[0004] Preferably, baffles adapted to the top ends of the limiting columns are provided on both sides of the bottom of the support frame.

[0005] Preferably, the outer thread of the bottom end of the limiting column is sleeved with a second nut.

[0006] Preferably, the limiting mechanism includes a limiting plate arranged outside the limiting disk, the internal thread of the limiting plate is sleeved with a bolt, and the outer thread of one end of the bolt is sleeved with a first nut located between the limiting disk and the limiting plate.

[0007] Preferably, a limiting hole adapted to fit the bolt is provided on the outer side of the limiting plate. Beneficial effects

[0008] 1. The support roller structure of the three-layer SSB forming mesh of the papermaking machine can rotate the support roller fixed inside the support around the axial direction of the rotating shaft by loosening the limiting column, so that the support roller can be leveled. The support roller can be limited and fixed by the reinforcing plate while tightening the limiting column. This structure can quickly level the support roller and is convenient for manual adjustment.

[0009] 2. The support roller structure of the three-layer SSB forming mesh of the papermaking machine can be tightened by tightening the bolts so that the limit plate can be pressed and fixed on the outside of the support roller, and then the forming mesh sleeved on the outside of the support roller can be limited by the limit plate to prevent the forming mesh from deflecting. By loosening the bolts, the support roller structure can adjust the distance between the two limit plates according to the width of the forming mesh. BRIEF DESCRIPTION OF THE DRAWINGS

The support roller 8 is connected to the support frame 6 by the shaft 5. The support roller 8 is connected to the support frame 6 by the shaft 5. The support roller 8 is connected to the support frame 6 by the shaft 5. The support roller 8 is connected to the support frame 6 by the shaft 5. The support roller 8 is connected to the support frame 6 by the shaft 5. The support roller 8 is fixedly mounted on the top of the support frame 6. The support roller 8 is connected to the support frame 6 by the shaft 5. The outer sides of the two ends of the support roller 8 are movably sleeved with limit plates 9. The outer side of the limit plate 9 is provided with a limit mechanism 10. The inner thread of the support block 3 is sleeved with a limit column 11 located below the support frame 6. The inner sides of the support frame 6 are provided with a reinforcing plate 12. The structural strength of the support frame 6 can be enhanced by the reinforcing plate 12, so that the support frame 6 is not easily bent when subjected to external force.

[0020] Among them, baffles 13 that are compatible with the top of the limiting column 11 are provided on both sides of the bottom of the support frame 6. The baffles 13 can limit the top of the limiting column 11 and the support frame 6 at the same time, so that the support frame 6 is not easily offset.

[0021] Among them, the outer thread of the bottom end of the limiting column 11 is equipped with a second nut 14. By tightening the limiting column 11, the support frame 6 can be supported and fixed, so that there is supporting force on both sides of the support frame 6, thereby ensuring that the support frame 6 can stably limit the support roller 8.

[0022] Among them, the limiting mechanism 10 includes a limiting plate 101 arranged on the outside of the limiting plate 9, and the internal thread of the limiting plate 101 is sleeved with a bolt 102, and the outer thread of one end of the bolt 102 is sleeved with a first nut 103 located between the limiting plate 9 and the limiting plate 101. By tightening the first nut 103, the bolt 102 can be limited and fixed, so that it is not easy to loosen, thereby ensuring that after the bolt 102 is tightened, the limiting plate 9 can be stably fixed to the outside of the support roller 8 through the extrusion force of the limiting plate 101 on the support roller 8.

[0023] Among them, a limiting hole 15 adapted to the bolt 102 is provided on the outer side of the limiting plate 9. The limiting hole 15 can limit the bolt 102 so that the bolt 102 is not easily bent and deformed during the tightening process.

[0024] When adjusting the level of the support roller 8, place the spirit level on the outside of the support roller 8 to observe whether the support roller 8 is in a horizontal state. If it is not in a horizontal state, loosen the second nut 14, loosen one of the limit columns 11, and observe whether the support roller 8 is in a horizontal state. When it is confirmed that the support roller 8 is in a horizontal state, tighten the other limit column 11, and tighten the second nut 14 on the limit column 11 respectively to complete the horizontal adjustment of the support roller 8.
