[0038] Compared with the related art, the present application has at least the following beneficial effects:

Since the spare material tape is unwound from the spare material roll on the second unwinding shaft, after the cutting of the working material tape is completed, the splicing mechanism is used to splice the spare material tape clamped by the clamping mechanism and the cut working material tape clamped by the clamping mechanism, so as to realize the splicing of the spare material tape and the working material tape and complete the rewinding.

At this time, the spare material roll on the second unwinding shaft becomes the working material roll, that is, the working material roll is installed on the second unwinding shaft at this time. Since the working material roll on the first unwinding shaft has been completely unwound, a spare material roll can be installed on the first unwinding shaft to perform rewinding after the working material roll on the second unwinding shaft is completely unwound. The rewinding process in the case of installing a spare material roll on the first unwinding shaft and a working material roll on the second unwinding shaft is similar to the above-mentioned rewinding process and will not be repeated here.

[0041] Compared with the related art, in the present application, since the first unwinding shaft and the second unwinding shaft are arranged at intervals in the vertical direction, even if relatively large-diameter material rolls are installed on the first unwinding shaft and the second unwinding shaft, each material roll has a relatively small occupied space in the horizontal direction, and further, the rewinding device also has a relatively small occupied space in the horizontal direction, which is beneficial to facilitating the arrangement of the rewinding device in the horizontal direction.

[0061] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0063] Moreover, in addition to being used to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings.

[0065] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0066] As described in the background art of the present application, in a rewinding device, generally, a working material roll unwinds a material tape. When the working material roll is almost unwound, the material tape unwound from the working material roll is bonded to the material tape unwound from a spare material roll to continue unwinding the material tape.

[0067] However, in the related art, since the working material roll unwinding shaft and the spare material roll unwinding shaft are usually arranged at intervals in the horizontal direction, when the diameters of the material rolls on each unwinding shaft are relatively large, such as when the diameter of the material roll is 1 m, it will cause each material roll to have a large occupied space in the horizontal direction, and further cause the roll changing device to have a large occupied space in the horizontal direction.

[0068] Embodiment 1

[0069] In view of the above problems, the present application provides a roll changing device to solve the problem that the roll changing device has a large occupied space in the horizontal direction due to the working material roll unwinding shaft and the spare material roll unwinding shaft being arranged at intervals in the horizontal direction in the related art.

[0070] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings:

[0071] As Figure 1 and Figure 2 shown, the roll changing device 100 includes a mounting base 1, an unwinding mechanism 2, a material clamping mechanism 3, a cutting mechanism 4, and a tape splicing mechanism 5. Among them, the unwinding mechanism 2 includes a first unwinding shaft 21 and a second unwinding shaft 22 that are arranged at intervals in the vertical direction (such as the Z direction in Figure 1 ) on the mounting base 1. One of the first unwinding shaft 21 and the second unwinding shaft 22 is used to mount the working material roll 6, and the other is used to mount the spare material roll 7. The working material roll 6 is used to unwind the working material tape 61, and the spare material roll 7 is used to unwind the spare material tape 71.

[0072] The material clamping mechanism 3 is arranged on the mounting base 1, and the material clamping mechanism 3 is used to clamp the working material tape 61 and the spare material tape 71. The cutting mechanism 4 is arranged on the mounting base 1, and the cutting mechanism 4 is used to cut the working material tape 61 clamped by the material clamping mechanism 3. The tape splicing mechanism 5 is arranged on the mounting base 1, and the tape splicing mechanism 5 is used to splice the spare material tape 71 clamped by the material clamping mechanism 3 and the cut working material tape 61 clamped by the material clamping mechanism 3.

[0073] In the roll changing device 100 of the present application, as Figure 1As shown in the figure, if a working material roll 6 is installed on the first unwinding shaft 21 in the unwinding mechanism 2 and a spare material roll 7 is installed on the second unwinding shaft 22, in this case, when the working material roll 6 on the first unwinding shaft 21 is almost unwound, first, the clamping mechanism 3 can be used to clamp the working material tape 61, and then the cutting mechanism 4 can be used to cut the working material tape 61 clamped by the clamping mechanism 3, so that the working material roll 6 and the working material tape 61 are separated, facilitating the subsequent tape splicing operation. Since the spare material tape 71 is unwound from the spare material roll 7 on the second unwinding shaft 22, after the cutting of the working material tape 61 is completed, the splicing mechanism 5 is used to splice the spare material tape 71 clamped by the clamping mechanism 3 and the cut working material tape 61 clamped by the clamping mechanism 3 to realize the tape splicing of the spare material tape 71 and the working material tape 61 and complete the roll change.

