Abstract

The invention discloses a multicolor multi-label cable producing device and a manufacturing method, and relates to the technical field of color labeled cable production. The producing device comprises a plastic extrusion mould cover, a plastic extrusion mould sleeve, a plastic extrusion mould seat, and at least one set of injection moulding channels; the plastic extrusion mould cover is inserted into the plastic extrusion mould sleeve, the plastic extrusion mould sleeve is inserted in the plastic extrusion mould seat; the plastic extrusion mould cover is a cylinder, a hollow discharging cavity is arranged in the plastic extrusion mould cover, the front end surface of the plastic extrusion mould cover is provided with a channel outlet and a discharging hole that is communicated with the discharging cavity, the channel outlet is communicated with the discharging hole; the plastic extrusion mould sleeve is a hollow cylinder, the front end surface of the plastic extrusion mould sleeve extends outwards to form a circular platform; the plastic extrusion mould seat is a hollow cylinder, the external side wall of the end of the plastic extrusion mould seat is provided with a circular groove, and the circular groove connects the plastic extrusion mould seat and the head of a peripheral external protective plastic extruding machine through a press cover. The provided device can strictly control the thickness of color labels, is capable of producing various multicolor multi-label cables through adjusting the injection channels, and can strictly control the sizes and positions of color labels.

Description

Technical field [0001] The invention relates to the technical field of color-code optical cable production, in particular to a multi-color multi-standard optical cable production device and manufacturing method. Background technique [0002] The color code of the optical cable and the regularity of the outer sheath have an important influence on the use and laying of the optical cable. The limitations of the number, color, and size of the color code also affect the overall appearance of the optical cable and the distinction of the optical cable during use. [0003] However, since the conventional color code optical cable production process is to open the runner on the die sleeve, the contact point of the color code material and the sheath material is in the extruder head. Due to the large extrusion volume in the head, the extrusion volume of the color standard material is also large in order to ensure the width of the color code. Therefore, the thickness of the color code is incr...

Problems solved by technology

Therefore, the thickness of the color code is increased, resulting in inconsistent shrinkage of the outer sheath material and the color code material, resulting in a lot of inconvenience to the laying and use of the optical cable due to the protrusion and depression of the color code, and at the same time affecting the wall thickness uniformity of the outer sheath of the optical cable.
