How to choose a paper tube cutter blade

How to choose the paper tube cutter blade is based on the difference in the type and thickness of the cut data. We must first understand the classification and scope of the different blades. Generally, the slitting method of the paper tube cutter blade includes square knife slitting and round knife slitting.

The square knife is cut like a razor. The blade is fixed on the tool holder of the paper tube equipment. When the data is running, the knife is dropped, so that the knife cuts the data longitudinally to reach the slitting intention.

The square paper tube cutter blades are mainly divided into single-sided blades and double-sided blades.

Single-sided inserts are better for thicker, stiffer, thicker slitting films, because the hard-blade does not simply break the displacement of the paper tube machine at high speeds, ensuring product quality.

The double-sided inserts are softer and more suitable for thinner data, so that the flatness of the edges of the film is ensured and the life can be extended together.

Square cutter slitting is usually divided into two types: slitting and hanging slitting: Grooving slitting is when the slitting machine is running on the sipe roller, the cutter is dropped in the groove of the sipe roller, and the data is longitudinally cut. At this moment, the data has a certain wrap angle in the sipe roll, which is not easy to appear drifting. However, regarding the hanging and slitting, its drawback is that it is more troublesome for the knife. Suspended slitting is when the data passes between the two rollers, the blade falls to cut the data longitudinally. At this moment, the data is in a relatively unstable condition, so the cutting accuracy is slightly worse than the cutting die, but this cutting method Convenient for the knife and easy to operate. The circular knife is mainly divided into two methods: upper and lower disc cutter cutting and round knife kneading and slitting. The upper and lower disc cutters are widely used, and the paper tube machinery factory has two types of tangent slitting and non-tangential slitting. The tangent is cut into the data from the tangential direction of the upper and lower disc cutters. The non-tangential slitting is that the data and the lower disc cutter have a certain wrap angle, and the lower disc cutter falls to cut the data. The use of round knife kneading in occupations is not very common. It consists primarily of a pneumatic slitting knife that is synchronized with the speed of the data and has a certain angle of the bottom roller and convenient conditioning.
