Slitting refers to the processing technology of rewinding the film of multiple unit patterns by cutting the position of the cutter to set the width and distance of the unit pattern.
In the industry, there is such an image metaphor, the early scuttering machine has a simple structure, the speed is about 100m/min, the mechanical friction mode of winding tension is manually controlled, and people refer to it as "telephone".
Later, after some modifications, the winding is controlled by clutch, single motor control traction and winding, the speed is about 200m/min, known as the "simulator".
Slitting process
Slitting process is the size does not meet the requirements of the use of materials by special cutting equipment processing into qualified materials process method, many packaging materials are used in packaging items before, often through slitting - printing - composite - slitting and so on multiple slitting, but each slitting process cutting methods are not the same.
Common cutting methods are:
1► Trimming :
The edge material reserved in the previous process is cut, which is mostly used for the processing of composite film and other materials.
2► Crop:
The wide coil is cut into multiple rolls of narrow size material.
3► sub-volume :
The large diameter material is divided into several small diameter materials, equivalent to rewinding and so on.
No matter which process is used for cutting, the material after cutting should reach the corresponding technical indicators:
1► Size requirement < /strong> :
Refers to the width and length of the cutting material.
2► Quality requirements:
The flatness of the coil, surface quality, etc.
Manufacturing and purchasing qualified cutting equipment not only to meet these technical indicators, but also must consider the following two factors:
1► Operating efficiency :
It mainly includes the working speed, stability and the difficulty of machine operation.
2► Economic performance:
Refers to the scope of application of the equipment to the material, the processing limit size, and the price of the equipment, energy consumption, etc.
Importance of slitting in packaging materials
China's paper packaging industry started in the early 1980s, but the development is relatively slow, at that time by technology and market restrictions, the materials used for packaging is limited to a few easy to process materials, because the packaging requirements are not high, the application range is not extensive, the processing equipment requirements are not obvious.
After entering the 1990s, with the improvement of packaging grade, the performance requirements of packaged items on packaging materials have become increasingly prominent, and many materials with special properties have appeared.
Because the characteristics of these materials cannot be destroyed during processing, this puts forward very demanding requirements for the performance of the equipment, especially the slitting machine, an important process in thin and light packaging.
On the other hand, with the gradual promotion of automated packaging equipment in the packaging industry, such as food packaging, cigarette packaging, etc., these automatic packaging machines are very picky about the quality requirements of the materials after slitting, which gives the slitting machine to high-grade, high-precision control has brought a broad space for development.
The use of domestic slitter
Due to the wide application of packaging materials and the increasing growth of characteristic materials, there are nearly 10,000 enterprises with a certain scale engaged in the production of packaging materials in China.
Before 1995, due to the constraints of domestic equipment manufacturing and other factors, the equipment of packaging materials processing enterprises is all the products of some foreign manufacturers, and the medium and high grade scutters they use are monopolized by a few foreign manufacturers.
Imported equipment is not only expensive, and the maintenance service is very inconvenient, some of the equipment introduced in the early stage has entered the frequent maintenance stage, some special materials are difficult to cut on the imported equipment.
Kloffer according to the development trend and process characteristics of packaging materials, absorb international advanced technology, with strong technical support, to the world's most advanced slitting machine as the goal, elaborate design, precision manufacturing, to create advanced slitting machine, to provide customers with a full range of services.
