Mold outlet drooling removal device

Abstract

The invention discloses a mold outlet drooling removal device. The mold outlet drooling removal device comprises an air blowing mechanism (1) and an air supply mechanism (2), wherein the air blowing mechanism (1) comprises an air cavity (1000), multiple air holes (1002) communicating with the air cavity (1000) and a through hole (11) for an optical cable outer sheath (3)to penetrate through, the air supply mechanism (2) supplies air to the air cavity (1000), and the air holes (1002) are aslant formed and make air blown to the outer sheath (3) penetrating through the interior of the through hole (11). According to the mold outlet drooling removal device, through the arrangement of the air blowing mechanism and the air supply mechanism for blowing air to the air blowing mechanism, and the formation of the air cavity and the air holes in the air blowing mechanism, air can be blown to the surface of the outer sheath through the air holes, then drooling on the surface of the outer sheath isblown off, automatic clearing of the drooling is achieved, and the improvement of the production quality of the outer sheath is facilitated.

Description

technical field [0001] The invention relates to the technical field of optical cable manufacturing, in particular to a device for removing drool at a mold outlet. Background technique [0002] At present, people's production and life are inseparable from optical fiber communication, the demand for optical cables is increasing day by day, and the requirements for the quality of optical cables are also getting higher and higher. The outermost layer of the cable is usually the outer sheath, which is formed by extrusion. The sheath material is heated and extruded in the extruder, wraps the cable inside, and forms an outer sheath after cooling and solidifying. [0003] Since the sheath material itself contains impurities and cannot be screened out (some impurities stick together with the sheath material), a layer of impurities will be formed at the extrusion end of the extruder when the sheath material is extruded. This is because the sheath material is heated and melted in the...

AI Technical Summary

Problems solved by technology

When the sheath material is extruded, it will come into contact with drool, which will affect the cooling of the sheath material. At the same time, the sheath material at the extrusion end is not solidified and has a high viscosity. The material re-solidifies together, which affects the production quality of the outer sheath; in addition, when the sheath material is extruded, it is first cooled in the air, and the sheath process is not a constant temperature workshop, so the temperature change in the workshop has a certain impact on the quality of the outer sheath. It is not conducive to ensuring the stability of the quality of the outer sheath
