MARO-I automatic winder linked with spinning frame, is a new generation automatic winder developed by Qingdao Hongda Textile Machinery Co, Ltd. The winding speed can reach up to 2200 m/min. Adopting advanced control technology, the winding techniques and yarn track are designed in a brand-new way, thus its mechanical structure is simplified, air loop is better controlled and the electric intelligence is improved. The machine adopts global monitoring to obtain yarn with higher quality and more profit to improve the productivity largely.
High quality
Automatic bobbin feeding from spinning frame to auto-winder improves yarn cleanness and avoids yarn contact damage.
Enhancing automatic level, saving manpower
To transport yarn package and feed bobbin automatically so as to save labor and connect the two labor-intensive procedures directly not only to realize automation and continuous production but also to improve quality and enhance productivity.
High efficiency
To solve the friction between package of spinning frame and speed so as to enhance the spindle speed of spinning frame and increase productivity
High efficient and high quality piecing unit
· Fiber sensor detects current piecing condition
· Upper and lower air door control to enhance piecing rate and efficiently control air consumption efficiently.
· Vertical liner suction cylinder moves up and down to enhance motion precision.
· Reasonable suction clip and vertex blowing system can greatly enhance piecing rate.
Completely automatic yarn supply
· Bobbin supply from spinning frame to auto-winder is completely automatic, free of manual feed. Behind single spindle it is designed with spare bobbin convey channel.
· Bobbin conveyor increase logic judgment to make following actions such as full bobbin, empty bobbin, piecing, re-piecing, waste yarn treatment, stop, pass in CBF not interfered with each other.
· Bobbin change is automatically detected and feed.
· Empty bobbin is automatically transported back to spinning frame by loop belt.
· Bobbin is transported by support disc that eliminate bobbin yarn surface damage and reduce pilling increment.
