Both CNC machine tools and packaging machinery need the same technology

Servo technology in the application of CNC machine tools, the servo system to accept the computer system command signals to control the operation and operation of CNC machine tools to ensure the stability, accuracy and rapidity of the operation of CNC machine tools, due to the speed and position accuracy of CNC machine tools Higher, so the servo system to a large extent determines the speed and accuracy of CNC machine tools.

During the operation of CNC machine tools, the spindle is used as the rotation coordinate, and the coordinates of the other chain are responsible for controlling the operation of the CNC machine tool. The Z axis and X axis are driven by the ball screw to drive the servo motor. The servo motor then drives the tool through the servo controller. To control the motor's movement and rotation. CNC machine tools use high-speed induction motors, apply vector control method, control the operation of CNC machine tools, control the induction motor by inputting the speed command, and input the speed command in the spindle controller to realize the control of the spindle speed of the CNC machine tool.

At the same time, using the CNC control system to give and feed the servo motor, the feed axis controls the position and speed of the CNC machine tool to achieve more accurate trajectory processing. The photoelectric encoder is used to detect the position, the CNC machine tool coordinate axes are respectively set with the displacement and speed detection equipment, and the rotary transformer is used to detect the speed of the spindle motor of the CNC machine tool, so that the feed system and the index meter are synchronized and the closed loop feedback control is realized.

With the rapid development of AC servo technology, its application in the packaging machinery industry will become more and more extensive. Traditional packaging machinery production mainly uses brakes, clutches and single motors to control the interruption, stop and start of related mechanical equipment. For the packaging machinery industry, the speed of packaging processing is mainly controlled by high-frequency synchronous positioning actions. Therefore, the impact is likely to occur in practical applications, resulting in a large area of wear of the friction elements of the brake or clutch, thereby reducing the movement accuracy and work characteristics of the packaging machine, and failing to control the high-accuracy and high-frequency synchronously.

If the transmission chain is relatively long or the transmission ratio is variable, controlling the entire driving process by a single motor and replacing and adjusting the transmission components in time will increase the production cost of the packaging, and the operation and control period will be long. The application of AC servo motor in packaging machinery can be maintenance-free, with high responsiveness and constant torque.

After the command pulse is applied, when the motor rotates, the voltage command signal is output from the inverter according to the command pulse of the deviation counter. The number of command pulses determines the rotation angle of the motor. The motor rotation speed is controlled by the pulse frequency. The motor controller is used to realize the AC servo motor. Operation and drive. At the same time, the position feedback encoder reduces the dwell pulse in the deviation counter and sends a feedback pulse. When it is reduced to zero, the AC servo motor stops rotating.
