Description

Technical Field

[0001] The present invention relates to packaging equipment, in particular to an automatic food packaging machine. Background Art

[0002] After food is packaged, it is often necessary to box the material for subsequent transportation and sales. One type of food requires nitrogen to be filled into the packaging bag during packaging to slow down its oxidation and deterioration. In order to reduce the size of the packaging box, the material is often required to be loaded vertically into the packaging box. However, this type of nitrogen-filled packaging is prone to overturning under the action of gravity during transportation. The transportation and boxing process often requires manual participation, which is labor-intensive for workers and the efficiency and quality of boxing are low. Due to the irregular shape of the inflatable packaging and the sideways or vertical placement of the packaging bag, there are currently no robots or suction cups that can grab it. In addition, the number of boxes is different, and the suction cup cannot grab it.

Of course, the first, second, third, fourth, fifth, sixth, and seventh clamping plates are provided with side guards on both sides.

The first, second, third, and fourth lift plates are connected to corresponding lifting drive cylinders, and these lift plates can push materials into the packaging box below. The machine also includes a sixth linear guide 56 provided on the frame, on which a movable seat is slidably mounted. The movable seat is connected to a corresponding synchronous belt, which is in transmission connection with a corresponding motor. The movable seat is connected to a push rod 55, which can push the third movable frame 53 and the fourth movable frame 54 to move.

[0030] The working principle of the present invention is as follows: the material is transported to the feeding end of the first feeding chamber 14 through the front conveyor belt, and at this time the first cylinder 4 drives the first rotating shaft 13 to rotate, so that the first push plate 2 swings up, which facilitates the continuous feeding of the material into the first feeding chamber 14, and because the first feeding chamber 14 limits the material, the material maintains a vertical state during the transportation process of the first feeding chamber 14, and then the first cylinder 4 drives the first rotating shaft 13 to reverse, so that the first push plate 2 swings down, blocking the feeding port of the first feeding chamber 14, and the first movable frame 5 drives the first push plate 2 to move, pushing the material backward. When the material is pushed to the first feeding chamber 14, the first movable frame 5 drives the first push plate 2 to move, pushing the material backward. After the material enters the second feeding cavity 20, the second push plate 19 descends to separate the first feeding cavity 14 from the second feeding cavity 20. Then the feeding plate 22 moves the second feeding cavity 20 toward the rotating platform 8. At the same time, the second movable frame 15 also drives the second push plate 19 to move synchronously with the second feeding cavity 20 to ensure that the material is stably in the second feeding cavity 20 and moves toward the rotating platform 8. When the material is delivered to the rotating platform 8, the first partitions 25 set on the left and right and the second partition 24 at the rear have risen. At this time, the left and right sides of the arranged materials are supported and limited by the two first partitions 25, and the front side is supported and limited by the second partition 24. The rear side is limited by the second push plate 19, and then the second partition 24 in front rises, and the second push plate 19 also rises at the same time, so that the rear side of the arranged materials is supported and limited by the second partition 24 in the rear. At this time, a group of first and second partitions have all risen to surround the storage cavity 28, limit the arranged materials, and ensure that the materials are in a vertical state. After that, the feeding plate 22 and the second push plate 19 move back, and repeat the above steps to send another row of materials to another group of first and second partitions on the rotating platform 8 and be surrounded by the first and second partitions. In this embodiment, since there are six groups of first and second partitions and they are arranged in a The front and back are symmetrically arranged, so a maximum of three groups of materials can be transported at a time. Then the rotating platform 8 rotates, so that the materials are rotated to the clamping manipulator assembly. When there are three groups of materials on the rotating platform 8, the rotating frame 12 drives the fourth movable frame to rotate to the clamping station. Then the second lifting frame 49 descends, driving the fourth, fifth, sixth and seventh clamping plates to descend. At the same time, the first and second partitions here also descend to make way. Then the first motor 51 drives the fourth and fifth clamping plates to approach each other. At the same time, the sixth and seventh clamping plates will also approach each other under the action of the spring, so that the three groups of materials can be clamped on the fourth and sixth clamping plates respectively.Between the sixth and seventh clamping plates, and between the seventh and fifth clamping plates, the push rod 55 is now connected to the fourth mobile frame 54. The push rod 55 pushes the fourth mobile frame 54 to move above the packaging box 11. Then the second lifting frame 49 descends, driving the fourth, fifth, sixth and seventh clamping plates to penetrate into the packaging box 11. The corresponding ejector plates push the materials down into the box, allowing the materials to be stably fed into the packaging box. After that, they return to the clamping station, and the packaging operation is repeated in this way. Similarly, when two groups of materials are being packed, the rotating frame 12 will drive the third mobile frame 53 to rotate to the clamping station and connect the push rod 55 to the third mobile frame 53, controlling the movement of the second and third clamping plates to clamp and transfer the two groups of materials for packaging.

[0031] With the structure of the present invention, the materials are always positioned by corresponding stops during the transportation process, ensuring that the materials can be transported vertically all the time. Finally, the vertical materials are grabbed in batches by the robot assembly and sent into the packaging box, realizing automated transportation and packaging throughout the process, which greatly reduces the labor intensity of workers and improves the efficiency and quality of material packaging.
