[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce a large deformation under a small external force, and can return to its original shape after the external force is removed.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The uniform drying device for aerospace-specific rubber proposed by the utility model, when in use, first places rubber particles on the conveyor belt for transmission, and then first passes through the first group of drying devices to dry the rubber. When the dried rubber particles continue to be transmitted by the conveyor belt, the driving motor can be started to rotate the support shaft, so that the rotation of the support shaft can be used to make the protrusion knock on the inner surface of the conveyor belt, and the rubber particles on the surface of the conveyor belt can be bounced by the knocking action.

After drying, the rubber particles continue to be transmitted by the conveyor belt 2, and the drive motor 8 can be started to rotate the support shaft 5, so that the rotation of the support shaft 5 can be used to make the protrusion 7 knock on the inner surface of the conveyor belt 2. The knocking effect can make the rubber particles on the surface of the conveyor belt 2 bounce up. After the rubber particles bounce up, the second group of drying equipment 3 is used to dry the rubber particles. The elastic effect of the rubber can prevent the rubber from always adhering to the surface of the conveyor belt 2, thereby improving the uniformity of the rubber drying.

[0026] When in use, the driving motor 8 can be started to rotate the support shaft 5 in cooperation with the bearing 12, and then the positioning ring 6 can also be rotated, so that the surface of the conveyor belt 2 can be knocked by the protrusion 7 arranged on the surface of the positioning ring 6.

[0029] When in use, the buffer plate 10 can be used in conjunction with the elastic plate 11 to block the elastic rubber particles on the one hand to prevent the rubber particles from splashing to places outside the conveyor belt 2, and on the other hand, the elasticity of the elastic plate 11 can be used to reduce the knocking sound of the rubber particles on the buffer plate 10 to avoid causing a large noise problem.

[0030] In actual use, the rubber particles are first placed on the conveyor belt 2 for transmission, and then the rubber is dried by the first group of drying equipment 3. After drying, the rubber particles continue to be transmitted by the conveyor belt 2, and the driving motor 8 can be started to rotate the support shaft 5, so that the rotation of the support shaft 5 can be used to make the protrusion 7 knock on the inner surface of the conveyor belt 2, and the rubber particles on the surface of the conveyor belt 2 can be bounced by the knocking. After the rubber particles bounce, the second group of drying equipment 3 is used to dry the rubber particles. The elastic effect of the rubber can prevent the rubber from always adhering to the surface of the conveyor belt 2, which can improve the uniformity of the rubber drying. This avoids the traditional drying equipment 3 mainly using the air outlet to blow and dry the rubber on the surface of the conveyor belt 2 when in use, which may cause the drying of the rubber particle raw material to be relatively uneven, and it is not convenient to dry the bottom of the rubber particles, thereby affecting the use.
