[0002] In the industrial printing field, the ink-distributing structure of the ink roller is mainly used in cooperation with the printing roller, the printing roller and the ink-distributing roller always keep the ink-distributing interval set by the user, and the ink-distributing roller moves along with the printing roller, so that the ink-distributing roller keeps the printing ink on the printing roller flat. However, the ink-distributing structure in the above industrial printing is difficult to meet the demand of miniaturized desktop printing.

[0003] The desktop printing equipment mainly develops in the direction of miniaturization and simplicity. If the linkage structure is selected between the printing roller and the ink-distributing roller, the ink roller assembly will be too large, the structure and control complexity of the desktop printing equipment will be increased, and the problem of too large volume of the desktop printing equipment will be caused. Therefore, the desktop printing machine in the prior art is provided with ink-distributing components at the corner positions, and then the movement of the printing roller to the ink-distributing components is controlled to process the flatness of the ink on the printing roller.

[0004] The above structure reduces the structure and control complexity of the desktop printing equipment, but when the printing roller and the ink-distributing component are separated, the printing roller is easy to be adhered to the ink-distributing component, so that the ink-distributing effect is destroyed.

[0026] The following description and accompanying drawings fully illustrate specific embodiments of the invention to enable those skilled in the art to practice them. Other embodiments may include structural, logical, electrical, procedural, and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary. Some portions and features of some embodiments may be included in or replace portions and features of other embodiments. The scope of embodiments of the invention includes the entire scope of the claims and all available equivalents thereof. In this document, these embodiments of the invention may be referred to individually or collectively with the term "invention," which is merely for convenience and is not intended to automatically limit the scope of the application to any single invention or inventive concept if more than one invention is disclosed.

[0027] It should be noted that, where there is no conflict, the various technical features in the embodiments of the present invention can be combined with each other.

[0028] This invention provides a desktop printing ink spreading device, such as... Figure 1 As shown, Figure 1 This is a structural example of a desktop printing ink distribution device according to an embodiment of the present invention. The desktop printing ink distribution device includes: an ink roller 1, a doctor blade 2, and a moving component (not shown); wherein the ink roller 1 and the doctor blade 2 are arranged in the same direction (i.e., the axial direction of the ink roller 1 is consistent with the length direction of the doctor blade 2); the moving component is used to control the relative displacement of the ink roller 1 and / or the doctor blade 2 along the axial direction of the ink roller 1.

[0029] During ink distribution, the ink roller 1 and the doctor blade 2 maintain a set ink distribution distance. Driven by the moving parts, the two are relatively displaced along the axial direction of the ink roller 1, and gradually form ink distribution cooperation between the ink roller 1 and the doctor blade 2 through the rotation of the ink roller 1 itself.

[0030] In this configuration, the moving component can independently control the axial displacement of the ink roller 1 to achieve uniform ink distribution with the fixedly positioned doctor blade 2; alternatively, the moving component can independently control the axial displacement of the doctor blade 2 to achieve uniform ink distribution with the fixedly positioned ink roller 1; or, the moving component can control both the ink roller 1 and the doctor blade 2 separately, allowing both to move axially to achieve the aforementioned uniform ink distribution. The structure of the moving component independently or separately controlling the ink roller 1 and the doctor blade 2 can be achieved using various methods in the prior art, such as screws, chains, and slide rails, which will not be elaborated upon here.

[0031] For example, the moving parts control the ink roller 1 to move axially, forming a uniform ink engagement with the fixedly positioned doctor blade 2; during uniform ink engagement, the ink roller 1 rotates and moves closer to the doctor blade 2, first contacting one end of the doctor blade 2, and then gradually moving towards the doctor blade until the ink roller passes through the entire doctor blade 2, so that the ink on the entire surface of the ink roller 1 is uniformly treated by the doctor blade.

[0032] In some embodiments, the axial direction of the ink roller 1 and the length direction of the doctor blade 2 can be kept consistent only when ink is being evenly distributed (in ink even mode). The direction of the ink roller 1 and / or the doctor blade 2 can be adjusted by rotating the component. The adjustment purpose can be used for ink even distribution, storage, printing, etc.

