Description

Technical Field

[0001] This utility model relates to the field of wood processing equipment, specifically to a multi-blade band saw. Background Technology

[0002] In the wood processing industry, woodworking band saws are widely used for cutting wood. During processing, the motor drives the active and passive band saw wheels to rotate, and the band saw blade is wrapped around them. The wood is fed into the feed end through the worktable and is cut into boards of the required specifications in sequence.

[0003] However, existing woodworking band saw equipment still has many shortcomings in practical applications: during long-term operation, the band saw wheel may shift position due to uneven force, wear, or assembly errors. However, existing equipment usually does not have the function of adjusting the offset position of the band saw wheel, which leads to a decrease in sawing accuracy and affects the quality of the board. At the same time, the unadjustable band saw wheel may also cause the band saw blade to run off-center and aggravate the uneven wear of the band saw blade, shorten its service life, and thus increase production costs. Utility Model Content

[0004] To overcome the defects described in the prior art, this utility model provides a multi-blade band saw machine. By adjusting the plate and the first connecting component to form a wedge movement, the first band saw wheel can be kept horizontal, avoiding the band saw blade from shifting due to inconsistent left and right heights. This improves sawing accuracy and stability during the sawing process, while also extending the service life of the band saw blade, reducing equipment maintenance frequency, and lowering production costs.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A multi-blade band saw includes:

[0007] The rack has a first mounting position and a second mounting position;

[0008] A first band saw wheel is mounted on the frame via a rotating shaft; one end of the rotating shaft is mounted on the first mounting position via a first connecting assembly, and the other end is mounted on the second mounting position via a second connecting assembly.

[0009] It also includes an adjustment plate. When the position of the adjustment plate is adjusted, the adjustment plate and the first connecting component form a wedge movement to adjust the height of one end of the rotating shaft relative to the other end, thereby changing the height of both sides of the first band saw wheel.

[0010] Furthermore, the first connecting assembly includes a first connecting shaft connected to one end of the rotating shaft and a first mounting base connected to the first connecting shaft. The adjusting plate is provided with a first mounting slope, and the first mounting base is mounted on the first mounting slope.

[0011] When the position of the adjustment plate is adjusted, the position of the first mounting base on the first mounting slope can be changed, thereby adjusting the height of one end of the rotating shaft relative to the other end.

[0012] Furthermore, the bottom of the first mounting base is provided with a second mounting inclined surface that cooperates with the first mounting inclined surface. When the position of the adjusting plate is adjusted, the first mounting inclined surface and the second mounting inclined surface slide against each other so that the first mounting base and the adjusting plate move in a wedge-like motion.

[0013] Furthermore, a mounting hole is provided on the first mounting slope, and the first mounting base is fixed to the first mounting position after passing through the mounting hole by a first fastener.

[0014] Furthermore, the adjusting plate includes a first plate body arranged horizontally and installed on the first mounting position and a second plate body arranged vertically. The first plate body has a groove, and the first mounting inclined surface is formed in the groove.

[0015] The second plate has screw holes, and the second fastener can be screwed into the screw holes and pressed against the frame to adjust the position of the adjustment plate.

[0016] Furthermore, a first connecting hole is provided on one side of the first mounting base, and a first screw hole is provided on the other side. The first connecting shaft passes through the first connecting hole. The first connecting shaft can be changed by screwing a third fastener into the first screw hole and pressing it against the first connecting shaft, thereby adjusting the offset position of one end of the rotating shaft.

[0017] Furthermore, the second connecting assembly also includes a second connecting shaft connected to the other end of the rotating shaft and a second mounting base connected to the second connecting shaft, the second mounting base being fixedly installed on the second mounting position.

[0018] Furthermore, a second connecting hole is provided on one side of the second mounting base, and a second screw hole is provided on the other side. The second connecting shaft passes through the second connecting hole. The second connecting shaft can be changed by screwing a fourth fastener into the second screw hole and pressing it against the second connecting shaft, thereby adjusting the offset position of the other end of the rotating shaft.

[0019] Furthermore, a third connecting hole is provided on the first connecting shaft, and a fourth connecting hole is provided on the second connecting shaft. One end of the rotating shaft passes through the third connecting hole, and the other end passes through the fourth connecting hole.

[0020] The first connecting shaft is also provided with a third screw hole that allows the fifth fastener to be screwed in, and the second connecting shaft is also provided with a fourth screw hole that allows the sixth fastener to be screwed in.

[0021] When the fifth fastener is screwed into the third screw hole and presses against one end of the rotating shaft, it drives one end of the rotating shaft to move to the other end.

