Description

Technical Field

[0001] This invention relates to the field of wood cutting technology, specifically to a band saw machine tool for wood processing. Background Technology

[0002] Band saws are core equipment in wood processing. They rely on the continuous cyclical motion of an endless band saw blade to complete sawing, resulting in narrow kerfs and high yield. They are widely used in log cutting and board splitting. Among them, large band saws (carriage band saws) are used for log splitting, sawing large round logs into boards or square timber, and are suitable for large-scale operations in lumber mills.

[0003] When cutting logs, large band saws (carriage-mounted band saws) typically move the logs along the machine tool, cutting them with saw blades during the movement. However, due to the logs' length, the portion cut by the saw blade (but not completely severed) tends to sag. To prevent this, workers usually need to hold the cut logs, which is labor-intensive and potentially dangerous. Furthermore, the cut boards require manual assistance to push them onto a conveyor mechanism, which then transfers them to the next processing station. Manually moving the boards onto the conveyor is labor-intensive and can damage them, leading to resource waste. To address these issues, a new type of band saw for wood processing is proposed. Summary of the Invention

[0004] To achieve the above objectives, a band saw machine tool for wood processing includes a saw blade and a first guide rail arranged at intervals, and further includes: The machine tool is slidably mounted on the top of the first guide rail so that the machine tool can move along the length of the first guide rail. A fixing member is fixedly mounted on the front of the machine tool, and a plate is fixedly mounted on the front of the fixing member. A channel is formed between the plate and the machine tool through the fixing member. The saw blade is set in the channel. The top of the plate and the top of the machine tool are on the same horizontal plane. A conveying mechanism is arranged at intervals on the side of the plate away from the machine tool. An auxiliary mechanism, spaced apart on the side of the board away from the machine tool, is used to place the cut wood panels onto the conveying mechanism. The top of the machine tool has spaced-apart limiting mechanisms, and the side of the machine tool away from the board has a drive mechanism for moving the multiple limiting mechanisms as a whole. The limiting mechanisms cooperate with the auxiliary mechanism to position the wood panels for continuous reciprocating cutting. The auxiliary mechanism includes: The hinge frame is fixedly located on the side of the plate away from the machine tool. The side wall of the hinge frame is rotatably equipped with a hinge shaft. The side wall of the hinge shaft located inside the hinge frame is fixedly fitted with a hinge component. The top of the hinge component is fixedly equipped with a stop. The hinge shafts of the spaced auxiliary mechanisms are connected end to end and are all fixedly connected, and rotate synchronously with the stop of the spaced auxiliary mechanisms.

[0005] Furthermore, the auxiliary mechanism also includes: The first groove is formed on the side of the stop near the machine tool. The upper and lower ends of the inner wall of the first groove are provided with first through slots. The inner wall of the first through slot is fitted with a first baffle. The side wall of the first baffle is fixedly provided with a second baffle. The second baffle and the first baffle can move horizontally along the first groove and the first through slot respectively. The side of the second baffle near the first baffle is fixedly provided with a position sensor. The first servo motor is fixedly mounted on the side of the stop away from the second baffle. The output shaft of the first servo motor is fixedly provided with a first threaded rod extending into the first groove through a coupling. The first threaded rod is threaded to a first threaded tube on the side wall of one end of the first threaded rod located in the first groove. The first threaded tube is fixedly connected to the second baffle, and the first threaded rod is rotatably connected to the stop.

[0006] Furthermore, the auxiliary mechanism also includes: The second groove is formed at the top of the plate. The bottom of the inner wall of the second groove is formed with a third groove. The inner walls of the third groove and the second groove are respectively fitted with a fourth baffle and a third baffle. The side wall length of the third baffle is less than the side wall length of the fourth baffle. The bottom of the inner wall of the third groove is fixedly provided with first springs arranged at intervals. The top of the first spring is fixedly connected to the bottom of the fourth baffle. The support plate is fixedly installed on the side of the stop near the machine tool and extends into the channel. The support plate and the third stop are positioned correspondingly so that the support plate can press the third stop when it rotates to a horizontal position.

[0007] Furthermore, a first mounting groove is provided on the top of the plate, and when the support plate is in a horizontal state, the top of the support plate is located in the first mounting groove; The plate body has a second mounting groove on the side away from the machine tool, and the hinge frame is installed in the second mounting groove; The top of the board body on the side away from the channel has an inclined surface, so that the wood tends to flip towards the stop.

