Abstract
Description
Technical Field
[0001] This invention relates to filter manufacturing equipment, and more specifically to a filter paper pressing, folding, and edge-sealing device used in the production of filter components. Background Technology
[0002] Currently, air filters generally consist of a housing and filter element assembly. The filter element assembly comprises upper and lower end caps, filter paper, and a central tube. The manufacturing process of the filter paper typically involves unwinding, pressing, edge trimming, folding and rewinding, rewinding, edge attaching, and slitting, a semi-automatic production method. Each of the folding and rewinding processes requires separate equipment, and manual operation is still necessary. The folding and rewinding processes involve using a single pressure plate to create creases at intervals on the flat filter paper through vertical pressing, followed by folding according to the creases. No shaping (drying) or equidistant folding is performed. The folded filter paper is then manually edged and manually trimmed for waste. This semi-automatic process results in low automation, poor efficiency, and difficulty in guaranteeing processing quality. The produced filter paper is particularly unsuitable for high-performance air conditioning filters used in vehicle air conditioning systems. Summary of the Invention
[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a fully automatic linear arrangement filter paper pressing, folding, and edge-sealing device for filter paper production, which can perform filter paper pressing, folding, shaping, folding, and edge sealing in a one-time assembly line.
[0004] The objective of this invention is achieved through the following technical solution: a fully automatic filter paper pressing, folding, and edge-sealing device with a straight-line arrangement, comprising an unwinding mechanism and a cutting and feeding mechanism. A pressing and folding feeding mechanism, a drying and shaping mechanism, and a folding and edge-sealing mechanism are sequentially installed on the side of the cutting and feeding mechanism. The unwinding mechanism, the cutting and feeding mechanism, the pressing and folding feeding mechanism, the drying and shaping mechanism, and the folding and edge-sealing mechanism are arranged in a straight line and in a "I" shape.
[0005] The folding and receiving mechanism includes an adjacent folding frame, a transition feeding frame, and a receiving frame. The folding frame is equipped with an upper and lower folding roller, both of which are vertically rolling. The lower folding roller is connected to a folding power source via a folding transmission assembly. Both the upper and lower folding rollers have several folding crossbars. The transition feeding frame is equipped with an upper and lower feeding roller, both of which are vertically rolling. The lower feeding roller is connected to a transition feeding power source via a feeding transmission assembly. The transition paper feeder frame is equipped with an upper pressure guide plate and a lower pressure guide plate at the exit of the upper and lower paper feed rollers, respectively. There is a gap between the upper pressure guide plate and the lower pressure guide plate to allow the transition paper to pass through. Several sets of upper and lower paper feed rollers are respectively mounted on the paper take-up frame via upper and lower paper take-up roller mounting shafts. Upper and lower paper take-up guide strips are respectively mounted on the sides of the upper and lower paper take-up rollers. The upper and lower paper take-up roller mounting shafts are connected to the pressure and folding power source through the pressure and take-up transition transmission assembly.
[0006] Both the upper and lower feed rollers have several equidistant notches. The upper and lower pressure guide plates have corresponding upper and lower curved pieces with equidistant notches extending onto the upper and lower feed rollers, respectively, to clamp the filter paper fed between the upper and lower feed rollers, preventing it from being wound up or down by the upper and lower feed rollers during transport. The paper receiving frame is mounted on a front and rear adjusting rack, which is connected to an adjusting handwheel via a front and rear adjusting gear and a front and rear adjusting shaft.
[0007] The folding and edge-fitting mechanism includes adjacent folding and feeding frames, a folding frame, and an edge-fitting frame. The folding and feeding frame is equipped with an upper and lower rolling folding and feeding roller, which is connected to a folding and feeding power source. The folding frame is also equipped with an upper and lower rolling folding and fixing screw, arranged perpendicularly to the upper and lower rollers. Both the upper and lower folding and fixing screws have equally spaced threads. These screws are connected to the folding and fixing power source via a fixing screw transmission assembly. The edge-fitting frame, along with the upper and lower rolling screws... The two sides of the fixed-distance screw are equipped with a synchronous transmission assembly for the edge-applying strip. The synchronous transmission assembly includes an active synchronous pulley, a driven synchronous pulley, and a synchronous belt. The active synchronous pulley is connected to the power source. An upper pressing plate and a lower reference plate are installed on the edge-applying frame and on the outer side of the synchronous belt. An edge-applying limit block, a guide block, a guide wheel, and a height limit plate are also installed sequentially on the edge-applying frame and on the outer side of the synchronous belt. A glue gun and an edge-applying strip roll are installed sequentially on the periphery of the edge-applying frame and on the side of the guide wheel.