[0074] After the roll change is completed, unwind the spare material roll 7 on the second unwinding shaft 22. At this time, as Figure 2 shown, the spare material roll 7 on the second unwinding shaft 22 becomes the working material roll 6, that is, at this time, the working material roll 6 is installed on the second unwinding shaft 22. Since the working material roll 6 on the first unwinding shaft 21 has been unwound, as Figure 2 shown, the spare material roll 7 can be installed on the first unwinding shaft 21 to perform roll change after the working material roll 6 on the second unwinding shaft 22 is unwound. The roll change process when the spare material roll 7 is installed on the first unwinding shaft 21 and the working material roll 6 is installed on the second unwinding shaft 22 is similar to the above roll change process and will not be repeated here.

[0075] Compared with the related art, in the present application, since the first unwinding shaft 21 and the second unwinding shaft 22 are arranged at intervals in the vertical direction, even if relatively large-diameter material rolls are installed on the first unwinding shaft 21 and the second unwinding shaft 22, each material roll has a relatively small occupied space in the horizontal direction, and further, the roll change device 100 also has a relatively small occupied space in the horizontal direction, which is beneficial to facilitating the arrangement of the roll change device 100 in the horizontal direction.

[0076] It should be explained that according to the above description, it can be seen that the first unwinding shaft 21 is not only used to install the working material roll 6, and the second unwinding shaft 22 is not only used to install the spare material roll 7. The first unwinding shaft 21 and the second unwinding shaft 22 can not only install the working material roll 6, but also install the spare material roll 7, and the types of material rolls installed on the first unwinding shaft 21 and the second unwinding shaft 22 are relatively flexible. In this embodiment, the case where the working material roll 6 is first installed on the first unwinding shaft 21 and the spare material roll 7 is first installed on the second unwinding shaft 22 is taken as an example for illustration.

[0077] Regarding the vertical arrangement between the first unwinding reel 21 and the second unwinding reel 22, it should be noted that the vertical arrangement of the first unwinding reel 21 and the second unwinding reel 22 can be set to be aligned in the vertical direction, or can be inclined in the vertical direction, that is, the first unwinding reel 21 and the second unwinding reel 22 are not aligned in the vertical direction. The vertical arrangement between the first unwinding reel 21 and the second unwinding reel 22 is relatively flexible. Specifically, it can be set according to actual usage requirements, and the embodiments of the present application do not make specific limitations on this.

[0078] Regarding the material clamping mechanism 3, further, as Figure 1 and Figure 2 shown, the material clamping mechanism 3 includes a first fixed material clamping component 31 and a movable material clamping component. Among them, the first fixed material clamping component 31 is fixedly arranged on the installation base 1 and is used for clamping the working material tape 61.

[0079] The movable material clamping component is movably arranged on the installation base 1 along the first direction (such as the Z direction in Figure 1 ) so that the movable material clamping component is docked with the first fixed material clamping component 31, and the movable material clamping component is used for clamping the working material tape 61 or the spare material tape 71.

[0080] The cutting mechanism 4 is used for cutting the working material tape 61 jointly clamped by the movable material clamping component and the first fixed material clamping component 31 when the two are docked, and the tape splicing mechanism 5 is used for splicing the cut working material tape 61 clamped by the first fixed material clamping component 31 and the spare material tape 71 clamped by the movable material clamping component when the first fixed material clamping component 31 and the movable material clamping component are docked.

[0081] With such a setting, when the working material roll 6 on the first unwinding reel 21 is normally unwound, the unwound working material tape 61 will pass through the movable material clamping component and the first fixed material clamping component 31; when the working material roll 6 on the first unwinding reel 21 is almost unwound, the movable material clamping component and the first fixed material clamping component 31 jointly clamp the working material tape 61, and the cutting mechanism 4 cuts the working material tape 61 clamped by the two.

[0082] After cutting is completed, the first fixed material clamping component 31 continues to clamp the cut working material tape 61. After the movable material clamping component moves in the first direction to be close to the second unwinding reel 22, it clamps the spare material tape 71 unwound from the spare material roll 7 on the second unwinding reel 22. After the movable material clamping component moves in the first direction to be docked with the first fixed material clamping component 31, the tape splicing mechanism 5 splices the cut working material tape 61 clamped by the first fixed material clamping component 31 and the spare material tape 71 clamped by the movable material clamping component to complete the roll change.

