Description

Technical Field

[0001] This invention belongs to the field of wood cutting technology, specifically a wood sawing device and method for papermaking raw material processing. Background Technology

[0002] The core of wood papermaking is to first cut the logs into multiple sections, then make them into standard wood chips, and then make paper through pulping, papermaking, and post-processing. Cutting and chipping is a key step in the pretreatment of papermaking raw materials. In this step, sawing equipment is often used to cut the logs into multiple sections to facilitate the subsequent chipping process.

[0003] In existing technologies, wood cutting machines lack limiting structures, making log segments susceptible to lateral deviation and axial rolling due to the rotational force of the saw wheel during feeding. This results in uneven force on the saw wheel during cutting, leading to swaying or wear. In addition, since most wood cutting machines lack real-time monitoring sensors, problems such as excessive load caused by the saw wheel encountering knots cannot be predicted in advance. Workers can only rely on on-site observation based on experience to make judgments, and by the time the fault is discovered, some product loss has often already occurred.

[0004] Therefore, the present invention provides a wood sawing device and method for papermaking raw material processing. Summary of the Invention

[0017] A method for sawing wood for papermaking raw material processing, applicable to the aforementioned wood sawing apparatus for papermaking raw material processing, includes the following steps:

[0018] S1: The worker places the whole log section on the guide roller of the feed plate, starts motor two, and conveyor belt one and conveyor belt two start to drive. The log section is moved towards the saw wheel side by the clamp plate on conveyor belt one.

[0019] S2: After the log section slides to the bottom of the second conveyor belt, the claws that have disengaged from the arc plate slowly begin to retract. At the same time, after the guide rod disengages from the arc groove, the limit rod, under the elastic force of the second spring, drives the mounting frame and the claws to slide towards the log section until the claws are in contact with the surface of the log section, thus completing the clamping action.

[0020] S3: After the log section slides down to below the saw wheel driven by the push plate and the clamping plate, the hydraulic cylinder and motor one are started. The motor one drives the saw wheel to rotate, and the hydraulic cylinder drives the rotating saw wheel to move downward to cut the log section. The cut part falls off and is discharged along the unloading rack.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The wood sawing device and method for papermaking raw material processing described in this invention, by setting a feeding plate in conjunction with a guiding mechanism, can initially limit and guide the log segments during the feeding process. By using a pushing mechanism in conjunction with a clamping mechanism, it can not only push the log segments to the saw wheel to complete the cutting operation, but also ensure that the log segments do not shift to the left or right or roll axially during the cutting process. In addition, by setting a torque sensor on the outside of the saw wheel's main shaft, the load on the saw wheel can be monitored in real time to avoid damage caused by excessive load on the saw wheel.

[0023] 2. The wood sawing device and method for papermaking raw material processing described in this invention, through the guide groove opened on the guide plate, in conjunction with the guide rod and spring two, can drive the limiting rod and the mounting frame to slide up and down, so that the claws can automatically adjust the amount of vertical extension and contraction according to the log segments of different sizes. Through the torsion spring in conjunction with the limiting plate, a pair of claws can be driven from above to clamp the two sides of the log segments of different sizes. This not only further restrains the radial rolling, swinging and movement of the log segments, but also greatly improves the adaptability of the device by adapting the elastic structure to log segments of different diameters.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] like Figures 1-13As shown in the embodiment of the present invention, a wood sawing device for papermaking raw material processing includes a base 1. A gantry frame 101 is fixedly connected to the top of the base 1. An L-shaped plate 102 is fixedly connected to the gantry frame 101. A hydraulic cylinder 103 is fixedly installed on the L-shaped plate 102. A saw frame 104 is provided below the L-shaped plate 102. The output end of the hydraulic cylinder 103 passes through the L-shaped plate 102 and is fixedly connected to the top of the saw frame 104. A housing 105 is fixedly connected to the saw frame 104. A saw wheel 108 is provided inside the housing 105. A motor 106 is fixedly installed on one outer wall of the saw frame 104. A main shaft 107 is fixedly connected to the output end of the motor 106. Shaft 107 extends into housing 105 and is fixedly connected to saw wheel 108. Torque sensor 109 is fixedly installed on the side of saw frame 104 away from motor 106. Torque sensor 109 is adapted to main shaft 107. Material feeder 110 is fixedly connected to base 1. Frame 2 is provided on one side of base 1. Feed plate 3 is fixedly connected to frame 2. Feed plate 3 is adapted to both material feeder 110 and saw wheel 108. Feed plate 3 is provided with material guiding mechanism. Conveyor belt 13 is provided below feed plate 3. Pushing mechanism is evenly provided on conveyor belt 13. Conveyor belt 21 is provided above feed plate 3. Clamping mechanism is evenly provided on conveyor belt 21.

