Description

Technical Field

[0001] The present application relates to the field of ink production equipment, and in particular to a color printing ink stirring device. Background Art

[0002] In the printing industry, the uniformity of ink mixing is directly related to the quality of printed products.

[0003] In related technologies, various components in inks, such as resins, solvents, and additives, may separate or stratify during storage. To effectively ensure the quality of printed products, these components must be thoroughly mixed through stirring to ensure the stability and performance of the ink.

[0004] The current conventional method is simply to stir the pigment in the ink evenly through the corresponding stirring equipment. However, since the pigment in the ink often precipitates, this may cause the ink to clump during storage. It is difficult to effectively break up these clumps by simply stirring the ink, and thus it is impossible to effectively ensure the normal use of the ink, which in turn affects the consistency of the ink printing effect. Summary of the Invention

[0005] The present application provides a color printing ink stirring device, the purpose of which is to optimize the production and processing process of the ink. It can not only effectively improve the stirring effect of the ink, but also effectively prevent the ink from precipitating and agglomerating, thereby effectively ensuring the stability and performance of the ink, which is conducive to ensuring the consistency of the ink printing effect, and thus effectively improving the quality of the printed product.

[0006] The present application provides a color printing ink mixing device, which adopts the following technical solution:

[0007] A color printing ink stirring device includes a stirring tank, which is hollow inside and has a partition fixed in the horizontal direction inside the stirring tank. The partition divides the inside of the stirring tank into a stirring chamber and an assembly chamber distributed upper and lower. The stirring chamber is used to fill ink, and a stirring paddle is added to the stirring chamber for stirring the ink. The stirring paddle is slidably arranged in the stirring chamber along the vertical direction. A first stirring plate and a second stirring plate are also added to the stirring chamber. The first stirring plate and the second stirring plate are located below the stirring paddle. The stirring paddle is used to drive the first stirring plate and the second stirring plate to stir the ink at the bottom of the stirring chamber.

[0008] By adopting the above technical solution, the ink is stirred by a stirring paddle, so that the components in the ink can be fully mixed. While the stirring paddle rotates in the stirring chamber, it can be raised and lowered in the vertical direction, so that the stirring paddle can stir the ink at different heights in the stirring chamber, which is beneficial to ensure that the components in the ink can be fully fused in the stirring tank, and thus can effectively improve the effect of ink fusion in the stirring tank, thereby effectively ensuring the quality of subsequent printed products; the stirring of the first stirring plate and the second stirring plate can effectively prevent the ink from precipitating and forming lumps, thereby effectively ensuring the stability and performance of the ink, which is beneficial to ensure the consistency of the ink printing effect, and thus can effectively improve the quality of the printed product. This setting method uses a stirring paddle, a first stirring plate and a second stirring plate to optimize the production and processing process of the ink, which is beneficial to improving the quality of the printed product.

[0009] Preferably, a driving motor is fastened to the top of the stirring tank, the driving end of the driving motor faces downward, and a stirring shaft is installed at the bottom of the driving motor in a vertical direction. The stirring shaft rotates under the drive of the driving motor, and the stirring shaft extends into the stirring chamber and is connected to the top of the stirring paddle. The stirring shaft is telescopically arranged in the vertical direction;

[0010] A first fixing seat is fixed to the bottom of the assembly cavity in the horizontal direction, a lifting plate is provided above the first fixing seat in the horizontal direction, a positioning seat is integrally formed on the top of the lifting plate, a second fixing seat is horizontally arranged above the lifting plate, a through hole is penetrated through the second fixing seat, a threaded barrel is integrally formed in the through hole in the vertical direction; a threaded rod is integrally formed at the bottom of the stirring paddle in the vertical direction, the threaded rod passes vertically downward through the threaded barrel and extends to the positioning seat, the threaded rod is connected to the lifting plate through the positioning seat, and the threaded rod is threadedly engaged with the threaded barrel.

