Description

Technical Field

[0001] This application relates to the field of winding and unwinding devices, and more specifically, to an integrated winding and unwinding device and a composite current collector production system. Background Technology

[0002] In traditional technologies, for production systems requiring simultaneous unwinding and winding processes, the unwinding and winding subsystems are typically arranged separately on the production line, mounted on the installation ground via corresponding supports; that is, the winding and unwinding sides are set up in separate horizontally separated frames. Although traditional technologies mention integrated unwinding and winding devices, these devices still essentially arrange the winding and unwinding mechanisms at different horizontal positions on the installation ground via different support supports. In scenarios with limited space, especially when horizontal space is limited, the existing separate arrangement structure is difficult to deploy accordingly. Moreover, in such scenarios with limited space, even if integrated unwinding and winding is achieved, it is difficult to implement complex tension control on the integrated unwinding and winding device while saving space, especially on the winding side and other structural sides where substrate stretching is required.

[0003] Therefore, the industry urgently needs an integrated device that can combine unwinding and winding, suitable for scenarios with limited horizontal space, and easy to achieve the required tension control. Utility Model Content

[0004] Based on this, this application provides an integrated winding and unwinding device, which integrates winding and unwinding operations, makes full use of longitudinal space, facilitates tension control within a limited operating space, and is simple to operate.

[0005] The technical solution adopted in this application is an integrated unwinding and winding device, comprising: an unwinding column, a winding column, a guide roller, an adaptive mechanism, and a main support. The unwinding column, guide roller, winding column, and adaptive mechanism are all arranged on the main support. The winding column is positioned above the unwinding column, and the guide roller is positioned between the unwinding column and the winding column. The adaptive mechanism includes a proximity pressure roller and an adjustment mechanism. The proximity pressure roller is positioned on the adjustment mechanism and is adjacent to the winding column. The adjustment mechanism is used to adaptively adjust the distance between the proximity pressure roller and the outer surface of the winding column. The substrate to be wound or unwound travels along a path formed in sequence by the unwinding column, guide roller, proximity pressure roller, and winding column.

[0006] The integrated unwinding and take-up device described in this application concentrates on the less utilized longitudinal space, achieving integrated unwinding and take-up while simultaneously ensuring an adaptive tension adjustment method. Specifically, this integrated unwinding and take-up device makes full use of the longitudinal space, integrating an unwinding column, a take-up column, and an adaptive mechanism within a limited longitudinal space. The unwinding column, the guide roller, the take-up column, and the adaptive mechanism are all arranged on the main support. During operation, the unwinding column releases the substrate, which passes through at least the roller and the pressure roller before reaching the take-up column. Simultaneously, as the take-up column is running, the adaptive mechanism adaptively adjusts the distance between the pressure roller and the outer surface of the take-up column to maintain a preset distance, thereby adjusting the corresponding lateral tension. This allows the take-up column to smoothly and neatly wind up the substrate, resulting in a tight, neat, and flat rear end face. In addition, this integrated unwinding and take-up device has a stable structure, is easy to operate, and is convenient for installation, arrangement, and maintenance.

[0007] In one embodiment, the number of rollers is two or more.

[0008] In one embodiment, the adjustment mechanism includes a first drive mechanism and a second drive mechanism. The first drive mechanism drives the second drive mechanism to move closer to or away from the take-up column on the first drive mechanism. The end of the approach pressure roller is mounted on the second drive mechanism, and the second drive mechanism drives the approach pressure roller to move closer to or away from the take-up column on the second drive mechanism.

[0009] The first and second drive mechanisms of this application can be used individually or in combination to adaptively adjust the distance between the proximity pressure roller and the outer surface of the take-up column, thereby adjusting the corresponding lateral tension. Specifically, when the thickness of the take-up column changes, the distance between the proximity pressure roller and the outer surface of the take-up column changes. The first drive mechanism can be used alone, the second drive mechanism can be used alone, or the first and second drive mechanisms can be used in combination to move the proximity pressure roller, so that the proximity pressure roller and the outer surface of the take-up column can be precisely maintained at a stable preset distance or preset distance range (understandably, when an allowable error exists, the preset distance range is the preset distance ± error), controlling the tension of the roll material on one side of the take-up column. Furthermore, the first and second drive mechanisms can be arranged in a narrow space to achieve a common total stroke greater than the stroke of either the first or second drive mechanism.

[0010] In one embodiment, the first drive mechanism and the second drive mechanism near both sides of the pressure roller are symmetrically arranged, which is more conducive to adjusting the tension of the substrate during the winding and unwinding process.

[0011] In one embodiment, the first driving mechanism includes a first power mechanism, a transfer base plate, and a first slide rail. The output end of the first power mechanism is connected to a gear. The transfer base plate is mounted on the first slide rail, and a rack is fixed on the transfer base plate. The gear, in conjunction with the rack, drives the transfer base plate to move on the first slide rail.

[0012] In one embodiment, the second driving mechanism includes a second power mechanism, a base slider, and a second slide rail. The second power mechanism and the second slide rail are both arranged on the transfer base plate. The second power mechanism drives the base slider to move on the second slide rail. The end of the proximity roller is mounted on the base slider.

[0013] The first power mechanism drives the gear to rotate, which in turn engages with the rack on the transfer base plate to move the transfer base plate along the first slide rail. Simultaneously, the second power mechanism and the second slide rail in the second drive mechanism are both arranged on the transfer base plate, and the base slider connected to the end of the pressure roller is arranged on the second slide rail. In other words, the entire second drive mechanism is mounted on the transfer base plate. When the first power mechanism drives the transfer base plate to move, the second drive mechanism on the transfer base plate moves synchronously. That is, the first drive mechanism can drive the second drive mechanism to move, and thus drive the pressure roller connected to the second drive mechanism; the second drive mechanism on the transfer base plate can also independently drive the pressure roller. In other words, relatively independent pressure roller driving can be achieved through the first and second drive mechanisms. Alternatively, the first and second drive mechanisms can cooperate to move in the same or opposite directions, realizing a complex pressure roller adjustment process.

[0014] In one embodiment, the adaptive mechanism further includes a transfer roller arranged adjacent to the approach pressure roller along a direction away from the take-up column. When the first drive mechanism drives the second drive mechanism to move, the transfer roller is moved synchronously with the second drive mechanism, further improving the accuracy and effectiveness of tension adjustment.

[0015] In one embodiment, the adaptive mechanism further includes a detection unit for detecting the distance between the proximity roller and the outer surface of the winding column, or for detecting the tension of the substrate to be wound on the winding column during the winding process.

[0016] In one embodiment, the take-up and unwind integrated device further includes a traction mechanism for guiding the substrate to the take-up column; the traction mechanism includes a drive roller, a traction rubber roller, and an arrangement wall panel; wherein the arrangement wall panel is detachably mounted on the main support, and the drive roller and the traction rubber roller are both mounted on the arrangement wall panel, the drive roller and the traction rubber roller cooperate to clamp the substrate, when the drive roller is driven to move the substrate, the traction rubber roller keeps the surface of the substrate in contact with the surface of the drive roller, so that the substrate is pulled out.

[0017] In one embodiment, the main support includes a base, a first correction mechanism, two main wall panels, an upper base plate, and a second correction mechanism. The first correction mechanism is disposed on the base, the main wall panels are disposed on the first correction mechanism, the upper base plate is disposed above the main wall panels, and the second correction mechanism is disposed on the upper base plate. The unwinding column and the guide roller are both installed between the two main wall panels, and the winding column and the adaptive mechanism are installed on the second correction mechanism. The first correction mechanism corrects the unwinding offset of the unwinding column relative to the downstream conveying mechanism by moving the main wall panels along the length direction of the unwinding column. The second correction mechanism corrects the positional offset of the unwinding column relative to the unwound substrate by moving the winding column relative to the main wall panels along the length direction of the winding column.

[0018] In one embodiment, the first correction mechanism includes a first guide component and a lower base plate. The first guide component is installed between the base and the lower base plate, and the main wall plate is installed on the lower base plate. The lower base plate is driven to move the main wall plate relative to the base on the first guide component.

[0019] In one embodiment, a plurality of the first guide components are arranged in an array between the lower base plate and the base. The array arrangement of multiple first guide components improves guiding accuracy, and the multiple positions restrict the guiding direction, overcoming guiding deviations that may be caused by component errors. Furthermore, it enhances the supporting effect of the first guide components on the upper structure, thereby strengthening the overall structural stability.

[0020] In one embodiment, the second correction mechanism includes a second guide component and a top plate. The second guide component is installed between the upper bottom plate and the top plate, and the winding column and the adaptive mechanism are both installed on the top plate. The top plate is driven to move the winding column and the adaptive mechanism relative to the upper bottom plate on the second guide component.

[0021] In one embodiment, a plurality of second guide components are arrayed between the top plate and the upper bottom plate. The arrayed distribution of multiple second guide components improves guiding accuracy, limits the guiding direction at multiple positions, overcomes guiding deviations that may be caused by component errors, and enhances the supporting effect of the second guide components on the upper structure, thereby strengthening the overall structural stability.