[0033] In this embodiment of the invention, the scraper 2 can be configured to cooperate with the upper, lower, left, right, and any angle of the circumferential surface of the ink roller 1. For example, when uniformly distributing ink, the scraper 2 is located above the ink roller 1 to cooperate with the ink roller 1 for uniform ink distribution. Or, when uniformly distributing ink, the scraper 2 is located at an angle of 135° to the ink roller 1 to cooperate with the ink roller 1 for uniform ink distribution. Specifically, it can be arbitrarily set within a 360° range around the ink roller 1, and there is no limitation on this.

[0034] This invention modifies the traditional radial separation of the ink roller and the ink distribution component to axial separation between them, avoiding defects such as adhesion, burrs, and dents on the ink roller caused by the traditional radial separation. This ensures the smoothness of the printing ink on the ink roller and provides a reliable guarantee for the printing quality of the desktop printing ink distribution device.

[0035] The ink uniformity distance (i.e., the minimum radial distance between the ink roller 1 and the doctor blade 2) maintained by the ink roller 1 and the doctor blade 2 during the ink uniformity process in this embodiment of the invention can be a fixed value set by the designer, or an ink uniformity distance set or adjusted by the user. It can be achieved by the radial displacement (perpendicular to the above-mentioned axial direction) provided by the moving parts, or by other motion control parts.

[0036] In the process of ink distribution, ink tends to accumulate at the scraping end of conventional doctor blades. When using printing inks that are prone to oxidation, the ink accumulated at the blade end can easily form scale, thus affecting the ink distribution quality, such as the smoothness and thickness of the ink. Furthermore, conventional doctor blades require high precision. If the ink distribution spacing is not set correctly, a large amount of ink will be scraped away from the ink roller 1, resulting in significant ink loss and waste. In addition, the scraping end of conventional doctor blades has low strength and is prone to bending and deformation under strong external forces, leading to ink distribution failure.

[0037] To address the aforementioned problems, this embodiment of the invention utilizes a roller-type doctor blade 2, thereby overcoming the issues of traditional doctor blades. Firstly, the structural strength of the roller-type doctor blade 2 is far superior to that of a bladed doctor blade, making it less prone to deformation. Secondly, the arc-shaped surface of the roller-type doctor blade 2 reduces ink accumulation, creating compression rather than scraping against the ink roller 1, thus avoiding significant ink loss and waste. This also provides redundancy in setting the ink distribution spacing, allowing for normal ink distribution even when in contact with the ink roller 1 and the ink distribution spacing is 0. Furthermore, if a soft roller structure is used for the ink roller 1 and / or the roller-type doctor blade 2, the ink distribution spacing can be designed to be negative. The surface of the roller-type doctor blade 2 that forms the ink distribution contact with the ink roller 1 is an arc-shaped surface, achieving the effect of the roller-type doctor blade 2 in this application. Therefore, the area not in contact with the ink roller 1 can be of other structures.

[0038] like Figure 2 In some embodiments, the desktop printing ink distribution device further includes: a doctor blade fixing seat 4; the doctor blade fixing seat 4 is used to assemble and fix the doctor blade 2; the doctor blade 2 can be fixed on the doctor blade fixing seat 4. For the roller-type doctor blade 2, the doctor blade fixing seat 4 can be provided with an arc-shaped groove 5 corresponding to the shape of the roller-type doctor blade 2. The surface of the arc-shaped groove 5 has an opening for exposing part of the roller-type doctor blade 2. The exposed part of the roller body does not exceed 1 / 2 of the circumferential surface of the roller-type doctor blade 2, so that the roller-type doctor blade 2 is held and fixed in the arc-shaped groove 5 by the opening position of the arc-shaped groove 5, and the exposed part is used to form a gradual ink distribution cooperation with the ink roller 1.

[0039] In this embodiment, by opening an arc groove 5 on the doctor blade fixing seat 4 to fix the roller-type doctor blade 2, it is beneficial to hide the roller-type doctor blade 2 and realize the miniaturization and compactness of the ink uniform structure of the desktop printing ink uniform device.

[0040] In this embodiment, the roller-type doctor blade 2 can be fixed (non-rotatable) within the arc-shaped groove 5, or it can be a rotatable structure within the arc-shaped groove 5. When the roller-type doctor blade 2 is fixed (non-rotatable), it can form a scraping motion with the ink roller 1, which can further ensure the uniform ink thickness on the ink roller 1.

