Description

Technical Field

[0001] This utility model relates to the field of air filter edge bonding technology, and in particular to a rotary double-sided edge bonding machine. Background Technology

[0002] In both automotive and residential air conditioning systems, the air filter is crucial. To maximize the filtration area, air conditioning filters are typically made by folding filter paper multiple times and then shaping it. For strength considerations, strips are usually attached to the two or four sides perpendicular to the folds in the paper filter. The two sides perpendicular to the folds are called the long sides, and the other two are called the short sides.

[0003] One issue is that during the short-side application process, the filter element's short side is prone to shifting due to pressure from the application assembly, making alignment difficult. Furthermore, existing technologies sometimes involve manual application of the short-side edge-applying process, which struggles to ensure surface alignment and can lead to angular misalignment, increasing the defect rate and affecting product consistency. Semi-automated production methods exist, where the filter element is manually placed at the application station, the application machine applies the edge strip, and then the element is manually removed. While this method can guarantee a high yield, its efficiency is too low. Therefore, improvements to existing technologies are necessary. Utility Model Content

[0004] Therefore, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a rotary double-sided edge-applying machine.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rotary double-sided edge-sealing machine includes a machine base, and further includes:

[0007] The machine tool is equipped with a rotary filter cartridge feeding device and two edge-attaching strip devices.

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention.

[0030] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this utility model.

[0031] Please see Figures 1 to 6 This embodiment provides a rotary table type double-sided edge-sealing machine, including a machine base and a rotary filter element feeding device 1 and two edge-sealing strip devices disposed on the machine base. The rotary filter element feeding device is used to rotate and feed the filter element to the edge-sealing station, and the two edge-sealing strip devices are respectively used to attach the edge strip to one side and the other side of the filter element located at the edge-sealing station.

[0032] The edge strip attaching device includes a feeding mechanism 2 for placing edge strip raw materials (edge ​​strip rolls), a feeding mechanism 3 for feeding edge strips, a pre-cutting mechanism 4 for making cuts on the edge strips and disposed between the feeding mechanism 2 and the feeding mechanism 3, a gluing mechanism 5 for applying glue to the edge strips fed by the feeding mechanism 3, an edge strip fixture 6 for loading the glued edge strips, a cutting mechanism 7 disposed between the gluing mechanism 5 and the edge strip fixture 6, a flipping drive mechanism 8 for driving the edge strip fixture 6 to flip, and a transverse attaching mechanism 9 for driving the edge strip fixture 6 to attach the edge strips to the filter element.

[0033] Under normal conditions, the edge strip fixture 6 is in a horizontal position. When in use, the rotating filter element feeding device 1 transports the filter element to the edge-attaching station. The two edge-attaching devices attach edge strips to both sides of the filter element simultaneously. Specifically, when attaching the edge strip, one end of the edge strip roll on the feeding mechanism 2 is taken out, and the free end of the edge strip is passed through the feeding mechanism 3. The feeding mechanism 3 drives the edge strip to move continuously. The pre-cutting mechanism 4, located between the feeding mechanism 3 and the feeding mechanism 2, first cuts the edge strip, so that the edge strip has cut marks, which facilitates subsequent processing. When the edge strip passes through the gluing mechanism 5, the gluing mechanism 5 applies glue to the edge strip. The gluing mechanism 5 intermittently applies glue to the edge strip being conveyed. The glued edge strip enters the edge strip fixture 6. When the edge strip on the edge strip fixture 6 reaches the set length, the cutting mechanism 7 cuts the edge strip, separating the glued edge strip from the edge strip raw material. The flipping drive mechanism 8 drives the edge strip fixture 6 to flip 90°, that is, drives the edge strip fixture 6 to a vertical state. The edge strip fixture 6 drives the edge strip to flip 90°. The transverse strip attaching mechanism 9 drives the flipped edge strip fixture 6 to approach the rotating edge strip. The filter element on the filter element feeding device 1 moves, and the edge strip coated with glue on the edge strip fixture 6 is attached to one side of the filter element (another edge strip attaching device attaches the edge strip to the other side of the filter element), thus realizing the edge attaching of the filter element. This edge attaching machine has a simple structure and reasonable design, automatically realizing the feeding of the filter element, the feeding of the edge strip, the application of glue to the edge strip, and the cutting of the edge strip. Moreover, by using two edge strip attaching devices to attach the edge strip to both sides of the filter element at the same time, the efficiency of filter element edge attaching is improved, the labor intensity of operators is reduced, and the edge attaching accuracy of the filter element is high, ensuring the quality of the filter element. Furthermore, the filter element is transported to the edge attaching station by the rotary filter element feeding device 1, eliminating the manual part and improving efficiency. Subsequent processes can use robotic arms or other devices to place the edge-attached filter element to the required station later.

