Description

Technical Field

[0001] This invention belongs to the field of industrial material sawing and processing, and particularly relates to a push-type sawing device and sawing method. Background Technology

[0002] Bamboo and wood sawing equipment typically consists of several components, including a frame, saw blade, drive system, feeding system, positioning device, safety device, control panel, chip removal device, and cooling system. These components provide stable support and power, enabling the saw blade to efficiently cut materials such as wood, metal, or plastic.

[0003] During operation, the feeding system delivers the material to be cut to the sawing area, and the positioning device ensures that the material is held in the correct position and angle, thereby improving cutting accuracy. The control panel allows the operator to preset parameters such as cutting speed, depth, and angle. In addition, safety devices such as protective covers and emergency stop buttons effectively ensure the safety of operators.

[0004] To improve production efficiency, the equipment is also equipped with a chip removal device to collect and discharge chips generated during the cutting process. In some high-load applications, a cooling system is configured to help prevent the saw blade from overheating and the material from deforming.

[0005] In existing technologies, for example, for chopsticks, sawing equipment uses a single-groove sawing mode. A single sawing groove is set in a single machine, and the saw blade moves into the groove to saw the material. Since sawing can only be carried out in one groove, the production efficiency of the equipment is limited. After each sawing is completed, the machine needs to be stopped and refilled with material. At the same time, the single-groove design is not suitable for handling materials of various specifications and shapes, which leads to complex adjustments or machine shutdowns when the sawing length needs to be changed. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems by providing a push-type sawing device and sawing method that can solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A push-type sawing device includes a frame, on which are provided an alternating feeding component having a loading slot and a feeding setting slot, a pushing component for intermittently pushing strip material in the feeding setting slot according to a set length and causing at least a portion of the strip material to extend beyond the feeding setting slot, a fixing component for fixing the strip material relative to the feeding setting slot, a clamping component for partially clamping a portion of the strip material extending beyond the feeding setting slot, and a sawing component for sawing the portion of the strip material extending beyond the feeding setting slot.

[0009] Furthermore, the alternating feeding assembly includes a first rotating shaft connected to a rotating shaft drive device. The alternating feeding assembly also includes at least two feeding slots that rotate around the first rotating shaft. The two feeding slots are interconnected by a linkage mechanism, and the linkage mechanism is at least partially fixedly connected to the first rotating shaft.

[0010] Furthermore, the linkage mechanism includes a first link fixedly connected to the first rotating shaft in a circumferential direction, and transmission rods respectively hinged to both ends of the first link. One end of the transmission rod of each first link is fixedly connected to the end of one of the feeding troughs, and the other end of the transmission rod of each first link is fixedly connected to the end of the other feeding trough. The linkage mechanism also includes a second link hinged to the first link. The middle part of the second link is hinged to the middle part of the first link. One end of the second link is hinged to the end of one of the feeding troughs, and the other end of the second link is hinged to the end of the other feeding trough.

[0011] Furthermore, the feeding assembly includes a feeding plate that moves axially along the feeding groove, and the feeding plate is driven by a feeding drive device.

[0012] Furthermore, the fixing component includes a movable clamping member and at least one fixed clamping member. The movable clamping member is provided on the pushing component. The movable clamping member has space for the cutting tool to enter and exit. At least one of the fixed clamping members has space for the cutting tool to enter and exit.

[0013] Furthermore, the clamping assembly includes a multi-axis moving mechanism, on which a partially encircling manipulator is provided that contacts the bottom side of the material, and a lifting clamping component that contacts at least the top of the material. The partially encircling manipulator and the lifting clamping component form a three-way contact with the material and clamp the material.

[0014] Furthermore, the partial encircling manipulator includes two partial encircling claws hinged to the multi-axis moving mechanism, the partial encircling claws being connected to a driving force, and the lifting clamping component including a lifting and moving clamping block, the clamping block being connected to a clamping driver that drives the clamping block to move.

