[0021] Embodiment 1, in combination with the attached Figure 1 A paper feeding mechanism for a die-cutting machine comprises an operating table 1, wherein feet 2 are arranged below the operating table 1 and near both ends, and anti-skid pads are arranged at the lower ends of the feet 2 to increase friction and ensure stable placement; a material storage box 3 is arranged above the operating table 1; a paper feeding mechanism is arranged above the material storage box 3, and the paper feeding mechanism comprises a silo 4, which is a hollow cylinder and has openings at the upper and lower ends for easy loading from the upper end and unloading from the lower end, and support side plates 5 are movably arranged at the front and rear ends of the silo 4, and threaded rods 6 are arranged at the front and rear sides and near both ends of the silo 4, and through grooves 7 that can be slidably connected to the threaded rods 6 are arranged on the supporting side plates 5, and locking nuts 8 are threadedly connected to the outer sides of one end of the threaded rod 6 extending out of the through groove 7, and the threaded rod 6 and the silo 4 are positioned by the locking nuts 8 to fix their heights.

[0022] According to the attached Figure 1 , 3 , scale lines 9 are provided on the supporting side plates 5, and the scale lines 9 are convenient for observing the height of the lower end of the silo 4 exposed, so as to facilitate adjustment according to the cardboard.

[0023] According to the attached Figure 3 A cardboard limiting structure is provided in the silo 4, and the cardboard limiting structure includes threaded holes 10 provided on both sides of the silo 4, and threaded rods 11 are threadedly connected in the threaded holes 10, and the opposite ends of the threaded rods 11 extend into the silo 4 and are rotatably provided with limiting plates 12, and the ends of the threaded rods 11 that are away from each other extend out of the silo 4 and are provided with knobs 13; the cardboard limiting structure can limit the smaller cardboard to prevent it from collapsing when stacked, and leave a margin when limiting to avoid affecting the falling of the cardboard.

[0024] According to the attached Figure 1 , 4 A pushing assembly is provided on one side of the storage box 3, and the pushing assembly includes a support platform, on which an electric push rod 19 is provided, and a push plate 20 is provided at the output end of the electric push rod 19, and the push plate 20 can extend to the lower end of the silo 4 and between the supporting side plates 5. The cardboard can be pushed out by the electric push rod 19 and the push plate 20. In actual applications, the push plate 20 can be set to be thinner, so that it is suitable for cardboards of different heights, and has strong applicability.

[0025] Embodiment 2, combined with the attached Figure 1 A material storage mechanism is provided on the material storage box 3. The material storage mechanism includes a blanking port 14 provided on the material storage box 3. An L-shaped support frame 15 is provided on the material storage box 3 and located behind the blanking port 14. A die-cutting mechanism is provided at the upper end of the support frame 15. An electric push rod 16 is provided at the upper end of the material storage box 3. A baffle 17 capable of covering the blanking port 14 is provided at the output end of the electric push rod 16.
