Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 - Figure 4 The utility model provides a technical solution: an automatic ink-adding mechanism for continuous printing, comprising an ink cartridge 1, a feeding chamber 2 and a box cover 4. The feeding chamber 2 is arranged on the upper part of the ink cartridge 1, and the safe ink volume chamber 3 can be added through the feeding chamber 2. The safe ink volume chamber 3 is arranged at the bottom of the feeding chamber 2, and a safe ink volume chamber 3 can ensure that a safe amount of ink is left in the ink cartridge 1. The feeding chamber 2 is communicated with the safe ink volume chamber 3, and the box cover 4 is covered on the top of the ink cartridge 1. The box cover 4 plays a protective role and has a certain dust-proof effect. A sealing ring 41 is arranged between the box cover 4 and the ink cartridge 1, and the sealing ring 41 plays a certain sealing role. A feeding port 5 is arranged on one side of the box cover 4, and the ink cartridge 1 can be supplemented with ink through the feeding port 5.

[0021] The side of the feed port 5 away from the ink cartridge 1 is connected with an ink replenishing tube 6, which plays a connecting role. The end of the ink replenishing tube 6 away from the feed port 5 is connected with an ink storage barrel 7, in which a large amount of ink is stored for replenishment of the ink cartridge 1. An ink pump 8 is arranged in the middle of the ink replenishing tube 6, and the ink pump 8 can extract the ink in the ink storage barrel 7 to the ink cartridge 1 through the ink replenishing tube 6 for replenishment. A connecting rod 9 is connected to the center of the bottom of the box cover 4, and the connecting rod 9 plays a connecting role. The end of the connecting rod 9 away from the box cover 4 is connected to a guide plate 10, which plays a guiding role. The flow effect prevents the ink from directly impacting the float 3 and causing multiple shocks. The bottom edge of the guide plate 10 is connected with an annular filter 11. The annular filter 11 plays a filtering role, filtering and removing tiny particles and impurities in the ink, which can avoid color difference, spots, blurring and other problems in printed products. The edge of the annular filter 11 is in contact with the inner wall of the feeding chamber 2. When the filter needs to be cleaned, opening the box cover 4 can drive the connecting rod 9 and the guide plate 10 to move out, thereby driving the annular filter 11 to move out of the box, thereby facilitating daily cleaning and maintenance of the annular filter 11.

[0022] A fixing rod 12 is provided at the bottom of the annular filter screen 11, and the fixing rod 12 plays a fixing role. A hanging rope 13 is connected to the center of the bottom end of the fixing rod 12, and the hanging rope 13 plays the role of connecting the floating ball 14. The end of the hanging rope 13 away from the fixing rod 12 extends to the safe ink measuring chamber 3 and is connected to the floating ball 14. The diameter of the floating ball 14 is larger than the diameter of the connection between the feeding chamber 2 and the safe ink measuring chamber 3. The floating ball 14 is hollow, and the density of its material is smaller than the density of ink, and can float with the remaining amount of ink in the safe ink measuring chamber 3.

[0023] A position sensor 15 is arranged on the inner wall of one side of the bottom of the feeding chamber 2. The model of the position sensor 15 is E3Z-D62C. It adopts the principle of diffuse reflection and can detect the existence and position of an object. The position sensor 15 can detect whether the float 14 is in a safe position. A controller 16 is arranged on the outer wall of one side of the ink cartridge 1. The controller and the position sensor 15 are connected by wires. The controller 16 and the ink pump 8 are also connected by wires. When the ink in the safety ink volume chamber 3 is insufficient, the float 14 will move down with the ink liquid level, and move out of the detection range of the position sensor 15 after moving down to a certain distance. After the position sensor 15 cannot detect the float 14, it transmits a signal to the controller 16. The controller 16 controls the ink pump 8 to start, and the ink pump 8 draws the ink in the ink storage barrel 7 into the ink cartridge 1 through the ink replenishing tube 6 for replenishment. When the ink in the safety ink volume chamber 3 is sufficient, the float 14 will rise with the ink liquid level. After rising to the detection range of the position sensor 15, the controller controls the oil pump 8 to stop replenishing, thereby realizing continuous replenishment of ink in the ink cartridge 1.

