The carton compression testing machine is a testing equipment often used by paper packaging manufacturers. After a certain period of use, manufacturers will have large and small problems. For your convenience, it is summarized as follows. I believe it can help you.
1. Mechanical system failure of carton compression testing machine
1. The lower transmission chain is worn and elongated, which affects the normal operation of the main engine.
It is because the chain shaft or the chain plate holes are worn after long-term use, which increases the circumference of the chain, and the position of the chain tensioner should be adjusted.
2. The parallelism between the upper and lower platen surfaces is out of tolerance, which affects the test accuracy.
A. The elongation of the chain causes relative angular displacement of the two drive screws, and the position of the chain tensioner should be adjusted.
B. The stress-strain relationship of the four tension springs on the upper platen changes, and the compressed length of the springs should be adjusted.
2. Failure of the measurement and control system of the carton compression testing machine
1. No display, key failure
It may be that the fuse is burned out, the power switch is damaged, or the power cord is in poor contact or loose. You should replace the fuse, replace the power switch, and check and repair the power cord.
2. After power on or during use, the display is disorderly, and the buttons do not work
If the system "crashes", you should press the "Reset" button or turn off the power and restart it.
3. Press the "Print" button, the printer does not work
A. The connection line of the print head is disconnected or poorly connected, and the printing line should be checked.
B. The print head is damaged, and the print head should be replaced.
4. There is no display or random display on the display, but other functions of the testing machine are normal
A. The display connection is disconnected or the connection is poor, the circuit should be checked.
B. If the display is damaged, the display should be replaced.
4. The display is normal, but some buttons do not work
The key is damaged and should be replaced.
5. The display is normal, but the working state of the motor is out of control
If the motor control circuit is faulty, check the circuit, find out the fault and take corresponding measures (handled by professionals)
