Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood processing technology, and more specifically, to a multi-specification adjustable wood strip cutting device. Background Technology
[0002] In traditional wood panel processing, wood strips are typically slit to a fixed specification. This approach often forces companies to change slitting machines or make cumbersome adjustments to existing equipment when demands diversify, increasing production costs and reducing efficiency. Furthermore, current slitting equipment often yields unsatisfactory results when processing different types and widths of wood panels, easily producing uneven cuts and significant dimensional errors in the wood strips. These problems severely impact the quality of subsequent wood panel production and increase the risk of worker injury. Therefore, developing a slitting device capable of adapting to multi-specification wood strip slits with high precision and stability is of significant practical importance. Utility Model Content
[0003] This utility model provides a multi-specification adjustable wood strip slitting device, including a processing table and a slitting mechanism. The processing table includes a support, a workbench mounted on the support, and a downwardly inclined guide plate. The guide plate is spaced below one end of the workbench, and the workbench and the guide plate form a cutting path for the wood strip. The slitting mechanism is mounted on the support, located at the gap between the workbench and the guide plate. The slitting mechanism includes a lower cutting assembly and an upper cutting assembly. The lower cutting assembly includes a lower cutting shaft and a lower motor that drives the lower cutting shaft to rotate. The lower cutting shaft is mounted on the support, located at the bend between the workbench and the guide plate. The upper cutting assembly includes a slide rail adjustment unit, an upper cutting shaft mounted below the slide rail adjustment unit, and an upper motor. The upper motor drives the upper cutting shaft to rotate. Both the lower and upper cutting shafts have multiple saw blades arranged in an axially spaced array. The lower cutting axis and the upper cutting axis are offset and positioned along the direction of the cutting of the wooden board, with the lower cutting axis in front and the upper cutting axis behind. The vertical distance between the central axes of the upper cutting axis and the lower cutting axis is less than the diameter of the saw blade.
[0004] In some embodiments, the spacing between adjacent saw blades on the upper cutting axis is equal to the spacing between adjacent saw blades on the lower cutting axis.
[0005] In some embodiments, the edge of the worktable has an outwardly protruding portion that extends into the gap between adjacent saw blades of the lower cutting axis.
[0006] In some embodiments, the offset angle of the upper cutting axis centerline relative to the lower cutting axis centerline in the vertical direction is 15° to 35°.
[0007] In some embodiments, the lower cutting axis performs a preliminary cut on the wood board, and the upper cutting axis performs a secondary cut on the wood strips after the preliminary cut.

[0018] Please see Figures 1 to 3This utility model provides a multi-specification adjustable wood strip cutting device 100, including a processing table 10 and a cutting mechanism 20. The processing table 10 includes a support 11, a worktable 12 mounted on the support 11, and a downwardly inclined guide plate 13. The guide plate 13 is spaced below one end of the worktable 12, and the worktable 12 and the guide plate 13 form the cutting path of the wood board. The cutting mechanism 20 is mounted on the support 11 and located in the gap between the worktable 12 and the guide plate 13. The cutting mechanism 20 includes a lower cutting assembly 30 and an upper cutting assembly 40. The lower cutting assembly 30 includes a lower cutting shaft 31 and a lower motor 32 that drives the lower cutting shaft 31 to rotate. The lower cutting shaft 31 is mounted on the support 11 and located at the bend joint between the worktable 12 and the guide plate 13. The upper cutting assembly 40 includes a slide rail adjustment unit 41, an upper cutting shaft 42 and an upper motor 43 mounted below the slide rail adjustment unit 41, and the upper motor 43 drives the upper cutting shaft 42 to rotate. Both the lower cutting shaft 31 and the upper cutting shaft 42 have multiple saw blades 50 arranged in an axially spaced array. The lower cutting shaft 31 and the upper cutting shaft 42 are offset and positioned so that the lower cutting shaft 31 is in front and the upper cutting shaft 42 is behind along the direction of the wood board cutting. The vertical distance H between the central axes of the upper cutting shaft 42 and the lower cutting shaft 31 is less than the diameter of the saw blades 50.
[0019] The slitting device 100 of this invention adopts an adjustable dual-axis offset cutting design, effectively overcoming the limitations of traditional slitting devices 100. The slide rail adjustment unit 41 can achieve stepless adjustment of the saw blade 50 spacing, meeting the cutting needs of various specifications of wood chips, thereby reducing the frequency of equipment replacement. The combination design of the guide plate 13 and the offset cutting axis enables the wood board to automatically detach from the cutting area, effectively reducing the risk of workplace injuries.
[0020] Specifically, please refer to Figure 1 and Figure 2 The processing table 10 is used to place and push the sheet material to be processed. The processing table 10 includes a support 11 and a worktable 12. The support 11 supports the worktable 12 to maintain a stable working height and position. The surface of the worktable 12 is flat and smooth to ensure that the sheet material can be placed stably and moved smoothly.