[0022] Alternatively, when the sixth fastener is screwed into the fourth screw hole and presses against the other end of the shaft, the other end of the shaft is driven to move to one side.

[0023] Furthermore, it also includes a second band saw wheel, and the frame is equipped with a drive motor that is pulsatorically connected to the second band saw wheel. The second band saw wheel and the first band saw wheel are pulsatorically connected via a band saw blade.

[0024] In summary, this utility model has the following technical effects:

[0025] 1. The multi-blade band saw of this utility model forms a wedge block movement with the adjusting plate and the first connecting component, so that the first band saw wheel can be kept horizontal, avoiding the band saw blade from running off due to inconsistent height on the left and right sides, improving the sawing accuracy and stability during the sawing process, while extending the service life of the band saw blade, reducing the frequency of equipment maintenance, and reducing production costs.

[0026] 2. The multi-blade band saw of this utility model is equipped with an adjustment mechanism formed by the addition of a third, fourth, fifth, and sixth fasteners. This allows the operator to adjust the left and right positions of the first band saw wheel according to processing requirements, further preventing uneven wear of the band saw blade due to inconsistent left and right positions. This not only reduces the difficulty of equipment maintenance but also extends the service life of the band saw blade and improves the overall economic benefits of the equipment.

[0035] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] like Figure 1-6The multi-blade band saw shown includes a frame 1, a first band saw wheel 2, and an adjusting plate 3. The frame 1 is provided with a first mounting position 11 and a second mounting position 12. The first band saw wheel 2 is mounted on the frame 1 through a rotating shaft 21. One end of the rotating shaft 21 is mounted on the first mounting position 11 through a first connecting component, and the other end is mounted on the second mounting position 12 through a second connecting component. The adjusting plate 3 is also included. When the position of the adjusting plate 3 is adjusted, the adjusting plate 3 and the first connecting component form a wedge movement to adjust the height of one end of the rotating shaft 21 relative to the other end, thereby changing the height of both sides of the first band saw wheel 2.

[0039] Therefore, the multi-blade band saw of this invention, through the wedge movement formed by the adjusting plate 3 and the first connecting component, enables the first band saw wheel 2 to remain horizontal, avoiding the band saw blade 13 from shifting due to inconsistent left and right heights, improving sawing accuracy and stability during the sawing process, while extending the service life of the band saw blade 13, reducing equipment maintenance frequency, and solving the problem of positional displacement of the band saw wheel caused by long-term uneven force, wear, or assembly errors in existing equipment, ensuring that the band saw blade 13 maintains a stable cutting trajectory during operation, improving sawing accuracy, and enhancing the quality of plate processing.

[0040] Furthermore, the first connecting assembly also includes a first connecting shaft 6 connected to one end of the rotating shaft 21 and a first mounting base 4 connected to the first connecting shaft 6. The adjusting plate 3 is provided with a first mounting slope 312, and the first mounting base 4 is mounted on the first mounting slope 312. When the position of the adjusting plate 3 is adjusted, the position of the first mounting base 4 on the first mounting slope 312 can be changed to adjust the height of one end of the rotating shaft 21 relative to its other end, thereby optimizing the height of both sides of the first band saw wheel 2, so that the first band saw wheel 2 can remain horizontal, and improve sawing stability and processing accuracy.

[0041] Specifically, the bottom of the first mounting base 4 is provided with a second mounting slope 43 that cooperates with the first mounting slope 312 on the adjusting plate 3. When the position of the adjusting plate 3 is adjusted, the first mounting slope 312 and the second mounting slope 43 slide relative to each other, so that the first mounting base 4 moves along the first mounting slope 312 of the adjusting plate 3, thereby forming a wedge-type adjustment structure. This structure can precisely adjust the height of the first mounting base 4, achieve fine adjustment of the height of the rotating shaft 21, optimize the height of both sides of the first band saw wheel 2, and improve the sawing accuracy and equipment stability.

[0042] More specifically, the first mounting slope 312 is provided with a mounting hole 313, and the first mounting base 4 is fixed to the first mounting position 11 after passing through the mounting hole 313 with a first fastener; wherein, the mounting hole 313 is an oblong hole.