[0041] like Figure 3As shown, in some optional embodiments, an elastic element 6 can be provided between the roller-type doctor blade 2 and the doctor blade fixing seat 4 to give the roller-type doctor blade 2 a certain amount of elastic extension and contraction, so that the roller-type doctor blade 2 has a certain self-adaptive capability. The elastic element 6 can be a spring, elastic washer, etc. In this embodiment, the roller-type doctor blade 2 can have a certain amount of displacement in the arc groove 5 (the displacement direction can be perpendicular to the tangent of the contact point between the roller-type doctor blade and the ink roller, or other directions that can be separated from this perpendicular direction), so that the function of the elastic element 6 in giving the roller-type doctor blade 2 an elastic extension and contraction can be realized.

[0042] On the other hand, the elastic element 6 between the roller-type doctor blade 2 and the doctor blade fixing seat 4 can enable the roller-type doctor blade 2 to have the above-mentioned adaptive ability, so as to achieve the effect of controlling the ink uniformity.

[0043] Preferably, the roller-type scraper 2 has a flat surface at the bottom of the arc groove 5 of the scraper fixing seat 4 that abuts against the elastic member 6, and this flat surface can form a better fit with the elastic member 6; in other embodiments, the bottom of the arc groove 5 of the scraper fixing seat 4 can also be an arc surface, which can also satisfy the above-mentioned adaptive roller-type scraper 2.

[0044] In some embodiments, a slot is provided at the position opposite to the elastic member 6 of the roller scraper 2. The bottom of the slot is a planar structure, and the elastic member 6 abuts against the bottom plane of the slot. The slot is used to limit the elastic member to prevent the elastic member 6 from shifting.

[0045] In some embodiments, the bottom of the arc-shaped groove 5 of the scraper fixing seat 4 is a planar structure, which abuts against the other end of the elastic member 6. Alternatively, a slot hole opposite to the elastic member 6 is provided at the bottom of the arc-shaped groove 5 of the scraper fixing seat 4, and the bottom surface of the slot hole is a planar surface, which is used to place and limit the elastic member 6. In this embodiment, when a slot hole is provided at the position opposite to the elastic member 6 in conjunction with the roller scraper 2, the elastic member 6 can limit the roller scraper 2, which limits the displacement of the roller scraper located in the arc-shaped groove along the length direction.

[0046] like Figure 4 As shown, in some embodiments, the bottom of the scraper fixing seat 4 is a split assembly structure, including a main body 41 and a bottom plate 42; wherein, the arc groove 5 is located on the main body 41, and the slot in the arc groove 5 is a through hole structure, which supports the elastic element 6 by assembling the bottom 42. This structure facilitates the assembly of the elastic element 6.

[0047] In other embodiments, the bottom of the arc groove 5 of the scraper fixing seat 4 is a planar structure and the bottom surface of the roller scraper 2 is a planar structure. The elastic element 6 may not be provided between them, and the two resist each other to play a role in preventing rotation and fixing.

[0048] likeFigure 5 As shown, in some other embodiments, the bottom plane of the roller scraper 2 is provided with a retaining plate 7 at both ends. The retaining plate 7 can be used to cooperate with the elastic member 6 to limit the roller scraper 2. Preferably, a limiting gasket 8 is provided between the roller scraper 2 and the elastic member 6. The limiting gasket 8 is used to cooperate with the retaining plate 7 to limit the roller scraper 2. The limiting is used to restrict the displacement of the roller scraper located in the arc groove along the length direction. The limiting gasket 8 can be made of rigid material. Compared with directly using the elastic member 6 for limiting, its structure is more stable and less prone to extrusion deformation.

[0049] In this embodiment of the invention, the number of elastic elements 6 can be one or more, and the number of limiting pads 8 corresponds to the number of elastic elements 6.

[0050] Preferably, the bottom retaining platform 7 of the roller scraper 2 is formed by the round end face of the roller scraper 2, that is, the end face of the roller scraper 2 still maintains a regular round structure. For example, a groove is made in the middle of the bottom of the roller scraper 2 to form the bottom plane mentioned above, and its end face constitutes the retaining platform on both sides of the plane.

