[0002] In the battery production process, handling equipment is needed to move electrode rolls, thereby realizing the loading or transfer of electrode rolls, such as loading electrode rolls to winding equipment.

[0066] Please see Figure 1 and Figure 2 This application provides a handling device, including a loading device 100 and a motion drive device 200. The loading device 100 is used for loading or unloading material rolls. The loading device 100 is connected to the drive end of the motion drive device 200, enabling the motion drive device 200 to drive the loading device 100 to move, thereby realizing the transfer of the material rolls. Specifically, the motion drive device 200 can drive the loading device 100 to translate along a first horizontal direction X1 and a second horizontal direction X2.

[0067] Specifically, the motion drive device 200 includes a first guide rail 10, a second guide rail 20, and a connecting unit 50e (not shown in the figure). A connecting unit 50e is provided between the first guide rail 10 and the second guide rail 20. A connecting unit 50e is also provided between the second guide rail 20 and the loading device 100. The connecting unit 50e between the first guide rail 10 and the second guide rail 20, and the connecting unit 50e between the second guide rail 20 and the loading device 100, have the same structure; therefore, the following description uses the connecting unit 50e between the first guide rail 10 and the second guide rail 20 as an example.

[0068] The connecting unit 50e includes a movable base 51, a suspension mechanism 70, and a moving drive mechanism 50. The movable base 51 is movably connected to the first guide rail 10, and the suspension mechanism 70 is connected between the movable base 51 and the second guide rail 20, i.e., the second guide rail 20 is suspended from the movable base 51 by the suspension mechanism 70. The moving drive mechanism 50 is mounted on the movable base 51, enabling the moving drive mechanism 50 and the movable base 51 to move synchronously along the first guide rail 10. The moving drive mechanism 50 is configured to be controllably engaged or disengaged from the first guide rail 10. Thus, when the handling equipment switches to automatic drive mode, the moving drive mechanism 50 is controlled to engage with the first guide rail 10, allowing the moving drive mechanism 50 to drive the movable base 51 to move along the first guide rail 10, thereby driving the loading device 100 to move along the first horizontal direction X1. When the handling equipment switches to manual drive mode, the moving drive mechanism 50 is controlled to disengage from the first guide rail 10, preventing the moving drive mechanism 50 from driving the movable base 51 to move along the first guide rail 10. At this time, the loading device 100 can be manually pushed to move along the first guide rail 10 (i.e., the first horizontal direction X1).

[0069] It should be noted that the mobile drive mechanism 50 enables the handling equipment to switch between automatic drive mode and manual drive mode, thereby allowing the handling equipment to adapt to different working conditions, such as material roll transfer operations, maintenance or debugging, which helps to improve the compatibility of the handling equipment.

[0070] It is understandable that, since a connecting unit 50e is also provided between the second guide rail 20 and the loading device 100, when the handling equipment switches to automatic drive mode, the moving drive mechanism 50 controlling the second guide rail 20 and the loading device 100 engages with the second guide rail 20, enabling the moving seat 51 to move along the second guide rail 20, thereby driving the loading device 100 to move along the second horizontal direction X2. When the handling equipment switches to manual drive mode, the moving drive mechanism 50 controlling the second guide rail 20 and the loading device 100 disengages from the second guide rail 20, preventing the moving seat 51 from moving along the second guide rail 20. In this case, the loading device 100 can be manually pushed to move along the second guide rail 20 (i.e., the second horizontal direction X2).

[0071] In the embodiments of this application, the moving drive mechanism 50 includes a mounting frame 521, a friction wheel 523, and a rotating drive member 528. The mounting frame 521 is movably connected to the movable seat 51, and the friction wheel 523 is rotatably connected to the mounting frame 521. The rotating drive member 528 is mounted on the mounting frame 521 and is drivenly connected to the friction wheel 523, enabling the rotating drive member 528 to drive the friction wheel 523 to rotate. The mounting frame 521 can move controllably relative to the movable seat 51, thereby causing the friction wheel 523 to abut or separate from the first guide rail 10. It should be noted that the rotating drive member 528 can be a drive member that outputs rotational motion, such as a motor, as long as it can drive the friction wheel 523 to rotate; no limitation is made here.

[0072] Thus, when the handling equipment needs to switch to manual drive mode, the mounting frame 521 is controlled to move relative to the movable seat 51, causing the mounting frame 521 to drive the friction wheel 523 to separate from the first guide rail 10. At this time, the loading device 100 can be manually pushed to move along the first guide rail 10. When the handling equipment needs to switch to automatic drive mode, the mounting frame 521 is controlled to move relative to the movable seat 51, causing the mounting frame 521 to drive the friction wheel 523 to abut against the first guide rail 10. At this time, the friction wheel 523 can be automatically driven to rotate by rotating the drive component 528, thereby driving the movable seat 51 to move along the first guide rail 10 through the friction between the friction wheel 523 and the first guide rail 10, and thus driving the loading device 100 to move along the first horizontal direction X1.

[0073] In some embodiments, the moving drive mechanism 50 further includes a mounting shaft 525, which is fixedly connected to the movable seat 51. A mounting bracket 521 is rotatably connected to the mounting shaft 525, meaning that the mounting bracket 521 can rotate around the mounting shaft 525, thereby causing the friction wheel 523 to abut or separate from the first guide rail 10. Thus, the oscillating motion of the mounting bracket 521 around the mounting shaft 525 is used to drive the friction wheel 523 to abut or separate from the first guide rail 10. The operation is stable and reliable, and the structure is simple, requiring minimal space.

[0074] Furthermore, the mounting bracket 521 can be controlled to rotate around the mounting shaft 525 to a first position and a second position. When the mounting bracket 521 rotates to the first position, the friction wheel 523 separates from the first guide rail 10. At this time, the handling equipment switches to manual drive mode, that is, the loading device 100 is moved along the first horizontal direction X1 by manual pushing.

[0075] When the mounting bracket 521 rotates to the second position, the friction wheel 523 abuts against the first guide rail 10. At this time, the handling equipment switches to automatic drive mode, that is, the friction wheel 523 is automatically driven to rotate by the rotation drive component 528, thereby using the friction between the friction wheel 523 and the first guide rail 10 to drive the loading device 100 to move along the first horizontal direction X1.

[0076] Furthermore, the moving drive mechanism 50 also includes a switching drive member 527 connected between the mounting bracket 521 and the movable seat 51. This switching drive member 527 drives the mounting bracket 521 to rotate relative to the movable seat 51 around the mounting shaft 525, thereby causing the mounting bracket 521 to rotate between a first position and a second position around the mounting shaft 525. Thus, when the handling equipment needs to switch to manual drive mode, the switching drive member 527 drives the mounting bracket 521 to rotate around the mounting shaft 525 to the first position, causing the mounting bracket 521 to cause the friction wheel 523 to separate from the first guide rail 10. When the handling equipment needs to switch to automatic drive mode, the switching drive member 527 drives the mounting bracket 521 to rotate around the mounting shaft 525 to the second position, causing the mounting bracket 521 to cause the friction wheel 523 to abut against the first guide rail 10.

