Description

Technical Field

[0001] The utility model relates to the field of rubber processing, in particular to a raw material circulation crushing device for rubber processing. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a molecular weight that is often large, greater than hundreds of thousands. Rubber is divided into natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or various aspects of life. In synthetic rubber, the rubber raw materials need to be crushed and then polymerized, and a crushing device is needed during the crushing process.

[0003] After searching, the applicant found that a Chinese patent disclosed "a raw material circulation crushing device for rubber processing", and its publication (announcement) number is "CN217943922U". The patent mainly arranges an air connection pipe at the front end of the crushing shell. The air connection pipe, the first ventilation pipe, the second ventilation pipe and the connecting pipe are a whole. One end of the first ventilation pipe passes through the protective plate and is located inside the crushing chamber. One end of the second ventilation pipe is located inside the feeding channel. The first ventilation pipe and the second ventilation pipe are both hoses. The air connection pipe is connected to an external air pump, and air is blown into the crushing chamber and the feeding channel respectively by the first ventilation pipe and the second ventilation pipe to avoid large particles of raw materials blocking the feeding port of the feeding channel, and to prevent excessive raw materials from falling and blocking the feeding channel, thereby improving the convenience of feeding. In addition, the air outlet of the second ventilation pipe is downward, and there will be no raw materials entering and blocking it, ensuring normal use.

However, when the crushing is incomplete and circular crushing is required, the above-mentioned device can only release the material first and then pour it into the crusher for circular crushing, which increases the manual workload and reduces the rubber output in disguise.
