When an OCC (or similar) paper baler fails to move forward or backward, several mechanical, hydraulic, or electrical issues could be the cause. Below are common reasons and troubleshooting steps:Hydraulic System Malfunction:Low Hydraulic Oil: Insufficient oil levels can prevent the ram from moving. Check the oil reservoir and refill if needed.Oil Leaks: Damaged hoses, seals, or cylinders may cause pressure loss.Inspect for leaks and replace faulty components.Clogged Filters or Valves: Contaminated oil or blocked filters can restrict hydraulic flow. Clean or replace filters and flush the system if necessary.Electrical or Control System Failure:Power Supply Issues: Ensure the machine is properly connected and receiving power. Check circuit breakers, fuses, and wiring.Faulty Sensors or PLC:Malfunctioning limit switches, proximity sensors, or PLC errors can halt movement. Reset the system or replace defective sensors.Control Panel Errors: Error codes on the display may indicate electrical faults—consult the manual for diagnostics.
Mechanical Obstructions:Jammed Material: Overpacked or improperly loaded paper can block the ram. Clear the chamber and avoid overloading.Misaligned or Worn Guides: If the ram is stuck, check for bent rails, worn rollers, or debris obstructing movement. Lubricate and realign if needed.Pressure or Pump Problems:Faulty Hydraulic Pump: A failing pump won’t generate enough pressure to move the ram. Test pump performance and replace if necessary.Pressure Relief Valve Issues: Incorrect settings or a stuck valve can limit hydraulic pressure. Adjust or replace the valve as required.Safety Interlocks Engaged:Door or Gate Sensors: If safety doors aren’t fully closed, the baler may not operate. Ensure all interlocks are engaged.
The NKW160Q OCC Paper Baling Machine is a high-performance, fully automatic horizontal baler specifically engineered for processing OCC paper, newspapers, cardboard, and soft film materials.
This versatile machine transforms bulky paper waste into compact, high-density bales—optimizing storage, reducing transportation costs, and streamlining recycling operations.Utilizing an advanced hydraulic transmission system with dual-cylinder operation, the NKW160Q delivers a powerful 150T main cylinder force at a maximum system working pressure of 30.5 MPa.Its sophisticated PLC control system, complete with photoelectric sensors and automatic error detection, ensures precise feeding, compression, and bale ejection.
The adjustable bale parameters allow operators to customize bale size (approximately 1100 × 1100 × up to 1600 mm) and achieve a material density of 600–700 kg/m³.An integrated NK-III chain conveyor further enhances continuous operation, while features like automatic strapping and a disposable bale ejection system make the process highly efficient and safe.This machine is designed to meet the rigorous demands of high-volume recycling centers and packaging waste management facilities.
