Abstract

The utility model discloses a seven-rod beating-up mechanism of a weaving machine, which relates to the technical field of beating-up mechanisms of weaving machines. The seven-rod beating-up mechanism of the weaving machine comprises a first crank handle AB, a first connecting rod BE, a second crank handle CD, a second connecting rod DF and a rotating shaft GH; the first crank handle AB and the first connecting rod BE are connected in series sequence; the second crank handle CD, the second connecting rod DF and the rotating shaft GH are connected in series in sequence; the first crank handle AB and the second crank handle CD are respectively connected with a frame; a rocker shaft EGF connected with a working component is connected between the first connecting rod BE and the second connecting rod DF; the first crank handle AB is connected with a first motor; and the second crank handle CD is connected with a second motor. The seven-rod beating-up mechanism of the weaving machine achieves the purposes that the structure is simple; the two ends of the rocker shaft can move synchronously; the torsional vibration of the rocker shaft is decreased; and stable movement in a high-speed running process is ensured.

Description

A kind of loom seven bar beating-up mechanisms

Technical field

The utility model relates to the technical field of loom beating-up mechanism.

Background technology

The beating-up mechanism of loom use now, two covers, four bar linkages are installed respectively in the frame of the loom left and right sides, but only use a motor, the right side linkage is near from motor, the left side linkage then passes to the left side through main shaft and gear from motor side, because the about 2200-4000mm of reed width of loom, rotating speed is high again, the bent axle of air-jet loom turns around and has only a few tens of milliseconds, and the motion in rocker left side is than the motion delay of motor side.In the high speed weaving process, the motion in rocker left side is in the quick alternation state that lags behind and catch up with always, and the linkage of both sides drives same parts rocker, and rocker produces torsional oscillation as a result.

The utility model content

The utility model purpose provides a kind of simple in structure, and the rocker two ends can be synchronized with the movement, and reduces the torsional oscillation of rocker, and the motion when guaranteeing to run up is loom seven bar beating-up mechanisms stably.

A kind of loom seven bar beating-up mechanisms, comprise the first crank AB, first connecting rod BE that is connected in series successively and the second crank CD, second connecting rod DF, the turning cylinder GH that is connected in series successively, the first crank AB is connected with frame respectively with the second crank CD, connects workpiece rocker EGF between first connecting rod BE, the second connecting rod DF; The first crank AB goes up and connects first motor, and the second crank CD goes up and connects second motor.

Sliding pair is connected between turning cylinder of the present utility model and the frame.

The utility model adopts technique scheme, compared with prior art has following advantage: the utility model Two-Degree-of-Freedom mechanism, increase one degree of freedom, changing original four-bar mechanism is seven-bar mechanism, settled a mandrel at the core of rocker, rocker can be swung on mandrel, and this can have a spot of slip mandrel in chute.Target is the motion of balance rocker on length, and the motion when guaranteeing to run up is steady.New adjusting factor is presented as under the preceding topic that keeps the power of beating up, and when two lateral movements are inconsistent, allow mandrel make a movement slightly, and rocker keeps rotating easily always, changes nervous formula swing in the past.For specific action and the minimizing vibration of finishing loom, the design new mechanism combines traditional loom mechanism and modern technologies, adds flexible factor in the rocker motion, and rocker moves to become and coordinates easily.

Fig. 2 is structural type figure of the present utility model.

Fig. 3 is the structural representation of the utility model rocker and turning cylinder.

The specific embodiment

Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:

As shown in Figure 1 and Figure 2, a kind of loom seven bar beating-up mechanisms, comprise the first crank AB, first connecting rod BE that is connected in series successively and the second crank CD, second connecting rod DF, the turning cylinder GH that is connected in series successively, the first crank AB is connected with frame respectively with the second crank CD, connects workpiece rocker EGF between first connecting rod BE, the second connecting rod DF; The first crank AB goes up and connects upward connection second motor 2 of first motor, 1, the second crank CD.

Sliding pair is connected between turning cylinder of the present utility model and the frame 3.

Fig. 1 represents the sketch of seven bar beating-up mechanisms.Beating-up mechanism comprises two cover minor structure, rocker and turning cylinders etc., and every cover minor structure comprises crank, connecting rod etc.There are two driving forces in mechanism, and two motors drive left and right sides bent axle respectively, bent axle band left and right sides crank, and crank up drives the rocker swing.Two cover minor structures drive same workpiece rocker.

Fig. 2 represents two degrees of freedom seven bar beating-up mechanism configuration pictures, and rod member CD and AB are cranks, and rod member BE and DF are connecting rods, and rod member EGF is a workpiece, and ACH is a frame, and GH is a turning cylinder.Crank AB and CD do 360 ° of rotations in the same way, two crank equal in length, and two length of connecting rods equate.Two cover minor structures drive rocker simultaneously, and two minor structure steps are in full accord.

Fig. 3 represents rocker and rotation shaft structure schematic diagram, and rocker can turn round on turning cylinder, and the turning cylinder band rocker and slided along guide rail 4.Be positioned at the core of rocker 6 as figure turning cylinder 5, guide rail is embedded in the frame 3, and guide rail 4 has two covers, lays respectively at both ends, the rocker left and right sides.Can not relatively move between turning cylinder 5 and the rocker 6, turning cylinder 5 provides passive constraint for the motion of workpiece, and the motion not exclusively symmetrical for both sides provides activity space.With rotation shaft structure, allow rocker 6 to twist relatively, use the result but to reduce relative twisting, reduce the torsional oscillation of rocker 6.
