Description

Technical Field

[0001] The utility model relates to the technical field of sisal fiber crushing, and more specifically to a sisal fiber extraction and crushing device. Background Art

[0002] Sisal fiber is derived from the leaves of sisal plants and is extracted through a series of special processes. This fiber is widely used in ropes, fishing nets, carpets, paper and other fields due to its high strength, wear resistance, corrosion resistance and UV resistance. Especially in occasions that need to withstand high strength and harsh environmental conditions, sisal fiber shows its irreplaceable advantages. In addition, with the continuous strengthening of environmental awareness and the popularization of the concept of sustainable development, sisal fiber has been warmly sought after by the market due to its renewable and degradable characteristics.

[0003] Traditional sisal fiber extraction methods mainly include manual vertical beating, hand-pulled scraping machines, semi-automatic scraping machines, and automatic sisal scraping machine production lines. These methods have achieved the extraction of sisal fibers to a certain extent, but in the fiber crushing process, traditional methods often use simple mechanical cutting or grinding methods, resulting in unsatisfactory crushing effects and uneven fiber particle size, which is difficult to meet the needs of high-end applications. In view of this, we propose a sisal fiber extraction and crushing device. Utility Model Content
