It is not convenient to limit the position of papers of different widths, and the paper may be easily skewed during transportation. The skewed paper may easily cause paper jams or paper damage in external printing equipment, which is not conducive to the use of the paper feeding device.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The two ends of the inner surface on both sides of the first retention hole 2 are both rotatably installed with a rotating roller 11, and the outer sides of the rotating roller 11 are jointly sleeved and installed with a conveying belt 12. Friction belts 13 are fixed on both sides of the outer surface of the conveying belt 12, and both ends of the upper surface of the fixed plate 1 are slidably installed in the horizontal direction. When the friction belt 13 rotates, the paper on the upper side of the friction belt 13 can be conveyed, and the limiting plate 6 can limit the paper. When in use, it is helpful to limit the paper of different widths during the paper conveying process, so as to ensure the applicable range of the paper feeding device when used, and conveniently limit the paper of different widths, so as to avoid the skew of the paper when conveying, and prevent the paper from causing paper jam or paper damage due to the skew of the paper, which is helpful for the use of the paper feeding device.

[0033] Among them, the inner surfaces of the friction belt 13 are matched and fitted with the corresponding positions of the outer surfaces of the conveyor belt 12, the rotating rollers 11 are in a horizontal state, and a rotating rod 10 is fixed in the middle of the two end surfaces of the rotating rollers 11. The conveyor belt 12 can convey the paper through the friction belt 13; the rotating rods 10 are in a horizontal state, and the ends of the rotating rods 10 away from the rotating rollers 11 pass through the corresponding positions of the corresponding end surfaces of the fixed plate 1. A second retaining hole 3 is opened on the fixed plate 1 corresponding to the rotating rod 10, and the rotating rod 10 helps to rotate and limit the rotating roller 11.

[0034] The second retaining holes 3 on the fixed plate 1 are connected to the first retaining holes 2 on the fixed plate 1, and the outer annular surfaces of the rotating rods 10 are rotatably connected to the corresponding second retaining holes 3 on the fixed plate 1 through bearings. The second retaining holes 3 on the fixed plate 1 help to limit the rotating rod 10; a rotating motor 9 is installed on one side of the surface of one end of the fixed plate 1 corresponding to the rotating rod 10, and the output shaft of the rotating motor 9 faces the corresponding rotating rod 10 and is fixedly connected to the opposite end of the corresponding rotating rod 10. The fixed plate 1 can fix and limit the rotating motor 9.

[0035] Both ends of the upper surface of the fixed plate 1 are fixed with connecting plates 4, and the middle of the surface of the connecting plate 4 away from one side is installed with a hydraulic cylinder 5. The output rods of the hydraulic cylinder 5 are all facing the connecting plate 4 and pass through the two side surfaces of the middle of the corresponding connecting plate 4. The ends of the output rods of the hydraulic cylinder 5 close to the limiting plate 6 are fixedly connected to the middle of the opposite surface of the corresponding limiting plate 6. The connecting plate 4 can fix and limit the hydraulic cylinder 5, which is convenient for the stable use of the hydraulic cylinder 5; the limiting plate 6 is fixed with limiting rods 7 at both ends of the surface of the side away from the other side. The positioning rods 7 pass through the two side surfaces of the corresponding connecting plates 4 at both ends, and limiting holes 8 are provided at both ends of the connecting plates 4 corresponding to the limiting rods 7. The limiting holes 8 and the limiting rods 7 help to limit the connection between the connecting plates 4 and the limiting plates 6; mounting plates 14 are fixed on both sides of the two end surfaces of the fixing plate 1, and bolts 15 are threadedly inserted in the middle of the mounting plates 14 along the horizontal direction. The bolts 15 pass through the two side surfaces of the middle of the corresponding mounting plates 14. The bolts 15 can install and limit the mounting plates 14, which is convenient for use of the mounting plates 14.

[0036] The working principle of the present invention is: during use, the mounting plate 14 is aligned with the corresponding position of the paper feed on the external printing device, and the mounting plate 14 is installed between the corresponding position of the paper feed on the external printing device through the bolts 15. The bolts 15 can fix and limit the mounting plate 14, which is convenient for stable use of the mounting plate 14. The mounting plate 14 can fix and limit the fixing plate 1 and the various components assembled on the fixing plate 1, which is helpful for stable use of the fixing plate 1 and the various components assembled on the fixing plate 1. The fixing plate 1 can support and limit the connecting plate 4 and the various components assembled on the connecting plate 4, which is convenient for stable use of the connecting plate 4 and the various components assembled on the connecting plate 4.

[0037] When it is necessary to adjust the spacing between the limit plates 6 according to the width of the paper, the hydraulic cylinder 5 on the connecting plate 4 is opened. The connecting plate 4 can fix and limit the hydraulic cylinder 5, which helps to use the hydraulic cylinder 5 stably.

When the limit plate 6 moves in the horizontal direction, it helps to adjust the spacing between the limit plates 6.

When the rotating motor 9 is turned on, the output shaft of the rotating motor 9 can drive the rotating rod 10 to rotate along the second retaining hole 3 on the fixed plate 1. When the rotating rod 10 rotates, it can drive the rotating roller 11 to rotate. The fixed plate 1 can limit the rotating roller 11 through the second retaining hole 3 and the rotating rod 10, which helps to stably rotate the rotating roller 11.

[0039] When the rotating roller 11 rotates, it can drive the conveying belt 12 to rotate along the first retention hole 2 on the fixed plate 1. When the conveying belt 12 rotates, it can drive the friction belt 13 to rotate along the first retention hole 2 on the fixed plate 1. When the friction belt 13 rotates, it can convey the paper on the upper side of the friction belt 13. When the paper is conveyed, it will move between the limiting plates 6 to deliver the paper to the paper inlet on the external printing device. The limiting plate 6 can limit the paper to avoid the paper from being skewed when it is conveyed, and prevent the paper from being jammed or damaged due to skew.

[0040] During use, it helps to limit the paper of different widths during paper transportation, so as to ensure the applicable range of the paper feeding device when in use. It is convenient to limit the paper of different widths, which can avoid the paper from being skewed during paper transportation, and prevent the paper from being jammed or damaged due to the skew of the paper, which helps to use the paper feeding device.
