Matters Needing Attention When Enterprises Choose Paper Cutter

Paper cutting machine is necessary for printing enterprises.

equipment

When choosing a paper cutter, we should pay attention to the following aspects.

1. security

The paper cutter is different from other mechanical products. It belongs to the four level risk machine with the highest risk stage.

When selecting the paper cutter products, we must focus on the safety and reliability.

For example, is there any anti dropping device for paper presser? Can the movement part be equipped with a full seal safety cover to avoid the accidental damage of parts and components, and whether there is any infrared electronic control system and electronic safety knife lock in the process of operation?

2. mechanical construction

The earliest mechanical paper cutter was used for pressing paper.

Spring

Pressure, pushing paper with slider type structure is relatively simple in structure and easy to debug and maintain. However, the pressure of paper pressing is small, and the cutting accuracy is poor. It can not meet the requirement of high degree printing for paper cutting accuracy, and can not meet the requirements of medium and high grade packaging printing products.

In five and 60s of twentieth Century, there was a double track cutter with no grooves in the working platform, which was gradually replaced by the dovetail slot structure of the German Paula company.

At present, some mechanical manufacturers in China also produce double track cutter, but their overall structure and performance are not as advanced and applicable as those of Paula's paper cutter.

The paper cutter with double guides is very difficult to adjust the accuracy, and the price of changing the guide way after wearing is more expensive, but the operation accuracy of the equipment is high.

The accuracy of the cutter is easy to adjust, and the plug iron is only replaced after wearing, but the accuracy is slightly lower.

When purchasing the paper cutter, the printing enterprise should choose two guide cutter or dovetail slot cutter according to its own needs and the actual conditions of the products to be processed.

3. working efficiency and cutting accuracy

The efficiency and cutting accuracy of the paper cutter are in the printing industry.

Choose

One aspect of the paper cutting machine is more consideration.

In this respect, the microcomputer controlled paper cutting machine is much better than the ordinary paper cutter.

The paper pushing machine of ordinary paper cutter should be controlled by buttons and handwheel fine-tuning in the process of moving and retreating. The labor intensity of the operator is large and the working efficiency is low.

And the computer program controlled paper cutting machine is programmed to optimize the cutting process and improve the working efficiency.

In pursuit of efficiency, users also require cutting the products with higher dimensional accuracy with the fastest cutting speed.

Therefore, the most advanced cutting machines in China now use the most advanced ball screws and linear guides.

Its characteristics are smooth pmission, high positioning accuracy and small accumulative error. It does not need to adjust the movement clearance for a long time, and eliminates the problem of cutting accuracy due to the different wear levels of the slideway and guide rail after using a common screw rod and guide rail for a period of time.

4. energy consumption comparison

The same type of paper cutter should be compared on the whole machine's power.

The power of the motor is not only related to the power consumption.

Because of the reason of precision matching in the process of machine assembly and assembly, the motor with larger power has to be selected. It is actually a method that can not be processed in mechanical process and assembly but must not be taken into account.

5. after-sales service

When choosing the paper cutter, the after-sales service of the consumer factory is also required.

Conduct

Comprehensive trade-offs.

The distribution of a good manufacturer in after-sales service outlets will consider whether it can enable customers to receive satisfactory service and technological support in the shortest time. The quality of service before sale, after sale and after sale is a detailed manifestation of the comprehensive ability of paper cutting machine manufacturers.

Besides, the following details should also be paid attention when applying the paper cutter.

The first is the choice of cutting edge angle.

This is a very important part of the cutting work.

A good paper cutter must have a good blade and sharpening process.

However, a lot of paper cutter users often neglect this point. As a result, the blade grinding mode, method and angle are not correct, and the cutting accuracy is not enough. What is more serious is the increase of impact force during cutting, resulting in loosening of the safety screws and even breakage, resulting in Mechanical damage eventually.

In addition, the paper cutting machine has a wider range of cutting data and will encounter different problems in the process of cutting.

For example, aluminum foil label and carbonless copy paper form are easy to appear indentation when cutting, while PVC and magnetic card will appear to be pressed in paper cutting, which will cause waste disposal.

These problems can be adjusted by the automatic pressure reducing valve to adjust the pressure of the presser, improving the blade sharpening angle and blade material, such as high speed steel and cutting pmission system.
