Description

Technical Field

[0001] This utility model relates to the field of silicone sealant mixing technology, specifically to a stirring device and a silicone sealant mixing device. Background Technology

[0002] Silicone sealant, also known as silicone sealant, is a high-performance elastic sealing material with polyorganosiloxane (mainly polydimethylsiloxane) as its main component.

[0003] The production of silicone sealant utilizes a dual planetary mixer, whose mixing structure consists of a spiral scraper blade and a vertical dispersing blade. The spiral scraper blade typically has a detachable scraper fixed to its bottom by multiple bolts. However, over long-term use, the scraper blade is prone to wear, causing the gap between its bottom and the bottom of the container to gradually increase. Because the existing structure lacks a convenient adjustment mechanism, it is impossible to adjust the scraper position downwards in a timely manner to compensate for wear, making it difficult to maintain an ideal scraping gap and causing inconvenience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stirring device and a silicone adhesive mixing device, so that the stirring bottom scraper of the silicone adhesive mixer has an adjustment function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stirring device, comprising a stirring paddle connected to a mixer body, a base frame fixedly connected to the bottom of the stirring paddle, and a bottom scraper connected to the bottom of the base frame. A sleeve is fitted on the outer side of the bottom of the base frame, and the bottom scraper is fixedly installed with the sleeve. A first threaded rod is rotatably connected to the bottom of the inner wall of the sleeve. One end of the first threaded rod passes through the base frame and is threadedly connected to the base frame. A protective structure is connected between the base frame and the sleeve.

[0006] Furthermore, the protective structure includes a protective box, a rectangular frame is fixedly connected to the top of the base frame, the protective box is fitted on the outside of the rectangular frame, and the first threaded rod is located on the inner wall of the protective box.

[0007] Furthermore, the top surface of the protective box is threaded with a second threaded rod, the top of the first threaded rod has a groove, the second threaded rod passes through one end of the protective box and is threadedly connected to the groove, and the end of the second threaded rod located outside the protective box is fixedly connected to an anti-detachment platform, and the outer side of the anti-detachment platform has anti-slip texture.

[0008] Furthermore, protruding strips are fixedly connected to both sides of the outer wall of the protective box.

[0009] Furthermore, the inner wall bottom surface of the sleeve is fixedly connected to two symmetrically arranged positioning posts, which pass through the base frame and are slidably connected to it. The two positioning posts are located on both sides of the first threaded rod and on the inner side of the protective box.

[0010] Furthermore, a scale line is provided on the outer side of one of the positioning posts.

[0011] Furthermore, a flexible sleeve is provided between the sleeve base and the base frame. One end of the flexible sleeve is fixedly connected to the outer side of the sleeve base, and the other end is fixedly connected to the top surface of the base frame.

[0012] Another objective of this invention is to provide a silicone sealant mixing device, including the aforementioned stirring device and a mixer body. This facilitates the compensation and adjustment of the gap between the bottom scraper in the stirring paddle and the bottom surface of the mixing tank caused by wear.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes the interaction between a sleeve and a first threaded rod to drive the sleeve connected to the bottom scraper to rise and fall with the rotation of the first threaded rod, thereby compensating for the gap caused by wear between the bottom scraper and the bottom surface of the mixing tank. This design not only helps maintain efficient mixing but also avoids frequent replacement of the bottom scraper due to excessive gaps, improving maintenance convenience and equipment lifespan. The structure is simple, easy to operate, and highly practical. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figures 1 to 5As shown, a mixing device includes a mixing paddle 2 connected to a mixer body 1, a base frame 3 fixedly connected to the bottom of the mixing paddle 2, and a bottom scraper 5 connected to the bottom of the base frame 3. A sleeve 4 is fitted on the outer side of the bottom of the base frame 3. The bottom scraper 5 is fixedly installed with the sleeve 4. A first threaded rod 10 is rotatably connected to the bottom of the inner wall of the sleeve 4. One end of the first threaded rod 10 passes through the base frame 3 and is threadedly connected to the base frame 3. A protective structure is connected between the base frame 3 and the sleeve 4.

[0018] like Figure 1 As shown, the stirring device and silicone rubber mixing device in this utility model are similar in structure to existing dual planetary power mixers, such as the dual planetary power mixer disclosed in patent publication number CN223159150U. The main improvement of this utility model is that the stirring bottom scraper of the silicone rubber mixer has an adjustable function, such as... Figures 1 to 5 As shown, when the stirring device and silicone rubber mixing device of this utility model are in use, after the mixer body 1 is started, its internal motor (existing technology) rotates, which drives the stirring paddle 2 to rotate, which drives the sleeve 4 on the outside of the base frame 3 to rotate, and the sleeve 4 drives the bottom scraper 5 to rotate, so as to stir and mix the silicone rubber material in the mixer body 1.

