A kneading extrusion device

Abstract

The invention discloses a kneading and extruding device, which comprises a barrel, an extruding screw and a driving motor. The direction is provided with feeding section, primary mixing section, first exhaust feeding section, shear mixing section, second exhaust feeding section, kneading section and discharge extrusion section; the peripheral wall ring of primary mixing section is provided with let There are multiple stirring rods in the recess, the inner wall of the barrel is provided with a guide ring, the shear mixing section is equipped with multiple first dispersing discs, the inner wall of the barrel is provided with a second dispersing disc, and the second dispersing disc is provided on the inner wall of the barrel. The second dispersing discs are arranged alternately with the first dispersing discs. The combination of material mixing and extrusion completely solves the problem of insufficient mixing of traditional mixing devices, improves product quality, and reduces production equipment and production costs. After cross-linking, the material has high structural strength and better mechanical properties. and resistance to environmental stress cracking.

Description

Technical field [0001] The present invention belongs to the field of cable production equipment, in particular, to a kneading extrusion device. Background technique [0002] With the rapid development of the global economy and the continuous strengthening of environmental protection and fire safety awareness, green environmental protection, low carbon energy saving, fire safety becomes focus on the construction industry. On the other hand, with the development of the city, the high-rise building on the ground increases, the demand for wire and cable is getting bigger and larger, the radiation intensity is getting higher and higher, because the quality of wire and cable causes fire safety accidents, low Smoke, halogen-free, flame retardant, fire, environmental protection, and safety have become the direction in which the wire and cable areas are jointly developed. [0003] After crosslinked low-smoke-free halogen-based hydrocarbons, after crosslinking of the insulating material, i...

AI Technical Summary

Problems solved by technology

The traditional mixing device relies on the mixing blade to shear and disperse the materials. During the mixing process, most of the materials rotate near the inner wall of the mixing container without being sheared and dispersed by the mixing blades, resulting in uneven mixing of materials A and B.

In addition, only intermittent production can be carried out by mixing with mixing equipment, and the mixing equipment and the extruder cannot be connected into a continuous production line. The production efficiency is low, and there may be differences between different batches of products, and the product quality is stable. poor sex
