Fixing Strapping Machine XQD19

XQD19 Strapping Machine Repair – Specializing in 100% mechanical pneumatic strapping machine repair

XQD19 strapping machine repair is a technical service for plastic strapping machines that operate entirely pneumatically. This is a 100% mechanical machine, does not use electricity, has no boards or electronic sensors.

The XQD19 machine performs 3 functions: tensioning – friction welding – wire cutting by mechanical mechanism combined with pneumatic pressure.

Working Principle of XQD19 Strapping Machine

The XQD19 uses compressed air (0.5 – 0.8 MPa) to:

• Belt tension piston operation
• Creating friction oscillations for welding PET/PP wires
• Activation of the mechanical cutting mechanism

The whole system is a gear – spring – piston – air valve mechanism. Therefore, when repairing the XQD19 strapping machine, it is necessary to understand the mechanical mechanism, not the electronics.

Common Mistakes When Repairing XQD19 Strapping Machine

1. The machine does not tighten the wire

• Worn drag rollers
• Sliding Drive Gears
• Weak gas piston
• Compressed air leaks

2. The machine does not weld the adhesive wire

• Wear Friction Welding Kit
• The surface of the welding knife is slippery
• Insufficient pressure due to weak piston

3. The machine does not cut the wire

• Worn cutting blades
• Jamming of the return spring mechanism
• Insufficient gas pressure

4. Pneumatic leak machine

• Piston seal failure
• Liquid gas hose connector
• Worn air valve

The XQD19 strapping machine repair service needs to check both the gas system and the internal drive mechanism.

Why does the XQD19 fail after use?

• Using the wrong size strap
• Unstable gas pressure
• Do not clean PET/PP plastic dust
• No routine maintenance
• Use compressed air with water to cause rust

Mechanical machines, if not properly maintained, will wear out faster than electronic machines.

XQD19 Strapping Machine Repair Service at T-PACK

✔ Inspection of the entire mechanical structure

Remove check gears, reels, springs, pistons.

✔ Compressed Air System Inspection

Pressure test, air leak test, seal replacement if necessary.

✔ Replace components in accordance with XQD19 standards

• Rulo Pulling Rope
• Tightening Gear
• Cutting Blade
• Gas Piston
• Air Valve

✔ 3-function complete test

Tightening – welding – cutting must reach the standard force before handover.
