Description

Technical Field

[0001] This invention relates to the field of rotor grinding technology, specifically to a servo motor rotor grinding processing equipment with a positioning mechanism. Background Technology

[0002] The motor rotor is the core component of the motor that rotates with the magnetic field. It works with the stator to convert electrical energy into mechanical energy and is the key to output power. It generates electromagnetic torque under the action of the rotating magnetic field of the stator through electromagnetic induction (such as in asynchronous motors) or its own magnetic field (such as in synchronous motors), which drives the main shaft and external load to rotate. It needs to have sufficient mechanical strength, good electrical performance and dynamic balance accuracy. It is usually fixed on the main shaft and maintains a small air gap with the stator. Its performance directly affects the motor efficiency, power and applicable scenarios. Grinding the motor rotor is an important process to ensure its performance and stability. It mainly focuses on precision machining of the rotor surface to eliminate defects generated during manufacturing or use (such as burrs, out-of-roundness, wear, etc.) and ensure uniform air gap between the rotor and stator, rotational balance and assembly accuracy.

[0003] In the grinding process of servo motor rotors, the grinding depth varies in different areas. After the grinding function is adjusted to the appropriate grinding depth, it is often affected by external forces, resulting in slight displacement that is difficult to observe with the naked eye and affecting the grinding effect. Therefore, we propose a servo motor rotor grinding equipment with a positioning mechanism. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a servo motor rotor grinding processing equipment with a positioning mechanism, including a hollow base frame, a concave frame plate fixedly connected to the top of the hollow base frame, an electric clamp fixedly connected to the inner side of the concave frame plate, a straight electric slide rail fixedly connected to the inner wall of the hollow base frame, a grinding depth positioning device slidably connected to the top of the straight electric slide rail, and a grinding device fixedly connected to the top of the grinding depth positioning mechanism;

[0005] The grinding depth positioning device includes a frame-type slide plate. A drive motor is fixedly connected to one side of the frame-type slide plate. The drive shaft of the drive motor passes through the frame-type slide plate and is fixedly connected to an internal threaded rod. A sleeve-type slider is sleeved and threadedly connected to the outside of the internal threaded rod. A positioning slide plate is fixedly connected to the top of the sleeve-type slider. A positioning elongated hole is opened on one side of the positioning slide plate. A vertical fixing plate is fixedly connected to the top of the frame-type slide plate. A positioning insert rod passes through and is slidably connected to one side of the vertical fixing plate. When the positioning insert rod moves inward, it is inserted into the positioning elongated hole on the side of the positioning slide plate to position the positioning slide plate. This prevents the positioning slide plate, which has been adjusted to the grinding depth, from being slightly offset by external forces during grinding, which is difficult to observe with the naked eye and affects the grinding effect.

[0006] The hollow base frame is configured as a hollow frame body with multiple rectangular holes on the surface, and the bottom of the grinding depth positioning device is slidably connected to the top of the hollow base frame.

[0007] The bottom of the frame-type slide plate is slidably connected to the top of the straight electric slide rail, the bottom of the frame-type slide plate is slidably connected to the top of the hollow base frame, and the top of the frame-type slide plate is fixedly connected to the grinding device.

[0008] The end of the built-in threaded rod away from the drive motor is rotatably connected to the inner wall of the frame slide plate through a rotating bolt. The outer side of the sleeve slider is slidably connected to the inner wall of the frame slide plate. Multiple positioning rods are provided, and the multiple positioning rods are distributed on the vertical fixing plate.

[0009] One end of the positioning rod is fixedly connected to a long pull plate, and a retraction spring is fixedly connected to the side of the long pull plate near the positioning rod. By setting a retraction spring between the vertical fixed plate and the long pull plate, the positioning rod is always kept in the positioning long hole, preventing the positioning rod from gradually leaving the positioning long hole due to external force during long-term grinding, which would result in poor positioning effect. An arc-shaped long cover plate is fixedly connected to the top of the long pull plate. By setting an arc-shaped long cover plate on one side of the long pull plate, the retracted retraction spring is covered and protected, preventing the flying debris generated by grinding from accumulating on the surface of the retracted retraction spring, which is difficult to handle and affects the use.

[0010] The end of the retraction spring away from the long pull plate is fixedly connected to one side of the vertical fixed plate. Multiple retraction springs are provided, and each of the multiple retraction springs is sleeved on the positioning insert.

