Automatic sealing machine is to seal the cartons with instant adhesive tape, which is economical, efficient and easy to adjust. It can seal the cartons up and down at one time. Of course, the adhesive tape used can be the company's printing tape, improve the product image of the enterprise, and it is the necessary packaging equipment for automatic packaging enterprises. So for such a packaging equipment, what is its electrical control, do you know?
The automatic sealing machine system is controlled by PLC. At present, the control function and application field of PLC are expanding continuously, and various complex control tasks such as simple logic control of single equipment, motion control, process control and distributed control are realized. Its ability in analog control, digital operation, man-machine interface and industrial control network has been greatly improved, and it has become the mainstream control equipment in the field of industrial control.
The operation process of the automatic sealing machine system is mostly simple sequential control. The input signals are collected by photoelectric and mechanical switches, and the output signals are processed by PLC to control the operation of various solenoid valves. The difficulty lies in the height control of the lifting body. Because the height of the box is not fixed, the height of the lifting body should be adjusted according to different boxes to adapt to the smooth completion of the sealing. In this system, we use barcode scanner to complete this step. Barcode scanner is installed at the front of the station. After the barcode signal is processed, the data is sent to PLC, which corresponds to the height of various boxes (the height is set on the touch screen); at the same time, the encoder at the motor side will feed back the pulse and compare it with the set height in PLC, so as to drive the asynchronous motor to adjust the lifting mechanism Adjust to a proper position to facilitate the successful completion of sealing.
