[0028] like Figures 1 to 4 As shown, the present application provides a bag-splitting mechanism for packaging bags 80, including a frame 10, a baffle 30, a bag-splitting assembly 40 and a conveying assembly 90. A workbench 10a is provided on the top surface of the frame 10, and two partitions 20 are axially symmetrically arranged on the workbench 10a, and a discharge space is formed between the two partitions 20; the baffle 30 is provided at the discharge end of the discharge space, and forms a gap with the surface of the workbench 10a for the packaging bags 80 to pass through, and the two ends of the baffle 30 are respectively connected to the inner walls on both sides of the frame 10; the bag-splitting assembly 40 is provided on the front side of the baffle 30, and is used to separate the packaging bags 80 stacked in the discharge space; the conveying assembly 90 is provided in the discharge space, and is used to convey the packaging bags 80 located at the bottom layer to the bag-splitting assembly 40.

[0029] In this embodiment, two partitions 20 are symmetrically arranged on the work surface to form a discharge space on the workbench 10a. The stacked packaging bags 80 are then placed into the discharge space. At this time, the packaging bags 80 located at the bottom layer contact the conveying assembly 90. The conveying assembly 90 then transports the packaging bags to the bag separation assembly 40, and the bag separation assembly 40 transports the materials forward. In this way, the materials stacked in the discharge space are alternately separated into bags, thereby achieving separation of the stacked packaging bags 80. The structure is simple and the degree of automation is high, which helps to reduce the labor intensity of workers and improve the efficiency and quality of bag separation. In addition, the baffle 30 is set to block the packaging bags 80 stacked in the discharge space, so that the packaging bags 80 located at the bottom layer only pass through the gap between the baffle 30 and the surface of the workbench 10a. The remaining packaging bags 80 are blocked by the baffle 30 and cannot be transported forward, thereby ensuring that the stacked packaging bags 80 can be separated into bags.

[0030] In one possible embodiment, the conveying assembly 90 includes a first rotating rod 91 and a second rotating rod 92 arranged side by side along the width direction of the workbench 10a, the first rotating rod 91 and the second rotating rod 92 are arranged below the workbench 10a, and the first rotating rod 91 is located at one end close to the bag dividing assembly 40, the first rotating rod 91 has a plurality of first conveying wheels 93 distributed along its axial direction, the first conveying wheel 93 at least partially passes through the workbench 10a and extends into the discharge space, the second rotating rod 92 has a plurality of second conveying wheels 94 distributed along its axial direction, the second conveying wheel 94 at least partially passes through the working bar and extends into the discharge space, and the first rotating rod 91 and the second rotating rod 92 are connected by a transmission belt 200. That is to say, after the stacked packaging bags 80 are placed into the discharge space, the packaging bags 80 located at the bottom layer are in contact with the first conveying wheel 93 and the second conveying wheel 94, and then the first rotating rod 91 is driven to rotate. Since the first rotating rod 91 and the second rotating rod 92 are connected by a transmission belt 200, the second rotating rod 92 can be driven to rotate, and then the first conveying wheel 93 and the second conveying wheel are operated to convey the stacked packaging bags 80 to the bagging assembly 40 in sequence and in an orderly manner, thereby realizing automatic bagging of the packaging bags 80 without manual bagging, which is beneficial to reducing labor intensity.

[0031] In one possible embodiment, the bag dividing assembly 40 includes a first transmission roller, a second rotating roller, a driving wheel and a roller. The first transmission roller is rotatably arranged below the workbench 10a. The driving wheel is arranged on the first transmission roller, and the driving wheel at least partially passes through the workbench 10a. A driven wheel is provided on the first rotating rod 91. A conveyor belt is connected between the driven wheel and the driving wheel, and the conveyor belt at least partially extends out of the workbench 10a. The second transmission roller is arranged above the workbench 10a and is located directly above the first transmission roller. The roller is sleeved on the second transmission roller, and the outer peripheral surface of the roller is in contact with the portion of the conveyor belt passing through the workbench 10a. In this way, when the stacked packaging bags 80 are placed into the discharge space, the front part of the packaging bag 80 at the bottom layer contacts the conveyor belt, and then the first transmission roller is driven to rotate, thereby driving the driving wheel to rotate, so that the conveyor belt is driven to run, and the packaging bag 80 at the bottom layer can be conveyed forward. In this way, the packaging bags 80 stacked in the discharge space are alternately separated without manual operation, which is beneficial to reducing the pulling strength and improving the efficiency of bag separation.

