Description

Technical Field

[0001] This utility model relates to the field of paint tinting technology, specifically to a uniform mixing device for water-based paint tinting tanks. Background Technology

[0002] In the coatings manufacturing industry, water-based paints are gradually becoming the mainstream choice in the market due to their advantages such as environmental friendliness and low pollution. In practical applications, in order to obtain colors and performances that meet different needs, it is often necessary to perform color matching and mixing operations on water-based paints.

[0003] Utility model patent CN221015506U discloses a low-temperature water-based paint mixing tank. This tank includes a tank body with an outlet pipe equipped with a third valve at the bottom. A drive motor is located at the bottom of the tank body, and a paint inlet pipe connected to the top of the tank body is also present. The shaft of the drive motor extends into the tank body and is connected to a stirring shaft with stirring blades. Multiple pigment filling tanks connected to the upper part of the tank body via pigment outlet pipes are located, and each pigment filling tank has a pigment filling pipe at its upper end. A first valve is located on the pigment outlet pipe, and a second valve is located on the pigment filling pipe. Multiple observation windows are located on the side of the pigment filling tank, enclosed by a transparent sheet with vertically extending scale markings. This low-temperature water-based paint mixing tank can accurately add different colors of pigment to low-temperature water-based paint according to the pigment mixing ratio, resulting in a small color error.

[0004] Traditional water-based paint mixing tanks typically employ a single stirring shaft and a simple stirring paddle structure. During operation, these devices often only produce a strong stirring effect in localized areas of the tank, easily creating dead zones and hindering the uniform mixing of the water-based paint throughout the entire tank. This results in different colors or compositions of water-based paint failing to fully blend in these areas, leading to uneven color and performance of the mixed paint and affecting the quality of the final product. Furthermore, during the feeding process, traditional devices often simply pour the water-based paint directly into the tank without effective dispersion treatment. This prevents the newly added water-based paint from quickly mixing with the existing paint, further exacerbating the problem of uneven mixing. Therefore, we propose a uniform mixing device for water-based paint mixing tanks. Utility Model Content

[0005] The purpose of this invention is to provide a uniform mixing device for water-based paint mixing tanks, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A uniform mixing device for a water-based paint tinting can includes a can body, a top cover mounted on the top of the can body, a baffle mounted on the top of the top cover, a stirring motor mounted at the center of the top of the baffle, a main stirring shaft positioned at the center of the interior of the can body, a drive gear mounted on the top of the main stirring shaft, and the top of the main stirring shaft coaxially connected to the end of the output shaft of the stirring motor. Several stirring paddles are fitted and fixed onto the main stirring shaft. Several water-based paint feeding mechanisms are also provided within the can body, arranged in a ring at equal intervals. The water-based paint feeding mechanism includes a feeding shaft parallel to the main stirring shaft, several stirring plates fixed on the outer surface of the feeding shaft, and a driven gear fixed on the top of the feeding shaft. The feeding shaft has a tubular structure. Both the top and bottom ends of the stirring plates are fixed with discharge pipes. The end of the discharge pipe is inserted into the interior of the feeding shaft and connected to the feeding shaft. Several discharge holes are opened on the outer surface of the discharge pipe. Several inlet pipes are provided above the tank. The bottom end of the inlet pipe passes through the baffle and the top cover in sequence and is inserted into the feeding shaft.

[0008] Preferably, the top surface of the cover is annularly fixed with several fixing seats, and the feed pipe vertically passes through the fixing seats and is fixedly connected to them.

[0009] Preferably, the bottom surface of the cover is provided with a cavity, and both the driving gear and the driven gear are located in the cavity, with the driven gear meshing with the driving gear.

[0010] Preferably, the bottom end of the main stirring shaft is inserted into the inner bottom wall of the tank, and the stirring paddle includes a fixed sleeve sleeved and fixed to the outside of the main stirring shaft and a plurality of stirring rods fixed at equal intervals on the outer circumferential surface of the fixed sleeve. Several turbulence plates are fixed on the stirring paddle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The uniform mixing device of this water-based paint mixing tank, by distributing multiple water-based paint feeding mechanisms in a ring, with the feed pipe connected to the feed shaft, and the feed shaft dispersing the water-based paint ingredients into the tank from different positions through the discharge pipe and discharge hole, compared with the traditional single feed pouring, this method allows the water-based paint ingredients to be evenly distributed from the beginning, laying the foundation for efficient mixing.

