Abstract

The invention discloses an anti-accretion strengthening type sink roller. The sink roller comprises a roller shaft, a roller cylinder and end covers; the roller shaft and the end covers are arranged on the two sides of the roller cylinder in a mirror symmetry mode; the end covers are fixedly connected between the roller shaft and the roller cylinder and at the two ends of the roller cylinder; a supporting mechanism is arranged between the end covers at the two ends in the roller cylinder; the supporting mechanism comprises a thin-wall elastic cylinder, adjusting bolts and movable rings at thetwo ends of the thin-wall elastic cylinder; the thin-wall elastic cylinder is distributed in the axis direction of the roller cylinder, and the two ends of the thin-wall elastic cylinder abut againstthe inner sides of the movable rings; the adjusting bolts are in threaded connection with the end covers at the two ends, and one end of each adjusting bolt penetrates through the corresponding end cover and abuts against the outer side of the corresponding movable ring. The sink roller is further characterized in that a groove is formed in the inner side of each movable ring, and the ends of thethin-wall elastic cylinder are embedded into the grooves in the inner sides of the movable rings; a wear-resistant layer is arranged on the outer wall of the roller cylinder; spiral grooves opposite in rotation direction are formed in the surface of the wear-resistant layer of the roller cylinder, and the bottoms of the spiral grooves are both in an arc shape. The sink roller is high in structurestrength, small in deformation and long in service life, and completely solves the problem of accretion on the surface of the roller.

Description

technical field [0001] The invention relates to heat treatment equipment, in particular to a sinking roll. Background technique [0002] The sinking roll is one of the important equipment on the hot-dip galvanizing line. It is made of stainless steel. During production, the sinking roll needs to be immersed in the molten zinc liquid and rotate with the drag of the galvanized sheet. Sinking rollers are generally hollow structures with poor intermediate strength and are easily deformed, and eccentric wear occurs during the production process, which shortens their service life. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes an anti-nodulation reinforced sinking roller which significantly improves the strength of the sinking roller, reduces deformation, completely solves the problem of nodules formed on the surface of the roller, and has a long service life. [0004] The present invention achieves technical goals...
