Problems solved by technology

Among them, the problem of real-time precise control of ink viscosity has not been solved well.
[0005] ① Ink viscosity control is inaccurate, and the error is large, which makes the color difference of the same product printed out larger
[0006] ② The adjustment and control is not timely, that is, the ink viscosity in high-speed printing is not adjusted or controlled in real time, and the scrap rate and defective rate of printed products are high
[0007] ③ People are prone to fatigue, and manual adjustment and control are difficult to ensure the consistency or stability of ink viscosity for a long time, which directly affects the stability of printing quality of batch products
[0009] ⑤The flow of skilled and experienced backbone employees will also directly affect product quality, which is too dependent on operating staff
[0010] ⑥ On the whole, the current manual method is costly, time-consuming and labor-intensive, and has low production efficiency

Embodiment Construction

[0038] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] Technical solutions:

[0040] 1. Basic functions and main parameters of ink viscosity controller.

[0041] Control: Microcomputer control system is adopted.

[0042] Display: digital or liquid crystal display.

[0043] Input indication: A light indicates that the sensor has output.

[0044] Output indication: Light B is on to indicate that the solenoid valve is open.

[0045] Valve cleaning button: When pressed, the solenoid valve will automatically open for T seconds (default value), and the ink pump will inhale solvent to clean the solenoid valve. The solenoid valve opening time can be set according to needs.

[0046] Setting button: Press this button to enter the parameter setting state.

[0047] Select button: In the parameter setting state, every time you press this button, the parameter code will increase by 1 (cycle).

Abstract

The invention relates to a computer-controlled device of printing ink glutinous viscosity comprising mainly a printing ink circulation pump, a computer-controlled apparatus, a solenoid valve, an air pressure sensor, an air-actuated pressure regulating valve and vapor separating arrangement. The invention can realize the substitution of the traditional artificial hand-operated regulation and control by the automatic computer control.

Description

technical field [0001] The invention belongs to the field of printing and packaging equipment, and more specifically, the ink viscosity computer controller is a kind of supporting equipment in the color printing machine. Background of the invention [0002] In the domestic printing and packaging industry, various domestic color printing machines are widely used. Among them, the problem of real-time and precise control of ink viscosity has not been solved well. In the printing process, whether the viscosity of the ink in the color printing machine is stable or not directly affects the printing quality of the surface color of the packaged product, that is, directly affects the economic benefits and even the survival of the enterprise. The viscosity control of printing ink mainly includes two tasks: first, presetting the viscosity of inks of various colors before printing; second, keeping the set or adjusted ink viscosity constant during the printing...
