Description

Technical Field

[0001] This application relates to the field of grinding equipment, and more particularly to a gear grinding machine. Background Technology

[0002] A gear grinding machine is a device that uses a grinding wheel as an abrasive to grind the front angle, back angle, and side of the blade where it is connected to the saw blade. It is mainly used to reduce the deformation of the saw blade after heat treatment and to improve the processing accuracy of the saw blade.

[0003] Currently used gear grinding machines generally include a rear angle grinder, a front angle grinder, a side grinder, and a feeding assembly. The feeding assembly typically uses a robotic arm in conjunction with an electromagnet to move and feed the saw blade. The hopper for holding unground saw blades is usually a cylindrical rod. The saw blade is fitted onto the outside of this rod. When feeding is needed, the robotic arm drives the electromagnet to move closer to the cylindrical rod, thereby attracting and gripping the saw blade.

[0004] However, the above structure can easily lead to a situation where, during the process of the electromagnet gripping a single saw blade, its strong magnetic force can cause other saw blades on the cylindrical rod to move, resulting in excess material. Summary of the Invention

[0005] In order to achieve a single saw blade grinding operation, this application provides a gear grinding machine.

[0006] The gear grinding machine provided in this application adopts the following technical solution:

[0007] A gear grinding machine includes several grinding machines, one of which has a processing bin on one side. A robotic arm is provided between the processing bin and the back angle grinding machine. The robotic arm is used to drive a saw blade in the processing bin to move closer to the grinding machine.

[0008] The processing hopper includes a feeding tray, a feeding rod is fixedly connected to one side of the feeding tray, and several sliding rails are fixedly connected to the side wall of the feeding tray. Each sliding rail is slidably connected to a blade ruler for limiting the saw blade on the feeding rod.

[0009] The processing hopper is connected to a segmentation assembly to limit the number of saw blades that the robotic arm can grasp at one time.

[0010] By adopting the above technical solution, when the saw blade needs to be ground, the saw blade is placed in the processing bin, and then a robotic arm is used to pick up the saw blade from the processing bin. During the process of the robotic arm picking up the material, the segmentation component limits the amount of material picked up by the robotic arm at one time, reducing the phenomenon that the robotic arm picks up more than one saw blade at a time, which would affect the grinding effect of the picked-up saw blade.

[0011] Optionally, the slitting assembly includes a slitting support plate connected to the feeding tray and capable of moving radially along the feeding tray. Multiple slitting blocks are connected to the slitting support plate via slitting tension springs. Each slitting block can move toward the feeding tray, and the side of each slitting block closest to the feeding tray can abut against the saw blade.

[0012] By adopting the above technical solution, when the robot arm grabs the saw blade, the segmented abutment block abuts against the saw blade. When the robot arm continues to move the saw blade, the segmented abutment block separates from the saw blade currently grabbed by the robot arm, and under the action of the segmented tension spring, it abuts against the saw blade on the side of the feeding rod away from the feeding plate, thereby limiting the number of saw blades that the robot arm can grab in a single operation.

[0013] Optionally, the segmentation assembly includes multiple segmentation support plates evenly distributed around the feeding tray. The multiple segmentation support plates simultaneously limit the saw blade on the feeding rod. Each segmentation support plate is connected to multiple segmentation plate groups. The segmentation plates in each segmentation plate group are used to limit the position of a single saw blade. Multiple segmentation plates in the same segmentation plate group are connected to a linkage component. The linkage component can drive the remaining segmentation plates to move when a single segmentation plate moves within the same segmentation plate group.

[0014] By adopting the above technical solution, during use, the position of each saw blade is restricted by the segmented plate group connected to the segmented support plate. Furthermore, through the interaction of the linkage components, after the robotic arm grabs the current saw blade, the linkage components drive the remaining segmented plates to block the remaining saw blades, thereby restricting the position of the saw blades.

