Description

Technical Field

[0001] This invention relates to the field of coal mining machine guide rail grinding technology, and in particular to an automated testing and grinding unit applicable to various types of coal mining machine guide rails. Background Technology

[0002] The guide rail of a coal mining machine is a key traveling component. Used for extended periods in the complex and harsh conditions underground, its surface suffers from severe rust and oxidation fatigue due to coal dust erosion, humid environment corrosion, and mechanical friction. Furthermore, during the repair process after wear and damage, cold welding is required to overlay the damaged areas, leaving behind a large amount of weld slag and oxide scale. To ensure the assembly accuracy, smooth travel, and service life of the guide rail, these surface defects and residual impurities must be thoroughly ground and cleaned to remove rust, oxide layers, and weld slag, bringing the guide rail surface to the specified precision and cleanliness requirements.

[0003] Currently, the traditional grinding and cleaning of coal mining machine guide rails mainly involves manual grinding, with workers using tools such as wire brushes to grind the surface of the guide rails. This method has many drawbacks: firstly, manual grinding is inefficient and labor-intensive, making it difficult to meet the grinding needs of large batches and various types of coal mining machine guide rails; secondly, the grinding process generates a large amount of dust, which easily enters the wire brush bristles and is difficult to clean. As the grinding operation continues, the dust gradually accumulates inside the bristles, reducing the subsequent grinding effect.

[0004] Therefore, an automated testing and grinding unit suitable for various types of coal mining machine guide rails is provided to address the above issues. Summary of the Invention

[0010] Preferably, a disc is fixed on the movable rod, and a sealing gasket is fixed on the disc; an inner ring is fixed on the inner wall of the first end tube, and when the first end tube is not inserted into the first port, the sealing gasket is attached to one side of the inner ring, the diameter of the disc is smaller than the inner diameter of the first end tube, and the diameter of the disc is larger than the inner diameter of the inner ring.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0017] The positive and progressive effects of this invention are as follows: The aforementioned automated detection and grinding unit, applicable to guide rails of various types of coal mining machines, detects the guide rails through a detection mechanism. Combined with a translation mechanism and an adjustment mechanism, it drives the brush roller to move along the trajectory generated by the detection. In conjunction with a drive mechanism, it drives the brush roller to rotate, achieving automated grinding of rust, oxide layer, and welding slag on the guide rail surface. This significantly improves grinding efficiency and quality, reduces manual labor intensity, and adapts to the grinding needs of various types of guide rails. Simultaneously, clean airflow is introduced into the brush roller through an air supply pipe. The airflow is sprayed out through a narrow groove on the roller, blowing the dust inside the bristles outward. This, combined with the dust suction strip of the dust suction unit, simultaneously removes dust from the outside of the bristles, forming a dual cleaning structure of "internal blowing and external suction." This completely eliminates the problem of dust accumulation and difficulty in cleaning inside the bristles, ensuring the continuous grinding effect of the brush roller.

[0018] The shielding mechanism, through the linkage between the power unit, the first end pipe, and the air supply pipe, automatically drives the shielding strip to cover and close the narrow groove during guide rail grinding operations, preventing grinding dust from entering the roller through the narrow groove. When it is necessary to clean the brush bristles, the first end pipe is connected to the first port of the air supply pipe, and the power unit automatically drives the shielding strip to leave the narrow groove, opening the narrow groove and ensuring that the clean airflow can be sprayed out smoothly. This achieves automated control of the opening and closing of the narrow groove without manual operation.

[0019] The sealing ring inside the first port fits and seals with the first end tube. During the brush cleaning process, the brush roller rotates, causing the first end tube to rotate on the sealing ring. Through the linkage between the oil injection mechanism and the first end tube, lubricating oil is automatically injected into the oil drain hole of the sealing ring when the first end tube is inserted into the first port. The lubricating oil is evenly distributed on the surface of the sealing ring, effectively reducing frictional loss between the end plate and the sealing ring and preventing the sealing ring from being damaged due to long-term friction.

[0020] An opening and closing mechanism is provided, which, through the linkage of the elastic telescopic component and the push bar, works with the transmission unit to drive the cover to flip. When the first end tube is inserted into the first port, the cover is automatically driven to open without affecting the normal connection between the two. When the first end tube is separated from the first port, the cover is automatically driven to reset and close, sealing the first port and effectively preventing dust and foreign objects generated during the grinding process from entering the air supply pipe.

