Double-nozzle integrated digital double-sided inkjet printer and inkjet printing method thereof

Abstract

The invention belongs to the technical field of inkjet printing equipment, and particularly relates to a double-nozzle integrated digital double-sided inkjet printer and an inkjet printing method thereof. The inkjet printer comprises an inkjet part and a transmission part, wherein the inkjet part comprises an integrated inkjet cross beam and two inkjet mechanisms; and the two inkjet mechanisms comprise two inkjet rails arranged on the integrated inkjet cross beam, two inkjet trolleys arranged on the two inkjet rails and capable of reciprocating, two spray nozzles arranged on the two inkjet trolleys and two inkjet platforms arranged below the two inkjet trolleys. The inkjet printer has the characteristics of compact in structure, reasonable in design and convenient to install.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing equipment, and in particular relates to an integrated digital double-sided inkjet printer with double nozzles and an inkjet printing method thereof. Background technique [0002] Commercial publicity can use many methods. As an important means of outdoor publicity, businesses often install light boxes or billboards printed with design patterns and texts outdoors, so that people can see and know them well in their lives and work. In the production of light boxes and billboards, synthetic resin materials, PVC materials, etc. are generally used as base materials, and at the same time, prominent text, unique pattern design, and bright colors are required. [0003] Single-sided inkjet printers generally have a control unit, an inkjet printing unit, and a base material transmission unit. When working, people input the designed patterns, text, etc. into the control unit, and the control unit tran...

AI Technical Summary

Problems solved by technology

However, the use of single-sided inkjet printers to produce light boxes and billboards has the following disadvantages: generally, only one side of the substrate can be inkjet-painted. It is labor-intensive and time-consuming, and the mirror-symmetric images of the front inkjet and the reverse inkjet often cannot be accurately positioned and completely matched, and the visual effect is poor.

[0010] Another defect of the above-mentioned double-sided inkjet printer is that in order to realize single-sided and double-sided printing, it is necessary to set up to 15 rollers such as a plurality of driving rollers, cloth receiving rollers (or cloth releasing rollers), cloth clamping rollers, and cloth guide rollers. When spraying, the canvas needs to pass through multiple S-shaped shapes, or the canvas (substrate) needs to pass through the spray painting platform of the spray painting department from the lower outside of the spray painting department, around the upper, left, and right sides of the spray painting department. , go out from the outer side of the inkjet section, detour directly under another inkjet section, and collect the cloth outside the lower side; or the canvas (substrate) is drawn out from the outer side of a set of inkjet sections, and gradually approaches the side of the inkjet section After being sprayed by the spraying part, it is derived from the other outside of the spraying part, and gradually approaches the outside of the other spraying part from the distance of the other spraying part. Outer export, cloth receiving

It can be seen that the wiring threads in the prior art are long and complicated, and the required machinery and equipment are large in size and occupy a large space

[0011] To sum up, the double-sided printers in the prior art have the following defects: the two groups of inkjet printing units are independent of each other, the equipment is large in size and takes up a lot of space, and the volume of the entire equipment is about 5-20 times the volume of a single set of inkjet divisions, and The corresponding parts of the two sets of inkjet printing departments must be designed, produced, and installed exactly the same, which requires high precision in equipment manufacturing and installation, which increases the cost

However, in this technology, the double nozzles are arranged side by side and fixed on the double nozzle bottom plate. This structure can only be used for 3D printers. When it is working, the substrate is moved to the printing platform, and hot-melt materials of different colors pass through the dual nozzles and are heated. Extrusion performs two-color printing on the printing substrate; but this technology cannot be applied to the double-sided printer in the subject of the patent, because the duplex printer in the subject of the patent is designed to print the same pattern on the front and back of the same substrate, and the two sides The function of each nozzle is to print the front and back of the same substrate, which requires that when the substrate passes through one nozzle, the front of the substrate is facing the nozzle, and when the substrate passes through the other nozzle, it is the reverse side of the substrate. Due to the continuity of the base material, two nozzles cannot be fixed side by side on the same base plate
