[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Reference Figure 1 - Figure 3This utility model provides an embodiment of a paint mixing device, comprising a support frame 1, a mixing tank 2 fixedly connected to the top of the support frame 1, a discharge pipe 3 fixedly connected to the bottom surface of the mixing tank 2, a feeding component 4 provided on the top surface of the mixing tank 2, and a scraping component 5 provided inside the mixing tank 2. The scraping component 5 includes a motor 51 fixedly connected to the top surface of the mixing tank 2, a threaded rod 52 fixedly connected to the output shaft surface of the motor 51, a threaded sleeve 53 threadedly connected to the surface of the threaded rod 52, and connecting rods 54 uniformly fixedly connected to the surface of the threaded sleeve 53. An annular plate 55 is fixedly connected to the other end surface of the connecting rod 54. An annular scraper 56 is fixedly connected to the end surface of the annular plate 55 away from the connecting rod 54. Guide plates 57 are uniformly fixedly connected to the inner wall surface of the mixing box 2. Guide grooves 58 are uniformly opened on the surfaces of the annular plate 55 and the annular scraper 56. The output shaft of the motor 51 drives the threaded rod 52 to start rotating. Since the threaded rod 52 is threadedly connected to the threaded sleeve 53, when the threaded rod 52 rotates, the threaded sleeve 53 will move along the axial direction of the threaded rod 52. As the threaded sleeve 53 moves, the connecting rod 52 moves along the axial direction of the threaded rod 52. Rod 54 drives the annular plate 55 and annular scraper 56 to move accordingly. One end of the annular scraper 56 is in close contact with the inner wall of the mixing box 2. Therefore, when the annular scraper 56 moves, it scrapes the inner wall of the mixing box 2, ensuring that the paint raw materials adhering to the inner wall are fully mixed, avoiding waste of raw materials and uneven mixing. At the same time, the guide plates 57 evenly arranged on the inner wall of the mixing box 2 guide the movement of the annular plate 55 and annular scraper 56. After mixing is completed, the valve of the discharge pipe 3 is opened, and the mixed paint will flow out from the discharge pipe 3 for subsequent use. During the process, the annular plate 55 and the annular scraper 56 continue to scrape the inner wall of the mixing box 2, causing the paint material adhering to the inner wall to be discharged. The threaded rod 52 is rotatably connected between the top inner wall and the bottom inner wall of the mixing box 2. The annular plate 55 is set inside the mixing box 2. The surface of the annular scraper 56 away from the annular plate 55 abuts against the inner wall surface of the mixing box 2. At least four guide plates 57 are provided. The guide plates 57 are all vertically fixedly connected to the inner wall surface of the mixing box 2. The annular plate 55 and the annular scraper 56 are slidably connected to the surface of the guide plate 57 through the guide groove 58.
[0023] Reference Figure 1 - Figure 3The feeding assembly 4 includes feeding buckets 41 that are uniformly fixed and connected to the top surface of the mixing tank 2. Each feeding bucket 41 has a viewing window 42 on its surface and a scale strip 43 on its surface. By adding different types of paint raw materials into each feeding bucket 41, the viewing window 42 and scale strip 43 on the surface of the feeding bucket 41 allow the operator to clearly observe the amount and type of raw materials in the bucket, ensuring the accuracy and consistency of each feeding. After adding, the valves inside all feeding buckets 41 are opened, allowing the raw materials inside the feeding buckets 41 to fall into the mixing tank 2. Both the discharge pipe 3 and the inside of the feeding buckets 41 are equipped with valves. There are at least two feeding buckets 41. The top of each feeding bucket 41 is open, and the viewing window 42 is located on the outside of the feeding bucket 41.
[0024] Working Principle: During operation, the operator first adds different types of paint raw materials into each feeding bucket 41. The viewing window 42 and scale bar 43 on the surface of the feeding bucket 41 allow the operator to clearly observe the amount and type of raw materials inside, ensuring accuracy and consistency in each feeding. After adding, the valves inside all feeding buckets 41 are opened, allowing the raw materials inside the feeding buckets 41 to fall into the mixing box 2. Next, the motor 51 is started. The output shaft of the motor 51 drives the threaded rod 52 to rotate. Because the threaded rod 52 is threadedly connected to the threaded sleeve 53, when the threaded rod 52 rotates, the threaded sleeve 53 moves along the axial direction of the threaded rod 52. As the threaded sleeve 53 moves... The connecting rod 54 drives the annular plate 55 and the annular scraper 56 to move as well. One end of the annular scraper 56 is in close contact with the inner wall of the mixing box 2. Therefore, when the annular scraper 56 moves, it scrapes the inner wall of the mixing box 2 to ensure that the paint raw materials adhering to the inner wall are fully mixed, avoiding waste of raw materials and uneven mixing. At the same time, the guide plates 57 evenly arranged on the inner wall of the mixing box 2 guide the movement of the annular plate 55 and the annular scraper 56. After mixing is completed, the valve of the discharge pipe 3 is opened, and the mixed paint will flow out from the discharge pipe 3 for subsequent use. During the discharge process, the annular plate 55 and the annular scraper 56 continue to scrape the inner wall of the mixing box 2, so that the paint raw materials adhering to the inner wall are also discharged.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