[0015] Furthermore, the multi-axis moving mechanism includes an X-axis moving frame that moves along the axial direction of the feeding trough, and a Y-axis moving frame that is slidably connected to the X-axis moving frame. A Z-axis lifting frame is provided on the Y-axis moving frame, and each frame is driven by a linear drive power.

[0016] Furthermore, the Z-axis lifting frame includes several vertically arranged and parallel optical rods, which are fixed together by several connecting brackets; the clamping block is slidably connected to at least two optical rods, and the clamping driver is fixed to the connecting brackets; the partial encircling manipulator includes two partial encircling claws hinged to the lower end of the Z-axis lifting frame, and a claw linkage frame hinged to each partial encircling claw is mounted on the Z-axis lifting frame; a Z-axis lifting driver connected to the Z-axis lifting frame is mounted on the Y-axis moving frame. The Z-axis lifting driver is the aforementioned driving force.

[0017] Furthermore, the sawing assembly includes a swing saw blade frame hinged to the frame, a saw blade mounted on the swing saw blade frame, and a saw blade drive device for driving the saw blade to rotate. The swing saw blade frame and the frame are connected by a swing drive mechanism.

[0018] This application also provides a sawing method for the aforementioned pusher-type sawing equipment, comprising the following steps:

[0019] S1. Adjust the position of one of the feeding troughs of the alternating feeding component, which carries the strip material, to the feeding setting trough, and simultaneously adjust the position of the other feeding trough to the feeding trough. Place the strip material to be sawed into the other feeding trough of the feeding trough.

[0020] S2, the pushing component pushes the strip material in the feeding setting slot in S1 to move, forcing at least a portion of the strip material to extend out of the feeding setting slot;

[0021] S3. A fixing component is used to press the strip material placed in the feeding trough in S2, and a clamping component is used to clamp a section extending out of the feeding setting trough.

[0022] S4. The sawing assembly saws the section of the strip material that extends outside the feeding slot to obtain sawn material.

[0023] Repeat steps S2-S4 above to cut the strip material multiple times;

[0024] S5. When the last strip of material is sawn, the clamping assembly and the movable pressing member provided on the pushing assembly fix the last strip of material at both ends, and then repeat S4.

[0025] S6. After passing through S5, the last tail material is restricted by one end of the pushing component and the tail material unloading mechanism unloads the tail material, causing the tail material to leave the feeding trough.

[0026] S7. Repeat S1-S6 above to perform non-stop sawing of strip materials.

[0027] Compared with existing technologies, the advantages of this application are as follows: by using an alternating feeding trough, continuous cutting of materials can be achieved. When one feeding trough is cutting, another feeding trough can prepare the next material. The material can be cyclically sawed without stopping the machine, which greatly improves production efficiency. At the same time, the push-out sawing method allows the equipment to quickly adjust the sawing length without stopping the machine or changing parts. Attached Figure Description

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0046] Example 1

[0047] like Figures 1-5 As shown, the push-type sawing equipment is used to cut long strips of material into equal lengths. Specifically, the push-type sawing equipment includes a frame 1, with a feed window on the side of the frame closest to the operator and a discharge window located next to the feed window. The operator puts the strip of material to be sawed or a bundle of strips of material into the feed window. The strip of material is, for example, strips of bamboo after splitting raw bamboo or strips of wood after splitting raw logs. The sawn material can be processed and used for tableware, such as chopsticks, etc. The sawing equipment cuts the strip of material into several segments, and several segments flow out from the discharge window, while the waste is recycled through a waste recycling system.

[0048] Specifically, the push-type sawing equipment includes an alternating feeding assembly 2 having a waiting feeding slot and a feeding setting slot; a pushing assembly 3 for intermittently pushing the strip material in the feeding setting slot according to a set length and causing at least a portion of the strip material to extend beyond the feeding setting slot; a fixing assembly 4 for fixing the strip material relative to the feeding setting slot; a clamping assembly 5 for partially clamping a portion of the strip material extending beyond the feeding setting slot; a sawing assembly 6 for sawing the portion of the strip material extending beyond the feeding setting slot; and a waste recycling system for collecting waste.

