Description

Technical Field

[0001] This invention relates to the field of filter element manufacturing technology, specifically to a filter element sealing device and sealing method. Background Technology

[0002] Filter elements are an important component of filters, which are purification devices needed for the purification of raw resources and their reuse. Filter elements are characterized by low pressure drop, strong dirt-holding capacity, and long service life; they are suitable for applications in vacuum coating, machinery, optical discs, metallurgy, petroleum, and refrigeration equipment. During the production of filter elements, sealing is required. A search revealed that a typical existing filter element sealing method is disclosed in CN101912929A, "A Filter Sealing Device and Its Usage Method." This invention includes a motor, a main shaft, a workpiece pressing block, a workpiece tray, a cam, and a pedal. This invention is suitable for the edge sealing of cylindrical parts. The filter element is installed in the filter housing and placed on the workpiece tray. The pedal is pressed down to tighten the workpiece pressing block against the filter element. The motor is started, causing the filter to rotate. The right lever is pulled to roll the filter edge, and then the left lever is pulled to straighten the filter edge. After processing, the pedal is released, and the processed filter can be removed. The filter sealing device shown in this invention can simultaneously perform edge rolling and edge straightening on the workpiece, resulting in high processing efficiency. The positions of the edge rolling wheel and the edge straightening wheel are adjustable, making it suitable for cylindrical workpieces of various diameters. Its main feature is that it does not require operators to have a high level of technical skills.

[0003] In summary, the existing filter cartridge sealing methods have a low degree of automation, requiring manual adjustment of the filter cartridge position, which is inconvenient to use and has low processing efficiency. To address these issues, existing equipment needs to be improved. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filter cartridge sealing device, comprising a frame and an adjusting and limiting mechanism.

[0006] The bottom of the frame is connected to a support frame, and a feeding mechanism is connected to the support frame. The frame is connected to one side of the shelf via a rotating shaft, and driven rollers are symmetrically arranged on the inner side of the shelf. The driven rollers are connected to each other by a conveyor belt, and mounting covers are provided on both the left and right sides of the driven rollers. The mounting covers are installed on the top of the frame. An electric slide rail is installed on one side wall of the mounting cover, and an electric slider is connected to the electric slide rail. The electric slider is fixedly connected to one side wall of the heat sealing knife via a heat insulation frame, and an energy concentrator assembly is connected to the other side wall of the heat sealing knife. The heat sealing knife is located inside the heat sealing groove, and the heat sealing groove is opened on the side wall of the mounting cover. The mounting cover is connected to the inspection plate by bolts.

[0007] The adjusting and limiting mechanism is connected to the fixed frame, and the fixed frame is fixedly connected to the cover on the machine frame. The cover is symmetrically arranged on the machine frame. The adjusting and limiting mechanism includes a second motor, a driving screw, a limiting block, a driven screw, a driven slide, a mounting base, an electric roller, and a driving slide. The second motor is installed on the inner wall of the fixed frame, and the output end of the second motor is connected to the driving screw. Driven screws are symmetrically arranged on both the left and right sides of the driving screw. A driving slide and a driven slide are respectively arranged on the driving screw and the driven screw. The driving slide and the driven slide are fixedly connected to the limiting block and the mounting base, respectively. An electric roller is installed on the mounting base.

[0008] Preferably, the feeding mechanism includes a first motor, a first belt drive structure, a first rotating rod, a second rotating rod, a feeding plate, a cam, and a rotating drum. The output end of the first motor is fixedly connected to the rotating drum. The rotating drum is connected to the first rotating rod and the second rotating rod respectively through the first belt drive structure, and a cam is connected to the rotating drum.

[0009] Preferably, the first motor is mounted on the side wall of the support frame, and the first motor, the rotating drum, the first rotating rod and the second rotating rod constitute a rotating structure.

[0010] Preferably, there are two sets of the first rotating rods, and the first rotating rods are connected by a feeding plate.

[0011] Preferably, the cams are symmetrically arranged on the rotating drum, and the cam protrusions are in contact with the bottom of the storage plate.

[0012] Preferably, the driven rollers are provided with support rollers at equal intervals, and the outer wall of the support rollers is in contact with the inner wall of the conveyor belt.

[0013] Preferably, electric sliders are symmetrically arranged on the electric slide rail, and the two sets of electric sliders move in opposite directions.

[0014] Preferably, the driving screw is connected to the driven screw via a second belt drive structure, and the threads on the driven screw and the threads on the driving screw move in opposite directions. At the same time, the driven screws are connected to each other via the second belt drive structure.

