Abstract
Description
Technical Field
[0001] This utility model relates to an experimental coating mixing and stirring device. Background Technology
[0002] In the process of research and innovation, enterprises need to develop coatings with different properties. In the laboratory, the coatings are mixed using a coating mixing and stirring device to obtain finished coating samples. Then, a series of performance parameters are tested, and continuous improvements are made until the best-performing finished product is obtained.
[0003] Existing experimental coating mixing devices use two grippers to hold the mixing drum between the left and right sides, placing the drum below the stirring shaft. However, when the outer wall of the mixing drum has a rim with grab holes for easy lifting, the two grippers cannot stably hold the mixing drum. Furthermore, aligning the center of the mixing drum with the central axis of the stirring rod is difficult. Even a slight deviation can cause the stirring rod to hit the inner wall of the mixing drum when rotating, causing the mixing drum to shake. In severe cases, the mixing drum may tip over and the stirring rod may bend, posing a safety hazard. Summary of the Invention

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0014] The specific technical solution of this utility model is as follows:
[0015] like Figures 1 to 3 As shown, an experimental coating mixing and stirring device includes a workbench 1 and a mixing tank 2. The side wall of the mixing tank 2 is provided with an outwardly extending edge 3. The workbench 1 is provided with a support column 4 and a groove 5. The groove 5 is adapted to the bottom of the mixing tank 2. The top of the support column 4 is provided with an electric lifting rod 17. The side of the support column 4 is provided with a vertical guide rail 6. A first bracket 7 and a second bracket 8 are slidably provided on the vertical guide rail 6. The first bracket 7 is connected to the electric lifting rod 17. A rotary motor 9 is provided on the first bracket 7. A stirring rod 10 is provided at the bottom of the rotary motor 9. A positioning sleeve 11 is provided on the second bracket 8. The positioning sleeve 11 is fitted on the outside of the mixing tank 2. The edge 3 of the mixing tank 2 is located between the positioning sleeve 11 and the workbench 1. The central axis of the stirring rod 10 is located at the center of the groove 5 and the positioning sleeve 11.
[0016] Symmetrical gripping holes 12 are provided on the aforementioned edge 3 for easy lifting. Corresponding limiting holes 13 are provided on the worktable 1. The bottom of the positioning sleeve 11 is provided with corresponding limiting pins 14. The limiting pins 14 pass through the gripping holes 12 and are inserted into the limiting holes 13. Specifically, this effectively prevents the mixing tank 2 from rotating freely during the mixing process and limits the mixing tank 2.
[0017] The lower end of the stirring rod 10 is provided with a plurality of stirring blades 15 evenly arranged in a circular pattern. The plurality of stirring blades 15 have the same structure, and there is a gap between the edge of the stirring blades 15 and the inner wall of the stirring tank 2. Specifically, this prevents the stirring blades 15 from contacting the inner wall of the stirring tank 2 during the stirring process.
[0018] The top of the above-mentioned mixing tank 2 is provided with an opening 16, and a sealing cover 18 is provided on the opening 16. The edge of the sealing cover 18 abuts against the positioning sleeve 11, and a through hole is provided in the center of the sealing cover 18. The stirring rod 10 passes through the through hole. Specifically, the sealing cover 18 can effectively prevent the material in the mixing tank 2 from overflowing, and at the same time, the sealing cover 18 applies a downward pressure to the positioning sleeve 11.
[0019] The aforementioned mixing tank 2 is cylindrical, and the groove 5 is adapted to the shape of the mixing tank 2.
[0020] In use, place the mixing tank 2 with edge 3 into the groove 5 of the workbench 1, aligning the gripping hole 12 on edge 3 with the limiting hole 13 on the workbench 1. Then, move the second support 8 down along the vertical guide rail 6, causing the positioning sleeve 11 on the second support 8 to move down. The positioning sleeve 11 is fitted onto the outside of the mixing tank 2, and the limiting pin 14 at the bottom of the positioning sleeve 11 passes through the gripping hole 12 and is inserted into the corresponding limiting hole 13. After that, start the electric lifting rod 17, which drives the first support 7 down along the vertical guide rail 6. The first support 7 is moved so that the rotary motor 9 and the stirring rod 10 on the first support 7 are moved down as a whole. The stirring blade 15 at the lower end of the stirring rod 10 extends into the mixing tank 2. The sealing cover 18 on the stirring rod 10 closes the opening 16 of the mixing tank 2. The edge of the sealing cover 18 presses down on the positioning sleeve 11. Finally, the rotary motor 9 is started, and the stirring rod 10 drives the stirring blade 15 to stir and mix the material in the mixing tank 2. The mixing tank 2 with the edge 3 is fixed by the upper and lower clamping method, so there is no need to align the center, which is convenient and quick to use.
[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