[0041] Both sides of the conveyor belt 13 are provided with mounting plates 12, and a pair of drive shafts 14 are rotatably connected between the two mounting plates 12. The conveyor belt 13 is driven by the drive shafts 14, and both mounting plates 12 are fixedly connected to the frame 2.

[0042] Both sides of the second conveyor belt 21 are provided with mounting plates 20, and a pair of drive shafts 22 are rotatably connected between the two mounting plates 20. The second conveyor belt 21 is driven by the drive shafts 22, and both mounting plates 20 are fixed to the frame 2 by a pair of connecting brackets 19.

[0043] This application addresses the issue that existing wood cutting machines lack limiting structures, making log segments susceptible to lateral deviation and axial rollover due to the rotational force of the saw wheel 108 during feeding. This results in uneven force distribution on the saw wheel 108 during cutting, leading to wobbling or wear. Furthermore, most wood cutting machines lack real-time monitoring sensors, making it impossible to provide early warnings of problems such as excessive load when the saw wheel 108 encounters knots. Workers must rely on on-site observation based on experience, often resulting in product loss by the time the fault is detected. Therefore, this application addresses this issue by using a feeding plate 3 in conjunction with a guiding mechanism to provide initial lateral limiting and auxiliary guidance for the log segments during feeding. The pushing mechanism, combined with a clamping mechanism, not only pushes the log segments to the saw wheel 108 for cutting but also ensures that the log segments do not deviate laterally or roll axially during cutting. Additionally, a torque sensor 109 is installed on the outside of the main shaft 107 of the saw wheel 108 to monitor the load on the saw wheel 108 in real time, preventing damage caused by excessive load.

[0044] It should be noted that the torque sensor 109 in this application is used in conjunction with the torque sensing section. By setting the torque sensing section on the main shaft 107 and correspondingly setting the torque sensor 109 on the outer periphery of the torque sensing section, the torque sensor 109 does not need to rotate with the main shaft 107. The torque sensing section rotates with the saw wheel 108, and the torque signal of the main shaft 107 can be collected in real time by electromagnetic induction. When the cutting load is detected to exceed the preset threshold, the hydraulic cylinder 103 slows down the descent of the drive saw frame 104, and the motor 106 synchronously reduces the speed. After the load is restored, the speed is automatically increased, realizing overload protection and stable cutting.

[0045] The material guiding mechanism includes a horizontal plate 4 and a guide roller 6. Horizontal plates 4 are provided on both sides of the feed plate 3. A bracket 5 is uniformly fixed on the horizontal plate 4. A guide roller 6 is rotatably connected to the bracket 5. Both horizontal plates 4 are fixed to the frame 2. The feed plate 3 is V-shaped. A through groove 7 is uniformly opened on both sides of the feed plate 3. The guide roller 6 is set in the through groove 7. A through groove 8 is opened at the center of the bottom of the feed plate 3.

[0046] The pushing mechanism includes a fixed sleeve 15 and a baffle. The fixed sleeve 15 is uniformly fixed on the conveyor belt 13. A push plate 17 is slidably connected inside the fixed sleeve 15. A spring 16 is fixed between the push plate 17 and the inner wall of the fixed sleeve 15. The end of the push plate 17 away from the spring 16 extends to the outside of the fixed sleeve 15. The width of the push plate 17 is smaller than the width of the through groove 7. Rubber protrusions are uniformly fixed on the side of the push plate 17 near the saw wheel 108. A rotating roller 18 is rotatably connected to the top of the push plate 17.

