Description

Technical Field

[0001] This invention relates to the field of wood processing equipment, and more specifically to a fully automatic wood cutting device. Background Technology

[0002] In log processing, trees in the forest are first felled, and branches are removed to create logs for processing. These logs are then processed into boards or timber using timber splitting equipment. The processed boards or timber are easy to transport and further process.

[0003] Some large logs weigh several tons or even more than ten tons and have a diameter of up to 2 meters. To facilitate cutting, the logs are fixed together for processing.

[0004] Existing wood cutting equipment has the following drawbacks: 1. The cutting process is complex. The existing cutting equipment has only one saw blade, which is mounted on a bracket that can rotate 90°. The rotation axis of the bracket is parallel to the forward direction. To cut a piece of wood, the saw blade needs to be adjusted to vertical first, and then cut along the length of the log. Then the saw blade needs to be adjusted to horizontal, and then cut along the length of the log again to obtain a piece of wood. 2. The clamping position of the log fixing device is too high, and the cutting efficiency is relatively low because the clamping device needs to be adjusted many times during the cutting process. At the same time, the work efficiency is also reduced because the position of the saw blade needs to be adjusted manually all the time. 4. Because wood is hard and has a high moisture content, the saw blade wears out quickly, and it is necessary to repeatedly remove the saw blade for tooth grinding during the cutting process; 5. During the log cutting process, sawdust is generated and falls onto the track. The sawdust is pressed onto the track by the guide wheels. If it is not cleaned in time, the accumulated sawdust will raise the position of the saw blade during the cutting process, which will increase the friction between the saw blade and the wood, causing the saw blade to overheat. This can affect the life of the saw blade or even cause a fire. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide a fully automatic wood cutting device that simplifies the cutting process, ensures stable log clamping, has a long service life for the saw blade and motor, and offers high processing efficiency.

[0006] According to one aspect of the present invention, a fully automatic wood cutting device is provided, comprising: a track assembly, a moving device, a cutting device, and a log fixing device. The moving device includes: an X-axis moving part, a Y-axis moving part, and a Z-axis moving part. The Y-axis moving part includes a gantry frame, a track cleaning device, and a drive device. The gantry frame is mounted on the track assembly, and the drive device drives the gantry frame to reciprocate on the track assembly. The gantry frame is equipped with a Z-axis moving part, and the X-axis moving part is mounted on the Z-axis moving part. The cutting device is mounted on the X-axis moving part. The log fixing device is installed in the middle of the track assembly, positioned between two tracks, to support and fix the log. The drive device drives the moving device to move along the track in the Y-direction to cut the log. The X-axis moving part moves the cutting device laterally perpendicular to the cutting direction, and the Z-axis moving part adjusts the vertical cutting position of the cutting device. The cutting device is equipped with one transverse saw blade and multiple longitudinal saw blades. By combining multiple saw blades, it is easy to cut multiple timber squares or boards in one movement, resulting in higher processing efficiency.

[0007] In some embodiments, the cutting device includes a first saw blade section and a second saw blade section. The first saw blade section rotates horizontally, and the second saw blade section rotates vertically. The first and second saw blade sections are arranged side-by-side along the cutting direction of the X-axis moving section, with the first saw blade section positioned at the front or rear end of the X-axis moving section's cutting direction. The horizontally rotating first saw blade section achieves horizontal cutting of the log, while the vertically rotating second saw blade section achieves vertical cutting. Multiple logs or boards can be cut in a single movement of the gantry frame, resulting in higher processing efficiency.

[0008] In some embodiments, the first saw blade section includes: a first servo motor, a first connecting shaft, and a first saw blade. The output end of the first servo motor is vertically arranged and fixed to the first connecting shaft via a coupling. The first saw blade is mounted on the bottom of the first connecting shaft. The first servo motor drives the first saw blade to rotate in the horizontal direction. A horizontal cut is completed by the rotation of the first saw blade.

[0009] In some implementations, the first saw blade has one.

[0010] In some embodiments, the second saw blade section includes: a second servo motor, a first drive wheel, a belt, a second connecting shaft, a spacer, and a second saw blade. The output end of the second servo motor is horizontally positioned, and the second connecting shaft is parallel to the output end of the second servo motor. One end of the second connecting shaft is connected to the Z-axis moving part, and the other end of the second connecting shaft is provided with the first drive wheel. The belt connects the output end of the second servo motor and the first drive wheel. Multiple second saw blades are provided, each sleeved on the second connecting shaft. Spacers are sleeved on the second connecting shaft, separating adjacent second saw blades. Multiple vertical cuts are achieved through the rotation of multiple second saw blades, improving processing efficiency. Furthermore, adjusting the distance between the second saw blades using spacers with different spacings ensures the processing needs of timber or boards of different specifications. At least two second saw blades are provided.

[0011] In some embodiments, the track assembly includes: a first track and a second track arranged in parallel, with the bottoms of the first track and the second track fixedly mounted on the ground.

