Description

Technical Field

[0001] The invention belongs to the technical field of filter element production, and in particular relates to a filter element edge-adhering device. Background Art

[0002] There are two main methods for attaching edge strips to filter elements: manual and machine. To attach edge strips, the filter element is first placed on a workbench. The edge stripping machine then attaches the edge strips to one side of the filter element. The filter element is then rotated and the edge strips are attached to the other side, completing the filter element.

[0003] However, referring to Figure 1 For filter elements 10 that require affixing right-angled strips 11, the right-angled strips 11 are affixed to the sides and bottom of the filter element 10 to improve the firmness of the filter element 10. Current edge-attaching machines are unable to attach right-angled strips 11 to filter elements 10. The filter element 10 can only be attached by a human operator who first folds the strips into right-angled strips 11 and then manually attaches the right-angled strips 11 to the sides and bottom of the filter element 10. However, this method of manually attaching right-angled strips not only results in low processing efficiency and high processing costs, but also has low accuracy in edge-attaching, which can easily result in defective products.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0048] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0049] In one embodiment of the present invention, referring to Figures 1-12A filter element wedging device is provided, comprising a frame 300, a filter element conveying mechanism 310, and two cutting and gluing wedging mechanisms 320. The filter element conveying mechanism 310 is disposed on the frame 300 and is used to convey the filter element 10, and the two cutting and gluing wedging mechanisms 320 are symmetrically disposed on opposite sides of the filter element conveying mechanism 310.

[0050] Among them, reference Figure 1-Figure 3 The cutting, gluing, and wedging mechanism 320 includes a strip feeding mechanism 400, a strip cutting mechanism 500, a gluing mechanism 600, and a strip wedging mechanism 700, all of which are located on the frame 300. The strip feeding mechanism 400 is used to feed the strips 15. The strips 15 from the strip feeding mechanism 400 sequentially pass through the strip cutting mechanism 500 and the gluing mechanism 600 and enter the strip wedging mechanism 700. The strip cutting mechanism 500 is used to cut the strips 15 along their length, forming a fold 14 on the strips 15. The gluing mechanism 600 is used to glue the strips 15. The strip wedging mechanism 700 is located next to the filter element conveying mechanism 310 and is used to fold the strips 15 along the fold 14 to form a right-angled strip 11, and then adhere the right-angled strip 11 to the side and bottom of the filter element 10.

[0051] Compared with the prior art, the one or more technical solutions in the filter element edge-adhering device provided in the embodiment of the present invention have at least one of the following technical effects:

[0052] Reference Figure 1-Figure 3 During operation, a plurality of filter elements 10 to be edged are sequentially conveyed to the edge stripping mechanism 700 along the filter element conveying mechanism 310. The edge strips 15 of the edge strip feeding mechanism 400 sequentially pass through the edge strip cutting mechanism 500 and the gluing mechanism 600 and enter the edge stripping mechanism 700. The edge strip cutting mechanism 500 first cuts the edge strip 15 along the length direction of the edge strip 15 to form a fold 14 on the edge strip 15. Then, the gluing mechanism 600 glues the edge strip 15 to complete the coating. The glue edge strip 15 sticks to the side of the filter element 10 when the filter element 10 passes by and is transported to the edge strip mechanism 700 along the filter element. The edge strip mechanism 700 folds the edge strip 15 along the crease 14 to form a right-angle edge strip 11 and sticks the right-angle edge strip 11 to the side and bottom of the filter element 10. There is no need for users to stick the right-angle edge strip 11 to the side and bottom of the filter element 10. It has the advantages of high processing efficiency, low processing cost, high edge sticking accuracy, and good edge sticking quality of the filter element 10.

[0053] In another embodiment of the present invention, referring to Figure 3The edge strip feeding mechanism 400 includes at least one edge strip material tray 410 rotatably mounted on the frame 300. Specifically, the center of the edge strip material tray 410 is rotatably mounted on the frame 300 via a connecting shaft. The rolled edge strip is adapted to be placed in the edge strip material tray 410. The edge strip 15 in the edge strip material tray 410 sequentially passes through the edge strip cutting mechanism 500 and the gluing mechanism 600 and enters the edge strip attaching mechanism 700.

