TDP-501 Leno Fabric&Onion Bag Weaving Machine
Active Warp Let-Off System
Intelligent sensing of warp beam excess and automatic adjustment of warp delivery speed can avoid uneven fabric density caused by manual intervention. It is especially suitable for stable production of high-weight PP/PE woven bags.
Electronic Weft Storage
Real-time dynamic compensation for yarn tension fluctuations, weft density accuracy error ≤ 0.5%, reducing defects such as yarn breakage and loose edges, the uniformity of finished products reaches the industry A+ standard, and raw material waste is reduced by 15%.
Heavy-Duty Box-Type Structure
Thickened steel plate and reinforced frame improve vibration resistance by 40%, ensuring no abnormal vibration at high-speed operation (600-800rpm), reducing the failure rate by 25%, and making it suitable for continuous production.
Material Compatibility
It can be adapted to recycled PP/PE granule raw materials. Under the premise of ensuring strength, the raw material cost can be reduced by another 10%-15%, responding to environmental protection policies and customers' sustainable procurement needs.
One-Click Parameter Preset
Built-in multiple weaving patterns (such as onion bag/citrus net, etc.), shortening the switching time for new orders and reducing the dependence on skilled workers.
Self-Diagnosis System
Real-time alarms are issued when critical components (motors, sensors) are abnormal, the accuracy of fault location is improved, the efficiency of maintenance response is enhanced, and losses from unplanned downtime are avoided.