[0012] In some embodiments, the Z-axis moving part includes: a moving beam, a fourth servo motor, a second transmission chain, and a third drive wheel. The two ends of the moving beam are connected to the inner side of the gantry through guide columns. The fourth servo motor is fixedly mounted on the gantry. The third drive wheel is connected to the output end of the fourth servo motor. The second transmission chain connects the third drive wheel and the moving beam. The third servo motor drives the moving beam to move up and down inside the gantry by rotating forward or in reverse. An X-axis moving part is installed on the moving beam. The X-axis moving part includes a fifth servo motor, a gear, a rack, a guide rod, a slider, and a mounting frame. A rack is fixedly installed at the bottom of the moving beam, and a guide rod is installed on one side of the moving beam. The slider is fitted onto the guide rod, and the back of the mounting frame is connected to the slider. The fifth servo motor is mounted on the mounting frame, and a gear is installed at the output end of the fifth servo motor. The gear meshes with the rack. The fifth servo motor drives the mounting frame to move left and right on the guide rod. A cutting device is installed on the mounting frame. A first saw blade is installed on one side of the moving beam, and a second saw blade is installed on the other side. The horizontal cutting height of the log is adjusted by moving the moving beam up and down using a fourth servo motor.

[0013] In some embodiments, the Y-axis moving part includes: a third servo motor, a first transmission chain, and a second drive wheel. The first and second tracks are fixed parallel to each other on the ground. The bottom of the gantry frame has grooved guide wheels connected to the tops of the first and second tracks. The output end of the third servo motor is connected to the second drive wheel. The first transmission chain is connected to the first track and the gantry frame via several transition wheels. The first transmission chain meshes with the second drive wheel. The third servo motor rotates forward or reverse to drive the gantry frame to move back and forth on the first and second tracks. The movement of the gantry frame on the first and second tracks by the third servo motor facilitates the movement of the first and second saw blades along the axial direction of the log to complete the cutting.

[0014] In some embodiments, the gantry frame is equipped with a track cleaning device, which includes a scraper assembly, a blower, and a pipe. The blower is installed at the top of the gantry frame, and the pipe is integrated inside the gantry frame. The air outlet of the pipe is located at the bottom of the gantry frame, directly above the first and second tracks. The scraper assembly includes a scraper seat, a scraper, and a top cover. Multiple scraper seats are provided and respectively installed at both ends of the bottom end beam of the gantry frame. The scraper is inserted into a groove provided in the scraper seat, and the top cover confines the scraper within the scraper seat. The track cleaning device facilitates the cleaning of sawdust that has fallen onto the first and second tracks, preventing saw blade undulation and thus avoiding saw blade bending or breakage. Furthermore, the weight of the scraper and its contact with the tracks further remove the sawdust from the tracks.

[0015] In some embodiments, the log fixing device includes: a base assembly, a first fixing component and a second fixing component, wherein the first fixing component and the second fixing component are mounted on the top of the base assembly, and the first fixing component and the second fixing component move independently toward the center of the base assembly; The first and second fixing components move to form a "V"-shaped contact with the log, thereby fixing the log in place. The overall height is low and the fixing is stable, making it easy for the saw blade to cut.

[0016] In some embodiments, the base assembly includes: a first support foot, a second support foot, a support rack, and a mounting beam. The first support foot is fixedly mounted on one side of the bottom of the mounting beam, and the second support foot is fixedly mounted on the other side of the bottom of the mounting beam. The support rack is fixedly mounted on both sides of the mounting beam, and a first fixing component and a second fixing component are mounted on the top of the mounting beam. The mounting beam provides mounting positions for the first fixing component and the second fixing component.

[0017] In some embodiments, the first fixing component includes a swing arm, a support rack, and a sliding seat. The rear end of the sliding seat is hinged to the front end of the swing arm via a first pivot, and the middle of the swing arm is hinged to the top of the support rack via a second pivot. The bottom of the support rack engages with the support rack. Lifting the end of the swing arm away from the sliding seat causes the bottom of the support rack to move and engage on the support rack. Pressing the end of the swing arm away from the sliding seat causes the sliding seat to move towards the center of the mounting beam. By moving the sliding seat towards the bottom of the log through the swing arm, the log is supported and fixed. By engaging the bottom of the support rack with the support rack, the lever-like compression of the swing arm pushes the sliding seat a short distance to fix the bottom of the log. This method is simple, reliable, and labor-saving.

[0018] In some embodiments, the front end of the sliding seat is a sharp triangle, and several limiting teeth are provided on the contact surface between the sliding seat and the log. The limiting teeth increase the friction with the log, thereby limiting the position of the log.

[0019] In some embodiments, the support rack has two sets symmetrically installed on both sides of the mounting beam; The support rack is provided in two sets. The support rack is mounted on both sides of the mounting beam via the second rotating shaft and engages with the support rack. The sliding seats are provided in two sets, and the middle of the sliding seats are connected by a fixed plate, which slides on the top of the mounting beam. The swing arm is provided in two sets, with the end of the swing arm away from the first rotating shaft fixedly connected by a pressure rod. By setting two sets of support racks, support pinions, sliding seats and swing arms, it is convenient to install on the crossbeam and also convenient for the sliding seats to slide downwards on the log to support the log.