[0011] By adopting the above technical solution, when it is used, the driving motor drives the stirring shaft to rotate while driving the stirring paddle to rotate through the stirring shaft. The stirring paddle rotates while driving the threaded rod to rotate in the threaded barrel. During the rotation of the threaded rod in the threaded barrel, the threaded rod can be lifted and lowered in the vertical direction. During the lifting process, the threaded rod synchronously drives the stirring paddle and the lifting plate to lift and lower, thereby enabling the stirring paddle to stir the ink at different heights in the stirring tank, which is beneficial to enhance the fusion effect of the ink in the stirring tank.

[0012] Preferably, guide rods are fixed in the vertical direction between the left and right ends of the first fixing seat and the second fixing seat, and the left and right ends of the lifting plate are respectively sleeved on the two guide rods.

[0013] By adopting the above technical solution, the two guide rods guide the lifting plate while the lifting plate is lifted in the vertical direction, thereby helping to ensure the stability of the lifting plate during the lifting process.

[0014] Preferably, the first stirring plate is located between the stirring paddle and the second stirring plate, and a connecting rod is vertically connected between the left and right ends of the first stirring plate and the lifting plate, one end of the connecting rod is integrally connected to the bottom of the first stirring plate, and the other end of the connecting rod passes through the partition and the second fixed seat in sequence and is integrally connected to the top of the lifting plate.

[0015] By adopting the above technical solution, the lifting plate is lifted and lowered in the vertical direction while driving the first stirring plate to lift and lower. During the lifting process, the first stirring plate stirs the ink at the bottom of the stirring chamber in the vertical direction, thereby effectively preventing the ink from precipitating and forming lumps, thereby effectively ensuring the stability and performance of the ink.

[0016] Preferably, the second stirring plate is located below the first stirring plate, and the second stirring plate includes a first plate body and a second plate body. The first plate body and the second plate body are distributed on the left and right sides below the first stirring plate. The first stirring plate synchronously drives the first plate body and the second plate body to slide toward or away from each other during the process of rising and falling in the vertical direction.

[0017] By adopting the above technical solution, the first plate and the second plate are used to stir the ink at the bottom of the stirring chamber horizontally, thereby effectively preventing the ink from settling and agglomerating, thereby effectively ensuring the stability and performance of the ink.

[0018] In this embodiment, the first stirring plate and the second stirring plate are used to stir the ink at the bottom of the stirring chamber in the vertical and horizontal directions, which not only allows the components in the ink to be more fully integrated, but also effectively prevents the ink from precipitating and forming lumps, thereby effectively ensuring the stability and performance of the ink, which is beneficial to improving the quality of printed products.

[0019] Preferably, the bottom of the first stirring plate is integrally connected to a driving plate, and the first plate body and the second plate body are located on the left and right sides of the driving plate. The first stirring plate drives the driving plate to rise and fall, and during the lifting process, the driving plate drives the first plate body and the second plate body to slide toward or away from each other.

[0020] By adopting the above technical solution, the first plate and the second plate are used to stir the ink at the bottom of the stirring chamber horizontally, thereby effectively preventing the ink from settling and agglomerating, thereby effectively ensuring the stability and performance of the ink.

[0022] By adopting the above technical solution, the first stirring plate simultaneously drives the driving plate downward as it descends, and the driving plate drives the first and second plates to slide away from each other during the descent. As the first stirring plate ascends, it simultaneously drives the driving plate upward as well, and during this process, the first and second plates slide toward each other, thereby achieving the effect of stirring the ink at the bottom of the stirring chamber.

[0023] Preferably, a return spring is installed between the ends of the first plate and the second plate that are away from each other and the inner wall of the stirring tank.

[0024] By adopting the above technical solution, the reset spring is used to assist the first plate and the second plate in resetting, thereby effectively ensuring the stability of the first plate and the second plate during the sliding process.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Use a stirring paddle to stir the ink so that the components in the ink can be fully mixed. While the stirring paddle rotates in the stirring chamber, it can be raised and lowered in the vertical direction, so that the stirring paddle can stir the ink at different heights in the stirring chamber, which is beneficial to ensure that the components in the ink can be fully fused in the stirring tank, which can effectively improve the effect of ink fusion in the stirring tank, thereby effectively ensuring the quality of subsequent printed products; using the first stirring plate and the second stirring plate to stir can effectively prevent the ink from precipitating and forming lumps, thereby effectively ensuring the stability and performance of the ink, which is beneficial to ensure the consistency of the ink printing effect, and thus effectively improving the quality of the printed product. This setting method uses the stirring paddle, the first stirring plate and the second stirring plate to optimize the production and processing process of the ink, which is beneficial to improving the quality of the printed product;

