Description

Technical Field

[0001] This application relates to the field of printing technology, and more specifically, to a device for preventing ink from solidifying in a printing press cartridge. Background Technology

[0002] Because the pigments in the ink cartridge are poorly dispersed in the binder, and the relative density of the pigments or fillers is too low, sedimentation is likely to occur after long-term storage. To ensure that the pigments and binder are thoroughly and evenly mixed again, the ink can be re-stirred. Existing technology CN114347648A provides a printing press ink cartridge anti-coagulation device. A drive belt on the feed roller rotates a shaft A, which in turn rotates a stirring blade to agitate the ink inside the printing cartridge, preventing coagulation. Shaft A drives bevel gear A, which in turn drives bevel gear B, causing a rotating rod to rotate and generate electricity. A battery stores the electricity generated by the generator to provide power for the internal ink anti-coagulation mechanism after the feed roller stops working.

[0003] However, this device has its shortcomings. When in use, the ink has a high concentration, causing it to adhere to the inner wall of the ink cartridge. Although the device has a stirring blade to stir the ink, the stirring range is limited, making it difficult to treat the ink adhering to the inner wall of the ink cartridge. This leads to ink clumping and affects the performance. Therefore, we propose an anti-coagulation device for printing press ink cartridges. Summary of the Invention

[0022] 3. Beneficial effects

[0023] Compared to existing technologies, the advantages of this application are:

[0024] 1. By setting up an ink cartridge adhesion impact mechanism, the T-shaped piston can be driven to reciprocate when the ink cartridge rotates, thereby drawing the ink in the middle of the ink cartridge into the suction tube. Then, it can be sprayed through the spray tube onto the inner walls of both ends of the ink cartridge, which can effectively impact and knock down the ink adhering to the inner walls of both ends of the ink cartridge, thereby preventing ink clumping and solidification.

[0025] 2. By setting up a cartridge drive mechanism, the cartridge can be rotated back and forth during use, which allows the ink inside to slosh around, thus washing away the ink adhering to the inner wall of the cartridge. This further improves the treatment of the ink adhering to the inner wall of the cartridge, thereby enhancing the practicality of the device.

[0026] 3. By setting up an ink stirring mechanism, the drive rod will contact the fixed frame when the ink cartridge rotates, so that the drive rod can move into the ink cartridge. Under the action of the guide head, the stirring blade with the transmission groove can rotate, thereby mixing the ink in the ink cartridge and preventing the ink from solidifying.

[0034] Please see Figure 1-6 This application provides a technical solution:

[0035] A printing press ink cartridge anti-coagulation device includes a fixed frame 1, an ink pressing roller 2 rotatably mounted at the bottom of the fixed frame 1, and an ink cartridge 3 rotatably connected to the fixed frame 1.

[0036] The ink cartridge drive mechanism 4 is fixedly mounted on the mounting bracket 1.

[0037] The ink cartridge adhesion impact mechanism 5 is connected to the inner wall of the ink cartridge 3. The ink cartridge adhesion impact mechanism 5 includes two suction tubes 501. One end of the suction tube is connected to a spray tube with multiple spray nozzles. The suction tube can suck in the ink in the ink cartridge and spray it out through the spray tube. The spray tube is set towards the inner wall of the ink cartridge, which can wash the ink on the inner wall of the ink cartridge down and prevent it from condensing on the inner wall of the ink cartridge.

[0038] Multiple ink stirring mechanisms 6 are rotatably connected and run through the inner walls of the ink cartridge 3.

[0039] Specifically, an ink outlet tube 301 is rotatably connected to one end of the outer wall of the ink cartridge 3, and the other end of the outer wall of the ink outlet tube 301 extends through the inner wall of the fixing frame 1 to the outside and is fixedly connected thereto. The outer end of the ink outlet tube 301 is connected to the ink pressure roller 2.

[0040] Furthermore, the ink cartridge drive mechanism 4 includes a motor 401, which is fixedly connected to the outer wall of the mounting bracket 1. The output end of the motor 401 extends through the outer wall of the mounting bracket 1 to the inner side and is fixedly connected to a universal joint 402.

[0041] In this embodiment, the universal joint 402 is telescopic. Since the ink cartridge 3 is rotatably mounted on the fixed frame, during actual rotation, the universal joint 402 drives the gear 406 to rotate, so that the gear 406 rotates around the arc plate 302 and always meshes with the rack 303, so that the ink cartridge 3 can rotate relative to the fixed frame.

[0042] Furthermore, during the rotation of the ink cartridge, the gear 406 first meshes with the outer wall of the arc plate 302. When the ink cartridge rotates to the point where the gear 406 meshes with the rack 303 at the end of the arc plate 302, the arc plate 302 continues to rotate, causing the gear 406 to mesh with the rack 302 on the inner side of the arc of the arc plate 302, thus changing the rotation direction of the ink cartridge 3 and ensuring that the ink in the ink cartridge 3 is fully mixed.

[0043] Universal joint 402 can drive gear 406 to rotate and also adjust its position.

