Description

Follow-up polishing device for repairing excircle of rubber roller Technical Field The invention relates to the technical field of rubber roller polishing, in particular to a follow-up polishing device for repairing an excircle of a rubber roller. Background The rubber roller is a functional roller component in the core of industrial production, generally takes high-strength metal as a rigid mandrel, and the outer layer is coated with natural rubber and synthetic rubber and is manufactured into cylindrical components with different hardness and different surface structures through a vulcanization process, so that the rubber roller is widely applied to a plurality of industrial fields such as printing, papermaking, textile, rubber and plastic processing, metallurgy, packaging and the like, bears key processes such as material conveying, calendaring, coating, laminating, traction, embossing and the like, and has the performance indexes such as geometric precision, roundness, surface roughness, coaxiality and the like of the outer round surface, so that the stability of the production process, the product processing precision and the quality of a finished product are determined, and performance attenuation is caused by the problems such as abrasion, corrosion, deformation and the like in long-term operation, so that the surface precision and the working performance of the rubber roller are recovered through excircle repairing and polishing treatment, and the rubber roller is a key vulnerable part for guaranteeing the high-efficiency and stable operation of an industrial production line. At present, in the rubber roller polishing process, the rigidity continuous contact of emery wheel and rubber roller can produce continuous side direction conflict power to soft rubber roller body, very easily cause the local deformation of roller body, the damage such as roller removal even burn foaming, can't satisfy the repair requirement of high accuracy rubber roller, and the viscidity rubber piece that produces of polishing not only splashes pollution operation environment everywhere, adhere to the inside stability that influences of equipment, still easily block up the emery wheel hole and cause emery wheel passivation, polishing efficiency decline sharply, generally lack integrated piece collection and emery wheel automatically cleaning mechanism, need frequent shut down to carry out manual cleaning, reduce the prosthetic overall efficiency of rubber roller by a wide margin, increase the manual maintenance cost, still lead to technology continuity poor because of the operation interruption, be difficult to adapt to modern industrial production line to high accuracy, low damage, the continuous prosthetic core demand. According to the technical defects, the rubber roller centering clamping is realized through double fixation of the conical grooves and the clamping claws, intermittent contact polishing of the triangular arc-shaped sand blocks of the grinding wheel is combined, deformation damage of the rubber roller is avoided, low-damage follow-up polishing is realized, meanwhile, a negative pressure collecting and self-cleaning mechanism is integrated, polishing scraps are collected in a directional mode, the grinding wheel is reversely purged through cleaning airflow, full-automatic sand cleaning and heat dissipation are realized, polishing, chip removal and sand cleaning integrated treatment is formed, polishing quality is guaranteed to be stable, and operating efficiency and service life of the grinding wheel are improved.
