Description

Technical Field

[0001] This utility model belongs to the field of printing technology, and more specifically, relates to an auxiliary ink supply and stirring device for printing presses. Background Technology

[0002] The auxiliary ink mixing device of a printing press is a core component ensuring high-precision and high-security printing, primarily used to achieve uniform mixing and stable delivery of ink. In some special printing processes, high-viscosity anti-counterfeiting inks such as masking inks and matte inks are required. These inks contain metal particles, resin bases, and special solvents, demanding stringent requirements for dispersion uniformity and anti-settling properties. Existing devices typically consist of a mixing mechanism, ink delivery pipes, and a control unit. The mixing mechanism often employs a single-shaft driven paddle or spiral blade mechanical design, using rotational shear force to achieve initial ink mixing.

[0003] However, existing stirring structures, due to their unidirectional shear force, cannot effectively break up agglomerated particles in high-viscosity inks, making it difficult to create multidirectional fluid disturbances. This leads to stratification of the resin and solvent in the ink, resulting in sedimentation and clumping at the bottom of the ink can. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary ink mixing device for printing presses, which aims to improve the mixing effect of ink.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an auxiliary ink supply and stirring device for a printing press, comprising:

[0006] Ink reservoir;

[0007] A rotating sleeve is vertically mounted inside the ink reservoir, and multiple transverse stirring blades are evenly distributed on its outer peripheral wall along the vertical direction.

[0008] Multiple rotating horizontal shafts are all horizontally rotatably mounted on the rotating sleeve and arranged sequentially in the vertical direction. Multiple vertical stirring blades are evenly distributed in the horizontal direction on the outer peripheral wall of the rotating horizontal shaft.

[0009] A drive assembly, disposed on the ink reservoir and connected to the rotating sleeve, is used to drive the rotating sleeve to rotate, thereby causing the transverse stirring blades to transversely stir the ink; and

[0010] A linkage component is disposed inside the rotating sleeve and is connected to the rotating horizontal shaft for transmission; when the rotating sleeve rotates, the linkage component drives the rotating horizontal shaft to rotate, so that the vertical stirring blades vertically stir the ink.

[0011] In one possible implementation, the linkage component includes:

[0012] A fixed axis is vertically fixed inside the ink reservoir. The fixed axis is located inside the rotating sleeve and is coaxial with the rotating sleeve.

[0013] Multiple first bevel gears are fixedly mounted on the fixed shaft and correspond one-to-one with the rotating horizontal shaft;

[0014] Multiple second bevel gears are fixedly mounted on the rotating horizontal shaft and correspond one-to-one with the rotating horizontal shaft; each second bevel gear meshes with a corresponding first bevel gear.

[0015] When the rotating sleeve rotates, each of the second bevel gears rotates on its own axis while rotating around the corresponding first bevel gear.

[0016] In one possible implementation, one end of the fixed shaft is fixed to the ink reservoir, and the other end is rotatably connected to the rotating sleeve.

[0017] In one possible implementation, the driving component includes:

[0018] The drive motor is fixedly mounted on the ink reservoir, and its output end is connected to the rotating sleeve.

[0019] In one possible implementation, a drive shaft is coaxially fixed on the rotating sleeve, the drive shaft is rotatably mounted on the ink reservoir, and the end of the drive shaft opposite to the rotating sleeve is connected to the output end of the drive motor.

[0020] In one possible implementation, the horizontal axis of rotation and the horizontal stirring blades are arranged alternately in the vertical direction.

[0021] In one possible implementation, there are two horizontal rotating shafts at the same height, symmetrically arranged on the rotating sleeve; there are two horizontal stirring blades at the same height, symmetrically arranged on the rotating sleeve; the horizontal stirring blades and the horizontal rotating shafts are located on different sides of the rotating sleeve.

[0022] In one possible implementation, the transverse stirring blades are evenly distributed with through holes in the horizontal direction for ink to pass through, and the through holes are opened at an angle.