[0015] Optionally, the segmented plate assembly includes a first segmented plate, a second segmented plate, and a third segmented plate. One side of the first segmented plate, the second segmented plate, and the third segmented plate is used to abut against the saw blade. The end of the second segmented plate away from the saw blade it abuts against is rotatably connected to the side wall of the adjacent segmented support plate and slides along its own length. The end of the third segmented plate away from the saw blade it abuts against is rotatably connected to the side wall of the adjacent segmented support plate and slides along its own length.

[0016] By adopting the above technical solution, in the initial state, the first segment plate abuts against the adjacent saw blade. At this time, the second and third segment plates are located inside the segment support plate. When the saw blade abutted by the first segment plate is grabbed, the first segment plate and the grabbed saw blade move simultaneously, and the linkage component drives the second segment plate to abut against the adjacent saw blade, thereby limiting the number of saw blades grabbed by the robot arm each time.

[0017] Optionally, the end of the first segmenting plate near the segmenting support plate is rotatably connected to the segmenting support plate, and the side of the first segmenting plate away from the saw blade is rotatably connected to a first connecting rod, which is bent and rotatably connected to the end of the second segmenting plate away from the saw blade.

[0018] The second segment plate is rotatably connected to a second link at one end of the first link. The second link is bent, and the end of the second link away from the second segment plate is rotatably connected to a third segment plate.

[0019] By adopting the above technical solution, when the first segment plate rotates under the drive of the saw blade, the first segment plate drives the second segment plate to abut against the adjacent saw blade through the first connecting rod. When the second segment plate rotates under the drive of the saw blade, the second segment plate drives the third segment plate to abut against the adjacent saw blade through the second connecting rod, thereby limiting the number of saw blades that the robot arm can grab at one time.

[0020] Optionally, a reset motor for driving the first segment plate to rotate is connected to one side of the first segment plate.

[0021] By adopting the above technical solution, when all saw blades have been ground and re-filled, the first segmenting plate is rotated by turning on the reset motor. The first segmenting plate moves the second segmenting plate into the segmenting support plate through the first connecting rod. The second segmenting plate moves the third segmenting plate into the segmenting support plate through the second connecting rod, thereby reducing the need for workers to reset the segmenting plates.

[0022] Optionally, the linkage component includes a first gear pair connected to the rotating end of the first segment plate, a first rack connected to one side of the first gear pair, and the first rack being rotatably connected to the rotating end of the second segment plate.

[0023] The rotating end of the second segment plate is connected to a second gear pair, the second gear pair is connected to a second rack, and the second rack is rotatably connected to the rotating end of the third segment plate.

[0024] By adopting the above technical solution, when the first segmented plate rotates under the drive of the saw blade, the first segmented plate drives the second segmented plate to move and abut against the adjacent saw blade through the first gear pair and the first rack. When the second segmented plate rotates under the drive of the saw blade, the second segmented plate drives the third segmented plate to abut against the adjacent saw blade through the second gear pair and the second rack, thereby limiting the number of saw blades that the robot arm can grab at one time.

[0025] Optionally, the first gear pair includes a first drive gear fixedly connected to the first segment plate, a first intermediate gear meshing on one side of the first drive gear, a first driven gear meshing on one side of the first intermediate gear, and the first driven gear meshing with the first rack.

[0026] By adopting the above technical solution, the first drive gear rotates during the rotation of the first segment plate, and the first drive gear rotates during the rotation of the first drive gear through the first intermediate wheel, and the first driven gear rotates during the rotation of the first rack and the second segment plate.

[0027] Optionally, the second gear pair includes a second drive gear, and a drive rod is slidably inserted into the side wall of the second segment plate near the second drive gear. The drive rod can be inserted into the second drive gear when the second segment plate abuts against the saw blade and drive the second drive gear to rotate during the rotation of the second segment plate. A second intermediate wheel is meshed on one side of the second drive gear, and a second driven gear is meshed on one side of the second intermediate wheel. The second driven gear meshes with the second rack.

