DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme of the utility model clear, complete and the advantages more clear and clear, the embodiments of the utility model are further described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the utility model, not all embodiments, and are used to explain the embodiments of the utility model, and do not limit the embodiments of the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of protection of the utility model.

[0018] Please refer to Figs. 1 to 4The utility model provides a technical scheme: a kind of plastic soft package printing ink tank's closed shielding mechanism, comprising: closed ring 4 and threaded rod 10, the inner wall of closed ring 4 contacts box cover 2 with box 1, box 1 is cylindrical, it is convenient to store ink, the upper end of box cover 2 is fixedly connected with motor 5 and aerator 6, by motor 5 and aerator 6 can be convenient to keep the normal state of ink, avoid too much adhesion, the lower end of box cover 2 is fixedly connected with rubber ring 3, rubber ring 3 is located in box 1, and the outer surface of rubber ring 3 is in contact with the inner wall of box 1, by rubber ring 3 can effectively improve the closed nature of the connection between box 1 and box cover 2, avoid the joint of box 1 and box cover 2 Gap appears, the lower end of box 1 is fixedly connected with ink outlet pipe 12, box 1 is connected with printing device by ink outlet pipe 12, and the ink in the inside flows into printing device by ink outlet pipe 12.

[0019] Closed ring 4 is U-shaped as a whole, the inner wall of which closely fits the joint of box cover 2 and box 1, and the sealing performance between box 1 and box cover 2 can be further enhanced by closed ring 4. One end of the closed ring 4 is rotatably connected to a rotating block 7, and the other end of the rotating block 7 is connected to a sliding block 8. The sliding of the sliding block 8 can cause the two ends of the closed ring 4 to move closer to or further away from each other, thereby changing the degree of fit of the closed ring 4 with the box 1 and the box cover 2. The output end of the motor 5 passes through the box cover 2 and is fixedly connected to a rotating column 15. The rotating column 15 is driven to rotate by the motor 5. The lower surface of the rotating column 15 is fixedly connected to three fan blades 13. When the rotating column 15 drives the fan blades 13 to start rotating, the fan blades 13 will start to stir the ink in the box 1, thereby improving the fluidity and adhesion of the ink. The surface of the fan blades 13 is provided with a plurality of through holes 14. The through holes 14 can further improve the efficiency and effectiveness of stirring.

[0020] The inner wall of the rotating block 7 is provided with a sliding groove 9, and the sliding block 8 is slidably connected to the sliding groove 9. The sliding groove 9 can limit and guide the sliding block 8. The surface of the sliding block 8 is provided with a threaded hole. The two ends of the closed ring 4 are provided with circular holes. The threaded rod 10 can be guided by the threaded hole. One end of the threaded rod 10 is fixedly connected to a limiting column 11. The limiting column 11 is convenient to operate and can fix the position of one end of the closed ring 4. The other end of the threaded rod 10 passes through the two ends of the closed ring 4 and the sliding block 8 in sequence. The threaded rod 10 is threadedly connected to the threaded hole, and the threaded rod 10 is in contact with the inner wall of the circular hole. When the threaded rod 10 rotates, the sliding block 8 will slide along the sliding groove 9. At this time, the sliding block 8 will continuously press one end of the closed ring 4, causing it to continuously approach the other end of the closed ring 4. The output end of the aerator 6 is fixedly connected to an air bag 16, which is rotatably connected to the surface of the rotating column 15. The air bag 16 is in a folded and contracted state. During operation, the air bag 16 is inflated to expand, thereby ensuring the liquid pressure of the ink outlet pipe 12 and the stability of the pressure inside the box 1.

[0021] When the device works, after the checking device is correct, the ink is loaded into the box body 1, then the sealing ring 4 is installed, after the installation is completed, the threaded rod 10 is inserted, and the threaded rod 10 is rotated through the limiting column 11, so that the sliding block 8 slides, the two ends of the sealing ring 4 gradually approach, the sealing ring 4 gradually shrinks as a whole to complete the sealing of the whole, the motor 5 and the inflator 6 are started, so that the ink in the box body 1 always keeps fluidity, and when the ink is reduced, through the inflation of the air bag 16, the pressure in the box body 1 and the output pressure of the ink outlet pipe 12 can be kept stable, the whole device is simple and convenient to operate and has high sealing performance.

[0022] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
