Description

Technical Field

[0001] This utility model relates to the field of saw blade processing technology, and in particular to a saw blade disassembly and assembly device. Background Technology

[0002] In the mass production of saw blades, the saw blades need to be installed on the saw barrel first. After inspection or processing is completed, the saw blades are then disassembled. These are the key processes in the finished product stage. Specifically, after the saw blades have completed basic processing such as the base body and the cutting head, they need to be uniformly installed on the saw barrel to form an assembly before dynamic balancing testing, cutting edge fine grinding, and appearance inspection can be carried out. After all inspections and processing meet the standards, the saw blades are removed from the saw barrel, classified, and stored. The efficiency of this process directly determines the saw blade production cycle, finished product qualification rate, and capacity utilization rate.

[0003] Currently, the existing saw blade assembly and disassembly mainly involves operators first using an overhead crane to hoist the saw blades to the saw cylinder station in batches. Two to three people then manually straighten the saw blades to align the inner hole with the saw cylinder shaft diameter, pushing each blade to a preset position and separating them with spacers. After all blades are assembled, a torque wrench is used to tighten the shaft end locking nuts or circumferential bolts one by one. Anti-loosening washers are then added and the blades are manually tapped to compact them. The assembly of a single saw cylinder takes about 2-3 hours. If dynamic balance deviations or re-inspections are found in subsequent inspection / processing stages, the bolt loosening, saw blade disassembly, reassembly, and tightening process must be repeated. The additional disassembly and assembly time for a single saw cylinder due to rework is about 0.5-1 hour. After all processes are completed, the disassembly stage begins. First, all locking parts are loosened with a wrench. For tightly fitted saw blades, a pry bar or jack is used to pry them apart. After disassembly, the saw blades are hoisted one by one to the storage rack by an overhead crane, and the saw cylinder is transferred to the cleaning and maintenance station.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were discovered: The existing saw blade disassembly and assembly devices are time-consuming, labor-intensive, and prone to jamming. They require the shaft carrying the saw blade to be transported to a support via a suspension device, and then the bearing seat at the end of the shaft to be removed. After all this is done, the saw blade is manually removed from the shaft. Because the shaft is long and typically has around one hundred saw blades, it cannot be removed all at once. This requires the user to move back and forth to grab and push, a time-consuming and labor-intensive process. Furthermore, because the manual pushing force on the saw blade cannot be guaranteed to be aligned with the shaft's length, the saw blade tilts under the pushing force. This causes the saw blade and shaft to press against each other, increasing friction and preventing the saw blade from being pulled out properly, often resulting in jamming. This severely impacts the efficiency of saw blade disassembly and assembly. Therefore, we propose a saw blade disassembly and assembly device. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a saw blade disassembly and assembly device, which solves the technical problems of existing saw blade disassembly and assembly devices being time-consuming, labor-intensive, and prone to jamming during use.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A saw blade disassembly and assembly device, the disassembly and assembly device comprising: A support bracket for supporting the shaft with the saw blade; The conveying assembly consists of two sets, both mounted on a bracket and located on either side of the shaft, for driving the saw blade to move. The conveying assembly includes a long support frame, and a number of connecting blocks connected in series are embedded in the outer wall of the support frame. A baffle is connected to the outside of the connecting block, and when the shaft with the saw blade is placed on the support, the baffle is inserted into the gap between two adjacent saw blades. The connecting block is driven to rotate by a motor on the support frame, which can move the connecting block and the saw blade located at the front end of the baffle together.

[0007] Preferably, the outer wall of the support frame is provided with a traction groove, and the connecting block is embedded in the traction groove and corresponds to the groove on the inner wall of the traction groove. The connecting block can slide along the extension direction of the traction groove. The baffle is located on the side of the connecting block facing the center of the bracket.

[0008] Preferably, a reserved slot is provided at each of the two ends of the support frame, and the reserved slot is located on the inner side of the support frame. The transmission gear on the motor corresponds to the reserved slot, and the outer wall of the transmission gear passes through the reserved slot and fits against the connecting block on the inner side of the support frame. A rotating shaft is provided at each end of the transmission gear, and the rotating shaft is connected to the inside of the support frame through a bearing. The transmission gear is connected to the output shaft of the motor via a rotating shaft. When the motor is powered on and rotates, the transmission gear can drive the connecting block to move.

