Further as a preferred embodiment, the device also comprises an outlet device 70, wherein the outlet device is provided with an outlet belt 71, and the outlet belt 71 is positioned in front of the push rod; the discharging device also comprises an automatic bag binding mechanism.

In operation, food enters the packaging machine from the feeding device 20, falls onto the push rod 51 of the pushing device 50 under the action of the feeding belt, and then the press rod 53 presses downward to press the food.

And a preformed package (having a single-sided opening) is fed from the bag feeder 30 into the packaging machine. The bag lifting mechanism 60 (typically including a lifting arm with suction cups at the lower end of the lifting arm) then lifts the individual bags and, after the individual bags are lifted, the bag openings are slightly opened by their own weight. At this time, the bag opener 40 starts operating.

In the free state, the front ends of the two bag opening mechanisms 200 are close to each other. And the movable plate 320 and the fixed plate 310 are also close to each other. And the rear side of the movable plate 320 is hinged with the rear side of the fixed plate 310. And the drive mechanism, typically an air cylinder, may be fixedly mounted to the synchronization rod 290.

When a bag needs to be opened, the pushing mechanism (for example, a pushing cylinder) pushes the synchronizing rod 290 forward, the synchronizing rod 290 drives the two bases 210 to move forward synchronously, so that the opening arm 300 enters a predetermined station, and when the opening arm 300 moves forward, because the rotating pin 270 always adheres to the guide surface 251, because the guide block 250 is relatively fixed, after the bases 210 move forward, referring to fig. 3, because the height behind the guide surface 251 of the guide block 250 is greater than the height in front of the guide surface, the oscillating rod 260 oscillates under the action of the torsion spring, and because the oscillating rod 260 is fixedly connected with the rotating shaft 220, the rotating shaft 220 is driven to rotate by the rotation of the oscillating rod 260, and because the rotating shaft 220 is fixedly connected with the opening arm 300, the oscillating of the oscillating rod 260 can drive the opening arm 300 to oscillate in the left-right direction. Then, in cooperation with the action of the driving mechanism, the movable plate 320 is relatively rotated upward. In this combined operation, the opening arm 300 can open the bag opening of the packaging bag in the left-right direction and the up-down direction. And the forward movement and the left-right swinging of the opening mechanism are synchronously completed, the action is finished at one time, and the structure is simpler and more reasonable.

When the packing bag is opened by the bag opening device 40, the push rod 51 moves forward, and the food is fed into the packing bag. The pusher 51 then continues to push forward, feeding the food product and the package into the outfeed belt 71. Finally, the pressure lever 53 is released, and the push rod 51 moves back rapidly. After the push rod 51 is reset, the pushing mechanism of the bag opening device 40 drives the base 210 to move back, and due to the combined action of the torsion spring and the swing rod 260, the rotating shaft 220 swings inwards, that is, the opening arm retracts inwards, and the bag opening device is reset. Waiting for the next job.

After the food is fed into the discharging belt 71, the bag opening can be packaged separately by installing an automatic bag binding mechanism on the packaging machine. The bag tying mechanism shrinks the bag opening through the mechanical arm and then ties the bag opening by a tie. Of course, this sealing operation may also be performed manually.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