Detailed Implementation

[0023] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0024] like Figures 1-12 As shown, an automated testing and grinding unit suitable for multi-variety coal mining machine guide rails includes a base 1; a conveying mechanism 3 and a testing mechanism 2 are respectively provided on both sides of the base 1; and a material-carrying roller conveyor 4 is installed on the top of the base 1.

[0025] It also includes a translation mechanism 5 installed between the base 1 and the material conveyor 4; the translation mechanism 5 is connected to a stand 502 via a frame 501, the stand 502 is equipped with an adjustment mechanism, and the adjustment mechanism is equipped with an end plate 8.

[0026] A drive mechanism 10 is installed on the end plate 8, and the drive mechanism 10 is connected to a brush roller 7.

[0027] The brush roller 7 includes a roller 701 and brush bristles 702 fixed on the circumferential surface of the roller 701; a plurality of narrow grooves 703 arranged in a ring array are provided on the circumferential surface of the roller 701; one end of the roller 701 is fixedly connected to a first end tube 704, and the first end tube 704 is rotatably mounted on the end plate 8.

[0028] One end of the first end tube 704 is aligned with an air supply pipe 11, and the end of the air supply pipe 11 is provided with a first port 1101 for the first end tube 704 to be inserted into.

[0029] The roller 701 is provided with a blocking mechanism 13, and the blocking mechanism 13 is connected to a power unit. The power unit is used to drive the blocking mechanism 13 to cover or leave the narrow groove 703.

[0030] like Figure 1 As shown, the conveying mechanism 3 includes a guide rail 301 and an RGV trolley 302 mounted on the guide rail 301; the RGV trolley 302 is provided with a conveying roller conveyor 303.

[0031] The conveying mechanism 3 is used to transport the workpiece to be ground to the material carrier roller 4. Specifically, the workpiece is transported to the conveying roller 303, and the RGV trolley 302 moves towards the base 1 via the guide rail 301. After the conveying roller 303 is connected to the material carrier roller 4, the conveying roller 303 transports the workpiece to the material carrier roller 4, thus completing the conveying and loading of the workpiece.

[0032] After the workpiece is ground on the material carrier roller 4, it is transported onto the conveyor roller 303 via the material carrier roller 4. The RGV trolley 302 moves the workpiece away from the base 1 and moves it to the position of the guide rail 301 away from the base 1. The processed workpiece is then removed and the workpiece to be processed is transported onto the conveyor roller 303 for the processing of the next workpiece.

[0033] Both the loading roller conveyor 4 and the conveying roller conveyor 303 mentioned above are roller conveyors.

[0034] like Figure 1 As shown, the detection mechanism 2 includes a robotic arm 201 and a detector 202 installed at the end of the robotic arm 201; the detector 202 employs a spherical laser scanner and a laser sensor.

[0035] After the workpiece is conveyed onto the material conveyor 4, the robotic arm 201 with a spherical laser scanner and laser sensor scans the outer contour of the workpiece. The detection data is transmitted to an external terminal, where the system performs data analysis to obtain the dimensional point cloud model of the workpiece, which is used for process parameter matching and quality judgment.

[0036] like Figure 2 As shown, the adjustment mechanism includes an X-axis moving component 503 mounted on the upright 502; the X-axis moving component 503 is equipped with a Y-axis moving component 504, and the Y-axis moving component 504 is connected to the end plate 8.

[0037] The translation mechanism 5, the Y-axis moving component 504, and the X-axis moving component 503 all adopt linear modules.

[0038] The translation mechanism 5 is used to drive the adjustment mechanism and the brush roller 7 to translate. During the loading, unloading and inspection of the workpiece, the adjustment mechanism and the brush roller 7 are moved away from the base 1 and the brush roller 7 is moved away from the top of the loading roller 4, so as to avoid obstruction and hindrance to the loading, unloading and inspection of the workpiece.

[0039] During the grinding process, the translation mechanism 5 moves the adjustment mechanism and the brush roller 7 closer to the base 1, and the brush roller 7 moves above the workpiece. Subsequently, the X-axis moving component 503 and the Y-axis moving component 504 drive the brush roller 7 to move along the top of the workpiece according to the grinding trajectory generated by the detection data. At the same time, the drive mechanism 10 drives the brush roller 7 to rotate, thereby achieving the grinding of the workpiece surface.