[0028] By adopting the above technical solution, when the second segment plate moves to the position of abutting against the saw blade on one side, the drive rod connected to the second segment plate is inserted into the second drive gear. Then, when the second segment plate rotates under the drive of the saw blade, the second segment plate drives the second drive gear to rotate. During the rotation of the second drive gear, the second drive gear drives the second intermediate wheel to rotate. During the rotation of the second intermediate wheel, the second driven gear drives the second driven gear to rotate. The second driven gear and the second rack drive the third segment plate to abut against the adjacent saw blade.

[0029] Optionally, a recovery motor for driving the first segment plate to rotate is connected to one side of the first segment plate, and a reset member is connected between the first segment plate and the third segment plate. The reset member can drive the third segment plate to move into the segment support plate as the first segment plate rotates toward the feeding tray.

[0030] By adopting the above technical solution, when it is necessary to reset the first segment plate, the second segment plate, and the third segment plate, the reset motor is turned on to drive the first segment plate to rotate. During the rotation, the first segment plate drives the second segment plate to move into the segment support plate through the interaction of gears and racks. At the same time, the first segment plate drives the third segment plate to move into the segment support plate through the reset component, thereby realizing the reset operation of the first segment plate, the second segment plate, and the third segment plate.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] By setting up a segmentation component, the number of saw blades that the robotic arm can grasp at one time can be limited, thus facilitating the saw blade processing process.

[0033] By setting up linkage components, it is convenient for subsequent segment plates to move and limit the saw blade during the movement of a single segment plate.

[0034] By setting up a reset motor, a recovery motor, and a reset component, it is possible for staff to easily perform reset operations on the first, second, and third segment plates. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail.

[0044] This application discloses a gear grinding machine. Example 1

[0045] Reference Figure 1 , Figure 2 and Figure 3 A gear grinding machine includes a frame 1, inside which a side grinder 2, a front angle grinder 3, and a rear angle grinder 4 are arranged sequentially. A robot arm 5 is provided on the side of the rear angle grinder 4 away from the front angle grinder 3. Two horizontally arranged guide rails 11 are provided on the upper side of the frame 1, and the two guide rails 11 are arranged opposite each other. A drive component 51 for driving the robot arm 5 to slide along the length direction of the guide rails 11 is connected to the upper end. A processing bin 6 is provided on the side of the robot arm 5 away from the rear angle grinder 4.

[0046] In this embodiment, the processing hopper 6 includes two spaced-apart loading trays 61, each vertically arranged. A loading rod 62 is fixedly connected to the center of each loading tray 61, and each loading rod 62 is perpendicular to the connected loading tray 61. Each loading tray 61 is fixedly connected to several sliding rails 63 along its radial direction; in this embodiment, each loading tray 61 is connected to one sliding rail 63. Each sliding rail 63 is slidably connected to a saw blade 64 along its length, and each saw blade 64 is perpendicular to the connected sliding rail 63 and can simultaneously abut against multiple saw blades on the connected loading rod 62. Each loading rod 62 has a finished product rod 65 on one side, parallel to the loading rod 62.

[0047] Each feeding tray 61 is connected to a slitting assembly 7, which is used to slitting the saw blade on the feeding rod 62.

[0048] When the saw blade needs to be sharpened, it is placed on the loading bar 62 and abutted against by the blade ruler 64. Then, the robotic arm 5 picks up the saw blade from the loading bar 62. During this process, the blade-splitting assembly 7 limits the robotic arm 5 to picking up only one blade at a time. The robotic arm 5 then moves the saw blade to the side grinder 2, the front angle grinder 3, and the rear angle grinder 4 for sharpening.

[0049] By setting the segmentation component 7 to limit the number of saw blades that the robotic arm 5 can pick up at one time, the phenomenon that the saw blade grinding is affected by the robotic arm 5 picking up more than one saw blade at a time is reduced.