[0054] In another embodiment of the present invention, referring to Figure 3-Figure 5 The edge strip cutting mechanism 500 includes a cutting mounting frame 510 provided on the frame 300, and a first cutting support roller 520 and a first cutter 530 both provided on the cutting mounting frame 510. In a specific embodiment, the first cutting support roller 520 is vertically provided on the cutting mounting frame 510. The first cutter 530 is close to the peripheral wall of the first cutting support roller 520, and a first cutting gap 531 is formed between the first cutter 530 and the first cutting support roller 520. The first cutting gap 531 is used for the edge strip 15 to pass through. Specifically, referring to Figure 1 、 Figure 2 and Figure 5 The edge strip 15 is placed vertically and passes horizontally through the first cutting gap 531. During the horizontal transportation of the edge strip 15 along the first cutting gap 531, the first cutter 530 cuts the edge strip 15 along the length direction of the edge strip 15, so that a crease 14 is formed on the edge strip 15, so that the edge strip 15 can be folded along the crease 14 to form a right-angle edge strip 11.

[0055] It is understandable that the first cutter 530 does not cut the edge strip 15 along its length direction. The edge strips 15 on both sides of the fold 14 are connected, that is, the edge strip 15 can be folded along the fold 14 to form a right-angle edge strip 11.

[0056] Further, refer to Figure 2 and Figure 5 The first cutting support roller 520 is provided with an upper positioning ring 521 and a lower positioning ring 522. The edge strip 15 passes through the first cutting gap 531 and is located between the upper positioning ring 521 and the lower positioning ring 522, that is, the upper side and the lower side of the edge strip 15 are respectively in contact with the upper positioning ring 521 and the lower positioning ring 522, so that the edge strip 15 is positioned and conveyed between the upper positioning ring 521 and the lower positioning ring 522 to prevent the edge strip 15 from shifting, so that the first cutter 530 can accurately cut the edge strip 15 along the length direction of the edge strip 15, forming a fold 14 with consistent height position on the edge strip 15.

[0057] Among them, reference Figure 4 and Figure 5The edge strip cutting mechanism 500 further includes a first adjustment assembly 540 and a second adjustment assembly 550. The second adjustment assembly 550 is mounted on the cutting mounting frame 510, and the first adjustment assembly 540 is mounted on the second adjustment assembly 550. The first cutter 530 is mounted on the first adjustment assembly 540. The first adjustment assembly 540 is used to adjust the distance between the first cutter 530 and the first cutting support roller 520, thereby adjusting the depth of the fold 14 (incision). The second adjustment assembly 550 is used to adjust the position of the first cutter 530 on the edge strip 15, thereby adjusting the vertical position of the fold 14 (incision) on the edge strip 15.

[0058] Specifically, refer to Figure 4 and Figure 5 The first adjustment assembly 540 includes a cutting mount 541, a cutting movable base 542, a first linear guide 543, and a first drive assembly 546. The cutting mount 541 is mounted on the second adjustment assembly 550. The first linear guide 543 is horizontally mounted on the cutting mount 541. The cutting movable base 542 is slidably connected to the first linear guide 543 via a first slider. The first cutter 530 is mounted on the cutting movable base 542 and is adjacent to the peripheral wall of the first cutting support roller 520. The first drive assembly 546 is arranged on the cutting mounting seat 541 and is connected to the cutting movable seat 542 to drive the first cutter 530 to move along the first linear guide rail 543 to adjust the distance between the first cutter 530 and the first cutting support roller 520, thereby adjusting the depth of the fold 14 (incision) cut by the first cutter 530 on the edge strip 15. For edge strips 15 with different thicknesses, the distance between the first cutter 530 and the first cutting support roller 520 can also be adjusted to adapt to the cutting of edge strips 15 with different thicknesses, with high adaptability.

[0059] Furthermore, the first drive assembly 546 can be a linear module that drives the first cutter 530 to move along the first linear guide rail 543; or the first drive assembly 546 includes a first adjustment screw 544 and a first nut seat 545. The first nut seat 545 is provided on the cutting mounting seat 541, and the first adjustment screw 544 is threadedly connected to the threaded hole of the first nut seat 545. The screw end of the first adjustment screw 544 is rotatably connected to the cutting movable seat 542 via a connecting sleeve. Turning the first adjustment screw 544 drives the cutting movable seat 542 to move along the first linear guide rail 543, thereby adjusting the distance between the first cutter 530 and the first cutting support roller 520.

