Application of Stepper Motor for Filling and Sealing Machine As China's economy develops rapidly, China has gradually become a processing center in the world. At the same time, our country's mechanical products are also developing rapidly. The author mainly introduces the application of samsr stepper motor in filling and sealing machine.
Filling and sealing machines have a wide range of applications in cosmetics, light industry (daily use chemicals), pharmaceuticals, and food industries. These industries generally choose hoses as packaging containers. The equipment can fill ointments, creams, gels, or viscous fluids inside the hoses, and then hot-melt the end of the hoses and print the code. At the same time, pruning and shaping produce finished products.
Stepper motor speed control is achieved by the input pulse frequency speed. When the frequency of the pulse is reduced, the speed of the stepping motor decreases; when the frequency increases, the speed increases.
In packaging machinery, using a stepper motor to drive the actuator not only makes the packaging machinery simple, convenient to adjust, increases in reliability, but also greatly improves accuracy.
Second, the application of stepping motor in filling and sealing machine
1. Work flow bins (hose containers) → automatic tube management → labeling and positioning → hose internal cleaning (options) → filling → tail hot melt welding → press-fitting sealing, typing code → hose positioning → cutting → finished products discharge.
2. The working principle is controlled by PLC program. Automatic tube, color label positioning, air cleaning tube space, filling nozzle deep into the tube, heating of the inner wall of the tube wall, heating of the tube wall (cooling of the cooling water machine), hot melt pressure Coupling code, tail cut, finished product discharge. The parameters are displayed digitally.
In the filling and sealing machine, the most critical step is the positioning of the hose. This product uses Yamatake's stepper motor, with precise positioning and high control accuracy.
Set the stepper motor speed in advance. The color standard mode is equipped with a photoelectric switch, and the photoelectric switch detects the position of the color mark. When a color mark is detected, a control switch signal is issued. After the stepping motor presses the signal, the rotation stops. After a certain time delay, the rotation is performed again and again. Accurately position according to the position of the color mark.
