The pole piece base coating gravure machine has the main function that graphene is coated on the surfaces of copper and aluminum foil base materials, some metal powder possibly falls on pole pieces in the production and processing engineering of positive and negative pole piece materials (copper and aluminum foils), and if the powder is not timely treated, the powder is probably dissolved in the positive and negative pole materials after being coated.

If metal powder is blended into positive and negative electrode materials, the battery cannot be charged and discharged, or migration of lithium ions can be hindered, and further performance of the battery is reduced, so that dust removal treatment is required to be carried out on a pole piece before coating, but in the prior art, a manual operation mode is generally adopted to carry out dust removal treatment on a base material before coating, the manual dust removal mode not only makes coating procedures of the pole piece become complicated, the working efficiency is low, the production efficiency is low, the labor intensity of workers is high, and the labor cost of enterprises is high, in addition, the equipment must be stopped to operate in a manual dust removal process, so that the working speed of the equipment is reduced, and the equipment does not meet requirements of large-scale batch production of the enterprises.
