Utility model content
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of lithium battery pole piece coating device.This lithium battery pole piece coating apparatus structure is simple, rationally, the coating uniform of its substrate sheets is consistent, dries homogeneous heating, can improve drying effect, to such an extent as to effectively improve product quality.
The technical solution of the utility model comprises unreeling carries out device, drying channel and corresponding drying unit with wrap-up, painting, described painting is carried out device and is comprised slurry tank, be located at the applicator roll in described slurry tank, and the defeated roller of corresponding input, described drying unit comprises gas heater, be connected to a pair or some of relative both sides of described drying channel symmetrically to cloth tuyere, and be located at the exhaust nozzle of corresponding site of described drying channel.
Described exhaust nozzle is located at the upper and lower of the output of corresponding described drying channel and/or relative both sides, left and right in pairs.
1, lithium battery pole piece coating device according to claim 1, is characterized in that described exhaust nozzle is located at the relative both sides in left and right or front and back of corresponding one end of corresponding described drying channel.
Described cloth tuyere is connected with corresponding gas heater respectively by trousers shape pipe with exhaust nozzle.
The utility model lithium battery pole piece coating device can improve the slurry coating quality of electrodes of lithium-ion batteries and the uniformity of coating, make the hot property of pole piece and electric performance stablity, reliable, and then improve the quality of lithium battery product, the performance etc. such as capacity, safety of lithium ion battery can be improved to a certain extent.
Accompanying drawing explanation
Fig. 1 is the utility model one example structure schematic diagram.Fig. 2 is another embodiment warm-up mill structural representation of the utility model.
Detailed description of the invention
