Efficient energy-saving combined type battery pole piece two-side coater

Abstract

The invention discloses an efficient energy-saving combined type battery pole piece two-side coater, which fully utilizes space, saves land utilization cost, improves production efficiency and improves on-site management levels. The efficient energy-saving combined type battery pole piece two-side coater comprises a coating device formed by a forward coating head and a reverse coating head, an uncoiling machine, a coiling machine and a heat drying device, wherein two sets of individually-operated two-side coaters are divided into an upper coater and a lower coater which are arranged in an up-and-down superposition mode; the uncoiling machine, the coiling machine and the coating device are arranged at the two ends of the upper and lower coaters respectively; and the heat drying device consists of at least two flow equalization ovens with circulation flow equalization hot air devices. According to the coater, the floor space of the coater is greatly reduced, and the cost is saved; operating environments at the periphery of the coater are improved, and the management level of an operation site is improved; by the flow equalization ovens, the coating width of a battery pole piece can be adjusted to be 800mm, but the edge of the battery pole piece cannot be curled; and therefore, the drying device is lengthened, the operating speed of the coater is increased, and the production efficiency can be greatly improved.

Description

technical field

[0001] The invention relates to a battery pole piece coating machine, in particular to a battery pole piece double-sided coating machine with high production efficiency, large-scale production and small footprint. Background technique

[0002] Lithium-powered batteries, as green energy, are being vigorously promoted across the country. However, the main obstacle in the development process is the high price, because the production process is complicated, the energy consumption is too much, and the equipment occupies a large area. In particular, the pole piece coating machine has huge equipment, occupies a large area of ​​the factory building, and the cost of land use is very high (especially when land prices and housing prices soar), and when the equipment is running, it consumes a lot of power; Due to the limitation of conditions, the layout of each unit equipment of the pole piece coating machine is very compact, which greatly affects the working space of t...
