Description

Technical Field

[0001] This utility model relates to the field of paint production technology, specifically to a low-speed dispersion device for paint production. Background Technology

[0002] In the paint and coating production process, the core function of the dispersion unit is to fully disperse and evenly distribute the pigments and fillers in the paint and coating throughout the matrix. This not only helps improve the hiding power and coloring effect of the coating but also enhances its stability and weather resistance. By optimizing the dispersion process, optimal pigment development and uniform filler distribution can be achieved, thereby improving the overall performance of the coating. An effective dispersion process is crucial for ensuring the consistency of the final product's quality and its market competitiveness.

[0003] Patent CN221693439U discloses a dispersion device for paint and coating production; it includes a support frame with a slider slidably mounted on it, the slider being connected to a top cover, and a stirring device mounted on the top cover; the stirring device includes a stirring shaft extending along the central axis of the tank, a sliding abutment plate mounted on the stirring shaft, a drive assembly connected to the abutment plate, the drive assembly driving the abutment plate to move up and down along the stirring shaft, a stirring body mounted below the abutment plate, the stirring body being slidably connected to the stirring shaft, and an elastic element being mounted between the abutment plate and the stirring body; the stirring body can move up and down within the tank to disperse the material within the tank, no longer a single stirring method, and significantly improves the dispersion effect and dispersion speed.

[0004] The aforementioned prior art uses a drive assembly to move a stop plate up and down along the stirring shaft, and utilizes the cooperation between the stop plate and an elastic element to adjust the distance between multiple stirring elements, thereby achieving the up-and-down movement of the stirring elements within the tank. This design aims to enhance the dispersion effect and increase the dispersion speed. However, a problem in practical applications is that the stop plate collides with the uppermost stirring element when moving downwards, causing wear between the stirring element and the stop plate. Furthermore, the stirring effect of the multi-stirring element system during the up-and-down dispersion process is poor, making it difficult to achieve ideal uniform dispersion. Therefore, we propose a low-speed dispersion device for paint production. Utility Model Content

[0005] The purpose of this invention is to provide a low-speed dispersion device for paint production, 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 low-speed dispersion device for paint production includes a base, on the top of which are four support columns arranged in a matrix. The four support columns together support a dispersion tank, which is the main working chamber for containing and dispersing paint coatings. The dispersion tank is equipped with a stirring element that can move up and down.

[0008] The stirring component includes a circular moving plate. A first rotating rod is rotatably connected to the center of the bottom of the circular moving plate. Three second rotating rods arranged in a circular array are also rotatably connected to the bottom of the circular moving plate. Each of the first and second rotating rods is equipped with multiple stirring blades. The first and second rotating rods drive the multiple stirring blades to rotate, thereby stirring the raw materials in the dispersion tank. A positioning plate is provided on the top of the circular moving plate. A drive gear is rotatably connected to the center of the bottom of the positioning plate. Three driven gears arranged in a circular array are also rotatably connected to the bottom of the positioning plate. The top ends of the shafts of the drive gear and the driven gears are connected to the bottom of the positioning plate through bearings. A motor for driving the drive gear to rotate is provided in the center of the top of the positioning plate. The motor is powered by an external power source and drives the drive gear to rotate. A U-shaped top plate is provided on the top of the positioning plate.

[0009] The base is equipped with a U-shaped support at the top, and a hydraulic cylinder is located in the middle of the top of the U-shaped support. The hydraulic cylinder is connected to an external hydraulic system. The movable rod of the hydraulic cylinder passes through the top of the U-shaped support and is fixedly connected to the top of the U-shaped top plate. The hydraulic cylinder drives the stirring component to move up and down, so that multiple stirring blades can move up and down in the dispersion barrel, effectively improving the dispersion effect of the raw materials.

[0010] Preferably, the base has mounting holes at the top and near the four corners, which can be used to fix the base to the ground with anchor bolts. The center of the front side of the base has a U-shaped clearance opening, which is beneficial for placing the receiving bucket on the ground and placing the receiving bucket below the discharge pipe.

[0011] Preferably, a feed pipe is provided in the upper middle part of the front side of the dispersion tank, and a pipe cap is fitted at the end of the feed pipe for adding raw materials into the dispersion tank. The pipe opening is equipped with a pipe cap to prevent external contamination.

[0012] Preferably, when the movable rod of the hydraulic cylinder is fully extended, the circular movable plate is positioned above the feed pipe, ensuring that the raw materials added to the dispersion barrel do not fall on top of the circular movable plate.