[0011] Furthermore, the grinding device includes a concave connecting plate. A sanding belt cleaning mechanism is fixedly connected to the bottom of the inner wall of the concave connecting plate. A limiting rod is slidably connected through one side of the concave connecting plate. An elliptical connecting block is sleeved and fixedly connected to the outer side of the limiting rod. A threaded rod is rotatably connected through one side of the elliptical connecting block via a bearing. The threaded rod facilitates disassembly and installation after the sanding belt is damaged due to prolonged use, preventing inconvenience in replacement when the sanding belt is difficult to repair after prolonged grinding, thus affecting the grinding process. A cross connecting plate is sleeved and slidably connected to the outer side of the threaded rod. An electric roller is rotatably connected to one side of the cross connecting plate via a rotating bolt. A sanding belt is sleeved and belt-connected to the outer side of the electric roller. An arc-shaped fixing device is fixedly connected to the outer side of the cross connecting plate. The rod has an inner support square plate fixedly connected to one end of the arc-shaped fixing rod away from the cross connecting plate. By setting the inner support square plate fixedly connected to the arc-shaped fixing rod on the inner side of the sanding belt, the inner side of the sanding belt is stabilized by an inner support shape, preventing the sanding belt from sinking and deforming inward when it continues to deepen the sanding depth, making it difficult to effectively carry out deep sanding. The inner support square plate scrapes and cleans the surface of the rotating electric roller, preventing sanding debris from adhering to the surface of the electric roller and getting stuck between the sanding belt, affecting the transmission effect. The bottom of the concave connecting plate is fixedly connected to the top of the frame sliding plate. One end of the limiting long rod passes through the cross connecting plate and is slidably connected to the cross connecting plate. Multiple inner support square plates are provided, and the multiple inner support square plates are respectively distributed between the two electric rollers at the position where they are in contact with the inner side of the sanding belt.

[0012] Furthermore, the belt sander cleaning mechanism includes an inclined bottom plate, which guides the cleaned debris into a concave cassette, preventing it from falling off the concave connecting plate and becoming difficult to collect. A frame scraper is fixedly connected to the top of the inclined bottom plate, which scrapes the bottom surface of the sanding belt to prevent excessive sanding debris from adhering to the surface and affecting subsequent sanding processes. An internal frame plate is fixedly connected to the inner wall of the frame scraper, and a top-mounted brush is fixedly connected to the top of the internal frame plate. The top-mounted brush performs friction cleaning on the bottom surface of the sanding belt to remove particles and debris that the frame scraper fails to remove, preventing some particles from adhering to the bottom surface of the sanding belt. The scraper failed to completely remove debris, affecting the subsequent grinding effect. Side sealing plates are fixedly connected to both sides of the inclined base plate, and a concave clamping plate is fixedly connected to the bottom of the inclined base plate. A concave clamping box is slidably connected to the inner wall of the concave clamping plate. The interlocking action between the concave clamping plate and the concave clamping box facilitates the centralized cleaning of accumulated debris, preventing excessive debris buildup in the concave clamping box from overflowing outwards and becoming difficult to handle. Side sealing plates are fixedly connected to both sides of the concave clamping box. The bottom of the inclined base plate is fixedly connected to the inner wall of the concave connecting plate, and the bottom of the side sealing plate is fixedly connected to the inner wall of the concave connecting plate. Two concave clamping plates are provided, and the two concave clamping plates are distributed at the bottom of the inclined base plate.

[0013] This invention provides a servo motor rotor grinding and processing equipment with a positioning mechanism. It has the following beneficial effects:

[0014] 1. This servo motor rotor grinding equipment with a positioning mechanism uses a positioning rod to insert into the positioning hole on the side of the positioning slide plate when it moves inward. This prevents the positioning slide plate, which has been adjusted to the grinding depth, from being slightly offset by external forces during grinding, thus affecting the grinding effect. An inner support square plate, which is fixedly connected to an arc-shaped fixing rod, is installed on the inner side of the grinding belt to stabilize its shape. This prevents the grinding belt from concave and deforming inward when it continues to deepen the grinding depth, making it difficult to effectively perform deep grinding. A frame scraper cleans the bottom surface of the grinding belt by scraping, preventing excessive grinding debris from adhering to the surface of the grinding belt and affecting the subsequent grinding effect.