[0047] During operation, the worker places the entire log segment onto the feed plate 3. The V-shaped design of the feed plate 3, combined with evenly spaced guide rollers 6, initially limits the log segment from both sides, achieving automatic axial alignment of the single log without manual intervention. This prevents axial displacement of the log segment and ensures uniform cutting force. As the log segment is placed on the feed plate 3, it presses downwards against the conveyor belt 17, causing it to slide downwards and compress spring 16. Simultaneously, the rotating roller 18 at the top of this section of the baffle contacts the bottom of the log segment. Due to the rolling friction between the rotating roller 18 and the log, this section of the push plate 17 is still driven by the conveyor belt 13 before the log segment is pushed further, until an uncompressed push plate 17 is conveyed. Driven by conveyor belt 13, the log segment comes into contact with the end of the log segment away from the saw wheel 108. Subsequently, the log segment moves towards the saw wheel 108 under the combined action of push plate 17 and conveyor belt 13. When the operator determines that the portion of the log segment exceeding the saw wheel 108 has reached the preset cutting value, conveyor belt 13 and conveyor belt 21 stop, hydraulic cylinder 103 starts, and drives saw frame 104 and saw wheel 108 to move downward. At the same time, motor 106 starts and drives saw wheel 108 to rotate. The log segment is cut by the rotating and descending saw wheel 108. The cut portion falls off and is discharged along unloading rack 110. Afterward, hydraulic cylinder 103 drives saw frame 104 to rise, and conveyor belt 13 and conveyor belt 21 start again. This process is repeated to complete the segmented cutting of the log segment.

[0048] It should be noted that the rubber protrusions on the push plate 17 can increase the friction between the push plate 17 and the log segment, making it easier for the push plate 17 to push the log segment. In addition, when the push plate 17 contacts the end of the log segment away from the saw wheel 108, the rubber protrusions on the push plate 17 always remain in contact with the log segment, while the rotating roller 18 on the top of the push plate 17 does not contact the log segment.

[0049] The clamping mechanism includes a fixed sleeve 23 and clamping claws 27. Fixed sleeves 23 are uniformly fixed on the conveyor belt 21. A limit rod 24 is slidably connected inside the fixed sleeve 23. One end of the limit rod 24 extends to the outside of the fixed sleeve 23 and is fixedly connected to a mounting bracket 26. A spring 25 is fixed between the mounting bracket 26 and the outer end of the fixed sleeve 23. The spring 25 is sleeved on the limit rod 24. A pair of clamping claws 27 are rotatably connected to the mounting bracket 26. The pair of clamping claws 27 are symmetrically arranged. A torsion spring 28 is fixed between the clamping claws 27 and the mounting bracket 26. An auxiliary guide assembly is provided above the conveyor belt 21.

[0050] The auxiliary guiding assembly includes a guide plate 31 and a limiting plate 36. A pair of guide plates 31 and a limiting plate 36 are sequentially arranged above the second conveyor belt 21. The limiting plate 36 is fixed to the outer wall of the two mounting plates through a pair of hangers 37. The pair of guide plates 31 are both fixed to the inner side wall of the hangers 37. Guide grooves are opened on opposite sides of the pair of guide plates 31. Vertical grooves 29 are opened on both sides of the second fixing sleeve 23. A guide rod 30 is slidably connected in the vertical groove 29. One end of the guide rod 30 is fixed to the limiting rod 24, and the end of the guide rod 30 away from the limiting rod 24 is slidably connected to the guide groove. The claw 27 is adapted to the limiting plate 36.

[0051] The guide groove is composed of an inlet groove 32, a horizontal groove 33, an inclined groove 34 and an arc-shaped groove 35 connected in sequence. The inlet groove 32 is located on the guide plate 31 on the side close to the saw wheel 108. The inlet groove 32 is generally in the shape of a horizontal funnel.