[0008] The paper feeding frame is equipped with a front and rear adjustment guide seat, and an upper and lower adjustment guide plate is installed on the front and rear adjustment guide seat. The guide plate adjusts the front and rear position and the upper and lower position of the paper feeding upper and lower pressure rollers to correspond to the crease height of the filter paper.
[0009] By adopting this invention, the filter paper is unwound by the unwinding mechanism, initially cut and fed by the edge-cutting and feeding mechanism, folded and collected by the pressing and folding mechanism to create transverse, equidistant indentations, transitionally fed, and collected. Then, it is dried and shaped by the drying and shaping mechanism. Finally, the folding and edge-fitting mechanism performs folding and feeding, fixed-distance folding, and edge-fitting on both sides (without needing to cut waste). Thus, the filter paper is produced in a fully automated manner in a straight line and in a one-time flow, completing a series of manufacturing processes such as pressing and folding, transition feeding, collecting, shaping, fixed-distance folding, and edge-fitting. The resulting filter paper is folded to the same height (and can be used independently as a filter element). It is precise in pressing and folding, firmly shaped, and highly efficient, significantly improving the quality and service life of the filter paper. It is especially suitable for vehicle air conditioning filters. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0021] See attached document Figures 1 to 9 As can be seen, the present invention relates to a fully automatic linear arrangement filter paper pressing, folding, and edge-sealing device for filter paper production in filter equipment, comprising an unwinding mechanism 1 and a cutting and feeding mechanism 2. A pressing and folding feeding mechanism 3, a drying and shaping mechanism 4, and a folding and edge-sealing mechanism 6 are sequentially installed on the side of the cutting and feeding mechanism 2. The unwinding mechanism 1, cutting and feeding mechanism 2, pressing and folding feeding mechanism 3, drying and shaping mechanism 4 (drying and shaping is performed by a built-in drying lamp), and folding and edge-sealing mechanism 6 are arranged in a straight line and a "I"-shaped distribution. A long strip edge-sealing filter paper conveying mechanism 7 and a long strip edge-sealing filter paper slitting mechanism 8 are also sequentially installed on the side of the folding and edge-sealing mechanism 6. The unwinding mechanism 1, cutting and feeding mechanism 2, pressing and folding feeding mechanism 3, drying and shaping mechanism 4, folding and edge-sealing mechanism 6, long strip edge-sealing filter paper conveying mechanism 7, and long strip edge-sealing filter paper slitting mechanism 8 are all electrically connected to a microcomputer control mechanism 9 for unified control.
[0022] like Figures 2 to 5As shown, the folding and receiving mechanism 3 includes an adjacent folding frame 31, a transition feeding frame 32, and a receiving frame 33. The folding frame 31 is equipped with an upper folding roller 34 (located in the upper position, mounted on the folding frame 31 via a folding slide 39 to adjust the distance between it and the lower folding roller) and a lower folding roller 35 (located in the lower position). The lower folding roller 35 is connected to a folding power source 37 (a folding motor) via a folding transmission assembly 36. The upper and lower folding rollers 34 and 35 are connected, each having several folding strips 38 (vertically aligned, spaced a certain distance apart, to fold the filter paper into transverse indentations); the transition feeder frame 32 is equipped with an upper feed roller 41 (upper position) and a lower feed roller 42 (lower position), the lower feed roller 42 being connected to the transition feed power source 44 (transition feed motor) via a feed transmission assembly 43. The transition paper feed frame 32 is equipped with an upper pressure guide plate 45 and a lower pressure guide plate 46 at the outlets of the upper and lower paper feed rollers, respectively. A gap exists between the upper pressure guide plate 45 and the lower pressure guide plate 46 to allow the transition paper feed to pass through. The take-up frame 33 is equipped with several sets of vertically arranged upper take-up rollers 53 (in the upper position) and lower take-up rollers 54 (in the lower position) respectively, mounted via an upper take-up roller mounting shaft 51 and a lower take-up roller mounting shaft 52. 