[0019] After the bottom scraper 5 has been used for a period of time, the stirring device can be cleaned first, and the wear of the bottom scraper 5 can be checked. When adjusting the bottom scraper 5, the first threaded rod 10 can be rotated, which will drive the first threaded rod 10 to rotate on the base frame 3. The first threaded rod 10 is threadedly connected to the base frame 3 and rotatably connected to the sleeve 4. Therefore, when the first threaded rod 10 rotates, it can push the sleeve 4 to descend on the outside of the base frame 3, thereby driving the bottom scraper 5 to descend, thus filling the gap between the bottom scraper 5 and the inner wall of the mixing tank.

[0020] Through the cooperation of the sleeve 4 and the first threaded rod 10, the sleeve 4 connected to the bottom scraper 5 can be adjusted by the rotation of the first threaded rod 10, thereby facilitating the elimination of the gap between the bottom scraper 5 and the bottom surface of the mixing tank, resulting in high mixing efficiency and avoiding the need to directly replace the worn bottom scraper 5.

[0021] like Figure 3 and Figure 4 As shown, the protective structure includes a protective box 6, a rectangular frame 8 is fixedly connected to the top of the base frame 3, the protective box 6 is sleeved on the outside of the rectangular frame 8, and the first threaded rod 10 is located on the inner wall of the protective box 6.

[0022] Specifically, the protective box 6 can be fitted onto the outside of the rectangular frame 8, so that the protective box 6 can protect the first threaded rod 10 and prevent silicone adhesive material from adhering to the first threaded rod 10 during the mixing process.

[0023] like Figure 3 and Figure 4As shown, the top surface of the protective box 6 is threaded with a second threaded rod 12. The top of the first threaded rod 10 is provided with a groove 11. One end of the second threaded rod 12 passes through the protective box 6 and is threadedly connected to the groove 11. The other end of the second threaded rod 12 located outside the protective box 6 is fixedly connected with an anti-detachment platform 13. The outer side of the anti-detachment platform 13 is provided with anti-slip texture.

[0024] Specifically, the protective box 6 is fitted onto the outside of the rectangular frame 8, and then the second threaded rod 12 is threaded through the protective box 6 and connected to the groove 11 on the outside of the first threaded rod 10. This makes the installation of the protective box 6 more stable and also makes the first threaded rod 10 more tightly compressed.

[0025] like Figure 2 As shown, protruding strips 7 are fixedly connected to both sides of the outer wall of the protective box 6. The protruding strips 7 facilitate the removal and handling of the protective box 6.

[0026] like Figure 3 and Figure 4 As shown, two symmetrically arranged positioning posts 9 are fixedly connected to the bottom surface of the inner wall of the sleeve 4. The positioning posts 9 pass through the base frame 3 and are slidably connected to it. The two positioning posts 9 are located on both sides of the first threaded rod 10 and on the inner side of the protective box 6.

[0027] Specifically, when the sleeve 4 is raised or lowered, the sleeve 4 will drive the positioning pins 9 to rise or fall. The positioning pins 9 are designed to ensure that the sleeve 4 is stable when raised or lowered outside the base frame 3. Furthermore, the two positioning pins 9 are located inside the protective box 6, which can effectively prevent materials from adhering to the positioning pins 9.

[0028] like Figure 3 and Figure 4 As shown, a scale line 14 is provided on the outer side of one of the positioning posts 9. The scale line 14 is provided so that the lifting distance can be observed by the scale line 14 when the sleeve 4 is raised and lowered, so as to ensure the adjustment accuracy of the gap of the bottom scraper 5.

[0029] like Figure 5 As shown, a flexible sleeve 15 is also provided between the sleeve 4 and the base frame 3. One end of the flexible sleeve 15 is fixedly connected to the outer side of the sleeve 4, and the other end is fixedly connected to the top surface of the base frame 3.

[0030] Specifically, when the agitator 2 is agitating materials, the flexible sleeve 15 protects the sliding gap between the sleeve 4 and the base frame 3, effectively preventing materials from falling directly into the sliding gap between the sleeve 4 and the base frame 3. The flexible sleeve 15 is flexible, and a certain margin can be set if necessary to ensure smooth lifting and lowering of the sleeve 4 outside the base frame 3.

[0031] In addition, before adjusting the distance between the sleeve 4 and the bottom scraper 5, the material on the mixer body 1 and the stirring paddle 2 should be completely rinsed off, so as to facilitate the detection of wear gaps and adjustment operations.

[0032] Another objective of this utility model is to provide a silicone adhesive mixing device, including the above-mentioned stirring device, and also including a mixer body 1, such as the dual planetary power mixer disclosed in the patent publication number CN223159150U.

[0033] Although the present invention 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 invention should be included within the protection scope of the present invention.
