Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing ink homogenization, in particular to an ink homogenization device for printing product manufacturing. BACKGROUND

[0002] Ink is a stable colloidal mixture composed of color pigments, dyes, binder resins, oils, additives, and fillers, etc., with specific color and fluidity. Its core function is to firmly attach graphic information to the surface of the printing material such as paper and plastic during the printing process, and to realize the replication, preservation and dissemination of information.

[0003] In the printing process, in order to ensure the uniformity of the ink layer, the ink needs to be fully homogenized. In the prior art, such as the utility model patent disclosed in the authorized announcement No. CN222239870U, a packaging printing ink uniform stirring device, although the preliminary dispersion efficiency of the ink raw material is improved by the cooperation of the stirring tank and the bidirectional stirring shaft, and the problem of ink aggregation and uneven mixing is solved, but this scheme does not effectively solve the technical difficulty that the ink is easily attached to the inner wall of the container due to high viscosity. Such wall sticking phenomenon leads to serious ink residue, not only reduces the material utilization rate, but also affects the quality of subsequent batches of ink due to ink solidification, forcing the equipment to frequently stop for cleaning, significantly reducing the production continuity and work efficiency.

[0004] The conventional countermeasures mostly adopt additional independent ink scraping mechanisms such as fixed scrapers and rotating brushes, but such additional structures often lead to increased equipment complexity, increased maintenance cost, and may introduce new risks such as foreign matter pollution or mechanical wear.

[0005] Based on the above problems, it is urgent to provide an ink homogenization device for printing product manufacturing, which utilizes the differential motion mechanism of the ink homogenization roller to achieve efficient shearing, dispersion and homogenization of the ink, while completing the self-adaptive scraping of the inner wall of the ink homogenization barrel, thereby integrating the functions of ink homogenization and scraping in one device, without the need for additional power or independent ink scraping components, improving the utilization rate of ink, ensuring the stability of ink supply, and enhancing the continuity and automation level of the device. SUMMARY

[0006] According to the problems in the background art, the present application provides an ink homogenization device for printing product manufacturing to solve the problems, and the present application will be further described.

[0007] An ink homogenization device for printing product manufacturing, comprising a support frame, a fixed frame mounted on the support frame, an ink homogenization barrel provided on the fixed frame, an ink inlet and an ink outlet provided on the ink homogenization barrel, a rotating shaft provided on the ink homogenization barrel, a servo motor mounted on the fixed frame and connected to the rotating shaft by a key, an ink homogenization roller provided on the rotating shaft, and a plurality of ink scraping assemblies distributed in the circumferential direction of the ink homogenization roller.

[0008] Preferably, the ink scraping assembly includes multiple stirring frames fixed to the ink distribution roller, a sliding frame on the stirring frame, a compression spring between the sliding frame and the stirring frame, and stirring blades on the sliding frame. The working end of the stirring blades has a blade-shaped inclined structure, and the ink on the inner wall of the ink distribution tank is scraped off by the blade-shaped inclined structure on the stirring blades.

[0009] Preferably, the mixing frame is equipped with a telescopic column, a counterweight on the telescopic column, and two sets of supports on the mixing frame. Each set of supports is hinged with a connecting rod. One end of the connecting rod is fixed to the sliding frame by bolts, and the other end of the connecting rod is fixed to the adjacent counterweight by bolts. The sliding frame is equipped with a rotating rod, and a torsion spring is provided between the rotating rod and the sliding frame. The outer wall of the rotating rod is keyed to the mixing blade. The mixing blade is equipped with an installation groove, and multiple sets of cutting plates are provided in the installation groove. A horizontal plate is provided on the cutting plate, a connecting rod is provided on the horizontal plate, a straight rod is provided on the horizontal plate, and a gear is provided on the straight rod. The sliding frame is equipped with a toothed ring, which realizes the effect of low-speed ink scraping and high-speed ink uniformity.

[0010] Preferably, the rotating rod is provided with a locking block, and the stirring rack is provided with a guide frame. The guide frame is provided with an obliquely extending guide groove structure to prevent the stirring rack from swinging when scraping ink at low speed, while allowing the stirring rack to swing freely during the high-speed ink mixing stage for ink mixing.

[0011] Preferably, the ink distribution tank is provided with a sealing cover, which is slidably connected to a fixing frame. The fixing frame is provided with a screw, a handle, and a connecting frame. The connecting frame and the sealing cover are fixedly connected by fasteners. The screw enables the sealing cover to move, which facilitates the installation and maintenance of parts inside the ink distribution tank.

