A material conveying cylinder 4 is arranged inside the printing cylinder 3, and an inner scraping mechanism 10 is arranged inside the material conveying cylinder 4. The inner scraping mechanism 10 includes two inner fixing rods 15, a rotating ring 18, a retaining ring 22, two nuts 13, two sleeves 14, two sealing rings 12, a plurality of inner connecting blocks 16, and two inner scraping plates 17. Two outer fixing rods 7 are arranged outside the material conveying cylinder 4, and two fixing blocks 6 are fixed to the outer side walls of the outer fixing rods 7. The fixing blocks 6 are fixedly connected to the inner side walls of the material conveying cylinder 4. The left end of the material conveying cylinder 4 is rotatably connected to a circular ring 5. A plurality of outer connecting blocks 8 are fixed to the outer side walls of the outer fixing rods 7 between the two fixing blocks 6. One end of the outer connecting block 8 away from the material conveying cylinder 4 is fixed with an outer scraping plate 9. An inner cylinder 19 is integrally formed inside the material conveying cylinder 4. The outer side wall of the inner cylinder 19 is rotatably connected to the inner side wall of the rotating ring 18. The outer side wall of the inner cylinder 19 is fixedly connected to the inner side wall of the retaining ring 22 on the left side of the rotating ring 18. The right end of the inner fixing rod 15 is fixedly connected to the left side of the rotating ring 18. The inner connecting block 16 is fixed to the outer side wall of the inner fixing rod 15. The inner connecting block 16 is fixedly connected to the inner scraping plate 17. The left end of the inner fixing rod 15 passes through the left end cap 2. The sealing ring 12 is sleeved on the outer side of the inner fixing rod 15. The nut 13 is screwed to the inner fixing rod 15. The right end of the sleeve 14 is fixedly connected to the left end of the nut 13. A connecting mechanism 11 is arranged inside the right end cap 2. The connecting mechanism 11 includes a circular block 24 and two clamping blocks 23. The inner fixing rod 15 is fixedly connected to the left end cap 2. In this way, when the material conveying cylinder 4 rotates, the inner scraping plate 17 scrapes the inner side wall of the material conveying cylinder 4, preventing some materials from remaining on the inner side wall of the material conveying cylinder 4 and scraping all the materials into the inner part of the discharge hole.

[0023] Furthermore, the right end of the circular block 24 passes through the right end cap 2 and is fixedly connected to the end of the rotating shaft 25.
