[0043] like Figure 1-12As shown, the embodiment of the present application discloses an automatic collection and bundling device for packaging bags, including a frame feeding mechanism 10, a compression mechanism 20, and an output mechanism 30 arranged in sequence; the frame feeding mechanism 10 includes a pushing mechanism 60 and a frame storage mechanism 70, the frame storage mechanism 70 is used to store a bundling frame 80, and the pushing mechanism 60 is used to push the bundling frame 80 in the frame storage mechanism 70 into the compression mechanism 20; the compression mechanism 20 includes a cabinet 21, the cabinet 21 is provided with an upper door leaf 22, a lower door leaf 23 and an opening and closing mechanism 50 for driving the upper door leaf 22 and the lower door leaf 23 to open and close, the cabinet 21 is provided with a pressing mechanism 40 and a pushing mechanism 26, the pressing mechanism 40 is used to compact the packaging bags in the cabinet 21, and the pushing mechanism 26 is used to push the compacted and bundled packaging bags out of the cabinet 21.

[0044] Specifically, the upper door leaf 22 and the lower door leaf 23 are arranged up and down at the front side of the cabinet 21, and the upper door leaf 22 and the lower door leaf 23 are respectively controlled by two opening and closing mechanisms 50 arranged on the sides of the cabinet 21. The upper door leaf 22 and the lower door leaf 23 are used to control the opening or closing of the cabinet 21. When the upper door leaf 22 is opened, it can be used to place packaging bags into the cabinet 21, and when the lower door leaf 23 is opened, it can be used to push out the bundled packaging bags. During the compression and bundling process, the upper door leaf 22 and the lower door leaf 23 are both in a closed state to ensure the closure of the cabinet 21, thereby ensuring safety in the working state. The opening and closing mechanism 50 includes a plurality of hinge seats 51 arranged vertically at intervals on the side of the cabinet 21 and an opening and closing cylinder 55 arranged on the side of the cabinet 21. A vertically arranged hinge shaft 52 is arranged on the hinge seat 51. A hinge plate 53 is hingedly arranged on the hinge shaft 52. One end of the hinge plate 53 away from the hinge shaft 52 is fixedly connected to the upper door leaf 22 or the lower door leaf 23. In this embodiment, one opening and closing mechanism 50 is provided with three hinge seats 51, which are arranged at the upper, middle and lower positions corresponding to the height of the upper door leaf 22 or the lower door leaf 23, respectively. The middle hinge plate 53 is located at one end of the hinge shaft 52 and is provided with a hinge block 54 in the direction away from the upper door leaf 22 or the lower door leaf 23. The cylinder end of the opening and closing cylinder 55 is hinged to the side of the cabinet 21, and the piston rod end is hinged to the hinge block 54. The opening and closing cylinder 55 performs telescopic movement to pull the middle hinge plate 53 to rotate around the hinge shaft 52, thereby driving the upper door leaf 22 or the lower door leaf 23 to rotate around the hinge shaft 52 to open or close. Setting three hinge seats 51 and setting a hinge block 54 in the middle to connect the opening and closing cylinder 55 can effectively ensure force balance and make it easier to open or close the door leaf.

[0045] The pressing mechanism 40 is arranged on the top of the cabinet 21, and includes a hydraulic cylinder 41 arranged on the top plate of the cabinet 21. The hydraulic rod of the hydraulic cylinder 41 passes through the top plate downward and a pressing plate 42 is arranged at the end. The hydraulic cylinder 41 drives the pressing plate 42 to move downward to compact the packaging bag, which can provide sufficient downward force for the pressing plate 42 to ensure that the packaging bag is compacted. In order to further ensure the stability of the pressing movement of the pressing plate 42, a plurality of first guide columns 43 are extended upward on the upper plate surface of the pressing plate 42, and a plurality of guide sleeve holes are arranged on the top plate of the cabinet 21 corresponding to the first guide columns 43. The first guide columns 43 and the guide sleeve holes form a limiting guide to limit the lifting and lowering movement of the pressing plate 42, so as to ensure that the pressing plate 42 will not deviate during movement.

[0046] The push-out mechanism 26 is arranged on the rear plate of the cabinet 21, and includes a push-out cylinder 261 arranged on the lower side of the rear plate of the cabinet 21. The piston rod of the push-out cylinder 261 penetrates into the cabinet 21 and is provided with a push-out plate 262 at the end. The push-out plate 262 is located in the area corresponding to the lower door leaf 23. After the packaging bags in the cabinet 21 are bundled, the lower door leaf 23 is opened, and the piston rod of the push-out cylinder 261 pushes the push-out plate 262 to move in the direction of the lower door leaf 23, so as to push out the packaging bags in the cabinet 21. In order to ensure the stability of the movement of the push-out plate 262, a plurality of second guide rods 263 are provided on the rear side plate of the push-out plate 262 to extend outside the cabinet 21, and a plurality of guide sleeve holes are provided on the rear plate of the cabinet 21 corresponding to the second guide rods 263. The movement of the push-out plate 262 is limitedly guided by the second guide rods 263 and the guide sleeve holes to form a limit guide, so as to ensure that the push-out plate 262 will not deviate from the direction when pushing out the packaging bags, thereby ensuring that the packaging bags will not tilt when being pushed out of the cabinet 21.

[0047] To cooperate with the movement of the frame feeding mechanism 10, two vertically arranged long holes 24 are spaced apart on the rear plate of the cabinet body 21 and the lower door leaf 23, two grooves 25 connected to the front and rear long holes 24 are opened on the bottom plate of the cabinet body 21, and a plurality of through grooves 44 are opened on the lower plate surface of the lower pressure plate 42 corresponding to the grooves 25 on the bottom plate.

