Description

Warp loom yarn tension compensating device
Technical field
The utility model relates to a kind of textile machine, particularly a kind of warp loom yarn tension compensating device.
Background technology
Existing warp loom yarn tension compensating device is more traditional, because jacquard comb plays jacquard weave effect in braiding, so yarn warp run-in is different, therefore adopts the creel warp let-off, and therefore the tension force of every one thread is all different.
As shown in Figure 1, traditional tensioner mainly by fan-shaped sprocket 1-7, returning spring 1-5, be fixed on left and right sidesing wall plate set bolt 1-1, be arranged on rotating tension rail on machine and the tension piece 1-9 that is fixedly mounted on described tension rail forms; Wherein, fan-shaped sprocket 1-7 is connected by chain 1-6 with returning spring 1-5, the other end of returning spring 1-5 is fixed on wallboard by dog 1-3, clamp 1-2, set bolt 1-1, this compensation arrangement makes tension piece 1-9 reciprocating motion by the elastic force of returning spring 1-5, thereby reaches the tension stability of yarn.When warp knitting machine is worked, main shaft often turns around, looping mechanism carries out a reciprocating motion, when lopping, when knitting needle pads yarn at every turn and presses yarn, the tension band dynamic tension sheet 1-9 to yarn, and drive returning spring 1-5 by fan-shaped sprocket 1-7, by returning spring 1-5 pulling force, guarantee that tension piece 1-9 swings up and down once, compensates yarn tension with this.During existing warp knitting machine work, yarn is from creel, pass through yarn passing rod, lever jack, tension piece 1-9, again through knitting braiding, by said method, compensate yarn tension, with this, guarantee carrying out smoothly of lopping campaign, but, yarn has following shortcoming when weaving with this tension compensating mechanism, during due to braiding, lopping only moves reciprocatingly, when accordingly yarn being produced to tension force, be pad yarn and press the yarn stage, now can complete the tension force of yarn is controlled by this device, and during lopping campaign the needed tension compensating of yarn not only in the time of these two, when traversing and lopping, tension force also needs to compensate in time, when yarn during in lopping suffered tension force larger, and knitting needle is when pendulum is about to knocking over to rearmost position, because yarn tension can not get timely compensation, cause excessive causing of the suffered yarn tension of knitting needle to be out of shape, thereby usually cause machine to produce snagging, thereby affect the operating rate of machine.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of and can when warp knitting machine lopping, can compensate in time tension force, can guarantee the warp loom yarn tension compensating device of the permanent tension force of yarn in knitting cycle.
The utility model solves the technical scheme that its technical problem adopts: a kind of warp loom yarn tension compensating device, comprise tension force swing arm, swing arm synchronising (connecting) rod, eccentric wheel, eccentric wheel driving mechanism and main shaft, one end of tension force swing arm is arranged on the tension rail of warp knitting machine, between tension force swing arm on differential tension bar by swing arm synchronising (connecting) rod connection for transmission, one of them tension force swing arm is by pull bar and drive swingingly eccentric wheel connection for transmission of tension force swing arm, and main shaft drives eccentric wheel by eccentric wheel driving mechanism.
Particularly, eccentric wheel driving mechanism comprises spindle synchronous wheel, eccentric synchronizing wheel, intermediate propeller shaft, Timing Belt and compensation seat, eccentric wheel and eccentric synchronizing wheel are coaxially installed on intermediate propeller shaft, intermediate propeller shaft is arranged on compensation seat, compensation seat is arranged on equipment wallboard, spindle synchronous wheel is arranged on main shaft, between spindle synchronous wheel and eccentric synchronizing wheel, by Timing Belt, connects.
Particularly, have swing arm amplitude of oscillation regulating tank in tension force swing arm, pull bar is by swing arm amplitude of oscillation regulating tank and tension force swing arm connection for transmission.
Further limit, swing arm synchronising (connecting) rod is by swing arm amplitude of oscillation regulating tank and tension force swing arm connection for transmission.
The beneficial effects of the utility model are: because warp knitting machine braiding lopping campaign is controlled by main shaft, and tension piece to swing up and down be also to be controlled by main shaft, both have synchronism, can when the warp let-off, control better yarn tension, realize better the tension compensating of yarn.
