Description

Technical Field

[0001] The utility model belongs to the technical field of filter processing, in particular to a filter shell edge sealing device. Background Art

[0002] A filter is an accessory that filters impurities or gases through filter paper. It is divided into oil filters, fuel filters (gasoline filters, diesel filters, oil-water separators, hydraulic filters), air filters, air conditioning filters, etc. according to their different filtering functions. According to their appearance, they are generally divided into cartridge and plate types. When cartridge filters are processed, they are mostly sealed by an edge sealing machine.

Since the bottom of some filters is arc-shaped, the filter may tilt when placing the filter on the lifting platform of the edge banding machine, which may cause deformation of the filter during edge banding. Therefore, a filter housing edge banding device is needed. The filter housing can be fixed by a positioning structure to avoid deformation caused by tilting of the filter during edge banding, thereby ensuring the stability of the filter during edge banding.