[0012] Preferably, the ink-distributing roller is provided with multiple support frames, each support frame has a dividing plate, and the dividing plate has multiple flow grooves. The support frame has a base plate, and the base plate has multiple flipping plates with a unidirectional flipping structure. The support frame has a lower pressure frame, which is fixed to the flipping plates by fasteners. Cams are provided on the inner side of the sealed cover and the side wall of the ink-distributing tank. Multiple fixing rods are provided on the rotating shaft, each fixing rod having a circular groove at its end. Each circular groove contains an extrusion component, and the extrusion component has an inclined guide rail that slides with the lower pressure frame. Ball bearings are provided on the extrusion component, and the ball bearings are in contact with the cam surface. A return spring is provided between the ball bearings and the fixing rods. This design aims to apply pressure to the initially added agglomerated ink, causing it to be compressed into strips and extruded from the flow grooves of the dividing plate, achieving initial crushing and refinement, facilitating subsequent efficient shearing and homogenization.

[0013] Beneficial effects: Compared with existing technologies, this device achieves dynamic switching between stirring and scraping functions through the coordinated action of the scraping component, centrifugal counterweight, and linkage mechanism. During high-speed operation, the stirring blades automatically retract to ensure stirring efficiency, and automatically extend to complete scraping when the machine stops and decelerates. No additional power is required. The device has an ingenious structure, reliable operation, and significantly improves ink utilization and equipment automation level.

[0014] Due to the different fluid resistance experienced by the sliding frame and the stirring blade in the ink, the stirring blade deflects relative to the sliding frame. This deflection motion, through the cooperation of the straight rod, gear, and toothed ring, drives all the horizontal plates to deflect, which in turn drives the cutting plate to swing through the connecting rod, creating staggered gaps between adjacent cutting plates. When the ink passes through the gaps, it is subjected to strong shearing action, which effectively disperses the ink agglomerates and small particles.

[0015] The extrusion component moves laterally through the contact between the ball bearings and the cam. The wedge-shaped inclined surface of the extrusion component pushes the lower pressure frame downward, causing the bottom plate to move closer to the dividing plate. This compresses the internal space of the collection box and applies pressure to the agglomerated ink, causing the ink raw material to be pressed into strips and squeezed out from the flow groove of the dividing plate. This achieves the initial crushing and refining of the ink raw material, facilitating efficient shearing and homogenization by the cutting plate in the subsequent process.

Detailed Implementation

[0023] Next, combine Figures 1-6 A specific embodiment of the present invention will be described in detail below.

[0024] refer to Figure 1 and Figure 2 An ink-spreading device for printing manufacturing includes a support frame 1, on which a fixed frame 11 is mounted. An ink-spreading tank 12 is detachably connected to the fixed frame 11 via fasteners, enabling stable installation and subsequent maintenance and replacement of the ink-spreading tank 12. The ink-spreading tank 12 is a cylindrical container with an inlet 121 at the top and an outlet hopper 122 at the bottom, facilitating the addition of ink and the smooth discharge and delivery of homogenized ink to the printing mechanism. A rotating shaft 161 is connected to the inner cavity of the ink-spreading tank 12. The rotating shaft 161 is keyed to a servo motor 16 mounted on the fixed frame 11. An ink-spreading roller 18 is keyed to the outer wall of the rotating shaft 161. During operation, the ink-spreading roller 18 rotates at high speed with the rotating shaft 161, fully shearing and stirring the ink in the inner cavity of the ink-spreading tank 12 to achieve ink homogenization and improve its fluidity and ink layer consistency.

[0025] The outer peripheral wall of the ink-spreading roller 18 is provided with multiple sets of circumferentially distributed ink-scraping components. Each ink-scraping component rotates synchronously with the ink-spreading roller 18 and contacts the inner wall surface of the ink-spreading tank 12 during the ink stirring process. It mechanically scrapes off the sticky ink adhering to the inner wall, effectively reducing ink residue, improving material utilization, and reducing the cleaning frequency and downtime caused by ink accumulation.

