Paper running status, ink rollers of various color groups work with inkjet printing, and roller clutch pressure. The control of various components such as the take-up machine, the BPLC is connected to the man-machine interface of the sample inspection table, mainly to complete fishing adjustment, printing cylinder pressure adjustment, and ink motor speed adjustment. A synchronous motor is used to drive a multi-turn potentiometer to take a feedback voltage signal to complete fishing. Precise positioning control. The transmission of the ink roller is completed by each independent frequency conversion motor, according to the operation instruction DTP! BPLC performs calculations, and the calculation results are sent to the DA module. The digital signals are converted into analog signals and then sent to the response inverter for speed adjustment. At the same time, BPLC and APLC complete the speed tracking of the ink motor and the host through RS485 communication to achieve accurate stepless speed regulation. CPLC controls the host to run. Appraisal failure case. Beiren N300 offset press has a phenomenon that the paper suction roller does not work, which is excluded by analysis. The speed of the paper suction roller is set through the touch screen. Its speed should be synchronized with the host. Turn on the control switch and find that the suction roller does not rotate. Use a multimeter to detect The motor input voltage shows only a few volts of input voltage labels. Obviously these volts are induced. Analyze the overall control program of the control circuit and set the control of the CPLC1CPLC1F1 inverter motor. First check that the set control is normal and the input power voltage of the inverter is normal. The inverter does not display any fault information, then. Set the control, the motor inverter can basically eliminate the fault range, the inspection focus is on CPLC1 and CPLC1F1, use a multimeter to measure the excessive packaging of the two output terminals of CPLC1F1CH2, these two ends are analog output after conversion by the DA module, the normal situation should be Only about DC15V, the frequency converter can work, and now the measured value is only about 07V. Obviously the problem is in CPLC1 and CPLC1F1, and the two are connected by a cable to the gravure. Check the cable and found no problems! Because these two parts are component-intensive parts, they cannot be detected during work, and can only be judged by the alternative method. It was finally determined that the digital signal transmitted from CPLC1 to CPLC1F1 caused an error. After replacing CPLC1, the fault was eliminated, and Kodak pressed the bumps when brushing a batch of 128gm2 coated paper color pages. Whether it is a monochrome offset press or a four-color offset press! From the start of the gripper to the end of the printing, the paper has to be handed over many times, especially the four-color machine combination printing, the vertical type has to pass 9 times, and the horizontal type has to pass 5 times. The gripping force adjustment of the gripper plays a vital role in the overprinting of the printed matter. Improper adjustment may cause the overprinting of the printed matter, ghosting angles, wrinkling of the paper, ripping of the gripping mouth and other faults.
