Cutter space one-time adjustable splitting cutter holder used for production and processing of lithium battery cover plate

Abstract

The invention discloses a cutter space one-time adjustable splitting cutter holder used for production and processing of a lithium battery cover plate. The cutter space one-time adjustable splitting cutter holder structurally comprises upper splitting cutters, an upper cutter space adjusting device, a guide roller, a lower cutter space adjusting device, lower splitting cutters and a cutter holderbody, wherein the cutter holder body is provided with the lower cutter space adjusting device and the upper cutter space adjusting device in the sequence from down to up. Compared with the prior art,the cutter space one-time adjustable splitting cutter holder has the beneficial effects that, through the combination arrangement of connecting plates, ear clips, spring groups and rotary lifting groups, the space between each splitting two cutter is thus adjustable; based on the elasticity of the springs, spring rings of the springs can be enlarged or lessened in an equidistant mode, so that thespaces of a plurality of splitting cutters can be adjusted at one time, the adjusting frequency is high, and adjusting one by one is not needed, the speed of the space adjusting is fast, the requirements of the lithium battery cover plate at different splitting scales can be met, the application range is wide, the cost invested to the cover plate splitting is low, and the cutter space one-time adjustable splitting cutter holder is valuable to be popularized and used.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a slitting knife holder for production and processing of lithium battery cover plates whose spacing between cutters can be adjusted once. Background technique [0002] When the lithium battery is in use, it needs to be sealed through the cover plate. Since there are various sizes and specifications of the lithium battery, different sizes and specifications of the lithium battery cover plate are required, and the lithium battery cover plate needs to be cut during production. [0003] Most of the slitting blades on the market are fixed for the production and processing of lithium battery cover plates, and the distance between the slitting blades is fixed and cannot be adjusted. The cover plate needs cutter holders with different spacing, so the cost of cutting the cover plate is relatively high. There are also a small number of slitting knives and the spacing between the ...

Problems solved by technology

[0003] Most of the slitting blades on the market are fixed for the production and processing of lithium battery cover plates, and the distance between the slitting blades is fixed and cannot be adjusted. The cover plate needs cutter holders with different spacing, so the cost of cutting the cover plate is relatively high. There are also a small number of slitting knives and the spacing between the slitting knives can be adjusted, but the slitting knives need to be adjusted one by one to adjust the efficiency. Low, low pitch adjustment accuracy, will greatly affect the cutting of the cover plate specification
