The working process of the M-shaped bag finishing mechanism 8 is as follows: the outer packaging bag 31 that is opened is delivered to the front end of the folding plate 83, and at this moment, the thrust cylinder 817 pushes the guide rail seat 86 to move forward, thereby making the two on the guide rail seat 86 move forward. The first hemming cylinder 89 moves forward, and then the hemming cylinder 89 works to drive the folding plate 83 to move inwardly, thereby pushing the side wall of the outer packaging bag 31 to the middle, and the pressing plate 815 compresses the middle part of the outer packaging bag 31 , Fold the opening of the outer packaging bag 31 into an M shape.

Finally, refer to FIG. 13 , which is a schematic structural diagram of the sealing mechanism in the embodiment shown in FIG. 1 of the horizontal bagging machine according to the present invention.

The sealing mechanism 9 includes two sealing parts, and the two sealing parts are symmetrical with respect to the pre-compression cylinder 918, so as to realize sealing two outer packaging bags at one time.

In this embodiment, the sealing part includes a column 91, a hot-pressing mounting plate 95, a hot-pressing guide plate 96, a hot-pressing horizontal plate 98, and a lower support plate 914, and hot-pressing cylinders 99 are installed at both ends of the hot-pressing mounting plate 95. ; The lower support plate 914 is provided with a hot plate 912; the bottom of the hot pressing horizontal plate 98 is provided with a hot ring 913;

In this embodiment, a pre-compression cylinder mounting plate 916 is provided in front of the heating plate 912, and a pre-compression cylinder 918 is mounted on the mounting plate.

In this embodiment, a bakelite board 915 , a pre-compression plate 917 and a pre-compression block 919 are provided below the pre-compression cylinder 918 .

In this embodiment, a cylinder connector 910 is provided at the lower end of the hot-press cylinder 99 , and the connector is fixed on a cylinder pull block 911 .

In this embodiment, the cylinder pull block 911 is connected to the slider connecting plate 94 , and the slider 93 is arranged on the connecting plate, and the slider is located in the slide rail 92 .

The working process of the sealing mechanism 9 is as follows: the two packaging bags from the M-shaped bag sorting mechanism 8 are transported to the bottom of the pre-compression block 919 by the finished product conveying line 10, and the pre-compression cylinder 918 is activated, so that the two ends of the pre-compression block 919 are respectively pressed. Squeeze the opening of a packaging bag, then start the hot pressing cylinder 98, the hot pressing horizontal plate 98 descends and contacts the packaging bag, and then the hot ring 913 under the hot pressing horizontal plate 98 heat seals the opening of the packaging bag.

The horizontal bagging machine of the present invention is designed with a double-track, double-channel packaging method, which makes the machine run more smoothly, with high speed and high packaging efficiency; Blocky items are required to be packaged together at the same time. For a single material that is relatively heavy, the packaging bag is thicker and has a strong three-dimensional appearance; no empty bags are used during packaging, and packaging materials are not wasted; compared with manual packaging machines, each bag of this packaging machine can Cost savings of more than 20%, while improving the added value and grade of products.

It is not difficult for those skilled in the art to understand that the horizontal bagging machine of the present invention includes any combination of parts in this specification. Due to space limitation and to make the description concise, these combinations are not introduced in detail here, but after reading this description, the scope of the present invention constituted by any combination of the parts constituting this description is self-evident.