[0022] In one embodiment, the integrated take-up and unwinding device further includes a floating roller device, which comprises a floating roller mounting main board, a floating roller drive mechanism, a floating roller body, and a counterweight assembly. The floating roller mounting main board is rotatably mounted on the main wall plate, and the floating roller drive mechanism drives the floating roller mounting main board to rotate. The end of the floating roller body is mounted on one side of the rotation center of the floating roller mounting main board, and the counterweight assembly is located on the other side of the rotation center of the floating roller mounting main board. The floating roller drive mechanism drives the floating roller mounting main board to rotate, thereby causing the floating roller body to swing around the rotation center as a swing reference point to adjust the tension. The counterweight assembly facilitates counterweight balance based on the weight of the floating roller body, avoiding the accuracy impact caused by the weight of the floating roller body. Through the balance of the counterweight assembly, the driving degree of the floating roller drive mechanism can be precisely matched with the tension adjustment degree, thereby improving the adjustment accuracy of the floating roller device.

[0023] Another object of this application is to provide a composite current collector production system, including the integrated take-up and unwinding device described above. It will be understood that this composite current collector production system also possesses the advantages of the integrated take-up and unwinding device described above.

[0024] This application has at least the following beneficial effects: The integrated unwinding and take-up device described in this application makes full use of longitudinal space to achieve integrated unwinding and take-up, and can arrange unwinding and take-up simultaneously. It is suitable for scenarios with limited or narrow production line space and occupies little space. Furthermore, it is equipped with an adaptive mechanism that can adaptively adjust the distance between the proximity pressure roller and the take-up column, quickly and accurately achieving tension adjustment on the take-up column side within a limited length or space. This overcomes problems such as limited total stroke and difficulty in arrangement in a limited horizontal space, and facilitates the formation of an independent adjustment process for the proximity pressure roller through tension isolation. By continuously maintaining a preset distance, the tension adjustment process is simplified. In addition, the components required by this integrated unwinding and take-up device have simple structures, making them easy to assemble, manufacture, arrange, and maintain.

Detailed Implementation

[0050] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this application. This application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application. For better illustration of the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product; it will be understood by those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0051] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application and in its specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0052] In this application, "and / or" includes any and all combinations of one or more of the associated listed items. The terms "comprising," "having," and "including" as used in this application are intended to cover non-exclusive inclusion, unless explicit qualifying terms such as "only," "consisting of," etc., are used, in which case another component may be added.

[0053] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc. Similarly, "at least one" refers to one or more, including one, two, or more than two, and "multiple" refers to two or more, including two, three, or more than three, unless otherwise explicitly specified.

[0054] In this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0057] In this application, it should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element present. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0058] See Figures 1-24One embodiment of this application provides a winding and unwinding integrated device 1000, including: an unwinding column 1200, a winding column 1300, a guide roller 1400, an adaptive mechanism 100, and a main support 1100. The unwinding column 1200, the guide roller 1400, the winding column, and the adaptive mechanism 100 are all arranged on the main support 1100; the winding column 1300 is disposed above the unwinding column 1200, and the guide roller 1400 is disposed between the unwinding column 1200 and the winding column 1300. The adaptive mechanism 100 includes a proximity pressure roller 110 and an adjustment mechanism (shown in the figure but not marked). The proximity pressure roller 110 is disposed on the adjustment mechanism and is adjacent to the winding column 1300. The adjustment mechanism is used to adaptively adjust the distance between the proximity pressure roller 110 and the outer surface of the winding column 1300. The substrate to be wound or unwound travels on at least the path formed in sequence by the unwinding column 1200, the overpass roller 1400, the proximity pressure roller 110, and the winding column 1300.

[0059] Understandably, the substrate in this application includes flexible substrates such as film rolls. The unwinding column 1200 includes an unwinding shaft. Further, when the unwinding shaft is covered with a substrate, the unwinding column 1200 is formed by the unwinding shaft and its outer substrate; when the unwinding shaft has no outer substrate, the unwinding column 1200 is simply the unwinding shaft. Similarly, the winding column 1300 includes a winding shaft. Further, when the winding shaft is covered with a substrate, the winding column 1300 is formed by the winding shaft and its outer substrate; when the winding shaft has no outer substrate, the winding column 1300 is simply the winding shaft.

[0060] In this application, when the thickness of the take-up column 1300 changes, the approach pressure roller 110 is moved by the adjustment mechanism, so that the approach pressure roller 110 and the outer surface of the take-up column 1300 can maintain a stable preset distance or preset distance range (when an allowable error exists, the preset distance range is the preset distance ± error distance), thereby controlling the substrate tension on one side of the take-up column 1300.

[0061] For example, when space constraints prevent the maximum spacing between the approach roller 110 and the take-up column 1300 / take-up shaft from being less than or equal to a certain range (e.g., 1m), the substrate passes through the approach roller 110 to the take-up column 1300. As the thickness of the take-up column 1300 increases, the approach roller 110 needs to adaptively move away from the take-up column 1300 to adjust the substrate winding angle and tension within the limited adjustment space, while maintaining a stable preset distance. By using an adjustment mechanism to move the approach roller 110 outwards, it can continuously maintain the preset distance from the take-up column 1300 during operation, adapting to changes in the thickness of the take-up column 1300 and achieving stable tension control. That is, the adaptive mechanism 100 in this application can adaptively adjust the tension of the substrate in the take-up column 1300, achieving tension adjustment of the substrate in the take-up column 1300 within a limited length or space. The vertical space can be used to arrange the corresponding adjustment mechanism, and the adaptive tension adjustment effect is significant. Stable tension control can be achieved, so that the winding column can be wound smoothly and neatly. The wound substrate is tight and neat, and the rear end face is flat.

[0062] like Figures 4-8 As shown, the adjustment mechanism includes a first drive mechanism 120 and a second drive mechanism 130. The first drive mechanism 120 drives the second drive mechanism 130 to approach or move away from the take-up column 1300 on the first drive mechanism 120. The end of the pressure roller 110 is mounted on the second drive mechanism 130, and the second drive mechanism 130 drives the pressure roller 110 to approach or move away from the take-up column 1300 on the second drive mechanism 130.

[0063] Understandably, the first drive mechanism 120 and the second drive mechanism 130 can be used individually or in combination to adaptively adjust the distance between the pressure roller 110 and the outer surface of the take-up column 1300 in order to adjust the corresponding lateral tension. Specifically, after the substrate passes through the approach roller 110 to the winding column 1300, as winding begins, the thickness of the winding column 1300 increases. Since the approach roller 110 needs to adjust the substrate winding angle and tension within a limited adjustment space, it must adaptively move away from the winding column 1300 while maintaining a stable preset distance. The second drive mechanism 130 moves the approach roller 110 outward. Simultaneously, if the second drive mechanism 130 cannot continue to drive the approach roller 110 closer to or further away from the winding column 1300, and the distance between the approach roller 110 and the outer surface of the winding column 1300 exceeds the preset distance, the first drive mechanism 120 can be executed again to move it closer to the winding column 1300 to correct this. Similarly, the second drive mechanism 130 can further drive the approach roller 110 when the first drive mechanism 120 can no longer drive it closer to or further away, and the first drive mechanism 120 can correct this again. As can be seen, by using the first drive mechanism 120 alone, or the second drive mechanism 130 alone, or both in combination for one or more unidirectional and / or reverse driving actions, the proximity roller 110 can continuously maintain a preset distance from the winding column 1300 during operation, adapting to changes in the thickness of the winding column 1300, thereby achieving stable tension control. That is, the adaptive mechanism 100 of this application can adaptively adjust the distance between the proximity roller 110 and the winding column 1300, achieving tension adjustment of the winding material substrate within a limited length or space, thereby enabling the winding column to wind smoothly and neatly, resulting in a compact and neat substrate with a flat rear end face after winding.

[0064] In one embodiment, the first drive mechanism 120 and the second drive mechanism 130 near both sides of the pressure roller 110 are symmetrically arranged, which is more conducive to adjusting the tension of the roll substrate during the winding and unwinding process (especially the winding process of the winding column 1300).

[0065] In one embodiment, the first drive mechanism 120 includes a first power mechanism 121, a transfer base plate 122, and a first slide rail 123. The output end of the first power mechanism is connected to a gear 124. The transfer base plate 122 is mounted on the first slide rail 123, and a rack 125 is fixed on the transfer base plate 122. The gear 124 cooperates with the rack 125 to drive the transfer base plate 122 to move on the first slide rail 123.

[0066] In one embodiment, the first power mechanism 121 is a motor. Further, the motor can be a servo motor to achieve high-precision single-drive pitch. Even further, the motor can steplessly adjust the gear 124, thereby cooperating with the rack 125 to achieve precise drive.

[0067] In one embodiment, the rack 125 is fixedly mounted on the side of the transfer base plate 122, arranged along the length of the transfer base plate 122. Further, the rack 125 is detachably mounted on the side of the transfer base plate 122, that is, on the side of the transfer base plate 122 closest to the first power mechanism 121. The mating installation of the rack 125 with the transfer base plate 122 reduces the processing difficulty of the corresponding components, allowing the use of existing racks 125 to fit the transfer base plate 122; and the detachability of the rack 125 also facilitates the replacement of racks 125 with those requiring higher or lower precision.

[0068] In one embodiment, the second drive mechanism 130 includes a second power mechanism 131, a base slider 132, and a second slide rail 133. The second power mechanism 131 and the second slide rail 133 are both arranged on the transfer base plate 122. The second power mechanism 131 drives the base slider 132 to move on the second slide rail 133. The end near the pressure roller 110 is mounted on the base slider 132.