[0049] The feeding setting slot of the alternating feeding component 2 is directly used as the material load during sawing. At this time, the waiting feeding slot can be replenished. The waiting feeding slot and the feeding setting slot are independent of each other and do not affect each other, which can realize non-stop operation and improve production efficiency.

[0050] The feeding component 3 pushes strip materials intermittently at a set distance, which can meet the sawing requirements of various lengths and lengths of sawn materials, thereby improving the versatility of the equipment.

[0051] The combination of fixing component 4 and clamping component 5 can fix and clamp the strip material, which can prevent the material from shifting during the sawing process, thereby improving the flatness of the sawing surface and eliminating rework. At the same time, it can also prevent the material from disturbing the sawing component during the sawing process, thereby extending the service life of the sawing component.

[0052] Waste recycling systems can recycle final waste materials to improve the cleanliness of the working environment.

[0053] like Figures 8-9 As shown, the alternating feeding assembly 2 includes a first rotating shaft 2X and two feeding troughs 20 for carrying materials. The two feeding troughs 20 are connected by two sets of linkage mechanisms 21, at least a portion of which is fixedly connected to the first rotating shaft 2X. The two feeding troughs 20 can operate alternately, such that one feeding trough 20 reaches the material to be fed trough while the other reaches the feeding set trough.

[0054] The first rotating shaft 2X is connected to the rotating shaft drive device 22. The rotating shaft drive device 22 drives the first rotating shaft 2X to rotate, and the rotation of the first rotating shaft 2X will drive the linkage mechanism 21 to move, so that the two feeding troughs 20 can move alternately.

[0055] The first rotating shaft 2X is rotatably connected to the frame 1. The first rotating shaft 2X can be a single shaft or two short shafts spaced apart and coaxial.

[0056] like Figure 9 As shown, the linkage mechanism 21 includes a first link 210 that is circumferentially fixedly connected to the first rotating shaft 2X. For example, the middle part of the first link 210 is circumferentially fixedly connected to the first rotating shaft 2X. Transmission rods 211 are respectively hinged to both ends of the first link 210. One end of the transmission rod 211 of each first link 210 is fixedly connected to the end of one of the feeding troughs 20, and the other end of the transmission rod 211 of each first link 210 is fixedly connected to the end of another feeding trough 20.

[0057] The linkage mechanism 21 also includes a second link 212 hinged to the first link 210. The middle part of the second link 212 is hinged to the middle part of the first link 210. Of course, a protrusion can be added to the middle part of the first link 210, and the middle part of the first link 210 is hinged to the protrusion. One end of the second link 212 is hinged to the end of one of the feeding troughs 20, and the other end of the second link 212 is hinged to the end of the other feeding trough 20.

[0058] The first link 210, the second link 212 and the transmission rod 211 form a link motion mechanism similar to the figure "8", which can ensure that the opening of the feeding trough 20 always faces upwards when the feeding trough 20 moves to any position.

[0059] In this embodiment, the shaft drive device 22 is a chain drive device, but it can also be designed as a pneumatic drive device or a motor drive device according to the actual working conditions.

[0060] In this embodiment, the number of feeding troughs 20 can be redesigned according to actual working needs. The material is placed along the length of the feeding trough 20, and the two feeding troughs 20 can rotate around the first rotating shaft 2X in an alternating manner.

[0061] Specifically, since a set of linkage mechanisms 21 are respectively set at both ends of the feeding trough 20, in order to ensure the horizontal and stable operation of the feeding trough 20, the transmission chains 220 on both sides are connected to each other through a synchronous rod 223, so that the movement of the transmission chains 220 on both sides remains the same, ensuring the smooth movement of the feeding trough 20.

