High-temperature-resistant cable plastic extruding machine

Abstract

The invention discloses a high-temperature-resistant cable plastic extruding machine which comprises a plastic extruding barrel box, a fixed plastic device and a rotary discharging barrel. A through cavity is formed in the middle of the plastic extruding barrel box, a feeding opening is formed in the top of the left end of the plastic extruding barrel box to communicate with the through cavity, multiple mounting grooves are formed in the plastic extruding barrel box, and the cavity wall of the feeding opening is fixedly connected with the outer end face of a hopper. The barrel wall is heated through heaters to soften raw materials, a propelling screw rotates to carry out plastic extruding forming on the raw materials and push the raw materials into the fixed plastic device, cold airflow istransmitted into a cold flow cavity by a fan through a cold plastic plate, the materials are quickly cooled and shaped, the plastic extruding efficiency is overall improved greatly and lift shortening of the plastic extruding machine under long-time high temperature work is reduced; and in addition, the functions of automatic discharging and transmitting are achieved through the rotary discharging barrel, through the rotating sliding structure of arc plates and propelling plates, the problems that heat cannot be dissipated due to blocking in the material processing process, and the service life of the plastic extruding machine is shortened are reduced, and heat resistant performance is improved.

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.
