How to quickly diagnose and repair common faults (such as compound needle closing error, data recovery failure, freeze, etc.) of needle-plate computerized flat knitting machines?

During the use of needle plate computer flat knitting machine, various common faults may be encountered, such as compound needle closing error, data recovery failure, freezing, etc. The following are quick diagnosis and repair methods for these common faults, designed to help operators quickly restore the normal operation of the machine.

1. Compound needle closing error

Diagnosis:
First, check whether the compound needle closing sensor is working properly. The sensor may cause signal transmission errors due to dust, dirt or damage.
Second, observe whether the compound needle motor rotates normally. Motor damage or jamming may also cause compound needle closing errors.
Repair:
Clean the dust and dirt around the compound needle closing sensor to ensure that the sensor can work properly.
If the sensor is damaged, a new sensor needs to be replaced.
Check the power connection and mechanical transmission part of the compound needle motor to ensure that the motor can rotate normally. If the motor is damaged, a new motor needs to be replaced.
2. Data recovery failure

Diagnosis:
Check whether the data recovery failure is caused by illegal shutdown of the computer or not shutting down the computer for long enough.
Check whether the charging capacitor is aging or damaged, which may cause the data to not be restored normally.
Repair:
If the data recovery fails because the computer is shut down illegally, you can try to restart the machine and make sure that the correct shutdown process is followed when the computer is shut down.
If the data recovery fails because the computer is not shut down long enough, you can wait for enough time to try to recover the data again.
If the charging capacitor is aged or damaged, you need to replace it with a new charging capacitor.
3. Crash

Diagnosis:
Check whether the power supply of the computer flat knitting machine is normal. Power failure may cause the machine to crash.
Check whether there are external interference factors, such as electromagnetic interference, voltage instability, etc.
Check whether there are overheating, overload and other problems inside the machine.
Repair:
Make sure the power plug is plugged in tightly, the power cord is not damaged, and the power switch is on.
If there are external interference factors, try to move the machine to another location or take other anti-interference measures.
Check whether the cooling system inside the machine is working properly, such as whether the fan is rotating, whether the heat sink is blocked, etc. If there is a problem, clean the cooling system or replace the cooling device in time.
If the above methods cannot solve the problem, you can try to restart the machine or contact a professional maintenance personnel for inspection and repair.
When dealing with these common faults, operators need to have certain professional knowledge and skills, and must follow the correct maintenance process and safe operating procedures. In addition, regular maintenance and care is also one of the important measures to reduce the occurrence of faults.
