Abstract
The invention relates to a scissors clamp arm device for a packaging bag guide-in mechanism. The scissors clamp arm device comprises a pair of parallel clamp plates. A scissors arm is disposed at one end of each clamp plate through a shaft sleeve device. One end of each scissors arm is disposed on a first holder through a fastener, and the first holder is provided with a rotation point. A second holder is perpendicular to each first holder. A pair of cylinders is disposed on each second holder through a first bolt. The head of a piston rod of each cylinder is connected with the bend of the corresponding scissors arm through a second bolt. The scissors clamp arm device is reasonable in structure and convenient to manufacture and mount. The scissors arms are connected with the clamp plates through the shaft sleeve devices. When the scissors arms arc around the rotation points, the clamp plates are allowed to straightly move towards an opening of a packaging bag, so that the clamp plates are guaranteed to constantly move in or out in a direction parallel to the opening of the bag. The scissors clamp arm device is highly practical, flexible to act and simple and reliable to operate.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention 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, comprise the clamping plate 16 of pair of parallel, one end of clamping plate 16 is provided 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 and is provided with pivot point 19; Be vertically installed with on the second permanent seat 4, the second permanent seats 4, by the first bolt 18, a pair of cylinder 3 be installed respectively with the first permanent seat 1, 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: the one end that is positioned at clamping plate 16 is provided with perpendicular mounting hole 15, penetrates rotating shaft 11 in mounting hole 15, and is positioned at mounting hole 15 bottoms and locks by clamping plate tight piece 17; Rotating shaft 11 stretches out in the top of clamping plate 16, in the rotating shaft 11 of stretching out, is supported axle sleeve 8 is installed respectively by clutch shaft bearing 10 and the second bearing 14, by the effect of bearing, ensures location and the rotation of rotating shaft 11; In the rotating shaft 11 between clutch shaft bearing 10 and the second bearing 14, be provided with the aperture 12 of break-through, in aperture 12, pass steel rope 13; On 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, 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.Like this by the application force of torsion spring 6, give 11 1 of the rotating shafts torsional moment in its vertical direction.
As shown in Figure 4, the mounting structure of steel rope 13 is: one end of steel rope 13 is fixed on fixed block (not shown in FIG.), steel rope 13 other ends are wound in rotating shaft 11 by passing aperture 12, and enter rear end through 8 perforates 9 of axle sleeve to shear arm 2 internal directs, are connected with the second bolt 21.
The winding direction of steel rope 13 is contrary with the application force of torsion spring 6.
In actual use procedure, in the time that cylinder 3 constantly does fore and aft motion, drive shear arm 2 does the opening and closing movement of Jian's cutter formula, due to the effect of torsion spring 6, and the mounting structure of rotating shaft 11, drive clamping plate 16 to the inside or outer side oscillation simultaneously; Under the effect of torsion spring 6 and the mutual balancing force of antagonistic force steel rope 13, in the time that shear arm 2 does open and close movement, its clamping plate 16 do the parallel motion that is parallel to two plate line of centerss all the time, and inside and outside one to property synchronized parallel movement.Thereby make clamping plate 16 keep a straight line with the sack direction of packaging sack all the time, and in the time of shear arm 2 closed, clamping plate 16 are clamped bag mouth, the sealing of instant packed bag.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of amendment.
