Description

Technical Field

[0001] The invention belongs to the technical field of filter element production, and in particular relates to filter element production equipment. 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 the attachment of right-angled edge strips 11, the right-angled edge strips 11 are attached 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 edge strips 11 to filter elements 10. The filter elements 10 can only be edge-attached and edge-trimmed by personnel who first fold the edge strips into right-angled edge strips 11, then attach the right-angled edge strips 11 to the sides and bottom of the filter element 10, and finally, by personnel who cut off the excessively long right-angled edge strips 11 on the sides of the filter element 10. However, the above-mentioned method of manually attaching and cutting right-angled edge strips not only has low processing efficiency and high processing costs, but also has low edge-attaching precision, which easily produces defective products, and poor edge-cutting safety. Summary of the Invention

[0004] The purpose of the present invention is to provide a filter element production equipment, aiming to solve the technical problems in the prior art of using personnel to stick and cut right-angled edge strips, which not only has low processing efficiency but also high processing costs.

[0005] To achieve the above-mentioned purpose, an embodiment of the present invention provides a filter element production device, comprising a filter element edge attaching device and a filter element edge trimming device;

[0006] The filter element edging device includes a frame, a filter element conveying mechanism and two cutting and gluing edging mechanisms; the filter element conveying mechanism is arranged on the frame and is used to convey the filter element, and the two cutting and gluing edging mechanisms are symmetrically arranged on opposite sides of the filter element conveying mechanism; the cutting and gluing edging mechanism includes a side strip feeding mechanism, a cutting side strip mechanism, a gluing mechanism and a side strip weaving mechanism, all of which are arranged on the frame; the side strip feeding mechanism is used to load side strips, and the side strips of the side strip feeding mechanism pass through the cutting side strip mechanism and the gluing mechanism in turn and enter the side strip weaving mechanism; the cutting side strip mechanism is used to cut the side strips along the length direction of the side strips so that a fold is formed on the side strips; the gluing mechanism is used to glue the side strips, and the side strip weaving mechanism is located next to the filter element conveying mechanism and is used to fold the side strips along the fold to form right-angled side strips and stick the right-angled side strips to the side and bottom of the filter element;

[0007] The filter element trimming device includes a bracket, a filter element transplanting mechanism and four groups of filter element trimming mechanisms; the filter element trimming mechanism is arranged on the bracket, the filter element transplanting mechanism is arranged on the bracket and is used to transplant the completed filter element to the four groups of filter element trimming mechanisms, and the four groups of filter element trimming mechanisms are respectively used to cut the excess right-angle strips at the four corners of the filter element.

[0008] Compared with the prior art, the one or more technical solutions in the filter element production equipment provided by the embodiments of the present invention have at least one of the following technical effects:

[0009] 1. During operation, multiple filter elements to be pasted with edge strips are conveyed to the edge strip pasting mechanism in turn along the filter element conveying mechanism, and the edge strips of the edge strip feeding mechanism pass through the edge strip cutting mechanism and the gluing mechanism in turn and enter the edge strip pasting mechanism, first cutting the edge strips along the length direction of the edge strips by the edge strip cutting mechanism to form a crease on the edge strips; then gluing the edge strips by the gluing mechanism, and the edge strips after gluing are adhered to the side of the filter element when the filter element passes through and are conveyed to the edge strip pasting mechanism along the filter element, and the edge strip pasting mechanism folds the edge strips along the crease to form right-angled edge strips and pastes the right-angled edge strips to the side and bottom of the filter element; then the filter element transplanting mechanism transplants the filter element with completed edge pasting to the four sets of filter element trimming mechanisms, which are respectively used to cut the excess right-angled edge strips at the four corners of the filter element, without the need for personnel to paste and cut right-angled edge strips, which not only has high processing efficiency and low processing cost, but also has high edge pasting and trimming precision, good filter element production quality, and good safety.

