How to Maintain a Used Marquip/Ward Paper System Production Line
It takes dedication to maintain a used Marquip/Ward production line, which usually consists of splicers, preheaters, a single facer, a double backer, rotary cutters, and stackers. Bearings, gears, and electrical components in used equipment frequently have accumulated wear. Restoring and maintaining "like new" performance is the aim.
1. Create a Systematic and Baseline Assessment
Do a complete "production worthiness" review before putting a secondhand line into full service. Examine every safety system first because older equipment frequently has worn switches. Next, examine the electrical systems (motors, drives, sensors), pneumatics (air cylinders, hoses), mechanical parts (shafts, gears, bearings), and lubrication systems. Prioritize repairs by recording each flaw in a thorough report.
2. Operator Checks Every Day
Check that all emergency stops and safety guards are operating during each shift. Verify the oil levels in gearboxes and lubricate all chains and bearings in accordance with the grease points specified in the handbook. Check for air or oil leaks and listen for odd noises, such as slipping belts or grinding bearings. To stop corrosion, remove starch from stationary surfaces and adhesive residue from glue rolls.
3. Plan for Preventive Maintenance
Every week: Check single facer corrugating rolls for profile damage, tighten loose chain drives, and examine slitter and scorer wheels for wear.
Vacuum pumps and gearboxes should have their oil changed once a month. To guarantee uniform board curing, calibrate the heat sensors on preheaters and the double backer.
Check all areas for alignment on a quarterly or annual basis. Replace the rotary shear or cut-off knife's worn-out blades. Replace pneumatic regulators and filters.
4. Components and Instruction
For essential components (corrugating rolls, cut-off knives), always use OEM or comparable high-wear parts. Make use of the operator and maintenance training programs that are offered to make sure your staff is familiar with the particular peculiarities of your used line.
Keep a thorough log of everything you do. The only way to optimize the return on a used Marquip/Ward investment is by routine, methodical maintenance.