[0017] 2. The uniform mixing device of this water-based paint tinting tank enables the feeding mechanism to perform both feeding and mixing functions. When the main mixing shaft rotates, it drives the driven gear to rotate through the driving gear, thereby causing multiple feeding shafts to drive the mixing plates to mix synchronously. Horizontally, the mixing plates and mixing paddles work together to expand the mixing range and reduce the mixing dead angles at the edges and corners of the tank. Vertically, the mixing paddles and mixing plates are staggered to form convection, reducing unevenness caused by height differences and improving the uniformity and quality of mixing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7 This utility model provides a technical solution:

[0031] A uniform mixing device for a water-based paint tinting can includes a tank body 1. A top cover 11 is mounted on the top of the tank body 1, and a baffle 12 is mounted on the top of the top cover 11. A stirring motor 121 is mounted at the center of the top of the baffle 12. A main stirring shaft 2 is located at the center of the interior of the tank body 1. The top of the main stirring shaft 2 is coaxially connected to the end of the output shaft of the stirring motor 121. When the stirring motor 121 is started, it drives the main stirring shaft 2 to rotate. The bottom end of the main stirring shaft 2 is inserted into the inner bottom wall of the tank body 1, thus confining the bottom end of the main stirring shaft 2 within the tank body 1 and preventing it from wobbling during rotation.

[0032] In this invention, a plurality of stirring paddles 21 are sleeved and fixed on the main stirring shaft 2. When the main stirring shaft 2 rotates, it can drive the stirring paddles 21 to rotate together. Each stirring paddle 21 includes a fixed sleeve 211 sleeved and fixed to the outside of the main stirring shaft 2, and a plurality of stirring rods 212 annularly and equally spaced fixed to the outer circumferential surface of the fixed sleeve 211. Several flow-disrupting plates 213 are fixed on the stirring paddle 21. The fixed sleeve 211 is tightly connected to the main stirring shaft 2 with fastening bolts to prevent loosening during stirring. The stirring rods 212 can generate shear force on the water-based paint during rotation, achieving the purpose of stirring. Several flow-disrupting plates 213 are fixed on the stirring paddle 21, and the plates 213 are distributed in an inclined manner. When the main stirring shaft 2 drives the stirring paddle 21 to rotate, the flow-disrupting plates 213 can cause the water-based paint to flow irregularly, breaking the laminar flow state, promoting the full mixing of water-based paint in different areas, and improving the mixing effect.

[0033] Specifically, several feed pipes 123 are provided above the tank body 1. The bottom end of the feed pipe 123 passes through the baffle 12 and the top cover 11 in sequence and extends into the tank body 1. Several fixing seats 122 are fixed in a ring shape on the top surface of the baffle 12. The feed pipe 123 vertically passes through the fixing seats 122 and is fixedly connected to the fixing seats 122. During the feeding process, water-based paint raw materials of different components enter the tank body 1 in an orderly manner through the feed pipes 123. At this time, the main stirring shaft 2 drives the stirring paddle 21 to rotate continuously, so that the newly entered water-based paint is quickly mixed with the original water-based paint in the tank, realizing a highly efficient working mode of feeding and mixing simultaneously.

[0034] Furthermore, the tank body 1 is also equipped with several water-based paint feeding mechanisms 3, which are arranged in a ring at equal intervals within the tank body 1. Each water-based paint feeding mechanism 3 includes a feeding shaft 31 parallel to the main stirring shaft 2, several stirring plates 32 fixed to the outer surface of the feeding shaft 31, and a driven gear 33 fixed to the top of the feeding shaft 31. The bottom surface of the cover 12 is provided with a cavity, and the top of the main stirring shaft 2 is provided with a driving gear 22. Both the driving gear 22 and the driven gear 33 are located within this cavity, and the driven gear 33 meshes with the driving gear 22. When the stirring motor 121 drives the main stirring shaft 2 to rotate, the driving gear 22 rotates accordingly, driving the driven gear 33 to rotate through gear meshing, thereby causing the feeding shaft 31 to rotate synchronously and driving the stirring plates 32 to stir the water-based paint, achieving the purpose of mixing the raw materials. An inclined plate 322 is also fixed on the outer surface of the stirring plate 32. The inclined plate 322 is inclined so that when the stirring plate 32 is stirring, the liquid that comes into contact with the inclined plate 322 can move along the inclined plate 322, so that the inclined plate 322 can play a role in turbulence and increase the mixing effect.