[0009] Preferably, the two sides of the rear end of the connecting block are respectively provided with a movable groove and an extension block, and the extension blocks and movable grooves of two adjacent connecting blocks are interlocked. The movable groove has a guide groove on each of its two inner walls, and the guide groove is inserted into the connecting pin on the outer wall of the extension block. The guide groove extends along the width of the connecting block. When two adjacent connecting blocks are stretched, the connecting pin on one extension block slides to the end of the guide groove on the other connecting block.

[0010] Preferably, the connecting block is provided with teeth on the side facing the support frame, and the connecting block engages with the locking teeth on the outer wall of the transmission gear through the teeth. When the transmission gear is rotated by the reserved groove, the connecting block is driven to slide along the extension direction of the traction groove through the locking teeth and teeth on the outer wall of the transmission gear, and pushes the saw blade located at the front end of the baffle to move. The end of the baffle facing the saw blade is arc-shaped and is wrapped with a flexible material.

[0011] Preferably, the end of the shaft is connected to an arc-shaped traction roller, and the end of the traction roller is provided with a docking groove. The traction roller is inserted into the end of the shaft through the docking groove. When the saw blade is conveyed along the shaft, the saw blade enters the traction roller along the shaft.

[0012] Preferably, lifting seats are provided at both ends of the bracket, and the lifting seats correspond to the lifting hydraulic cylinders on the bracket. The lifting seats can be raised and lowered under the drive of the lifting hydraulic cylinders. The bracket has a stop at its center. When the shaft with the saw blade is placed on the bracket, the clamping plate at the top of the stop engages in the gap between two adjacent saw blades, thus restricting the position of the saw blade.

[0013] Preferably, the end of the bracket is provided with a limiting component, and the bearing seat at the end of the shaft is removed by the limiting component. The limiting component includes a bearing rod, and each end of the bearing rod is connected to the side wall of the bracket through a connecting rod. The connecting rod is movably connected to the side wall, and the bearing rod can rotate around the hinge point between the connecting rod and the side wall. The bearing rod is provided with a limiting hydraulic cylinder on the side facing the shaft, and the end of the shaft is squeezed by the limiting hydraulic cylinder.

[0014] (III) Beneficial Effects 1. By employing several sequentially connected connecting blocks as the saw blade conveying structure, when the shaft with the saw blade is installed onto the bracket, the baffles on the connecting blocks insert into the gaps between two adjacent saw blades. Then, the motor drives the connecting blocks to move. At this time, the baffles inserted between the saw blades push the saw blades on the shaft, conveying them in the direction of the connecting blocks' movement. Therefore, workers do not need to move back and forth along the shaft to remove the saw blades. Conversely, when installing the saw blade, by fitting the saw blade onto the shaft and simultaneously controlling the motor to drive the connecting blocks in the opposite direction, each baffle acts as a gripper, hooking the saw blade and conveying it to the other end of the shaft, thus completing the saw blade installation. Therefore, this effectively solves the technical problems of existing saw blade disassembly and assembly devices being time-consuming, labor-intensive, and prone to jamming. It achieves rapid disassembly and installation of the saw blade, thereby improving overall work efficiency and preventing severe wear on the shaft caused by the saw blade, thus improving overall stability and convenience.

[0015] 2. By setting movable grooves and extension plates on both sides of the connecting block, and inserting the extension plate between two adjacent connecting blocks into the movable groove, and the connecting pin on the outside of the extension plate corresponding to the guide groove on the inner wall of the movable groove, the two adjacent connecting plates can be relatively separated. Therefore, when the motor pulls the connecting block, the connecting block unfolds from the side closer to the motor to the side farther away from the motor. Using this method, each saw blade can be driven at once instead of simultaneously. This not only reduces the load on the motor, but also concentrates the force of the motor onto the individual saw blades, so that the saw blades can be loosened and facilitate subsequent conveying. Secondly, an arc-shaped traction roller is connected to the end of the shaft, which can guide the saw blades removed from the shaft to the traction roller, thereby collecting the saw blades. Conversely, the traction roller with the saw blades sleeved on it can be installed on the end of the shaft first, and then rotated 180°, so that the saw blades sleeved on the traction roller enter the shaft under the action of gravity, thereby conveying the saw blades and further reducing the difficulty of saw blade conveying.

