Problems solved by technology

[0005] Therefore, after the digital inkjet printing machine has been running for a period of time, the vibration of the digital inkjet printing machine will cause the position of the camera to deviate. The sub-block shooting area is not on the same straight line or the overlapping parts of the rectangular sub-block shooting area of ​​the camera are shifted, which will cause the overall image of the printing medium formed by splicing after shooting by several cameras to be stretched or deformed, reducing the digital inkjet printing machine. printing accuracy

Among them, the frame 1 is provided with a cloth guide roller assembly 5 for winding the printing medium on one side of the conveying device 2, and the frame 1 is provided with a cloth roller assembly for winding and printing on the other side of the conveying device 2 6.

[0054] Wherein, the conveying device 2 has a feeding area s and a printing area p. The inkjet printing device 3 is arranged above the printing area p of the conveying device 2 , and the camera device 4 is arranged above the feeding region s o...

Embodiment 2

[0067] combine figure 2 with image 3 As shown, the beam 41 is provided with a moving part 8 for adjusting the position of the camera 42 . In this embodiment, the moving part 8 includes a moving groove 81 arranged along the length direction of the crossbeam 41. An L-shaped bracket 82 is slidably installed in the moving groove 81. One end of the bracket 82 is provided with a first slide groove 83, and the other end of the bracket 82 is opened. There is a second chute 84, one end of the bracket 82 passes through the first chute 83 through the first fastener 85 and is connected in the moving groove 81, and the other end of the bracket 82 passes through the second chute through the second fastener 86 84 is connected on the adjustment assembly 43. In this embodiment, bolts are used for the first fastener 85 and the second fastener 86 .

[0068] In the technical solution of the present invention, each digital printing system needs to adapt to the needs of jet printing media of d...

Embodiment 3

[0070] A camera grid positioning method using the digital printing system described in the above embodiment, comprising the following steps:

[0071] S1, arrange the positioning medium on the feeding area s of the conveying device 2, several cameras 42 photograph the positioning medium to form image information and transmit it to the computer, and the computer calls the grid line template to match the image information of the positioning medium;

[0072] S2, the conveying device 2 conveys the positioning medium to the printing area p, uses the inkjet printing device 3 to print the grid line template on the positioning medium, and the conveying device 2 returns the printed positioning medium to the feeding area s;

[0073] S3, several cameras 42 shoot the positioning medium again to form image information and transmit it to the computer, and the computer establishes a fiducial positioning mark 7 in the center of the shooting area of ​​each camera 42 to display in the image infor...

Abstract

The invention discloses a digital printing system and a camera grid positioning method thereof; the digital printing system comprises a conveying device, an ink-jet printing device and a camera device; the ink-jet printing device is arranged above a jet printing area of the conveying device; the camera device is arranged above a feeding area of the conveying device, connected with a computer, andcomprises a crossbeam; the camera device also comprises a plurality of cameras arranged on the crossbeam side by side via adjusting members; the camera is used for gathering image information of a positioning medium in the feeding area; the computer is used for receiving the image information so as to build reference localizers in the center of each camera shooting area; each camera can carry outthree-shaft swing via the adjusting member so as to adjust the position of the reference localizer. The method enables the shooting area of each camera to be on the same straight line, and the shooting area intervals of two adjacent cameras are equal, thus effectively improving the printing precision of the following ink-jet printing device.

Description

technical field [0001] The invention relates to the field of printing machines, in particular to a digital printing system and a camera grid positioning method thereof. Background technique [0002] Digital inkjet printing technology is a high-tech product integrating machinery, computer electronic information technology and gradually formed with the continuous development of computer technology. The emergence and continuous improvement of this technology has brought a brand new concept to the textile printing and dyeing industry. Its advanced production principles and methods have brought an unprecedented development opportunity to textile printing and dyeing. It will gradually replace the traditional printing method and become The main equipment for textile printing. [0003] Existing digital inkjet printing machines include a frame, a conveying device arranged on the frame, an inkjet printing device and several cameras, and several cameras are arranged side by side above...
