Description

Technical Field

[0001] The utility model belongs to the technical field of battery foil slitting, and in particular relates to an unwinding mechanism for battery foil slitting. Background Art

[0002] Battery foil is one of the more important raw materials in the battery manufacturing process. In order to meet the production and assembly of batteries of different types and specifications, the battery foil coils with larger widths need to be cut into battery foil coils with smaller widths by slitting equipment according to the needs. Before slitting, the unwinding mechanism needs to smoothly feed the rolled coils into the slitting equipment at a certain speed for transportation.

[0003] A Chinese patent document with authorization announcement number CN219341066U discloses a metal foil unwinding device, which drives an unwinding roller arranged in a fixed seat to rotate through a motor, so that the unwinding roller can transport the coil at a certain speed through its own rotation, and tighten the moving coil through an adjusting roller that can slide left and right under the action of a cylinder.

[0004] However, in the prior art, when the speed of the unwinding roller remains unchanged, the traveling speed of the coil will slow down as the diameter of the coil becomes smaller. At this time, the adjustment capacity of the components with tensioning function has reached its limit, and the coil is prone to excessive tension when the traveling speed decreases. Therefore, an unwinding mechanism for battery foil slitting is proposed. Utility Model Content

[0005] The utility model aims to provide a reeling mechanism for slitting battery foil.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A battery foil slitting unwinding mechanism comprises an unwinding assembly capable of unwinding a coil to be slit and adjusting the unwinding position of the coil in the mechanism, a tensioning assembly capable of cooperating with the unwinding assembly to tension the traveling coil, and a feeding assembly capable of feeding the coil into the slitting device at a certain speed is arranged on one side of the tensioning assembly;

[0008] The unwinding assembly includes a frame on which various components can be installed, a rotating member that can drive the coil to rotate at a certain speed, and a shifting member that can adjust the position of the coil in the mechanism.

[0009] Preferably, the displacement member comprises a first support fixedly mounted on the frame, and a support arm is movably connected to the first support.

[0010] Preferably, the rotating member comprises a first roller seat fixedly mounted behind the supporting arm, a reeling roller is arranged between the supporting arm and the first roller seat, and a first motor is fixedly connected to the rear end of the reeling roller.

[0011] Preferably, the displacement member further comprises a second support fixedly mounted in the frame, and an inclined hydraulic rod is arranged between the support arm and the second support.

[0012] Preferably: an arc-shaped limiting groove is integrally formed on the frame.

[0013] Preferably, the first support is rotatably connected to the support arm.

[0014] Preferably: the first roller seat is rotatably connected to the unwinding roller.

[0015] Preferably, the support arm and the second support are both rotatably connected to the inclined hydraulic rod.

[0016] The beneficial effect of the utility model is that when the feeding component continuously feeds the coil unwound by the unwinding component into the slitting equipment, the unwinding position of the rotating part equipped with the coil to be slit in the mechanism can be conveniently adjusted through the operation of some parts of the shifting part, so that after the tensioning component that can display the tensioning degree of the coil reaches the tensioning limit, the position of the rotating part changes, so that the mechanism can still perform the unwinding work normally.

[0032] In this embodiment: the tensioning assembly 2 includes a limit frame 201 fixedly mounted on the frame 101, a vertical hydraulic rod 202 is fixedly mounted in the limit frame 201, a telescopic end of the vertical hydraulic rod 202 is fixedly connected to a frame 203, a limit rod 204 is fixedly connected in the frame 203, a spring 205 is movably connected to the outer side of the limit rod 204, a slider 206 is movably connected between the limit rods 204, a second roller seat 207 is fixedly connected to the rear of the slider 206, and a tensioning roller 208 is arranged between the slider 206 and the second roller seat 207;

[0037] Working principle: When the mechanism is installed and used for unwinding work related to battery foil slitting, the coil is sleeved on the outer side of the unwinding roller 105, and the coil is passed from under the tensioning roller 208 and between the feeding rollers 303 in turn. Then, the tensioning roller 208 can be pressed against the coil below it through the operation of the vertical hydraulic rod 202, and the spring 205 is appropriately compressed; when feeding, the first motor 106 and the second motor 305 can be operated at the same speed at the output end, so that the rotating feeding roller 303 can continuously feed the coil into the slitting equipment at a relatively stable speed, so that the rotating unwinding roller 105 can continuously drive The coil rotates to unwind smoothly; as the diameter of the coil on the unwinding roller 105 becomes smaller, the traveling speed of the coil in this mechanism will gradually slow down, so the tension of the coil can be judged by observing the compression degree of the spring 205. When the frame 203 moves up to the highest position in the limit frame 201 and the spring 205 still has a tendency to gradually increase in compression, the inclination of the support arm 103 can be adjusted by the inclined hydraulic rod 108, so that the unwinding roller 105 can be appropriately moved in the direction close to the tensioning roller 208, so that the over-tensioned coil can be relieved to a certain extent until the coil slitting is completed.