[0016] 3. By installing a stop in the middle of the support and inserting it into the gap between the saw blades, the position of the saw blades is restricted. Simultaneously, a connecting rod is hinged to one end of the support, and this connecting rod drives a limit hydraulic cylinder to rotate. Figure 2 As shown in (b) and (c), when the limiting hydraulic cylinder extends, the shaft can be fixed and limited. Thus, only one person is needed to use a wrench to disassemble the bearing seat at the other end of the shaft, thereby reducing the difficulty of disassembly. Attached Figure Description

[0020] This application provides a saw blade assembly / disassembly device that effectively solves the technical problems of existing saw blade assembly / disassembly devices being time-consuming, labor-intensive, and prone to jamming. In existing saw blade assembly / disassembly devices, several sequentially connected connecting blocks are used as the saw blade conveying structure. When the shaft with the saw blade is installed onto the bracket, the baffles on the connecting blocks insert into the gaps between adjacent saw blades. Then, the motor drives the connecting blocks to move. At this time, the baffles inserted between the saw blades push the saw blades on the shaft, conveying them in the direction of the connecting blocks' movement. Therefore, the operator does not need to move back and forth along the shaft to remove the saw blades from the shaft. Conversely, when it is necessary to install the saw blade, the saw blade is fitted onto the shaft, and the motor is controlled to drive the connecting blocks in the opposite direction. Each baffle acts as a gripper, hooking the saw blade and conveying it to the other end of the shaft, thus completing the saw blade installation. This achieves rapid disassembly and installation of the saw blade, improving overall work efficiency and preventing severe wear on the shaft caused by the saw blade, thereby improving overall stability and convenience.

[0021] Example: The technical solution in this application effectively solves the technical problems of existing saw blade assembly and disassembly devices being time-consuming, labor-intensive, and prone to jamming during use. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides a saw blade assembly / disassembly device, which mainly comprises three parts: First, a bracket for supporting various structures, such as the saw blade 22 supporting the shaft 21; Second, a conveying structure, mounted on the bracket, consisting of two sets, respectively positioned on both sides of the shaft 21, which clamps the saw blade 22 outside the shaft 21. A motor 53 then powers the conveying structure on the bracket, causing it to move the saw blade 22 mounted on the shaft 21. The saw blade 22 can be installed or removed simply by controlling the direction of the conveying structure; Third, a limiting component 3 for removing the bearing at the end of the shaft 21. This component restricts the movement of the shaft 21 by clamping and limiting the movement, allowing one person to remove the bearing from one end of the shaft 21 using a hand tool. The overall structure is simple and convenient. The specific structure is as follows: The support frame mainly consists of two parallel steel plates and a horizontal plate connecting the two steel plates, such as... Figure 1 As shown, the structure is a base 11, and the base 11 is provided with two sets of corresponding side walls 12, providing movement space for the subsequent lifting seat 16. The lifting seat 16 is positioned between the two corresponding side walls 12. To ensure the stability of the vertical movement of the lifting seat 16, two pulleys are provided at each end of the lifting seat 16, and the pulleys correspond to the grooves on the side walls 12, as shown. Figure 1As shown, during the up-and-down movement of the lifting seat 16, the pulleys at both ends of the lifting seat 16 move along the slide groove, thereby guiding the lifting and lowering of the lifting seat 16. To ensure the stability of the movement of the lifting seat 16, a lifting hydraulic cylinder 13 is used as the lifting power source for the lifting seat 16. When the lifting hydraulic cylinder 13 extends, it can drive the lifting seat 16 to rise and fall. The reason for setting up the lifting structure is to lift the shaft 21 by connecting the saw blade 22 with the stop 4 and the bearing seat 24 with the top position of the lifting seat 16, so that after the alignment is completed, the shaft 21 carrying the saw blade 22 can be lowered to the designated position. Secondly, the two opposite side walls 12 are connected by side rods 14, and in order to limit and protect the placed saw blade 22, multiple protective arms 15 are connected by hinges. Therefore, by flipping the protective arms 15, the protective arms 15 can be covered on the saw blade 22. Figure 5 As shown, the protective arm 15 can protect the saw blade 22 in this way; A stop 4 is set at the center of the base 11. The stop 4 is inserted into the gap between the saw blades 22 to restrict the movement of the saw blades 22. The stop 4 consists of a positioning seat 41 on the base 11 and a clamping plate 43 set on the positioning seat 41. The positioning seat 41 is connected to the base 11 through a slide rail. Therefore, the positioning seat 41 can be slid as needed to move the positioning seat 41. In order to ensure the stability of the clamping plate 43, ribs 42 are set on both sides of the clamping plate 43 to improve the firmness of the fixation between the clamping plate 43 and the positioning seat 41. That is, when the shaft 21 with the saw blades 22 is placed on the lifting seat 16, the clamping plate 43 at the top of the stop 4 is inserted into the gap between two adjacent saw blades 22 to cooperate with the limiting structure, thereby clamping and fixing the saw blades 22.