[0062] Meanwhile, in order to ensure the stability and stillness of the feeding trough 20 during processing (e.g., at the feeding setting position), a trough locking rod 23 for locking the linkage mechanism 21 is also provided in the frame 1, so that the feeding trough 20 at the feeding setting position can remain stable during processing, and to prevent the stability of the feeding trough 20 at the feeding setting position from being affected when the operator feeds the feeding trough 20 in the feeding area.

[0063] Among them, such as Figures 6-8 As shown, the material trough locking rod 23 can extend and retract to lock the linkage mechanism 21. At the end of the material trough locking rod 23 away from the linkage mechanism 21, there is a locking rod driving device 24 that drives the material trough locking rod 23 to reciprocate along the first rotating shaft 2X axis. In this embodiment, the locking rod driving device 24 is a hydraulic driving device, but it can also be designed as a pneumatic driving device or a linear motor driving device according to the actual working conditions.

[0064] The material trough locking hole 25 includes a first locking hole 250 on the first connecting rod 210 through which the material trough locking rod 23 passes, and a second locking hole 251 on the second connecting rod 212 through which the material trough locking rod 23 passes. The first locking hole 250 and the second locking hole 251 can be simultaneously passed through by the material trough locking rod 23, and the material trough locking rod 23 is clearance-fitted with the first locking hole 250 and the second locking hole 251, so that the material trough 20 is offset when fixed.

[0065] To ensure that the trough locking rod 23 can stably pass through the first locking hole 250 and the second locking hole 251 simultaneously, the rod end of the trough locking rod 23 near the linkage mechanism 21 gradually increases in diameter towards the rod body in a tapered shape. The advantage of this is that if the linkage mechanism 21 deviates slightly after reaching the designated position, the tapered structure with a transition function can correct the linkage mechanism 21, so that the trough locking rod 23 passes through the first locking hole 250 and the second locking hole 251 as expected.

[0066] In addition to the above structure, misalignment of materials in the feeding trough 20 of the feeding area during loading will increase the processing scrap rate. Manual alignment is inefficient and dangerous. Therefore, a support plate 26 for aligning materials is provided at one end of the feeding trough 20 in the feeding area. Figure 10 As shown, when the feeding trough 20 moves to the loading area, the support plate 26 can automatically flip to one end of the feeding trough 20. When the operator puts in the material, the material is pressed against the support plate 26, so that the material can remain neat before processing. The support plate 26 is connected to the tilting mechanism. The tilting mechanism is used to drive the movement and opening and closing of the support plate 26 relative to the feeding trough 20, so that the support plate 26 plays an alignment role during the loading process and avoids the action of the feeding trough 20 during the movement of the feeding trough 20.

[0067] like Figure 10 As shown, the two feeding troughs 20 are defined as the first feeding trough and the second feeding trough. When either the first feeding trough or the second feeding trough is in the feeding setting position, the other one is in the waiting feeding position.

[0068] Specifically, when the processing operation begins, the operator places the material in any one of the feeding troughs 20. Assuming that the first feeding trough is currently in the waiting-to-load position and the second feeding trough is in the feeding setting position, after the material is filled, the two feeding troughs 20 are switched by the alternating feeding component 2. This causes the first feeding trough, which is filled with material, to rotate and move to the feeding setting position, while the second feeding trough, which is empty or has been processed, rotates and moves to the waiting-to-load position. When the operator processes the material in the first feeding trough using the push-type sawing equipment, the material is simultaneously placed into the second feeding trough, realizing a streamlined operation. After the material in the first feeding trough is processed, the first feeding trough returns to the waiting-to-load position, while the second feeding trough, after being filled, moves to the feeding setting position for processing.