[0015] Preferably, the electric rollers are evenly distributed on the inner wall of the mounting base, and the mounting base is symmetrically arranged on both sides of the limiting block. At the same time, both the limiting block and the mounting base are arranged above the placement plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the filter element sealing method,

[0017] (1) This invention effectively solves the problem of low automation in existing filter element sealing methods by adjusting the limiting mechanism. Specifically, it requires manual adjustment of the filter element's position, making it inconvenient to use and resulting in low processing efficiency. The second motor in the limiting mechanism drives the active lead screw to rotate. With the cooperation of the second belt drive structure, the active lead screw drives the driven lead screw to rotate together. This causes the active slide to move the limiting block outward along the active lead screw, away from the filter element. The driven slide then moves the mounting seat inward along the driven lead screw until the electric roller contacts the side wall of the filter element away from the conveyor belt. The filter element can be moved by an electric roller, which can automatically adjust the sealing position of its port. After the position adjustment is completed, the operator can control the second motor to rotate in the opposite direction, so that the electric roller moves away from the filter element and the limit block fixes the filter element, thereby preventing the filter element from moving during sealing. Compared with the existing filter element sealing method, this application can automatically adjust the sealing position of the filter element, and can automatically position and fix the filter element when performing the opening operation after adjustment, which makes it easier to ensure the quality and efficiency of the filter element, and is more convenient to operate.

[0018] (2) The present invention can effectively solve the problem that the existing filter element sealing method requires manual unloading after the splitting operation, which makes the labor intensity of the workers high. The first motor in the unloading mechanism drives the rotating drum to rotate. The rotating drum, in cooperation with the first belt transmission structure, will simultaneously drive the first rotating rod and the second rotating rod to rotate. The unloading plate rotates under the drive of the first rotating rod and is inclined in the front side and the rear side is high. During the rotation of the second rotating rod, it will drive the cam to rotate. When its top is away from the placement plate, the front side of the placement plate will lose support and flip under the connection of the rotating shaft, so that the filter element on its top falls onto the inclined unloading plate and completes automatic unloading along the inclined upper surface of the unloading plate. Compared with the manual handling unloading method in the existing filter element sealing method, it is more labor-saving, convenient and fast.

[0019] (3) The present invention can effectively solve the problem that the existing filter cartridge sealing method can only perform auxiliary conveying and limiting work on one filter cartridge at a time during the sealing operation by using the driven roller and the conveyor belt. That is, only one filter cartridge can be sealed at a time, which results in low efficiency. The conveyor belt on the driven roller will move with the filter cartridge during the process of the electric roller driving the filter cartridge. Since the moving direction of the conveyor belt on both sides is opposite, it can meet the auxiliary conveying and limiting work of two different electric rollers. That is, through the cooperation of the conveyor belt and the driven roller, the present invention can simultaneously perform auxiliary conveying and auxiliary position adjustment on two sets of filter cartridges. That is, the conveying, opening position adjustment and sealing operation of two sets of filter cartridges can be completed in the same time, thereby improving the sealing efficiency.

[0028] like Figures 1-6 As shown, a filter cartridge sealing device includes a frame 1 with a support frame 2 connected to the bottom, and a feeding mechanism 3 connected to the support frame 2.

[0029] The feeding mechanism 3 includes a first motor 301, a first belt drive structure 302, a first rotating rod 303, a second rotating rod 304, a feeding plate 305, a cam 306, and a rotating drum 307.

The rotating drum 307 is connected to the first rotating rod 303 and the second rotating rod 304 respectively through the first belt drive structure 302. The cam 306 is connected to the rotating drum 307.

[0030] The first motor 301 is mounted on the side wall of the support frame 2, and the first motor 301, the rotating drum 307, the first rotating rod 303 and the second rotating rod 304 constitute a rotating structure.

[0031] Two sets of first rotating rods 303 are provided, and the first rotating rods 303 are connected to each other by a feeding plate 305.

[0032] Cams 306 are symmetrically arranged on the rotating cylinder 307, and the protrusions of cams 306 are in contact with the bottom of the storage plate 4.

[0033] The frame 1 is connected to one side of the shelf 4 via a rotating shaft 5. Driven rollers 6 are symmetrically arranged on the inner side of the shelf 4. The driven rollers 6 are connected to each other via a conveyor belt 7. Mounting covers 10 are provided on both the left and right sides of the driven rollers 6. The mounting covers 10 are installed on the top of the frame 1. An electric slide rail 15 is installed on one side wall of the mounting cover 10. An electric slider 14 is connected to the electric slide rail 15. The electric slider 14 is fixedly connected to one side wall of the heat sealing knife 11 via a heat insulation frame 13. An energy concentrator assembly 12 is connected to the other side wall of the heat sealing knife 11. The heat sealing knife 11 is located inside the heat sealing groove 16. The heat sealing groove 16 is opened on the side wall of the mounting cover 10. The mounting cover 10 is connected to the inspection plate 17 via bolts.

