Description

Technical Field

[0001] This utility model relates to the field of inkjet printer technology, and in particular to an inkjet printer ink filtering mechanism. Background Technology

[0002] A coding machine is a device that uses software control to mark products in a non-contact manner.

[0003] The small nozzle diameter of inkjet printers makes them susceptible to clogging by impurities in the ink, affecting print quality, increasing ink flow resistance, altering viscosity, and causing wear and tear on pumps, valves, and other components, even corroding metal parts. Therefore, ink must be filtered to ensure the normal operation and extended lifespan of the inkjet printer. The internal filter structure of the inkjet printer needs to be maintained or replaced regularly after prolonged use to prevent filter clogging from affecting filtration efficiency. However, traditional inkjet printers have simple internal filter structures, and ink leakage can occur during replacement.

[0004] Based on this, an ink filtering mechanism for inkjet printers is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an ink filtering mechanism for a coding machine in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ink filtering mechanism for an inkjet printer includes a filter cylinder, a filter element connected inside the filter cylinder, a filter screen connected to the filter element, an ink inlet on the filter element, and a sealing joint threaded to one side of the filter cylinder. The sealing joint is provided with a leak-proof component to prevent ink leakage between the connecting structures when the filter element is disassembled.

[0008] Preferably, a second connecting ring is connected inside the filter cylinder, a connecting cover is connected to the second connecting ring, and the filter element is threadedly connected to the connecting cover.

[0009] Preferably, multiple ink inlets are provided, and the multiple ink inlets are evenly arranged around the filter element.

[0010] Preferably, the leak-proof component includes a sealing disc, which is connected to the sealing joint by a spring.

[0011] Preferably, a connecting ring is connected inside the sealing joint, and one end of the spring is connected to the connecting ring.

[0012] Preferably, a rubber ring is connected to the sealing disc.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This application adopts a sealing disc structure, which allows the sealing disc to quickly abut against the sealing joint side when the filter structure is disassembled, thereby sealing the ink outlet and preventing ink leakage.

[0015] 2. This application adopts a filter structure, which enables the inkjet printer to quickly replace the filter structure connecting the ink delivery pipeline. The replacement operation is simple and easy to learn. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] An ink filtering mechanism for an inkjet printer includes a filter cylinder 1, a filter element 8 connected inside the filter cylinder 1, a filter screen 11 connected to the filter element 8, an ink inlet 9 on the filter element 8, and a sealing joint 2 threadedly connected to one side of the filter cylinder 1. The sealing joint 2 is provided with a leak-proof component to prevent ink leakage between the connecting structures when the filter element 8 is disassembled.

[0025] Specifically, such as Figure 2 As shown, a connecting ring 7 is connected inside the filter cylinder 1, and a connecting cover 10 is connected to the connecting ring 7. The filter element 8 is threaded onto the connecting cover 10. During the filtration process, the ink will pass through the center of the connecting cover 10.

[0026] Specifically, such as Figure 3 As shown, multiple ink inlets 9 are provided, and the multiple ink inlets 9 are evenly arranged around the filter element 8. The ink inlets 9 can perform the primary filtration of ink.

[0027] Specifically, such as Figure 4 As shown, the leak-proof assembly includes a sealing disc 5, which is connected to the sealing joint 2 by a spring 4. The spring 4 pushes one side of the sealing disc 5 against the sealing joint 2, thus completing the sealing of one end of the sealing joint 2.

[0028] Specifically, such as Figure 4 As shown, a connecting ring 3 is connected inside the sealing joint 2, and one end of the spring 4 is connected to the connecting ring 3.

[0029] Specifically, such as Figure 4 As shown, a rubber ring 6 is connected to the sealing disc 5. By setting the structure of the rubber ring 6, the spring 4 pushes one side of the sealing disc 5 to abut against the sealing joint 2. The sealing efficiency is improved by relying on the rubber ring 6 set between the abutment structures.

[0030] In summary, the ink filtering mechanism for a coding machine provided in this embodiment allows ink to pass through the center of the connecting ring 3 during ink filtration inside the coding machine, and then enter the filter element 8 through the ink inlet 9 on the outside of the filter element 8. The ink inlet 9 can initially filter the ink, removing large particulate impurities in the ink. Then, the ink completes the final filtration through the filter screen 11. The ink then repeats the above filtration steps in reverse, and finally, it is delivered to the printhead area for coding.

[0031] When the filter structure needs to be replaced, simply rotate the filter cylinder 1 and remove it from the sealing joint 2 connected at both ends. After removal, since the spring 4 will not be pushed by one end of the filter element 8, the sealing plate 5 will be pushed to one side and abut against the sealing joint 2, so that the joint is sealed and ink leakage in the pipeline is prevented. Then, the filter element 8 can be unscrewed to clean the filter screen 11 or replace the filter element 8.

[0032] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
