[0011] In some embodiments, the lifting drive assembly further includes a transmission unit comprising a worm gear and a worm, the worm gear being mounted on the rotating shaft and the worm being mounted on the drive end of the rotating drive member and meshing with the worm gear.
[0012] In some embodiments, the mounting base has a guide channel that extends through the top and bottom of the mounting base;
[0013] The lifting seat is disposed through the guide channel and is slidably connected to the mounting seat. One end of the lifting seat protruding from the bottom of the mounting seat is used to install the loading shaft.

[0031] This application provides a lifting mechanism for driving the loading shaft to rise or fall, so as to adjust the position of the loading shaft in the vertical direction, so as to facilitate loading the material roll onto the loading shaft or unloading the material roll on the loading shaft.
[0032] Please see Figures 1 to 2 The lifting mechanism includes a mounting base 10, a lifting seat 20, and a lifting drive assembly (not shown). The lifting seat 20 is vertically connected to the mounting base 10. A loading shaft is mounted on the lifting seat 20, so that the lifting seat 20 can drive the loading shaft to rise and fall relative to the mounting base 10. The lifting drive assembly includes a sprocket (not shown), a rotary drive component 31, and a ring chain 33. The sprocket is rotatably connected to the mounting base 10. The rotary drive component 31 is mounted on the mounting base 10 and is connected to the sprocket, so that the rotary drive component 31 can drive the sprocket to rotate relative to the mounting base 10. The ring chain 33 is wound around the sprocket, so that the rotation of the sprocket can drive the ring chain 33 to rise and fall. One end of the ring chain 33 is connected to the lifting seat 20, so that the rising and falling of the ring chain 33 can drive the lifting seat 20 to rise and fall.
[0033] In actual use, the aforementioned lifting mechanism utilizes the rotary drive component 31 to drive the sprocket to rotate. The sprocket drives the ring chain 33 to rise or fall, which in turn drives the lifting seat 20 to rise or fall relative to the mounting seat 10. The lifting seat 20 then drives the loading shaft to rise or fall, thus achieving vertical position adjustment of the loading shaft. After the loading shaft is properly positioned vertically, the material roll is loaded onto the loading shaft or unloaded from the loading shaft.
[0034] Thus, the loading shaft is installed on the lifting seat 20, and the lifting seat 20 and the loading shaft are supported by the ring chain 33. The lifting seat 20 and the loading shaft are lifted and lowered by the rotation of the sprocket. The sprocket and the ring chain 33 have strong load-bearing capacity, and the transmission structure of the sprocket and the ring chain 33 is compact and low in cost. This is beneficial to improving the load-bearing capacity of the lifting mechanism, reducing the space required by the lifting mechanism, and reducing the cost of the lifting mechanism.
[0035] Understandably, the ring chain 33 is a chain composed of multiple nested metal rings, characterized by high strength and good wear resistance, capable of withstanding significant tensile and impact forces, thus improving the load-bearing capacity of the lifting mechanism. The sprocket is a wheel with interlocking chain teeth, used to mesh with the metal rings of the ring chain 33, thereby enabling the ring chain 33 to rise or fall when the sprocket rotates.
[0036] In a specific embodiment, the lifting drive assembly further includes a chain box 40 mounted on the mounting base 10. A ring chain 33 is wound around a sprocket, with both ends of the ring chain 33 extending downwards. One end of the ring chain 33 is connected to the lifting seat 20, and the other end is connected to the chain box 40. The chain box 40 is used to store the ring chain 33. Thus, when the sprocket rotates and drives the lifting seat 20 to rise via the ring chain 33, the portion of the ring chain 33 between the sprocket and the lifting seat 20 shortens, while the portion of the ring chain 33 between the sprocket and the chain box 40 lengthens, and the lengthened portion of the ring chain 33 is stored in the chain box 40. When the sprocket rotates and drives the lifting seat 20 to fall via the ring chain 33, the portion of the ring chain 33 between the sprocket and the lifting seat 20 lengthens, while the portion of the ring chain 33 between the sprocket and the chain box 40 shortens.
