Description

Technical Field

[0001] This utility model relates to the field of ink production technology, and more specifically to a raw material proportioning device for ink production. Background Technology

[0002] The proportioning of raw materials in ink production is a crucial step in ensuring product quality and performance. Raw material proportioning devices precisely control the ratio of each component to meet the ink's performance requirements, such as hue, flowability, and drying properties. Ink raw materials are generally divided into four categories: pigments, binders, solvents, and additives. Each raw material needs to be quantitatively fed into mixing equipment for blending.

[0003] Traditional proportioning devices have some limitations in practical applications, mainly in the compatibility between raw material delivery and container design. For example, the design of traditional connection structures can lead to raw material residues in the delivery path, which may subtly affect the proportioning accuracy over time and increase the difficulty of cleaning and maintenance. Especially in ink production scenarios with strict cleanliness requirements, such as food packaging and pharmaceutical packaging, residues may become potential risk points, requiring systematic optimization to achieve higher standards of process control. Utility Model Content

[0004] To address the technical problems existing in the ink raw material proportioning of the prior art, the first aspect of this utility model proposes a raw material proportioning device for ink production, comprising:

[0005] Multiple raw material storage components, each of which is used to hold a target raw material;

[0006] A quantitative conveying component, the first end of which is connected to the raw material storage component;

[0007] A mixing container is provided with multiple raw material inlets and a stirring device is also provided inside the mixing container;

[0008] A plug is detachably connected to the raw material inlet, and the second end of the plug is connected to the second end of the metering conveying component;

[0009] The mixing container has a ferromagnetic ring around its raw material inlet. The plug is attracted to the ferromagnetic ring, and when the plug is in contact with the ferromagnetic ring, the insertion tube of the plug extends into the interior of the mixing container.

[0010] Preferably, the plug includes a connecting tube and a connecting ring, the connecting tube is located on a first side of the connecting ring, the insertion tube is located on a second side of the connecting ring, the end face of the second side of the connecting ring is provided with a magnetic ring, and the inner side of the magnetic ring is provided with a sealing ring.

[0011] Preferably, the outer diameter of the magnetic ring is the same as the outer diameter of the ferromagnetic ring, the inner diameter of the sealing ring is the same as the inner diameter of the ferromagnetic ring, and there is a gap between the magnetic ring and the sealing ring.

[0012] Preferably, the thickness of the sealing ring is greater than the thickness of the magnetic ring, and when the magnetic ring and the ferromagnetic ring are attracted, the sealing ring contacts the ferromagnetic ring before the magnetic ring.

[0025] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0026] Combination Figure 1 As shown, this utility model proposes a raw material proportioning device for ink production, including multiple raw material storage components 10, a quantitative conveying component 20, a mixing container 30, and a plug 40. Each of the multiple raw material storage components 10 is used to place a target raw material, such as a pigment storage tank, a binder storage tank, a solvent storage tank, or an additive storage tank.

[0027] The first end of the quantitative conveying component 20 is connected to the raw material storage component 10, and the second end is connected to the plug 40. It is responsible for quantitatively conveying the material in the raw material storage component 10 to the plug 40.

[0028] The quantitative conveying component 20 includes multiple conveying branches 21, each of which is equipped with an independent weighing component. The weighing components of different conveying branches 21 have different weighing ranges.

[0029] Combination Figure 1 As shown in the figure, there are two conveying branches 21. The first conveying branch is equipped with a weighing component 231 with a first range, and the second conveying branch is equipped with a weighing component 232 with a second range.

[0030] In this way, it can adapt to different order requirements. For example, small orders can use weighing components with small ranges, while large orders can use weighing components with large ranges.

[0031] In optional embodiments, the weighing component includes one or more of a high-precision electronic scale (for powdered raw materials), a flow meter (for liquid raw materials), a microbalance, or a syringe (for liquid additives).

[0032] Combination Figure 2 As shown, the mixing container 30 is provided with multiple raw material inlets 34, which correspond to the feeding of colorants, binders, solvents and additives, respectively. The mixing container 30 is also provided with a stirring device for mixing the materials fed into the mixing container 30.

