The utility model belongs to the field of lithium batteries, and particularly relates to a dust removal mechanism and current collector roll welding equipment. The dust removal mechanism comprises a first dust removal device; the first dust removal device comprises two first dust removal units which are symmetrically arranged; each first dust removal unit comprises a negative pressure cavity, a first driving roller arranged in the negative pressure cavity and a rolling brush arranged on the first driving roller; and the negative pressure cavity is provided with a dust suction port and an air suction port which are communicated with each other. According to the dust removal mechanism and the current collector roll welding equipment, through the design of the dust suction opening and the air suction opening in the outer wall of the negative pressure cavity, negative pressure gas can be used in a concentrated mode, the physical wind resistance of the gas is reduced, the utilization rate of the negative pressure