[0060] Specifically, refer to Figure 4 and Figure 5The second adjustment assembly 550 includes a first guide rod 551, an adjustment mounting bracket 552, and a second drive assembly 553. The first guide rod 551 is vertically mounted on the cutting mounting bracket 510, and the cutting mounting seat 541 is slidably connected to the first guide rod 551 via a first guide sleeve. The adjustment mounting bracket 552 is mounted on the cutting mounting bracket 510, and the second drive assembly 553 is mounted on the adjustment mounting bracket 552 and connected to the cutting mounting seat 541. The second drive assembly 553 is used to drive the first cutter 530 to move along the first guide rod 551 to adjust the position of the first cutter 530 on the edge strip 15, thereby adjusting the upper and lower positions of the first cutter 530 when cutting the fold 14 on the edge strip 15.

[0061] In a specific embodiment, the structure and principle of the second drive component 553 are basically consistent with the structure and principle of the first drive component. In other embodiments, the structure and principle of the second drive component 553 may also be inconsistent with the structure and principle of the first drive component, which is not limited here.

[0062] Further, refer to Figure 3 and Figure 4 The cutting frame 510 is vertically provided with two conveyor rollers 560. A conveying gap is formed between the two conveyor rollers 560, through which the edge strip 15 passes and is clamped between the peripheral walls of the two conveyor rollers 560. One of the conveyor rollers 560 is driven to rotate by a second driving member 561, which is provided on the cutting frame 510. As the conveyor roller 560 rotates, it continuously conveys the edge strip 15 forward, allowing the edge strip 15 from the edge strip feeding mechanism 400 to sequentially pass through the edge strip cutting mechanism 500 and the gluing mechanism 600 and enter the edge strip attaching mechanism 700. Specifically, the second driving member 561 is a motor, the shaft of which is fixedly connected to one end of one of the conveyor rollers 560, and the motor drives the conveyor roller 560 to rotate.

[0063] In a specific embodiment, referring to Figure 4 The edge strip cutting mechanism 500 further includes a second cutting support roller 570 and a second cutter 580, both mounted on the cutting mounting frame 510. The second cutter 580 is positioned adjacent to the peripheral wall of the second cutting support roller 570, and a second cutting gap is formed between the second cutter 580 and the second cutting support roller 570. The second cutting gap and the first cutting gap 531 allow the edge strip 15 to pass through in sequence. As the edge strip 15 is conveyed along the second cutting gap and the first cutting gap 531, the first cutter 530 and the second cutter 580 respectively cut both sides of the edge strip 15 (the front and back sides of the edge strip 15), forming a crease 14 (knife edge) of equal height on both sides of the edge strip 15. This allows the edge strip 15 to be more easily folded along the crease 14 to form a right-angled edge 11, facilitating the edge strip attachment mechanism 700 to fold the edge strip 15 along the crease 14 to form a right-angled edge 11.

[0064] In another embodiment of the present invention, referring to Figure 6 and Figure 7 The glue coating mechanism 600 includes a glue coating mounting frame 610 provided on the frame 300, and a glue coating roller 620 and a glue discharging head 630 both provided on the glue coating mounting frame 610. In a specific embodiment, the glue coating roller 620 is vertically provided on the glue coating mounting frame 610, a glue discharging channel is formed in the glue discharging head 630, and a glue outlet connected to the glue discharging channel is provided at one end of the glue discharging head 630. Preferably, the glue outlet is a long strip-shaped glue outlet, the glue outlet is close to the peripheral wall of the glue coating roller 620, and a glue coating gap 631 is formed between the glue outlet and the glue coating roller 620, and the glue coating gap 631 is used for the edge strip 15 to pass through. Specifically, referring to Figure 2 and Figure 7 The edge strip 15 is placed vertically and passes horizontally through the gluing gap 631. As the edge strip 15 is transported along the gluing gap 631, the glue outlet is used to discharge glue and apply the glue to one side surface of the edge strip 15, thereby coating the side surface of the edge strip 15 with glue. Specifically, the glue outlet channel is connected to a glue supply device (not shown) via a pipe, such as a glue supply pump, a glue supply pressure tank, or a glue supply pressure barrel. The glue is transported to the glue outlet through the glue supply device, and the glue is applied to one side surface of the edge strip 15.

