Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic wire cutting and processing, and in particular to a corona-resistant special electromagnetic wire processing and cutting device for transformers. Background Art

[0002] Electromagnetic wire is an insulated wire used to make coils or windings in electrical products, also known as winding wire. Electromagnetic wire must meet a variety of usage and manufacturing process requirements. The former includes its shape, specifications, ability to work at high temperatures for a short time or a long time, and withstand strong vibrations and centrifugal forces at high speeds in certain occasions, withstand corona and breakdown at high voltages, and resist chemical corrosion in special atmospheres. Anti-corona special electromagnetic wire is an electromagnetic wire with excellent corona resistance. It is mainly used in equipment such as variable frequency motors to extend the service life of the motor. In addition to excellent insulation and high strength characteristics, this anti-corona special electromagnetic wire can also improve partial discharge performance. Electromagnetic wire cutting refers to the process of cutting the electromagnetic wire to a certain length. In actual applications, the electromagnetic wire may need to be cut into a specific length due to different needs.

[0003] Since the electromagnetic wire has a certain degree of stretchability and elasticity, when cutting the electromagnetic wire at a certain point, if it is not tightened and fixed at all times, the thrust of cutting may push the electromagnetic wire to bend and deform, resulting in the electromagnetic wire not being cut smoothly or being cut incompletely. Therefore, we proposed a special anti-corona electromagnetic wire processing and cutting equipment for transformers. Summary of the invention

[0014] The bottom of the pushing plate is fixedly connected with an arc scraper, and when the arc scraper is bent and slid outward on the side concave plate, it scrapes and cleans the inner bottom surface of the side concave plate to prevent dust and other debris from accumulating on the inner bottom surface of the side concave plate and affecting the compaction of the electromagnetic wire. A frosting block is provided on one side of the arc scraper, and multiple frosting blocks are arranged on the side of the arc scraper to increase the static friction when the electromagnetic wire is compressed, so as to prevent the electromagnetic wire from being pulled toward the center position when the thrust during cutting is too large, resulting in poor cutting effect. A curved circular hole is provided on one side of the arc scraper, and a bottom square is fixedly connected at the center of the bottom of the pushing plate, and side push rods are fixedly connected at both sides of the bottom square. Side push rods are arranged at the center of the bottom of the pushing plate to resist the arc scrapers on both sides of the bottom square, so that the arc scraper is always in an outwardly inclined state, so as to prevent the arc scraper from bending inward when being pushed because the outer oblique curvature is small after bending and recovery.

[0015] There are two arc-shaped scrapers, and the two arc-shaped scrapers are evenly distributed at the bottom of the push plate;

[0016] There are multiple sanding blocks, and the multiple sanding blocks are evenly distributed on one side of the arc scraper. There are multiple arc surface circular holes, and the multiple arc surface circular holes are evenly distributed on one side of the arc scraper. The electromagnetic wire passes through the wire hole on one side of the side concave plate and then passes through the wire hole opened on the cutting device and the side concave plate on the other side in sequence.

[0017] Furthermore, the cutting device comprises a rectangular frame, both sides of which are fixedly connected with concave clamping plates, and the concave clamping plates are arranged in the middle of the rectangular frame to resist and limit the pressing plates, so as to prevent the electromagnetic wire from bending first when the moving distances of the upper and lower pressing plates are inconsistent, resulting in poor subsequent cutting effect. The top and bottom of the rectangular frame are fixedly connected with electric push rods, and the driving shaft of the electric push rod is fixedly connected with an adaptive cutter, and the electromagnetic wire is completely cut off by the adaptive cutting blade by respectively setting the adaptive cutting blade to a tip cutting surface and a square groove for facilitating the insertion of the tip cutting surface, so as to prevent the electromagnetic wire from being completely cut off by the tip squeezing force of the two cutting blades when the cutting blade is not sharp after repeated use.