[0069] In this embodiment, the two feeding troughs 20 do not rotate cyclically in one direction, but rather move back and forth in a clockwise and counterclockwise cycle. Specifically, when the first feeding trough needs to be transferred from the waiting-to-feed trough to the feeding setting trough, as shown in the figure, it rotates clockwise around the first rotating shaft 2X to the feeding setting trough. At this time, the second feeding trough simultaneously rotates clockwise to the waiting-to-feed trough. After processing is completed, the first feeding trough rotates counterclockwise from the processing area around the first rotating shaft 2X to the waiting-to-feed trough, and similarly, the second feeding trough simultaneously rotates counterclockwise to the feeding setting trough.

[0070] like Figure 9 As shown, in this embodiment, the aforementioned rotating shaft drive device 22 includes a transmission chain 220 and a transmission sprocket assembly 221. The transmission sprocket assembly 221 is fixedly connected to the first rotating shaft 2X. At the same time, the transmission chain 220 and the transmission sprocket assembly 221 mesh with each other. The transmission chain 220 is also connected to a power source A222. The transmission steps are as follows: the power source A222 drives the transmission chain 220 to move, which in turn drives the transmission sprocket assembly 221 to rotate, which in turn drives the first rotating shaft 2X to rotate. Then, through the movement of the first connecting rod 210 and the second connecting rod 212, the feeding trough 20 is finally driven to perform alternating movement around the first rotating shaft 2X.

[0071] like Figure 10 As shown, the push-type sawing equipment also includes a push mechanism with a pressing function. The push mechanism with the pressing function includes a push component 3 set at one end of the feeding trough 20 located in the feeding setting slot. The push component 3 includes a push plate 30 that moves along the axial direction of the feeding trough 20. The push plate 30 is driven by a push drive device 31, which is a screw motor drive device. It can also be designed as a pneumatic drive device or a hydraulic drive device according to the actual working conditions. When the material needs to be processed, the push drive device 31 drives the push plate 30 to abut against one end of the material, pushing the material towards the sawing component 6, and then the sawing component 6 cuts it. The push plate 30 can adjust the distance it travels each time according to the length of the material to be processed, which greatly improves the practicality of the device.

[0072] like Figure 11 As shown, the pusher drive device 31 includes a sliding frame 310 slidably connected to the frame 1, a pusher plate 30 fixed to the sliding frame 310, the sliding frame 310 and the frame 1 connected by a lead screw pair 311, and a pusher motor 312 connected to the lead screw pair 311. Meanwhile, in order to ensure the stability of the movement of the pusher plate 30, the sliding frame 310 and the frame 1 are connected by a guide rod pair 313.

[0073] The lead screw assembly 311 and the guide rod assembly 313 are parallel to each other, and the guide stroke of the guide rod assembly 313 is greater than the axial length of the feeding groove 20. Driven by the pusher motor 312, the lead screw assembly 311 can move the pusher plate 30 from one axial end of the feeding groove 20 to the other axial end of the feeding groove 20.

[0074] like Figure 10 As shown, to prevent displacement and deformation of materials during cutting and processing, the fixing component 4 includes a movable clamping member 40 and at least one fixed clamping member 41. Specifically, the movable clamping member 40 is located on the side of the pusher plate 30 near the material via a lifting driver 42. The movable clamping member 40 moves with the pusher plate 30. During processing, the movable clamping member 40 clamps the material through lifting control, thereby stabilizing the material. It works together with the fixed clamping member 41 to fix the processed material.

[0075] The fixed clamping member 41 and the movable clamping member 40 have contoured contact surfaces that conform to the material, and the fixed clamping member 41 and the movable clamping member 40 are respectively connected to the lifting drive 42. The lifting drive 42 is, for example, a cylinder or a hydraulic cylinder.

