Tension adjusting structure for non-woven fabric bag printing process

The tension adjusting structure comprises a base, a printing machine is fixedly installed on one side of the top of the base, supporting plates are fixedly arranged at the two ends of the other side of the top of the base, and the two ends of the sides, close to the middle of the base, of the two supporting plates are slidably connected with movable plates; a tensioning roller is fixedly arranged between the two corresponding movable plates, connecting bases are fixedly arranged on the sides, close to the printing machine, of the two tensioning rollers, cleaning brushes are fixedly arranged on the sides, away from the middles of the supporting plates, of the two connecting bases, and moving mechanisms for driving the two tensioning rollers to move oppositely are arranged in the two supporting plates. Two bidirectional lead screws rotate synchronously through meshing of a chain and two chain wheels, two tensioning rollers on the two sides are driven to clamp the non-woven fabric on the two sides, the tension a
