Description

Technical Field

[0001] This utility model belongs to the technical field of roller pressing equipment, specifically relating to a roller system disassembly and assembly mechanism and roller pressing equipment. Background Technology

[0002] Roll forming equipment is one of the key pieces of equipment in the lithium battery manufacturing process. It can roll coated and dried electrode sheets to compact them to a specific thickness. Roll forming equipment mainly consists of rollers. When the electrode sheet is conveyed to the gap between two rollers, the pressure generated by the rollers squeezing against each other acts on the electrode sheet. The electrical paste particles in the electrode sheet are displaced and deformed to fill the gaps between the particles. The rollers play a role in increasing the compaction density of the electrode sheet.

[0003] During operation, rollers in roller pressing equipment often experience wear. To ensure the accuracy and thickness uniformity of the pressed electrodes, the rollers need to be disassembled and replaced periodically. The roller pressing equipment mainly includes a mounting bracket for the rollers. Bearing seats are located at both ends of the roller along its axial direction. The roller rotates on the bearing seats. A movable pad is installed between the mounting bracket and the bearing seats to assist in positioning the bearing seats. The movable pad is connected to the mounting bracket. When replacing the rollers, the movable pad must be removed before the bearing seats can be removed from the mounting bracket.

[0004] However, roll forming equipment usually has a large number of rolls. In order to save space in the roll forming equipment, the space for removing the movable pads between the rolls is small, which makes it inconvenient for operators to remove the rolls. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a roller assembly / disassembly mechanism and a roller pressing device. The tensioning structure moves the movable pad closer to or away from the bearing seat. The movable pad can press against or loosen the bearing seat. The disassembly process of the roller system does not require the removal of the movable pad, which helps to improve the convenience of the roller disassembly operation.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0007] In a first aspect, this utility model provides a roller system disassembly and assembly mechanism, including a gate with a disassembly and assembly hole, a bearing seat disposed in the disassembly and assembly hole, and a gap between the bearing seat and the inner wall of the disassembly and assembly hole; a movable pad disposed in the gap, the movable pad cooperating with the gate to press against or loosen the bearing seat; and a tensioning structure disposed on the gate, the tensioning structure pressing the movable pad against the bearing seat, or loosening the movable pad to move the movable pad away from the bearing seat.

[0008] In some implementations, the archway has a first through hole and a second through hole. The tensioning structure includes a clamping member for pressing against the movable pad. The clamping member passes through the first through hole and is detachably connected to the archway. The clamping member extends out of or into the first through hole to approach or move away from the movable pad. The structure also includes a locking member that passes through the second through hole and is detachably connected to the movable pad.

[0009] In some implementations, the clamping element includes a clamping rod that is threadedly connected to the archway within the first through hole. The clamping rod is screwed into or out of the first through hole to move closer to or further away from the movable pad.

[0010] In some implementations, the movable pad has a connecting hole, and the locking member is a locking rod. The locking rod includes a connecting end, which is threadedly connected to the movable pad in the connecting hole.

[0011] In some implementations, the locking rod is fitted with an anti-disengagement component at the connecting end, which prevents the locking rod from disengaging from the second through hole.

[0012] In some implementations, the anti-loosening component is a locking nut, which is threadedly connected to the connecting end.

[0013] In some implementations, the archway is provided with a fixed pad on the inner wall of the disassembly hole, the fixed pad and the movable pad are arranged opposite to each other, and the bearing seat is arranged between the fixed pad and the movable pad.

[0014] In some implementations, multiple movable pads are provided, and the tensioning structure is provided corresponding to each movable pad.

[0015] In some implementations, the archway is equipped with an adjustment assembly for raising and lowering the bearing seat.

[0016] Secondly, this utility model provides a roller pressing device, including the roller assembly and disassembly mechanism described above.

