Description

A glass fiber doubling and twisting yarn device and a doubling and twisting yarn process

technical field

The invention relates to a glass fiber doubling and twisting yarn device and a doubling and twisting yarn process.

Background technique

Glass fiber is an inorganic non-metallic material with excellent performance. It is widely used as reinforcing material, electrical insulating material and circuit substrate in composite materials due to its good insulation performance, strong heat resistance, good corrosion resistance and high mechanical strength. and other fields of the national economy.

There are two conventional glass fiber parallel twisting process routes, one is for textile-type sizing glass fiber yarn, that is, two sets of primary twisting spindle units (including primary twisting spindle and upper dragon belt mechanism) are respectively arranged on both sides of the machine , each first-twisting spindle is respectively equipped with bobbins wound with glass long fibers; the machine is equipped with winding overfeed rollers, double-twisting spindle units and ring plate mechanisms. When working, the long glass fibers unwound from the bobbins of 2 or 3 primary twisting spindles are guided by multiple guide rings on the guide frame to pass through the aisle and then enter the machine table, and then pass through the winding overfeed roller and into 1 strand, and then twisted by the double-twisting spindle and ring plate mechanism to make glass fiber yarn. The layout structure of the above glass fiber twisting machine requires a field width of up to 7m, which occupies a large space and increases the investment cost of the plant; The air circle of the equipment is too small, and the friction of the porcelain eye is large, so it is easy to cause yarn breakage, which reduces the qualified rate and package volume. The other is the parallel twisting process for reinforced sizing glass fiber yarn, which has the disadvantage of small package volume.

In the above two parallel twisting processes, one or more single yarns in the primary twisting spindle are broken, and the remaining single yarns will continue to be unwound and wound on the double twisting spindle to form a missing strand yarn.
