Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides the following embodiments:

the packaging bag cutting mechanism with high cutting flatness comprises an air cylinder 4, a cutting plate 7, a pressing plate 10 and a cutter 12, wherein the air cylinder 4 is at least provided with 3 groups, and the 3 groups of air cylinders 4 adopt the same power source.

Even frame 5 is the L form, and the lateral wall and the cylinder 4 of even frame 5 are connected, and even the straight end of frame 5 has installed cutter 12, and cutter 12 is used for cutting, and cutting plate 7 extends to one end at cylinder 4, cuts the cutter 12 that groove 8 is used for holding the extension.

The side surface of the pressing plate 10 is attached to the inner surface of the cutting plate 7 for fixing the packaging bag, and the pressing plate 10 moves along with the connecting frame 5.

As a preferred scheme of the utility model, cylinder 4 is installed on first installation crossbearer 3, and first installation crossbearer 3 is installed and has been seted up installation notch 2 lateral walls on the plate holder 1 in the packagine machine.

As another preferred scheme of the utility model, another lateral wall at installation notch 2 is installed through second installation crossbearer 6 to cutting plate 7, is provided with guide arm 9 between second installation crossbearer 6 and the first installation crossbearer 3, all is provided with the same footpath that supplies guide arm 9 to pass on even frame 5 and the clamp plate 10 and leads to the groove, through guide arm 9 and even logical groove on frame 5 and the clamp plate 10, increases the guide effect, ensures even cutter 12 and the smooth-going removal of clamp plate 10 on even frame 5.

As the utility model discloses a another preferred scheme even links to overlap 11 through the spring and connects between frame 5 and the clamp plate 10, and guide arm 9 runs through the spring and links to overlap 11, connects stably, and the spring even overlaps 11 and plays the effect that resets after the cutting, is connected with reset spring 13 even between frame 5 middle part and the clamp plate 10, and the spring even overlaps 11 and reset spring 13 can both play the effect that resets.
