Abstract

This application relates to an adaptive tension adjustment mechanism and a winding / unwinding device. The adaptive tension adjustment mechanism includes: a roll body, a proximity pressure roller, a first drive mechanism, and a second drive mechanism. The proximity pressure roller is arranged adjacent to the roll body, and its end is mounted on the second drive mechanism. The first drive mechanism drives the second drive mechanism to move closer to or away from the roll body on the first drive mechanism, and the second drive mechanism drives the proximity pressure roller to move closer to or away from the roll body on the second drive mechanism. This tension adjustment mechanism can adaptively adjust the distance between the proximity pressure roller and the roll body, achieving tension adjustment on the roll body side within a limited length or space. It overcomes problems such as limited total stroke and difficulty in arrangement of tension adjustment mechanisms in a horizontally confined space, and is thus used in winding / unwinding devices.

Description

Technical Field

[0001] This application relates to the field of winding and unwinding technology, and more specifically, to an adaptive tension adjustment mechanism and winding and unwinding device. Background Technology

[0002] In traditional winding and unwinding processes, continuous tension adjustment is typically required to maintain a certain degree of stretch. One common method is adjustment using pressure rollers. For production lines with long lengths and sufficient space, adjustable pressure rollers can be installed, with the tension adjustment rollers positioned at a certain distance from the winding or unwinding area. This avoids situations where tension adjustment is difficult due to insufficient distance. However, for situations with limited space or short adjustment areas, the aforementioned common pressure roller structures are difficult to implement. Furthermore, because the thickness of the outer layer of the winding material changes during winding and unwinding, the angle and tension of the material passing through the pressure rollers also continuously change. Therefore, tension adjustment remains indispensable for winding and unwinding devices with limited width and space. The required tension adjustment structure must not only adapt to changes in the thickness of the winding and unwinding material to achieve tension adjustment but also be able to be arranged within a limited space.

[0003] Therefore, the industry urgently needs an adaptive tension adjustment mechanism that can adaptively adjust the tension of the roll material according to the thickness of the roll material under short spacing conditions, so as to coordinate with the corresponding winding or unwinding. Utility Model Content

[0004] Based on this, this application provides an adaptive tension adjustment mechanism suitable for scenarios with limited tension adjustment space, wherein the tension of the roll material can be continuously and adaptively adjusted according to the thickness of the roll material.

[0005] The technical solution adopted in this application is an adaptive tension adjustment mechanism, comprising: a roll body, a proximity pressure roller, a first drive mechanism and a second drive mechanism. The proximity pressure roller is arranged adjacent to the roll body, and the end of the proximity pressure roller is mounted on the second drive mechanism. The first drive mechanism drives the second drive mechanism to move closer to or away from the roll body on the first drive mechanism, and the second drive mechanism drives the proximity pressure roller to move closer to or away from the roll body on the second drive mechanism.

[0006] 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 cylinder to adjust the corresponding lateral tension. Specifically, when the thickness of the roll changes, the distance between the proximity pressure roller and the outer surface of the roll 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 roll 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 roll tension on one side of the roll. 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, which is suitable for scenarios with limited tension adjustment space.

[0007] Understandably, the roll body includes a roll spool. Further, the roll body is a roll spool or formed from a roll spool and its outer roll material. Even further, the roll material includes at least a flexible substrate to be unwound or rewound.

[0008] In one embodiment, the roll shaft is a take-up shaft. When space is limited such that the maximum arrangement distance between the approach pressure roller and the take-up shaft is less than or equal to a certain range (e.g., 1m), after the substrate is taken up by the approach pressure roller, it reaches the roll column. At this time, as the thickness of the roll column increases, the approach pressure roller needs to adjust the substrate winding angle and substrate tension within the limited adjustment space. Therefore, it needs to adaptively move the approach pressure roller away from the roll column and maintain a stable preset distance. The approach pressure roller is moved outward by the second drive mechanism. At the same time, if the second drive mechanism cannot continue to drive the approach pressure roller closer to or away from the roll column, the distance between the approach pressure roller and the outer surface of the roll column is greater than the preset distance. At this time, the first drive mechanism can be executed again to move towards the roll column to correct the distance. Similarly, the second drive mechanism can also further drive the approach pressure roller when the first drive mechanism can no longer drive it closer to or away from the roll column, and the distance can be corrected again by the first drive mechanism. As can be seen, by using the first drive mechanism alone, or the second drive mechanism alone, or by driving both in the same and / or opposite directions more than once, the proximity roller can continuously maintain a preset distance from the coil during the operation of the coil, adapting to changes in the thickness of the coil and thus achieving stable tension control. That is, the adaptive tension adjustment mechanism described in this application can adaptively adjust the distance between the proximity roller and the coil, achieving tension adjustment on the coil side within a limited length or space. Furthermore, the required components are simple in structure and easy to assemble and manufacture. The corresponding drive mechanism arrangement can be achieved using longitudinal space, and through the cooperation of the first and second drive mechanisms, it can quickly adjust and correct to the preset distance, adaptively adjusting to changes in the coil thickness while ensuring adjustment accuracy. The tension adjustment mechanism described in this application has a significant adaptive tension adjustment effect and can achieve stable tension control on the coil side.