[0020] In some embodiments, the structure of the second fixing component is the same as that of the first fixing component; The first and second fixing components are vertically symmetrically arranged around the center of the mounting beam. By moving the first and second fixing components towards the center of the beam, the two sides of the log are fixed, and the resulting "V"-shaped contact surface makes it more stable and reliable.

[0021] The control method of the fully automatic wood cutting equipment includes a control console that is electrically connected to the Y-axis moving part, X-axis moving part, Z-axis moving part, first saw blade part and second saw blade part, and receives data feedback from the Y-axis moving part, X-axis moving part, Z-axis moving part, first saw blade part and second saw blade part; The control method includes the following steps: S1. Log installation: Hoist the logs onto the two fixed devices for securing them. S2. Adjust the spacing between the second saw blades according to the customer's requirements for the timber. S3. Set parameters: set the quantity of timber, timber width, timber height, X-axis movement speed, Y-axis movement speed, Z-axis movement speed, Y-axis movement thrust, and set the rotation speed of the first and second saw blade sections. S4. Start the track cleaning device, and the air outlet of the pipeline will continuously blow the first and second tracks. S5. Start the invention. The Y-axis moving part, X-axis moving part and Z-axis moving part drive the first saw blade part and the second saw blade part to set the first coordinate A. Then the first saw blade part and the second saw blade part operate. The first saw blade and the second saw blade rotate at a set speed. S6, Signal Feedback: The first and second servo motors feed back their speed signals to the control console every 10-20ms. S7. Movement speed control: After receiving the speed signals of the first servo motor and the second servo motor, the control console adjusts the speed of the third servo motor according to the preset value, thereby controlling the movement speed of the gantry frame towards the second coordinate B on the first and second tracks. S8. After completing a single cut, the Y-axis moving part, X-axis moving part and Z-axis moving part are driven to move to the first saw blade part and the second saw blade part to the set second coordinate B. The first saw blade part and the second saw blade part complete a single cut on the log axis. The worker removes the cut log from the side away from the control console. S9. Movement: The Y-axis moving part, X-axis moving part, and Z-axis moving part are driven to move to the first saw blade part and the second saw blade part to the set third coordinate C. S10, Reverse cutting: The Y-axis moving part, X-axis moving part and Z-axis moving part drive the first saw blade part and the second saw blade part to move and cut towards the set fourth coordinate D. S11, Signal feedback: The first servo motor and the second servo motor feed back their speed signals to the control console every 10-20ms. S12, Movement speed control: After receiving the speed signals of the first servo motor and the second servo motor, the control console adjusts the speed of the third servo motor according to the preset value, and then controls the movement speed of the gantry crane towards the fourth coordinate D on the first and second tracks. S13. After completing the return cut, the Y-axis moving part, X-axis moving part and Z-axis moving part are driven to move to the first saw blade part and the second saw blade part to the set fourth coordinate D. The first saw blade part and the second saw blade part complete the axial return cut of the log. The worker removes the cut log from the side away from the control console. S14. Once one layer is cut, move to the next layer and repeat steps S5-S13 until the entire log is cut.

[0022] In some implementations, the control of the moving speed in S7 and S12 follows the following principles: Assumptions: The preset speed of the first servo motor is H revolutions per minute, and the preset speed of the second servo motor is L revolutions per minute; The console receives the actual speed of the first servo motor as M revolutions per minute, and the console receives the actual speed of the second servo motor as N revolutions per minute; When N≥80%L and M≥80%H, the control console does not adjust the speed of the third servo motor; When N < 80%L or M < 80%H, the control panel stops the third servo motor. When both the first and second servo motors exceed 80% of the preset speed, the third servo motor continues to rotate.

[0023] When the first and second saw blades encounter hard knots or scars during cutting, the speed of the first and second servo motors will inevitably decrease. If the cutting continues at the preset speed, the saw blades will get stuck at the knots or scars, causing the first and second servo motors that drive the saw blades to overload and burn out. By monitoring the speed of the first and second servo motors and adjusting the moving speed in time, the service life of the first and second servo motors and the switching efficiency can be guaranteed.

