Reasons, countermeasures and effects of BOPP film slitting quality ---

nine. Scratch
      Whether the slitting and scratching can be compared and determined by the film surface before and after the slitting, there are various reasons for the scratching of the membrane surface, and the analysis should be based on the appearance of the scratch, such as short-line scratching. The difference of the speed ratio of each drive roller exceeds the process setting requirement, and it needs to be carefully tested and adjusted. If the film surface scratch occurs continuously, the film on the slitter should be inspected for whether it touches the fixed object or cuts each. Whether the roller adheres to dirt such as fine sand grains scratches the film surface.
Scratch is the appearance quality problem of the film, which directly affects the quality appearance of the deep-processed product. Therefore, it is not allowed to exist in the film quality control standard. The slitting process finds that the scratching problem must be carefully checked and quickly eliminated. Since the scratch on the film surface is an irreversible appearance quality problem, it is not allowed to operate the disease when the film surface is scratched, so as to avoid the continuous occurrence of the problem.

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.

three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:

2. Automation control part: At present, the automation level of the slitting machine produced in China is still at the middle and lower level. Although the domestic control of the original device has been widely used and the price is lower, the domestic slitter manufacturers are far away in use. It lags behind the level of developed countries, especially in the control system, and the lack of organic combination with the structure of the slitting machine and the material to be cut. At this level, most of the domestic slitting machines still stay on the thick lines. The rigor and rationality of the cutting machine control system has not been fully understood. I personally think that the domestic slitting machine manufacturers should start from the above several directions, and find out the method that meets the cutting and cutting principle of the slitting machine and can maximize the use of the functions provided by the hardware.
