System for cleaning cart drive components in three-dimensional object printing systems

摘要

A cart that helps eliminate contaminants from a printing system with a rail support track includes a platform, a first bearing, and a first blade. The first bearing is operatively connected to the platform, and is positioned and configured to roll along a first cylindrical rail of a rail support track of a printing system to enable the platform to move along the first cylindrical rail. The first blade has a leading edge oriented at an acute angle relative to a curved surface of the first cylindrical rail, and is configured to engage the curved surface to remove contaminant as the cart moves along the first cylindrical rail.

主权项

1. A cart that moves through in a printing system, the cart comprising:
a platform; a first bearing operatively connected to the platform, the first bearing being configured to roll along a first cylindrical rail of the printing system to enable the platform to move along the first cylindrical rail; and a first blade that is mounted to the platform and positioned to engage a curved surface of the first cylindrical rail as the first bearing rolls along the first cylindrical rail, the first blade having a leading edge that is oriented at an acute angle relative to the curved surface of the first cylindrical rail and the leading edge of the first blade being a curved edge with a radius substantially similar to a radius of the first cylindrical rail to enable the first blade to remove contaminant from the first cylindrical rail, the first blade having a shape of a radial section of a truncated cone with a radius of the first blade increasing with distance from the leading edge of the first blade.