[0032] In one possible embodiment, the machine further includes a bow 70 and a first connecting rod 60. One end of the first connecting rod 60 is connected to the inner sidewall of the frame 10. The bow 70 is mounted around the outer periphery of the roller, and one end of the bow 70 is connected to the other end of the first connecting rod 60. The other end of the bow 70 is rotatably connected to a first roller, the outer periphery of which contacts the portion of the conveyor belt that extends beyond the workbench 10a. This facilitates the rotation of the first roller connected to the bow 70 to contact the upper surface of the packaging bag 80 entering the conveyor belt, ensuring that the packaging bag 80 does not deviate during forward conveyance of the bag on the web.

[0033] In a possible embodiment, it also includes a power assembly 100, which includes a power piece 101, a first synchronous wheel 102, a second synchronous wheel 104, a third synchronous wheel 106 and a transmission shaft 102. The power piece 101 is arranged below the workbench 10a, and the output end of the power piece 101 passes through the side wall of the frame 10 and is connected to the first synchronous wheel 102. The side wall of the frame 10 extends outward with a transmission shaft 102, and the second synchronous wheel 104 and the third synchronous belt are arranged side by side on the rotating shaft. The end of the first transmission roller passing through the side wall of the frame 10 is provided with a fourth synchronous wheel 107, a first synchronous belt 105 is connected between the first synchronous wheel 102 and the second synchronous wheel 104, and a second synchronous belt 108 is connected between the third synchronous wheel 106 and the fourth synchronous wheel 107. That is to say, after the packaging bags 80 are stacked in the discharge space, the power part 101 drives the first synchronous wheel 102 to rotate, and the first synchronous belt 105 is connected between the first synchronous wheel 102 and the second synchronous wheel 104, and the second synchronous wheel 104 and the third synchronous wheel 106 are both sleeved on the transmission shaft 102, which can drive the third synchronous wheel 106 to rotate. Since the third synchronous wheel 106 and the fourth synchronous wheel 107 are connected by the second synchronous belt 108, and the fourth synchronous wheel 107 is connected to the first transmission roller, the first transmission roller is driven to rotate, and then the conveyor belt is driven to operate, so that the packaging bags 80 on the bottom layer are transported forward, and the packaging bags 80 stacked in the discharge space are separated into bags.

[0034] In one possible embodiment, a pressing assembly 50 is further included, and the pressing assembly 50 includes a second connecting rod 51 and a second roller 52. The second connecting rod 51 is arranged at the discharge end of the bag-dividing assembly 40 along the width direction of the workbench 10a, and one end of the second connecting rod 51 is connected to the inner side wall of the frame 10. The second roller 52 is rotatably connected to the other end of the second connecting rod 51, and a through channel is formed between the outer peripheral surface of the second roller 52 and the surface of the workbench 10a. In other words, the packaging bag 80 separated from the bag-dividing assembly 40 is conveyed forward under the action of the conveyor belt, and then enters the through channel. At this time, the second roller 52 contacts the upper surface of the packaging bag 80 and rotates, thereby ensuring that the packaging bag 80 can be conveyed in a straight line during the conveying process, avoiding left and right deviations that lead to processing in subsequent steps.

[0035] In one possible embodiment, a first adjustment hole 10b is provided at the location where the workbench 10a connects to the partition 20. The first adjustment hole 10b extends along the width of the workbench 10a. A connecting edge extends outward from the outer surface of the partition 20, and a first mounting hole is provided on the connecting edge, which is compatible with the first adjustment hole 10b. This allows the partition 20 to be adjusted, and thus the size of the discharge space to accommodate the separation of packaging bags 80 of different sizes. Because the thickness of individual packaging bags 80 varies when different packaging bags 80 are separated, the gap between the baffle 30 and the surface of the workbench 10a needs to be adjusted to accommodate the continued separation of different packaging bags 80. To this end, in one possible embodiment, the baffle 30 is bent to form a connecting ear, which is provided with a second adjustment hole. The sidewall of the frame 10 is provided with a second mounting hole that is compatible with the second adjustment hole. That is to say, when adjusting the baffle 30, first take out the fasteners (such as bolts) inserted into the second adjustment hole and the second mounting hole, and then adjust the baffle 30 until the baffle 30 is adjusted to the desired position, and then reuse the fasteners to pass through the second adjustment hole and the second mounting hole to achieve the adjustment of the baffle 30. The structure is simple and the adjustment is convenient, and it can be applied to different packaging bags 80 for bagging.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
