Description

Technical Field

[0002] Wedge screen is a specially designed screen, usually used in the process of solid-liquid separation or solid-gas separation. It is characterized by a gradually tapering opening, which can effectively separate particles or substances of different particle sizes. Wedge screens are usually used in industries such as mining, chemicals, and building materials for screening, filtering, and separating particles. At the same time, wedge screens are usually made of metal wire or metal plate. Their structural design allows them to withstand greater forces and pressures during use while maintaining stable screening performance.

[0003] In order to fix the structure of the screen and ensure its stability, workers use western medicine to perform spot welding at the intersection of the screen and the connection between the screen and the bracket, which can effectively fix the mesh or bracket of the screen to prevent it from loosening or shifting during use. When performing spot welding operations, existing spot welding devices can usually only perform single-sided welding at the intersection of the screen and between the screen and the bracket. If the welding effect needs to be better, the operator is often required to turn over the screen and bracket on one side that has been welded. This not only increases labor costs and working time, affects production efficiency and production capacity, but also the high-temperature welding environment and operating requirements also increase the safety risks of the operator, especially in a busy production environment, where accidents are prone to occur. In addition, existing spot welding machines usually weld at right angles to the spot welding position during welding, and welding is prone to dead angles and poor quality. Summary of the invention
