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...

However, the main obstacle in the development process is the high price due to the complicated production process, too much energy consumption and the large equipment footprint

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 house 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 the on-site operators, which also restricts the development of the width of the pole piece coated by the pole piece coating machine in a wider direction.

[0003] In the prior art, the battery pole piece double-sided coating machine is set in a horizontal and straight line. In order to save the land area, the total length of the heating device is usually designed to be short, generally 18 meters. It is installed on the same side of the coating machine. In order to enable the coating machine to run normally and prevent conflicts between the unwinding and rewinding tapes, the rewinding tape of the winding machine has to be set either across the top of the uncoiler or under the uncoiler. setting, thus lengthening the length of the tape, affecting the positioning accuracy of the coating, and the space around the uncoiler and winder is narrow, the forklift cannot be driven in, and the crane cannot reach it, so that large raw materials cannot be transported, so they can only be disassembled into one Small items under 100 kg are manually loaded and unloaded, which also restricts the maximum diameter of the battery pole piece reel