[0008] Furthermore, the limiting mechanism includes: A movable groove is formed on the top of the machine tool and extends to the side of the machine tool near the plate. The bottom inner wall of the movable groove is fixed with a second guide rail arranged at intervals, and a limit seat is slidably provided on the top of the second guide rail. A circular groove is formed on the top of the limiting seat. The inner walls on both sides of the circular groove are respectively provided with a sliding groove and a guide groove. The inner walls of the circular groove, the sliding groove and the guide groove are respectively fitted with a second threaded tube, a slider and a guide block arranged at intervals, and the second threaded tube at the same horizontal position is fixedly connected to the slider and the guide block.

[0009] Furthermore, the limiting mechanism also includes: The second servo motor is fixedly mounted on the top of the limit seat. The output shaft of the second servo motor is fixedly mounted with a second threaded rod via a coupling. The second threaded rod is a bidirectional screw. The second threaded rod is threadedly connected to the second threaded pipe and rotatably connected to the limit seat. Both guide blocks are fixedly mounted with a chuck on the side away from the second threaded pipe. The chucks are both designed in a bent shape and are arranged facing each other.

[0010] Furthermore, the conveying mechanism includes: The fixed seat is located on the side of the plate away from the machine tool and outside the first guide rail. The top of the fixed seat is rotatably equipped with spaced conveying rollers. The conveying rollers are arranged parallel to the length of the first guide rail. The spaced conveying mechanisms and spaced auxiliary mechanisms are staggered to leave space for the stop seat to rotate between two adjacent conveying mechanisms.

[0011] Furthermore, the drive mechanism includes: A mounting plate is fixedly installed on the side of the machine tool away from the plate body. The side wall of the mounting plate is fixedly fitted with spaced electric push rods. The telescopic shaft of the electric push rod is fixedly fitted with a connecting plate. The connecting plate is fixedly connected to the spaced limit seats to synchronously drive the spaced limit seats to move along the second guide rail.

[0012] Furthermore, the bottom of the plate is slidably connected to the first guide rail to support the plate. The movable grooves arranged at intervals are all connected to the channel, and the channel is located in the section between the movable groove closest to the fixing member and the fixing member, which leaves space for placing the saw blade.

[0013] Furthermore, both sides of the saw blade are provided with spaced-apart conveying mechanisms, which are used to convey the cut wood boards when the wood is being cut back and forth. The conveying mechanisms on both sides of the saw blade convey the cut wood boards in the same or opposite directions.

[0014] This invention provides a band saw machine tool for wood processing. Compared with the prior art, it has the following advantages: 1. This invention uses an auxiliary mechanism and a limiting mechanism to limit the wood during the cutting process, eliminating the need for workers to hold the cut part of the saw blade, reducing manual operation and avoiding injury to workers, thus reducing safety hazards. It also facilitates the automatic transfer of the cut wood boards to the conveyor rollers, eliminating the need for manual handling of the cut wood boards, reducing the intensity of manual operation, and improving the actual wood cutting efficiency.

[0015] 2. The present invention facilitates the automatic transport of wood onto the conveyor rollers through an auxiliary mechanism, and also facilitates the positioning of uncut wood after one cutting, preventing slippage when the wood is half-cut. Compared with the traditional method, it does not require flipping the wood after it is half-cut before cutting again. The operation is simple, the cutting efficiency is improved, and the center position of the wood can be better preserved, thereby obtaining more boards with larger areas and improving the utilization rate of wood.

[0016] 3. This invention cuts wood by having the saw blade cut within the channel, which facilitates the auxiliary mechanism to limit the wood while also enabling the wood to be cut during the reciprocating movement of the machine tool and the wood. Compared with the traditional method, it avoids the problem of the machine tool running empty when resetting, and can automatically place the cut wood board on the conveyor roller, thus improving the cutting efficiency.

