Description

Technical Field

[0001] This invention relates to the field of wood polishing technology, and in particular to a wood side polishing machine. Background Technology

[0002] The flatness of the sides of a wooden board is a core quality indicator for wood processing products, directly determining the assembly precision, connection stability, and appearance of the product. Therefore, the side polishing process plays an important role in wood processing.

[0003] Currently, most wood panel side polishing equipment on the market consists of a mounting frame, polishing components, and a placement structure. The polishing components polish the sides of the wood panels positioned within the placement structure to achieve a smooth and flat finish. However, most existing equipment only supports single-pane polishing operations. Even those machines that claim to be able to process in batches still require manual placement of each panel, leading to frequent machine stops for loading, unloading, and repositioning. This not only increases labor intensity but also significantly reduces production efficiency, making it difficult to meet the actual needs of large-scale mass production in the current wood processing industry. Summary of the Invention

[0004] This invention provides a wood board side polishing machine, which can solve the problem mentioned in the background art that the existing technology is difficult to adapt to the actual needs of large-scale mass production in the current wood processing industry.

Once the first placement frame is finished, the machine can be switched directly to the second placement frame for operation, eliminating the need to stop the machine to wait for loading and solving the problem of frequent downtime in traditional equipment. Simultaneously, a dust collection component connected to the top of the polishing components can continuously absorb wood dust generated during polishing, ensuring a clean working environment and preventing dust from affecting polishing accuracy. Ultimately, through the coordinated operation of these structures, continuous, batch, and efficient polishing of wood panel sides is achieved, perfectly meeting the large-scale production needs of the wood processing industry.

[0024] Example 1: like Figure 1-3 As shown, this invention proposes a wood panel side polishing machine, including a mounting frame 1, a polishing frame 2 in the middle of the mounting frame 1, a polishing component 3 for polishing the side of the wood panel disposed in the polishing frame 2, and a dust suction component 4 connected to the top of the polishing component 3; a first placement frame 5 and a second placement frame 6 are respectively disposed on both sides of the polishing frame 2, and both the first placement frame 5 and the second placement frame 6 are used to support multiple wood panels placed vertically side by side; a driving component 7 is installed in the mounting frame 1, and the driving component 7 is connected to the first placement frame 5 and the second placement frame 6 for driving them to alternately enter and exit the polishing frame 2, so that the top sides of the multiple wood panels supported by the first placement frame 5 or the second placement frame 6 entering the polishing frame 2 are polished synchronously by the polishing component 3.

[0025] In this embodiment, the polishing component 3 configured inside the polishing frame 2 can simultaneously polish the top and sides of multiple wooden boards entering the frame, significantly improving processing efficiency. Both the first placement frame 5 and the second placement frame 6 can support multiple vertically placed wooden boards side-by-side, enabling batch loading and pre-processing without manual placement of each board, significantly reducing labor intensity. The drive component 7 is connected to the two placement frames, allowing them to alternately enter and exit the polishing frame 2. That is, when the first placement frame 5 enters the polishing frame 2 for batch polishing by the polishing component 3, the operator can simultaneously prepare the second placement frame 6 for loading. After the first placement frame 5 finishes polishing, the operator can directly switch to the second placement frame 6 for operation, without stopping the machine to wait for loading, solving the problem of frequent machine downtime in traditional equipment. Simultaneously, the dust collection component 4 connected to the top of the polishing component 3 can absorb the sawdust generated during polishing in real time, ensuring a clean working environment and preventing dust from affecting polishing accuracy. Ultimately, through the coordinated operation of these structures, continuous, batch, and efficient polishing of the wooden board sides is achieved, perfectly meeting the large-scale production needs of the wood processing industry.

[0026] like Figure 2 and Figure 3 As shown, the polishing assembly 3 includes a first motor housing 31 and a second motor housing 32. The first motor housing 31 and the second motor housing 32 are horizontally mounted side by side on the polishing frame 2. The drive ends of the first motor housing 31 and the second motor housing 32 are both connected to polishing rollers 33.