[0040] like Figure 2 , Figure 4 as well as Figure 5 As shown, the drive mechanism 10 includes a protective cover 1001 fixedly mounted on the end plate 8. A motor 1002 is fixed on the outside of the protective cover 1001, and a first pulley 1003 and a second pulley 1004 are provided inside the protective cover 1001. A transmission belt 1005 is wound between the first pulley 1003 and the second pulley 1004. The output shaft of the motor 1002 is fixed to the first pulley 1003, and the second pulley 1004 is fixedly sleeved on the first end tube 704 of the brush roller 7.

[0041] The motor 1002 drives the first pulley 1003 to rotate, which in turn drives the second pulley 1004 to rotate via the transmission belt 1005. The second pulley 1004 then drives the brush roller 7 to rotate as a whole.

[0042] The brush bristles 702 on the brush roller 7 are made of steel wire. The brush roller 7 rotates and rubs on the surface of the workpiece to remove the surface oxide layer, rust and welding slag.

[0043] During the grinding process, some of the dust generated by the brush roller 7 will enter the bristles 702. In order to avoid affecting the subsequent grinding, an air supply pipe 11 is set and connected to an external air source, and a narrow groove 703 is set on the roller 701.

[0044] After the workpiece is polished, the brush roller 7 is moved away from the base 1 and moves closer to the first port 1101 at the end of the air supply pipe 11 until the first end pipe 704 is inserted into the first port 1101. The external air source inputs clean airflow into the air supply pipe 11. The clean airflow enters the first end pipe 704 through the air supply pipe 11 and then enters the roller 701. Finally, it is sprayed out from the narrow groove 703 on the circumference of the roller 701, blowing the dust in the bristles 702 outward, thus cleaning the inside of the bristles 702.

[0045] Furthermore, the brush roller 7 is provided with a dust collection part 9 at its top, the dust collection part 9 including a dust collection strip cover 901 with a bottom opening; the bottom opening of the dust collection strip cover 901 is attached to the top surface of the brush roller 7, the top of the dust collection strip cover 901 is fixedly connected to a top tube 902, and one end of the top tube 902 is fixedly connected to a second end tube 903, the second end tube 903 being fixed to the end plate 8; a dust collection pipe 12 is aligned with the second end tube 903, and a second port 1201 is provided at the end of the dust collection pipe 12. A rubber seal is provided inside the second port 1201.

[0046] After the workpiece is polished, as the brush roller 7 moves away from the base 1, the second end tube 903 moves closer to the second port 1201, and the two are inserted together. After insertion, the rubber seal is pressed to provide a seal for the connection between the two.

[0047] The end of the suction pipe 12 away from the second port 1201 is connected to an industrial vacuum cleaner. The industrial vacuum cleaner generates suction. After the second end pipe 903 is inserted into the second port 1201, the suction pipe 12 and the top pipe 902 cause the suction to act on the suction strip cover 901. The bottom opening of the suction strip cover 901 can be used for suction.

[0048] During the process of expelling dust from the inside of the bristles 702, the brush roller 7 is driven to rotate. The bristles 702 on each side of the brush roller 7 pass through the bottom opening of the dust suction hood 901 in sequence. The dust suction hood 901 sucks away the dust from the outside of the bristles 702. By blowing the dust from the inside of the bristles 702 outward and sucking the dust from the outside of the bristles 702, the cleaning effect of the bristles 702 is improved.

[0049] like Figures 6-8As shown, the blocking mechanism 13 includes a circular shaft 1301; a first disk 1302 is fixed to one end of the circular shaft 1301, and the first disk 1302 is fitted into the end of the roller 701 away from the first end tube 704; a second disk 1303 is fitted to the other end of the roller 701; the inner ring of the second disk 1303 is fixed to the circular shaft 1301 through a connecting block 1309; a plurality of blocking strips 1304 arranged in a ring array are fixed between the first disk 1302 and the second disk 1303; one end of the circular shaft 1301 extends into the first end tube 704, and the end of the circular shaft 1301 located in the first end tube 704 is connected to the power unit.

