[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a TPE material production internal mixer, including a mixing chamber body 1, three mixing shafts 2 rotatably fitted inside the mixing chamber body 1, a drive structure installed on one side of the mixing chamber body 1, the drive structure corresponding to the mixing shafts 2, a storage box 10 fixed on the mixing chamber body 1, the storage box 10 being connected to the mixing chamber body 1, a feeding roller 12 and a grinding roller 14 rotatably fitted inside the storage box 10, and a sealing sleeve 11 fixed inside the storage box 10, the sealing sleeve 11 corresponding to the feeding roller 12.

[0021] In this embodiment, the drive structure includes a first motor 3, which is fixed to one side of the mixing chamber body 1. The output end of the first motor 3 is fixedly connected to one of the mixing shafts 2. A first gear 5 is fixed to the output end of the first motor 3, and a second gear 6 is fixed to the end of the mixing shaft 2 away from the first motor 3. The second gear 6 meshes with the first gear 5.

[0022] Specifically, starting the first motor 3 causes the first motor 3 to drive the first gear 5 and one of the mixing shafts 2 to rotate. At the same time, the first gear 5 meshes with the second gear 6 and rotates, which causes the other two mixing shafts 2 to rotate, thus enabling material mixing.

[0023] The mixing chamber body 1 has a feed inlet 9, which is connected to the storage box 10. A second motor 4 is fixed on one side of the storage box 10. The output end of the second motor 4 is fixedly connected to the feeding roller 12. A third gear 7 is fixed at the end of the feeding roller 12, and a fourth gear 8 is fixed at the end of the grinding roller 14. The third gear 7 and the fourth gear 8 mesh. The feeding roller 12 is located on the inner side of the sealing sleeve 11. Two grooves 13 are opened on the feeding roller 12. The periphery of the grinding roller 14 has a rough surface structure. The grinding roller 14 is in contact with the box wall of the storage box 10.

[0024] Specifically, the TPE material raw material is poured into the storage box 10, and then the second motor 4 is started, which drives the feeding roller 12 to rotate. At the same time, the feeding roller 12 drives the grinding roller 14 to rotate through the third gear 7 and the fourth gear 8, so that the raw material enters the groove 13. As the feeding roller 12 rotates, it falls above the grinding roller 14, is ground by the grinding roller 14, and falls into the mixing chamber body 1. During the feeding process, the sealing sleeve 11 and the feeding roller 12 are always in a sealed state, which can ensure the mixing effect.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
