An upper guide roller 7 is provided between the first vertical plates 1 near the top via a second rotating shaft 4. A lower guide roller 5 is connected between the first vertical plates 1 near the lower end of the upper guide roller 7 via a first rotating shaft 3.

[0023] An annular protrusion 8 is provided near the center of the outer periphery of the upper guide roller 7 and the tension roller 16, and a groove 6 is provided near the center of the outer periphery of the lower guide roller 5. A servo motor 17 is provided on one side of the bottom end of the second vertical plate 2 through a fixed seat, and the power output end of the servo motor 17 is connected to a screw rod 18, and a wire block 22 is connected to the outer side of the screw rod 18. A fixing plate 21 is welded to one side of the wire block 22, and a connecting column 20 is provided near the corner on one side of the fixing plate 21, and the end of the connecting column 20 is connected to the first slider 14.

[0024] When in use, the output end of the servo motor 17 can drive the screw 18 to rotate, so that the wire block 22, the fixed plate 21, the connecting column 20 and the first slider 14 are lifted and moved along the direction of the guide groove 13, thereby facilitating the adjustment of the upper and lower heights of the tension roller 16. When the paper is fed, it first passes between the upper guide roller 7 and the lower guide roller 5, and then passes through the upper end of the tension roller 16. The tension roller 16 can provide a certain vertical tension to the paper. Through the annular protrusion 8 and the groove 6, the part near the middle of the paper can be slightly concave when feeding, thereby effectively improving the strength of the paper and preventing paper jams during transportation.

[0025] For example, Figure 1 As shown, the present invention further includes that a vertical block 19 is provided on one side of the second vertical plate 2 near the upper end of the guide groove 13, a bearing is provided at the bottom of the vertical block 19, and the top end of the screw rod 18 is located in the bearing.

[0027] For example, Figure 1 and Figure 3 As shown, the utility model also includes that one end of the first vertical plate 1 is connected to a connecting block 9 near the upper guide roller 7 and the lower guide roller 5 through a connecting bolt 10, and one side of the connecting block 9 is connected to a limiting baffle 11.

[0028] When in use, the connecting block 9 and the limiting baffle 11 are conveniently fixed and installed through the connecting bolts 10, and the limiting baffle 11 is convenient for preliminary limiting and guiding of the paper before feeding to prevent the paper from falling out from both sides.

[0029] For example, Figure 2 As shown, the utility model also includes that the bottom side of the second slider 24 is connected to an extension plate 25, the bottom side of the extension plate 25 is connected to a first mounting plate 26, the top of the first mounting plate 26 is provided with a first drive motor 27 through a fixed seat, the output end of the first drive motor 27 is connected to a first active bevel gear 28, and one side of the third rotating shaft 15 is connected to a first driven bevel gear 29 through an extension shaft, and the first driven bevel gear 29 is meshed with the first active bevel gear 28.

[0030] When in use, the output end of the first drive motor 27 can drive the first active bevel gear 28 to rotate. When the first active bevel gear 28 rotates, it drives the first driven bevel gear 29 and the third rotating shaft 15 to rotate, thereby driving the tension roller 16 to rotate.

[0031] For example, Figure 2As shown, the utility model also includes a second mounting plate 30 provided at one side of the first vertical plate 1 near the upper end of the first rotating shaft 3, a second driving motor 31 is provided on the top of the second mounting plate 30 through a fixed seat, the power output end of the second driving motor 31 is connected to a second active bevel gear 32, and a second driven bevel gear 33 is provided on one side of the second rotating shaft 4 through a fixed shaft, and the second driven bevel gear 33 is meshed with the second active bevel gear 32.

[0032] When in use, the output end of the second driving motor 31 drives the second active bevel gear 32 to rotate, thereby causing the second driven bevel gear 33 and the second rotating shaft 4 to rotate, and further driving the upper guide roller 7 to rotate.

[0033] For example, Figure 1-3 As shown, the present invention also includes a first connecting plate 23 connected between the first vertical plate 1 and the second vertical plate 2 and the third vertical plate 12, and a second connecting plate 34 is connected between the bottom ends of the two groups of first vertical plates 1 and between the bottom ends of the second vertical plate 2 and the third vertical plate 12.

[0034] When in use, the first connecting plate 23 is used to facilitate the connection between the second vertical plate 2 and the third vertical plate 12, and the second connecting plate 34 is used to facilitate the connection between the second vertical plate 2 and the bottom end of the third vertical plate 12, and the bottom ends of the two groups of first vertical plates 1 are connected, so that the first vertical plate 1, the second vertical plate 2 and the third vertical plate 12 are highly stable as a whole.

[0035] When the utility model is in use, the output end of the first driving motor 27 can drive the first active bevel gear 28 to rotate. When the first active bevel gear 28 rotates, it drives the first driven bevel gear 29 and the third rotating shaft 15 to rotate, thereby driving the tension roller 16 to rotate. The output end of the second driving motor 31 drives the second active bevel gear 32 to rotate, thereby rotating the second driven bevel gear 33 and the second rotating shaft 4, thereby driving the upper guide roller 7 to rotate. The connecting bolts 10 are used to facilitate the fixing and installation of the connecting block 9 and the limit baffle 11. The limit baffle 11 is used to facilitate the preliminary limit guidance of the paper before feeding to prevent the paper from falling out from both sides.

[0036] The output end of the servo motor 17 can drive the screw 18 to rotate, so that the wire block 22, the fixed plate 21, the connecting column 20 and the first slider 14 are moved up and down along the direction of the guide groove 13, thereby facilitating the adjustment of the upper and lower heights of the tension roller 16. When the paper is fed, it first passes between the upper guide roller 7 and the lower guide roller 5, and then passes through the upper end of the tension roller 16. The tension roller 16 can provide a certain vertical tension to the paper. Through the annular protrusion 8 and the groove 6, the part near the middle of the paper can be slightly concave when feeding, thereby effectively improving the strength of the paper and preventing paper jams during transportation.
