Preparation of slitter cutter
1. Razor slitting
1.1. The razor slitting requires the film to travel in the correct direction to the winding section.
1.2. Adjust the photoelectric tracking to bring the film to the proper position.
1.3. Tension the film and attach the blade to the razor holder.
1.4. According to the specifications required by the instruction sheet, the sliding razor holder is cut into the razor groove under the film, and the blade edge and the edge of the sipe are required to be in contact with each other.
1.5 After adjusting the depth of the cutter, lock the razor frame screws.
2. Round knife cutting
2.1. Check whether the upper and lower knives are sharp and have no gaps, and vice versa;
2.2. Determine the number of knives (N+1) according to the number of product series (N);
2.3. Install the lower knife to adjust the width of the lower knife according to the actual width of the product;
2.4 Install the upper knife correctly. The flat side of the upper knife is aligned with the side of the lower cutting edge. The upper knife is aligned with the gap between the lower knife and the septum. Press the screws on both sides to make the upper knife enter the gap depth to about 2mm. The upper knife is attached to the lower knife and fastened. Finally, the screw on the left side of the upper knife holder is adjusted so that the whole knife holder moves 1-2 mm to the right side and is fastened.
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.

2. Lack of composite professional talents who understand manufacturing technology and process and know cutting process
In the manufacturing process of the slitting machine, different customers are often faced with different materials and requirements. If different manufacturers produce the same materials, the raw materials used are not the same chemical plant products, and the physical properties of the materials produced are not the same. When producing the slitting machine, it cannot be generalized. In the production process, the manufacturing process will change, especially in the size of the roll diameter and the thickness of the coating layer, the difference between the active roller and the passive roller and the wrap angle of the roller surface, etc. The lack of corresponding research talents in the field often leads to many waste products and defective products in the slitting process. Such composite talents should not only be familiar with the design and manufacturing process of the entire slitting machine, but also understand the different characteristics of different materials during slitting. Currently, it is very scarce in China, which leads to the current situation of domestic slitting machines.