3 and 54 are respectively equipped with upper take-up guide strip 55 and lower take-up guide strip 56 (there is a gap between the upper take-up guide strip 55 and the lower take-up guide strip 56 to allow filter paper to pass through). The upper and lower take-up roller mounting shafts 51 and 52 are connected to the pressing and folding power source 37 through the pressing and folding transition transmission assembly 58 (including take-up sprocket 57 mounted on the outer end of the upper and lower take-up roller mounting shafts, pressing and folding sprocket 59 mounted on the outer end of the pressing and folding upper roller, and interconnected chains 89, etc.). The folding frame 31, upper folding roller 34, lower folding roller 35, folding transmission assembly 36, and folding power source 37 constitute the filter paper folding assembly 30. The transition paper feeding frame 32, upper paper feeding roller 41, lower paper feeding roller 42, upper pressure guide plate 45, lower pressure guide plate 46, paper feeding transmission assembly 43, and transition paper feeding power source 44 constitute the transition paper feeding assembly 40. The paper receiving frame 33, upper paper receiving roller mounting shaft 51, lower paper receiving roller mounting shaft 52, upper paper receiving roller 53, lower paper receiving roller 54, upper paper receiving guide bar 55, and lower paper receiving guide bar 56 constitute the filter paper receiving assembly 50. The filter paper folding assembly 30, transition paper feeding assembly 40, and filter paper receiving assembly 50 constitute the folding and receiving mechanism 3.
[0023] like Figure 4 , Figure 10As shown, the upper and lower paper feeding rollers 41 and 42 each have several equidistant notches 47. The upper pressure guide plate 45 and the lower pressure guide plate 46 correspond to the upper curved piece 48 and the lower curved piece 49, which have equidistant notches extending onto the upper and lower paper feeding rollers, respectively, so as to clamp the filter paper transitioning between the upper and lower paper feeding rollers and prevent it from being wound up or down by the upper and lower paper feeding rollers during transport. Figure 5 As shown, the paper receiving frame 33 is mounted on the front and rear adjusting rack 91. The front and rear adjusting rack 91 is connected to the adjusting handwheel 94 through the front and rear adjusting gear 92 and the front and rear adjusting shaft 93 to adjust the front and rear position of the paper receiving frame (i.e., adjust the distance between the paper receiving frame and the transition paper feeding frame) and thus change the crease height of the filter paper.
[0024] As shown in the attached diagram, filter paper 5 (roll type) is unwound by the unwinding mechanism 1, initially trimmed by the edge-cutting and feeding mechanism 2, and conveyed to the pressing and folding receiving mechanism 3. Driven by the pressing and folding power source 37 and the pressing and folding transmission assembly 36, the filter paper passes between the pressing upper roller 34 and the pressing lower roller 35, and is pressed by the pressing crossbar 38 to create transverse, evenly spaced indentations. Then, driven by the transition feeding power source 44 and the feeding transmission assembly 43, the filter paper enters between the upper feeding roller 41 and the lower feeding roller 42, and is pressed by the upper pressure guide plate 45 and the... The filter paper is conveyed by the pressure guide plate 46 and the pressure guide plate between the upper and lower bending plates. Then, the filter paper continues to enter between the upper paper take-up roller 53 and the lower paper take-up roller 54 through the linkage of the pressure power source 37 and the paper take-up transition transmission assembly 58. The paper is taken up manually (an upper paper take-up guide bar in the middle position can be removed to facilitate manual paper take-up with fingers). The filter paper with equal distance between the upper paper take-up guide bar 55 and the lower paper take-up guide bar 56 is output and then enters the drying and shaping mechanism 4 for drying and shaping.