[0065] Further, refer to Figure 6 and Figure 7 A guide plate 640 and a positioning plate 641 are provided on the side of the glue coating roller 620, and the guide plate 640 is located between the glue coating roller 620 and the edge strip mechanism 700. The guide plate 640 is used to guide the edge strip 15 that has been glued into the edge strip mechanism 700, and the positioning plate 641 is used to position the upper side of the edge strip 15 so that the edge strip 15 is positioned and transported along the guide plate 640 and enters the edge strip mechanism 700 to prevent the edge strip 15 from shifting, which is beneficial for the edge strip mechanism 700 to fold the edge strip 15 along the crease 14 to form a right-angle edge strip 11 and stick the right-angle edge strip 11 to the side and bottom of the filter element 10.

[0066] Further, refer to Figure 6 and Figure 7 The glue coating mounting frame 610 is provided with a guide plate 650 on the input side of the glue coating gap 631, and the guide plate 650 is provided with a guide groove 651 facing the glue coating gap 631, and one end of the guide groove 651 is close to the input side of the glue coating gap 631. The glue coating mounting frame 610 is vertically provided with an introduction rod 652 at the other end close to the guide groove 651. The edge strip 15 passing through the cutting edge strip mechanism 500 bypasses the introduction rod 652 and is introduced into the guide groove 651. The edge strip 15 is guided by the guide groove 651 so that the edge strip 15 is aligned with and passes through the glue coating gap 631, which is beneficial for the glue outlet to apply glue on one side surface of the edge strip 15.

[0067] Among them, reference Figure 7 and Figure 8 The gluing mechanism 600 further includes a third adjustment assembly 660 and a fourth adjustment assembly 670. The third adjustment assembly 660 is mounted on the gluing mounting frame 610, the fourth adjustment assembly 670 is mounted on the third adjustment assembly 660, and the gluing head 630 is mounted on the fourth adjustment assembly 670. The third adjustment assembly 660 is used to adjust the distance between the gluing head 630 and the gluing roller 620, and the fourth adjustment assembly 670 is used to adjust the height of the gluing head 630.

[0068] Further, refer to Figure 7 and Figure 8 The third adjustment assembly 660 includes an adjustment mounting seat 661, a third adjustment screw 662, a third nut 663, and a third linear guide 664. The adjustment mounting seat 661 is mounted on the gluing mounting frame 610, the third adjustment screw 662 is rotatably mounted on the adjustment mounting seat 661, and the third nut 663 is screwed to the third adjustment screw 662. The third linear guide 664 is mounted on the gluing mounting frame 610, and the fourth adjustment assembly 670 is slidably connected to the third linear guide 664 via a third slider, and the third nut 663 is fixed to the fourth adjustment assembly 670 via a nut mounting plate. Turning the third adjustment screw 662 drives the glue dispensing head 630 to move along the third linear guide 664, so that the distance between the glue dispensing head 630 and the glue coating roller 620 can adapt to gluing of edge strips 15 of different thicknesses, with high adaptability.

[0069] Specifically, refer to Figure 7 and Figure 8 The structure of the fourth adjustment component 670 is basically the same as that of the third adjustment component 660. Therefore, the way the fourth adjustment component 670 adjusts the height of the glue dispensing head 630 is the same as the way the third adjustment component 660 adjusts the distance between the glue dispensing head 630 and the glue coating roller 620.

[0070] In another embodiment of the present invention, referring to Figure 9 and Figure 11 The welt strip mechanism 700 includes a welt strip assembly 710 and a folding piece 720. The welt strip assembly 710 is arranged along the conveying direction of the filter element conveying mechanism 310, and the folding piece 720 is arranged between the welt strip assembly 710 and the gluing mechanism 600. The folding piece 720 is provided with an inclined guide groove 721. The glued edge strip 15 is guided from the gluing mechanism 600 through the inclined guide groove 721 to be folded along the fold 14 to form a right-angle edge strip 11 and enter the welt strip assembly 710. Figure 1 、 Figure 2 and Figure 11That is, the glue-coated edge strip 15 is transported from the lowest point of the inclined guide groove 721 from bottom to top along the inclined guide groove 721 and is guided by the inclined guide groove 721 to be folded 90° along the fold 14 to form a right-angled edge strip 11. The glue-coated edge strip 15 is transported to the edge strip mechanism 700 along with the filter element. The edge strip assembly 710 presses the right-angled edge strip 11 to stick to the side and bottom of the filter element 10, completing the edge of the filter element 10.

