Printhead including coanda catcher with grooved radius |
摘要 |
A printhead includes a jetting module, deflection mechanism, and catcher. The jetting module includes a linear array of nozzles having a pitch and extending along a length of the jetting module. The jetting module is configured to form drops travelling along a first path from liquid jets emitted from the nozzles. The deflection mechanism is configured to cause selected drops to deviate from the first path and begin travelling along a second path. The catcher, positioned to intercept drops travelling along one of the first and second paths, includes a drop contact surface and a liquid removal conduit connected in fluid communication by a Coanda surface including a radial surface having an array of grooves extending in the same direction as that of the nozzle array. For a given groove, the groove is positioned at an angle relative to the drop contact surface. |

1. A printhead comprising:
a jetting module including a linear array of nozzles extending in a direction along a length of the jetting module, the jetting module being configured to form liquid drops travelling along a first path from a plurality of liquid jets emitted from the nozzles; a deflection mechanism configured to cause selected liquid drops formed by the jetting module to deviate from the first path and begin travelling along a second path; and a catcher positioned to intercept liquid drops travelling along one of the first path and the second path, the catcher including a drop contact surface and a liquid removal conduit connected in fluid communication with each other by a catcher surface including a radial surface having an array of grooves, the array of grooves extending in the same direction as that of the linear array of nozzles, wherein for a given groove of the plurality of grooves, the groove is positioned at an angle relative to the drop contact surface. |