[0037] Furthermore, at least two sprockets, at least two ring chains 33, and at least two chain boxes 40 are provided. Each sprocket is rotatably connected to the mounting base 10, and each ring chain 33 is wound around the corresponding sprocket, with both ends of each ring chain 33 extending downwards. One end of each ring chain 33 is connected to the lifting seat 20, and the other end of each ring chain 33 is connected to a corresponding chain box 40. Each chain box 40 is used to store a corresponding ring chain 33. In this way, at least two ring chains 33 jointly support the lifting seat 20 and jointly drive the lifting seat 20 to rise or fall, further improving the load-bearing capacity of the lifting mechanism.
[0038] Furthermore, the lifting drive assembly also includes a rotating shaft 35, which is rotatably connected to the mounting base 10. This rotating shaft 35 is drively connected to a rotating drive member 31, enabling the rotating drive member 31 to drive the rotating shaft 35 to rotate relative to the mounting base 10 about its own axis. Each sprocket is mounted on the rotating shaft 35, allowing the rotating shaft 35 to drive each sprocket to rotate, thereby causing each sprocket to raise or lower the lifting seat 20 via its respective ring chain 33.
[0039] In a specific embodiment, the lifting drive assembly further includes a transmission unit (not shown), which includes a worm and a worm wheel. The worm is mounted on the drive end of the rotary drive component 31, enabling the rotary drive component 31 to drive the worm to rotate. The worm wheel is mounted on the rotary shaft 35, enabling the worm wheel to drive the rotary shaft 35 to rotate. The worm and the worm wheel mesh with each other. Thus, when the rotary drive component 31 drives the worm to rotate, the worm then drives the worm wheel to rotate, the worm wheel then drives the rotary shaft 35 to rotate, the rotary shaft 35 then drives each sprocket to rotate, and each sprocket then drives the lifting seat 20 to rise or fall via its corresponding ring chain 33, and the lifting seat 20 then drives the loading shaft to rise or fall. Optionally, the rotary drive component 31 can be a motor.
[0040] It should be noted that the transmission unit uses worm gears and worm shafts for transmission. Worm gear and worm shaft transmissions are characterized by smooth transmission and high load-bearing capacity, which helps to further improve the load-bearing capacity of the lifting mechanism. Worm gear and worm shaft transmissions also have a self-locking function, which can prevent the lifting seat 20, the loading shaft, and the material roll on the loading shaft from falling.
[0041] In other embodiments, the transmission unit may also adopt other types of transmission structures, such as gear transmission structures, as long as it can transmit the rotational motion output by the rotary drive 31 to the rotary shaft 35, and is not limited here.
[0042] In some embodiments, the lifting mechanism further includes a connecting assembly 50, which includes a connecting seat 51, a hinge shaft 52, and a hinge base 53. Two ring chains 33 are provided, one end of which is connected to one end of the connecting seat 51, and the other end of which is connected to the other end of the connecting seat 51. The connecting seat 51 has a hinge hole located between its two ends, that is, approximately in the middle of the connecting seat 51. The hinge shaft 52 passes through the hinge hole in the connecting seat 51, and the hinge base 53 is hinged to the connecting seat 51 via the hinge shaft 52, and is connected to the lifting seat 20. Thus, when the two ring chains 33 jointly drive the connecting seat 51 to rise or fall, the connecting seat 51 drives the hinge base 53 to rise or fall via the hinge shaft 52, and the hinge base 53 then drives the lifting seat 20 to rise or fall.
[0043] Please see Figures 3 to 5 In the embodiments of this application, the mounting base 10 has a guide channel that extends through the top and bottom of the mounting base 10. The lifting seat 20 passes through the guide channel of the mounting base 10 and is slidably connected to the mounting base 10, meaning that the lifting seat 20 can move up and down along the guide channel of the mounting base 10. One end of the lifting seat 20 protruding from the bottom of the mounting base 10 is used to install the loading shaft. Thus, by fitting the lifting seat 20 within the guide channel of the mounting base 10, it serves two purposes: firstly, it guides the lifting seat 20, making its lifting movement smoother; secondly, it saves space, making the structure more compact and further reducing the space required for the lifting mechanism.
