▎ 摘　　要

NOVELTY - The production line has an operating platform (1) whose side is connected with a feeding unit (2) and a knockout unit (3). The feeding unit is connected with the knockout unit by a conveying belt transmission mechanism. A side of the knockout unit is connected with a side of a printing unit (4) by the conveying belt transmission mechanism. Another side of the printing unit is connected with a drying unit (5) by the conveying belt transmission mechanism. A mold cutting and head welding unit is connected with two long sides of a welding unit (11) by the conveying belt transmission mechanism. Two long sides of the welding unit are connected with a tail sealing unit (12) by the conveying belt transmission mechanism. The tail sealing unit is connected with a pulling unit (13) by the conveying belt transmission mechanism. USE - Automatic graphene ground heating printed envelope production line. ADVANTAGE - The production line has high automation degree and high production efficiency, and realizes combined envelope printing process by utilizing resources in a rational manner, and reduces energy consumption. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an automatic graphene ground heating printed envelope production line.
