Abstract
Description
Technical Field
[0001] The utility model relates to the field of stirring equipment, in particular to stirring equipment for the production of polyurethane potting glue. Background Art
[0002] The stirring process in the production of polyurethane potting glue is one of the key steps to ensure product quality and performance. The use of corresponding stirring equipment can ensure the full mixing and uniformity of the raw material components to improve the stability and performance of the product and reduce the generation of bubbles and impurities.
[0003] When the mixing equipment is used to mix the raw materials of polyurethane potting glue, due to its good cohesiveness and adhesion, there may be a problem of adhesion to the inner wall of the equipment. If it is not scraped off in time before mixing, it will affect the quality of subsequent mixing. The existing solution is to add a rubber strip to the stirring piece to better scrape off the raw materials on the inner wall. However, the softness of the silicone may cause delays and jams with the stirring piece during the mixing process, affecting the mixing efficiency. At the same time, long-term scraping may cause damage to the silicone strip. If the scraping force is insufficient, the adhered raw materials cannot be effectively removed. In order to better scrape off the raw materials adhered to the inner wall of the equipment and stir them to make the mixing more uniform, a mixing equipment for the production of polyurethane potting glue is proposed. Utility Model Content
[0004] The utility model aims at the deficiencies in the prior art and provides a stirring device for producing polyurethane potting glue. When the stirring mechanism controls the external sleeve to rotate relatively in the tank body, a force is applied to the stirring piece, so that the connecting piece arranged at the connecting end of the stirring piece can swing in a small range within the interval of the interval frame, and can be reset by the elastic force of the reset spring arranged in the interval after the swing. During the swinging process, the stirring piece can have a momentary residence time, so that the stirring piece can directly scrape the adhered part of the inner wall of the stirring body, and can effectively remove the adhered raw materials. While improving the scraping efficiency, it is not easy to cause the problem of insufficient scraping force. After removal, it is combined with the raw materials mixed in the stirring body and fully mixed, so as to improve the stirring effect.

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The stirring device for producing polyurethane potting glue of the present application is mainly composed of a stirring machine body 1 and a stirring mechanism 101. The stirring rod of the stirring mechanism 101 is provided with stirring blades, which can extend to the inside of the stirring machine body 1 to stir the raw materials. A plurality of stirring pieces 102 for breaking up the raw materials are arranged at the outer axis of the stirring rod so that the raw materials can be fully mixed. One end of the stirring piece 102 is evenly distributed and installed on the outer wall of the external sleeve 2 through the external sleeve 2, wherein the external sleeve 2 is sleeved to the outside of the stirring mechanism 101 and connected thereto, and the stirring mechanism 101 controls the stirring piece 102 on the external sleeve 2 to rotate, and the outer end surface of the stirring piece 102 is arranged to rotate along the inside of the stirring machine body 1 tank. At this time, a connecting piece 4 is installed at the end of the stirring piece 102 corresponding to the external sleeve 2, and a plurality of connecting pieces 4 that can make the connecting piece 4 movable are installed outside the external sleeve 2. The interval frame 3 is moved, and the connecting piece 4 can move relatively within the interval of the interval frame 3. A reset spring 5 is installed between the external sleeve 2 and the connecting piece 4. When the stirring mechanism 101 controls the external sleeve 2 to rotate relatively in the tank body, it will bring a rotational force to the stirring piece 102, so that the connecting piece 4 set at the connecting end of the stirring piece 102 can swing within the interval of the interval frame 3 in a small range. After swinging, it can be reset by the elastic force of the reset spring 5 set in the interval. During the swinging process, the stirring piece 102 can have a momentary residence time to scrape the adhered part of the inner wall of the stirring machine body 1 to improve the scraping efficiency. At the same time, the scraping method directly using the stirring piece 102 is not prone to the problem of insufficient scraping force, and can effectively remove the adhered raw materials. After removal, they are combined with the raw materials mixed inside the stirring machine body 1 and fully mixed to improve the stirring effect.
[0038] In some embodiments, the method of scraping and stirring at the same time can also avoid the problem that the raw materials adhered to the inner wall of the mixer body 1 cannot be mixed, and the raw materials are carried out when discharging, resulting in uneven mixed raw materials; matching slopes are provided on the interval frame 3 and the connecting member 4, and when the connecting member 4 swings relatively in the inner interval of the interval frame 3, the slope of the connecting member 4 is closely fitted to the slope of the external sleeve 2 to ensure the stability of the upper and lower ends, limit the activity range of the connecting member 4,