[0052] The limiting plate 36 is composed of a flat plate portion 38, an inclined plate portion 39 and an arc plate portion 40 in sequence. The limiting plate 36 is arranged parallel to the guide plate 31. Both sides of the arc plate portion 40 near the inclined plate portion 39 are inclined surfaces.

[0053] During operation, after the push plate 17 moves the log section towards the saw wheel 108 and slides below the second conveyor belt 21, the claw 27, which has just detached from the limit plate 36, slides downward along with the mounting frame 26 under the elastic force of the second spring 25 and continuously approaches the surface of the log section. During this process, the pair of claws 27 on the mounting frame 26 slowly retract under the tension of the torsion spring 28 until they contact the surface of the log section and complete the clamping and fixing. Afterward, the claws 27 assist the push plate 17 in moving the log section towards the saw wheel 108 until the claws 27 detach from the surface of the log section under the drive of the second conveyor belt 21 and are transmitted to the guide plate 31. During this process, after the claws 27 leave the surface of the log segment, they continue to retract under the tension of the torsion spring 28 until the pair of claws 27 return to their original positions and the torsion spring 28 is in its natural state. At the same time, the mounting bracket 26 moves away from the fixing sleeve 23 under the elastic force of the second spring 25 and completes its reset. When the guide rod 30 on the limiting rod 24 slides into the transverse groove 33 along the inlet groove 32, the pair of claws 27 then contact the limiting plate 36. At this time, both the second spring 25 and the torsion spring 28 are in their natural state. When the guide rod 30 slides into the inclined groove 34, it is squeezed by the inclined groove 34. While sliding along the inclined groove 34, it also slides downward along the vertical groove 29, causing the limit rod 24 and the mounting bracket 26 to slide downward together and compress the second spring 25. During this process, the pawl 27 slides along the inclined plate 39, and the torsion spring 28 remains in its natural state. After the guide rod 30 slides into the arc-shaped groove 35, the second spring 25 remains in a compressed state, and the pawl 27 slides along the arc-shaped groove 40. The sliding mechanism, supported by the inclined surfaces on both sides of the arc plate 40, allows the pair of claws 27 to fully open. The torsion spring 28 stores energy until the claws 27 disengage from the arc plate 40 and retract under the tension of the torsion spring 28. After the guide rod 30 disengages from the arc groove 35, the mounting bracket 26 slides downward again under the elastic force of the second spring 25, completing the clamping action with the next log segment. This application, through the guide groove on the guide plate 31, in conjunction with the guide rod 30 and the second spring 25, can drive the limiting rod 24 and the mounting bracket 26 to slide up and down, allowing the claws 27 to automatically adjust the amount of vertical extension and contraction according to different sizes of log segments. Through the torsion spring 28 in conjunction with the limiting plate 36, the pair of claws 27 can clamp the sides of different sizes of log segments from above, which not only further constrains the radial rolling, swinging and swaying of the log segments, but also greatly improves the adaptability of the device by adapting to log segments of different diameters through the elastic structure.

[0054] A fixed frame 9 is fixedly connected to the outer wall of the frame 2 near the saw wheel 108. A second motor 10 is fixedly mounted on the fixed frame 9. A rotating shaft 11 is fixedly connected to the output end of the second motor 10. The rotating shaft 11 is fixedly connected to one of the drive shafts 14. A synchronous pulley 41 is fixedly connected to the rotating shaft 11. A second bracket 42 and a third bracket 46 are arranged sequentially above the fixed frame 9. Both the second bracket 42 and the third bracket 46 are fixedly connected to one of the connecting frames 19. A second rotating shaft 43 is rotatably connected to the second bracket 42. Two synchronous pulleys 44 are fixedly connected to shaft 2 43. A rotating shaft 47 is rotatably connected to bracket 3 46. Two synchronous pulleys 48 are fixedly connected to rotating shaft 3 47. A rotating shaft 50 is fixedly connected to one of the drive shafts 2 22. Synchronous pulley 41 is driven by one of the synchronous pulleys 44 through synchronous belt 45. The other synchronous pulley 44 is driven by one of the synchronous pulleys 48 through synchronous belt 49. The other synchronous pulley 48 is driven by one of the synchronous pulleys 51 through synchronous belt 52.

