The present invention provides a chip removal device, and the outer diameter of the annular rubber ring is set to be the same as the outer diameter of the spiral tube, so as to prevent the annular rubber ring from being squeezed by iron sheets and other debris and failing to completely seal it when inserted into the spiral tube. The annular rubber ring plastically expands and fits in contact with the inner wall of the spiral tube, so as to prevent the inner wall of the spiral tube from being unsealed, resulting in the cleaned iron chips penetrating into the spiral tube from the annular rubber ring and being difficult to be taken out. The corrugated soft board protects the parts wrapped by it, and prevents a large amount of iron chips in the spiral tube from falling on the surface of the parts wrapped by the corrugated soft board and affecting their use. The three external connecting rods always support the corrugated soft board and the annular rubber ring in contact, so as to prevent the annular rubber ring from being squeezed by iron sheets and other debris and bending and tilting when entering the spiral tube.

A place on the top of the inner wall of the corrugated soft board is bulged upward by the top impact of the rounded corner rotating rod, so that the iron filings on the top thereof slide to both sides, thereby preventing a part of the cleaned iron filings from adhering to the top of the corrugated soft board and being difficult to be discharged to both sides, affecting its expansion and contraction. Various places on the top of the corrugated soft board are continuously bulged by the top impact of the rounded corner rotating rod, thereby preventing the iron filings at various places on the top of the corrugated soft board from being completely cleaned and still affecting its expansion and contraction. The corrugated soft board is hit by the gravity block to generate shaking for chip removal, thereby preventing a small amount of iron filings from being attached to the outer surface of the corrugated soft board except the top and being difficult to handle.

[0023] 5. The present invention provides a lubrication mechanism. When the annular arc piece is not squeezed and pushed, it contacts the inner wall of the plastic air cushion and blocks the seepage holes of the inner wall to prevent the lubricant from being impregnated near the seepage holes of the inner wall of the plastic air cushion, which is easy to adhere to dust and iron filings. When the annular arc piece is pushed, it breaks away from the contact with the plastic air cushion and no longer blocks the seepage holes to prevent the annular rubber ring from squeezing the plastic air cushion and blocking the seepage holes of the inner wall of the plastic air cushion to make it difficult to drain. The outer surfaces of the annular rubber ring and the corrugated soft plate are impregnated with lubricating oil to reduce the friction between the annular rubber ring and the corrugated soft plate and the iron filings to prevent the annular rubber ring and the corrugated soft plate from being damaged by long-term friction with the iron filings and becoming difficult to use. When the annular arc piece moves back, it slides and scrapes the inner wall of the plastic air cushion to prevent a large amount of iron filings from adhering to the seepage holes of the inner wall of the plastic air cushion to block them and make it difficult to discharge the lubricating oil.

When in use, the spiral tube 8 is placed in the storage circular hole 7, and the spiral tube 8 is pushed to move until its pipe mouth contacts one side of the cleaning device 5. Before cleaning the pipe mouth, the chip removal device 6 is adjusted to move to the inside of the spiral tube 8. At this time, the electric roller 1 is started to rotate and drive the spiral tube 8 in contact with it to rotate together. When the spiral tube 8 rotates, the curved bottom plate 3 at the bottom supports its bottom to stabilize the spiral tube 8 from being pressed and tilted during rotation. At the same time, one side of the cleaning device 5 is in friction contact with the pipe mouth of the rotating spiral tube 8 for cleaning. After cleaning, After that, the chip removal device 6 can be adjusted to move back to the outside of the spiral tube 8 to bring out the iron chips accumulated inside the spiral tube 8. Before starting the electric roller 1 to drive the spiral tube 8 to rotate, the position of the two first nuts 503 away from the fixed large nut 501 is first adjusted by thread matching.

