Abstract

This utility model relates to the technical field of color printing ink processing equipment, and in particular to a color printing ink stirring device for preventing sedimentation. It includes a frame, a controller, a stirring chamber, a liquid outlet pipe, a solenoid valve, a sealing cover, and pull rods. The controller is installed on the front of the frame, and the stirring chamber is fixedly connected inside the frame. The liquid outlet pipe is fixedly connected to the front of the stirring chamber, and a solenoid valve is installed on the liquid outlet pipe. A sealing cover is placed on top of the stirring chamber, and multiple pull rods are fixedly connected to the top of the sealing cover. The stirring frame creates shear convection in the middle layer of ink, preventing stratification of the middle layer concentration.

Description

Technical Field

[0001] This utility model relates to the technical field of color printing ink processing equipment, and in particular to a color printing ink stirring device for preventing sedimentation. Background Technology

[0002] Color printing ink is a functional material composed of pigments, resins, solvents, and other components. It is widely used for color printing on various substrates such as paper, plastics, and metals. Its core function is to form clear and stable color prints. Its color reproduction, adhesion, and durability directly determine the quality of the final printed product.

[0003] However, pigment particles in ink are prone to sedimentation when left to stand or insufficiently stirred, especially accumulating at the bottom of the stirring device and the corners of the tank, forming clumps that are difficult to disperse. Currently, most common ink stirring devices use a single-layer stirring paddle structure, which limits the stirring action to the upper part of the tank and makes it difficult to effectively stir the bottom area. This results in the sediment not being fully stirred up, causing uneven ink concentration between the upper and lower layers, which seriously affects the printing effect and product consistency.

[0004] Therefore, it is necessary to design a color printing ink stirring device that prevents sedimentation. Utility Model Content

[0005] In order to overcome the shortcomings of existing ink stirring devices that rely on a single-layer stirring paddle and cannot stir the bottom, resulting in uneven ink concentration and affecting printing quality, this utility model provides a color printing ink stirring device that prevents sedimentation.

[0006] The technical solution of this utility model is: a color printing ink stirring device for preventing sedimentation, comprising a frame, a controller, a stirring chamber, an outlet pipe, a solenoid valve, a sealing cover, a pull rod, an inlet pipe, a motor, a snap-fit ​​block, a main shaft, protrusions, a stirring frame, and a spiral plate. The controller is installed on the front side of the frame, the stirring chamber is fixedly connected inside the frame, the outlet pipe is fixedly connected to the front side of the stirring chamber, the solenoid valve is installed on the outlet pipe, the sealing cover is placed on the top of the stirring chamber, multiple pull rods are fixedly connected to the top of the sealing cover, the inlet pipe is fixedly connected to the top of the sealing cover, the motor is installed on the top of the sealing cover, the solenoid valve and the motor are electrically connected to the controller, the snap-fit ​​block is connected to the output shaft of the motor, the snap-fit ​​block has multiple slots, the main shaft is placed at the bottom of the stirring chamber, multiple protrusions are fixedly connected to the upper part of the main shaft, the protrusions are all snapped into the corresponding slots, the stirring frame is fixedly connected to the outside of the main shaft, and the spiral plate is fixedly connected to the lower part of the outside of the main shaft.

[0007] Furthermore, it also includes connecting rods, sliding rods, and scrapers. Multiple connecting rods are fixedly connected to the outside of the mixing rack, and multiple sliding rods are slidably connected inside each connecting rod. The sliding rods all pass through the connecting rods, and scrapers are fixedly connected to the outside of the multiple sliding rods on the same connecting rod.

[0008] Furthermore, it also includes leaf springs, with leaf springs fixedly connected to the outside of the connecting rods, and the sliding rods fixedly connected to the leaf springs.

[0009] Furthermore, it also includes mounting blocks, screw rods, locking blocks, and nuts. Multiple mounting blocks are fixedly connected to the top of the frame, and screw rods are rotatably connected inside each mounting block. Multiple locking blocks are fixedly connected to the outside of the sealing cover, and screw rods are locked into their corresponding locking blocks. Nuts are threaded onto each screw rod.

