[0026] A fixed outer shell 3 is fixedly installed at the midpoint of the lower end face of the mixing tank 1. A second servo motor 17 is embedded inside the fixed outer shell 3. A second drive shaft 15 is fixedly installed at the output end of the second servo motor 17. Three lower stirring blades 8 are provided on the outer surface of the second drive shaft 15. A lower scraper 11 is provided on the outer surface of the second drive shaft 15. A side scraper 16 is provided on the lower end of the outer surface of the second drive shaft 15.
[0027] Specifically, after a cover plate 5 is installed on the upper end face of the mixing tank 1, a protective shell 4 can be fixedly installed on the upper end face of the cover plate 5. After a first servo motor 12 is embedded inside the fixedly installed protective shell 4, the protective shell 4 can provide a certain degree of protection for the first servo motor 12. After a first drive shaft 13 is fixedly installed at the output end of the first servo motor 12, the first drive shaft 13 can be rotated to pass through the midpoint of the upper end face of the cover plate 5. After three upper stirring blades 7 are fitted on the outer surface of the first drive shaft 13 through the cover plate 5, the upper part of the mixing tank 1 can be stirred. At the same time, an upper scraper 10 is fixedly installed on the outer surface of the first drive shaft 13, which can be used to stir the upper part of the mixing tank 1. The upper inner wall of the mixing tank 1 is scraped and cleaned. After the fixed outer shell 3 is fixedly installed on the lower end face of the mixing tank 1, the second servo motor 17 can be embedded inside the fixed outer shell 3. At the same time, the fixed outer shell 3 can protect the second servo motor 17. The output end of the second servo motor 17 is fixedly equipped with a second drive shaft 15. After the second drive shaft 15 is rotated and passed through the interior of the mixing tank 1, a lower stirring blade 8, a lower scraper 11, and a side scraper 16 can be sleeved on the outer surface of the second drive shaft 15. The lower stirring blade 8 can stir the lower end of the interior of the mixing tank 1, while the lower scraper 11 and the side scraper 16 can scrape and clean the lower inner wall of the mixing tank 1.
[0028] Reference Figure 4 The first drive shaft 13 is fixedly installed at the output end of the first servo motor 12, and the first drive shaft 13 rotates through the midpoint of the upper end surface of the cover plate 5.
[0029] Specifically, after the first drive shaft 13 is installed and fixed at the output end of the first servo motor 12, the first servo motor 12 can drive the drive shaft to rotate. At the same time, after the first drive shaft 13 is rotated through the midpoint of the upper end face of the cover plate 5, the first drive shaft 13 can rotate better inside the mixing tank 1.
[0030] Reference Figure 3 and Figure 4 Three upper stirring blades 7 are fixedly sleeved at the midpoint, front end and lower end of the outer surface of the first drive shaft 13, and the upper scraper 10 is fixedly sleeved at the upper end and lower end of the outer surface of the first drive shaft 13, respectively.
[0031] Specifically, by fixing the upper stirring blade 7 at the midpoint, front end, and lower end of the outer surface of the first drive shaft 13, the first drive shaft 13 can better drive the upper stirring blade 7 to rotate at the upper end of the mixing tank 1, mixing the raw materials and additives at the upper end of the mixing tank 1. At the same time, the upper scraper 10 is fixed at the upper and lower ends of the outer surface of the first drive shaft 13. When the first drive shaft 13 rotates, it can also drive the upper scraper 10 to scrape the inner wall of the upper end of the mixing tank 1, which can scrape off the attached raw materials.
[0032] Reference Figure 3 and Figure 5 Three lower stirring blades 8 are fixedly sleeved on the outer surface of the second drive shaft 15, the front end and the lower end of the lower scraper 11 are fixedly sleeved on the front end and the lower end of the outer surface of the second drive shaft 15, and the side scraper 16 is fixedly sleeved on the lower end of the outer surface of the second drive shaft 15.
[0033] Specifically, after the three lower stirring blades 8 are fixedly sleeved on the outer surface of the second drive shaft 15, the rotating second drive shaft 15 can drive the three lower stirring blades 8 to rotate, thereby stirring and mixing the raw materials and additives at the lower end of the mixing tank 1. At the same time, the lower scraper 11 and the side scraper 16 are also fixedly sleeved on the outer surface of the second drive shaft 15. When the second drive shaft 15 rotates, it can also drive the lower scraper 11 and the side scraper 16 to scrape and clean the inner wall at the lower end of the mixing tank 1.
[0034] Reference Figure 3 A fixing plate 14 is fixedly installed at the midpoint inside the mixing tank 1. The lower end of the first drive shaft 13 and the upper end of the second drive shaft 15 are respectively rotatably embedded at the midpoint of the upper and lower end surfaces of the fixing plate 14.
[0035] Specifically, after the fixing plate 14 is fixedly installed inside the mixing tank 1, the first drive shaft 13 and the second drive shaft 15 can be rotatably embedded into the upper and lower end faces of the fixing plate 14, thereby playing an auxiliary role in the rotation of the first drive shaft 13 and the second drive shaft 15 and preventing the first drive shaft 13 and the second drive shaft 15 from deviating when rotating.
[0036] Reference Figure 1 and Figure 3 The cover plate 5 has inlet ports 9 embedded on both sides of its upper surface, and the mixing tank 1 has a discharge pipe 6 embedded on one side of its outer surface near the lower end.
[0037] Specifically, after two feed ports 9 are embedded in the upper end of the cover plate 5, the raw materials and additives can be transported into the interior of the mixing tank 1 at the same time. After a discharge pipe 6 is embedded in the lower end of one side of the mixing tank 1, the mixed raw materials and additives can be discharged.
[0038] Reference Figure 1 and Figure 2 The cover plate 5 is snapped into the upper end face of the mixing tank 1, and the support frame 2 is snapped into the lower end of the outer surface of the mixing tank 1.
[0039] Specifically, after the cover plate 5 is embedded and installed on the upper end of the mixing tank 1, the mixing tank 1 can be sealed, which can better mix the raw materials and additives. After the support frame 2 is snapped on at the lower end of the mixing tank 1, the foaming device can be supported and fixed.
[0040] Working principle: During use, the operator inserts the raw material and additive conveying pipe and the upper end of the cover plate 5 into the feed inlet 9 for connection, thereby conveying the raw materials and additives into the mixing tank 1. After starting the first servo motor 12 and the second servo motor 17, the upper and lower stirring blades 7 and 8 inside the mixing tank 1 rotate. Since the first servo motor 12 and the second servo motor 17 rotate in opposite directions, the rotating upper stirring blades 7 and 8 can better stir and mix the raw materials and additives. The upper cover plate 5, the lower cover plate 5 and the side scraper 16 can scrape off the raw materials adhering to the inner wall of the mixing tank 1, thereby better stirring and mixing the raw materials. After mixing is completed, the mixture can be discharged through the discharge port.