[0015] 2. This servo motor rotor grinding equipment with a positioning mechanism is equipped with a grinding depth positioning device. When the positioning rod moves inward, it is inserted into the positioning elongated hole on the side of the positioning slide to position the positioning slide. This prevents the positioning slide, which has been adjusted for grinding depth, from being slightly offset by external forces during grinding, which is difficult to observe with the naked eye and affects the grinding effect. By setting a retraction spring between the vertical fixed plate and the long pull plate, the positioning rod is kept in the positioning elongated hole at all times. This prevents the positioning rod from gradually leaving the positioning elongated hole due to external forces during long-term grinding, which would result in poor positioning effect. By setting an arc-shaped long cover plate on one side of the long pull plate, the retracting retraction spring is covered and protected, preventing the flying debris generated during grinding from accumulating on the surface of the retracting retraction spring, which is difficult to handle and affects the use.

[0016] 3. This servo motor rotor grinding equipment with a positioning mechanism is equipped with a grinding device. An inner support square plate, fixedly connected to an arc-shaped fixing rod, is installed inside the grinding belt to stabilize its shape. This prevents the grinding belt from deforming inwards as the grinding depth increases, hindering effective deep grinding. The inner support square plate scrapes and cleans the surface of the rotating electric roller, preventing grinding debris from adhering to the roller and getting trapped between the grinding belts, thus affecting transmission. The threaded long rod facilitates disassembly and installation after prolonged use and damage to the grinding belt, preventing inconvenience and inconvenience in replacing the belt after prolonged grinding.

[0017] 4. This servo motor rotor grinding equipment with a positioning mechanism is equipped with a sanding belt cleaning mechanism. The frame scraper scrapes the bottom surface of the sanding belt to prevent excessive sanding debris from adhering to the surface and affecting the subsequent grinding effect. The top brush performs friction cleaning on the bottom surface of the sanding belt to remove particles and debris that the frame scraper cannot remove, preventing some particles and debris from being completely scraped off by the frame scraper and affecting the subsequent grinding effect. The inclined bottom plate guides the cleaned debris into the concave cassette to prevent the cleaned debris from falling from the concave connecting plate and being difficult to collect. The interlocking cooperation between the concave cassette and the concave cassette facilitates the centralized cleaning of accumulated debris and prevents excessive debris from accumulating in the concave cassette and overflowing outwards, which is difficult to handle.

Detailed Implementation

[0027] 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.

[0028] Please see Figures 1-4The present invention provides a servo motor rotor grinding processing equipment with a positioning mechanism, including a hollow base frame 1, a concave frame plate 2 fixedly connected to the top of the hollow base frame 1, an electric clamp 3 fixedly connected to the inner side of the concave frame plate 2, a straight electric slide rail 4 fixedly connected to the inner wall of the hollow base frame 1, a grinding depth positioning device 5 slidably connected to the top of the straight electric slide rail 4, and a grinding device 6 fixedly connected to the top of the grinding depth positioning mechanism.

[0029] The grinding depth positioning device 5 includes a frame slide plate 501. A drive motor 502 is fixedly connected to one side of the frame slide plate 501. The drive shaft of the drive motor 502 passes through the frame slide plate 501 and is fixedly connected to an internal threaded rod 503. A sleeve slider 504 is sleeved on the outside of the internal threaded rod 503 and threadedly connected to it. A positioning slide plate 505 is fixedly connected to the top of the sleeve slider 504. A positioning elongated hole 506 is opened on one side of the positioning slide plate 505. A vertical fixing plate 507 is fixedly connected to the top of the frame slide plate 501. A positioning insert rod 508 passes through and is slidably connected to one side of the vertical fixing plate 507.

[0030] The hollow base frame 1 is configured as a hollow frame body with multiple rectangular holes on the surface, and the bottom of the grinding depth positioning device 5 is slidably connected to the top of the hollow base frame 1.

[0031] The bottom of the frame-type skateboard 501 is slidably connected to the top of the straight electric slide rail 4, the bottom of the frame-type skateboard 501 is slidably connected to the top of the hollow base frame 1, and the top of the frame-type skateboard 501 is fixedly connected to the grinding device 6.

