Rectangular frames 4 are fixedly arranged on the top surfaces of the two support plates 2. Vertical rods 13 are fixedly arranged inside the two rectangular frames 4. Rectangular blocks 3 are slidably sleeved on the outer walls of the vertical rods 13. A spring 14 is movably sleeved on the outer wall of the vertical rod 13 on the top surface of the rectangular block 3. The two ends of the spring 14 are fixedly connected to the rectangular block 3 and the rectangular frame 4 respectively. A wind hood 20 is detachably arranged between the two rectangular blocks 3 by screws. A support 17 is fixedly arranged on the top surface of the two support plates 2. An air suction fan 18 is detachably arranged on the top surface of the support 17 by screws. The air suction fan 18 and the wind hood 20 are connected by a corrugated telescopic hose 19. Through openings 12 are provided in one side wall of each of the two rectangular frames 4. A support rod 10 is slidably arranged inside the through opening 12. One end of the support rod 10 is fixedly connected to the rectangular block 3. A nut 11 is threadedly sleeved on the other end of the support rod 10. Move the two support rods 10 up and down along the vertical direction of the through opening 12. The movement of the support rod 10 drives the rectangular block 3 to move inside the rectangular frame 4. The movement of the two rectangular blocks 3 drives the wind hood 20 to adjust its vertical position. Finally, the support rod 10 is fixedly connected to the rectangular frame 4 by the nut 11. By adjusting the height of the wind hood 20, dust suction work can be carried out in different ranges according to the width of the paper, improving the cleanliness for subsequent printing.

[0018] Refer to Figure 3 , on the bottom surfaces of the two support plates 2, connecting plates 1 are fixedly arranged. At both ends of the top surface of the connecting plate 1, a first vertical plate 16 and a second vertical plate 7 are fixedly arranged respectively. Moving openings 23 are provided through the two first vertical plates 16. A sliding rod 21 is fixedly arranged inside the moving opening 23. A moving block 24 is slidably sleeved on the outer wall of the sliding rod 21. A round rod 22 is fixedly arranged between the two moving blocks 24. A connecting frame 25 is fixedly sleeved on the outer wall of the round rod 22. An adjusting roller 15 is movably sleeved on the outer wall of the round rod 22 between the connecting frames 25. The output end of a hydraulic cylinder 26 is fixedly connected to the bottom surface of the connecting frame 25. The bottom surface of the hydraulic cylinder 26 is fixedly provided with a cross plate 27. The cross plate 27 is connected to the two connecting plates 1. The output end of the hydraulic cylinder 26 drives the connecting frame 25 to move vertically up and down. The movement of the connecting frame 25 drives the round rod 22, the adjusting roller 15 and the moving blocks 24 at both ends to move up and down along the vertical direction of the sliding rod 21. By adjusting the height of the adjusting roller 15, it is possible to prevent the paper from slipping or shifting during transmission, thereby improving the stability of paper transmission.
