1, Definition and function of extruder head
An extruder is a device that uses mechanical, thermal, and chemical principles to process materials such as plastic or rubber into the desired shape, with the extruder head being one of the core components of the extruder. It is used to heat, melt, and plasticize solid plastics, and extrude them under a certain pressure to achieve product molding.
2, Installation position of extruder head
Normally, the extruder head is installed at the upper end of the extruder structure. Specifically, the machine head is connected to the screw of the extruder, and the rotation of the machine head is driven by the movement of the screw to extrude the molten plastic material into shape through the machine head.
During the installation process of the extruder head, the following details should be noted:
1. Before installation, the machine head needs to be cleaned and inspected to ensure that there are no residues inside the machine head, and to ensure the forming accuracy and product quality;
2. Special tools and standard threaded connections should be used during installation to ensure a stable connection between the head and extruder;
3. The angle and opening size of the machine head need to be adjusted according to production needs to ensure the size and appearance quality of the product;
During routine maintenance, the machine head should be regularly cleaned, inspected, and repaired to extend its service life.
3, Types and selection methods of extruder heads
The extruder head can be divided into various types based on the different formed products, such as single-layer head, multi-layer head, nozzle extruder head, etc. When choosing a nose, the following factors need to be considered:
1. Size, precision, and appearance requirements for molded products;
2. Production process, production efficiency, and cost control;
3. Factors such as the applicability, adjustability, and stability of the machine head.
4, Summary
The extruder head is one of the core components of the extrusion molding machine, installed at the upper end of the extruder structure. Attention should be paid to multiple details when installing the machine head to ensure molding accuracy and product quality. When choosing a machine head, it is necessary to consider factors such as the requirements of the molded product, production process, and economic benefits.