[0032] The end of the built-in threaded rod 503 away from the drive motor 502 is rotatably connected to the inner wall of the frame slide plate 501 through a rotating bolt. The outer side of the sleeve slider 504 is slidably connected to the inner wall of the frame slide plate 501. Multiple positioning rods 508 are provided, and the multiple positioning rods 508 are distributed on the vertical fixed plate 507.

[0033] One end of the positioning rod 508 is fixedly connected to a long pull plate 509, a retraction spring 510 is fixedly connected to the side of the long pull plate 509 near the positioning rod 508, and an arc-shaped long cover plate 511 is fixedly connected to the top of the long pull plate 509.

[0034] One end of the retraction spring 510 away from the long pull plate 509 is fixedly connected to one side of the vertical fixed plate 507. Multiple retraction springs 510 are provided, and multiple retraction springs 510 are respectively sleeved on the positioning rod 508. In use, the rotor to be ground is placed between two electric clamps 3. The electric clamps 3 clamp it and drive the rotor to rotate at high speed. Then, the grinding device 6 is driven to contact the rotor surface for grinding by the grinding depth positioning device 5. The grinding depth of the rotor is controlled by adjusting the distance between the grinding device 6 and the center of the rotor by the grinding depth positioning device 5. At the same time, the grinding length of the rotor surface can be controlled by driving the grinding depth positioning device 5 to move laterally by the straight electric slide rail 4.

[0035] When the rotor is clamped and rotating at high speed, pull the positioning rod 508 outward via the long pull rod until it no longer affects the movement of the positioning slide plate 505. Start the drive motor 502 to drive the internal threaded rod 503 to rotate. When the internal threaded rod 503 rotates, it engages with the sleeve slider 504 on the inner wall of the frame slide plate 501, causing the sleeve slider 504 to move. As the sleeve slider 504 moves, it drives the top positioning slide plate 505 to move. As the positioning slide plate 505 moves, it drives the top grinding device 6 to move. When the grinding device 6 moves with the positioning slide plate 505 to contact the rotor, it can grind the rotor surface. When different areas of the rotor surface need to be ground to different depths, drive the positioning slide plate 505 with the internal threaded rod 503 to move the grinding device 6 to the appropriate depth. Then release the long pull plate 509. At this time, the return spring... 510 uses a retraction force to move the long pull plate 509 and the positioning rod 508 inward. When the positioning rod 508 moves inward, it inserts into the positioning elongated hole 506 on the side of the positioning slide plate 505 to position the positioning slide plate 505. By setting a retraction spring 510 between the vertical fixing plate 507 and the long pull plate 509, the positioning rod 508 is always located in the positioning elongated hole 506. When the long pull plate 509 moves towards the vertical fixing plate 507 with the retraction force of the retraction spring 510, it drives the top arc-shaped long cover plate 511 to move together. The arc-shaped long cover plate 511 moves with the long pull plate 509 until it touches the vertical fixing plate 507 and stops. At this time, the arc-shaped long cover plate 511 covers the retraction spring 510 on one side of the long pull plate 509. The arc-shaped long cover plate 511 on one side of the long pull plate 509 provides a covering protection for the retracted retraction spring 510.

[0036] Please see Figures 1-8This invention provides a servo motor rotor grinding processing equipment with a positioning mechanism: the grinding device 6 includes a concave connecting plate 601, a sanding belt cleaning mechanism 602 is fixedly connected to the bottom of the inner wall of the concave connecting plate 601, a limiting rod 603 is slidably connected through one side of the concave connecting plate 601, an elliptical connecting block 604 is sleeved and fixedly connected to the outer side of the limiting rod 603, a threaded rod 605 is rotatably connected through one side of the elliptical connecting block 604 via a bearing, a cross connecting plate 606 is slidably connected to the outer side of the threaded rod 605, and an electric motor is rotatably connected to one side of the cross connecting plate 606 via a rotating bolt. A circular roller 607 is fitted on the outside of an electric circular roller 607 and connected by a belt to a frosting belt 608. An arc-shaped fixing rod 609 is fixedly connected to the outside of a cross connecting plate 606. An inner support square plate 610 is fixedly connected to the end of the arc-shaped fixing rod 609 away from the cross connecting plate 606. The bottom of the concave connecting plate 601 is fixedly connected to the top of the frame-type sliding plate 501. One end of the limiting long rod 603 passes through the cross connecting plate 606 and is slidably connected to the cross connecting plate 606. Multiple inner support square plates 610 are provided, and the multiple inner support square plates 610 are respectively distributed between the two electric circular rollers 607 at the position where they are in contact with the inner side of the frosting belt 608.