[0017] In summary, this utility model has at least the following advantages:

[0018] 1. The roller assembly / disassembly mechanism provided by this utility model allows for the installation of the bearing housing. When the bearing housing is installed, it is placed into the disassembly / disassembly hole, and the movable pad is placed in the gap. The tightening structure presses the movable pad against the bearing housing, and the movable pad, together with the bracket, presses against the bearing housing, thus assisting in positioning the bearing housing. When the bearing housing is disassembled, the tightening structure releases the movable pad, allowing it to move in the gap and away from the bearing housing. The roller system can be easily disassembled without removing the movable pad, which improves the ease of operation.

[0019] 2. The roller pressing equipment provided by this utility model can save the space required for the disassembly and assembly of the roller system, reduce the problem of inconvenience caused by the difficulty in removing the movable pad due to narrow space, and facilitate the compact and reasonable spatial layout of the roller system.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Example 1:

[0031] Please see the appendix Figure 1 The roller assembly and disassembly mechanism of this utility model can be used in roller system 81 equipment, such as roller press, roller press and slitting integrated machine, coating machine or electrode take-up and unwinding device, etc. The roller system assembly and disassembly mechanism of this utility model makes the disassembly and disassembly of roller system 81 convenient and can reserve enough space for the disassembly and disassembly of roller system 81 without removing the movable pad 2.

[0032] The roller assembly / disassembly mechanism of this utility model includes a gate 1, which is specifically vertically arranged. The gate 1 has an assembly / disassembly hole 11 for placing the bearing seat 8. When the roller system 81 is installed, the bearing seat 8 is placed into the assembly / disassembly hole 11. A gap 111 is provided between the bearing seat 8 and the inner wall of the assembly / disassembly hole 11. Specifically, the gap 111 can be set at one end of the bearing seat 8 in the X-axis direction.

[0033] The archway 1 has a movable pad 2 installed in the gap 111. The movable pad 2 is specifically installed vertically on the long plate. The movable pad 2 and the archway 1 cooperate with each other to tighten or loosen the bearing seat 8.

[0034] The archway 1 is equipped with a tensioning structure 3. When installing the bearing seat 8, the bearing seat 8 is located between the movable pad 2 and the inner wall of the archway 1. The tensioning structure 3 presses the movable pad 2 against the bearing seat 8, and the movable pad 2 abuts against the corresponding side of the bearing seat 8, cooperating with the archway 1 to clamp the bearing seat 8, thus positioning the bearing seat 8. When disassembling the bearing seat 8, the tensioning structure 3 loosens the movable pad 2, allowing the movable pad 2 to move within the gap 111. The movable pad 2 can move along the X-axis and away from the bearing seat 8, and the bearing seat 8 can be removed from the archway 1 by the operator.

[0035] Compared with the traditional roller system disassembly and assembly structure, when disassembling the roller system 81, it is not necessary to first remove the movable pad 2. The loosening and tightening structure 3 can make the movable pad 2 press against or loosen the bearing seat 8. When the movable pad 2 loosens the bearing seat 8, it can provide enough space for the disassembly operation of the bearing seat 8, which helps to improve the convenience of the disassembly operation of the roller system 81.

[0036] Example 2:

[0037] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the elastic / tightening structure 3 of this utility model. Please refer to [link / reference]. Figures 2-4 .

[0038] Please see Figure 2In this embodiment, the archway 1 is provided with a first through hole 12. Specifically, the first through hole 12 is a horizontally arranged circular channel. The tensioning structure 3 includes a pressing member 31 for pressing against the movable pad 2. The pressing member 31 passes through the first through hole 12 and is detachably connected to the archway 1. The pressing member 31 extends or enters the first through hole 12 to approach or move away from the movable pad 2.

[0039] When the clamping member 31 extends out of the first through hole 12, the clamping member 31 can press against the surface of the movable pad 2 and press the movable pad 2 against the bearing seat 8. The movable pad 2 cooperates with the archway 1 to clamp the bearing seat 8. When the clamping member 31 enters the first through hole 12, the clamping member 31 releases the movable pad 2 and leaves the movable pad 2.