[0083] According to the above description, the moving and docking functions of the movable material clamping assembly can shorten the time required for the material clamping operation during the roll change process. Compared with the fixed and immovable material clamping mechanism, this design can improve production efficiency and reduce the downtime of the production line.

[0084] For the first direction, in the embodiments of the present application, the first direction can be a vertical direction, an inclined direction inclined along the vertical direction, or a horizontal direction. The setting of the first direction is relatively flexible. Specifically, it can be selected according to actual usage requirements, and the embodiments of the present application do not make specific limitations thereto. In this embodiment, the first direction is described by taking the vertical direction as an example.

[0085] In other embodiments, if the problem of production efficiency is not considered, the material clamping mechanism 3 can only include a fixed material clamping assembly. In this case, when splicing the working material tape 61 and the spare material tape 71, it is necessary to manually pull the spare material tape to the fixed material clamping assembly so that the fixed material clamping assembly can clamp the working material tape 61 and the spare material tape 71 at the same time. In this case, since the number of material clamping components in the material clamping mechanism 3 can be reduced, the manufacturing cost can be reduced to a certain extent.

[0086] Further, as Figure 1 and Figure 2 shown, there are two movable material clamping components, which are the first movable material clamping component 32 and the second movable material clamping component 33 respectively, and the first movable material clamping component 32 and the second movable material clamping component 33 are used to alternately dock with the first fixed material clamping component 31.

[0087] The first movable material clamping component 32 is used to clamp the working material tape 61 unrolled from the working material roll 6 on the first unwinding shaft 21 or the spare material tape 71 unrolled from the spare material roll 7; the second movable material clamping component 33 is used to clamp the working material tape 61 unrolled from the working material roll 6 on the second unwinding shaft 22 or the spare material tape 71 unrolled from the spare material roll 7.

[0088] With such a setting, as Figure 1 shown, the working material tape 61 unrolled from the working material roll 6 on the first unwinding shaft 21 will sequentially pass through the docked first movable material clamping component 32 and the first fixed material clamping component 31. When the working material roll 6 is almost completely unrolled, the first movable material clamping component 32 and the first fixed material clamping component 31 jointly clamp the working material tape 61, and the cutting mechanism 4 cuts the working material tape 61 clamped by both of them.

[0089] After cutting, the first fixed material clamping component 31 continues to clamp the cut working material tape 61. As Figure 2 shown, the first movable material clamping component 32 moves along the first direction to the first side of the first fixed material clamping component 31 so that the first movable material clamping component 32 is not docked with the first fixed material clamping component 31. At the same time, as Figure 1 andFigure 2 As shown, the second movable material clamping component 33 clamps the spare material tape 71 unrolled from the spare material roll 7 on the second material unrolling shaft 22, and moves in the first direction from the second side of the first fixed material clamping component 31 to dock with the first fixed material clamping component 31. After docking, the tape splicing mechanism 5 splices the cut working material tape 61 clamped by the first fixed material clamping component 31 and the spare material tape 71 clamped by the second movable material clamping component 33 to complete the roll change.

[0090] After the roll change is completed, as Figure 2 shown, since the spare material roll 7 unrolled on the second material unrolling shaft 22 becomes the working material roll 6, when the working material roll 6 on the second material unrolling shaft 22 is almost unrolled, the second movable material clamping component 33 and the first fixed material clamping component 31 can jointly clamp the working material tape 61 unrolled from the working material roll 6 on the second material unrolling shaft 22. After the working material roll 6 on the first material unrolling shaft 21 is unrolled, since a spare material roll 7 can be installed on the first material unrolling shaft 21, the first movable material clamping component 32 on the first side can clamp the spare material tape 71 unrolled from the spare material roll 7 on the first material unrolling shaft 21, so as to clamp the spare material tape 71 and dock with the first fixed material clamping component 31 for roll change after the working material roll 6 on the second material unrolling shaft 22 is unrolled.

[0091] According to the above description, through the moving and docking functions of the first movable material clamping component 32 and the second movable material clamping component 33, the time required for the material clamping operation during the roll change can be further shortened, thereby further improving the production efficiency and further reducing the downtime of the production line.

[0092] In other embodiments, if the problem of further improving the production efficiency is not considered, only one movable material clamping component can be provided. In this case, the movable material clamping component can clamp either the working material tape 61 or the spare material tape 71 unrolled from the material roll on the first material unrolling shaft 21, or the working material tape 61 or the spare material tape 71 unrolled from the material roll on the second material unrolling shaft 22. With such a setting, since the number of movable material clamping components can be reduced, the manufacturing cost can be reduced.

