[0035] Referring to Figure 1 、 Figure 5 、 Figure 6 As shown, a lifting bag clip mechanism of the present utility model includes:

[0036] A frame 1, and a material feeding opening 11 is arranged on the frame 1;

[0037] A bag clip device, including a bag clip connecting frame 2 slidably connected to the frame 1 and two bag clip assemblies 3 installed on the bag clip connecting frame 2, arranged oppositely and on both sides of the material feeding opening 11. Each bag clip assembly 3 includes a frame body 31, a bag clip body 32 rotatably connected to the frame body 31, and a telescopic member 33 for driving the bag clip body 32 to rotate along the frame body 31;

[0038] A lifting driving device 4, installed on the frame 1 and driving the two bag clip assemblies 3 to synchronously descend or rise along the frame 1 to insert or extract a packaging bag.

[0039] Through the bag clip assembly 3, the packaging bag can be accurately inserted and opened, ensuring that the packaging bag can accurately dock with the material feeding opening 11, avoiding packaging failures caused by deviations, reducing the manual operation requirements of the operator, lowering the labor intensity, and improving the convenience and efficiency of the operation.

[0040] In one embodiment, referring to Figure 1 As shown, the lifting driving device 4 includes lifting electric cylinders 41 arranged at the transverse two ends of the frame 1, and the driving ends of the lifting electric cylinders 41 are connected to the frame body 31. The lifting electric cylinders 41 are driven by servo motors, can achieve precise actions and multi-instruction operations, and the speed is adjustable.

[0041] In one embodiment, referring to Figure 3 As shown, the bag clip connecting frame 2 includes a cross beam 21 connected between the frame bodies 31 of the two bag clip assemblies 3 respectively. A vertical guiding groove 12 extends in the frame 1, and a guiding bearing 22 cooperating with the vertical guiding groove 12 is installed in the middle of the cross beam 21.

[0042] Specifically, the vertical guiding grooves 12 are symmetrically arranged at the longitudinal two ends of the frame 1.

[0043] Through the above arrangement, the vertical guide groove 12 provides a good guiding effect, ensures the stability and accuracy of the bag clamp assembly 3 during the lifting process, reduces the deviation during the movement, and improves the accuracy of the overall packaging process.

[0044] In one embodiment, referring to Figure 4 As shown, the frame 31 includes two connecting plates 311 , a rotating frame 34 rotatably connected to the frame 31 is installed between the two connecting plates 311 , and the telescopic member 33 is installed between the two connecting plates 311 and the telescopic end is connected to the rotating frame 34 .

[0045] Through the above arrangement, the bag clamp body 32 can be flexibly adjusted to adapt to packaging bags of different sizes, ensuring that the opening and fixing process of the packaging bags is more accurate.

[0046] In one embodiment, vertical guide columns 13 are provided at both transverse ends of the frame 1, and the two connecting plates 311 of the frame body 31 are respectively installed with guide column sliders 35 slidably connected to the longitudinal ends of the vertical guide columns 13. The sliders are made of wear-resistant nylon sliders, which provide low-friction and high-durability guiding effects, ensuring the stability of the bag clamp assembly 3 during the lifting process.

[0049] In one embodiment, the discharge port 11 extends downward from the frame 1 to form a hollow frame structure. Clamping assemblies 14 are provided on both longitudinal sides of the discharge port 11 to clamp the bag openings. The clamping assemblies 14 may include two relatively movable clamping plates (one of which is driven by a cylinder), or other clamping structures may be used, without limitation.

[0050] When the upper bag arm transports the packaging bag to the position of the lifting bag clamp mechanism, the lifting electric cylinder 41 descends, inserts the two bag clamp assemblies 3 into the packaging bag, and fine-tunes the distance between the two bag clamp bodies 32 through the telescopic member 33.
