Description

Technical Field

[0001] This application relates to the field of automated material handling, and in particular to a material handling machine. Background Technology

[0002] In the production of workpieces, automated production lines are typically used. Finished workpieces are mounted on fixtures, and a conveyor belt moves several fixtures to move the workpieces. The conveyor belt is embedded in an operating table. When the workpiece is transferred by the conveyor belt to the unloading station, a picking device mounted on the operating table removes the workpiece from the fixture and collects it. In existing technology, the picking machine is mounted on a frame, which is bolted to the operating table, suspending the picking machine above the conveyor belt.

[0003] When installing the material handling machine, holes need to be drilled in the control panel to connect the frame to the control panel using bolts. When the workpieces to be produced on the production line change, the material handling component and frame need to be removed and replaced with a material handling component and a new frame compatible with the new workpiece. If the new frame is different in size from the old frame, holes need to be drilled again in the control panel to install the new frame. Changing different material handling components requires multiple drillings in the control panel, which reduces the stability of the control panel structure and therefore needs improvement. Utility Model Content

[0004] In order to reduce the impact of material handling component replacement on the structural stability of the operating table, this application provides a material handling machine.

[0005] The material handling machine provided in this application adopts the following technical solution:

[0006] A material handling machine includes a work frame with a plurality of casters mounted on its bottom end; a clamping assembly is mounted on the work frame for fixing it to an operating table; a cantilever is mounted on the top end of the work frame, an adjustment assembly is mounted on the cantilever, an installation assembly is mounted on the adjustment assembly, and a material handling component is detachably mounted on the installation assembly; the adjustment assembly is used to adjust the height of the installation assembly, thereby adjusting the height of the material handling component; a counterweight is mounted on the side of the work frame away from the cantilever, so that the center of gravity of the work frame is located between the casters.

[0007] By adopting the above technical solution, when material needs to be picked up, the operator installs and secures the picking component onto the mounting component. The operator pushes the work frame against the operating table, and the clamping component clamps it from above and below the top and bottom walls of the operating table, achieving rapid fixation of the work frame to the operating table. The operator adjusts the height of the mounting component by adjusting the mounting component to adjust the height of the picking component relative to the workpiece on the operating table; by releasing the control of the mounting component on the picking component, the operator adjusts the position of the picking component on the mounting component, aligning the picking component with the workpiece, achieving rapid adjustment of the picking component. The picking component continuously picks up workpieces arriving at the unloading station and transfers them to a material bin placed on the counterweight platform. When the workpieces produced on this production line change, the operator quickly replaces different picking components using the mounting component, improving the speed of picking component changeover.

[0008] Optionally, the clamping assembly includes two clamping members, both mounted on the work frame and facing opposite directions, clamping the operating table from above and below; each clamping member includes a first adjusting plate, a first self-locking screw, and two fixed grippers; a guide rod is vertically mounted on the work frame, the first adjusting plate is sleeved on the guide rod, and the first adjusting plate can reciprocate along the length direction of the guide rod; the two fixed grippers are respectively mounted on both sides of the length direction of the first adjusting plate; the first self-locking screw is vertically arranged, and its two ends are rotatably connected to two crossbars respectively; a first nut is passed through the first adjusting plate, the first nut is fixedly connected to the first adjusting plate, and the first nut is threadedly engaged with the first self-locking screw; the end of the first self-locking screw near the operating table passes through the crossbar and is equipped with a knob.

[0009] By adopting the above technical solution, the operator turns two knobs to rotate two first self-locking screws. Since the first self-locking screws cannot move vertically, they force the two first nuts to move closer together, causing the two first adjusting plates to move closer together, and then the fixing claws on the two first adjusting plates to move closer together, until the upper and lower fixing claws abut against the top and bottom walls of the operating table, respectively, thus fixing the work frame to the operating table. This achieves rapid fixing of the work frame to the operating table, improving the efficiency of material handling and installation.

[0010] Optionally, the material handling assembly includes a mounting plate and a material handling component. The mounting plate is detachably connected to the mounting assembly, and the material handling component is mounted on the bottom wall of the mounting plate near the operating table. The material handling component is used to remove the workpiece located at the unloading station.

