[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figs. 1 to 3 As shown, this embodiment provides an improved thermoplastic elastomer structure, including a hollow cylinder 1. The radial section of the hollow cylinder 1 has an opening of 54°. The outer wall of the hollow cylinder 1 has uniformly circumferentially distributed outer strip protrusions 2, and the inner wall of the hollow cylinder 1 has uniformly circumferentially distributed inner strip protrusions 3.

[0023] The hollow cylinder 1 has a circular cross-section.

[0024] The ratio of the outer diameter to the inner diameter of the hollow cylinder 1 is 5:3.

[0025] The thickness ratio of the inner strip protrusion 3 to the outer strip protrusion 2 is 1:1-1.5.

[0026] The cross-sections of the inner strip protrusion 3 and the outer strip protrusion 2 are trapezoidal.

[0027] An inner groove 4 is provided between adjacent outer strip protrusions 2. By providing the inner groove 4, the specific surface area is increased to store more additives, making the thermoplastic elastomer and powdered additives mix more evenly.

[0028] Below each inner groove 4 is a material trough 5 with an elliptical cross-section. The material trough 5 communicates with the inner groove 4 through a connecting port 6. The side of the connecting port 6 closest to the inner groove 4 is the narrow side, and the side of the connecting port 6 closest to the material trough 5 is the wide side, with the width of the wide side being twice that of the narrow side. During the mixing process of the thermoplastic elastomer and the powdered additive, the thermoplastic elastomer is subjected to compression from all directions. The narrow side of the connecting port 6 is easily deformed and opened after being compressed, allowing the powdered additive to enter the material trough 5. When the compression disappears, due to the elastic recovery of the thermoplastic elastomer itself, the connecting port 6 will tightly wrap the powdered additive, making it difficult for the powdered additive to separate from the hollow cylinder 1. This improves the bonding between the powdered additive and the thermoplastic elastomer, and increases the mixing degree of the mixture.
