The maintenance of automatic face mask machine is very important. It can not only delay the speed of reducing the accuracy of the machine, but also reduce the probability of equipment maintenance. Generally, we divide the maintenance of automatic face mask machine into several aspects: appearance, transmission system, electrical system, ultrasonic system and pneumatic system. (the maintenance of the equipment must be carried out after shutdown and power failure)
Appearance: masks are used by us to wear on the face, some even need to be used in the operating room, so the production of masks must require that the mask machine must be clean and tidy. At the end of each day, personnel shall be arranged to clean the working surface of the equipment and the plate containing the mask after the power is cut off. It shall be noted that water and oil shall not be used. Alcohol and other non-toxic and volatile cleaning liquid can be used.
Transmission system: the transmission system includes motor, gear, reducer, chain wheel, chain, conveyor belt and other components. We need to check whether there is dust on the external surface of the motor that affects heat dissipation, whether there is oil on the gear and chain wheel, and whether there is any attachment. Whether the chain tightness is appropriate, whether there are foreign matters, whether the connecting screws between the transmission parts are loose, etc. Is there enough lubricating oil for the reducer? Generally, the lubricating oil needs to be changed once in 1000-1500 hours.
Electrical system: check whether the circuit connector of the equipment is loose, and whether the main power line and branch signal line are worn? Ageing? Loose electrical parts? Whether the electric box is clean and dry, whether the exhaust fan works normally, etc.
Ultrasonic system: (composed of ultrasonic box, vibrator, welding head and connecting wire) check whether the ultrasonic system is clean, especially the ultrasonic box, vibrator (transducer) and welding head (expansion ratio) must be dry and clean without water, and the connecting wire must be solid. Check the wear degree of ultrasonic welding head from time to time. Observe the change range of voltmeter and ammeter pointer on the ultrasonic box.
Air supply system: (composed of air source filtration system, air pipe and air cylinder) is there water in the air filter cup? Discharge water and discharge water to the air compressor by the way (discharge water to the air compressor: discharge water to the air compressor every day in the area with high humidity). Check the air pipe for air leakage? Is the cylinder leaking? Whether the position and operation of air cylinder magnetic protection sensor are normal.
In addition: the equipment shall not contact with corrosive liquids and objects, such as sweat, which is very easy to cause rust of equipment parts. The equipment is not used for a long time, such as vacation. Apply anti rust oil to the transmission system and easily rusty parts of the mask machine.