[0022] The limiting structure, namely the limiting component 3, is disposed between one set of two sidewalls 12, such as... Figure 1 and Figure 2 As shown, the bearing seat 24 at the end of the shaft 21 is removed by the limiting assembly 3. The limiting assembly 3 includes a bearing rod 31 for supporting the limiting hydraulic cylinder 33, and each end of the bearing rod 31 is hinged to the side wall 12 of the bracket via a connecting rod 32. Therefore, the bearing rod 31 can rotate around the hinge point between the connecting rod 32 and the side wall 12 as an axis. Figure 2 As shown in (a) and (b), in use, the first step is to flip the bearing rod 31, causing it to flip together with the limiting hydraulic cylinder 33, so that the limiting hydraulic cylinder 33 aligns with the end of the shaft 21. Then, the limiting hydraulic cylinder 33 is extended. When the limiting hydraulic cylinder 33 extends, the mating disc 34 on its telescopic end presses against the end of the shaft 21, as shown in (a) and (b). Figure 2As shown in (c), since the middle part of the saw blade 22 is inserted by the stop 4, the saw blade 22 is fixed between the stop 4 and the limiting hydraulic cylinder 33, thereby restricting the movement of the saw blade 22. In this way, only one person needs to use a hand tool to disassemble the bearing seat 24 at the other end of the shaft 21 (the end away from the limiting component 3) to remove the saw blade 22 from the shaft 21.

[0023] The conveying structure, namely conveying component 5, is also a significant improvement. Compared to traditional manual handling, we use two sets of conveying structures to clamp the saw blade 22, forming grippers that hold the saw blade 22 located on the shaft 21 outwards. Power is then provided by the motor 53 to convey the saw blade 22 outwards, thus removing it from the shaft 21. A linkage 55 is used for traction, and the specific structure is as follows: Two parallel, elongated support frames 51 serve as support components for the conveying structure. A circumferential traction groove is formed on the outer wall of each support frame 51. Figure 8 The enlarged view shows that several connecting blocks 551 are then embedded inside the traction groove, with the upper and lower ends of the connecting blocks 551 corresponding to the grooves on the inner wall of the traction groove, thereby limiting the range of motion of the connecting blocks 551. Therefore, the connecting blocks 551 can slide along the extension direction of the traction groove without sliding out of the traction groove. Adjacent connecting blocks 551 are connected in series to form a chain, so that the subsequent motor 53 can drive the connecting blocks 551 to move. Among them, a baffle 552 is connected to the outer side of the connecting block 551, such as Figure 9 and Figure 10As shown, the baffle 552 extends towards the center of the base 11, and the thickness of the connecting block 551 is consistent with the gap between two adjacent saw blades 22. To ensure that the distance between adjacent saw blades 22 does not overlap, a ring is fitted between the two saw blades 22 during installation, thus separating them. Therefore, when the shaft 21 with the saw blades 22 is placed on the bracket, the baffle 552 can be inserted into the gap between the two adjacent saw blades 22. Furthermore, the end of the baffle 552 facing the saw blade 22 is arc-shaped and wrapped with a flexible material to reduce collisions between the baffle 552 and the saw blade 22. To ensure that the baffle 552 can be stably and accurately inserted into the gap between the two adjacent saw blades... The gap between the saw blades 22 is such that a locking block 56 is set in the traction groove on the outer wall of the support frame 51. Therefore, when the connecting block 551 at the end is in contact with the locking block 56, the gap between the baffle 552 on the connecting block 551 and the saw blade 22 corresponds. So when the saw blade 22 is placed, the baffle 552 can be stably and accurately inserted into the gap of the saw blade 22, thereby ensuring that the starting position of the baffle 552 is constant. Then, the connecting block 551, which is connected in a chain shape, is driven by the motor 53, which can drive the connecting block 551 and the saw blade 22 located at the front end of the baffle 552 to move together. The baffle 552 is used to squeeze the saw blade 22 and push the saw blade 22 toward the end of the shaft 21, so as to complete the disassembly or installation of the saw blade 22.

