Description

Technical Field

[0001] This utility model relates to the field of roller pressing equipment technology, specifically to a pressure roller pressure regulating device and sheet material conveying equipment based on pressure detection. Background Technology

[0002] During the sheet material transport process, multiple rollers are usually required to support the electrode sheet material, control its tension, and adjust its angle so that the sheet material can travel along a preset path.

[0003] Because sheet material production demands are diverse, various scenarios during production require adjustments to sheet material tension. These scenarios include providing different tensions for different sheet material specifications, adjusting output tension to address belt conveyor malfunctions, and providing different tension outputs or inputs for different processing modules. Current related technologies typically adjust tension via rollers, such as changing the roller gap or adjusting the power output of the roller drive. While these methods can adjust roller tension, they directly modify the rollers, resulting in large adjustment ranges and a lack of precise fine-tuning. Utility Model Content

[0004] Therefore, this utility model aims to solve the problem that existing sheet material production and conveying tools directly adjust the sheet material tension through adjusting rollers, resulting in excessive adjustment range and inability to perform precise fine-tuning. In this way, it provides a pressure roller pressure adjustment device and sheet material conveying equipment based on pressure detection.

[0006] Furthermore, the torque transmission structure has a first connecting seat located in its middle on the first side, the first connecting seat being adapted to connect the pressure roller shaft, and the pressure sensor being located between the pressure roller and the first connecting seat.

[0010] Furthermore, the end of the second lever arm is provided with a fixing component that abuts against the inclined surface of the wedge block.

[0011] Furthermore, the first pressure output structure is a drive cylinder; the second pressure output structure is a screw drive structure, including an adjustment seat suitable for mounting on the frame, an adjustment screw connected to the adjustment seat, and the wedge block is helically connected to the adjustment screw.

[0025] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] A sheet material conveying device includes a drive roller, a driven roller 18, and a pressure-detection-based pressure regulating device. The pressure-detection-based pressure regulating device is connected to the roller shafts at opposite ends of the driven roller 18. The pressure-detection-based pressure regulating device is adapted to drive the driven roller 18 closer to or further away from the drive roller. Specifically, a pressure-detection-based pressure regulating device is installed at each opposite end of the driven roller shaft.

[0027] like Figure 1 , Figure 2 The pressure regulating device for a pressure roller based on pressure detection, shown, includes a torque transmission structure 1, a first pressure output structure 4, a second pressure output structure 5, a pressure sensor 10, and a main control module. The first side of the torque transmission structure 1 is adapted to be fixed to the roller shaft of the pressure roller along a first direction, including a first lever arm 2 and a second lever arm 3. The first pressure output structure 4 includes a drive cylinder 6 adapted to be mounted on a frame, and the first lever arm 2 is connected to the drive shaft of the drive cylinder 6. The second pressure output structure 5 is adapted to be fixedly mounted on the frame, including a wedge block 19 and a rotary drive member 7 adapted to drive the wedge block 19 to move along the first direction. The wedge block 19 has an inclined surface that abuts against the second lever arm 3 in a third direction. The pressure sensor 10 is connected to the torque transmission structure 1 and located between the torque transmission structure 1 and the roller shaft of the pressure roller, adapted to detect the pressure roller pressure. The main control module is electrically connected to the pressure sensor 10 and adapted to collect the pressure roller pressure through the pressure sensor 10.

[0028] This pressure roller pressure regulating device based on pressure detection can drive the torque transmission structure 1 to move along a first direction through the drive cylinder 6 of the first pressure output structure 4, thereby causing the torque transmission structure 1 to push the pressure roller to move along the first direction, thus changing the gap between the rollers and enabling rapid adjustment of the pressure roller tension. By adjusting the height position of the wedge block 19 of the second pressure output structure 5 on the rotating drive member 7, the height position of the second lever arm 3 abutting against the inclined surface of the wedge block 19 can be controlled, thereby enabling micro-drive of the torque transmission structure 1 along the first and second directions simultaneously, thereby causing the pressure roller to move micro-moves simultaneously along the first and second directions, realizing micro-adjustment of the gap between the rollers, which also realizes micro-adjustment of the pressure roller tension. By setting the electrically connected pressure sensor 10 and main control module, the accuracy of micro-adjustment of the pressure roller tension can be ensured.

[0029] In this embodiment, the first side of the torque transmission structure 1 is provided with a first connecting seat 8 suitable for connection to the roller shaft of the pressure roller, and the pressure sensor 10 is located between the pressure roller and the first connecting seat 8.