[0069] The first power mechanism 121 drives the gear 124 to rotate, and the gear 124, in turn, engages with the rack 125 on the transfer base plate 122 to drive the transfer base plate 122 to move on the first slide rail 123. Simultaneously, the second power mechanism 131 and the second slide rail 133 in the second drive mechanism 130 are both arranged on the transfer base plate 122, and the base slider 132, which connects to the end of the pressure roller 110, is arranged on the second slide rail 133. In other words, the entire second drive mechanism 130 is mounted on the transfer base plate 122. When the first power mechanism 121 drives the transfer base plate 122 to move, the second drive mechanism 130 on the transfer base plate 122 moves synchronously. That is, the first drive mechanism 120 can drive the second drive mechanism 130 to move and drive the approach pressure roller 110 connected to the second drive mechanism 130; the second drive mechanism 130 on the transfer base plate 122 can also independently drive the approach pressure roller 110; thus, the first drive mechanism 120 and the second drive mechanism 130 can realize the relatively independent driving of the approach pressure roller 110, and the first drive mechanism 120 and the second drive mechanism 130 can cooperate to move in the same direction or in opposite directions to realize the complex adjustment process of the approach pressure roller 110.

[0070] In one embodiment, the second power mechanism 131 is a cylinder. While its single-drive distance accuracy is lower than that of a motor, it can achieve rapid adjustment when the actual distance differs significantly from the preset distance. Furthermore, compared to a motor, a cylinder occupies less space and is less expensive, significantly reducing the overall equipment cost while still achieving adaptive distance adjustment. Understandably, the cylinder can operate in a fixed stepping mode. By controlling its airflow speed to match the roll material's movement speed, tension can be further adjusted and the unwinding and winding effects improved.

[0071] In one embodiment, the adaptive mechanism 100 also includes a transfer roller 140 adjacent to the pressure roller 110. When the first drive mechanism 120 drives the second drive mechanism 130 to move, the transfer roller 140 is moved synchronously with the second drive mechanism 130, which further improves the accuracy and effectiveness of tension adjustment, so that the winding column can be wound up smoothly and neatly, and the wound substrate is tight and neat, and the rear end face of the winding is flat.

[0072] In one embodiment, the transfer roller 140 is arranged in a direction away from the take-up column 1300, and the approach pressure roller 110 is located between the take-up column 1300 and the transfer roller 140. The end of the transfer roller 140 is fixedly connected to the first drive mechanism 120, and the first drive mechanism 120 drives the transfer roller 140 to approach or move away from the take-up column 1300 on the first drive mechanism 120.

[0073] For example, the substrate is wound up above the transfer roller 140, below the pressure roller 110, and above the take-up column 1300. The transfer roller 140 effectively guides the upstream substrate to the take-up column 1300, forming a tension adjustment area between the transfer roller 140 and the take-up column 1300. The transfer roller 140 moves with the first drive mechanism 120, which helps to adapt the tension adjustment area to the distance from the pressure roller 110, improving the accuracy and effectiveness of tension adjustment. Furthermore, the first drive mechanism 120 drives the transfer roller 140 synchronously with the second drive mechanism 130, moving it closer to or further away from the take-up column 1300. The transfer roller 140 moves under the drive of the first drive mechanism 120. Furthermore, when the take-up column 1300 is in a winding position, the upper surface of the roll is higher than the lower surface of the pressure roller 110, and the upper surface of the transfer roller 140 is higher than the lower surface of the pressure roller 110.

[0074] In one embodiment, the end of the transfer roller 140 is mounted on the transfer base plate 122 near the side of the approach pressure roller 110 via a transfer roller bracket 141. That is, as the transfer base plate 122 moves, the end of the transfer roller 140 moves synchronously, thereby maintaining adaptive following movement between the transfer roller 140 and the approach pressure roller 110 within a large adjustment range. The end of the transfer roller 140 is mounted on the side of the first drive mechanism 120 near the transfer roller 140 via a transfer roller 140 bracket, and the transfer roller bracket 141 and the second drive mechanism 130 are driven to move synchronously by the first drive mechanism 120. Further, the transfer roller bracket 141 has a bent structure, with the upper part of the transfer roller 140 bracket extending away from the take-up column 1300 to form a transfer roller 140 mounting section, and the end of the transfer roller 140 is fixed to the corresponding side transfer roller 140 mounting section.

[0075] In one embodiment, the end of the transfer roller 140 is mounted on the transfer roller bracket 141 via an adjusting seat 201. Further, the adjusting seat 201 includes a limiting protrusion 201A, a fixing block 201B, and a fixing block bolt (not shown in the figure). The limiting protrusion 201A is located outside the fixing block 201B, and an adjustment gap is provided between the limiting protrusion 201A and the fixing block 201B. The end of the transfer roller body is mounted on the fixing block 201B, which is provided with a fine-tuning elongated hole. The fine-tuning elongated hole, in conjunction with the fixing block bolt, adjusts the position of the fixing block inside the limiting protrusion 201A. Tightening or loosening the fixing block bolt adjusts the position of the fixing block 201B relative to the limiting protrusion 201A, thereby fine-tuning the end position of the transfer roller 140. The adjusting seat 201 allows for fine-tuning and correction of the transfer roller 140, achieving smooth and efficient substrate feeding and improving operational stability.

[0076] In one embodiment, the adaptive mechanism 100 further includes a detection unit (not shown) for detecting the distance between the approach pressure roller 110 and the outer surface of the winding column 1300, or detecting the tension of the substrate to be wound on the winding column 1300 during the winding process. The detection unit can directly or indirectly measure the distance between the approach pressure roller 110 and the outer surface of the winding column 1300, or the real-time tension during the winding process. This information is then fed back to the first drive mechanism 120 and the second drive mechanism 130, which make corresponding reciprocating adjustments to adjust the actual distance between the approach pressure roller 110 and the outer surface of the winding column 1300 to a preset distance. Continuous detection and adjustment achieve stable adaptive tension adjustment, enabling the winding column to wind smoothly and neatly, resulting in a compact and neat substrate with a flat rear end face after winding.

[0077] In one embodiment, the detection unit is electrically connected to the first drive mechanism 120 and the second drive mechanism 130.

[0078] In one embodiment, the detection unit may be arranged on the first drive mechanism 120, or on the second drive mechanism 130, or near the end side of the pressure roller 110, or on the mounting surface of the first drive mechanism 120, etc.

[0079] In one embodiment, the take-up and unwind integrated device 1000 further includes a traction mechanism 300, which includes a drive roller body 310 that is driven to rotate, a traction rubber roller 350, and an arrangement wall plate 320. The arrangement wall plate 320 is detachably installed on the rear side of the main support 1100. The ends of the drive roller body 310 and the traction rubber roller 350 are both installed on the arrangement wall plate 320, and the traction rubber roller 350 is located above and / or below the drive roller body 310.

[0080] For multi-layered substrates, the unwinding process may also involve a substrate separation step. For example, if the substrate is a composite substrate 2000, including a first composite substrate 2100 and a second composite substrate 2200, the unwinding column 1200 unwinds the composite substrate 2000. Before reaching the traction mechanism 300, the composite substrate 2000 is separated into the first substrate 2100 and the second substrate 2200. At this time, the first substrate 2100 travels towards the winding column 1300 via the traction mechanism 300 and is wound up, while the second substrate 2200 is guided by other rollers 1400 to another downstream processing area for transmission. In one example of the traction process, the drive roller 310 and the traction roller 350 cooperate to clamp the first substrate 2100. The drive roller 310 is driven to move the first substrate 2100, while the traction roller 350 keeps the surface of the first substrate 2100 in contact with the surface of the drive roller 310, thereby causing the corresponding first substrate 2100 to be pulled out.

[0081] In one embodiment, the arrangement wall panel 320 is a detachable structure. When the drive roller body 310, the traction rubber roller 350 and the corresponding traction drive mechanism are all arranged on the arrangement wall panel 320, the traction mechanism 300 is also relatively independent and can be disassembled and maintained separately relative to the overall winding and unwinding device, which improves the maintainability of the structure and ensures the installation and disassembly effect.

[0082] In one embodiment, the traction mechanism 300 is located between the unwinding column 1200 and the winding column 1300 in the vertical direction (longitudinal direction of the unwinding and winding integrated device), and the traction mechanism 300 is located behind the main support 1100 in the horizontal direction relative to the unwinding column 1200.

[0083] In one embodiment, the end of the drive roller body 310 is mounted on the arrangement wall plate 320 via a quick-release mounting plate 330; a quick-release opening 321 is provided on the edge side of the arrangement wall plate 320; the quick-release mounting plate 330 is detachably mounted on the arrangement wall plate 320, and the side of the quick-release mounting plate 330 is engaged with the quick-release opening 321; the end of the drive roller body 310 is fixed to the corresponding side quick-release mounting plate 330. Through the quick-release structure, on the one hand, the drive roller body 310 can be disassembled without removing the arrangement wall plate 320, only by removing the quick-release mounting plate 330, and the entire drive roller body 310 can be taken out from the quick-release opening 321; on the other hand, in addition to being fixed to the arrangement wall plate 320 by the quick-release mounting plate 330, the engagement of the side of the quick-release mounting plate 330 with the quick-release opening 321 can improve the corresponding installation accuracy and stability, which, combined with the characteristic that the roller body needs to be disassembled and installed periodically, ensures the corresponding installation and production effects. The quick-release drive roller body 310 facilitates disassembly and grinding without requiring disassembly of the corresponding traction mechanism 300 or the overall frame of the winding / unwinding device, thus improving the operability of the corresponding drive roller body 310 and traction mechanism 300. Furthermore, the quick-release mounting plates 330 on both sides are located on the same side relative to the two side arrangement wall panels 320; for example, the quick-release mounting plates 330 can be detachably and fixedly installed on the left side of the arrangement wall panel 320, and the quick-release mounting plates 330 are held in place by the quick-release opening 321 on the right side.

