[0050] Embodiment 1:

[0051] As attached Figure 1 To Attachment Figure 6 As shown:

[0052] The utility model provides a sealing structure of a raw material mixer, comprising a base 1;

[0053] A mixing box 2, the mixing box 2 is fixedly connected to the base 1;

[0054] A mixing motor 3, which is fixedly connected to the left side of the mixing box 2;

[0055] A stirring and mixing box 4, wherein the stirring and mixing box 4 is fixedly connected to the mixing box 2;

[0056] A stirring motor 5, the stirring motor 5 is fixedly connected to the stirring mixing box 4;

[0057] A first feeding port 6, which is fixedly connected to the stirring and mixing box 4;

[0061] A first sealing cover 601, which is hingedly connected to the top rear side of the first feeding port 6;

[0062] The sealing ring 602 is fixedly connected under the first sealing cover 601. When the first feeding port 6 is not in use, the first sealing cover 601 is closed to prevent the pungent gas from being emitted from the first feeding port 6. The sealing ring 602 can ensure better sealing.

[0063] Wherein, the first sealing component also includes:

[0064] A transmission box 8, which is fixedly connected to the first sealing cover 601;

[0065] A first rack 9, the first rack 9 is slidably connected to the inside of the transmission box 8;

[0066] A pull ring 901, the pull ring 901 is fixedly connected to the right side of the first rack 9;

[0067] A first transmission shaft 10, the first transmission shaft 10 is rotatably connected to the inside of the transmission box 8;

[0068] The first gear 1001 is coaxially fixedly connected to the outside of the first transmission shaft 10, and the first gear 1001 is meshed with the first rack 9. The effect of this is to pull the pull ring 901 to the right, and the gear-rack transmission mechanism formed by the meshing of the first gear 1001 and the first rack 9 drives the first transmission shaft 10 to rotate.

[0069] Wherein, the first sealing component also includes:

[0070] A connecting member 1002, the connecting member 1002 is fixedly connected to the lower side of the first transmission shaft 10;

[0071] The rubber block 11 includes two rubber blocks 11, which are respectively fixedly connected to the left and right sides of the connecting piece 1002. The two rubber blocks 11 are in contact with the inner wall of the first feeding port 6. The first transmission shaft 10 drives the connecting piece 1002 to rotate, so that the additives contaminated on the inner wall of the first feeding port 6 are scraped off by the two rubber blocks 11.

[0073] The spiral spring 12, the inner end of the spiral spring 12 is fixedly connected to the top of the first transmission shaft 10, and the outer end of the spiral spring 12 is fixedly connected to the inside of the transmission box 8. The effect is that when the pull ring 901 is pulled to the right, the spiral spring 12 is tightened, and when the pull ring 901 is released, the spiral spring 12 returns to its original state, thereby driving the first transmission shaft 10 to rotate in the opposite direction, bringing the pull ring 901 and the first rack 9 back to their original positions, and also causing the connecting piece 1002 to rotate in the opposite direction, and scraping the inner wall of the first feeding port 6 in the opposite direction again through the two rubber blocks 11.

[0074] The specific usage and function of this embodiment are as follows:

[0075] During the rubber mixing process, when additives need to be added, the first sealing cover 601 is opened and the additives are added through the first feeding port 6. After the additives are added, the first sealing cover 601 is immediately closed. The sealing ring 602 can ensure that the first sealing cover 601 has better sealing performance and reduce the leakage of pungent odor during rubber processing. After closing the first sealing cover 601, the pull ring 901 is pulled to the right, and the gear rack transmission mechanism formed by the meshing of the first gear 1001 and the first rack 9 drives the first transmission shaft 10 to rotate, and the first transmission shaft 10 drives the connecting member 1002 to rotate, so that the additives stained on the inner wall of the first feeding port 6 are scraped off by the two rubber blocks 11, and the pull ring 901 is released. The volute spring 12 returns to its original state, thereby driving the first transmission shaft 10 to rotate in the opposite direction, bringing the pull ring 901 and the first rack 9 back to their original positions, and also causing the connecting member 1002 to rotate in the opposite direction, and the inner wall of the first feeding port 6 is scraped again in the opposite direction by the two rubber blocks 11, so as to ensure that the additives will not be stained on the inner wall of the first feeding port 6.

[0077] Based on the first embodiment, as shown in the attached Figure 1 To Attachment Figure 6 As shown, a second sealing component is also included, and the second sealing component is arranged on and inside the second feeding port 7.

[0078] Wherein, the second sealing component includes:

[0079] A second sealing cover 701, which is slidably connected to the top of the second feeding port 7;

[0080] A first magnet 13, the first magnet 13 is fixedly connected to the front of the top of the second feeding port 7;

[0081] The second magnet 14 is fixedly connected to the top of the second sealing cover 701, so that the first magnet 13 and the second magnet 14 are adsorbed together to prevent the second sealing cover 701 from shifting and to prevent the smell generated by the rubber during the mixing process from being emitted from the second feeding port 7.

[0082] Wherein, the second sealing component also includes:

[0083] A rotating door 15, wherein two rotating doors 15 are provided, and the two rotating doors 15 are discretely hingedly connected to the inside of the second feeding port 7;

[0084] Support springs 16, two groups of support springs 16 are provided, and each group of support springs 16 is provided with two pieces. The tops of the two groups of support springs 16 are respectively fixedly connected to the bottom of the two rotating doors 15, and the bottoms of the two groups of support springs 16 are dispersedly fixedly connected to the inside of the second feeding port 7. The effect brought about is that when the two groups of support springs 16 are in a natural state, the gap between the two rotating doors 15 is extremely small. When the rubber raw materials enter from the second feeding port 7, the two rotating doors 15 open downward under the action of gravity. After the rubber raw materials fall, the two rotating doors 15 quickly return to their original positions under the action of the two groups of support springs 16, thereby minimizing the leakage of pungent odors.

[0085] The specific usage and function of this embodiment are as follows:

[0086] The basic raw material for producing rubber, raw rubber, is fed into the second feeding port 7. First, the second sealing cover 701 is pushed backward, and then the raw rubber is directly fed into the second feeding port 7. Under the action of gravity, the two rotating doors 15 open downward. After the rubber raw material falls, the two rotating doors 15 quickly return to their original positions under the action of two sets of supporting springs 16, so as to minimize the opening time of the second feeding port 7. After the raw rubber is fed, the second feeding port 7 is pulled back, and the first magnet 13 and the second magnet 14 are adsorbed together to prevent the vibration generated during the stirring of the rubber raw material from causing the second sealing cover 701 to shift, thereby reducing the emission of pungent odor.