[0077] Specifically, the switching drive 527 includes a drive body 5271 and a telescopic end 5273 that can extend or retract relative to the drive body 5271. The drive body 5271 of the switching drive 527 is hinged to one of the mounting bracket 521 and the movable base 51, and the telescopic end 5273 of the switching drive 527 is hinged to the other of the mounting bracket 521 and the movable base 51. Figure 2 In the embodiment shown, the drive body 5271 of the switching drive 527 is glued to the mounting bracket 521, and the telescopic end 5273 of the switching drive 527 is hinged to the movable seat 51.

[0078] Thus, when the telescopic end 5273 of the switching drive component 527 extends relative to the drive component body 5271, it can drive the mounting bracket 521 to rotate relative to the mounting shaft 525, causing the mounting bracket 521 to drive the friction wheel 523 to swing away from the first guide rail 10 until the friction wheel 523 separates from the first guide rail 10. When the telescopic end 5273 of the switching drive component 527 retracts relative to the drive component body 5271, it can drive the mounting bracket 521 to rotate relative to the mounting shaft 525, causing the mounting bracket 521 to drive the friction wheel 523 to swing towards the first guide rail 10 until the friction wheel 523 abuts against the first guide rail 10.

[0079] Optionally, the switching drive 527 can be a cylinder. Of course, in other embodiments, the switching drive 527 can also be an electric telescopic rod, etc., as long as it can drive the mounting bracket 521 to rotate between the first position and the second position, and there is no limitation here.

[0080] In a specific embodiment, the mounting bracket 521 has a first end and a second end that are opposite to each other. The first end of the mounting bracket 521 is mounted on the mounting shaft 525, and the second end of the mounting bracket 521 is hinged to the drive body 5271 of the switching drive member 527. The friction wheel 523 is rotatably connected to the mounting bracket 521 and is located between the first end and the second end, so that when the switching drive member 527 drives the mounting bracket 521 to rotate around the mounting shaft 525, the mounting bracket 521 can drive the friction wheel 523 to swing closer to or away from the first guide rail 10.

[0081] In an embodiment of this application, the connecting unit 50e further includes a stopping mechanism (not shown in the figure), which includes a stopping drive 5291 and an abutment block 5293. The stopping drive 5291 is fixedly disposed relative to the movable seat 51, and the abutment block 5293 is installed on the driving end of the stopping drive 5291, so that the stopping drive 5291 can drive the abutment block 5293 to abut or separate from the first guide rail 10. Thus, when the loading device 100 moves into position along the first horizontal direction X1, the friction wheel 523 is controlled to stop rotating, and at the same time, the stopping drive 5291 drives the abutment block 5293 to abut against the first guide rail 10, thereby stopping the movable seat 51 from moving along the first guide rail 10, and thus stopping the loading device 100 from moving along the first horizontal direction X1. Optionally, the stopping drive 5291 can be a cylinder.

[0082] In a specific embodiment, two second guide rails 20 are provided, arranged parallel to each other and opposite to each other. Both second guide rails 20 are connected to the aforementioned movable seat 51, and a crossbeam is fixedly connected between the two second guide rails 20, so that the two second guide rails 20 and the crossbeam are fixedly connected as a whole. The aforementioned stop drive component 5291 can be fixedly installed on the crossbeam.

[0083] In the embodiments of this application, the first guide rail 10 has a horizontally arranged support wall and two vertically arranged guide walls. The two guide walls are arranged opposite to each other and spaced apart along a second horizontal direction X2, and the support wall is located between the two guide walls. Both the support wall and the guide walls extend longitudinally along a first horizontal direction X1. The moving drive mechanism 50 also includes a support wheel 511, which is rotatably connected to the moving seat 51 and supported on the support wall of the first guide rail 10. Thus, the moving seat 51 moves relative to the first guide rail 10 along the first horizontal direction X1 by the rolling of the support wheel 511 along the support wall.

[0084] Furthermore, the first guide rail 10 has two supporting walls, which are spaced apart from each other along the second horizontal direction X2 and are both located between the two guide walls. Support wheels 511 are mounted on both sides of the movable seat 51 in the second horizontal direction X2. The support wheels 511 on both sides of the movable seat 51 in the second horizontal direction X2 support the two supporting walls of the first guide rail 10, thereby making the movement of the movable seat 51 along the first guide rail 10 more stable and smooth.

[0085] Furthermore, multiple support wheels 511 are installed on both sides of the movable base 51 in the second horizontal direction X2. The multiple support wheels 511 on the same side of the movable base 51 are arranged at intervals along the first horizontal direction X1 and are all supported on the corresponding support wall. In this way, by using multiple support wheels 511 on both sides to support the support wall, the movement of the movable base 51 along the first guide rail 10 is made more stable and smooth.

[0086] Specifically, in this embodiment, the moving drive mechanism 50 further includes a guide wheel 513 rotatably connected to the moving seat 51, located between two guide walls of the first guide rail 10. The axial direction of the guide wheel 513 is perpendicular to the axial direction of the support wheel 511; that is, the axial direction of the guide wheel 513 is parallel to the vertical direction, while the axial direction of the support wheel 511 is parallel to the second horizontal direction X2. Thus, when the moving seat 51 moves along the first guide rail 10, the guide wheel 513 is confined between the two guide walls, thereby guiding the movement of the moving seat 51 along the first horizontal direction X1 and preventing the moving seat 51 from deviating.

[0087] Furthermore, the number of guide wheels 513 is at least two, and each guide wheel 513 is arranged at intervals along the first horizontal direction X1 on the movable seat 51. In this way, the movable seat 51 is guided by each guide wheel 513 simultaneously, further improving the guiding effect.

[0088] Please see Figures 1 to 3 In the embodiments of this application, the suspension mechanism 70 includes a first connecting seat 51a, a pivot shaft 52a, a non-metallic isolation sleeve 53a, and a first fixed seat 54a. The first connecting seat 51a is fixedly connected to the movable seat 51, and the first connecting seat 51a has a mounting groove A. The pivot shaft 52a passes through the mounting groove A on the first connecting seat 51a. The first fixed seat 54a is connected to both ends of the pivot shaft 52a, so that the first fixed seat 54a is suspended on the first connecting seat 51a through the pivot shaft 52a. The non-metallic isolation sleeve 53a is sleeved between the outer side of the pivot shaft 52a and the inner wall of the mounting groove A, so that the non-metallic isolation sleeve 53a separates the pivot shaft 52a and the first connecting seat 51a, avoiding direct contact between the two and friction that would generate metal dust.