The top of the pressing plate is fixedly connected with a limiting through rod, and the limiting through rod fixed to the pressing plate and penetrating the side long plate limits the direction of the pressing plate to prevent the pressing plate and the extension spring from being elastically connected and tilted and stuck due to uneven force when the electromagnetic wire is pressed. A side groove is provided at the bottom of the pressing plate, and a rectangular long hole is provided at the top of the pressing plate. The top of the rectangular frame is fixedly connected to the bottom of the T-shaped sliding bar. Two adapter cutters are provided, and the two adapter cutters are respectively distributed on the inner side of the rectangular frame.

[0018] Furthermore, the cleaning mechanism includes an I-shaped scraper, and the rotating I-shaped scraper scrapes and cleans the top and bottom surfaces of the pressing plate to prevent dust and other debris from being attached to the pressure surface where the pressing plate contacts the electromagnetic wire, resulting in a certain gap between the two pressing plates, making it difficult to press the electromagnetic wire. A longer rectangular hole is provided in the middle of the pressing plate to facilitate the discharge of dust and other debris at the center of the I-shaped scraper, and to prevent dust and other debris from being continuously accumulated near the center of the I-shaped scraper when the speed of the I-shaped scraper is too slow, making it difficult to discharge. A small motor is fixedly connected to the top of the I-shaped scraper, and arc-shaped brushes are fixedly connected to both sides of the I-shaped scraper. The rotating arc The arc-shaped brush rubs and cleans the top and bottom surfaces of the pressing plate to prevent dust particles that cannot be completely scraped off by the I-shaped scraper from remaining on the top and bottom surfaces of the pressing plate. The I-shaped scraper is fixedly connected with corrugated scrapers on both sides away from the small motor. When the corrugated scraper rotates, it will contact the surface of the extension spring and scrape off the dust particles and other debris on its surface to prevent dust and other debris from being mixed between the spring coils after the extension spring is used for a long time, affecting the spring contraction performance.

A plurality of arc-shaped brushes are provided, and the plurality of arc-shaped brushes are evenly distributed on both sides of the I-shaped scraper.

[0019] The present invention has the beneficial effects:

[0020] 1. The push plate of the present invention applies pressure to the arc-shaped scraper through the pushing force so that the electromagnetic wire is tightly compacted on the inner bottom surface of the side concave plate, preventing the thrust of cutting from pushing the electromagnetic wire to bend and deform, resulting in failure to cut smoothly or incomplete cutting of the electromagnetic wire. The adapting cutting blade is respectively set to a tip cutting surface and a square groove for facilitating the insertion of the tip cutting surface so that the electromagnetic wire is completely cut by the adapting cutting blade, preventing the cutting blade from becoming less sharp after repeated use, and the extrusion pressure of the tips of the two cutting blades from making it difficult to completely cut and truncate the electromagnetic wire. The rotating I-shaped scraper scrapes and cleans the top and bottom surfaces of the pressing plate, preventing dust and other debris from adhering to the pressure surface where the pressing plate contacts the electromagnetic wire, resulting in a certain gap between the two pressing plates, making it difficult to press the electromagnetic wire.

[0021] 2. The present invention provides a clamping device, and when the arc-shaped scraper blade bends and slides outward on the side concave plate, it scrapes and cleans the inner bottom surface of the side concave plate, thereby preventing dust and other debris from accumulating on the inner bottom surface of the side concave plate and affecting the compaction of the electromagnetic wire. The pushing plate applies pressure to the arc-shaped scraper blade through the pushing force so that the electromagnetic wire is compacted on the inner bottom surface of the side concave plate, thereby preventing the thrust of cutting from pushing the electromagnetic wire to bend and deform, resulting in failure to cut the electromagnetic wire smoothly or incompletely. By arranging multiple frosting blocks on the side of the arc-shaped scraper blade, the static friction force existing when the electromagnetic wire is compressed is increased, thereby preventing the electromagnetic wire from being pulled toward the center position when the thrust during cutting is too large, resulting in poor cutting effect. A side support rod is arranged at the center of the bottom of the pushing plate to resist the arc-shaped scrapers on both sides of the bottom block, so that the arc-shaped scraper blade is always in an outwardly inclined state, thereby preventing the arc-shaped scraper blade from bending inwardly when being pushed because the outward oblique curvature is small after the bending recovery.

