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 for expanding the twist range of a spinning frame. A bearing seat (2) is arranged on the base (1), the bearing seat (2) is arranged on the bottom plate of the headstock, and the main shaft (3) is arranged on the bearing seat (2). The main shaft (3) is provided with a first toothed pulley (4), the first toothed pulley (4) is connected with the second toothed pulley (7) through the first toothed belt (5), and the pulley seat (8) be arranged on the head wallboard, the small shaft (6) is arranged in the pulley seat (8), and the second toothed pulley (7) and the third toothed pulley (9) are all arranged on the small shaft ( 6), the third toothed pulley (9) is connected with the fourth toothed pulley (11) through the second toothed belt (10), and the fourth toothed pulley (11) is set on the input shaft on the head box (12) on. The device has the function of expanding the twist range.

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. ...
