The paper can be lifted by the lifting component to realize paper feeding. When the paper is almost used up, the output end is retracted by driving the second telescopic rods 7 on both sides. At this time, the plug plate 8 can be inserted between the paper and the support plate 4, and then the first telescopic rod 5 is extended out of the output end by driving the first telescopic rod 5. At this time, the paper can continue to be lifted for paper feeding, and then the lifting component is driven to drive the support plate 4 to move down. At this time, a new paper can be placed on the top surface of the support plate 4. After the placement is completed, the lifting component is driven to drive the support plate 4 to move up. When the new paper contacts the bottom surface of the plug plate 8, the second telescopic rod 7 is driven to retract the output end, and then the first telescopic rod 5 is started to retract the output end. At this time, the plug plate 8 can be reset. When the plug plate 8 is retracted, the paper placed for the first time will fall on the top surface of the new paper. At this time, the lifting component is continued to be driven to drive the support plate 4 to move up, thereby realizing continuous paper feeding for the printing press, avoiding pauses in placing new paper when the paper is used up, thereby improving printing efficiency.

[0033] Reference Figure 1-3The discharging assembly includes a top plate 9, a first motor 10, a pickup roller 11 and a discharging plate 12. The two sides of the bottom surface of the top plate 9 are respectively fixedly connected to the top of the support rod 2 and the support frame 3. The first motor 10 is fixedly connected to the middle of one side of the top plate 9. One side of the pickup roller 11 is fixedly connected to the output end of the first motor 10. One side of the discharging plate 12 is fixedly connected to the top of the rear side of the support frame 3. The pickup roller 11 can be driven to rotate by driving the first motor 10. At this time, the paper can be pulled out and slide along the discharging plate 12 to the printing press, thereby completing the paper supply to the printing press.

[0034] Reference Figure 2-3 The material lifting assembly includes a second motor 14, a threaded rod 15, a slide plate 16, a slide bar 17 and a support 18. The second motor 14 is located below the middle of the bottom surface of the support plate 1. The bottom of the threaded rod 15 is fixedly connected to the output end of the second motor 14. The top of the threaded rod 15 is rotatably connected to the middle of the bottom surface of the support plate 1. The slide plate 16 is threadedly connected to the outside of the threaded rod 15. The bottom of the slide bar 17 is fixedly connected to the middle outside of the top surface of the slide bar 16. The top of the outer wall of the slide bar 17 is slidably connected to the middle of the support plate 1. The top of the slide bar 17 is fixedly connected to the bottom surface of the support 18. The support plate 4 is located at the top of the support 18. The middle of the bottom surface of the support plate 1 is fixedly connected with the cover 13. The second motor 14 is fixedly connected to the bottom of the inner wall of the cover 13. The slide plate 16 is slidably connected to the inner wall of the cover 13. The threaded rod 15 can be driven to rotate by driving the second motor 14. At this time, the rotation of the threaded rod 15 can drive the slide plate 16 to slide inside the cover 13, thereby driving the support 18 to move up or down, and further driving the support plate 4 to move up or down.

[0035] Reference Figure 2 and Figure 5 A groove is provided in the middle of the top surface of the support 18, and a protrusion 25 is fixedly connected to the middle of the bottom surface of the support plate 4. The protrusion 25 is located inside the groove, and the support plate 4 is set to be an isosceles trapezoid. By clamping the protrusion 25 inside the groove, the position of the support plate 4 can be limited, and the support plate 4 is set to be an isosceles trapezoid, so that the edges of the paper and the support plate 4 do not touch each other, which is conducive to inserting the inserting plate 8 between the paper and the support plate 4.

[0036] Reference Figure 4The upper inclined plate 20 is fixedly connected to the bottom of the rear side of the support frame 3, the lower inclined plate 19 is fixedly connected to the top of the rear side of the cover shell 13, a horizontal plate 21 is arranged between the upper inclined plate 20 and the lower inclined plate 19, a mounting plate 22 is fixedly connected to one side of the horizontal plate 21, and a mounting hole 23 is provided on the outer side of the middle part of the mounting plate 22. The top and bottom of one side of the mounting plate 22 are fixedly connected to a reinforcing plate 24, and the adjacent sides of the reinforcing plates 24 on both sides are fixedly connected to the top surface and the bottom surface of one side of the horizontal plate 21. The device can be installed on the outside of the printing press through the mounting plate 22 and the mounting hole 23, and the structural strength of the device can be improved through the cooperation between the upper inclined plate 20, the lower inclined plate 19 and the reinforcing plate 24, thereby improving the stability of the device during operation.

[0037] Reference Figure 3 The left and right sides of the top surface of the support plate 1 are fixedly connected with cylinders 26, and the output ends of the cylinders 26 on both sides are fixedly connected with clamps 27. After the new paper is placed, the clamps 27 are pushed out by driving the cylinders 26 on both sides to extend the output ends. At this time, the clamps 27 can be used to correct the position of the paper to prevent it from being offset.

[0038] Working principle: When in use, the device is installed on the outside of the printing press through the mounting plate 22 and the mounting hole 23. When the device is needed to supply paper to the printing press, the threaded rod 15 is driven to be selected by driving the second motor 14, and the slide plate 16 is driven to move downward by the rotation of the threaded rod 15. At this time, the support 18 can be on the top surface of the support plate 1, and then the second telescopic rods 7 on both sides are driven to extend the output end. At this time, the plug plates 8 on both sides can be pushed out to the two sides of the support plate 1, and then the paper can be placed on the top surface of the support plate 4, and then the threaded rods 15 are driven to rotate by the second motor 14 to lift the support 18. At this time, the support plate 4 can drive the paper to move up, and then the first motor 10 is driven. The first motor 10 can drive the pickup roller 11 to rotate, and the paper can be pulled out at this time, so that it slides along the discharge plate 12 to the printing press, thereby completing the paper supply to the printing press. When the paper block is used up, the output end is retracted by driving the second telescopic rods 7 on both sides. At this time, the plug plates 8 on both sides can be close to each other, and the support plate 4 is set to be an isosceles ladder shape, so the edge of the paper and the support plate 4 will not contact, which is conducive to the insertion of the inserting plate 8 between the paper and the support plate 4. When the inserting plate 8 is between the paper and the support plate 4, the first telescopic rod 5 is driven to extend out of the output end, and the paper can continue to be lifted for paper feeding, and then the second motor 14 is driven to drive the support plate 1 to move downward, and a new paper can be placed on the top surface of the support plate 4. After the placement is completed, the clamping plate 27 is pushed out by driving the cylinders 26 on both sides to extend out of the output end, and the position of the paper can be corrected at this time. Finally, the second motor 14 is driven to drive the paper to move up. When the new paper contacts the bottom surface of the inserting plate 8, the second telescopic rod 7 is driven to retract the output end, and then the first telescopic rod 5 is started to retract the output end. At this time, the inserting plate 8 can be reset. When the inserting plate 8 is retracted, the paper placed for the first time will fall on the top surface of the new paper. At this time, the second motor 14 is continued to be driven to drive the support plate 4 and the paper to move, so as to realize continuous paper feeding for the printing press, and avoid pauses in placing new paper when the paper is used up.
