[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] See also Figures 1 to 6 The utility model discloses a wood sawing machine for preventing band saw from breaking, comprising a machine body 10, a saw blade 23 assembly and a driving assembly 60, wherein the saw blade 23 assembly comprises a saw blade 23 and at least two saw wheels, wherein the two saw wheels are arranged at intervals up and down along the height direction of the machine body 10 and form a processing interval 13, and then one end of the saw blade 23 is wound around one of the saw wheels, and the other end of the saw blade 23 is wound around the other saw wheel, and the linear transmission section of the saw blade 23 located between the saw wheels passes through the processing interval 13 and forms a saw blade processing section 231, and the driving assembly 60 can be used to drive the saw wheel to rotate, and when the saw wheel rotates, the saw blade 23 can be driven to rotate, so as to guide the saw blade processing section 231 to move along a processing direction;

[0034] In addition, buffer belts 30 are respectively sleeved on the two saw wheels. The buffer belts 30 are made of flexible material and are clamped between the outer surface of the saw wheel and the saw blade 23 .

[0035] On the basis of the above structure, during assembly, the two saw wheels can be arranged along the height direction of the machine body 10, respectively installed on the top and bottom of the machine body 10, and the two can be arranged at an interval so that the interval between the two forms a processing interval 13, and then the two ends of the saw blade 23 are respectively wrapped around the two saw wheels, and the saw blade 23 is located in the linear transmission section between the two saw wheels and can be formed into a saw blade processing section 231. Then, after connecting the drive component 60 to one of the saw wheels, starting the drive component 60 can drive one of the saw wheels to rotate. Since the two saw wheels are wrapped around by the saw blade 23, when one of the saw wheels rotates, the saw blade 23 can rotate synchronously and drive the other saw wheel to rotate at the same time. At this time, the saw blade processing section 231 located at the processing interval 13 can cut the workpiece at the processing interval 13 during the rotation process.

[0036] Specifically, since flexible buffer belts 30 are sleeved on both saw wheels, the flexible buffer belts 30 can absorb and disperse the impact and vibration generated by the collision between the saw blade 23 and the saw wheel during high-speed operation. Such impact and vibration are one of the main sources of stress fatigue of the saw blade 23. Therefore, the stress on the saw blade 23 can be significantly reduced through the absorption and dispersion of the buffer belt 30, thereby reducing the stress fatigue of the saw blade 23.

[0037] More specifically, since the flexible buffer belt 30 usually has a rougher surface, after it is mounted on the periphery of the saw wheel, the friction of the periphery of the saw wheel is improved. Higher friction means that the saw wheel can better drive the saw blade 23, reduce slippage, and improve sawing efficiency and stability. In addition, the flexible buffer belt 30 acts as a "spring" when clamped between the saw blade 23 and the saw wheel. When the saw blade 23 is subjected to tension, the buffer belt 30 partially absorbs the tension, thereby reducing the tension required for the saw blade 23. The reduced tension helps to reduce the stress of the saw blade 23 and reduce the risk of its breakage.

[0038] Therefore, when the wood saw machine with anti-band saw breakage in the utility model is used to cut wood, when the equipment is running, a flexible buffer belt 30 is clamped between the saw blade 23 and the saw wheel, so that the friction of the saw wheel is increased to reduce the tension and stress fatigue of the saw blade 23 during operation, thereby realizing flexible transmission of the saw blade 23 and reducing the risk of saw blade 23 breaking, thereby extending the service life of the saw blade 23.

[0039] It should be noted that the buffer belt 30 can be specifically made of a belt, a rubber belt, or a buffer belt 30 made of nylon or other synthetic fiber materials with appropriate friction and elasticity to ensure that it can provide additional friction while ensuring that the saw wheel can effectively drive the saw blade 23 to rotate. During specific assembly, the buffer belt 30 can be formed on the periphery of the saw wheel by gluing or integral molding. Of course, special treatment is also used to set a snap-in block or a snap-in strip structure on the contact surface between the buffer belt 30 and the saw wheel, and a snap-in groove and other structures are set on the periphery of the saw wheel so that the two can be snap-fitted and connected. The specific setting can be based on actual conditions.

[0040] In addition, the driving assembly 60 can use a driving motor. When assembled, the driving motor is connected to one of the saw wheels to drive one of the saw wheels to rotate. At this time, the other saw wheel can also rotate synchronously under the drive of the saw blade 23. Of course, two driving motors can also be provided, and two driving motors can simultaneously drive the two saw wheels to rotate synchronously.

[0041] Of course, in another embodiment, as a preference, the drive assembly 60 in this embodiment includes a drive motor and a transmission member 61 (such as gears, belts, chains, etc.), the power output end of the drive motor is connected to the transmission member 61, and then the transmission member 61 is connected to one of the saw wheels, so that when the drive motor is running, it can drive the transmission member 61 to rotate, thereby driving the saw wheel to rotate synchronously, and the torque of the drive motor can be transmitted to the saw wheel more smoothly through the transmission member 61, which can avoid torque fluctuations that may occur during direct drive, thereby improving the stability and accuracy of sawing.