[0084] In one embodiment, the quick-release mounting plate 330 has a protruding structure 331 on one side near the quick-release opening 321, and the outer periphery of the protruding structure 331 matches the shape of the inner side of the quick-release opening 321. Unlike directly using the front or rear side of the quick-release mounting plate 330 for clamping, this embodiment uses a protruding structure 331 provided from the side for clamping; this allows the quick-release mounting plate 330 to be fixedly installed to the wall panel 320, avoiding the quick-release mounting plate 330 itself bearing the full weight load, thus preventing or reducing damage to the quick-release mounting plate 330; at the same time, it also enhances installation stability and improves installation convenience and accuracy. Furthermore, the quick-release mounting plate 330 is provided with fixing holes, and the wall panel 320 is provided with corresponding mounting holes; it is understood that the quick-release mounting plate 330 can be installed through the fixing holes and mounting holes using fasteners such as screws, thus improving installation accuracy.

[0085] In one embodiment, the quick-release opening 321 is a U-shaped opening, and the raised structure 331 is a circular raised structure 331. In specific machining, when the mating structure is a cuboid and a corresponding concave body, the error of this type of mating structure is usually increased, such as when the raised structure 331 is a cuboid structure; the increased error will affect the installation and arrangement accuracy of the drive roller body 310; and this type of mating structure has high processing requirements for both the mating side and the mated side. If the mating error needs to be reduced, the corresponding further processing cost will often increase. This application uses a circular raised structure 331 and a U-shaped opening for mating, which is easier to fit and has a smaller mating error. The outer periphery of the circular raised structure 331 is easy to fit with the inner arc of the U-shaped opening; due to its easier mating characteristic, the processing requirements of this type of mating structure are relatively low, and processing costs can be effectively reduced while ensuring the mating accuracy.

[0086] In one embodiment, the traction mechanism 300 further includes a limiting top block 322, used to prevent the quick-release mounting plate 330 from detaching from the opening side of the quick-release opening 321, further stabilizing the position of the quick-release mounting plate 330, and thus further stabilizing the position of the drive roller body 310, improving the overall structural installation stability, and preventing the quick-release mounting plate 330 from detaching due to accidental contact after disassembly. Furthermore, the limiting top block 322 is detachably mounted on the opening side of the quick-release opening 321, and the limiting top block 322 extends to form a blocking and limiting portion on the side near the quick-release mounting plate 330. Even further, limiting top blocks 322 are provided above and below the quick-release opening 321.

[0087] In one embodiment, the drive roller body 310 is driven to rotate by a traction drive motor 340. The traction drive motor 340 is mounted on the arrangement wall panel 320 via a quick-release mounting plate 330, and the traction drive motor 340 is fixed to the side of the corresponding quick-release mounting plate 330 away from the quick-release opening 321. The quick-release mounting plate 330 has a mounting hole, and the motor shaft of the traction drive motor 340 is connected to the end of the corresponding drive roller body 310 through the mounting hole. When the quick-release mounting plate 330 is provided with a circular protrusion structure 331, the mounting hole is located in the center of the circular protrusion. Further, one end of the drive roller body 310 is connected to the traction drive motor 340, and the other end of the drive roller body 310 is connected to a drive roller bearing seat 311, which is fixed to the corresponding quick-release mounting plate 330; and the drive roller bearing seat 311 is fixed to the side of the corresponding quick-release mounting plate 330 away from the quick-release opening 321. The drive roller body 310 is connected to the end side of the traction drive motor 340 and is also provided with an auxiliary bearing seat 312 and a vertical bearing 313. The auxiliary bearing seat 312 is fixed to the side of the wall plate 320 on this side away from the traction drive motor 340, and the vertical bearing 313 is installed above the auxiliary bearing seat 312. The vertical bearing 313 is installed in conjunction with the end of the corresponding drive roller.

[0088] In one embodiment, a perforated operating area 323 is provided on the front side of the wall panel 320, and multiple fixing holes are provided at the front end of the perforated operating area 323. And / or, an auxiliary positioning plate 324 extends to the side from the front end of the perforated operating area 323. The perforated operating area 323 facilitates the operation and installation of the wall panel 320 by the operator, while the multiple fixing holes allow the front side of the wall panel 320 to be detachably installed with other structures (such as the main wall panel 1120 in the main support 1100). The auxiliary positioning plate 324, in addition to assisting in the installation and positioning of the wall panel 320, also helps to enhance the stability of the wall panel 320 installation.

[0089] In one embodiment, the end of the traction roller 350 is mounted on the arrangement wall panel 320 via a guide drive mechanism 351. The guide drive mechanism 351 includes a traction guide rail fixed to the arrangement wall panel 320, a traction cylinder, and a traction slider that moves on the traction guide rail driven by the traction cylinder. The end of the corresponding traction roller 350 is connected to the traction slider. During the traction process, the guide drive mechanism 351 drives the traction roller 350 to move (including moving away from or towards the drive roller body 310), thereby cooperating to achieve material support and traction. Furthermore, the guide rail direction is vertical (the longitudinal direction of the winding and unwinding integrated device 1000).

[0090] In one embodiment, one or more fixing rods 360 are provided between the wall panels 320 on both sides. Furthermore, at least two or more fixing rods 360 are fixed diagonally. The fixing rods 360 secure the installation position between the wall panels 320 on both sides and strengthen the overall structural load. Providing two or more diagonally fixed rods 360 facilitates the arrangement of other components, strengthens the structure, and provides operational space.

[0091] In one embodiment, a floating roller device 400 is also provided on the side of the unwinding column 1200. The floating roller device 400 includes a floating roller mounting main board 410, a floating roller driving mechanism 450, a floating roller body 420, and a counterweight assembly 440. The main support 1100 includes a base 1110 and main wall plates 1120 on both sides of the base 1110. The floating roller mounting main board 410 is rotatably mounted on the main wall plate 1120. The floating roller driving mechanism 450 drives the floating roller mounting main board 410 to rotate. The end of the floating roller body 420 is installed on one side of the rotation center of the floating roller mounting main board 410. The counterweight assembly 440 is disposed on the other side of the rotation center of the floating roller mounting main board 410. The floating roller drive mechanism 450 of this application drives the floating roller mounting main board 410 to rotate, thereby causing the floating roller body 420 to swing around the rotation center as the swing base point for corresponding tension adjustment. The counterweight component 440 is set on the opposite side of the floating roller body 420, which is conducive to counterweight balance based on the self-weight of the floating roller body 420 and avoids the influence of the self-weight of the floating roller body 420 on the accuracy. Through the balance of the counterweight component 440, the driving degree of the floating roller drive mechanism 450 can be precisely matched with the tension adjustment degree, thereby improving the adjustment accuracy of the floating roller device 400. Moreover, the counterweight component 440 can also be adjusted according to other weights that may cause errors, and there are multiple adjustment methods suitable for different application scenarios. It is worth noting that the floating roller device 400 includes the floating roller mounting main board 410 and the floating roller drive mechanism 450. Both ends of the floating roller body 420 are mounted on the corresponding side floating roller mounting main board 410. The floating roller mounting main board 410 is rotatably mounted on the corresponding side main wall plate and is driven by the corresponding side floating roller drive mechanism 450 to swing.

[0092] In one embodiment, the counterweight assembly 440 includes a counterweight rod 441 and weights 442 mounted on the counterweight rod 441. Further, the counterweight rod 441 is mounted on the side of the float roller mounting plate 410 opposite to the float roller body 420, and the weights 442 are detachably sleeved on the counterweight rod 441. Further, the weight of the counterweight rod 441 is less than the weight of the float roller body 420; the use of weights 442 for counterweighting allows for more flexible configuration, and different specifications of weights 442 can be used to adjust the balance.

[0093] In one embodiment, a limiting block 401 is provided on the main wall plate 1120 above and / or below the floating roller mounting main plate 410. Further, the main wall plate 1120 also provides limiting blocks 401 above and below the side of the floating roller mounting main plate 410 where the counterweight assembly 440 is arranged. By using the limiting blocks 401 to assist in restricting the rotational position of the floating roller mounting main plate 410, the load on the corresponding drive mechanism is reduced, damage to the drive mechanism is avoided, and the service life of the overall floating roller device 400 is improved.

[0094] In one embodiment, anti-collision pads 412 are installed on the upper and / or lower ends of the side where the counterweight assembly 440 is arranged on the floating roller mounting main board 410. The anti-collision pads 412 are set in conjunction with the limiting block 401 to prevent the floating roller mounting main board 410 from directly colliding with the limiting block 401 due to excessive rotation.

[0095] In one embodiment, the floating roller device 400 further includes a rotating shaft 430, which passes through the floating roller main plate and is mounted on the corresponding side main wall plate 1120. The rotating shaft 430 forms the rotation center of the floating roller mounting main plate 410. When the drive mechanism drives the floating roller mounting main plate 410 to rotate, the floating roller mounting main plate 410 rotates around the rotating shaft 430. The side of the floating roller mounting main plate 410 near the floating roller body 420 forms a swing arm, causing the floating roller body 420 to swing. The counterweight assembly 440 is located on the side of the floating roller mounting main plate 410 opposite to the floating roller body 420, at least balancing the weight of the floating roller body 420.