[0050] The robotic arm 5 includes a vertically arranged lifting arm 52, which is connected to a drive unit 51. The lower end of the lifting arm 52 is capable of lifting and lowering. The lifting and lowering operation of the lifting arm 52 can be achieved by various drive sources such as hydraulic cylinders, pneumatic cylinders, and electric actuators. In this embodiment, the lifting arm 52 is driven by an electric actuator. A rotating arm 53 is connected to the lower end of the lifting arm 52. The rotating arm 53 is rotatably connected to the lifting arm 52 and can rotate independently. The rotating arm 53 is driven by a motor. Multiple electromagnetic blocks 54 are mounted on the rotating arm 53, each of which is used to grip the saw blade.

[0051] When a saw blade needs to be gripped by a robotic arm for grinding, the drive unit 51, in conjunction with the lifting arm 52 and the rotating arm 53, moves the electromagnetic block 54 to one side of the saw blade. Then, the electromagnetic block 54 is fitted onto the outside of the loading rod 62 and energized, causing it to attract and grip the saw blade on the loading rod 62. After grinding is complete, the robotic arm moves the electromagnetic block 54 and the gripped saw blade onto the outside of the finished product rod 65. At this point, the electromagnetic block 54 is de-energized, causing the saw blade to fall onto the finished product rod 65, thus completing the saw blade unloading operation.

[0052] The segmentation assembly 7 includes multiple segmentation slide rails 71 fixedly connected to the feeding tray 61. In this embodiment, two segmentation slide rails 71 are arranged opposite each other, and each segmentation slide rail 71 is radially distributed along the feeding tray 61. Each segmentation slide rail 71 is slidably connected to a segmentation support plate 72 along its length. Each segmentation support plate 72 is perpendicular to the connected segmentation slide rail 71, and each segmentation support plate 72 can simultaneously abut against multiple saw blades on one side of the feeding rod 62. Each segmentation slide rail 71 is threaded with a lead screw. One end of the lead screw passes through the segmentation slide rail 71 and abuts against the side of the segmentation support plate 72 away from the feeding rod 62. Since the lead screw is a conventional structure and not a major innovation of this application, it is not shown in the accompanying drawings.

[0053] Each segmented support plate 72 is slidably connected with multiple segmented abutment blocks 73 along its own length. In this embodiment, each segmented support plate 72 is connected with three segmented abutment blocks 73, and the three segmented abutment blocks 73 are arranged side by side. Each segmented abutment block 73 is connected to a segmented tension spring 74 at one end near the segmented support plate 72. Each segmented tension spring 74 is used to drive the connected segmented abutment block 73 to move towards the connected feeding tray 61.

[0054] After the saw blade is fitted onto the outside of the feeding rod 62, the movable segment support plate 72 abuts against the saw blade, and the segment abutment block 73 abuts against the saw blade on the side away from the feeding plate 61. During the process of the robot arm 5 picking up the saw blade, the segment abutment block 73 abuts against the saw blade and moves simultaneously with the saw blade. When the saw blade driven by the electromagnetic block 54 disengages from the segment abutment block 73, the segment abutment block 73, driven by the segment tension spring 74, abuts against the remaining saw blades away from the feeding plate 61, thereby limiting the number of saw blades picked up by the robot arm 5 each time.

[0055] The implementation principle of Example 1 is as follows: A robotic arm grasps the saw blade, and during the grasping process, the number of saw blades grasped by the robotic arm at one time is limited by the segmentation component 7. Then, the robotic arm moves the saw blade to the side grinder 2, the front angle grinder 3, and the rear angle grinder for grinding, thereby realizing the grinding operation of the saw blade. Example 2

[0056] Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that each segment support plate 72 has multiple segment plate groups 75 evenly arranged and connected along its own length direction. The segment plate groups 75 are used to abut against different saw blades respectively. The segment plate groups 75 are connected to a linkage component 76, which is used to drive the adjacent segment plates to move when one segment plate in the segment plate group 75 moves.

[0057] In actual use, different slit plates abut against the saw blade. As the electromagnetic block 54 moves the abutting saw blade, the saw blade moves the abutting slit plate. When the slit plate moves, the linkage component 76 moves the remaining slit plates and restricts the position of the remaining saw blades that are far away from the feeding plate 61, thereby limiting the number of saw blades that the electromagnetic block 54 can pick up at one time.