When the rounded corner rotating rod 6023 gradually rotates to a vertical position, it will punch the top of the inner wall of the corrugated soft plate 606, so that a place on the top of the inner wall of the corrugated soft plate 606 bulges upward. A place on the top of the inner wall of the corrugated soft plate 606 is bulged upward by the punching of the rounded corner rotating rod 6023, so that the iron filings on its top slide to both sides. When the rounded corner rotating rod 6023 rotates to a vertical state, it continues to be pushed by the outer connecting rod 605 to move toward the large disc 601. When the rounded corner rotating rod 6023 moves, it drives the annular slide plate 6022 on one side to move together, and the annular slide plate 6022 sleeve It is arranged to slide on the electric telescopic rod 604, and the electric telescopic rod 604 limits the side thrust spring 6021 through the annular slide plate 6022 to prevent the side thrust spring 6021 from bending and deflecting due to uneven force. When the annular slide plate 6022 moves, it compresses the side thrust spring 6021 on one side, and when the rounded rotating rod 6023 moves, it constantly punches the corrugated soft plate 606, so that bulges appear at various places on the top of the corrugated soft plate 606 in turn. The top of the corrugated soft plate 606 is continuously bulged by the top punching of the rounded rotating rod 6023. When the rounded rotating rod 6023 moves toward the large disc 601, the motor 10 is started to drive the large disc 601 to rotate. The rotation of the large disc 601 drives the side thrust spring 6021 and the annular slide plate 6022 on one side to rotate. The rotation of the shaped slide plate 6022 drives the rounded corner rotating rod 6023 on one side to rotate. When the rounded corner rotating rod 6023 rotates to the bottom, the gravity block 6025 on the inner wall of the side hole 6024 falls downward due to gravity. After the gravity block 6025 falls downward, it collides with the corrugated soft plate 606. The corrugated soft plate 606 is hit by the gravity block 6025 to vibrate and remove debris. When the outer connecting rod 605 is driven to move into the spiral tube 8 by the electric telescopic rod 604, the side push spring 6021 pushes the annular slide plate 6022 to move into the spiral tube 8 through the extension force. The movement of the annular slide plate 6022 drives the rounded corner rotating rod 6023 on one side to move together. When the annular arc piece 6035 is not pushed by extrusion, it contacts the inner wall of the plastic air cushion 6033 and blocks the seepage hole 6034 on the inner wall.When the circular rotating rod moves back, a part of the raised surface of the corrugated soft plate 606 is pushed to contact and squeeze the plastic air cushion 6033. A part of the raised surface of the corrugated soft plate 606 passes through the squeezed plastic air cushion 6033 and pushes the annular arc piece 6035 at its bottom to the side of the plastic air cushion 6033 close to the side connecting rod 6031. The annular arc piece 6035 is pushed and bent inward. When the annular arc piece 6035 is pushed, it breaks away from the contact with the plastic air cushion 6033 and no longer blocks the seepage hole 6034. When the annular rubber ring 607 moves to the side of the annular baffle 6032 when it contacts the plastic air cushion 6033 as the outer connecting rod 605 moves back. The lubricating oil in the plastic air cushion 6033 is squeezed and discharged to the outer surface of the annular rubber ring 607 and the corrugated soft plate 606 through the seepage hole 6034. The outer surface of the annular rubber ring 607 and the corrugated soft plate 606 is impregnated with lubricating oil to reduce the friction between the iron filings and the rounded corner rotating rod 6023 is pushed by the side thrust spring 6021 to move toward the spiral tube 8 and pass through the plastic air cushion 6033. The side of the annular arc piece 6035 away from the annular baffle 6032 slides along the surface of the plastic air cushion 6033 and moves back to restore to the initial state. When the annular arc piece 6035 moves back, it slides and scrapes the inner wall of the plastic air cushion 6033.

