Embodiments of the invention may be referred to herein, individually or collectively, by the term "invention" merely for convenience and without intending to voluntarily limit the scope of this application to any single invention or inventive concept if more than one is in fact disclosed.
It should be noted that the technical features in the embodiments of the present invention may be combined with each other without conflict.
The embodiment of the invention discloses an ink homogenizing structure, and as shown in fig. 2, fig. 2 is a schematic structural diagram of the ink homogenizing structure in the embodiment of the invention; this ink distributing structure includes: the ink-jet printing device comprises a first roller 1 and a second roller 2, wherein the first roller 1 and the second roller 2 are in circumferential fit, and a gap 4 capable of retaining ink 3 is formed between the first roller 1 and the second roller 2; the flow guide structures 5 distributed along the axial direction are arranged in the crack 4, the flow guide structures 5 are in contact with the printing ink 3 at the crack 4, the contact position of the flow guide structures can be line contact or surface contact, so that the printing ink 3 generates a wetting effect on the flow guide structures 5, and the wetting effect generates a pulling force which enables the printing ink 3 to be uniformly distributed along the axial direction of the flow guide structures 5, so that the surface tension of the printing ink 3 is offset.
The circumferential matching relationship of the first roller 1 and the second roller 2 in the embodiment of the invention can mean that the first roller 1 and the second roller 2 are in circumferential contact, the rotation of one roller realizes the linkage relationship of the other roller, and the roller set structure of the first roller 1 and the second roller 2 is suitable for realizing the processes of inking, ink transferring, ink distributing and ink mixing on printing equipment; in another embodiment, the first roller 1 and the second roller 2 are in a non-contact structure, the first roller 1 is in a rotating structure, the second roller 2 is in a fixed structure, and a gap allowing ink with a specified thickness to pass through is reserved between the first roller 1 and the second roller 2, and the second roller 2 has a similar function to a scraper in the aspect of the first roller 1, but the gap is easier to adjust and the ink can pass through compared with the scraper.
The nip 4 in the above embodiment refers to a nip 4 in which the first roller 1 and the second roller 2 can retain the ink 3 in two nips formed by the first roller and the second roller being adjacent to each other, and the nip 4 has an upward or upward inclined angle and can retain the ink 3. In some embodiments, for some inks with certain viscosity, the first roller 1 and the second roller 2 are vertically arranged up and down to achieve the effect of retaining the ink 3, and the flow guiding structure 5 in the embodiment of the present invention can also be arranged in the gap 4.
In some embodiments, the flow guide structure 5 may be mounted in the nip 4 without being in direct contact with the first roller 1 and the second roller 2, and may be adapted to be used in a structure requiring a rotational fit between the first roller 1 and the second roller 2. In other embodiments, the flow guiding structure 5 may also be fixed on the second roller 2 and disposed in the nip 4, so that the flow guiding structure 5 is suitable for a structure using the second roller 2 as an arc scraper, and since the second roller 2 is not linked with the first roller 1, the normal operation between the first roller 1 and the second roller 2 is not affected by the flow guiding structure 5.
In the embodiment that the diversion structure 5 is arranged in the gap 4, certain gaps are respectively reserved between the diversion structure 5 and the first roller 1 and between the diversion structure 5 and the second roller 2, so that the rotation and linkage of the first roller 1 and the second roller 2 cannot be influenced by the arrangement of the diversion structure 5; meanwhile, the diversion structure 5 has the advantages that on the premise that the rotation and linkage of the first roller 1 and the second roller 2 are not influenced, the smaller the gap between the diversion structure and the first roller 1 and the gap between the diversion structure and the second roller 2 are, the better the gap is, a small amount of/trace ink can be accumulated in the axial pulling and uniform distribution, and the ink distributing reliability is further improved.
The above embodiment is suitable for most of the inks on the market, but for the low melting point metal ink, the low melting point metal is exposed in the air and is easy to be oxidized with oxygen molecules in the air, so as to form oxides on the surface of the low melting point metal, especially on the position where the first roller 1 and the second roller 2 are contacted, at this time, if the gap between the flow guiding structure 5 and the first roller 1 or the second roller 2 is too small and too close, the oxides are easy to be attached to the flow guiding structure 5, the action effect of the flow guiding structure 5 is affected, even the size of the flow guiding structure 5 is changed due to too much oxides, the rotation of the first roller 1 and the second roller 2 is affected, and the overall printing quality is affected. Therefore, for the low melting point metal ink, the gap between the flow guiding structure 5 and the first roller 1 and the second roller 2 should be not less than 2mm, so that the low melting point metal oxide is not easy to attach to the flow guiding structure 5. Preferably, the minimum gap of the flow guiding structure 5 with the first roller 1 and the second roller 2 is set to 2 mm.