[0058] Each segmentation plate assembly 75 includes a first segmentation plate 751, a second segmentation plate 752 on the side of each first segmentation plate 751 near the connected feeding tray 61, and a third segmentation plate 753 on the side of each second segmentation plate 752 near the connected feeding tray 61. The end of each first segmentation plate 751 near the segmentation support plate 72 is rotatably connected to the segmentation support plate 72, and the segmentation support plate 72 has a groove inside for accommodating the first segmentation plate 751.

[0059] The second segment plate 752 is inserted into the segment support plate 72 in a direction perpendicular to the segment support plate 72, and the end of the second segment plate 752 near the segment support plate 72 is slidably connected to the segment support plate 72. The segment support plate 72 has a groove inside for accommodating the second segment plate 752 to rotate within the segment support plate 72. After each end of the second segment plate 752 is removed from the segment support plate 72, it can abut against the side of the adjacent saw blade away from the feed tray 61, and at this time, the end of the second segment plate 752 near the segment support plate 72 is rotatably connected to the inner wall of the segment support plate 72.

[0060] The third segment plate 753 is inserted into the segment support plate 72 in a direction perpendicular to the segment support plate 72, and the end of the third segment plate 753 near the segment support plate 72 is slidably connected to the segment support plate 72. The segment support plate 72 has a groove inside for accommodating the third segment plate 753 to rotate and be placed inside the segment support plate 72. After the end of each third segment plate 753 is removed from the segment support plate 72, it can abut against the side of the adjacent saw blade away from the feed tray 61, and at this time, the end of the third segment plate 753 near the segment support plate 72 is rotatably connected to the inner wall of the segment support plate 72.

[0061] The linkage assembly 76 includes a first connecting rod 761 rotatably connected to the middle position of each first segment plate 751 on the side away from the feeding tray 61. The end of the first connecting rod 761 away from the first segment plate 751 is bent toward the side closer to the adjacent second connecting rod 762. The end of each first connecting rod 761 away from the connected first segment plate 751 is rotatably connected to the end of the adjacent second segment plate 752 that is inserted into the segment support plate 72.

[0062] Each second segment plate 752 is rotatably connected to a second connecting rod 762 on the side away from the feeding tray 61. The end of the second connecting rod 762 away from the connected second segment plate 752 is bent towards the feeding tray 61. The end of the second connecting rod 762 away from the connected second segment plate 752 is rotatably connected to the end of the adjacent third segment plate 753 that is inserted into the segment support plate 72.

[0063] In actual use, the first segmenting plate 751 abuts against the saw blade on the side away from the feed tray 61. Then, when the electromagnetic block 54 attracts the saw blade on the side away from the feed tray 61, the robotic arm 5, in conjunction with the electromagnetic block 54, moves the saw blade away from the feed tray 61. During this movement, the saw blade causes the first segmenting plate 751 to rotate. As the first segmenting plate 751 rotates, it causes the second segmenting plate 752 to move outward from the segmenting support plate 72, making it abut against adjacent saw blades. This limits the number of saw blades that the electromagnetic block 54 can attract at one time.

[0064] When the electromagnetic block 54 drives the second segment plate 752 to move against the saw blade, the second segment plate 752 rotates into the segment support plate 72 under the drive of the saw blade. At this time, the second segment plate 752 drives the third segment plate 753 to move through the second connecting rod 762 and makes the third segment plate 753 abut against the adjacent saw blade, thereby realizing the limiting operation of the subsequent saw blade.

[0065] Each first segment plate 751 is connected to a reset motor 77 on one side. Each reset motor 77 is used to drive the connected first segment plate 751 to rotate. When the reset motor 77 is turned off, the first segment plate 751 can rotate independently of the reset motor 77.

