Description

technical field

[0001] The invention relates to the field of coating machines, in particular to a parallel double-sided coating machine. Background technique

[0002] In the front-end equipment industry of lithium batteries, the existing extrusion coating machines are mainly single-sided coating machines, and the coating process structure consists of: unwinding-head (coating)-drying-drawing-winding. The coating process requires coating on both sides of the substrate. After one side is coated, the second side is reversed to complete the overall coating. In this way, the unwinding of the base material will be repeated once, and a coating process will be added. The equipment utilization rate will be low, the output will be low, and the power consumption will be high. This leads to a substantial increase in the physical properties of the battery pole piece (unstable tension, wrinkling and winding uniformity), chemical properties (slurry content density, electrode ions, etc.) an...
