Spinning frame with guide pulley

Abstract

The invention provides a spinning frame with a guide pulley. The spinning frame comprises a framework, a creel, a thick yarn spindle, the guide pulley, a yarn forming device and a spun yarn bobbin, the creel is mounted on the upper portion of the framework, the thick yarn spindle is fixed onto the creel, thick yarns on the thick yarn spindle are connected with the yarn forming device through the guide pulley, the guide pulley is capable of freely rotating and is positioned in the middle of the thick yarn spindle, the yarn forming device is positioned on the lower portion of the guide pulley, and spun yarns generated by the yarn forming device are connected with the spun yarn bobbin through a guide wire. According to the spinning frame with the guide pulley, the yarns are guided by the pulley structure when the yarns of the thick yarn spindle are coiled out, and the tightness of the spun yarns is more balanced.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a pulley wire spinning frame. Background technique [0002] Yarn is spun from cotton fiber or chemical fiber through a spinning machine, but when the yarn is spun for the first time, the spun yarn is usually a roving, and the density of the roving is not high, which is difficult to meet the requirements of production. Therefore, before production, the semi-finished roving or slivers must be drawn, twisted, and wound into spun yarns by spinning frames for use in the next step of production. However, the current spinning frame usually directly pulls the roving spindle on it, and then performs traction, twisting and winding to form a spun yarn. However, due to the large volume of the roving spindle, the traction mechanism on the spinning frame usually uses a fixed ring body. , so that the variation range of the tension and speed of the roving yarn during outpu...

Problems solved by technology

[0002] Yarn is spun from cotton fiber or chemical fiber through a spinning machine, but when the yarn is spun for the first time, the spun yarn is usually a roving, and the density of the roving is not high, which is difficult to meet the requirements of production. Therefore, before production, it is necessary to use the spinning machine to draft, twist, and wind the semi-finished roving or sliver into spun yarn for the next step of production

However, the current spinning frame usually directly pulls the roving spindle on it, and then performs traction, twisting and winding to form a spun yarn. However, due to the large volume of the roving spindle, the traction mechanism on the spinning frame usually uses a fixed ring body. , so that the tension and speed of the roving yarn vary widely during output, making the quality of the spun yarn not uniform enough, which affects the quality of the next step when the yarn is produced into fabric
