Problems solved by technology

If the twist conversion gear is replaced in the head box of the existing spinning machine, due to the limited mechanical structure and the strength of the gear, it can meet up to about 1900 twists / m; if the head box assembly is redesigned, the production cycle will be long and the transformation cost will be high ; If by increasing the pulley transmission ratio between the main shaft and the headstock, such as increasing the large pulley, because there are drafting transmission parts around it, the space is limited; Already the minimum limit number of teeth
Therefore, the above various schemes cannot realize user requirements.

Abstract

The invention relates to a device which can expand the twisting degree scope of a spinning machine. The device comprises a base (1), a bearing seat (2), a main axle (3), a tooth-shaped belt wheel (4), a tooth-shaped belt (5), a small axle (6), a tooth-shaped belt wheel (7), a belt wheel seat (8), a tooth-shaped belt wheel (9), a tooth-shaped belt (10) and a tooth-shaped belt wheel (11). The base (1) is provided with the bearing seat (2), the bearing seat (2) is arranged on a bottom plate of the machine head, the main axle (3) is arranged on the bearing seat (2), the tooth-shaped belt wheel (4) is arranged on the main axle (3) and is connected with the tooth-shaped belt wheel (7) through the tooth-shaped belt (5), the belt wheel seat (8) is disposed on a head wall plate, the small axle (6) is arranged in the belt wheel seat (8), the tooth-shaped belt wheel (7) and the tooth-shaped belt wheel (9) are arranged on the small axle (6), the tooth-shaped belt wheel (9) is connected with the tooth-shaped belt wheel (11) through the tooth-shaped belt (10), and the tooth-shaped belt wheel (11) is arranged on an upper input axle (12) of a lathe head. The device has the function of expanding the twisting degree scope.

Description

technical field [0001] The invention belongs to spinning frames, in particular to a set of devices for expanding the twist range of spinning frames. Background technique: [0002] At present, many users need to expand the twist range of the original spinning frame (1800 twists / m) to about 3000 twists / m if they want to spin fine and extra-fine yarns. If the twist conversion gear is replaced in the head box of the existing spinning machine, due to the limited mechanical structure and the strength of the gear, it can meet up to about 1900 twists / m; if the head box assembly is redesigned, the production cycle will be long and the transformation cost will be high ; If by increasing the pulley transmission ratio between the main shaft and the headstock, such as increasing the large pulley, because there are drafting transmission parts around it, the space is limited; Already the minimum limit number of teeth. Therefore above various schemes all can't realize user's requirement. ...
