Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for wire and cable production, specifically to a stabilizing guide wheel for the core of a wrapped cable. Background Technology

[0002] During cable production, wrapping tape (mica tape, cotton paper tape, aluminum foil, polyester film, etc.) is wrapped around the cable core by rotating the wrapping head to prevent the cable core from loosening. At the same time, it plays a buffering and padding role, protecting the insulation or inner sheath from damage during cable armoring. The wrapping is completed by a wrapping machine.

[0003] During the wrapping process, the core wire is subjected to a radial force of rotation, causing it to be dragged off the axis. The core wire bends at the wrapping cut point, and the wrapping tape becomes uneven and wrinkled. Furthermore, when the tension of the unwinding is small, the displacement of the core wire increases, which can easily cause the core wire to twist and jump, resulting in damage and scrapping of the core wire. Summary of the Invention

[0004] The purpose of this invention is to provide a stabilizing guide wheel for the core of the wrapped cable used in the production of cables, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A stabilizing guide wheel for producing wrapped wire cores of cables includes an end cap 1, a connecting post 5, a seat ring 7, and a guide wheel 11. The end cap 1 has an inner cavity 2 with an opening on the left side. The side wall of the inner cavity 2 is threaded. A wire-passing hole 3 is opened at the center of the end face of the end cap 1 and the center of the seat ring 7. Threaded blind holes 4 are opened on the right end face of the end cap 1 and the left end face of the seat ring 7. The connecting post 5 has threaded heads 6 at both ends. The threaded heads 6 at both ends of the connecting post 5 are connected to the threaded blind holes 4 on the end cap 1 and the seat ring 7, respectively. A strip hole 8 is opened on the seat ring 7. The left end guide wheel shaft 9 of the guide wheel 11 is assembled into the strip hole 8 by a nut 10.

[0007] The guide wheel 11 is rotatably assembled with the guide wheel shaft 9 using a bearing, and the end cap 1 is assembled with the thread of the wrapping shaft using the thread on the side wall of the inner cavity 2.

[0008] There are two strip holes 8, which are symmetrically arranged along one diameter of the seat ring 7.

[0009] The end face of the end cap 1 is parallel to the end face of the seat ring 7 and perpendicular to the wire core.

[0010] The guide wheel 11 has a rounded chamfer on its end face.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] This invention can be easily installed on existing concentric wrapping heads; the guide wheel position of this invention is adjustable, suitable for wrapping wire cores of different diameters; this invention can completely balance the radial force applied to the wire core by the wrapping tape, preventing the wire core from bending and ensuring the wrapping tape is wrapped smoothly; this invention can effectively avoid wire core twisting and jumping caused by unstable wire tension; this invention has a simple and reliable structure, is easy to use, and is easy to promote and use.
