[0025] The dust scraping unit 1 is directly in contact with the guide rail, and the flexible dust scraping part 12 is responsible for scraping the large-particle dirt on the surface of the guide rail. During the movement of the guide rail, the dust scraping unit 1 closely contacts with the guide rail, scraping off the dust, debris and other impurities attached to the surface of the guide rail. This preliminary removal of most large-particle dirt reduces the burden of subsequent dust removal, effectively reduces the amount of pollutants entering the subsequent negative pressure adsorption unit 3 and air knife unit 4, and lays the foundation for the entire dust removal process. By scraping off large particles in time, it can prevent these particles from rolling and rubbing on the surface of the guide rail, thereby protecting the surface of the guide rail, reducing wear and tear, and prolonging the service life of the guide rail. The scraping piece fixing piece 13 is installed on one side of the dust scraping unit 1, which is used to fix the dust scraping unit 1, to ensure that it always maintains stable contact with the guide rail during operation, and will not displace or fall off when subjected to external forces such as vibration of the guide rail movement, impact of dust, etc. At the same time, it also provides a mounting basis for the first sealing isolation unit 2, connecting the dust scraping unit 1 with the subsequent components. It ensures the stable operation of the dust scraping unit 1, improves the reliability and continuity of dust scraping, and enables the entire dust scraping unit 1 to be tightly and stably installed in the device, maintaining the relative positional relationship between the components, which helps to improve the structural stability of the entire dust removal device. The first contact sealing piece 21 of the first sealing isolation unit 2 cooperates with the first reverse surface 22 on the other end surface of the scraping piece fixing piece 13 through the first protruding piece 23 on one end surface, forming a tight sealing structure to prevent dust and impurities from entering the interior of the device from the connection between the dust scraping unit 1 and the first sealing isolation unit 2. At the same time, it also plays a certain sealing role for the negative pressure adsorption unit 3, ensuring that the negative pressure adsorption unit 3 maintains a good negative pressure environment during operation. It effectively prevents dust leakage, improves the sealing performance of the dust removal device, avoids external pollutants from entering the interior of the device to interfere with the dust removal work, ensures that the negative pressure adsorption unit 3 can efficiently adsorb dust, and improves the dust removal effect of the entire dust removal device. The first isolation piece 24 separates the first contact sealing piece 21 from the negative pressure adsorption unit 3, playing a role in isolation and support. On the one hand, it can prevent the first contact sealing piece 21 from directly contacting the negative pressure adsorption unit 3 and causing friction and damage; on the other hand, it provides a stable mounting plane for the negative pressure adsorption unit 3, ensuring the installation accuracy and stability of the negative pressure adsorption unit 3. It protects the components and prolongs their service life, while ensuring the relative positional accuracy between the components, which helps to maintain the normal operation of the entire device and ensures the smooth progress of the dust removal work. The negative pressure adsorption block 31 of the negative pressure adsorption unit 3 is internally provided with an adsorption cavity 33, which is connected with an external dust collection equipment such as a vacuum pump through an adsorption interface 34. Under the action of the dust collection equipment, the adsorption cavity 33 forms a negative pressure environment, thereby adsorbing the dust and impurities blown up by the air knife unit 4. The structural design of the adsorption cavity 33 enables it to effectively collect and store dust, ensuring that the dust will not scatter everywhere in the device. By utilizing the principle of negative pressure adsorption, dust is efficiently adsorbed, which is a key link in the dust removal process.It can quickly adsorb and collect the dust blown up by the air knife unit 4, avoid the dust re-attached to the guide rail surface, further improve the dust removal rate, ensure the cleanliness of the guide rail, and prolong the service life of the guide rail. The first negative pressure adsorption layer sealing piece 32 is arranged between the first isolation piece 24 and the negative pressure adsorption block 31 to seal the adsorption cavity 33 and prevent negative pressure leakage. It works together with the first contact type sealing piece 21, the second negative pressure adsorption layer sealing piece 42, etc. to ensure that the entire negative pressure adsorption unit 3 is in a good sealed state, maintain the negative pressure environment in the adsorption cavity 33, and cooperate with the airflow of the air knife unit to realize the cleaning of dust. It ensures the adsorption effect of the negative pressure adsorption unit 3 and improves the dust removal efficiency. The good sealing performance enables the negative pressure generated by the dust collection equipment to fully act on the adsorption cavity 33, enhances the adsorption capacity of dust, reduces the possibility of dust leakage, and thus improves the performance of the entire dust removal device. The air knife block 41 of the air knife unit 4 is internally provided with an air knife cavity 43, which is connected with an external air source through an air inlet interface 46 to introduce compressed air into the air knife cavity 43. The air knife block 41 also provides a mounting position for the air knife angle stabilizing block 44 to ensure the stability and accurate exhaust direction of the air knife opening 45. It provides storage and transmission space for the compressed air of the air knife unit 4 to ensure that the compressed air can be stably sprayed out of the air knife opening 45. The structure design and installation precision directly affect the working effect of the air knife, play a key role in removing residual dirt on the guide rail surface, and help to improve the dust removal efficiency. The air knife angle stabilizing block 44 and the air knife block 41 form the air knife opening 45 and stabilize the exhaust angle of the air knife opening 45. In this scheme, the exhaust direction of the air knife opening 45 forms a specific exhaust angle with the upper end surface of the guide