Description

Technical Field

[0001] The utility model relates to the technical field of knife adjustment for slitting machines, in particular to a portable knife adjustment device for slitting machines. Background Art

[0002] Slitting machine is a mechanical device that cuts wide paper, mica tape or film into multiple narrow materials. It is commonly used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. Among them, non-woven fabric slitting machine is mainly used to cut wide rolls into various narrow rolls suitable for production needs.

[0003] The lower cutter of the existing slitting machine is adjusted manually when adjusting the width, that is, the lower cutter is manually adjusted to make the lower cutter slide on the air shaft to the position of the required width. However, there is a certain error in this process, which affects the accuracy of subsequent film slitting. In addition, different sizes of blades are required depending on the slitting materials, but the adjustment device is not convenient for adapting to blades of different sizes, resulting in unstable blade position adjustment. In view of this, we propose a portable slitting machine knife adjustment device to solve the existing problems. Utility Model Content
