[0034] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0035] In addition, the term "and / or" in this article is only a relational description of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after, unless otherwise specified.

[0036] See the attached Figure 1 and the attached Figure 2As shown in the figure, the stirring device for preparing the fireproof sticker in this embodiment includes a container 2 for containing the material to be stirred. A stirring mechanism 3 is arranged inside the container 2 to stir and mix the material in the stirring container 2. A driving mechanism 1 is arranged above the stirring container 2. The driving mechanism 1 is connected to the stirring mechanism 3, and the driving mechanism 1 can drive the stirring mechanism 3 to rotate, and stir and mix the material in the container 2 during the rotation process.

[0037] In some embodiments, the driving mechanism 1 includes a driving motor 11. The driving motor 11 is arranged on the top of the container 2 through a fixing frame 13. The driving shaft 12 of the driving motor 11 penetrates through the container 2 and is detachably connected to the stirring shaft 34. The stirring shaft 34 is driven to rotate by the driving motor 11, and then the stirring mechanism 3 is driven to rotate and stir.

[0038] In some embodiments, a feeding port 4 is arranged on the upper side surface of the container 2 for adding material into the container 2. A cover plate is arranged on the feeding port 4 to block the feeding port 4 during the stirring process, which can effectively prevent the material from splashing out of the container 2 during the stirring process.

[0039] In some embodiments, the bottom of the container 2 is an arc surface, and a discharge port 5 is arranged at the lowest point of the arc surface. In the non-stirring state, the material can gather towards the discharge port 5 due to the action of gravity, which is convenient for discharging the material after stirring.

[0040] In some embodiments, the material of the container 2 is stainless steel or transparent glass. When the material is transparent glass, during the stirring process, the staff can observe the stirring situation in the container 2 at any time, and it is convenient to observe whether the container 2 is cleaned when cleaning the container 2. When the material is stainless steel, the firmness of the container 2 can be improved and the risk of breakage can be reduced.

[0041] In some embodiments, the stirring mechanism 3 includes a stirring shaft 34. Stirring components are arranged on the stirring shaft 34. The stirring shaft 34 is detachably connected to the driving mechanism 1, and the driving mechanism 1 can drive the stirring shaft 34 to rotate. The stirring components can be driven to rotate during the rotation process of the stirring shaft 34. By detachably connecting the stirring shaft 34 and the driving mechanism 1, the stirring shaft 34 can be replaced according to the actual stirring situation, and then the stirring components connected to the stirring shaft 34 can be replaced. On the other hand, the stirring components can also be disassembled for cleaning by disassembling the stirring shaft 34.

[0042] See the appendix Figures 2 to 4As shown, in some embodiments, the stirring assembly includes a first stirring assembly 31, and the first stirring assembly 31 is connected to one end of the stirring shaft 34 away from the driving mechanism 1. The first stirring assembly 31 includes a linkage rod, and the linkage rod is arranged close to the inner wall of the container 2. Specifically, the linkage rod includes a side wall linkage rod 312 close to the side wall of the container 2 and a bottom wall linkage rod 311 close to the bottom wall of the container 2, and the radian of the bottom wall linkage rod 311 is adapted to the radian of the bottom wall of the container 2. One end of the bottom wall linkage rod 311 is connected to the stirring shaft 34, and the other end is connected to the side wall linkage rod 312. The stirring shaft 34 drives the bottom wall linkage rod 311 and the side wall linkage rod to rotate along the inner wall of the container 2, so as to stir the materials in the container 2.

[0043] In some embodiments, a plurality of patches 315 are arranged on the linkage rod, and the patches 315 are attached to the inner wall of the container 2. During the stirring process, the patches 315 can scrape off the materials attached to the wall of the container 2 for stirring, preventing the materials from adhering to the container wall without being stirred during the stirring process, resulting in uneven stirring of the materials.

[0044] In some other embodiments, there is a gap between the patch 315 and the inner wall of the container 2, which can prevent the patch 315 from rubbing against the inner wall of the container 2 and shortening the service life of the patch 315 and the container 2. When there is a gap between the patch 315 and the inner wall of the container 2, when the material on the inner wall of the container 2 has a certain thickness, that is, the material thickness is greater than the gap width, the patch 315 can scrape off the material on the inner wall of the container 2. While ensuring that the material can be scraped off in time, it can also ensure that there is no friction between the patch 315 and the container 2.

[0045] In some embodiments, a connecting piece 313 is integrally arranged on the linkage rod, and the connecting piece 313 is detachably connected to the patch 315. A waist-shaped hole 314 is arranged on the connecting piece 313, and a bolt passes through the waist-shaped hole 314 to connect with the patch 315. Through the arrangement of the waist-shaped hole 314, the distance between the patch 315 and the inner wall of the container 2 can be adjusted, so that the stirring mechanism 3 can be adapted to containers 2 of different sizes.

[0046] In some embodiments, the patch 315 includes a scraping portion for scraping off the materials on the inner wall of the container 2, and the shape of the scraping portion is adapted to the shape of the corresponding inner wall, so that the scraping portion can effectively scrape off the materials.

[0047] In some embodiments, a plurality of patches 315 are arranged and are connected to the linkage rod in sequence.