[0044] Optionally, the lifting seat 20 is provided with a slide rail 21, and the inner wall of the mounting base 10 is provided with a slider 110. The slider 110 slides with the slide rail 21, thereby guiding the lifting of the lifting seat 20 by sliding the slider 110 along the slide rail 21.
[0045] In a specific embodiment, the lifting mechanism further includes a first limiting block 61 and a first stop block 63. The first limiting block 61 is fixedly connected to the lifting seat 20, and the first stop block 63 is fixedly connected to the mounting seat 10. When the lifting seat 20 rises relative to the mounting seat 10, it can cause the first limiting block 61 to engage with the first stop block 63, thereby preventing the lifting seat 20 from continuing to rise relative to the mounting seat 10, that is, limiting the lifting seat 20 to the upper limit position.
[0046] In a specific embodiment, the lifting mechanism further includes a second limiting block 65 and a second stop block 67. The second limiting block 65 is fixedly connected to the lifting seat 20, and the second stop block 67 is fixedly connected to the mounting seat 10. When the lifting seat 20 descends relative to the mounting seat 10, it can cause the second limiting block 65 to engage with the second stop block 67, thereby preventing the lifting seat 20 from continuing to descend relative to the mounting seat 10, that is, limiting the lifting seat 20 to the lower limit position.
[0047] It should be noted that the lifting and lowering of the lifting seat 20 is limited between the upper limit position and the lower limit position by the first limit block 61 and the first stop block 63, as well as the second limit block 65 and the second stop block 67, so as to prevent the lifting seat 20 from detaching from the mounting seat 10 due to excessive stroke.
[0048] Optionally, the first limiting block 61 is installed at the bottom end of the lifting seat 20, and the first stop block 63 is installed at the bottom end of the mounting base 10. When the lifting seat 20 rises relative to the mounting base 10 to the upper limit position, the first limiting block 61 and the first stop block 63 engage to stop the lifting seat 20 from rising further. In other embodiments, the first limiting block 61 may also be installed at other parts of the lifting seat 20, and the first stop block 63 may also be installed at other parts of the mounting base 10, as long as it can limit the lifting seat 20 when it rises to the upper limit position.
[0049] Optionally, the second limiting block 65 is installed at the top of the lifting seat 20 and on the inner wall of the mounting base 10, located between the top and bottom ends of the mounting base 10. When the lifting seat 20 descends to its lower limit position relative to the mounting base 10, the second limiting block 65 engages with the second stop block 67 to prevent the lifting seat 20 from descending further. In other embodiments, the second limiting block 65 and the second stop block 67 can also be installed at other parts of the lifting seat 20 and the mounting base 10, as long as they can limit the descent of the lifting seat 20 to its lower limit position.
[0050] Optionally, the first stop block 63 is a first elastic block, that is, the first stop block 63 is elastic. In this way, it can buffer the impact force between the first limiting block 61 and the first stop block 63, and avoid hard impact between the first limiting block 61 and the first stop block 63.
[0051] Optionally, the second stop block 67 is a second elastic block, that is, the second stop block 67 is elastic. In this way, it can buffer the impact force between the second limit block 65 and the second stop block 67, and avoid hard impact between the second limit block 65 and the second stop block 67.
[0052] Based on the above-described lifting mechanism, this application also provides a handling device. The handling device includes a loading shaft and the lifting mechanism as described in any of the above embodiments. Further, the handling device also includes a rotating mechanism, with the mounting base 10 connected to the rotating mechanism, enabling the rotating mechanism to drive the mounting base 10 to rotate, thereby driving the loading shaft mounted on the lifting base 20 to rotate, thus adjusting the orientation of the loading shaft.
[0053] Furthermore, the handling equipment also includes a translation mechanism, and a rotating mechanism is installed on the translation mechanism, so that the translation mechanism can drive the rotating mechanism, the lifting mechanism and the loading shaft to move together in the horizontal direction to realize the transfer of the material roll on the loading shaft.
[0054] It should be noted that the rotating and translating mechanisms can adopt relatively mature existing technologies, as long as they can drive the loading shaft to rotate and translate, and no restrictions are imposed here.
[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
