In order to better understand the handheld inkjet printer we use, we need to understand its composition structure and operating principle.
Whether it's a factory assembly line or doing product labeling in small batches, we all need to know what the various components of the handheld inkjet printer do and what their functions are. So today I will explain the structure of the handheld inkjet printer to a wide range of users. Composition and operating principle.
Composition and structure diagram of handheld inkjet printer
Different brands and different types of handheld inkjet printers have different structural characteristics, but the general structure is similar, as shown in the following figure:
1. Operate the contact display screen to modify the information content to be printed (you can modify Chinese and English, symbols, QR codes, barcodes, pictures, etc.), and the font can be set to dot matrix, hollow, and normal.
2. Turn on the machine switch button, turn on the machine or turn off the machine
3. Handle, with batteries inside, easy to carry, do not need to connect to the power cord to use, can last for more than 8 hours on a single charge.
4. The nozzle slot, as the name suggests, is the nozzle of the inkjet printer, and is also the place where the inkjet printer prints and ink jets.
5. Synchronize the wheel to synchronize the specific position where we want to code
6. RS232 serial port or optical interface, used to connect external data applications
7. USB interface, used to map or other content to be coded
8. Drive belt, which can be used with an inkjet printer for automated spray printing on the assembly line
9. Ink cartridge area, an area specially designed for inserting ink cartridges. The ink cartridges are equipped with chips, which must be inserted correctly before they can be used. The nozzle height of an HP ink cartridge is 12.7mm high as standard.
Working principle of handheld inkjet printer
A handheld inkjet printer, also known as a portable inkjet printer, is a kind of inkjet printing equipment that can be carried with you. It is usually used to print trademark pictures, Chinese and English logos, numbers, barcodes, QR codes, etc. Its characteristics are light and compact, clear spray printing, and high degree of functionality and informatization.
The operating principle of the handheld inkjet printer is similar to high-resolution. The central parts include the nozzle, synchronizer, software operating system and handheld architecture. The effect of coding is related to the type of nozzle and the maintenance status of the nozzle. Under normal conditions, it can reach a resolution of up to 300 DPI, which is the same as spraying and photo painting. The printed effect can be achieved, which is very clear and looks very beautiful.
The principle of the handheld inkjet printer mainly lies in the nozzle. Take the nozzle using hot bubble inkjet technology as an example. The nozzle uses semiconductor thin film technology, and uses laser process and high-precision coating technology to form multiple nozzles with a diameter of about 50 microns. hole. These nozzles are placed at a high density. After receiving the heating signal, current is used to heat the ink to about 260 ° C in an extremely short moment. Part of the ink is heated to form bubbles that expand and eject the ink, forming various characters, pictures LOGO and other characters.
Usage scenarios of handheld inkjet printers
Because of its portable, large-capacity rechargeable lithium batteries, and the ability to customize character heights and sizes according to customer requirements, the handheld inkjet printer is widely used in the outer packaging of food, beverages, wine, etc., as well as various steel pipes, woven bags, gypsum board, etc. It can be used in the workshop, or in warehouses, logistics freight yards, offices, etc. It can print production date, operation serial number, production shift number, anti-counterfeiting and anti-smuggling codes (or invisible characters), company name, Graphical icons, etc.
As the saying goes, the plan for a year lies in spring. Just after the New Year is the time when many industries are ready to start construction, and this time is the peak season for inkjet printer stores. For example, if some orders are backlog during the Spring Festival and require rapid processing, then inkjet printers are needed at this time. During this period, both orders for new machines and purchases of ink cartridges are relatively large.
When purchasing an inkjet printer, you must choose a regular brand, and the quality will be more guaranteed.
The quality of different brands of identification equipment varies greatly. When purchasing a printer, the price factor comes first, but don't forget the importance of quality. An inkjet printer with good quality, reliable brand, and stable application function can be used for a long time