[0043] Furthermore, the adjusting plate 3 includes a first plate 31 arranged horizontally and installed on the first mounting position 11, and a second plate 32 arranged vertically. The first plate 31 has a groove 311, and the first mounting inclined surface 312 is opened in the groove 311. The second plate 32 has a screw hole 321. After the second fastener is screwed into the screw hole 321 and presses against the frame 1, the position of the adjusting plate 3 can be adjusted. Through the waist-shaped hole, when the second fastener is pressing against the frame 1, the first mounting inclined surface 312 on the adjusting plate 3 and the second mounting inclined surface 43 on the first mounting seat 4 move like a wedge and slide out or in relative to the frame 1, thereby adjusting the height of one end of the rotating shaft 21 relative to its other end to change the height of both sides of the first band saw wheel 2.

[0044] See Figure 4-6 The first mounting base 4 has a first connecting hole 41 on one side and a first screw hole 42 on the other side. The first connecting shaft 6 passes through the first connecting hole 41. The first connecting shaft 6 can be screwed into the first screw hole 42 by a third fastener and pressed against it to change the depth position of the first connecting shaft 6 in the first connecting hole 41, thereby adjusting the offset position of one end of the rotating shaft 21, effectively controlling the axial position of the first connecting shaft 6, and thus achieving precise adjustment of one end of the rotating shaft 21.

[0045] Specifically, the second connecting assembly also includes a second connecting shaft 7 connected to the other end of the rotating shaft 21 and a second mounting base 5 connected to the second connecting shaft 7, the second mounting base 5 being fixedly mounted on the second mounting position 12.

[0046] Furthermore, the second mounting base 5 has a second connecting hole 51 on one side and a second screw hole 52 on the other side; the second connecting shaft 7 passes through the second connecting hole 51; the second connecting shaft 7 can be screwed into the second screw hole 52 by the fourth fastener and pressed against the second connecting shaft 7 to change the depth position of the second connecting shaft 7 in the second connecting hole 51, thereby adjusting the offset position of the other end of the rotating shaft 21, so that the other end of the rotating shaft 21 can be precisely adjusted to ensure sawing accuracy, while reducing the wear of the band saw blade 13 caused by positional offset during equipment operation, and improving the overall stability and service life of the equipment.

[0047] Specifically, the first connecting shaft 6 has a third connecting hole 61, and the second connecting shaft 7 has a fourth connecting hole 71. One end of the rotating shaft 21 passes through the third connecting hole 61, and the other end passes through the fourth connecting hole 71. The first connecting shaft also has a third screw hole 62 that allows a fifth fastener to be screwed in, and the second connecting shaft 7 also has a fourth screw hole 72 that allows a sixth fastener to be screwed in. When the fifth fastener is screwed into the third screw hole 62 and presses against one end of the rotating shaft 21, it drives one end of the rotating shaft 21 to move to the other end. Alternatively, when the sixth fastener is screwed into the fourth screw hole 72 and presses against the other end of the rotating shaft 21, it drives the other end of the rotating shaft 21 to move to one end. This effectively realizes the axial position adjustment of the rotating shaft 21, improves the installation flexibility of the first band saw wheel 2, ensures sawing accuracy, and reduces abnormal wear of the band saw blade 13 due to positional offset.

[0048] See Figure 1-2 The multi-blade band saw of this utility model also includes a second band saw wheel 8. The frame 1 is equipped with a drive motor 9 that is connected to the second band saw wheel 8. The second band saw wheel 8 and the first band saw wheel 2 are connected by a band saw blade 13.

[0049] See also Figure 6 The first band saw wheel 2 and the second band saw wheel 8 are provided with multiple and arranged in a stepped manner. The rotating shaft 21 is provided with multiple bearings 22 arranged at intervals, so that multiple first band saw wheels 2 can be mounted on multiple bearings 22 to achieve installation on the rotating shaft 21.

[0050] In summary, the multi-blade band saw of this invention adjusts the height of the two sides of the first band saw wheel 2 by adjusting the wedge block movement of the adjustment plate, so that the first band saw wheel 2 can be kept horizontal, avoiding the band saw blade 13 from running off due to inconsistent height on the left and right sides, improving the sawing accuracy and stability during the sawing process, while extending the service life of the band saw blade 13, reducing the frequency of equipment maintenance, and reducing production costs.

[0051] This utility model of a multi-blade band saw machine adds an adjustment mechanism formed by a third, fourth, fifth, and sixth fastener, enabling operators to adjust the left and right positions of the first band saw wheel 2 according to processing needs. This further avoids uneven wear of the band saw blade 13 due to inconsistent left and right positions, which not only reduces the difficulty of equipment maintenance but also extends the service life of the band saw blade 13 and improves the overall economic benefits of the equipment.

[0052] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

[0053] It should be understood that the terms "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0054] Furthermore, in the description of this utility model, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0055] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