[0093] Furthermore, as Figure 1 and Figure 2 shown, the cutting mechanism 4 includes a first cutting component 41, and the first cutting component 41 is used to cut the working material tape 61 jointly clamped by the first fixed material clamping component 31 and the first movable material clamping component 32 or the first fixed material clamping component 31 and the second movable material clamping component 33.

[0094] The cutting mechanism 4 further includes a second cutting assembly 42, which is located on the first side of the first fixed material clamping assembly 31 in the first direction. The second cutting assembly 42 is used to cut the spare tape 71 clamped by the first movable material clamping assembly 32 when the first movable material clamping assembly 32 is located on the first side; and / or, the cutting mechanism 4 further includes a third cutting assembly 43, which is located on the second side of the first fixed material clamping assembly 31 in the first direction. The third cutting assembly 43 is used to cut the spare tape 71 clamped by the second movable material clamping assembly 33 when the second movable material clamping assembly 33 is located on the second side.

[0095] With such a setting, on the one hand, through the coordinated work of the first cutting assembly 41 and the second cutting assembly 42 and / or the first cutting assembly 41 and the third cutting assembly 43, cutting operations can be carried out simultaneously or sequentially in different working stages, greatly shortening the time required for cutting the tape during the roll change process and improving the roll change efficiency; on the other hand, by cutting the working tape 61 and the spare tape 71, it is beneficial to provide a good basis for the subsequent tape splicing operation and improve the splicing quality.

[0096] In a preferred embodiment, the cutting mechanism 4 further includes a second cutting assembly 42 and a third cutting assembly 43. With such a setting, on the one hand, through the coordinated work of the first cutting assembly 41, the second cutting assembly 42 and the third cutting assembly 43, it is beneficial to further improve the roll change efficiency; on the other hand, since the second cutting assembly 42 can cut the spare tape 71 clamped by the first movable material clamping assembly 32, and since the third cutting assembly 43 can also cut the spare tape 71 clamped by the second movable material clamping assembly 33, it is beneficial to further improve the splicing quality.

[0097] In this embodiment, the structures of the first cutting assembly 41, the second cutting assembly 42 and the third cutting assembly 43 are the same. The structure of the first cutting assembly 41 is taken as an example for description in this embodiment.

[0098] Specifically, as Figure 3 shown, the first cutting assembly 41 includes a first cutting driving member 411, a first connecting plate 412, a first guiding rod 413, a first guiding cylinder 414 and a first cutting knife 415. Among them, the first guiding cylinder 414 is fixed to the mounting base 1. The first guiding rod 413 is guidingly inserted into the first guiding cylinder 414 and is connected to the first connecting plate 412. The telescopic shaft of the first cutting driving member 411 is connected to the connecting plate 412. In this way, the first cutting driving member 411 can drive the first cutting knife 415 provided on the first connecting plate 412 to act by driving the first connecting plate 412 to move, realizing the cutting of the tape. At the same time, through the guiding cooperation between the first guiding rod 413 and the first guiding cylinder 414, the movement of the first cutting knife 415 can be made more stable, and thus the cutting quality of the tape can be ensured.

[0099] For the first cutting driving member 411, in the embodiments of the present application, the first cutting driving member 411 can be any one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder. The type selection of the first cutting driving member 411 is relatively flexible, and the embodiments of the present application do not make specific limitations on this.

[0100] Further, as Figure 2 shown, the second cutting assembly 42 includes a second cutting blade 421, and the first cutting blade 415 and the second cutting blade 421 are arranged in alignment in the first direction; and / or, the third cutting assembly 43 includes a third cutting blade 431, and the first cutting blade 415 and the third cutting blade 431 are arranged in alignment in the first direction.

[0101] When the first cutting blade 415 and the second cutting blade 421 (or the third cutting blade 431) are arranged in alignment in the first direction, it can ensure that the cutting positions of the working strip 61 and the spare strip 71 are aligned in the first direction. When splicing the working strip 61 and the spare strip 71, if the cutting positions are not aligned, problems such as wrinkles, gaps, or reduced strength may occur in the spliced strip, affecting the product quality. And the alignment setting of the cutting blades can minimize this error to the greatest extent, improve the alignment degree of the cutting positions in the first direction, and thus ensure the smooth progress of the subsequent tape connecting operation and the stable quality of the product.

