The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the scissor arm device of the packaging bag introducing mechanism of the present embodiment, the clamping plate 16 that comprise pair of parallel, one end of clamping plate 16 is equipped with shear arm 2 by shaft sleeve device 22, one end of shear arm 2 is installed on the first permanent seat 1 by fastener, is positioned on the first permanent seat 1 to be provided with pivot point 19; Be vertically installed with on the second permanent seat 4, the second permanent seats 4 with the first permanent seat 1 and by the first bolt 18 a pair of cylinder 3 be installed respectively, piston rod 20 heads of cylinder 3 are connected with the bending part of shear arm 2 by the second bolt 21.As shown in figures 1 and 3, shear arm 2 adopts rectangular tube.
As shown in Figure 3 and Figure 4, the mounting structure of shaft sleeve device 22 is: an end that is positioned at clamping plate 16 is provided with perpendicular mounting hole 15, penetrates a rotating shaft 11 in the mounting hole 15, and is positioned at mounting hole 15 bottoms by clamping plate and 17 lockings of tight piece; Rotating shaft 11 stretches out in the top of clamping plate 16, supports by clutch shaft bearing 10 and the second bearing 14 respectively in the rotating shaft 11 of stretching out that axle sleeve 8 being installed, and by the effect of bearing, guarantees location and the rotation of rotating shaft 11; The aperture 12 that rotating shaft 11 between clutch shaft bearing 10 and the second bearing 14 is provided with break-through passes steel rope 13 in the aperture 12; On the axle sleeve 8 and be positioned on the axle sleeve arm of junction of rotating shaft 11 aperture of opening 12 and have hole 9; Be positioned at axle sleeve 8 the first half and by locating piece torsion spring 6 be installed, torsion spring 6 lower ends are installed on the top of clutch shaft bearing 10 by lower locating piece 7, and locating piece 5 is installed in torsion spring 6 upper ends, and upper locating piece 5 lock onto the top of axle sleeve 8 by screw 23.By the application force of torsion spring 6, give 11 1 torsional moments on its vertical direction of rotating shaft like this.
As shown in Figure 4, the mounting structure of steel rope 13 is: an end of steel rope 13 is fixed on the fixed block (not shown in FIG.), steel rope 13 other ends are wound in the rotating shaft 11 by passing aperture 12, and pass 8 perforates 9 of axle sleeve to shear arm 2 internal directs and enter the rear end, link to each other with the second bolt 21.
The winding direction of steel rope 13 is opposite with the application force of torsion spring 6.
In the actual use procedure, when cylinder 3 is constantly done fore and aft motion, drive the opening and closing movement that shear arm 2 is done Jian's cutter formula, because the effect of torsion spring 6, and the mounting structure of rotating shaft 11, drive simultaneously clamping plate 16 to the inside or outer side oscillation; Under the effect of torsion spring 6 and the mutual balancing force of antagonistic force steel rope 13, when shear arm 2 was done open and close movement, its clamping plate 16 were done the parallel motion that is parallel to two plate line of centerss all the time, and inside and outside one to the property synchronized parallel movement.Thereby make clamping plate 16 keep a straight line with the sack direction of packing sack all the time, and when shear arm 2 closed, clamping plate 16 are clamped bag mouth, the sealing of instant packed bag.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