[0048] In some embodiments, the stirring assembly includes a second stirring assembly 32. The second stirring assembly 32 includes a stirring disk 321 disposed in the middle of the stirring shaft 34. The ratio of the radius of the stirring disk 321 to the radius of the container 2 is 0.5 to 0.8, preferably 0.6 to 0.7. The stirring shaft 34 penetrates through the center of the stirring disk 321 and is detachably connected to the stirring disk 321. The stirring shaft 34 drives the stirring disk 321 to rotate, and stirs the material during the rotation.

[0049] In some embodiments, multiple sets of the second stirring assemblies 32 are provided. The multiple sets of stirring disks 321 are arranged in sequence along the stirring shaft 34. By providing the multiple sets of second stirring assemblies 32, the stirring effect is improved.

[0050] In some embodiments, a plurality of stirring teeth are provided at the edge of the stirring disk 321. The stirring teeth include upper-side stirring teeth 322. The upper-side stirring teeth 322 are bent upward with respect to the stirring disk 321 as a reference plane, and can stir the material on the upper side of the stirring disk 321, improving the stirring effect of the second stirring assembly 32.

[0051] In some embodiments, the stirring teeth include lower-side stirring teeth 323. The lower-side stirring teeth 323 are bent downward with respect to the stirring disk 321 as a reference plane, and can stir the material on the lower side of the stirring disk 321, improving the stirring effect of the second stirring assembly 32.

[0052] In some embodiments, the upper-side stirring teeth 322 and the lower-side stirring teeth 323 are arranged at intervals in sequence. The upward bending angle range of the upper-side stirring teeth 322 with respect to the stirring disk 321 is 30 to 90 degrees, and the downward bending angle of the lower-side stirring teeth 323 with respect to the stirring disk 321 is 30 to 90 degrees. The specific bending angles of the upper-side stirring teeth 322 and the lower-side stirring teeth 323 may be the same or different, depending on the actual situation.

[0053] The first stirring assembly 31 or the second stirring assembly 32 can be provided alone, or both the first stirring assembly 31 and the second stirring assembly 32 can be provided at the same time. By driving the first stirring assembly 31 and the second stirring assembly 32 simultaneously through one stirring shaft 34, the number of the stirring shaft 34 and the driving mechanism 1 can be reduced, the components of the stirring device can be simplified, the production cost of the equipment can be reduced, and it is convenient for the staff to operate.

[0054] See the appendix Figure 3 and the appendix Figure 5As shown, in some embodiments, the stirring mechanism 3 further includes a third stirring component 33. The third stirring component 33 is detachably connected to the stirring shaft 34, and the third stirring component 33 can be driven to rotate by the stirring shaft 34. The ratio of the stirring radius of the third stirring component 33 to the radius of the container 2 is 0.2 - 0.5, preferably 0.3 - 0.4. The stirring radius is the rotation radius of the third stirring component 33 rotating around the stirring shaft 34.

[0055] In some embodiments, the third stirring component 33 includes two stirring blades 331 arranged vertically. The included angle between the stirring blade 331 and the stirring shaft 34 is 30 - 60 degrees, preferably 45 degrees. By arranging the stirring blade 331 obliquely relative to the stirring shaft 34, during the stirring process, the material can move downward or upward along the stirring blade 331. See the attached Figure 5 As shown, when the stirring shaft 34 rotates clockwise, the material moves downward along the stirring blade 331. When the stirring shaft 34 rotates counterclockwise, the material can move upward along the stirring blade 331, so that the material near the stirring shaft 34 can tumble up and down, driving the material to be stirred.

[0056] In some embodiments, a groove 332 is provided on the side of the stirring blade 331 close to the stirring shaft 34. The material can pass through the groove 332, which can reduce the stirring resistance of the material to the stirring blade and improve the stirring speed.

[0057] See the attached Figure 6 As shown, in some other embodiments, the third stirring component 33 includes a plurality of stirring rods 333. Both ends of the stirring rod 333 are fixedly connected to the stirring disc 321 respectively. During the rotation of the stirring disc 321, the stirring rod 333 is driven to rotate, and then the material between two adjacent stirring discs 321 can be driven to rotate.

[0058] In some embodiments, one set of the third stirring component 33 is provided, and two sets of the second stirring components 32 are provided. The third stirring component 33 is arranged between the two sets of the second stirring components 32. There is a stirring blank area between the two sets of the second stirring components 32, and the stirring effect is relatively poor. By arranging the third stirring component 33, the area between the two sets of the second stirring components 32 is stirred, improving the overall stirring effect of the stirring mechanism 3.

[0059] In some embodiments, multiple sets of the third stirring component 33 are provided, and they are arranged at intervals along the stirring shaft 34 with multiple sets of the second stirring components 32.

[0060] See the attached Figure 7As shown, through the setting of the second stirring assembly 32, the ratio of the radius of the stirring disk 321 to the radius of the container 2 is 0.5 to 0.8, which improves the stirring effect of the stirring mechanism 3 on the first area 35 close to the container 2. Through the setting of the third stirring assembly 33, the ratio of the stirring radius of the third stirring assembly 33 to the radius of the container 2 is 0.2 to 0.5, which enhances the stirring effect of the stirring mechanism 3 on the second area 36 close to the stirring shaft 34. The first stirring assembly 31 can timely scrape off the materials adhering to the inner wall of the container 2 for stirring. Therefore, the stirring mechanism 3 stirs the materials in the container 2 in all directions without dead angles by setting the first stirring assembly 31, the second stirring assembly 32, and the third stirring assembly 33, and has a good stirring effect.
