Description

Technical Field

[0001] The utility model relates to the technical field of optical cable stripping machines, and more specifically, to a guiding mechanism of an optical cable stripping machine. Background Technique

[0002] An optical cable is manufactured to meet the performance specifications of optics, mechanics or environment. It is a communication cable assembly that uses one or more optical fibers placed in a coated sheath as a transmission medium and can be used alone or in groups. The optical cable mainly consists of optical fibers, plastic protective sleeves and plastic outer skins. Inevitably, various abnormal problems will occur during the production process of optical cables. For example, if the attenuation index of the optical fibers in the optical cable is unqualified, the process needs to be adjusted to re-sheath; if there are appearance or dimensional unqualified in the production of optical cables, the optical unit part needs to be utilized. At this time, the optical cable needs to be stripped.

[0003] After retrieval, the utility model patent with the publication number of CN219552695U discloses an optical cable stripping machine, which includes a workbench surface, a guiding mechanism and a stripping mechanism. The guiding mechanism includes a support frame, an upper pressing wheel group, a lower supporting wheel group and a lifting cylinder. The support frame includes a vertical rod and a top plate. The upper pressing wheel group and the lower supporting roller group are both arranged below the top plate. The upper pressing wheel group includes a first connecting seat and two groups of upper pressing wheels arranged below the first connecting seat. The lower supporting wheel group includes a second connecting seat and two groups of lower supporting wheels arranged above the second connecting seat. And the two groups of upper pressing wheels are respectively corresponding to the two groups of lower supporting wheels up and down one by one. The second connecting seat is fixed on the workbench surface, and the piston rod of the lifting cylinder is fixedly connected to the top surface of the first connecting seat. The stripping mechanism is arranged between the two groups of lower supporting wheels; through the guiding mechanism and the stripping mechanism, the device can quickly and stably strip the optical cable, and is suitable for optical cable manufacturers to batch strip ordinary optical cables.

[0004] However, the above patent still has the following deficiencies: when stripping the optical cable, generally, the upper pressing wheel and the lower supporting wheel arranged up and down are used to guide the optical cable. However, due to the different outer diameters of the optical cables, only the optical cables with the same inner diameter as the grooves of the upper pressing wheel and the lower supporting wheel can be guided, and the practicability is poor; and when the optical cable is inserted between the upper pressing wheel and the lower supporting wheel from the outside, it is not easy to ensure that the optical cable is in a horizontal state, which affects the smooth operation of the stripping machine. Therefore, we propose a guiding mechanism of an optical cable stripping machine. Content of the Utility Model
