Material metering
The measurement of powdery materials is commonly used in the way of screw measurement. The purpose of measurement is achieved by the number of turns of the screw rotation. In order to improve the accuracy of measurement, the speed of the screw is required to be adjustable, the position positioning is accurate, if the AC servo motor is used to drive the screw, the advantages of high control accuracy and good moment frequency characteristics of the AC servo motor can be used to achieve fast and accurate measurement. For the measurement of viscous materials, an AC servo motor can be used to drive the gear pump, and the measurement can be carried out through the meshing of a pair of gears of the gear pump.
Horizontal sealing device
In the bag-making automatic packaging machinery, the horizontal sealing device is an important mechanism, which not only requires accurate positioning, but also requires that the linear speed of the horizontal sealing wheel is equal to the speed of the film supply when the transverse sealing table is sealed, and after the horizontal sealing wheel rolls, the rotation speed of the horizontal sealing wheel should increase, that is, it is separated at a faster speed.
The traditional method is achieved by mechanical means such as eccentric wheel or crank guide rod mechanism, which is not only complex, low reliability, but also very troublesome to adjust. If the AC servo motor is used to drive the horizontal sealing wheel, the excellent motion performance of the AC servo motor can be used to meet the requirements of the transverse sealing through the non-constant speed movement of the AC servo motor, so as to improve the quality and efficiency of the work.
Feeding materials
There are two types of working methods for packaging machinery to feed materials: batch type and continuous type.
In the intermittent feeding method, such as in the intermittent bag-making and packaging machine, in the past, the feeding of the packaging film mostly adopts the crank connecting rod mechanism intermittent pulling method, which is not only complex in structure, but also difficult to adjust. If the AC servo motor is used to drive the belt roller, the distance of each operation of the AC servo motor, the running time and the stopping time can be set in advance in the controller, and the excellent acceleration and positioning performance of the AC servo motor can be used to accurately control the length of the supplied film. Especially in the control system with color mark correction device, the deviation signal detected by the color mark detection switch is transmitted to the AC servo motor through the controller, and the excellent acceleration performance and control accuracy of the AC servo motor can make the deviation be quickly and accurately corrected.
In the continuous feeding method, the excellent acceleration performance and overload capacity of the AC servo motor can ensure the continuous and uniform feeding of materials.
