The automatic waste paper baler
is mainly used in waste recycling companies. If the baler often fails, it will inevitably affect the normal packaging efficiency. Therefore, in our daily use, it is very necessary to master the common troubleshooting methods. The machine will take you to understand it together.
1. Fault phenomenon: the device makes an abnormal sound
The cause of the failure: the oil is too cold, the air filter is clogged, the oil viscosity is too high or the oil quality is deteriorated, the oil pump is loosely fixed, causing the concentricity difference to be too large, and the oil suction filter is blocked.
Remedy: oil heating, cleaning the air filter, replacing or filtering the hydraulic oil, tightening the fixed winch of the oil pump, cleaning the suction filter.
2. Trouble phenomenon: oil temperature rises too fast
The cause of the failure: the oil pump components are worn and cause serious internal leakage, and the surrounding environment temperature is too high.
Remedy: replace the oil pump, change the environmental conditions (use cooling).
3. Trouble phenomenon: hydraulic pressure, unstable pressure gauge indication
The cause of the failure: there is air in the system, the oil suction vacuum is too large, the pressure gauge seat is in a state of vibration, and the oil temperature is too high.
Elimination method: Exhaust air at the highest point of the system or at the oil suction pipe, reduce the vacuum degree to less than 16mm, eliminate the cause of surface vibration, and use cooling to reduce the oil temperature.
4. Trouble phenomenon: the main cylinder does not move
The cause of the failure: the oil pump is reversed and there is no oil pressure, the orifice of the overflow valve is blocked, the inlet and outlet are opened, the oil tank inlet stop valve is not opened, the spool of the electromagnetic reversing valve is blocked and the solenoid of the electromagnetic reversing valve is open. .
Remedy: change the direction, clean and install correctly, reopen the shut-off valve, find the circuit, the spool of the electromagnetic directional valve is blocked and does not work, and clean the electromagnetic directional valve.
5. Failure phenomenon: thread threading is not in place
The cause of the failure: The iron wire cannot be worn in manual/automatic mode, there are torn paper pieces in the pressure head slot, the iron wire is not tightened, and the pressure is low.
Remedy: Check whether there is iron wire/iron wire on the wheel, manually retract the pressure head to the proper position, take out the shredded paper after the pressure head stops, tighten the iron wire, and adjust the overflow valve.
The cause of the failure: the overflow valve is blocked, the oil pump is damaged, and the main motor is reversed.
Remedy: clean or replace the overflow valve, replace the oil pump, and change the electricity.
7. Trouble phenomenon: no action when threading
The cause of the failure: the pressure head is not in the front limit, check the front limit proximity switch and the overflow valve of the threading machine.
Remedy: Adjust the pressure head to the front limit. If there are iron substances near the proximity switch, remove or replace the switch and clean the overflow valve (note: each bolt is placed in the original position during disassembly and installation).
8. Failure phenomenon: the indenter does not move
The cause of the failure: the rear limit of the threading machine, the material is not full, the photoelectric switch cannot receive the signal, the indenter and the threading machine must be at the rear limit at the same time, the knife board and the thread must be at the rear limit, and the motor is in the original position , The reversing valve is jammed.
Elimination method: the threading machine should be stopped at the rear limit, the material should be filled up, the indenter and threading machine should be adjusted to the rear limit, the knife plate and the thread cutting should be adjusted to the rear limit, the motor should be adjusted to the original position, and cleaned Reversing valve.
9. Trouble phenomenon: the threaded rod does not go back
Cause of failure: Check the proximity switch of the waste paper baler
, the overflow valve is blocked, the pressure head is released, and it is out of the front limit.
Remedy: Check the proximity switch, clean the overflow valve and pressure relief valve jam, and clean the pressure relief valve.