[0022] 3. The present invention provides a cutting device, and respectively provides the adapting cutting blade as a tip cutting surface and a square groove for facilitating the insertion of the tip cutting surface so that the electromagnetic wire is completely cut by the adapting cutting blade, so as to prevent the cutting blade from becoming less sharp after repeated use, and the extrusion force of the tips of the two cutting blades from being difficult to completely cut and cut the electromagnetic wire. The pressing plates above and below the electromagnetic wire simultaneously press the electromagnetic wire tightly, so as to prevent the surface of the electromagnetic wire close to the cutting blade from being subjected to a certain degree of ductility due to the thrust when the electromagnetic wire is cut and cut by the thrust, resulting in poor cutting effect of the electromagnetic wire. A concave clamping plate is provided in the middle of the rectangular frame to limit the pressing plate against the contact, so as to prevent the upper and lower pressing plates from bending the electromagnetic wire first when the moving distances are inconsistent, resulting in poor subsequent cutting effect. The limiting through rod fixed to the pressing plate and passing through the side long plate limits the direction of the pressing plate, so as to prevent the pressing plate from being elastically connected to the extension spring and being tilted and stuck due to uneven force when pressing the electromagnetic wire.

[0023] 4. The present invention provides a cleaning mechanism, and the rotating I-shaped scraper scrapes and cleans the top and bottom surfaces of the pressing plate to prevent dust and other debris from adhering to the pressure surface where the pressing plate contacts the electromagnetic wire, resulting in a certain gap between the two pressing plates, making it difficult to press the electromagnetic wire; the rotating arc-shaped brush frictionally cleans the top and bottom surfaces of the pressing plate to prevent a large number of dust particles that cannot be completely scraped off by the I-shaped scraper from remaining on the top and bottom surfaces of the pressing plate; the corrugated scraper contacts the surface of the extension spring when rotating and scrapes away the dust particles and other debris on its surface, preventing a large amount of dust and other debris from being mixed between the spring coils after the extension spring is used for a long time, affecting the contraction performance of the spring; a longer rectangular hole is provided in the middle position of the pressing plate to facilitate the discharge of dust and other debris at the center position of the I-shaped scraper, and to prevent a part of dust and other debris from continuously accumulating near the center of the I-shaped scraper when the rotation speed of the I-shaped scraper is too slow, making it difficult to discharge.

[0038] A cutting device 6, which is used to cut the electromagnetic wire at any position where it needs to be cut;

[0039] One side of the side concave plate 1 is fixedly connected to one side of the electric slide rail 3, two side concave plates 1 are provided, and the two side concave plates 1 are respectively distributed on both sides of the electric slide rail 3, the bottom of the side concave plate 1 is fixedly connected to the top of the bottom column 2, the inner side of the electric slide rail 3 is slidably connected to the top of the T-shaped slide bar 4, the inner side of the side concave plate 1 is fixedly connected to the top of the clamping device 5, and the bottom of the T-shaped slide bar 4 is fixedly connected to the top of the cutoff device 6;

[0040] Wherein, the pressing device 5 comprises:

[0041] A push plate 501, which is used to tightly press the two ends of the electromagnetic wire that has been tightened on the side concave plate 1, and a hydraulic push rod 502 is arranged on the top of the push plate 501;

[0042] The top of the push plate 501 is fixedly connected to the driving shaft of the hydraulic push rod 502, and the top of the hydraulic push rod 502 is fixedly connected to the inner side of the side concave plate 1;

[0043] A wire hole 7 is provided on the inner side of the side concave plate 1, and the inner wall bottom surface of the wire hole 7 is flush with the inner bottom surface of the side concave plate 1;