[0010] Furthermore, it also includes observation windows, with multiple observation windows fixedly connected to the front side of the mixing chamber.

[0011] Furthermore, the observation window is made of transparent material.

[0012] Beneficial effects: 1. The stirring rack forms shear convection for the middle layer ink, preventing the middle layer concentration from separating. The spiral plate rotates against the bottom of the tank, transporting the sediment at the bottom of the tank upward to the middle layer, avoiding the accumulation of ink sediment in the bottom blind area. This solves the problem that existing ink stirring devices rely on a single layer of stirring paddle, which is difficult to stir the bottom, resulting in uneven ink concentration at the top and bottom, affecting printing quality.

[0013] 2. This utility model, by setting a connecting rod, a sliding rod, a scraper, and a leaf spring, allows the scraper to slide flexibly within the connecting rod. Combined with the elastic pressure of the leaf spring, it automatically adapts to the minute dimensional errors of the inner wall of the mixing chamber, ensuring that the scraper always fits tightly against the chamber wall, preventing solidification and sedimentation on the wall surface. No manual adjustment is required, thus improving the flexibility and durability of the device.

[0014] 3. This utility model, by setting up an installation block, a spiral rod, a locking block, and a nut, allows for quick disassembly and assembly. During cleaning, simply loosen the nut and rotate the spiral rod to prevent it from getting stuck in the locking block, then pull out the sealing cover and remove the main shaft and stirring components. This greatly shortens maintenance time and significantly improves work efficiency. Attached Figure Description

[0028] Example: A color printing ink stirring device to prevent sedimentation, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 , Figure 11 and Figure 12As shown, the assembly includes a frame 1, a controller 2, a mixing chamber 3, an observation window 301, an outlet pipe 4, a solenoid valve 5, a sealing cover 6, a pull rod 7, an inlet pipe 8, a motor 9, a snap-fit ​​block 10, a main shaft 11, a protrusion 12, a mixing rack 13, and a spiral plate 14. The controller 2 is mounted on the front of the frame 1. The mixing chamber 3 is welded inside the frame 1. Two observation windows 301 are welded to the front of the mixing chamber 3. The observation windows 301 are made of transparent material, such as acrylic, to allow operators to observe the ink volume and mixing status in the mixing chamber 3 in real time. An outlet pipe 4 is welded to the front of the mixing chamber 3, and a solenoid valve 5 is installed on the outlet pipe 4. A sealing cover 6 is placed on top of the mixing chamber 3 to prevent ink leakage or evaporation during mixing. Two pull rods 7 are welded to the top of the sealing cover 6, symmetrically distributed on both sides. An inlet pipe 7 is welded to the top of the sealing cover 6. A motor 9 is installed on the top of the liquid pipe 8 and the sealing cap 6. The solenoid valve 5 and the motor 9 are electrically connected to the controller 2. A snap-fit ​​block 10 is connected to the output shaft of the motor 9. The snap-fit ​​block 10 has two symmetrically distributed slots 1001. A main shaft 11 is placed at the bottom of the mixing chamber 3. Two symmetrically distributed protrusions 12 are welded to the upper part of the main shaft 11. The protrusions 12 are inserted into the corresponding slots 1001. A stirring frame 13 is welded to the outside of the main shaft 11. It forms a shearing and pushing effect on the ink in the middle layer of the mixing chamber 3, breaks the static balance of the ink, and allows the pigment particles to be initially mixed with the resin and solvent. This avoids the formation of local concentration differences in the middle layer ink due to static standing. A spiral plate 14 is welded to the lower part of the outside of the main shaft 11. It can transport the sediment at the bottom of the chamber upward to the middle layer and avoid the accumulation of ink sediment in the bottom blind area.

[0029] like Figure 7 , Figure 8 and Figure 9 As shown, it also includes connecting rods 15, sliding rods 16, scrapers 17 and leaf springs 18. Six connecting rods 15 distributed axially are welded to the outside of the stirring frame 13. Four sliding rods 16 are slidably connected inside each connecting rod 15. The sliding rods 16 all pass through the connecting rods 15. Scrapers 17 are welded between the four sliding rods 16 on the same connecting rod 15. Leaf springs 18 are welded to the outside of each connecting rod 15. The sliding rods 16 are all welded to the leaf springs 18.

