Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-based paint production technology, specifically a stirring device for water-based paint production. Background Technology
[0002] Water-based paint is a type of coating that uses water as a diluent and does not contain organic solvents. It produces a full, crystal-clear, and flexible paint film, and is also characterized by water resistance, abrasion resistance, aging resistance, yellowing resistance, fast drying, and ease of use. The production of water-based paint mainly relies on mixing its various components through stirring to ensure uniform mixing. Stirring is an essential step in the preparation of water-based paint. Currently used stirring equipment consists of a frame, a drive mechanism mounted on the frame, and a stirring rod. The bottom of the stirring rod is usually in the form of a straight line, a cross, a whisk, or a paddle.
[0003] While the uniformity of water-based paint mixing can be improved by moving the position of the mixing shaft, i.e., the mixing blades, the movement method is relatively simple and cannot effectively improve the uniformity of water-based paint mixing. To improve this problem, some existing structures use a movable mixing rod. Two sets of power sources are used, one to drive the mixing rod to rotate and mix, and the other to drive the mixing rod to move at a constant speed in the mixing chamber to improve the uniformity of mixing. Although it can improve the uniformity of mixing, it consumes more energy and the production cost increases accordingly.
[0004] Based on this, a stirring device for water-based paint production is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0007] A stirring device for water-based paint production includes a stirring shell, a stirring chamber disposed in the middle of the stirring shell, a stirring component disposed inside the stirring chamber, and a purification component disposed at the upper end of the stirring chamber.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0017] 1. This utility model, through the setting of the stirring component, through the meshing relationship of the sun gear and planetary gears, and driven by a single rotary motor, can drive multiple stirring rods to rotate simultaneously.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] In one embodiment, such as Figures 1-4 As shown, a stirring device for water-based paint production includes a stirring shell 1, a stirring chamber 6 is arranged in the middle of the stirring shell 1, a stirring component is arranged inside the stirring chamber 6, and a purification component is arranged at the upper end of the stirring chamber 6.
[0025] The stirring assembly includes a gearbox 8, a rotary motor 7 is fixedly connected to the middle of the upper surface of the gearbox 8, a sun gear 9 is arranged in the middle of the gearbox 8, a number of planetary gears 11 are meshed around the sun gear 9, the output end of the rotary motor 7 passes through the upper surface of the gearbox 8 and is fixedly connected to the middle of the sun gear 9, and a stirring rod 10 is fixedly connected to the middle of the lower surface of the sun gear 9 and all the planetary gears 11.
[0026] In this embodiment, the rotary motor 7 starts and drives the sun gear 9 to rotate. Then, the rotation of the sun gear 9 drives all the planetary gears 11 to revolve together inside the gearbox 8, thereby driving all the stirring rods 10 to start stirring inside the stirring chamber 6.
[0027] In one embodiment, such as Figure 3 As shown, the gearbox 8 has internal tooth grooves 12 arranged around its inner perimeter, and the internal tooth grooves 12 mesh with the adjacent planetary gears 11.
[0028] In one embodiment, such as Figure 4As shown, the lower end of the circulating fan 13 is fixedly connected to one side of the upper surface of the mixing chamber 6, and the lower end of the circulating fan 13 extends through the interior of the mixing chamber 6. The upper end of the circulating fan 13 is fixedly connected to an air duct 14, and the upper end of the air duct 14 extends through one side of the upper surface of the mixing shell 1 and is fixedly connected to a purification box 5. A filter assembly is installed on one side of the purification box 5. When the circulating fan 13 starts, it draws harmful gases generated during the preparation of water-based paint into the interior of the air duct 14, and then into the interior of the purification box 5. Subsequently, the gases are discharged after being filtered through layers of filter elements 15, 16, and 17. In practical applications, the circulating fan has more than one air inlet, but one air inlet is located inside the mixing chamber. The mixing chamber is sealed, but the outer chamber is not sealed. The principle is that air circulation inside the mixing chamber is achieved through two air inlets, and a filter assembly is installed at the outlet to filter the air circulating from the mixing chamber.
[0029] In one embodiment, such as Figure 4 As shown, the filter assembly includes a first filter element 15, and a second filter element 16 and a third filter element 17 are sequentially arranged on one side of the first filter element 15. The first filter element 15, the second filter element 16 and the third filter element 17 are all slidably connected to the inside of the purification box 5.
[0030] In one embodiment, such as Figure 2 As shown, a feed pipe 4 is provided on one side of the upper surface of the mixing shell 1. The lower end of the feed pipe 4 penetrates the upper surface of the mixing shell 1 and is fixedly connected to one side of the upper surface of the adjacent mixing chamber 6. Water-based paint raw materials are poured into the interior of the mixing chamber 6 through the feed pipe 4.
[0031] In one embodiment, such as Figure 2 As shown, a feeding pipe 3 is provided below the mixing shell 1. The upper end of the feeding pipe 3 penetrates the lower surface of the mixing shell 1 and is fixedly connected to the lower middle part of the mixing chamber 6. A solenoid valve is provided at the upper end of the feeding pipe 3. After the preparation is completed, the solenoid valve above the feeding pipe 3 is opened to discharge the water-based paint, thus completing the production.
[0032] In one embodiment, such as Figure 1 As shown, a base 2 is fixedly connected to the lower outer side of the stirring shell 1.
[0033] The above embodiment discloses a stirring device for water-based paint production. Water-based paint raw materials are poured into the stirring chamber 6 through the feed pipe 4. At this time, the rotary motor 7 starts, driving the sun gear 9 to rotate. The rotation of the sun gear 9 then drives all the planetary gears 11 to revolve within the gearbox 8, thereby driving all the stirring rods 10 to begin stirring within the stirring chamber 6. Simultaneously, the circulating fan 13 starts, drawing harmful gases generated during water-based paint preparation into the air duct 14, and then into the purification chamber 5. These gases are then filtered through the first filter element 15, the second filter element 16, and the third filter element 17 before being discharged. After preparation is complete, the solenoid valve above the discharge pipe 3 opens, discharging the water-based paint and completing the production process.
[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