[0030] In this embodiment, the main control module is also electrically connected to the first pressure output structure 4 and the second pressure output structure 5, and is adapted to collect the pressure of the pressure sensor 10 and output it to the first pressure output structure 4 and the second pressure output structure 5. With this configuration, the driving amount of the first pressure output structure 4 and the second pressure output structure 5 can be adjusted in real time by the main control module according to the pressure value of the pressure sensor 10, thereby realizing real-time adjustment of the pressure roller position and improving the efficiency of micro-adjustment.

[0031] In this embodiment, as Figure 3 As shown, the drive shaft of the drive cylinder 6 is fixed with a first fixing member connected to the end of the first lever arm 2. Specifically, the first fixing member is a clamping structure 11 fixed to the drive shaft of the drive cylinder 6, and the clamping structure 11 is fixed to the end of the first lever arm 2 by bolts. Specifically, the drive cylinder 6 is a drive cylinder.

[0032] In this embodiment, a fixing component is fixedly installed at the end of the second lever arm 3. The fixing component includes a fixing block 12 fixedly installed on the side away from the second lever arm 3 and a rotating block 13 rotatably connected to the fixing block 12. The rotating block 13 abuts against the inclined surface of the wedge block 19. With this configuration, when the wedge block 19 moves up and down in the second direction, the rotating block 13 can rotate on the inclined surface of the wedge block 19, improving the smoothness of driving the torque transmission structure 1. In this embodiment, the second pressure output structure 5 is a screw-driven structure, including an adjustment seat 14 suitable for fixing to the frame and an adjustment screw 15 connected to the adjustment seat 14. The wedge block 19 is helically connected to the adjustment screw 15. Specifically, the adjustment seat 14 is provided with a size scale value 16, which facilitates observation of the adjustment value. Specifically, the fixing block 12 protrudes from the side wall of the second lever arm 3.

[0033] In this embodiment, the screw drive structure also includes a bolt knob 17 connected to the adjusting screw 15, which is suitable for manually adjusting the height of the wedge block 19 via the bolt knob 17. In an alternative embodiment, a rotary drive 7 is connected to the adjusting screw 15, and both the rotary drive 7 and the drive cylinder 6 are electrically connected to the main control module. With this configuration, the main control module can control the driving structure of the adjusting screw 15 and the drive cylinder, and in conjunction with the pressure output of the pressure sensor 10, the accuracy of fine-tuning the pressure roller can be improved.

[0034] In this embodiment, a second connecting seat 9 is provided on the first lever arm 2, located between the first connecting seat 8 and the first pressure output structure 4. The second connecting seat 9 is suitable for installation on the frame. With this arrangement, the stability of driving the driven roller 18 can be ensured by the pressure roller pressure adjustment device.

[0035] like Figure 1 , Figure 2As shown, specifically, the first direction is the horizontal X-axis, the second direction is the vertical Y-axis, and the third direction is the Z-axis.

[0036] In this embodiment, two L-shaped baffles 20 are also fixedly installed on the first connecting seat. The two L-shaped baffles 20 are respectively spaced apart on the upper and lower sides of the driven roller 18 and extend along the length of the driven roller 18. This arrangement can prevent people from touching the driven roller 18 and getting injured by the L-shaped baffles 20. At the same time, the L-shaped baffles 20 are spaced apart from the outer wall of the driven roller 18 to avoid the L-shaped baffles 20 from hindering the smooth operation of the driven roller 18.

[0037] In summary, this pressure roller pressure regulating device based on pressure detection can drive the torque transmission structure 1 to move along the first direction through the drive cylinder 6 of the first pressure output structure 4, thereby causing the torque transmission structure 1 to push the pressure roller to move along the first direction and change the gap between the rollers, thus enabling rapid adjustment of the pressure roller tension. By adjusting the height position of the wedge block 19 of the second pressure output structure 5 on the rotating drive member 7, and controlling the height position of the second lever arm 3 abutting against the inclined surface of the wedge block 19, the torque transmission structure 1 can be simultaneously driven slightly along the first and second directions, thereby causing the pressure roller to move slightly simultaneously along the first and second directions, achieving slight adjustment of the gap between the rollers, which also achieves slight adjustment of the pressure roller tension. By setting the electrically connected pressure sensor 10 and main control module, the accuracy of the slight adjustment of the pressure roller tension can be ensured.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
