Description

Technical Field

[0001] This utility model relates to the field of inkjet printer technology, specifically to a tubular filter for an inkjet printer. Background Technology

[0002] A coding machine is a widely used marking device in industrial production processes. It is mainly used to print text, patterns, QR codes, and other information on the surface of various materials. It achieves marking and identification of object surfaces by heating and evaporating ink or thermal sublimation material and then spraying it out.

[0003] Inkjet printers require filters to filter the inkjet printing liquid. Existing tubular filters typically filter ink through internal filter plates. However, these plates become clogged over time, necessitating complete filter replacement. This prevents internal cleaning and maintenance, affecting ink filtration efficiency and increasing operating costs. Furthermore, tubular filters have poor protection; impacts to the outer shell can deform the internal filter structure, further impacting ink filtration.

[0004] Therefore, it is necessary to provide a new tubular filter for inkjet printers to solve the above-mentioned technical problems. Utility Model Content

A baffle 6 is fixedly connected to one side of the protective rail 5, and a clamping plate 7 is fixedly connected to one side of the baffle 6. The clamping plate 7 limits the movement of the two sets of baffles 6. A housing 8 is installed on the inner wall of the mounting seat 4, and the mounting seat 4 is bolted to the top of the housing 8. For easy disassembly of the housing 8, a box 9 is installed at the bottom of the housing 8. A discharge pipe 10 is installed inside the box 9. A first filter plate 11 is slidably connected to the inner wall of the box 9. The liquid discharged from the discharge pipe 10 can be filtered through the first filter plate 11. A filter cylinder 12 is installed inside the housing 8. Two sets of second filter plates 13 are installed on the inner wall of the filter cylinder 12. The second filter plates 13 achieve the effect of filtering ink liquid. An inlet pipe 14 is installed on the inner wall of the filter cylinder 12. One end of the inlet pipe 14 is connected to the inner wall of the housing 8, so that ink liquid can be injected into the filter cylinder 12.

[0024] A limiting frame 15 is fixedly connected to the top of the base 1. A limiting bolt 16 is threadedly connected to the inner wall of the limiting frame 15. The limiting bolt 16 is used to limit the installation of the limiting frame 15 and the guardrail 5. The guardrail 5 further protects the shell 8. A collection box 17 is provided on the top of the base 1. The filtered ink can be collected through the collection box 17. A collection pipe 18 is provided on one side of the collection box 17.

[0025] A handle 19 is installed on one side of the housing 8. A connecting rod 20 is rotatably connected to the inner wall of the housing 8. A support plate 21 is fixedly connected to one end of the connecting rod 20. One side of the support plate 21 is engaged with one side of the filter cylinder 12 by a locking block.

Ink liquid is injected into the filter cartridge 12 through the inlet pipe 14. The guide seat 23 has an inclined angle on its inner wall, allowing the ink liquid to enter the second filter plate 13 for filtration. After ink filtration, a slight rotation of the connecting rod 20 causes the filter cartridge 12 to swing slightly, raising the filter cartridge 12. The internal ink filtration effect is achieved by rotating the connecting rod 20 to drive the support plate 21 and the filter cylinder 12 to rotate, causing the connecting block 24 to be locked outside the limiting block 25, so that the liquid outlet 22 is connected to the discharge pipe 10, and the filtered liquid is discharged through the discharge pipe 10. The first filter plate 11 can filter the liquid discharged from the discharge pipe 10, improving the filtration effect of the ink liquid. The filtered ink can be collected through the collection box 17 to avoid the problem of ink dripping affecting subsequent use. One side of the support plate 21 is locked to one side of the filter cylinder 12 by a locking block. The filter cylinder 12 can be removed from the mounting plate 27 side for disassembly and cleaning.
