Problems solved by technology

However, because the gray cloth is soft, when it is placed on the guide belt, the printing area and the pattern (that is, the position of the printing feature) are extremely prone to deformation, resulting in deviations when the inkjet equipment prints a specific pattern. The pattern of the gray cloth is positioned so that the inkjet device can spray ink on it according to the deformed pattern

Embodiment 1

[0053] A positioning digital printing machine, refer to figure 1, including a frame 1, the upper end of the frame 1 is provided with a guide belt 2, a slide rail 3 is arranged on the top of the guide belt 2 perpendicular to the direction of movement of the guide belt 2, and a spray nozzle sliding along the direction of the slide rail 3 is installed on the slide rail 3. Ink device 4, the both sides of frame 1 are all provided with the waste liquid recovery device 21 that matches with ink jet device 4, and ink jet device 4 stops at the top of waste liquid recovery device 21 when not moving, prevents the waste liquid recovery device 21 on ink jet device 4 Ink dripping contaminates conduction zone 2. The frame 1 is also provided with a guide roller assembly for winding gray cloth parallel to the direction of the slide rail 3 , and a controller 11 . In addition, in order to move the whole printing machine conveniently, universal wheels 67 are provided at the lower end of the frame...

Embodiment approach

[0079] Method A: Real-time rip method is used to perform real-time rip from the theoretical grid information of the printing area to the actual grid information of the printing area to obtain the inkjet information of the printing area;

[0080] Method B: Pre-process the theoretical image to obtain the prn file, and calculate the inkjet information of the actual grid in the printing area according to the theoretical grid information of the printing area;

[0081] Preferably, the present invention adopts B implementation mode;

[0082] Step S42: Obtain 1pass print data.

[0083] S5: Upload the obtained actual image data to the controller of the inkjet device as printing data;

[0084] Step S6: After the controller 11 of the inkjet device reads in the data of the actual image, start printing;

[0085] Step S7: The camera 68 continues to capture images of the next area, and this loops.

Embodiment 2

[0087] refer to Figure 10 The difference from Embodiment 1 is that a liquid level sensor 60 is provided on one side of the water tank 43, and a solenoid valve 66 is connected to the faucet. connect. refer to Figure 11 , the liquid level sensor 60 detects the height of the water level in the water tank 43, and outputs a detection signal

[0088] When the amplitude of its detection signal is less than the minimum threshold, the output start signal; the control panel 61 includes a first comparator 63 pieces, the first comparator 63 pieces include a minimum threshold generating circuit 62 and a first comparator 63, the liquid level The sensor 60 outputs a liquid level signal to the inverting input terminal of the first comparator 63, and the minimum threshold value is input to the non-inverting input terminal of the first comparator 63. When the detection signal is less than the minimum threshold value, the output terminal of the first comparator 63 outputs a start signal To ...

Abstract

The invention discloses a digital printing machine positioning method. The method comprises the following steps: a camera takes an image of a designated grey cloth and the image is uploaded to a computer; an image recognition technology is used to obtain the printing feature position of the actual image; contrast is carried out on the acquired printing feature position of the actual image and a related printing feature position of a theoretical image, and the actual grid information of a printing area is calculated; according to the obtained actual grid information of the printing area and corresponding theoretical grid information, data of the actual image are calculated again, and the data are uploaded to a controller of inkjet equipment; the controller of the inkjet equipment reads thedata of the actual image, and printing is started; and the camera continuously takes an image of a next area, and such circulation is performed. The pattern of the grey cloth is photographed by the camera, the pattern is inputted to the computer, the actual grey cloth pattern is contrasted with a theoretical pattern, the accurate inkjet information is calculated, and grey cloth printing is more accurate; and besides, the method is applicable to a grey cloth with deformation, and the whole equipment is thus more universal.

Description
