Description

Precompression type yarn automatic packing machine Technical Field The application relates to the technical field of textile yarns, in particular to a precompressed yarn automatic packing machine. Background The precompression type automatic yarn packer is special equipment for high-density and regular automatic packing of finished yarn (mainly cheese and hank yarn) in finishing process of textile industry, and is characterized in that a two-stage process of precompression-final-pressure bundling is adopted, so that the problems of fluffy yarn package, large volume, irregular shape and the like caused by a traditional packing mode are solved, and the precompression type automatic yarn packer is key equipment for realizing automation, standardization and logistics high efficiency. At present, the textile cone yarns are generally precompressed in a compression and abutting mode during precompression, and a certain amount of fluffy space exists during the abutting and compression, so that the space is occupied during packaging and transportation, and the precompression efficiency is poor.