[0102] In a preferred embodiment, as Figure 2 shown, the first cutting blade 415, the second cutting blade 421, and the third cutting blade 431 are all arranged in alignment in the first direction. With such a setting, it can further ensure the smooth progress of the subsequent tape connecting operation and the stable quality of the product.

[0103] For the material clamping mechanism 3, further, as Figure 1 and Figure 2 shown, the material clamping mechanism 3 further includes a second fixed material clamping assembly 34. The second fixed material clamping assembly 34 is located on the above-mentioned first side and is used to jointly clamp the spare strip 71 with the first movable material clamping assembly 32 when docking with the first movable material clamping assembly 32. The second cutting assembly 42 is used to cut the spare strip 71 jointly clamped by the second fixed material clamping assembly 34 and the first movable material clamping assembly 32. And / or, the material clamping mechanism 3 further includes a third fixed material clamping assembly 35. The third fixed material clamping assembly 35 is located on the above-mentioned second side and is used to jointly clamp the spare strip 71 with the second movable material clamping assembly 33 when docking with the second movable material clamping assembly 33. The third cutting assembly 43 is used to cut the spare strip 71 jointly clamped by the third fixed material clamping assembly 35 and the second movable material clamping assembly 33.

[0104] With such a setting, the spare tape 71 is jointly clamped by the second fixed clamping component 34 and the first movable clamping component 32 and / or the third fixed clamping component 35 and the second movable clamping component 33. In this way, when cutting the spare tape 71, the stability of the spare tape 71 can be ensured, and thus the cutting quality can be guaranteed.

[0105] In a preferred embodiment, as Figure 1 and Figure 2 shown, the clamping mechanism 3 further includes a second fixed clamping component 34 and a third fixed clamping component 35. With such a setting, since the spare tape 71 can be jointly clamped not only by the second fixed clamping component 34 and the first movable clamping component 32, but also by the third fixed clamping component 35 and the second movable clamping component 33, the stability of the spare tape 71 unrolled from the reels on both the first unwinding shaft 21 and the second unwinding shaft 22 can be ensured, and thus the cutting quality of the spare tape 71 unrolled from the reels on both the first unwinding shaft 21 and the second unwinding shaft 22 can be guaranteed.

[0106] In this embodiment, the structures of the first fixed clamping component 31, the first movable clamping component 32, the second movable clamping component 33, the second fixed clamping component 34 and the third fixed clamping component 35 are all the same. The structure of the first fixed clamping component 31 is taken as an example for illustration in this embodiment.

[0107] Specifically, as Figure 4 shown, the first fixed clamping component 31 includes a first support 311, a first pressing plate 312 and a first clamping driving part 313. Among them, the first clamping driving part 313 is arranged on the first support 311, and the telescopic shaft of the first clamping driving part 313 is connected to the first pressing plate 312. In this way, the first clamping driving part 313 can drive the first pressing plate 312 to approach or move away from the first support 311 to clamp or release the tape. With such a setting, not only can the first clamping driving part 313 drive the first pressing plate 312 to act to reliably clamp the tape, but also to a certain extent, the structure of the first fixed clamping component 31 can be simplified, which is beneficial to the manufacture of the first fixed clamping component 31.

[0108] For the first clamping driving part 313, in the embodiment of the present application, the first clamping driving part 313 can be any one of an electric cylinder, a pneumatic cylinder and a hydraulic cylinder. The type selection of the first clamping driving part 313 is relatively flexible, and the embodiment of the present application does not make specific limitations on this.

[0109] For the clamping mechanism 3, further, as Figure 1 and Figure 2As shown, the material clamping mechanism 3 further includes a first waste collecting shaft 36 located on the first side. The first waste collecting shaft 36 is used for winding up the spare tape 71 cut off by the second cutting assembly 42. And / or, the material clamping mechanism 3 further includes a second waste collecting shaft 37 located on the second side. The second waste collecting shaft 37 is used for winding up the spare tape 71 cut off by the third cutting assembly 43.

[0110] With such a setting, on the one hand, the cut waste materials can be collected orderly, avoiding the interference of waste material accumulation on production operations. The operator does not need to clean the waste materials frequently, so that more energy can be devoted to the production process, improving the overall production efficiency. On the other hand, the collected waste materials can be reused, which is conducive to reducing costs.

[0111] In a preferred embodiment, the material clamping mechanism 3 further includes a first waste collecting shaft 36 and a second waste collecting shaft 37. With such a setting, through the first waste collecting shaft 36 and the second waste collecting shaft 37, it is not only beneficial to further improve the production efficiency, but also beneficial to further reduce costs.