[0035] Furthermore, the feeding shaft 31 has a tubular structure, and the bottom end of the feed pipe 123 is inserted into the feeding shaft 31, allowing the water-based paint to flow smoothly from the feed pipe 123 into the feeding shaft 31. Both the top and bottom ends of the stirring plate 32 are fixed with discharge pipes 321, the ends of which are inserted into the interior of the feeding shaft 31 and connected to it. Several discharge holes 3211 are provided on the outer surface of the discharge pipe 321. When the feeding shaft 31 rotates, the water-based paint raw material entering the feeding shaft 31 is dispersed into the tank 1 through the discharge holes 3211 as the raw material is continuously injected. This dispersion method allows the water-based paint to come into more extensive contact with the existing paint liquid in the tank, accelerating the mixing process.

[0036] Furthermore, the bottom end of the feeding shaft 31 is inserted into the bottom wall inside the tank 1, thus confining the bottom end of the feeding shaft 31 within the tank 1 and preventing the feeding shaft 31 from wobbling during rotation. A plunger 311 is fitted onto the bottom of the feeding shaft 31, which seals the bottom end of the feeding shaft 31. The plunger 311 prevents water-based paint from leaking from the bottom of the feeding shaft 31, ensuring that the water-based paint can only flow out through the discharge hole 3211 on the discharge pipe 321. This ensures that the water-based paint is dispersed into the tank 1 along a predetermined path, improving the accuracy and stability of the feeding process.

[0037] It is worth noting that the external dimensions of the feed pipe 123 are compatible with the internal dimensions of the feed shaft 31. The feed shaft 31 can rotate coaxially on the outside of the discharge pipe 321. This compatibility ensures the sealing between the feed pipe 123 and the feed shaft 31, preventing water-based paint from leaking at the connection, while also allowing the feed shaft 31 to rotate freely, so that the water-based paint is not obstructed during the conveying process. At the same time, the stirring plate 32 can rotate with the feed shaft 31 to stir the water-based paint in the tank.

[0038] It should be added that the distance between the main stirring shaft 2 and the feeding shaft 31 is L. The maximum radius of the profile of the stirring paddle 21 when rotating and the maximum radius of the profile of the stirring plate 32 when rotating are both less than L, and the stirring paddle 21 and the stirring plate 32 are staggered in the vertical direction. This design avoids the stirring paddle 21 and the stirring plate 32 from colliding with each other during rotation, ensuring the safe and stable operation of the stirring equipment. During the stirring process, the stirring paddle 21 and the stirring plate 32 cooperate with each other to form complex water flow and vortex, so that the water-based paint can flow and mix fully in both the vertical and horizontal directions. At the same time, they each stir in different areas, expanding the stirring range and allowing the water-based paint to be fully mixed in a larger space.

[0039] It is worth noting that the stirring motor 121 involved in this utility model is a conventional technology and will not be described in detail here.

[0040] In this embodiment, the uniform mixing device for the water-based paint tinting tank first injects various raw materials through the respective inlet pipes 123, allowing the raw materials to be injected into the tubular feeding shaft 31. As the raw materials are injected, they are dispersed into the tank body 1 through the outlet hole 3211. Then, the stirring motor 121 is started to drive the main stirring shaft 2 to rotate, which in turn drives the stirring paddle 21 to rotate. At this time, the stirring rod 212 in the stirring paddle 21 generates a shearing force on the water-based paint mixed in the tank, while the baffle 213 on it causes the water-based paint to flow irregularly, promoting mixing. Finally, the drive gear 22 at the top of the main stirring shaft 2 drives the feeding shaft through meshing with the driven gear 33. Rotation of shaft 31 causes the stirring plate 32, fixed on the outer surface of the feeding shaft 31, to stir the water-based paint. This allows the water-based paint feeding mechanism 3 to stir various raw materials while dispersing and injecting them, enabling the water-based paint to come into wider contact with the existing paint liquid in the tank, thus accelerating the mixing process. In addition, the distance between the main stirring shaft 2 and the feeding shaft 31 is L. The maximum radius of the profile of the stirring paddle 21 and the stirring plate 32 when they rotate is less than L. This spacing design avoids collisions between the stirring paddle 21 and the stirring plate 32 during rotation, while allowing them to cooperate to form complex water flow and vortex, expanding the stirring range and ensuring that the water-based paint is fully mixed.
