Description

Technical Field

[0001] This invention relates to the field of battery plastic casing recycling devices, specifically to a recycling device and method for recycling plastic casings of used automobile batteries. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the amount of scrapped power batteries has been increasing year by year. At present, the recycling and processing of such plastic shells usually includes processes such as crushing, sorting, washing, and granulation. Among them, the screening of crushed particles is a key link that affects the efficiency of subsequent processing and the quality of recycled products.

[0003] Existing recycling devices mostly use fixed screens or vibrating screens to classify and filter crushed plastic particles. However, in actual operation, especially when processing irregularly shaped and highly resilient battery plastic shells, the flaky or fibrous materials produced by crushing are very easy to clog the screen mesh, causing the filtration efficiency to drop rapidly. This not only affects the smoothness of continuous operation, forcing the production line to frequently stop for manual cleaning or screen replacement, increasing maintenance costs and manual intervention intensity, but may also cause some qualified fine particles to be mixed in with the coarse material due to incomplete screening, reducing the purity and value of the recycled material.

[0004] The following problems exist in the existing technology that have not been well resolved: Existing improvement solutions attempt to use movable or switchable filters, or to add cleaning components such as rotating brushes near the screen, but these solutions often have new limitations: For example, 1. The switching or cleaning action of the filter usually requires an independent drive mechanism, which makes the equipment structure complex and increases the cost; 2. The continuous scraping between the cleaning component and the moving filter can easily accelerate the wear of both and shorten their service life, or the cleaning action is carried out simultaneously with the filtration process, which interferes with the normal filtration and classification effect and results in incomplete cleaning. Summary of the Invention

The middle part of the gas collecting sleeve is fixedly connected to a sealing ring that cooperates with the positioning nozzle rod.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] In this invention, the transmission gear set driven by the crushing roller controls the filtration adjustment mechanism and the cleaning mechanism, so that the power of the crushing operation is converted into the intermittent displacement of the filter screen and the timing-shifted action of the cleaning mechanism. The filter screen switches positions when needed, while the cleaning operation is precisely performed when the filter screen is paused. The two do not interfere with each other, and there is no need to configure an additional drive source for the filtration and cleaning functions. This simplifies the overall structure, reduces equipment energy consumption and manufacturing costs, and realizes the automation and uninterrupted operation of the entire "crushing-filtration-cleaning" process. It effectively solves the problem of frequent shutdowns for screen cleaning due to blockage and greatly improves the recycling efficiency.

[0032] In this invention, the cleaning mechanism ensures that the movement of the cleaning plate and the movement of the filter screen are strictly staggered by a specific phase setting between the cam and the single-tooth bevel ring. Specifically, the cam only drives the cleaning plate to extend when the filter screen has completed one displacement and is in a stationary state, so that the cleaning bristles of the cleaning plate can be embedded in the stationary filter screen for cleaning. This avoids the rapid wear caused by continuous friction between the cleaning components and the moving filter screen in the traditional method, which not only ensures the cleaning effect, but also significantly extends the service life of the filter screen and the cleaning plate, and reduces the long-term maintenance and replacement costs of the equipment.

[0033] In this invention, the reciprocating motion of the positioning nozzle rod within the air collection sleeve precisely guides the cleaning plate. Simultaneously, the internal piston ring and one-way valve structure directly convert the mechanical motion into suction and jetting actions. Utilizing the kinetic energy of the cleaning mechanism itself, a high-speed airflow is ejected from the rod end when the cleaning plate resets, effectively blowing away fine dust embedded in the mesh, thus improving the thoroughness of cleaning. Furthermore, the structure is compact, energy-efficient, and highly effective. Attached Figure Description

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figures 1 to 16 This invention provides a technical solution: a recycling device for plastic casings of used automotive batteries, comprising a recycling bin 1, with crushing rollers 2 symmetrically rotatably mounted on the upper part of the inner wall of the recycling bin 1, and a drive motor 3 for driving the crushing rollers 2 to rotate fixedly connected to the outer wall of the recycling bin 1. A transmission gear set 4, which cooperates with the rotating end of the crushing rollers 2, is rotatably mounted in the middle of the recycling bin 1. It should be noted that the drive motor 3 is installed on the rear side of the recycling bin 1, and the rotating end of the drive motor 3 is fixedly connected to the end of the left crushing roller 2, so that the left crushing roller 2 can drive the transmission gear set 4 during rotation.

