Description

Technical Field

[0001] The invention relates to the technical field of packaging, and in particular to a mask packaging machine. Background Art

[0002] Masks are sanitary products that have a certain filtering effect on the air entering the lungs. After fighting the epidemic, people's awareness of wearing masks has increased, and masks have become daily necessities. Masks need to be packaged after they are produced and processed. With the increase in demand for masks, the traditional manual packaging method can no longer meet production needs and manual packaging will pollute the masks; most of the mask packaging machines in the prior art are semi-automatic and have low production efficiency.