[0025] like Figures 6 to 9As shown, the folding and edge-fitting mechanism 6 includes adjacent folding and feeding frames 60, folding frames 61, and edge-fitting frames 62. The folding and feeding frame 60 is equipped with an upper folding and feeding roller 63 and a lower folding and feeding roller 64, which are connected to a folding and feeding power source 65 (a folding and feeding motor) (forming the folding and feeding assembly 90). The folding frame 61 is equipped with an upper folding and lower folding fixing screw 66 and a lower folding fixing screw 64, which are respectively arranged perpendicularly to the upper folding and feeding roller 63 and the lower folding and feeding roller 64. 7 (can be two sets, front and rear), both the upper folding and fixing screw 66 and the lower folding and fixing screw 67 have equally spaced threads (helical type, matching the folding spacing requirements of the filter paper). The upper and lower folding and fixing screws 66 and 67 are connected to the folding and fixing power source 69 (a folding and fixing motor) through the fixing screw transmission assembly 68 (a combination of mutually perpendicular meshing transmission bevel gears, transmission splines, etc.) (to achieve the fixing folding and fixing of the filter paper, forming the fixing folding and fixing assembly 80); on the edge-sealing frame 62, and on the upper folding and fixing screw 66 and the lower folding and fixing screw The edge-fitting frame 67 is equipped with a synchronous transmission assembly 70 for the edge-fitting strip on both sides. The synchronous transmission assembly 70 includes an edge-fitting strip driving synchronous pulley 71, an edge-fitting strip driven synchronous pulley 72, and an edge-fitting strip synchronous belt 73. The edge-fitting strip driving synchronous pulley 71 is connected to the edge-fitting strip power source 74 (which is an edge-fitting strip motor). On the edge-fitting frame 62, and on the outer side of the edge-fitting strip synchronous belt 73 (via the edge-fitting strip pressing mounting plate 84, which is located inside the edge-fitting strip synchronous belt), there is an upper edge-fitting strip pressing plate 75 (located above the conveyed edge-fitting strip) and a lower edge-fitting strip reference plate. 85 (At the lower position of the conveyed edge-applying strip, the edge-applying strip is positioned and pressed to prevent it from moving up and down). On the edge-applying frame 62 and on the outer side of the edge-applying strip synchronous belt 73, an edge-applying strip limiting block 76, an edge-applying strip guide block 77, an edge-applying strip guide wheel 78, and an edge-applying strip height limiting plate 79 (arranged from the inside out and all mounted on the edge-applying strip conveying mounting plate 83) are also installed in sequence. On the periphery of the edge-applying frame 62 and on the side of the edge-applying strip guide wheel 78, a glue gun 81 and an edge-applying strip roll 82 (for applying glue to the unwound edge-applying strip) are installed in sequence. The paper feeding and folding assembly 90, the fixed-distance folding assembly 80, and the edge-applying strip synchronous transmission assembly 70 constitute the folding and edge-applying mechanism 6.
[0026] like Figure 7 As shown, a front-to-back adjusting guide seat 86 (arranged in the front-to-back direction and having an adjusting groove 88) is installed on the paper feeding frame 60. An upper-to-lower adjusting guide plate 87 (arranged in the upper and lower longitudinal direction) is installed on the front-to-back adjusting guide seat 86. The upper and lower pressure rollers of the paper feeding frame are adjusted in the front-to-back position (i.e., the distance between them and the upper and lower paper feeding distance screws) and in the upper and lower position, which corresponds to the change in the crease height of the filter paper.
[0027] As shown in the attached figure, the dried and shaped press-folded equal-distance filter paper enters the upper and lower fold-folding paper feeding rollers 63 and 64 of the fold-folding and edge-fitting mechanism 6, and is conveyed by the fold-folding and paper feeding power source 65 into the space between the upper fold-folding and fixed-distance screw 66 and the lower fold-folding and fixed-distance screw 67. Driven by the fold-folding and fixed-distance power source 69 and the fixed-distance screw transmission assembly 68, it undergoes fixed-distance and equal-height folding to produce folded long strip filter paper with fixed distance and equal height.
[0028] Simultaneously, the edge-attaching strip roll 82 is unwound and glued by the glue gun 81. Guided by the edge-attaching strip limiting block 76, edge-attaching strip guide block 77, edge-attaching strip guide wheel 78, and edge-attaching strip height limiting plate 79, it adheres to the outer surface of the edge-attaching strip synchronous belt 73. Driven by the edge-attaching strip power source 74, the edge-attaching strip active synchronous wheel 71, and the edge-attaching strip driven synchronous wheel 72, it reaches the side of the folded long strip filter paper at a fixed distance and equal height, and is positioned between the edge-attaching strip upper pressing plate 75 and the edge-attaching strip lower reference plate 85, thereby automatically attaching the edges of the filter paper. Finally, it is conveyed by the long strip edge-attached filter paper conveying mechanism 7 and automatically cut by the long strip edge-attached filter paper slitting mechanism 8 to obtain the finished folded filter paper product of equal height (this flat filter paper product can be used directly as a filter element independently without the need for assembling upper and lower end caps and a central tube).
