Carding process line is replaced by a roll process to achieve clear, one of the new spinning process technology to produce continuous change carding process. Use as a carrier to transport raw materials airflow, integrated design process, the system more stable, achieve contact operation, all materials and dust mixed with air transportation are reduced intermediate storage semi links, with continuous feeding of cotton technology keep control, to ensure system stability . Continuous Feeding control technology from the high degree of control on cotton noil box. Continuous Feeding control technology can be divided into two phases: 1, fast, slow, stop mode; 2, (analog control) infinitely variable manner. On the use of a continuous feed hopper cotton Qingdao Hongda Textile Machinery FA172 early feeding hopper is the use of thin-film pressure switch for detecting a pressure drop hopper control, when the cotton tank pressure falls below a certain pressure setpoint, feed roller Slow for cotton; when the pressure exceeds the maximum setting, the feed roll stop for cotton. When the pressure switch control feed roller speed, feed roll speed and falling cotton tank pressure vary widely, and are not even change control result is cotton layer density difference changes, resulting in cotton layer thickness fluctuations, it is not easy to sort out and impurity uniform. Hopper in common is the use of continuous Feeding control technology, the hopper is controlled by the speed of the drive feed roller, the realization of gas-electric converter with analog pressure sensors, scaled tracking instead of film pressure switches, pressure sensors timely detection of fall cotton tank pressure, and timely adjust roller speed, velocity curve flat, stable layer of cotton, cotton-cotton tank height substantially to maintain a dynamic equilibrium. Continuous Feeding control technology utilized carding system continuously Feeding control technology in cotton box to ensure that the sliver weight uniformity as well as the stability of the yarn quality. In order to improve the continuity of the operation while carding the entire system, to improve operating efficiency, multi-warehouse blender to scutcher for cotton carding machine to card cotton are used for continuous Feeding control technology. Autoleveller in the application of traditional carding carding use side feed roller shaft drive, sliver weight unevenness is mainly determined by the weight per meter lap irregularity. When the lap 1m weight unevenness U% value at 1.0% to 1.5%, the sliver weight unevenness 5M U% generally only controlled 3.5% to 4.5% and mix thoroughly using a sliver of guarantees weight unevenness and evenness, reach sliver of the indicators of stability, using sophisticated self-modulation systems sliver length movie segment control adjustments 5m sliver weight unevenness U% monthly average of 1.5% The following, evenness CV% to 3.5% or less.
