During the production and operation of the slitting machine, sometimes we may find that the finished product has a certain degree of bending, which causes the product to be unqualified and suffers huge losses to the manufacturer.

In fact, this situation is definitely a problem in the production process, and a large part of the loss can be avoided if it is discovered in time. Therefore, in the operation of the slitting machine, always pay attention to the quality of the finished product. If there is something wrong, it should be shut down immediately for inspection. Below we will explain the five reasons why the product bends on the slitting machine.

First of all, the first and most common reason is that the raw material sheet itself is bent, and the direction of the slitting is not handled properly during the slitting, which causes all the finished products to be bent.

In this case, we should install blades that eliminate bending on both sides of the slitting machine, so that a small part of the plates on both sides can be wasted and most of the plates can be saved. However, in the final analysis, we must carefully select raw materials to avoid substandard raw materials.

The second is caused by the presence of burrs on the edge of the blade. When the blade is slitting, if there are burrs on the surface, the edges of the cut sheet will be uneven and bend.

The third is the bending caused by the uneven gap between the upper and lower blades of the slitting machine. If the gap between the upper and lower blades is not uniform, the slitting line will change, and the extent of extension will be greatly increased, resulting in bending.

The fourth is the improper tension control during slitting, which is sometimes large and sometimes small. The uneven force on the baffle during rewinding causes the bending phenomenon to occur.

The latter reason generally does not appear to be that the slitting machine itself is not firmly fixed, which causes the machine body to tremble in operation, which leads to the bending of the plate.

The above five points basically cover the reasons for the bending phenomenon of the product, and I hope it can be helpful to everyone. The operation steps should not be ignored, and the safety production should be kept in mind.

What we have to say when using a slitter is to operate the equipment correctly and reasonably, which is a prerequisite for ensuring the long-term stable operation of the equipment. Any excessive use and improper operation of the equipment will affect the equipment, and the characteristics of the use of different slitting machines are different.

The maintenance of the slitting machine is mainly cleaning, lubricating, tightening, and adjustment and replacement of wearing parts. Cleaning is mainly for the heating parts of the equipment. There are many displacement parts in the slitting machine parts, and they all need regular lubrication to prevent excessive wear. For stressed parts, regular tightening and inspection positions are required. Wearable parts such as brakes and wire passing mechanism should be adjusted regularly and overhauled and replaced.
