Abstract

The invention discloses a drying and slitting all-in-one machine for lithium battery pole pieces. The drying and slitting all-in-one machine comprises an unreeling module, a drying module, a cooling module and a slitting reeling module, wherein a pole piece baseband is arranged on an unreeling air-expanding assembly of the unreeling module, enters the drying module to dry, and enters the slitting reeling module after being cooled by a cooling roller of the cooling module; the slitting reeling module comprises a slitting knife group and two reeling rollers; the pole piece baseband is slit by the slitting knife group to form two pile piece bands; and each of the two pile piece bands is separately equipped with a reeling roller for reeling. According to the drying and slitting all-in-one machine disclosed by the invention, the slitting reeling module is arranged behind the cooling module, and the cooled pole piece baseband is directly slit, the cooled pole piece baseband does not need to reel, and is unreeled onto the slitting reeling module again, so that a production process of the lithium battery pole piece baseband is optimized, production cost is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery production and processing equipment, in particular to an integrated drying, slitting and cutting machine for lithium battery pole pieces. Background technique [0002] At present, the lithium battery industry at home and abroad has a good development prospect. Lithium-ion batteries have been widely used in portable electrical appliances such as laptop computers, cameras, and mobile communications due to their unique performance advantages. The currently developed high-capacity lithium-ion battery has been tested in electric vehicles and is expected to become one of the main power sources for electric vehicles in the 21st century, and will be used in satellites, aerospace and energy storage. With the shortage of energy and the pressure of the world's environmental protection. Lithium batteries are now widely used in the electric vehicle industry, especially the emergence of lithium iron ph...