[0051] like Figure 6 As shown, in some optional embodiments, multiple doctor blades 2 are arranged side by side; during ink mixing, the ink roller 1 and any one of the doctor blades 2 form a gradual ink mixing cooperation. This embodiment is mainly to improve the ink mixing working time of the doctor blades 2. Since ink residue will remain on the doctor blades 2 during long-term ink mixing, the residual ink or the oxide of the residual ink will affect the ink mixing effect. Therefore, the doctor blades 2 need to be cleaned frequently. By setting multiple doctor blades 2 side by side in this embodiment, the ink roller 1 can select or use the doctor blades 2 in sequence, thereby improving the overall ink mixing time of the doctor blades 2.

[0052] In this embodiment of the invention, the length of the doctor blade 2 can be greater than, equal to, or less than the length of the ink roller 1. Since this application achieves gradual ink distribution through axial movement between the doctor blade 2 and the ink roller 1, the length of the doctor blade 2 can be reduced, thus saving space and facilitating the miniaturization of the desktop printing ink distribution device. On the other hand, a larger doctor blade 2 requires higher positional accuracy. This is because a slight offset at one end will gradually increase under the influence of the doctor blade 2's length, severely affecting the ink distribution effect and potentially damaging itself and the ink roller 1. Therefore, miniaturizing the doctor blade 2 reduces the requirements for assembly accuracy and also facilitates adjustment. Preferably, the length of the doctor blade 2 does not exceed 1 / 3 of the length of the ink roller 1.

[0053] In some embodiments, the length of the doctor blade 2 is not less than 1 / 10 of the length of the ink roller 1, thereby reducing the influence of both ends of the doctor blade on the ink uniformity effect.

[0054] like Figure 7-8 As shown, in some alternative embodiments, the desktop printing ink distribution device further includes: a tray 9 for mounting the doctor blade 2; and a waste liquid collection component 10 mounted under the tray 9, the waste liquid collection component 10 communicating with the drain port of the tray 9, the tray 9 and the waste liquid collection component 10 being used to contain ink squeezed out or leaked due to ink distribution.

[0055] In some embodiments, the desktop printing ink distribution device further includes: an ink roller frame 11; the ink roller 1 is fixed on the ink roller frame via a rotating shaft. In some embodiments, a heating component may also be provided on the ink roller 1, such as a heating rod added to the roller body.

[0056] The printing ink used in the desktop printing ink distribution device in this embodiment of the invention can be commercially available water-based ink, oil-based ink, conductive paste, etc. For example, a conductive paste made of metal material can be selected. This conductive paste contains at least a low-melting-point metal with a melting point below 300°C. This type of low-melting-point metal can be divided into room-temperature liquid low-melting-point metal and room-temperature solid low-melting-point metal under room temperature conditions. Room-temperature liquid low-melting-point metal refers to a low-melting-point metal with a melting point below room temperature, which can be in a liquid state at room temperature, such as gallium, gallium-indium alloy, gallium-indium-tin alloy, gallium-tin alloy, gallium-indium-tin-zinc alloy, etc., gallium-based alloys. Room-temperature solid low-melting-point metal refers to a low-melting-point metal with a melting point above room temperature but below 300°C, which is still in a solid state at room temperature, such as indium, tin, bismuth, bismuth-indium alloy, bismuth-tin alloy, bismuth-indium-tin alloy, indium-tin alloy, etc., bismuth-based alloys, indium-based alloys, tin-based alloys, etc.

[0057] In addition to low-melting-point metals, the conductive paste in this embodiment of the invention may also include high-melting-point conductive metal particles, such as micro-nano-sized silver powder, copper powder, and silver-coated copper powder. These conductive metal particles can improve the conductivity of the conductive paste. In addition, other metal / non-metal particles can be added to improve or enhance the corresponding functional properties of the conductive paste, such as gold powder, nickel powder, which can improve the oxidation resistance of the conductive paste, non-conductive fillers used to improve the viscosity of the conductive paste, and pigments, etc.

[0058] When one or more of the above-mentioned solid particles are added to the conductive paste in the embodiments of the present invention, it can be in a viscous state. In contrast to the above-mentioned solid and liquid states, the viscous state is considered to be a form of liquid state.
