Ink circulation stirring device of large-character inkjet printer

Abstract

The invention discloses an ink circulation stirring device of a large character inkjet printer. The ink circulation stirring device of the large-character inkjet printer comprises an air inlet, a manual ball valve, a left pressure adjusting device, a right pressure adjusting device, a safety valve, a liquid level observable sealed ink box, a print head, a pneumatic double-diaphragm pump, a filter energy storage tank, a two-position three-way valve, ink bottles and a throttle valve. The ink circulation stirring device of the large-character inkjet printer is simple to operate and stable in performance, can improve jet printing quality, lowers the blocking rate, the using cost, the maintenance cost and the maintenance workloads of the inkjet printer, overcomes the defect that a traditional inkjet printer stirring device has to stop working when ink is added, and improves the competitiveness of products.

Description

technical field [0001] The invention relates to a large-character inkjet printer, in particular to an ink circulation stirring device for the large-character inkjet printer. Background technique [0002] The application of today's logistics identification technology is gradually deepening in every corner, especially in industrial products, the application range is more and more extensive, and the complexity of the application is greatly increased, making identification an indispensable and important part of production quality management in various industries . [0003] The main functions of logistics labeling on products are as follows: [0004] First, it is conducive to product identification. In addition to the brand, trademark, name, model and pattern of the product. By marking special marks on the product, such as: product grade, quality inspector number, etc., the product can stand out from the competition and increase brand awareness. [0005] Second, the need for ...

Problems solved by technology

[0012] In the prior art, the disadvantage of the first solution is that the ink stirring device of the inkjet printer cannot realize the circulation and stirring of the entire pipeline, and the ink flowing to the nozzle will precipitate over time, which will cause the nozzle of the inkjet printer to be blocked. During maintenance, The inkjet printer must stop working before the pipeline and nozzle can be cleaned, which will affect the production progress and cause waste

When the inkjet printer ink stirring device needs to add new ink, the inkjet printer must stop working, and then open the ink tank of the inkjet printer stirring device to unload the pressure and reduce the production efficiency

Disadvantages of the second solution: inkjet printer inks are mostly ketone-based or alcohol-based inks, and most of the cleaning fluids used contain ketones, alcohol and other components. These chemical reagents are flammable and explosive, and electric The diaphragm pump provides pressure for the stirring device. The electric diaphragm pump has a short service life and complex control parts. The risk of mixing hydraulic and electricity is high, and there are hidden dangers in safety.