[0034] The rotary filter cartridge feeding device 1 described in this embodiment includes a turntable 11, a rotating mechanism 12, a filter cartridge fixture 13, a filter cartridge lifting mechanism 14, and a heat dissipation device 15.

[0035] The turntable 11 is rotatably mounted on the machine base. Multiple filter element fixtures 13 are arranged on the turntable 11 along the circumferential direction. The rotating mechanism 12 is used to drive the turntable 11 to rotate. The turntable 11 drives the filter element fixtures 13 from the filter element placement station to the edge-fitting station and the heat dissipation station in sequence. The filter element lifting mechanism 14 is used to drive the filter element fixtures 13 to lift when they are in the edge-fitting station. The heat dissipation device 15 is fixedly mounted on the machine base and is used to dissipate heat from the filter element located in the heat dissipation station after the edge strip has been attached. This setup allows filter elements to enter the edge-applying station in an orderly manner for edge-applying. At the filter element placement station, the filter element is placed into the filter element fixture 13. The rotating mechanism 12 rotates the fixture 13 to the edge-applying station. The filter element lifting mechanism 14 lifts the fixture 13, and the edge-applying device applies the edge-applying strip. Once edge-applying is complete, the lifting mechanism 14 lowers, the fixture 13 returns to its original position, and the turntable 11 rotates 90°. The edge-applied filter element then cools at the heat dissipation station. This cycle repeats. The filter element lifting mechanism 14 can be a lifting cylinder, the rotating mechanism 12 can be a motor connected to a cam divider, the output end of which rotates the turntable 11, and the heat dissipation device 15 can be a cooling fan.

[0036] like Figure 2 As shown, the feeding mechanism 2 includes a feeding frame 21 mounted on the machine base and a feeding disc rotatably mounted on the feeding frame 21. The feeding disc includes a rotating roller 22, a first disc body 23 and a second disc body 24. The rotating roller 22 is rotatably connected to the feeding frame 21. The first disc body 23 and the second disc body 24 are both mounted on the rotating roller 22. A strip roll clamping space 25 is formed between the first disc body 23 and the second disc body 24. The second disc body 24 can be connected to the rotating roller 22 by a hand-tightening screw.

[0037] In actual use, turn the hand screw of the second disc 24 to open it, place the edge strip material (edge ​​strip roll) on the rotating roller 22, then install the second disc 24, tighten the hand screw to clamp the edge strip roll, and then the free end of the edge strip material comes out.

[0038] like Figure 3As shown, the feeding mechanism 3 includes a feeding base 31 mounted on the machine base, a main feeding roller 32 rotatably mounted on the feeding base 31, a secondary feeding roller 33 arranged parallel to the main feeding roller 32, and a feeding motor 34 for driving the main feeding roller 32 to rotate. The main feeding roller 32 drives the secondary feeding roller 33 to rotate. A feeding gap is provided between the main feeding roller 32 and the secondary feeding roller 33. An edge strip detector 35 is provided on the incoming side of the main feeding roller 32. The edge strip detector 35 is used to detect the presence or absence of edge strips.

[0039] In actual use, the edge strip passes through the feeding gap, and the feeding motor 34 drives the main feeding roller 32 to rotate, which in turn drives the secondary feeding roller 33. Under the action of the main feeding roller 32 and the secondary feeding roller 33, the feeding of the edge strip is realized. The edge strip detector 35 can detect the presence or absence of the edge strip, and stop the feeding motor 34 when there is no edge strip.

[0040] like Figure 5 As shown, the pre-slitting mechanism 4 includes a blade holder 41, a cutter 42, and left and right slitting slide rails 43. The left and right slitting slide rails 43 are mounted on the machine base. The blade holder 41 is slidably connected to the left and right slitting slide rails 43, allowing the user to adjust the position of the blade holder 41 according to the width of the edge strip. The blade holder 41 has an installation gap 411, and the cutter 42 is mounted in the installation gap 411 and fixed to the blade holder 41 by a hand-tightening screw, thus fixing the cutter 42. The cutter 42 can be a utility knife or other tools.

