Application of cement spray code machine

Cement bags traditionally use manual printing, ink roll printing and other methods. They have defects such as unclear numbers, short retention time, and easy erasure during transfer. In recent years, with the development of scientific skills, large-character inkjet printers suitable for cement packaging bags have been presented, and this skill has been widely used in large cement plants. Large-character coding can be actively sprayed on the assembly line of the cement production company. The height of the coding font is around 2 cm, the font is clear and the adhesion is very good. The principle of inkjet printer printing is that the nozzle is composed of 7 solenoid valve nozzles. Through the switch of the host control valve, the dot matrix character information is ejected. The digital information can be time, shift, and number of prints, and it can be active Increment. When the printer is installed, it is necessary to supply a good power supply (220 volts to 5%, 50 Hz) and a reliable ground wire. If external air supply is used, it is necessary to supply clean, dry, oil-free compressed air to the ink system and install a regulating valve. The baffle plan should meet the skill requirements of the printer's homework. Generally, when the vertical distance between the nozzle and the product printing surface is less than 6 mm, the printing effect is best; the maximum vertical distance should be less than 20 mm, otherwise, it is difficult to ensure the clarity of the printed characters , Beautiful, that is, each bag can be coded, and it has a good effect on the use of the two-mouth packaging machine. Regarding the four-nozzle packaging machine, it is advocated that the distance between the four nozzles of the packaging machine should be slightly larger when planning the packaging machine to avoid stacking two bags, or if the two bags are too close to cause the inkjet printer to leak. Regarding the operation of the current four-nozzle packaging machine, it should be operated on a standard basis to avoid the occurrence of the above problems. In short, the use of large-character inkjet printer skills reduces the labor intensity of workers, improves labor productivity, provides a basis for the classification, batch number, and calculation of commodities, and is conducive to quality management. The clear and standard numbers on the cement bag can be retained for a long time. , Provides a basis for discrimination of the anti-counterfeiting and anti-counterfeiting of the cement quality of the factory.