[0089] Specifically, the non-metallic isolation sleeve 53a is elastic, which allows a certain amount of floating between the first connecting seat 51a and the pivot shaft 52a, thereby compensating for errors and helping to reduce manufacturing and assembly difficulties.

[0090] Specifically, the non-metallic isolation sleeve 53a is a plastic sleeve, which serves two purposes: firstly, it isolates the pivot shaft 52a from the first connecting seat 51a, preventing the generation of metal powder due to wear; secondly, the plastic sleeve has a certain degree of elasticity, which can compensate for errors, thereby reducing manufacturing and assembly difficulties. Optionally, the non-metallic isolation sleeve 53a can be made of polyurethane.

[0091] In some embodiments, the first fixing seat 54a includes a first side plate 541a, a bottom plate 545a, and a second side plate 543a. The first side plate 541a and the second side plate 543a are arranged opposite to each other, and the bottom plate 545a is connected between the first side plate 541a and the second side plate 543a, so that the first side plate 541a, the bottom plate 545a, and the second side plate 543a are connected as a whole. The bottom plate 545a is fixedly connected to the second guide rail 20. A first through hole is provided on both the first side plate 541a and the second side plate 543a, and the two ends of the pivot shaft 52a are respectively passed through the first through holes on the first side plate 541a and the second side plate 543a, so that the first fixing seat 54a is suspended on the first connecting seat 51a through the pivot shaft 52a. It should be noted that the first side plate 541a, the bottom plate 545a, and the second side plate 543a can be integrally formed, for example, by bending. In other embodiments, the first side plate 541a, the bottom plate 545a, and the second side plate 543a can also be fixed together as a whole by welding or other assembly methods.

[0092] Specifically, in this embodiment, the pivot shaft 52a includes a shaft body and a head (not shown) fixedly connected to one end of the shaft body. The shaft body passes through a first through hole on the first side plate 541a, a mounting groove A on the first connecting seat 51a, and a first through hole on the second side plate 543a. A non-metallic isolation sleeve 53a is fitted between the shaft body and the inner wall of the mounting groove A, thereby isolating the shaft body from the first connecting seat 51a and preventing the generation of metal dust. The head of the pivot shaft 52a is located on the side of the first side plate 541a opposite to the second side plate 543a, and the radial dimension of the head is larger than the radial dimension of the first through hole on the first side plate 541a, thereby preventing the head from passing through the first through hole on the first side plate 541a. The suspension mechanism 70 also includes a first locking nut 58a. The first locking nut 58a is threadedly connected to the end of the shaft body opposite to the head and is located on the side of the second side plate 543a opposite to the first side plate 541a. Thus, by tightening the first locking nut 58a, the first locking nut 58a and the head together clamp the first side plate 541a and the second side plate 543a of the first fixed seat 54a, thereby locking the first fixed seat 54a, the pivot shaft 52a and the first locking nut 58a into one unit, preventing the pivot shaft 52a from detaching from the first fixed seat 54a. When disassembly is required, the first locking nut 58a is unscrewed from the shaft body, and then the pivot shaft 52a is pulled out.

[0093] Furthermore, a first through hole 5211a extending radially along the shaft body is provided at the end of the shaft body away from the head. The suspension mechanism 70 also includes a first limiting pin 59a inserted into the first through hole 5211a. A first locking nut 58a is located between the second side plate 543a and the first limiting pin 59a, thereby preventing the first locking nut 58a from falling off from the end of the shaft body away from the head when it loosens.

[0094] In some embodiments, the first connecting seat 51a is U-shaped. That is, the first connecting seat 51a includes a first ear plate 511a, an arc-shaped plate 515a, and a second ear plate 513a. The first ear plate 511a and the second ear plate 513a are arranged opposite to each other, and the arc-shaped plate 515a connects the first ear plate 511a and the second ear plate 513a, so that the first ear plate 511a, the arc-shaped plate 515a, and the second ear plate 513a together enclose the aforementioned mounting groove A. Both the first ear plate 511a and the second ear plate 513a are fixedly connected to the movable seat 51. A pivot shaft 52a is disposed through the mounting groove A, that is, the pivot shaft 52a is located between the first ear plate 511a and the second ear plate 513a, and is located above the arc-shaped plate 515a.

[0095] It should be noted that the first ear plate 511a, the arc plate 515a, and the second ear plate 513a of the first connecting seat 51a can be integrally formed, for example, by stamping and bending. Of course, in other embodiments, the first ear plate 511a, the arc plate 515a, and the second ear plate 513a of the first connecting seat 51a can also be fixed together as a whole by assembly processes such as welding.

[0096] Specifically, in this embodiment, a portion of the movable seat 51 is located between the first ear plate 511a and the second ear plate 513a, and this portion is named the connecting portion. The first ear plate 511a, the second ear plate 513a, and the connecting portion are all provided with second through holes. The suspension mechanism 70 also includes a connector 55a, which is configured to pass through the second through holes in the first ear plate 511a, the connecting portion, and the second ear plate 513a, thereby enabling the first connecting seat 51a to be suspended on the movable seat 51 using the connector 55a. Preferably, the connector 55a is configured to pass through the second through holes in the first ear plate 511a, the connecting portion, and the second ear plate 513a in a direction perpendicular to the axial direction of the pivot shaft 52a.

[0097] Specifically, the connector 55a includes a rod portion 551a and a limiting portion 553a fixedly connected to one end of the rod portion 551a. The rod portion 551a has a second through hole passing through the first ear plate 511a, the connecting portion, and the second ear plate 513a. The limiting portion 553a is located on the side of the first ear plate 511a opposite to the second ear plate 513a, and the radial dimension of the limiting portion 553a is larger than the radial dimension of the second through hole on the first ear plate 511a, thereby preventing the limiting portion 553a from passing through the second through hole on the first ear plate 511a. The suspension mechanism 70 also includes a second locking nut 56a threadedly connected to the end of the rod portion 551a opposite to the limiting portion 553a, and the second locking nut 56a is located on the side of the second ear plate 513a opposite to the first ear plate 511a. Thus, by tightening the second locking nut 56a, the second locking nut 56a and the limiting part 553a together clamp the first ear plate 511a and the second ear plate 513a of the first connecting seat 51a, thereby locking and fixing the first connecting seat 51a, the connecting piece 55a and the second locking nut 56a into one piece, preventing the connecting piece 55a from detaching from the first connecting seat 51a. When disassembly is required, the second locking nut 56a can be unscrewed from the rod 551a, and then the connecting piece 55a can be pulled out.

