4. Main units composition and characteristic.

1,  Into-cloth frame unit
This unit is comprised of frame, tight cloth frame, cloth roller, power rubber roller, tension frame, centring device, and two roller brush box. Frame use C type steel structure, inside have high strength stay pipe, this structure is compact and sturdy. Front column equipped hanging two rollers brush box with two ?150 screw natural bristles brushing rollers inside and use flat belt collective drag by 2.2kw motor. The noise is small and transmission is steady. On the bottom equipped vertical-vacuuming pipe, with 4KM textile dust exhausting fan. Low noise and good deducting results. The material of wind plate is aluminum alloy which can avoid frictional sparking effectively. The brushed fuzz and impurities can be discharged to outdoor by dust exhausting fan through the vacuuming pipe. This not only reduces environmental pollution, but use for ensuring safety in production.
2,  Singeing unit 
The singeing unit is comprised of separator roller, singeing burner, ?570 cold water tank, power roller, tension frame, combustion blower, smoke exhaust fan. Singeing burner is made of MJS-Burner which is the patent burner designed by our factory (Patent Number: 99222266.4). This burner is made of special iron casting, and there are two water cooling channels, to avoid burner deformation caused by high temperature. The burner inlet pipe is simple and easy to operate, to mix air and gas more sufficiently, and burn more completely. To adapt to the different burning technology of users, they can adjust the distance of burner & fabric, and the angle of burner &cool roller according to different of cloth and technology. There are hand steering gear, autosteerer and blackout self-return device, to avoid burning out fabric because of power outage. There are smoking pipe and smoke extraction fan on the top of this unit, it can discharge the flue gas outside, to be safety producing and protect the environment.
 
3.  Fire extinction, cooling unit
This unit is composed of a steam fire box, two ?570 cold water rollers, a transmission roller and a tension shelf. The box and the steam pipe are made of stainless steel, and there are 3 power wire rolls inside, which can effectively prevent the knitted cloth from curling. The reasonable proportion distribution of the height and the width can reduce the steam from escaping and consumption effectively. The cloth inlet part of the box is equipped with two movable glass doors, which can help us to put the cloth in and observe the effect of fire extinguishing. This cold water roller, roller wire and power transmission roller are powered with the same reducer.
4  Down-cloth frame unit
The down-cloth frame use speed reducer drive separately, there are swing arms at both sides of ?230 out-cloth roller, and there are 2 rough rubber off-cloth rolls on the swing arms. It can get different swing-cloth by adjusting of eccentric-wheel and length of pull rod. Cloth-pressing use pneumatic way, the cloth-pressing roll is ?125 stainless steel cladding roller, the friction between cloth cover and out-cloth roller can be guaranteed by different cloth roller pressure which caused by changing the compressed air pressure into the cylinder.
5.  Electric control cabinet unit
This unit use AC variable frequency synchronous control, and frequency converter use TAIDA or SENLAN converter.