[0024] Compared with the prior art, the present invention has the advantages of simplified cutting process, stable log clamping, long service life of saw blade and motor, and high processing efficiency. The Y-axis moving part drives the gantry frame to move horizontally, facilitating the cutting of round logs. The X-axis moving part moves the cutting device perpendicular to the cutting direction, and the Z-axis moving part drives the cutting device to adjust the cutting distance. Multiple saw blades in the cutting device allow for the creation of multiple timber squares or boards in a single movement, increasing processing efficiency. The horizontally rotating first saw blade cuts the log horizontally, while the vertically rotating second saw blade cuts vertically. The gantry frame can complete multiple timber squares or boards in a single movement, further increasing efficiency. The rotation of the first saw blade completes at least one horizontal cut, while the rotation of multiple second saw blades completes multiple vertical cuts, improving processing efficiency. Adjusting the distance between the second saw blades with different spacing allows for the processing of timber squares or boards of different sizes. A fourth servo motor moves the moving beam up and down, adjusting the horizontal cutting height of the round log. A third servo motor moves the gantry frame along the first and second tracks, facilitating the movement of the first and second saw blades along the log. Axial movement completes the cutting; the track cleaning device easily blows away sawdust falling onto the first and second tracks, preventing saw blade undulation and thus avoiding saw blade bending or breakage; the independent movement of the first and second fixing components allows for convenient and stable fixation of the log, with a low overall height, facilitating saw blade cutting; the installation beam provides the installation position for the first and second fixing components; the swing arm drives the sliding seat to move towards the bottom of the log, thereby supporting and fixing the log, and the bottom of the support rack engages with the support rack, utilizing the lever-type mechanism of the swing arm. The compression mechanism pushes the sliding seat a short distance to the bottom of the log for fixation, which is simple, reliable, and labor-saving. The limiting teeth contact the log, increasing the friction and thus limiting the log's position. The toothed structure holds the log in place to prevent rotation. The two sets of support racks, support rods, sliding seats, and swing arms facilitate installation on the crossbeam and allow the sliding seat to slide downwards to support the log. The curved swing arms make it easier to press down. The first and second fixing components secure both sides of the log for greater stability and reliability. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0027] In the description of this invention, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the terms according to the specific circumstances.

[0028] like Figure 1As shown, the fully automatic wood cutting equipment of the present invention includes: a track assembly 10, a moving device 1, a cutting device 2, and a log fixing device 3. The moving device includes: an X-axis moving part 5, a Y-axis moving part 4, and a Z-axis moving part 6. The Y-axis moving part includes a gantry frame 7 and a drive device 9. The gantry frame 7 is mounted on the track assembly 10, and the drive device 9 drives the gantry frame 7 to reciprocate on the track assembly 10. The gantry frame 7 is equipped with the Z-axis moving part 6, the X-axis moving part 5 is mounted on the Z-axis moving part 6, and the cutting device 2 is mounted on the X-axis moving part 5. The log fixing device 3 is installed in the middle of the track assembly 10. The Y-axis moving part 4 drives the gantry frame 7 to move horizontally, facilitating the cutting of logs. The X-axis moving part 5 moves the cutting device 2 perpendicular to the cutting direction. The Z-axis moving part 6 drives the cutting device 2 to adjust the cutting distance. The cutting device 2 is equipped with multiple saw blades, which facilitates the cutting of multiple timber squares or boards in one movement, resulting in higher processing efficiency.

[0029] like Figure 2 As shown, the cutting device 2 includes a first saw blade section 21 and a second saw blade section 22. The first saw blade section 21 rotates horizontally, and the second saw blade section 22 rotates vertically. The first saw blade section 21 and the second saw blade section 22 are arranged side by side along the cutting direction of the Y-axis moving part 4, with the first saw blade section 21 located at the front or rear end of the Y-axis moving part 4 in the cutting direction. The horizontally rotating first saw blade section 21 achieves horizontal cutting of the log, while the vertically rotating second saw blade section 22 achieves vertical cutting of the log. The gantry frame 7 can complete the cutting of multiple logs or boards in one movement, resulting in higher processing efficiency.

[0030] In essence, the cutting path of the first saw blade 21 coincides with the cutting path of the second saw blade 22. However, the first saw blade 21 cuts horizontally, while the second saw blade 22 cuts vertically. In this way, a single cut can form a board or a piece of timber.

[0031] Typically, the first saw blade section 21 is located in front of the second saw blade section 22, that is, in front of the cutting direction. Simply put, the first saw blade 213 performs horizontal cutting first, followed by vertical cutting by multiple second saw blades 226. The advantage of doing this is that horizontal division is performed first, making subsequent vertical cutting easier and facilitating sawdust removal.

[0032] The first saw blade section 21 includes a first servo motor 211, a first connecting shaft 212, and a first saw blade 213. The output end of the first servo motor 211 is vertically arranged and fixed to the first connecting shaft 212 via a coupling. The first saw blade 213 is mounted on the bottom of the first connecting shaft 212, and the first servo motor 211 drives the first saw blade 213 to rotate in the horizontal direction. At least one first saw blade 213 is provided. The rotation of the first saw blade 213 can complete at least one horizontal cut.

[0033] The second saw blade section 22 includes: a second servo motor 221, a first drive wheel 222, a belt 223, a second connecting shaft 224, a spacer 225, and a second saw blade 226. The output end of the second servo motor 221 is horizontally positioned, and the second connecting shaft 224 is parallel to the output end of the second servo motor 221. One end of the second connecting shaft 224 is connected to the Z-axis moving part 6, and the other end of the second connecting shaft 224 is provided with the first drive wheel 222. The belt 223 connects the output end of the second servo motor 221 to the first drive wheel 222. Multiple second saw blades 226 are provided, and each second saw blade 226 is sleeved on the second connecting shaft 224. The spacer 225 is sleeved on the second connecting shaft 224, separating adjacent second saw blades 226. Multiple vertical cuts are completed by rotating multiple second saw blades 226, which improves processing efficiency. At the same time, adjusting the distance between the second saw blades 226 using spacers 225 with different spacings ensures the processing needs of timber or boards of different specifications.