[0098] Furthermore, a second through hole extending radially along the rod portion 551a is provided at the end of the rod portion 551a away from the limiting portion 553a. The suspension mechanism 70 also includes a second limiting pin 57a ​​inserted into the second through hole. The second locking nut 56a is located between the second ear plate 513a and the second limiting pin 57a, thereby preventing the second locking nut 56a from falling off from the end of the rod portion 551a away from the limiting portion 553a when it loosens.

[0099] In a specific embodiment, at least two connectors 55a are provided, and each connector 55a is spaced apart along a direction parallel to the axial direction of the pivot shaft 52a. In this way, the first connecting seat 51a is simultaneously locked and fixed to the movable seat 51 by each connector 55a, making the fixation between the movable seat 51 and the first connecting seat 51a more secure and reliable. Figure 3 In the illustrated embodiment, there are two connectors 55a. Of course, in other embodiments, the number of connectors 55a may be three or four, etc., and this is not limited here.

[0100] In the embodiments of this application, the loading device 100 includes a rotating mechanism 30, a lifting mechanism 40, and a loading mechanism 60. The rotating mechanism 30 is connected to the first fixed seat 54a of the corresponding suspension mechanism 70, so that the rotating mechanism 30 is suspended on the second guide rail 20 through the corresponding suspension mechanism 70 and the movable seat 51. The lifting mechanism 40 is connected to the drive end of the rotating mechanism 30, so that the rotating mechanism 30 can drive the lifting mechanism 40 to rotate. The loading mechanism 60 is connected to the drive end of the lifting mechanism 40, so that the lifting mechanism 40 can drive the loading mechanism 60 to rise or fall. Thus, the loading mechanism 60 is used to load material rolls, the rotating mechanism 30 can drive the loading mechanism 60 to rotate, and the lifting mechanism 40 can drive the loading mechanism 60 to rise or fall.

[0101] Please see Figure 5 and Figure 6 In some embodiments, the rotating mechanism 30 includes a second fixed base 10b, a slewing support bearing 20b, a turntable 30b, and a drive assembly. The slewing support bearing 20b includes a fixed ring 21b and a rotating ring 23b disposed on the fixed ring 21b. A rolling element is disposed between the fixed ring 21b and the rotating ring 23b, allowing the rotating ring 23b to rotate relative to the fixed ring 21b. It is understood that the rolling element can be a ball or a roller, as long as it enables the rotating ring 23b to rotate relative to the fixed ring 21b, and no special limitation is made here.

[0102] The second fixed seat 10b is connected to the first fixed seat 54a of the corresponding suspension mechanism 70. The fixed ring 21b of the slewing support bearing 20b is fixedly connected to the second fixed seat 10b, and the turntable 30b is fixedly connected to the rotating ring 23b of the slewing support bearing 20b, allowing the turntable 30b to rotate relative to the second fixed seat 10b. The drive assembly is mounted on the second fixed seat 10b and is connected to the turntable 30b in a transmission manner, enabling the drive assembly to drive the turntable 30b to rotate relative to the second fixed seat 10b. The loading mechanism 60 is mounted on the turntable 30b, allowing the loading mechanism 60 to rotate with the turntable 30b and adjust its orientation accordingly. Furthermore, the fixed ring 21b, the rotating ring 23b, and the turntable 30b are arranged coaxially to ensure smooth and stable rotation of the turntable 30b and the rotating ring 23b relative to the fixed ring 21b.

[0103] Thus, the turntable 30b is mounted on the second fixed seat 10b via the slewing support bearing 20b, enabling the turntable 30b to drive the loading mechanism 60 to rotate relative to the second fixed seat 10b, thereby adjusting the orientation of the loading mechanism 60. Since the slewing support bearing 20b has the characteristic of strong axial load bearing capacity, more material rolls can be loaded on the loading mechanism 60 at the same time, which greatly improves the load bearing capacity of the rotating mechanism 30, and thus helps to improve the handling efficiency of the material rolls.

[0104] In a specific embodiment, the fixed ring 21b is supported on the top surface of the second fixed base 10b and locked to the second fixed base 10b by a first locking member. The rotating ring 23b is supported on the top surface of the fixed ring 21b by rolling elements, thus allowing it to rotate relative to the fixed ring 21b. The turntable 30b is supported on the top surface of the rotating ring 23b and locked to the rotating ring 23b by a second locking member. Thus, the turntable 30b, rotating ring 23b, fixed ring 21b, and second fixed base 10b are arranged sequentially from top to bottom, allowing the load on the loading mechanism 60 to be transferred sequentially from top to bottom to the second fixed base 10b. This improves the load-bearing capacity of the rotating mechanism 30 and thus enhances the handling efficiency of the material roll.

[0105] Optionally, the first locking element can be a locking screw. Specifically, the fixing ring 21b has a first mounting hole 211b, and the second fixing seat 10b has a first threaded hole (not shown). The first locking element passes through the first mounting hole 211b on the fixing ring 21b and is threadedly connected to the second fixing seat 10b through the first threaded hole, thereby locking the fixing ring 21b onto the second fixing seat 10b.

[0106] Furthermore, the fixing ring 21b has multiple first mounting holes 211b, which are spaced apart circumferentially along the fixing ring 21b. The second fixing seat 10b also has multiple first threaded holes, each corresponding to a specific first mounting hole 211b. Multiple first locking members are also present, each corresponding to a specific first mounting hole 211b, and threadedly connected to the second fixing seat 10b through a corresponding first threaded hole. Thus, the fixing ring 21b is locked and fixed to the second fixing seat 10b by the multiple first locking members.

[0107] Optionally, the second locking element can be a locking screw. Specifically, the turntable 30b has a second mounting hole 31b, and the rotating ring 23b has a second threaded hole 231b. The second locking element passes through the second mounting hole 31b on the turntable 30b and is threadedly connected to the rotating ring 23b through the second threaded hole 231b, thereby locking the turntable 30b onto the rotating ring 23b.

[0108] Furthermore, the turntable 30b has multiple second mounting holes 31b, which are spaced apart circumferentially on the turntable 30b. The rotating ring 23b also has multiple second threaded holes 231b, each corresponding to a different second mounting hole 31b. Multiple second locking elements are also present, each passing through a corresponding second mounting hole 31b and threadedly connected to the rotating ring 23b through a corresponding second threaded hole 231b. Thus, the turntable 30b is locked and fixed to the rotating ring 23b by the combined action of multiple second locking elements.

