Constant-pressure buffer distributor of printer ink pipeline

Abstract

The invention relates to the field of printer assemblies, in particular to a constant-pressure buffer distributor of a printer ink pipeline. The constant-pressure buffer distributor of the printer ink pipeline comprises an ink inlet, an ink outlet and a buffer groove. The ink inlet and the ink outlet are respectively communicated with the buffer groove. A sealing film and a buffer film subjected to deformation processing are arranged on the buffer groove and form an air sealing cavity with an air inflation port and an air outlet in a sealing mode, the buffer film is sealed above the buffer groove, and the air inflation port is connected with an air inflation pump. The air outlet is provided with a pressure sensor and an air release valve. The constant-pressure buffer distributor of the printer ink pipeline can produce constant pressure under the action of the air inflation pump, feeds ink with the constant pressure into a printing head through buffering effect of the ink buffer groove, can well overcome ink gravity and resistance in the pipeline and can ensure a printer to work normally, continuously and uninterruptedly.

AI Technical Summary

Problems solved by technology

At present, the ink supply pipeline commonly used by printers is a straight-through pipeline from the ink cartridge to the end of the print head or a simple one-point-two pipeline with a three-way joint in the middle, and the ink output of the print head is based on the needs of the printed picture. Fast and dynamic changes, and the rapid change of the terminal demand is very slow after the damping attenuation of the long pipeline, and the ink cartridge at the initial end of the pipeline is very slow, causing the ink supply to be untimely and the ink to be printed out

However, if a simple method of adding a three-way connection and one split into two will increase the risk of instantaneous change in the flow rate before and after the joint in the pipeline system, and even cause backflow due to the different ink requirements of the two separate pipelines, thus causing The print head cannot get a continuous and stable supply of ink

[0003] Especially now that large-format inkjet printers are widely used in the field of professional graphics, but many domestic printers are relatively poor in speed and quality of printed images. The main reason is that the number of print heads on a printer is relatively small

Generally, there are only 2 or 4 heads, and when multiple print heads are used, the corresponding ink pipelines are not properly arranged and designed, which cannot ensure a stable and continuous supply of ink to the print head, and the print head is easy to break the ink, so the quality of the printed picture poor

[0004] At present, many manufacturers of large-format inkjet printers on the market only use ordinary one-to-two connectors to deal with multiple print heads, that is, figure 1 , 2 For the three-way joint shown, this three-way joint is provided with three interfaces, which are ink inlet 1a, ink first outlet 1b, and ink second outlet 1c. The hole areas of these three interfaces are all the same size. In this way, the flow of ink does not fully meet the ink volume required by the print head, and the output ink does not have a constant pressure, which directly affects the quality of the printed image

In addition, the printer needs to clean the print head at a higher frequency to basically meet the printing needs, which seriously affects the work efficiency and printing continuity, and creates a lot of trouble for users.

In addition, high-frequency cleaning of the print head will directly affect the life of the print head, which will cause great losses to customers