[0044] The bottom of the push plate 501 is fixedly connected with an arc scraper 503, one side of the arc scraper 503 is provided with a grinding block 504, one side of the arc scraper 503 is provided with an arc surface circular hole 505, the bottom center of the push plate 501 is fixedly connected with a bottom block 506, and both sides of the bottom block 506 are fixedly connected with side support rods 507;

[0045] There are two arc-shaped scrapers 503, and the two arc-shaped scrapers 503 are evenly distributed at the bottom of the push plate 501;

[0046] There are multiple sanding blocks 504, and the multiple sanding blocks 504 are evenly distributed on one side of the arc scraper 503. There are multiple arc surface circular holes 505, and the multiple arc surface circular holes 505 are evenly distributed on one side of the arc scraper 503. When in use, the electromagnetic wire passes through the wire hole 7 on one side of the side concave plate 1 and then passes through the cutting device 6 and the wire hole 7 opened on the other side of the side concave plate 1 in sequence. After the electromagnetic wire successfully passes through the two wire holes 7, it is tightened, and then the two ends of the electromagnetic wire are tightly pressed together by the pressing device 5. After the electromagnetic wire is pressed, the T-shaped slide bar 4 can be adjusted by the electric slide rail 3 to drive the cutting device 6 to move to the position where the electromagnetic wire needs to be cut. The electromagnetic wire is cut off by cutting, and the electromagnetic wire passing through the two wire holes 7 is tightened and adjusted to not be at the bottom center of the push plate 501, and the hydraulic push rod 502 is started to push the push plate 501 downward to move. When the push plate 501 moves downward, it drives the arc scraper 503 at the bottom to move downward together. When the arc scraper 503 moves downward, it contacts the inner bottom surface of the side concave plate 1 and continues to bend and slide outward under the thrust. When the arc scraper 503 bends and slides outward on the side concave plate 1, it scrapes and cleans the inner bottom surface of the side concave plate 1. The push plate 501 continues to move downward to push the arc scraper 503 to bend until the arc scraper 503 is close to one side of the bottom block 506.

When the arc scraper 503 is about to contact the bottom surface of the side concave plate 1, the side grinding block 504 contacts the electromagnetic wire and the inner bottom surface of the side concave plate 1. By arranging multiple grinding blocks 504 on the side of the arc scraper 503, the static friction force existing when the electromagnetic wire is compressed is increased. The multiple arc surface circular holes 505 opened on the arc scraper 503 are convenient for observing the electromagnetic wire under the arc scraper 503. After the electromagnetic wire is cut off, the hydraulic push rod 502 drives the push rod 504 to push the electromagnetic wire. When the pressure plate 501 moves back upward, the arc scraper 503 moves up together with the pushing plate 501. When the arc scraper 503 moves up, it bends and recovers toward the bottom block 506. A side support rod 507 is set at the bottom center of the pushing plate 501 to resist the arc scraper 503 on both sides of the bottom block 506 so that the arc scraper 503 is always in a state of tilting outward. Here, the length of the bottom block 506 and the radius thickness of the side support rod 507 should be set shorter than the height of the sanding block 504 to avoid the sanding block 504 from contacting with the inner bottom surface of the side concave plate 1 as the pushing plate 501 moves downward.

[0047] For the second embodiment, please refer to Figure 1-Figure 8The present invention provides a corona-resistant special electromagnetic wire processing and cutting device for transformers: the cutting device 6 comprises a rectangular frame 601, both sides of the rectangular frame 601 are fixedly connected with a concave clamping plate 602, the top and bottom of the rectangular frame 601 are fixedly connected with an electric push rod 603, the driving shaft of the electric push rod 603 is fixedly connected with an adapting cutter 604, both sides of the adapting cutter 604 are fixedly connected with a side long plate 605, the top of the side long plate 605 is fixedly connected with a cleaning mechanism 606, the bottom of the side long plate 605 is fixedly connected with an extension spring 607, the bottom of the extension spring 607 is fixedly connected with a pressing plate 608, the top of the pressing plate 608 is fixedly connected with a cleaning mechanism 606, and the bottom of the side long plate 605 is fixedly connected with a stretching spring 607.