[0011] Optionally, the mounting assembly includes a mounting block, a pressure block, and a clamping bolt. The top wall of the mounting block is connected to an adjustment assembly. A slot is formed on the side wall of the mounting block near the mounting plate, and the edge of the mounting plate is inserted into the slot. A blind hole is formed on the top wall of the mounting block, and the blind hole communicates with the slot. The pressure block is inserted into the blind hole. A tooling plate is fixedly mounted on the top wall of the mounting block at the blind hole. The clamping bolt is threadedly connected to the tooling plate, and one end of the clamping bolt passing through the tooling plate can abut against the top wall of the pressure block to press the pressure block onto the mounting plate.

[0012] Optionally, a guide post is provided in the blind hole, one end of which is connected to the bottom wall of the mounting block located in the blind hole, and the other end is connected to the bottom wall of the tooling plate. The pressure block is sleeved on the guide post. A spring is sleeved on the guide post, one end of which is connected to the bottom wall of the mounting block located in the blind hole, and the other end is connected to the bottom wall of the pressure block.

[0013] Optionally, the mounting plate has a groove on its top wall, and the bottom wall of the pressure block protrudes outward, so that the pressure block can be inserted into the groove and is in contact with the inner wall of the groove.

[0014] By adopting the above technical solution, when the material receiving component needs to be installed, the pressure block is lifted by the spring. The operator holds the mounting plate and inserts it into the two mounting blocks through the two slots. The operator tightens the clamping bolts to lower the pressure block, compressing the spring. This continues until the bottom wall of the pressure block abuts against the inner wall of the groove, making it difficult for the mounting plate to move horizontally. The mounting plate is then installed, achieving rapid material receiving. When fine-tuning the position of the mounting plate is required, the operator loosens the clamping bolts but does not remove them, lifting the pressure block. The operator then drives the mounting plate to slide along the length of the slot. After fine-tuning, the clamping bolts are tightened to secure it. When replacing the material receiving component, the mounting plate connected to the old component is removed from the mounting block, and the mounting plate connected to the new component is fixed to the mounting block. This detachable connection between the mounting plate and the mounting block enables rapid replacement of the material receiving component.

[0015] Optionally, the adjustment assembly includes a second adjustment plate, a second self-locking screw, a linear bearing, and a shaft. The shaft is slidably engaged with the cantilever via the linear bearing. One end of the shaft is connected to the top wall of the mounting block, and the other end is connected to the second adjustment plate via a plate. A second nut is threaded onto the second adjustment plate, and the second nut is threadedly engaged with the second self-locking screw. One end of the second self-locking screw is rotatably connected to a plate on the cantilever, and the other end of the second self-locking screw passes through the second nut and is mounted on a turntable. The turntable is fixedly connected to the second self-locking screw and rotates synchronously. A handle is eccentrically mounted on the turntable for gripping.

[0016] By adopting the above technical solution, when the height of the material being picked up needs to be adjusted, the operator holds the handle to rotate the turntable, which in turn rotates the second self-locking screw. Since the second self-locking screw cannot move vertically, its rotation forces the second nut to descend. The second nut then lowers the second adjusting plate, which in turn lowers the two mounting blocks via four shafts. This allows for rapid adjustment of the material's height by adjusting the height of the mounting blocks, thus improving the efficiency of material adjustment.

[0017] Optionally, the work frame is also equipped with a feeding trough, which is installed on the side of the work frame away from the material picking component. The feeding trough is set lower than the material picking component in the height direction and is located above the counterweight platform. The feeding trough is inclined downward from the work frame in the direction away from the material picking component.

[0018] By adopting the above technical solution, the pick-up component removes the workpiece from the operating table and, under the action of inertia, transfers the workpiece to the end of the feeding trough near the pick-up component. Under the action of gravity, the workpiece slides along the feeding trough away from the pick-up component and is collected by the operator, realizing automated feeding and improving the efficiency of picking up materials.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. When material needs to be picked up, the operator installs and secures the picking component onto the mounting assembly. The operator pushes the work frame against the worktable, clamping it from above and below against the top and bottom walls of the worktable using the clamping assembly, thus quickly fixing the work frame to the worktable. The operator adjusts the height of the mounting assembly by adjusting the mounting assembly to adjust the height of the picking component relative to the workpiece on the worktable; by releasing the control of the mounting assembly on the picking component, the operator adjusts the position of the picking component on the mounting assembly, aligning it with the workpiece, thus achieving rapid adjustment of the picking component. The picking component continuously picks up workpieces arriving at the unloading station and transfers them to a hopper placed on the counterweight platform. When the workpieces produced on this production line change, the operator quickly replaces different picking components using the mounting assembly, improving the speed of picking component changeover.