[0034] like Figure 3 As shown, the Z-axis moving part 6 includes: a moving beam 61, a fourth servo motor 62, a second transmission chain 63, and a third drive wheel 64. The two ends of the moving beam 61 are connected to the inner side of the gantry frame 7 via guide columns. The fourth servo motor 62 is fixedly mounted on the gantry frame 7. The third drive wheel 64 is connected to the output end of the fourth servo motor 62. The second transmission chain 63 connects the third drive wheel 64 and the moving beam 61. The third servo motor 63 drives the moving beam 61 to move up and down reciprocally inside the gantry frame 7 by rotating forward or reverse. The adjustment of the horizontal cutting height of the log is achieved by moving the moving beam 61 up and down driven by the fourth servo motor 62.

[0035] An X-axis moving part 5 is installed on the moving beam 61. The X-axis moving part 5 includes a fifth servo motor 51, a gear 52, a rack 53, a guide rod 54, a slider 55, and a mounting frame 56. The rack 53 is fixedly installed at the bottom of the moving beam 61. The guide rod 54 is installed on one side of the moving beam 61, and the slider 55 is sleeved on the guide rod 54. The back of the mounting frame 56 is connected to the slider 55. The fifth servo motor 51 is mounted on the mounting frame 56, and the gear 52 is installed at the output end of the fifth servo motor 51. The gear 52 meshes with the rack 53. The fifth servo motor 51 drives the mounting frame 56 to reciprocate on the guide rod 54. A cutting device 2 is installed on the mounting frame 56. A first saw blade part 21 is installed on one side of the moving beam 61, and a second saw blade part 22 is installed on the other side of the moving beam 61. The guide rod 54 is perpendicular to the first track 41 and the second track 42. When the diameter of the log is large, the X-axis moving part 5 drives the cutting device 2 to cut the other side of the log at the same height.

[0036] In the specific implementation process, the fourth servo motor 62 is connected to the drive shaft through the reducer. The rotating shaft is installed on the gantry 7. The drive shaft and the reducer are connected through a coupling. Two third drive wheels 64 are set and located above the moving beam 61. Two sets of second transmission chains 63 are also set and connected to both ends of the moving beam 61 respectively. The simultaneous lifting and lowering of both ends realizes the smooth movement of the moving beam 61.

[0037] The track assembly 10 includes: a first track 41 and a second track 42 arranged in parallel, with the bottom of the first track 41 and the second track 42 fixedly installed on the ground.

[0038] The Y-axis moving part 4 includes a third servo motor 43, a first transmission chain 44, and a second drive wheel 45. A first track 41 and a second track 42 are fixed parallel to each other on the ground. The bottom of the gantry frame 7 is connected to the top of the first track 41 and the second track 42. The output end of the third servo motor 43 is connected to the second drive wheel 45. The first transmission chain 44 is connected to the first track 41 and the gantry frame 7 via several transition wheels. The first transmission chain 44 meshes with the second drive wheel 45. The third servo motor 43 drives the gantry frame 7 to reciprocate on the first track 41 and the second track 42 by rotating forward or reverse. The movement of the gantry frame 7 via the third servo motor 43 on the first track 41 and the second track 42 facilitates the movement of the first saw blade part 21 and the second saw blade part 22 along the axial direction of the log to complete the cutting.

[0039] In the specific implementation process, the third servo motor 43 is connected to the drive shaft through the reducer. The rotating shaft is installed on the gantry 7. The drive shaft and the reducer are connected through a coupling. Two second drive wheels 45 are set and located above the gantry 7. Two sets of first transmission chains 44 are also set and connected to the first track 41 and the second track 42 respectively. The two ends work simultaneously to realize the smooth movement of the gantry 7 on the first track 41 and the second track 42.

[0040] like Figure 4 As shown, the gantry frame 7 is equipped with a track cleaning device 8, which includes an air blower 81 and a pipe 82. The air blower 81 is installed on the top of the gantry frame 7, and the air outlet of the pipe 82 is located above the first track 41 and the second track 42. The track cleaning device 8 effectively sweeps away sawdust that falls onto the first track 41 and the second track 42, preventing the saw blade from undulating and thus bending or breaking.

[0041] like Figure 10 As shown, the track cleaning device 8 also includes a scraper assembly 83, which comprises a scraper seat 831, a scraper 832, and a top cover 833. Multiple scraper seats 831 are provided and respectively installed at both ends of the bottom end beam of the gantry frame 7. The scraper 832 is inserted into a groove provided within the scraper seat 831, and the top cover 833 confines the scraper 832 within the scraper seat 831. The scraper 832, by its own weight and contact with the track, removes the wood chips from the track. Thus, the scraping by the air blower 81 and the scraper 832 ensures that no wood chips remain on the first track 41 and the second track 42.