[0042] In addition, the number of saw wheels can be set to three, four or more according to the height interval of the machine body 10, so that a plurality of processing intervals 13 are formed on the machine body 10. In this way, the linear transmission sections of the saw blade 23 located at the plurality of processing intervals 13 can be formed into a plurality of saw blade processing sections 231, so that a plurality of workpieces can be processed synchronously in the plurality of processing intervals 13 at the same time, thereby improving the overall processing speed.

[0043] Furthermore, a plurality of tooth grooves 24 are provided on both saw wheels, and the plurality of tooth grooves 24 are extended along the circumference of the saw wheels, and every two adjacent tooth grooves 24 are spaced apart and filled with glue, and the buffer belt 30 is glued and connected to the plurality of tooth grooves 24 .

[0044] Specifically, during assembly, glue can be filled in multiple tooth grooves 24. Since the tooth grooves 24 are extended along the circumference of the gear and are spaced apart from each other, the glue can be evenly distributed on the periphery of the saw wheel through the design of the tooth grooves 24. In this way, after the glue is initially solidified, the buffer belt 30 is sleeved onto the wheel surface of the saw wheel so that the buffer belt 30 can be stably glued to the wheel surface of the saw wheel, thereby providing stable support for the flexible buffer belt 30 and making the structure more stable.

[0045] Furthermore, mounting grooves 12 are provided at the top and bottom of the body 10. The two saw wheels include a driving wheel 21 and a driven wheel 22. During assembly, the driving wheel 21 is installed in the mounting groove 12 at the bottom of the body 10 through the first rotating shaft 211 and is connected to the driving assembly 60, while the driven wheel 22 is installed in the mounting groove 12 at the top of the body 10 through the second rotating shaft 221.

[0046] Specifically, after the driving wheel 21 and the driven wheel 22 are respectively installed in the two installation grooves 12, the inner wall of the installation groove 12 can effectively isolate external factors such as water, dust, and corrosive substances from falling into the outer surface of the driving wheel 21 and the driven wheel, preventing the driving wheel 21 from getting stuck and the driven wheel 22 from being affected by external factors, thereby extending the service life of the saw wheel and the entire equipment.

[0047] More specifically, during assembly, the driving wheel 21 can be rotatably installed in the mounting groove 12 through the first rotating shaft 211, and the driven wheel 22 can be installed in another mounting groove 12 through the second rotating shaft 221, wherein the first rotating shaft 211 can extend through the mounting groove 12 to the driving assembly 60 and be connected to the driving assembly 60, so that the driving assembly 60 can drive the driving wheel 21 to rotate, thereby driving the saw blade 23 and the driven wheel 22 to rotate synchronously.

[0048] In addition, cover plates 14 are provided at the upper and lower ends of the body 10. The two cover plates 14 can respectively cover the mounting groove 12 after the driving wheel 21 and the driven wheel 22 are assembled into the mounting groove 12 to further block external water, dust, etc. and prevent the saw wheel from being affected by external factors.

[0049] It should be noted that through holes can be respectively set at the two ends of the two installation grooves 12 that are close to each other, so that after the driving wheel 21 and the passive wheel 22 are installed in the installation grooves 12, the two ends of the saw blade 23 can respectively pass through the through holes and extend into the installation grooves 12 to be respectively connected to the driving wheel 21 and the passive wheel 22.

[0050] Furthermore, the utility model also includes a tensioning seat 70, which can be set on the top of the body 10 and installed on the side of the body 10 away from the mounting groove 12. During assembly, the second rotating shaft 221 is sequentially extended through the tensioning seat 70 to the passive wheel 22 to adjust the tension of the second rotating shaft 221 through the tensioning seat 70.

[0051] Specifically, after the equipment has been running for a period of time, the saw blade 23 sleeved on the passive wheel 22 may become loose due to friction, temperature changes or long-term stretching. At this time, since the other end of the second rotating shaft 221 is supported by the tensioning seat 70, the distance between the second rotating shaft 221 and the saw wheel can be adjusted by the tensioning seat 70 to ensure that the saw blade 23 is always tightly attached to the saw wheel, thereby accurately controlling the tension of the saw blade 23 to ensure that it works in the best condition and maintains stable cutting performance.

[0052] More specifically, elastic components 71 are provided on both sides of the tensioning seat 70, and one end of the elastic component 71 is respectively abutted against the tensioning seat 70, and the other end of the elastic component 71 is abutted against the body 10. When subjected to force, the elastic component 71 can provide an elastic stress to drive the tensioning seat 70 to move up and down along the height direction of the body 10.

[0053] Since one end of the second rotating shaft 221 for connecting with the passive wheel 22 is connected to the tensioning seat 70, and since the elastic components 71 on both sides of the tensioning seat 70 have a certain elastic stress, the passive wheel 22 will vibrate when the equipment is running, driving the second rotating shaft 221 to vibrate and causing the tensioning seat 70 to vibrate accordingly. At this time, since both ends of the tensioning seat 70 are abutted against the elastic components 71, the elastic components 71 are subjected to force due to their own elastic stress, allowing the tensioning seat 70 to float freely. In this way, when the wood feeding speed is too fast or the wood has knots, causing the saw blade 23 to impact or get stuck, since the tensioning seat 70 can float freely, the tightness of the saw blade 23 can be adjusted in real time, the saw blade 23 can be protected, and the risk of the saw blade 23 breaking can be reduced.