[0021] 2. When installing the material picker, the pressure block is lifted by the spring. The operator holds the mounting plate and inserts it into the two mounting blocks through the two slots. The operator tightens the clamping bolts to lower the pressure block, compressing the springs. This continues until the bottom wall of the pressure block abuts against the inner wall of the groove, making it difficult for the mounting plate to move horizontally. The mounting plate is then installed, enabling rapid material picker installation. When fine-tuning the mounting plate's position is required, the operator loosens the clamping bolts but does not remove them, slightly lifting the pressure block. The operator then drives the mounting plate to slide along the length of the slot. After fine-tuning, the clamping bolts are tightened to secure it. When replacing the material picker, the mounting plate connected to the old material picker is removed from the mounting block, and the mounting plate connected to the new material picker is fixed to the mounting block. This detachable connection between the mounting plate and the mounting block allows for rapid material picker replacement.

[0022] 3. When the height of the material being picked up needs to be adjusted, the operator holds the handle to rotate the turntable, which in turn rotates the second self-locking screw. Since the second self-locking screw cannot move vertically, its rotation forces the second nut to descend. The second nut then lowers the second adjusting plate, which in turn lowers the two mounting blocks via four shafts. By adjusting the height of the mounting blocks, the height of the material being picked up can be quickly adjusted, improving the efficiency of the adjustment process. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a material handling machine. (Refer to...) Figure 1 A material handling machine includes a work frame 1, which comprises four horizontal bars 11 at the bottom and vertical bars 12 eccentrically mounted on the horizontal bars 11. The horizontal bars 11 are fixed to each other by welding, and the vertical bars 12 are also fixed to the horizontal bars 11 by welding. Casters 2 are bolted to the four corners of the rectangle formed by the four horizontal bars 11, with the outer perimeter of the casters 2 abutting the ground. A cantilever 13 is mounted on the top of the vertical bar 12 away from the casters 2, and the cantilever 13 is mounted on the side of the work frame 1 near the operating table 8. An adjustment assembly 4 is mounted on the cantilever 13, and a mounting assembly 5 is mounted on the end of the adjustment assembly 4 away from the cantilever 13. The mounting assembly 5 is used to mount a material handling assembly 6. The adjustment assembly 4 can adjust the height of the mounting assembly 5, thereby adjusting the height of the material handling assembly 6 relative to the operating table 8.

[0030] To balance the center of gravity of the workbench 1, a counterweight platform 7 is also provided on the workbench 1. The counterweight platform 7 is welded to the vertical rod 12. Two support rods are welded to the bottom wall of the workbench near the horizontal rod 11, with the ends of the rods away from the counterweight platform 7 welded to the horizontal rod 11. A material bucket 71 for receiving workpieces is placed on the counterweight platform 7. A material discharge trough 9 is also installed on the workbench 1. One end of the material discharge trough 9 is bolted to the horizontal plate between the two vertical rods 12 of the workbench 1, and the other end is inclined towards the material bucket 71. The material discharge trough 9 is inclined downwards away from the workbench 1. The material discharge trough 9 is positioned below the material receiving assembly 6 in the height direction and above the counterweight platform 7.

[0031] The work frame 1 is also equipped with a clamping assembly 3, which is installed on the side of the vertical rod 12 near the operating table 8. The clamping assembly 3 includes two clamping parts 31, which are arranged in opposite directions and are both installed on the work frame 1. The two clamping parts 31 clamp the top wall and bottom wall of the operating table 8 from above and below, respectively, to fix the work frame 1 on the operating table 8.

