Description

Technical Field

[0001] The utility model relates to the technical field of battery component processing devices, in particular to a pole piece cutting device. Background Art

[0002] A battery refers to a cup, trough or other container or part of the space of a composite container that contains an electrolyte solution and metal electrodes to generate electric current. It is a device that can convert chemical energy into electrical energy. The battery is composed of zinc skin, carbon rods, mercury, sulfate, copper caps and pole pieces. Simply put, the pole piece is the core of the battery. During the processing of the pole piece, a controlled slitting device is required to cut the battery pole piece roll.

[0003] The publication number in the existing public technology is: CN219193926U. A battery pole piece roll slitting device, the utility model includes a bottom component, a connecting component and a feeding component, the feeding component is connected to the middle of the upper part of the bottom component, the unwinding component is connected to one side of the upper part of the bottom component, the slitting component is connected to the other side of the upper part of the bottom component, and the upper side of the slitting component is connected to the connecting component. The utility model flattens and pushes the battery pole piece by setting the feeding component, so that the components in the slitting device are compactly distributed, the volume of the slitting device is reduced, and the space occupied by the slitting device is reduced. By setting the connecting component, the rigid contact between the cutter and the bottom plate is avoided, the impact force between the cutter and the bottom plate is reduced, which is conducive to improving the service life of the cutter.

[0004] However, the above patent still has certain disadvantages when in use: it lacks a fixing structure for the pole piece when cutting the pole piece, which easily causes the pole pieces on both sides of the cutter to deform and warp when squeezed and cut, which not only affects the cutting effect but also affects the subsequent use quality. In addition, using a set of cutters for operation for a long time will not only cause the cutters to wear more seriously and shorten their service life, but also the burrs on the surface of the cutters due to wear will affect the cutting quality of the pole piece, reducing the use effect of the device. Moreover, the grinding of the cutter needs to be manually handled by personnel, which increases the labor intensity of personnel and is time-consuming and labor-intensive.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0039] Working principle: In actual use, the movable plate 4 can be moved by rotating the first adjusting screw 2, thereby facilitating the installation operation of the pole piece roller 7. Then, the pole piece to be cut can be placed in the lower position of the driving roller 12, and the second adjusting screw 14 can be rotated so that the friction ring 11 on the surface of the driving roller 12 can just abut against the surface position of the pole piece.

At this time, the operation of the third motor 26 can drive the adjustment block 18 to rotate, so that the cutter 19 on its surface can be replaced, and then the unused cutter 19 is facing downward for subsequent use. The recycling of multiple sets of cutters 19 can effectively avoid the shortening of the life caused by excessive use of a single set of blades, and the used cutter 19 can be polished by the grindstone 23 that moves back and forth after rotation to avoid the generation of burrs, thereby improving the cutting effect, reducing the consumption of subsequent manual polishing, and improving the use effect of the device.