[0027] In this embodiment, the first motor housing 31 and the second motor housing 32 are horizontally mounted side by side in the polishing frame 2 to form a symmetrical and stable dual-power drive structure. This structure can provide independent and uniform driving force to the two sets of polishing rollers 33 at the same time, ensuring that the top sides of multiple side-by-side wooden boards can contact the polishing rollers 33 simultaneously for polishing, which greatly shortens the polishing time per batch. The two sets of polishing rollers 33 are arranged in a corresponding manner, which can form a bidirectional polishing effect on the sides of the wooden boards. This not only quickly removes burrs and uneven defects from the wood, but also improves the flatness and smoothness of the side surface through the synergistic squeezing and polishing of the two rollers, avoiding the uneven polishing and corner residue problems that are easy to occur with single-roller polishing.

[0028] Specifically, the speed of a single motor can be flexibly adjusted according to the material and thickness of the wood board to adapt to different processing requirements.

[0029] like Figure 2 and Figure 3 As shown, the vacuuming assembly 4 includes a vacuuming frame 41, which is connected to the top of the polishing frame 2. A vacuuming pipe 42 is connected to the top of the vacuuming frame 41 and is connected to a vacuuming device.

[0030] In this embodiment, the dust collection frame 41 is directly connected to the top of the polishing frame 2, and its opening precisely corresponds to the working area of ​​the polishing roller 33 of the polishing component 3. It can completely cover the wood dust generated during the polishing process and prevent the dust from spreading to the surrounding environment. The dust collection pipe 42 connected to the top of the dust collection frame 41 forms an efficient dust collection channel with the external dust collection equipment. Through negative pressure adsorption, the dust in the polishing frame 2 is quickly drawn away from the working area to prevent dust particles from interfering with the polishing accuracy.

[0031] like Figure 1 and Figure 2 As shown, the drive assembly 7 includes a control box 71. The drive end of the control box 71 is connected to a first lead screw 72 and a second lead screw 73. The first lead screw 72 is threadedly connected to the first placement frame 5, and the second lead screw 73 is threadedly connected to the second placement frame 6. A first limiting rod 74 is provided on one side of the first lead screw 72, and a second limiting rod 75 is provided on one side of the second lead screw 73.

[0032] In this embodiment, the rotation of the first lead screw 72 and the second lead screw 73 can be controlled synchronously or independently by the control box 71. Through the threaded connection between the lead screw and the first placement frame 5 and the second placement frame 6, the rotational motion is converted into linear motion, driving the two to smoothly alternately enter and exit the polishing frame 2. Together with the polishing assembly 3, continuous batch polishing is achieved, solving the efficiency problem of frequent machine stoppages for material loading in traditional equipment. The first limit rod 74 and the second limit rod 75 are respectively set on one side of the first lead screw 72 and the second lead screw 73, and slide with the placement frame. They can accurately constrain the movement trajectory of the placement frame, preventing it from shifting, tilting or shaking during translation, ensuring that the top side of the multiple side-by-side wooden boards in the frame is always accurately aligned with the polishing roller 33, and ensuring uniform polishing accuracy.

[0033] Specifically, the moving speed and stroke of the placement frame can be precisely adjusted through the control box 71 to adapt to the processing needs of wood boards of different thicknesses and lengths. The supporting effect of the limit rod can disperse the load pressure of the placement frame, prevent the lead screw from being deformed due to long-term stress, thus affecting the transmission stability and extending the service life of the equipment.

[0034] Specifically, the control box 71 is equipped with a first drive motor and a second drive motor. The drive end of the first drive motor is connected to the first lead screw 72, and the drive end of the second drive motor is connected to the second lead screw 73.

