Inkjet printers are mainly used in the pharmaceutical industry, food industry, etc.

The inkjet printer is mainly used in the pharmaceutical industry, food industry, beverage industry, cosmetics industry, stationery industry, automobile manufacturing industry, industrial pipes, chemical industry, electronics, electrical industry and other occasions. It has a real clock and can print information that changes with time. Such as date, shift, text, batch number, but also print characters, product names and logos. Because it adopts non-contact coding technology, it can print almost any shape on objects, and can print on a variety of materials without being limited by size and texture, including glass, plastic, rubber, PVC cable and Pipes, various metals, magnetic materials, etc. The inkjet printer adopts multi-language programming, multiple operating languages u200bu200bcan be selected, and the all-Chinese operating interface is used, which is more convenient to use. It can print in multiple directions, including side-jet and top-jet, and it can print at the same time. Edit new information to improve productivity; with pattern and date editing functions, you can edit patterns and date formats at will, with powerful functions. The problems of the inkjet printer applied to magnetic materials for marking (1) The inkjet printer has no automatic feeding device and needs to manually discharge the workpiece, which is slow and low efficiency; (2) The workpiece is sent by the conveyor belt after coding In the loading box, the polarity marking direction of the workpiece is reversed out of order at this time, and then the marked products need to be manually arranged according to the polarity requirements. The work efficiency is low, and manual operation is easy to make the polarity direction wrong. Based on the above problems, we modified the electromagnetic vibrating feeder for automatic feeding, and magnetized the workpiece marked by the inkjet printer to make the workpiece polarized. The arrangement of sex marks is consistent, which is convenient for subsequent procedures and improves work efficiency. Transformation of the electromagnetic vibrating feeder The working principle of the electromagnetic vibrating feeder: under the action of the electromagnetic vibrator, the hopper vibrates up and down torsionally, so that the workpiece moves along the spiral path from low to high, and is automatically arranged and oriented until the upper part The discharge port enters the feeding trough, and then is sent to the corresponding station by the feeding mechanism. However, because the workpiece to be processed is marked on the cylindrical surface (take the Φ5×5.4mm cylindrical product as an example), when the workpiece is moved from the feeding trough to the conveyor belt, the workpiece will be shaken due to the conducted vibration. In this regard, we use the feed trough segmentation to solve this problem, and fix one section of the feed trough on the conveyor, parallel to the conveyor belt. The notch of the other section of the feeding trough faces the notch of the previous section and is separated by a space of about 1mm to isolate the vibration transmitted by the electromagnetic vibration feeder, thereby effectively solving the problem of the workpiece being shaken.
