Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a stable ink supply structure of an inkjet printer. Background Art

[0002] With the development and progress of inkjet printing technology, the diversification of market demand, and the increasingly wide application fields, the requirements for printing technology are getting higher and higher. For example, in the fields of high-precision and large-volume inkjet printing, circuit board solder mask and character printing, special inks need to be printed on the medium. At the same time, the printing needs to meet the requirements of high precision, while taking into account economic benefits, and the efficiency of printing must be improved. However, in addition to adjusting the width of the printhead and the precision requirements of the nozzle hole, the ink supply of the ink path is extremely important for high-precision, high-efficiency and large-volume inkjet printing technology. A stable ink supply system can ensure the accuracy of printing and the yield of the product. The traditional ink supply method of the printhead in and out can easily lead to insufficient ink supply, poor ink fluidity, and low printing yield. Utility Model Content

[0003] In order to make up for the deficiencies in the prior art, the utility model provides a stable ink supply structure for an inkjet printer, which can effectively enhance the ink activity at the ink supply end of the print head, further improve the fluidity of the ink, and meet the requirements of high-precision printing.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A stable ink supply structure for an inkjet printer comprises a main ink inlet tube, one end of which is provided with two ink outlets, the ink outlets are connected to auxiliary ink inlet tubes, heating wires are wound around the main ink inlet tube and the auxiliary ink inlet tubes, and a temperature probe is provided inside the main ink inlet tube.

[0006] Furthermore, a heat insulating sleeve wrapping the heating wire is provided outside the main ink inlet pipe and the auxiliary ink inlet pipe.

[0007] Furthermore, the auxiliary ink inlet tube is connected to the ink outlet via an ink tube joint, and the ink tube joint is threadedly connected to the ink outlet.

[0008] Furthermore, the auxiliary ink inlet pipe is a hose or a copper pipe.

[0009] Furthermore, the auxiliary ink inlet pipe is connected to two interfaces of the print head.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The utility model changes the traditional ink inlet and outlet ink supply mode of the printing head into a double ink inlet mode by connecting the ink outlet end of the main ink inlet tube in two parts and connecting the auxiliary ink inlet tube in two parts. Under the condition of the same pressure and the same diameter of the ink inlet tube, the ink inlet flow rate can be doubled to ensure uninterrupted and sufficient ink supply. At the same time, the main ink inlet tube and the auxiliary ink inlet tube are wrapped with heating wires on the outside. The temperature of the heating wires can be accurately controlled by the temperature detection head, which can effectively enhance the ink activity at the ink supply end of the printing head, further improve the fluidity of the ink, meet the requirements of high-precision printing, effectively stabilize the ink supply, and ensure the printing quality.
