JR788 high speed rapier loom
Main drive: The main motor 7.5KW adopts frequency converter for speed regulation.
Weft insertion: the use of a space four-bar linkage mechanism, forward and slow reverse search, precise weft insertion action, which is beneficial to reduce driving marks.
Shedding: Electronic dobby shedding, with up to 20 heald frames.
Electrical control system: Adopt 32 -bit CPU central processing unit, frequency converter and three-phase asynchronous motor.
Lubrication cooling system: Aluminum alloy oil tank, circulating spray lubrication, oil temperature sensor is added, and water cooling is forced to achieve the purpose of cooling oil temperature.
Color selection : stepping motor controls the rotary high-speed electronic weft selector, the color selection mechanism can match up to 16 colors.
Beat-up : Double-sided conjugate cam, separated sley.
Let-off : Servo electronic let-off, digital closed-loop control of constant tension weaving, small tension fluctuation from full shaft to empty shaft
Coiling : Servo electronic coiling can realize variable weft density weaving.
Heald frame connection : It is very convenient to adjust the height of the heald frame and change varieties.