[0040] In a preferred embodiment, the clamping member 31 includes a clamping rod. As shown in some specific embodiments, the clamping rod may be a threaded rod. The clamping rod is threadedly connected to the inner wall of the first through hole 12. By screwing the clamping rod in or out, the clamping rod can be adjusted to move closer to or further away from the movable pad 2. Specifically, a first threaded hole is provided at the end of the clamping rod away from the movable pad 2. The operator can use a wrench to turn the clamping rod at the first threaded hole. When the clamping rod is screwed out of the first through hole 12 and presses the movable pad 2 against the bearing seat 8, the movable pad 2 cooperates with the arch 1 to clamp the bearing seat 8. When the clamping rod is screwed into the first through hole 12, the clamping rod releases the movable pad 2, and the movable pad 2 can move within the gap 111 and move away from the bearing seat 8.

[0041] Furthermore, multiple clamping rods can be provided. For example, in this embodiment, two clamping rods are provided. Multiple clamping rods help to enhance the clamping force of the movable pad 2 on the bearing seat 8, thereby improving the stability of the bearing seat 8 installation. It is understood that this is not a specific limitation on the number of clamping rods, and those skilled in the art can make adjustments based on this.

[0042] In some other specific embodiments, the clamping member 31 includes a rotating end, and a first threaded hole is opened at the rotating end. The clamping member 31 is only threadedly connected to the inner wall of the first through hole 12 at the rotating end, which is beneficial to improve the smoothness and convenience of adjusting the clamping member 31.

[0043] Please see Figures 2-4 The archway 1 has a second through hole 13, which is parallel to the first through hole 12. A locking member 32 is installed within the second through hole 13, and the locking member 32 is detachably connected to the movable pad 2 within the second through hole 13. In a preferred embodiment, the movable pad 2 has a connecting hole 21, which can be a threaded hole. The locking member 32 is a locking rod 321, which includes a connecting end 3211, which is threadedly connected to the movable pad 2 within the connecting hole 21.

[0044] In some specific embodiments shown, the archway 1 has a receiving groove 14, which is connected to the second through hole 13. The connecting end 3211 passes through the second through hole 13 and the receiving groove 14 in sequence. The locking rod 321 is fitted with an anti-detachment component 322 at the connecting end 3211. The anti-detachment component 322 is disposed in the receiving groove 14 and can prevent the locking rod 321 from coming out of the second through hole 13 when it is not in use. Specifically, the anti-detachment component 322 is a locking nut, which is threadedly connected to the connecting end 3211. In other specific embodiments, the end of the locking rod 321 away from the movable pad 2 has a second threaded hole. The operator can use a wrench to turn the locking rod 321 at the second threaded hole so that the locking rod 321 passes into the connecting hole 21 and is threadedly connected to the movable pad 2. After the locking rod 321 is connected to the movable pad 2, the movable pad 2 can be moved away from the bearing seat 8 by pulling the locking rod 321.

[0045] When disassembling the bearing housing 8, the clamping rod is in the position of pressing the movable pad 2 against the bearing housing 8. First, the operator turns the clamping rod, which screws into the first through hole 12, releasing the movable pad 2. At this time, the movable pad 2 can still remain in contact with the bearing housing 8. The operator then turns the locking rod 321, and the connecting end 3211 of the locking rod 321 extends into the connecting hole 21. Continuing to turn the locking rod 321, the locking rod 321 connects with the movable pad 2 in the connecting hole 21. Pulling the locking rod 321 causes the movable pad 2 to move away from the bearing housing 8 within the gap 111. When installing the bearing housing 8, the locking rod 321 is pushed in the reverse direction. The locking rod 321 moves the movable pad 2 closer to the bearing housing 8 and makes it fit against the bearing housing 8. The clamping rod is turned, and the clamping rod is screwed out of the first through hole 12 and abuts against the movable pad 2. The movable pad 2 presses against the bearing housing 8. Then the locking rod 321 is pulled to disengage it from the movable pad 2, and the bearing housing 8 is positioned between the movable pad 2 and the archway 1. The tightening and loosening structure 3 is simple and easy to operate, which helps to save operating space and improves the problem that the movable pad 2 is difficult to disassemble due to the narrow operating space, thus affecting the disassembly operation of the roller system 81.

