Problems solved by technology

[0003] Among them, the tile-type roller skin with a flat bottom surface and the polyhedron roller shaft are connected by precision-machined bolts, which cannot effectively prevent loosening, and cannot eliminate the misalignment of the roller extrusion surface caused by machining errors
[0004] The tile-type roller skin with arc bottom surface is connected with the cylindrical roller shaft by a conical ring, and the disassembly process requires special tools to assist, and is relatively cumbersome
[0005] Both existing structures have relatively strict requirements on the shape tolerance of the contact surface between the roller shaft and the roller skin, and the shape and position tolerance of the keyway.

Abstract

The invention discloses a pad type roller skin structure of a medium-pressure roller press. The pad type roller skin structure of the medium-pressure roller press comprises pad type roller skins, a roller skin locking ring, roller skin locking threaded rods, roller skin keys and a roller shaft. Each pad type roller skin is provided with a fan-shaped section. The outer circular arc face of each fanshape is provided with a plurality of pressing die die cavities. The lower sides of the two side faces of each fan shape are provided with stepped grooves. The two ends of each pad type roller skin are provided with wedge-shaped flanges. Each wedge-shaped flange is provided with a first bolt hole. The roller skin locking ring is provided with a conical inner circular face. The end face of the roller skin locking ring is provided with a plurality of through holes and threaded holes. The roller skin keys are provided with second bolt holes. The roller shaft is provided with an annular groove. The annular groove is internally provided with a plurality of threaded holes and key grooves. The stepped grooves of the two pad type roller skins can be spliced into a U-shaped groove. The multiple pad type roller skins can be spliced into one complete circular ring. The pad type roller skin structure of the medium-pressure roller press can lower the assembly and disassembly difficulty of the roller skins, reduces roller pressing face dislocation caused by machining errors, lowers machining difficulty and guarantees the overall structure to be firm and reliable.

Description

technical field [0001] The invention relates to a component of a medium-pressure roller press, in particular to a pad-type roller skin structure of the medium-pressure roller press. Background technique [0002] The existing tile-type roll skin structure of the medium-pressure roller press is usually divided into two types: a tile-type roll skin with a flat bottom surface and a tile-type roll skin with an arc-shaped bottom surface, and each roll skin bottom has 1 one or more keyways. [0003] The tile-type roller skin with a flat bottom surface is connected with the polyhedron roller shaft with precision-machined bolts, which cannot effectively prevent loosening, and cannot eliminate the misalignment of the roller extrusion surface caused by machining errors. [0004] The tile-type roller skin with arc-shaped bottom surface is connected with the cylindrical roller shaft by a conical ring, and the disassembly process requires the assistance of special tools and is relatively...