[0071] Further, refer to Figure 9 and Figure 11 The welt strip assembly 710 includes a welt conveyor belt 711 and a support strip 713. The welt conveyor belts 711 of the two cutting and gluing welt mechanisms 320 are symmetrically arranged on opposite sides of the filter element conveying mechanism 310 and arranged along the conveying direction of the filter element conveying mechanism 310. The support strips 713 of the two cutting and gluing welt mechanisms 320 are respectively located between the two welt conveyor belts 711 and the opposite sides of the two filter element conveying mechanisms 310 and arranged along the conveying direction of the filter element conveying mechanism 310. The welt conveyor belt 711 is annular, and the two ends of the welt conveyor belt 711 are respectively adapted to be mounted on the outside of two transmission wheels 712. The two transmission wheels 712 are rotatably mounted on the frame 300, and at least one of the transmission wheels 712 is driven to rotate by a first driving member. Specifically, one of the transmission wheels 712 in the two welt conveyor belts 711 is driven to rotate by a first driving member (not shown), thereby driving the two welt conveyor belts 711 to rotate synchronously with the filter element conveying mechanism 310, so that the filter element 10 and the edge strip 15 are synchronously transported in the filter element conveying mechanism 310 and the welt conveyor belt 711. Figure 1 、 Figure 2 and Figure 11 The folding member 720 is disposed between the support bar 713 and the gluing mechanism 600. During rotation, the welt conveyor belt 711 is used to press the vertical edge 12 of the right-angled edge strip 11 against the side edge of the filter element 10. The support bar 713 is used to press the horizontal edge 13 of the right-angled edge strip 11 and adhere it to the bottom of the filter element 10, thereby achieving the adhesion of the right-angled edge strip 11 to the side and bottom of the filter element 10. Specifically, the first driving member is a motor, the motor's rotating shaft is fixedly connected to the axis of one of the transmission wheels 712 in the welt conveyor belt 711, and the transmission wheel 712 is driven by the motor to rotate, resulting in a simple structure.

[0072] Among them, reference Figure 6 、 Figure 10 and Figure 11 The filter element edge-adhesion device further includes an edge-adhesion mechanism 730. The edge-adhesion mechanism 730 includes two first Z-direction transfer assemblies 731 and two edge-adhesion plates 732. The two first Z-direction transfer assemblies 731 are symmetrically arranged on the frame 300, and the two edge-adhesion plates 732 are respectively arranged on the two first Z-direction transfer assemblies 731. The two edge-adhesion plates 732 are respectively arranged corresponding to the edge-adhesion conveyor belts 711 of the two edge-adhesion strip assemblies 710. Figure 1 、 Figure 2and Figure 11 The two first Z-direction transfer assemblies 731 are used to drive the two pressure plates 732 to move downward and extend into the wave fold of the filter element 10 and fit the inner sides of its opposite side edges, limiting the outward movement of the filter element 10, so that the side edges of the filter element 10 and the vertical edges 12 of the right-angled edge strips 11 are located between the pressure plates 732 and the edge conveyor belt 711 of the edge strip assembly 710, and the side edges of the filter element 10 and the vertical edges 12 of the right-angled edge strips 11 are pressed tightly (completely fit) by the pressure plates 732 and the edge conveyor belt 711 of the edge strip assembly 710, so that the side edges of the filter element 10 and the vertical edges 12 of the right-angled edge strips 11 are firmly bonded, and the edge quality is good. After the edge pressing plate 732 has pressed a filter element 10, the two first Z-direction transfer assemblies 731 each drive the edge pressing plates 732 upward and away from the filter element 10. When the next filter element 10 moves below the edge pressing plates 732, the two first Z-direction transfer assemblies 731 then drive the edge pressing plates 732 downward and extend into the inner sides of the opposite sides of the next filter element 10, and this process repeats. Specifically, the first Z-direction transfer assembly 731 can be a pneumatic cylinder or a linear module, which drives the edge pressing plates 732 up and down, resulting in a simple structure.