[0042] Pipe 82 can be a sealed corrugated pipe, with two sets of corrugated pipes simultaneously connected to the output end of the air blower 81. This requires additional fixing of pipe 82 to the gantry frame 7, which is simple but appears redundant. The optimal solution is to directly utilize the vertical square tube of the gantry frame 7 for pipe 82, resulting in a more compact structure. However, it is important to ensure a proper seal between the top of the square tube and the air blower 81, and to install a gradually narrowing air outlet at the bottom of the square tube. Multiple sets of pipe 82 can be installed as needed to facilitate timely cleaning of sawdust from the first track 41 and the second track 42.

[0043] like Figure 5 As shown, the existing log fixing device includes a base, two vertically fixed clamping rods on the base, and a vertical rod-shaped fixing rod on each clamping rod. One end of the fixing rod is sharp, and the other end of the fixing rod has a rotating wheel. The outer wall of the fixing rod has external threads, and the clamping rod has threaded holes that match the external threads on the outer wall of the fixing rod. The fixing rod and the clamping rod are threaded together, and the sharp end of the fixing rod is driven into the log by rotating the rotating wheel, thus fixing it from both sides. The clamping rods are either the same height or one is higher than the other to clamp and fix the log. The base also has a guide rail, on which the two clamping rods can slide and be fixed. However, the higher clamping rod has a higher minimum cutting plane, resulting in wasted wood that is not cut, and requiring multiple adjustments of the clamp if cutting is necessary. The lower clamping rod has a lower minimum cutting plane, making it difficult for the clamp to embed into the wood, and the clamp is difficult to fix, making it prone to loosening during processing.

[0044] like Figure 6As shown, the log fixing device 3 includes: a base assembly 31, a first fixing component 32 and a second fixing component 33. The first fixing component 32 and the second fixing component 33 are installed on the top of the base assembly 31. The first fixing component 32 and the second fixing component 33 can move independently toward the center of the base assembly 31. The log can be easily fixed by moving the first fixing component 32 and the second fixing component 33 inward or moving them separately. The fixation is stable and the overall height is low, which is convenient for saw blade cutting.

[0045] In actual use, at least two fixing devices 3 are required to work together. One fixing device 3 is placed on the thicker side of the log, and the other fixing device 3 is placed on the thinner end of the log. The log is fixed by the two sets of devices.

[0046] The base assembly 31 includes: a first support foot 311, a support rack 321, a second support foot 312, and a mounting beam 313. The first support foot 311 is fixedly mounted on one side of the bottom of the mounting beam 313, and the second support foot 312 is fixedly mounted on the other side of the bottom of the mounting beam 313. Four support racks 321 are fixedly mounted on both ends of the side of the mounting beam 313. A first fixing component 32 and a second fixing component 33 are placed on the top of the mounting beam 313. The mounting beam 313 provides mounting positions for the first fixing component 32 and the second fixing component 33.

[0047] like Figure 7 As shown, the first fixing component 32 includes: a swing arm 322, a support rack 323, and a sliding seat 324. The rear end of the sliding seat 324 is hinged to the front end of the swing arm 322 via a first rotating shaft 325. The middle of the swing arm 322 is hinged to the top of the support rack 323 via a second rotating shaft 326. The bottom of the support rack 323 is engaged with the support rack 321. When the end of the swing arm 322 away from the sliding seat 324 is lifted, the bottom of the support rack 323 moves and engages on the support rack 321. Pressing the swing arm 322 pushes the sliding seat 324 towards the middle position of the mounting beam 313 under the combined action of the swing arm 322, the support rack 323, and the support rack 321. The sliding seat 324 is moved towards the bottom of the log by the swing arm 322; the first fixing component 32 and the second fixing component 33 form a "V" shape with the contact surface of the log, thereby fixing the log; at the same time, the contact position between the sliding seat 324 and the log is provided with reverse teeth, which can effectively prevent the log from rotating; the bottom of the support toothed rod 323 is engaged with the support rack 321. The support rack 321 uses the lever-type compression of the swing arm 322 to push the sliding seat 324 a short distance towards the bottom of the log for fixing, which is simple, reliable and labor-saving.

[0048] like Figure 8As shown, during implementation: Pressing down on the end of the swing arm 322 causes the second pivot 326 to press against the mounting beam 313, serving as fulcrum 1. At the same time, the support rack 321 also serves as fulcrum 2. The first pivot 325 at the front end of the swing arm 322 also serves as support point 3. As the fixing components are subjected to force, fulcrum 1 is below the line connecting fulcrum 2 and fulcrum 3 and is in close contact with the beam 13, so it will not come loose. The second rotating shaft 326 pushes the first rotating shaft 325 and the sliding seat 324 towards the center of the mounting beam 313, which is below the log, before the first rotating shaft 325 and the sliding seat 324 slide on the mounting beam 313. After the sliding seat 324 contacts the log, the end of the swing arm 322 is lifted, and then the swing arm 322 rotates around the first rotating shaft 325. The second rotating shaft 326 and the support tooth 323 move upward, and the bottom of the support tooth 323 disengages from the original ratchet and falls into the next ratchet, pressing the end of the swing arm 322 again. The above steps are repeated to push the sliding seat 324 towards the bottom of the log. Of course, the upper teeth of the support rack 321 need to be inclined toward the center of the mounting beam 313, and when they engage with the teeth at the bottom of the support rack 323, they need to have the function of ratchet teeth to prevent the bottom of the support rack 321 from sliding away from the end of the round log.

