Description

Technical Field

[0001] The utility model relates to an adjustable nozzle holder, specifically a positioning mechanism for a nozzle of an inkjet printer, belonging to the technical field of nozzle holders. Background Technique

[0002] An inkjet printer is a device that uses software control to perform non-contact marking on products. Generally refers to continuous inkjet technology, abbreviated as CIJ. With the development of China's electronic industry, more and more inkjet printer manufacturing factories have been established in China. The main production areas of Chinese inkjet printers are in Shanghai, Zhuhai, Beijing, Shandong, Jiangsu, Shenzhen, and Guangzhou. Inkjet printer brands can be divided into imported brands, joint venture brands, domestic brands, and foreign-funded brands. There are more than a hundred specific brand names. Inkjet printers are also divided into small character inkjet printers, large character inkjet printers, high-resolution inkjet printers, laser inkjet printers, UV inkjet printers, etc.

[0003] An inkjet printer uses the principle of deflecting charged ink particles by a high-voltage electric field to spray patterns, characters, and numbers on the surfaces of various objects. It is a high-tech product integrating mechatronics. The products are widely used in the food industry, cosmetics industry, pharmaceutical industry, parts processing industries such as automobiles, wire and cable industries, aluminum-plastic pipe industries, tobacco and alcohol industries, and other fields. It can be used to spray production dates, batch numbers, barcodes, trademark patterns, anti-counterfeiting marks, and Chinese characters. It is a powerful device for implementing the health law and promoting packaging modernization.

The nozzle head is installed on the adjustment bracket through the positioning component, and the adjustment bracket is used to adjust the position of the nozzle head; the positioning component includes a vertical plate and a clamping plate fixed on the vertical plate. The clamping plate is provided with an insertion hole for the nozzle head to be inserted. One side of the clamping plate is provided with an installation notch communicating with the insertion hole. The clamping plates on both sides of the installation notch are made of elastic materials. A positioning ring is fixed on the outer circumference of the nozzle head. When the nozzle head is inserted into the insertion hole through the installation notch, the positioning ring abuts against the top wall of the clamping plate.

[0005] The device also uses the installation notch to clamp the nozzle, and then uses a positioning strip to fix it. Although the nozzle can be quickly disassembled and assembled, and the nozzle positioning efficiency can be improved, the fixing method of this structure causes the nozzle to be fixed unstably, and it is very easy to cause problems such as the nozzle installation being loose or shaking. Therefore, the positioning of the nozzle by the positioning mechanism for the nozzle of the inkjet printer is unstable, affecting the use effect of the nozzle of the inkjet printer.
