Description

Technical Field

[0001] The utility model relates to the field of cable sheath production equipment, in particular to an extruder for cable sheath production. Background Art

[0002] Cable is a conductive material used to transmit electrical energy or signals. It is usually composed of a conductive core and an insulation layer. Cables are widely used in power transmission, communication, control and other fields. The cable sheath is an important component of the cable. It mainly protects the internal conductor and insulation layer of the cable. It can also prevent the intrusion of external impurities and moisture. The cable sheath is usually composed of one or more layers of materials, including rubber, plastic, metal, etc.

[0003] At present, the production of cable sheath is a process involving multiple steps and technologies, and its main purpose is to provide protection and insulation for the conductor of the cable. Therefore, an extruder is needed in the production process of the cable sheath. When the existing extruder produces the cable sheath, the plastic particles are placed from the discharge port into the inside of the horizontal frame through the discharge port, and the drive motor is started to drive the rotating rod and the spiral blade to rotate, and the plastic particles that fall into the processing box are transported to the heating part, so as to melt the plastic particles. However, after the existing extruder has been running for a long time, some residues may accumulate on the inner wall of the screw and the barrel, and these residues may cause blockage in the subsequent production process. However, since the machine body is arranged as an integrated unit, when a blockage or other fault occurs in the extruder, the machine body needs to be disassembled as a whole to inspect the inside of the machine body, which may increase the difficulty of maintenance, and may also cause the machine body to be damaged during disassembly and reinstallation, and cause production interruption, affecting production efficiency.

[0004] This not only increases the difficulty of maintenance, but may also cause damage to the body during disassembly and reinstallation.
