An automatic diluent adding device in precision industrial screen printing

Abstract

The invention discloses a precision industrial silk-screen printing instrument and particularly relates to an automatic diluent adding instrument used in precision industrial silk-screen printing. With the automatic diluent adding instrument used in precision industrial silk-screen printing, the timed cost is effectively saved, the adding precision is improved, and the processing technology is stabilized. The automatic diluent adding instrument comprises a miniature mist air spray nozzle, a gas-liquid electromagnetic valve, a PLC (Programmable Logic Controller), a water pump, an intermediate relay and a container tank, wherein the container tank is used for storing a diluent, a liquid inlet, an air inlet and a spray opening are formed in the miniature mist air spray nozzle, the gas-liquid electromagnetic valve comprises a liquid valve assembly and a gas valve assembly, and the intermediate relay is used for calculating sprinkling time and spaced time; the container tank is communicated with the liquid inlet through the water pump, the liquid valve assembly is arranged between the water pump and the liquid inlet, and the air inlet is communicated with the gas valve assembly; the PLC is connected with the intermediate relay, the water pump, the liquid valve assembly and the gas valve assembly.

Description

technical field [0001] The invention relates to the technical field of precision industrial screen printing equipment, in particular to an automatic diluent adding instrument in precision industrial screen printing. Background technique [0002] As we all know, diluent needs to be added in the process of precision industrial screen printing, but the automatic adding process cannot be realized in the existing technology, which is specifically reflected in: 1) Every day when each equipment is printed, a technician needs to recycle the ink to add diluent and then return 2) Since the amount of addition must be accurate to 1ml, the accuracy of manual addition cannot reach 1ml, and the quality of screen printing will be directly affected by adding more or less thinner, resulting in the ink thickness after printing. Process requirements, resulting in waste of cost materials. Contents of the invention [0003] In order to solve the above technical problems, the present invention ...