[0017] 4. This invention improves the stability of the wood board as it rotates with the stop and the second stop by having a support plate support it from the bottom of the cut wood board. Furthermore, it can support the cut wood board when cutting at different locations, expanding its applicability. The auxiliary mechanism allows for adjustment of the position of the wood block, facilitating the adjustment of the thickness of the cut wood board according to actual needs. Furthermore, increasing the support plate increases the area of ​​the wood board it supports, making it easier to support thicker wood boards and improving support stability. This facilitates the subsequent flipping of the wood board onto the top of the conveyor rollers. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figures 1-5 and Figure 12 A band saw machine tool for wood processing includes a saw blade 4 and a first guide rail 1 arranged at intervals, and further includes: Machine tool 2 is slidably mounted on the top of the first guide rail 1 so that machine tool 2 can move along the length direction of the first guide rail 1. A fixing member 9 is fixedly mounted on the front of the machine tool 2, and a plate 5 is fixedly mounted on the front of the fixing member 9. A channel 10 is formed between the plate 5 and the machine tool 2 through the fixing member 9. A saw 4 is set in the channel 10. The top of the plate 5 and the top of the machine tool 2 are on the same horizontal plane. A conveying mechanism 6 is arranged at intervals on the side of the plate 5 away from the machine tool 2. Auxiliary mechanism 7 is spaced apart on the side of plate 5 away from machine tool 2 to place the cut wood board onto conveying mechanism 6. Limiting mechanisms 3 are spaced apart on the top of machine tool 2, and a driving mechanism 8 is provided on the side of machine tool 2 away from plate 5 to drive the multiple limiting mechanisms 3 to move as a whole. The limiting mechanisms 3 cooperate with auxiliary mechanism 7 to position the wood board for continuous reciprocating cutting. Auxiliary mechanism 7 includes: The hinge frame 795 is fixedly installed on the side of the plate 5 away from the machine tool 2. The side wall of the hinge frame 795 is rotatably provided with a hinge shaft 794. The side wall of the hinge shaft 794 located inside the hinge frame 795 is fixedly sleeved with a hinge member 793. The top of the hinge member 793 is fixedly provided with a stop seat 71. The hinge shafts 794 of the spaced auxiliary mechanisms 7 are connected end to end and are all fixedly connected, and are synchronously driven to rotate synchronously with the stop seats 71 of the spaced auxiliary mechanisms 7.

[0022] In practice, the first servo motor 79 drives the first baffle 77 and the second baffle 78 to move along the first through groove 796 and the first groove 797 respectively, thereby adjusting the length of the second baffle 78 extending out of the stop seat 71, and adjusting the length of the second baffle 78 extending into the channel 10, thereby adjusting the position of the second baffle 78 against the wood, so as to adjust the cutting thickness of the wood according to actual needs.

[0023] After adjusting the cutting thickness of the wood, place the wood to be cut on the top of the machine tool 2. Then, push the connecting plate 83 towards the stop 71 by the electric push rod 82, so as to drive the spaced limit seats 31 towards the stop 71, thereby pushing the wood towards the stop 71, so that the wood is limited between the stop 71 and the second stop plate 78. Then, drive the two chucks 36 towards each other by the second servo motor 34, thereby limiting the wood from the top and bottom, ensuring the stability of the wood, and preventing the wood from shaking and shifting during cutting.

[0024] After the wood is fixed, the machine tool 2 moves along the first guide rail 1. During the movement, the end of the wood first contacts the saw blade 4, thereby cutting the wood along its length. During the cutting process, the second baffle 78 and the limiting seat 31 always squeeze and limit the wood, so that the operator does not need to hold the cut part of the saw blade 4 during the cutting process, reducing manual operation and avoiding injury to the operator, thus reducing safety hazards. After cutting, the electric push rod 82 continues to move the wood closer to the stop 71. At the same time, the external motor drives the hinge shaft 794 to rotate, thereby causing the stop 71 and the second baffle 78 to rotate closer to the conveying mechanism 6. During this process, under the action of the inclined plane 11, the cut wood board flips onto the second baffle 78 and is supported from the bottom by the support plate 72, thus falling onto the second baffle 78. As the second baffle 78 continues to rotate, it rotates between adjacent fixed seats 61, thereby placing the cut wood board on the conveying roller 62 for easy conveying. This eliminates the need for manual handling of the cut wood board onto the conveying roller 62, reducing manual operation and improving actual processing efficiency.

[0025] During the process of the second baffle 78 transferring the cut wood board onto the conveyor roller 62, that is, during the rotation of the second baffle 78, the support plate 72 is also rotated, causing the support plate 72 to rotate from its original horizontal state to a vertical or inclined state, so as to ensure that the cut wood board is placed on the conveyor roller 62, and release the obstruction of the third baffle 73. Under the action of the first spring, the third baffle 73 moves upward to the top of the plate 5, thereby blocking the uncut wood and preventing the wood from slipping. After the conveying mechanism 6 has conveyed the cut wood board, the second baffle 78 is rotated in the reverse direction to reset. During the reset process, the third baffle 73 is squeezed, causing it to overcome the elastic force of the first spring and move into the second groove 74. This limits the wood to the second baffle 78. The limiting seat 31 then squeezes the wood closer to the second baffle 78, further limiting the wood through the second baffle 78 and the limiting seat 31. Subsequently, the machine tool 2 moves in the reverse direction, cutting the wood again. This ensures that the wood is cut during the reciprocating movement of the machine tool 2, improving cutting efficiency. After cutting, the cut wood board is automatically placed on top of the conveying roller 62 on the other side of the saw blade 4, facilitating the conveying of the cut wood board and improving cutting efficiency. Through this reciprocating process, continuous cutting of wood is achieved, increasing the efficiency of wood cutting.

