Type GA308 –300Sizing Machine

GA308-300 

1.3   Component

1.3.1  Warp beam creel  

1.3.1.1  Type: Wheel support,Working width: 1800mm； Max. dia. Of warp beam: 800mm

1.3.1.2  Number of warp beam 20 (not including beam), 4 beams per unit, vertical placement , Footplate between two units for operating. 

1.3.2  Sizing box 

1.3.2.1  Double immersion and double squeezing. Two sizing boxes fall down horizontally. The construction of sizing box is completely same. Two pieces of warp separately pass through a Leading roller, a tension roller, a couple of immersion roller, a sizing roller with lower pressure, a squeezing roller, a sizing roller with high pressure and a squeezing roller, then enter into cylinder drying chamber

1.3.2.2  Synchronous pneumatic squeezing in both side, high pressure varies linearly with machine speed

1.3.2.3  Pressure: No.2 squeezing roller: 0-40KN，pressure varies linearly with machine speed. No.1 squeezing roller：0-10KN，set steplessly. 

1.3.2.4  Frame is composed of steel sheet. Both inner layer and outer layer of the body is made of stainless steel.

1.3.2.5   The size in each sizing box is circulated by a circulation pump to meet preheating box and sizing box. The level height of the sizing box is controlled by adjusting the angle of level plate. The level height of the preheating box is controlled by the Float level controller.

1.3.2.6  Sizing roller is driven by an 4kw inverter motor(LENZE), and leading roller is also driven by an 4kw inverter motor(LENZE Germany) 

1.3.2.7   Temperature is controlled precisely with PID, setting in the OP screen, PLC,  proportional valve, and membrance valve.

1.3.3  Drying chamber 

1.3.3.1  Structure: Drying chamber is composed of 12 drying cylinders of stainless steel with Φ800mm., which max. working pressure 0.35Mpa.

1.3.3.2  Placement: 8  predrying  cylinders with teflon coating 

1.3.3.3  The drive is divided into three groups, two groups for predrying, and one for combined drying. The combined drying drive is of  positive drive by chain and chain wheel. All cylinders are driven by a 7.5kw inverter motor(LENZE Germany) through side shaft .

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 .
