5. Working Principle
Warp unwinding: Warp wires are released from warp beam and arranged neatly through heald frames and reed.
Shed forming: Crank-link mechanism drives heald frames to move up and down alternately to form a shed between upper and lower warp wires.
Weft insertion: The shuttle carrying weft wire slides through the shed to complete one weft penetration.
Beating-up: The reed moves forward to compact the new weft and fix standard mesh holes.
Automatic winding: The finished mesh is rolled evenly on the take-up roller under constant traction. The above cycle repeats continuously to form mesh rolls.
6. Production Process
Raw material inspection: Check wire diameter, surface coating and tensile strength, eliminate defective metal wires.
Warp beam winding: Wind qualified warp wire onto warp beam neatly without overlapping or tangling.
Threading: Pass each warp wire through heald eyes and reed gaps according to required mesh size.
Shuttle bobbin loading: Wind weft wire on small bobbins and install them inside the shuttle.
Parameter setting: Adjust weaving speed, warp tension and mesh width on the control panel.
Trial weaving: Produce a small piece of test mesh to check aperture uniformity and adjust parameters if defects appear.
Mass production: Start automatic continuous weaving, the machine winds finished mesh into rolls automatically.
Post-processing: Cut mesh rolls to required length, conduct surface inspection, then pack and store finished products.
7. Operation Methods
Before Startup
Clean dust and broken wire residues on the machine body. Check lubricating oil of bearings, crankshaft and gears, add grease if insufficient.
Inspect all circuits, emergency stop button and broken-wire sensor to ensure normal function.
Install warp beam and shuttle bobbins correctly, adjust warp tension to standard value.
During Operation
Power on the control cabinet and set production parameters on the operation panel.
Jog the machine at low speed to test mechanical movement; stop and troubleshoot if jamming or abnormal noise occurs.
Switch to automatic mode for formal weaving, inspect machine status every 30 minutes.
Pause the machine to replace weft bobbins when the weft wire inside shuttle runs out.
After Shutdown
Stop automatic operation after finishing one complete mesh roll and cut the mesh neatly.
Cut off the main power supply, clean waste wires inside the loom and lubricate moving parts for next shift.
8. Precautions
Safety Operation Notes
Operators shall wear tight work clothes; long hair must be covered with hairnets to avoid being caught by moving components.
Do not put hands into shuttle running area, heald frames or beating reed when the machine is powered on.
Press emergency stop button immediately once jamming, strange noise or wire winding failure occurs; maintenance can only be done after full stop.
Only professional maintenance staff can open the electric control cabinet; random circuit modification is forbidden.
Daily Maintenance Notes
Lubricate all rotating bearings every day, fully check transmission parts every week.
Clean photoelectric sensors regularly to avoid auto-stop failure caused by dust accumulation.
Do not feed wires exceeding the machine’s rated diameter range to prevent overload damage.
Keep the workshop dry to avoid short circuit of electrical components caused by moisture.
Carry out comprehensive overhaul every 3–6 months and replace severely worn shuttles, reeds and other spare parts in time.