[0010] 2. Press the two limit rods downward against the two opposite sides of the upper end of the filter element, so that the bottom of the filter element is close to the filter element conveying mechanism, and the two pressure plates move downward and extend into the wave fold of the filter element and fit the inner sides of the opposite sides to limit the outward movement of the filter element. During the synchronous conveying of the filter element and the edge strips, the glue-coated edge strips are guided by the inclined guide groove of the folding piece and folded at 90 degrees along the crease to form a right-angled edge strip. The filter element and the edge strips are fit together while being conveyed, so that the side edges of the filter element and the vertical edges of the right-angled edge strips are tightly adhered (completely fitted), and the bottom of the filter element and the horizontal edges of the right-angled edge strips are tightly adhered (completely fitted), and the edge quality is good.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0031] In one embodiment of the present invention, referring to Figures 1-18 , provides a filter element production equipment, including a filter element edge-attaching device 30 and a filter element edge-cutting device 20.

[0032] Among them, reference Figure 1-Figure 4 The filter element wedging device 30 includes a frame 300, a filter element conveying mechanism 310, and two cutting, gluing, and wedging mechanisms 320. The filter element conveying mechanism 310 is mounted on the frame 300 and is used to convey the filter element 10. The two cutting, gluing, and wedging mechanisms 320 are symmetrically located on opposite sides of the filter element conveying mechanism 310. The cutting, gluing, and wedging mechanism 320 includes a strip feeding mechanism 400, a strip cutting mechanism 500, a gluing mechanism 600, and a wedging mechanism 700, all of which are mounted 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 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 apply glue to the edge strip 15 , and the edge strip pasting mechanism 700 is located next to the filter element conveying mechanism 310 and is used to fold the edge strip 15 along the fold 14 to form a right-angled edge strip 11 and paste the right-angled edge strip 11 to the side and bottom of the filter element 10 .

[0033] Among them, reference Figure 1 、 Figure 3 and Figure 14 The filter element trimming device 20 includes a support 100, a filter element transfer mechanism 130a, and four sets of filter element trimming mechanisms 200. The filter element trimming mechanism 200 is mounted on the support 100. The filter element transfer mechanism 130a is mounted on the support 100 and is used to transfer the filter element 10 after the edge is attached to the four sets of filter element trimming mechanisms 200. The four sets of filter element trimming mechanisms 200 are used to trim the excess right-angled edge strips 11 at the four corners of the filter element 10.

[0034] Reference Figure 1 、 Figure 3 and Figure 14During operation, multiple filter elements 10 to be edge-stripped 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 its length, so that a fold 14 is formed on the edge strip 15. Then, the gluing mechanism 600 glues the edge strip 15. The glued edge strip 15 is adhered to the side of the filter element 10 when the filter element 10 passes by and is conveyed to the edge stripping machine along with the filter element 10. Structure 700, the edge strip mechanism 700 folds the edge strip 10 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; then the filter element transplanting mechanism 130a transplants the filter element 10 with the completed edge patching to the four sets of filter element trimming mechanisms 200, and the four sets of filter element trimming mechanisms 200 are used to cut the excess right-angle edge strips 11 at the four corners of the filter element 10 respectively, without the need for users to stick the right-angle edge strips 11 and cut the right-angle edge strips 11, not only the processing efficiency is high and the processing cost is low, but also the edge patching and trimming precision is high, the filter element production quality is good, and the safety is good.

[0035] Among them, reference Figure 3 and Figure 4 The 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.

[0036] In another embodiment of the present invention, referring to Figure 4-Figure 6 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 5The side strip 15 is placed vertically and passes horizontally through the first cutting gap 531. During the horizontal conveyance of the side strip 15 along the first cutting gap 531, the first cutter 530 cuts the side strip 15 along its length, forming a fold 14 on the side strip 15, so that the side strip 15 can be folded along the fold 14 to form a right-angled side strip 11. It is understood that the first cutter 530 does not cut the side strip 15 along its length. The side strips 15 on both sides of the fold 14 are connected, that is, the side strip 15 can be folded along the fold 14 to form a right-angled side strip 11.

[0037] Further, refer to Figure 3 and Figure 6 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.

[0038] Among them, reference Figure 5 and Figure 6 The 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.

[0039] Specifically, refer to Figure 5 and Figure 6The 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.

[0040] 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.

[0041] Specifically, refer to Figure 5 and Figure 6 The 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 fold 14 cut by the first cutter 530 on the edge strip 15. In a specific embodiment, the structure and principle of the second drive assembly 553 are basically the same as those of the first drive assembly. In other embodiments, the structure and principle of the second drive assembly 553 may also be different from those of the first drive assembly, which is not limited here.

