[0022] To make the technical solution of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0023] Embodiment 1

[0024] Combined with the attached Figures 1-5 , an ink refilling structure for a non-exposed seal of a re-inking seal, the ink refilling structure of this technical solution is mainly adapted to a stamping machine. By directly setting this structure on the stamping machine, the effect of refilling the seal without taking out the seal on the stamping machine can be realized.

[0025] The stamping machine adopting this technical solution is provided with a housing. Inside the housing, a fixing plate 11 is arranged on the side. Inside the housing, a fixture assembly 10 is provided. A seal is arranged inside the fixture assembly 10. When the fixture assembly 10 descends, the fixture assembly extends out of the housing of the stamping machine, so as to perform the stamping work. Below the fixture assembly 10, there is a door 12 which is rotatably arranged on the fixing plate 11. The door 12 cooperates with the fixture assembly 10, so that the fixture assembly 10 can push the door 12 to rotate and open. At this time, the fixture assembly 10 extends out of the housing of the stamping machine. When the fixture assembly 10 does not descend, the door 12 covers the bottom of the fixture assembly 10. The door 12 is used to protect the seal inside the fixture assembly 10, preventing the seal from being damaged or misappropriated.

[0026] An ink filling structure is arranged on the door 12. Inside the door 12, there is an ink cartridge bracket 13. A rotating ink cartridge 14 is clamped inside the ink cartridge bracket 13. A blotting sponge 15 is arranged inside the rotating ink cartridge 14. The ink cartridge bracket 13 is used to install the rotating ink cartridge 14 on the door 12. The ink cartridge bracket 13 and the door 12 are in a detachable matching structure for replacing the blotting sponge 15. When the blotting sponge 15 needs to be replaced, the ink cartridge bracket 13 can directly carry the rotating ink cartridge 14 and the blotting sponge 15 and take them out of the door 12, so that the user can replace the blotting sponge according to needs.

[0027] The rotating ink cartridge 14 is clamped on the ink cartridge bracket 13. The rotating ink cartridge 14 has rotational kinetic energy. The rotating ink cartridge 14 does not rotate circumferentially, but rotates in an up-and-down swing with the clamping position of the rotating ink cartridge 14 on the ink cartridge bracket 13 as the center point. Through the rotation of the rotating ink cartridge 14, the blotting sponge 15 inside the rotating ink cartridge 14 can make more sufficient contact with the seal inside the fixture assembly 10.

[0028] On one side of the rotating ink cartridge 14 close to the fixing plate 11, there is a protruding mating ear 16. On the same side of the fixture assembly 10 located on the fixing plate 11, there is a push plate that mates with the mating ear 16. When the fixture assembly 10 rises and falls, the push plate of the fixture assembly 10 abuts and mates with the mating ear 16 of the rotating ink cartridge 14, so as to make the rotating ink cartridge 14 rotate. At this time, the rotation of the rotating ink cartridge 14 drives the internal blotting sponge 15 to rotate, so as to make more sufficient contact with the seal inside the fixture assembly 10, making the pattern clearer when stamping.

[0029] An injection hole 17 penetrating the bottom of the rotating ink cartridge 14 is arranged inside the rotating ink cartridge 14. The rotating ink cartridge 14 has a regular shape. The rotating ink cartridge 14 is preferably circular. The injection hole 17 is located at the center of the rotating ink cartridge 14. The injection hole 17 is used for an ink injection device to inject ink into the injection hole 17, and the replenished ink is directly injected into the rotating ink cartridge 14 through the injection hole 17.

[0030] An injection hole 17 is provided on the inner bottom surface of the rotating ink cartridge 14, and a temporary ink storage groove 18 is provided outside the injection hole 17. The temporary ink storage groove 18 is an annular groove and is communicated with the injection hole 17. The injection hole 17 is located at the center of the temporary ink storage groove 18. A plurality of ink flow channels 19 are also provided on the inner bottom surface of the rotating ink cartridge 14. The ink flow channels 19 are arranged to diverge outward with the temporary ink storage groove 18 as the center point. The ink flow channels 19 are arranged in a star-shaped divergence. One end of the plurality of ink flow channels 19 is communicated with the temporary ink storage groove 18 located at the center of the rotating ink cartridge 14, and the other end of the plurality of ink flow channels 19 is arranged toward the outer wall of the rotating ink cartridge 14 at the other end of the rotating ink cartridge 14. The ink cartridge is provided with more flow channels. When injecting ink from the bottom, the ink can be spread evenly faster through the flow channels, reducing the waiting time.

[0031] A protruding receiving groove 20 is provided on the outer side of the bottom of the rotating ink cartridge 14. The center position of the receiving groove 20 corresponds to the center position of the injection hole 17. Butyl rubber 21 is installed in the receiving groove. The center position of the butyl rubber 21 corresponds to the injection hole 17. The ink injection device can be inserted into the injection hole 17 with the butyl rubber 21 to inject ink into the rotating ink cartridge 14. After the ink injection device is pulled out and retracted, due to the characteristics of the butyl rubber 21 itself, the butyl rubber 21 will block the injection hole 17, so that the ink in the rotating ink cartridge 14 cannot leak out from the injection hole 17.

[0032] An injection opening 22 is provided through the storage door 12. Generally, the ink cartridge holder 13 does not have a structure covering the bottom surface of the storage door 12. Therefore, only an opening needs to be provided on the storage door 12. The injection opening 22 on the storage door 12 corresponds to the injection hole 17 and the receiving groove 20. When the user replenishes the ink, there is no need to open the storage door 12 again, and the ink dipping sponge 15 in the rotating ink cartridge 14 can be replenished. The ink injection device is directly inserted into the injection hole 17 through the injection opening 22. At this time, the ink replenishment starts. The ink first converges in the temporary ink storage groove 18, and then the ink in the temporary ink storage groove 18 flows to various positions in the rotating ink cartridge 14 through the ink flow channels 19. At this time, the ink dipping sponge 15 can absorb the ink in the ink flow channels 19 everywhere, completing the replenishment of the ink dipping sponge 15.

[0033] The above-described embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
