When the fully automatic feeding machine malfunctions, the repair steps should be determined based on the specific symptoms of the malfunction. Here are some common faults and corresponding repair methods:

　　1. Poor or no feeding:

　　Check if the power supply of the feeding machine is normal, including power switches, fuses, circuit wiring, etc.

　　Check the smoothness of the feeding valve and whether there is any material blockage.

　　For vacuum feeders, check if the compressed air supply pressure is sufficient (usually 0.4-0.6MPa), as insufficient pressure can affect the blowback force and suction speed.

　　Check whether the transmission components of the feeding machine are worn, such as the tightness of the belt and whether the motor is working properly.

　　2. Slow feeding speed:

　　Check if the motor speed meets the requirements and if the motor power supply voltage is stable.

　　Check if the feeding valve is fully open and if there are any blockages that affect the flow of materials.

　　Clean up the accumulated material inside the feeder and in the pipeline to ensure smooth material flow.

　　3. Machine abnormal noise or excessive vibration:

　　Check if the transmission components are severely worn, such as bearings, gears, etc., and replace them if necessary.

　　Check if the base of the feeding machine is stable, and adjust it to a horizontal state if it is uneven.

　　Check if the fastening screws are loose and ensure that all components are securely connected.

　　4. Electrical malfunction:

　　Check for damage to electrical components such as controllers, button switches, contactors, relays, etc., and replace them if necessary.

　　Check if the circuit wiring is correct and if there are any short circuits or open circuits.

　　When repairing the electrical part, be sure to cut off the power supply to ensure safety.

　　5. Leakage problem:

　　Check whether the pipeline connection of the vacuum feeder is firm to prevent air leakage from affecting the vacuum degree.

　　Check if the bucket ring is installed properly and replace it promptly if it is damaged.

　　6. Other faults:

　　Perform troubleshooting based on the fault indicator light or fault code.

　　Refer to the equipment manual or contact the manufacturer's technical support for assistance.

　　When repairing a fully automatic feeding machine, safety operating procedures should be followed to ensure the safety of personnel and equipment. At the same time, regular maintenance and upkeep of the equipment can effectively prevent malfunctions and extend its service life.