[0037] The belt sander cleaning mechanism 602 includes an inclined base plate 6021, a frame scraper 6022 fixedly connected to the top of the inclined base plate 6021, an inner frame plate 6023 fixedly connected to the inner wall of the frame scraper 6022, a top-mounted brush 6024 fixedly connected to the top of the inner frame plate 6023, side sealing square plates 6025 fixedly connected to both sides of the inclined base plate 6021, a concave clamping plate 6026 fixedly connected to the bottom of the inclined base plate 6021, a concave clamping box 6027 slidably connected to the inner wall of the concave clamping plate 6026, side connecting sealing plates 6028 fixedly connected to both sides of the concave clamping box 6027, the bottom of the inclined base plate 6021 fixedly connected to the inner wall of the concave connecting plate 601, and the bottom of the side sealing square plate 6025 fixedly connected to the inner wall of the concave connecting plate 601. The wall is fixedly connected, and two concave clamping plates 6026 are provided, which are distributed at the bottom of the inclined bottom plate 6021. In use, when the positioning slide plate 505 moves, it drives the top concave connecting plate 601 to move. The movement of the concave connecting plate 601 drives the inner wall sanding belt cleaning mechanism 602, the inner cross connecting plate 606, the electric roller 607, and the sanding belt 608 to move together until the sanding belt 608 moves to contact the rotor surface and begins to sand the rotor surface. The inner support square plate 610, which is fixedly connected to the arc-shaped fixing rod 609, is provided on the inner side of the sanding belt 608 to stabilize the inner side of the sanding belt 608. At the same time, the rotation of the electric roller 607 can drive the sanding belt 608 to rotate. 08. As the electric roller 607 rotates, it contacts the bottom sanding belt cleaning mechanism 602. At this time, the sanding belt cleaning mechanism 602 cleans the outer surface of the abrasive belt 608. The outer surface of the electric roller 607 is constantly in contact with the inner support plate 610 as it rotates. The inner support plate 610 scrapes and cleans the surface of the rotating electric roller 607. If the abrasive belt 608 is difficult to repair and continue to be used after a long period of use, the threaded rod 605 is rotated from one side of the elliptical connecting block 604 to engage with the threaded part of the concave connecting plate 601. Under the through-limiting of the limiting rod 603, it moves outward towards the concave connecting plate 601 until the end of the threaded rod 605 away from the elliptical connecting block 604 reaches a distance from the inner side of the concave connecting plate 601 and then stops. The abrasive belt 608 can be removed from the electric roller 607 and then taken out from the area between the threaded rod 605 and the inner side of the concave connecting plate 601. The threaded rod 605 facilitates disassembly and installation of the abrasive belt 608 after prolonged use and damage. As the electric roller 607 rotates, the bottom surface of the abrasive belt 608 contacts the frame scraper 6022 and the top brush 6024. The frame scraper 6022 scrapes and cleans the bottom surface of the abrasive belt 608, while the top brush 6024 performs friction cleaning to remove particles and debris that the frame scraper 6022 fails to remove. The removed debris falls onto the inclined bottom plate 6021 and slides down the inclined surface into the concave card box 6027 for storage.The removed debris is guided into the concave card box 6027 by the inclined bottom plate 6021. When too much debris accumulates in the concave card box 6027, it is pushed upwards until it disengages from the concave card plate 6026, at which point the concave card box 6027 can be removed for cleaning. After cleaning, the concave card box 6027 can be re-engaged into the concave card plate 6026. The engagement between the concave card plate 6026 and the concave card box 6027 facilitates the centralized cleaning of accumulated debris.

[0038] When using this invention, the rotor to be ground is placed between two electric clamps 3. The electric clamps 3 clamp the rotor and drive it to rotate at high speed. Then, the grinding depth positioning device 5 drives the grinding device 6 to contact the rotor surface for grinding. The grinding depth of the rotor is controlled by adjusting the distance between the grinding device 6 and the center of the rotor. At the same time, the grinding length of the rotor surface is controlled by driving the grinding depth positioning device 5 to move laterally through the straight electric slide rail 4.