[0032] When material needs to be picked up, the operator installs and secures the material picking component 6, which is compatible with the production line, onto the mounting component 5. At this time, the work frame 1 is moved away from the operating table 8. The operator pushes the work frame 1 closer to the operating table 8 until the vertical rod 12, away from the side wall of the counterweight 7, is against the side wall of the operating table 8, and the material picking component 6 is positioned above the operating table 8. The operator controls the upper clamping member 31 to press against the top wall of the operating table 8 from above, and controls the lower clamping member 31 to press against the bottom wall of the operating table 8 from below, thus fixing the work frame 1 to the operating table 8. The operator adjusts the height of the mounting component 5 by adjusting the adjusting component 4 to adjust the height of the material picking component 6 relative to the workpiece on the operating table 8. If the material picking component 6 is not aligned with the workpiece along the length of the unloading trough 9, the operator can loosen the control of the mounting component 5 on the material picking component 6 and adjust its position on the mounting component 5 to align it with the workpiece before re-fixing it to the mounting component 5. Start the material handling component 6. The material handling component 6 continuously picks up the workpiece that has arrived at the unloading station and transfers it to the end of the unloading trough 9 away from the material bucket 71. The workpiece slides into the material bucket 71 along the inclined inner wall of the unloading trough 9.

[0033] After the workpiece is picked up from the production line, the operator releases the two clamping parts 31 from the operating table 8 and pushes the work frame 1 away from the operating table 8. Repeating the above steps, the operator can quickly replace different picking components 6 by installing component 5, and then adjust the height of the picking component 6 relative to the workpiece on the operating table 8 by adjusting component 4.

[0034] Reference Figure 1 and Figure 2Taking the clamping component 31 below the counterweight platform 7 as an example, two horizontal plates are installed on the work frame 1, and a guide rod 14 is installed vertically between the two horizontal bars 11. In order to balance, each clamping component 31 in this embodiment is provided with two guide rods 14. A first adjusting plate 311 is sleeved on the two guide rods 14. A fixed claw 313 is installed on both sides of the top wall of the first adjusting plate 311 along its length direction by bolts. The top wall of the fixed claw 313 can abut against the bottom wall of the operating table 8. A first nut 314 is inserted through the first adjusting plate 311, and the first nut 314 is connected to the first adjusting plate 311 by bolts. A first self-locking screw 312 is inserted inside the first nut 314. In this embodiment, the first self-locking screw 312 is a trapezoidal screw, and the first nut 314 is threadedly connected to the first self-locking screw 312. The first self-locking screw 312 is vertically arranged. The bottom end of the first self-locking screw 312 is rotatably connected to the horizontal plate located below through a rotating shaft. The top end of the first self-locking screw 312 passes through the first nut 314 and is rotatably connected to the horizontal plate located above through a rotating shaft. A knob 315 is installed on the top end of the first self-locking screw 312 passing through the horizontal plate. The knob 315 rotates synchronously with the first self-locking screw 312.

[0035] When the vertical rod 12 is against the side wall of the operating table 8, the horizontal plate of the fixed clamp 313 is located below the bottom wall of the operating table 8. The operator turns the knob 315 clockwise, which drives the first self-locking screw 312 to rotate clockwise. Since the first self-locking screw 312 cannot move vertically, its clockwise rotation forces the first nut 314 to rise vertically. The first nut 314 drives the first adjusting plate 311 to rise along the length of the guide rod 14. The first adjusting plate 311 drives both fixed clamps 313 to rise simultaneously until the top wall of the fixed clamp 313 abuts against the bottom wall of the operating table 8. Before the clamping member 31 below clamps, the operator first operates the clamping member 31 located above the counterweight 7 to clamp the operating table 8 from above. The two clamping members 31 together clamp the operating table 8, fixing the work frame 1 to the operating table 8. When it is necessary to move the work rack 1, the operator turns the two knobs 315 to make the fixed jaws 313 on the two clamping parts 31 move away from each other, release the clamp on the operating table 8, and the operator can push the work rack 1 away.

[0036] Reference Figure 3The adjustment assembly 4 includes a second adjustment plate 41 movably disposed above the cantilever 13. Two shafts 44 are mounted on each end of the second adjustment plate 41 along its length. The two shafts 44 located on the same side of the length direction of the second adjustment plate 41 are located on opposite sides of its width direction. The shafts 44 are slidably engaged with the cantilever 13 via linear bearings 43. A second nut 45 passes through the middle of the second adjustment plate 41 and is fixedly connected to the second adjustment plate 41 by bolts. A second self-locking screw 42 passes through the second nut 45. In this embodiment, the second self-locking screw 42 is also a trapezoidal screw, and the second nut 45 and the second self-locking screw 42 are threadedly engaged. One end of the second self-locking screw 42 is rotatably connected to a plate mounted on the cantilever 13 via a rotating shaft, and the other end passes through the second nut 45 and is mounted on a turntable 46. The turntable 46 is fixedly connected to the second self-locking screw 42 by bolts and rotates synchronously. A handle 47 is eccentrically mounted on the top wall of the turntable 46 away from the second adjustment plate 41 for gripping. The end of the shaft 44 away from the second adjusting plate 41 is connected to the mounting assembly 5.