[0096] In one embodiment, the floating roller drive mechanism 450 includes a floating roller telescopic cylinder 451, which is mounted on the main wall panel 1120. The floating roller mounting main plate 410 extends upward to form a connecting portion 411, and the output end of the floating roller telescopic cylinder 451 is rotatably connected to the upper connecting portion 411 of the floating roller mounting main plate 410. Further, in the length direction of the floating roller mounting main plate 410, the connecting portion 411 is located between the floating roller body 420 and the rotating shaft 430.

[0097] In one embodiment, the main support 1100, in addition to serving as a support, can also function as a web-correcting conveyor device. It includes a base 1110, a first web-correcting mechanism 220, two main wall panels 1120 on both sides, an upper base plate 1130, and a second web-correcting mechanism 230. The first web-correcting mechanism 220 is arranged above the base 1110, the main wall panels 1120 are arranged on the first web-correcting mechanism 220, the upper base plate 1130 is arranged above the main wall panels 1120, and the second web-correcting mechanism 230 is arranged on the upper base plate 1130. The unwinding column 1200 and the guide roller 1400 are installed between the two main wall panels 1120, and the winding column 1300 and the adaptive mechanism 100 are installed on the second web-correcting mechanism 230. The first correction mechanism 220 is used to adjust the position of the unwinding column 1200 at least along its length, and the second correction mechanism 230 is used to adjust the position of the winding column 1300 at least along its length. Furthermore, the main support 1100 is also equipped with an offset detection sensor (not shown in the figure) to detect whether the unwinding column 1200, the winding column 1300, or the position of the roll (substrate) are offset.

[0098] For example, the first correction mechanism 220 is used for correction, moving the main structure including the main wall panel 1120, the unwinding column 1200, the upper base plate 1130, the second correction mechanism 230, and the winding column 1300 to ensure that the unwinding side is corrected to a suitable unwinding position, including a suitable position relative to other downstream transmission directions; the second correction mechanism 230 is used for correction, moving the top structure including the winding column 1300 to ensure that the winding side is corrected to a suitable winding position, thereby achieving stable unwinding and winding after correction. Traditional unwinding and winding integrated devices typically place the unwinding and winding sides in separate horizontally separated frames, still requiring a certain amount of installation space. In this application, however, the unwinding and winding are concentrated in the less utilized vertical space, achieving integrated unwinding and winding while simultaneously ensuring correction at different positions; moreover, the structure is stable, easy to operate, and convenient for installation, arrangement, and maintenance.

[0099] In one embodiment, the first correction mechanism 220 includes a first guide component 221 and a lower base plate 222, wherein the first guide component 221 is installed between the base 1110 and the lower base plate 222, and the main wall plate 1120 is installed on the lower base plate 222; the lower base plate 222 is driven to move the main wall plate 1120 relative to the base 1110 on the first guide component 221.

[0100] In one embodiment, a plurality of first guide components 221 are arrayed between the lower base plate 222 and the base 1110, with corresponding first guide components 221 arranged on the left and right sides and at the front and rear positions. Further, each first guide component 221 includes a first guide rail (not shown in the figure) and a first guide slider (not shown in the figure). The first guide rail is fixed to the base 1110, the first guide slider cooperates with the first guide rail, and the top of the first guide slider is fixedly connected to the lower base plate 222. The arrayed distribution of multiple first guide components 221 improves guiding accuracy, and the multiple positions restrict the guiding direction, overcoming guiding deviations that may be caused by component errors. Simultaneously, setting multiple first guide components 221 in corresponding layers enhances their support for the upper structure, strengthening the overall structural stability.

[0101] In one embodiment, a positioning post 223 is provided on the lower base plate 222, and a corresponding positioning hole 224 is provided on the base 1110. The positioning post 223 sinks down and cooperates with the positioning hole 224 to position the relative position before or after correction. The positioning post 223 is a movable positioning post 223. When the lower base plate 222 moves to the position where the positioning post 223 cooperates with the positioning hole 224, the positioning post 223 sinks due to its own weight, thereby cooperating with the positioning hole 224 to achieve the corresponding positioning.

[0102] In one embodiment, the first correction mechanism 220 further includes a first cylinder. The lower base plate 222 has an installation opening, and the first cylinder 220A is arranged on the base 1110 through the installation opening. The output end of the first cylinder 220A is connected to the lower base plate 222, and the first cylinder 220A drives the lower base plate 222 to move relative to the base 1110 on the first guide assembly 221. In one embodiment of this application, the direction of action of the first cylinder 220A, i.e., the extension / retraction direction, is consistent with the guiding direction of the first guide assembly 221. The lower base plate 222 is moved by pushing or pulling back using the output end of the first cylinder 220A. The arrangement of the first cylinder 220A on the base 1110 through the installation opening of the lower base plate 222 facilitates the connection between the output end of the first cylinder 220A and the inner side of the installation opening of the lower base plate 222, thereby allowing for direct pushing and pulling of the lower base plate 222 from the inside, fully utilizing the internal horizontal space and any excess vertical clearance. Furthermore, a mounting portion is formed on the inner side of the mounting opening of the lower base plate 222, and the output end of the first cylinder 220A is fixedly connected to the mounting portion.

[0103] In one embodiment, the second correction mechanism 230 includes a second guide assembly 231 and a top plate 232, wherein the top plate 232 is located above the upper base plate 1130, the second guide assembly 231 is installed between the upper base plate 1130 and the top plate 232, and the winding column 1300 and the adaptive mechanism 100 are installed on the top plate 232; the top plate 232 is driven to move the winding column 1300 and the adaptive mechanism 100 relative to the upper base plate 1130 on the second guide assembly 231. Further, the first guide assembly 221 is installed on the base 1110 via a pad. The lower base plate 222 cooperates with the first guide component 221 to form a guide sliding structure. When the lower base plate 222 is driven by an external force, it can move relative to the base 1110 along the guide direction of the first guide component 221 to correct the unwinding column 1200 above the inner lower base plate 222 to a suitable position. Similarly, the top plate 232 cooperates with the second guide component 231 to form a guide sliding structure. When the top plate 232 is driven by an external force, it can move relative to the upper base plate 1130 along the guide direction of the second guide component 231 to correct the unwinding column 1300 above the top plate 232 to a suitable position.

[0104] In one embodiment, a plurality of second guide components 231 are arrayed between the top plate 232 and the upper base plate 1130, with corresponding second guide components 231 arranged on the left and right sides, front and rear positions. Further, each second guide component 231 includes a second guide rail (not shown in the figure) and a second guide slider (not shown in the figure). The second guide rail is fixed to the upper base plate 1130, and the second guide slider cooperates with the second guide rail, with the top end of the second guide slider fixedly connected to the top plate 232. The arrayed distribution of multiple second guide components 231 improves guiding accuracy, and the multiple positions restrict the guiding direction, overcoming guiding deviations that may be caused by component errors. Simultaneously, the placement of multiple second guide components 231 in corresponding layers enhances their support for the upper structure, strengthening the overall structural stability.

[0105] In one embodiment, the top plate 232 has a U-shaped structure, and the winding column 1300 is arranged on the opening side of the U-shaped structure of the top plate 232. In one embodiment of this application, by arranging the winding column 1300 on the opening side of the U-shaped structure, it is beneficial to make full use of the remaining longitudinal space, and to use the space above and below the opening of the top plate 232 to provide space for the winding column 1300 to cover the rolled material and rotate; in addition to improving space utilization and avoiding the inconvenience of installation due to the longitudinal structure being too high, it is also beneficial to facilitate the installation of other components on the top plate 232 with the winding column 1300, thereby improving the operating efficiency.

[0106] In one embodiment, the second correction mechanism 230 further includes a second cylinder 230A, which is mounted on one side of the upper base plate 1130 and its output end is connected to one side of the top plate 232. The second cylinder 230A drives the top plate 232 to move relative to the upper base plate 1130 on the second guide assembly 231. In one embodiment of this application, the output end of the second cylinder 230A is connected to the side of the top plate 232. When the output end of the second cylinder 230A extends or retracts, it drives the top plate 232 along the guiding direction of the second guide assembly 231. Further, the second cylinder 230A is mounted on one side of the upper base plate 1130 via an L-shaped fixing seat; the output end of the second cylinder 230A is connected to the side or side portion of the top plate 232. The second cylinder 230A is arranged using the space of the upper base plate 1130, and its output end is connected to the side portion of the top plate 232 to effectively provide driving force.

[0107] In one embodiment, upper base plates 1130 are provided on both sides of the main support 1100, and a support rod 202 is provided between the upper base plate 1130 and the lower base plate 222. The upper base plates on both sides are respectively installed above the side wall panels. The upper base plate 1130 is eccentrically positioned relative to the corresponding side wall panel. The lower part of the upper base plate 1130 near the winding column 1300 is connected to the corresponding wall panel, and the lower part of the upper base plate 1130 away from the winding column 1300 is connected to the upper end of the support rod 202. The lower base plate 222 extends to form a supporting part protruding from the wall panel, and the supporting part is connected to the lower end of the support rod 202. Through the upper base plates 1130 on both sides, on the one hand, the arrangement position of the guide mechanism can be guaranteed, thereby providing relative movement of the top plate 232. On the other hand, the connection between the space between the main wall panels 1120 and the structure above the top plate 232 is maintained, thereby facilitating the arrangement of the material path of the overall mechanism. Meanwhile, the upper base plate 1130 is eccentrically arranged to cooperate with the lower base plate 222 and support rod 202 on the outside, thereby improving the overall structural load-bearing stability and enhancing the integrity of the structure above the first correction mechanism 220, thus improving the correction effect.