[0013] Preferably, the bottom of the front side of the dispersion tank is provided with a discharge pipe, and the discharge pipe is provided with a control valve for discharging the dispersed coating, and the control valve is used to adjust the flow rate.

[0014] Preferably, all three driven gears mesh with the driving gear. The bottom end of the driving gear shaft is coaxially connected to the top end of the first rotating rod, and the bottom ends of the three driven gear shafts are coaxially connected to the top ends of the three second rotating rods, respectively. The driving gear drives the three driven gears to rotate, which in turn drives the first rotating rod to rotate. The three driven gears drive the three second rotating rods to rotate, respectively. The size of the driving gear is larger than that of the driven gears, and the three driven gears are the same size. This ensures that the rotational speed of the first rotating rod is less than that of the second rotating rods, allowing the solution in the dispersion tank to be fully dispersed.

[0015] Preferably, the positioning plate has three L-shaped connecting seats arranged in a circular array at its bottom and near its outer edge. The L-shaped connecting seats are detachably connected to the top of the circular moving plate by bolts, which facilitates the assembly and disassembly of the positioning plate and the circular moving plate.

[0016] Preferably, the top of the U-shaped top plate and near the left and right sides are provided with positioning vertical rods, the top of which penetrates through the top of the inner wall of the U-shaped support to the outside, thereby improving the stability of the stirring component when it moves up and down.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This low-speed dispersion device for paint production uses a hydraulic cylinder-driven agitator that moves up and down, avoiding direct collision between the abutment plate and the agitator, reducing internal wear and improving the device's durability and service life.

[0019] 2. This low-speed dispersion device for paint production, through the improved design of the first and second rotating rods combined with multiple stirring blades, enables the device to achieve complex three-dimensional stirring motion, greatly enhancing the dispersion effect, ensuring the uniform distribution of pigments and fillers in the paint matrix, and improving the hiding power and coloring effect of the product.

[0020] 3. This low-speed dispersion device for paint production allows the stirring components to move up and down controllably within the dispersion tank by adjusting the extension and retraction of the hydraulic cylinder. This enables the device to adapt to the production needs of paints and coatings with different viscosities and compositions, enhancing the equipment's versatility and adaptability.

[0028] Please see Figures 1-4 This utility model provides a technical solution:

[0029] A low-speed dispersion device for paint production includes a base 1. The top of the base 1 is provided with four support columns 10 arranged in a matrix. The four support columns 10 together support a dispersion tank 2, which is the main working chamber for containing and dispersing paint coatings. The dispersion tank 2 is provided with a stirring element 5 that can move up and down.

[0030] The stirring component 5 includes a circular moving plate 50. The outer wall of the circular moving plate 50 is 1-2 mm away from the inner wall of the dispersion tank 2 to avoid wear. A first rotating rod 51 is rotatably connected to the center of the bottom of the circular moving plate 50. Three second rotating rods 52 arranged in a circular array are also rotatably connected to the bottom of the circular moving plate 50. Multiple stirring blades 53 are provided on both the first and second rotating rods 51 and 52. The first and second rotating rods 51 and 52 drive the multiple stirring blades 53 to rotate, thereby stirring the raw materials in the dispersion tank 2. The top of the movable plate 50 is provided with a positioning plate 54. The bottom center of the positioning plate 54 is rotatably connected to a drive gear 58. The bottom of the positioning plate 54 is also rotatably connected to three driven gears 59 arranged in a circular array. The top ends of the shafts of the drive gear 58 and the driven gears 59 are connected to the bottom of the positioning plate 54 through bearings. The top center of the positioning plate 54 is provided with a motor 55 for driving the drive gear 58 to rotate. The motor 55 is powered by an external power source and drives the drive gear 58 to rotate. The top of the positioning plate 54 is provided with a U-shaped top plate 56.

[0031] The base 1 is equipped with a U-shaped support 3 at the top, and a hydraulic cylinder 4 is located in the middle of the top of the U-shaped support 3. The hydraulic cylinder 4 is connected to an external hydraulic system. The movable rod of the hydraulic cylinder 4 passes through the top of the U-shaped support 3 and is fixedly connected to the top of the U-shaped top plate 56. The hydraulic cylinder 4 drives the stirring component 5 to move up and down, so that multiple stirring blades 53 can move up and down in the dispersion tank 2, effectively improving the dispersion effect of the raw materials.

