Passive compact spinning device and assembly method thereof

Abstract

The invention discloses a passive compact spinning device comprising a rotating hollow cylinder, a negative pressure suction device and a roller sleeve, wherein ventilating grooves are distributed in the working surface of the roller sleeve along the circumferential direction, a ventilating groove is formed in a suction end of the negative pressure suction device from the inner side of an open end of the roller sleeve, an exhaust end of the negative pressure suction device is directly connected with an exhaust pipe, and a negative pressure draught fan in transmission connection with the rotating hollow cylinder is arranged in an air channel of the negative pressure suction device. The assembly method of the device comprises: firstly inserting an insertion piece in the roller sleeve; separately installing an impeller gear and a transition gear in a connecting pin, and sheathing an impeller on a rotating shaft of the impeller gear; embedding a lower slide way on the insertion piece in a predetermined station by aligning to an upper slide way of a front arc-shaped embedding groove; and buckling and pressing a pressing element on the insertion piece to accomplish the installation.

Description

technical field [0001] The invention relates to a spinning device, specifically a passive compact spinning device, and an assembly method of the device, belonging to the new technical field of ring spinning. Background technique [0002] Ring spinning is currently the most important spun yarn production method, which draws and slenders the fed fiber strips with a certain twist, and finally twists them into the required spun yarn. However, due to the existence of the twisting triangle in this technology, on the one hand, the head and tail ends of the side fibers are not easy to be wrapped into the yarn sliver to form hairiness; at the same time, the tension difference between the side fiber and the center fiber is large, and it will not break when stretched. Therefore, the strength of each single fiber cannot be fully utilized to reduce the single yarn strength. Therefore, the research on the twisting triangle of ring spinning has become a hot topic in the textile industry, ...

AI Technical Summary

Problems solved by technology

The currently used airflow compact spinning devices all use negative pressure pipelines to provide concentrated negative pressure, and need to add a negative pressure fan when using it, which increases the energy consumption of the system and the cost of transformation

The currently used mechanical compact spinning device relies on mechanical force to bundle the fibers and does not require additional energy consumption. However, when the mechanical force acts on flexible fiber materials, it is difficult to control the compacting force, which affects the compacting effect. poor adaptability
