the bottom of the connecting block 71. A translation slider 710 is provided on the end face of the connecting block 71. Horizontal grooves 43 are opened on the bottom surface of the adjusting seat 40 on both sides of the protrusion respectively corresponding to the translation slider 710. The translation slider 710 is slidably engaged in the horizontal groove 43. A connecting rod 73 is fixedly mounted on the side of the grinding bracket 72 near the conical slider 50. The end of the connecting rod 73 away from the grinding bracket 72 passes through the corresponding side wall of the protruding part of the adjusting seat 40 and is slidably engaged within the inclined surface of the conical slider 50 (i.e., one end of the connecting rod 73 is slidably connected to the corresponding inclined surface of the conical slider 50). A rotating grinding column 74 is mounted on the bottom surface of the grinding bracket 72 (the grinding column 74 is driven to rotate by a motor installed inside the grinding bracket 72, and the grinding bracket 72 also houses a central control module and a battery for controlling the motor's start; the motor, central control module, and battery all use existing conventional equipment). The diameter of the grinding column 74 is not greater than the width of the grinding bracket 72 (e.g., ...). Figure 1 or Figure 2 (As shown).
[0024] Working principle:
[0025] In use, first, place the cut wooden board 80 on the end face of the placement platform 11, aligning the two sides with the grinding edge with the two grinding mechanisms respectively. Then, extend the telescopic rod 30 to push the adjusting seat 40 downwards, thereby driving the clamping mechanism and the grinding mechanism to move downwards as a whole. During the downward movement, the bottom end of the roller 642 of the clamping mechanism contacts the end face of the wooden board 80 first, forming a pressing plate 62 to press and position the wooden board 80, preventing the wooden board 80 from jumping during the grinding process. As the adjusting seat 40 continues to move downwards, due to the relative force of the wooden board 80 on the pressing plate 62, the sliding column 61 pushes the conical slider 50 upwards relative to the cavity 61, thereby using the connecting rod 73 to pull the grinding brackets 72 on both sides to move closer to each other. The grinding brackets 72 drive the grinding column 74 to move closer to each other, thereby achieving the contact between the grinding column 74 and the corresponding side edge of the wooden board 80 (e.g., Figure 2 (As shown). Finally, start the grinding column 74 to rotate and control the gantry bracket 20 to slide along the sliding guide rail 12 to achieve the grinding of burrs and flash on the side of the wooden board 80.
[0026] Example 2:
[0027] As a further optimization of the present invention, based on the solution of embodiment 1, buffer rubber pads are respectively provided on the end face and bottom face of the conical slider 50 for buffering the lifting and lowering of the conical slider 50.
[0028] Example 3:
[0029] As a further optimization of the present utility model, based on the scheme of embodiment 1, the sliding seat 21 is driven to move on the sliding guide rail 12 by a ball screw. Specifically, a ball screw parallel to the sliding guide rail 12 is respectively set on the end face of the worktable 10 and located on the upper side of the two sliding guide rails 12. The ball screw passes through the middle of the corresponding sliding seat 21 and is threaded. The movement of the sliding seat 21 on the sliding guide rail 12 is driven by the rotation of the ball screw.
[0030] Meanwhile, in order to ensure the smooth movement of the portal frame 20, two guide rods are installed on the end face of the worktable 10 and above the ball screw, corresponding to the crossbeam of the portal frame 20. The guide rods pass through the crossbeam of the portal frame 20 and are slidably connected.