[0042] Further, refer to Figure 4 and Figure 5 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.

[0043] In a specific embodiment, referring to Figure 5 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.

[0044] In another embodiment of the present invention, referring to Figure 7 and Figure 8 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 7The 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.

[0045] Further, refer to Figure 7 and Figure 8 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.

[0046] Further, refer to Figure 7 and Figure 8 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.

[0047] Among them, reference Figure 8 and Figure 9 The glue coating mechanism 600 further includes a third adjustment component 660 and a fourth adjustment component 670 . The third adjustment component 660 is disposed on the glue coating mounting frame 610 , the fourth adjustment component 670 is disposed on the third adjustment component 660 , and the glue dispensing head 630 is disposed on the fourth adjustment component 670 .

[0048] Further, refer to Figure 8 and Figure 9The 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.

[0049] Specifically, refer to Figure 8 and Figure 9 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.

[0050] In another embodiment of the present invention, referring to Figure 10 and Figure 12 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 11 That 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.

[0051] Further, refer to Figure 10 and Figure 12The 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.

[0052] Among them, reference Figure 7 、 Figure 11 and Figure 12 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 2 and Figure 11The 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.

[0053] 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.

[0054] 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.

[0055] Further, refer to Figure 11The 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.

[0056] Among them, reference Figure 10 and Figure 11 , 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.

[0057] Further, refer to Figure 10 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.

[0058] In another embodiment of the present invention, referring to Figure 4 and Figure 7 The filter element edge pasting device also includes a strip cutting mechanism 900. The cutting and gluing edge pasting mechanism 320 and the strip cutting mechanism 900 are sequentially arranged along the conveying direction of the filter element conveying mechanism 310. Figure 4 and Figure 13The 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 be too long and extend beyond the sides of the filter element 10. This allows the filter element trimming device to subsequently fine-trim the excessive right-angled strips 11 on the sides of the filter element 10, ensuring that the cuts of the right-angled strips 11 are smooth and flush with the sidewalls of the filter element 10. Specifically, the second Z-axis transfer assembly 920 can be a cylinder or a 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 an electric saw, etc., which is not limited here.

[0059] Further, refer to Figure 4 and Figure 13 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.

[0060] In another embodiment of the present invention, referring to Figure 4 and Figure 7 The filter element edge pasting device also includes an air drying mechanism 800. The air drying mechanism 800 is provided between the cutting and gluing edge pasting mechanism 320 and the edge strip cutting mechanism 900 and is located beside the filter element conveying mechanism 310. Figure 4 and Figure 10The 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.

[0061] In another embodiment of the present invention, referring to Figure 14 、 Figure 16 and Figure 17 The filter element trimming mechanism 200 includes a first mounting seat 210, a fixed blade 220, a movable blade 230, and a third driving member 240. The first mounting seat 210 is mounted on the bracket 100, the fixed blade 220 is mounted on the first mounting seat 210, and the movable blade 230 is movably mounted on the first mounting seat 210 and disposed opposite the fixed blade 220, with a shearing position 250 formed between the movable blade 230 and the fixed blade 220. The movable blade 230 is provided with a first blade edge 231 and a second blade edge 232 connected to each other, and the angle a between the first blade edge 231 and the second blade edge 232 is an obtuse angle. The third driving member 240 is arranged on the first mounting seat 210, and the third driving member 240 is used to drive the movable knife 230 to move back and forth, and is used to cut the vertical edge 12 of the right-angled edge strip 11 of the filter element 10 when the first blade 231 cooperates with the fixed knife 220, and is used to cut the horizontal edge 13 of the right-angled edge strip 11 of the filter element 10 when the second blade 232 cooperates with the fixed knife 220.