[0108] In one embodiment, the number of guide rollers 1400 is one or more. Further, the number of guide rollers 1400 is two or more. The ends of the guide rollers 1400 are mounted on corresponding mounting surfaces via adjusting seats 201. The adjusting seat 201 includes an outer limiting protrusion, an inner fixing block, and fastening bolts, with an adjustment gap between the limiting protrusion and the fixing block. The end of the guide roller 1400 is mounted on the fixing block, which has an elongated hole. The elongated hole, in conjunction with the fastening bolts, adjusts the position of the fixing block inside the limiting protrusion. When the guide rollers 1400 are installed between the main wall panels 1120, the mounting surface is the surface of the main wall panel 1120, the limiting protrusion is mounted on the main wall panel 1120, and the limiting protrusion is located outside the fixing block. The adjusting seat 201 allows for fine-tuning of the end position of the guide rollers 1400, thereby adjusting the parallelism of the guide rollers 1400, etc., for adjustment of material feeding during production and periodic maintenance.

[0109] In one embodiment, a plurality of reinforcing rods 203 are provided between the main wall panels 1120. The reinforcing rods 203 can enhance the overall structural stability and ensure longitudinal support for the upper components.

[0110] Another object of this application is to provide a composite current collector production system, including the above-described integrated take-up and unwinding device. It is understood that this composite current collector production system also possesses the advantages of the above-described integrated take-up and unwinding device.

[0111] In one embodiment, in the integrated unwinding and take-up device, the unwinding column unwinds a composite substrate 2000, which includes a release film layer and a base layer with an adhesive layer on its surface. Further, at least the traction mechanism 300 pulls the base layer towards the take-up column 1300, which can then wind the base layer, guiding the release film layer downstream. The composite substrate 2000 is separated into the release film and the base layer before reaching the traction mechanism 300 and approaching the pressure roller. A cathode roller or similar device can be arranged downstream of this integrated unwinding and take-up device to form a composite current collector production system for producing composite current collectors.

[0112] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. However, those skilled in the art will understand that the embodiments described below are some embodiments of this application, but not all embodiments, and are only used to illustrate this application, and should not be regarded as limiting the scope of this application.

[0113] Example 1

[0114] like Figures 1-3As shown, this embodiment discloses an integrated unwinding and take-up device 1000, including: an unwinding column 1200, a take-up column 1300, a guide roller 1400, an adaptive mechanism 100, and a main support 1100. The unwinding column 1200, the guide roller 1400, the take-up column 1300, and the adaptive mechanism 100 are all arranged on the main support 1100. The take-up column 1300 is disposed above the unwinding column 1200, and the guide roller 1400 is disposed between the unwinding column 1200 and the take-up column 1400. Between the columns 1300; the adaptive mechanism 100 includes a proximity pressure roller 110 and an adjustment mechanism, the proximity pressure roller 110 being disposed on the adjustment mechanism, and the proximity pressure roller 110 being disposed adjacent to the winding column 1300; the adjustment mechanism adaptively adjusts the distance between the proximity pressure roller 110 and the outer surface of the winding column 1300 to adjust the winding tension; the substrate feeds along a path formed in the sequence of unwinding column 1200, passing roller 1400, proximity pressure roller 110, and winding column 1300. Specifically, the adjustment mechanism adaptively moves the proximity pressure roller 110 to maintain the distance between the proximity pressure roller 110 and the outer surface of the winding column 1300 at a preset distance; the substrate includes flexible substrates such as film rolls. The unwinding column 1200 is formed by the unwinding shaft and its outer substrate. When the unwinding shaft is covered with a substrate, the unwinding column 1200 is formed by the unwinding shaft and its outer substrate together. When the unwinding shaft is not covered with a substrate, the unwinding column 1200 is simply the unwinding shaft. Similarly, the winding column 1300 is formed by the winding shaft and its outer substrate. When the winding shaft is not covered with a substrate, the winding column 1300 is simply the winding shaft. In this embodiment, the main support 1100 includes a base 1110 and main wall panels 1120 on both sides of the base 1110. The unwinding column 1200 and the guide roller 1400 are installed between the two main wall panels 1120. The winding column 1300 and the adaptive mechanism 100 are installed above the main wall panels 1120. There is also a top plate 232 above the main wall panels 1120. The winding column 1300 and the adaptive mechanism 100 are installed on the top plate 232.

[0115] When the winding column 1300 is winding and the diameter increases, the adjustment mechanism moves the approach pressure roller 110 away from the winding column 1300, so that the approach pressure roller 110 and the outer surface of the winding column 1300 maintain a stable preset distance or preset distance range (when an allowable error exists, the preset distance range is the preset distance ± error), thereby controlling the substrate tension on one side of the winding column 1300.

[0116] like Figures 4-8As shown, the adjustment mechanism includes a first drive mechanism 120 and a second drive mechanism 130. The first drive mechanism 120 drives the second drive mechanism 130 to move closer to or away from the take-up column 1300 on the first drive mechanism 120. The end of the approach pressure roller 110 is mounted on the second drive mechanism 130, and the second drive mechanism 130 drives the approach pressure roller 110 to move closer to or away from the take-up column 130 on the second drive mechanism 130. In this embodiment, the first drive mechanism 120 and the second drive mechanism 130 on both sides of the approach pressure roller 110 are symmetrically arranged. The first drive mechanism 120 and the second drive mechanism 130 are arranged in a narrow space and cooperate to achieve a common total stroke greater than the stroke of the first drive mechanism 120 or the second drive mechanism 130. When the take-up column 1300 is running, the second drive mechanism 130 moves the approach pressure roller 110 outward. Simultaneously, if after a single minimum drive by the second drive mechanism 130, the distance between the approach pressure roller 110 and the outer surface of the take-up column 1300 exceeds a preset distance, the first drive mechanism 120 can be executed again to move closer to the take-up column 1300 to correct this. Similarly, the second drive mechanism 130 can further drive the approach pressure roller 110 when the first drive mechanism 120 can no longer drive it closer or further away, and can again be corrected by the first drive mechanism 120. Through one or more drives in the same or opposite directions by the first drive mechanism 120 and the second drive mechanism 130, the approach pressure roller 110 can continuously maintain a preset distance from the take-up column 1300 during operation, adapting to changes in the thickness of the take-up column 1300 and achieving stable tension control.

[0117] In the specific implementation of the first driving mechanism 120 and the second driving mechanism 130, the first driving mechanism 120 includes a first power mechanism 121, a transfer base plate 122, and a first slide rail 123. The output end of the first power mechanism 121 is connected to a gear 124. The transfer base plate 122 is mounted on the first slide rail 123, and a rack 125 is fixed on the transfer base plate 122. The gear 124 cooperates with the rack 125 to drive the transfer base plate 122 to move on the first slide rail 123. And / or, the second driving mechanism 130 includes a second power mechanism 131, a base slider 132, and a second slide rail 133. The second power mechanism 131 and the second slide rail 133 are both arranged on the transfer base plate 122. The second power mechanism 131 drives the base slider 132 to move on the second slide rail 133, and the end near the pressure roller 110 is mounted on the base slider 132. The first power mechanism 121 drives the gear 124 to rotate, and the gear 124, in turn, engages with the rack 125 on the transfer base plate 122 to drive the transfer base plate 122 to move on the first slide rail 123. Simultaneously, the second power mechanism 131 and the second slide rail 133 in the second drive mechanism 130 are both arranged on the transfer base plate 122, and the base slider 132 connecting to the end of the pressure roller 110 is arranged on the second slide rail 133. That is, the entire second drive mechanism 130 is set on the transfer base plate 122. When the first power mechanism 121 drives the transfer base plate 122 to move, the second drive mechanism 130 on the transfer base plate 122 moves synchronously. In other words, the first drive mechanism 120 can drive the second drive mechanism 130 to move, and thus move the pressure roller 110 on the second drive mechanism 130; at the same time, the second drive mechanism 130 on the transfer base plate 122 can also independently drive the pressure roller 110. In this embodiment, the first drive mechanism 120 and the second drive mechanism 130 achieve relatively independent driving of the approach pressure roller 110, and can cooperate to move in the same or opposite directions to realize the complex adjustment process of the approach pressure roller 110. Furthermore, the first power mechanism 121 can be a motor, and the second power mechanism 131 can be a cylinder. The motor can steplessly adjust the gear 124, thereby cooperating with the rack 125 to achieve precise driving; while the cylinder typically operates in a fixed stepping mode.

[0118] To simplify the structure of the required components, in this embodiment, the rack 125 is fixedly installed on the side of the transfer base plate 122 and arranged along the length of the transfer base plate 122. The rack 125 is detachably installed on the side of the transfer base plate 122, that is, on the side of the transfer base plate 122 near the first power mechanism 121.

