The invention discloses a
laser marking
machine for food production packaging, relates to the technical field of
laser marking of packaging bags, comprises a conveyor and a
laser marking head, and also comprises: a bracket; a displacement mechanism, used for driving the laser marking head to move; a sealing mechanism, used for sealing the packaging bag during the marking process; a fixed-point
smoke removal mechanism, used for fixed-point cleaning of
smoke generated by multi-position marking of the packaging bag in the sealing mechanism; the laser marking
machine for food production packaging, by sealing the top space of the packaging bag, when the laser marking head performs multi-position marking on the packaging bag,
smoke generated by laser marking inside the sealing cover will not be dispersed, thus solving the problem in the prior art that smoke can only be collected after it diffuses, resulting in incomplete smoke collection, and eliminating the problem in the prior art that a thinner and lighter packaging bag is easily offset or folded on the conveyor and difficult to mark normally by arranging an exhaust structure on one side of the packaging bag.
