German packaging machinery, especially beverage, beer filling machinery and food packaging machinery, have characteristics such as high speed, complete sets, high degree of automation, and good reliability. Their beverage filling speed can reach up to 1200 bottles/hour, and cigarette packaging can reach 12,000 sticks/minute. Increasing the machine's rotational speed is a complex issue; the faster the speed, the lower the unit production cost, but the floor space usage also increases accordingly. Moreover, there are limits to the speed of electric motors, so it's not possible to increase the speed arbitrarily. Generally speaking, increasing the rotational speed by 15% to 20% will bring about a series of complex problems.
