A high temperature resistant cable extruder

Abstract

The invention discloses a high temperature resistant cable extruder, which comprises an extruding cylinder box, a plastic fixing device and a rotating discharge cylinder. The middle part of the extruding cylinder box is provided with a through cavity, and the top of the left end of the extruded cylinder box is opened with a The material inlet communicates with the through cavity, and several installation grooves are opened inside the extruded barrel box, and the cavity wall of the material inlet is fixedly connected with the outer end surface of the hopper. The invention uses a heater to heat the barrel wall to soften the raw material, so that the propulsion screw rotates to push the raw material into the molding device, and the fan sends the cold air flow through the cold plastic plate to the cold flow chamber, so that the material is rapidly cooled and shaped , the overall efficiency of extrusion is greatly improved, and the life loss of the extruder under long-term high-temperature operation is reduced; in addition, the automatic discharge delivery function is realized by rotating the discharge cylinder, and the sliding structure of the rotating arc plate and the push plate reduces In the process of material processing, the heat cannot be dissipated due to blockage, which reduces the service life of the extruder and improves the heat resistance.

Description

technical field [0001] The invention relates to the technical field of extruders, in particular to a high temperature resistant cable extruder. Background technique [0002] The extruder is an important plastic machine, and the production and manufacture of most plastic products can be realized by extrusion molding. The extruder motor is an important part of the extruder, and is the prime mover of the extruder, providing the large thrust required by the extruder screw. A low-speed high-torque permanent magnet direct-drive motor is designed for the current general-purpose 90mm screw extruder, which has many advantages such as high efficiency, high power density, good energy saving, high reliability, and high control precision. When the traditional extruder is working, the plastic in the barrel is a plastic colloid in a high-temperature molten state, and the permanent magnet motor is directly connected to the screw of the extruder, which will have a negative impact on the tem...

Problems solved by technology

[0003] Similarly, in the production process of cables, the participation of extruders is often required. This kind of special extruders, due to the extremely high temperature required in the cable preparation process, can easily cause slow damage to the extruder body that is difficult to repair. damage

Therefore, the traditional extruder has great innovation and improvement in high temperature resistance, and the long-term high temperature working environment is likely to greatly reduce the working life of the extruder and increase the equipment investment cost.
