Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application; based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0023] As shown in the figures Figure 1 and Figure 2 , a paper deviation preventing device of an ink printing machine, comprising a mounting plate 1, the upper side middle part of the mounting plate 1 is provided with a printing table 3, the lower side of the printing table 3 is fixedly installed on the upper side of the mounting plate 1, a paper conveying assembly is installed on the upper side of the mounting plate 1, the paper conveying assembly comprises two groups of conveying belts one 9, the two groups of conveying belts one 9 are respectively located on both sides of the printing table 3, the upper side walls of the printing table 3 are respectively provided with slots 4, the upper parts of the conveying belts one 9 pass through the inner sides of the slots 4, and the upper sides are on the same plane as the upper side of the printing table 3; when a printing head prints paper, the bottom of the paper is ensured to have a flat supporting surface, the lower parts of the conveying belts one 9 move on the lower side of the printing table 3 and do not contact the support blocks 2, so that the support blocks 2 do not limit the conveying belts one 9.

[0024] As shown in the figures Figure 3 , the paper conveying assembly further comprises U-shaped frames one 5, pivots one 6, limiting rotating wheels one 7 and a motor 8, the U-shaped frames one 5 comprise two groups and are fixedly installed on the feeding side and the discharging side of the printing table 3 respectively, the pivots one 6 comprise two groups and are rotatably installed between the two side walls of the U-shaped frames one 5 respectively, two groups of limiting rotating wheels one 7 are installed on the outer side of each group of pivots one 6, the conveying belts one 9 are sleeved on the outer sides of the corresponding two groups of limiting rotating wheels one 7, and the motor 8 is installed on the side wall of one group of U-shaped frames one 5 and drives the pivots one 6 to rotate through the shaft end.

[0025] As attached Figure 3 As shown, the paper conveying assembly has an extended feeding assembly connected to the feeding side. The extended feeding assembly includes a U-shaped frame 15, a rotating shaft 16, a limiting wheel 17, and a conveyor belt 18. The U-shaped frame 15 is fixedly installed on the upper side of the mounting plate 1. The rotating shaft 16 is rotatably installed between the two side walls of the U-shaped frame 15. The limiting wheel 17 includes two sets. One set of limiting wheels 17 is installed on the outer side of the middle of one set of rotating shafts 16 on the feeding side, and the other set of limiting wheels 17 is installed on the outer side of the middle of rotating shaft 16. The conveyor belt 18 is sleeved on the outer side of the two sets of limiting wheels 17. When the conveyor belt 9 rotates, it drives the conveyor belt 18 to rotate simultaneously.

[0026] As attached Figure 1 and attached Figure 4 As shown, the mounting plate 1 has two sets of annular limiting plates 12 on its upper side. The two sets of annular limiting plates 12 are located on the outer sides of the two sets of conveyor belts 9. Multiple sets of positioning rollers 13 are rotatably installed on the upper part of the annular limiting plate 12 near the printing table 3. An arc-shaped positioning plate 14 is installed on the side of the annular limiting plate 12 near the extended feeding assembly. The two sets of arc-shaped positioning plates 14 are located on both sides of the second conveyor belt 18 to correct the position of the paper conveyed on the second conveyor belt 18 and then limit it between the two sets of annular limiting plates 12.

[0027] A pushing assembly is installed on the upper side of the mounting plate 1. The pushing assembly includes a vertical plate 10 and a hand-tightening bolt 11. The vertical plate 10 is installed on the upper side of the mounting plate 1 and is located on the side where the two sets of conveyor belts 9 are far apart. The hand-tightening bolt 11 passes through the vertical plate 10 by threads and is rotatably connected to the annular limiting plate 12. The hand-tightening bolt 11 is located below the conveyor belt 9 and adjusts the position of the annular limiting plate 12 outside the conveyor belt 9.

[0028] The specific usage method is as follows:

[0029] Before starting the ink printing machine, adjust the position of the annular limiting plate 12 according to the paper width, and turn the hand-tightening bolt 11. The hand-tightening bolt 11 passes through the vertical plate 10 and pushes the annular limiting plate 12 to move outside the conveyor belt 9. The conveyor belt 9 and the mounting plate 1 limit the annular limiting plate 12 to prevent it from rotating with the hand-tightening bolt 11. The hand-tightening bolt 11 pushes the annular limiting plate 12 to move outside the conveyor belt 9 so that the distance between the two sets of annular limiting plates 12 meets the paper width requirements.

[0030] After the ink printer is started, the motor 8 drives a set of rotating shafts 6 to rotate, so that the two sets of limiting rotating wheels 7 outside the rotating shafts 6 rotate, drive the two sets of conveying belts 9 to rotate, and the other set of rotating shafts 6 drives the limiting rotating wheels 17 to rotate, thereby driving the conveying belt 18 to rotate at the same time, and the paper is fed through the conveying belt 18. During the conveying of the paper by the conveying belt 18, the paper is position corrected by the two sets of arc-shaped positioning plates 14, so that the paper moves stably between the two sets of annular limiting plates 12, and deviation of the paper during the conveying is prevented.
