The oil drum has the advantages of reasonable structure, precise production, beautiful appearance and convenient operation. It has the advantages of sturdiness and durability, low wear, high mechanical strength, not easy to break, and tight lid. It should be widely used in lid making, barrel making, can making, lubricants , Coating, chemical, petroleum, grain and oil and other liquid packaging industries, which are convenient for storage and transportation. Generally, it is necessary to mark company information and product specifications, models, serial numbers and other content on the surface of oil drums. Traditional companies generally use templates to manually spray paint for marking, which increases time and labor costs. The printed content is easy to store or store for a long time. Displacement and blur are prone to occur during transportation. EBS handheld inkjet printer is the world's first portable inkjet printer. It adopts ergonomic design, small and exquisite appearance and strong endurance. It is widely used in large and irregular objects, or outdoor operations. Under the influence of the production or storage environment, oil stains or other liquids will adhere to the surface of the oil drum, which will affect the integrity of the printed content and easily cause wear or corrosion to the nozzle. Therefore, the requirements for the printer equipment are relatively strict. EBS handheld inkjet printer is different from the piezoelectric or thermal bubble nozzles of other automatic inkjet printers on the market. It adopts an innovative solenoid valve nozzle design and artificial ruby u200bu200bnozzles. It has wear resistance, high temperature resistance, corrosion resistance, and The advantages of plugging the nozzle extend the service life of the handheld inkjet printer. A variety of inks can be selected according to the needs, which will dry within a few seconds after printing and adhere well to the surface. During the storage or transportation of the oil drum, it will not be transferred to other locations and will not affect the subsequent processes. The surface is clean, tidy and beautiful. The EBS smart inkjet printer has a very wide range of applications. It can print complete content on the surface of different specifications, models or materials to meet the marking requirements of permeable and non-permeable materials.