[0041] like Figure 3 As shown, preferably, the glue application mechanism 5 includes a glue application fixed base 51, a glue application lifting cylinder 52, a glue application lifting base 53, a glue application lifting guide rail 54, a glue application transverse moving base 55, a glue application transverse moving guide rail 56, and a glue application gun 57. The glue application fixed base 51 is fixed on the machine base. The glue application lifting cylinder 52 and the glue application lifting guide rail 54 are disposed on the glue application fixed base 51. The glue application lifting cylinder 52 is used to drive the glue application lifting base 53 to move up and down on the glue application lifting guide rail 54. The glue application transverse moving guide rail 56 is disposed on the glue application lifting base 53. The glue application transverse moving base 55 is slidably disposed on the glue application transverse moving guide rail 56. The glue application gun 57 is fixed on the glue application transverse moving base 55.

[0042] The adhesive application lifting guide rail 54 ensures lifting stability. The adhesive application lifting cylinder 52 drives the adhesive application lifting seat 53 to rise and fall, thereby causing the adhesive application transverse seat 55 to drive the adhesive application gun 57 to rise and fall for adhesive application. Because of the adhesive application transverse guide rail 56, the left and right positions of the adhesive application transverse seat 55 can be manually adjusted to accommodate edge strips of different widths.

[0043] like Figure 4As shown, preferably, the cutting mechanism 7 includes a cutting cylinder 71, a cutting blade 72, an oiling cylinder 73, and an oiling cotton 74. The cutting cylinder 71 and the oiling cylinder 73 are mounted on the machine base. The cutting blade 72 is located at the output end of the cutting cylinder 71. The cutting cylinder 71 drives the cutting blade 72 to cut the edge strip. The oiling cotton 74 is located at the output end of the oiling cylinder 73. Under the drive of the oiling cylinder 73, the oiling cotton 74 applies oil to the cutting blade 72 to ensure the cutting effect and prevent the cutting blade 72 from overheating and being damaged.

[0044] like Figure 6 As shown, preferably, the edge strip fixture 6 includes a flipping plate 61 driven by the flipping drive mechanism 8, a fixed plate 62 mounted on the flipping plate 61, a movable plate 63 movably disposed relative to the fixed plate 62, and a positioning cylinder 64 for driving the movable plate 63 away from or closer to the fixed plate 62. A placement groove 65 for placing the edge strip is formed between the fixed plate 62 and the movable plate 63.

[0045] In actual use, the edge strip coated with glue moves onto the flip plate 61 and is placed in the placement groove 65. The positioning cylinder 64 drives the movable plate 63 to move closer to the fixed plate 62. The movable plate 63 pushes the edge strip coated with glue to move, so that both sides of the edge strip contact the movable plate 63 and the fixed plate 62 respectively. The movable plate 63 and the fixed plate 62 clamp and position the edge strip, which improves the stability of the edge strip and ensures the positional accuracy of the edge strip, thereby improving the edge bonding quality of the filter element.

[0046] Preferably, the flipping drive mechanism 8 includes a movable seat 81 slidably connected to the machine base, a rotating shaft 82 rotatably disposed on the movable seat 81, a swing member 83 mounted on one end of the rotating shaft 82, and a flipping drive cylinder 84 for driving the swing member 83 to swing. The flipping plate 61 is mounted on the rotating shaft 82, and the flipping drive cylinder 84 is mounted on the movable seat 81.

[0047] In actual use, the flipping drive cylinder 84 drives the swing component 83 to swing, the swing component 83 drives the rotating shaft 82 to rotate, and the rotating shaft 82 drives the flipping plate 61 to flip, so that the flipping plate 61 flips from a horizontal state to a vertical state, which makes it easier to attach the edge strip to both sides of the filter element and improves the efficiency of edge strip attachment.

[0048] Preferably, the transverse strip application mechanism 9 includes a lead screw motor 91 and a transverse guide rail 92 mounted on the machine base. The movable seat 81 is slidably mounted on the transverse guide rail 92 and connected to the output end of the lead screw motor 91. The lead screw motor 91 drives the movable seat 81 to move transversely, thereby driving the flipping drive mechanism 8 on the movable seat 81 to move transversely, which in turn drives the edge strip fixture 6 to move transversely and apply the edge strip to the side of the filter element.

[0049] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