[0054] It should be noted that one end of the tensioning seat 70 can be connected to the body 10 through a connecting piece (such as a pin, a screw or a bolt, etc.), and the other end can be abutted against the body 10 through an elastic component 71 (such as a spring or an elastic sheet, etc.). Specifically, the elastic component 71 can be connected to the tensioning seat 70 and the body 10 respectively by welding or gluing.

[0055] Furthermore, the utility model also includes a support seat 80, which at least partially covers the tensioning seat 70 and can support the tensioning seat 70, one end of the elastic component 71 abuts against the tensioning seat 70, and the other end of the elastic component 71 abuts against the support seat 80.

[0056] Specifically, a support seat 80 can be further provided on the side of the body 10 away from the mounting groove 12. During assembly, the support seat 80 can partially cover the outer periphery of the tensioning seat 70 to support the tensioning seat 70. At this time, the other end of the elastic component 71 away from the tensioning seat 70 can extend into the support seat 80 and abut against the support seat 80, so as to cover the elastic component 71 through the support seat 80 to prevent the elastic component 71 from being exposed to the outside and being affected by water or dust caused by external factors, causing the elastic component 71 to be damaged or stuck and affecting the use of the entire structure.

[0057] Furthermore, a workpiece table 11 and a guide assembly 50 are provided at the processing interval 13. The guide assembly 50 is located above the workpiece table 11. The guide assembly 50 includes a fixed frame 51 and at least three clamping members 52. One end of the fixed frame 51 is connected to the support seat 80. At least three clamping members 52 are installed on the fixed frame 51, wherein two adjacent clamping members 52 are arranged at intervals and are used to clamp the saw blade 23, and the other clamping member 52 is against the saw blade 23.

[0058] Specifically, during assembly, a workpiece table 11 can be set at the processing interval 13, and the workpiece to be processed can be placed on the workpiece table 11 to facilitate subsequent processing of the workpiece. In addition, at least two clamping spaces are set, and the saw blade 23 can extend into the space between the two clamping members 52 when passing through the processing interval 13. In this way, the left and right sides of the saw blade 23 can be clamped by the two clamping members 52 to prevent it from shaking left and right when processing the workpiece, thereby affecting the processing accuracy.

[0059] In addition, another clamping member 52 can be pressed against the side of the saw blade 23 away from its processing end. In this way, the non-processing side of the saw blade 23 can be pressed against by the clamping member 52, reducing the risk of affecting the processing accuracy due to shaking during the processing, thereby improving the stability of the entire structure.

[0060] Furthermore, a mounting plate 53 is provided on the fixing frame 51, and a slide groove 531 is provided on the mounting plate 53, and each two adjacent clamping members 52 are installed in the slide groove 531 through a sliding rod and slidingly cooperate with the slide groove 531, so that the two clamping members 52 can be driven to move closer to or away from the saw blade 23 by sliding the sliding rod to lock or release the saw blade 23.

[0061] Specifically, since the saw blade 23 may relax due to friction, temperature changes or long-term stretching after operation, the distance between it and the two clamping members 52 becomes larger and larger, making it impossible for the clamping members 52 to clamp the saw blade 23, thereby affecting its use. Therefore, by passing the clamping member 52 through the sliding rod in the sliding groove 531, the clamping member 52 can adjust the distance between it and the saw blade 23 in real time by sliding the sliding rod, ensuring that the clamping member 52 can always lock the saw blade 23 to prevent it from shaking, and can also adjust the tightness of the saw blade 23 in real time to ensure the tension of the saw blade 23, protect the saw blade 23, and reduce the risk of its breakage; similarly, when the saw blade 23 is clamped too tightly or needs to be replaced and repaired, the sliding clamping member 52 can loosen the saw blade 23 to facilitate later maintenance.

[0062] It should be noted that the clamping member 52 can be a limiting member such as a bolt or a nut and can be slidably inserted into the sliding groove 531 through a sliding rod (such as a screw rod or a connecting rod, etc.).

[0063] Furthermore, bearing seats 40 are provided in the driving wheel 21 and the driven wheel 22. During assembly, the first rotating shaft 211 and the second rotating shaft 221 can be pivoted to the two bearing seats 40 respectively, so that the bearing seats 40 provide stable support and positioning for the first rotating shaft 211 and the second rotating shaft 221, so that the rotating shaft can rotate accurately at a predetermined position, thereby improving the stability and accuracy of the entire structure.

[0064] In addition, the bearings in the bearing seat 40 can effectively reduce the friction between the first rotating shaft 211 and the second rotating shaft 221 and the two saw wheels. This friction-reducing design not only allows the rotating shaft to rotate more smoothly, but also extends the service life of the rotating shaft and the bearings.

[0065] Preferably, the bearing seat 40 can be a sliding bearing seat or a rolling bearing seat, etc., and the bearing seat 40 in this embodiment is a ball bearing.

[0066] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