[0073] It can be understood that the edge pressing plate 732 and the edge conveyor belt 711 do not over-press the side edges of the filter element 10 and the vertical edges 12 of the right-angled edge strips 11. The filter element 10 and the edge strips 15 can be moved between the edge pressing plate 732 and the edge conveyor belt 711 for transportation under the drive of the filter element conveying mechanism 310 and the edge conveyor belt 711.

[0074] Preferably, the spacing between the edge pressing piece 732 and the edge conveyor belt 711 is equal to or slightly smaller than the thickness of the side edges of the filter element 10 and the vertical edges 12 of the right-angled edge strips 11 combined, so that the edge pressing piece 732 and the edge conveyor belt 711 can better press the side edges of the filter element 10 and the vertical edges 12 of the right-angled edge strips 11 tightly and firmly.

[0075] Further, refer to Figure 10The edge pressing mechanism 730 further includes two first X-direction transfer assemblies 733 and two first Y-direction transfer assemblies 734. The two first X-direction transfer assemblies 733 are symmetrically arranged on the frame 300, one end of the two first Y-direction transfer assemblies 734 is connected and arranged on the two first X-direction transfer assemblies 733, and the two first Z-direction transfer assemblies 731 are symmetrically arranged on the two first Y-direction transfer assemblies 734. The two first X-direction transfer assemblies 733 drive the two edge pressing plates 732 to move in the X direction, the two first Y-direction transfer assemblies 734 drive the two edge pressing plates 732 to move in the Y direction, and the two first Z-direction transfer assemblies 731 drive the two edge pressing plates 732 to move in the Z direction (up and down), thereby driving the two edge pressing plates 732 to move downward and extend into the inner sides of the opposite sides of the filter element 10, or to move the two edge pressing plates 732 upward and away from the filter element 10. Specifically, the first X-axis moving assembly 733 and the first Y-axis moving assembly 734 can both be linear modules with a simple structure.

[0076] Among them, reference Figure 9 and Figure 10 , a limiting rod 740 is provided above each of the two support bars 713, and both limiting rods 740 are provided along the conveying direction of the filter element conveying mechanism 310. Figure 1 and Figure 9 The two limiting rods 740 are used to press the two opposite sides of the upper end of the filter element 10 respectively, so that the bottom of the filter element 10 is close to the filter element conveying mechanism 310. During the synchronous conveying of the filter element 10 and the side strip 15, the support bar 713 presses the horizontal edge 13 of the right-angle side strip 11. The limiting rods 740 and the support bar 713 press the bottom of the filter element 10 and the horizontal edge 13 of the right-angle side strip 11 to stick tightly (completely fit), so that the bottom of the filter element 10 and the horizontal edge 13 of the right-angle side strip 11 are firmly bonded, and the edge quality is good.

[0077] Further, refer to Figure 9 The two limiting rods 740 are respectively mounted on two fifth adjustment assemblies 741. The fifth adjustment assemblies 741 are used to adjust the distance between the limiting rods 740 and the support bar 713 to accommodate filter cartridges 10 of different heights. Specifically, the structure of the fifth adjustment assembly 741 is substantially identical to that of the third adjustment assembly 660. Therefore, the fifth adjustment assembly 741 adjusts the distance between the limiting rods 740 and the support bar 713 in the same manner as the third adjustment assembly 660 adjusts the distance between the dispensing head 630 and the coating roller 620.

[0078] In another embodiment of the present invention, referring to Figure 3 and Figure 6 The filter element edge weaving device further includes a strip cutting mechanism 900. The cutting and gluing edge weaving mechanism 320 and the strip cutting mechanism 900 are sequentially arranged along the conveying direction of the filter element conveying mechanism 310. The strip cutting mechanism 900 is used to cut the two right-angled strips 11 between two adjacent filter elements 10.

