The specific embodiment
The utility model realizes that pressing the final executive item of yarn motion is schlagblech, by its motion of output main shaft drives.The forms of motion of schlagblech is reciprocating motion, and the continuous rotational transform that should have transmission mechanism will export main shaft between output main shaft and schlagblech is the reciprocating motion of schlagblech.Because the utility model is the schlagblech transmission mechanism of warp knitting machine, the output main shaft of warp knitting machine need to drive a plurality of workpieces, so the output main shaft transmits power on power transmission shaft 1 by Timing Belt, other workpieces also obtain power by Timing Belt from the output main shaft, then power transmission shaft again with power transmission to schlagblech, realize the reciprocating action of schlagblech.The utility model is the reciprocating action that by eccentric, rotatablely moving of power transmission shaft 1 is converted to schlagblech 13.
Embodiment one:
The first embodiment of the present utility model provides the power transmission shaft of rotary power to be set to bent axle, as shown in Figure 2, described bent axle comprises the connecting portion between trunnion 201, connecting rod neck 202 and trunnion 201 and connecting rod neck 202, is set with connecting rod cover 203 on the connecting rod neck 202 of described bent axle.The shape of described connecting rod cover 203 as shown in Figure 4, the two ends of connecting rod cover have the first through hole 401 and the second through hole 402, described the first through hole 401 adapts with trunnion 201, by the first through hole 401 and coordinating of trunnion 201, connecting rod cover 203 is sleeved on trunnion 202 like this.Connecting rod Tao203De center is done eccentric mobilely with respect to trunnion 201 like this, and described eccentric is connecting rod cover 203 and the coordinating of bent axle, and rotatablely moving of bent axle is converted to connecting rod overlaps 203 straight reciprocating motion.As shown in Figure 3, then overlap the second through hole 402 stationary links 204 of 203 by connecting rod, finally schlagblech 205 is fixed on the top of connecting rod 204.The linear reciprocation action of connecting rod cover 203 just drives schlagblech 205 straight reciprocating motions like this, has realized the action of pressure yarn.
Embodiment two:
As shown in Figure 1, the second embodiment of the present utility model provides the power transmission shaft of rotary power to be set to d-axis, is provided with eccentric wheel 2 on described power transmission shaft 1, and the described eccentric wheel outside is set with connecting rod 6.Described eccentric is eccentric wheel 2 and the coordinating of connecting rod 6, and rotatablely moving of power transmission shaft 1 is converted to the straight reciprocating motion of connecting rod 6; , by at the fixing schlagblech of the other end of described connecting rod 6, so just rotatablely moving of power transmission shaft 1 is converted to the straight reciprocating motion of schlagblech again, realization pressure yarn moves.
Further, be converted to the reciprocal amplitude of oscillation motion of schlagblech around fixed pivot for the straight reciprocating motion with schlagblech.Fixing balance staff pedestal 3 on the warp knitting machine frame, the rotating balance staff 4 that is connected with on described balance staff pedestal 3, be fixed with the first swing arm 5 and the second swing arm 7 on described balance staff 4.Described the first swing arm 5 is flexibly connected with connecting rod 6, and described the second swing arm 7 is connected with first connecting rod 9 by clutch shaft bearing 8; Described first connecting rod 9 front ends are connected with second connecting rod 10 by the second bearing 11, the other end of described second connecting rod 10 is rotatably connected on balance staff pedestal 3, here the other end of second connecting rod 10 is pivot point 12, and described schlagblech 13 is fixed on second connecting rod 10.Like this, power transmission shaft 1 band movable eccentric wheel 2 rotations, eccentric wheel 2 promotes the first swing arm 5 by connecting rod 6, because the first swing arm 5 is fixing with balance staff 4, balance staff 4 is rotating to be connected on balance staff pedestal 3, the second swing arm 7 is fixed on balance staff 4; So swinging, the first swing arm 5 causes that the second swing arm 7 swings.Because the second swing arm 7 is connected with first connecting rod 9 by clutch shaft bearing 8; Described first connecting rod 9 front ends are connected with second connecting rod 10 by the second bearing 11, the other end of second connecting rod 10 is pivot point 12, the swing of the second swing arm 7 can promote second connecting rod 10 and swing around pivot point 12, again because schlagblech 13 is fixed on second connecting rod 10, so schlagblech 13, around pivot point 12 reciprocally swingings, realizes pressing the yarn motion.
Because warp knitting machine is in the braiding process, schlagblech 13 is high speed reciprocating motions, between first connecting rod 9 and second connecting rod 10, are connected and are connected with clutch shaft bearing with the second bearing 11 between first connecting rod 9 and the second swing arm 7, can reduce the friction at connected node place, extend the service life of schlagblech transmission mechanism.
Although more than described the specific embodiment of the present utility model, but those of skill in the art in the art are to be understood that, these only illustrate, and can make various changes or modifications to these embodiments, and not deviate from principle of the present utility model and essence.Scope of the present utility model is only limited by appended claims.
