Principle and use of character inkjet printer

Working principle

The working principle of the character inkjet printer: the ink passes through the ink pipeline from the ink tank, adjusts the pressure, viscosity, and enters the spray gun. As the pressure continues, the ink is ejected from the nozzle, and when the ink passes through the nozzle, it is under pressure. The action of the transistor breaks into a series of continuous ink droplets with equal spacing and the same size, and the jetted ink flow continues to move downward and passes through the charging electrode to be charged, and the ink droplet is separated from the ink line in the charging electrode. A certain voltage is applied to the charging electrode. When the ink droplet is separated from the conductive ink line, it will instantly carry a negative charge proportional to the voltage applied to the charging electrode. By changing the voltage frequency of the charging electrode to make it the same as the frequency of ink droplets breaking, each ink droplet can be charged with a predetermined negative charge. The deflection plate with positive and negative voltage passes through the middle, and the charged ink droplets will be deflected when passing through the deflection plate. The degree of deflection depends on the amount of charge. The non-charged ink droplets will not be deflected, and will fly downward and flow into the recovery tube. , and finally returned to the ink tank for recycling through the recycling pipeline. The charged and deflected ink droplets fall at a certain speed and angle onto objects passing in front of the vertical jet. The information to be printed is processed by the computer motherboard, changing the charge of the ink droplets, and different identification information can be generated.

The main purpose of the large character inkjet printer is to facilitate product identification. By marking the product with special logo, brand name and trademark pattern, etc., the product can stand out from the competition and improve the brand awareness. The need for product tracking records. The batch number, shift or production date of the product is directly printed on the product, so that each product has good traceability, which greatly facilitates the quality management of the enterprise and the regional management of the product. Prevent counterfeiting. Manufacturers can often prevent and suppress counterfeiting by labeling products, and the application of new technologies enables legitimate manufacturers to stay ahead of counterfeiters. Increase the added value of the product. Marking the trademark or the name of the manufacturer on the plastic pipe means a commitment, and consumers usually think that this is the product of an enterprise with relatively complete quality tracking and responsible for product quality. Improve production efficiency and reduce production costs. The choice of cij printers in different industries are used in many industries such as food, beverage, building materials, wire and cable, medicine, chemical industry, electronics, etc. Therefore, it is particularly important to choose the most suitable cij printer for product types.