[0009] In one embodiment, the first and second drive mechanisms near both sides of the pressure roller are symmetrically arranged, which is more conducive to tension adjustment.

[0010] 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.

[0011] In one embodiment, the first power mechanism is an electric motor.

[0012] In one embodiment, the rack is fixedly installed on the side of the transfer base plate and arranged along the length of the transfer base plate.

[0013] 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.

[0014] 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 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. Thus, the first and second drive mechanisms can achieve relatively independent pressure roller driving, and the first and second drive mechanisms can cooperate to move in the same or opposite directions, realizing a complex pressure roller adjustment process.

[0015] In one embodiment, the second power mechanism is a cylinder.

[0016] In one embodiment, the adaptive tension adjustment mechanism further includes a transfer roller, which is arranged adjacent to the proximity pressure roller. 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.

[0017] In one embodiment, the transfer roller is arranged in a direction away from the coil, the approach pressure roller is located between the coil and the transfer roller, and the end of the transfer roller is fixedly connected to the first drive mechanism. The first drive mechanism drives the transfer roller to approach or move away from the coil on the first drive mechanism.

[0018] In one embodiment, the end of the transfer roller is mounted on the transfer base plate via a transfer roller bracket and is located near the side of the approach pressure roller.

[0019] In one embodiment, the end of the transfer roller is mounted on the transfer roller bracket via an adjusting seat; the adjusting seat includes a limiting protrusion, a fixing block, and a fixing block bolt, the limiting protrusion being located outside the fixing block, and an adjusting gap being left between the limiting protrusion and the fixing block; the roller body end of the transfer roller is mounted on the fixing block, and the fixing block is provided with a fine-tuning elongated hole, the fine-tuning elongated hole cooperating with the fixing block bolt to adjust the position of the fixing block inside the limiting protrusion.

[0020] In one embodiment, the adaptive tension adjustment mechanism further includes a detection unit for detecting the distance between the proximity pressure roller and the outer surface of the roll column, or detecting the tension of the substrate to be wound on the roll column during the winding process, or detecting the tension of the substrate to be unwound on the roll column during the unwinding process. The detection unit can directly or indirectly measure the distance between the proximity pressure roller and the outer surface of the roll column, or the real-time tension during the winding or unwinding process, and feed this information back to the first and second drive mechanisms to make corresponding reciprocating adjustments, so that the actual distance between the proximity pressure roller and the outer surface of the roll column is adjusted to a preset distance, and continuous detection and adjustment are performed.

[0021] In one embodiment, the detection unit is electrically connected to the first drive mechanism.

[0022] In one embodiment, the detection unit is electrically connected to the second drive mechanism.

[0023] In one embodiment, the detection unit is disposed on the first drive mechanism, or on the second drive mechanism, or on the end side near the pressure roller, or on the mounting surface of the first drive mechanism.

[0024] Another objective of this application is to provide a winding / unwinding device that includes the adaptive tension adjustment mechanism described above. This winding / unwinding device also possesses the advantages of the adaptive tension adjustment mechanism described above, such as the ability to adaptively adjust the distance between the pressure roller and the roll body, achieving tension adjustment on the roll body side within a limited length or space, ensuring both accuracy and timeliness of adjustment, and completing winding / unwinding or integrated winding / unwinding operations, while also having a lower cost.

