Description

Technical Field

[0001] This invention relates to the field of ink production technology, specifically a high-precision impurity filtration device for ink production. Background Technology

[0002] Ink is a liquid or paste mixture composed of colorants, solvents, and additives. It is used in printing, writing, inkjet printing, and various marking fields. Ink not only determines the color saturation, clarity, and durability of the output image, but also affects the working performance and lifespan of printing equipment. The ink production process usually includes multiple steps such as batching, dispersion, grinding, blending, filtration, and filling.

[0003] In the ink formulation process, pigments or dyes are mixed with solvents, resins, and other functional additives in a specific ratio. Then, high-speed dispersion and fine grinding are used to achieve a uniform submicron-level distribution of pigment particles. Finally, the viscosity, surface tension, and other physical properties are adjusted and then filtered to remove impurities before the finished product is filled. Therefore, the filtration process is particularly critical. Traditional filtration devices mostly use a single filter screen for mechanical interception filtration. The structure is simple, and it mainly relies on the size of the filter screen pores to retain solid particles. The filter screen is prone to clogging, which reduces the filtration speed and production efficiency. It also requires frequent shutdowns for cleaning or replacement of the filter screen, affecting continuous operation. Summary of the Invention

[0004] The purpose of this invention is to provide a high-precision impurity filtration device for ink production, so as to solve the problem of inconvenience in using existing impurity filtration devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-precision impurity filtration device for ink production includes a filter tank and further includes:

[0007] The filter tank has a partition inside, which divides the inner cavity of the filter tank into a sedimentation chamber and a cleaning chamber. A sliding groove is provided on the outside of the filter tank. A driving block is provided inside the sliding groove. A rotating rod is provided on the driving block. A movable frame is provided between the two rotating rods. The movable frame is formed by connecting two square frames. A connecting pipe is provided inside the movable frame. A filter box is provided on the connecting pipe. A filter screen is provided inside the filter box. A rack is provided at the top of the filter tank. Gears that mesh with the rack are provided on the outside of the rotating rods.

[0008] The filter box has a fixed cylinder, a movable plate rotatably mounted on its top, a pressure plate mounted on the movable plate, a guide plate with a guide groove on the side wall of the movable frame, a connecting pipe at one end of the rotating rod, a connecting plate inside the movable frame, the rotating rod being connected to the inside of the connecting pipe through the connecting plate, a fixed cylinder outside the filter tank, filter chambers on both sides inside the fixed cylinder, a sealing plate inside the filter chamber, an inlet pipe between the two filter chambers, the inlet pipe being connected to the connecting pipe, and a transmission plate at the center inside the fixed cylinder.

[0009] The driving mechanism, connected to the driving block, can drive the driving block to slide along the sliding groove. The driving block drives the movable frame to move along the inside of the sedimentation chamber. The filter box filters impurities by cooperating with the filter screen. The movable plate pushes out the filtered ink by driving the pressure plate to move downward.

[0010] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0011] In one alternative embodiment: the driving mechanism includes a lead screw, a transmission belt, and a motor. The lead screw is disposed inside the sliding groove, and a lead screw nut that cooperates with the lead screw is disposed on the driving block. One end of each of the two lead screws extends out of the filter groove and is provided with a pulley. A transmission belt is disposed between the two pulleys. A protective cover is disposed outside the filter groove, and a motor is disposed inside the protective cover. The rotating end of the motor is connected to the lead screw.

[0012] In one alternative: a protective box is provided on the top of the filter tank, and a connecting groove is provided on the side wall of the protective box, through which the rotating rod passes and slides.

[0013] In one alternative: a top plate is rotatably provided on the top of the transmission plate, and pressure rods are provided on both outer sides of the transmission plate.

[0014] In one alternative: the sealing plate has a through hole, the sealing plate is provided with a limit plate on the outside, the fixed cylinder is provided with a discharge cylinder on its side wall, the liquid inlet pipe is provided with a liquid passage pipe, and the connecting pipe is connected to the liquid inlet pipe through the liquid passage pipe.