[0053] It also includes a filter adjustment mechanism 5, which is installed between the recycling bin 1 and the transmission gear set 4, for adjusting the position of the filter screen 510.

[0054] The cleaning mechanism 6, which is installed on both sides of the recycling bin 1 and cooperates with the filter adjustment mechanism 5, is used to clean the filter screen 510.

[0055] In this embodiment, as Figures 1 to 16As shown, the filter adjustment mechanism 5 includes: magnetic block rods 501 symmetrically fixedly connected to the front side of the recycling bin 1, an adjustment bracket 502 slidably arranged between the two magnetic block rods 501, a transmission rod 503 rotatably connected to the middle of the adjustment bracket 502, and a cam 504 that cooperates with the cleaning mechanism 6 is fixedly sleeved on the surface of the transmission rod 503.

[0056] A single-tooth bevel ring 505 is symmetrically arranged inside the adjusting bracket 502, and the single-tooth bevel ring 505 is fixedly sleeved on the surface of the transmission rod 503. The lower end of the transmission gear set 4 extends into the adjusting bracket 502 and engages with the two single-tooth bevel rings 505 for transmission. It should be noted that the transmission rod 503 is a telescopic transmission rod, and a connecting bearing is fixedly connected between the surface of the adjusting bracket 502 and the surface of the transmission rod 503. When the adjusting bracket 502 slides between the two magnetic blocks 501, the adjusting bracket 502 can synchronously extend and retract the transmission rod 503. When the transmission rod 503 retracts, the single-tooth bevel ring 505 at the front end of the surface of the transmission rod 503 meshes with the lower end of the transmission gear set 4. When the transmission rod 503 extends, the single-tooth bevel ring 505 at the rear end of the surface of the transmission rod 503 meshes with the lower end of the transmission gear set 4.

[0057] A wedge-shaped toothed plate 506 is horizontally slidably disposed inside the adjusting bracket 502 and between the surface of the recycling box 1. The top of the wedge-shaped toothed plate 506 meshes with a single tooth of the adjacent single-tooth bevel ring 505. A transmission pressure rod 507 that cooperates with the side wall of the wedge-shaped toothed plate 506 is symmetrically fixedly connected to the inner wall of the adjusting bracket 502. It should be noted that when the transmission gear set 4 meshes with the corresponding single-tooth bevel ring 505, the single-tooth bevel ring 505 can intermittently mesh with the wedge-shaped toothed plate 506 through the single tooth of the outer ring, driving the wedge-shaped toothed plate 506 to move towards the transmission pressure rod 507 on the inner wall of the adjusting bracket 502. Since the wedge-shaped toothed plate 506 can only slide horizontally, the inclined surface at the end of the wedge-shaped toothed plate 506 contacts the transmission pressure rod 507. The pressed transmission pressure rod 507 runs along the inclined surface trajectory and carries the adjusting bracket 502 to slide longitudinally between the two magnetic block rods 501, switching the position of the adjusting bracket 502.

[0058] A cleaning chamber 508 is symmetrically arranged inside the recycling bin 1. A winding roller 509 is rotatably mounted between the two sides of the inner wall of the cleaning chamber 508. A filter screen 510 is wound between the two winding rollers 509, with the middle of the filter screen 510 movably inserted between the two cleaning chambers 508. It should be noted that when the two winding rollers 509 synchronously rotate forward and backward, winding and unwinding the filter screen 510, the position of the filter surface of the filter screen 510 at the bottom of the crushing roller 2 can be adjusted to ensure that the filter screen 510 effectively filters the crushed plastic particles. Furthermore, a guide roller is rotatably mounted on the upper part of the inner wall of the cleaning chamber 508, cooperating with the filter screen 510 to guide the conveying of the filter screen 510.

[0059] A synchronous belt 511 is movably connected between the front ends of the two take-up rollers 509. A synchronous gear rod 512, which engages with the synchronous belt 511, is rotatably mounted on the front side of the recovery box 1. A synchronous toothed roller 513, which meshes with the bottom of the wedge-shaped toothed plate 506, is rotatably mounted on the bottom of the adjusting bracket 502. The bottom of the synchronous toothed roller 513 meshes with the surface of the synchronous gear rod 512. It should be noted that during the intermittent translation of the wedge-shaped toothed plate 506 within the adjusting bracket 502, the bottom of the wedge-shaped toothed plate 506 meshes with the synchronous toothed roller 513. The synchronous toothed roller 513 drives the synchronous gear rod 512 to engage with the synchronous belt 511, causing the two take-up rollers 509 to rotate synchronously. During this process, the take-up rollers 509 rotate intermittently along with the wedge-shaped toothed plate 506.

