The UV ink filtering device is not easy to block, convenient and quick to clean and good in filtering performance.

The filter cartridge 100 serves as a main body part of the UV ink filtering apparatus, and the main filtering operation of the ink is performed in the filter cartridge 100. In this embodiment, the filter cartridge 100 is a cylindrical structure, the connecting port 110 is located at one side of the filter cartridge 100, and the connecting port 120 is located at the other side of the filter cartridge 100, so as to facilitate the filtering operation.

The carrier plate 200 is used to seat the heating tube 600 so that the user can take out the heating tube 600 through the carrier plate 200. The supporting plate 200 is covered on the abutting port 110 and abuts against the filter cartridge 100 through the abutting block 111. In this embodiment, the supporting board 200 is a circular plate structure, the abutting port 110 is a circular opening, and the abutting block 111 is a circular ring structure. Thus, the supporting plate 200 is easily abutted against the filter cartridge 100 at the abutting opening 110, and the supporting plate 200 is prevented from falling into the filter cartridge 100 from the abutting opening 110. The user is through carrying and taking loading board 200, alright take out heating pipe 600 in the lump to be convenient for the user to clear up or maintain the change work to heating pipe 600, promoted this UV printing ink filter equipment's maintainability.

The receiving cap 300 serves to receive fine foreign substances settled on the bottom of the filter cartridge 100. The receiving cap 300 is screwed to the bottom of the filter cartridge 100, and the ink settles in the filter cartridge 100 and fine impurities in the ink settle on the receiving cap 300. The surface ink in the filter cartridge 100 will enter the outlet conduit 500 to provide filtered ink. The receiving cap 300 is screw-coupled to the filter cartridge 100 in such a manner that the receiving cap 300 can be removed from the filter cartridge 100, thereby facilitating a cleaning work by a user. In this embodiment, the receiving cover 300 is a U-shaped structure, a thread groove is formed on the inner side wall of the receiving cover 300, and a thread ridge is formed on the outer side wall of the bottom of the filter cartridge 100, and the thread groove is matched with the thread ridge. Thus, the receiving cap 300 can be removed from the filter cartridge 100 by twisting, so that the user's cleaning work can be conveniently performed.

In order to facilitate the placement of the receiving cap 300 when the receiving cap 300 is removed, in one embodiment, the UV ink filtering apparatus further includes a connection cord 700, one end of the connection cord 700 is connected to the receiving cap 300, and the other end of the connection cord 700 is connected to the filter cartridge 100. Thus, when the receiving cap 300 is removed, it is suspended near the filter cartridge 100 by the connection cord 700 without additional positioning of the receiving cap 300.

To facilitate the delivery of ink, in one embodiment, the delivery tube 500 is at a second predetermined angle from horizontal, and the input end of the delivery tube 500 is positioned vertically above the output end of the delivery tube 500. In this embodiment, the second predetermined included angle is 30 degrees. Thus, when the surface ink is over the input end of the output tube 500, the ink can flow from the input end to the output end of the output tube 500 under the action of self gravity, thereby improving the convenience of ink output. In order to further improve the filtering performance of the UV ink filtering device, in one embodiment, a post-filter 510 is disposed in the output pipe 500. In this embodiment, the post filter 510 is a magnet filter to further remove iron powder impurities dissociated in the ink. In another embodiment, the post-filter 510 is a fibrous filter to further remove fine impurities free in the ink. Thus, the filtering performance of the UV ink filtering device is further improved.

To enhance the structural strength of the UV ink filter assembly, in one embodiment, the inlet conduit 400, filter cartridge 100, and outlet conduit 500 are integrally formed. Thus, the input tube 400, the filter cartridge 100 and the output tube 500 are firmly connected and are not easily separated and fall off. Thus, the connection stability of the input pipe 400, the filter cartridge 100 and the output pipe 500 is improved, and the working stability of the UV ink filtering device is improved.

The heating pipe 600 is used for heating the ink in the filter cartridge 100 to improve the fluidity thereof, and the ink which is prevented from being agglomerated and solidified is isolated and filtered, thereby improving the effective filtering degree of the ink. To promote uniform heating of the ink, in one embodiment, the heating tube 600 is in a spiral configuration. Thus, the heating tube 600 can heat the ink sufficiently to ensure good fluidity of the ink. Thus, the effectiveness of filtering the ink is improved. Further, to avoid ink from adhering to the inner wall of the filter cartridge 100, in one embodiment, the heating tube 600 is disposed adjacent to the inner wall of the filter cartridge 100. Thus, the heating pipe 600 is facilitated to heat a portion of the ink adhered to the inner wall of the filter cartridge 100. Thus, the filtering effectiveness of the ink is improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