[0027] 2. The lifting plate is lifted and lowered vertically, driving the first stirring plate to lift and lower simultaneously.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0036] Example:

[0037] The present application discloses a color printing ink stirring device, referring to Figure 1 and Figure 2 , including a stirring tank 1, which is hollow inside. A partition 2 is welded horizontally inside the stirring tank 1, and the partition 2 is disc-shaped. The partition 2 divides the inside of the stirring tank 1 into a stirring chamber 3 and an assembly chamber 4 distributed vertically. The stirring chamber 3 is used to fill the corresponding ink, and a stirring paddle 5 for stirring the ink is added to the stirring chamber 3. The stirring paddle 5 is used to stir the ink so that the components in the ink can be fully mixed. While the stirring paddle 5 rotates in the stirring chamber 3, it can be raised and lowered in the vertical direction, so that the stirring paddle 5 can stir the ink at different heights in the stirring chamber 3, which is beneficial to ensure that the components in the ink can be fully fused in the stirring tank 1, and can effectively improve the ink fusion effect in the stirring tank 1, thereby effectively ensuring the quality of subsequent printed products.

[0038] At the same time, refer to Figure 1 and Figure 2 A first stirring plate 6 and a second stirring plate 7 are further provided in the stirring chamber 3. The first stirring plate 6 and the second stirring plate 7 are located below the stirring paddle 5. The stirring paddle 5 synchronously drives the first stirring plate 6 and the second stirring plate 7 to stir the ink at the bottom of the stirring chamber 3 during the process of fully stirring the ink. The stirring of the first stirring plate 6 and the second stirring plate 7 can effectively prevent the ink from settling and agglomerating, thereby effectively ensuring the stability and performance of the ink, which is conducive to ensuring the consistency of the ink printing effect, and thus can effectively improve the quality of the printed product.

[0039] This arrangement optimizes the production process of the ink by utilizing the stirring paddle 5 , the first stirring plate 6 and the second stirring plate 7 , which is beneficial to improving the quality of printed products.

[0040] Specifically, refer to Figure 1 and Figure 2 The top of the stirring tank 1 is fastened with a driving motor 8 by fastening bolts, the driving end of the driving motor 8 faces downward, and a stirring shaft 9 is installed at the bottom of the driving motor 8 in a vertical direction. The stirring shaft 9 rotates under the drive of the driving motor 8. The stirring shaft 9 extends into the stirring chamber 3 and is connected to the top of the stirring paddle 5.

[0041] At the same time, refer to Figure 1 and Figure 2 A first fixing seat 10 is welded horizontally at the bottom of the assembly cavity 4, a lifting plate 11 is provided horizontally above the first fixing seat 10, a disc-shaped positioning seat 12 is integrally formed on the top of the lifting plate 11, and a second fixing seat 13 is horizontally arranged above the lifting plate 11. A through hole is penetrated through the second fixing seat 13, and a threaded barrel 14 is integrally formed in the through hole along the vertical direction.

[0042] Reference Figure 1 and Figure 2 The bottom of the stirring paddle 5 is integrally formed with a threaded rod 15 in the vertical direction. The threaded rod 15 passes vertically downward through the threaded barrel 14 and extends to the positioning seat 12. The threaded rod 15 is connected to the lifting plate 11 through the positioning seat 12. The threaded rod 15 is threadedly matched with the threaded barrel 14.

[0043] During specific use, the driving motor 8 drives the stirring shaft 9 to rotate while driving the stirring paddle 5 to rotate through the stirring shaft 9. The stirring paddle 5 drives the threaded rod 15 to rotate in the threaded barrel 14. During the rotation of the threaded rod 15 in the threaded barrel 14, the threaded rod 15 can be lifted and lowered in the vertical direction. During the lifting process, the threaded rod 15 synchronously drives the stirring paddle 5 and the lifting plate 11 to lift and lower, thereby enabling the stirring paddle 5 to stir the ink at different heights in the stirring tank 1, which is beneficial to enhance the effect of ink fusion in the stirring tank 1.

