[0026] See also Figure 1-3 As shown, the utility model is a rubber plasticizer blending kettle, comprising a heating cylinder 1 and a cover plate 8 installed on the upper end surface of the heating cylinder 1, and also comprising:

[0027] A feed pipe 6 is sealably connected to the upper end of the outer wall of the heating cylinder 1 and is used to add rubber and plasticizer to the interior of the heating cylinder 1. The feed pipe 6 is provided to add rubber and plasticizer to the interior of the heating cylinder 1, and a heating wire is provided in the inner wall interlayer of the heating cylinder 1 to heat the interior of the heating cylinder 1 to increase the fluidity of the rubber filling oil for subsequent stirring and mixing.

The discharge pipe 4 is provided to discharge the mixed rubber filling oil after the subsequent components are stirred, and the switch valve is provided to control the discharge and closing of the discharge pipe 4;

[0028] The support assembly is circumferentially arranged in the middle of the outer wall of the heating cylinder 1, and is used to support the heating cylinder 1. The support assembly includes a mounting sheet metal 2, a supporting foot 3, and a locking screw 5. The mounting sheet metal 2 is circumferentially fixed in the middle of the outer wall of the heating cylinder 1, and the supporting foot 3 is arranged on the lower end surface of the mounting sheet metal 2, and a threaded hole is arranged on the top of the supporting foot 3. The locking screw 5 penetrates the mounting sheet metal 2 and is threadedly connected to the inside of the threaded hole. By tightening the locking screw 5, the supporting foot 3 can be locked and connected with the mounting sheet metal 2, so that the supporting foot 3 can support the entire heating cylinder 1, so that the heating cylinder 1 can be stably suspended for easy use;

[0029] A stirring assembly is arranged at the center of the interior of the heating cylinder 1, and is used to stir the rubber inside the heating cylinder 1 so as to mix it with the plasticizer. The stirring assembly includes a driving motor 7, a driving gear 9, and a stirring shaft 10. The driving motor 7 is fixed at the center of the upper end surface of the cover plate 8, the driving gear 9 is fixed at the output end of the driving motor 7, and the stirring shaft 10 is fixed at the center of the lower end surface of the driving gear 9, and one end of the stirring shaft 10 extends toward the interior of the heating cylinder 1. The driving motor 7 can drive the driving gear 9 to rotate, and then the driving gear 9 can drive the stirring shaft 10 to rotate, so that multiple groups of raw materials of the rubber filling oil can be stirred and mixed;

[0030] The follower assembly is circumferentially arranged on the lower end surface of the cover plate 8 to improve the stirring efficiency. The follower assembly includes a driven gear 13, a rotating shaft 11, and a toothed stirring blade 12. The driven gear 13 is circumferentially distributed and rotatably connected to the lower end surface of the cover plate 8, and the driven gear 13 is meshed and connected with the driving gear 9. The rotating shaft 11 is fixed at the central position of the lower end surface of the driven gear 13. The toothed stirring blade 12 is linearly distributed and fixed to the outside of the rotating shaft 11, and the outer teeth of the toothed stirring blade 12 are folded up and down in sequence. The folding method can make the toothed stirring blade 12 During the rotation process, stirring is performed more efficiently. Since the driven gear 13 is meshed with the driving gear 9, the driving gear 9 can drive the driven gear 13 to rotate. The toothed stirring blade 12 can rotate in the opposite direction to the stirring shaft 10 along with the rotating shaft 11 under the transmission of the driven gear 13. The mixing of rubber and plasticizer can be accelerated with different stirring directions, and the mixing can be made faster and more uniform. The diameter of the stirring paddle on the outer side of the mixing shaft 10 is smaller than the toothed stirring blade 12, so the stirring paddle does not contact the toothed stirring blade 12, and will not affect the normal operation of the equipment.

[0031] The wall scraping assembly is arranged inside the heating cylinder 1 and is used for scraping off the rubber on the inner wall of the heating cylinder 1. The wall scraping assembly includes a driven gear ring 14, a scraping rod 15, and a toothed stirring piece 16. The driven gear ring 14 is rotatably connected to the central position of the lower end surface of the cover plate 8, and the driven gear ring 14 is meshed with the driven gear 13. The scraping rod 15 is fixed to the lower end surface of the driven gear 13, and the outer wall of the scraping rod 15 is in contact with the inner wall of the heating cylinder 1. The toothed stirring piece 16 is fixed to the inner lower end of the scraping rod 15. When the driven gear 13 rotates, the driven gear ring 14 can be driven to rotate, and then the scraping rod 15 is driven to scrape off the rubber filling oil adhered to the inner wall of the heating cylinder 1, and re-enter the central mixing area inside the heating cylinder 1 to make the stirring and mixing more uniform. At the same time, the toothed stirring piece 16 can rotate with the scraping rod 15, and can mix the rubber from the lower end of the inside of the heating cylinder 1 to improve the mixing efficiency.

[0032] Working principle: First, the feed pipe 6 is sealed and connected to the upper end of the outer wall of the heating cylinder 1, and is used to add multiple groups of raw materials of rubber filling oil into the interior of the heating cylinder 1. The feed pipe 6 is set to add the rubber filling oil to the interior of the heating cylinder 1. The bottom of the heating cylinder 1 is sealed and connected with a discharge pipe 4, and a switch valve is set in the middle of the discharge pipe 4. The set discharge pipe 4 is used to discharge the mixed rubber filling oil after the subsequent components are stirred. The switch valve is used to control the discharge and closing of the discharge pipe 4;

[0033] During mixing, the driving motor 7 can drive the driving gear 9 to rotate, and then the driving gear 9 can drive the stirring shaft 10 to rotate. Since the driven gear 13 is meshed with the driving gear 9, the driving gear 9 can drive the driven gear 13 to rotate. The toothed stirring blade 12 can rotate in the opposite direction to the stirring shaft 10 along with the rotating shaft 11 under the transmission of the driven gear 13. The mixing of multiple groups of raw materials of rubber filling oil can be accelerated with different stirring directions, and the mixing can be faster and more uniform. At the same time, the driven gear 13 can drive the driven gear ring 14 to rotate, and then drive the scraper rod 15 to scrape off the rubber filling oil adhered to the inner wall of the heating cylinder 1, and re-enter the central mixing area inside the heating cylinder 1 to make the stirring and mixing more uniform.