[0062] Specifically, refer to Figure 3 、 Figure 13 、 Figure 14 and Figure 17The single filter element 10 obtained by cutting the right-angled edge strips 11 by the edge strip cutting mechanism 900 is transported to the side of the filter element transfer mechanism 130a by the filter element transfer assembly 910, and then the filter element transfer mechanism 130a transfers the filter element 10 with the completed edge strips to the four sets of filter element trimming mechanisms 200, so that the redundant right-angled edge strips 11 at the four corners of the filter element 10 are respectively placed in the shearing positions 250 of the four sets of filter element trimming mechanisms 200, and then each set of filter element trimming is The third drive member 240 of the mechanism 200 drives the movable blade 230 toward the fixed blade 220. The first blade 231 cooperates with the fixed blade 220 to shear the vertical edge 12 of the right-angled edge strip 11 of the filter element 10, and the second blade 232 cooperates with the fixed blade 220 to shear the horizontal edge 13 of the right-angled edge strip 11 of the filter element 10. Similar to the shearing method of scissors, the cut of the right-angled edge strip 11 is smooth and flush with the side wall of the filter element 10, ensuring the quality of the trimming of the filter element 10. Therefore, the four sets of filter element trimming mechanisms 200 respectively trim the excess right-angled edge strips 11 at the four corners of the filter element 10, completing the trimming of the excess right-angled edge strips 11 at the four corners of the filter element 10 at one time, which has high trimming efficiency, low processing cost, and good safety.

[0063] Further, refer to Figure 3 、 Figure 13 and Figure 14 A filter element transfer mechanism 960 is provided between the conveying end of the filter element conveying assembly 910 and the filter element transplanting mechanism 130a. The filter element transfer mechanism 960 transports a single filter element 10 that has been pasted to the side of the filter element transplanting mechanism 130a, making it easier for the filter element transplanting mechanism 130a to transplant the filter element 10 that has been pasted to the four sets of filter element trimming mechanisms 200. Figure 1 、 Figure 3 and Figure 12 The filter element conveying mechanism 310, filter element conveying assembly 910, and filter element transfer mechanism 960 are primarily used to carry and transport the filter element 10. For example, the filter element conveying mechanism 310, filter element conveying assembly 910, and filter element transfer mechanism 960 can all be in the form of a belt or plate chain assembly, which are widely used in various automated equipment. When in operation, the filter element conveying mechanism 310, filter element conveying assembly 910, and filter element transfer mechanism 960 drive the filter element 10 to continuously move forward.

[0064] Further, refer to Figure 16 and Figure 17The fixed blade 220 is provided with a connected vertical blade 221 and a horizontal blade 222. When the first blade 231 cooperates with the vertical blade 221, it is used to cut the vertical edge 12 of the right-angled edge strip 11 of the filter element 10. When the second blade 232 cooperates with the horizontal blade 222, it is used to cut the horizontal edge 13 of the right-angled edge strip 11 of the filter element 10. The first blade 231 cooperates with the vertical blade 221, and the second blade 232 cooperates with the horizontal blade 222 to respectively cut the vertical edge 12 and horizontal edge 13 of the right-angled edge strip 11 of the filter element 10, similar to the cutting method of scissors. This ensures a smooth cut on the right-angled edge strip 11 and ensures the quality of the cut edge of the filter element 10.

[0065] In a specific embodiment, referring to Figure 16 and Figure 17 The first blade 231 and the second blade 232 are both inclined, and the angle b between the first blade 231 and the vertical blade 221 is an acute angle. When the third driving member 240 drives the first blade 231 toward the vertical blade 221, it will first cut the vertical edge 12 of the right-angled side strip 11 from the top along the vertical edge 12 downward, similar to using scissors to cut from the top to the bottom of the vertical edge 12, so that the cut of the vertical edge 12 is smooth. The angle c between the second blade 232 and the horizontal blade 222 is an acute angle. When the third driving member 240 drives the second blade 232 toward the horizontal blade 222, it will first cut the horizontal edge 13 from one end of the horizontal edge 13 of the right-angled side strip 11 along the horizontal edge 13 to the other end, similar to using scissors to cut from one end of the horizontal edge 13 to the other end, so that the cut of the horizontal edge 13 is smooth.