[0026] refer to Figure 2The ink scraping assembly includes multiple circumferentially distributed stirring frames 17 fixed to the outer peripheral wall of the ink distribution roller 18. A sliding frame 22 is slidably connected to the stirring frame 17. A compression spring 221 is provided between the sliding frame 22 and the stirring frame 17 to drive the sliding frame 22 to return to its original position. A stirring blade 23 is provided on the top of the sliding frame 22. The ink distribution roller 18, stirring frame 17, sliding frame 22 and stirring blade 23 together constitute a complete stirring structure. Through the overall rotation of this stirring structure, the ink in the ink distribution tank 12 is uniformly mixed.

[0027] The working end of the stirring blade 23 has a blade-shaped inclined structure. In the initial state, the inclined surface is in contact with the inner wall of the ink tank 12 to scrape off the sticky ink adhering to the inner wall, reduce residue, and improve ink utilization.

[0028] refer to Figure 3 The mixing frame 17 is equipped with telescopic columns 24 on both the left and right side walls. The telescopic ends of the telescopic columns 24 are keyed to counterweights 2. That is, the counterweights 2 are distributed on the left and right sides of the mixing frame 17. The mixing frame 17 is provided with two sets of supports 222. Each set of supports 222 is hinged with a connecting rod 21. The connecting rods 21 on the two sets of supports 222 are arranged symmetrically in a figure-eight shape. One end of each connecting rod 21 is fixed to the sliding frame 22 by bolts, and the other end of the connecting rod 21 is fixed to the adjacent counterweight 2 by bolts, forming a linkage mechanism that drives the sliding frame 22 to rise and fall by the displacement of the counterweights 2.

[0029] In the initial state, the device is stationary, the counterweight 2 is located at a low position on the side wall of the stirring frame 17, and the telescopic column 24 is in a compressed state. Through the transmission relationship of the connecting rod 21, the sliding frame 22 is in a high position, the compression spring 221 is in a relaxed state, and the working end of the stirring blade 23 is in close contact with the inner wall of the ink tank 12.

[0030] During operation, ink to be processed is added through the feed inlet 121. The servo motor 16 is started, driving the rotating shaft 161 to rotate, which in turn drives the ink distribution roller 18, stirring frame 17, sliding frame 22, and stirring blade 23 to rotate synchronously. In the initial stage of startup, the rotation speed gradually increases, and the counterweight 2 moves outward and upward along the telescopic column 24 under the action of centrifugal force, and the telescopic end of the telescopic column 24 is stretched. This movement is transmitted through the connecting rod 21, pulling the sliding frame 22 to retract downward against the elastic force of the compression spring 221, causing the stirring blade 23 to gradually detach from the inner wall of the ink distribution tank 12, so that it completely enters the ink. This avoids overheating or wear caused by continuous friction between the stirring blade 23 and the inner wall of the ink distribution tank 12 during high-speed rotation, ensuring a stable and efficient stirring process.

[0031] When the rotation speed reaches the set value and tends to stabilize, the counterweight 2 is fixed in position, and the sliding frame 22 and the stirring blade 23 remain in a stable working position to continuously homogenize the ink.

[0032] After the ink mixing process is completed, the servo motor 16 is turned off, the rotation speed of the shaft 161 gradually decreases, and the centrifugal force decreases accordingly. Under the action of gravity and the restoring force of the telescopic column 24, the counterweight 2 returns to its original position inward and downward, and the telescopic column 24 is gradually compressed. Through the reverse transmission of the connecting rod 21, the sliding frame 22 is pushed to move upward, and the compression spring 221 gradually releases its stored energy, causing the working end of the stirring blade 23 to re-adhere to the inner wall of the ink mixing tank 12, completing the scraping action of the adhering ink.

[0033] The entire ink scraping process ends when the rotating shaft 161 comes to a complete stop. The homogenized ink is then discharged through the discharge hopper 122, achieving efficient and low-residue continuous operation.

[0034] This device achieves dynamic switching between stirring and scraping functions through the coordinated action of centrifugal counterweight and linkage mechanism: the stirring blades automatically retract during high-speed operation to ensure stirring efficiency, and automatically extend to complete scraping when the machine stops and decelerates. It requires no additional power, has an ingenious structure, is reliable in operation, and significantly improves ink utilization and equipment automation level.

[0035] To enhance the shear dispersion effect on high-viscosity inks and further improve mixing uniformity, this device adds a dynamic shear structure to the sliding frame 22. Specifically, refer to... Figure 3 A rotating rod 3 is rotatably connected to the sliding frame 22. The two ends of the rotating rod 3 pass through the sliding frame and extend outward. A torsion spring 33 is provided between the rotating rod 3 and the sliding frame 22 to provide a reset torque. The outer wall of the rotating rod 3 is keyed to the stirring blade 23, so that the stirring blade 23 rotates synchronously with it.