rail, and the exhaust angle is determined according to the model or size of the guide rail, preferably 25.41°. The application will not be described here. The air knife angle stabilizing block 44 can ensure that this angle remains stable during operation, so that the sprayed airflow can accurately blow towards the guide rail surface to blow up the remaining dirt. It ensures that the airflow blown by the air knife has a stable direction and angle, improves the impact force and effect of the airflow on the dirt on the guide rail surface. The stable exhaust angle enables the air knife to more effectively blow up the remaining dirt and blow it towards the negative pressure adsorption unit 3, enhancing the dust removal effect. The compressed air is sprayed at high speed from the air knife opening 45 to form a high-speed airflow to blow up the remaining dirt on the guide rail surface after the large particles are removed by the dustproof scraper 11. The two ends of the air knife opening 45 are placed above the U-shaped sealing strip 7 to ensure that the blown airflow acts on the guide rail surface in a relatively closed space, avoiding the diffusion of the airflow to the surrounding environment, reducing energy loss and the impact on the surrounding environment. The high-speed airflow blows up the remaining dirt, so that these dirt can be effectively adsorbed by the negative pressure adsorption unit 3, further improving the dust removal rate. At the same time, the relatively closed airflow environment improves the utilization efficiency of the airflow, reduces energy waste, and enhances the overall performance of the dust removal device. The air inlet interface 46 connects the external air source with the air knife cavity 43 and is the channel for the compressed air to enter the air knife unit 4. It ensures that the compressed air can stably and smoothly enter the air knife cavity 43 to provide power for the operation of the air knife.The air knife unit 4 can obtain sufficient compressed air to maintain the normal operation of the air knife. Stable air inlet ensures that the air flow blown by the air knife has stable pressure and flow rate, thereby improving the working effect of the air knife and helping to improve the dust removal efficiency of the entire dust removal device. The sealing piece 47 is arranged between the air knife block 41 and the second sealing isolation unit 5 to seal the air knife cavity 43 and prevent compressed air leakage. It works together with other sealing components to ensure that the air knife unit 4 maintains a good sealing state during operation, thereby improving the working efficiency of the air knife. The sealing performance of the air knife unit 4 is guaranteed, the leakage of compressed air is reduced, and the utilization efficiency of the air flow is improved. Good sealing performance makes the air flow blown by the air knife have stable pressure and flow rate, enhances the air blowing effect of the air knife on the dirt on the surface of the guide rail, and improves the performance of the dust removal device. The second isolation piece 51 of the second sealing isolation unit 5 separates the air knife unit 4 from the sealing strip fixing unit 6, and plays a role in isolation and support. On the one hand, it can prevent the air knife unit 4 from directly contacting the sealing strip fixing unit 6 and causing friction and damage; on the other hand, it provides a stable mounting plane for the second contact type sealing piece 53, ensuring the installation accuracy and stability of the second contact type sealing piece 53. Protecting the components and prolonging their service life, while ensuring the relative position accuracy between the components, helps to maintain the normal operation of the entire device and ensures the smooth progress of the dust removal work. The second protruding piece 54 on one end face of the second contact type sealing piece 53 cooperates with the second reverse face 52 on the other end face of the second isolation piece 51 to form a tight sealing structure, preventing dust and impurities from entering the interior of the device from the connection between the air knife unit 4 and the second sealing isolation unit 5. At the same time, it also plays a certain sealing role for the entire device, ensuring that the air flow and dust inside the device do not leak to the external environment. Effectively prevent dust leakage, improve the sealing performance of the dust removal device, avoid external pollutants from entering the device interior to interfere with the dust removal work, prevent dust inside the device from leaking to the surrounding environment, reduce the pollution to the environment, and improve the environmental performance of the entire dust removal device. The sealing strip fixing unit 6 is used to fix the U-shaped sealing strip 7 and provides a mounting position and support for the U-shaped sealing strip 7. At the same time, it fixes the dust scraping piece unit 1, the first sealing isolation unit 2, the negative pressure suction unit 3, the air knife unit 4, the second sealing isolation unit 5, etc. by means of bolt connection, and is connected with the sliding block, so that the entire dust removal device can be stably installed on the sliding block and move with the sliding block on the guide rail. Ensure the stable installation of the U-shaped sealing strip 7 and maintain the structural integrity and stability of the entire dust removal device. By fixing all components together, the entire device forms a tight whole, which can work cooperatively during operation to improve dust removal efficiency. At the same time, stable installation ensures that the dust removal device does not shift or fall off during the movement of the sliding block, ensuring the reliability of the dust removal work.It works together with the first contact sealing piece 21, the first negative pressure adsorption layer sealing piece 32, the second negative pressure adsorption layer sealing piece 42, the second contact sealing piece 53, etc. to form a contact sealing space on the guide rail side wall, providing sealing conditions for the adsorption cavity 33. At the same time, it can also block dust from entering the device from the side of the guide rail, further improving the sealing performance of the device. Enhance the sealing performance of the dust removal device to ensure that the negative pressure adsorption unit 3 can work in a good sealing environment and improve the adsorption effect. By blocking dust from entering from the side, the influence of external pollutants on the dust removal device is reduced, and the working efficiency and stability of the entire dust removal device are improved.

