Description

Technical Field

[0001] The utility model relates to the field of textile machinery and equipment, in particular to a disposable anti-static yarn support roller for a warping machine. Background Art

[0002] Some problems that exist in the operation of the yarn support rollers of the current sizing machines and disposable warping machines are summarized as follows: The purpose of the disposable warping machine is to form the warp in one go. In order to facilitate the weaving process after the yarn is wound, it is necessary to ensure that the loom head is able to withstand the tension required for unwinding of the loom, so the loom forming needs to achieve sufficient winding density.

[0003] Currently, achieving yarn winding density can only be achieved by using a winding motor with sufficient torque. However, differences in tension between yarns result in uneven yarn surfaces. The best solution to achieve this while also further increasing winding density is to use a yarn support roller for secondary extrusion. However, during the pressing process, friction between the roller surface and the yarn generates a large amount of static electricity, a phenomenon particularly pronounced in yarns such as polyester and glass fiber. If static electricity has nowhere to be released, it can lead to a bundling phenomenon, resulting in the yarn being scrapped. At the same time, high levels of static electricity can seriously affect manufacturing efficiency. Therefore, most glass fiber warping machines have removed the yarn support roller structure to avoid static electricity generation. However, this approach fails to increase winding density and achieve yarn flatness through yarn pressing, severely impacting the weaving process. The same risk exists in the sizing process, and antistatic agents are commonly used in the sizing liquid to reduce the risk of static electricity.

[0004] The yarn support roller generates static electricity because the roller body is made of stainless steel and the two ends are insulating bakelite gaskets. The insulating bakelite gaskets are used to prevent wear on the warp beam aluminum disk. The static electricity generated by the friction between the insulating bakelite gasket and the yarn cannot be released, causing the yarn support roller to carry a large amount of static electricity, resulting in the bread shaft phenomenon, and the yarn will be scrapped. At the same time, a large amount of static electricity will seriously affect manufacturing efficiency. Utility Model Content

During installation, the ductility of the copper is utilized to hammer the bakelite gasket into the two ends of the yarn supporting roller body, so that the roller body and the gasket are tightly connected without loosening, and a good conductive effect can be achieved. In the warping and sizing processes, static electricity generated by friction between the yarn pressing roller body and the yarn is connected to a winding disk through the copper rod, and then connected to a vehicle body through a disk shaft. A ground wire is provided under the vehicle head to conduct the static electricity into the earth, thereby achieving harmless treatment of static electricity.