[0044] Furthermore, a rotating shaft 403 is fixedly connected to the other end of the universal joint 402. A limit seat 404 is rotatably connected to the outer wall of the rotating shaft 403. Limit rods 405 are slidably fitted through both ends of the limit seat 404. The limit rods 405 are fixedly connected to the fixed frame 1.

[0045] In this embodiment, the limiting rod 405 enables the limiting seat 404 to move stably up and down.

[0046] Furthermore, an arc-shaped plate 302 is fixedly connected to the outer wall of one end of the ink cartridge 3 near the ink cartridge drive mechanism 4, and a rack 303 is fixedly connected to the outer wall of the arc-shaped plate 302.

[0047] A gear 406 is fixedly connected to the outer wall of the end of the rotating shaft 403 near the ink cartridge 3. The gear 406 meshes with the rack 303 for transmission.

[0048] In this embodiment, the rack 303 enables the ink cartridge 3 to reciprocate.

[0049] Furthermore, two suction tubes 501 are fixedly connected to the inner wall of the ink cartridge 3, and a liquid guide tube 502 is fixedly connected to the inner end of the suction tube 501. Multiple spray tubes 503 are fixedly connected to the other end of the liquid guide tube 502. An inlet is opened at the inner end of the suction tube 501.

[0050] In this embodiment, a one-way valve is installed in both the inlet and outlet of the suction tube 501.

[0051] Furthermore, the ink cartridge attachment impact mechanism 5 also includes a threaded rod 504. One end of the threaded rod 504 extends through the inner wall of the ink cartridge 3 to the outside and is rotatably connected to it. A transmission wheel 505 is fixedly connected to the outer end of the threaded rod 504.

[0052] A ring rack 101 is fixedly connected to the outer wall of the fixed frame 1, and the ring rack 101 is engaged with the transmission wheel 505 for transmission.

[0053] In this embodiment, the ring rack 101 drives the ink cartridge attachment impact mechanism 5.

[0054] It is worth noting that a T-shaped piston 506 is threadedly connected to the outer wall of one end of the threaded rod 504 inside the ink cartridge 3. The outer walls of both ends of the T-shaped piston 506 are slidably fitted with the inner wall of the suction tube 501.

[0055] In this embodiment, the T-shaped piston 506 performs the function of reciprocating suction.

[0056] It is worth noting that the ink stirring mechanism 6 includes a stirring blade 601. The stirring blade 601 has a hollow structure in the middle. The stirring blade 601 is rotatably connected to the inner wall of the ink cartridge 3. A drive rod 602 is slidably fitted on the inner wall of the stirring blade 601. One end of the drive rod 602 extends through the inner wall of the ink cartridge 3 to the outside and is slidably fitted thereto.

[0057] In this embodiment, the drive rod 602 can realize the rotation of the stirring blade 601.

[0058] In addition, a tension spring 603 is fixedly connected to one end of the drive rod 602 inside the stirring blade 601, and the other end of the tension spring 603 is fixedly connected to the inner wall of the ink cartridge 3. The outer end of the drive rod 602 is V-shaped, and a guide head 604 is fixedly connected to the inner end of the drive rod 602. The inner wall of the stirring blade 601 has a spiral structure with a transmission groove 605. The outer wall of the guide head 604 is slidably engaged with the inner wall of the transmission groove 605, and the outer end of the drive rod 602 is in movable contact with the outer wall of the fixed frame 1.

[0059] In this embodiment, the tension spring 603 performs the resetting function of the drive rod 602.

[0060] When it is necessary to agitate the ink in the ink cartridge 3 of the printing press, the motor 401 can drive the connected universal joint 402 to rotate, thereby driving the gear 406 connected to the rotating shaft 403 to rotate. The gear 406 can drive the arc plate 302 connected to the rack 303 to rotate, which will drive the ink cartridge 3 to rotate. Since the outer wall of the arc plate 302 is connected and fixed with the rack 303 in a ring shape, when the gear 406 meshes with the rack 303 at both ends of the arc plate 302, it will cause the gear 406 to move up and down, so that the limit seat 404 will slide on the limit rod 405, thereby allowing the gear 406 to drive the ink cartridge 3 to reciprocate.

[0061] While the ink cartridge 3 is rotating, the transmission wheel 505 connected to the threaded rod 504 will mesh with the ring rack 101, thereby driving the threaded rod 504 to rotate. The threaded rod 504 will drive the T-type piston 506 to move, thereby drawing the ink in the middle of the ink cartridge 3 into the suction tube 501 through the liquid inlet, and then squeezing it through the liquid guide tube 502 to the spray tube 503, spraying it onto the inner walls of both ends of the ink cartridge 3, washing off the attached ink and mixing it.

[0062] Simultaneously, when the drive rod 602 contacts the inner wall of the fixed frame 1, due to the V-shaped structure at the lower end of the drive rod 602, it will move into the stirring blade 601 when in contact with the fixed frame 1. At this time, the guide head 604 on the drive rod 602 will slide in the transmission groove 605, thereby causing the stirring blade 601 to rotate and stir the ink. When the drive rod 602 is not in contact with the fixed frame 1, the tension spring 603 will drive the drive rod 602 to move out, achieving automatic reset. The mixed ink can be guided into the ink roller 2 through the ink outlet pipe 301 for printing.