[0026] By causing the hinge 793 and hinge shaft 794 to drive the stop 71 to deflect from the bottom of the stop 71, the cut wood board is facilitated to deflect onto the second stop 78 and the stop 71. This avoids the small gap between the cut wood board and the uncut wood affecting the deflection of the wood board, and allows the second stop 78 to limit the wood along most of the side wall of the stop 71, improving the stability of limiting the wood and supporting the wood board.

[0027] By fixing the hinge shafts 794 of multiple auxiliary mechanisms 7 end to end, and driving the end hinge shafts 794 to rotate through an external motor, it is easy to synchronously drive the hinge shafts 794 of multiple auxiliary mechanisms 7 to rotate, which is convenient for actual operation. The external motor that drives the hinge shafts 794 to rotate is not shown in the figure. This is the prior art and will not be described in detail here.

[0028] This invention uses the auxiliary mechanism 7 and the limiting mechanism 3 to limit the wood during the cutting process, eliminating the need for workers to hold the cut part of the saw blade 4 during the cutting process, reducing manual operation, avoiding injury to workers, reducing safety hazards, and facilitating the automatic transfer of the cut wood boards to the conveyor roller 62. This eliminates the need for manual handling of the cut wood boards, reducing the intensity of manual operation and improving the actual wood cutting efficiency.

[0029] The present invention facilitates the automatic transport of wood onto the conveyor roller 62 through the auxiliary mechanism 7, and also facilitates the positioning of uncut wood after one cutting, preventing the wood from slipping when it is half-cut. Compared with the traditional method, it does not require the wood to be flipped over after being half-cut before cutting. The operation is simple, the cutting efficiency is improved, and the center position of the wood can be better preserved, thereby obtaining more boards with larger areas and improving the utilization rate of wood.

[0030] This invention allows the saw blade 4 to cut the wood within the channel 10, which facilitates the auxiliary mechanism 7 to limit the wood while also enabling the wood to be cut during the reciprocating movement of the machine tool 2 and the wood. Compared with the traditional method, it avoids the problem of the machine tool 2 running empty when resetting, and can automatically place the cut wood board on the conveyor roller 62, thus improving the cutting efficiency.

[0031] In this invention, the driving device that drives the machine tool 2 to move along the first guide rail 1 is existing technology and is not shown in the figure. The saw blade 4 usually cuts the wood by reciprocating vertical movement. The overall device of the saw blade 4 is not shown in the figure. This is all existing technology and will not be described in detail here. It should be noted that when the conveying mechanisms 6 on both sides of the saw blade 4 convey the cut wood in the same direction, there should be space between the saw blade 4 and the device on which the saw blade 4 is installed to install the conveying mechanism 6, or the distance between the conveying mechanisms 6 on both sides of the saw blade 4 should be much smaller than the length of the wood to be cut, so as to ensure the normal conveying of the wood.

[0032] Please see Figures 7-13 The auxiliary mechanism 7 also includes: A first groove 797 is formed on the side of the stop 71 near the machine tool 2. A first through groove 796 is formed on the upper end and the lower end of the inner wall of the first groove 797. A first baffle 77 is fitted on the inner wall of the first through groove 796. A second baffle 78 is fixedly provided on the side wall of the first baffle 77. The second baffle 78 and the first baffle 77 can move horizontally along the first groove 797 and the first through groove 796 respectively. A position sensor 791 is fixedly provided on the side of the second baffle 78 near the first baffle 77. The first servo motor 79 is fixedly mounted on the side of the stop 71 away from the second baffle 78. The output shaft of the first servo motor 79 is fixedly provided with a first threaded rod 798 extending into the first groove 797 via a coupling. The first threaded rod 798 is threaded to a first threaded tube 792 on one end of its side wall located in the first groove 797. The first threaded tube 792 is fixedly connected to the second baffle 78, and the first threaded rod 798 is rotatably connected to the stop 71.

