Large-size platform type digital colored printer

Abstract

The invention discloses a large-size platform type digital colored printer comprising printing and inkjet printer heads, a stand base, a printing platform, moving mechanisms, a lifting mechanism, a console and a lathe bed computer numerical control circuit, wherein the printing and inkjet printer heads are arranged on the moving mechanisms arranged on two sides of the stand base; the moving mechanisms are connected and matched with a ball screw and a linear guide rail which are arranged on the stand base through a ball screw nut and a sliding block which are spanned on a walking beam of the stand base, and are driven by a driving motor to move back and forth; the lifting mechanism consists of a lifting motor arranged on the walking beam and lifters arranged at two ends of the walking beam; the lifting motor drives two screws which are arranged on the lifters and are in driving connection with a belt wheel through a circling belt and an intermediate belt wheel to simultaneously rotate so as to lift the printing and inkjet printer heads arranged on the lifting mechanism and drives the ball screw and the linear guide rail through a stepped motor for driving so as to drive the printing and inkjet printer heads to advance at uniform speed according to a printing instruction of an input computer for implementing digital colored spray painting and printing.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, relates to a large-scale digital printing equipment, in particular to a large-scale platform type digital color printer. Background technique [0002] The printing equipment in the prior art is usually divided into ordinary printers, flatbed printers and inkjet printers. These printing equipments are usually used to print text or patterns on the surface of paper or soft substrates. The lateral movement of the printing head and the longitudinal movement of the substrate, to realize the printing or jet printing of text or patterns point by line In addition, for large-scale rigid flat substrates or color patterns with embossed uneven surfaces, the existing equipment cannot realize the surface text. or pattern printing. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a large-scale platform type digital color printer, which has an advanced structure....

AI Technical Summary

Problems solved by technology

[0002] Printing equipment in the prior art is usually divided into ordinary printers, flatbed printers and inkjet printers. These printing equipment are usually used to print text or patterns on the surface of paper or soft substrates. The horizontal movement of the printing head and the vertical movement of the substrate realize the printing or printing of characters or patterns point by line. Due to the defects of low technical parameters, low precision, and unstable operation of the printing equipment, the printing or low-quality printed text or patterns, poor definition, color distortion of patterns, etc. In addition, for large hard flat substrates or painted patterns with embossed uneven surfaces, these existing devices cannot realize the surface text or pattern printing