The flow guide structure 5 in the embodiment of the invention can adopt a linear structure, a sheet structure or a wedge-shaped structure; the linear flow guide structure 5 may be made of an inelastic material or a material with poor elasticity, and when the linear flow guide structure 5 is disposed in the nip 4, the linear flow guide structure is in a tense state, so as to avoid the problem of reduced ink uniformity reliability caused by deformation. Preferably, the linear flow guide structure 5 can be a copper wire with the diameter of 0.1 mm-1 mm, has certain structural strength, has no elastic deformation capacity, can be kept in a tensioned state, has an obvious infiltration effect on copper and low-melting-point metal, and can achieve a good axial pulling effect on the low-melting-point metal. For the sheet-like flow guiding structure 5, a copper sheet with a thickness of 1-2mm can be used. The wedge-shaped flow guiding structure 5 may be made of copper as shown in fig. 4, or the end of the flow guiding structure 5 extending into the gap 4 may be made of metal, such as copper.
Preferably, the flow guiding structure 5 in the embodiment of the present invention is a wedge-shaped structure, and compared with the linear and sheet-shaped structures, the wedge-shaped flow guiding structure 5 has high overall structural strength and is not easy to deform, and the end portion of the wedge-shaped flow guiding structure extending into the gap 4 can be processed to be fine in linear or sheet shape. Moreover, the profile of the wedge-shaped flow guide structure 5 corresponds to the arc surface of the crack 4, so that the arrangement of the flow guide structure 5 in the crack 4 is more convenient.
In some embodiments, as shown in fig. 3, the flow guiding structure 5 may also be an arc-shaped structure corresponding to the shape of the first roller 1, and compared with a linear, sheet-shaped and wedge-shaped structure, the flow guiding structure 5 with the arc-shaped structure increases the infiltration range of the ink retained at the gap 4 on the flow guiding structure 5, and shares the amount of the ink in the gap 4, thereby achieving the effect of controlling the amount of the ink retained at the gap 4, and avoiding the problem that the ink overflows due to too much ink at the gap 4; meanwhile, the shearing force (circumferential direction) which is generated by the rotation of the first roller 1 and points to the crack 4 is matched, a space for containing part of the ink is formed between the flow guide structure 5 and the first roller 1, the flow guide structure 5 plays a role of a guard plate, the further contact between the ink and the air is reduced, and the formation of oxides is reduced to a certain extent. Furthermore, when the first roller 1 rotates at a high speed, the diversion structure 5 also has the effect of separating from the first roller 1, so that the ink is limited on the surface of the first roller 1, and the problem of reduced ink thickness on the roller during high-speed printing is avoided.
The flow guide structure 5 in the embodiment of the invention is an adjustable structure capable of moving along a linear direction, for example, the adjustable structure is realized by a telescopic bracket, a slide rail, a slide block, a screw rod and the like, so that the length of the flow guide structure 5 extending into the crack 4 can be adjusted, and the adjustable flow guide structure is suitable for different ink accumulation amounts and ink homogenization of different inks.

Wherein, water conservancy diversion structure 5 optional lamellar structure, water conservancy diversion fixing base 6 are the wedge structure, set up the assembly groove 7 corresponding with 5 shapes of water conservancy diversion structure on the water conservancy diversion fixing base 6, assembly groove 7 can satisfy and hold partial water conservancy diversion structure 5 to make the water conservancy diversion structure 5 that is located 6 tip exposures of wedge structure can stretch into crack 4. The assembly groove 7 allows the flow guide structure 5 to move linearly therein; the diversion fixing seat 6 is further provided with a threaded hole 8 communicated with the assembling groove 7, and the threaded hole 8 is used for clamping and fastening the diversion structure 5 through a bolt 9.
The diversion fixing seat 6 with the wedge-shaped structure in the embodiment of the invention has the structural advantage of convenient placement and installation, and simultaneously can strengthen the overall strength of the sheet diversion structure 5 and prevent the sheet diversion structure from bending and deforming. Meanwhile, the extension and contraction of the flow guide structure 5 on the flow guide structure can be realized, so that the length of the flow guide structure 5 extending into the crack 4 can be adjusted, and the flow guide structure is suitable for different ink accumulation amounts and different ink homogenization.
In some embodiments, the flow guide structure 5 penetrates through the assembly groove 7 of the flow guide fixing seat 6, and a scale 10 indicating the length of the flow guide structure 5 extending into the crack 4 is arranged at one end of the flow guide structure 5 away from the crack 4, so as to facilitate the accurate control requirement of an operator. Specifically, the scale 10 can be used to directly indicate the length of the flow guiding structure 5 extending from the flow guiding fixing seat 6.