[0015] In one alternative: the filter tank is provided with a fixing frame and a fixing plate on the outside, the fixing frame is provided with a crossbeam, and the crossbeam is provided with multiple spray pipes.

[0016] In one alternative: a telescopic plate is slidably disposed on the fixed plate, a pressure groove is provided at one end of the telescopic plate, a fixing ring is provided on the side wall of the movable frame, the fixing ring is slidably sleeved on the outside of the rotating rod, and a pressure block is provided on the fixing ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The high-precision impurity filtration device in ink production performs secondary pressure filtration of ink through a filter box and a fixed cylinder, achieving efficient and automated separation and collection of ink impurities. The filter screen in the filter box performs primary interception of large particles of impurities. The movable plate presses down to force the pre-filtered ink into the fixed cylinder. The drive mechanism pushes the sealing plate through the top plate and pressure rod, applying pressure to the ink in the filter chamber, forcing it to pass through the more precise filter screen on the sealing plate, ensuring that fine particles and impurities are effectively removed, thereby achieving high-precision filtration and improving filtration accuracy and efficiency. The filter box is rinsed through multiple spray nozzles to avoid filter screen clogging and ensure production continuity. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] like Figure 1-8 As shown, a high-precision impurity filtration device for ink production, provided in one embodiment of the present invention, includes a filter tank 1, and further includes:

[0031] The movable frame 4 is a rectangular filter tank 1 filled with ink to be filtered. A vertical partition 3 divides the filter tank 1 into a sedimentation chamber 101 and a cleaning chamber 102. The ink to be filtered undergoes initial sedimentation in the sedimentation chamber 101. Sliding grooves 103 are provided on both sides of the filter tank 1. A driving block 14 is slidably mounted inside the sliding groove 103, and a rotating rod 16 is rotatably mounted on the driving block 14. A movable frame 4 is positioned between the two rotating rods 16. A connecting pipe 31 is installed inside the movable frame 4, and a filter box 5 is mounted on the connecting pipe 31. A filter screen 501 is installed inside the filter box 5. A rack 18 is mounted on the top of the filter tank 1, and a gear 17 meshing with the rack 18 is mounted on the outside of the rotating rods 16. The movable frame 4 is formed by two rectangular frames elastically connected by an elastic element. The connecting pipe 31 can generate [something] between the two rectangular frames. A certain degree of sliding ensures that the opening of the filter box 5 always faces upward, facilitating the filtration of the inflowing ink through the filter screen 501. When the movable frame 4 moves above the sedimentation chamber 101, the gear 17 drives the rotating rod 16 to rotate through meshing with the rack 18. The rotating rod 16 drives the movable frame 4 to rotate as a whole through the transmission key 161 on it. The two sets of filter boxes 5 are immersed downward into the ink in the sedimentation chamber 101 in sequence. The ink flows into the interior of the filter box 5, and the impurities are trapped by the filter screen 501. When the movable frame 4 moves to the top of the cleaning chamber 102, the telescopic plate 24 set on the outside of the cleaning chamber 102 is pressed and squeezes the fixing ring 401, so that the two square frames are pressed and locked. The connecting pipe 31 inside the movable frame 4 is pressed, so that the movable frame 4 can drive the connecting pipe 31 and the filter box 5 to rotate. The opening of the filter box 5 rotates to face downward, and the impurities trapped inside are poured into the cleaning chamber 102, completing the cleaning and collection of impurities.

[0032] The filter box 5 has a fixed cylinder 2. A movable plate 7 is rotatably mounted on the top of the filter box 5 via a torsion spring. Under the action of the torsion spring, the movable plate 7 is initially kept horizontal. A pressure plate 701 is provided on the movable plate 7, and a counterweight is provided inside the pressure plate 701 to increase the downward pressure. A guide plate 6 is provided on the side wall of the movable frame 4, and a guide groove 601 is provided on the guide plate 6. A connecting pipe 15 is provided at one end of the rotating rod 16. A connecting plate 32 is provided inside the movable frame 4. The rotating rod 16 is connected to the connecting pipe 31 through the connecting plate 32. A fixed cylinder 2 is provided outside the filter tank 1. Filter chambers 201 are provided on both sides inside the fixed cylinder 2. A sealing plate 36 is provided inside the filter chambers 201. An inlet pipe 10 is provided between the two filter chambers 201. The inlet pipe 10 is connected to the connecting pipe 15. A transmission plate 8 is provided at the center of the fixed cylinder 2.

