[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0026] like Figures 1 to 3As shown, a conveying and cutting device of a package unpacking machine includes a frame 1, on which a conveying mechanism and a cutting mechanism are provided. The conveying mechanism is a belt conveyor, including a conveying belt 10, an active roller 11, a driven roller 12 and a conveying motor 13. The active roller and the driven roller are respectively located at both ends of the conveying belt and are rotatably connected to a mounting seat 14 provided on the frame. One end of the active roller is connected to the conveying motor. In this embodiment, a sprocket chain transmission mechanism is adopted between the active roller and the conveying motor. The mounting seat at one end of the conveying mechanism is assembled and connected with a waist-shaped hole 15 provided on the frame, and is assembled and connected with bolts, which is convenient for disassembly and adjustment of the position of the corresponding mounting seat, thereby avoiding loosening of the conveying belt after long-term use. The cutting mechanism is located above the conveying mechanism. The cutting mechanism includes a cutting motor 2, an upper wheel group, a lower wheel group and a cutting line 3. The lower wheel group includes two support wheels 4 that are respectively located above both sides of the conveying mechanism and are rotatably connected to the frame. The two support wheels are located on the same horizontal plane and there is a gap between them and the conveying mechanism. The cutting line passes around the two support wheels and the upper wheel group in turn to form a closed cutting coil connected end to end. The upper wheel group includes a driving wheel 5 and a driven wheel 6. The driving wheel is connected to the cutting motor. In this embodiment, a sprocket chain transmission mechanism is used between the driving wheel and the cutting motor. The driving wheel, the driven wheel and the two support wheels are located on the same vertical plane, so that the cutting line forms a quadrilateral closed-loop structure. The outer peripheries of the driving wheel, the driven wheel and the two support wheels are provided with a groove matching the cutting line, and the cutting line is embedded in the groove. The conveying mechanism conveys the packaging bags containing materials, and the cutting motor drives the driving wheel to rotate. The driving wheel drives the lower wheel group to rotate synchronously through the closed circular cutting line. The cutting line cuts the packaging bag during rotation, thereby cutting the packaging bag into two complete parts, the upper and lower parts, which are convenient for quick removal and effectively replace the transmission cutting method. It avoids the situation where the packaging bag is cut into multiple irregular small pieces and mixed with the material. At the same time, the packaging bag after cutting is in a sheet structure, which can effectively avoid material residue and reduce material waste.

[0027] like Figure 2 and Figure 3 As shown, a guide assembly is further provided above the input end of the conveying mechanism to correct the position of the packaging bag during the conveying process to ensure the cutting quality. The guide assembly includes two V-shaped guide plates 7 distributed on both sides of the conveying mechanism, forming a trumpet-shaped structure with a width gradually decreasing along the conveying direction. The two guide plates are located between the two support wheels, and the cutting line between the two support wheels is located at the trumpet. A cutting groove 701 is provided on each guide plate, and the cutting line passes through the cutting groove. When the packaging bag passes through the trumpet, the cutting line cuts the packaging bag.

[0028] Combine Figure 4As shown, in order to further improve the stability of the cutting process and improve the cutting quality, a cutting line limiting assembly is provided on the side of each support wheel close to the other support wheel. The cutting line limiting assembly includes two limiting wheels 8. The two limiting wheels are located on both sides of the cutting line and are tangent to the cutting line. A support plate 9 is provided under the two limiting wheels. Each limiting wheel and support wheel is rotatably mounted on the support plate. A support frame is provided on the support plate. The limiting wheel and support wheel are rotatably connected to the corresponding support frame respectively. A gap is provided between the support plate and the conveying mechanism, and it is detachably connected to the frame. In this embodiment, a bolt assembly connection is adopted.

[0029] The working principle of this utility model is as follows:

[0030] like Figures 1 to 4 As shown, during use, a packaging bag containing material is placed horizontally on the belt conveyor, with the bag's opening facing the output or input end of the belt conveyor. The bag is then conveyed horizontally by the belt conveyor. Two guide plates 7 correct the bag's position during conveyance, allowing it to pass through the flared opening formed by the two guide plates 7. As the cutting motor 2 drives the cutting line 3 to perform a circular, continuous cutting motion along the driving wheel 5, the driven wheel 6, and the two support wheels 4, the cutting line 3 at the bottom cuts the bag, separating it into upper and lower parts, thereby achieving the purpose of unpacking. The cut bag is separated into two complete parts, making it easier to remove and improving product quality.

[0031] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