[0025] This application includes at least the following beneficial effects: The adaptive tension adjustment mechanism described in this application can adaptively adjust the distance between the pressure roller and the coil body, and realize the tension adjustment on the side of the coil body within a limited length or space; and the required component structure is simple, easy to assemble and manufacture, and can utilize the longitudinal space to realize the corresponding drive mechanism arrangement, requiring a narrow space, overcoming the problems of limited total stroke and difficulty in arrangement of the tension adjustment mechanism in a limited horizontal space, and facilitating the formation of an independent adjustment process for the pressure roller through tension isolation, and simplifying the tension adjustment process by continuously maintaining the preset distance.

[0041] During the winding and unwinding process, the thickness of the outer layer of the winding and unwinding roll changes, and the angle and tension of the winding and unwinding roll passing through the pressure rollers also change continuously. For winding and unwinding devices with limited width and small space, the required tension adjustment structure must not only be able to adapt to the changes in the thickness of the winding and unwinding roll to achieve tension adjustment, but also be able to be arranged in a narrow and limited space. There are currently no relevant reports.

[0042] Based on this, this application provides an adaptive tension adjustment mechanism suitable for scenarios with limited tension adjustment space, wherein the tension of the roll material can be continuously and adaptively adjusted according to the thickness of the roll material.

[0043] See Figures 1-6 One embodiment of this application provides an adaptive tension adjustment mechanism 100A, including: a roll column (wound column or unwound column) 1300, a proximity pressure roller 110, a first drive mechanism 120 and a second drive mechanism 130. The proximity pressure roller 110 is arranged adjacent to the roll column 1300, and the end of the proximity pressure roller 110 is mounted on the second drive mechanism 130. The first drive mechanism 120 drives the second drive mechanism 130 to approach or move away from the roll column 1300 on the first drive mechanism 120, and the second drive mechanism 130 drives the proximity pressure roller 110 to approach or move away from the roll column 1300 on the second drive mechanism 130.

[0044] The first drive mechanism 120 and the second drive mechanism 130 of this application can be used individually or in combination to adaptively adjust the distance between the proximity roller 110 and the outer surface of the roll 1300 to adjust the corresponding lateral tension. Specifically, when the thickness of the roll 1300 changes, the distance between the proximity roller 110 and the outer surface of the roll 1300 changes. The first drive mechanism 120 can be used alone, the second drive mechanism 130 can be used alone, or the first drive mechanism 120 and the second drive mechanism 130 can be used in combination to move the proximity roller 110, so that the proximity roller 110 and the outer surface of the roll 1300 accurately maintain a stable preset distance or preset distance range (understandably, when an allowable error exists, the preset distance range is the preset distance ± error), thereby controlling the tension of the roll (substrate) on one side of the roll 1300. Furthermore, the first drive mechanism 120 and the second drive mechanism 130 can be arranged in a narrow space, and can work together to achieve a total stroke greater than the stroke of the first drive mechanism 120 or the second drive mechanism 130, which is suitable for scenarios with limited tension adjustment space.

[0045] Understandably, the roll column 1300 includes a roll spool. Further, the roll column 1300 is a roll spool, or is formed by a roll spool and its outer roll material (not shown in the figure). Even further, the roll material includes at least a flexible substrate (such as a release film) to be unwound or rewound. Taking the roll column 1300 as a rewinding column as an example, it includes a rewind spool. When the rewind spool is covered with a roll material substrate, the rewinding column is formed by the rewind spool and its outer roll material substrate. When the rewind spool does not have an outer roll material substrate, the rewinding column is simply the rewind spool.