[0050] like Figures 7-11 As shown, the power unit includes a movable rod 1307 and a guide seat 1312 fixedly installed in the first end tube 704. The movable rod 1307 is slidably engaged with a square hole opened on the guide seat 1312. A connecting frame 1308 is fixed to one end of the movable rod 1307. A plug post 1306 is fixed to the connecting frame 1308. The plug post 1306 is slidably inserted into a groove 1305 opened on the cylindrical surface of the round shaft 1301. A fixing seat 1310 is also fixed in the first end tube 704. The fixing seat 1310 is elastically connected to the connecting frame 1308 through a first spring 1311. An end strip 1606 is provided in the end of the air supply pipe 11, and the end strip 1606 is aligned with the end of the movable rod 1307.

[0051] The mounting base 1310 is provided with a groove, and a part of the first spring 1311 is located in the groove, which provides storage space for the first spring 1311.

[0052] like Figures 6-9 As shown, when the first end tube 704 is not inserted into the first port 1101, the movable rod 1307 extends out from the first end tube 704, and the connecting bracket 1308 abuts against one side of the guide seat 1312 by the elastic force of the first spring 1311, wherein the shielding strip 1304 covers the inside of the narrow groove 703 to close the narrow groove 703.

[0053] When the first end tube 704 is inserted into the first port 1101, the movable rod 1307 moves closer to the end bar 1606 and is blocked by it, causing the movable rod 1307 to move into the first end tube 704. The movable rod 1307 drives the connecting frame 1308 and the insert 1306 to move together until the connecting frame 1308 abuts against the fixed seat 1310 and compresses the first spring 1311. The insert 1306 moves from one end of the inclined groove 1305 to the other end, causing the round shaft 1301, the first disc 1302, the second disc 1303 and the blocking bar 1304 to rotate together. The blocking bar 1304 leaves the narrow groove 703 (the blocking bar 1304 moves to the position between the narrow grooves 703), causing the narrow groove 703 to open.

[0054] When the first end tube 704 is moved away from the first port 1101, the elastic force of the first spring 1311 causes the connecting frame 1308, the movable rod 1307 and the insert 1306 to reset together. The connecting frame 1308 abuts against the guide seat 1312 again, and the insert 1306 slides in the inclined groove 1305, causing the round shaft 1301, the first disc 1302, the second disc 1303 and the blocking strip 1304 to reset and rotate together. The blocking strip 1304 covers and seals the narrow groove 703 again.

[0055] With the above design, when the first end tube 704 is inserted into the first port 1101, the narrow groove 703 is automatically opened to ensure that the narrow groove 703 can blow air into the bristles 702; when the first end tube 704 is separated from the first port 1101, the narrow groove 703 is automatically closed. During the process of the narrow groove 703 not blowing air outward, dust is prevented from entering the roller 701 through the narrow groove 703.

[0056] In practical implementation, the movable rod 1307 is equipped with a ball bearing at the end that contacts the end bar 1606 to reduce wear between the movable rod 1307 and the end bar 1606 when the brush roller 7 rotates.

[0057] like Figure 9 As shown, a disc 1313 is fixed on the movable rod 1307, and a sealing gasket 1314 is fixed on the disc 1313; an inner ring 7042 is fixed on the inner wall of the first end tube 704. When the first end tube 704 is not inserted into the first port 1101, the sealing gasket 1314 is attached to one side of the inner ring 7042. The diameter of the disc 1313 is smaller than the inner diameter of the first end tube 704, and the diameter of the disc 1313 is larger than the inner diameter of the inner ring 7042.

[0058] When the first end tube 704 is not connected to the first port 1101, such as Figure 9 As shown, the sealing gasket 1314 is attached to one side of the inner ring 7042 to seal the first end tube 704. When the first end tube 704 is inserted into the first port 1101, the movable rod 1307 moves into the first end tube 704. The movable rod 1307 drives the disc body 1313 and the sealing gasket 1314 to move together, and the sealing gasket 1314 separates from the inner ring 7042, so that the first end tube 704 automatically opens. When the first end tube 704 is subsequently separated from the first port 1101, the movable rod 1307 drives the disc body 1313 and the sealing gasket 1314 to reset together, and re-seal the first end tube 704. Through this design, the first end tube 704 is automatically sealed when it is not connected to the first port 1101, preventing dust from entering the first end tube 704.

