Description

Technical Field

[0001] This utility model relates to the field of extrusion molding technology, and in particular to an extrusion molding apparatus for welding materials. Background Technology

[0002] Extrusion molding machines are mainly divided into extruders and calenders. Calenders: The main working parts are rollers, usually three or more. When rubber material with a certain temperature and plasticity is fed into the gap between counter-rotating rollers, it is subjected to strong extrusion and stretching under friction to form the desired product. Welding materials refer to the general term for materials consumed during welding, such as welding rods, welding wires, metal powders, fluxes, and gases. With the rapid development of the welding industry, the demand for welding rods is becoming increasingly widespread.

[0003] In existing technologies, welding materials produce welding slag and impurities during the extrusion molding process. If these slag and impurities are not cleaned in time, they will adhere to the surface of the extrusion rollers. This will cause precision errors and affect the extrusion effect during the subsequent extrusion molding process. Traditionally, manual cleaning is used, and cleaning can only be done after the processing is completed. It is impossible to clean while extruding to improve efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an extrusion molding device for welding materials. Welding slag and impurities fall off and, if not cleaned in time, will adhere to the surface of the extrusion roller.
