Assuming that the initial ink storage amount of the screen frame of the screen printer is (P 0) and the critical ink storage amount used for affecting the surface smoothness and chromatic aberration of a printed product is (P 1), the set amount (P) should satisfy P < (P 0- P1), so that the ink amount of the screen frame is always larger than the critical ink storage amount P 1.
Specifically, the set amount (P) =printing speed (V) ×printing time (T), wherein the printing speed (V) is the ink consumption amount of the screen printer per unit time.
The faster the printing speed, the higher the ink consumption of the screen printer per unit time.
Specifically, the lower end of the ink reservoir is provided with an ink discharge port, the discharge port is provided with a control valve which is opened or closed according to the instruction of a main control circuit, when the ink usage amount of the screen printer reaches a set amount (P), the main control circuit sends out an instruction to open the control valve on the ink reservoir, and when the ink addition amount of the ink reservoir reaches the set amount (P), the main control circuit sends out an instruction to close the control valve on the ink reservoir.
Specifically, the ink discharge speed (V 0) of the ink discharge port is constant, and the set amount (P) is in linear proportion to the discharge time (T 0) of the ink tank, i.e., p=v 0* T0, where V 0 refers to the amount of ink discharged per unit time of the ink discharge port of the ink tank.
Specifically, the main control circuit monitor and add black number of times (N), be provided with the alarm on the screen printer, alarm and main control circuit electric connection, when main control circuit monitors and add black number of times (N) and reach the preset number of times, the alarm sends out the alarm and reminds screen printer operating personnel to add printing ink to the ink reservoir.
Assuming that the initial ink storage amount of the ink storage device is (P 2), the initial ink storage amount of the ink storage device is (P 2) to satisfy P 2> V0* T0 ×n, that is, the ink in the ink storage device still has the remaining amount before the alarm is given out, so that the ink in the ink storage device is not used up before the alarm is given out.
The invention has the beneficial effects that: the automatic inking type screen printer solves the problems of uneven surface and chromatic aberration of screen printing products caused by different ink adding amounts and ink adding times of different operators, simultaneously satisfies continuous production of the screen printer, and improves production efficiency and product quality.