[0048] In the specific configuration, the bundling frame 80 includes a C-shaped frame 81 and a connecting rod 82. A fixed shaft 83 perpendicular to the C-shaped frame 81 is provided at the upper end of the C-shaped frame 81, and one end of the connecting rod 82 is hinged to the fixed shaft 83 through a connecting block 85. The lower side edge of the upper end of the C-shaped frame 81 is arranged in an arc shape, so that the connecting rod 82 can avoid when rotating around the fixed shaft 83. A torsion spring 84 is arranged on the fixed shaft 83, and the torsion spring 84 provides an upward force for the connecting rod 82. The upper side edge of the upper end of the C-shaped frame 81 is not arranged in an arc shape, so that the connecting rod 82 cannot continue to rotate after being collinear with the upper side of the C-shaped frame 81. That is, in the initial state, the connecting rod 82 is located at the upper end of the C-shaped frame 81 and is collinear with the frame rod at its upper end, so that it is convenient for the frame feeding mechanism 10 to feed the bundling frame 80 into the cabinet 21.

[0049] A locking block 86 is provided at the lower end of the C-shaped frame 81, and a plurality of ratchet teeth 861 are provided on the upper side of the locking block 86, and the outer side of the ratchet teeth 861 is an inclined surface and the inner side is a vertical surface. A locking mechanism 87 is provided at the end of the connecting rod 82 away from the connecting block 85 corresponding to the locking block 86, and the locking mechanism 87 includes a through hole 871 provided at the end of the connecting rod 82 away from the connecting block 85 and penetrating the rod body of the connecting rod 82, and the length direction of the through hole 871 is perpendicular to the fixed axis 83, and the through hole 871 is a square hole as a whole, and its inner hole profile is larger than the cross-sectional profile of the locking block 86, and the front end profile of the locking block 86 is slightly smaller than the rear end profile, and the lower side surface of the locking block 86 is an arc surface, so that when the connecting rod 82 rotates downward around the fixed axis 83, it can be ensured that the through hole 871 is just put on the locking block 86 and continues to move until the connecting rod 82 and the C-shaped frame 81 form a square shape. An inner hole 872 connected to the through hole 871 is provided in the connecting rod 82 along its length direction, a locking bolt 873 is slidably provided in the inner hole 872, a second compression spring 874 is provided between the upper end surface of the locking bolt 873 and the top surface of the inner hole 872, and the second compression spring 874 provides downward pressure for the locking bolt 873. The lower end of the locking bolt 873 is an inclined surface that cooperates with the ratchet 861, so that when the through hole 871 is sleeved on the locking block 86, the locking bolt 873 cooperates with the ratchet 861, and when the connecting rod 82 moves to the right position, the locking bolt 873 is pressed against the ratchet 861 of the locking block 86 under the pressure of the second compression spring 874, so that the connecting rod 82 cannot return to its original position under the action of the torsion spring 84. Furthermore, a strip groove 875 communicating with the inner hole 872 is provided inwardly on the outer side of the connecting rod 82 near the through hole 871, and a locking pin 876 is slidably provided in the strip groove 875, and the locking pin 876 is fixedly connected with the locking bolt 873. In this way, when it is necessary to open the bundling frame 80, the locking bolt 873 can be pulled out from the locking block 86 by manually sliding the locking pin 876 upward, and after the locking bolt 873 and the ratchet 861 lose the matching limit, the connecting rod 82 can return to its original position under the action of the torsion spring 84, thereby opening the bundling frame 80. In this way, the bundling frame 80 after opening is not damaged and can be recycled for further use, thereby improving the recycling rate of resources.

[0050] The push mechanism 60 is arranged in the middle of the rear side of the cabinet 21, and two storage frame mechanisms 70 are arranged on both sides of the push mechanism 60, and the storage frame mechanism 70 is used to store the bundling frame 80. Specifically, the storage frame mechanism 70 includes a storage frame 71, and the storage frame 71 as a whole includes a top plate, a bottom plate, and an inner side plate adjacent to the push mechanism 60. The top plate and the outer side of the bottom plate are connected by a connecting plate 73, and the distance between the top plate and the bottom plate is equal to the height of the bundling frame 80, so as to ensure that the bundling frame 80 will not move in the height direction after being placed. A top pressing frame 72 is arranged on the outer side of the storage frame 71 and located inside the connecting plate 73. A plurality of third guide columns 74 are arranged on the outer side of the top pressing frame 72 to extend outward, and the length of the third guide columns 74 is greater than the distance between the inner side plate and the connecting plate 73. A plurality of guide sleeve holes are provided on the connecting plate 73 corresponding to the third guide column 74. The third guide column 74 passes through the guide sleeve holes and a limiting circular plate 75 is provided at the end to prevent the third guide column 74 from falling off from the guide sleeve hole when the top pressure frame 72 moves to the innermost side. A first compression spring 76 is sleeved on the column body of the third guide column 74 located between the top pressure frame 72 and the connecting plate 73. One end of the first compression spring 76 abuts against the top pressure frame 72 and the other end abuts against the connecting plate 73. The first compression spring 76 can provide an inward pressing force for the top pressure frame 72, so that after the innermost bundling frame 80 is pushed away, the top pressure frame 72 will automatically press the remaining bundling frames 80 to move inward to fill the position, thereby realizing automatic frame loading. A baffle 78 is provided on the top plate and the bottom plate of the storage frame 71, which are both away from the cabinet 21 and extend toward the middle, to prevent the bundling frame 80 from moving in the horizontal direction. A vertically arranged arc-shaped guide plate 77 is provided on the top plate and the bottom plate of the storage frame 71 away from the cabinet 21 and adjacent to the outer side of the baffle plate 78.
