● Doffing device configuration: a doffing roller 210 mm diameter, 70 ° shore hardness rubber coated, a 100 mm diameter of yarn guide roller pressure, pneumatic, a tension guide roller diameter 100 mm, the second root is to turn into the sizing tank submerged roller guide roller, three diameter100 mm for chrome roller guide roller.
● press sizing device configuration: two submerged roller, diameter 180 mm, stainless steel roll cladding. A sizing roller, diameter 238 mm, outsourcing stainless steel, a grouting roller, 210 mm diameter, 70 ° coated shore hardness rubber, used for first pressure. another sizing roller, 238mm diameter, outsourcing stainless steel, a grouting roller, diameter 210 mm, 70 °shore hardness rubber, used for main pressure, the force controlled by PLC automatically, with a set of 0 to 40 kn grouting force control device. Able to set the main pressure small linear follow the speed of the machine.
● each sizing tank all driven by two AC inverter motor, one for guide yarn roller drive, one for sizing roller drive。
● After the bottom of the sizing tank has warp yarn channels, equipped with a guide roller, a pedal operation.
● Each sizing tank has a stainless steel wet dividing rod, branch drive
●Have flat structure
●The drying unit consists of 12pcs 800 mm diameter drying cylinder, there are nine exterior coating teflon, divided into three separate components, steel structure, steel plate side part.
●Divided into five groups of heating and temperature automatic control, each group steam piping respectively have a diaphragm valve, each group of the first cylinder is equipped with a set of PT100 temperature sensor in the stainless steel tube, respectively sampled signal to the corresponding temperature control module, respectively by signal converter to control the corresponding film valve switch state