[0050] When the present invention is operated and used, the spiral tube 8 is placed in the storage circular hole 7, and the spiral tube 8 is pushed to move until its tube mouth contacts one side of the cleaning device 5. Before cleaning the tube mouth, the chip removal device 6 is adjusted to move into the spiral tube 8. At this time, the electric roller 1 is started to rotate to drive the spiral tube 8 in contact with it to rotate together. When the spiral tube 8 rotates, the curved bottom plate 3 at the bottom supports its bottom to stabilize the spiral tube 8 from being pressed and tilted during rotation. At the same time, one side of the cleaning device 5 is in friction contact with the tube mouth of the rotating spiral tube 8 for cleaning. After cleaning, the iron filings accumulated in the spiral tube 8 can be taken out by adjusting the chip removal device 6 to move back to the outside of the spiral tube 8. Before starting the electric roller 1 to drive the spiral tube 8 to rotate, the two first nuts are first adjusted by thread matching. 503 is located at a distance from the fixed large nut 501. When the two first nuts 503 are away from the fixed large nut 501, the long bolt 502 can be manually slid to drive the circular iron brush 504 on the surface to move. The second nuts 505 on both sides of the circular iron brush 504 are fixed on the long bolt 502 and the circular iron brush 504 is stuck therein. At this time, the position of the circular iron brush 504 away from the pipe mouth of the spiral tube 8 can be adjusted by sliding the long bolt 502. After adjusting the circular iron brush 504 to move to contact the surface of the spiral tube 8, it moves a short distance to squeeze the corrugated scraper 507. When the spiral tube 8 rotates, its pipe mouth is in friction contact with the circular iron brush 504 and the corrugated scraper 507 on one side, and the circular iron brush 504 rubs and cleans the pipe mouth of the rotating spiral tube 8. , the corrugated scraper 507 on one side of the circular iron brush 504 scrapes and cleans the pipe mouth of the spiral tube 8. When the rotating spiral tube 8 contacts the squeezed corrugated scraper 507, the corrugated scraper 507 is squeezed and drives the corrugated bar 508 on the surface to tilt outward and pierce between the circular iron brushes 504. When the spiral tube 8 rotates, the residual iron filings on the uneven surface drive the corrugated scraper 507 to move. When the corrugated scraper 507 moves, it drives the corrugated bar 508 on the surface to move together. When the corrugated bar 508 moves, it moves and combs the inside of the circular iron brush 504. The annular inclined plate 506 on the side of the circular iron brush 504 away from the spiral tube 8 resists the iron filings cleaned by friction. Before cleaning the spiral tube 8, the driving shaft of the electric telescopic rod 604 is used. The extension drives the outer connecting rod 605 to move into the spiral tube 8. When the outer connecting rod 605 moves, it drives the corrugated soft plate 606 at one end to extend. When the corrugated soft plate 606 extends, it drives the annular rubber ring 607 on the outer surface to move together. The outer diameter of the annular rubber ring 607 is set to be the same as the outer diameter of the spiral tube 8. When the annular rubber ring 607 moves to contact the tube mouth of the spiral tube 8, it is driven by the corrugated soft plate 606 to be squeezed with the spiral tube 8 and is gradually inserted into the spiral tube 8. The squeezed annular rubber ring 607 plastically expands and contacts with the inner wall of the spiral tube 8 at all times. The iron filings that are cleaned and dropped into the spiral tube 8 are accumulated between the corrugated soft plate 606 and the inner wall of the spiral tube 8. The corrugated soft plate 606 blocks the iron filings from the outside and protects the components wrapped by it.The three outer connecting rods 605 always support the corrugated soft plate 606 and the annular rubber ring 607, and the outer connecting rod 605 is driven to move back to the outside of the spiral tube 8 through the electric telescopic rod 604. When the outer connecting rod 605 moves back, the corrugated soft plate 606 on the outer surface is driven to shrink. When the corrugated soft plate 606 shrinks, the annular rubber ring 607 on the outer surface is driven to move out of the spiral tube 8. When the annular rubber ring 607 moves out, the iron filings accumulated between the corrugated soft plate 606 and the inner wall of the spiral tube 8 are taken out together. When the outer connecting rod 605 continues to move back, it contacts the chip removal mechanism 602 and pushes the chip removal mechanism 602 to rotate upward. At the same time, when the outer connecting rod 605 moves back, it drives the annular rubber ring 607 to move to contact the lubrication mechanism 603 and squeeze