[0023] In one possible implementation, the vertical stirring blades on two adjacent horizontal axes of rotation are staggered.

[0024] In one possible implementation, a scraper is horizontally fixed at the bottom end of the rotating sleeve, and the scraper abuts against the inner bottom wall of the ink reservoir.

[0025] The auxiliary ink supply and stirring device for printing presses provided by this utility model has the following advantages compared with the prior art: It uses a rotating sleeve to drive the transverse stirring blades to perform horizontal rotational shearing, while simultaneously using a linkage component to drive the rotating horizontal shaft and its vertical stirring blades to generate vertical stirring, forming a multi-directional composite fluid motion. The synergistic effect of horizontal and vertical stirring breaks the limitations of single-direction shearing force, enhances the dispersion uniformity of metal particles and resin base materials in the ink, effectively suppresses stratification, and ensures thorough mixing of various components in the ink, significantly improving the ink uniformity.

[0032] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0033] It should be further explained that the accompanying drawings and embodiments of this utility model mainly describe the concept of this utility model. Based on this concept, some specific forms and settings of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of this utility model, they can implement the above-mentioned specific forms and settings in a well-known manner.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The auxiliary ink supply and stirring device for a printing press provided by this utility model will now be described. The auxiliary ink supply and stirring device for a printing press includes an ink reservoir 1, a rotating sleeve 2, multiple rotating horizontal shafts 3, a drive assembly, and a linkage assembly. The rotating sleeve 2 is vertically rotatable within the ink reservoir 1, and its outer peripheral wall is evenly distributed with multiple horizontal stirring blades 21 along the vertical direction. The multiple rotating horizontal shafts 3 are horizontally rotatable on the rotating sleeve 2 and are arranged sequentially along the vertical direction. The outer peripheral wall of each rotating horizontal shaft 3 is evenly distributed with multiple vertical stirring blades 31 along the horizontal direction.

[0035] A drive assembly is mounted on the ink reservoir 1 and is connected to the rotating sleeve 2 for driving the rotating sleeve 2 to rotate, thereby causing the transverse stirring blades 21 to stir the ink transversely. A linkage assembly is mounted inside the rotating sleeve 2 and is connected to the rotating horizontal shaft 3 for driving. When the rotating sleeve 2 rotates, the linkage assembly drives the rotating horizontal shaft 3 to rotate, thereby causing the vertical stirring blades 31 to stir the ink vertically.

[0036] The drive assembly is connected to the rotating sleeve 2. When the drive assembly is activated, it drives the rotating sleeve 2 to rotate vertically within the ink reservoir 1. Multiple transverse stirring blades 21 rotate accordingly, creating transverse shear force and fluid disturbance in the ink, thus horizontally stirring the ink, initially breaking up larger agglomerates and promoting horizontal mixing. As the rotating sleeve 2 rotates, the linkage assembly is activated, transmitting the rotation of the rotating sleeve 2 to the rotating horizontal shaft 3, causing the horizontal shaft 3 to rotate horizontally around its own axis. Multiple vertical stirring blades 31 rotate with the horizontal shaft 3, generating vertical shear force and fluid disturbance in the ink, thus vertically stirring the ink.

[0037] The coordinated operation of the horizontal stirring blade 21 and the vertical stirring blade 31 creates multidirectional fluid disturbance and shear force. While the horizontal stirring blade 21 mixes the ink horizontally, the vertical stirring blade 31 stirs the ink vertically. The two blades intersect and complement each other, effectively breaking down the structure of agglomerated particles in high-viscosity ink, avoiding the stratification problem of resin and solvent, and ensuring that the various components in the ink are fully mixed. This significantly improves the uniformity of the ink and meets the requirements for ink dispersion uniformity and anti-settling properties.