[0076] Furthermore, the movable clamping member 40 in this embodiment specifically includes two spaced-apart clamping uprights 400. The tops of the two clamping uprights 400 are fixed to each other and to the lifting drive 42 provided on the sliding frame 310 via a bending portion. A reinforcing block 401 is provided between the tops of the two clamping uprights 400 to ensure the mechanical strength of the clamping uprights 400. A space is reserved between the two clamping uprights 400 for the sawing assembly 6 to enter. Specifically, as shown... Figure 10 As shown, there are several fixed clamping parts 41, and these fixed clamping parts 41 are evenly spaced and distributed above the feeding trough 20 in the feeding setting slot. Since the materials processed by this equipment are mostly long strips, when sawing, the middle part of the material will jump due to the material, which is very easy to cause accidents. Therefore, the above-mentioned fixed clamping parts 41 are designed to fix the middle part of the material, improve safety and processing accuracy.

[0077] There are four sets of fixing clamping components 41, three of which have the same structure, each including a clamping claw 412 that moves vertically, and each clamping claw 412 is independently connected to a lifting drive air / hydraulic cylinder 411. The purpose is to allow each fixing clamping component 41 to be independently controlled. The clamping claw 412, for example... Figure 10 As shown, the device consists of two parallel, spaced components with contoured structures. This design allows the clamping claw 412 to better contact the material being processed, ensuring material stability during the cutting process. The structure of the fixed clamping member 41 closest to the clamping assembly 5 differs from the structures of the three sets of fixed clamping members 41 mentioned above. The structure of the fixed clamping member 41 closest to the clamping assembly 5 is the same as that of the movable clamping member 40, for example... Figure 16 As shown, the fixed clamping member 41 closest to the clamping assembly 5 includes two spaced clamping plates 410 and a lifting drive air / oil cylinder 411 that drives the two clamping plates 410 to move up and down. The space between the lower ends of the two clamping plates 410 is formed for the sawing assembly 6 to enter, which can also be understood as having a space for the cutting tool to enter and exit.

[0078] like Figures 12-13 As shown, the clamping assembly 5 is located at the discharge window and includes at least one clamping mechanical claw. Preferably, in this embodiment, the clamping assembly 5 has two clamping mechanical claws. When the pushing assembly 3 pushes at least partially of the material out of the feeding trough 20, the two clamping mechanical claws simultaneously clamp the suspended end of the material. The sawing assembly 6 then performs sawing. The sawn material is carried out of the pushing-type sawing device by the clamping mechanical claws. These clamping mechanical claws can move in three axes and can achieve high-precision positioning and clamping force adjustment through a drive device, thus adapting to materials of different shapes and sizes. During the clamping process, the clamping mechanical claws can accurately apply uniform pressure to the material, ensuring that the material remains stable and does not shake during sawing, thereby improving the accuracy and efficiency of sawing.

[0079] Once a processing step is completed, the clamping mechanical claws will release, and the remaining material after sawing will be pushed out by the pusher assembly 3 to enter the subsequent processing steps.

[0080] like Figure 10 As shown, the clamping assembly 5 is a multi-axis moving clamping assembly. Its specific structure includes a multi-axis moving mechanism 50, on which a partially encircling manipulator 51 contacts the bottom side of the material, and a clamping block 52 contacts at least the top of the material. The partially encircling manipulator 51 and the clamping block 52 form a three-way contact with the material and clamp it. The clamping block 52 is a lifting clamping block, and it is connected to a clamping actuator 53, such as a cylinder or hydraulic cylinder.

[0081] like Figure 10 As shown, the multi-axis moving mechanism 50 includes an X-axis moving frame 50X that moves axially along the feeding trough 20, and a Y-axis moving frame 50Y that is slidably connected to the X-axis moving frame 50X. A Z-axis lifting frame 50Z is provided on the Y-axis moving frame 50Y. Each frame is driven by a linear drive power, such as a linear motor, a cylinder, or a hydraulic cylinder. The X-axis moving frame 50X is connected to the aforementioned guide rod pair 313.

