Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a slitting mechanism which is convenient for changing blades. Background Art

[0002] Slitting machine is a mechanical equipment that can cut 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. Slitting machine is mainly used for: non-woven fabrics; mica tape, paper, insulating materials and various film materials. It is especially suitable for cutting narrow tapes (non-woven fabrics, paper, insulating materials, mica tape, film, etc.). When replacing the cutter of the slitting machine, a slitting mechanism that is easy to change the cutter is required.

[0003] For the current slitting mechanism, first clean and check the slitter to ensure that it is in normal working condition, prepare the required film and other necessary tools, adjust the parameters of the slitter according to the slitting requirements, install the appropriate blade on the knife disc of the slitter. If the slitter does not have a convenient knife changing function, you may need to use special tools to install and fix the blade. Adjust the position of the knife disc as needed to ensure the cutting position is accurate, turn on the power of the slitter, and start the slitter.

[0004] The traditional slitting mechanism cannot replace or adjust the blade in time, so the blade will gradually wear during the cutting process. As the blade wears, the cutting quality may decline, resulting in problems such as uneven slitting lines and edge burrs. The blade wear of the slitting machine will affect work efficiency and production capacity. When the blade becomes blunt, the slitting speed needs to be slowed down to ensure the cutting quality, which will cause the slitting machine to work slower, thereby limiting production capacity.