[0112] For the material clamping mechanism 3, further, as Figure 1 shown, the material clamping mechanism 3 further includes a driving assembly 38. The driving assembly 38 is used to drive the first movable material clamping assembly 32 and the second movable material clamping assembly 33 to move along the first direction, so that the first movable material clamping assembly 32 and the second movable material clamping assembly 33 are alternately docked with the first fixed material clamping assembly 31.

[0113] With such a setting, by quickly driving the movable material clamping assembly by the driving assembly 38, the switching time of the movable material clamping assembly during the roll change process can be shortened, and the roll change efficiency can be improved.

[0114] For the driving assembly 38, in one embodiment, the driving assembly 38 is used to drive the first movable material clamping assembly 32 and the second movable material clamping assembly 33 to move synchronously along the first direction.

[0115] When driving the first movable material clamping assembly 32 and the second movable material clamping assembly 33 to move synchronously along the first direction, their speeds and displacements during the movement always remain the same. This enables the two movable material clamping assemblies to maintain a high degree of coordination and synchronization when docking with the first fixed material clamping assembly 31 or performing other operations, avoiding operation errors or deviations caused by non-synchronization.

[0116] Further, the driving assembly 38 includes a set of lead screw nut mechanism, and as Figure 1As shown, both the first movable material clamping component 32 and the second movable material clamping component 33 are in threaded engagement with a lead screw 381 in the lead screw nut mechanism. Thus, when the lead screw 381 rotates, through the threaded engagement between the lead screw 381 and the first movable material clamping component 32 and the second movable material clamping component 33, the first movable material clamping component 32 and the second movable material clamping component 33 can be driven to move synchronously in the first direction.

[0117] With such a setting, on the one hand, since the lead screw nut mechanism has high motion accuracy, the moving distance and position of the first movable material clamping component 32 and the second movable material clamping component 33 in the first direction can be precisely adjusted through the lead screw nut mechanism. On the other hand, since both the first movable material clamping component 32 and the second movable material clamping component 33 are in threaded engagement with the same lead screw 381, when the lead screw 381 rotates, the two movable material clamping components will move synchronously under the drive of the lead screw 381, thereby ensuring the synchronism of the two movable material clamping components during the movement process.

[0118] For the drive component 38, in another embodiment, the drive component 38 is used to drive the first movable material clamping component 32 and the second movable material clamping component 33 to move in the first direction respectively.

[0119] With such a setting, on the one hand, according to different production requirements and actual situations, the position of each movable material clamping component can be adjusted separately and the operation can be controlled, which can increase the flexibility of driving the first movable material clamping component 32 and the second movable material clamping component 33. On the other hand, if one of the movable material clamping components fails or needs to be maintained, since they can move separately, the problematic component can be moved separately to a position convenient for maintenance without affecting the normal operation of the other component.

[0120] Furthermore, the drive component 38 includes two sets of lead screw nut mechanisms, and as Figure 5 shown, the first movable material clamping component 32 and the second movable material clamping component 33 are respectively in threaded engagement with two lead screws 381 in the two sets of lead screw nut mechanisms. Thus, when the two lead screws 381 rotate, through the threaded engagement between the first movable material clamping component 32 and the second movable material clamping component 33 and the corresponding lead screws 381 respectively, the first movable material clamping component 32 and the second movable material clamping component 33 can be driven to move in the first direction respectively.

[0121] With such a setting, since the lead screw nut mechanism has high motion accuracy, through the threaded engagement between the first movable material clamping component 32 and the second movable material clamping component 33 and different lead screws 381 respectively, not only can the separate movement of the two movable material clamping components in the first direction be ensured, but also the moving distance and position of the two movable material clamping components in the first direction can be precisely adjusted.

[0122] As Figure 1 andFigure 2 As shown, the first movable tape clamping assembly 32 includes a second support, and the second movable tape clamping assembly 33 includes a third support. Both the second support and the third support have a tape clamping plane for clamping the tape and contacting the tape. The rewinding device 100 further includes a first guide roller 8 and a second guide roller 9. Among them, the first guide roller 8 is connected to the first movable tape clamping assembly 32 and can move along the first direction with the first movable tape clamping assembly 32. The uppermost edge of the first guide roller 8 is flush with the tape clamping plane of the second support. The second guide roller 9 is connected to the second movable tape clamping assembly 33 and can move along the first direction with the second movable tape clamping assembly 33. The lowermost edge of the second guide roller 9 is flush with the tape clamping plane of the third support.

