[0031] The driving mechanism 6 is used to provide power to the two rolling assemblies 3 to perform rolling and mixing of the rubber.

[0032] In this embodiment, when it is needed, the rubber to be squeezed is first placed between the two roller assemblies 3, and then the driving mechanism 6 drives the two roller assemblies 3 at the same time to roller-press the rubber. Before use, the power mechanism 5 can be used to provide power to the two adjustment assemblies 4 to adjust the height of the upper roller assembly 3, so as to adjust the distance between the two roller assemblies 3. Through the set driving mechanism 6, the two roller assemblies 3 can still be driven when the distance between the two roller assemblies 3 changes. Compared with the driving structure in the comparative document, the structure is simpler and more reliable, thereby reducing the production and manufacturing costs and the use costs and improving the stability of use.
