[0025] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0026] like Figures 1-7 An adjustable wood board cutting machine is shown, comprising a worktable 1 and a cutting device disposed on the worktable 1. The cutting device includes support side plates 2 spaced apart on the worktable 1. A rotating outer cylinder 3 is rotatably connected between the two support side plates 2. An intermediate saw blade 4 is disposed on the rotating outer cylinder 3. Sliding sleeves 5 are slidably fitted on the rotating outer cylinder 3 on both sides of the intermediate saw blade 4. The sliding sleeves 5 can slide along the axial direction of the rotating outer cylinder 3 but cannot rotate around the circumference of the rotating outer cylinder 3. Side saw blades 6 are fixedly fitted on the outer side of the sliding sleeves 5. An adjustment device is also provided on the rotating outer cylinder 3 to drive the two sliding sleeves 5 to slide outward or inward simultaneously. A power device for driving the rotating outer cylinder 3 to rotate is also provided on the worktable 1.

[0027] Based on the above structure, the axial sliding cooperation between the rotating outer cylinder 3 and the sliding sleeve 5, combined with the adjustment device, enables the symmetrical synchronous movement of the saw blades 6 on both sides. Only a single operation is needed to quickly adjust the cutting width, significantly improving the adjustment efficiency. Compared with the traditional step-by-step adjustment method, it avoids human operation errors and ensures the precise centering of the distance between the two saw blades.

[0028] The middle saw blade 4 and the two side saw blades 6 form a combined cutting unit, which can complete multiple cuts (such as grooving and trimming) in a single operation. It can also be converted into a single saw mode by moving the side saw blades 6 outward through the adjustment device. This multi-purpose machine significantly expands the applicability of the equipment.

[0029] In addition, the rotating outer cylinder 3, as the core power transmission component, drives multiple saw blades to work in one piece, with good synchronization.

[0030] See Figure 5 , Figure 6 As shown, the rotating outer cylinder 3 is provided with a sliding groove 21 extending along the axial direction of the rotating outer cylinder 3, and a first slider 22 that slides in the sliding groove 21 is provided on the inner side wall of the sliding sleeve 5; the cooperative design of the sliding groove 21 and the first slider 22 provides stable axial guidance for the sliding sleeve 5.

[0031] Furthermore, the adjustment device includes a rotating inner cylinder 31 coaxially rotatably disposed within the rotating outer cylinder 3. An adjustment spiral groove 32 is provided on the outer wall of the rotating inner cylinder 31. A guide post 33 is provided on the first slider 22 within the adjustment spiral groove 32. A fixing component is also provided between the rotating outer cylinder 3 and the rotating inner cylinder 31 to fix the two together. Through the cooperation of the rotating inner cylinder 31 and the adjustment spiral groove 32, the rotational motion of the rotating inner cylinder 31 is converted into the linear movement of the sliding sleeve 5, realizing stepless adjustment and higher precision. The fixing component can lock the relative position of the rotating inner cylinder 31 and the outer cylinder 3 to prevent the saw blade from shifting due to vibration during processing.

[0032] Furthermore, both ends of the rotating inner cylinder 31 extend out of the rotating outer cylinder 3. The fixing assembly includes an assisting rotating member 41 located at the outer end of the rotating inner cylinder 31. A bolt 42 is threadedly connected to the outer end of the assisting rotating member 41. The threaded end of the bolt 42 can abut against the outer end face of the rotating outer cylinder 3. The assisting rotating member 41 facilitates manual driving of the rotating inner cylinder 31 to rotate. Then, the bolt 42 locks the rotating inner cylinder 31 and the rotating outer cylinder 3 through end face friction. The structure is simple and the locking is reliable.

[0033] In this utility model, the power device includes a motor 51 located on the lower side of the workbench 1, a first pulley 52 is provided on the output shaft of the motor 51, a second pulley 53 is provided on the rotating outer cylinder 3, and a belt 54 is sleeved between the first pulley 52 and the second pulley 53; the motor 51 is installed at the bottom of the workbench 1, the output shaft is connected to the first pulley 52 through a coupling or key, the second pulley 53 is installed at one end of the rotating outer cylinder 3, and the belt 54 is tensioned and sleeved between the two pulleys to form a power transmission link.

[0034] In this invention, there are limit strips 61 spaced on the left and right sides of the end face of the workbench 1; the limit strips 61 serve as the lateral positioning reference for the plate, assisting in rapid positioning, avoiding manual alignment errors, and improving the dimensional consistency of batch processing; of course, the limit strips 61 are detachable or adjustable to adapt to the processing needs of plates of different widths.

[0035] See Figure 1 , Figure 3 , Figure 7 As shown, an end plate 71 is connected to the upper end of the two supporting side plates 2. Elastic pressing components are provided on the end plate 71 and on both the front and rear sides of the middle saw blade 4. The elastic pressing components continuously press the board during the cutting process to prevent the wood from warping or shifting and to ensure the straightness of the cut.

[0036] Furthermore, the elastic pressing assembly includes movable plates 81 spaced apart on the end plate 71, a pressing roller 82 rotatably connected between the two movable plates 81 and below the end plate 71, and a connecting plate 83 connected between the two movable plates 81 and above the end plate 71. An arched frame 84 is also provided on the end plate 71. Vertical rods 85 are spaced apart on the upper end of the connecting plate 83. The vertical rods 85 pass through the arched frame 84 vertically, and a spring 86 is sleeved on the vertical rod 85. The upper end of the spring 86 abuts against the arched frame 84, and the lower end abuts against the connecting plate 83. The cooperative design of the spring 86 and the vertical rod 85 realizes the elastic floating of the pressing roller 82, which can adapt to the pressing of plates of different thicknesses.

[0037] Furthermore, a second slider 91 is provided on both the left and right sides of the connecting plate 83, and a vertical groove 92 is provided on both the left and right inner sides of the arched frame 84. The second slider 91 slides in the vertical groove 92. The cooperation between the second slider 91 and the vertical groove 92 restricts the lateral displacement of the pressing assembly and ensures that the pressing roller 82 always acts perpendicularly on the plate.