[0037] Reference Figure 3 and Figure 4 The mounting assembly 5 includes a mounting block 51, the top wall of which is fixedly connected to the shaft 44 by a clamp. The two ends of the second adjusting plate 41 along its length are respectively connected to a mounting block 51 via shafts. The material handling assembly includes a mounting plate 61 and a material handling component 62 mounted on the bottom wall of the mounting plate 61 near the operating table. The material handling component 62 is a standard component adapted to different workpieces. The mounting plate 61 is secured between two mounting blocks 51.

[0038] Two mounting blocks 51 have slots 511 on their adjacent sidewalls, with the length of the slots 511 parallel to the length of the mounting blocks 51. The two ends of the mounting plate 61 are inserted into the slots 511 on both sides. A blind hole 512 is formed on the top wall of the mounting block 51, communicating with the slots 511 at its center. A pressure block 52 is slidably disposed within the blind hole 512. A tooling plate 56 is bolted to the top wall of the mounting block 51 at the blind hole 512. A screw hole is formed on the tooling plate 56, into which a clamping bolt 53 is inserted. The clamping bolt 53 passes through the bottom end of the tooling plate 56 and abuts against the top wall of the pressure block 52. A guide post 54 is disposed within the blind hole 512, with one end engaging with the bottom wall of the blind hole 512 and the other end engaging with the bottom wall of the tooling plate 56. A pressure block 52 is fitted onto a guide post 54, and a spring 55 is fitted onto the guide post 54. One end of the spring 55 is glued to the bottom wall of the blind hole 512, and the other end is glued to the bottom wall of the pressure block 52. The bottom end of the pressure block 52, away from the clamping bolt 53, can enter the slot 511 through the blind hole 512. A groove 611 is formed at the edge of the top wall of the mounting plate 61, and the length direction of the groove 611 is parallel to the length direction of the mounting block 51. The pressure block 52 can be inserted into the groove 611, and the bottom wall of the pressure block 52 protrudes outward and is in contact with the inner wall of the groove 611.

[0039] When the material handling assembly 6 needs to be installed, the pressure block 52 is lifted by the spring 55, and the bottom wall of the pressure block 52 does not protrude from the blind hole 512. The operator holds the mounting plate 61 and inserts it into the two mounting blocks 51 from the same end of the two slots 511. The operator tightens the clamping bolt 53, causing it to descend relative to the tooling plate 56 until the bottom wall of the clamping bolt 53 abuts against the top wall of the pressure block 52. The pressure block 52 then descends along the length of the guide post 54, and the bottom wall of the pressure block 52 protrudes from the blind hole 512 and enters the slot 511. At this time, the spring 55 is compressed. The clamping bolt 53 drives the pressure block 52 to continue descending until the bottom wall of the pressure block 52 abuts against the top wall of the mounting plate 61 located in the groove 611. The mounting plate 61 is difficult to move horizontally, and the installation of the mounting plate 61 is complete. When the position of the mounting plate 61 needs to be fine-tuned, the operator loosens the clamping bolt 53 but does not remove it. The spring 55 lifts the pressure block 52, and the operator drives the mounting plate 61 to slide along the length of the slot 511. After the fine-tuning is completed, the clamping bolt 53 is tightened to complete the fixation.

[0040] When the height of the picking component 62 needs to be adjusted, the operator holds the handle 47 and causes the handle 47 to drive the turntable 46 to rotate clockwise around the axis of the second self-locking screw 42. The turntable 46 drives the second self-locking screw 42 to rotate clockwise. Since the second self-locking screw 42 cannot move in the vertical direction, the second self-locking screw 42 forces the second nut 45 to descend. The second nut 45 drives the second adjusting plate 41 to descend. The second adjusting plate 41 drives the two mounting blocks 51 to descend in the vertical direction through the four shafts 44. The mounting blocks 51 drive the mounting plate 61 to descend, bringing the picking component 62 closer to the workpiece. The position adjustment of the picking component 62 is completed.

