[0026] The conveying mechanism 6 includes a first rotating shaft 61, a second rotating shaft 62, a motor 63 and a conveying belt 64. Both ends of the first rotating shaft 61 and the second rotating shaft 62 are rotatably connected to the inner wall of the base 1. The second rotating shaft 62 is arranged on one side of the first rotating shaft 61. The motor 63 is fixedly connected to one end of the base 1. The output end of the motor 63 passes through the base 1 and is rotatably connected thereto. The output end of the motor 63 is fixedly connected to one end of the first rotating shaft 61. Both ends of the conveying belt 64 are sleeved on the first rotating shaft 61 and the second rotating shaft 62.

[0027] Through the above technical solution, by setting up the conveying mechanism 6 and starting the motor 63 to drive the first rotating shaft 61 to rotate, the conveyor belt 64 can be rotated to convey the printed paper packaging bags, so that the printed paper packaging bags can be moved to the bottom of the fixed frame 2.

[0028] Specifically, the guide mechanism 7 includes a guide plate 71, a threaded rod 72, a bearing seat 73 and a handle 74. The guide plate 71 is slidably connected to the conveyor belt 64. The threaded rod 72 is arranged at one end of one side of the guide plate 71. One end of the threaded rod 72 passes through the base 1 and is threadedly connected thereto. The bearing seat 73 is fixedly connected to the other end of the threaded rod 72. The other end of the bearing seat 73 is fixedly connected to one end of one side of the guide plate 71. The handle 74 is arranged on one side of the base 1, and the handle 74 is fixedly connected to one end of the threaded rod 72.

[0029] Through the above technical solution, by setting up the guide mechanism 7, according to the size of the printed paper outer packaging, by turning the handle 74 to drive the threaded rod 72 to rotate, the guide plate 71 can be moved to adjust the distance between the guide plates 71 on the conveyor belt 64, so that the printed paper packaging bag can be guided and positioned when it moves.

[0030] Specifically, sliding rods 11 are provided on both sides of the lower part of the tool holder 4, and the sliding rods 11 are provided on both sides of the dividing knife 5. One end of the sliding rod 11 passes through the tool holder 4 and is slidably connected thereto, and the other end of the sliding rod 11 is fixedly connected to a pressure plate 12, and a pressure plate spring 13 is provided between the tool holder 4 and the pressure plate 12. The pressure plate spring 13 is sleeved on the sliding rod 11 and is movably connected thereto, and the other end of the sliding rod 11 is fixedly connected to a fixed block 14.

[0031] Through the above technical solution, by setting the sliding rod 11 and the pressing plate 12, when the cutting knife 5 cuts the printed paper package, the printed paper package can be pre-fixed first, so that the cutting knife 5 can cut the printed paper package conveniently.

[0032] Specifically, the other end of one side of the guide plate 71 is fixedly connected to the limiting rod 10 , and the other end of the limiting rod 10 passes through the base 1 and is slidably connected thereto.

[0033] Through the above technical solution, by setting the limiting rod 10, the guide plate 71 can be guided and limited when it moves, so that it will not have a large position deviation when moving, thereby increasing the stability of the guide plate 71 when moving.

[0034] Specifically, four flow guiding mechanisms 7 are provided, and the four flow guiding mechanisms 7 are evenly distributed on the two conveying mechanisms 6 , and one end of the flow guiding plate 71 on one conveying mechanism 6 is provided as a guide plate with an inclined angle.

[0035] Through the above technical scheme and the above settings, the conveying mechanism 6 can be guided and limited when conveying the printed paper, and one end of the guide plate 71 on the conveying mechanism 6 is set as a guide plate with an angle tilt. Since no guide plate is provided under the dividing knife 5, the guide plate with an angle tilt can be used to guide the printed paper packaging after dividing to prevent the printed paper from being retained here and affecting the operation of the device.

[0036] Specifically, the two conveying mechanisms 6 are configured to work synchronously, and the rotations of the two conveying mechanisms 6 are the same.

[0037] Through the above technical solution, through the above arrangement, since when the printed paper packages are divided, it is necessary to move the connection between the two printed paper packages to the bottom of the dividing knife 5, so one of the printed paper packages will be located on one conveyor belt 64, and the other printed paper package will be located on another conveyor belt 64, so the two conveying mechanisms 6 need to be operated or stopped at the same time, so as to facilitate the dividing knife 5 to divide the two printed paper packages.

[0038] Working principle: when in use, first according to the size of the printed paper outer packaging, by turning the handle 74 to drive the threaded rod 72 to rotate, the guide plate 71 can be moved to adjust the distance between the guide plates 71, and then the printed paper packaging bag is placed between the guide plates 71. When the printed paper packaging and the guide plates 71 are too tight, they can be slightly opened to prevent the guide plates 71 from clamping the printed paper packaging and diverting it, so that the printed paper packaging cannot move normally. After the debugging of the guide mechanism 7 is completed, the first rotating shaft 61 is driven to rotate by starting the motor 63, so that the conveyor belt 64 can rotate, and then the printed paper packaging bag is placed between the guide plates 71 on the conveyor belt 64. Then, under the action of the conveying mechanism 6, the printed paper packaging bag is driven to move, and the connection of the two printed paper packaging bags is connected. The joint moves to the bottom of the dividing knife 5, at which time the two conveying mechanisms 6 stop running, and then the hydraulic cylinder 3 is started to push the knife holder 4 to drive the dividing knife 5 to move downward. Since the position of the pressure plate 12 is lower than that of the dividing knife 5, the pressure plate 12 will contact the calico paper packaging bag to press it, and when the dividing knife 5 continues to divide downward, the sliding rod 11 will slide upward, and under the action of the pressure plate spring 13, a thrust can be formed to push the pressure plate 12 to continue to install the calico paper packaging bag. Therefore, it will not affect the dividing of the calico paper packaging bag by the dividing knife 5, and the calico paper packaging bag can be fixed by the pressure plate 12 to facilitate the dividing of the calico paper packaging bag by the dividing knife 5. When the dividing is completed, the conveying mechanism 6 is started again to transport the divided calico paper packaging bag away from the device.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