[0035] like Figure 2 and Figure 4 As shown, the bottom of the first placement frame 5 is provided with a first threaded hole 51, a first limiting hole 52 and two first positioning holes 53. The first threaded hole 51 is adapted to the first lead screw 72, the first limiting hole 52 is adapted to the first limiting rod 74, and the diameter of the first positioning hole 53 is larger than the diameter of the first lead screw 72 and the first limiting rod 74.

[0036] In this embodiment, the first threaded hole 51 and the first lead screw 72 are precisely matched to ensure a reliable threaded transmission. When the control box 71 drives the first lead screw 72 to rotate, it can be efficiently converted into the linear motion of the first placement frame 5, ensuring its smooth entry and exit from the polishing frame 2. This, combined with the polishing assembly 3, enables precise alignment and polishing of batches of wooden boards. The first limiting hole 52 and the first limiting rod 74 are slidably matched to strictly constrain the movement trajectory of the first placement frame 5, preventing it from shifting or tilting during translation. This ensures that the top side of the wooden board inside the frame always remains parallel and in contact with the polishing roller 33, improving the uniformity of polishing accuracy. The diameters of the two first positioning holes 53 are larger than the diameters of the first lead screw 72 and the first limiting rod 74, providing convenient guidance for the first lead screw 72 and the first limiting rod 74 during equipment assembly or placement frame disassembly, reducing installation difficulty.

[0037] like Figure 2 and Figure 4 As shown, the bottom of the second placement frame 6 is provided with a second threaded hole 61, a second limiting hole 62 and two second positioning holes 63. The second threaded hole 61 is adapted to the second lead screw 73, the second limiting hole 62 is adapted to the second limiting rod 75, and the diameter of the second positioning hole 63 is larger than the diameter of the second lead screw 73 and the second limiting rod 75.

[0038] In this embodiment, the second threaded hole 61 and the second lead screw 73 are precisely threadedly matched to ensure that when the control box 71 drives the second lead screw 73 to rotate, the rotational power can be smoothly converted into the linear motion of the second placement frame 6, allowing it to smoothly alternate with the first placement frame 5 in and out of the polishing frame 2, achieving a continuous operation mode and avoiding the efficiency loss of traditional equipment when stopping to load materials; the second limiting hole 62 and the second limiting rod 75 slide together to strictly constrain the translational trajectory of the second placement frame 6, effectively preventing it from shifting, tilting or shaking when carrying multiple wooden boards, ensuring that the top side of the wooden board in the frame is always precisely aligned with the polishing roller 33 of the polishing component 3, and ensuring the accuracy and uniformity of batch polishing; the diameter of the two second positioning holes 63 is larger than the diameter of the second lead screw 73 and the second limiting rod 75, providing convenient guide space for equipment assembly or disassembly and assembly of the second placement frame 6, reducing the difficulty of installation and maintenance.

[0039] Example 2: like Figure 5 and Figure 6 As shown, adjustment components 8 are provided on both sides of the first placement frame 5 and the second placement frame 6, and positioning components 9 are provided on the other two sides of the first placement frame 5 and the second placement frame 6. Multiple rollers 10 are connected to the sides of both the adjustment components 8 and the positioning components 9.

[0040] In this embodiment, the spacing can be flexibly adjusted according to the width of the wooden board by adjusting component 8, and together with positioning component 9, it forms a bidirectional limit for multiple side-by-side wooden boards in the frame, ensuring that the wooden boards are neatly arranged in a vertical position, avoiding uneven side polishing caused by the offset of the wooden boards during the polishing process, and adapting to the processing needs of wooden boards of different widths, thus enhancing the versatility of the equipment.

[0041] Specifically, by adjusting the multiple rollers 10 connected to the side of the component 8 and the positioning component 9, the sliding friction between the wood board and the component is converted into rolling friction. On the one hand, this greatly reduces the resistance when the wood board is put into or taken out of the placement frame, making it easier for operators to quickly load and unload materials in batches and reduce labor intensity. On the other hand, it can reduce scratches and damage to the surface of the wood board caused by friction and ensure the quality of wood processing.

