[0002] In the process of implementing the utility model, the inventor found that the prior art has at least the following problems:

[0003] In traditional paper bag machines, a pushing mechanism is required to push the paper bags to be transported. When processing paper bags of different sizes, a single pushing mechanism cannot meet the needs of paper bags of different sizes. Multiple pushing mechanisms are required to process large-sized paper bags. However, when multiple pushing mechanisms push small-sized paper bags, the multiple pushing mechanisms are far apart and cannot get close to each other, and cannot push extremely small-sized paper bags. When a single pushing mechanism pushes a large-sized paper bag, due to the large mass of the large-sized paper bag, it is easy to squeeze and deform the contact point between the paper bag and the pushing mechanism.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 3 , a chain push mechanism for a paper bag machine, comprising:

[0027] A frame 1, on which paper bags can be transported; a through slot 2, which is arranged on the frame 1; a pushing chain 3, which is rotatably mounted on the frame 1; a pushing mechanism 7, which is mounted on the pushing chain 3, and which can move in the through slot 2; by moving the pushing chain 3 in the through slot 2, the pushing mechanism 7 mounted on the pushing chain 3 pushes the paper bag, thereby achieving the purpose of pushing the paper bag to move. A push plate 8, which is detachably connected to the pushing mechanism 7; through the detachable connection between the push plate 8 and the pushing mechanism 7, when processing small-sized paper bags, the push plate 8 is removed, and the paper bag is pushed by the small-sized pushing mechanism 7; when processing large-sized paper bags, the push plate 8 is mounted on the pushing mechanism 7 to increase the pushing area, which is suitable for the use of large-sized paper bags. One structure can meet the transportation requirements of small-sized paper bags and large-sized paper bags at the same time, with a simple structure and high working reliability.

[0028] The driving mechanism can drive the pushing chain 3 to move, and the driving mechanism provides power for the pushing chain 3.

[0029] A through slot 2 is provided on the frame 1, and the through slot 2 is located near the middle of the frame 1, and the push chain 3 corresponds to the position of the through slot 2. Only one through slot 2 and one push chain 3 are provided on the frame 1, which can meet the conveying requirements of small-sized paper bags and large-sized paper bags at the same time, with a simple structure and high working reliability. The through slot 2 and the push chain 3 are located near the middle of the frame 1, and the push is more stable and reliable.

[0030] The pushing mechanism 7 includes a first mounting block 71, a second mounting block 72, a connecting rod 73 and a push block 74. The first mounting block 71 and the second mounting block 72 are fixedly mounted on the pushing chain 3; the first end of the push block 74 is hinged to the second mounting block 72; the first end of the connecting rod 73 is hinged to the first mounting block 71, and the second end of the connecting rod 73 is hinged to the push block 74. The first mounting block 71 and the second mounting block 72 provide mounting points for the push block 74. The hinge of the connecting rod 73, the first mounting block 71, the second mounting block 72 and the push block 74 makes the entire pushing mechanism 7 a movable connection. When the pushing mechanism 7 moves to the two ends of the pushing chain 3, the adjacent parts of the pushing mechanism 7 can move relative to each other. Because when the pushing chain 3 moves to the two ends, the adjacent distance will change. If a fixed connection is adopted, a jamming problem will occur.

[0031] The push plate 8 is detachably connected to the push block 74, and the width of the push plate 8 is greater than that of the push block 74. When processing small-sized paper bags, the push plate 8 is removed and the paper bags are pushed by the small-sized pushing mechanism 7; when processing large-sized paper bags, the push plate 8 is installed on the pushing mechanism 7 to increase the pushing area, which is suitable for the use of large-sized paper bags. One structure can meet the transportation needs of small-sized paper bags and large-sized paper bags at the same time, with a simple structure and high working reliability.

[0032] The pushing block 74 is perpendicular to the pushing chain 3, and can maintain vertical pushing during the pushing process, thereby achieving a better effect of pushing the paper bag.

[0033] The driving mechanism includes a driving shaft 5 and a driven shaft; the driving shaft 5 and the driven shaft are rotatably mounted on the frame 1, and a driving sprocket 4 and a driven sprocket are respectively provided on the driving shaft 5 and the driven shaft; the driving chain 3 is adapted to the driving sprocket 4 and the driven sprocket; and a driving motor 6 is also provided to drive the driving shaft 5 to rotate. The driving motor 6 drives the driving shaft 5 to rotate, and the driving shaft 5 drives the driving sprocket 4, thereby driving the driving sprocket to move, so as to achieve the purpose of pushing the paper bag.

[0034] The width of the through slot 2 is greater than the width of the push plate 8 , so that the push plate 8 can move smoothly in the through slot 2 .

[0035] A series of pushing mechanisms 7 are evenly arranged on the length square of the pushing chain 3, which can push multiple paper bags to meet the needs of mass production.

[0036] The width of the push plate 8 is greater than the width of the push block 74. When processing small-sized paper bags, the push plate 8 is removed and the paper bags are pushed by the small-sized pushing mechanism 7; when processing large-sized paper bags, the push plate 8 is installed on the pushing mechanism 7 to increase the pushing area, which is suitable for the use of large-sized paper bags. One structure can meet the transportation needs of small-sized paper bags and large-sized paper bags at the same time, with a simple structure and high working reliability.

[0037] After adopting the above structure, the transportation requirements of small-sized paper bags and large-sized paper bags can be met at the same time, the structure is simple, and the working reliability is high.