[0033] In practical implementation, the first servo motor 79 is activated, driving the first threaded rod 798 to rotate. The first threaded rod 798 then drives the second baffle 78 to move under the limiting conditions of the first baffle 77 and the first through groove 796, thereby adjusting the length of the second baffle 78 extending into the channel 10 to adjust its position against the wood, thus facilitating the adjustment of the thickness of the cut wood board according to actual needs. Furthermore, by moving the second baffle 78 driven by the first servo motor 79, after the wood cutting is completed, the second baffle 78 is moved in the opposite direction, causing the limiting mechanism 3 to push the wood closer to the stop 71, increasing the area that the support plate 72 can support. This facilitates support for thicker wood boards, improves the stability of the support, and facilitates the subsequent flipping of the wood board onto the top of the conveyor roller 62.

[0034] Auxiliary mechanism 7 also includes: The second groove 74 is opened at the top of the plate 5. The bottom of the inner wall of the second groove 74 is provided with a third groove 75. The inner walls of the third groove 75 and the second groove 74 are respectively fitted with a fourth baffle 76 and a third baffle 73. The side wall length of the third baffle 73 is less than the side wall length of the fourth baffle 76. The bottom of the inner wall of the third groove 75 is fixedly provided with first springs arranged at intervals. The top of the first springs is fixedly connected to the bottom of the fourth baffle 76. The support plate 72 is fixedly installed on the side of the stop 71 near the machine tool 2 and extends into the channel 10. The support plate 72 and the third stop 73 are positioned correspondingly so that the support plate 72 can press the third stop 73 when it rotates to a horizontal state.

[0035] In practical implementation, the first spring enables the third baffle 73 and the fourth baffle 76 to move vertically along the second groove 74 and the fourth groove, respectively. This allows the third baffle 73 to be pressed when the support plate 72 is horizontal, moving it into the second groove 74. This allows the support plate 72 to support the bottom of the cut wood board, improving the stability of the wood board as it rotates with the baffle 71 and the second baffle 78. Furthermore, since wood is typically cylindrical and cut first from the edge, resulting in a smaller diameter at the edge, the cut wood may slide down onto the top of the board 5 without bottom support. The support plate 72 supports the wood during rotation, ensuring support for the cut wood board at different cutting points.

[0036] After the support plate 72 rotates with the stop 71, it releases the restriction on the third stop 73 and the fourth stop 76. Under the action of the first spring, the third stop 73 moves to the top of the plate 5, thereby limiting the uncut wood and preventing the wood from slipping after it has been cut halfway and during the process of the stop 71 flipping to transfer the cut wood to the conveyor roller 62. Compared with the traditional method, it does not require flipping the wood after it has been cut halfway before cutting again, which is simpler to operate, improves cutting efficiency, and allows the center position of the wood to be better preserved, thus obtaining more boards with larger areas and improving the utilization rate of wood. In addition, after the wood boards are transferred to the conveyor roller 62 and the wood boards are conveyed, the stop 71 resets, which can squeeze the third stop 73 into the second groove 74 again without affecting the limitation of the second stop 78 and the stop 71 on the wood, and does not affect the limitation of the uncut wood next time.

[0037] The top of the plate 5 is provided with a first mounting groove 70. When the support plate 72 is in a horizontal state, the top of the support plate 72 is located in the first mounting groove 70. A second mounting groove 799 is provided on the side of the plate 5 away from the machine tool 2, and the hinge frame 795 is installed in the second mounting groove 799; The top of the side of the board 5 away from the channel 10 has a slope 11 so that the wood tends to flip towards the stop 71.

[0038] In practice, by placing the support plate 72 in the first mounting groove 70 when it is in a horizontal state, the movement of the wood towards the top of the board 5 is avoided. When the support plate 72 rotates with the stop 71, it can support the wood board from the bottom of the cut wood board, ensuring the stability of the flipped wood board.

[0039] By installing the hinge frame 795 in the second mounting slot 799, the distance between the stop 71 and the channel 10 in the vertical state is reduced, thereby reducing the length of wood placed on the top of the board 5, enabling the cutting of thinner wood, improving the applicable range of cutting, and without affecting the support of the board 5 for the wood, ensuring the stability of cutting.

[0040] By setting the inclined surface 11, when the limiting seat 31 pushes the wood and the cut wood board towards the baffle, the bottom of the wood board first lacks support and flips towards the baffle 71, thereby ensuring the stability of the wood board when it flips onto the second baffle 78.