[0033] like Figure 1-2 As shown, when filter cartridge 5 moves downwards to immerse ink (corresponding to...) Figure 1 At position A), the ink buoyancy overcomes the torsion spring force, lifting the movable plate 7 upwards and separating it from the top opening of the filter box 5, allowing ink to flow into the filter box 5. When the filter box 5 is removed from the ink, the guide plate 6 locks the movable plate 7, preventing it from immediately resetting under the action of the torsion spring; when the filter box 5 moves to the highest position of the movable frame 4 (corresponding to...), Figure 1 (Position B) The movable plate 7 moves down along the guide groove 601 under the gravity of the counterweight and is tightly pressed against the top opening of the filter box 5. As the movable plate 7 is pressed down, the ink inside the filter box 5 is squeezed and flows from the inside of the filter box 5 through the connecting pipe 31 and the connecting plate 32 into the rotating rod 16, and then flows through the connecting pipe 15 and the liquid inlet pipe 10 and finally enters the filter chamber 201 of the fixed cylinder 2 to complete the secondary filtration and collection of the ink.

[0034] The driving mechanism is connected to the driving block 14 and can drive the driving block 14 to slide along the sliding groove 103. The driving block 14 drives the movable frame 4 to move along the inside of the sedimentation chamber 101. The filter box 5 filters impurities by cooperating with the filter screen 501. The movable plate 7 pushes out the filtered ink by driving the pressure plate 701 to move downward.

[0035] like Figure 1-4 As shown, in a preferred embodiment of the present invention, the driving mechanism includes a lead screw 19, a transmission belt 21, and a motor 22. The lead screw 19 is disposed inside the sliding groove 103, and a lead screw nut that cooperates with the lead screw 19 is disposed on the driving block 14. One end of each of the two lead screws 19 extends out of the filter groove 1 and is provided with a pulley 20. A transmission belt 21 is disposed between the two pulleys 20. A protective cover 11 is disposed outside the filter groove 1, and a motor 22 is disposed inside the protective cover 11. The rotating end of the motor 22 is connected to the lead screw 19. The motor 22 drives the lead screw 19 to rotate, and drives the driving block 14 to slide along the sliding groove 103 through the lead screw nut, thereby realizing the reciprocating movement of the movable frame 4 and the filter box 5 between the sedimentation chamber 101 and the cleaning chamber 102.

[0036] like Figure 5 As shown, a scraper 30 is provided between the two rotating rods 16. The scraper 30 is slidably disposed inside the filter tank 1 and can scrape the impurities at the bottom of the sedimentation chamber 101 and scrape the impurities into the waste box 33. A baffle 34 is rotatably disposed at the opening of the waste box 33. The baffle 34 can be rotated inward to open when impurities are pushed in, and then reset and close under its own weight or the action of the elastic element, effectively preventing impurities from flowing back or overflowing.

[0037] like Figure 1-2As shown, in a preferred embodiment of the present invention, a protective box 12 is provided on the top of the filter tank 1, and a connecting groove 121 is provided on the side wall of the protective box 12. The rotating rod 16 passes through the connecting groove 121 and slides with it to prevent external foreign objects from interfering with the transmission components and to ensure that the rotating rod 16 runs stably on a predetermined trajectory.

[0038] like Figure 1-8 As shown, in a preferred embodiment of the present invention, a top plate 35 is rotatably mounted on the top of the transmission plate 8, and pressure rods 38 are provided on both sides of the outer side of the transmission plate 8. The top plate 35 is elastically mounted by a torsion spring. When the drive block 14 slides above the fixed cylinder 2, it will squeeze the top plate 35, and then push the sealing plate 36 to move in the filter chamber 201 through the transmission plate 8 and the pressure rods 38. A fine filter screen is provided on the sealing plate 36. The pressurized ink passes through the fine filter screen to achieve secondary filtration, and then flows into the liquid collection chamber surrounded by the transmission plate 8 and the sealing plate 36, and is finally discharged through the discharge cylinder 9.

