[0025] The printer guide mechanism facilitating paper feeding comprises a printer body 1, a paper supporting plate 2 arranged on the printer body 1, two sliding grooves 3 arranged on the paper supporting plate 2, two positioning clamps 4 slidingly arranged on the two sliding grooves 3 respectively, two fixing blocks 5 fixedly installed on the paper supporting plate 2, a bidirectional screw rod 6 rotatably installed between the two fixing blocks 5, a supporting block 7 threadedly connected with the two positioning clamps 4 and fixedly installed on the paper supporting plate 2 and rotatably connected with the bidirectional screw rod 6, and a transmission mechanism arranged on the printer body 1 for pushing the paper to move forward, which is correspondingly arranged with the paper supporting plate 2, can limit the positioning clamps 4 through the two sliding grooves 3 arranged on the paper supporting plate 2, and can drive the positioning clamps 4 through the fixing blocks 5 fixedly installed on the paper supporting plate 2 for fixing the bidirectional screw rod 6, so that the bidirectional screw rod 6 can drive the positioning clamps 4 to move by the same distance, which is beneficial to keep the paper in the central position and prevent paper jam, and the transmission mechanism can push the paper to move forward and prevent the paper from deviating during conveying.

[0026] The transmission mechanism comprises two driving rods 8, two stabilizing blocks 9, a paper feeding wheel 10, a resistance pad 11, an adjusting mechanism and a driving mechanism, the two driving rods 8 are rotatably installed on the paper supporting plate 2, the two stabilizing blocks 9 are arranged on the two driving rods 8 respectively, the paper feeding wheel 10 is arranged between the two stabilizing blocks 9, the paper feeding wheel 10 is correspondingly arranged with the paper supporting plate 2, the resistance pad 11 is sleeved on the paper feeding wheel 10, the adjusting mechanism is arranged on the paper feeding wheel 10 for adjusting the height of the resistance pad 11 that can be contacted, and the driving mechanism is arranged on the printer body 1 for driving the paper feeding wheel 10 to rotate, the two stabilizing blocks 9 are fixed through the driving rods 8, the paper feeding wheel 10 is clamped by the two stabilizing blocks 9, and the resistance pad 11 sleeved on the paper feeding wheel 10 can increase the friction force between the paper feeding wheel 10 and the paper, which is beneficial to stabilize the paper by the paper feeding wheel 10 and push the paper to move forward into the printer body 1 for printing.

[0027] The adjusting mechanism comprises two telescopic rods 12 and an arc-shaped block 13, the two telescopic rods 12 are fixedly installed on the paper feeding wheel 10, the arc-shaped block 13 is fixedly installed on the two telescopic rods 12 and extends out of the paper feeding wheel 10, and the arc-shaped block 13 abuts against the resistance pad 11, so that the resistance pad 11 abutting against the arc-shaped block 13 can abut against the paper by pushing the arc-shaped block 13 through the telescopic rods 12 to change the shape of the paper feeding wheel 10, which is beneficial to adapt to the printing of paper with different thicknesses and fix the paper at the same time.

[0028] The drive mechanism includes a mounting cavity 14, a first bevel gear 15, a drive motor 16, and a second bevel gear 17. The mounting cavity 14 is located on the printer body 1. The first bevel gear 15 is fixedly mounted on the drive rod 8. The drive motor 16 is fixedly mounted inside the mounting cavity 14. The second bevel gear 17 is fixedly mounted on the output shaft of the drive motor 16. The second bevel gear 17 meshes with the first bevel gear 15. The drive mechanism can drive the paper feed roller 10 to rotate. The drive motor 16 drives the second bevel gear 17 to rotate. The first bevel gear 15, which meshes with the second bevel gear 17, drives the drive rod 8 to rotate. This facilitates the rotation of the paper feed roller 10 to complete paper feeding, allowing the paper to move only forward.

[0029] Both of the stabilizing blocks 9 are provided with movable cavities 18, which are correspondingly arranged with the drive rod 8. Springs 19 are fixedly installed in both movable cavities 18. There are multiple springs 19. The position of the stabilizing block 9 can be changed by moving the stabilizing block 9 to both sides to disengage the paper feeding wheel 10. This is beneficial for replacing the resistance pad 11 fitted on the paper feeding wheel 10 and prevents the resistance pad 11 from wearing out, which would make it difficult to fix and feed the paper.

