Winding tensioner

Abstract

The invention discloses a winding tensioner. The winding tensioner comprises a reversing device, a tensioning system and a guiding device; the tensioning system comprises a permanent damper and a tension wheel, the permanent damper is fixedly mounted on a corresponding mounting bracket, the tension wheel is mounted on a central shaft of the permanent damper, and an axial direction of the tension wheel is vertical to a travelling direction of a glass fiber yarn. The permanent damper has stable slip and torque and is free from the slip; and the torsion is unchanged when the permanent damper is static or rotated; therefore, the torsion is constant when the winding tensioner achieves the top rotating speed from the lowest speed so as to guarantee the quality of the product obtained by windingthe glass fiber yarn; and meanwhile, since the tension wheel enables the friction between the glass fiber yarn and the tension wheel to be the static friction, the loss to the glass fiber yarn in thetension system can be reduced to the lowest degree. The winding tensioner provided by the invention can reduce the loss to the glass fiber yarn of the glass fiber in the tension system, and improve the quality of the product obtained by winding the glass fiber yarn.

Description

technical field [0001] The invention relates to the technical field of glass fiber processing machinery and equipment, in particular to a winding tensioner. Background technique [0002] At present, in the winding process of the glass fiber industry, the winding tensioner used in the winding machine generally uses a fixed tension rod to form a fixed tension system to adjust the tension of the glass fiber yarn during the winding process, so that the product The package volume density and other physical indicators reach a reasonable range. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a winding tensioner using a fixed tension bar in the prior art. [0004] figure 1 Among them, 1 winder body; 2 guide rod; 3 fixed tension rod mounting bracket; 4 fixed tension rod; 5 reversing rod; 6 glass fiber yarn; 7 glass fiber yarn ball. [0005] During the winding process of the glass fiber, the glass fiber yarn 6 enters the fixed tension system f...

Problems solved by technology

[0009] Therefore, in the winding tensioner provided by the above-mentioned technical solution, the tension system provided by the tension system to the glass fiber yarn is not constant, which will cause the volume density of the glass fiber yarn winding to become smaller during start-up and shutdown, which is different from normal speed. The volume density of the glass fiber yarn is inconsistent, which will cause the product to be prone to quality accidents such as deformation, yarn bursting, and yarn collapse during storage, transportation and use; therefore, using the winding tensioner provided in the above technical solution, glass fiber yarn winding There are also serious defects in the quality of the final product
