Description

Technical Field

[0001] The utility model relates to the field of coatings, in particular to a mixing device for coating research and development. Background Art

[0002] Paint is a substance that is applied to the surface of an object, can form a complete film and can firmly adhere to the surface of the object. The main components of paint include film-forming substances, solvents, pigments, fillers and various additives. Film-forming substances are a kind of polymer compounds, which can be divided into two categories: natural polymers and synthetic polymers. Solvents play the role of dissolving and dispersing film-forming substances or pigments in paints. After film formation, they will not remain in the paint film but will evaporate completely. Pigments are the secondary film-forming substances in paints. According to their use, they are mainly divided into three types: body pigments, coloring pigments and anti-rust pigments. Additives play a big role in paints, but the amount added is very small. Paint additives are mainly divided into four categories, including dispersants, wetting agents, emulsifiers, etc.

[0003] Due to the different surrounding environments, the service life of paints is different in different environments. In order to research better paints, the paint research and development department needs to mix different materials together for research. The existing mixing devices for paint research and development only mix various raw materials together and stir them. Since some materials are in powder form and some will condense into clumps, they are not easy to disperse when stirred in the mixing device for research and development, which requires a long time of stirring. Otherwise, the stirred paint contains particulate matter, which reduces the quality of the paint.

[0004] Therefore, a mixing device for coating research and development is particularly needed to solve the problems existing in the prior art. Utility Model Content

A fixed ring is installed on the upper part of the rotating shaft, and a plurality of rotating shafts are rotatably arranged on the side of the fixed ring. A stirring plate is sleeved on the outside of the rotating shaft, and a spur gear is installed on the end of the rotating shaft away from the fixed ring. A gear ring is arranged in the mixing barrel, and the gear ring is meshed with the spur gear.

[0007] Furthermore, it also includes planetary gears, connecting rings and scraping rods. The planetary gears are installed on the upper part of the rotating shaft, the connecting rings are installed on the side of the planetary gears, and several scraping rods are installed on the side of the connecting rings. The scraping rods are in contact with the inner wall of the mixing barrel.

[0008] Furthermore, it also includes a reciprocating rod, a filter plate and a ball.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0021] Example 1

[0022] A mixing device for coating research and development, such as Figure 1-Figure 6 As shown, it includes a mixing barrel 1, a cover plate 2, a lower hopper 3, an observation window 4, a support frame 5, a driving motor 6, a spiral blade 7, a conical shell 8, a fixing ring 12, a rotating shaft 13, a stirring plate 14, a spur gear 15 and a gear ring 16. The top of the mixing barrel 1 is movably provided with a cover plate 2, and a plurality of lower hoppers 3 are penetrated through the top of the cover plate 2. The number of the lower hoppers 3 is 3, and can be increased according to actual needs. The side of the mixing barrel 1 is inlaid with an observation window 4, which plays a role in conveniently viewing the internal situation of the mixing barrel 1. A support frame 5 is installed at the bottom of the mixing barrel 1, and a driving motor 6 is arranged in the support frame 5. The output shaft of the driving motor 6 is connected to the rotating shaft through a coupling A spiral blade 7 is arranged on the outer side of the rotating shaft, and the spiral blade 7 plays a stirring role. At the same time, the spiral blade 7 prevents the paint from sinking to the bottom. A conical shell 8 is sleeved on the outer side of the spiral blade 7, and the conical shell 8 is installed at the bottom of the mixing barrel 1. A plurality of holes are opened on the side of the conical shell 8. A fixing ring 12 is installed on the upper part of the rotating shaft. A plurality of rotating shafts 13 are rotatably arranged on the side of the fixing ring 12. A stirring plate 14 is sleeved on the outer side of the rotating shaft 13. A spur gear 15 is installed on the end of the rotating shaft 13 away from the fixing ring 12. A gear ring 16 is arranged in the mixing barrel 1, and the gear ring 16 is meshed with the spur gear 15. The spiral blade 7 is located in the mixing barrel 1, and the mixing barrel 1 is provided with a discharge port.

[0023] like Figure 4 and Figure 6 As shown, it also includes a reciprocating rod 17, a filter plate 18 and a ball 19. The reciprocating rod 17 is sleeved on the top of the rotating shaft. A slide groove is opened on the side of the reciprocating rod 17. The slide groove is spiral. The ball 19 is slidably connected in the slide groove. The filter plate 18 is slidably arranged on the outer side of the reciprocating rod 17, and the ball 19 is in contact with the filter plate 18.

[0024] The coating raw materials to be stirred are poured into the mixing barrel 1 through the lower hopper 3. Different raw materials can be poured through different lower hoppers 3. The driving motor 6 works to drive the rotating shaft to rotate. The rotating shaft drives the spiral blade 7 to rotate. The spiral blade 7 drives the raw materials in the mixing barrel 1 to rotate and stir. The coating raw materials move downward through the filter plate 18. The larger raw materials stay on the filter plate 18, and the smaller raw materials fall downward. The rotation of the rotating shaft drives the fixed ring 12 to rotate. The rotating shaft 13 on the side of the fixed ring 12 rotates. The spur gear 15 at the end of the rotating shaft 13 rotates along the gear ring 16 during rotation, pushing the rotating shaft 13 to rotate around the fixed ring 12, driving the stirring plate 14 to rotate, and the stirring plate 14 contacts the filter plate 18 to scrape off the raw materials stuck at the bottom of the filter plate 18 and break up the raw materials in contact with it. The raw materials fall onto the spiral blade 7 and are fully mixed as the spiral blade 7 rotates and moves.

The scraper rods 11 are in contact with the inner wall of the mixing barrel 1, and the scraper rods 11 scrape off the sticky paint on the inner wall of the mixing barrel 1.

[0027] When the rotating shaft rotates, the planetary gear 9 is driven to rotate, and the connecting ring 10 on the side of the planetary gear 9 rotates, driving the scraper rod 11 to rotate. The scraper rod 11 contacts the inner wall of the mixing barrel 1, and scrapes off the paint stuck to the inner wall of the mixing barrel 1, thereby preventing the paint from sticking to the inner wall of the mixing barrel 1. When the rotating shaft rotates, the reciprocating rod 17 is driven to rotate, and the ball 19 on the outer surface of the reciprocating rod 17 slides, driving the filter plate 18 to shake up and down, and the paint on the filter plate 18 moves with the shaking, thereby promoting the dispersion of agglomerated paint raw materials.