[0055] During operation, motor 10 drives shaft 11 to rotate, which in turn drives drive shaft 14 to drive conveyor belt 13. Simultaneously, synchronous pulley 41 on shaft 11, in conjunction with synchronous belt 45, drives one synchronous pulley 44 to rotate, causing shaft 13 to drive the other synchronous pulley 44 to rotate. This, in turn, causes shaft 17 to rotate under the influence of synchronous belt 49 and one synchronous pulley 48. The other synchronous pulley 48, via synchronous belt 52, drives synchronous pulley 51 to rotate, causing shaft 17 to drive drive shaft 22 to rotate, thus... The second conveyor belt 21 is driven accordingly. When the hydraulic cylinder 103 and the first motor 106 are started, the second motor 10 stops driving the first conveyor belt 13 and the second conveyor belt 21. After the cutting is completed, when the hydraulic cylinder 103 and the first motor 106 stop, the second motor 10 drives the first conveyor belt 13 and the second conveyor belt 21 again. Through this transmission structure, the transmission speed of the second conveyor belt 21 is the same as the transmission speed of the first conveyor belt 13, which in turn makes the transmission speed of the claw 27 and the push plate 17 the same, so that the log segment is clamped and moves towards the saw wheel 108.

[0056] A pair of arc-shaped damping sleeves 53 are fixedly connected to both sides of the outer wall of the mounting bracket 26. An arc-shaped piston rod 54 is slidably connected in the inner cavity of the arc-shaped damping sleeve 53. One end of the arc-shaped piston rod 54 extends to the outside of the arc-shaped damping sleeve 53 and is fixedly connected to a connecting rod 55. The end of the connecting rod 55 away from the arc-shaped piston rod 54 is fixedly connected to the claw 27. A pair of arc-shaped through grooves 56 are opened on the inner end of the arc-shaped piston rod 54.

[0057] During operation, after the pawl 27 is fully opened by the support of the arc plate 40, the connecting rod 55 connected to the pawl 27 drives the arc piston rod 54 to slide into the damping sleeve. The damping oil in the damping sleeve flows through the arc groove 56. When the pawl 27 disengages from the arc plate 40 and retracts under the action of the torsion spring 28, the resistance of the damping oil causes the pawl 27 to slowly drive the arc piston rod 54 out of the damping sleeve. This application fills the damping sleeve with damping oil so that the pawl 27 will not quickly retract and reset due to the force of the torsion spring 28 after disengaging from the arc plate 40, thus preventing the pawl 27 from completing the retraction and reset action before contacting the log segment, and facilitating the pawl 27 to achieve the clamping function.

[0058] A method for sawing wood for papermaking raw material processing, applicable to the aforementioned wood sawing apparatus for papermaking raw material processing, includes the following steps:

[0059] S1: The worker places the whole log section on the guide roller 6 of the feed plate 3, starts the motor 10, and the conveyor belt 13 and the conveyor belt 21 start to drive. The log section is moved towards the saw wheel 108 by the clamp on the conveyor belt 13.

[0060] S2: After the log section slides to below the second conveyor belt 21, the claw 27 that disengages from the arc plate 40 slowly begins to retract. At the same time, after the guide rod 30 disengages from the arc groove 35, the limiting rod 24, under the elastic force of the second spring 25, drives the mounting frame 26 and the claw 27 to slide towards the log section until the claw 27 is in contact with the surface of the log section, thus completing the clamping action.

[0061] S3: After the log segment slides down to below the saw wheel 108 driven by the push plate 17 and the clamping plate, the hydraulic cylinder 103 and the motor 106 are started. The motor 106 drives the saw wheel 108 to rotate, and the hydraulic cylinder 103 drives the rotating saw wheel 108 to move downward to cut the log segment. The cut part falls off and is discharged along the unloading rack 110.
