What are the solutions to common faults of computer flat knitting machines

Hardware failure and solution
Main control board failure
Phenomenon: The device cannot start or runs abnormally.
Solution: First, the main control board needs to be visually inspected to confirm whether there are obvious signs of damage such as burning or deformation. Next, check the connection wires between the main control board and each component to ensure that they are not loose or damaged. If the main control board is found to be damaged, it should be replaced in time to restore the normal function of the equipment.
Motor board failure
Phenomenon: The motor cannot work properly or runs unstably.
Solution: Check all kinds of components on the motor board, including resistors and capacitors, for damage. Use a multimeter to measure the input and output voltages of the motor board to ensure that they are within the normal range. If the motor board is damaged, it needs to be replaced to ensure the stable operation of the motor.
Head board failure
Phenomenon: The head cannot work properly, which is manifested as abnormal signal transmission or unsmooth movement.
Solution: Check whether the connection wires on the head board are loose or damaged to ensure smooth communication between the head board and the main control board. If the head board is damaged, it should be replaced in time to ensure the normal operation of the equipment.
CPU board failure
Phenomenon: The device starts slowly, runs stuck or freezes.
Solution: Check whether the heat sink on the CPU board is working properly and ensure that the temperature of the CPU remains within a reasonable range. If the CPU board is damaged, it needs to be replaced and the system parameters need to be reinitialized to restore the efficient operation of the device.

Software failure and solution
Program error
Phenomenon: Missed needles, wrong needles and other problems occur during the knitting process.
Solution: Check and update the software system of the device to ensure the compatibility of the program version with the hardware. If there is an error in the program, it needs to be repaired or reinstalled to eliminate the fault.
Improper system configuration
Phenomenon: The device runs unstably, and there are frequent freezes or restarts.
Solution: Check and adjust the system configuration of the device to ensure that the parameter settings meet the requirements. If the configuration is improper, it should be adjusted according to the device manual or the advice of the technician to improve the stability of the device.
Virus attack
Phenomenon: The device runs significantly slower, and there are problems such as file damage or loss.
Solution: Install and regularly update antivirus software to conduct a comprehensive scan and cleanup of the device. At the same time, strengthen the security management of the equipment and take preventive measures to avoid the virus from invading again.

Mechanical failure and solution
Transmission device failure
Phenomenon: abnormal noise or vibration occurs when the equipment is running.
Solution: Check the gears, bearings and other key components of the transmission device to confirm whether there is severe wear. If damaged parts are found, they should be replaced in time. At the same time, lubricate and maintain the transmission device to ensure its smooth operation.
Needle bed failure
Phenomenon: The knitting effect is not ideal, which is manifested as too large needle holes or uneven stitches.
Solution: Check the needle plate, needle hook and other components of the needle bed to confirm whether there is damage or deformation. If necessary, replace the damaged parts in time. At the same time, adjust the needle bed's needle length and needle depth to ensure that the knitting effect meets the expected standards.
Yarn mouth failure
Phenomenon: The yarn cannot be transported normally, or the yarn mouth is blocked.
Solution: Check the internal structure of the yarn mouth to confirm whether it is damaged or blocked. If a blockage is found, the damaged parts should be cleaned or replaced in time. At the same time, adjust the position and angle of the yarn mouth to ensure smooth yarn delivery and smooth knitting process.
