Description

Technical Field

[0001] The invention relates to the technical field of lithium battery processing, in particular to an internally positioned anti-loosening rotary cutting mechanism for a lithium battery slice making machine. Background Art

[0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The positive electrode of a lithium battery can be roughly divided into materials such as lithium cobalt oxide, lithium manganese oxide, and lithium iron phosphate. During charge and discharge, the lithium ions in the positive electrode will undergo deintercalation and intercalation reactions. The negative electrode of a lithium battery can be roughly divided into materials such as tin-based and alloy negative electrode materials and carbon negative electrode materials, usually graphite, which has a high specific capacity and reversibility during charge and discharge. The isolation membrane is used to isolate the positive and negative electrodes to prevent short circuits while allowing lithium ions to pass through. The electrolyte conducts lithium ions in the battery, allowing lithium ions to move between the positive and negative electrodes to complete the charge and discharge process. The production and processing of lithium batteries is a relatively complex process, which mainly includes electrode production, cell assembly, battery testing and packaging.

[0003] Lithium-ion battery production is a key link in the lithium battery production process. Accurately weigh the right amount of positive or negative electrode active materials, conductive agents, binders and solvents, add the raw materials into the stirring equipment in a certain order, first stir at a low speed to make the components initially mixed, then gradually increase the stirring speed to make the slurry reach a uniformly dispersed state, place the coated and rolled pole pieces at the feed port of the slitting machine for easy slitting.

[0004] Existing slitting machines, such as the rotary cutting mechanism used in a lithium battery making machine disclosed in publication number "CN218611923U", "the blade assembly can be initially fixed on the knife roller by plugging, and the blade assembly is more convenient to install. At the same time, by rotating the screw, multiple elastic plugs can be driven to fix multiple blade assemblies at the same time, making the disassembly and assembly of the blade assembly very convenient." However, in actual use, when the knife roller rotates at high speed, especially at the moment of starting, speed change or impact load, the knife roller will generate a large inertial force and torque to impact the screw. Although the screw itself has a certain anti-rotation performance through the thread, under long-term and frequent impact, the screw becomes loose, resulting in a weakened anti-rotation effect, and finally causing the screw to rotate, making the blade assembly fixation failure. On the high-speed rotating knife roller, once the blade loosens and is thrown out, it will pose a serious safety threat to the equipment and operators. Summary of the invention
