Strengthened-type sink roller capable of preventing build-up edge

Abstract

The invention discloses a strengthened-type sink roller capable of preventing build-up edge. The strengthened-type sink roller comprises roller shafts, a roller cylinder and end covers, wherein the roller shafts and the end covers are arranged at both sides of the roller cylinder in a mirror symmetry manner; each end cover is fixedly connected between the roller shafts and the roller cylinder and at both ends of the roller cylinder; a support mechanism is arranged between the end covers located at both ends of the roller cylinder and comprises thin-walled flexible cylinders, adjusting bolts and movable rings located at both ends of the thin-walled flexible cylinders; the thin-walled flexible cylinders are distributed along the axis of the roller cylinder and has both ends propping against the inner sides of the movable rings; the adjusting bolts are in threaded connection with the end covers located at both ends of the roller cylinder, and one end of each adjusting bolt penetrates through the end covers and props against the outer side of the corresponding movable ring; the strengthened-type sink roller is characterized in that grooves are formed in the inner side of each movable ring and the end parts of the thin-walled flexible cylinders are embedded inside the grooves formed in the inner side of each movable ring; the outer wall of the roller cylinder is provided with a wear-resistant layer; spiral grooves having opposite rotation directions are formed in the surface of the wear-resistant layer of the roller cylinder; and the bottoms of the spiral grooves are of circular-arc shapes. The strengthened-type sink roller has the advantages of high structural strength, small deformation, long service life and capability of thoroughly solving the problem of formation of build-up edge 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...
