I. Overview 1. Slicing process and its characteristics Slitting process is a process method for processing a material-specific cutting equipment that does not meet the requirements of use into a qualified material. In the flexible packaging industry, this special equipment is called a slitting machine. .
Many packaging materials are often subjected to slitting-printing (or coating)-composite-slicing, etc., before they are used for packaging. However, the cutting methods are not the same in each slitting process. The methods are: (1) trimming, cutting off the process trimmings reserved for the upstream process, and more for the processing of composite membranes, etc.; (2) cutting, slitting the wide web into multiple rolls, narrow gauge dimensions Materials; (3) Sub-volume, dividing large diameter material into several small volumes of material, equivalent to rewinding; and so on. These methods are sometimes used in combination. Regardless of the kind of process used for cutting, the materials after slitting should meet the corresponding technical specifications: (1) Size requirements (refer to the width and length dimensions of the slitting material, etc.); (2) Quality Requirements (roll flatness, surface quality, etc.).
Manufacture and purchase of qualified cutting equipment not only meet these technical specifications, but also must consider the following two factors: (1) Operational efficiency, which mainly includes the working speed, stability, and ease of operation of the machine; (2) Economic performance refers to the scope of application of equipment to materials, the limit of processing dimensions, and the price and energy consumption of equipment.
2. The importance of the slitting machine in packaging materials China's flexible packaging industry started in the early 1980s (here mainly refers to plastic packaging; paper packaging began earlier, but the development is relatively slow), was restricted by technology and market The packaging material is limited to a few easily processed materials (such as PE, PVC film, etc.), because at that time the packaging requirements are not high, the scope of application is not extensive, and the requirements for processing equipment are not obvious.
After entering the 1990s, with the improvement of packaging grades, the performance requirements of packaging materials for packaging materials have become increasingly prominent (requiring materials with barrier properties, shading, etc.), and many materials with special properties have emerged (such as the use of shading and the surface High quality aluminum plating material, high elongation CPP film, etc.) Since the characteristics of these materials cannot be destroyed during the processing, this places very stringent requirements on the performance of the equipment, especially the important process in the soft plastic packaging, the slitter.
On the other hand, with the gradual promotion of automatic 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 slitting materials, which gives slitting machines high grades. High-precision control brings a broad space for development.
Second, the use of domestic Slitter due to the extensive use of packaging materials and the growing number of characteristic materials, currently there are nearly a hundred companies in the packaging materials production and processing enterprises.
Prior to 1995, due to the constraints of domestic equipment manufacturing and other factors, the packaging material processing companies' equipment was all foreign manufacturers' products. The medium and high-grade slitting machines they used were monopolized by a few foreign manufacturers. High-end German CommScope, UK Atlas, etc. (The winding tension of this type of equipment is automatically controlled by taper method with a speed of 300m/min or more), and mid-range products are Japanese and Taiwanese products (speed is about 200m/min. ) Imported equipment is not only expensive but maintenance services are extremely inconvenient. Some of the equipment introduced early has entered a phase of frequent maintenance, and certain special materials are difficult to cut on imported equipment.
Domestic slicing machines started late. In 1986, Wuxi Beiren Xiemin Printing Machinery Factory took advantage of the strength of scientific research institutions to refer to the more advanced equipments of Japan and other countries to overcome the constraints of conditions and successfully developed the first Taiwan-made light control cutting machine -GFQ1100 type, this equipment was soon widely used by the industry, welcomed by users, since then launched the domestic manufacturing Slitter voyage.
After 90 years, it entered the information age. The manufacturing industry is also facing new technologies such as digitalization and industrial automation. Precise foreign accessories and advanced control technologies have created tremendous impetus for the processing and manufacturing of the slitting machines. Wuxi City Beiren Xiemin Printing Co., Ltd. Based on the development trend and process characteristics of the materials, the machinery factory absorbs advanced international technologies and relies on the Beiren Group to have strong technical support. With the goal of the world's most advanced Commer, etc., it is designed and manufactured with precision, and manufactured in 1997. The GFQ1300, a fully-adjusted slitter with proprietary intellectual property rights (Patent No.: ZL992 28014.1), has ended the history of high-grade slitting machines relying on imports from China. Over the past few years, dozens of companies engaged in material production, aluminizing, cigarette packaging, etc., in Zhongshan, Anhui, Hefei, Anhui Province, and Huaiyin, Jiangsu Province have agreed that the equipment is among the best in the world.
A company in Shanghai is a Japanese-owned company. It knows more about international slitting machines. The company already has several foreign slitting machines. When it expanded production at the beginning of the year, it initially had doubts about domestically-made slitting machines. After conducting many tests on the products of the Beiren Xiemin Printing Factory, and conducting discussions with the experts of the Beiren Association of People's Livelihoods, they finally gave them the order to manufacture the cutting machines with confidence and manufactured them. The product gives a very high rating.
Third, the performance characteristics of domestic high-end slitting machine GFQ series automatic high-speed slitting machine manufactured by Wuxi Beiren Xiemin Printing Machinery Factory is a machine, electricity, light and gas integration, with high speed (200-500m/min ), complete specifications (600-2200mm), a wide range of uses (film, paper, aluminized materials, etc.), high precision (digital automatic control) and other notable features.

3. The slitting knife has two structures: flat blade and round blade. It is convenient to use and meets the multi-purpose use of paper and film materials on the same equipment. The main electrical appliances, pneumatics and standard parts are imported brand-name products. Stable and reliable performance.
4. The price of this machine is only 1/3-1/5 of the imported equipment of the same level, and the performance price is relatively high.
The technical performance of the automatic high-speed slitting machine manufactured by Wuxi Beiren Xiemin Printing Machinery Factory has been at the leading position in China and has reached and surpassed the advanced level of similar products in certain aspects. This factory has set an international brand name as its goal. To carry out technological innovation, the research and development and manufacturing capabilities of the cutting equipment have been formed. Based on the achievements, new products are continuously introduced. The working speed is increased from 300m/min to 500m/min. The machine size has been extended from 1300mm basic size to small format computer paper from 600mm to 2200mm wide material slitting. . Some domestic large-scale packaging material manufacturers have invited them to carry out maintenance and reconstruction for the early imported equipment, and they have designed and manufactured a series of special equipment with special performance specifications (such as film slitting, etc.), which not only brings about great results to the company itself. The economic benefits have contributed to the development of the packaging industry in China.
Fourth, the development trend of slitting machine in the industry has such an image metaphor, the structure of the early slitting machine is simple, the speed is about 100m/min, the mechanical friction of winding tension is manual control, people call it "the telephone "; Afterwards, after some transformations, winding and clutch control, single motor control traction and winding, the speed of 200m/min or less, known as the "simulation machine"; Beiren Association Printing Factory automatic high-speed points Cutting machine, the use of digital automatic control, the speed of 300m/min above, just like the "digital machine" in the field of modern communications.
After entering the new century, digital informatization has spread across various industries. With China's accession to the WTO, the Slitter will also be moving in the direction of higher speed and higher precision. Wuxi Beiren Xiemin Printing Machinery Factory First, to strive for top-notch "for the purpose, is stepping up to study the control technology, the speed and accuracy of the signal processing, and the improvement of the traditional cutting edge cutting methods faced by the more upscale cutting machines. They ice, guidance, and cooperation to work hard for the brilliant future of the packaging industry!