[0066] When subsequent saw blade processing operations are required, the saw blade is fitted onto the feeding rod 62. Then, the first segmenting plate 751 is rotated by the reset motor 77 and comes into contact with the adjacent saw blade. During the rotation of the first segmenting plate 751, the third segmenting plate 753 and the second segmenting plate 752 are rotated and moved into the segmenting support plate 72.

[0067] The implementation principle of Example 2 is as follows: When it is necessary to take the saw blade on the feeding rod 62, the saw blade moves and drives the first dividing plate 751 to move. The first dividing plate 751 moves and drives the second dividing plate 752 to block the adjacent saw blade, thereby realizing the limitation operation on the number of saw blades attracted by the electromagnetic block 54.

[0068] After the saw blades on the feeding rod 62 are removed, the required grinding saw blades are placed on the feeding rod 62. Then, the reset motor 77 is turned on to drive the first segment plate 751, the second segment plate 752 and the third segment plate 753 to return to their initial positions. Example 3

[0069] Reference Figure 6 and Figure 7 The difference between this embodiment and Embodiments 1 and 2 is that the linkage component 76 includes a first gear pair 763 connected to the first segment plate 751. A first rack 764 is connected to one side of the first gear pair 763, and the first gear pair 763 can drive the first rack 764 to move during the rotation of the first segment plate 751. The length direction of the first rack 764 is parallel to the length direction of the second segment plate 752. The side of the first rack 764 closest to the second segment plate 752 is rotatably connected to the second segment plate 752.

[0070] The second segment plate 752 is connected to a second gear pair 765, and a second rack 766 is connected to one side of the second gear pair 765. The second gear pair 765 can drive the second rack 766 to move during the rotation of the second segment plate 752. The second rack 766 is arranged parallel to the third segment plate 753. The side of the second rack 766 closest to the third segment plate 753 is rotatably connected to the third segment plate 753.

[0071] During the movement of the saw blade driven by the electromagnetic block 54, the saw blade drives the first saw blade plate 751 to rotate. As the first saw blade plate 751 rotates, it drives the first rack 764 to move via the first gear pair 763. The first rack 764, in turn, drives the second saw blade plate 752 to move and abut against the adjacent saw blade. The saw blade abutting against one side of the second saw blade plate 752 drives the second saw blade plate 752 to rotate. During this rotation, the second saw blade plate 752 drives the second rack 766 to move via the second gear pair 765. The second rack 766, in turn, drives the third saw blade plate 753 to move and abut against the adjacent saw blade, thus achieving the limiting operation for subsequent saw blades.

[0072] The first gear pair 763 includes a first drive gear 7631 fixedly sleeved on the first segment plate 751 and inserted into one side of the segment support plate 72. A first intermediate gear 7632 meshes with one side of the first drive gear 7631, and a first driven gear 7633 meshes with one side of the first intermediate gear 7632. The first driven gear 7633 is located on the upper side of the first rack 764 and meshes with the first rack 764.

[0073] During the rotation of the first segment plate 751, the first segment plate 751 drives the first drive gear 7631 to rotate. During the rotation of the first drive gear 7631, the first drive gear 7631 drives the first intermediate gear 7632 to rotate. During the rotation of the first intermediate gear 7632, the first driven gear 7633 drives the first rack 764 to move.

[0074] The second gear pair 765 includes a second drive gear 7651 located on one side of the second segment plate 752, with the rotation axis of the second drive gear 7651 coinciding with that of the second segment plate 752. A drive rod 7521 is slidably inserted into the side of the second segment plate 752 near the second drive gear 7651. A drive spring 7522 is fixedly connected between the end of the drive rod 7521 inserted into the interior of the second segment plate 752 and the inner wall of the opposite segment plate 752. A groove for inserting the drive rod 7521 is provided in the middle of the second drive gear 7651. The vertical cross-section of each drive rod 7521 is rhomboid, and the outer wall of each drive rod 7521 can abut against the inner wall of the groove of the second drive gear 7651.

[0075] The second drive gear 7651 is meshed with the second intermediate gear 7652 on one side, and the second intermediate gear 7652 is meshed with the second driven gear 7653 on one side. The second driven gear 7653 is located on the upper side of the second rack 766 and meshes with the second rack 766.