[0044] The stirring shaft 9 will expand and contract as the stirring paddle 5 is raised and lowered, thereby effectively preventing the stirring shaft 9 from obstructing the raising and lowering of the stirring paddle 5 .

[0045] Further, refer to Figure 2 and Figure 3 Guide rods 16 are welded vertically between the left and right ends of the first fixing base 10 and the second fixing base 13. The left and right ends of the lifting plate 11 are respectively mounted on the two guide rods 16. As the lifting plate 11 is raised and lowered in the vertical direction, the two guide rods 16 guide the lifting plate 11, thereby helping to ensure the stability of the lifting plate 11 during the raising and lowering process.

[0046] Specifically, refer to Figure 2 and Figure 3 The first stirring plate 6 is in the shape of a rectangular parallelepiped as a whole, and is located between the stirring paddle 5 and the second stirring plate 7. A connecting rod 17 is integrally connected between the first stirring plate 6 and the lifting plate 11 in the vertical direction. One end of the connecting rod 17 is integrally connected to the bottom of the first stirring plate 6, and the other end of the connecting rod 17 passes through the partition 2 and the second fixed seat 13 in sequence and is integrally connected to the top of the lifting plate 11. The lifting plate 11 is lifted and lowered in the vertical direction, and the first stirring plate 6 is driven to lift and lower at the same time. During the lifting process, the first stirring plate 6 stirs the ink at the bottom of the stirring chamber 3 in the vertical direction, thereby effectively preventing the ink from settling and agglomerating, thereby effectively ensuring the stability and performance of the ink.

[0047] Specifically, refer to Figure 2 、 Figure 3 as well as Figure 4The second stirring plate 7 is located below the first stirring plate 6 and includes a first plate body 71 and a second plate body 72. The first plate body 71 and the second plate body 72 are located on the left and right sides below the first stirring plate 6. As the first stirring plate 6 rises and falls in the vertical direction, it synchronously drives the first plate body 71 and the second plate body 72 to slide toward or away from each other. When the first plate body 71 and the second plate body 72 slide toward or away from each other, they stir the ink at the bottom of the stirring chamber 3 in the horizontal direction, thereby effectively preventing the ink from settling and agglomerating, thereby effectively ensuring the stability and performance of the ink.

[0048] In this embodiment, the first stirring plate 6 and the second stirring plate 7 are used to stir the ink at the bottom of the stirring chamber 3 in the vertical and horizontal directions, which not only allows the components in the ink to be more fully integrated, but also effectively prevents the ink from precipitating and forming lumps, thereby effectively ensuring the stability and performance of the ink, which is beneficial to improving the quality of printed products.

[0049] Specifically, refer to Figure 2 、 Figure 3 as well as Figure 4 A driving plate 18 is welded to the bottom of the first stirring plate 6, and the first plate body 71 and the second plate body 72 are located on the left and right sides of the driving plate 18. The first stirring plate 6 is lifted and lowered in the vertical direction while synchronously driving the driving plate 18 to lift and lower. During the lifting process of the driving plate 18, the first plate body 71 and the second plate body 72 are driven to slide toward or away from each other.

[0050] The left and right ends of the driving plate 18 close to the first plate body 71 and the second plate body 72 are wedge-shaped, and the ends of the first plate body 71 and the second plate body 72 close to the driving plate 18 are also wedge-shaped. The two wedge-shaped ends of the driving plate 18 are wedge-matched with the first plate body 71 and the second plate body 72 respectively.

[0051] As the first stirring plate 6 descends, it simultaneously drives the driving plate 18 downward. During this process, the driving plate 18 drives the first plate 71 and the second plate 72 to slide away from each other. As the first stirring plate 6 ascends, it simultaneously drives the driving plate 18 upward. During this process, the first plate 71 and the second plate 72 slide toward each other, thereby achieving the effect of stirring the ink at the bottom of the stirring chamber 3.

[0052] Specifically, refer to Figure 2 and Figure 3 A return spring 19 is installed between the ends of the first plate 71 and the second plate 72 that are away from each other and the inner wall of the mixing tank 1. The return spring 19 is used to assist the first plate 71 and the second plate 72 in resetting, thereby effectively ensuring the stability of the first plate 71 and the second plate 72 during the sliding process.

