[0030] In the description of the present utility model, unless otherwise specified, the orientation or state relationship indicated by terms such as "upper", "lower", "top", "bottom", "longitudinal", etc. is based on the orientation or state relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the referred mechanism or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0031] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meaning of the above terms in the present utility model can be understood according to specific situations.

[0032] As Figure 1 、 Figure 2 As shown in the figure, the present utility model provides a device for recovering waste materials of packaging bags, including an unpacking machine main body 1 and a feeding channel 2 connected to the unpacking machine main body 1. An inner conveyor belt 3 at the same horizontal plane as the feeding channel 2 is provided inside the unpacking machine main body 1. The material bag 9 is placed on the outer conveyor belt surface of the feeding channel 2 and transported into the unpacking machine main body 1. The end of the inner conveyor belt 3 is connected to a bag outlet channel 4. The end of the bag outlet channel 4 is successively connected to a waste bag channel 5 and a waste material recovery channel 6. The end of the waste material recovery channel 6 is connected to a collection hopper 7.

[0033] As Figure 3 、 Figure 6As shown in the figure, the bag outlet channel 4 includes a bag blocking swing arm 401 and a bag twisting slideway 402. The bag blocking swing arm 401 and the bag twisting slideway 402 adopt a strip-shaped grid structure. The bag blocking swing arm 401 is fixed to the top inner wall of the unpacking machine main body 1 through a support frame, which can prevent the material bag 9 from tilting and ensure that the material bag 9 smoothly enters the bag outlet channel 4. The bag twisting slideway 402 is a rounded corner bending structure with an inclined lower end. A plurality of bag twisting wheels 403 are provided at the bending part of the bag twisting slideway 402. The plurality of bag twisting wheels 403 are arranged coaxially and parallelly. The edge of the bag twisting wheel 403 extends out from the grid gap of the bag twisting slideway 402 and is placed between the bag twisting slideway 402 and the end of the inner conveyor belt 3, facilitating full kneading of the material bag 9 when it passes through. The connecting shaft of the bag twisting wheel 403 is arranged parallel to the rotating shaft of the inner conveyor belt 3 to ensure that the material bag 9 passes through smoothly and reduce jamming, thereby reducing the probability of mechanical damage.

[0034] As Figure 4 , Figure 5 shown in the figure, the residual bag channel 5 includes a bag outlet auger 501 arranged at the center of its interior and a bag outlet motor 502 that provides power for the bag outlet auger 501. The spiral gap of the bag outlet auger 501 is half of the existing spiral gap. By increasing the spiral density, the residence time of the unpacked material bag 9 in the residual bag channel 5 is increased. The residual material recovery channel 6 includes a residual material recovery auger 601 arranged at the center of its interior and a residual material recovery motor 602 that provides power for the residual material recovery auger 601. A connecting channel is provided between the residual bag channel 5 and the residual material recovery channel 6. A residual material dropping port 503 is provided at the end of the residual bag channel 5, and a residual material recovery groove 603 is provided on the residual material recovery channel 6. The end face sizes of the residual material dropping port 503 and the residual material recovery groove 603 are the same and are fixedly connected to form the connecting channel. The residual material recovery channel 6 communicates with the collection hopper 7. The residual material recovery auger 601 rotates to transfer the material entering the residual material recovery channel 6 through the residual material recovery groove 603 to the collection hopper 7, reducing residual material waste. A cross brace 604 fixedly connected to the outer shell of the unpacking machine main body 1 is provided below the residual material recovery channel 6, and the residual material recovery motor 602 is fixedly installed at the other end of the cross brace 604. The cross brace 604 can improve the installation stability of the residual material recovery motor 602 and ensure the stable operation of the residual material recovery auger 601.

[0035] As Figure 6 shown in the figure, the lower end of the bag twisting slideway 402 is just placed at the top opening of the residual bag channel 5. A material baffle 504 is provided at the opening where the residual bag channel 5 is connected to the bag outlet channel 4. The material baffle 504 is inclined in the opposite direction of material transportation. When the unpacked material bag 9 enters the residual bag channel 5 after being twisted, the material baffle 504 can intercept the splashed material and make it enter the residual bag channel 5, reducing material waste.

[0036] In addition, the bag discharging motor 502 and the residual material recovery motor 602 are both connected with speed reducers, and the speed reducers are respectively coaxially connected with the bag discharging auger 501 and the residual material recovery screw 601. By reducing the rotation speeds of the bag discharging auger 501 and the residual material recovery screw 601, the residence time of the material bag 9 in the equipment is further increased, which helps to improve the discharge of the material in the residual bag and thus improve the discharging rate.

[0037] As Figures 1 - 3 , Figure 6 shown, a dust removal unit 8 is provided at the top of the unpacking machine main body 1. The dust removal unit 8 is placed above the bag discharging channel 4. The dust removal unit 8 includes a blower 801 and a plurality of filter rods 802. The blower 801 is placed outside the unpacking machine main body 1 for convenient air blowing. After the plurality of filter rods 802 are fixed, they extend into the unpacking machine main body 1 to more effectively remove and recycle environmental dust and reduce the dust content during the use of the equipment.

[0038] When the present utility model is in use, the material bag 9 is placed on the outer conveyor belt surface of the feeding channel 2 manually, by a gantry crane or a forklift. The outer conveyor belt transports the material bag 9 into the unpacking machine main body 1, and the inner conveyor belt 3 continues to transport the material bag 9 forward. After passing through the cutter (not labeled in the figure), the unpacking of the material bag 9 is completed. The unpacked material bag 9 passes through the bag discharging channel 4. The edges of a plurality of bag twisting wheels 403 extend out from the grid gaps of the bag twisting slideway 402 and are placed between the bag twisting slideway 402 and the end of the inner conveyor belt 3 to fully twist the material bag 9. Then it enters the residual bag channel 5 along the bag twisting slideway 402. The bag discharging motor 502 drives the residual bag discharging auger 501 to rotate. After the material bag 9 rotates sufficiently in the residual bag channel 5, it is pushed out. The material in the material bag 9 is discharged and falls into the residual material recovery channel 6 through the connection channel formed by the residual material falling port 503 and the residual material recovery tank 603. The residual material recovery motor 602 drives the residual material recovery screw 601 to rotate, and the residual material is rotated and transferred to the collection hopper 7, thereby improving the discharging rate.

[0039] The above has described the present utility model in detail through embodiments, but the above content is only the preferred embodiment of the present utility model and cannot be considered as limiting the implementation scope of the present utility model. All equivalent changes and improvements made according to the application scope of the present utility model shall still fall within the patent coverage scope of the present utility model.