[0076] When the second saw blade plate 752 moves to a position abutting against the adjacent saw blade under the drive of the first saw blade plate 751, the drive rod 7521 connected to the second saw blade plate 752 is inserted into the adjacent second drive gear 7651. During the rotation of the second saw blade plate 752, the second saw blade plate 752 drives the connected second drive gear 7651 to rotate, and the second drive gear 7651 drives the second intermediate wheel 7652 to rotate. The second intermediate wheel 7652 drives the second driven gear 7653 to rotate, and the second driven gear 7653 drives the second rack 766 to move. The second rack 766, in turn, drives the third saw blade plate 753 to move and abut against the adjacent saw blade.

[0077] A recovery motor 78 is connected to one side of the first segment plate 751 to drive the rotation of the first segment plate 751, and the first segment plate 751 can rotate independently of the connected recovery motor 78. A reset member 79 is also connected between the first segment plate 751 and the third segment plate 753. As the end of the first segment plate 751 away from the first drive gear 7631 rotates towards the feeding tray 61, the first segment plate 751 drives the third segment plate 753 to move into the segment support plate 72 through the reset member 79.

[0078] By activating the recovery motor 78, the first segment plate 751 is rotated, thereby enabling the first segment plate 751, the second segment plate 752, and the third segment plate 753 to return to their initial positions, and allowing the first segment plate 751 to abut against the adjacent saw blade.

[0079] The reset component 79 includes a reset ratchet 791 fixedly connected to the rotation axis of the first segment plate 751, and the reset ratchet 791 can rotate under the drive of the first segment plate 751. A reset belt ring 792 is sleeved on the outside of the reset ratchet 791. When the end of the first segment plate 751 away from the connected first drive gear 7631 rotates towards the feed tray 61, the reset ratchet 791 engages with the externally sleeved reset belt ring 792. A reset belt 793 is sleeved on the outside of the reset belt ring 792, and a reset pulley 794 is sleeved on the side of the reset belt 793 away from the reset belt ring 792. A driven ratchet 795 is sleeved inside the reset pulley 794, and the driven ratchet 795 is fixedly connected to the adjacent second driven gear 7653. When the second driven gear 7653 drives the second rack 766 and the connected third split plate 753 to move towards the adjacent saw blade, the driven ratchet 795 does not engage with the external reset pulley 794.

[0080] During the reset process, the reset motor 78 is activated, which drives the first segment plate 751 to rotate. During the rotation of the first segment plate 751, the first drive gear 7631 rotates, the first drive gear 7631 rotates, the first intermediate gear 7632 rotates, the first intermediate gear 7632 rotates, the first driven gear 7633 rotates, and the first driven gear 7633 rotates, causing the first rack 764 and the second segment plate 752 to move into the segment support plate 72.

[0081] During rotation, the first segment plate 751 drives the reset ratchet 791 to rotate. At this time, the reset ratchet 791 engages with the reset belt ring 792, causing the reset ratchet 791 to rotate and the reset belt ring 792 to rotate. The reset belt ring 792 then drives the reset belt 793 to rotate. The reset belt 793, in turn, drives the reset pulley 794 to rotate, which in turn drives the driven ratchet 795 to rotate. The driven ratchet 795, in turn, drives the second rack 766 and the third segment plate 753 to move inward toward the segment support plate 72, thereby restoring the initial positions of the first segment plate 751, the second segment plate 752, and the third segment plate 753.

[0082] The implementation principle of Example 3 is as follows: During the process of picking up the saw blade, the saw blade drives the first segment plate 751 to move, and during the movement of the first segment plate 751, the second segment plate 752 is driven to abut against the remaining saw blade. Then, during the process of picking up the saw blade again, the second segment plate 752 drives the third segment plate 753 to abut against the remaining saw blade, thereby limiting the number of saw blades picked up by the electromagnetic block 54.

[0083] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