[0024] A rotating shaft 17 is connected to the bottom center of the safety ink measuring chamber 3 through a bearing. The rotating shaft 17 can rotate in the safety ink measuring chamber 3. A stirring rod 18 is arranged and connected to the middle outer wall of the rotating shaft 17. The rotation of the rotating shaft 17 can drive the stirring rod 18 to rotate, thereby stirring the ink in the safety ink measuring chamber 3 to prevent the ink from solidifying. Connecting rods 19 are arranged on both sides of the bottom of the stirring rod 18. The connecting rod 19 plays a connecting role. The end of the connecting rod 19 away from the rotating shaft 17 is connected to a scraper 20. The scraper 20 is close to the bottom inner wall of the safety ink measuring chamber 3. The rotation of the rotating shaft 17 drives the connecting rod 19 and the scraper 20 to rotate. The scraper 20 rotates to scrape the inner wall of the safety ink measuring chamber 3 to avoid long-term adhesion of ink to the inner wall of the safety ink measuring chamber 3, thereby improving the cleanliness of the safety ink measuring chamber 3 and avoiding ink adhesion and accumulation affecting the discharge of the discharge port 22.

[0025] A servo motor 21 is connected to the outer wall at the center of the bottom end of the ink cartridge 1, and the output end of the servo motor 21 is connected to the rotating shaft 17. The servo motor 21 can drive the rotating shaft 17 to rotate and play a driving role. A discharge port 22 is provided at the bottom of one side of the ink cartridge 1. The discharge port 22 is connected to a conduit to supply ink to the printing roller. An electric heating wire 23 is provided around the outer wall of the safety ink measuring chamber 3. The electric heating wire 23 is electrically heated to avoid ink solidification in a low temperature environment.

[0026] Working principle: when using a continuous printing automatic ink adding mechanism, the ink pump 8 can draw the ink in the ink storage barrel 7 into the ink cartridge 1 through the ink replenishing tube 6 for replenishment. When the ink in the safety ink volume chamber 3 is insufficient, the float 14 will move down with the ink liquid level, and move out of the detection range of the position sensor 15 after moving down to a certain distance. After the position sensor 15 cannot detect the float 14, it transmits a signal to the controller 16. The controller 16 controls the ink pump 8 to start, and the ink pump 8 draws the ink in the ink storage barrel 7 into the ink cartridge 1 through the ink replenishing tube 6 for replenishment. When the ink in the safety ink volume chamber 3 is sufficient, the float 14 will rise with the ink liquid level. After rising to the detection range of the position sensor 15, the controller controls the oil pump 8 to stop replenishing, thereby realizing the continuous replenishment of ink in the ink cartridge 1. The guide plate 10 plays a diversion role to prevent the ink from directly impacting the float 3 and causing multiple vibrations. The bottom edge of the guide plate 10 is connected with an annular filter 11. The annular filter 11 plays a filtering role. By filtering and removing tiny particles and impurities in the ink, the printing ink can be prevented from being damaged. The brushed product has problems such as color difference, spots, blur, etc. The edge of the annular filter 11 is in contact with the inner wall of the feeding chamber 2. When the filter needs to be cleaned, the box cover 4 can be opened to drive the connecting rod 9 and the guide plate 10 to move out, thereby driving the annular filter 11 out of the box, so as to facilitate daily cleaning and maintenance of the annular filter 11. The servo motor 21 can drive the rotating shaft 17 to rotate and play a driving role. The rotation of the rotating shaft 17 can drive the stirring rod 18 to rotate, thereby stirring the ink in the safe ink volume chamber 3. To prevent the ink from solidifying, the rotating shaft 17 rotates to drive the connecting rod 19 and the scraper 20 to rotate. The scraper 20 rotates to scrape the inner wall of the safety ink measuring chamber 3 to prevent the ink from adhering to the inner wall of the safety ink measuring chamber 3 for a long time, thereby improving the cleanliness of the safety ink measuring chamber 3 and preventing the ink from adhering and accumulating and affecting the discharge from the discharge port 22. An electric heating wire 23 is arranged around the outer wall of the safety ink measuring chamber 3. The electric heating wire 23 is electrically heated and stirred by the stirring rod 18 to prevent the ink from solidifying in a low temperature environment.