[0039] like Figure 1-8 As shown, in a preferred embodiment of the present invention, the sealing plate 36 is provided with a through hole 361, and a limiting plate 37 is provided on the outside of the sealing plate 36. The limiting plate 37 makes the sealing plate 36 slide only along the inner wall of the fixed cylinder 2. The side wall of the fixed cylinder 2 is provided with a discharge cylinder 9, and the liquid inlet pipe 10 is provided with a liquid outlet pipe 13. The connecting pipe 15 is flexibly connected to the liquid inlet pipe 10 through the liquid outlet pipe 13 to adapt to the positional changes caused by the movement of the movable frame 4.

[0040] like Figure 1-3 As shown, in a preferred embodiment of the present invention, the filter tank 1 is provided with a fixing frame 25 and a fixing plate 23. The fixing frame 25 is provided with a crossbeam 26, and the crossbeam 26 is provided with a plurality of spray pipes 27. The spray pipes 27 are connected to a water source or cleaning liquid, which can spray and clean the movable frame 4 and the filter box 5 that have moved to the top of the cleaning chamber 102, and wash away residual impurities.

[0041] like Figure 1-5 As shown, in a preferred embodiment of the present invention, a telescopic plate 24 is slidably disposed on the fixed plate 23, and a pressure groove 241 is provided at one end of the telescopic plate 24. A fixing ring 401 is provided on the side wall of the movable frame 4. The fixing ring 401 is slidably sleeved on the outside of the rotating rod 16. A pressure block 402 is provided on the fixing ring 401. When the movable frame 4 moves above the cleaning chamber 102, the telescopic plate 24 presses the fixing ring 401 tightly through the cooperation of the pressure groove 241 and the pressure block 402, thereby locking the movable frame 4 as a whole.

[0042] The above embodiments of the present invention provide a high-precision impurity filtration device for ink production. The ink to be filtered is transported to the sedimentation chamber 101 of the filter tank 1. The ink level needs to reach a height that allows the filter box 5 to be submerged. Before starting the device, all components are in their initial positions, with the movable frame 4 located at one end of the sedimentation chamber 101. The motor 22 drives two lead screws 19 to rotate via the transmission belt 21. The drive block 14 moves along the sliding groove 103, causing the movable frame 4 and the filter box 5 to slowly move from one end of the sedimentation chamber 101 to the other end. When the filter box 5 is immersed in the ink, the ink flows into the interior of the filter box 5, and the impurities are trapped by the filter screen 501, completing the primary filtration. When the filter box 5 moves out of the ink level, the guide plate 6 will lock the movable plate 7 to prevent it from closing immediately. As the movable frame 4 continues to move to the highest point, the movable plate 7 moves down along the guide groove 601 under the gravity of the counterweight, finally pressing tightly together. At the top of the filter box 5, the downward pressing action of the movable plate 7 squeezes the ink that has undergone primary filtration inside the filter box 5, forcing it into the filter chambers 201 on both sides of the fixed cylinder 2. The drive block 14 squeezes and pushes the top plate 35 on the transmission plate 8. The top plate 35 pushes the sealing plate 36 to move in the filter chamber 201 through the transmission plate 8 and the pressure rods 38 on both sides, applying pressure to the ink in the chamber and forcing the ink to pass through the fine filter screen on the sealing plate 36 to achieve secondary fine filtration. The filtered clean ink enters the central liquid collection chamber formed by the transmission plate 8 and the sealing plate 36, and is finally discharged through the discharge cylinder 9 to be collected as the final product. When the movable frame 4 moves above the cleaning chamber 102, the telescopic plate 24 on the fixed plate 23 presses the fixing ring 401, and the entire movable frame 4 is locked. The meshing of the gear 17 and the rack 18 causes the rotating rod 16 and the movable frame 4 to flip, and the opening of the filter box 5 turns downward to complete the cleaning of impurities.

[0043] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
