What is the development history and coating process of tape coating machines? Let me talk to you today:


my country introduced tape machinery in the 1980s. At that time, the development of my country's mechanical manufacturing industry was relatively backward. The initial production speed of tape coating machines reached dozens of meters per minute. After more than 30 years of development, my country's tape machinery industry also eliminated a group of batch The relatively backward device is approved to gradually introduce new devices to help the healthy development of my country's tape -based mother roll industry. As of now, the production speed of the coating machine on the market is still large. With the improvement of my country's productive forces, a group of relatively weak devices have been eliminated.


The tape coating machine has a large size. The coating machine on the market not only has different width, but also has a difference in length due to the different design speed. At present, the width of the domestic coating machine is 500mm, 1000mm, 1300mm, and 1600mm. Among them, 1300mm is common, accounting for about 80%of the nation's usage, 500mm and 1000mm. The coating machine has gradually flourished in recent years. The length of the coating machine is 30-40 meters (design for drying glue).


There are two coating processes of tape coating machines, which are coating and scraper coating. The scraper coating is a traditional coating process. Its advantage is that it can obtain higher smoothness and gloss; the disadvantage is that the requirements for the original membrane are higher and the speed of the coating is relatively slow. As a coating process that has just emerged in recent years, its advantages are: low requirements for the original membrane, faster glue, and coating that can adapt to high -solid content; the disadvantage is that the coating volume can be adjusted to adjust the amount of coating amount. The range is small, the measurement stick is easy to damage, and the quality of glue is high. Each process has the flash point of each process. The two processes can only coexist and cannot be eliminated.


Occupation speed: different craftsmanship, different speeds


The production process of the coating machine is divided into line rod coating process and scraper coating process. Generally speaking, the coating of the thread machine is faster than the production speed of the scraper coating. According to data, the current production speed of the line rods is 250-260 meters per minute, 280-290 meters/minute, and part can be more than 300 meters per minute; the production speed of the scraper coating is 220-230 meters/minute of 220-230 meters/minute. , 180-190 meters/minute, 150 meters/minute, and even some old lines are about 100 meters per minute. Therefore, the production capacity of each coating machine is very different.