[0038] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The linkage assembly includes a fixed shaft 41, multiple first bevel gears 42, and multiple second bevel gears 43. The fixed shaft 41 is vertically fixed inside the ink reservoir 1, located inside the rotating sleeve 2, and coaxial with the rotating sleeve 2. Each of the multiple first bevel gears 42 is fixedly mounted on the fixed shaft 41 and corresponds one-to-one with the rotating horizontal axis 3. Each of the multiple second bevel gears 43 is fixedly mounted on the rotating horizontal axis 3 and corresponds one-to-one with the rotating horizontal axis 3. Each second bevel gear 43 meshes with a corresponding first bevel gear 42. When the rotating sleeve 2 rotates, each second bevel gear 43 rotates around its corresponding first bevel gear 42 while simultaneously rotating on its own axis.

[0039] The fixed shaft 41 is vertically fixed inside the ink reservoir 1 and coaxial with the rotating sleeve 2, providing stable support and transmission reference for the entire linkage assembly. When the rotating sleeve 2 rotates, it drives the second bevel gear 43 mounted on the rotating horizontal shaft 3. Since each second bevel gear 43 meshes with a corresponding first bevel gear 42, the second bevel gear 43 can rotate on its own axis while revolving around the first bevel gear 42. This meshing transmission method can transmit the rotation of the rotating sleeve 2 to the rotating horizontal shaft 3, ensuring that the rotating horizontal shaft 3 can rotate stably, thereby driving the vertical stirring blades 31 to vertically stir the ink.

[0040] In some embodiments, see Figure 3 One end of the fixed shaft 41 is fixed to the ink reservoir 1, and the other end is rotatably connected to the rotating sleeve 2. This ensures the stability of the fixed shaft 41 within the ink reservoir 1 while allowing the rotating sleeve 2 to rotate freely around the fixed shaft 41. During the rotation of the rotating sleeve 2, the rotatable connection with the fixed shaft 41 reduces the frictional resistance between the two, ensuring smoother rotation of the rotating sleeve 2.

[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The drive assembly includes a drive motor 51. The drive motor 51 is fixedly mounted on the ink reservoir 1, and its output end is connected to the rotating sleeve 2.

[0042] The drive motor 51 provides a stable power source for the rotating sleeve 2, driving it to rotate continuously. During the printing process, the ink needs to remain in a uniformly mixed state. The stable operation of the drive motor 51 ensures that the transverse stirring blades 21 continuously stir the ink laterally. Simultaneously, the drive motor 51 can adjust its output speed according to the characteristics of the ink and the requirements of the printing process to adapt to different stirring intensities, ensuring sufficient and stable power for the stirring device under various operating conditions. This allows the stirring work to continue uninterrupted, thereby guaranteeing the uniformity and stability of the ink.

[0043] In some embodiments, see Figure 4 A drive shaft 52 is coaxially fixed on the rotating sleeve 2. The drive shaft 52 is rotatably mounted on the ink storage tank 1. The end of the drive shaft 52 away from the rotating sleeve 2 is connected to the output end of the drive motor 51.

[0044] When the drive motor 51 is running at high speed, the transmission shaft 52 can effectively transmit power to the rotating sleeve 2, while avoiding the unstable rotation of the rotating sleeve 2 due to vibration, thereby ensuring that the stirring effect of the transverse stirring blade 21 on the ink is stable and reliable, and improving the operational stability of the entire stirring device.

[0045] In some embodiments, see Figure 2 The rotating horizontal shaft 3 and the horizontal stirring blades 21 are arranged alternately in the vertical direction, avoiding interference between them during the stirring process. When the rotating sleeve 2 rotates, the horizontal stirring blades 21 and the vertical stirring blades 31 on the rotating horizontal shaft 3 can fully exert their stirring effect within their respective spatial ranges.

[0046] When the horizontal stirring blade 21 stirs the ink in a horizontal plane, the rotating horizontal shaft 3 and its vertical stirring blade 31 will not obstruct it, so that the ink can be fully stirred in both the horizontal and vertical directions, which expands the stirring range, enhances the stirring effect, and further improves the uniformity of ink mixing.