[0036] refer to Figure 3 The stirring blade 23 is a rectangular structure with a mounting groove in the middle, and multiple sets of vertically arranged cutting plates 36 are rotatably connected in the mounting groove. In the initial state, the cutting plates 36 maintain a vertical posture, and the left and right ends of each cutting plate 36 are respectively keyed to a horizontal plate 38. The corresponding ends of all horizontal plates 38 on the same side are hinged to a connecting rod 37, thus forming a linkage swing structure, so that all cutting plates 36 can deflect synchronously.

[0037] refer to Figure 3 A straight rod 381 is keyed to the outer wall of the bottom horizontal plate 38. The straight rod 381 passes through the side wall of the stirring blade 23 and extends to the outside. A gear 35 is keyed to its end. A toothed ring 34 that meshes with the gear 35 is keyed to the sliding frame 22.

[0038] During device operation, when the stirring blade 23 detaches from the inner wall of the ink tank and enters the ink zone, due to the different fluid resistance experienced by the sliding frame 22 and the stirring blade 23 in the ink, the stirring blade 23 deflects relative to the sliding frame 22, causing the rotating rod 3 to rotate, and the torsion spring 33 deforms and stores energy. This deflection motion is transmitted to the gear 35 through the straight rod 381, causing it to roll and rotate around the toothed ring 34, thereby driving all the horizontal plates 38 to deflect synchronously. Through the connecting rod 37, all the cutting plates 36 swing in unison, forming staggered gaps between adjacent cutting plates 36. When the ink passes through the gaps, it is subjected to strong shearing action, effectively breaking up ink agglomerates and small particles.

[0039] When the counterweight 2, the sliding frame 22 and the stirring blade 23 are kept in a stable working position and rotate with the ink roller 18, the stirring blade 23 and the sliding frame 22 tend to be balanced by forces. When the gear 35 and the toothed ring 34 are stably meshed, the deflection angle of the cutting plate 36 is constant. At this time, the shearing mechanism enters the steady-state stirring mode and continues to maintain the uniform flow of ink.

[0040] After the ink mixing process is completed, the servo motor 16 is turned off, and the rotation speed of the rotating shaft 161 gradually decreases. Under the action of the torsion spring 33, the rotating rod 3 is driven to reverse and reset. The gear 35 and the toothed ring 34 mesh in opposite directions, driving the straight rod 381 to reverse. The reverse rotation of the straight rod 381 drives the horizontal plate 38 connected to it to reverse synchronously. Under the action of the connecting rod 37, the other horizontal plates 38 are driven to reverse and reset, thereby achieving the effect of synchronous reset of all cutting plates 36.

[0041] This device achieves both shearing and stirring effects through a dynamic shearing structure, significantly improving ink processing efficiency and material utilization.

[0042] refer to Figure 3 The rotating rod 3 is keyed to both ends of the left and right ends with locking blocks 32. The top of the stirring frame 17 is fixed with a guide frame 31 that corresponds one-to-one with the locking blocks 32. The guide frame 31 is provided with a guide groove structure that extends obliquely.

[0043] Before the device is started, the stirring blade 23 is in the position of extending to scrape ink, and the locking block 32 is located in the top area of ​​the guide groove of the guide frame 31. The guide groove of the guide frame 31 limits the locking block 32 here, realizing mechanical locking in the initial state.

[0044] In the initial stage of startup, as the rotational speed increases, the stirring blade 23 retracts, and the locking block 32 slides downward along the inclined guide groove of the guide frame 31. Since the guide groove is an inclined structure, no constraint on the rotational direction of the locking block 32 is applied during this process, allowing the locking block 32 to drive the rotating rod 3 to rotate freely, thereby ensuring the normal deflection response of the dynamic shear structure on the sliding frame 22.

[0045] As the ink mixing operation ends and the rotation speed decreases, the stirring blade 23 extends outward again under the action of the reset mechanism to perform the ink scraping action. The locking block 32 slides upward along the guide groove of the guide frame 31 and finally resets to the top limit area of ​​the guide groove of the guide frame 31, locking the stirring blade 23 and preventing the stirring blade 23 from deflecting due to the huge resistance of the ink under low-speed mixing. In this state, the working end of the top of the stirring blade 23 is attached to the inner wall of the ink mixing tank 12 to complete the scraping action of the adhering ink.