[0109] In the embodiments of this application, the driving assembly includes a first rotary drive member 41b, a driving gear (not shown), and a driven gear 43b. The first rotary drive member 41b is disposed on the second fixed base 10b, and the driving gear is mounted on the output shaft of the first rotary drive member 41b, thereby enabling the first rotary drive member 41b to drive the driving gear to rotate. The driven gear 43b is mounted on the turntable 30b. Preferably, the driven gear 43b and the turntable 30b are arranged coaxially, so that the driven gear 43b and the turntable 30b can rotate synchronously. The driven gear 43b meshes with the driving gear, thereby enabling the driving gear to drive the driven gear 43b to rotate. Thus, when it is necessary to adjust the orientation of the loading mechanism 60, the first rotary drive member 41b drives the driving gear to rotate, the driving gear drives the driven gear 43b to rotate, the driven gear 43b then drives the turntable 30b to rotate together, and the turntable 30b then drives the loading mechanism 60 to rotate until the orientation of the loading mechanism 60 is adjusted to the correct position. Optionally, the first rotary drive 41b may be an electric motor.

[0110] Optionally, the driven gear 43b can be made of nylon. In this way, compared with gears made of metal, the use of nylon gears in this application reduces the weight of the driven gear 43b, thereby reducing the weight of the rotating mechanism 30, which is conducive to better meeting the lightweight design requirements; on the other hand, it avoids the generation of metal powder, thereby avoiding the adverse effects of metal powder on the material roll.

[0111] Optionally, the drive gear can be made of nylon. In this way, compared with gears made of metal, the use of nylon gears in this application reduces the weight of the drive gear, thereby reducing the weight of the rotating mechanism 30, which is conducive to better meeting the lightweight design requirements; on the other hand, it avoids the generation of metal powder, thereby avoiding the adverse effects of metal powder on the material roll.

[0112] In the embodiments of this application, the rotating mechanism 30 further includes a mounting bracket 55b, an electrical slip ring 60b, a first electrical circuit (not shown), and a second electrical circuit 70b. The mounting bracket 55b is fixedly connected to the second fixed base 10b, and the electrical slip ring 60b is mounted on the mounting bracket 55b. The first electrical circuit is disposed on the turntable 30b, and the second electrical circuit 70b is connected to the first electrical circuit through the electrical slip ring 60b. The second electrical circuit 70b is used to connect to an external air source and a power source, and the first electrical circuit is used to connect to electrical components mounted on the turntable 30b, such that high-pressure gas provided by the external air source is sequentially transmitted through the second electrical circuit 70b, the electrical slip ring 60b, and the first electrical circuit to the electrical components (e.g., a cylinder) mounted on the turntable 30b; and electrical energy provided by the external power source is sequentially transmitted through the second electrical circuit 70b, the electrical slip ring 60b, and the first electrical circuit to the electrical components (e.g., a motor) mounted on the turntable 30b. Thus, by using an electrical slip ring 60b to connect the first electrical circuit and the second electrical circuit 70b, the first electrical circuit remains connected to the second electrical circuit 70b even as the turntable 30b rotates, preventing wire entanglement. It is understood that both the first and second electrical circuits 70b can include wires for circuit connection and air pipes for air connection.

[0113] Furthermore, the mounting bracket 55b includes a first support section 51b, a second support section 53b, and a mounting section 55b connecting the first support section 51b and the second support section 53b. The end of the first support section 51b furthest from the mounting section 55b is fixedly connected to the second fixed base 10b, and the end of the second support section 53b furthest from the mounting section 55b is also fixedly connected to the second fixed base 10b. The turntable 30b is located between the first support section 51b and the second support section 53b. The mounting section 55b is located above the turntable 30b, and an electrical slip ring 60b is mounted on the mounting section 55b of the mounting bracket 55b.

[0114] Please see Figures 7 to 9 In the embodiments of this application, the lifting mechanism 40 includes a mounting base 10c, a lifting seat 20c, and a lifting drive assembly (not shown in the figure). The mounting base 10c is fixedly connected to the turntable 30b of the rotating mechanism 30, and the lifting seat 20c is vertically connected to the mounting base 10c. The loading mechanism 60 is mounted on the lifting seat 20c, so that when the lifting seat 20c moves relative to the mounting base 10c, it can drive the loading mechanism 60 to move up and down. The lifting drive assembly includes a sprocket (not shown in the figure), a third rotary drive member 31c, and a ring chain 33c. The sprocket is rotatably connected to the mounting base 10c. The third rotary drive member 31c is mounted on the mounting base 10c and is drivenly connected to the sprocket, so that the third rotary drive member 31c can drive the sprocket to rotate relative to the mounting base 10c. The ring chain 33c is wound around the sprocket, so that when the sprocket rotates, it can drive the ring chain 33c to move up and down. One end of the ring chain 33c is connected to the lifting seat 20c, so that the ring chain 33c can drive the lifting seat 20c to rise and fall when it rises and falls.

[0115] In actual use, the aforementioned lifting mechanism 40 utilizes the third rotary drive component 31c to drive the sprocket to rotate. The sprocket drives the ring chain 33c to rise or fall, which in turn drives the lifting seat 20c to rise or fall relative to the mounting seat 10c. The lifting seat 20c then drives the loading mechanism 60 to rise or fall, thus achieving vertical position adjustment of the loading mechanism 60. After the loading mechanism 60 is in the correct vertical position, the material roll is either loaded onto the loading mechanism 60 or unloaded from the loading mechanism 60.

[0116] Thus, the loading mechanism 60 is installed on the lifting seat 20c, and the lifting seat 20c and the loading mechanism 60 are supported by the ring chain 33c. The lifting seat 20c and the loading mechanism 60 are lifted and lowered by the rotation of the sprocket. The sprocket and the ring chain 33c have strong load-bearing capacity, and the transmission structure of the sprocket and the ring chain 33c is compact and low in cost. This is beneficial to improving the load-bearing capacity of the lifting mechanism 40, reducing the space required by the lifting mechanism 40, and reducing the cost of the lifting mechanism 40.

[0117] Understandably, the ring chain 33c 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 40. The sprocket is a wheel with interlocking teeth that meshes with the metal rings of the ring chain 33c, allowing the sprocket to rotate and drive the ring chain 33c to rise or fall.

[0118] In a specific embodiment, the lifting drive assembly further includes a chain box 40c mounted on the mounting base 10c. A ring chain 33c is wound around a sprocket, with both ends extending downwards. One end of the ring chain 33c is connected to the lifting seat 20c, and the other end is connected to the chain box 40c. The chain box 40c stores the ring chain 33c. Thus, when the sprocket rotates and drives the lifting seat 20c to rise via the ring chain 33c, the portion of the ring chain 33c between the sprocket and the lifting seat 20c shortens, while the portion between the sprocket and the chain box 40c lengthens, and the lengthened portion of the ring chain 33c is stored in the chain box 40c. When the sprocket rotates and drives the lifting seat 20c to fall via the ring chain 33c, the portion of the ring chain 33c between the sprocket and the lifting seat 20c lengthens, while the portion between the sprocket and the chain box 40c shortens.