[0032] In this embodiment, mounting holes 11 are provided on the top of the base 1 and near the four corners, so that the base 1 can be fixed to the ground by anchor bolts. A U-shaped clearance opening 12 is provided in the middle of the front side of the base 1, which is conducive to placing the receiving bucket on the ground and placing the receiving bucket below the discharge pipe 22.

[0033] Specifically, a feed pipe 20 is provided in the upper middle part of the front side of the dispersion tank 2. The end of the feed pipe 20 is fitted with a pipe cap 21 for adding raw materials into the dispersion tank 2. The pipe opening is equipped with a pipe cap 21 to prevent external contamination.

[0034] Furthermore, when the movable rod of the hydraulic cylinder 4 is fully extended, the circular moving plate 50 is positioned above the feed pipe 20, ensuring that the raw materials added to the dispersion barrel 2 do not fall on top of the circular moving plate 50.

[0035] Furthermore, a discharge pipe 22 is provided at the bottom of the front side of the dispersion tank 2. The discharge pipe 22 is equipped with a control valve for discharging the dispersed coating. The control valve is used to adjust the flow rate.

[0036] Furthermore, all three driven gears 59 mesh with the driving gear 58. The bottom end of the shaft of the driving gear 58 is coaxially connected to the top end of the first rotating rod 51, and the bottom ends of the shafts of the three driven gears 59 are coaxially connected to the top ends of the three second rotating rods 52, respectively. The driving gear 58 drives the three driven gears 59 to rotate, which in turn drives the first rotating rod 51 to rotate. The three driven gears 59 drive the three second rotating rods 52 to rotate, respectively. The size of the driving gear 58 is larger than that of the driven gears 59, and the three driven gears 59 are the same size. This results in the rotational speed of the first rotating rod 51 being less than that of the second rotating rod 52, allowing the solution in the dispersion tank 2 to be fully dispersed.

[0037] Furthermore, the bottom of the positioning plate 54 and near its outer edge are provided with three L-shaped connecting seats 540 arranged in a circular array. The L-shaped connecting seats 540 are detachably connected to the top of the circular movable plate 50 by bolts, which facilitates the assembly and disassembly of the positioning plate 54 and the circular movable plate 50.

[0038] Furthermore, positioning vertical rods 57 are provided at the top of the U-shaped top plate 56 and near the left and right sides. The top of the positioning vertical rods 57 penetrates through the top of the inner wall of the U-shaped bracket 3 to the outside, improving the stability of the stirring component 5 when it moves up and down.

[0039] In this embodiment of the low-speed dispersion device for paint production, ensure the base 1 is stable and fixed to the ground with anchor bolts. Install using mounting holes 11. Ensure the hydraulic and power systems are properly connected, and that the hydraulic cylinder 4 and motor 55 are correctly connected and ready for operation. Open the cap 21 on the feed pipe 20 at the front of the dispersion tank 2, and add the required paint or coating raw materials into the dispersion tank 2 through the feed pipe 20. Close the cap 21 to prevent external contamination. Start the motor 55, which drives the drive gear 58 to rotate. The drive gear 58 drives three driven gears 59 to rotate, which in turn drives the first rotating rod 51 to rotate. The three driven gears 59 drive the three second rotating rods 52 to rotate respectively. The size of the drive gear 58 is larger than that of the driven gears 59, thus making the rotational speed of the first rotating rod 51 less than that of the second rotating rod 52. The rotation speed of the first rotating rod 51 and the second rotating rod 52 drives multiple stirring blades 53 to rotate, thereby stirring the raw materials in the dispersion tank 2 and ensuring that the solution in the dispersion tank 2 can be fully dispersed. The hydraulic system is activated, and the height of the stirring component 5 is adjusted by extending and retracting the movable rod of the hydraulic cylinder 4, so that the stirring component 5 moves up and down in the dispersion tank 2. This allows for thorough three-dimensional stirring of the raw materials in the tank. As needed, the frequency and amplitude of the up and down movement of the stirring component 5 can be adjusted by the hydraulic system, or the stirring speed can be adjusted by the motor 55 to achieve the best dispersion effect. After the dispersion process is completed, the control valve on the discharge pipe 22 at the bottom of the dispersion tank 2 is opened to discharge the evenly dispersed paint into the receiving tank. The equipment is then turned off and the power is cut off. Through the above operations, the low-speed dispersion device for paint production can effectively distribute pigments and fillers evenly in the paint, improving product quality and production efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
