Spinning machine servo drive winding transversing gear

Abstract

The invention relates to a spinning machine servo drive winding transversing gear, belongs to the technical field of textile machinery parts, and overcomes the defects that the existing yarn guide transversing gears are complex in structure and cannot satisfy the requirements of multi-variety spinning. A yarn guide rod transversing drive mechanism on each set of yarn guide rods drives the yarn guide rods to horizontally reciprocate left and right. Each yarn guide rod transversing drive mechanism comprises a base plate, a servo motor, a transmission mechanism, a sensing mechanism and an energy accumulation mechanism. The transmission mechanism comprises a slider part, a slide rod, a synchronous belt and two synchronous belt pulleys. The energy accumulation mechanism comprises two spiral springs and one spring guide rod. The axial direction of the spring guide rod is same with that of the slide rod. The spring guide rod and the slide rod are fixedly mounted on the base plate. One spiral spring is sleeved at each of the two ends of the spring guide rod. The slider part is located between the adjacent ends of the two spiral springs. The distance between the adjacent ends of the two spiral springs is smaller than the transversing travel of each guide rod. The sensing mechanism comprises two sensing switches. The sensing mechanism senses the slider part through the sensing switches and feeds back a signal to a control system.

Description

technical field [0001] The invention belongs to the technical field of textile machinery components, and in particular relates to a servo-driven winding and traversing device for a spinning machine. Background technique [0002] The rotor spinning machine is composed of a plurality of adjacent spinning spindles of the same type. The spinning spindles are respectively arranged on both sides of the frame. Thread traversing realizes cross-winding of yarn onto the bobbin, and the winding cross angle and winding density can be changed by controlling the winding speed and the traversing speed of the yarn guide rod. The yarn guide rods on each side are connected together, and the lateral reciprocating movement of the yarn guide rod is realized by connecting the yarn guide traverse driving mechanism at the head end of the yarn guide rod. The existing yarn guiding traverse driving mechanism generally adopts a grooved cylindrical cam connected with the ends of the yarn guiding rods ...