the lubrication mechanism 603, so that the lubrication mechanism The lubricating oil in the structure 603 is squeezed out on the surface of the annular rubber ring 607 and the corrugated soft plate 606. The rounded corner rotating rods 6023 are set to three like the outer connecting rods 605, and the three rounded corner rotating rods 6023 are on the same horizontal line as the three outer connecting rods 605. The rounded corner rotating rods 6023 and the outer connecting rods 605 are set to be aligned with each other. When the outer connecting rod 605 moves back, it contacts the rounded corner rotating rods 6023 and pushes the rounded corner rotating rods 6023 to rotate upward. When the rounded corner rotating rods 6023 gradually rotate to the vertical position, they will punch the top of the inner wall of the corrugated soft plate 606, so that the top of the inner wall of the corrugated soft plate 606 bulges upward. The top of the inner wall of the corrugated soft plate 606 is bulged upward by the top of the rounded corner rotating rods 6023, so that the iron filings on the top slide to both sides. When it rotates to the vertical state, it continues to be pushed by the outer connecting rod 605 to move toward the large disc 601. When the rounded corner rotating rod 6023 moves, it drives the annular slide plate 6022 on one side to move together. The annular slide plate 6022 is sleeved on the electric telescopic rod 604 to slide. The electric telescopic rod 604 limits the side thrust spring 6021 through the annular slide plate 6022 to prevent the side thrust spring 6021 from bending and deflecting due to uneven force. When the annular slide plate 6022 moves, it compresses the side thrust spring 6021 on one side. When the rounded corner rotating rod 6023 moves, it constantly pushes against the corrugated soft plate 606, so that bulges appear at various places on the top of the corrugated soft plate 606 in turn. The top of the corrugated soft plate 606 continues to bulge due to the push of the rounded corner rotating rod 6023. When the rounded corner rotating rod 6023 moves toward the large disc 601, the motor 10 is started to drive the large disc 601 to rotate. The rotation of the large disc 601 drives the side thrust spring 6021 and the annular slide plate 6022 on one side to rotate. The rotation of the annular slide plate 6022 drives the rounded corner rotating rod 6023 on one side to rotate. When the rounded corner rotating rod 6023 rotates to the bottom, the gravity block 6025 on the inner wall of the side square hole 6024 falls downward due to gravity. After the gravity block 6025 falls downward, it collides with the corrugated soft plate 606. The corrugated soft plate 606 is hit by the gravity block 6025 to shake and remove chips. When the outer connecting rod 605 is driven to move into the spiral tube 8 through the electric telescopic rod 604, the side thrust spring 6021 pushes the annular slide plate 6022 to move into the spiral tube 8 through the extension force.The movement of the annular slide plate 6022 drives the rounded rotating rod 6023 on one side to move together. When the annular arc piece 6035 is not squeezed and pushed, it contacts the inner wall of the plastic air cushion 6033 and blocks the seepage hole 6034 on the inner wall. When the circular rotating rod moves back, it pushes a part of the raised surface of the corrugated soft plate 606 to contact and squeeze the plastic air cushion 6033. A part of the raised surface of the corrugated soft plate 606 passes through the squeezed plastic air cushion 6033 and pushes the annular arc piece 6035 at its bottom to the side of the plastic air cushion 6033 close to the side connecting rod 6031. The annular arc piece 6035 is pushed and bent and tilted inward. When the annular arc piece 6035 is pushed, it breaks away from the contact with the plastic air cushion 6033 and no longer blocks the seepage hole 6034. The annular rubber ring 607 moves along with the outer When the connecting rod 605 moves back and contacts the plastic air cushion 6033, it squeezes it toward the side of the annular baffle 6032. The lubricating oil in the plastic air cushion 6033 is squeezed and discharged outward through the seepage hole 6034 to the outer surface of the annular rubber ring 607 and the corrugated soft plate 606. The outer surface of the annular rubber ring 607 and the corrugated soft plate 606 is impregnated with lubricating oil to reduce the friction between the iron filings. When the rounded corner rotating rod 6023 is pushed by the side thrust spring 6021 to move toward the spiral tube 8 and pass through the plastic air cushion 6033, the side of the annular arc piece 6035 away from the annular baffle 6032 slides along the surface of the plastic air cushion 6033 and moves back to restore to the initial state. When the annular arc piece 6035 moves back, it slides and scrapes the inner wall of the plastic air cushion 6033.