[0060] In this embodiment, as Figures 1 to 16 As shown, the transmission gear set 4 includes a limiting bracket 401, a bevel gear 402, an end face gear ring 403, and a spur gear 404. The limiting bracket 401 is fixedly connected to the front side of the recycling box 1. The bevel gear 402 is rotatably disposed in the middle of the limiting bracket 401. The end face gear ring 403 is fixedly connected to the top of the bevel gear 402. The spur gear 404 is rotatably disposed on the surface of the recycling box 1, and the bottom of the spur gear 404 meshes with the top of the end face gear ring 403. It should be noted that a mounting bearing is fixedly connected between the surface of the bevel gear 402 and the inner wall of the limiting bracket 401 to ensure that the bevel gear 402 rotates stably inside the limiting bracket 401. The single-tooth bevel gear ring 505 and the bevel gear 402 are configured as large and small gears. By changing the transmission ratio, the turnover speed of the single-tooth bevel gear ring 505 is effectively reduced, thereby reducing the position switching speed of the filter screen 510.

[0061] The top of the adjusting bracket 502 has a through groove, and the bottom of the bevel gear 402 passes through the through groove and meshes with the side wall of the adjacent single-tooth bevel gear ring 505. It should be noted that when the adjusting bracket 502 slides between the two magnetic block rods 501, the through groove prevents interference between the bevel gear 402 and the adjusting bracket.

[0062] Both crushing rollers 2 have transmission gears 405 fixedly sleeved at their front ends, and the two transmission gears 405 mesh for transmission. Synchronous transmission wheels are fixedly sleeved on the front end of the left crushing roller 2 and the surface of the spur gear rod 404. A transmission belt 406 is movably arranged between the two synchronous transmission wheels. It should be noted that when the left crushing roller 2 rotates, the synchronous transmission wheels and transmission belt 406 work together to drive the spur gear rod 404 to rotate synchronously. This causes the spur gear rod 404 to mesh with the end face toothed ring 403 and drive the bevel gear rod 402 to rotate. The bevel gear rod 402 meshes with the adjacent single-tooth bevel gear ring 505 for transmission. The side wall of the single-tooth bevel gear ring 505 has an annular bevel tooth surface that meshes with the bevel gear rod 402, while the outer ring has a single tooth that meshes with the wedge-shaped tooth plate 506.

[0063] In this embodiment, as Figures 1 to 16 As shown, magnetic ring brackets 514 are fixedly connected to both sides of the adjusting bracket 502. The two magnetic ring brackets 514 are slidably disposed on the surfaces of the two magnetic block rods 501. Two magnetic pieces 515 are disposed on the surface of each magnetic block rod 501, with each magnetic piece 515 corresponding to one side of a magnetic ring bracket 514. It should be noted that when the adjusting bracket 502 slides and displaces on the surfaces of the two magnetic block rods 501, the magnetic rings on the surface of the magnetic ring brackets 514 engage with the corresponding magnetic pieces 515 to limit the movement, ensuring the stability of the adjusting bracket 502 after displacement.

[0064] The adjusting bracket 502 has movable slots on both sides, and guide rods 516 are slidably provided on both sides of the wedge-shaped toothed plate 506. The two guide rods 516 are respectively inserted into the two movable slots, and one end of the guide rod 516 passes through the movable slot and is fixedly connected to the surface of the recycling box 1. It should be noted that: by setting the guide rod 516, the wedge-shaped toothed plate 506 can only move laterally at the front end of the recycling box 1. When the adjusting bracket 502 slides longitudinally between the two magnetic block rods 501, the adjusting bracket 502 drives the two single-tooth bevel rings 505 on the transmission rod 503 to switch their meshing positions with the bevel rod 402. At the same time, the two single-tooth bevel rings 505 move longitudinally and switch their meshing positions with the wedge-shaped toothed plate 506. At this time, only one single-tooth bevel ring 505 is meshed with the bevel rod 402 and the wedge-shaped toothed plate 506, ensuring the stability of the position adjustment of the adjusting bracket 502. In addition, the inner wall of the wedge-shaped toothed plate 506 is fixedly connected with a spring damping plate that cooperates with the guide rod 516, so that the translation of the wedge-shaped toothed plate 506 can only be driven by the single-tooth bevel rings 505, avoiding instability in the translation of the wedge-shaped toothed plate 506.