[0041] Reference Figure 3 In this embodiment, the workpiece to be picked up is a ring-shaped workpiece. The picking component 62 includes a stop block 621, which is suspended on the bottom wall of the mounting plate 61 near the operating table 8 by bolts. The stop block 621 protrudes from the middle of its height towards the side near the unloading trough 9. A driving component 622 is provided on the side of the stop block 621 near the unloading trough 9. In this embodiment, the driving component 622 is a cylinder. The fixed end of the driving component 622 is mounted on the bottom wall of the mounting plate 61 by bolts. A plate is mounted on the movable end of the driving component 622. A rotating plate 623 is rotatably mounted on the plate via a rotating shaft. A pneumatic gripper 624 is bolted to the bottom wall of the rotating plate 623 away from the driving component 622. The two grippers of the pneumatic gripper 624 have their sidewalls facing away from each other and can abut against the inner peripheral wall of the ring-shaped workpiece.

[0042] After the position of the material handling component 62 is adjusted, the pneumatic gripper 624 is positioned directly above the unloading station. The drive unit 622 is activated, causing the rotating plate 623 to descend away from the protrusion of the stop block 621. The rotating plate 623 then lowers the pneumatic gripper 624. At this time, the conveyor belt on the operating table 8 transfers a workpiece to the unloading station. The two grippers of the pneumatic gripper 624 reach the center of the annular workpiece. The pneumatic gripper 624 is then activated, moving its two grippers away from each other and bracing against the inner wall of the workpiece. The drive unit 622 then drives the rotating plate 623 to rise towards the protrusion of the stop block 621. The rotating plate 623 then raises the pneumatic gripper 624, which, through friction, lifts the workpiece and disengages it from the fixture on the operating table 8. The driving component 622 drives the rotating plate 623 to continue rising. The end of the rotating plate 623 near the stop block 621 contacts the stop block 621 and rotates until the top wall of the rotating plate 623 is in contact with the inclined side wall of the stop block 621, at which point the moving end of the driving component 622 stops rising. At this time, the pneumatic gripper 624, holding the workpiece, rotates and tilts downwards from the stop block 621 towards the feed trough 9. Simultaneously, the two grippers of the pneumatic gripper 624 move closer together to release control of the workpiece. Under the action of inertia, the workpiece detaches from the pneumatic gripper 624 and falls onto the feed trough 9, sliding along the feed trough 9 under the action of gravity. At this time, the moving end of the driving component 622 descends, and the rotating plate 623 rotates until the side wall of the rotating plate 623 away from the feed trough 9 is in contact with the vertical side wall of the stop block 621. The rotating plate 623 drives the pneumatic gripper 624 to rotate until the pneumatic gripper 624 is in a vertical position. The drive unit 622 drives the rotating plate 623 to drive the pneumatic gripper 624 to descend vertically to grab the annular workpiece that has arrived at the unloading station.

[0043] If the workpiece produced by the production line changes, the operator releases the clamping block 52 from the outside of the mounting plate 61 to remove the material take-up part 62, replaces it with a new material take-up part 62 that is still installed on the mounting plate 61, and installs the new mounting plate 61 on the mounting block 51 to adapt to the new workpiece.

[0044] The implementation principle of a material handling machine according to an embodiment of this application is as follows: Different material handling components 62 are set up to adapt to different workpieces, and each material handling component 62 is mounted on a mounting plate 61. The operator inserts the mounting plate 61 into the slot 511 and tightens the clamping bolt 53 to make the bottom wall of the pressure block 52 adhere to the inner wall of the groove 611, thus fixing the mounting plate 61 and the material handling component 62 to the mounting block 51. The operator pushes the work frame 1 until it rests against the operating table 8, and turns the knob 315 to bring the fixing jaws 313 on the two clamping components 31 closer together, clamping the operating table 8 from above and below to fix the work frame 1 to the operating table 8. At this time, the clamping bolt 53 can be loosened to adjust the position of the material handling component 62 along the length direction of the mounting block 51. The operator holds the handle 47 and rotates it to drive the second adjusting plate 41 to adjust the height of the mounting block 51 via the shaft 44, thereby achieving height adjustment of the material handling component 62. When it is necessary to replace the material receiving component 62, the material receiving component 62 can be quickly replaced by disassembling and connecting the mounting block 51 and the mounting plate 61.

[0045] 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.