[0119] Furthermore, at least two sprockets, at least two ring chains 33c, and at least two chain boxes 40c are provided. Each sprocket is rotatably connected to the mounting base 10c, and each ring chain 33c is wound around the corresponding sprocket, with both ends of each ring chain 33c extending downwards. One end of each ring chain 33c is connected to the lifting seat 20c, and the other end of each ring chain 33c is connected to a corresponding chain box 40c. Each chain box 40c is used to store a corresponding ring chain 33c. In this way, by using at least two ring chains 33c to jointly support the lifting seat 20c and jointly drive the lifting seat 20c to rise or fall, the load-bearing capacity of the lifting mechanism 40 is further improved.

[0120] Furthermore, the lifting drive assembly also includes a rotating shaft 35c, which is rotatably connected to the mounting base 10c. This rotating shaft 35c is drive-connected to a third rotating drive member 31c, enabling the third rotating drive member 31c to drive the rotating shaft 35c to rotate relative to the mounting base 10c about its own axis. Each sprocket is mounted on the rotating shaft 35c, allowing the rotating shaft 35c to drive each sprocket to rotate, thereby causing each sprocket to raise or lower the lifting seat 20c via its respective ring chain 33c.

[0121] Specifically, in this embodiment, the lifting drive assembly further includes a transmission unit (not shown), which comprises a worm and a worm gear. The worm is mounted on the drive end of the third rotary drive member 31c, enabling the third rotary drive member 31c to drive the worm to rotate. The worm gear is mounted on the rotating shaft 35c, enabling the worm gear to drive the rotating shaft 35c to rotate. The worm and worm gear mesh with each other. Thus, when the third rotary drive member 31c drives the worm to rotate, the worm gear drives the worm gear to rotate, the worm gear drives the rotating shaft 35c to rotate, the rotating shaft 35c drives each sprocket to rotate, and each sprocket drives the lifting seat 20c to rise or fall via its corresponding ring chain 33c. The lifting seat 20c then drives the loading mechanism 60 to rise or fall. Optionally, the third rotary drive member 31c can be a motor.

[0122] It should be noted that the transmission unit uses a worm gear and a worm shaft 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 40. The worm gear and worm shaft transmission also has a self-locking function, which can prevent the lifting seat 20c, the loading mechanism 60, and the material rolls on the loading mechanism 60 from falling.

[0123] 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 third rotary drive 31c to the rotary shaft 35c, which is not limited here.

[0124] In some embodiments, the lifting mechanism 40 further includes a connecting assembly 50c, which includes a second connecting seat 51c, a hinge shaft 52c, and a hinge base 53c. Two ring chains 33c are provided, one end of which is connected to one end of the second connecting seat 51c, and the other end of which is connected to the other end of the second connecting seat 51c. The second connecting seat 51c has a hinge hole located between its two ends, that is, approximately in the middle of the second connecting seat 51c. The hinge shaft 52c passes through the hinge hole in the second connecting seat 51c, and the hinge base 53c is hingedly connected to the second connecting seat 51c via the hinge shaft 52c, and is connected to the lifting seat 20c. Thus, when the two ring chains 33c together drive the second connecting seat 51c to rise or fall, the second connecting seat 51c drives the hinge seat 53c to rise or fall through the hinge shaft 52c, and the hinge seat 53c then drives the lifting seat 20c to rise or fall.

[0125] Please see Figures 9 to 11In the embodiments of this application, the mounting base 10c has a guide channel that extends through the top and bottom of the mounting base 10c. The lifting seat 20c extends through the guide channel of the mounting base 10c and is slidably connected to the mounting base 10c, meaning that the lifting seat 20c can move up and down along the guide channel of the mounting base 10c. One end of the lifting seat 20c protruding from the bottom of the mounting base 10c is used to install the loading mechanism 60. Thus, by fitting the lifting seat 20c within the guide channel of the mounting base 10c, it serves two purposes: firstly, it guides the lifting seat 20c, making its lifting movement smoother; secondly, it saves space, making the structure more compact and further reducing the space required for the lifting mechanism 40.

[0126] Optionally, the lifting seat 20c is provided with a slide rail 21c, and the inner wall of the mounting base 10c is provided with a slider 110c. The slider 110c slides with the slide rail 21c, thereby guiding the lifting of the lifting seat 20c by sliding the slider 110c along the slide rail 21c.

[0127] In a specific embodiment, the lifting mechanism 40 further includes a first limiting block 61c and a first stop block 63c. The first limiting block 61c is fixedly connected to the lifting seat 20c, and the first stop block 63c is fixedly connected to the mounting seat 10c. When the lifting seat 20c rises relative to the mounting seat 10c, it can cause the first limiting block 61c to engage with the first stop block 63c, thereby preventing the lifting seat 20c from rising further relative to the mounting seat 10c, that is, limiting the lifting seat 20c to the upper limit position.

[0128] In a specific embodiment, the lifting mechanism 40 further includes a second limiting block 65c and a second stop block 67c. The second limiting block 65c is fixedly connected to the lifting seat 20c, and the second stop block 67c is fixedly connected to the mounting seat 10c. When the lifting seat 20c descends relative to the mounting seat 10c, it can cause the second limiting block 65c to engage with the second stop block 67c, thereby preventing the lifting seat 20c from descending further relative to the mounting seat 10c, that is, limiting the lifting seat 20c to the lower limit position.

[0129] It should be noted that the lifting and lowering of the lifting seat 20c is limited between the upper limit position and the lower limit position by the first limit block 61c, the first stop block 63c, the second limit block 65c and the second stop block 67c, so as to prevent the lifting seat 20c from detaching from the mounting seat 10c due to excessive stroke.

[0130] Optionally, the first limiting block 61c is installed at the bottom end of the lifting seat 20c, and the first stop block 63c is installed at the bottom end of the mounting base 10c. When the lifting seat 20c rises to its upper limit position relative to the mounting base 10c, the first limiting block 61c and the first stop block 63c engage to stop the lifting seat 20c from rising further. In other embodiments, the first limiting block 61c may also be installed at other parts of the lifting seat 20c, and the first stop block 63c may also be installed at other parts of the mounting base 10c, as long as it can limit the lifting seat 20c when it rises to its upper limit position.

[0131] Optionally, the second limiting block 65c is installed at the top of the lifting seat 20c and on the inner wall of the mounting base 10c, located between the top and bottom ends of the mounting base 10c. When the lifting seat 20c descends to its lower limit position relative to the mounting base 10c, the second limiting block 65c engages with the second stop block 67c to prevent the lifting seat 20c from descending further. In other embodiments, the second limiting block 65c may also be installed at other parts of the lifting seat 20c, and the second stop block 67c may also be installed at other parts of the mounting base 10c, as long as it can limit the descent of the lifting seat 20c to its lower limit position.

