Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Please refer to Figures 1-5 , the utility model provides technical scheme: a polyurethane adhesive stirring equipment, include, rotating frame 1.

[0028] As Figure 1 shown, in certain embodiments, the rotating frame 1 is rotationally connected with support frame 2, the inside fixedly connected with stirring assembly 3 of support frame 2, the upper portion of stirring assembly 3 is provided with end cover 4, and the end of stirring assembly 3 away from end cover 4 is fixedly connected with power assembly 5.

[0029] As Figures 2-4 shown, in certain embodiments, the stirring assembly 3 includes stirring barrel 301, shaft sleeve 302, stirring shaft 303, dispersion disc 304, stirring blade 305 and rotating shaft 306, wherein:

[0030] The mixing tank 301 has a cylindrical structure, with one end open and the other end forming a frustum. The larger diameter end of the frustum is fixed to the cylindrical structure. This frustum structure effectively prevents dead zones during mixing. The mixing tank 301 is used to contain and mix polyurethane adhesive. A rotating hole is provided in the frustum portion of the mixing tank 301. A bushing 302 is fixedly connected inside the rotating hole. A rotating shaft 306 is rotatably connected inside the bushing 302. The rotating shaft 306 is hollow and a mixing shaft 303 is rotatably connected inside it. A portion of the mixing shaft 303 is located inside the mixing tank 301, while the other portion is exposed outside the mixing tank 301 through the rotating hole. The portion of the mixing shaft 303 located outside the mixing tank 301 is fixedly connected to the power assembly 5.

[0031] The surface of the stirring shaft 303 is fixedly connected to the dispersion disk 304. The dispersion disk 304 is used to uniformly disperse the polyurethane adhesive in the mixing tank 301. The dispersion disk 304 is provided with an exchange hole for the flow of polyurethane adhesive. The dispersion disk 304 is located in the cylindrical structure of the mixing tank 301. The stirring shaft 303 located below the dispersion disk 304 is fixedly connected to the stirring blade 305. The stirring blade 305 is located inside the frustum structure of the mixing tank 301 and is used to allow the polyurethane adhesive to settle.

[0032] like Figures 2-4 As shown, in some embodiments, the stirring assembly 3 further includes a scraper 307, the lower part of which is fixedly connected to the rotating shaft 306. The scraper 307 contacts the inner wall of the stirring tank 301 and is used to remove adhesive adhering to the inside of the stirring tank 301 during the stirring process.

[0033] like Figure 3 and Figure 5 As shown, in some embodiments, the support frame 2 body is a disc structure, and a connecting hole is opened at the center of the support frame 2. The connecting hole is fixedly connected to the bushing 302. Two support columns are provided on the support frame 2. The support columns are respectively located on both sides of the disc structure. The two support columns are fixedly connected to the outer wall of the mixing tank 301. Each support column is provided with a rotating hole, which is used to rotate and connect with the rotating frame 1.

[0034] After mixing is complete, the support frame 2 is rotated, which drives the mixing tank 301 to rotate, so that the polyurethane adhesive in the mixing tank 301 can flow out from the top.

[0035] like Figure 3 and Figure 4 As shown, in some embodiments, the power assembly 5 includes a protective frame 501 and a motor 502. The protective frame 501 is fixedly connected to the support frame 2. The protective frame 501 includes the connection hole and is located inside the protective frame 501. The motor 502 is fixedly connected to the protective frame 501. The motor 502 includes a motor output end, which is fixedly connected to the stirring shaft 303.

[0036] The power assembly 5 further includes a secondary bevel gear 503, a primary bevel gear 504, and a second motor 505. The secondary bevel gear 503 is located inside the protective frame 501 and is fixedly connected to the rotating shaft 306. The secondary bevel gear 503 meshes with the primary bevel gear 504. The primary bevel gear 504 is fixedly connected to the second motor 505. The second motor 505 is located outside the protective frame 501 and is fixedly connected to the support frame 2. The second motor 505 includes a second motor output end, which passes through the protective frame 501 and is fixedly connected to the primary bevel gear 504.

[0037] By activating motor 502, the stirring shaft 303 rotates, which in turn drives the stirring blades 305 and the dispersing disc 304 to rotate, achieving uniform mixing of the polyurethane adhesive. Simultaneously, by activating motor 505, the primary bevel gear 504 and the secondary bevel gear 503 mesh and rotate. The secondary bevel gear 503 drives the rotating shaft 306 to rotate, which in turn causes the scraper 307 to rotate along the inner wall of the mixing tank 301, effectively removing residual adhesive and ensuring the cleanliness of the inner wall of the mixing tank 301. When the rotation direction of the rotating shaft 306 is controlled to be opposite to the rotation direction of the stirring shaft 303, the relative movement between the dispersing disc 304 and the scraper 307 is driven, which significantly enhances the shear force on the material. This shear force helps to break up agglomerates in the material and promotes finer mixing.

[0038] like Figure 2 As shown, in some embodiments, the end cap 4 is used to seal the top opening of the mixing tank 301 to prevent the adhesive from overflowing during mixing. The end cap 4 is provided with a feeding port, which is used to add or pour polyurethane adhesive raw materials into the mixing tank 301.

[0039] Working principle: Raw materials are added to the mixing tank 301 through the feeding port of the end cap 4. By starting the first motor 502, the first motor 502 drives the stirring shaft 303 to rotate, which in turn drives the stirring blades 305 and the dispersing disc 304 to rotate, thereby achieving uniform mixing of the polyurethane adhesive. At the same time, by starting the second motor 505, the second motor 505 drives the first-stage bevel gear 504 and the second-stage bevel gear 503 to mesh and rotate. The second-stage bevel gear 503 drives the rotating shaft 306 to rotate, thereby causing the scraper 307 to rotate along the inner wall of the mixing tank 301, effectively removing residual adhesive and ensuring the cleanliness of the inner wall of the mixing tank 301. When the rotation direction of the rotating shaft 306 is controlled to be opposite to the rotation direction of the stirring shaft 303, the relative movement between the dispersing disc 304 and the scraper 307 will significantly enhance the shear force on the material. This shear force helps to break up agglomerates in the material and promotes finer mixing.

[0040] After mixing is complete, the support frame 2 is rotated, which drives the mixing tank 301 to rotate, so that the polyurethane adhesive in the mixing tank 301 can flow out from the feeding port of the end cap 4.
