Description

Technical Field

[0001] The utility model relates to the technical field of welding rod production, in particular to a pressing rod device used for welding rod production. Background Art

[0002] Welding rods consist of a core and a coating. The coating (coating) is evenly and centripetally applied to the metal core. Different types of welding rods have different cores. To ensure weld quality and performance, the content of each metallic element in the core is strictly regulated. In particular, the content of harmful impurities (such as sulfur and phosphorus) is strictly limited, exceeding that of the parent metal.

[0003] Most existing welding rod pressing devices can only produce welding rods of fixed specifications. For example, the utility model with patent number CN219822583U, although this device can complete the task of producing welding rods, its internal pressing mechanism lacks adjustment function, which means that it cannot adapt to the production needs of welding rods of different diameters. This design defect causes the equipment to only produce welding rods of limited specifications and cannot meet diverse market demands. In addition, the device also has problems with the design of the conveyor belt. There is no auxiliary device inside the conveyor belt, and the conveyor belt itself is made of flexible material, which leads to difficulties in the process of pressing the welding rod. When the welding rod is detached from the pressing roller, due to the flexible characteristics of the conveyor belt, it is impossible to continue to effectively maintain the pressed state of the welding rod, which may affect the overall quality and performance of the welding rod.
