It can produce many wire nettings from the light one to the super-heavy one for the filtering and sludge dewatering in the envirornmental machinery. Developed by stm based on high-tech dobby system, control system, shedding system with 50 years production experience. Main constructions: 1. Framework: the main wallboard adopts iron box structure; the complete machine is combined with fissions. 2. Main drive: adopting bilateral motor two-sided coaxial drive; double pneumatic clutch; big brake torque of clutch. 3. Weft insertion mechanism: adopting picking stick pneumatic shuooting-in; automatic weft holding; pneumatic shuttle checking. 4. Shedding mechanism: adopting bilateral broad knife blade side-drawing dobby device, eight heald frames. 5. Beating-up mechanism: adopting multi-fissions crank four-linkage weft beating. Crankshaft has variable speed device drive with huge beating power. 6. Take-up mechanism: adopting electronic control three-roller positive take-up. 7. Let-off mechanism: adopting electronic control positive let-off (double warp beam, flange-separating warping). 8. Web-rolling mechanism: adopting external central web rolling driven by air cylinder. 9. Lubricating system: the main wallboard box is lubricated with oil bath and the others with automatic grease lubrication. 10. Control system: with plc computer control system, the complete machine can freely set up various parameters and automatically display faults. . Range of polyester monofilament: 0.5~1.2mm 2.