[0132] Optionally, the first stop block 63c is a first elastic block, that is, the first stop block 63c is elastic. In this way, it can buffer the impact force between the first limiting block 61c and the first stop block 63c, and avoid hard impact between the first limiting block 61c and the first stop block 63c.

[0133] Optionally, the second stop block 67c is a second elastic block, that is, the second stop block 67c is elastic. In this way, it can buffer the impact force between the second limit block 65c and the second stop block 67c, and avoid hard impact between the second limit block 65c and the second stop block 67c.

[0134] Please see Figures 12 to 15 In an embodiment of this application, the loading mechanism 60 includes a loading shaft 10d and a feeding assembly 30d. The loading shaft 10d is connected to the lifting seat 20c of the lifting mechanism 40 and is used to load at least one roll of material. The rolls loaded on the loading shaft 10d are arranged along the axial direction of the loading shaft 10d. The loading shaft 10d can also move to axially align with a preparation shaft (not shown). The feeding assembly 30d is disposed on the loading shaft 10d and is used to push the rolls on the loading shaft 10d to move axially, so that the rolls on the loading shaft 10d are pushed away from the loading shaft 10d one by one and reach the preparation shaft, thus realizing the transfer of the rolls on the loading shaft 10d to the preparation shaft.

[0135] The feeding assembly 30d includes a feeding block 31d, a belt drive unit 33d, and a feeding drive member 35d. The feeding block 31d is movably connected to the loading shaft 10d along its axial direction, allowing it to push each roll of material on the loading shaft 10d to move axially along the shaft, thereby pushing each roll of material off the shaft one by one. Both the feeding drive member 35d and the belt drive unit 33d are mounted on the loading shaft 10d, and the belt drive unit 33d is drively connected between the feeding drive member 35d and the feeding block 31d. This allows the feeding drive member 35d to drive the feeding block 31d to move axially along the loading shaft 10d via the belt drive unit 33d; that is, the belt drive unit 33d transmits the power provided by the feeding drive member 35d to the feeding block 31d.

[0136] In actual use, the aforementioned loading mechanism 60 first loads the material roll onto the loading shaft 10d using a feeding mechanism or manually. Then, the loading shaft 10d is driven to move by the motion drive device 200, the rotation mechanism 30, and the lifting mechanism 40 until the loading shaft 10d is axially aligned with the preparation shaft. Next, the feeding drive component 35d drives the feeding block 31d to move along the axial direction of the loading shaft 10d toward the preparation shaft via the belt drive unit 33d until part or all of the material roll on the loading shaft 10d is pushed onto the preparation shaft, thus realizing the transfer of the material roll on the loading shaft 10d to the preparation shaft.

[0137] Thus, the transmission between the feeding drive component 35d and the feeding block 31d is realized by the belt drive unit 33d installed on the feeding shaft 10d. The belt drive unit 33d has the characteristics of simple assembly and small space occupation. It is not necessary to install the belt drive unit 33d inside the feeding shaft 10d, thereby avoiding the need to use a modular feeding shaft 10d (i.e., a feeding shaft 10d assembled from at least two parts). An integrated feeding shaft 10d can be used, which is beneficial to improve the strength of the feeding shaft 10d and thus enhance the load-bearing capacity of the feeding shaft 10d.

[0138] In the embodiments of this application, the belt drive unit 33d includes a driving pulley 331d, a driven pulley 333d, and a drive belt 335d. The driving pulley 331d is mounted on the output shaft of the feeding drive member 35d, thereby enabling the feeding drive member 35d to drive the driving pulley 331d to rotate. The driven pulley 333d is rotatably connected to the loading shaft 10d and is spaced apart from the driving pulley 331d along the axial direction of the loading shaft 10d. The drive belt 335d is tensioned and sleeved between the driving pulley 331d and the driven pulley 333d, so that the driving pulley 331d can drive the drive belt 335d to move between the driving pulley 331d and the driven pulley 333d. The feeding block 31d is fixedly connected to the drive belt 335d, thereby enabling the drive belt 335d to drive the feeding block 31d to move along the axial direction of the loading shaft 10d. Thus, when material needs to be pushed, the feeding drive 35d drives the drive pulley 331d to rotate. The drive pulley 331d drives the transmission belt 335d to move between the drive pulley 331d and the driven pulley 333d, that is, to move axially along the loading shaft 10d. The transmission belt 335d then drives the feeding block 31d to move axially along the loading shaft 10d until the feeding block 31d pushes the material roll on the loading shaft 10d axially away from the loading shaft 10d. Optionally, the feeding drive 35d can be a motor, the drive pulley 331d and the driven pulley 333d can be synchronous pulleys, and the transmission belt 335d can be a synchronous belt.

[0139] Furthermore, the loading mechanism 60 also includes a base 20d, and the loading shaft 10d has a mounting end a1 and an inlet / outlet end a2 as its two axial ends. The base 20d is mounted on the mounting seat 10c, the mounting end a1 of the loading shaft 10d is fixedly connected to the base 20d, and the inlet / outlet end a2 is used for feeding the material roll through, that is, the material roll is loaded onto the loading shaft 10d through the inlet / outlet end a2, or the material roll on the loading shaft 10d leaves the loading shaft 10d through the inlet / outlet end a2 under the pushing action of the feeding block 31d. Thus, in actual use, firstly, the loading shaft 10d is controlled to move until the inlet / outlet end a2 of the loading shaft 10d is axially aligned with the preparation shaft; then, the feeding drive 35d drives the drive pulley 331d to rotate, the drive pulley 331d drives the transmission belt 335d to move axially along the loading shaft 10d, and the transmission belt 335d drives the feeding block 31d to move axially along the loading shaft 10d toward the preparation shaft, thereby pushing each roll of material on the loading shaft 10d toward the inlet / outlet end a2 until some or all of the rolls of material on the loading shaft 10d are pushed onto the preparation shaft, thus realizing the transfer of the rolls of material on the loading shaft 10d to the preparation shaft.

[0140] Furthermore, the driving pulley 331d is located at the mounting end a1 of the loading shaft 10d, and the driven pulley 333d is located at the inlet / outlet end a2 of the loading shaft 10d. This allows the transmission belt 335d, which is tensioned between the driving pulley 331d and the driven pulley 333d, to extend from the mounting end a1 of the loading shaft 10d to the inlet / outlet end a2 of the loading shaft 10d. Consequently, the transmission belt 335d can drive the material feeding block 31d to move between the mounting end a1 and the inlet / outlet end a2 of the loading shaft 10d. Since the driving pulley 331d is located at the mounting end a1 of the loading shaft 10d, the material feeding drive 35d is also located at the mounting end a1 of the loading shaft 10d, thereby avoiding interference from the material feeding drive 35d with the axial movement of the coil along the loading shaft 10d.

