AIR JET GAUZE MECHINERY---PQ08A& PQ08BTECHNICAL SPECIFICATIONOperating mode: main nozzle one-pass air-jet weft insertion; Reed width: 1400mm Shedding device: rocker arm shedding, tappet shedding; Speed of crankshaft: 300-500 r/min Control: left-hand operation Weft selection: one color Flange for weaver's beam: 550-600 mm Drive: electromagnetic brake (24V) Motor speed: 960 r/min (0.8KW V-belt drive)10. Dropper bar number: 4 contact bars.11. Pick density: 4-30 picks/cm12. Licker-in roller diameter: 127 mm13. Cloth roller diameter: 95/74 mmMACHINE FRAMEMachine frame comprises mainly wall plates on the left and right sides, two cross beams in the front and rear that link the plates, middle cross beam, front beam, and small supporting parts which hold the parts together into a machine body. The frame is placed on a wood block and fixed to the ground with anchor bolts. It adopts electromagnetic clutch and brake attractive transmission.TRANSMISSIONThe releasing and braking processes are both controlled by a microcomputer.WEFT INSERTIONWeft insertion mechanism uses an independent air nozzle. The process is initiated by a crank shaft. It drives the air pump by pressing a piston, letting compressed air burst out of the gate and blow the weft.CUTTERShedding cutter and blades are mounted on the weft insertion seat as an independent cutter device to cut the weft.BEATING-UPThe beating-up system has a special crank shaft which is linked to the machine base. As this shaft moves back and forth, as well as the steel buckle on the machine base, the weft inserting process is smoothly carried out.LET-OFF Interior electrical weft feeding is controlled by sensors and computer program, with the assistance of an auto tension adjustment device. Such a mechanism ensures an even feeding volume and a constant weft tension. (FOR PQ08B)TAKING-UPThe take up structure adopts worm wheel, and non-stop mechanism. The take up of cloth is conducted by the licker-in roller driven by change gears. (Electrical take up structure is added for PQ08B.)CLOTH-ROLLINGTorsion spring pressing cloth-rolling mechanism makes the removing of cloth as easy as just pressing the spring.STOPThe cutting of warp and weft is conducted by an electrical device which can stop automatically once the cutting is done. This device has a red light indicates the stop of warp and a green one indicates the stop of weft.
