Description

Technical Field

[0001] The utility model relates to a welding machine, in particular to a double-station vertical welding machine. Background Art

[0002] At present, there are two types of filter element end cap welding machines. One is horizontal hot plate contact welding. This type of welding product will cause glue overflow at the end cap welding part, yellowing during welding, and the end cap will be welded off-center, which has a great impact on the length size. It is not suitable for PFA filter element welding and will bring a large amount of metal impurities to the filter element. The other is a horizontal infrared non-contact welding machine. This type of welding is characterized by unstable infrared heating temperature, poor and uneven melting of the end cap and filter element, more on one side and less on the other side, unqualified bubble point, and a scrap rate of 30%-40%.

[0003] The above two welding equipment and welding methods have common disadvantages:

[0004] 1. In horizontal welding, the solution always drips downward, and the solution melts unevenly;

[0005] 2. The filter element clamping part cannot rotate at the same time;

[0006] 3. It can only be used as a single machine, not for multiple uses, which is costly and wastes resources;

[0007] 4. It will cause problems such as large welding size deviation, crookedness, and glue overflow on the filter element;