[0047] In some embodiments, see Figure 2 and Figure 3 There are two horizontal rotating shafts 3 at the same height, symmetrically arranged on the rotating sleeve 2. There are also two horizontal stirring blades 21 at the same height, symmetrically arranged on the rotating sleeve 2. The horizontal stirring blades 21 and the horizontal rotating shafts 3 are located on different sides of the rotating sleeve 2.

[0048] When the rotating sleeve 2 rotates, the symmetrically arranged transverse stirring blades 21 and the vertical stirring blades 31 on the rotating horizontal shaft 3 can stir the ink from different angles, avoiding uneven ink mixing caused by uneven stirring force. At the same time, the arrangement on different sides further expands the stirring range, allowing the ink to be stirred more comprehensively and evenly in both the horizontal and vertical directions, significantly improving the uniformity and stability of the ink.

[0049] In some embodiments, as shown in the figure, the transverse stirring blade 21 has through holes 211 evenly distributed in the horizontal direction for ink to pass through, and the through holes 211 are opened at an angle.

[0050] When the transverse stirring blades 21 rotate, the ink, under the action of centrifugal force and blade rotation, flows directionally through the inclined through-holes 211. The ink enters from one side of the inclined through-holes 211 and exits at a certain angle from the other side, forming a localized ink circulation. This circulation accelerates ink mixing, allowing areas that were originally mixing slowly to exchange and mix more quickly with other parts of the ink, thus improving stirring efficiency. Simultaneously, the inclined through-holes 211 also exert a certain shear force on the ink, further helping to break up agglomerated particles in the ink, enhancing the stirring effect, and contributing to improved ink uniformity.

[0051] In some embodiments, see Figure 2 and Figure 3 The vertical stirring blades 31 on the two adjacent horizontal rotating axes 3 are staggered.

[0052] As the horizontal axis 3 rotates, the staggered vertical stirring blades 31 can cover a larger vertical space. The stirring areas of the vertical stirring blades 31 on the upper horizontal axis 3 and the stirring areas of the vertical stirring blades 31 on the lower horizontal axis 3 complement each other, avoiding blind spots in the vertical stirring process. This staggered distribution allows the ink to be stirred more comprehensively and finely in the vertical direction, further improving the mixing uniformity of the ink in the vertical direction.

[0053] In some embodiments, see Figure 2 and Figure 3 A scraper 6 is fixedly installed horizontally at the bottom end of the rotating sleeve 2, and the scraper 6 abuts against the inner bottom wall of the ink storage tank 1.

[0054] As the rotating sleeve 2 rotates, the scraper 6 rotates accordingly, scraping up the ink deposited on the bottom wall of the ink reservoir 1. For metal particles, resin base materials, etc., that are prone to settle at the bottom of the reservoir in high-viscosity inks, the scraper 6 can scrape them off, allowing them to re-participate in the ink mixing process. This prevents these deposits from clumping at the bottom of the reservoir, maintains the uniformity of the ink composition, helps ensure the stability of the ink during storage and transportation, avoids ink quality degradation due to sedimentation, and thus ensures high precision and high safety in printing.

[0055] In summary, the auxiliary ink supply and stirring device for printing presses provided by this invention, compared with existing technologies, addresses the issue that traditional single-axis stirring devices rely on shear force in a single direction. Under laminar flow, ink is prone to agglomeration of metal particles and stratification of resin solvent, leading to irreversible sedimentation at the bottom of the container. This invention, through the coordinated work of the transverse stirring blades 21 and the vertical stirring blades 31, creates multi-directional fluid disturbance and shear force. While the transverse stirring blades 21 mix the ink horizontally, the vertical stirring blades 31 stir the ink vertically. The two work together, effectively breaking down the agglomerated particles in high-viscosity inks, avoiding the stratification problem of resin and solvent, ensuring thorough mixing of various components in the ink, significantly improving ink uniformity, and meeting the requirements for ink dispersion uniformity and anti-settling properties.