[0123] With such a setting, on the one hand, since the first guide roller 8 and the second guide roller 9 are respectively connected to the first movable tape clamping assembly 32 and the second movable tape clamping assembly 33, the guide rollers can move with the movement of the movable tape clamping assemblies. In this way, during the movement of the movable tape clamping assemblies, the guide rollers can always support and guide the tape, enabling the tape to be stably transported along a predetermined path. On the other hand, since the uppermost edge of the first guide roller 8 is flush with the tape clamping plane of the second support, and the lowermost edge of the second guide roller 9 is flush with the tape clamping plane of the third support, this enables the tape to be better positioned and guided when entering the tape clamping plane. In this way, the guide rollers can help the tape accurately enter the tape clamping area, ensuring that the tape clamping plane can tightly clamp the tape, improving the accuracy and reliability of tape clamping.

[0124] For the tape splicing mechanism 5, further, as Figure 2 shown, the tape splicing mechanism 5 includes a glue preparation assembly 51 and a glue pasting assembly 52. The glue preparation assembly 51 is used to provide tape to the glue pasting assembly 52, and the glue pasting assembly 52 is used to paste the tape between the spare tape 71 and the cut working tape 61 to splice the spare tape 71 and the cut working tape 61.

[0125] The setting of the glue preparation assembly 51 and the glue pasting assembly 52 enables the glue preparation and glue pasting operations during the tape splicing process to be carried out simultaneously or sequentially in an orderly manner. On the one hand, the glue pasting assembly 52 can be used to complete the splicing of the spare tape 71 and the working tape 61. On the other hand, the glue preparation assembly 51 can continuously provide tape to the glue pasting assembly 52, ensuring that the glue pasting operation will not be interrupted due to waiting for tape. This fast material supply and operation connection make the entire tape splicing process smoother and reduce the time delay caused by untimely material supply.

[0126] Further, the mounting base 1 has a tape splicing position, and the glue pasting assembly 52 is used to paste the tape between the spare tape 71 located at the tape splicing position and the cut working tape 61. As Figure 2As shown, the glue preparation component 51 and the tape connection position are arranged at intervals in the vertical direction, and the glue application component 52 is located between the glue preparation component 51 and the tape connection position in the vertical direction.

[0127] The vertical arrangement of the glue preparation component 51, the glue application component 52 and the tape connection position can make full use of the vertical space and avoid occupying too much space in the horizontal direction. At the same time, the tape can pass through the glue preparation component 51 and the glue application component 52 from top to bottom to reach the tape connection position, which is in line with the direction of gravity and is conducive to making the transfer and pasting process of the tape smoother.

[0128] Furthermore, if Figure 6 As shown, the glue sticking component 52 includes a rotating driving component 521, a rotating shaft 522 and a glue sticking component 523. The central axis of the rotating shaft 522 extends laterally. The glue sticking component 523 is connected to the rotating shaft 522. The rotating driving component 521 is used to drive the rotating shaft 522 to rotate around the central axis to drive the glue sticking component 523 to swing up and down, so that the glue sticking component 523 is directed toward the standby glue component 51 or the above-mentioned tape connection position. The glue sticking component 523 is used to pick up the tape provided by the standby glue component 51 when it is directed toward the standby glue component 51. The glue sticking component 523 is used to provide the tape to be pasted between the standby material tape 71 and the cut working material tape 61 when it is directed toward the tape connection position.

[0129] The rotating drive member 521 drives the rotating shaft 522 to rotate, which helps the glue sticking member 523 to quickly swing up and down and switch between the glue preparation component 51 and the tape connection position, which helps to shorten the time interval from glue taking to glue sticking and reduce the time cost of the entire tape connection operation.

[0130] Furthermore, if Figure 6 As shown, the rotating driving member 521 and the rotating shaft 522 are connected to each other through a transmission structure 524, and the transmission structure 524 includes a first pulley 5241, a second pulley 5242 and a belt 5243. The first pulley 5241 is connected to the output end of the rotating driving member 521, and the second pulley 5242 is coaxially connected to the rotating shaft 522. The belt 5243 is sleeved on the outer sides of the first pulley 5241 and the second pulley 5242.

[0131] With such arrangement, when the rotary driving member 521 drives the first pulley 5241 to rotate, the first pulley 5241 can drive the second pulley 5242 to rotate through the transmission of the belt 5243 , and then the second pulley 5242 can drive the rotating shaft 522 to rotate.