[0030] like Figure 1 , Figure 11 and Figure 12 As shown, it also includes mounting blocks 19, screw rods 20, locking blocks 21 and nuts 22. Two mounting blocks 19 are welded to the top of the frame 1 in a symmetrical arrangement. The screw rods 20 are rotatably connected inside the mounting blocks 19. Two locking blocks 21 are welded to the outside of the sealing cover 6 in a symmetrical arrangement. The screw rods 20 are locked into the corresponding locking blocks 21. Nuts 22 are threaded onto the screw rods 20.

[0031] When this device is needed to stir ink, the operator first injects the color printing ink raw material into the stirring chamber 3 through the liquid inlet pipe 8. During the injection process, the operator can observe the liquid level in real time through the transparent observation window 301. The injection is stopped when the amount of ink reaches the appropriate volume in the stirring chamber 3. Then, the motor 9 is started through the controller 2. The output shaft of the motor 9 rotates and drives the locking block 10 to rotate synchronously. Since the locking groove 1001 of the locking block 10 is engaged with the protrusion 12 of the main shaft 11, the main shaft 11 drives the stirring frame 13 to rotate synchronously, breaking the static balance of the ink and allowing the pigment particles to be initially mixed with the resin and solvent. At the same time, the spiral plate 14 also rotates, generating upward conveying power, scraping up the pigment particles deposited at the bottom of the stirring chamber 3 and conveying them to the middle stirring area, forming a convection circulation with the middle ink, preventing sedimentation and accumulation at the bottom of the stirring chamber 3.

[0032] The leaf spring 18 is always in a slightly compressed state, providing continuous outward elastic pressure to the slide rod 16, pushing the slide rod 16 to slide flexibly within the connecting rod 15, so that the scraper 17 fits tightly against the inner wall of the mixing chamber 3. The scraper 17 can scrape off the ink residue adhering to the inner wall of the mixing chamber 3 in real time, preventing the ink from forming solidified sediment on the inner wall of the mixing chamber 3. At the same time, the scraped ink is sent back to the mixing area to ensure the overall ink concentration is uniform, further enhancing the anti-settling effect. During the mixing process, the operator can observe the ink mixing status in the mixing chamber 3 in real time through the observation window 301 (e.g., whether the pigment particles are completely dispersed, whether there is local sedimentation, whether the ink flow is uniform, etc.). When the ink is thoroughly stirred (without sediment and consistent concentration) and needs to be discharged, the operator activates the solenoid valve 5 via controller 2 and controls the output shaft of motor 9 to reverse. After the solenoid valve 5 is energized, the valve core opens, and the reverse rotation of motor 9 switches the conveying direction of spiral plate 14 from upward to downward, generating a downward thrust. Under the action of its own gravity and the downward push of spiral plate 14, the ink is discharged directionally along the liquid outlet pipe 4 for subsequent color printing operations. After the discharge is completed, controller 2 shuts off motor 9 and solenoid valve 5.

[0033] When cleaning components such as the mixing frame 13 and the spiral plate 14 is required, rotate the nut 22 sequentially to move it upward along the spiral rod 20 until the nut 22 no longer presses against the locking block 21. Then, rotate the spiral rod 20 outward to release it from the locking block 21, thus releasing the sealing cover 6. Hold the pull rod 7 and pull the sealing cover 6 upward. The sealing cover 6 drives the motor 9 and the locking block 10 to move out simultaneously. At this time, the protrusion 12 separates from the slot 1001. The mixing frame 13 and the spiral plate 14 can then be taken out through the main shaft 11 for cleaning. After cleaning, put the main shaft 11 back into the mixing chamber 3 to reset it. Replace the sealing cover 6 and make the protrusion 12 realign with the slot 1001 and fit into it. Ensure that the locking block 10 and the main shaft 11 form a precise connection. Then, rotate the spiral rod 20 in the opposite direction to align it with the locking block 21 again and lock it in. Finally, tighten the nut 22 to press the sealing cover 6 tightly and fix it on the top of the mixing chamber 3, thus completing the device reset and completing the use of this device.