[0041] Please see Figures 14-16 The limiting mechanism 3 includes: The movable groove 32 is opened on the top of the machine tool 2 and extends to the side of the machine tool 2 near the plate 5. The bottom inner wall of the movable groove 32 is fixedly provided with second guide rails 33 arranged at intervals, and the top of the second guide rails 33 is provided with a limiting seat 31. A circular groove is formed on the top of the limiting seat 31. The inner walls on both sides of the circular groove are respectively provided with a sliding groove 37 and a guide groove 39. The inner walls of the circular groove, the sliding groove 37 and the guide groove 39 are respectively fitted with a second threaded tube 38, a slider and a guide block arranged at intervals, and the second threaded tube 38 at the same horizontal position is fixedly connected to the slider and the guide block.

[0042] The limiting mechanism 3 also includes: The second servo motor 34 is fixedly mounted on the top of the limit seat 31. The output shaft of the second servo motor 34 is fixedly mounted with a second threaded rod 35 via a coupling. The second threaded rod 35 is a bidirectional screw. The second threaded rod 35 is threadedly connected to the second threaded tube 38. The second threaded rod 35 is rotatably connected to the limit seat 31. Each of the two guide blocks is fixedly mounted with a chuck 36 on the side away from the second threaded tube 38. The chucks 36 are both designed in a bent shape and are arranged facing each other.

[0043] In practice, the limiting seat 31 moves along the second guide rail 33 under the drive of the drive mechanism 8, so as to contact the wood through the side wall of the limiting seat 31 and push the wood to move towards the stop seat 71 to cooperate with the stop seat 71 and limit the wood.

[0044] The second servo motor 34 drives the second threaded rod 35 to rotate. Since the second threaded rod 35 is a bidirectional screw design, when the second servo motor 34 drives the second threaded rod 35 to rotate, it causes the two second threaded tubes 38 to move closer to each other under the limitation of the slide groove 37. As a result, the guide blocks move closer to each other along the guide groove 39, so as to drive the two clamping knives 36 to limit the wood from the top and bottom, thereby assisting in fixing the wood and improving the stability of the wood fixing. When the wood is cut more than halfway, limiting it from the bottom reduces the probability of wood slippage and improves the stability of the wood.

[0045] Please see Figure 6 The conveying mechanism 6 includes: The fixed seat 61 is located on the side of the plate 5 away from the machine tool 2 and on the outside of the first guide rail 1. The top of the fixed seat 61 is rotatably provided with a conveying roller 62 arranged at intervals. The conveying roller 62 is arranged parallel to the length direction of the first guide rail 1. The conveying mechanism 6 arranged at intervals and the auxiliary mechanism 7 arranged at intervals are staggered so that there is space between two adjacent conveying mechanisms 6 for the stop seat 71 to rotate.

[0046] In practice, after the cut wood boards are placed on the conveyor cylinder, the wood boards can be loosened by the rotation of the conveyor roller 62. During the actual conveying, the conveyor roller 62 can be driven to rotate by electric control for automatic conveying, or the wood boards can be manually pushed by the staff to convey them on the top of the conveyor cylinder. Those skilled in the art can design according to actual needs, and no limitation is made here.

[0047] Please see Figure 3 The drive mechanism 8 includes: Mounting plate 81 is fixedly mounted on the side of machine tool 2 away from plate body 5.

Connecting plate 83 is fixedly connected to spaced limit seats 31 to synchronously drive spaced limit seats 31 to move along second guide rail 33.

[0048] In practice, the connecting plate 83 is moved by the electric push rod 82, which in turn moves the spaced limit seats 31, so as to push the wood closer to the stop seat 71 and thus limit the wood.

[0049] The bottom of plate 5 is slidably connected to the first guide rail 1 to support plate 5 and ensure its stability. The spaced movable grooves 32 are all connected to the channel 10. The section of the channel 10 between the movable groove 32 closest to the fixing member 9 and the fixing member 9 has space for placing the saw blade 4 so that the wood can be cut again when the machine tool 2 is reset, so that cutting can be performed when the machine tool 2 drives the wood to move back and forth, thereby improving cutting efficiency.

[0050] Both sides of the saw blade 4 are provided with conveying mechanisms 6 arranged at intervals, which are used to transport the cut wood boards when the wood is reciprocated. The conveying mechanisms 6 on both sides of the saw blade 4 convey the cut wood boards in the same or opposite directions.

[0051] In practice, by setting up conveying mechanisms 6 at intervals on both sides of the saw blade 4, the cut wood boards can be conveyed during the reciprocating cutting of the wood, thereby improving the wood processing efficiency.