[0049] like Figure 9 As shown, F represents the force transmitted from the weight of the log itself. The first pivot 325 serves as the first fulcrum, the point where the bottom of the supporting rack 323 is fixed to the supporting rack 321 serves as the second fulcrum, and the second pivot 326 serves as the third fulcrum. The second fulcrum is locked in the tooth groove, limiting its position; the third fulcrum is on the sliding seat 324 and cannot move downwards, only forwards or upwards. However, regardless of its forward or upward movement, it is held down by the log. The design considers that in a horizontal state, the first fulcrum is below the second and third fulcrums. Therefore, once subjected to force, the first fulcrum is only allowed to move downwards below the line connecting the second and third fulcrums. However, the downward movement of the first fulcrum will tightly press against the mounting beam 313, meaning the mounting beam 313 prevents the first fulcrum from moving further downwards. Therefore, because each fulcrum is constrained, the mechanism will not detach, achieving stable support. Only after the swing arm 322 is raised so that the bottom of the support rack 323 is disengaged from the support rack 321 can the various fulcrums be unrestricted.

[0050] The sliding seat 324 is a triangle with a sharp front end, and several limiting teeth 241 are provided on the contact surface between the sliding seat 324 and the log. The limiting teeth 241 increase the friction with the log and thus limit the position of the log.

[0051] The support rack 321 is provided in two sets, which are symmetrically installed on both sides of the mounting beam 313; The support rack 323 is provided in two sets. The support rack 323 is mounted on both sides of the mounting beam 313 via the second rotating shaft 326 and engages with the support rack 321. Two sets of sliding seats 324 are provided, and the middle of the sliding seats 324 are connected by a fixing plate 27, which slides on the top of the mounting beam 313. Two sets of swing arms 322 are provided, with one end of the swing arm 322 away from the first rotating shaft 325 fixedly connected by a pressure rod 28. By setting two sets of support racks 321, support racks 321, support pinions 323, sliding seats 324 and swing arms 322, it is convenient to set them on the mounting beam 313 and to facilitate the sliding seats 324 to slide downwards on the log to support the log.

[0052] During use: In the initial state: First adjust the position of the sliding seat 324 according to the diameter of the log, and ensure that the bottom of the support rack 323 is engaged with the ratchet of the support rack 321; Adjust the radial fixing device of the log at the other end as described above, and adjust the distance between the two fixing devices according to the length of the log; When the contact hoisting equipment places the logs onto the two log radial fixing devices, the front end of the sliding seat 324 has not yet come into contact with the logs. Pressing down on the swing arm 322 at one end of the first fixing component 32 causes the bottom of the support rack 323 to engage with the support rack 321. The support rack 321 uses the lever-type compression of the swing arm 322 to push the sliding seat 324 a small distance toward the bottom of the log to support and fix the log. Pressing down on the swing arm 322 at one end of the second fixing component 33 causes the bottom of the support rack 323 to engage with the support rack 321. The support rack 321 uses the lever-type compression of the swing arm 322 to push the sliding seat 324 a small distance toward the bottom of the log to support and fix the log. The same operation is performed on the radial fixing device of the thinner end of the log.

[0053] The structure of the second fixing component 33 is the same as that of the first fixing component 32; The first fixing component 32 and the second fixing component 33 are vertically symmetrically arranged around the center of the mounting beam 313. The first fixing component 32 and the second fixing component 33 secure both sides of the log, making it more stable and reliable.

[0054] During use: The structure of the second fixing component 33 is the same as that of the first fixing component 32; The first fixing component 32 and the second fixing component 33 are vertically symmetrically arranged around the center of the mounting beam 313. The two sides of the log are fixed by the first fixing component 32 and the second fixing component 33, making it more stable and reliable. According to the installation position of the log, the height of the first saw blade 213 is set and adjusted, and then the spacing between the second saw blades 226 is adjusted by using the spacer 225. The speed of the first servo motor 211 and the second servo motor 221 are set, and the moving speed of the Y-axis moving part 4 and the moving distance of the X-axis moving part 5 are set. Turn on the hair dryer; When the present invention is operated, the first saw blade 213 and the second saw blade 226 rotate, and the Y-axis moving part 4 drives the first saw blade 213 and the second saw blade 226 to move from one end of the log to the other end. First, the first saw blade 213 cuts the log horizontally. Then, as the Y-axis moving part 4 drives the gantry 7 to move, the second saw blade 226 cuts the log vertically. After the second saw blade 226 is completely separated from the log, the separated wood or board is removed from the other end. The X-axis moving part 5 moves to the other side; The Y-axis moving part 4 drives the first saw blade 213 and the second saw blade 226 to move towards the initial cutting end. First, the second saw blade 226 cuts the log vertically. Then, as the Y-axis moving part 4 drives the gantry 7 to move, the first saw blade 213 cuts the log horizontally. Once the first saw blade 213 is completely separated from the log, the separated timber or board is removed from the other end. The Z-axis moving part 6 moves downward and repeats the above cutting process until the log is cut. Z-axis moving part 6 moves upward to the initial position, X-axis moving part 5 moves horizontally to the initial position, and Y-axis moving part 4 drives the gantry 7 to move to the initial position; Close the invention, replace the wood according to the above steps, and cut it.

