Double twister

Abstract

The invention relates to a double twister, which is suitable for double twisting procedure of pure cotton and blended yarn of cotton, wool, polyester and the like in textile industry. The double twister comprises a double twisting mechanism, a traction mechanism, a transversal moving mechanism and a winding mechanism, wherein the double twisting mechanism comprises a spindle component (3), a nylon belt (12) and two nylon belt driving motors (1), wherein the transversal moving mechanism comprises a yarn guiding device (9), a transversal moving device and a transversal moving motor (5); the traction mechanism comprises a traction driving wheel (10), a traction rubber pressing wheel (11) and a traction motor (4); the traction driving wheel (10) and the traction rubber pressing wheel (11) form compression driving; the traction driving wheel (10) is connected with the traction motor (4); the winding mechanism comprises a winding driving wheel (8), a yarn winding barrel (7) and a winding motor (6); and the winding driving wheel (8) is connected with the winding motor (6). The traction driving wheel and the winding driving wheel are respectively driven by the independent motors, the traction motor and the winding motor are combined with electrical control to conveniently adjust the winding density, the yarn running speed is not affected, and the nonuniform twisting index is not affected.

Problems solved by technology

[0003] The winding drive wheel is connected to the traction drive through a geared belt motor. The winding line speed is the running speed of the yarn, and the winding line speed is transmitted through the friction of the winding drive wheel, and there will be slipping; this transmission mode traction speed It is consistent with the winding line speed and cannot be adjusted; it also affects the running speed of the yarn and easily causes instability of the uneven twist index
