Maintenance and maintenance of the slitter:
Before use, the main parts of the automatic slitting machine should be inspected and filled with lubricating oil. When inspecting the disassembly and assembly automatic slitting machine, it is strictly forbidden to use unsuitable tools and unscientific operation methods; every two weeks to the machine Make a comprehensive cleaning and inspection; if the automatic slitting machine is stopped for a long time, all the bright surfaces must be wiped clean, coated with anti-rust oil, and covered with a plastic sleeve to cover the whole machine. If the automatic slitting machine is deactivated for more than 3 months, the anti-rust oil should be covered with moisture-proof paper; after the work is completed, carefully clean the equipment, and wipe the exposed friction surface and add lubricant.
The basic knowledge of the slitting machine and its development process --
Basic knowledge and development of slitting machine
In the process of slitting, the stable tension system is an important indicator to ensure the quality of the product. It controls the mutual tension between unwinding, drawing, slitting, winding, etc., so that the slitting material is always in the cutting process. A steady state. If the tension is properly controlled, it can avoid the deformation and drift of the raw materials during the process of speeding up and slowing down the machine. Generally, the unwinding tension is slightly larger than the sum of the reel tensions. Most of the previous slitting machines use magnetic powder clutch to control the tension, but the magnetic powder clutch speed can not be high. It is easy to cause high-speed friction of the magnetic powder during operation, which causes high temperature and shortens its life. In severe cases, it will be stuck and the machine operation will be blocked. With the development of science and technology, the use of servo drive technology, most of them now use vector variable frequency motor to control the tension system of the slitting machine. The automatic detection of the pendulum roller makes the man-machine interface intuitive, the tension system is more stable and reliable, and easy to operate.
Domestic cutting machine development status and outlets ---
First, the status quo of domestic slitting machine
At present, the domestic use of the slitting machine is mainly divided into several stages, and the first stage is mainly used for the main line slitting as one slitting. One slitting is mainly provided to downstream deep processing enterprises, and the downstream customers are divided into secondary slitting or three slitting. The film making manufacturers of this meeting are mainly cut into one slitting, with the competition of film forming enterprises in recent years. Intense, in order to provide better services to downstream customers, film companies have also added a second cut. In one slitting, the most used brand is CommScope, followed by Atlas, and the Japanese slitter is rarely used in one slitting. With the rise of domestic equipment manufacturing industry in recent years, domestic slitting machines have a certain foothold in a slitting process. Of course, compared with foreign slitting machines, there is still a certain gap in domestic slitting machines. From the user's point of view, I personally think that there is a certain misunderstanding, mainly because of the lack of deep understanding of the slitter market. Everyone knows that there must be a performance price ratio when purchasing a piece of equipment. In fact, the performance and price ratio of the above mentioned brands are not necessarily the best. Some people in the United States have done such an experiment. The above-mentioned brand slitting machine is compared with the Japanese Knife cutting machine. When the same film material is cut, the result is that Japan's Kataoka wins, mainly in terms of stability and speed, speed reduction and non-stretching. Japan's Kataoka has shown superior quality and its price is lower than the above brands. Unfortunately, in the domestic film-making enterprises, no one slitting machine used Japan's Kataoka slitting machine. It is a pity that domestic companies have bought foreign second-rate equipment at the highest price. I have researched the US market. Japan's Kataoka has a high market share in the US market. I believe that with the increase in market demand and fierce competition, domestic companies will come out of this misunderstanding and re-recognize the market of slitting machines. Compared with the first slitting, the third slitting and the one slitting, the status quo of the domestic slitting machine is diversified. One slitting is mainly the importing equipment to play the leading role, while the secondary slitting and three slitting fields are in the field. The domestic market has its own magical powers, including Europe, Japan, and Taiwan. In recent years, the domestically produced slitting machines have gradually replaced the trend of foreign brands, resulting in the following results:
1. Foreign advanced cutting technology has gradually flowed to China;
2. The rise of domestic manufacturing;
3. Popularization of advanced control technology;
4, the low cost of manufacturing causes the price of the slitting machine to be low;
The above various reasons have jointly promoted the domestic film-making enterprises to choose domestic slitting machines. As time goes by, I believe that the domestic cutting opportunities become more mature and the performance is better.
