Description

Technical Field

[0001] The utility model relates to the technical field of slitting knife holders, in particular to a movable slitting knife holder mechanism. Background Art

[0002] A slitter is a mechanical device that cuts wide paper, mica tape, or film into multiple narrow strips. It is commonly used in papermaking machinery, wire and cable mica tape, and printing and packaging machinery. Slitter machines are primarily used for slitting mica tape, paper, insulation materials, and film. When slitting film, the position of the cutter must be adjusted frequently based on the width of the cut and the distance between the cutter and the cutter roller.

This method not only brings great difficulty to the staff, but also has the problem of inaccurate adjustment of the cutting knife position. Therefore, those skilled in the art provide a movable slitting knife holder mechanism to solve the problems raised in the above background technology. Utility Model Content