[0059] like Figure 10As shown, a sealing ring 1102 is fixed inside the first port 1101, and an annular cavity 1103 is provided on the inner wall of the first port 1101. A plurality of oil drain holes 1104 are evenly distributed on the sealing ring 1102, and the oil drain holes 1104 communicate with the annular cavity 1103. An oil injection mechanism 16 is connected to the annular cavity 1103. An end plate 7041 is provided at the end of the first end tube 704. The end plate 7041 is used to insert into the first port 1101 and fit tightly against the sealing ring 1102.

[0060] After the first end tube 704 is connected to the first port 1101, the end plate 7041 presses the sealing ring 1102 to ensure the sealing of the connection; while during the cleaning process of the bristles 702, the brush roller 7 as a whole needs to rotate, so that the end plate 7041 rotates on the sealing ring 1102, and the sealing ring 1102 and the end plate 7041 rub against each other.

[0061] To reduce friction and wear, an oil injection mechanism 16 is provided to inject lubricating oil into the annular cavity 1103. The injected oil is distributed to various parts of the sealing ring 1102 through the oil drain hole 1104 to achieve lubrication and reduce rotational wear.

[0062] like Figure 8 , Figure 10 as well as Figure 11 As shown, the oil injection mechanism 16 includes a fixing frame 1601 fixed inside the air supply pipe 11. A cylinder 1602 is fixed to one side of the fixing frame 1601. An inner seat 1603 is fixed inside the cylinder 1602. The inner seat 1603 and the inner wall of the cylinder 1602 form an oil cavity, and a piston 1604 is fitted inside the oil cavity. A plunger 1605 is fixed to the piston 1604, and one end of the plunger 1605 is fixed to an end bar 1606. The end bar 1606 and the inner seat 1602 are fixed to each other. The three parts are elastically connected by a second spring 1607. One end of the cylinder 1602 is fixed with a first one-way valve 1608 and a second one-way valve 1610, and one end of the first one-way valve 1608 and one end of the second one-way valve 1610 are both connected to the oil chamber. The first one-way valve 1608 and the second one-way valve 1610 are respectively connected to an oil inlet pipe 1609 and an oil outlet pipe 1611. The oil inlet pipe 1609 is connected to an oil tank 15, and the oil outlet pipe 1611 is connected to the annular cavity 1103.

[0063] When the first end tube 704 is inserted into the first port 1101, after the movable rod 1307 and the end strip 1606 are in contact, the movable rod 1307 pushes the end strip 1606 to move, so that the end strip 1606 is in contact with the side wall of the fixed frame 1601, and then the end strip 1606 provides a block for the movable rod 1307; Figure 9In the state shown, the first spring 1311 is already in a compressed state, and at this time the elastic force of the first spring 1311 is greater than the elastic force of the second spring 1607 in a fully compressed state. Through this design, the process of moving the push end bar 1606 is achieved.

[0064] During the movement of the end bar 1606, the end bar 1606 drives the plunger 1605 and piston 1604 to move together. The piston 1604 pushes the oil in the oil chamber, so that the oil enters the annular cavity 1103 through the second check valve 1610 and the oil outlet pipe 1611, and compresses the second spring 1607.

[0065] The first end tube 704 is separated from the first port 1101, and the end bar 1606 loses the pushing force of the movable rod 1307. The piston 1604, the plunger 1605 and the end bar 1606 are reset by the elastic force of the second spring 1607. The oil chamber draws oil from the oil tank 15 through the first one-way valve 1608 and the oil inlet pipe 1609 to replenish the oil for the next lubrication.

[0066] The above design enables automatic oil injection and lubrication, eliminating the need for manual operation.

[0067] like Figures 3-4 As shown, it also includes a top mount 601, on which a side frame 6 is fixed. The suction pipe 12 and the air supply pipe 11 are fixedly installed on the side frame 6. One end of the suction pipe 12 with a second port 1201 and one end of the air supply pipe 11 with a first port 1101 are both fixed to the top mount 601. The side frame 6 and the top mount 601 provide mounting support for the suction pipe 12 and the air supply pipe 11. The oil tank 15 is also installed on the top mount 601, which provides a mounting position for the oil tank 15.

