Cutting Mode Of Paper Slitter

- Mar 26, 2016-

Slitting machine in the process of paper slitting can be divided into three ways: flat knife slitting, circular knife slitting, extrusion slitting.

The company is located in:

1, flat knife slitting: that is, like a razor, the single-sided blade or double-sided blade fixed to a fixed turret, the knife will fall in the material operation process, the knife will cut the material longitudinally to achieve cutting purpose.

The company is located in:

Slitting knife cutters in two ways :: one is slotting slitting; one is vacant slitting.

The company is located in:

Slitting slitting material is running in the Slit roll, the knife falls in the Slotted groove, the material cut longitudinally, then the material in the Slit roll have a certain angle, difficult to drift phenomenon; subdivision Cut the flow of PP film or a narrower edge of the film, the paper slitting machine commonly used in this way, can improve the cutting efficiency, but the dangling, its disadvantage is more inconvenient to the knife.

The company is located in:

Hanging slitting is the material between the two rollers, the razor will cut the material longitudinally cut, then the material is in a relatively unstable state, so the cutting accuracy than the cutting moderation slightly worse, but this cut Convenient way to knife, easy to operate. Cutting knife is mainly suitable for slitting thin plastic film and composite film.

The company is located in:

2, round knife cutting: Round knife cutting can be divided into tangential and non-tangential cutting.

The company is located in:

Tangential slitting of materials from the tangential direction of the upper and lower disc cutter slitting, the slitting knife more convenient, the upper disc knife and the lower disc knife according to the cutting width requirements, it is easy to directly adjust the position. Its disadvantage is that the material is prone to drift at the slitting, so the accuracy is not high, now generally do not.

The company is located in:

Non-tangential slitting is the material and the lower disc knife has a certain wrap angle, the lower disc knife falls, the material cut. This way of cutting can make the material not easy to drift, cutting precision. But the knife is not very convenient, the next disc knife installation, you must remove the entire shaft. Round knife slitting for cutting thicker composite film and paper category.

The company is located in:

3, Squeeze: Slitter Slitter in the domestic machine is not uncommon, it is mainly synchronized with the material speed and the material has a certain angle at the end of the roller and easy to adjust the composition of the air knife. This way can not only cut slitting thin plastic film, you can also cut thicker paper, non-woven fabrics. Is a more convenient way to cut. Slitter slitting is a way of development.
