High-performance heat-resistant combustion-supporting glass fiber reinforced nylon extrusion molding device

Abstract

The invention discloses a high-performance heat-resistant combustion-supporting glass fiber reinforced nylon extrusion molding device comprising a base and an extruder arranged on the base. The extruder comprises a material barrel, a reducer arranged at one end of the material barrel, a second motor arranged on the base and connected to the reducer through a belt in a transmission manner and an extrusion screw arranged in the material barrel; and one end of the extrusion screw is in transmission connection with the reducer, the second motor drives the reducer to work, and the reducer drives the extrusion screw to rotate. A discharge port is formed in the end, without the reducer, of the material barrel, a feeding barrel is arranged above the material barrel, an outlet of the feeding barrelcommunicates with the material barrel, and materials enter the material barrel from the feeding barrel and are extruded by the extrusion screw. A transition sleeve is arranged at the discharge port of the material barrel, and the opening diameter of an outlet of the transition sleeve is smaller than the opening diameter of an inlet of the transition sleeve. By arranging the transition sleeve withthe gradually-changed opening diameters at the discharge port of the material barrel, dead angles are avoided, material carbonization caused by accumulation can be avoided, and the normal and orderlyproduction is effectively ensured.

Description

technical field [0001] The invention relates to extrusion equipment, in particular to an extrusion molding equipment for high-performance heat-resistant and combustion-supporting glass fiber reinforced nylon. Background technique [0002] The extruder uses different screws when extruding and cladding different materials. Nylon becomes liquid after heating, and has strong fluidity, while ordinary screw cannot generate base pressure when extruding nylon, and when wrapping the core wire, it will sometimes be thick and sometimes thin or the supply will be insufficient. [0003] And because there is a big difference in the fluidity of the materials required for nylon production, some products with high temperature and low fluidity have very poor fluidity during production. During long-term non-stop production, if there is a dead angle at the exit, the plastic will slowly carbonize And block the discharge port. In the prior art, the screen plate provided at the outlet of the ext...

Problems solved by technology

Nylon becomes liquid after heating, and has strong fluidity, while ordinary screw cannot generate base pressure when extruding nylon.

[0003] And because there is a big difference in the fluidity of the materials required for nylon production, some products with high temperature and low fluidity have very poor fluidity during production. During long-term non-stop production, if there is a dead angle at the exit, the plastic will slowly carbonize And block the outlet

In the prior art, the mesh plate installed at the outlet of the extrusion molding device is flat, and there is a 90-degree dead angle between the die and the die, so the above-mentioned phenomenon that the plastic accumulated in the dead angle is easily carbonized and the outlet is blocked
