The sealing component includes a valve plate 12 that is movably connected to the inner cavity of the discharge pipe 4 and a drive component 10. The valve plate 12 is driven by the drive component 10, which can be a servo motor. The drive component 10 is connected to the discharge pipe 4. With the setting of the drive component 10, the drive component 10 can drive the valve plate 12 to rotate when it is working. When the valve plate 12 is in a horizontal state, the valve plate 12 can block the discharge pipe 4, which facilitates the use of the equipment. The valve plate 12 is adapted to the discharge port of the discharge pipe 4. An electric telescopic rod 14 is provided in the middle of the valve plate 12. The output shaft of the electric telescopic rod 14 is connected to a sealing plate 13. The sealing plate 13 is adapted to the feed inlet of the discharge pipe 4. The outer diameter of the sealing plate 13 is smaller than the outer diameter of the valve plate 12. By setting the sealing plate 13, the extension and retraction of the electric telescopic rod 14 can change the position of the sealing plate 13. When the valve plate 12 needs to be opened or closed, the electric telescopic rod 14 retracts until the sealing plate 13 contacts the valve plate 12, so that the drive assembly 10 can drive the valve plate 12 to rotate. When the equipment is in use, when the valve plate 12 is in a horizontal state, the electric telescopic rod 14 extends and drives the sealing plate 13 to move upward until the top of the sealing plate 13 is flush with the bottom of the inner cavity of the equipment body 1, so as to facilitate the mixing of raw materials.

[0024] A stirring assembly is provided in the middle of the inner cavity of the device body 1.

The electric telescopic rod 26 is connected to the top end of the inner cavity of the active rotating tube 5. The output shaft end of the electric telescopic rod 26 is fixedly connected to the top of the stirring shaft 11. When the active rotating tube 5 rotates, the electric telescopic rod 26 can drive the stirring shaft 11 to rotate. When the electric telescopic rod 26 extends or retracts, the position of the stirring shaft 11 in the vertical direction can change.

[0026] The stirring shaft 11 has a hollow structure. Rotating shafts 18 are staggered on the shaft wall of the stirring shaft 11. Rotating shafts 18 are movably connected to the stirring shaft 11.

The transmission gear 24 is connected to the end of the rotating shaft 18 away from the stirring blade 19. Through the setting of the transmission structure, the extension and retraction of the electric telescopic rod 15 can change the position of the lifting rod 16. When the lifting rod 16 moves, it can drive the toothed plate 17 connected to it to move. When the toothed plate 17 moves, it drives the transmission gear 24 meshing with it to rotate. The transmission gear 24 drives the rotating shaft 18 fixedly connected to it to rotate. A stirring blade 19 is fixed at the end of the rotating shaft 18 away from the transmission structure. When the rotating shaft 18 rotates, it drives the stirring blade 19 connected to it to rotate. The position of the stirring blade 19 can be changed, which facilitates the cleaning of the stirring blade 19. In addition, when the stirring assembly is in use, the stirring range of the stirring blade 19 can be changed, which facilitates the mixing of raw materials.

[0027] The bottom end of the inner cavity of the stirring shaft 11 is connected to a lower scraper 22 via a rotating shaft 20. The rotating shaft 20 is movably connected to the stirring shaft 11. A servo motor 23 is fixedly connected to the bottom end of the inner cavity of the stirring shaft 11. The end of the output shaft of the servo motor 23 is connected to the end of the rotating shaft 20 away from the lower scraper 22. When the servo motor 23 rotates, it can drive the rotating shaft 20 connected to it to rotate. The rotating shaft 20 drives the lower scraper 22 connected to it to rotate, which facilitates the cleaning of the lower scraper 22. When the equipment is in use, the bottom of the lower scraper 22 contacts the bottom of the inner cavity of the equipment body 1. The lower scraper 22 can scrape off the raw materials adhering to the bottom of the inner cavity of the equipment body 1, which facilitates the mixing of the raw materials.

A side scraper 26 is fixed to one side of the inner wall of the rotating ring 25, and the side scraper 26 contacts the inner wall of the equipment body 1. The other end of the lower scraper 22 contacts the side scraper 26. An electromagnet 21 is provided in the middle of the other end of the lower scraper 22. When the electromagnet 21 is energized, it is magnetically attracted to the side scraper 26. Because of the electromagnet 21, when energized, the lower scraper 22 rotates, which drives the side scraper 26 to rotate. The side scraper 26 can scrape off the raw material adhering to the inner wall of the equipment body 1. When the electromagnet 21 is de-energized, the rotation of the lower scraper 22 allows it to separate from the side scraper 26, facilitating cleaning of the lower scraper 22. The electromagnet 21 can be a DX6026 model.

[0030] In summary: When using this raw material mixing equipment for polyester resin polymerization, the end of the lower scraper 22 furthest from the stirring shaft 11 is in contact with the side scraper 26, and the electromagnet 21 is energized. The raw material for polyester resin polymerization is injected into the inner cavity of the equipment body 1 through the feed pipe 2. The drive assembly 2 7 drives the stirring shaft 11 to rotate, which in turn drives the stirring blade 19 and the lower scraper 22 to rotate. The lower scraper 22 drives the side scraper 26 to rotate via the electromagnet 21. When the stirring blade 19 rotates, it agitates the raw material, ensuring uniform mixing. Both the lower scraper 22 and the side scraper 26... The rotation can scrape off the raw materials adhering to the inner wall of the equipment body 1, facilitating the mixing of raw materials. During the mixing process, the electric telescopic rod 15 can drive the lifting rod 16 to rise and fall. The lifting rod 16 drives the toothed plate 17 to move. The toothed plate 17 drives the rotating shaft 18 to rotate through the transmission gear 24 meshing with it. The rotating shaft 18 drives the stirring blade 19 to rotate, changing the stirring range of the stirring blade 19 and accelerating the uniform mixing speed of the raw materials. During cleaning, the rotating shaft 18 drives the stirring blade 19 to rotate, reducing the difficulty of cleaning the stirring blade 19 and making it easier for staff to check the cleaning effect of the stirring blade 19.
