Description

Technical Field

[0001] This utility model belongs to the technical field of synthetic rubber pelletizing equipment, specifically relating to a multi-blade pelletizing device with easily adjustable gap. Background Technology

[0002] Synthetic rubber, as an important polymer material, has wide and indispensable applications in many fields. For example, in the automotive manufacturing industry, synthetic rubber is widely used in the manufacture of key components such as tires and seals. Its excellent elasticity, wear resistance, and aging resistance ensure the safety and comfort of vehicle operation. In the electronics and electrical appliance field, it is also frequently used as an insulating material and a shock-absorbing material, playing a crucial role in the stable operation of electronic equipment. As the demand for synthetic rubber continues to rise across various industries, the requirements for related equipment in the synthetic rubber production and processing processes are also increasing.

[0003] In the synthetic rubber production process, after the rubber undergoes a series of chemical reactions such as polymerization to form block or strip-shaped primary products, it is often processed into granular form using relatively crude crushing and cutting methods to facilitate subsequent packaging, transportation, and further processing. During operation, the pelletizing mechanism of the expansion dryer often needs to cut the expanded material particles into shorter pieces according to downstream demands. The existing structure cannot accommodate more cutters; currently, a maximum of six cutters can be installed, and the number of cutters is difficult to adjust. Furthermore, when adjusting the gap between the cutter and the template, the existing structure relies on a key to transmit torque, resulting in a relatively tight fit between the cutter holder, cutter shaft, and key, making adjustment inconvenient.
