Description

Technical Field

[0001] This utility model relates to the field of lithium battery cutting technology, specifically a lithium battery cutting tension adjustment device. Background Technology

[0002] Lithium-ion battery slitting is an important process in lithium-ion battery production. Specifically, it refers to the process of cutting a whole roll of wide material into multiple rolls of narrower specifications using a high-speed rotating circular blade or other cutting equipment.

[0003] In traditional slitting tables, the distance between the unwinding and take-up rollers during operation means that the roll material is not effectively supported by them, which can cause the translation path to tilt. This can also affect the cutting position during slitting, requiring the cutter head to be displaced in coordination to maintain slitting stability; otherwise, the slitting quality will be affected. Utility Model Content

[0004] The purpose of this invention is to provide a lithium battery slitting tension adjustment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lithium battery slitting tension adjustment device includes a worktable, on which a winding and unwinding section and a plurality of tension rollers for adjusting the tension of the roll material are arranged in parallel. The tension rollers are adjustablely connected to the worktable via an adjustment assembly, and the tension rollers are movably connected in a direction closer to or further away from the worktable.

[0007] By setting multiple tension rollers, better support is provided for the slitting of the roll material, avoiding inaccurate slitting caused by the deformation of the roll material during the slitting process.

[0008] As a further embodiment of this utility model: the unwinding and winding section includes an unwinding assembly and a winding assembly, and the tension roller is located between the unwinding assembly and the winding assembly.

[0009] By setting a tension roller between the unwinding assembly and the winding assembly, the roll material to be cut between the unwinding assembly and the winding assembly can be supported.

[0010] As a further embodiment of this utility model: the unwinding assembly includes an unwinding roller, the worktable is provided with an unwinding motor, and the unwinding motor is poweredly connected to the unwinding roller through an unwinding reduction gearbox.

[0011] The unwinding roller is driven to rotate by the unwinding motor and the unwinding gearbox in order to unwind the roll.

[0012] As a further embodiment of this utility model: the winding assembly includes a winding roller, and a winding motor is provided on the worktable. The winding motor is poweredly connected to the winding roller through a winding gearbox.

[0013] The winding roller is driven to rotate by a winding motor and a winding gearbox in order to perform winding.

[0014] As a further embodiment of this utility model: the workbench is provided with two opening and closing roller frames for supporting the unwinding roller and the winding roller respectively. The opening and closing roller frames are provided with hinge shafts. The hinge shafts are rotatably connected to the workbench through a hinge seat on the workbench. The hinge seat is provided with a pin for limiting the position.

[0015] When it is necessary to disassemble or assemble lithium battery rolls, the pin can be pulled out to allow the opening and closing roller frame to rotate around the hinge axis, thereby opening or closing the ends of the unwinding and take-up rollers. This makes it easy to install lithium battery rolls onto the unwinding roller or remove them from the take-up roller. The opening and closing roller frame simplifies the disassembly and assembly process of lithium battery rolls and improves work efficiency.

[0016] As a further embodiment of this utility model, the tensioning rollers are provided with an even number.

[0017] In other words, each slitting blade is equipped with two tension rollers that work together. The arrangement and symmetrical layout of the tension rollers ensure that the lithium battery roll is subjected to uniform tension during the slitting process, avoiding problems such as roll displacement or breakage caused by uneven tension.

[0018] As a further embodiment of this utility model: the adjustment assembly includes a support plate fixedly connected to the worktable, and both ends of the tension roller are slidably connected to the worktable via the support plate.

[0019] The tensioning roller can move up and down through the support plate, thereby tensioning the roll material and ensuring that the roll material maintains a stable tension and translation path during transmission.

[0020] As a further embodiment of this utility model: the support plate is provided with a vertically arranged lifting slot, the support plate is provided with a connecting seat, the upper end of the connecting seat is rotatably connected with an adjusting bolt, the adjusting bolt is threadedly connected with a lifting block, the end of the lifting block near the tension roller is provided with a connecting bushing, the connecting bushing passes through the lifting slot and is connected to the rotating shaft of the tension roller.

[0021] By setting an adjusting bolt, the lifting block is driven to move up and down, and in turn, the tension roller is driven to move up and down by the up-and-down moving lifting block.

[0022] As a further embodiment of this utility model: the support plate is connected to the workbench by connecting bolts, the support plate is provided with adjustment holes, and the connecting bolts pass through the adjustment holes and are threadedly connected to the workbench.

[0023] By setting adjustment holes, when it is necessary to disassemble and replace the tension roller, the connecting bolts can be loosened, and then the support plate can be moved towards the tension roller to remove the tension roller, which reduces the difficulty of disassembling and replacing the tension roller.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. This application sets multiple tension rollers on the worktable to support the roll material, and sets two tension rollers at each slitting head to support the roll material, thereby ensuring that the roll material will not tilt during slitting, improving the stability and quality of slitting.

[0026] 2. This application provides an adjustment component to facilitate the adjustment of the tension roller for better support of the roll material. The adjustment holes also facilitate the disassembly and installation of the tension roller, reducing the difficulty of maintenance.

[0027] 3. In this application, one end of the take-up and unwind rolls is connected to the worktable via an opening and closing roll frame. During operation, the roller shaft of the take-up and unwind rolls is connected to the opening and closing roll frame, which provides support. When it is necessary to load or unload the roll, the opening and closing roll frame can be rotated to quickly load or unload the roll, thus improving work efficiency. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1 In this embodiment of the utility model, a lithium battery slitting tension adjustment device includes a workbench 1 and a take-up and unwinding section disposed on the workbench 1. The take-up and unwinding section includes an unwinding component 2 and a take-up component 3 disposed at both ends of the workbench 1, and a tensioning roller 4 in the middle of the workbench 1 for pressing against the lithium battery roll.

