[0002] Air-jet spinning is a new spinning technology that uses air flow to condense and twist fibers in a high-speed rotating spinning cup to output yarn. It does not require a spindle and mainly relies on multiple components such as the combing roller, spinning cup, and false twist device. The combing roller is used to grab and comb the fed cotton sliver fibers, and the centrifugal force generated by its high-speed rotation can throw out the grabbed fibers.

It can be achieved by setting a conveyor belt, a servo motor, a first turntable, a second turntable, a belt, a threaded rod, a moving block and a protective plate. The setting of the protective plate is used to meet the effect of protecting both sides of the conveyor belt, and the rotation of the first turntable and the second turntable is used to meet the effect of adjusting different distances of the protective plate, avoiding inconvenience in use due to unchanged protection, which is beneficial to improving the safety during the doffing transportation process and at the same time beneficial to improving the working efficiency of the air-jet spinning doffing belt.

[0004] However, the above technical solution has the following defects: when the paper tube falls on the inclined buffer plate in the above-mentioned air-spinning doffing belt, it is easy to roll to the edge of the buffer plate and fall out. When the paper tube rolls onto the conveyor belt, it will roll and collide with each other at will, causing the yarn on the paper tube to be entangled or scattered. Utility Model Content