[0053] The implementation principle of a color printing ink stirring device in the embodiment of the present application is as follows:

[0054] A disc-shaped partition 2 is welded horizontally within the mixing tank 1. The partition 2 divides the interior of the mixing tank 1 into a stirring chamber 3 and an assembly chamber 4, which are arranged vertically. The stirring chamber 3 is used to fill the corresponding ink, and a stirring paddle 5 is added to the stirring chamber 3 to stir the ink. The stirring paddle 5 is used to stir the ink so that the components within the ink can be fully mixed. While rotating within the stirring chamber 3, the stirring paddle 5 can be raised and lowered vertically, allowing the stirring paddle 5 to stir the ink at different heights within the stirring chamber 3. This helps ensure that the components within the ink are fully integrated within the mixing tank 1, effectively improving the ink integration effect within the mixing tank 1, and effectively ensuring the quality of subsequent printed products.

[0055] At the same time, a first stirring plate 6 and a second stirring plate 7 are further provided in the stirring chamber 3. The first stirring plate 6 and the second stirring plate 7 are located below the stirring paddle 5. The stirring paddle 5 synchronously drives the first stirring plate 6 and the second stirring plate 7 to stir the ink at the bottom of the stirring chamber 3 during the process of fully stirring the ink. The stirring of the first stirring plate 6 and the second stirring plate 7 can effectively prevent the ink from precipitating and agglomerating, thereby effectively ensuring the stability and performance of the ink, which is conducive to ensuring the consistency of the ink printing effect, and thus can effectively improve the quality of the printed product.

[0056] This arrangement optimizes the production process of the ink by utilizing the stirring paddle 5 , the first stirring plate 6 and the second stirring plate 7 , which is beneficial to improving the quality of printed products.

[0057] Specifically, the top of the mixing tank 1 is fastened with a drive motor 8 by fastening bolts, the driving end of the drive motor 8 faces downward, and a stirring shaft 9 is installed at the bottom of the drive motor 8 in a vertical direction. The stirring shaft 9 rotates under the drive of the drive motor 8. The stirring shaft 9 extends into the mixing tank 1 and is connected to the top of the stirring paddle 5.

[0058] The first stirring plate 6 is in the shape of a rectangular parallelepiped as a whole and is located between the stirring paddle 5 and the second stirring plate 7. A connecting rod 17 is vertically connected between the left and right ends of the first stirring plate 6 and the lifting plate 11. One end of the connecting rod 17 is integrally connected to the bottom of the first stirring plate 6, and the other end of the connecting rod 17 passes through the partition 2 and the second fixed seat 13 in sequence and is integrally connected to the top of the lifting plate 11. The lifting plate 11 is lifted and lowered in the vertical direction, and the first stirring plate 6 is driven to lift and lower at the same time. During the lifting process, the first stirring plate 6 stirs the ink at the bottom of the stirring chamber 3 in the vertical direction, thereby effectively preventing the ink from settling and forming lumps, thereby effectively ensuring the stability and performance of the ink.

[0059] Specifically, the second stirring plate 7 is located below the first stirring plate 6 and includes a first plate body 71 and a second plate body 72. The first plate body 71 and the second plate body 72 are distributed on the left and right sides below the first stirring plate 6. During the vertical lifting and lowering process of the first stirring plate 6, the first stirring plate 6 synchronously drives the first plate body 71 and the second plate body 72 to slide toward or away from each other. When the first plate body 71 and the second plate body 72 slide toward or away from each other, the ink at the bottom of the stirring chamber 3 is stirred horizontally, thereby effectively preventing the ink from settling and agglomerating, thereby effectively ensuring the stability and performance of the ink.

[0060] In this embodiment, the first stirring plate 6 and the second stirring plate 7 are used to stir the ink at the bottom of the stirring chamber 3 in the vertical and horizontal directions, which not only allows the components in the ink to be more fully integrated, but also effectively prevents the ink from precipitating and forming lumps, thereby effectively ensuring the stability and performance of the ink, which is beneficial to improving the quality of printed products.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
