Open End Spinning Machine
It is suitable for yarn count 3s to 40s , and raw material
can be both raw cotton and waste cotton.
OE40D Open end spinning machine
It fully collects and analyzes data, optimizes spinner for spinning-yarn quality. Patent system processes various materials, aids customers, cuts labor. Ceramic-coated opening reduces fiber wear, extends life.
The standard pneumatic lifter has 0.1 sec breaking response and high reliability. The unique joint system makes the roller guide yarn before the winding roller during jointing to prevent bobbin impact. Exclusive math jointing and stepping roller feeding precisely control volume and time for joint strength and shape.
Intelligent start: semi-auto mode replaces labor, enables auto doffing without break ends, cuts labor intensity. High efficiency: standard doffing in 20s from fixed position. Intelligent function: supports auto and manual doffing modes.
The device greatly reduces the labor intensity of the maintenance work, ensures the grid distance stability, and improves product consistency.
Program of machine can be upgraded online, online monitoring and early warning of the main transmission components, and user can know the actual operation of equipment in real time around the world.
The digital control can reduce the complicated mecharnical adjustment work. The user can directly adjust the tension ccoefficient in the monitor of headstock, and the adjustment precision can reach 0.001, which ensures the stable forming for winding package.
The system will reduce the labor intensity of the operator, and also provide a more stable negative pressure environment for the machine, which makes spinning production more stable and improves the consistency of the yarn quality.
The system can reduce the accumulation of flying and dust in the inner cavity of headstock and tail box, reduce the labor intensity of the maintenance worker, improve the heat cooling condition of the electrical components, thereby increasing the stability of the runniring of the machine and reducing the energy consumption.
