[0002] UV ink processing equipment is a key piece of equipment in printing, coating, and other fields. The performance of its core component, the agitator, directly affects the uniformity and curing effect of the ink. Traditional UV ink agitators mostly use straight paddle or spiral agitator structures, which have the following drawbacks: 1) Low agitation efficiency: Traditional structures lack sufficient shear force for high-viscosity UV inks, easily leading to pigment sedimentation or uneven dispersion, affecting printing quality; 2) Difficult disassembly and maintenance: Agitator components are mostly fixed with bolts, requiring special tools for disassembly, and replacement or cleaning is time-consuming and labor-intensive, affecting production efficiency. Therefore, there is an urgent need for a UV ink agitator with high agitation efficiency and easy disassembly to meet the needs of efficient production and maintenance. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0027] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Reference Figure 1-4 As shown, a UV ink processing device includes a support frame 10.

[0029] A stirring device 20 is used to stir UV ink. A cover plate 200 is provided at the end of the stirring device 20, and a discharge port 202 is provided on the stirring device 20. The stirring device 20 has a U-shaped stirring structure inside. The U-shaped stirring structure includes a first shaft 70 and a U-shaped frame 700 fixed to the outer wall of the first shaft 70. A reinforcing inclined rod 702 is provided between the first shaft 70 and the U-shaped frame 700. A stirring component is provided on the U-shaped frame 700. The stirring component includes a connecting plate 704, a hinge 706 provided on the connecting plate 704, and a screw 708 for connecting the stirring component and the hinge 706.

[0030] Specifically, the U-shaped stirring structure is connected to the drive device through the first shaft 70, and the U-shaped frame 700 is fixed to the outer wall of the shaft to form a stable stirring frame. The reinforcing diagonal bar 702 is welded between the first shaft 70 and the U-shaped frame 700 to enhance the overall rigidity and prevent deformation during high-speed stirring. The arc design of the U-shaped frame can guide the ink to form a circulating flow and avoid local deposition.

[0031] Specifically, the inner surface of the U-shaped frame 700 is coated with a wear-resistant ceramic coating, and the ratio of the opening width of the U-shaped frame 700 to the inner diameter of the stirring device 20 is 1:1.2-1.5. By covering the inner surface of the U-shaped frame 700 with a wear-resistant coating, the corrosion and wear of the ink on the metal can be reduced. Furthermore, the optimized ratio of the opening width of the U-shaped frame to the inner diameter of the stirring device ensures fluidity during stirring while avoiding insufficient shear force due to excessive space. This design is particularly suitable for the uniform dispersion of high-viscosity UV inks.

[0032] Furthermore, the stirring component is fixed to the U-shaped frame 700 by hinges 706 and screws 708, forming a movable connection. When the stirring device is running, the stirring component (connecting plate 704) automatically adjusts its angle under the ink resistance, enhancing the shearing and mixing effect on the ink. This dynamic adjustment function can adapt to inks of different viscosities and improve stirring efficiency.

[0033] Specifically, the top of the cover plate 200 has a slot 60 that communicates with the stirring device 20. A first rotating plate 600 and a second rotating plate 602 are rotatably arranged on the left and right sides of the slot 60. A slot 604 is respectively provided at one end of the first rotating plate 600 and the second rotating plate 602, so as to fix the adapter 506.

[0034] A quick-release structure is used to connect the first shaft 70 and the second shaft 80 driven by the motor 40. The quick-release structure includes an elastic locking assembly at the end of the first shaft 70, thereby enabling quick assembly and disassembly of the first shaft 70 and the second shaft 80. The elastic locking assembly includes a mounting rod 712, a groove 7120 surrounding the outer wall of the mounting rod 712, a hollow post 7122 inside the groove 7120, a spring 7124 inside the hollow post 7122, and an elastic buckle 7126 connected to the spring 7124. The end of the elastic buckle 7126 is provided with a conical locking cap 7128, and the end of the second shaft 80 is provided with a locking hole (not shown in the figure) that matches the elastic buckle 7126.

[0035] A cleaning structure 50, located at the top of the stirring device 20, is used to clean the interior of the stirring device 20. The cleaning structure 50 includes a cavity 500, a water outlet 502 surrounding the outer periphery of the cavity 500, a connecting portion 504 at one end of the cavity 500, an adapter 506 threadedly connected to the connecting portion 504, and an outer connecting pipe 508 at one end of the adapter 506. The water outlet 502 is inclined, with its axis forming an angle of 30-45° with the vertical direction. During cleaning, the cleaning fluid is sprayed from the surrounding water outlet 502, forming a multi-angle jet stream that covers the inner wall of the stirring device and the U-shaped structure. The inclined design of the water outlet creates a swirling effect in the cleaning fluid, effectively removing residual ink.

[0036] The rotating device 30 is connected to the stirring device 20 and is used to drive the stirring device 20 to flip over to pour out the ink.

[0037] Working principle: Motor 40 drives the U-shaped stirring structure connected by the quick-release structure to rotate via the second shaft 80. The first shaft 70 drives the U-shaped frame 700 to move circumferentially within the stirring device 20. The wear-resistant ceramic coating on the inner surface of the U-shaped frame has an opening width ratio of 1:1.2-1.5 with the inner diameter of the stirring device. Combined with the rigid structure with reinforcing inclined bar 702, it achieves efficient shearing and stirring of high-viscosity UV ink. The stirring component hinged to the U-shaped frame is fixed by the connecting plate 704, which is fixed by hinge 706 and screw 708. Under the action of centrifugal force, the angle is adaptively adjusted to enhance the turbulent flow effect of the ink. When disassembly is required, loosening the threaded conical locking cap 7128 releases the locking force on the elastic buckle 7126. The spring 7124 pushes the elastic buckle 7126 from the second shaft. The rod 80 is withdrawn from the locking hole, at which point the first shaft 70 can be separated from the second shaft 80. During installation, the operation is reversed. First, the mounting rod 712 is inserted into the second shaft 80, the elastic buckle 7126 is squeezed and connected to the locking hole. Then, the conical locking cap 7128 is tightened to achieve axial fixation. During cleaning, the outer pipe 508 inputs cleaning agent into the cavity 500 through the threaded adapter 506. The cleaning agent forms a rotating jet stream through the water outlet 502, which is set at a 30-45° angle. With the adapter locked by the rotatable clamping plates 600 and 602 on both sides of the top slot 60 of the cover plate 200, cleaning without dead angles is achieved. After stirring, the rotating device 30 drives the stirring device to rotate as a whole, and the ink is discharged through the discharge port 202 with a filter screen.

[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.
