简体中文The connection between the screw barrel and the extruder head is a crucial part of the extrusion process. In order to ensure the stability and continuity of the extrusion process, an effective connection method is crucial. Common connection methods include threaded connections, flange connections, conical connections and quick connection devices. The choice of these connection methods depends on the design of the extruder head and screw barrel and production needs.
Threaded connection is a common connection method, usually used to connect the extruder head and screw barrel. Through the tight fit of the threads, the connection can be tightened and stabilized to ensure that there will be no loosening or falling off during the extrusion process. Another common connection method is flange connection, in which the connecting part of the extruder head and the screw barrel is equipped with a flange, and the two parts are firmly connected together by bolts during the connection. This connection method is usually suitable for situations where there are high requirements for connection stability.
In addition to threaded and flanged connections, conical connections are also a common option. This connection method uses a cone design to achieve a tight fit at the connection and provide a larger connection area, thus increasing the stability and sealing performance of the connection. In addition, quick connection devices are also widely used in situations that require frequent replacement, such as when extruder heads or screw barrels need to be replaced regularly. These devices usually use buckles, pins or other quick fixing devices, which can be quickly connected or disassembled without using tools, improving production efficiency and ease of operation.
Regardless of the connection method used, sealing performance is a key consideration in connection design. Usually, sealing gaskets or other seals are used at the connection to ensure the sealing performance of the connection and prevent material leakage. In addition, adjustment devices are often designed at the connection to adjust the tightness and pressure of the connection as needed to ensure the stability and reliability of the connection.
