Complete equipment applied to digital 3D printing

Abstract

The invention provides complete equipment applied to digital 3D printing. The complete equipment comprises a rack, a machine base, a foot pad, a longitudinal guide rail, a transverse guide rail, a flat plate, a spray head driving mechanism, a wrinkle removing mechanism, flat plate positioning mechanisms, flat plate pressing mechanisms and a drying mechanism, and the rack is arranged on the top surface of the machine base. The foot pad is arranged on the bottom surface of the machine base. The longitudinal guide rail and the transverse guide rail are arranged on the inner side of the rack. Theflat plates are slidably arranged on the transverse guide rail. The spray head driving mechanism is arranged on the top surface of the rack in a crossing manner. The wrinkle removing mechanism and therack can be arranged in a sliding manner through the driving mechanism. The flat plate positioning mechanisms are arranged on the side wall of one end of each flat plate. The flat plate pressing mechanisms are arranged on the two sides of each flat plate. The drying mechanism is arranged on the side wall surface of the spray head driving mechanism. The wrinkle removing process is high in efficiency, printed matters can be firmly fixed to the surfaces of the flat plates, stable operation of the printing process is guaranteed, the equipment has high drying efficiency, and the printing process is high in efficiency.

Description

technical field [0001] The invention relates to the field of digital printing equipment, in particular to a complete set of equipment applied to digital 3D printing. Background technique [0002] The digital direct inkjet machine breaks through the bottleneck of digital printing technology, and realizes a real one-time printing, no need for plate making, and full-color image completion at one time. The digital direct printing machine can print a variety of patterns, including flat patterns, 3D patterns, etc. for direct printing. The digital direct injection machine has a variety of structural forms. One of the structural forms of the digital direct injection machine is the digital direct injection machine of the flat printing type. The nozzle of the sprayer is suspended above multiple flat plates through the truss, and the nozzle of the digital direct printing machine is driven by the lateral displacement through the rails on both sides, and the vertical displacement of the...

AI Technical Summary

Problems solved by technology

There are the following defects in the existing structure: 1) When the digital direct-injection machine is used, the printed matter is placed on the flat plate for display, and the nozzle of the digital direct-injection machine is sprayed horizontally to allow the surface to be approved, which requires the printed matter to have High flatness, the deviation of the pattern caused by wrinkles during the printing process, directly affects the process of direct injection, resulting in the scrapping of printed matter

2) When setting the items to be printed, by directly contacting the items with the flat plate, no good fixation between the printed items and the flat plate is formed, and the items with small mass are subject to the reciprocating action of the nozzle, and the items flow easily with the airflow. Offset occurs, resulting in errors in printing results; and it is impossible to achieve uniform positioning of printed items on the surface of the tablet

3) In order to quickly dry the ink printed on the surface of the printed matter, in the prior art, there is a drying device for the digital direct injection machine, and the drying device is arranged on one side of the nozzle mechanism. After printing, the drying device is moved to the surface of the printed matter for alignment, lifting and drying process. The preparation efficiency of the process is low, and it is not suitable for large-scale batch production; the surface drying efficiency of the printed matter in the drying device is low
