About paper cutting technology (2)

Self-diagnosis system:

The continuous monitoring of all functions of the machine paper cutter, if there are any errors or abnormalities, there will be an immediate signal display, clearly displayed in words, so that, sometimes even through a telephone, it is possible to eliminate the malfunction as soon as possible.

In addition to various standard features, Polar offers many ways to solve specific cutting applications.

The Polar Autotrim is the world's first high-speed paper cutter that automatically eliminates waste and automatically collects small cutting products on the supporting worktable support board. Autorim is the most efficient advancement in high-speed cutters since the computer programmed control of the cutting machine.

The advantage is that the operator does not need to manually remove the transportation waste while cutting, and when the waste is cut out, the desktop can remove the waste by opening the front table of the machine paper cutter. This feature is optional to increase production by up to 30%.

Autotrim has the following features:

1, there is a certain starting position.
2, in the cutting cycle: rely on the program to open the front table desktop, scraper moves up, waste scraping into the waste box or sucked into the suction duct.
3, The back gauge pushes the material to be cut to the front workbench desktop or auxiliary worktable support board.
4. The cutting machine is ready for the next cut, and the material has been placed on the supporting workbench support board.

Swing back gauge, inclined back gauge and Fixomat

There are many special options available to support the operator for high-precision cutting. They can align the printed image translation with the cutting line, compensate for tangible or less cuts, or simulate the imitation of the paper on the registration point marked on the printing press and the registration machine.

Tooth claw type loading system

This optional accessory is attached to the back table of the machine paper cutter. It will stack multiple orders from the paper cutter, the loading table top, the air pressure paper board or other equipment. Lift it and place it on the back table of the rear table of the paper cutter. The premise is that there is a retractable side gauge on the cutting machine. The fangs grippers can hold the paper tightly and precisely place a certain number of sheets of paper accurately on the paper cutter.

Optional Accessories Option Downholder Limiter/Fixomat

Limiter The downholder
Fixed push-down device This press-down device can smooth some of the more difficult materials such as a curled paper stack or plastic film, and excellently lays neatly and perfectly on the back gauge.

Such as: curled pile of paper or plastic film on the back gauge "not obedient" material.

Automatic clamping press force adjustment device

This last option for a very efficient high-speed paper cutter automatically adjusts the paper clamping pressure. (Today, this job is done manually.) When cutting long and short ends, computer programming can be automated. According to the need to adjust the pressure compensation.

Electronic probe: According to the number of paper and the cutting length, any suitable cutting pressure will automatically adjust to the appropriate clamping pressure.

A specific material only needs to be clamped for a single press.

Advantages: Constant high cutting quality, no damage to the material, extended knife life.

In front of the knife limiter press device (Downholder)

The patented cutter of this latest patented design can be used on the patented part of the cutting machine to prevent slipping or misalignment when cutting small-size products.

Knife: Logically, the modern knife, no doubt, is demanding high performance. Different manufacturers have different tool grades due to different requirements, and the range of quality selection is also very large.

Standard knife: It can be used under a variety of normal working conditions without frequent grinding.

High speed steel knife:
This is a composite steel knife with a special alloy.

It has been proved that this kind of knife is the safest and the best in performance when it is used to cut difficult-to-cut and uneven paper.

Carbon steel knife:
This grade knife has a particularly sharp knife edge that resists abrasion. As long as it is used in the right place and used correctly, it performs 20 times as much as a standard steel knife.

Knife quality:
The knife with different quality should be selected according to different use occasions. For economic reasons, it is really necessary to compare the costs within a certain period of time.

Key points: For any special tool, it is necessary to use it well, so the local must have sharpening equipment.

The figure shows the geometry of the cutter and the average angle is 24 degrees. The angle of the knife may also vary depending on the quality of the paper and the card. Carbon steel blades are twice as steep or angled.

This chart illustrates the performance of various grades of knife under normal conditions. Of course, the actual performance is related to the specific working conditions and applications.

Toughness is the ability of a material to withstand repeated machine and transport tosses. Tenacity is the ability of a material to withstand mechanical action.

Anti-abrasion ability - is the ability of the knife edge to withstand surface wear and maintain knife edge sharpness in long-term use.

Abrasion resistance - refers to the ability to use long after grinding (ie, to reduce the ability to repeat the grinding), a special process and equipment to ensure.

peripheral equipment:
All of the previous demonstrations focused on the process and performance of high-speed cutters.

However, this performance has to be achieved, and the material flow must be properly arranged by properly preparing the cutting material and using peripherals of the cutter.

Peripheral equipment includes the following parts;

Lift paper machine

Cutter machine

Conveyor

Buffer stacking equipment

Automatic loading and unloading equipment (Transomats)