[0082] Of course, to ensure the smooth movement of each frame, each frame is also equipped with a guide assembly, such as guide rods. The Z-axis lifting frame 50Z includes several vertically arranged and parallel guide rods 54, for example, four rods, which are fixed together by several connecting brackets 55. These rods can guide their own movement or guide the movement of other mechanisms. For example, the clamping block 52 is slidably engaged with at least two guide rods 54, which ensures the stable lifting of the clamping block 52. The clamping block 52 is connected to the clamping lifting frame 56, which is slidably engaged with two of the guide rods 54. The clamping drive 53 is fixed to the connecting brackets 55.

[0083] The partial gripping manipulator 51 includes two partial gripping claws 510 hinged to the lower end of the Z-axis lifting frame 50Z. A claw linkage frame 57, hinged to each partial gripping claw 510, is mounted on the Z-axis lifting frame 50Z. A Z-axis lifting driver 42, connected to the Z-axis lifting frame 50Z, is mounted on the Y-axis moving frame 50Y. The Z-axis lifting driver 42 can be a cylinder, hydraulic cylinder, or linear motor, etc. When the Z-axis lifting driver 42 drives the Z-axis lifting frame 50Z upward, the two partial gripping claws 510 are in an open state. Conversely, when they are lowered, they are in a gripping state.

[0084] In a preferred embodiment, a tail material unloading mechanism 7 is provided on the frame 1 at one end of the feeding trough 20 (at the feeding setting slot) near the clamping assembly 5. The tail material unloading mechanism 7 includes a U-shaped material carrier 70 that conforms to the feeding trough 20 and is hinged to the frame 1 at its bottom. The inner wall of the U-shaped material carrier 70 is flush with the inner wall of the feeding trough 20. A linkage-type drive assembly 71 is provided on the frame 1 to drive the U-shaped material carrier 70 to tilt away from the feeding trough 20. The linkage-type drive assembly 71 includes two linkage rods that are hinged to each other. One linkage rod is hinged to the bottom side of the U-shaped material carrier 70, and the other linkage rod is hinged to the frame 1. An unloading driver 72 is hinged to the frame 1. The unloading driver 72 is, for example, a cylinder or hydraulic cylinder. The power end 72 is hinged to the hinge of the two linkage rods. When the unloading drive 72 is, for example, a cylinder, the retraction of the cylinder's telescopic rod causes the two linkage rods to form a V-shape. At this time, the U-shaped loading component 70 is in an inclined state; conversely, it is in an upright state. After the last section of material is sawn, the tail material unloading mechanism 7 tilts outward, causing the tail material to detach from the feeding trough 20. The tail material then enters the waste recycling system. The waste recycling system includes an inclined guide trough 73 connected to the lower side of the U-shaped loading component 70. An inclined waste conveying device 74, whose lower end extends beyond the lower end of the inclined guide trough 73, is provided on the frame 1. The tail material conveyed by the inclined waste conveying device 74 enters the ton bag. The inclined waste conveying device 74 is, for example, a crawler-type conveyor. The crawler has evenly spaced notches to prevent tail material from detaching during conveying. When sawing the last section of material, all fixing components 4 are inactive. The last section is then secured at both ends by clamping components 5 and movable clamping components 40. The saw blade of the sawing assembly 6 cuts the last section through the space reserved by the movable clamping components 40. This method solves the problem of securing and processing the last section of material. Simultaneously, since the movable clamping components 40 are mounted on the pusher plate 30, after sawing, the movable clamping components 40 return to their original position, while the pusher plate blocks the waste material, and the U-shaped loading component 70 tilts synchronously to collect the waste.