[0030] Each of the two stabilizing blocks 9 is fixedly equipped with a locking block 20, and the two locking blocks 20 are respectively set to correspond to the paper feeding roller 10. The locking blocks 20 can fix the stabilizing block 9 and the paper feeding roller 10, and prevent the spring 19 from being compressed during operation, which would cause the stabilizing block 9 to separate from the paper feeding roller 10.

[0031] The interface between the stabilizing block 9 and the paper feeding roller 10 is serrated, and the paper feeding roller 10 is elliptical. By serrifying the interface between the stabilizing block 9 and the paper feeding roller 10, friction can be increased to ensure the fixing effect. The elliptical shape of the paper feeding roller 10 facilitates the adjustment of the convex arc surface of the paper feeding roller 10, which is beneficial to adapting to the transmission of paper of different sizes.

[0032] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0033] The working principle of the printer guide mechanism for easy paper feeding provided by this utility model is as follows:

[0034] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0035] When using, first place the paper on the paper tray 2, rotate the double-ended screw 6, and make the two positioning clips 4 connected to the double-ended screw 6 move towards the middle at the same time. The positioning clips 4 fix the paper. Since the positioning clips 4 are connected to the double-ended screw 6, the distance between the two ends is equal, so that the paper is in the middle position.

[0036] The operation of the telescopic rod 12 is related to the paper thickness. When the paper is thin, the telescopic rod 12 needs to be controlled to extend outward and push the arc block 13 to contact the resistance pad 11. The resistance pad 11 is elastic. When the resistance pad 11 extends outward and contacts the paper, it can fix the paper and ensure that the paper does not shift during printing while being fed into the printer.

[0037] The drive motor 16 controls the second bevel gear 17 to rotate, and the second bevel gear 17 drives the first bevel gear 15 to rotate. The drive rod 8, which is fixedly installed on the first bevel gear 15, drives the paper feeding wheel 10 to rotate. The drive rod 8 fixes the stabilizing block 9 and the paper feeding wheel 10 together through the locking block 20. The paper feeding wheel 10 is generally elliptical, and the protruding part contacts the paper to complete the paper feeding operation, which facilitates printing.

[0038] Compared with related technologies, the printer guide mechanism for easy paper feeding provided by this utility model has the following advantages:

[0039] This utility model provides a printer guide mechanism that facilitates paper feeding. Two grooves 3 on the paper tray 2 limit the positioning clamps 4. A fixing block 5 is fixedly installed on the paper tray 2 to fix a bidirectional screw 6, allowing the bidirectional screw 6 to drive the positioning clamps 4. The bidirectional screw 6 ensures that the two positioning clamps 4 move the same distance, helping to keep the paper centered and prevent paper jams. The conveying mechanism pushes the paper forward while preventing paper deviation during transport. Two stabilizing blocks 9 are fixed by a drive rod 8, clamping the paper feed roller 10. A resistance pad 11 is fitted on the paper feed roller 10 to increase the friction between the roller and the paper, stabilizing the paper while pushing it forward into the printer body 1 for printing. A telescopic rod 12 pushes an arc-shaped block 13 to change the overall shape of the paper feed roller 10, allowing the resistance pad 11, which is pressed against by the arc-shaped block 13, to contact the paper, facilitating printing on paper of different thicknesses. The paper is fixed in place. The drive mechanism drives the paper feed roller 10 to rotate. The drive motor 16 drives the second bevel gear 17 to rotate. The first bevel gear 15, which meshes with the second bevel gear 17, drives the drive rod 8 to rotate. This facilitates the rotation of the paper feed roller 10 to complete the paper feeding, allowing the paper to move only forward. The position of the stabilizing block 9 can be changed by the movable cavity 18 and the spring 19. Moving the stabilizing block 9 to both sides disengages the paper feed roller 10 from it, which is beneficial for replacing the resistance pad 11 fitted on the paper feed roller 10 and preventing the resistance pad 11 from wearing out and making it difficult to fix and feed the paper. The locking block 20 can fix the stabilizing block 9 and the paper feed roller 10, preventing the spring 19 from being compressed during operation and causing the stabilizing block 9 to disengage from the paper feed roller 10. Setting the interface between the stabilizing block 9 and the paper feed roller 10 as serrated can increase friction and ensure the fixing effect. The paper feed roller 10 is set as an ellipse, which facilitates the adjustment of the convex arc surface of the paper feed roller 10 and is conducive to the transmission of paper of different sizes.