[0068] like Figure 6 , Figure 8 as well as Figure 12 As shown, an opening and closing mechanism 14 is installed on the top seat 601. The opening and closing mechanism 14 includes a housing 1401 fixed to the side wall of the top seat 601. A transmission part is provided inside the housing 1401, and the input end of the transmission part is connected to a push bar 1402, which is located outside the housing 1401. The output end of the transmission part is connected to a rotating shaft 1403, which is rotatably mounted inside the housing 1401. A return torsion spring 1408 is installed on the rotating shaft 1403, and the return torsion spring 1408 is connected to the inner wall of the housing 1401. A cover 1404 is fixed to one end of the rotating shaft 1403. An elastic telescopic member 801 is fixed on the end plate 8. The elastic telescopic member 801 is used to push the push bar 1402. The elastic telescopic member 801 is preferably a gas spring.

[0069] The transmission unit includes a cylindrical gear 1406 rotatably mounted in the housing 1401. The cylindrical gear 1406 and the rotating shaft 1403 are both coaxially fixed with a bevel gear 1407, and the two bevel gears 1407 mesh. The cylindrical gear 1406 meshes with a rack 1405, and the rack 1405 is slidably mounted in the housing 1401. The rack 1405 is fixed to the push bar 1402.

[0070] like Figure 6 and Figure 8 As shown, when the first end tube 704 is not connected to the first port 1101, the cover 1404 covers the outside of the first port 1101 to seal the first port 1101 and prevent dust and foreign objects from entering. In specific implementations, a rubber seal is provided on the cover 1404 to ensure airtightness.

[0071] During the insertion of the first end tube 704 into the first port 1101, after the end of the elastic telescopic member 801 is in contact with the pushed strip 1402, there is a gap between the end of the movable rod 1307 and the cover 1404, such as... Figure 6 As shown, the first end tube 704 continues to move, and the elastic telescopic member 801 pushes the push bar 1402, causing the push bar 1402 to drive the rack 1405 to move together until the end of the rack 1405 away from the push bar 1402 is attached to the inner wall of the housing 1401. The rack 1405 moves and meshes with the cylindrical gear 1406, causing the cylindrical gear 1406 and a bevel gear 1407 to rotate together. Through the meshing transmission of the two bevel gears 1407, the rotating shaft 1403 drives the cover 1404 to rotate 180°, and the first port 1 101 completes the opening, and at the same time, the reset torsion spring 1408 deforms. After the above operation, the movable rod 1307 approaches the first port 1101, but the movable rod 1307 still has a gap from the first port 1101 that is greater than the thickness of the cover 1404. Subsequently, the first end tube 704 continues to move, the rack 1405 is blocked by the side wall of the housing 1401, the elastic telescopic member 801 retracts, the cover 1404 remains open, and the elastic telescopic member 801 can retract without affecting the subsequent complete insertion of the first end tube 704 and the first port 1101.

[0072] During the separation of the first end tube 704 from the first port 1101, the elastic telescopic member 801 first extends and resets, and the opening and closing mechanism 14 keeps the cover 1404 in the open state. After the elastic telescopic member 801 extends and resets, the movable rod 1307 also leaves the first port 1101. The first end tube 704 continues to move, and the elastic telescopic member 801 separates from the push bar 1402. The opening and closing mechanism 14 resets through the elastic force of the reset torsion spring 1408. Specifically, the reset torsion spring 1408 drives the rotating shaft 1403 and the bevel gear 1407 thereon to rotate. Through the meshing transmission of the bevel gear 1407, the cylindrical gear 1406 rotates. The cylindrical gear 1406 meshes with the rack 1405, causing the rack 1405 and the push bar 1402 to reset. The rotating shaft 1403 resets and rotates, causing the cover 1404 to reset and rotate 180°, closing the first port 1101.

[0073] It should be noted that the elastic telescopic component 801 is a gas spring. When the elastic telescopic component 801 is in an uncompressed state and is not in contact with the push bar 1402, it has a certain air pressure. Through this air pressure, the elastic telescopic component 801 pushes the push bar 1402, and after the cover 1404 is rotated open, the elastic telescopic component 801 still remains in an uncompressed state.

[0074] With the above design, when the first end tube 704 is plugged into the first port 1101, the first port 1101 will be automatically opened, and when the first end tube 704 is separated from the first port 1101, the first port 1101 will be automatically closed, ensuring dust protection without the need for manual operation.