[0119] To create a relatively independent tension adjustment area on the take-up side and improve the adjustment effect of the proximity pressure roller 110, in this embodiment, the adaptive tension adjustment mechanism also includes a transfer roller 140 adjacent to the proximity pressure roller 110. The proximity pressure roller 110 is located between the take-up column 1300 and the transfer roller 140. The end of the transfer roller 140 is fixedly connected to the first drive mechanism 120. Specifically, the end of the transfer roller 140 is mounted on the transfer base plate 122 near the side of the transfer roller 140 via a transfer roller bracket 141. As the transfer base plate 122 moves, the end of the transfer roller 140 moves synchronously, that is, the transfer roller 140 moves with the drive of the first drive mechanism 120. The first drive mechanism 120 drives the transfer roller 140 and the second drive mechanism 130 to move closer to or away from the take-up column 1300 synchronously on the first drive mechanism 120. The substrate is wound up at least above the transfer roller 140, below the proximity pressure roller 110, and above the take-up column 1300. The upper surface of the take-up shaft is higher than the lower surface of the pressure roller 110, and the upper surface of the transfer roller 140 is higher than the lower surface of the pressure roller 110. In this embodiment, the transfer roller support 141 is a bent structure, and the upper part of the transfer roller support 141 extends away from the take-up column 1300 to form a transfer roller 140 mounting section. The end of the transfer roller 140 is fixed to the corresponding side transfer roller 140 mounting section.

[0120] The end of the transfer roller 140 is mounted on the transfer roller bracket 141 via an adjusting seat 201. The adjusting seat 201 includes a limiting protrusion 201A, a fixing block 201B, and a fixing block 201B bolt. The limiting protrusion 201A is located outside the fixing block 201B, and an adjustment gap is left between the limiting protrusion 201A and the fixing block 201B. The end of the transfer roller 140 is mounted on the fixing block 201B. The fixing block 201B is provided with an elongated hole, which, in conjunction with the fixing block 201B bolt, adjusts the position of the fixing block 201B inside the limiting protrusion 201A. By tightening or loosening the fixing block 201B bolt, the position of the end of the transfer roller 140 can be finely adjusted relative to the inner position of the fixing block 201B relative to the limiting protrusion 201A.

[0121] like Figures 9-14As shown, in this embodiment, the take-up and unwind integrated device 1000 further includes a traction mechanism 300. The traction mechanism 300 includes a drive roller body 310 that is driven to rotate, a traction rubber roller 350, and an arrangement wall plate 320. The arrangement wall plate 320 is detachably installed on the rear side of the main support 1100 (in this embodiment, it is detachably installed on the rear side of the main wall plate 1120). The ends of the drive roller body 310 and the traction rubber roller 350 are both installed on the arrangement wall plate 320, and the traction rubber roller 350 is located below the drive roller body 310. For multi-layered substrates, the unwinding process may also involve a composite substrate 2000 separation step. For example, if the substrate is a composite substrate 2000, including a composite first substrate 2100 and a second substrate 2200, the unwinding column 1200 of this application unwinds the composite substrate 2000. Before traveling to the traction mechanism 300, the composite substrate 2000 is separated into a first substrate 2100 (as mentioned above, the base layer) and a second substrate 2200 (as mentioned above, the release film layer). At this time, the first substrate 2100 is guided by the traction mechanism 300 to travel to the winding column 1300 and be wound up, while the second substrate 2200 is guided to another downstream processing area for transmission. In one example of the traction process, the drive roller body 310 and the traction rubber roller 350 cooperate to clamp the first substrate 2100. The drive roller body 310 is driven to move the first substrate 2100, while the traction rubber roller 350 keeps the surface of the first substrate 2100 in contact with the surface of the drive roller body 310, thereby causing the corresponding first substrate 2100 to be pulled out.

[0122] In one embodiment of the detachable installation of the drive roller body 310, the end of the drive roller body 310 is mounted on the arrangement wall plate 320 via a quick-release mounting plate 330; a quick-release opening 321 is provided on the edge side of the arrangement wall plate 320; the quick-release mounting plate 330 is detachably mounted on the arrangement wall plate 320, and the side of the quick-release mounting plate 330 is engaged with the quick-release opening 321; the end of the drive roller body 310 is fixed to the corresponding side quick-release mounting plate 330. The drive roller body 310 can be detached by removing the quick-release mounting plate 330, and the entire drive roller body 310 can be removed outward from the quick-release opening 321. Specifically, the quick-release mounting plate 330 has a holding portion extending from the side near the arrangement wall plate 320, which is at least used to engage with the quick-release opening 321 for holding; and the holding portion can disengage through the opening side of the quick-release opening 321. The quick-release mounting plate 330 is provided with fixing holes, and the wall panel 320 is provided with corresponding mounting holes; while being snapped in place, the quick-release mounting plate 330 can be installed through the fixing holes and mounting holes using screws or other fasteners. The quick-release opening 321 is provided at the rear end of the wall panel 320, and the quick-release opening 321 opens to the rear; the quick-release mounting plates 330 on both sides are located on the same side relative to the wall panels 320 on both sides. For example, the quick-release mounting plates 330 can be detachably and fixedly installed on the left side of the wall panel 320, and the quick-release mounting plate 330 is snapped in place by the quick-release opening 321 of the corresponding wall panel 320 on the right side.

[0123] In the locking structure, the quick-release mounting plate 330 has a protruding structure 331 on the side near the quick-release opening 321, and the outer periphery of the protruding structure 331 matches the inner shape of the quick-release opening 321. The quick-release opening 321 is U-shaped, and the protruding structure 331 is circular. The quick-release mounting plate 330 is locked in place by the cylindrical protruding structure 331 engaging with the inner side of the U-shaped quick-release opening 321 on the corresponding wall panel 320.

[0124] To further improve the installation stability of the structure, the traction mechanism 300 in this embodiment also includes a limiting top block 322, which is used to prevent the quick-release mounting plate 330 from detaching from the opening side of the quick-release opening 321. Specifically, the limiting top block 322 is detachably installed on the opening side of the quick-release opening 321, and the limiting top block 322 extends to form a blocking and limiting part on the side near the quick-release mounting plate 330; and limiting top blocks 322 are provided above and below the quick-release opening 321.

[0125] In the specific drive mechanism, the drive roller body 310 is driven to rotate by the traction drive motor 340, which is mounted on the arrangement wall panel 320 via a quick-release mounting plate 330. The traction drive motor 340 is fixed to the side of the corresponding quick-release mounting plate 330 away from the quick-release opening 321. The quick-release mounting plate 330 has mounting holes, and the motor shaft of the traction drive motor 340 is connected to the end of the corresponding drive roller body 310 via the mounting holes. When the quick-release mounting plate 330 has a circular protrusion structure 331, the mounting hole is located in the center of the circular protrusion. One end of the drive roller body 310 is connected to the traction drive motor 340, and the other end of the drive roller body 310 is connected to a drive roller bearing seat 311, which is fixed to the corresponding quick-release mounting plate 330. The drive roller bearing seat 311 is fixed to the side of the corresponding quick-release mounting plate 330 away from the quick-release opening 321. The drive roller body 310 is connected to the end of the traction drive motor 340 and is also provided with an auxiliary bearing seat 312 and a vertical bearing 313. The auxiliary bearing seat 312 is fixed to the side of the wall plate 320 on this side, away from the traction drive motor 340. The vertical bearing 313 is installed above the auxiliary bearing seat 312 and is installed in conjunction with the corresponding end of the drive roller. At this time, the drive roller body 310 can be driven by the traction drive motor 340 at one end, and rotates in conjunction with the auxiliary bearing seat 312 and drive roller bearing seat 311 arranged at both ends.

[0126] To further enhance the relative independence of assembly and disassembly, a perforated operating area 323 is provided on the front side of the wall panel 320; multiple fixing holes are provided at the front end of the perforated operating area 323; and an auxiliary positioning plate 324 extends to the side from the front end of the perforated operating area 323. That is, the wall panel 320 is a detachable wall panel, which can be installed and removed from the main wall panel 1120 of the mating structure, meaning the overall traction mechanism 300 is detachable. Furthermore, to strengthen and fix the overall structure of the traction mechanism 300, one or more fixing rods 360 are provided between the two wall panels 320. In this embodiment, at least two diagonally opposite fixing rods 360 are fixed.

[0127] In this embodiment, the end of the traction roller 350 is mounted on the arrangement wall panel 320 via a guide drive mechanism 351. The guide drive mechanism 351 includes a traction guide rail fixed to the arrangement wall panel 320, a traction cylinder, and a traction slider that moves on the traction guide rail driven by the traction cylinder. In this embodiment, the direction of the traction guide rail can be vertical. The end of the corresponding traction roller 350 is connected to the traction slider. During the traction process, the guide drive mechanism 351 drives the traction roller 350 to move (including moving away from or towards the drive roller body 310), thereby cooperating to achieve the support and traction of the material. When it is necessary to stop conveying and release the film material, it can move away from the drive roller body 310.

[0128] like Figures 15-17 As shown, the unwinding and take-up integrated device 1000 in this embodiment also includes a floating roller device 400 on the side of the unwinding column 1200. The floating roller device 400 includes a floating roller mounting main board 410, a floating roller drive mechanism 450, a floating roller body 420, and a counterweight assembly 440. The floating roller mounting main board 410 is rotatably mounted on the main wall plate 1120. The floating roller drive mechanism 450 drives the floating roller mounting main board 410 to rotate. The end of the floating roller body 420 is mounted on one side of the rotation center of the floating roller mounting main board 410, and the counterweight assembly 440 is located on the other side of the rotation center of the floating roller mounting main board 410. The floating roller drive mechanism 450 drives the floating roller mounting main board 410 to rotate, thereby causing the floating roller body 420 to swing around the rotation center as the swing base point. The counterweight assembly 440 is located on the opposite side of the floating roller body 420 and performs counterweight balance based on the weight of the floating roller body 420.

