Embodiment 1
[0027] A shielding oil pad printing device for a metallized safety film, the structure of which is as follows figure 2 As shown, it includes an oil storage tank 1, an oil pump 3, a stepping motor 4, an oil pipe 7, a heating resistor 8, a ceramic roller 10, a patterned roller 11, a connecting pipe and a base film stepping motor; the oil storage tank 1 is used for Store the shielding oil at normal temperature; it is connected to the oil pump 3 through the connecting pipe, and the oil pump 3 is driven by the stepping motor 4. The stepping motor 4 has a microprocessor controller to control the speed of the stepping motor 4. The stepping motor The rotation speed of 4 is equal to the rotation speed of the oil pump 3; the oil pipe 7 includes an oil pipe inlet 6 and an oil pipe evaporation port 9, the oil pump 3 is connected to the oil pipe inlet 6 of the oil pipe 7 through a connecting pipe, and the heating resistor 8 is used for heating The oil pipe 7 and the pump pass through the ...
Embodiment 2
[0029] A shielding oil pad printing method of a metallized security film, which utilizes the shielding oil pad printing device of the metallized security film of embodiment 1, comprising the following steps:
[0030] a) storing the shielding oil in the oil storage tank 1;
[0031]b) Calculate the oil demand L per 10,000 square meters according to the specifications of the base film to be printed, and calculate the running time 10,000 / V per 10,000 meters according to the running speed V) of the base film to be printed, so as to obtain the oil to be printed The oil consumption LV / 10000 required by the base film per minute;
[0032] c) At the same time, according to the diameter of the connecting pipe between the oil storage tank 1 and the oil pump 3, calculate the oil pumping capacity L1 per revolution of the oil pump 3, thereby setting the stepper motor 4 through the microprocessor controller of the stepper motor 4 The speed V2=LV / (10000L1);
[0033] d) Start the stepping mot...
Embodiment 3
[0040] A shielding oil pad printing method for a metallized safety film. The specific process is that an oil pump 3 controlled by a stepping motor 4 containing a microprocessor controller passes through a silicone tube with a fixed diameter to feed the shielding oil in the oil tank 1 through the oil pipe. The oil port 6 reaches the inner cavity of the oil pipe 7. For example, the oil demand per 10,000 square meters of a film product to be printed is 4.8mL, and the running speed of the base film to be printed is 10m / s. The time is 16.7min, so the oil consumption per minute is about 0.2874ml / min (that is, 4.8ml / 16.7min); at the same time, the oil pumping capacity of the oil pump 3 calculated according to the inner diameter of the silicone tube is 0.02ml / rev, and the step The rotating speed of the feed motor 4 can be set to about 14.37 turns / min (ie 0.2874 / 0.02). It can be seen that the speed of the stepping motor 4 can be calculated according to the requirements of the oil deman...
