In another embodiment of the present invention, as shown in fig. 14 to 15, the trimming device 60 further includes an air blowing anti-sticking air gun for blowing away the cutting waste and a release agent spraying anti-sticking air gun for spraying the release agent, specifically, the air blowing anti-sticking air gun blows air when cutting the edge each time, the release agent spraying anti-sticking air gun sets the number of spraying times according to the actual requirement, and when the number of cut edges reaches the set number, the release agent spraying is performed once, and the time of spraying is set according to the requirement. The blowing anti-sticking air gun and the release agent spraying anti-sticking air gun can prevent residual glue from attaching to the material placing gap 65 to affect the normal work of the trimming device 60.

The structure and the working principle of the edge trimming device 40 are substantially the same as those of the trimming device 60, and therefore, for the specific structure of the edge trimming device 40 for trimming the filter element after the edge strip, details are not repeated herein in this embodiment.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