[0034] Specifically, the use of the heat sealing knife 11 for sealing is an existing technology, and its specific principles and working process will not be elaborated here.

[0035] Support rollers 8 are evenly spaced between driven rollers 6, and the outer wall of the support rollers 8 is in contact with the inner wall of the conveyor belt 7.

[0036] Specifically, the support roller 8 plays an auxiliary supporting and limiting role when the limiting block 1903 and the electric roller 1907 fix and move the filter element.

[0037] Electric sliders 14 are symmetrically arranged on the electric slide rail 15, and the two sets of electric sliders 14 move in opposite directions.

[0038] The adjusting limit mechanism 19 is connected to the fixed frame 18, and the fixed frame 18 is fixedly connected to the cover 9 on the machine frame 1. The cover 9 is symmetrically arranged on the machine frame 1. The adjusting limit mechanism 19 includes a second motor 1901, a driving screw 1902, a limit block 1903, a driven screw 1904, a driven slide 1905, a mounting base 1906, an electric roller 1907, and a driving slide 1908. The second motor 1901 is mounted on the inner wall of the fixed frame 18. The output end of the second motor 1901 is connected to the active lead screw 1902. The active lead screw 1902 is symmetrically provided with driven lead screws 1904 on both the left and right sides. The active lead screw 1902 and the driven lead screw 1904 are respectively provided with an active slide 1908 and a driven slide 1905. The active slide 1908 and the driven slide 1905 are respectively fixedly connected to the limit block 1903 and the mounting base 1906. An electric roller 1907 is installed on the mounting base 1906.

[0039] The driving screw 1902 is connected to the driven screw 1904 through a second belt drive structure, and the thread on the driven screw 1904 moves in the opposite direction to the thread on the driving screw 1902. At the same time, the driven screws 1904 are connected to each other through the second belt drive structure.

[0040] Specifically, the opposite threads facilitate the movement of the active slide 1908 and the driven slide 1905 in opposite directions during synchronous rotation, thereby facilitating the alternating contact between the limit block 1903 and the electric roller 1907 and the filter element.

[0041] Electric rollers 1907 are evenly distributed on the inner wall of mounting base 1906, and mounting base 1906 is symmetrically arranged on both sides of limiting block 1903. At the same time, both limiting block 1903 and mounting base 1906 are arranged above the shelf 4.

[0042] A sealing method using a filter cartridge sealing device includes the following steps:

[0043] First, the second motor 1901 drives the active lead screw 1902 to rotate. The active lead screw 1902 drives the driven lead screw 1904 to rotate through the second belt transmission structure, thereby causing the active slide 1908 to move away from the filter element. The driven slide 1905 drives the mounting base 1906 to move inward until the electric roller 1907 contacts one side wall of the filter element. At this time, the other side wall of the filter element contacts the outer wall of the conveyor belt 7.

[0044] Next, the electric roller 1907 will rotate to push the filter element to move, that is, automatically adjust its position on the shelf 4. At the same time, the filter element will push the conveyor belt 7 to move in the same direction during the movement, so as to limit its movement and prevent its position from shifting during the movement.

[0045] When it is necessary to seal the port of the filter element, the operator can control the second motor 1901 to drive the active screw 1902 to rotate in the opposite direction, so that the electric roller 1907 can move away from the side wall of the filter element and stop the adjustment operation. At the same time, the limit block 1903 will move until it contacts the side wall of the filter element, so that the filter element can be squeezed and limited.

[0046] Next, the electric slider 14 will drive the heat sealing knife 11 to move up and down along the electric slide rail 15 to heat seal one end of the filter element. At the same time, with the cooperation of the electric roller 1907, it will move to the other side and use another set of heat sealing knives 11 to seal the other end.

[0047] After heat sealing is completed, the first motor 301 drives the rotating drum 307 to rotate. During the rotation of the rotating drum 307, the first rotating rod 303 and the second rotating rod 304 will rotate through the first belt drive structure 302. During the rotation of the second rotating rod 304, the cam 306 will rotate. After the cam 306 moves away from the placement plate 4, the front side of the placement plate 4 will rotate due to loss of support, causing the filter element on top to fall onto the feeding plate 305. The feeding plate 305 is tilted at this time under the drive of the first rotating rod 303, so that the filter element is automatically fed along the tilted upper surface of the feeding plate 305.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