[0024] However, a problem was discovered during use: when the motor 53 drives the connecting block 551 to rotate, since the distance between them is the same as the distance between the saw blades 22, all the saw blades 22 move together during operation. This not only places an excessive load on the motor 53, but also, because the saw blades 22 are tightly fixed together and to the shaft 21, further increases the load and can easily scratch the shaft 21. To address this, we provided movable slots and extension blocks 553 on both sides of the connecting block 551, with the extension blocks 553 and movable slots of adjacent connecting blocks 551 interlocking. Each inner wall of the movable slot has a guide groove 555, which interlocks with the connecting pin 556 on the outer wall of the extension block 553. The guide grooves 555 extend along the width of the connecting block 551. Therefore, when two adjacent connecting blocks 551 are stretched, the connecting pin 556 on one extension block 553 slides to the end of the guide groove 555 on the other connecting block 551. Thus, the two adjacent connecting blocks 551 can slide against each other. When one is pulled, it does not immediately transmit power to the other adjacent connecting block 551. Instead, it moves only after being pulled a certain distance. Utilizing this characteristic, when the motor 53 moves the connecting blocks 551, the torque of the motor 53 is transmitted sequentially through the connecting blocks 551. Therefore, the force exerted by the motor 53 on the saw blade 22 is transmitted sequentially, preventing the simultaneous movement of all saw blades 22. This reduces the instantaneous load on the motor 53 while also loosening the saw blade 22 from the shaft 21, facilitating subsequent transportation. Figure 9 and Figure 10 As shown.

[0025] Power transmission process: We use gear drive. To ensure stable conveying and retraction of the chain-connected connecting blocks 551, the gear drive structure is positioned at the end of the support frame 51. Therefore, during operation, the gear drive mechanism operates from the end connecting block 551; and during retraction, it starts from the beginning, facilitating stable conveying. First, a transmission gear 52 is installed on the inner side of the support frame 51, near both ends. To facilitate the engagement of the transmission gear 52 with the connecting blocks 551 sleeved on the outside of the support frame 51, a pre-drilled slot 54 is provided at each end of the support frame 51. Figure 8 As shown, the transmission gear 52 can pass through the reserved slot 54 and fit against the connecting block 551 inside the support frame 51. Bearings are used to reinforce the transmission gear 52; that is, a rotating shaft is provided at each end of the transmission gear 52, and the rotating shafts are connected to the inside of the support frame 51 via bearings. The transmission gear 52 is connected to the output shaft of the motor 53 via the rotating shafts. Therefore, when the motor 53 is energized and rotates, the connecting block 551 can be moved via the transmission gear 52. Furthermore, as... Figures 11 to 13As shown, in order to stably transmit power to the connecting block 551 when the transmission gear 52 rotates, teeth 554 are provided on the back of the connecting block 551 (i.e., the side facing the support frame 51). The teeth 554 mesh with the retaining teeth on the outer wall of the transmission gear 52. Therefore, when the reserved groove 54 drives the transmission gear 52 to rotate, the retaining teeth on the outer wall of the transmission gear 52 and the teeth 554 can drive the connecting block 551 to slide along the extension direction of the traction groove and push the saw blade 22 located at the front end of the baffle 552 to move. Moreover, the transmission gear 52 is located at the far end position, which can drive the saw blade 22 from the end position closest to the shaft 21, thereby pulling the saw blade 22 from near to far.

[0026] Secondly, to facilitate the collection of the saw blade 22, an arc-shaped traction roller 23 is provided at the end of the shaft 21, such as... Figure 2 and Figure 3 As shown, the end of the traction roller 23 has a mating groove that matches the shape of the end of the shaft 21. The traction roller 23 is inserted into the end of the shaft 21 through the mating groove. Therefore, when the saw blade 22 is conveyed along the shaft 21, the saw blade 22 enters the traction roller 23 along the shaft 21 and thus accumulates on the traction roller 23.

