[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figure 1 The diagram shows the structure of the mobile unpacking screw feeding system of this utility model. This explosion-proof mobile unpacking screw feeding system includes a conveying mechanism, an unpacking mechanism, and a feeding mechanism. The conveying mechanism includes a first support frame 11, a positioning frame 12, a driver (not shown in the diagram), and several conveying rollers 13. The driver drives the conveying rollers 13 to rotate, thereby conveying materials. The driver (e.g., a drive motor) and its transmission method are existing technologies. There can be multiple drivers, each driving the conveying rollers 13 individually or at intervals. Other driving methods are also possible, such as a drive gear connected to the output end of the drive motor, which meshes with a transmission chain to rotate the conveying rollers 13. These technical solutions are all existing technologies or can be directly obtained through common knowledge, and therefore will not be described in detail. Additionally, the positioning frame 12 is fixed to the upper end of the first support frame 11, and the conveying rollers 13 are located inside the positioning frame 12. Guardrails 14 are provided on the upper surface of the positioning frame 12 and on both sides of the conveying rollers 13. The guardrails 14 prevent materials from deviating from the conveying channel where the conveying rollers 13 are located.

[0024] Please continue reading. Figure 1 and Figure 2As shown, the unpacking mechanism of this utility model includes a second support frame 21, a shell 22, a folding door 23, a cutter, a pusher, and a storage compartment 24. The shell 22 is fixed on the second support frame 21 and has an inlet 27, an outlet 25, and a packaging bag outlet (not shown in the figure). The outlet 25 is located at the bottom of the shell 22 and has a filter screen 26, which can filter large particles of impurities in the material. The folding door 23 is located outside the inlet 27, and the upper edge of the folding door 23 is fixed to the outer wall of the shell 22 by a hinge. The shell 22 is also equipped with a pneumatic device. The telescopic end of the pneumatic device is connected to the outer side of the folding door 23 by a hinge. By activating the pneumatic device, the extension or retraction of its telescopic end can directly open and close the folding door 23. A sealing strip is provided between the folding door 23 and the inlet 27. In addition, the storage compartment 24 is fixed on the outer wall of the outer shell 22, wherein the packaging bag outlet and the inlet 27 are arranged opposite to each other, and the packaging bag outlet communicates with the storage compartment 24. Furthermore, the storage compartment 24 may be equipped with a cabinet door 241, which can be opened at any time to retrieve the outer packaging bags contained therein.

[0025] It should be noted that the conveying mechanism and the unpacking mechanism are connected. Specifically, the inner end of the positioning frame 12 of the conveying mechanism is connected to the outer shell 22 of the unpacking mechanism. Since the bottom of the first support frame 11 and the second support frame 21 is equipped with several casters 5, the conveying mechanism and the unpacking mechanism can move as a whole under the action of the casters 5, improving the flexibility of the entire feeding system. Additionally, as... Figure 2 and Figure 3 As shown, the cutter and pusher of this utility model are located inside the housing 22. The cutter is provided with an inclined plate 31 and a plurality of cutters 32 located on the inclined plate 31. The inclined plate 31 is fixed below the inner end of the feed port 27.

[0026] Please continue reading. Figure 3 As shown, the pusher of this utility model is provided with two mounting brackets 41. A threaded rod 42 and a limiting rod 43 are provided between the mounting brackets 41. A moving block 44 is also provided between the mounting brackets 41. The moving block 44 is provided with a limiting hole and a threaded hole. The threaded rod 42 passes through the threaded hole, and the limiting rod 43 is located in the limiting hole. One end of the threaded rod 42 is connected to a first servo motor 46. In other words, the output end of the first servo motor 46 is rotatably connected to one end of the threaded rod 42. Under the drive of the first servo motor 46, the moving block 44 can be displaced on the threaded rod 42. The moving block 44 is also provided with a push rod 45 perpendicular to the threaded rod 42 or the limiting rod 43. The push rod 45 is provided with several sharp parts 451.

[0027] In the operation of this mobile unpacking screw feeding system, the outer packaging bag containing materials is transported by the conveyor roller 13 and enters the outer casing 22 through the feed inlet 27. Under the inertia of the conveyor roller 13, the bag slides directly into the outer casing 22. During the slide, the packaging bag comes into contact with the inclined plate 31. As it slides, the cutter 32 on the inclined plate 31 cuts and slits the packaging bag, and the material inside the bag enters the feeding mechanism below through the discharge outlet 25. The feeding mechanism of this invention is connected to the discharge outlet 25. Specifically, the feeding mechanism can be a screw feeder, which transports the material through the rotation of the screw blades. The material inside the mechanism enters the spiral blades through the discharge port 25. After the material is spread, the outer packaging bag is still placed above the filter screen 26. At this time, the pusher starts to work. The original state of the pusher is that the moving block 44 and the push rod 45 are located at the end near the feed port 27. As the moving block 44 moves towards the collection bin 24, the push rod 45 also moves. At this time, the sharp part 451 on the push rod 45 can penetrate into the outer packaging bag until it moves to the packaging bag outlet. The outer packaging bag can be put into the collection bin 24 for recycling. The above movement process can also be set to a reciprocating motion, which can completely shake off and spill the material in the packaging bag to prevent material waste.

[0028] In other embodiments of this invention, an observation window 221 and a built-in glove 222 may be provided on the outer casing 22. When components inside the outer casing 22 malfunction, or in extreme cases, when the outer packaging bag is still left in a corner of the outer casing 22 and cannot be recycled, workers can perform the above-mentioned operations through the built-in glove 222. The condition inside the outer casing 22 can be observed at any time through the observation window 221. Furthermore, in a preferred embodiment, such as... Figure 3 As shown, the pusher is also equipped with a second servo motor 47. The end of the push rod 45 near the threaded rod 42 is rotatably connected to the output end of the second servo motor 47. Specifically, a through hole can be provided on the moving block 44 in a direction perpendicular to the threaded hole or the limiting hole. The push rod 45 is located in the through hole, so that the push rod 45 can be driven to rotate by the second servo motor 47. When the push rod 45 rotates upward, the sharp part 451 on the push rod 45 can stably hook the outer packaging bag. When the moving block 44 moves to the other end, the push rod 45 is rotated in the opposite direction, and the outer packaging bag can fall off the sharp part 451 and then fall into the storage compartment 24.

[0029] Through the above technical solution, the beneficial effects of the mobile unpacking spiral feeding system of this utility model include: the inlet of the outer shell 22 of the unpacking mechanism of this utility model is closed and has an explosion-proof function. At the same time, the pusher inside the outer shell 22 can push the unpacked outer packaging bag into the storage bin 24 to prevent the outer packaging bag from accumulating inside the outer shell 22. In addition, the pusher of this utility model can also move the outer packaging bag repeatedly, making the unloading more thorough during the movement.

[0030] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