[0048] The cleaning mechanism 606 includes an I-shaped scraper 6061, a small motor 6062 is fixedly connected to the top of the I-shaped scraper 6061, arc-shaped brushes 6063 are fixedly connected to both sides of the I-shaped scraper 6061, and corrugated scrapers 6064 are fixedly connected to both sides of the I-shaped scraper 6061 away from the small motor 6062. The output end of the small motor 6062 is fixedly connected to the top of the side long plate 605. There are multiple arc-shaped brushes 6063, and the multiple arc-shaped brushes 6063 are evenly distributed on both sides of the I-shaped scraper 6061. When in use, after the electromagnetic wire is pressed, the T-shaped slide bar 4 can be adjusted by the electric slide rail 3 to drive the rectangular frame 601 to move to the position where the electromagnetic wire needs to be cut, and the electric push rod 603 pushes the adapter cutting blade in the direction of the electromagnetic wire. The adapting cutting blade is provided with two adapter cutting blades which are respectively distributed at the top and bottom of the inner side of the rectangular frame 601. The adapting cutting blade near the inner bottom of the rectangular frame 601 is a sharp cutting surface. The bottom of the adapting cutting blade near the inner top of the rectangular frame 601 is provided with a square groove which is convenient for the tip of the bottom adapting cutting blade to be inserted. By respectively setting the adapting cutting blade to the sharp cutting surface and the square groove which is convenient for the tip cutting surface to be inserted, the electromagnetic wire is completely cut off by the adapting cutting blade. The adapting cutting blade moves to drive the side long plates 605 on both sides to move. When the side long plates 605 move, the bottom pressing plates 608 are driven to move together through the extension springs 607. When the pressing plates 608 gradually move toward the direction of the electromagnetic wire, they contact the electromagnetic wire. The pressing plates 608 above and below the electromagnetic wire simultaneously tighten the electromagnetic wire. When the pressing plate 608 moves toward the direction of the electromagnetic wire, the side slots 610 on both sides will be engaged with the concave clamping plate 602, and the concave clamping plate 602 is set in the middle of the rectangular frame 601 to limit the pressing plate 608. After the two pressing plates 608 press the electromagnetic wire, the adapter cutting blade continues to move in the direction of the electromagnetic wire to cut it. At this time, the side long plate 605 moves with the adapter cutting blade, and the side long plate 605 compresses the extension spring 607. The limiting rod 609 fixed to the pressing plate 608 and passing through the side long plate 605 limits the direction of the pressing plate 608. After the electromagnetic wire is cut and cut, the side long plate 605 and other components are driven by the electric push rod 603 to move back upward. When the electromagnetic wire is cut by the troops The pressing plate 608 can be driven downward by the electric push rod 603 until the side groove 610 of the pressing plate 608 contacts and engages with the concave clamping plate 602, and then the side long plate 605 is pushed. When the side long plate 605 is pushed, the small motor 6062 on the top is driven to move downward together. When the small motor 6062 moves downward, it drives the I-shaped scraper 6061 on the bottom to move downward until the I-shaped scraper 6061 moves down to the inside of the rectangular long hole 611 and stops at the middle position of the rectangular long hole 611. At this time, the small motor 6062 is started to drive the I-shaped scraper 6061 to rotate. When the I-shaped scraper 6061 rotates, the inner side surface is always in contact with the top and bottom surfaces of the pressing plate 608. The rotating I-shaped scraper 6061 scrapes and cleans the top and bottom surfaces of the pressing plate 608.When the I-shaped scraper 6061 rotates, it drives the arc brushes 6063 and the corrugated scraper 6064 on both sides to rotate together. When the arc brushes 6063 rotate, they are in contact with the top and bottom surfaces of the pressing plate 608 at all times. The rotating arc brushes 6063 rub and clean the top and bottom surfaces of the pressing plate 608. When the I-shaped scraper 6061 is located in the rectangular long hole 611, the extension spring 607 is also gradually compressed. At this time, the rotating corrugated scraper 6064 will contact the surface of the extension spring 607. When 6064 rotates, it will contact the surface of the extension spring 607 and scrape away the dust particles and other debris on its surface. A part of the dust and other debris scraped by the I-shaped scraper 6061 will be discharged from the outside of the pressing plate 608, and the dust and other debris near the center of the I-shaped scraper 6061 will be scraped into the rectangular long hole 611 and fall downward through the rectangular long hole 611. By opening a longer rectangular long hole 611 in the middle of the pressing plate 608, it is convenient for the dust and other debris at the center of the I-shaped scraper 6061 to be discharged.

