The sliding power component 216 is a rodless cylinder 211, mounted on the connecting plate at the telescopic end of the lifting power component 215. The moving end of the rodless cylinder 211 is connected to a slider 2161, which is connected to a mounting plate 220. The cutter 218 is movably mounted on the mounting plate 220. Specifically, a groove for the cutter 218 to mate with the cutting blade can be provided on the mounting plate 220, or a slide rail can be provided. The cutting blade 218 moves along the slide rail, the specific movement depending on the actual situation. The telescopic power component 217 is a slide cylinder, which pushes the cutting blade 218 to move on the mounting plate 220, so that the cutting blade 218 extends or retracts.

[0059] In one specific embodiment, the bag-carrying device 3 includes: a lifting module 301, which is installed on the mobile device 2;

[0060] The tensioning component is installed on the lifting module 301 and is driven to lift by the lifting module 301; the tensioning component is used to tension the outer packaging.

[0061] like Figure 5 As shown, the lifting module 301 includes a servo motor 311, which is connected to the tensioning component through a transmission component and drives the tensioning component to lift as a whole.

[0065] When using the bag-cutting device provided in this specific embodiment, for example when the outer packaging is a bag, when the detection sensor located on the drive mounting plate 305 or support plate 302 senses the bag opening, the bag stops moving. The tensioning drive component 304 drives the tensioning plate 303 to move downward. The tensioning plate 303 and the support plate 302 cooperate to tighten the bag opening. The servo motor 311 in the lifting module 301 moves, driving the tensioning component to rise, thereby driving the bag to rise to a suitable height. At the same time, the rodless cylinder 211 of the moving device 2 drives the truss 205 to move to the designated hopper. At this time, the bag is still in a tensioned state. The slide cylinder in the cutter assembly 200 drives the cutter 218 to extend. The sliding force component 216 drives the extended cutter 218 to move, completing the bag cutting.