[0066] Preferably, refer to Figure 16 and Figure 17 The included angle b between the first blade 231 and the vertical blade 221 is ≥ 0° and < 45°. Therefore, when the first blade 231 contacts and shears the vertical side 12 of the right-angled side strip 11, the horizontal component of the force acting on the vertical side 12 is greater than the vertical component, which is conducive to shearing the vertical side 12. The included angle c between the second blade 232 and the horizontal blade 222 is greater than 0° and < 45°. Therefore, when the second blade 232 contacts and shears the horizontal side 13 of the right-angled side strip 11, the vertical component of the force acting on the horizontal side 13 is greater than the horizontal component, which is conducive to shearing the horizontal side 13.

[0067] Further, refer to Figure 16 and Figure 17, the filter element trimming mechanism 200 also includes a pushing assembly 260. The pushing assembly 260 includes a fourth driving member 261 and a pushing plate 262. The fourth driving member 261 is arranged on the first mounting seat 210, and the pushing plate 262 is arranged on the fourth driving member 261. The pushing plate 262 is located next to the fixed knife 220. The fourth driving member 261 drives the pushing plate 262 to move, which is used to push off the extra right-angled edge strips 11 that have been cut off, prevent the right-angled edge strips 11 that have been cut off from adhering to the fixed knife 220, and ensure that the filter element trimming mechanism 200 stably shears the right-angled edge strips 11 of the filter element 10. Specifically, the fourth driving member 261 is a second cylinder, and the telescopic rod of the second cylinder is connected to the pushing plate 262. The pushing plate 262 is driven to reciprocate by the telescopic movement of the second cylinder, thereby being used to push off the extra right-angled edge strips 11 that have been cut off, and the structure is simple.

[0068] Further, refer to Figure 16 and Figure 17 The first mounting base 210 is provided with at least one first linear slide 211, and a first mounting frame 212 is slidably connected to the first linear slide 211 via at least one first sliding block. A movable blade 230 is disposed on the first mounting frame 212. A third driving member 240 is connected to the first mounting frame 212 and is used to drive the movable blade 230 to reciprocate along the first linear slide 211, ensuring smooth movement of the movable blade 230 for precise cutting of the right-angled edge strip 11. Specifically, the third driving member 240 is a first pneumatic cylinder, the telescopic rod of which is connected to the first mounting frame 212. The telescopic movement of the first cylinder drives the first mounting frame 212 to reciprocate along the first linear slide 211, thereby driving the movable blade 230 to reciprocate along the first linear slide 211, resulting in a simple structure.

[0069] In another embodiment of the present invention, referring to Figure 14 and Figure 15 The filter element trimming mechanism 200 further includes a first X-axis transfer mechanism 110 mounted on the bracket 100, and four sets of first Y-axis transfer mechanisms 120 mounted on the first X-axis transfer mechanism 110. The four sets of filter element trimming mechanisms 200 are respectively mounted on the four sets of first Y-axis transfer mechanisms 120. The first X-axis transfer mechanism 110 and the four sets of first Y-axis transfer mechanisms 120 drive the four sets of filter element trimming mechanisms 200 to move, thereby adjusting the spacing between two adjacent sets of filter element trimming mechanisms 200 to accommodate filter elements 10 of different sizes, thus providing extremely high practicality.

[0070] In a specific embodiment, referring to Figure 14 and Figure 15The first X-axis transfer mechanism 110 includes two second linear guide rails 111, a first screw rod 112, a second screw rod 113, two first X-axis transfer plates 114, and a first motor 115. The two second linear guide rails 111 are symmetrically arranged on the bracket 100, and the two first X-axis transfer plates 114 are slidably connected to the two second linear guide rails 111 via a plurality of second sliding blocks. One end of the first screw rod 112 is fixedly connected to one end of the second screw rod 113, and the other end of the first screw rod 112 and the other end of the second screw rod 113 are respectively rotatably connected to the bracket 100 via a bearing seat. The screw threads of the first screw rod 112 and the second screw rod 113 have opposite spiral directions. The first screw rod 112 and the second screw rod 113 are both connected to screw nuts, and the two screw nuts are respectively fixedly connected to the two first X-axis transfer plates 114. Two sets of first Y-axis transfer mechanisms 120 are installed on each first X-axis transfer plate 114. The first motor 115 is installed on the bracket 100. The rotating shaft of the first motor 115 is fixedly connected to one end of the first screw rod 112. The first motor 115 drives the first screw rod 112 and the second screw rod 113 to rotate, driving the two first X-direction moving plates 114 to move closer to or away from each other, thereby driving one or two groups of filter element trimming mechanisms 200 and the other two groups of filter element trimming mechanisms 200 to move closer to or away from each other, thereby realizing spacing adjustment.