[0065] In this embodiment, as Figures 1 to 16 As shown, a recycling bin 517 that cooperates with the crushing roller 2 is provided in the middle of the inner wall of the recycling bin 1. Two cleaning bins 508 are respectively provided on both sides of the recycling bin 517. A rectangular groove is provided between the inner walls of the recycling bin 517 and the cleaning bin 508. The middle part of the filter screen 510 is inserted between the two rectangular grooves.

[0066] The rectangular groove has slots at both the top and bottom, and a trapezoidal baffle 518 is slidably installed inside the slot. One end of the trapezoidal baffle 518 is fixedly connected to the inner wall of the slot with a compression spring, and the other end of the trapezoidal baffle 518 overlaps with the surface of the filter screen 510. It should be noted that the outer wall of the recycling bin 1 has a cleaning groove, and a scraper that moves back and forth is movably installed on the upper part of the inner wall of the recycling bin 1. The scraper is set correspondingly to the cleaning groove. When the filter screen 510 moves, large unfiltered plastic particles on its surface are restricted to the position of the trapezoidal baffle 518, and the large plastic particles are removed by the back-and-forth moving scraper. This cleaning method is existing technology and will not be described in detail.

[0067] A one-way clutch is movably connected between the outer wall of the recycling bin 1 and the front end of the take-up roller 509. A synchronous pulley is fixedly connected to the driving end of the one-way clutch, and a synchronous belt 511 is movably disposed between the two synchronous pulleys. It should be noted that the one-way clutch prevents the take-up roller 509 from rotating on its own, and it can only rotate forward and backward with the synchronous belt 511, ensuring the stability of the take-up roller 509 in the process of winding and unwinding the filter screen 510.

[0068] In this embodiment, as Figures 1 to 16 As shown, the cleaning mechanism 6 includes a drive plate 601 that is vertically slidably disposed on the front side of the bracket of the recycling bin 1, and the middle part of the drive plate 601 overlaps with the outer peripheral wall of the cam 504. It should be noted that: the drive plate 601 is positioned above the cam 504, and the cam 504 is positioned at a 90-degree angle to a single tooth of the single-tooth bevel ring 505. The central angle corresponding to the "protruding section" of the cam 504 should fall entirely within the central angle corresponding to the "toothless section" of the single-tooth bevel ring 505, thus improving the stability of the timing during the filter cleaning process. Since both the cam 504 and the single-tooth bevel ring 505 are fixedly connected to the surface of the transmission rod 503, when the single-tooth bevel ring 505 meshes with the wedge-shaped toothed plate 506 and drives the filter 510, the cam 504 will not contact the drive plate 601. After the single tooth of the single-tooth bevel ring 505 disengages from the wedge-shaped toothed plate 506, the cam 504 contacts the drive plate 601 and drives the cleaning mechanism 6, so that the position switching and cleaning of the filter 510 are staggered, which can reduce the scratching between the surface of the cleaning plate 605 and the filter 510 and improve its service life.

[0069] Adjusting sleeves 602 are symmetrically fixedly connected to both sides of the drive plate 601, and push rods 603 are slidably arranged inside the adjusting sleeves 602. The two push rods 603 extend into the interior of the two cleaning chambers 508 respectively. A connecting rod 604 is hinged to the surface of the push rod 603, and a cleaning plate 605 that cooperates with the filter screen 510 is hinged to one end of the connecting rod 604. It should be noted that: several cleaning bristles that cooperate with the filter screen 510 are fixedly connected to the middle of the cleaning plate 605. When the cleaning plate 605 moves into the cleaning chamber 508, the cleaning bristles are inserted into the surface of the filter screen 510 after it has stopped operating, and the inside of the mesh of the filter screen 510 is cleaned.

