For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] As shown in the figure, a stirring and spill prevention device for UV paint includes core structures such as a base 1, a stirring tank 2, and a stirring assembly 3. The base 1 is a rectangular frame structure, preferably made of stainless steel or aluminum alloy, providing good load-bearing capacity and corrosion resistance. The base surface is treated with powder coating or solvent-resistant coating to improve its resistance to UV paint solvents. An electrical control unit 13 is installed on the base 1. The electrical control unit 13 includes a control panel with a start button, an emergency stop button, a lifting button, and a motor speed adjustment knob, facilitating operator adjustment of the equipment's operating status. The electrical control unit 13 can also be a touchscreen control panel with the aforementioned buttons. The control system can preset the stirring time and speed curve to achieve automated control. The emergency stop button is used to quickly cut off the power to the motor and push rod in emergencies, ensuring operator safety.

[0023] The mixing tank 2 has a cylindrical structure and is preferably made of polypropylene (PP) or stainless steel. A suitable corrosion-resistant material can be selected depending on the solvent used. The bottom of the mixing tank 2 is equipped with a discharge port 14 and a sealing cap 15 for easy discharge and cleaning of the UV paint after mixing. The top of the mixing tank 2 features an integrated anti-overflow structure 21, which is an annular, inwardly inclined guide surface. It is made of the same material as the tank body through integral molding or welding, with an inclination angle of 30° to 60°. This effectively guides splashed liquid back into the tank, preventing spillage and contamination.

[0024] Furthermore, the stirring assembly 3 is positioned above the base 1 and includes a support rod 4, a connecting rod 6, a fixing rod 7, a stirring head 8, and a motor 5. The support rod 4 is a vertically installed square or round tube structure, preferably made of aluminum alloy or carbon steel with a sprayed finish to ensure high stability. The electric push rod 9 is installed inside or on the side of the support rod 4, preferably using a linear electric cylinder, with a lifting stroke generally of 100–300 mm. It is controlled by the electronic control unit 13 to achieve smooth lifting and lowering of the connecting rod 6 along the direction of the support rod 4. The connecting rod 6 is a horizontally positioned long rod, made of solid stainless steel or lightweight aluminum alloy. The electric push rod 9 drives the connecting rod 6 to move vertically, thereby driving the fixing rod 7 and its associated components to lift and lower synchronously.

[0025] Furthermore, the fixing rod 7 is vertically connected to the end of the connecting rod 6 away from the support rod 4, located directly above the opening of the mixing tank 2, and is used to support the motor 5 and the mixing head 8. The fixing rod 7 has a hollow structure, housing a drive shaft and wires to ensure the sealing of the transmission and dust and splash prevention. The motor 5 is preferably a DC geared motor or a servo motor, installed at the top of the fixing rod 7. Its output shaft drives the mixing head 8 to rotate through the drive shaft, ensuring that the mixing head operates at a stable speed. The mixing head 8 can be a spiral, blade, or multi-blade structure, selected according to the viscosity and properties of the UV paint. The material is made of polytetrafluoroethylene-coated stainless steel or all stainless steel, achieving rapid and uniform mixing of the paint, effectively avoiding sedimentation and bubble formation, and improving mixing efficiency.

[0026] Furthermore, to prevent liquid splashing during stirring, a removable splash guard 10 is fitted onto the fixing rod 7. The splash guard 10 has a conical structure, made of transparent polycarbonate (PC) material or solvent-resistant resin, combining good transparency and impact resistance, facilitating observation of the stirring process and making cleaning easy. The splash guard 10 slides along the fixing rod 7 via guide grooves, guide ribs, or recesses, engaging with guide ribs or recesses on the outer wall of the fixing rod 7 to ensure smooth lifting and lowering. The inner wall of the splash guard 10 has guide holes, snap-fit, or guide groove structures, and is equipped with a knob or nut 16 for locking its height. The locking mechanism uses PA66 reinforced nylon or brass material to ensure precise adjustment and prevent loosening. The angle of the splash guard 10 matches the overflow prevention structure 21 at the top of the mixing tank 2. When closed, the inner side fits tightly against the overflow prevention structure 21, forming a ring-shaped shield, effectively preventing paint from splashing to the outside. The splash guard 10 has an inwardly bent receiving groove 11 at its bottom end to collect paint adhering to the bottom surface of the cover, preventing liquid from dripping and contaminating the equipment table when the splash guard is lifted. This splash guard structure can be manufactured using one-piece injection molding or hot-pressing bending processes, facilitating cleaning and maintenance. During operation, the operator installs the mixing tank 2 on the base 1, pours in the UV paint raw material to be mixed, and adjusts the splash guard 10 to a position where it fits tightly against the anti-overflow structure 21 at the top of the mixing tank, ensuring that liquid does not splash out during mixing. The electrical control unit 13 is activated, controlling the electric push rod 9 to descend, allowing the mixing head 8 to enter the tank. The motor 5 starts, driving the mixing head 8 to rotate, completing the uniform mixing of the paint. After mixing, the motor and electric push rod are turned off, the mixing head 8 is lifted, and the splash guard 10 is removed for cleaning. The mixed UV paint can be discharged or cleaned by opening the discharge port 14 at the bottom of the mixing tank 2 and controlling it with the sealing cap 15. When the splash guard 10 needs to be removed, simply remove the stirring head 8 first, then loosen the knob or nut 16 to release its locking state, and then slide the splash guard down along the fixing rod 7 to the bottom of the fixing rod 7 to remove it as a whole. This splash guard structure can be manufactured using one-piece injection molding or hot-pressing bending processes, facilitating cleaning and maintenance. This device has a compact structure and is easy to operate, significantly solving the problem of liquid overflow and splashing during UV paint stirring, improving safety and efficiency, and is widely applicable to the needs of furniture coating, UV-curing coatings, precision coatings, and other production fields.
