Description

Technical Field

[0001] The utility model relates to the technical field of cable extruders, in particular to a screw taking-out mechanism for a cable extruder. Background Art

[0002] In the traditional plastic processing industry, cable extruder is a commonly used equipment, mainly used for plastic melting, extrusion and other processes. One of the core components of the cable extruder is the screw, which is responsible for pushing and heating the plastic raw materials to melt and extrude them through the die. However, during long-term use, the screw needs to be removed and replaced due to wear, damage or the need to replace screws of different specifications to meet different production needs.

[0003] Chinese patent publication number "CN218803869U" discloses a linkage type low-smoke halogen-free cable material uniform extruder, which can make the cable material particles enter the extruder in small quantities and multiple times when the cable material is extruded and melted by the extruder, thereby ensuring the uniformity of the extruder operation, ensuring the quality of the cable and being able to quickly and easily remove the screw for repair or replacement after the screw is severely worn in the extruder.

[0004] In actual use, it is necessary to suspend the overall operation of the cable extruder, which usually involves shutting down the heating system, drive system and other related auxiliary systems. After the equipment has completely stopped working and the screw has cooled to a safe operating temperature, the operator can start to disassemble the extruder head and then remove the screw, which increases the complexity of production. More importantly, the screw replacement process will cause production to be suspended, resulting in reduced production efficiency. Utility Model Content