[0070] A number of positioning nozzle rods 606 are fixedly connected to the surface of the cleaning plate 605, and a positioning air collecting sleeve 607 is movably inserted into one end of each positioning nozzle rod 606. One end of the air collecting sleeve 607 is fixedly connected to the inner wall of the cleaning chamber 508. It should be noted that the positioning nozzle rods 606 and the air collecting sleeve 607 guide the movement of the cleaning plate 605. When the cam 504 of the drive plate 601 is pushed upward, the adjusting sleeve 602 and the push rod 603 slide together, driving the push rod 603 to move towards the inside of the recovery box 1. Under the guidance of the positioning nozzle rods 606 and the air collecting sleeve 607, the push rod 603 drives the cleaning plate 605 to move horizontally inside the recovery chamber 517 and towards the filter screen 510 via the connecting rod 604. When the positioning nozzle rods 606 extend from inside the air collecting sleeve 607, they can spray gas, further improving the cleaning effect.

[0071] In this embodiment, as Figures 1 to 16 As shown, both ends of the drive plate 601 are fixedly connected to vertical rods 608. The drive plate 601 is fixedly connected to the adjusting sleeve 602 via the vertical rods 608. A support block 609 is slidably disposed on the surface of the vertical rod 608. One end of the support block 609 is fixedly connected to the side wall of the recycling box 1. A compression spring 610 is movably connected between the bottom of the support block 609 and the top of the adjusting sleeve 602. It should be noted that when the cam 504 releases contact with the drive plate 601, the compression spring 610 moves the drive plate 601 and the adjusting sleeve 602 downwards to reset.

[0072] The sidewall of the adjusting sleeve 602 is symmetrically provided with inclined grooves 611. Adjusting pins are symmetrically fixedly connected to the front end of the push rod 603. The push rod 603 is slidably disposed inside the inclined grooves 611 via the adjusting pins. An installation sleeve is slidably inserted into the other end of the push rod 603, and one end of the installation sleeve is fixedly connected to the inner wall of the recycling bin 1. It should be noted that when the drive plate 601 raises the adjusting sleeve 602, during the sliding process of the inclined grooves 611 and the adjusting pins, the push rod 603 moves towards the interior of the recycling bin 1.

[0073] In this embodiment, as Figures 1 to 16 As shown, a vent hole 612 is opened inside the positioning nozzle rod 606, and one end of the vent hole 612 extends into the interior of the air collecting sleeve 607. A piston ring is fixedly connected to the positioning nozzle rod 606 near the interior of the air collecting sleeve 607, and the positioning nozzle rod 606 slides inside the air collecting sleeve 607 through the piston ring. It should be noted that the fit clearance between the piston ring and the air collecting sleeve 607 is ≤0.02mm to ensure that the suction / jet pressure is ≥0.3MPa, which meets the mesh cleaning requirements. Furthermore, a return spring is movably connected between the side wall of the piston ring and the inner wall of the air collecting sleeve 607. When the drive plate 601 is disengaged from the cam 504, the return spring drives the positioning nozzle rod 606 to move back into the air collecting sleeve 607, thereby assisting the cleaning plate 605 in resetting.

[0074] One end of the gas collecting sleeve 607 is fixedly connected to a one-way valve nozzle 613, and an exhaust one-way valve 614 that mates with the one-way valve nozzle 613 is fixedly connected inside the positioning nozzle rod 606. A sealing ring that mates with the positioning nozzle rod 606 is fixedly connected to the middle of the gas collecting sleeve 607. It should be noted that the one-way valve nozzle 613 and the exhaust one-way valve 614 are set in opposite directions to ensure that one stably draws in air and the other stably exhausts air.

[0075] In this embodiment, as Figures 1 to 16 As shown, a method of using a recycling device for plastic casings of used automobile batteries includes the following steps:

[0076] S1. Core crushing operation process: Start the drive motor 3 to drive the corresponding crushing roller 2 to rotate. Under the meshing transmission of two sets of transmission gears 405, the two crushing rollers 2 rotate synchronously in opposite directions to crush the plastic shell of the waste automobile battery. The crushed plastic particles fall onto the surface of the filter screen 510. After being filtered and graded by the filter screen 510, they enter the subsequent recycling process.