[0039] When the rotor is clamped and rotating at high speed, the positioning rod 508 is pulled outward via the long pull rod until it no longer affects the movement of the positioning slide plate 505. The drive motor 502 is then started, driving the internal threaded rod 503 to rotate. As the internal threaded rod 503 rotates, it engages with the sleeve slider 504 on the inner wall of the frame slide plate 501, causing the sleeve slider 504 to move. The movement of the sleeve slider 504 moves the top positioning slide plate 505, which in turn moves the top grinding device 6. The grinding device 6, moving with the positioning slide plate 505 until it contacts the rotor, begins grinding the rotor surface. When different depths of grinding are required on different areas of the rotor surface, the internal threaded rod 508 is pulled outward via the long pull rod 508. 03. The driving positioning slide plate 505 moves the grinding device 6 to a suitable depth, and then the long pull plate 509 is released. At this time, the return spring 510 drives the long pull plate 509 and the positioning rod 508 to move inward through the return force. When the positioning rod 508 moves inward, it inserts into the positioning elongated hole 506 on the side of the positioning slide plate 505 to position the positioning slide plate 505. By setting the return spring 510 between the vertical fixing plate 507 and the long pull plate 509, the positioning rod 508 is always located in the positioning elongated hole 506. When the long pull plate 509 moves towards the vertical fixing plate 507 with the return force of the return spring 510, it drives the top arc-shaped long cover plate 511 to move together. The arc-shaped long cover plate 511 moves with the long pull plate 509 to a position where it is aligned with the grinding device 6. When the vertical fixing plate 507 comes into contact with the rotor, it stops. At this time, the arc-shaped long cover plate 511 covers the top of the retraction spring 510 on one side of the long pull plate 509. The arc-shaped long cover plate 511 on one side of the long pull plate 509 provides a covering protection for the retracted retraction spring 510. When the positioning slide plate 505 moves, it drives the top concave connecting plate 601 to move. The movement of the concave connecting plate 601 drives the inner wall sanding belt cleaning mechanism 602, the inner cross connecting plate 606, the electric roller 607, and the abrasive belt 608 to move together until the abrasive belt 608 moves to contact the rotor surface and begins to grind the rotor surface. The abrasive belt 608 is protected by an inner support square plate 610 fixedly connected to the arc-shaped fixing rod 609. The inner side is stabilized by an internal support structure. Simultaneously, the abrasive belt 608 rotates via an electric roller 607. As the electric roller 607 rotates, the abrasive belt 608 contacts the bottom sanding mechanism 602, which cleans the outer surface of the abrasive belt 608. The outer surface of the electric roller 607 is constantly in contact with the inner support plate 610, which scrapes and cleans the surface of the rotating electric roller 607. If the abrasive belt 608 becomes unusable after prolonged use, the threaded rod 605 is rotated from one side of the elliptical connecting block 604 to engage with the threaded connection of the concave connecting plate 601. Under the limiting influence of the limiting rod 603, it moves outward from the concave connecting plate 601.The abrasive belt 608 is removed from the electric roller 607 and taken out from the area between the threaded rod 605 and the inner side of the concave connecting plate 601, until the threaded rod 605 moves away from the end of the elliptical connecting block 604. The threaded rod 605 facilitates disassembly and installation of the abrasive belt 608 after prolonged use and damage. As the electric roller 607 rotates, the bottom surface of the abrasive belt 608 contacts the frame scraper 6022 and the top brush 6024. The frame scraper 6022 scrapes the bottom surface of the abrasive belt 608, while the top brush 6024 performs a friction cleaning. The scraper removes particles and debris that the frame scraper 6022 fails to remove. The removed debris falls onto the inclined bottom plate 6021 and slides down the inclined surface into the concave card box 6027 for storage. The inclined bottom plate 6021 guides the removed debris into the concave card box 6027. When too much debris accumulates in the concave card box 6027, it is pushed upwards until it disengages from the concave card plate 6026, at which point the concave card box 6027 can be removed for cleaning. After cleaning, the concave card box 6027 can be re-engaged into the concave card plate 6026. The engagement between the concave card plate 6026 and the concave card box 6027 facilitates the centralized cleaning of accumulated debris.
