[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1 to 7 The embodiment of the present invention preferably provides a bag sorting and discharging mechanism, including a body base 1, on which a turntable structure 2 for conveying material bags is provided; on the turntable structure 2, a plurality of hopper racks 3 for accommodating multiple material bags are provided; on the body base 1, a frame 4 is also provided; and a bag sorting system for neatly arranging multiple material bags is also provided. The turntable structure can convey material bags by rotation, and the material bags are placed on the hopper rack on the turntable structure. Multiple bags can be placed at a time, and the number of bags depends on the number of boxes to be packed. The bag sorting system can be used to straighten the multiple material bags on the hopper rack before discharging, so as to meet the requirements of uniform boxing, so that all bags can fall into the packaging box when discharging, reducing the occurrence of boxing failures due to misalignment.

[0030] The bag sorting system includes a pressing structure 5 provided on the frame 4 and capable of stabilizing the multiple material bags in the hopper rack 3, an opening and closing structure 6 provided in the hopper rack 3 and capable of shrinking or expanding the space therein to align the two opposite sides of the material bags, and a pushing structure 7 provided on the frame 4 and capable of aligning the other two opposite sides of the material bags on the hopper rack 3 and then pushing out the material. The pressing structure is capable of pressing the multiple material bags from the top to the bottom during operation. It is worth noting that the pressing structure is only used to stabilize the material bags from the top and does not hold them tightly. The material bags are still in a movable state on the front, back, left, and right sides, allowing the opening and closing structure to align the material bags during this period. The entire alignment process is specifically as follows: after the pressing structure stabilizes the material bags, the opening and closing structure is activated, and the multiple stabilized material bags are pushed to the left and right sides by aligning their edges, thereby aligning the materials. In this state, the pushing mechanism is activated to push out the material bags on the hopper rack, aligning the front and back sides of the bags during the pushing process. After pushing out, the aligned and flattened bags can be subsequently transported into packaging boxes, completing the alignment and packing of the entire set of material bags. The packaging boxes can be packed using intermittent transmission in conjunction with the pushing mechanism, using existing packaging box conveying devices. All electrical equipment in this technical solution can be externally connected to a control center to adjust parameters such as speed, position, and feed depth.

[0031] The turntable structure 2 described in the present invention includes a fixed disk 21 fixed on the fuselage base 1, a rotating disk 22 that can rotate at a fixed point is concentrically arranged inside the fixed disk 21, a servo motor 23 is provided at the bottom center of the fixed disk 21, the center of the rotating disk 22 is fixed on the movable end of the servo motor 23, and an arc-shaped guide rail 24 that can prevent the material bags from falling on the hopper rack 3 is fixed on one side above the fixed disk 21. The fixed disk is a fixed and immovable circular disk, and the rotating disk is rotatably arranged in the middle of it. The servo motor in the center of the fixed disk drives the rotating disk so that the rotating disk can rotate and transmit multiple material bags by rotating the moving disk. The function of the arc-shaped guide rail is to allow the hopper rack to pass through the arc-shaped guide rail during the rotation of the rotating disk. The limiting function of the arc-shaped guide rail can prevent the multiple material bags in the hopper rack from being scattered due to the inertia force of the rotating disk.

[0032] The curved guide rail 24 of the present invention comprises a feed end 241 and a discharge end 242, respectively. The curved outer edge of the curved guide rail 24 is aligned with the outer edge of the fixed plate 21. The feed end is the end where the hopper frame enters. The material bags in the hopper frame are loaded by connecting to an external device, which can be conventional loading equipment in the prior art. After loading, the material enters the feed end. The discharge end is the end where the hopper frame exits the curved guide rail. After exiting, the material is sorted by a sorting system and discharged. The material can be discharged by connecting to an external device, which can be conventional loading equipment in the prior art.

[0033] In the present invention, several hopper racks 3 are concave and arranged in a circular array outside the surface of the rotating disk 22. Each hopper rack moves with the rotating disk, and achieves uninterrupted operation by continuously loading and unloading materials. The hopper rack is provided with an opening and closing structure that can narrow or expand the internal space of the hopper rack to arrange the material bags flat.

[0034] The opening and closing structure 6 in the present invention includes a dynamic vertical plate 61 and a fixed vertical plate 62 for forming the hopper frame 3, as well as a movable plate 63 fixedly arranged at the bottom of the dynamic vertical plate 61, and a guide groove plate 64 arranged at the bottom of the fixed vertical plate 62 for accommodating the limited movement of the movable plate 63. The guide groove plate 64 can be connected to the rotating disk 22 by screws. The opening and closing structure 6 also includes a through groove 65 arranged at the bottom of the rotating disk 22 and corresponding to the position of the hopper frame 3. A connecting plate 66 is fixedly arranged at the bottom of the movable plate 63 and is limited in movement within the through groove 65. An electric push rod 67 is fixed to the bottom of the rotating disk 22 on one side of the connecting plate 66. The fixed vertical plate is fixed to the rotating disk, while the dynamic vertical plate can move parallel to the fixed vertical plate. The specific working steps are as follows: by pushing or pulling the connecting plate by the electric push rod, the connecting plate will drive the movable plate, and the movable plate will drive the dynamic vertical plate to move, thereby realizing movement relative to the fixed vertical plate. The guide groove plate and the movable plate are arranged to limit the movement of the movable vertical plate, and the through groove is used for the connecting plate to be arranged therein and limit its movement.

[0035] In the present invention, the frame 4 is topped with a columnar slide rail 41. A slider 42, capable of linear sliding, is positioned at the upper limit of the columnar slide rail 41. The push mechanism 7 is positioned at the bottom of the slider 42. The columnar slide rail and the slider mounted thereon are used to adjust the initial position of the push mechanism. This can be controlled by connecting the columnar slide rail to an external control center. The position of the press-fit structure on the push mechanism will also move accordingly.

[0036] The pushing mechanism 7 in the present invention includes a second electric push rod 71 disposed at the bottom of the slider 42. A push plate 72 is fixed to the movable end of the second electric push rod 71. A limit chain 73 is connected to one side of the push plate 72 and the second electric push rod 71. By activating the second electric push rod, the push plate can push the material bag in the hopper rack out for unloading. Since the second electric push rod is disposed at the bottom of the slider, the column slide drives the slider to adjust the activation position of the second electric push rod.

[0037] The pressing mechanism 5 of the present invention comprises a third electric push rod 51 positioned above a push plate 72. A pressure plate 52 is fixed to the movable end of the third electric push rod 51, located at the bottom. The pressure plate is used to stabilize and flatten the multiple material bags within the hopper rack, preventing individual bags from stacking at an angle. After the column-type slide rail adjusts the push plate's starting position, the push plate is positioned to one side of the hopper rack, while the pressure plate is positioned above the hopper rack.

[0038] In the present invention, grooves 8 are provided on the movable upright plate 61, the fixed upright plate 62, the movable plate 63, and the guide groove plate 64. A protrusion 81 that can move within the groove 8 is provided on the outer peripheral edge of the lower section of the push plate 72. The cooperation between the groove and the protrusion allows the push plate to remain upright during movement. The protrusions can also reduce the possibility of missing a push due to the bag passing through the bottom gap when pushing flat material bags.
