Abstract

The invention discloses a high-power drafting assembly used for a ring spinner, comprising a front drafting roller pair with a front roller and a front belt roller, and a rear drafting roller pair with a rear roller and a rear belt roller, wherein, a middle roller and an upper middle roller are arranged between the front drafting roller pair and the rear drafting roller pair, an upper pin is arranged between the upper middle roller and the front belt roller, while a lower pin is arranged between the middle roller and the front roller, an upper apron is sleeved on the upper middle roller and the upper pin, a lower apron is sleeved on the middle roller and the lower pin, the forward setting distance K between the upper pin front edge and the lower pin front edge is at least 3 millimeters, the ratio of the setting distance L from the upper middle roller to the front belt roller and the setting distance S from the roller to the front roller is between 1.1 and 1.6. The high-power drafting assembly can shorten the freestream flow zone length to the utmost extent, extend the control area of the apron, effectively increase the drafting multiple of the drafting assembly and guarantees the quality of the completed filament.

Description

technical field [0001] The present invention relates to a ring spinning frame, in particular to a double apron drafting device for a ring spinning frame. Background technique [0002] The traditional ring spinning frame mostly adopts the double-apron three-roller drafting structure, which includes the front roller pair composed of the front roller and the front top roller, the middle roller pair composed of the middle roller and the middle top roller, and the rear roller and the rear roller. The rear roller pair composed of top rollers. The above-mentioned three-roller pair divides the entire drafting device into two drafting areas, the front and the rear, with the middle roller as the boundary. The rear drafting zone is mainly a simple roller drafting structure, while the front drafting zone generally adopts double apron drafting, and the working faces of the upper and lower aprons respectively placed on the upper and lower pins are in direct contact with the yarn, forming...
