Detailed implementation manners

[0023] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings for a more detailed description.

[0024] The embodiment of this application discloses a paper feeding mechanism of a printing device. Referring to Figures 1-4 , a paper feeding mechanism of a printing device includes a movable shaft 2, a support platform 3 and a push plate 8. One end of the support platform 3 is fixedly connected to a first motor 4. One end of the first motor 4 inside the support platform 3 is fixedly connected to a threaded rod 11. The push plate 8 is movably installed on the top of the support platform 3. The bottom of the push plate 8 is welded with a movable block 802 embedded inside the support platform 3. The threaded rod 11 penetrates through the movable block 802. The inside of the movable block 802 is provided with a threaded hole adapted to the threaded rod 11. Stacked paper is placed on the top of the support platform 3. By controlling the second motor 5 to drive the threaded rod 11 to rotate, the push plate 8 is made to push the stacked paper into an external printing paper cutting device. One end of the top of the support platform 3 is provided with a movable shaft 2 ，A second motor 5 is installed on one side of the movable shaft 2. By sleeving the roll-type printing paper around the periphery of the movable shaft 2 and then passing it through the limiting roller frame 10, the second motor 5 drives the movable shaft 2 to rotate, so that the roll-type printing paper is conveyed into the external printing equipment. The height of the movable shaft 2 is higher than that of the push plate 8. When the roll-type printing paper is conveyed, the printing paper is conveyed at the upper end of the push plate 8. Therefore, the push plate 8 will not interfere with the conveyance of the roll-type printing paper. A length measuring wheel 6 is installed at the top of the movable shaft 2. The limiting roller frame 10 is movably installed on the outside of the support table 3. The limiting roller frame 10 can assist in supporting and guiding the printing paper, improving the conveyance stability effect of the printing paper. One side of the surface of the push plate 8 is fixedly connected with a distance measuring instrument 14. Connect the external control equipment to the device and set the paper feeding length and distance. When the roll-type printing machine prints, it drives the length measuring wheel 6 to rotate. The paper feeding length is detected by the length measuring wheel 6. When the detected paper feeding length reaches the set length, the second motor 5 stops. The distance measuring instrument 14 can detect the push plate 8 and the paper pushing distance. When the detected distance reaches the set distance, the external control equipment controls the first motor 4 to stop, realizing the control of the paper feeding length. The distance measuring instrument 14 and the length measuring wheel 6 are both well-known common knowledge, so no more details will be described.

[0025] Refer to Figure 1 and Figure 4 , a fixing bolt 7 is movably installed between the limiting roller frame 10 and the support table 3. Threaded holes 302 are provided on both sides inside the support table 3, and the fixing bolt 7 is threadedly connected with the threaded holes 302. By screwing the fixing bolt 7 into the threaded holes 302 between the limiting roller frame 10 and the support table 3, the limiting roller frame 10 can be installed and fixed on the support table 3. By unscrewing the fixing bolt 7, the limiting roller frame 10 can be pulled out for disassembly.

[0026] Refer to Figure 2 , an extension plate 9 is movably installed on the top of the push plate 8. A positioning bolt 901 is movably installed between the extension plate 9 and the push plate 8. A bolt hole 801 is provided inside the push plate 8, and the positioning bolt 901 is threadedly connected with the bolt hole 801. Multiple extension plates 9 can be installed on the top of the push plate 8 as needed, and then the positioning bolt 901 is screwed into the bolt hole 801 to fix the extension plate 9 and the push plate 8, extending the push plate 8 so that the device can push more papers.

[0027] Refer to Figure 2 and Figure 3 , a limiting plate 1 is movably installed on the top of the support table 3 on one side of the movable shaft 2. A limiting rod 12 is movably installed between the limiting plate 1 and the support table 3. A fixing hole 13 is provided inside the support table 3 on the side where the limiting plate 1 is close to each other, and the limiting rod 12 is threadedly connected with the fixing hole 13. The paper roll is limited by the limiting plate 1. By unscrewing the limiting rod 12 and then pulling out and disassembling the limiting plate 1, the paper roll can be sleeved around the periphery of the movable shaft 2.

[0028] Refer toFigure 1 On both sides of the threaded rod 11, the support platform 3 is provided with a limiting groove 301 inside, and the push plate 8 is fitted with the limiting groove 301. Through the limiting groove 301, the moving direction of the push plate 8 can be guided and limited, improving the stability effect of the movement of the push plate 8.

[0029] The implementation principle of the paper feeding mechanism of a printing device in an embodiment of the present application is as follows: By sleeving the roll-type printing paper onto the periphery of the movable shaft 2, the second motor 5 drives the movable shaft 2 and the roll-type printing paper to be conveyed into the external printing device. The height of the movable shaft 2 is higher than that of the push plate 8. When the roll-type printing paper is conveyed, the printing paper is conveyed above the push plate 8. Therefore, the push plate 8 will not interfere with the conveyance of the roll-type printing paper. Also, the stacked paper can be placed on the top of the support platform 3, at the rear end of the push plate 8, so that the push plate 8 frames the stacked paper, and the push plate 8 limits the movement range of the stacked paper. By driving the threaded rod 11 to rotate through the second motor 5, the push plate 8 pushes the paper into the external printing paper cutting device. When the roll-type printing press prints, it drives the meter wheel 6 to rotate. When the meter wheel 6 detects that the paper feeding length reaches the set length, the second motor 5 stops. When the rangefinder 14 detects that the distance reaches the set distance, the first motor 4 stops, realizing the control of the paper feeding length.