[0141] Furthermore, the loading shaft 10d is a hollow shaft, and the first portion 3351d of the drive belt 335d, located on the same side as the driving pulley 331d and the driven pulley 333d, is located inside the cavity of the loading shaft 10d. The second portion 3352d of the drive belt 335d, located on the other side of the driving pulley 331d and the driven pulley 333d, is located outside the loading shaft 10d. This second portion 3352d of the drive belt 335d is connected to the feeding block 31d. In this way, by utilizing the cavity of the loading shaft 10d to accommodate the first portion 3351d of the drive belt 335d, the radial space of the loading shaft 10d is further saved, making the structure more compact.

[0142] Furthermore, the peripheral surface of the loading shaft 10d has a first notch b1 and a second notch b2 that connect the inner cavity of the loading shaft 10d with the outer side. The driving pulley 331d is mounted on the output shaft of the feeding drive 35d and is located at the first notch b1. The driven pulley 333d is rotatably connected at the second notch b2. Thus, the portion of the drive belt 335d that winds around the side of the drive pulley 331d facing the inner cavity of the loading shaft 10d and the portion that winds around the side of the driven pulley 333d facing the inner cavity of the loading shaft 10d is the first portion 3351d, which is located inside the inner cavity of the loading shaft 10d; the portion of the drive belt 335d that winds around the side of the drive pulley 331d facing the outside of the loading shaft 10d and the portion that winds around the side of the driven pulley 333d facing the outside of the loading shaft 10d is the second portion 3352d, which is located outside the loading shaft 10d and connected to the feeding block 31d.

[0143] In the embodiments of this application, the feeding assembly 30d further includes a protective cover 37d, which is fixedly connected to the peripheral surface of the loading shaft 10d. The second portion 3352d of the transmission belt 335d is located inside the protective cover 37d, thereby protecting the second portion 3352d of the transmission belt 335d from adverse effects on its operation by external components. The protective cover 37d has a clearance groove 371d extending axially along the loading shaft 10d. A portion of the feeding block 31d passes through the clearance groove 371d into the protective cover 37d and connects with the second portion 3352d of the transmission belt 335d located within the protective cover 37d, allowing the transmission belt 335d to drive the feeding block 31d to move axially along the loading shaft 10d.

[0144] Furthermore, the feeding block 31d slides into the clearance groove 371d, thereby using the clearance groove 371d to guide the axial movement of the feeding block 31d along the loading shaft 10d, ensuring that the feeding action of the feeding block 31d is stable and reliable.

[0145] In a specific embodiment, there are two feeding components 30d, which are respectively arranged on opposite sides of the loading shaft 10d in the radial direction. In this way, the feeding blocks 31d of the two feeding components 30d simultaneously push each roll of material on the loading shaft 10d, making the feeding action more stable and reliable, and avoiding jamming of the rolls due to uneven force.

[0146] In a specific embodiment, the loading mechanism 60 further includes a plurality of support rollers 40d, each of which is rotatably connected to the loading shaft 10d. At least a portion of each support roller 511 protrudes from the circumferential upper surface of the loading shaft 10d. Thus, the material roll moving from the inlet / outlet end a2 of the loading shaft 10d to the loading shaft 10d is supported on the support rollers 40d, ensuring that the material roll can move more easily along the axial direction of the loading shaft 10d and avoiding direct contact between the material roll and the circumferential surface of the loading shaft 10d, which would cause greater wear.

[0147] Optionally, the support rollers 40d on the loading shaft 10d are divided into multiple groups, each group including multiple support rollers 40d. The support rollers 40d in each group are arranged at circumferential intervals along the loading shaft 10d, and the support rollers 40d in the same group are arranged in a row at axial intervals along the loading shaft 10d. Specifically... Figure 16 In the embodiment shown, the loading shaft 10d is provided with 3 sets of support rollers 40d, each set including 5 support rollers 40d.

[0148] Please see Figure 17Specifically, in this embodiment, the loading mechanism 60 further includes a tensioning drive member 50d and a tensioning block 60d. A receiving groove 101d is formed on the peripheral surface of the loading shaft 10d. The tensioning drive member 50d is installed within the receiving groove 101d, and the tensioning block 60d is connected to the driving end of the tensioning drive member 50d. The tensioning drive member 50d is used to drive the tensioning block 60d to extend out of or retract into the receiving groove 101d. Optionally, the tensioning drive member 50d can be a cylinder.

[0149] Thus, when the feeding block 31d is not needed to push the material roll, the tensioning drive 50d drives the tensioning block 60d to extend outside the receiving groove 101d, so that the tensioning block 60d abuts against the inner ring of the material roll, thereby tensioning the material roll on the loading shaft 10d and preventing the material roll from falling due to axial movement along the loading shaft 10d. When the feeding block 31d needs to push the material roll, firstly, the tensioning drive 50d drives the tensioning block 60d to retract into the receiving groove 101d, so that the tensioning block 60d separates from the material roll; then, the feeding block 31d moves along the axial direction of the loading shaft 10d, thereby pushing the material roll on the loading shaft 10d toward the inlet / outlet end a2 of the loading shaft 10d, until all or part of the material roll on the loading shaft 10d is pushed away from the loading shaft 10d and moved to the preparation shaft.

[0150] Preferably, the receiving groove 101d is formed on the lower peripheral surface of the loading shaft 10d. Thus, when the tensioning drive member 50d drives the tensioning block 60d to move downward, the tensioning block 60d extends out of the receiving groove 101d and abuts against the inner ring of the material roll, thereby tensioning the material roll on the loading shaft 10d; when the tensioning drive member 50d drives the tensioning block 60d to move upward, the tensioning block 60d retracts into the receiving groove 101d and separates from the material roll, thereby allowing the material roll to move axially along the loading shaft 10d under the pushing action of the feeding block 31d.

[0151] Preferably, a plurality of receiving grooves 101d are formed on the peripheral surface of the loading shaft 10d, and these receiving grooves 101d are arranged at intervals along the axial direction of the loading shaft 10d. Multiple tensioning drive members 50d are configured, and each tensioning drive member 50d is installed in a corresponding receiving groove 101d. Each tensioning drive member 50d has a tensioning block 60d connected to its driving end. Thus, by simultaneously driving each tensioning block 60d out of the receiving groove 101d using each tensioning drive member 50d, until each tensioning block 60d abuts against the inner ring of its corresponding material roll, thereby tensioning and fixing each material roll on the loading shaft 10d.
