Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an overflow glue cleaning device for a welding machine. Background Art

[0002] Hot melt riveting machine is a kind of mechanical equipment specially used for hot melt riveting process of plastics. It combines the functions of heating, pressurizing and pressing, and can quickly and accurately complete the connection of plastic parts, or the connection of plastic parts with parts of other materials.

[0003] The Chinese utility model patent disclosed by the existing publication number CN203510720U: a hot riveting mechanism, the application is convenient to adjust the hot riveting mechanism from the hot riveting mechanism fixing plate through the structural setting, but when the hot riveting head heats and melts the plastic part, such as using a hot melt riveting machine to limit and fix the metal ring on the plastic column, the metal ring is placed at a predetermined position of the plastic column for pre-positioning, and then, the heating and pressurizing function of the hot melt riveting machine is used to melt the connecting surface of the plastic column, and the contact surface of the metal ring and the plastic column will also be affected by the hot melt. Next, one end of the plastic column is melted and It is tightly combined with the surface of the metal ring, and a certain pressure is applied to ensure that they are in full contact. Under the action of pressure, the molten plastic will fill the gap between the connecting surfaces to form a tight connection. Therefore, part of the molten plastic will overflow outward along the upper surface of the metal ring due to the extrusion of the hot rivet head, so that the end of the molten plastic column is in an irregular shape, which may affect the composition and aesthetics of the later plastic parts. Therefore, after some metal rings are fixed on the plastic column by the hot melt riveting machine, the end of the plastic column needs to be manually polished again, resulting in a certain increase in labor costs and a decrease in production efficiency.
