Description

Technical Field

[0001] This utility model relates to an ink stirrer. Background Technology

[0002] Existing ink agitators typically use agitator blades for mixing. However, traditional agitator blades are usually designed with a hollowed-out center to reduce material usage or lower mixing resistance. This design has significant technical drawbacks: the hollowed-out center reduces ink flow resistance during mixing, resulting in poor mixing performance, difficulty in achieving thorough and uniform ink mixing, low mixing efficiency, and slow ink heating, thus impacting production efficiency. Therefore, there is an urgent need for an improved ink agitator structure that can enhance mixing efficiency, improve ink mixing uniformity, and facilitate disassembly and maintenance to meet actual production needs. Utility Model Content

[0003] This invention provides an ink stirrer that can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] An ink stirrer, comprising

[0006] The mixer body;

[0007] Offset, inclined stirring blades are arranged around one end of the stirrer body;

[0008] A connector is fixed to the hollow part of the stirring blade;

[0009] The auxiliary mechanism includes an orifice plate and a connector. The orifice plate is inclinedly disposed at the hollow part of the stirring blade and has oblique holes. The connector is disposed on both sides of the orifice plate and is detachably connected to the connector.

[0010] The beneficial effects of this utility model are:

[0011] (1) When the ink agitator drives the staggered inclined agitator blade to rotate through the agitator body, the inclined perforated plate and its inclined holes set in the hollow part of the agitator blade can divide the ink into multiple fine streams and form an up-and-down wave-like flow. At the same time, the flexible snap-fit ​​structure of the plug-in component enables the quick disassembly and assembly of the perforated plate, which not only significantly improves the agitation effect and heating efficiency of the ink, but also adapts to the production of inks with different viscosity ranges. Furthermore, the modular design simplifies the maintenance process and effectively solves the problems of uneven mixing, high energy consumption and inconvenient maintenance of traditional agitators.

[0023] Reference Figure 1-5 As shown, an ink stirrer includes...

[0024] Mixer body 10;

[0025] The staggered and inclined stirring blades 20 are arranged around one end of the stirrer body 10;

[0026] Connector 30 is fixed to the hollow part of stirring blade 20;

[0027] The auxiliary mechanism 40 includes a perforated plate 400 and a connector 404. The perforated plate 400 is inclinedly disposed at the hollowed-out part of the stirring blade 20, and the perforated plate 400 has an oblique hole 402. The connector 404 is disposed on both sides of the perforated plate 400 and is detachably connected to the connector 30. The connector 404 includes: a pivot seat 4040 symmetrically disposed; a shaft 4042 passing through the pivot seat 4040; a retaining plate 4044 rotatably disposed on the connector 404 via the shaft 4042; a fastening part 4048 disposed at one end of the retaining plate 4044; an elastic member 4046 is provided on the back of the retaining plate 4044, and the elastic member 4046 is connected to the connector 404; limiting members 4050 are provided on both sides of the top of the connector 404, and one end of the limiting member 4050 extends to form a limiting part 4052.

[0028] The plug 404 is inserted into the connector 30 from bottom to top, the retaining plate 4044 is snapped into the buckle hole of the connector 30 by the elastic force of the elastic member 4046, and the limiting member 4050 abuts against the edge of the open end of the connector 30.

[0029] Specifically, the orifice plate 400 is detachably inserted from bottom to top by a plug-in fixing method, which facilitates the replacement and cleaning of the orifice plate 400, and is locked with at least one screw; the bottom-to-top tilting insertion method, combined with the centrifugal force generated by the counterclockwise rotation of the agitator body 10 on the orifice plate 400, can better prevent the orifice plate 400 from falling off, reduce the burden on the screws, and extend the service life of the equipment.

[0030] The direction of the inclined hole 402 is opposite to the inclination direction of the orifice plate 400.

[0031] Specifically, the axis of the inclined hole 402 forms an angle of 110°-130° (preferably 120°) with the normal to the plane of the orifice plate 400. When the orifice plate 400 is tilted by 30°, the actual outflow direction of the inclined hole 402 is at an angle of 45°-60° with the horizontal plane, thus forming a "scissor-like" bidirectional shear flow: the axial flow generated by the tilt of the orifice plate 400 and the radial flow generated by the inclined hole 402 interfere with each other, causing the ink to generate high-frequency vortices (frequency up to 50-100Hz), increasing the turbulent kinetic energy by 2.3 times and improving the viscosity reduction efficiency by 68%.

[0032] Furthermore, the reverse oblique hole 402 forms a "zigzag" heat conduction path, increasing the heat-receiving area per unit volume of ink by 40%. Moreover, the asymmetric jet generated by the oblique hole 402 can automatically clean the hole wall.

[0033] The tilt angle of the perforated plate 400 is 15°~60°. The perforated plate adopts a 304 stainless steel corrugated plate structure, which maintains high rigidity even when tilted, with a maximum deformation of <0.1mm (under a 50000cP ink load).

[0034] Furthermore, this case also includes the following chart regarding the compatibility of the perforated plate at a 400° tilt angle with the ink:

[0035]

[0036] As shown in the chart above, by limiting the tilt angle of the perforated plate 400 to 15°-60°, the same stirrer can be adapted to an ink viscosity range of 500-50,000 cP. Specifically, at a tilt angle of 30°-45°, the fineness of offset ink is controlled at 5.1 μm (compared to 15 μm in Comparative Document 1), and temperature uniformity is improved by 68%. This angle range has been experimentally verified as the optimal solution; exceeding this range will lead to a significant decrease in shear efficiency or flowability.

[0037] Working principle: When the agitator body 10 drives the staggered inclined agitator blade 20 to rotate, the inclined perforated plate 400 set in the hollow part of the agitator blade 20 divides the ink into multiple fine streams through the inclined holes 402. The design of the inclined holes 402 being opposite to the inclination direction of the perforated plate 400 causes the ink to form an up-and-down wave-like flow during the agitation process. At the same time, through the elastic snap-fit ​​structure of the plug-in member 404, including the pivot seat 4040, the shaft 4042, the snap-fit ​​plate 4044 with the fastening part 4048, and the elastic member 4046, the perforated plate 400 can be quickly and detachably fixed on the connector 30, and the limiting member 4050 ensures the stability of the installation. This structure not only enhances the "stringing" agitation effect of the ink, but also realizes convenient maintenance of the agitator assembly.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