[0042] like Figure 6 and Figure 7 As shown, the adjustment assembly 8 includes an adjustment frame 81. One side of the adjustment frame 81 is connected to the adjustment screw 83 via a first bearing seat 82. The adjustment screw 83 is threadedly connected to the first placement frame 5. A first drive block 84 is connected to the end of the adjustment screw 83.

[0043] In this embodiment, by adjusting the threaded connection structure between the screw 83 and the first placement frame 5, the manual rotation operation of the first drive block 84 can be converted into the linear translational movement of the adjustment frame 81. The operator can precisely control the spacing of the adjustment frame 81 by rotating the first drive block 84, quickly adapting to wooden boards of different widths without the need to change special fixtures, significantly improving the versatility of the equipment. Together with the positioning component 9, a reliable bidirectional limit is formed, ensuring that multiple wooden boards in the frame are always neatly arranged, ensuring that their top sides are precisely aligned with the polishing roller 33 of the polishing component 3, avoiding uneven polishing caused by wooden board misalignment, further improving the accuracy and consistency of batch processing, and reducing the labor intensity and time cost of manual adjustment.

[0044] like Figure 6 and Figure 7 As shown, the positioning component 9 includes a positioning frame 91. One side of the positioning frame 91 is connected to the positioning screw 93 via a second bearing seat 92. The positioning screw 93 is threadedly connected to the second placement frame 6. A second drive block 94 is connected to the end of the positioning screw 93.

[0045] In this embodiment, the threaded connection between the positioning screw 93 and the second placement frame 6 can convert the manual rotation of the second drive block 94 into the linear translation of the positioning frame 91. The operator can precisely adjust the distance between the positioning frame 91 and the adjustment component 8 by rotating the second drive block 94, quickly adapting to wooden boards of different widths. Positioning adjustment can be completed without complicated tools, significantly reducing the difficulty of operation and time cost. Together with the adjustment component 8, a bidirectional rigid limit is formed to ensure that multiple side-by-side wooden boards in the frame always remain neatly arranged, ensuring that the top side of the wooden board is precisely aligned with the polishing roller 33 of the polishing component 3. This avoids problems such as uneven side polishing and precision deviation caused by the movement of the wooden board during the polishing process, further improving the quality consistency of batch polishing and adapting to the diversified and large-scale production needs of the wood processing industry.

[0046] like Figure 6 and Figure 8 As shown, both the adjustment frame 81 and the positioning frame 91 are connected to multiple rollers 10.

[0047] In this embodiment, multiple rollers 10 are evenly distributed on the inner force-bearing surfaces of the adjusting frame 81 and the positioning frame 91. On the one hand, they convert the sliding friction between the wooden board and the frame into rolling friction, significantly reducing the contact resistance when the wooden boards are placed into and removed from the frame in batches. This facilitates the operators to quickly complete the loading and unloading operations, reducing labor intensity, and also prevents scratches and damage to the surface of the wooden boards due to friction, ensuring the quality of wood processing. On the other hand, within the bidirectional limiting space formed by the adjusting frame 81 and the positioning frame 91, the rollers 10 can provide flexible support for vertically placed wooden boards. The rolling characteristics of the rollers help the wooden boards to quickly align and arrange, ensuring that the sides of multiple wooden boards are flush and ensuring precise docking with the polishing rollers 33 of the polishing assembly 3. They can also absorb equipment vibration and small displacement of the wooden boards during the polishing process, preventing edge and corner damage caused by rigid compression. At the same time, it does not affect the flexibility of adjusting the spacing of the adjusting frame 81 and the positioning frame 91 through the screw, so that the equipment can adapt to wooden boards of different widths while always maintaining the consistency of batch polishing precision, fully adapting to the needs of large-scale production.

[0048] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
