Description

Technical Field

[0001] This utility model belongs to the field of silicone rubber preparation technology, specifically a fully automated batching system for silicone rubber preparation. Background Technology

[0002] Silicone rubber refers to rubber whose main chain is composed of alternating silicon and oxygen atoms, with two organic groups usually attached to each silicon atom. Ordinary silicone rubber mainly consists of siloxane chains containing methyl groups and a small amount of vinyl groups. The introduction of phenyl groups can improve the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can improve its temperature and oil resistance. Silicone rubber has good low-temperature resistance. During the silicone rubber compounding process, the raw materials need to be stirred. According to the patent document with authorization announcement number CN214635935U, entitled "A Compounding Device for Silicone Rubber," several stirring rods are set on the rotating shaft to ensure thorough mixing of the materials during stirring. A dust collection device is installed in the device to solve the dust problem during stirring, reducing the impact on operator health. A dust exhaust pipe is installed in the dust collection device so that the sucked-in dust can return to the mixing drum without affecting the mixing ratio. However, the following drawbacks still exist:

[0003] It mixes ingredients by rotating the stirring rod. However, after prolonged use, ingredients tend to stick to the inner wall of the mixing drum, making it difficult to clean the inside of the mixing drum later. Utility Model Content
