Specifically, in step S100 of the filter element processing method, the circumferential side wall of the filter element 100 is shaped and positioned; the filter element 100 is soft, and under the condition of no stress, the outer diameters of different positions of the circumferential side wall of the filter element 100 are different, so that the end surface of the filter element 100 is uneven, the filtering effect of the filter element 100 is influenced, the shaping and positioning procedures are added, and an acting force is applied to the middle part of the circumferential side wall of the filter element 100, so that the outer diameters of two ends of the filter element 100 are kept the same, and the cylindricity error of the filter element 100 is reduced; this plastic positioning process and filter core positioning jig 25's positioning process independently go on, and reducible filter core positioning jig 25's size is convenient for place filter core 100, can alleviate filter core positioning jig 25 design degree of difficulty simultaneously, reduces filter core positioning jig 25's processing cost.

Specifically, in step S400, the filter element positioning jig 25 is pressed to move the filter element positioning jig 25 toward the second end of the filter element 100; the filter element positioning jig 25 extrudes the second end of the filter element 100, and applies equal force to the first end and the second end of the filter element 100 respectively, so that the flatness of the two ends of the molded filter element 100 of the filter is improved; further, two ends of the filter element 100 are gradually extruded, and a mode of heating and pressurizing is adopted, so that the rubber ring is timely adhered to the end part of the filter element 100 after being melted; second, the filter element positioning jig 25 may be provided at both ends of the filter element 100.

Specifically, in step S100, two filter element positioning jigs 25 are provided, wherein one of the filter element positioning jigs 25 is provided at a first end of the filter element 100, and the other one of the filter element positioning jigs 25 is provided at a second end of the filter element 100; be provided with packing ring 102 and film 101 in two filter core positioning jig 25, two filter core positioning jig 25 set up respectively at the both ends of filter core 100, process the both ends of filter core 100 simultaneously, improve the machining efficiency of filter core 100, adopt the mode that both ends were processed simultaneously, avoid the step of filter core 100 upset, further improve machining efficiency.

Specifically, in step S400, the filter element 100 is continuously pressed within a preset time, so that the melted rubber ring is bonded more sufficiently, and after the preset time, the filter element 100 is loosened and the filter element 100 is cooled, so that the melted rubber ring is solidified.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