[0071] In a specific embodiment, referring to Figure 14 and Figure 15 The first Y-direction transfer mechanism 120 is a first linear module. The first mounting seat 210 of each filter element trimming mechanism 200 is fixedly mounted on a moving block of the first linear module. The filter element trimming mechanism 200 is driven to move along the Y-direction by the first linear module, thereby adjusting the distance between the two groups of filter element trimming mechanisms 200 located on the first X-direction transfer plate 114.

[0072] In another embodiment of the present invention, referring to Figure 14 and Figure 18The filter element transfer mechanism 130a includes a second Y-axis transfer mechanism 130 disposed on the bracket 100, a Z-axis transfer mechanism 140 disposed on the second Y-axis transfer mechanism 130, a connecting frame 150 disposed on the Z-axis transfer mechanism 140, and a loading mechanism 160 disposed on the connecting frame 150, or a loading mechanism 160 and a unloading mechanism 170 disposed alternately on the connecting frame 150. The loading mechanism 160 is used to clamp the filter element 10 that has been finished with the edge fitting. The second Y-axis transfer mechanism 130 and the Z-axis transfer mechanism 140 are used to drive the loading mechanism 160 to move and transfer the finished filter element 10 to between the four sets of filter element trimming mechanisms 200. This eliminates the need for human loading (filter element 10), greatly improving production efficiency and reducing processing costs. Among them, the unloading mechanism 170 is used to clamp the filter element 10 with completed trimming, and the second Y-axis transfer mechanism 130 and the Z-axis transfer mechanism 140 are used to drive the unloading mechanism 170 to move to move the filter element 10 with completed trimming out of the four groups of filter element trimming mechanisms 200. There is no need for personnel to unload the material (filter element 10), which greatly improves production efficiency and reduces processing costs.

[0073] Specifically, refer to Figure 14 and Figure 18 The second Y-direction transfer mechanism 130 is a second linear module, and the Z-direction transfer mechanism 140 is installed on the moving block of the second linear module. The second linear module drives the Z-direction transfer mechanism 140 to move in the Y direction, thereby driving the loading mechanism 160 and the unloading mechanism 170 to move in the Y direction. The Z-direction transfer mechanism 140 includes a Z-direction cylinder 141 and a second guide rod 142. The Z-direction cylinder 141 is installed on the moving block of the second linear module, and the connecting frame 150 is fixed on the driving rod of the Z-direction cylinder 141. The loading mechanism 160 and the unloading mechanism 170 are driven to move in the Z direction by the Z-direction cylinder 141. The lower end of the second guide rod 142 is fixedly connected to the connecting frame 150, and the second guide rod 142 is slidably connected to the moving block of the second linear module through the second guide sleeve 143, so that the connecting frame 150 can move stably in the Z direction, thereby causing the loading mechanism 160 and the unloading mechanism 170 to move stably in the Z direction.

[0074] Further, refer to Figure 14 and Figure 18The loading mechanism 160 includes a third X-axis transfer assembly 161 and two clamping plates 162. The third X-axis transfer assembly 161 is disposed on the connecting frame 150, and the two clamping plates 162 are symmetrically disposed on the third X-axis transfer assembly 161. The third X-axis transfer assembly 161 is used to drive the two clamping plates 162 toward or away from each other to clamp or release the filter element 10 that has been finished fitting. Specifically, the structure of the third X-axis transfer assembly 161 is consistent with that of the first X-axis transfer mechanism 110. Therefore, the principle by which the third X-axis transfer assembly 161 drives the two clamping plates 162 toward or away from each other is consistent with the principle by which the first X-axis transfer mechanism 110 drives the two first X-axis transfer plates 114 toward or away from each other.

[0075] Specifically, refer to Figure 14 and Figure 18 The structure of the unloading mechanism 170 is basically the same as that of the loading mechanism 160, or the unloading mechanism 170 uses a finger cylinder to drive the two clamping plates 162 to move closer to or away from each other.

[0076] 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.