[0077] S2. Adjustment Mechanism Linkage Control: During the operation of the drive motor 3, the left crushing roller 2 drives the transmission gear set 4 to rotate through the coordinated action of the synchronous transmission wheel and the transmission belt 406, causing the bevel gear rod 402 on the transmission gear set 4 to rotate synchronously. The bevel gear rod 402 and the front single-tooth bevel gear ring 505 form an intermittent meshing transmission. During this process, the rotating front single-tooth bevel gear ring 505 intermittently meshes with the wedge-shaped tooth plate 506, driving the wedge-shaped tooth plate 506 to slowly translate along the inside of the adjustment bracket 502. When the wedge-shaped tooth plate 506 translates to the end of the transmission pressure rod 507 on the inner wall of the adjustment bracket 502, since the wedge-shaped tooth plate 506 can only slide horizontally between the two guide rods 516, during the contact transmission process between the transmission pressure rod 507 and the inclined surface of the wedge-shaped tooth plate 506, the transmission pressure rod 507... 7. The fixedly connected adjusting bracket 502 slides along the two magnetic block rods 501 to complete the position adjustment of the adjusting bracket 502. At this time, the adjusting bracket 502 drives the telescopic transmission rod 503 to extend, so that the two sets of single-tooth bevel rings 505 on the surface of the transmission rod 503 switch the meshing state. The rear single-tooth bevel ring 505 forms a meshing transmission with the bevel rod 402, and the rear single-tooth bevel ring 505 moves to the top of the wedge-shaped tooth plate 506 with the adjustment bracket 502 and achieves meshing, thereby driving the wedge-shaped tooth plate 506 to move in the opposite direction. At this time, the front single-tooth bevel ring 505 disengages from the bevel rod 402 and the wedge-shaped tooth plate 506. Through the above transmission logic, the wedge-shaped tooth plate 506 and the adjusting sleeve 602 reciprocate at the side wall position of the recovery box 1 during the operation of the crushing roller 2.

[0078] S3. Filter surface switching: During the displacement of the wedge-shaped toothed plate 506, its bottom tooth surface meshes with the synchronous toothed roller 513. Through the meshing transmission between the synchronous toothed roller 513 and the synchronous gear rod 512, the synchronous belt 511 is driven to run. During the coordinated drive of the synchronous gear rod 512 and the synchronous belt 511, the two take-up rollers 509 achieve synchronous reciprocating rotation. At this time, the filter screen 510 between the two take-up rollers 509 reciprocates inside the recovery box 1, completing the positional switching of the effective filter surface of the filter screen 510, ensuring continuous and stable filtration efficiency.

[0079] S4. Filter cleaning mechanism operation: Since both cam 504 and single-tooth bevel ring 505 are fixedly connected to transmission rod 503, and the single teeth of cam 504 and single-tooth bevel ring 505 are offset at ninety degrees, when single-tooth bevel ring 505 disengages from wedge-shaped tooth plate 506, filter screen 510 stops operating, and cam 504 on transmission rod 503 rotates to the corresponding position on drive plate 601. After being squeezed by cam 504, drive plate 601 drives adjusting sleeve 602 to move upward along the side wall of recycling box 1. At this time, the inclined groove 611 on the side wall of the adjusting sleeve 602 and the adjusting pin at the end of the push rod 603 form a coordinated sliding, driving the push rod 603 to move into the recovery box 1. The push rod 603 drives the cleaning plate 605 through the hinged connecting rod 604 to move along the coordinated sliding direction of the positioning nozzle rod 606 and the air collecting sleeve 607, so that the cleaning bristles on the cleaning plate 605 are embedded in the surface of the filter screen 510 in the stopped state, and carry out targeted cleaning operations, significantly reducing the scratching wear between the cleaning bristles and the filter screen 510, and extending the service life of the components.

[0080] S5. Enhanced cleaning and cyclic operation: When the cleaning plate 605 drives the positioning nozzle rod 606 to extend from inside the air collecting sleeve 607, under the sealing transmission action of the piston ring, the gas inside the air collecting sleeve 607 is ejected through the end of the positioning nozzle rod 606 to perform a cleaning operation on the surface of the filter screen 510, further enhancing the cleaning efficiency. When the rotating cam 504 gradually disengages from the surface of the drive plate 601, the compression spring 610 drives the drive plate 601, the adjusting sleeve 602, and the push rod 603 to achieve a reset displacement. The cleaning plate 605 disengages from the filter screen 510 with the reset action. Subsequently, after the continuously rotating single-tooth bevel ring 505 re-engages with the wedge-shaped toothed plate 506, the winding roller 509 restarts and drives the filter screen 510 to wind up a certain stroke. Through the above-mentioned cyclic mechanism, the filter screen 510 is cleaned immediately after switching positions, ensuring the long-term stable operation of the filtration system.
