Abstract

This scraping blade, roll-cleaning apparatus includes a cleaning blade whose pivotal mounting insures uniform contact with the roll, even though the blade's longitudinal pivot axis may not be exactly parallel to the roll's longitudinal axis.

Self Aligning Roll Scraper

This scraping blade, roll-cleaning apparatus includes a cleaning blade whose pivotal mounting insures uniform contact with the roll, even though the blade's longitudinal pivot axis may not be exactly parallel to the roll's longitudinal axis.

Fig. 1 is a side view of the cleaning apparatus, whereas Fig. 2 is a top view thereof. Cleaning blade 10 includes a reentrant scraping portion 11 which engages the surface of roll 12, as the roll rotates clockwise. The blade 10 includes a pair of side supports which extend upward to support shaft 18 and a spring engaging tab.

The blade is pivoted on axis 13, generally parallel to the roll's axis. Spring 14 (not shown in Fig. 2) force biases the blade 10 into the roll's surface. The blade is carried by block member 15. This member traverses back and forth along the length of the roll 12, driven by double-helix leadscrew 16 and guide rod 17.

The pivot axis of blade 10 is defined by shaft 18 which is integrally carried by the blade. This shaft is supported by mounting plate 19. Plate 19 includes a pair of upstanding metal tabs 20 and 21 which engage the shaft 18 in the center thereof. As a result, shaft 18 is free to pivot about its axis 13, as well as being free to pivot about tabs 20 and 21 to change the shaft's axial direction. Plate 19 also includes two upstanding tabs 22 and 23 which engage portions 24 and 25 of the cleaning blade, to prevent axial displacement of the blade 10.

Shaft 18 is held wi...