[0046] Furthermore, taking winding as an example, when space constraints prevent the maximum spacing between the approach pressure roller 110 and the winding shaft from being less than or equal to a certain range (e.g., 1m), after the substrate passes through the approach pressure roller 110 to the roll column 1300 and winding begins, as the thickness of the roll column 1300 increases, the approach pressure roller 110 needs to adjust the substrate winding angle and substrate tension within a limited adjustment space. Therefore, it needs to adaptively move the approach pressure roller 110 away from the roll column 1300 while maintaining a stable preset spacing. The second drive mechanism 130 is used to move the approach pressure roller 110... 10 moves outward. Simultaneously, if the second drive mechanism 130 can no longer drive the approach roller 110 closer to or further away from the coil 1300, and the distance between the approach roller 110 and the outer surface of the coil 1300 is greater than a preset distance, the first drive mechanism 120 can be moved again towards the coil 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 can again be corrected by the first drive mechanism 120. Therefore, by using the first drive mechanism 120 alone, or the second drive mechanism 130 alone, or both in one or more unidirectional and / or reverse directions, the approach roller 110 can continuously maintain a preset distance from the coil 1300 during the operation of the coil 1300, adapting to changes in the thickness of the coil 1300, thereby achieving stable tension control. The adaptive tension adjustment mechanism 100A of this application can adaptively adjust the distance between the pressure roller 110 and the coil 1300, achieving tension adjustment on the coil 1300 side within a limited length or space. Furthermore, the required component structures are simple, facilitating assembly and manufacturing. Additionally, the corresponding drive mechanism arrangement can be implemented using longitudinal space, and through the cooperation of the first drive mechanism 120 and the second drive mechanism 130, it can quickly adjust and correct to a preset distance, adaptively adjusting to follow the thickness changes of the coil 1300 while ensuring adjustment accuracy. This tension adjustment mechanism 100A exhibits significant adaptive tension adjustment effect, achieving stable tension control on the coil 1300 side.

[0047] In one embodiment, the first drive mechanism 120 and the second drive mechanism 130, which are close to both sides of the pressure roller 110, are symmetrically arranged, which is more conducive to adjusting the tension.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] In one embodiment, the adaptive tension adjustment mechanism 100A further 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, further improving the accuracy and effectiveness of tension adjustment.

[0055] In one embodiment, the transfer roller 140 is arranged in a direction away from the coil 1300, and the approach roller 110 is located between the coil 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 coil 1300 on the first drive mechanism 120.

[0056] Taking the coiled material column 1300 as an example, the substrate is wound up above the transfer roller 140, near the pressure roller 110, and above the coiled material column 1300. The transfer roller 140 effectively guides the upstream substrate to the coiled material column 1300, forming a tension adjustment area between the transfer roller 140 and the coiled material 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 to move closer to or further away from the coiled material column 130 synchronously with the second drive mechanism 130. The transfer roller 140 moves under the drive of the first drive mechanism 120. Furthermore, when the coil column 1300 is a take-up column, the upper surface of the coil 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.

[0057] 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 coil 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.

[0058] 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 position of the end 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.

[0059] In one embodiment, the adaptive tension adjustment mechanism further includes a detection unit (not shown) for detecting the distance between the proximity pressure roller 110 and the outer surface of the roll column 1300, or detecting the tension of the substrate to be wound on the roll column 1300 during the winding process, or detecting the tension of the substrate to be unwound on the roll column 1300 during the unwinding process. The detection unit can directly or indirectly measure the distance between the proximity pressure roller 110 and the outer surface of the roll column 1300, or the real-time tension during the winding or unwinding process. This information is then fed back to the first drive mechanism 120 and the second drive mechanism 130 to make corresponding reciprocating adjustments, so that the actual distance between the proximity pressure roller 110 and the outer surface of the roll column 1300 is adjusted to a preset distance, and continuous detection and adjustment are performed.

[0060] In one embodiment, the detection unit is electrically connected to the first drive mechanism 120 and the second drive mechanism 130.

[0061] 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.

[0062] Another objective of this application is to provide a winding and unwinding device (not shown in the figure) that includes the aforementioned adaptive tension adjustment mechanism 100A. Understandably, this winding and unwinding device also has the advantages of the aforementioned adaptive tension adjustment mechanism 100A, such as being able to adaptively adjust the distance between the pressure roller and the roll body, achieving tension adjustment on the roll body side within a limited length or space, ensuring the accuracy and timeliness of the adjustment, and completing winding or unwinding or integrated winding and unwinding operations, while having a low cost.

[0063] Understandably, other structural features of the winding and unwinding device can be existing technologies, and those skilled in the art can supplement the structural features of the winding and unwinding device as needed when implementing this application.

[0064] 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.