[0055] The control method of the fully automatic wood cutting equipment includes a control console, which is electrically connected to the Y-axis moving part 4, the X-axis moving part 5, the Z-axis moving part 6, the first saw blade part 21 and the second saw blade part 22, and receives data feedback from the Y-axis moving part 4, the X-axis moving part 5, the Z-axis moving part 6, the first saw blade part 21 and the second saw blade part 22. The control method includes the following steps: S1. Log installation: Hoist the logs onto the two fixing devices 3 for secure installation; S2. Adjust the spacing between the second saw blades 226 according to the customer's requirements for timber. S3. Set parameters: set the quantity of timber, timber width, timber height, Y-axis moving part 4 moving thrust, X-axis moving part 5 moving speed, Z-axis moving part 6 moving speed, position parameters and moving speed; set the rotation speed of the first saw blade part 21 and the second saw blade part 22. S4. Start the track cleaning device 8, and the air outlet of pipe 82 continuously blows the first track 41 and the second track 42. S5. Start the invention. The Y-axis moving part 4, the X-axis moving part 5 and the Z-axis moving part 6 drive the first saw blade part 21 and the second saw blade part 22 to set the first coordinate A. Then the first saw blade part 21 and the second saw blade part 22 operate. The first saw blade 213 and the second saw blade 226 rotate at a set speed. S6, Signal feedback: The first servo motor 211 and the second servo motor 221 feed back the speed signals of the first servo motor 211 and the second servo motor 221 to the control console every 10 seconds. S7. Movement speed control: After receiving the speed signals of the first servo motor 211 and the second servo motor 221, the control console adjusts the speed of the third servo motor 43 according to the preset value, thereby controlling the movement speed of the gantry 7 towards the second coordinate B on the first track 41 and the second track 43. S8. After completing a single cut, the Y-axis moving part 4, X-axis moving part 5 and Z-axis moving part 6 are driven to move to the first saw blade part 21 and the second saw blade part 22 to the set second coordinate B. The first saw blade part 21 and the second saw blade part 22 complete a single cut on the axial direction of the log. The worker removes the cut log from the side away from the control console. S9. Movement: The Y-axis moving part, X-axis moving part, and Z-axis moving part are driven to move to the first saw blade part and the second saw blade part to the set third coordinate C. S10, Reverse cutting: The Y-axis moving part, X-axis moving part and Z-axis moving part drive the first saw blade part and the second saw blade part to move and cut towards the set fourth coordinate D. S11, Signal feedback: The first servo motor 211 and the second servo motor 221 feed back the speed signals of the first servo motor 211 and the second servo motor 221 to the control console every 10 seconds. S12, Movement speed control: After receiving the speed signals of the first servo motor 211 and the second servo motor 221, the control console adjusts the speed of the third servo motor 43 according to the preset value, and then controls the movement speed of the gantry 7 towards the fourth coordinate D on the first track 41 and the second track 42. S13. After completing the return cut, the Y-axis moving part 4, X-axis moving part 5 and Z-axis moving part 6 are driven to move to the first saw blade part 21 and the second saw blade part 22 to the set fourth coordinate D. The first saw blade part 21 and the second saw blade part 22 complete the axial return cut of the log. The worker removes the cut log from the side away from the control console. S14. Once one layer is cut, move to the next layer and repeat steps S5-S13 until the entire log is cut.

[0056] In some implementations, the control of the moving speed in S7 and S12 follows the following principles: Assumptions: The preset speed of the first servo motor 211 is H revolutions per minute, and the preset speed of the second servo motor 221 is L revolutions per minute; The console receives the actual speed of the first servo motor 211 as M revolutions per minute, and the console receives the actual speed of the second servo motor 221 as N revolutions per minute; When N≥80%L and M≥80%H, the control console does not adjust the speed of the third servo motor 43; When N < 80%L or M < 80%H, the control panel stops the third servo motor 43. When both the first servo motor 211 and the second servo motor 221 exceed 80% of the preset speed, the third servo motor 43 continues to rotate.

[0057] When the first saw blade 213 and the second saw blade 226 encounter hard knots or scars during the cutting process, the speed of the first servo motor 211 and the second servo motor 221 will inevitably decrease. If the cutting is continued at the preset speed, the saw blade will get stuck at the knot or scar, causing the first servo motor 211 and the second servo motor 221 that drive the saw blade to overload and burn out. By monitoring the speed of the first servo motor 211 and the second servo motor 221, the moving speed is adjusted in time to ensure the service life and switching efficiency of the first servo motor 211 and the second servo motor 221.

[0058] The above descriptions are merely some embodiments of the present invention. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