[0049] When the present invention is in operation, the electromagnetic wire is passed through the wire hole 7 on one side of the side recessed plate 1 and then sequentially passed through the cutting device 6 and the wire hole 7 opened on the side recessed plate 1 on the other side. After the electromagnetic wire successfully passes through the two wire holes 7, it is tightened, and then the two ends of the electromagnetic wire are tightly pressed together by the pressing device 5. After the electromagnetic wire is pressed, the electric slide rail 3 can be used to adjust the T-shaped slide bar 4 to drive the cutting device 6 to move to the position where the electromagnetic wire needs to be cut, and the electromagnetic wire is cut by cutting. After the electromagnetic wire passing through the two wire holes 7 is tightened and adjusted to not be at the bottom center of the push plate 501, the hydraulic push rod 502 is started to push the push plate 501 downward to move. When the push plate 501 moves downward, it drives the arc-shaped scraper 503 at the bottom to move downward together. When the arc-shaped scraper 503 moves downward The arc scraper 503 contacts the inner bottom surface of the side concave plate 1 and continues to bend and slide outward under the thrust. The arc scraper 503 scrapes and cleans the inner bottom surface of the side concave plate 1 when it bends and slides outward on the side concave plate 1. The pushing plate 501 continues to move downward to push the arc scraper 503 to bend until the side of the arc scraper 503 close to the bottom block 506 is completely in contact with the inner bottom surface of the side concave plate 1 and stops. At this time, the pushing plate 501 applies pressure to the arc scraper 503 through the pushing force so that the electromagnetic wire is tightly pressed on the inner bottom surface of the side concave plate 1. When the arc scraper 503 is about to contact the bottom surface of the side concave plate 1, the side grinding block 504 contacts the electromagnetic wire and the inner bottom surface of the side concave plate 1. By arranging multiple grinding blocks 504 on the side of the arc scraper 503, the electromagnetic wire is increased. The static friction force existing during compression and the multiple arc-surface circular holes 505 opened on the arc-shaped scraper blade 503 facilitate observation of the electromagnetic wire below the arc-shaped scraper blade 503. After the electromagnetic wire is cut off, the hydraulic push rod 502 drives the push plate 501 to move back upward. When the push plate 501 moves back upward, the arc-shaped scraper blade 503 moves up together. When the arc-shaped scraper blade 503 moves up, it bends and recovers toward the bottom block 506. Side push rods 507 are set at the bottom center of the push plate 501 to resist the arc-shaped scraper blades 503 on both sides of the bottom block 506, so that the arc-shaped scraper blade 503 is always in an outwardly inclined state. Here, the length of the bottom block 506 and the radius thickness of the side push rods 507 should be set shorter than the height of the sanding block 504 to avoid the push plate 501 from contacting with the sanding block 504 when it moves downward. The inner bottom surface of the side concave plate 1 is in conflict, so that the grinding block 504 is difficult to completely contact with the inner bottom surface of the side concave plate 1. After the electromagnetic wire is compressed, the electric slide rail 3 can be used to adjust the T-shaped slide bar 4 to drive the rectangular frame 601 to move to the position where the electromagnetic wire needs to be cut and cut. The electric push rod 603 pushes the adaptor cutting blade to move in the direction of the electromagnetic wire. The adaptor cutting blade is provided with two top and bottom portions respectively distributed near the inner side of the rectangular frame 601. The adaptor cutting blade near the inner bottom of the rectangular frame 601 is a tip cutting surface. The