1.3.3.4 Temperature control: Groups of temperature auto-control system for predrying chamber and drying chamber

1.3.3.5 Not supply Inclined-top steam hood (Supply by user)and supply 2 No. 6 axial flow fans.

1.3.3.6 Each group of predrying cylinders has two temperature control point ,and the combined drying cylinders have one .Temperature is controlled precisely with PID, setting in the OP screen, PLC, proportional valve, and membrance valve

1.3.3.7 Evaporation capacity 800kg/h

1.3.4 Dry area

Single-side waxing device. Number of the main and small split rods according to the number of the warp beam creels.

1.3.5 Headstock

1.3.5.1 Dragging and winding driven by two AC motors. The max. winding tension 6KN.

Max. length of beam 3250mm

1.3.5.2 The weaving beam can be winded in turn and reversely, which meets the requirement of double-beam shuttleless loom with wide width

1.3.5.3 All are adopted with pneumatic control, such as weaving beam pressurization, braking, lifting & doffing weaving beam, tension roller tension, measuring roller lift ,zigzag lift and so on.

1.3.5.4 Length scale(cm)

1.3.5.5 Zigzag reed jiggles left or right, up or down. Lift is adopted with pneumatic control. The body is made of aluminium alloy and sealed totally.

1.3.5.6 Printing spray device. Length measurement and marking device

1.3.5.7 Dragging roller coated with rubber is driven by an 7.5kw inverter motor(LENZE), and weaving beam winding is driven by an 22kw inverter motor(LENZE)

1.3.5.8 SIEMENS human machine interface, in English

1.3.5.9 This machine is adopted with American STRANDBERG moisture monitor to control moisture regain.

1.3.6 Electrical control

1.3.6.1 With 7-unit inverter to drive individually. Parameters of GA308serial sizing machine are checked and controlled timely by one set of SIEMENS,S7-300 PLC and upper working station.

1.3.6.2 Colorful human machine interface. This computer can control both each unit in-phase according to the set elongation and each technological parameter in sizing course, including temperature PID control, pressure linear control, moisture regain control, Feed-in and wet area elongation auto-control, dry area elongation and tension auto-control , winding and unwinding constant tension control.

1.3.6.3 Have the function of storage and memory for each technological parameters ,management date, .and working state curve, and displaying the troubles .