[0132] On the one hand, since the belt 5243 has a certain elasticity, when encountering external interference or a change in the rotational speed of the rotational driving member 521, the elasticity of the belt 5243 can play a buffering role, avoiding excessive impact on the rotating shaft 522 and the rubber pasting member 523, and ensuring the stability of the tape joining operation. On the other hand, the noise and vibration generated by belt drive are relatively small, which can not only reduce noise but also reduce the impact of vibration on other components.

[0133] For the rubber pasting assembly 52, further, as Figure 6 shown, the rubber pasting assembly 52 further includes a lifting driving member 525. The lifting driving member 525 is in transmission connection with the rotational driving member 521. The lifting driving member 525 is used to drive the rotational driving member 521 and the rotating shaft 522 to drive the rubber pasting member 523 to move vertically.

[0134] In actual production, different tape joining positions or tapes of different specifications may be encountered. By driving the rubber pasting member 523 to move vertically through the lifting driving member 525, the position of the rubber pasting member 523 can be flexibly adapted to these changes, and the vertical position can be adjusted according to specific situations, improving the versatility and adaptability of the rewinding device 100.

[0135] Further, as Figure 6 shown, the rubber pasting assembly 52 further includes a lateral driving member 526. The lateral driving member 526 is in transmission connection with the output end of the lifting driving member 525. The output end of the lateral driving member 526 is in transmission connection with the rotational driving member 521, so that the lifting driving member 525 is indirectly in transmission connection with the rotational driving member 521. The lateral driving member 526 is used to drive the rubber pasting member 523 to reciprocally move in a first lateral direction (such as the X direction in Figure 6 ) perpendicular to the extending direction of the above-mentioned central axis through the rotational driving member 521 and the rotating shaft 522.

[0136] With such a setting, on the one hand, the presence of the lateral driving member 526 enables the rubber pasting member 523 to not only move vertically and swing around the rotating shaft 522 but also reciprocally move in the first lateral direction. This multi-dimensional position adjustment ability greatly improves the adaptability of the rubber pasting assembly 52 in different working scenarios. On the other hand, in actual production, various complex tape joining situations may be encountered, such as position deviation of the tape, irregularity of the tape joining position, etc. The lateral driving member 526 can flexibly adjust the lateral position of the rubber pasting member 523 according to these actual situations, enabling the rubber pasting operation to proceed smoothly.

[0137] For the rubber pasting assembly 52, in a preferred embodiment, as Figure 6As shown, a first support base 527 is connected to the output end of the lifting drive member 525. The first support base 527 is connected to a second support base 528. The lateral drive member 526 is disposed on the second support base 528, and a third support base 529 is slidably mounted on the second support base 528. The rotary drive member 521 is disposed on the third support base 529. The lateral drive member 526 drives the third support base 529 to move along the first lateral direction, thereby driving the rotary drive member 521, the rotary shaft 522, and the glue-applying member 523 to move along the first lateral direction.

[0138] The first support base 527, the second support base 528, and the third support base 529 together constitute a multi-layer support base. This design of the multi-layer support base can provide a stable installation foundation for each drive member, which is beneficial to the stable installation of each drive member in the glue-applying assembly 52, and further beneficial to ensuring the stable operation of the glue-applying assembly 52.

[0139] For the glue preparation assembly 51, the structural arrangement of the glue preparation assembly 51 is relatively flexible, and the embodiments of the present application do not make specific limitations thereto.

[0140] In the embodiments of the present application, any one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder can be used for the rotary drive member 521, the lifting drive member 525, and the lateral drive member 526. The type selection of the above three is relatively flexible, and the embodiments of the present application do not make specific limitations thereto.

[0141] Embodiment Two

[0142] The present application also provides a winding device, as Figure 7 shown. The winding device includes a roll-changing device 100. The roll-changing device 100 has the same structure as any one of the roll-changing devices 100 in the above embodiments and can bring the same or similar beneficial effects. For details, reference can be made to the descriptions in the above embodiments, and the details are not repeated herein.

[0143] Compared with the related art, in the present application, since the first unwinding shaft 21 and the second unwinding shaft 22 are arranged at intervals in the vertical direction, even if relatively large-diameter coils are installed on the first unwinding shaft 21 and the second unwinding shaft 22, the coils also have relatively small occupied space in the horizontal direction. As a result, the roll-changing device 100 also has relatively small occupied space in the horizontal direction, which is beneficial to facilitating the arrangement of the roll-changing device 100 in the horizontal direction.

[0144] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