[0065] Example 1

[0066] like Figures 1-6As shown, this embodiment discloses an adaptive tension adjustment mechanism 100A, including a roll column 1300, a proximity roller 110, a first drive mechanism 120, and a second drive mechanism 130. The roll column 1300 is formed from the roll substrate on the roll shaft and the outer roll shaft. The proximity roller 110 is arranged adjacent to the roll column 1300, and its end is mounted on the second drive mechanism 130. The first drive mechanism 120 drives the second drive mechanism 130 to move closer to or away from the roll column 1300 on the first drive mechanism 120, and the second drive mechanism 130 drives the proximity roller 110 to move closer to or away from the roll shaft 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 proximity roller 110 are symmetrically arranged. The roll column 1300 is a take-up column, comprising a roll shaft or a roll shaft and an outer roll material. The roll material includes a flexible substrate to be wound. Understandably, when there is no outer roll material substrate on the take-up shaft, the roll column 1300 then functions as the take-up shaft. When the thickness of the roll column 1300 changes, the first drive mechanism 120 and the second drive mechanism 130 cooperate to move the approach pressure roller 110, so that the approach pressure roller 110 and the outer surface of the roll column 1300 maintain a precise and stable preset distance or preset distance range (when an allowable error exists, the preset distance range is the preset distance ± error), thereby controlling the tension of the roll material substrate on one side of the roll column 1300.

[0067] The first drive mechanism 120 and the second drive mechanism 130 are arranged in a narrow space to cooperate and achieve a total stroke greater than the stroke of either the first drive mechanism 120 or the second drive mechanism 130. In specific adjustment processes, for example, when space is limited and the maximum arrangement distance between the approach pressure roller 110 and the take-up shaft is less than or equal to 1m, the tension of the substrate can be adjusted by using the distance between the approach pressure roller 110 and the roll column 1300. After the substrate passes through the approach pressure roller 110 to the roll column 1300, as the thickness of the roll column 1300 increases, and the approach pressure roller 110 needs to adjust the substrate take-up angle and substrate tension within the limited adjustment space, it needs to adaptively move the approach pressure roller 110 away from the roll column 1300 while maintaining a stable preset distance. The second drive mechanism 130 moves the approach pressure roller 110 outward. Simultaneously, if the second drive mechanism 130 drives the approach pressure roller 110, causing the distance L1 between the approach pressure roller 110 and the outer surface of the coil 1300 to exceed the preset distance L0, the first drive mechanism 120 can be executed again to move it closer to the coil 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 correct this through the first drive mechanism 120. Through one or more simultaneous or opposite drives by the first drive mechanism 120 and the second drive mechanism 130, the approach pressure roller 110 can continuously maintain the preset distance from the coil 1300 during operation, adapting to changes in the thickness of the coil 1300 and achieving stable tension control.

[0068] like Figure 2 , 3As shown, 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. 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. 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 connected 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 drive the pressure roller 110 connected to 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, in this embodiment, the first power mechanism 121 is a motor, and the second power mechanism 131 is 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.

[0069] 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.

[0070] like Figures 1-6As shown, in order to form a relatively independent tension adjustment area on the winding side and improve the adjustment effect of the proximity pressure roller 110, in this embodiment, the adaptive tension adjustment mechanism 100A also includes a transfer roller 140 adjacent to the proximity pressure roller 110. The proximity pressure roller 110 is located between the roll 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 proximity pressure roller 110 through the 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 roll column 1300 on the first drive mechanism 120. When the roll column 1300 is a winding column, the substrate is wound up from above the transfer roller 140 and below the proximity pressure roller 110 to above the winding column. The upper surface of the roll 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 bracket 141 has a bent structure, and the upper part of the transfer roller bracket 141 extends away from the roll 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.

[0071] Specifically, such as Figure 4 As shown, 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 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 a fine-tuning elongated hole. The fine-tuning elongated hole, in conjunction with the fixing block bolt, adjusts the position of the fixing block 201B inside the limiting protrusion 201A. By tightening or loosening the fixing block bolt to adjust the position of the fixing block 201B relative to the inner side of the limiting protrusion 201A, the position of the end of the transfer roller 140 can be finely adjusted.

[0072] The adaptive tension adjustment mechanism 100A in this embodiment also includes a detection unit (not shown in the figure) for detecting the distance between the approach pressure roller 110 and the outer surface of the coiled material column 1300. Specifically, in this embodiment, the detection unit is electrically connected to both the first drive mechanism 120 and the second drive mechanism 130. By detecting the distance between the approach pressure roller 110 and the coiled material column 1300 through the detection unit, feedback is sent to the first drive mechanism 120 and the second drive mechanism 130 to achieve corresponding reciprocating adjustment. Specifically, in this embodiment, one detection unit is arranged on the first drive mechanism 120, and another detection unit is arranged on the end side of the approach pressure roller 110.
