RFDF12 Autoleveller Drawing Frame

Completely independent drawing system

The  sliver output speed of the machine is controlled through frequency conversion, and various process parameters are set directly and quickly on the man-machine interface. According to different raw materials and quality requirements, the two deliveries can be adjusted to the appropriate speed, so as to match the production demand, and the two deliveries are completely independent; according to the process requirements, different roller spacing, different draw ratio and different running speed can be set for the left and right deliveries, so that the production allocation is more flexible, and the convenience for modicum and varied quick spinning frame modification is realized.

The rubber covered roll can be raised with the cradle

The pressure of drawing cradle is adjustable and the spring pressure is stable; the rubber covered roll can be raised with the cradle, so that it is convenient for the spinner to conduct operation, the labor intensity is reduced and the working efficiency is improved.

High precision drawing roller

The drawing roller which is first-class in China is adopted, the drawing roller has enough bending stiffness and torsional stiffness. The teeth of surface groove are made according to the high standards, high smoothness is realized. It is featured wear-resistant surface and tough center, spinning quality is ensured, and unevenness of yarn sliver is avoided.

The latest generation of autoleveller system

The whole machine adopts two sets of independent latest autoleveller systems from Uster Company, the system has the functions of autoleveller and online quality monitoring and control. According to the fluctuation of fed slivers, the quality of output slivers is timely controlled online. And the alarm limit can be preset, so as to prevent defective slivers from entering the next working procedure and ensure the yarn quality.

High-precision detection device

The embossing roller detection mode is adopted for detection of the sliver fed, the detection mode adopts pneumatic pressurization and intelligent control of pressure relief. Adopt strict processing technology to realize the accuracy and strength of embossing roller device; the standard high-precision and high-response displacement sensor is equipped with, it can detect the fluctuation of fed sliver, effectively improve the dynamic autoleveller effect, and the control range is ±25%.

High-precision coilers with various specifications

The domestic first-class high-specification coiler is adopted, which has the characteristics of light weight, good molding and no tops, etc. According to the process requirements, the coilers with various specifications can be provided.  

Automatic sliver can switchover

The whole machine adopts two completely independent automatic sliver can switchover. The automatic sliver can switchover adopts pneumatic control mode, it is in the form of pushing sliver can out and in from the front, the sliver can change efficiency is high, the space is saved, and the maintenance is convenient. And the quantity of spare empty sliver cans can be increased according to the needs of users.

Actively feeding guide bar frame mechanism

Adopt the actively feeding guide bar frame made of high-specification aluminum profile, to ensure that the frame does not deform, the operation is smooth, and the sliver will have no accidental drawing. At the same time, at several positions, the photoelectric operation buttons are set for digital detection of broken slivers, so as to improve the quality of fed slivers, reduce labor intensity and improve work efficiency.