[0034] At least two tension rollers 4 are arranged side by side along the length of the worktable 1. Each end of the tension roller 4 is provided with an adjustment component 5 for adjusting its height. In this embodiment, the tension rollers 4 are set in even numbers and are symmetrically arranged on both sides of the slitting head. The setting of even numbers of tension rollers 4 and the symmetrical layout can ensure that the lithium battery roll is subjected to uniform tension during the slitting process, avoiding problems such as roll displacement or breakage caused by uneven tension.

[0035] like Figure 3 As shown, the adjustment assembly 5 includes a support plate 51, a lifting slot 511 formed in the middle of the vertical plate of the support plate 51 for the tension roller 4 to be inserted and moved longitudinally, an adjustment hole 512 symmetrically formed on the horizontal plate of the support plate 51, a connecting bolt 52 passing through the adjustment hole 512 and screwed to the worktable 1 for locking the support plate 51 on the worktable 1, a lifting block 53 fitted on the end of the tension roller 4 shaft through a connecting bushing 531, a connecting seat 513 fixedly connected in the middle of the horizontal plate of the support plate 51, and an adjustment bolt 54 rotatably connected to the connecting seat 513 and screwed to the lifting block 53 for driving the lifting block 53 to rise and fall. The connecting bushing 531 is fixedly connected to the lifting block 53.

[0036] In use, the roll material is first placed on the unwinding assembly 2 and then transferred through the tension roller 4 and the take-up assembly 3. The height of the tension roller 4 is adjusted by rotating the adjusting bolt 54 to adjust the required tension. Since at least two tension rollers 4 are arranged side-by-side along the length of the worktable 1, and the height of each tension roller 4 is adjustable at both ends via the adjusting assembly 5, a stable tension and translational path for the roll material can be ensured during transfer. Specifically, the adjusting bolt 54 is turned to rotate it on the connecting seat 513. Due to the interaction between the adjusting bolt 54 and the lifting block... The tension roller 4 is connected by bolt 53, so rotating the adjusting bolt 54 will cause the lifting block 53 to rise and fall. The lifting block 53 is connected to the end of the rotating shaft of the tension roller 4 through the connecting bushing 531, which will together drive the tension roller 4 to rise and fall. The end of the rotating shaft of the tension roller 4 moves in the lifting slot 511 to maintain its verticality. When the tension roller 4 needs to be replaced, the connecting bolt 52 is unscrewed from the workbench 1 to unlock the support plate 51, which is then pulled towards both ends of the tension roller 4. This allows the support plate 51 to take the lifting block 53 away from the end of the rotating shaft of the tension roller 4, so that the tension roller 4 can be replaced.

[0037] like Figure 1 As shown, the unwinding assembly 2 includes an unwinding roller 21 rotatably mounted on one end of the workbench 1, an unwinding gearbox 22 fixedly mounted on the side of the workbench 1 with its output shaft connected to the unwinding roller 21, and an unwinding motor 23 fixedly mounted on the unwinding gearbox 22 with its output shaft connected to the input shaft of the unwinding gearbox 22. After the unwinding motor 23 is started, it drives the unwinding gearbox 22 through its output shaft, thereby driving the unwinding roller 21 to rotate. The lithium battery roll on the unwinding roller 21 gradually unfolds as it rotates, for use in subsequent slitting processes.

[0038] The winding assembly 3 includes a winding roller 31 rotatably mounted on the end of the worktable 1 away from the unwinding assembly 2, a winding gearbox 32 fixedly mounted on the side of the worktable 1 with its output shaft connected to the winding roller 31, and a winding motor 33 fixedly mounted on the winding gearbox 32 with its output shaft connected to the input shaft of the winding gearbox 32. After the winding motor 33 is started, it drives the winding gearbox 32 through its output shaft, which in turn drives the winding roller 31 to rotate. As the winding roller 31 rotates, the lithium battery roll is gradually wound up, completing the collection work after the slitting process.

[0039] like Figure 2As shown, both the end of the unwinding roller 21 away from the unwinding deceleration box 22 and the end of the take-up roller 31 away from the take-up deceleration box 32 are provided with an opening and closing roller frame 6 that is hinged to the worktable 1 for loading and unloading the roll material from the unwinding roller 21 and the take-up roller 31. The worktable 1 has a hinge seat 11 at the position corresponding to the opening and closing roller frame 6. The opening and closing roller frame 6 is rotatably connected to the hinge seat 11 through a hinge shaft 61. A rectangular groove is opened in the center of both the hinge shaft 61 and the hinge seat 11. A pin 7 is inserted into the rectangular groove to lock the opening and closing roller frame 6 at the end position of the unwinding roller 21 and the take-up roller 31. In this embodiment, the pin 7 is a rectangular pin. The pin 7 is inserted into the hinge seat 11 and the hinge shaft 61. When the pin 7 is inserted, the hinge shaft 61 and the hinge seat 11 cannot rotate relative to each other. When the pin 7 is pulled out, the hinge shaft 61 and the hinge seat 11 can rotate freely.

[0040] When it is necessary to disassemble or assemble lithium battery rolls, the pin 7 can be pulled out to allow the opening and closing roller frame 6 to rotate around the hinge shaft 61, thereby opening or closing the ends of the unwinding roller 21 and the take-up roller 31. In this way, the lithium battery rolls can be easily installed onto the unwinding roller 21 or removed from the take-up roller 31. The setting of the opening and closing roller frame 6 simplifies the disassembly and assembly process of lithium battery rolls and improves work efficiency.
