[0022] The following further elaborates on the present utility model in detail in conjunction with the accompanying drawings and specific embodiments.

[0023] As Figures 1 to 3 shown, the side corner folding device of the tissue packaging machine in this embodiment includes a machine base 1, a conveyor belt 2, and a driving mechanism 3 for driving the conveyor belt 2 to rotate. Corner folding assemblies 4 are respectively arranged on both sides of the machine base 1. The corner folding assembly 4 includes a connecting base plate 401. Along the conveying direction of the conveyor belt 2, a first corner folding plate 402, a second corner folding plate 403, and a third corner folding plate 404 are sequentially arranged on the connecting base plate 401. A pressing and folding forming part 4021 and a first inclined surface 4022 are arranged on the first corner folding plate 402. A second inclined surface 4031 and a third inclined surface 4032 are arranged on the second corner folding plate 403. A fourth inclined surface 4041 is arranged on the third corner folding plate 404. A first corner folding groove 5 is formed between the first inclined surface 4022 and the second inclined surface 4031. A second corner folding groove 6 is formed between the third inclined surface 4032 and the fourth inclined surface 4041. By arranging the corner folding assemblies 4 on both sides of the conveyor belt 2, the packaging film can pass through the corner folding assemblies 4 along with the movement of the conveyor belt 2 and complete the side corner folding and covering. Only one set of action mechanisms is used, with good running stability and high reliability, which can effectively reduce costs and improve production efficiency. The corner folding assembly 4 includes a first corner folding plate 402, a second corner folding plate 403, and a third corner folding plate 404. A pressing and folding forming part 4021 is arranged at the input end of the first corner folding plate 402. At the same time, a first corner folding groove 5 is formed between the first corner folding plate 402 and the second corner folding plate 403, and a second corner folding groove 6 is formed between the second corner folding plate 403 and the third corner folding plate 404. The side of the packaging film is pressed and folded by the pressing and folding forming part 4021 to form an upper side corner fold and a lower side corner fold. The upper side corner fold and the lower side corner fold are covered through the first corner folding groove 5 and the second corner folding groove 6, which has the advantages of simple structure and good usability.

[0024] As Figure 2As shown, preferably, the first fold angle groove 5 extends obliquely upward along the conveying direction, and the second fold angle groove 6 extends obliquely downward along the conveying direction. In this embodiment, the first fold angle groove 5 is arranged obliquely upward from bottom to top, and the second fold angle groove 6 is arranged obliquely downward from top to bottom. Then, the lower side corner fold of the packaging film first accesses the first fold angle groove 5 and gradually folds inward as the conveyor belt 2 moves. Then, the upper side corner fold of the packaging film accesses the second fold angle groove 6 and gradually folds inward as the conveyor belt 2 moves, so that the upper side corner fold wraps the lower side corner fold. In other embodiments, the first fold angle groove 5 can be arranged obliquely downward from top to bottom, and the second fold angle groove 6 can be arranged obliquely upward from bottom to top, which will cause the lower side corner fold to wrap the upper side corner fold, not limited to this embodiment.

[0027] Preferably, a guiding strip 4042 is provided on the third fold angle plate 404, and a guiding groove 11 that facilitates access to the second fold angle groove 6 is formed between the guiding strip 4042 and the tops of the first fold angle plate 402 and the second fold angle plate 403.

[0028] Preferably, a guiding flanging 4043 is provided at the input end of the guiding strip 4042 to facilitate the upper side corner fold of the packaging film to access the guiding groove 11 as the conveyor belt 2 moves.

[0029] Preferably, the fold angle assembly 4 is connected to the machine base 1 in an adjustable manner through an adjusting mechanism 12.

[0030] As Figure 4As shown in the figure, preferably, the adjusting mechanism 12 includes a vertical connecting portion 1201 and a horizontal connecting portion 1202. A vertical limiting groove 1203 is formed in the vertical connecting portion 1201, and a horizontal limiting groove 1204 is formed in the horizontal connecting portion 1202. The fastener passes through the vertical limiting groove 1203 and is connected to the connecting base plate 401, and the fastener passes through the horizontal limiting groove 1204 and is connected to the machine base 1. In this embodiment, the connecting base plate 401 is connected to the inside of the vertical limiting groove 1203 by bolts and nuts. According to the different height dimensions of the paper towel packaging bags to be produced, the position of the connecting base plate 401 in the vertical limiting groove 1203 can be adjusted, so as to flexibly adjust the central height of the folding angle assembly 4; the machine base 1 is connected to the inside of the horizontal limiting groove 1204 by bolts and nuts. According to the different width dimensions of the paper towel packaging bags to be produced, the position of the horizontal connecting portion 1202 on the machine base 1 can be adjusted, so as to flexibly adjust the distance between the two groups of folding angle assemblies 4, so that the folding angle assembly 4 has the functions of height adjustment and width adjustment on the machine base 1, can meet the production requirements of packaging bags of various different size specifications, has a wide application range, high use flexibility, and strong versatility.