[0027] In the specific implementation process, the first step is to control the lifting equipment to move the shaft 21 with the saw blade 22 above the device, and align the bearing seats 24 at both ends of the shaft 21 with the lifting seats 16 on the device vertically. Figure 3 As shown, the saw blade 22 and the clamping plate 43 on the stop 4 are vertically aligned. Then, the saw blade 22 is oriented so that the bearing seat 24 on the shaft 21 is placed on the lifting seat 16. At this time, the clamping plate 43 is inserted into the gap between the saw blades 22, thereby restricting the center position of the saw blade 22. At the same time, the baffles 552 on the support frame 51 are inserted sequentially (that is, the control motor 53 presses the sequentially connected connecting blocks 551 together, at which time the gap between the baffles 552 on the connecting block 551 and the saw blade 22 corresponds). Then, as... Figure 2 As shown in (a), the bearing rod 31 with the limiting hydraulic cylinder 33 is lifted, and the limiting hydraulic cylinder 33 is aligned with the end of the shaft 21, as shown in (a). Figure 2 As shown in (b), the support rod 31 can also be lifted using a lifter or similar device. After completion, the limit hydraulic cylinder 33 is extended to bring the mating plate 34 into contact with the end of the shaft 21, as shown in (b). Figure 2 As shown in (c), the end of the shaft 21 is locked and corresponds to the clamping plate 43 inserted in the middle of the saw blade 22, thereby clamping the saw blade 22. Then the bearing seat 24 at the other end of the shaft 21 can be removed by using a tool. The second step, after the bearing seat 24 at the end of the shaft 21 is disassembled, is to install the bent traction roller 23 onto the end of the shaft 21, forming a shape as shown in the image. Figure 1As shown in the diagram, the lifting seat 16 at the desired detachment end can then be lowered, as... Figure 4 As shown, at this time, the saw blade 22 is supported by the clamping plate 43 and the lifting seat 16 at the other end, while the other end is supported by the traction roller 23, thereby ensuring the stability of the shaft 21. The control motor 53 drives the transmission gear 52 (the motor 53 on the side closer to the traction roller 23). Since the teeth on the outside of the transmission gear 52 mesh with the teeth 554 on the inside of the connecting block 551, when the motor 53 drives the transmission gear 52 to rotate, it can drive the connecting block 551 at the very end to move towards the support frame 51. Also, since the connecting block 551 is inserted into the traction groove on the inside of the support frame 51, when the connecting block 551 is driven by the transmission gear 52, it can push the connecting block 551 to the other side of the traction groove, such as... Figures 9 to 10 As shown; In this design, the extension blocks 553 and movable slots of two adjacent connecting blocks 551 are interlocked. Therefore, when two adjacent connecting blocks 551 are stretched, the connecting pin 556 on one extension block 553 slides to the end of the guide slot 555 on the other connecting block 551. Thus, the two adjacent connecting blocks 551 can slide against each other. When one is pulled, it does not immediately transmit power to the other adjacent connecting block 551; instead, it moves only after being pulled a certain distance. Utilizing this characteristic, when the motor 53 drives the connecting blocks 551 to move, the torque of the motor 53 is transmitted sequentially backward through the connecting blocks 551. The force exerted by the motor 53 on the saw blade 22 is transmitted sequentially, preventing the simultaneous movement of all saw blades 22. This reduces the instantaneous load on the motor 53 and allows the saw blade 22 to loosen from the shaft 21, facilitating subsequent transportation. As a result, the saw blade 22 is pushed from the shaft 21 onto the traction roller 23. Since the saw blade 22 with the shaft 21 located on one side of the clamping plate 43 is being removed, the weight at that end (the end from which the saw blade 22 is being removed) decreases during removal, causing the other end to rotate about the clamping plate 43 as the axis. However, since the other end is supported by the lifting seat 16, although the weight changes, the shaft 21 will not move until the saw blade 22 at that end is completely removed. The third step is to install the saw blade 22 to be processed. The saw blade 22 is placed on the traction roller 23, and then the traction roller 23 is rotated 180°, that is, the end of the traction roller 23 faces upward. At this time, the saw blade 22 placed on the traction roller 23 falls onto the shaft 21 under the action of gravity. Then, the motor 53 is controlled to rotate in the direction, thereby pulling the saw blade 22 onto the shaft 21 one by one until the connecting block 551 at the end moves to the position of the locking block 56. The movement position of the connecting block 551 is restricted by the blocking block 56, so that the connecting blocks 551 are neatly arranged together. At this time, the saw blade 22 placed on the shaft 21 is also tightly arranged, thus completing the installation of the saw blade 22. With the installation of the saw blade 22 at this end, the weight component at this end of the shaft 21 increases, which facilitates the subsequent disassembly of the saw blade 22 at the other end of the shaft 21. Fourth, the saw blade 22 on the other side of the shaft 21 is disassembled using the method described above.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
