[0049] Furthermore, the feeding rack 10 is used to support the assembly of other parts of the feeding mechanism 100, and the bottom of the feeding rack 10 is placed on the ground of the external environment. It can be understood that the user can design the specific structure of the feeding rack 10 according to actual use requirements.

In this embodiment, the material placement drive member 22 is a cylinder. The first feeding part 211 and the second feeding part 212 are arranged in parallel along the first direction. The first feeding part 211 and the second feeding part 212 are both in the shape of a straight plate. The feeding table 21 is driven to move in the first direction by the material placement driving member 22 to switch the first feeding part 211 or the second feeding part 212 to correspond to the feeding position; so that when one of the first feeding part 211 and the second feeding part 212 feeds packages to the external grasping structure, the worker can load and stack packages to the other one, ensuring that the worker does not need to stop the machine when loading packages, thereby improving production efficiency.

[0051] Further, the first adjustment hole 215 is in the shape of a strip extending along the second direction, and the second adjustment hole 216 is in the shape of a strip extending along the second direction. In the second direction, the length of the first adjustment hole 215 is L mm, and the length of the second adjustment hole 216 is equal to the length of the first adjustment hole 215; in the first direction, the spacing between adjacent first adjustment holes 215 and second adjustment holes 216 is H mm. Wherein, L≥H. In this embodiment, adjacent first adjustment holes 215 and second adjustment holes 216 are staggered in the second direction to ensure that the first adjustment holes 215 and the second adjustment holes 216 in the second direction are continuously staggered, and there is no position in the second direction where the film guide frame 30 cannot be adjusted and fixed. It can be understood that the first feeding part 211 and the second feeding part 212 are both arranged with the first adjustment hole 215 and the second adjustment hole 216, and the structure of the first feeding part 211 is the same as that of the second feeding part 212, so as to ensure that both the first feeding part 211 and the second feeding part 212 can supply materials to the outside.

The extension portion 32 is perpendicular to the feeding table 21, and the extension portion 32 passes through the through opening 235. The extension portion 32 abuts against the outer edge of the package to guide the stacking of the package. It can be understood that the number of the film guide frames 30 is multiple, and the film guide frames 30 are respectively arranged on the first feeding portion 211 and the second feeding portion 212, and the multiple film guide frames 30 are respectively fixed on the first feeding portion 211 and the second feeding portion 212 according to the specifications and shapes of the packages.

[0056] Furthermore, the feeding mechanism 100 also includes a lifting assembly 40, which is arranged at the feeding position, and the lifting assembly 40 is used to drive the lifting platform 23 to move up and down.

The lifting screw 41 is rotatably connected to the feeding rack 10, and the lifting screw 41 is in the shape of a long strip. The extension direction of the lifting screw 41 and the extension part 32 are the same. The lifting screw 41 passes through the lifting platform 42 and is threadedly connected to the lifting platform 42. The lifting screw 41 can drive the lifting platform 42 to move along the lifting screw 41 when it rotates. The lifting platform 42 is in the shape of a straight plate, and the lifting platform 42 is arranged parallel to the feeding platform 21. The lifting drive 43 is connected to the lifting screw 41 to drive the lifting screw 41 to rotate, and the lifting drive 43 is installed on the feeding rack 10. The locking block 44 is movably connected to the lifting platform 42, and the locking block 44 can move relative to the lifting platform 42 along the second direction. The locking block 44 is used to be plugged with the lifting platform 23 to relatively lock the lifting platform 23 and the lifting platform 42, that is, when the locking block 44 is plugged with the lifting platform 23, the lifting platform 23 moves up and down together with the lifting platform 42. The locking drive member 45 is connected to the locking block 44, and the locking drive member 45 is used to drive the locking block 44 to move. The movable end of the locking drive member 45 is connected to the locking block 44 to adjust the plugging state of the locking block 44 and the lifting platform 23. In actual use, when the first feeding part 211 is located at the feeding position, the locking drive 45 drives the locking block 44 to plug into the lifting platform 23 on the first feeding part 211. At this time, the lifting drive 43 drives the lifting screw 41 to rotate, so that the lifting platform 42 and the lifting platform 23 on the first feeding part 211 can be driven to move up and down together, thereby realizing the feeding operation at the first feeding part 211. When it is necessary to switch to the second feeding part 212 for feeding, the locking drive 45 drives the locking block 44 to separate from the lifting platform 23 of the first feeding part 211, and the material placement drive 22 drives the second feeding part 212 to move to the feeding position. The locking drive 45 drives the locking block 44 to plug into the lifting platform 23 of the second feeding part 212. At this time, the lifting platform 42 and the lifting platform 23 on the second feeding part 212 can be driven to move up and down together, thereby realizing the feeding operation at the second feeding part 212. In this embodiment, the lifting driving component 43 is a motor, and the locking driving component 45 is a cylinder.

[0057] Furthermore, the locking block 44 includes a connecting portion 441 and a locking portion 442. The connecting portion 441 is in the shape of an elongated strip, extends along a first direction, and is connected to the locking drive member 45. The locking portion 442 is in the shape of an elongated strip and extends from the connecting portion 441 to the lifting platform 23, extends along a second direction, and is used to be inserted into the lifting platform 23. In this embodiment, the extending direction of the connecting portion 441 is perpendicular to the extending direction of the locking portion 442, and a plurality of locking portions 442 are provided, and each locking portion 442 is arranged at intervals along the connecting portion 441 to ensure the reliability of the plug-in connection between the locking block 44 and the lifting platform 23.
