Description

TECHNICAL FIELD

[0001] The utility model relates to cable processing technical field, concretely is a kind of cutting device for cable production winding. BACKGROUND

[0002] In the cable production process, winding and cutting are two crucial links. After extrusion, cooling, traction and a series of processes, the cable needs to be wound neatly and tightly on the winding device for subsequent storage, transportation and use. In the winding process, in order to achieve accurate control of the length of the cable and facilitate subsequent processing, the cable often needs to be cut at a specific position.

[0003] The existing cutting device lacks a dynamic clamping compensation mechanism after completing cable cutting, resulting in the cable end relaxing and sagging due to the disappearance of instantaneous tension, causing the winding end to be loose and the layers to be misaligned, which seriously affects the regularity of the wound material. Therefore, some devices clamp and constrain the cable, such as the utility model disclosed in Patent No. 202021923631.8, which uses friction rollers and fixed springs to clamp the cable, keeping the cable in a relatively tight state. However, in actual use of the cutting device, when the cable is fully received, the clamping structures on both sides will be squeezed towards the center, blocking the path of the subsequent cable. At this time, the two clamping structures need to be manually reset, then the cable is passed through and then released, allowing the clamping mechanism to clamp the cable again. This operation is relatively cumbersome and affects the efficiency of cutting and winding, so a new technical solution is needed to solve this problem. UTILITY MODEL CONTENTS