[0085] Specifically, during processing, it is unavoidable that residual material will be produced to meet cutting requirements, as well as debris and waste generated during cutting. This debris and short pieces of waste generated during processing will fall onto the drive track 75 of the waste recycling system. The drive track 75 then transports the debris and waste to the collection box. During processing, after sawing, the debris and short pieces of waste fall onto the drive track 75. This system is motor-driven, allowing the drive track to operate at a stable speed. The surface of the drive track 75 has a special anti-slip design to ensure that the debris and waste move forward steadily, preventing blockages and accumulation. The collection box is located at the end of the drive track 75, facilitating easy collection and disposal of waste by operators, reducing site pollution.

[0086] like Figure 10 As shown, the sawing assembly 6 is located at one end of the feeding trough 20 away from the pushing assembly 3. Specifically, when the pushing assembly 3 pushes the material toward the sawing assembly 6, part of the material will be suspended outside one end of the feeding trough 20. After the set stroke is pushed, the sawing assembly 6 is driven to cut off the suspended part of the material with the saw blade, thereby obtaining the cut material and completing the cutting process.

[0087] The sawing assembly 6 includes a swing saw blade holder 60 hinged to the frame 1, a saw blade 61 mounted on the swing saw blade holder 60, and a saw blade drive device 62 for driving the rotation of the saw blade 61. The rotation of the saw blade 61 can be driven by a belt drive / chain drive structure, etc. The power is provided by a servo motor.

[0088] The oscillating saw blade holder 60 and the frame 1 are connected by an oscillating drive mechanism. Specifically, the oscillating drive mechanism includes an inclined rack 63 hinged to the suspended side of the oscillating saw blade holder 60, and a gear 64 meshing with the inclined rack 63 on the frame 1. The gear 64 is connected to the drive motor 66 via a reducer 65. When the drive motor 66 is working, the gear 64 rotates, and the inclined rack 63 drives the oscillating saw blade holder 60 to oscillate clockwise and counterclockwise. During this process, for example, clockwise upward oscillation causes the saw blade 61 to contact the material and cut it; conversely, clockwise upward oscillation causes the saw blade 61 to return to its original position. To ensure stable meshing between the inclined rack 63 and the gear 64, a roller 650 is provided on the reducer 65 or the frame 1 to movably contact the inclined rack 63. The roller 650 contacts the surface of the inclined rack 63 away from the teeth.

[0089] Meanwhile, a large amount of dust is generated during the sawing process. In order to reduce pollution to the external environment, the waste recycling system also includes a dust collection device 76 installed near the saw blade 61 in the saw assembly 6. The dust collection device 76 can suck the suspended dust generated during the processing into the collection device in a timely manner to ensure the cleanliness and safety of the working environment.

[0090] Example 2

[0091] Based on Embodiment 1, this embodiment describes a sawing method for a push-type sawing device, including the following steps:

[0092] S1. Adjust the position of one of the feeding troughs 20 carrying strip material in the alternating feeding component 2 to the feeding setting position, and simultaneously adjust the position of the other feeding trough 20 to the waiting feeding position, and put the strip material to be sawed into the other feeding trough 20 of the waiting feeding position.

[0093] S2, the pushing component 3 pushes the strip material in the feeding setting slot in S1 to move, forcing at least a portion of the strip material to extend out of the feeding setting slot;

[0094] S3. The fixing component 4 is used to press the strip material placed in the feeding trough 20 in S2, and the clamping component 5 is used to clamp a section of material extending out of the feeding setting trough.

[0095] S4, the sawing assembly 6 saws the section of the strip material that extends outside the feeding trough to obtain sawn material;

[0096] Repeat steps S2-S4 above to cut the strip material multiple times;

[0097] S5. When the last strip of material is sawn, the movable clamping part 40 and the clamping part 5 on the pushing assembly 3 fix the last strip of material at both ends, and then repeat S4.

[0098] S6. After passing through S5, the last tail material is restricted by one end of the pushing component 3 and the tail material unloading mechanism 7 unloads the tail material, causing the tail material to leave the feeding trough 20.

[0099] S7. Repeat S1-S6 above to perform non-stop sawing of strip materials.
