Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of extruders, in particular to a traction mechanism of an extruder. Background Art
[0002] When processing plastic pellets, the melted raw materials are usually extruded into plastic strips by an extruder, and then pulled by an external traction mechanism. According to a traction mechanism for a plastic pellet extruder with application number CN218660378U, the plastic strip extruded by the external plastic extruder passes through the right side of the opening at the upper end of the guide bar and passes out from the left end of the guide bar, and the left end of the plastic strip is located between the driven shaft and the leftmost traction roller, which is convenient for the plastic strip to pass out. At the same time, the guide bar cooperates with the limiting groove to facilitate the isolation and limitation of multiple plastic strips, which can play a limiting role on the plastic strips. However, when extruding plastic strips of different diameters, the fixed plate and the traction roller, as well as the driven shaft and the traction roller, are fixed in position, which makes it impossible to adapt to the traction needs of plastic strips of various diameters, resulting in poor adaptability of the traction mechanism.
