Description

Technical Field

[0001] The utility model relates to the technical field of ribbon printing processing, in particular to an automatic ribbon feeding device for a printing line. Background Art

[0002] The printing production line is used for printing and drying of ribbons after printing. It mainly includes printing equipment and drying equipment. However, how to make the ribbon automatically enter the printing equipment has become an urgent problem to be solved;

[0003] Existing automatic tape feeding equipment is usually as shown in a printing device (authorization announcement number CN217867292U) and a tape printing machine (authorization announcement number CN203901933U) disclosed in a Chinese patent that can assist in the winding of elastic tape processing. One is to drive the winding roller to rotate by a driving motor in the winding device, and the other is to drive the winding shaft to rotate by a second stepper motor in the winding assembly. The principles are the same; however, they have a common disadvantage: when the winding roller is driven by the motor to rotate, the tension of the tape cannot be adjusted, and the tape can only be wound in a single manner. When the tape is wound, if the tension is too small, the tape roll will become loose, affecting subsequent processing and use; and if the tension is too large, the tape roll will be too tight, resulting in greater internal stress, causing the tape roll to deform, break, and other problems during subsequent processing and use.
