[0030] In one embodiment of the present invention, referring to Figure 1-Figure 5 , a filter element edge strip punching device is provided, including a workbench 100.

[0031] Among them, refer to Figure 2 and Figure 3 A filter element placement platform 110 is provided at the upper end of the workbench 100, a punching plate 120 is provided at the rear side of the filter element placement platform 110, and at least one first punching groove 121 is penetrated by the punching plate 120. The workbench 100 is provided with at least one first punching knife 130, and the first punching knife 130 is matched with the first punching groove 121.

[0032] Among them, refer to Figure 2 and Figure 3 The workbench 100 is further provided with a driving mechanism 200, which is in transmission connection with the first punching knife 130. The filter element 300 is positioned and placed on the filter element placement platform 110 and one side bar of the filter element 300 abuts against the punching plate 120. The driving mechanism 200 is used to drive the first punching knife 130 to pass through the first punching slot 121, thereby punching out a first positioning hole 310 at a designated position of the side bar of the filter element 300.

[0033] Compared with the prior art, the one or more technical solutions in the filter element edge strip punching device provided in the embodiment of the utility model have at least one of the following technical effects:

[0034] Reference Figure 2 and Figure 3When working, the filter element 300 is first positioned and placed on the filter element placement table 110 with one side strip abutting against the punching plate 120, and then the driving mechanism 200 drives the first punching knife 130 to move forward through the first punching slot 121, and the first punching knife 130 cooperates with the first punching slot 121 to punch out the first positioning hole 310 at the specified position of the side strip of the filter element 300. There is no need to manually open the positioning hole on the side strip of the filter element 300, which not only has high punching accuracy but also high efficiency.

[0035] In another embodiment of the present invention, referring to Figure 3 and Figure 4 The driving mechanism 200 includes a driving unit 210, a linear guide 220 and a slider 230. The two linear guides 220 are symmetrically arranged on the workbench 100, and at least one slider 230 is slidably connected to each linear guide 220. A moving plate 240 is installed on the slider 230, and the first punching knife 130 is fixed on the moving plate 240. The filter element placement table 110 is penetrated by a slot 111, and the first punching knife 130 passes through the slot 111 and faces the first punching slot 121. The linear guide 220 cooperates with the slider 230 to play a guiding role, so that the first punching knife 130 can accurately reciprocate in and out of the first punching slot 121 under the drive of the driving unit 210, and the movement is stable.

[0036] Further, refer to Figure 3 and Figure 4 The driving unit 210 is a linear module, an electric cylinder or an air cylinder. The linear module, the electric cylinder or the air cylinder drives the first punching knife 130 to move forward or backward, so that the first punching knife 130 penetrates into and out of the first punching slot 121, and when the first punching knife 130 penetrates (passes through) the first punching slot 121, the first positioning hole 310 is punched out at a designated position of the side strip of the filter element 300, and the structure is simple.

[0037] Further, refer to Figure 2 and Figure 3 A positioning block 112 is provided on both sides of the filter element placement platform 110. The two positioning blocks 112 are used to position the left and right sides of the filter element 300 so that the filter element 300 is positioned and placed in the filter element placement platform 110, and the structure is reliable.

[0038] Further, refer to Figure 2 and Figure 3, a first adjustment slot 113 is provided on both the left and right sides of the filter element placement platform 110, and a first screw (not shown) passes through the first adjustment slot 113 from the bottom of the first adjustment slot 113 and is screwed to the positioning block 112, and the nut of the first screw is larger than the width of the first adjustment slot 113. Specifically, by loosening the first screw, the positioning block 112 can be pushed to move along the first adjustment slot 113, thereby adjusting the distance between the two positioning blocks 112 to adapt to filter elements 300 of different widths. After the adjustment is completed, tighten the first screw to fix the positioning block 112 on the filter element placement platform 110.

[0039] In another embodiment of the present invention, referring to Figure 3 and Figure 4 The two ends of the punching plate 120 are each provided with a second punching slot 122, and the movable plate 240 is symmetrically provided with two second punching knives 140, which are respectively matched with the two second punching slots 122. The driving mechanism 200 is used to drive the second punching knife 140 to pass through the second punching slot 122, so as to punch out second positioning holes at both ends of the side strip of the filter element 300, which is used in the occasion where the first positioning hole 310 and the second positioning hole need to be positioned simultaneously when the filter element 300 is installed, so as to meet the use requirements.

[0040] Further, refer to Figure 3 and Figure 4 The knife seat of the second punching knife 140 is fixedly mounted on the movable plate 240 by a plurality of second screws (not shown in the figure), which is easy to install and firmly connected.

[0041] In another embodiment of the present invention, referring to Figure 5 The punching plate 120 includes a left plate 123 and a right plate 124. The left plate 123 and the right plate 124 are each provided with a first punching slot 121 and a third adjustment slot 125. The two third adjustment slots 125 are each penetrated with a third screw 126, and the third screw 126 is screwed to the rear side wall of the filter element placement platform 110. The two first punching knives 130 are each provided on a connecting plate 131, and the two connecting plates 131 are each penetrated with a fourth adjustment slot 132, and the two fourth adjustment slots 132 are each penetrated with a fourth screw 133, and the fourth screw 133 is screwed to the moving plate 240. Specifically, by loosening the third screw 126, the left plate 123 or the right plate 124 can be pushed to move the adjustment position along the third adjustment slot 125, thereby adjusting the position of the first punching slot 121. By turning the fourth screw 133, the connecting plate 131 can be pushed to move the adjustment position along the fourth adjustment slot 132, thereby adjusting the position of the first punching knife 130 and making the first punching knife 130 face the first punching slot 121. Therefore, the position of the first punching slot 121 and the first punching knife 130 can be adjusted according to actual production requirements or the type of filter element 300, so as to punch out the first positioning hole 310 at different positions of the side strip of the filter element 300, which has extremely high practicality.