[0079] Further, refer to Figure 3 and Figure 12 The edge strip cutting mechanism 900 includes a filter element conveying assembly 910, two second Z-direction transfer assemblies 920, and two cutting assemblies 930. The filter element conveying assembly 910 is mounted on the frame 300. The conveying start end of the filter element conveying assembly 910 connects to the conveying end end of the filter element conveying mechanism 310, and is used to carry and transport the filter element 10 after the edge strips are attached. The two second Z-direction transfer assemblies 920 are symmetrically mounted on the frame 300, and the two cutting assemblies 930 are respectively mounted on the two second Z-direction transfer assemblies 920. The two second Z-direction transfer assemblies 920 are used to respectively drive the two cutting assemblies 930 to move up and down. The filter element conveying assembly 910 sequentially transports multiple filter elements 10 connected in series by right-angled edge strips 11 to the cutting assemblies 930. When the two cutting assemblies 930 move downward, they are used to cut the two right-angled edge strips 11 between two adjacent filter elements 10, roughly shearing the right-angled edge strips 11 to obtain a single filter element 10 with the edge strips attached. The ends of the right-angled strips 11 will extend beyond the sides of the filter element 10, allowing for subsequent precision cutting of the excessively long right-angled strips 11 on the sides of the filter element 10. It is understood that precision cutting can be performed manually. Specifically, the second Z-axis transfer assembly 920 can be a pneumatic cylinder or linear module, which drives the cutting assembly 930 up and down, resulting in a simple structure. Specifically, the cutting assembly 930 can be an electric shear or a power saw, etc., which is not limited here.

[0080] Further, refer to Figure 3 and Figure 12 The edge strip cutting mechanism 900 includes a second X-direction transfer assembly 940 and two second Y-direction transfer assemblies 950. The second X-direction transfer assembly 940 is arranged on the frame 300, the two second Y-direction transfer assemblies 950 are symmetrically arranged on the second X-direction transfer assembly 940, and the two second Z-direction transfer assemblies 920 are respectively arranged on the two second Y-direction transfer assemblies 950. The cutting assembly 930 is driven to move in the X direction by the second X-direction transfer assembly 940, the cutting assembly 930 is driven to move in the Y direction by the second Y-direction transfer assembly 950, and the cutting assembly 930 is driven to move in the Z direction (up and down) by the second Z-direction transfer assembly 920, so as to facilitate the cutting assembly 930 to cut the two right-angle edge strips 11 between two adjacent filter elements 10. Specifically, the second X-direction transfer assembly 940 and the second Y-direction transfer assembly 950 can both be linear modules with a simple structure.

[0081] Among them, reference Figure 3 and Figure 12The filter element conveying mechanism 310 and the filter element conveying assembly 910 are primarily used to carry and convey the filter element 10. For example, the filter element conveying mechanism 310 and the filter element conveying assembly 910 can be an assembly line in the form of a belt or plate chain, which is widely used in various automated equipment. When in operation, the filter element conveying mechanism 310 and the filter element conveying assembly 910 drive the filter element 10 to continuously move forward.

[0082] In another embodiment of the present invention, referring to Figure 3 and Figure 6 The filter element edging device further includes an air drying mechanism 800. The air drying mechanism 800 is disposed between the cutting and gluing edging mechanism 320 and the edge strip cutting mechanism 900 and is located next to the filter element conveying mechanism 310. The air drying mechanism 800 is used to dry the glue between the filter element 10 and the right-angle edge strip 11.

[0083] Further, refer to Figure 3 and Figure 9 The air-drying mechanism 800 includes two air-drying plates 810 and two air-drying boxes 820. The two air-drying plates 810 are symmetrically arranged on opposite sides of the filter element conveying mechanism 310. The air-drying plates 810 are provided with an air-drying port 811 facing the filter element conveying mechanism 310. The air-drying plates 810 are provided with an interface 812 connected to the air-drying port 811. The interface 812 is connected to the air-drying box 820 via a connecting pipe. When the air-drying box 820 is in operation, air is supplied to the air-drying port 811. The air blown out by the air-drying port 811 is used to air-dry the glue between the filter element 10 and the right-angled side strip 11, causing the glue to solidify quickly and quickly adhere the right-angled side strip 11 to the filter element 10. This prevents the right-angled side strip 11 from falling off the filter element 10 when the side strip cutting mechanism 900 cuts the right-angled side strip 11 between two adjacent filter elements 10.

[0084] The rest of this embodiment is the same as that of the first embodiment. The features not explained in this embodiment are all based on the explanations of the first embodiment and will not be described in detail here.

[0085] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, its architecture can be flexible and varied, and a series of products can be derived. Simply making a few simple deductions or substitutions should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
