[0032] Specifically, the number of camera 8 is multiple and is in matrix distribution;The number of camera 8 is set according to specific demand.

[0033] The camera processor 7 and the camera 8 realize data transmission through a multi-line data interface by using a TCP protocol (see Chinese Utility Model Patent CN214673325U for details).

[0034] The camera 8 adopts a DALSA PC-30-04K80 color line array scanning camera.

[0035] Specifically, the control system comprises a data analyzer 9, a control host 10 and a master controller 11, the data analyzer 9 is positioned and connected at the top of the camera processor 7 and is electrically connected with the camera processor 7, the control host 10 and the master controller 11 are connected at the upper two ends in the detection tank 6, the data analyzer 9 is electrically connected with the control host 10, the ink adding mechanism 4 and the control panel 5 are electrically connected with the control host 10 through the master controller 11; the data analyzer 9 receives information from the camera processor 7 and pre-processes it, and then transmits the processing result to the control host 10, the control host 10 calculates the ink supply amount after receiving the information, and controls the ink adding mechanism 4 to supply ink.

[0036] First, the original picture is read and loaded by using image processing software such as OpenCV, and then it is converted from BGR color space to HSV color space to utilize the separation characteristics of HSV in three dimensions of hue, saturation and lightness to define the color threshold range more flexibly. Then, for each color to be calculated, the HSV threshold is set and a binary mask is generated by the inRange() function, where white pixels represent areas that meet the color condition. The number of white pixels in the mask is counted by using the countNonZero() function, and the color area, i.e. the actual area covered by ink, is obtained.

[0037] The ink consumption of a printed product = actual area covered by ink × ink thickness × ink specific gravity, the ink specific gravity can be obtained from the supplier, and the thickness is set according to actual needs (the ink thickness printed by different devices is different, which is obtained through the experience of workers).

[0041] The control host 10 controls the ink pump 13 to supply ink according to the calculated ink consumption, and detects and adjusts the volume of the pumped ink through the flow monitor 18, so as to realize accurate ink supply.

[0042] Specifically, as shown in the figure, Fig. 3 The ink supply mechanism 4 includes an ink storage tank 12, an ink pump 13, an ink pipe 14, a flow monitor 18, a connecting head 19 and a fixing member 20. The ink pump 13 is arranged on the inner bottom surface of the ink storage tank 12. The output end of the ink pump 13 is connected with one end of the ink pipe 14. The other end of the ink pipe 14 is connected with the connecting head 19 after penetrating through the ink storage tank 12. The connecting head 19 is installed on the side wall of the printing machine body 1 through the fixing member 20, so that the ink pipe 14 is connected with the ink loading device of the printing machine body 1 (the connecting head 19 is connected with the ink cartridge of the printing machine body 1. The ink loading device (not shown) is beside the side wall. The design only needs to supply ink to the ink loading device. There are pipelines and devices in the screen printing machine for supplying ink from the ink cartridge to the printing workbench). The flow monitor 18 is installed on one side of the ink pipe 14 close to the fixing member 20. The ink pump 13 pumps the ink in the ink storage tank 12, and then transmits the ink to the inside of the printing machine body 1 through the ink pipe 14. In this process, the flow monitor 18 monitors the ink flow in the ink pipe 14 in real time.

[0043] Specifically, the top of the ink supply mechanism 4 is further provided with a heating mechanism. The heating mechanism includes a heating tank 15, a heater 16 and a heating pipe 17.

[0044] The use process of the utility model is as follows:

[0045] The starting device is used to place the file to be scanned into the detection slot 6, the camera 8 scans the pattern area and is transmitted into the camera processor 7, the camera processor 7 returns the collected pictures to the linux host, adjusts the gain and offset of each color pixel to ensure the scanning accuracy, and transmits the scanning result to the data analyzer 9 for data preprocessing (the preprocessing is specifically: calculating the actual area of ink coverage), the data analyzer 9 transmits the data processing result to the control host 10, the control host 10 calculates according to the received data, and obtains the required ink supply amount (specifically: the ink consumption of a printed product = the actual area of ink coverage x the thickness of ink x the specific gravity of ink), and the control host 10 controls the ink adding mechanism 4 to supply ink according to the calculation result; in this process, the matrix camera 8 scans the pattern in real time, and the data is analyzed through the control system to obtain the real-time required ink supply amount (specifically: the real-time required ink supply amount = the actual area of ink coverage currently scanned by the matrix camera 8 x the thickness of ink x the specific gravity of ink), the control host 10 controls the ink adding mechanism 4 to supply ink, improves the efficiency of ink supply, avoids poor printing accuracy caused by too fast or too slow ink supply, and improves the printing accuracy and efficiency;

[0046] When supplying ink, the ink pump 13 draws the ink inside the ink storage tank 12, and then transmits it to the inside of the printing machine body 1 through the ink pipe 14, in this process, the flow monitor 18 monitors the flow inside the ink pipe 14 in real time, and the control host 10 can more accurately control the ink output by controlling the working state of the ink pump 13, thereby improving the printing efficiency;

[0047] The flow monitor 18 can calculate the amount of liquid flowing in, and after reaching the amount set by the control host 10, feedback the data to the control host 10, and the control host 10 sends a stop signal to the ink pump 13 to stop adding ink.

[0048] When the temperature is lower than the preset temperature, the control host 10 controls the heating device to start, the heater 16 heats the liquid inside the heating pipe 17, the heating pipe 17 is arranged outside the ink pipe 14 and heats the ink inside the pipe, so as to prevent the ink from being cooled and blocked, thereby ensuring normal ink supply.

[0049] The printing method of the screen printing machine is to apply ink to the screen, and to print by using the principle that the screen holes of the text part of the screen printing plate are transparent to ink and the screen holes of the non-text part are not transparent to ink; that is to say, only the ink printed on the printed matter is consumed ink, and the rest of the ink is circulating on the screen printing plate and is not consumed; therefore, the preset circulating ink amount is supplied by calculating the required ink amount, so as to meet the accurate on-demand ink supply.