[0026] Working process

[0027] Preliminary dust scraping stage: First, the dust scraping piece 11 in the dust scraping piece unit 1 contacts the guide rail surface, and the flexible dust scraping part 12 uses its elasticity and close fit with the guide rail to scrape off most of the large particle dirt on the guide rail surface. After these large particle dirt is scraped off, it falls directly from the bottom of the device or is collected in a specific collection area.

[0028] Air knife dust blowing stage: After preliminary dust scraping by the dust scraping piece 11, the guide rail continues to move into the range of the air knife unit 4. The external air source supplies compressed air to the air knife cavity 43 in the air knife block 41 through the air inlet interface 46. The compressed air accumulates in the air knife cavity 43 and reaches a certain pressure, and then is sprayed out at high speed from the air knife port 45. Due to the action of the air knife angle stabilizing block 44, the air knife port 45 forms a specific exhaust angle with the upper surface of the guide rail, and the high-speed airflow accurately blows towards the guide rail surface, blowing up the remaining dirt.

[0029] Negative pressure adsorption stage: The dirt blown up by the air knife moves towards the negative pressure adsorption unit 3 under the action of the airflow. The negative pressure adsorption block 31 in the negative pressure adsorption unit 3 is connected to the external dust collection equipment through the adsorption interface 34, and under the action of the dust collection equipment, the adsorption cavity 33 forms a negative pressure environment. The dirt blown up is sucked into the adsorption cavity 33 under the action of negative pressure and is collected and stored in the adsorption cavity 33. In this process, the first negative pressure adsorption layer sealing piece 32, the second negative pressure adsorption layer sealing piece 42 and other sealing components work together to ensure the sealing performance of the adsorption cavity 33, maintain a good negative pressure environment and improve the adsorption effect.

[0030] Continuous cycle stage: With the continuous movement of the sliding block, the dust removal device repeatedly performs the above process to continuously remove dust from the guide rail surface, ensuring that the guide rail remains clean, reducing the impact of dust on the precision and service life of the guide rail, and ensuring the normal operation of the ball linear guide rail.

[0031] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the specific details of the above-described embodiments, and various equivalent transformations of the technical solutions of the present application can be made within the technical concept of the present application, and these equivalent transformations all belong to the protection scope of the present application.
