High-speed rewinding machine

Abstract

The invention discloses a high-speed rewinding machine, which comprises a motor, an arc-shaped structure, a gear, rewinding devices and the like, wherein a single rewinding device comprises a winding frame, a groove drum, a U-shaped plate frame, a cylindrical friction roller which is sleeved on a friction roller shaft, and a thread guard consisting of a fairlead and an adjusting post; the groove drum comprises a groove drum body which is made of an aluminum alloy, a groove drum shaft and a transverse reciprocating device with a spinning head; the spinning head is exposed out of one side of the groove drum close to the winding frame; the bottom of the groove drum body is semicircular; the top of the groove drum body is provided with a flat cover plate; the groove drum body is obliquely arranged on a frame flat plate through a groove drum body assembly; the spinning head side of the groove drum faces upward; a direction in which a spool core of a spool is clamped by the winding frame iskept parallel to the traversing direction of the spinning head; and an included angle between the groove drum body cover plate and the horizontal plane is 10-30 degrees. The technical scheme has the advantages of simple structure, reasonable design, low noise, capability of realizing high-speed precise winding and increase in the working efficiency and economic efficiency of a plant.

Description

technical field [0001] The invention relates to the field of textile machinery equipment, in particular to a high-speed rewinding machine. Background technique [0002] Rewinding is the first process of preparation before weaving. Its task is to process the bobbins or skeins from the spinning department into bobbins that meet certain requirements on the winding machine, and provide them for warping, weft winding, knitting, and non-woven fabrics. Weft feeding or bleaching and dyeing of shuttle looms. Rewinding machine is a kind of unwinding yarn from a large spindle and winding it to a yarn gathering cone or bobbin to wind the yarn to form a larger or smaller size yarn bobbin for subsequent The application provides the most practically needed equipment. The bobbin core may be cylindrical, frusto-conical, or otherwise shaped as required by the subsequent application. [0003] The existing rewinding machine generally includes a power device composed of a motor and a conveyor...

AI Technical Summary

Problems solved by technology

[0004] The existing rewinding machines have the following defects in use: 1. The transverse reciprocating motion of the yarn is not separated from the winding motion during use, but the grooved drum is used as a yarn guide, and the yarn drum is driven by friction on the one hand. Circular motion, on the other hand, uses a special groove to guide the yarn to reciprocate laterally, resulting in easy yarn overlap, and the overlapping yarn will cause great trouble to the subsequent unwinding process; 2, or although there is a separation device but the structure The design is unreasonable, and the speeds of the two cannot be controlled separately, or the generation of overlapping and convex edges cannot be effectively prevented, the unwinding performance is not good, and high-speed winding cannot be performed; 3. The design of each component is unreasonable, and the reliability of the operation is poor. Resulting in poor winding forming and unwinding performance; 4. The connection design between the various components is unreasonable, the energy consumption is serious during use, and the winding speed of the bobbin cannot be increased

[0005] Furthermore, when the motor drives the smooth belt and then drives the grooved cylinder to move, the belt pulley is prone to slipping, resulting in the inability to increase the rotational speed, the efficiency of rewinding the cylinder is low, and the running speed is unstable
