[0002] A cable double-layer co-extrusion extruder is an extruder device used to produce cables with a two-layer structure. The device allows two different materials to be extruded through independent extrusion mechanisms to eventually form a cable product with a two-layer structure. The positions between existing double-layer co-extrusion extruders need to be adjusted frequently to adjust the impact of changes in cable material specifications on the uniform extrusion of cable materials. Existing double-layer co-extrusion extruders generally adjust the positions between the extrusion mechanisms by manually dragging the extrusion mechanism at the front end of the production line. This adjustment method is time-consuming because the force of manual dragging is difficult to grasp, which affects the extrusion operation of the cable. In order to solve this problem, a new type of double-layer co-extrusion extruder is needed. Utility Model Content