[0021] The slitting mechanism 20 is mounted on the support 11 and located on one edge of the worktable 12. The slitting mechanism 20 includes a lower cutting assembly 30 and an upper cutting assembly 40 mounted on the support 11. The lower cutting assembly 30 includes a lower cutting shaft 31 and a lower motor 32. Multiple saw blades 50 are arranged in an array on the lower cutting shaft 31, and the lower motor 32 drives the lower cutting shaft 31 to rotate counterclockwise. The lower cutting shaft 31 is mounted on the edge of the worktable 12, with the saw blades 50 on it slightly protruding above the worktable surface. The lower motor 31 is belt-connected to the input shaft of the reducer 33, and the output shaft of the reducer 33 is chain-connected to the lower cutting shaft 31 for drive.
[0022] The worktable 12 protrudes outward to form a protrusion 121 that extends into the gaps between the saw blades 50. The protrusion 121 can prevent the plate from shifting during the cutting process and ensure the cutting accuracy.
[0023] The upper cutting assembly 40 includes a slide rail adjustment unit 41, an upper cutting shaft 42, and an upper motor 43. The slide rail adjustment unit 41 includes a slide block 411, a slider 412 that moves along the length of the slide block 411, an adjustment motor 413, and a screw shaft 414 driven by the adjustment motor 413. The screw shaft 414 drives the slider 412 to move. The length direction of the slide rail adjustment unit 41 is parallel to the axial direction of the upper cutting shaft 42, and their central axes are on the same vertical plane. The slider 412 can move along the length direction of the slide block 411. The upper cutting shaft 42 and the upper motor 43 are both mounted on the lower surface of the slider 412, and the upper cutting shaft 42 is arranged parallel to the lower cutting shaft 31. The upper cutting shaft 42 also has several saw blades 50 spaced at equal intervals. The upper motor 43 drives the upper cutting shaft 42 and the saw blades 50 to rotate clockwise to cut the wood board, facilitating efficient wood board cutting operations. The upper cutting shaft 42 can drive the slider 412 to move axially by adjusting the motor 413, thereby precisely adjusting the position of the saw blade 50 and flexibly adjusting the relative position between the saw blades 50 to meet the cutting needs of different specifications of wood boards.
[0024] Please see Figure 3 The central axes of the upper cutting axis 42 and the lower cutting axis 31 are offset. Along the direction of the wood cutting, the upper cutting axis 42 is positioned behind, and the lower cutting axis 31 is positioned below. The upper and lower saw blades 50 are tangent or slightly spaced. Therefore, the vertical distance between the central axes of the upper cutting axis 42 and the lower cutting axis 31 is less than the diameter of the saw blade 50. Furthermore, using the axis of the lower cutting axis 31 as a reference point, the offset angle B of the upper cutting axis 42 relative to the vertical direction is between 15 and 35 degrees (inclusive). Through this carefully designed offset angle, the upper cutting axis 42 and the lower cutting axis 31 can work together to achieve efficient and precise cutting of the wood.
[0025] Please see Figure 2 The support 11 is provided with a guide plate 13 with its tail end tilted downward. The guide plate 13 is used to receive the cut wood strips away from the lower cutting axis 31. Its higher end is close to the lower cutting axis 31. The worktable 12 and the guide plate 13 form the cutting path of the wood board, while the upper cutting axis 42 and the lower cutting axis 31 are located at the bend where the worktable 12 and the guide plate 13 meet.
[0026] The wooden board is first initially cut by the lower cutting shaft 31, and then further cut into smaller pieces by the upper cutting shaft 42. At this point, the center of gravity of the wooden board is still on the worktable 12. When the center of gravity of the wooden board moves away from the worktable 12 and transitions to the guide plate 13, the wooden board is still mechanically cut due to the action of the guide plate 13 and the offset setting of the upper / lower cutting shafts 31. After the center of the wooden board leaves the worktable 12, it can fall freely by relying on inertia and cutting force, maintaining the cut and preventing injury to the worker.
[0027] During operation, the worker first uses the lower cutting axis 31 to make a preliminary cut on the wooden board, and then uses the upper cutting axis 42 to further divide the board into smaller pieces. Throughout this process, the center of gravity of the wooden board remains on the worktable 12. When the center of gravity of the wooden board shifts from the worktable 12 to the guide plate 13, the board can continue to be mechanically cut due to the guiding effect of the guide plate 13 and the offset design of the upper / lower cutting axes. Once the center portion of the board leaves the worktable 12, it can fall freely due to inertia and cutting force, thus maintaining the continuity of the cutting process and preventing injury to the worker.
