Printing trolley of multi-nozzle digital pyrography printer

Abstract

The utility model provides the printing trolley of the multi-nozzle digital pyrography printer, and the printing trolley of the multi-nozzle digital pyrography printer moves left and right to drive a plurality of nozzles to move so as to complete printing operation. When the printing trolley exceeds the fixed route, the anti-collision mechanism makes contact with the external supporting frame, the anti-collision mechanism can buffer the impact force between the printing trolley and the external supporting frame, and therefore the printing trolley is protected. Specifically, the fixing plate abuts against an external supporting frame, and the friction plate abuts against a friction pad on the external supporting frame in a friction mode, so that the speed of the printing trolley of the multi-nozzle digital pyrography printer is reduced and stopped rapidly. The fixed plate drives the rotating plate to rotate through the friction plate, and the rotating plate extrudes the compression spring in the rotating process. And the compression spring buffers the impact force on the fixing plate. And the nozzle bearing mechanism is well protected. The printing trolley of the multi-nozzle digital pyrography printer can bear a plurality of printing nozzles, so that the requirement of multi-color printing can be met.
