Material pressing mechanism, automatic printing machine and material pressing method for automatic printing machine

The present disclosure provides a material pressing mechanism applied for pressing a to-be-printed article. The material pressing mechanism includes a first set, a second set and at least one first lace. The second set is spaced apart from the first set. One end of the at least one first lace is connected to the first set and the other end of the at least one lace is connected to the second set. As the to-be-printed article is dynamically transmitted to a lower side of the at least one first lace, the to-be-printed article is restricted by the at least one lace. Therefore, the bow of the to-be-printed article can be avoided.