[0129] In this embodiment, the counterweight assembly 440 includes a counterweight rod 441 and a weight 442 mounted on the counterweight rod 441. The counterweight rod 441 is mounted on the side of the floating roller mounting main plate 410 opposite to the floating roller body 420, and the weight 442 is detachably sleeved on the counterweight rod 441. The weight of the counterweight rod 441 is less than the weight of the floating roller body 420.

[0130] In this embodiment, to ensure the tension adjustment effect of the floating roller, the ratio of the distance D1 between the rotation center of the floating roller mounting plate 410 and the floating roller body 420 to the distance D2 between the rotation center and the counterweight assembly 440 is greater than 1.3, and the distance from the rotation center to the counterweight assembly 440 is less than the distance from the rotation center to the floating roller body 420. More specifically, the ratio D1:D2 of the distance between the rotation center and the floating roller body 420 and the distance between the rotation center and the mounting assembly is 1.5 to 3. When the counterweight assembly 440 is a counterweight rod 441, the distance between the rotation center and the counterweight assembly 440 represents the distance between the rotation center and the counterweight rod 441. In this embodiment, the swing angle range of the floating roller body 420 relative to the horizontal plane is -30° to 30°, that is, the rotation angle range of the rotation center is 60°.

[0131] To ensure the adjustability of the floating roller's oscillation and limit its range, in this embodiment, the main wall panel 1120 is provided with limit blocks 401 above and below the side of the floating roller mounting main board 410 where the counterweight assembly 440 is arranged. Simultaneously, corresponding anti-collision pads 412 are installed at the upper and lower ends of the side of the floating roller mounting main board 410 where the counterweight assembly 440 is arranged, and the anti-collision pads 412 are configured in conjunction with the limit blocks 401.

[0132] In this embodiment, the floating roller device 400 further includes a rotating shaft 430, which passes through the floating roller mounting main plate 410 and is mounted on the corresponding side main wall plate 1120. The rotating shaft 430 forms the rotation center of the floating roller mounting main plate 410. When the drive mechanism drives the floating roller mounting main plate 410 to rotate, the floating roller mounting main plate 410 rotates around the rotating shaft 430. The side of the floating roller mounting main plate 410 near the floating roller body 420 forms a swing arm, causing the floating roller body 420 to swing. The counterweight assembly 440 is located on the side of the floating roller mounting main plate 410 opposite to the floating roller body 420, at least balancing the weight of the floating roller body 420.

[0133] The floating roller drive mechanism 450 includes a floating roller telescopic cylinder 451, which is mounted on the main wall panel 1120. The floating roller mounting main plate 410 extends upward to form a connecting portion 411, and the connecting portion 411 is located between the floating roller body 420 and the rotating shaft 430 along the length of the floating roller mounting main plate 410. The output end of the floating roller telescopic cylinder 451 is rotatably connected to the connecting portion 411 at the upper end of the floating roller main plate. To adapt to the substrate, the floating roller body 420 can be a rubber roller with an elastic surface.

[0134] In addition, to improve the adjustability of the floating roller's position, the floating roller mounting main plate 410 is also provided with a mounting groove (not shown). The mounting groove has multiple mounting positions, and the end of the counterweight rod 441 is adjustablely mounted in the mounting groove. The mounting groove can be a long strip-shaped mounting groove, with its length direction parallel to the length direction of the floating roller mounting main plate 410. A locking screw is connected to the end of the counterweight rod 441, which engages to lock the position of the counterweight rod 441 relative to the mounting groove. Alternatively, it can be fixed using a locking structure. The end of the counterweight rod 441 is mounted in the mounting groove via the locking structure, which can release or tighten the end of the counterweight rod 441 on the corresponding side.

The unwinding column 1200 and the guide roller 1400 are installed between the two main wall panels 1120, and the winding column 1300 and the adaptive mechanism 100 are installed on the second correction mechanism 230. The first correction mechanism 220 is used at least to adjust the position of the unwinding column 1200 along its length, that is, the first correction mechanism 220 guides the unwinding column 1200 to move along its length. The second correction mechanism 230 is used at least to adjust the position of the winding column 1300 along its length, that is, the second correction mechanism 230 guides the winding column 1300 to move along its length. An offset detection sensor is also provided to detect whether the unwinding column 1200, the winding column 1300, or the position of the coiled material are offset. First, the first correction mechanism 220 is used to correct the alignment by moving the main structure, including the main wall panel 1120, unwinding column 1200, upper base plate 1130, second correction mechanism 230, and winding column 1300, to ensure the unwinding side is corrected to a suitable unwinding position, including a suitable position relative to other downstream transmission directions. Then, the second correction mechanism 230 is used to correct the alignment by moving the top structure, including the winding column 1300, to ensure the winding side is corrected to a suitable winding position. This results in stable unwinding and winding after correction.

[0136] As one implementation of the first correction mechanism 220 and the second correction mechanism 230, the first correction mechanism 220 includes a first guide component 221 and a lower base plate 222.

A plurality of reinforcing rods 203 are provided between the main wall panels 1120.

[0137] In the guiding mechanism, the first guiding component 221 is mounted on the base 1110 via a pad. The lower base plate 222 cooperates with the first guiding component 221 to form a guiding sliding structure. When the lower base plate 222 is driven by an external force, it can move relative to the base 1110 along the guiding direction of the first guiding component 221, correcting the unwinding column 1200 on the inner lower base plate 222 to a suitable position. Similarly, the top plate 232 cooperates with the second guiding component 231 to form a guiding sliding structure. When the top plate 232 is driven by an external force, it can move relative to the upper base plate 1130 along the guiding direction of the second guiding component 231, correcting the winding column 1300 on the top plate 232 to a suitable position. In this embodiment, in order to improve the guiding effect, multiple first guiding components 221 are arrayed between the lower base plate 222 and the base 1110, with corresponding first guiding components 221 arranged on the left and right sides, front and rear positions. Multiple second guide components 231 are arrayed between the top plate 232 and the upper base plate 1130, with corresponding second guide components 231 arranged on the left and right sides and at the front and rear positions.

[0138] In terms of the specific method of realizing the correction power, the first correction mechanism 220 also includes a first cylinder 220A. The lower base plate 222 has an installation opening. The first cylinder 220A is arranged on the base 1110 through the installation opening, and the output end of the first cylinder 220A is connected to the lower base plate 222. The first cylinder 220A drives the lower base plate 222 to move relative to the base 1110 on the first guide assembly 221. The direction of action of the first cylinder 220A, that is, the extension and retraction direction, is consistent with the guiding direction of the first guide assembly 221. The lower base plate 222 is moved by pushing or pulling outward with the output end of the first cylinder 220A. The second correction mechanism 230 also includes a second cylinder 230A. The second cylinder 230A is installed on one side of the upper base plate 1130, and the output end of the second cylinder 230A is connected to one side of the top plate 232. The second cylinder 230A drives the top plate 232 to move relative to the upper base plate 1130 on the second guide assembly 231. Similarly, the output end of the second cylinder 230A is connected to the side of the top plate 232. When the output end of the second cylinder 230A extends and retracts, it drives the top plate 232 along the guiding direction of the second guide assembly 231. In the specific arrangement, in this embodiment, the first cylinder 220A is arranged on the base 1110 through the mounting opening of the lower base plate 222, which facilitates the connection between the output end of the first cylinder 220A and the inner side of the mounting opening of the lower base plate 222; and the inner side of the mounting opening of the lower base plate 222 extends to form a mounting part, and the output end of the first cylinder 220A is fixedly connected to the mounting part. The second cylinder 230A is mounted on the side of the upper base plate 1130 through an L-shaped fixing seat; the output end of the second cylinder 230A is connected to the side of the top plate 232.

[0139] In this embodiment, three guide rollers 1400 are included. The ends of the guide rollers 1400 are mounted on corresponding side mounting surfaces via adjusting seats 201. The adjusting seat 201 includes an outer limiting protrusion 201A, an inner fixing block 201B, and fastening bolts. An adjustment gap is provided between the limiting protrusion 201A and the fixing block 201B. The end of the guide roller 1400 is mounted on the fixing block 201B, which has an elongated hole. The elongated hole, in conjunction with the fastening bolts, adjusts the position of the fixing block 201B inside the limiting protrusion 201A. When the guide rollers 1400 are installed between wall panels, the mounting surface is the wall panel surface, the limiting protrusion 201A is mounted on the wall panel, and the limiting protrusion 201A is located outside the fixing block 201B. The position of the end of the guide roller 1400 can be finely adjusted via the adjusting seat 201, thereby adjusting the parallel state of the guide rollers 1400, etc.

[0140] To facilitate positioning at frequently used locations, a positioning post 223 is provided on the lower base plate 222, and a corresponding positioning hole 224 is provided on the base 1110. The positioning post 223 sinks down and engages with the positioning hole 224 to position the relative position before or after correction. The positioning post 223 is a movable positioning post 223. When the lower base plate 222 moves to the position where the positioning post 223 engages with the positioning hole 224, the positioning post 223 sinks due to its own weight, thereby engaging with the positioning hole 224 to achieve the corresponding positioning.
