[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] This embodiment provides a garbage bag breaking and separation device, such as Figures 1 to 12 As shown, it includes a bag breaking mechanism and a bag grabbing mechanism. The bag breaking mechanism includes a mounting frame 1, which is used to be mounted on the mouth of a trash can 22. The mounting frame 1 is provided with a delivery port 6, which is connected to the mouth of the trash can 22. Two trash trays 2 are installed at the delivery port 6, and both trash trays 2 can be telescopic. The fixed ends of the two trash trays 2 are respectively hinged on the two opposite inner walls of the delivery port 6 through hinge shafts 3, wherein the hinge shafts 3 are arranged horizontally, so that the two trash trays 2 can be turned up and down. There are saw teeth 4 on the telescopic ends of the two trash trays 2, and the saw teeth 4 on the telescopic ends of the two trash trays 2 at the maximum extension position can mesh with each other on their rotation path, that is, when the telescopic ends of the trash trays 2 are at the maximum extension position, during the up and down rotation of the two trash trays 2, the saw teeth 4 on the two trash trays 2 at a certain position can mesh with each other, completely covering the delivery port 6, just like a double-leaf door leaf. The side of the two garbage trays 2 facing away from the bottom of the garbage bin 22 with the intermeshing teeth 4 forms a garbage bag placement area, where the resident places the garbage bag and then proceeds with the subsequent bag breaking and garbage separation process. The bag grabbing mechanism includes a mechanical gripper 5 and a moving component for driving the mechanical gripper 5 to move in space. Driven by the moving component, the mechanical gripper 5 can move to the garbage bag placed in the garbage bag placement area, and the mechanical gripper 5 can open and close to clamp the garbage bag, and then cooperate with the bag breaking mechanism to break the bag.

[0032] Working principle:

[0033] First, the resident places the garbage bag in the garbage bag placement area formed by the saw teeth 4. Figure 8 Then, the telescopic ends of the two garbage trays 2 are partially extended and retracted at the same time, so that a certain gap is generated between the mutually meshing saw teeth 4, and the gap is required to ensure that the garbage bag does not fall into the garbage can 22. At the same time, under the action of the gravity of the internal garbage, the bottom part of the garbage bag will sink downward and be located in the gap generated between the saw teeth 4, reference Fig. 9 Then, the telescopic ends of the two garbage trays 2 are re-extended, and the two serrations 4 are re-engaged to clamp the sunken portion at the bottom of the garbage bag, reference Fig.10 Then, the mechanical gripper 5 is driven by the moving assembly to move to the garbage bag and clamp a certain part of the upper half of the garbage bag, refer to Fig.10 As shown; then, the two garbage trays 2 are turned down at the same time, and the saw teeth 4 that clamp the garbage bag will tear the bottom of the garbage bag. At the same time, the gap between the saw teeth 4 of the two garbage trays 2 gradually becomes larger to meet the smooth falling of the garbage, and then falls into the mouth of the garbage bin 22 from the delivery port 6, and then falls into the garbage bin 22 from the mouth of the garbage bin, refer to Fig.11 As shown; then, the mechanical gripper 5, driven by the moving component, leaves the garbage bin 22 and transports it to a place specifically for recycling garbage bags, such as placing a garbage bag recycling bin 23 next to the garbage bin 22, so that the garbage bags can be transported to the top of the garbage bag recycling bin 23, and then the mechanical gripper 5 opens, and the garbage naturally falls into the garbage bag recycling bin 23; finally, the garbage tray 2 and the saw teeth 4 return to their original positions, and the saw teeth 4 re-engage to form a garbage placement area.

[0034] In this embodiment, Figures 1 to 12 As shown, a start button can be installed on the mounting frame 1, and after the resident has finished the garbage, the start button can be pressed, and the whole device will automatically run. A sensing device can also be installed in the delivery port 6 to sense the presence or absence of garbage bags, such as infrared sensors or the like.

[0035] In this embodiment, Figures 1 to 12 As shown, a rotating assembly is provided on the mounting frame 1, and the rotating assembly is used to drive the hinge shaft 3 to rotate. The rotating assembly can adopt various assemblies that can drive the hinge shaft 3 to rotate, such as a drive motor with a gear set, a drive motor with a worm gear, or a single drive motor, etc.

[0036] Furthermore, this embodiment provides a specific form of a rotating assembly, such as Figures 1 to 12As shown, the rotating assembly includes a worm gear, a worm 8 of which is horizontally rotatably connected to the mounting frame 1, and a worm wheel 7 of which is coaxially fixed to the hinge shaft 3. By rotating the worm 8, the worm wheel 7 meshing with the worm 8 is driven to rotate, which in turn drives the hinge shaft 3 to rotate, thereby driving the garbage tray 2 to rotate up and down. The worm 8 can be driven by a motor.

[0037] Further, in this embodiment, Figures 1 to 12 As shown, each of the two hinged shafts 3 is fixedly connected to a worm wheel 7, each of the two worm wheels 7 is meshed with a worm 8, and the two worms 8 share a worm shaft 9, so that driving one worm shaft 9 can simultaneously drive two worms 8 and two worm wheels 7, achieving a synchronous driving effect.

[0038] In this embodiment, Figures 1 to 12 As shown, the garbage tray 2 includes a hinge plate and a sliding plate 12, and a sliding groove 13 and a driving assembly are provided on a side of the hinge plate facing the bottom of the garbage bin 22.

The driving assembly is used to drive the sliding plate 12 to slide in the sliding groove 13, and the saw teeth 4 are arranged at one end of the sliding plate 12 away from the hinge shaft 3. When the sliding plate 12 slides toward the hinge shaft 3, the saw teeth 4 on the sliding plate 12 retract inward, and when the sliding plate 12 slides in a direction away from the hinge shaft 3, the saw teeth 4 on the sliding plate 12 extend outward.

[0039] Further, in this embodiment, Figures 1 to 12 As shown, the hinged plate includes a first plate segment 10 and a second plate segment 11, and an obtuse angle is formed between the first plate segment 10 and the second plate segment 11.

The piston rod of the telescopic cylinder 14 is extended and retracted, and the sliding plate 12 can be driven to move through the positioning hole 16 and the positioning column 15 to achieve the extension and retraction of the sawtooth 4. The telescopic cylinder 14 can be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder.

[0041] In this embodiment, Figures 1 to 12 As shown, two protective plates 17 are provided on the delivery port 6, and the two protective plates 17 are used to cover the two hinge shafts 3 respectively to prevent dust and rain and to prevent garbage from falling on the hinge shafts 3 and being rolled in.

[0042] In this embodiment, Figures 1 to 12 As shown, the moving assembly includes a horizontal slide rail 18 and a reel 19. The horizontal slide rail 18 is located above the delivery port 6. The reel 19 is slidably connected to the horizontal slide rail 18. The reel 19 is provided with a reel rope 20 connected to the mechanical gripper 5. The reel 19 reels or releases the reel rope 20 to realize the vertical movement of the mechanical gripper 5.
