Common failure of carton compression testing machine

Common failure of carton compression testing machine
     Carton compression testing machine to use for some time, prone to large and small failures, affecting the daily operation. The details are as follows:
First, the carton compression testing machine mechanical system of general failure
         1, the lower transmission chain wear elongation, affecting the host to work
               Because after long-term use chain or chain hole wear chain chain perimeter increases, should adjust the chain tension wheel position.
          2, between the upper and lower plate surface parallelism tolerance, affect the test accuracy
                 A, the chain elongation of the two drive screw relative angular displacement should be adjusted to adjust the chain tension wheel       position.
                 B, the upper four upper tension plate tension stress-strain relationship changes, should adjust the spring compression length.
Second, the carton compression testing machine control system of general failure
              1, no display, key failure
                  The fuse may be burned, the power switch is damaged, the power cord is not well connected or loose, replace the fuse, replace the power switch, check the repair power cord.
              2, after power or the use of chaos display, the button does not work
                  System "crash", should press the "reset" button or turn off the power to reboot.
              3, press the "print" button the printer does not move
                A, print head connection loss or poor contact, should check the print line.
                B, the print head is damaged, you should replace the print head.
             4, the display no display or chaos display, but the test machine other functions are normal
                 A, monitor connection loss or poor contact, should check the line.
                 B, the display is damaged, should replace the monitor.
             5, the display is normal, part of the button does not work
                 If the button is damaged, replace the button.
             6, the display is normal, the motor working state out of control
                 Motor control circuit failure, should check the circuit, identify the fault and take appropriate measures (by professional staff)
