[0037] Example 1

[0038] like Figure 1-5 As shown, the utility model is a filter element trimming device, comprising: a bracket 1, an X, Z dual-axis module 2, a rotary cutting module 3, a first positioning module 4, a second positioning module 5, and a positioning clamp 6. Specifically:

[0039] like Figure 2 As shown, the X, Z dual-axis module 2 includes: an X-axis screw mechanism 21, and a Z-axis cylinder mechanism 22 connected to the X-axis screw mechanism 21; by setting the X-axis screw mechanism 21 and the Z-axis cylinder mechanism 22, the feeding accuracy of the rotary cutting module 3 on the X-axis and Z-axis can be accurately controlled to improve the accuracy and efficiency of the filter element cutting edge.

[0040] like Figure 2 As shown, the X-axis screw mechanism 21 includes: two first slide rails 211 arranged in the X-axis direction, a first slider 212 slidably connected to the first slide rails 211, a screw rod 213 between the two first slide rails 211, a screw rod 213 nut connected to the screw rod 213, and a Z-axis cylinder mechanism 22 connected to the first slider 212 and the screw rod 213 nut; the X-axis screw mechanism 21 drives the Z-axis cylinder mechanism 22 and the rotary cutting module 3 to move in the X-axis direction, thereby adjusting the cutting distance of the filter element.

[0041] like Figure 2As shown, the Z-axis cylinder mechanism 22 includes: a first sliding plate 221 connected to the first slider 212 and the screw 213 nut, two second slide rails 222 arranged on the first sliding plate 221 in the Z-axis direction, a second slider 223 slidably connected to the second slide rail 222, a second sliding plate 224 connected to the second slider 223, and a cutter cylinder 225 connected to the first sliding plate 221 and having a telescopic end connected to the second sliding plate 224, and the peeling module 3 is connected to the second sliding plate 224; the Z-axis cylinder mechanism 22 drives the peeling module 3 to move in the Z-axis direction, and when peeling is required, drives the peeling module 3 to move downward to perform edge cutting, and when peeling is completed, drives the peeling module 3 to lift.

[0042] like Figure 4 As shown, the peeling module 3 includes: a fixed base 31, a peeling motor 32 and a peeling knife 33. The fixed base 31 is connected to the second sliding plate 224, the peeling knife 33 is connected to the fixed base 31 through an axis, the peeling motor 32 is connected to the other side of the fixed base 31 through a motor base, and the output shaft end of the peeling motor 32 is connected to the rotating cutter; the peeling knife 33 is driven to rotate and cut through the rotation of the output shaft of the peeling motor 32.

[0043] like Figure 2 As shown, the first positioning module 4 includes: a first X-axis moving module 41, and a first ejector pin 42 connected to the first X-axis moving module 41; the end of the first ejector pin 42 is conical and can be inserted into the center hole of the filter element and support one end of the filter element. The first ejector pin 42 is a driven ejector pin.

[0044] The second positioning module 5 includes: a second X-axis moving module 51, a second ejector pin 52 connected to the second X-axis moving module 51, and a positioning rotary motor 53 driving the second ejector pin 52 to rotate; the second ejector pin 52 has a mating key 521 on the outside thereof that is mated with the filter element; Figure 3 As shown, the end of the filter element has an opening. When the second ejector pin 52 is inserted into the center hole of the filter element, the matching key 521 is inserted into the opening and limited therewith, thereby achieving the purpose of smoother and more stable rotation of the filter element, ensuring the stability of the peeling, and achieving the beneficial effect of improving the peeling accuracy and the flatness of the peeled surface.

[0045] The external structure of the second ejector pin 52 of this embodiment matches the internal structure of the center hole of the filter element.

[0046] like Figure 1 As shown, the positioning jaws 6 of this embodiment are connected to the bracket 1 through the mounting frame, and are used to clamp the filter element between the first positioning module 4 and the second positioning module 5; before the first positioning module 4 and the second positioning module 5 complete the positioning and clamping, the filter element is clamped by the positioning jaws 6 to facilitate the positioning of the first positioning module 4 and the second positioning module 5.

[0047] In this embodiment, the X-axis screw mechanism 21 is manually driven or motor driven to control the trimming distance in the X-axis direction.

[0048] Preferably, a buffer 23 for buffering the movement of the Z-axis cylinder mechanism 22 is provided on the side of the Z-axis cylinder mechanism 22. By providing the buffer 23, the downward cutting action of the rotary cutting module 3 driven by the Z-axis cylinder mechanism 22 can be buffered, thereby slowing down the feed speed of the rotary cutter 33, improving the cutting stability, avoiding the problem of knife burning caused by excessive speed and heat accumulation, improving the cutting quality, and extending the service life of the rotary cutter 33.

[0049] The working principle of this embodiment is as follows: the filter element is moved to the positioning clamp 6 by an external moving mechanism, and the filter element is clamped by the positioning clamp 6; the first X-axis moving module 41 drives the first ejector pin 42 to move rightward, so that the first ejector pin 42 supports one end of the filter element; the second X-axis moving module 51 drives the second ejector pin 52 to move leftward. If the matching key 521 is not aligned with the filter element, the second ejector pin 52 is rotated by the positioning rotating motor 53, so that the matching key 521 and the filter element are aligned, and the second ejector pin 52 supports the other end of the filter element. The positioning rotating motor 53 drives the filter element to rotate through the second ejector pin 52; the X-axis screw mechanism 21 drives the Z-axis cylinder mechanism 22 and the peeling module 3 to move in the X-axis direction to determine the lower cutting position of the peeling knife 33; the peeling motor 32 drives the peeling knife 33 to rotate, and the Z-axis cylinder mechanism 22 drives the peeling knife 33 to move downward in the Z-axis direction for cutting.

[0050] By setting up an X and Z dual-axis module to drive the peeling module 3 to feed and cut, and by using the first positioning module 4 and the second positioning module 5 to position and clamp the filter element, the feeding accuracy of the peeling module 3 on the X and Z axes is guaranteed, and the accuracy and efficiency of the filter element cutting are improved. By setting a mating key 521 on the outside of the second ejector 52 to cooperate with the filter element limit plug-in, the purpose of smoother and more stable filter element rotation is achieved, the stability of peeling is guaranteed, and the beneficial effect of improving the peeling accuracy and the flatness of the peeled surface is achieved. The overall device realizes high-precision and high-efficiency cutting work.
