Preventive Maintenance for Industrial Sewing Machines

There is a type of maintenance called "preventive maintenance", which refers to regular, routine maintenance to help keep equipment running normally, Preventing unnecessary losses from any unplanned downtime and unexpected equipment failures.

It requires careful planning and scheduling of equipment repairs before actual problems arise, and accurate recording of past inspection and repair reports. In practice, preventive maintenance programs can include cleaning, lubrication, oil changes, adjustments, repairs, inspections, and replacement of parts, as well as regularly scheduled partial or total overhauls.

There are 10 parts that need to implement for preventive maintenance on the sewing machine, namely the machine needle, the hook, the bobbin (the looper of the overlock sewing machine and the interlock sewing machine), the thread stand, the thread cutting mechanism (the cloth cutter of the overlock sewing machine), Sewing oil, oil pump (lubricating oil), thread tensioner, feed dog, presser foot, needle plate, control box, air pressure, electronic media (FD, etc.) The increase or decrease depends on the situation of the machine.

In daily preventive maintenance, in addition to the above 10 points that need special maintenance, replacement of parts and repairs are also places that require special attention.

First of all, when performing maintenance, inspection, and repair work, be sure to turn off the power and confirm that the sewing machine is completely stopped before operating.

Secondly, all parts used in repairs must be provided or approved by the original factory, and replacement parts must be operated by professionally trained personnel. When replacing parts, use appropriate tools and replace them according to the instructions in the manual.

Finally, when repairing the electric control board, it is necessary to confirm whether the solder has bad contact with other components, whether the insulating material on the circuit board has been restored to its original state, and whether the terminals, plugs, and cables are in poor contact, damaged, dropped, and loose.

Routine maintenance can not only prevent the occurrence of sewing machine failure but also ensure the quality of sewing. Cleaning is the most trivial and easily overlooked place in daily maintenance, but if the five important parts of the machine needle, wiper needle bar, rotary hook, looper, thread trimmer, cloth cutter, and oil pan are cleaned in place, the sewing stitches will be smoother and the sewing effect will be better.
