[0032] The paper is drawn from the upper and lower surfaces of the two sets of dust-blowing cylinders 4 and the surface of the adjusting roller 6 to the input end of the printing press. The paper is fed from top to bottom and is positioned between the two sets of limiting plates 12. Then, the servo motor 17 is turned on, which drives the bidirectional lead screw 9 to rotate. With the bidirectional lead screw 9 threadedly connected to the threaded sleeve 8, the bidirectional lead screw 9 drives the two sets of threaded sleeves 8 to move towards each other and approach each other. The threaded sleeves 8, through the placement plate 10, drive the limiting plates 12 to approach each other and bring the two sets of limiting plates 12 into contact with the outer wall of the paper. Under the elastic cooperation of the spring 11, the limiting plates 12 are brought closer together. The paper is elastically contacted, and two sets of limiting plates 12 center and limit the paper to prevent it from deviating, thereby improving the accuracy of paper input. When the tension of the paper needs to be adjusted, the hydraulic cylinder 13 is opened, which drives the push arm 14 to move. The push arm 14 drives the adjusting frame 7 to rotate around the hinge shaft 16 via the linkage shaft 15. The adjusting frame 7 drives the adjusting roller 6 to rotate, and the adjusting roller 6 provides force to the paper from the bottom, thereby tensioning the paper. This achieves convenient centering, clamping, and limiting of the paper's movement direction, and facilitates the linkage adjustment of the paper's tension.

Air is ejected from the holes on the surface of the dust blower 4 to blow away debris from the upper and lower surfaces of the paper, thereby ensuring the cleanliness of the paper and improving printing quality. This achieves convenient rolling and blowing of debris from the paper surface, thus improving the quality of paper printing.
[0038] Working principle: Paper is drawn from the upper and lower surfaces of the two sets of dust blowing cylinders 4 and the surface of the adjusting roller 6 to the input end of the printing press. The paper is fed from top to bottom and is positioned between the two sets of limiting plates 12. The servo motor 17 drives the bidirectional lead screw 9 to rotate, which in turn drives the two sets of threaded sleeves 8 to move towards each other and closer together. The threaded sleeves 8, through the placement plate 10, drive the limiting plates 12 to move closer together and contact the outer wall of the paper. Under the elastic cooperation of the spring 11, the limiting plates 12 elastically contact the paper, thereby centering and limiting the paper by the two sets of limiting plates 12 to prevent paper deviation and improve the accuracy of paper input. When it is necessary to adjust the paper tension... During operation, the hydraulic cylinder 13 drives the push arm 14 to move, and the push arm 14 drives the adjusting frame 7 to rotate around the hinge shaft 16 via the linkage shaft 15. The adjusting frame 7 drives the adjusting roller 6 to rotate, and the adjusting roller 6 provides force to the paper from the bottom, thereby tensioning the paper. During the paper conveying process, the dust blowing cylinder 4 is connected to an external air pump through a flexible hose. The external air pump pumps air into the dust blowing cylinder 4, and the adapter sleeve 2 provides movable support for the dust blowing cylinder 4. Air is sprayed out from the holes on the surface of the dust blowing cylinder 4 to blow away debris from the upper and lower surfaces of the paper, thereby ensuring the cleanliness of the paper and improving the printing quality. The above is the complete usage of the tension adjustment device of the paper card printing machine.