[0046] To facilitate the installation and maintenance of the components involved in the aforementioned shearing and scraping actions, please refer to... Figure 1 The side wall of the ink tank 12 is detachably connected to a sealing cover 13. The sealing cover 13 is slidably connected to the fixing frame 11. A screw 15 is rotated on the side of the fixing frame 11 near the sealing cover 13. A handle is provided at the end of the screw 15. External force rotates the handle to drive the screw 15 to rotate. A connecting frame 14 is threadedly connected to the screw 15. The connecting frame 14 is fixed to the outer wall of the sealing cover 13 by fasteners.

[0047] The external force rotates the handle to drive the screw 15 to rotate, which in turn drives the connecting frame 14 to move, causing the sealing cover 13 to move synchronously. This achieves the effect of closing and separating the sealing cover 13 from the ink tank 12. When the sealing cover 13 is in close contact with the ink tank 12, the sealing cover 13 and the ink tank 12 can be locked by fasteners to keep the device stable in the working state.

[0048] Based on common sense, the ink to be processed is in a high viscosity and paste state and exhibits agglomeration. The shearing efficiency of the cutting plate 36 alone is low for this agglomerated ink. Therefore, this device adds an extrusion structure to the ink distribution roller 18 to achieve pretreatment of the agglomerated ink, which facilitates subsequent shearing and uniform dispersion.

[0049] refer to Figure 4 , Figure 5 and Figure 6 This extrusion structure includes multiple detachable support frames 4 mounted on the outer wall of the ink-spreading roller 18. The support frames 4 and the stirring frame 17 are arranged alternately. A dividing plate 46 is fixed to the support frame 4 by fasteners. The dividing plate 46 is an arc-shaped plate with multiple evenly distributed flow grooves for the discharge of ink after extrusion. A bottom plate 48 is embedded and slidably connected to the support frame 4. The support frame 4, the dividing plate 46 and the bottom plate 48 together form a collection box structure with an internal cavity.

[0050] Multiple evenly distributed flipping plates 481 are connected to the base plate 48. The flipping plates 481 have a one-way flipping structure, which only allows ink to enter the inner cavity of the collection box structure from the outside, preventing backflow.

[0051] refer to Figure 4 , Figure 5 andFigure 6 The support frame 4 has a sliding lower pressure frame 47 embedded in both side walls. The lower pressure frame 47 is fixed to the flip plate 481 by fasteners to achieve linkage. The inner side of the closed cover 13 and the side wall of the ink tank 12 are provided with cams 41. Multiple fixing rods 42 are keyed to the rotating shaft 161. The ends of the fixing rods 42 are all opened with circular grooves. Extrusion parts 45 are slidably connected in the horizontal through the circular grooves. One end of the extrusion part 45 is provided with an inclined guide rail. This inclined guide rail is slidably connected to the end of the lower pressure frame 47 to drive the lower pressure frame 47 to move in a direction. The other end of the extrusion part 45 is connected to a ball 44. The ball 44 is pressed and engaged with the surface of the adjacent cam 41 to realize the lateral movement of the extrusion part 45. A return spring 43 is provided between the ball 44 and the fixing rod 42.

[0052] During operation, as the ink-spreading roller 18 rotates, the collection box structure rotates synchronously. The flipping plate 481 flips upon contact with the agglomerated ink, allowing the ink to enter the inner cavity. When the ball bearing 44 contacts the cam 41, the cam 41 pushes the ball bearing 44 towards the support frame 4, causing the extruder 45 to move laterally and compressing the return spring 43. The inclined guide rail of the extruder 45 pushes the lower pressure frame 47 downwards, causing the base plate 48 to move closer to the dividing plate 46, compressing the internal space of the collection box and applying pressure to the agglomerated ink material, pressing it into strips and extruding it from the flow groove of the dividing plate 46. This achieves initial crushing and refining of the ink material, facilitating subsequent efficient shearing and homogenization by the cutting plate 36.

[0053] When the ball 44 disengages from the working area of ​​the cam 41, the return spring 43 releases its elastic force, pushing the ball 44 and the pressing component 45 to move in the opposite direction to reset. As the pressing component 45 gradually resets, it drives the lower pressure frame 47 to reset via the inclined guide rail of the pressing component 45, preparing for the next working cycle.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
