With fine-tuning high-precision four-layer co-extrusion head

Abstract

The invention discloses a high-precision four-layer co-extrusion machine head with fine adjustment, which includes a casing, a middle layer shunt, a rubber guide tube 1 and a connecting seat, the middle layer shunt is installed in the casing, and the casing 1 The first rubber guide tube is installed on the side wall. The beneficial effect is that: by setting the middle layer splitter, the inner layer splitter, the outer layer splitter and the color ring sleeve, during the material injection process, through the composite structure of the head splitter, multi-layer integrated co-extrusion can be realized Production not only ensures the extrusion effect of the device, but also ensures the extrusion efficiency of the device and improves the practicability of the device. By setting four deviation adjustment screws on the casing, the eccentricity between the conductor and the insulation can be adjusted. When adjusting, The axial position of the die sleeve is finely adjusted by the tightness of the four adjusting screws, so as to ensure that the conductor is located in the middle of the insulating layer, ensure the concentricity between the insulating layer and the conductor, and improve the functionality of the device.

Description

technical field [0001] The invention relates to the technical field of wire and cable extrusion heads, in particular to a four-layer co-extrusion head with fine adjustment and high precision. Background technique [0002] Wire and cable are used to transmit electrical (magnetic) energy, information and wire products that realize electromagnetic energy conversion. The generalized wire and cable is also referred to as the cable, and the narrow-sense cable refers to the insulated cable, which can be defined as: an aggregate composed of the following parts; one or more insulated cores, and their respective possible coverings, the total The protective layer and the outer sheath, the cable can also have additional conductors without insulation, and a co-extrusion head is required in the production process of the wire and cable. [0003] However, the existing co-extrusion head cannot realize multi-layer integrated co-extrusion production during use, which leads to the need for lay...

Problems solved by technology

[0003] However, the existing co-extrusion head cannot realize multi-layer integrated co-extrusion production during use, which leads to the need for layered extrusion, which not only affects the extrusion effect of the device, but also affects the extrusion efficiency of the device and reduces the practicability of the device , Secondly, the existing co-extrusion head is fixed during use, which leads to the inability to fine-tune the mold base, affects the concentricity between the conductor and the insulating layer, and reduces the functionality of the device. In addition, the existing The co-extrusion head has too much material during the injection process. Since the material supply cannot be notified quickly, it will lead to material waste and affect the production capacity of the device. Therefore, it is urgently needed to solve the current situation something wrong