bottom of the adaptor cutting blade near the inner top of the rectangular frame 601 is provided with a square groove for facilitating the insertion of the tip of the bottom adaptor cutting blade. By respectively setting the adaptor cutting blade to the tip cutting surface and the square groove for facilitating the insertion of the tip cutting surface, the electromagnetic wire is completely cut by the adaptor cutting blade.The adapting cutting blade moves to drive the side long plates 605 on both sides to move. When the side long plates 605 move, the bottom pressing plates 608 are driven to move together through the extension spring 607. When the pressing plates 608 gradually move in the direction of the electromagnetic wire, they come into contact with the electromagnetic wire. The pressing plates 608 above and below the electromagnetic wire simultaneously press the electromagnetic wire tightly. When the pressing plates 608 move in the direction of the electromagnetic wire, the side card slots 610 opened on both sides will be engaged with the concave card plate 602. The concave card plate 602 is set in the middle of the rectangular frame 601 to limit the pressing plates 608. After the two pressing plates 608 press the electromagnetic wire, the adapting cutting blade continues to move in the direction of the electromagnetic wire to cut it. At this time, the side long plates 605 As the adaptor cutting blade moves together, the side long plate 605 compresses the extension spring 607, and the limiting through rod 609 fixed to the pressing plate 608 and penetrating the side long plate 605 limits the direction of the pressing plate 608. After the electromagnetic wire is cut and cut, the side long plate 605 and other components are driven to move back upward by the electric push rod 603. When the electromagnetic wire is cut, the pressing plate 608 can be driven downward by the electric push rod 603 until the side slot 610 of the pressing plate 608 is in contact with the concave card plate 602 and continues to push the side long plate 605. When the side long plate 605 is pushed, it drives the small motor 6062 on the top to move downward together. When the small motor 6062 moves downward, it drives the bottom I-shaped The scraper 6061 moves downward until the I-shaped scraper 6061 moves downward to the inside of the rectangular long hole 611 and stops at the middle position of the rectangular long hole 611. At this time, the small motor 6062 is started to drive the I-shaped scraper 6061 to rotate. When the I-shaped scraper 6061 rotates, the inner side surface is always in contact with the top and bottom surfaces of the pressing plate 608. The rotating I-shaped scraper 6061 scrapes and cleans the top and bottom surfaces of the pressing plate 608. When the I-shaped scraper 6061 rotates, it drives the arc-shaped brushes 6063 and the corrugated scraper 6064 on both sides to rotate together. When the arc-shaped brushes 6063 rotate, they are always in contact with the top and bottom surfaces of the pressing plate 608. The rotating arc-shaped brushes 6063 rub and clean the top and bottom surfaces of the pressing plate 608 When the I-shaped scraper 6061 is located in the rectangular long hole 611, the extension spring 607 is also gradually compressed. At this time, the rotating wave scraper 6064 will contact the surface of the extension spring 607. When the wave scraper 6064 rotates, it will contact the surface of the extension spring 607 and scrape away the dust particles and other debris on its surface. A part of the dust and other debris scraped by the I-shaped scraper 6061 is discharged from the outside of the pressing plate 608, and the dust and other debris near the center of the I-shaped scraper 6061 is scraped into the rectangular long hole 611 and falls downward through the rectangular long hole 611. By opening a longer rectangular long hole 611 in the middle of the pressing plate 608, it is convenient for the dust and other debris at the center of the I-shaped scraper 6061 to be discharged.
