A lower paper frame 22 is slidably arranged on the lower paper slot, and the printing plate 23 is located between the upper paper slot and the lower paper slot; the hot stamping component is arranged on the top frame 2 and is located above the printing plate 23.

[0021] The paper loading assembly is arranged at the paper loading slot, and the paper loading assembly includes a hydraulic cylinder b10 arranged at the bottom end of the frame 1, a telescopic plate 11 connected to the output end of the hydraulic cylinder b10, a motor b12 arranged on the frame 1, a driving rod 13 connected to the output end of the motor b12, a bidirectional screw rod 14 coaxially arranged on the driving rod 13, two clamping plates 15 relatively arranged on the bidirectional screw rod 14, and a conveying assembly arranged on each of the two clamping plates 15. The telescopic plate 11 is respectively provided with lifting assemblies at both ends of the two clamping plates 15, and the lifting assemblies can reduce the friction between the telescopic plate 11 and the clamping plate 15 when the telescopic plate 11 is lifted and lowered. There are two hydraulic cylinders b10 at the bottom end of the frame 1, and the connection points between the output ends of the two hydraulic cylinders b10 and the telescopic plate 11 are symmetrical to each other; the feeding assembly is arranged on the frame 1 and the top frame 2; the fixed conveying assembly is arranged on the frame 1 and the printing plate 23.

[0022] When this embodiment is used, a worker places a pile of papers on the telescopic plate 11 at the upper paper slot, and the motor b12 drives the bidirectional screw 14 to rotate through the driving rod 13, and the bidirectional screw 14 drives the two clamping plates 15 to move toward the papers until the two clamping plates 15 fix the papers, and the hydraulic cylinder b10 drives the telescopic plate 11 to rise, and the conveying assembly on the clamping plate 15 places the papers on the printing plate 23 one by one, and the fixed conveying assembly fixes the papers to the position required by the workers, and the hot stamping assembly hot stamps the papers through the feeding assembly. After the hot stamping of the papers is completed, the fixed conveying assembly sends the papers to the lower paper rack 22, so that the pressure on each paper is consistent, avoiding the hot stamping quality of the papers failing to meet customer requirements.

[0023] Embodiment 2

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, a paper product printing and hot stamping machine proposed in this embodiment, compared with the first embodiment, in this embodiment, the fixed conveying assembly includes a driving block 18 slidably arranged on the frame 1, two fixing frames 19 relatively slidably arranged on the printing plate 23, a motor b20 arranged on the printing plate 23, and a conveying roller 21 rotatably arranged on the printing plate 23, the motor b20 is connected to the paper loading roller 17, the driving block 18 and the fixing frame 19 are each connected to a driving assembly, and the conveying roller 21 has a plurality of elastic blocks evenly arranged along the outer circumference, and the surface of the elastic block is distributed with a texture that increases friction.

[0025] In this embodiment, after the paper is conveyed onto the printing plate 23, the driving component drives the driving block 18 to push the paper between the two fixing frames 19. The distance between the two fixing frames 19 is gradually reduced under the drive of the driving component, so that the two fixing frames 19 and a driving block 18 fix the paper to the position where the paper needs to be processed. After the paper is gold-stamped, the driving block 18 pushes the paper to contact the elastic block on the conveying roller 21, and the elastic block sends the paper to the lower paper rack 22, thereby avoiding the worker manually taking down the paper, thereby reducing the worker's work intensity.