[0033] Optionally, the stirring device includes a drive component 31 and a stirrer 31 located inside the mixing container 30.

[0034] Furthermore, the plug 40 is detachably connected to the raw material inlet 34.

[0035] Specifically, a ferromagnetic ring 33 is provided around the raw material inlet 34 of the mixing container 30. The plug 40 is attracted to the ferromagnetic ring 33, and when the plug 40 is attached to the ferromagnetic ring 33, the insertion tube 45 of the plug 40 extends into the interior of the mixing container 30.

[0036] Thus, the plug 40 is detachably connected to the mixing container 30 by magnetic attraction, which facilitates the quick removal of the plug 40 to complete the cleaning of the entire conveying channel and the plug itself. At the same time, there are no dead corners in the connection between the plug 40 and the raw material inlet 34, which can avoid residue.

[0037] In an optional embodiment, the plug 40 includes a connecting tube 41 and a connecting ring 42. The connecting tube 41 is located on the first side of the connecting ring 42, and the insertion tube 45 is located on the second side of the connecting ring 42. A magnetic ring 43 is provided on the end face of the second side of the connecting ring 42, and a sealing ring 44 is provided on the inner side of the magnetic ring 43.

[0038] In an optional embodiment, the attractive force between the ferromagnetic ring 33 and the magnetic ring 43 is 5 to 15 N.

[0039] Combination Figure 3 and Figure 4 As shown, when adding raw materials into the mixing container 30, the insertion tube 45 is inserted into the raw material inlet 34. At this time, the lower part of the insertion tube 45 extends into the mixing container 30, and the raw materials can directly enter the mixing container 30. The inner wall of the insertion tube 45 is smooth and there is no seam with the mixing container 30, so there is no residue. At the same time, the connecting ring 42 and the ferromagnetic ring 33 are magnetically attracted and fixed. On the basis of stable connection, it is conducive to quick insertion and removal, and convenient to clean the insertion tube 45 and the conveying branch pipe 21.

[0040] Combination Figure 4 and Figure 5 As shown, the outer diameter of the magnetic ring 43 is the same as the outer diameter of the ferromagnetic ring 33, the inner diameter of the sealing ring 44 is the same as the inner diameter of the ferromagnetic ring 33, and there is a gap between the magnetic ring 43 and the sealing ring 44.

[0041] Among them, the magnetic ring 43 is a ring-shaped permanent magnet structure, and the ferromagnetic ring 33 is a ring structure made of ferromagnetic material.

[0042] Furthermore, the thickness of the sealing ring 44 is greater than the thickness of the magnetic ring 43, and when the magnetic ring 43 and the ferromagnetic ring 33 are attracted, the sealing ring 44 contacts the ferromagnetic ring 33 before the magnetic ring 43.

[0043] Thus, when the magnetic ring 43 and the ferromagnetic ring 33 are attracted together, the sealing ring 44 is compressed and deformed, sealing the gap between the connecting ring 42 and the ferromagnetic ring 33.

[0044] Furthermore, the outer diameter of the insertion tube 45 is the same as the inner diameter of the raw material inlet 34. In this way, when the insertion tube 45 is inserted into the raw material inlet 34, a larger gap can be avoided, making the state of the insertion tube 45 more stable after insertion.

[0045] In an optional embodiment, a connecting flange 411 is provided on the side of the connecting pipe 41 away from the connecting ring 42, and the connecting flange 411 is connected to the quantitative conveying component 20. The connecting flange 411 can be directly connected to the conveying branch pipe 21, which is beneficial for the assembly of the connecting pipe 41.

[0046] In conjunction with the above embodiments, this utility model features a plug at the end of the raw material conveying pipeline, which is magnetically attached to the mixing container. Compared to traditional flange or threaded mechanical connections, the inserted end extends directly into the inner wall of the mixing container, avoiding dead corners at the connection point. This also facilitates uniform rinsing of the conveying pipeline and the entire plug by the cleaning fluid, improving cleaning coverage. Furthermore, since different raw materials use independent plugs, only the plug component needs to be replaced during replacement, avoiding the mixing of trace amounts of residue caused by shared interfaces.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