[0046] Example 3:

[0047] The difference between this embodiment and Embodiment 2 is that in this embodiment, a telescopic sleeve is fitted onto the end of the clamping rod near the movable pad 2. When the clamping rod presses against the movable pad 2, the telescopic sleeve abuts against the movable pad 2. A spring is provided between the telescopic sleeve and the clamping rod. The extension and retraction direction of the spring is consistent with the length direction of the clamping rod. When the clamping rod abuts against the movable pad 2 through the telescopic sleeve, the spring is compressed. The spring force acts on the movable pad 2 through the telescopic sleeve, which helps to improve the clamping force between the movable pad 2 and the bearing seat 8, thereby improving the stability of the bearing seat 8's positioning.

[0048] In some other specific embodiments, the outer wall of the abutment rod is provided with a groove, the length direction of the groove is consistent with the extension direction of the spring, and the telescopic sleeve is provided with a protrusion. The protrusion is slidably connected to the abutment rod in the groove. The protrusion slides in the groove and can guide the movement of the telescopic sleeve.

[0049] Example 4:

[0050] The difference between this embodiment and the previous embodiment is that this embodiment makes further structural optimizations to the archway 1. Please refer to [link / reference]. Figure 5 and Figure 6 .

[0051] Please see Figure 5 In this embodiment, a fixed pad 4 is provided on the inner wall of the archway 1. The fixed pad 4 is correspondingly provided with the movable pad 2. When the bearing seat 8 is installed, it is placed between the movable pad 2 and the fixed pad 4. The movable pad 2 and the fixed pad 4 cooperate to clamp the bearing seat 8.

[0052] In a preferred embodiment, an adjusting component 5 for raising and lowering the bearing seat 8 is provided between the bearing seat 8 and the archway 1. Two bearing seats 8 may be provided, spaced apart along the Y-axis. During electrode rolling, the electrode passes through the gap between the two bearing seats 8, and the roller system 81 on the two bearing seats 8 can perform rolling processing on the electrode. By setting the adjusting component 5, the gap between the two bearing seats 8 can be adjusted to meet different electrode rolling requirements.

[0053] As shown in some specific embodiments, the two bearing seats 8 spaced apart along the Y-axis include an upper bearing seat 8 and a lower bearing seat 8. The adjustment assembly 5 includes an adjustment screw 51, which passes through the archway 1 into the upper bearing seat 8 and is threadedly connected to the upper bearing seat 8. By turning the adjustment screw 51, the upper bearing seat 8 can be adjusted up and down along the Y-axis.

[0054] Furthermore, the lower bearing housing 8 can be driven by a drive unit for driving the lower bearing housing 8 to move up and down along the Y-axis. Specifically, the drive unit preferably, but not limited to, is a hydraulic station. The drive unit drives the lower bearing housing 8 to move along the Y-axis. The adjustment component 5 can adjust the positions of the upper bearing housing 8 and the lower bearing housing 8 respectively to adjust the gap between the upper bearing housing 8 and the lower bearing housing 8, which is convenient to operate.

[0055] Please see Figure 6 In a preferred embodiment, a limiting plate 7 is provided on the archway 1. Specifically, the limiting plate 7 is arranged parallel to the archway 1, and the bearing seat 8 is located at one end of the limiting plate 7 in the X direction. The limiting plate 7 restricts the movement of the bearing seat 8 in the X direction. In some specific embodiments shown, the limiting plate 7 has a waist-shaped hole, and the limiting plate 7 can be bolted to the archway 1 at the waist-shaped hole. The installation position of the limiting plate 7 on the archway 1 can be adjusted at the waist-shaped hole.

The electrode unwinding mechanism and the electrode winding mechanism are known to those skilled in the art and are achievable, and will not be described in detail in this embodiment.

[0059] The movable pad 2 can be adjusted by the locking structure, which can save the space required for the disassembly and assembly of the roller system 81, which is conducive to the compact and reasonable spatial layout of the roller system 81, thereby saving the space occupied by the roller pressing equipment and making the disassembly and assembly of the roller system 81 convenient.
