Description

A polishing and rust removal machine for steel processing

Technical Field

The present application relates to the technical field of steel processing equipment, and in particular to a polishing and rust removal machine for steel processing.

Background Art

With the development of society and the improvement of living standards, people's demand for resources has also increased, and the problem of resource waste has become more and more obvious. Among them, steel is an indispensable resource in people's daily life and construction. Its surface needs to be polished during processing. In addition, the surface of steel is prone to rust after a period of use. Directly discarding rusted steel will result in a serious waste of resources. In order to save resources and promote their sustainable use, rusted steel is usually polished and rust-removed to facilitate its reuse.

Existing equipment for polishing and derusting the surface of steel usually includes a moving device for controlling the movement of the steel and a polishing device for derusting the surface of the steel. The polishing device includes a polishing piece driven to rotate by a motor. The rotating polishing piece contacts the surface of the steel. At the same time, the moving device drives the steel to be derusted to move, so that the surface of the steel in contact with the polishing piece can be polished and derusted.

When polishing and rust removal equipment is used to polish and rust remove the surface of steel, the rust layer on the surface of the steel will be peeled off after polishing and rust removal, and a large number of metal particles will be separated. The metal particles are likely to fall back onto the surface of the steel after polishing and rust removal, affecting the effect of polishing and rust removal of the steel; at the same time, a large number of metal particles will form dust around the working environment, and the metal particles formed by the rust layer are more harmful to the human body, not only polluting the surrounding environment, but also affecting the health of the workers in the working environment.

Therefore, there is an urgent need for a polishing and rust removal equipment that can reduce the dust hazard while ensuring the polishing and rust removal effect of steel.

The first polishing piece is located above the movable track. The first impeller is arranged at both ends of the axis direction of the first polishing piece. The second driving piece drives the first polishing piece to rotate; the second polishing assembly includes a second polishing piece, a second impeller and a third driving piece. The second polishing piece is rotatably connected to the dust removal room. The rotation axis of the second polishing piece is vertical. Several second polishing pieces are respectively located on both sides of the movable track. The second impeller is arranged at the end of the second polishing piece away from the movable track. The third driving piece drives the second polishing piece to rotate.

By adopting the above technical solution, after the steel is fixed on the movable seat, the first driving member drives the movable seat along the movable track to pass through the dust reduction room. In the process of the steel passing through the dust reduction room, several first polishing assemblies and several second polishing assemblies will polish and remove rust on multiple surfaces of the steel, with high polishing and rust removal efficiency; after a large number of metal particles are formed on the surface of the steel after polishing and rust removal, the second impeller rotates with the second polishing member to form an airflow to blow off the metal particles that fall on the top surface of the steel, and the first impeller rotates with the first polishing member to form an airflow to blow off the metal particles that fall on the side surface of the steel, and at the same time drives the metal particles raised in the dust reduction channel to move toward the bottom, thereby reducing the influence of metal particles adhering to the steel surface on the polishing and rust removal effect of the steel, and reducing the degree of dust, thereby improving the polishing and rust removal effect of the steel and reducing the harm of metal particle dust.

Optionally, a dust collecting trough is provided below the dust reduction room, the dust collecting trough is communicated with the dust reduction channel, and the dust collecting trough is located below the movable seat entering the dust reduction channel.

The metal particles in the dust collecting trough will be located below the movable seat and the steel fixed on the movable seat. At this time, the movable seat and the steel will act as a windbreak for the metal particles in the dust collecting trough, reducing the disturbing effect of the airflow in the dust removal channel on the metal particles in the dust collecting trough, so that the metal particles can stay stably in the dust collecting trough after entering the dust collecting trough, thereby further reducing dust.

Optionally, there are two guide grooves below the dust reduction room, and the two guide grooves are respectively located on both sides of the dust collecting groove. The guide grooves are simultaneously connected to the dust reduction channel and the dust collecting groove, and the two guide grooves are respectively located below several of the second polishing components.

By adopting the above technical solution, in the dust removal channel, a large number of metal particles formed by polishing and rust removal of steel will fall from both sides of the steel into the guide groove, and then enter the dust collecting trough from the guide groove for collection; the airflow formed by the rotation of the first impeller will guide the metal particles raised in the dust removal channel to move toward the guide groove, helping the metal particles to be collected in the dust collecting trough. At the same time, the airflow formed by the first impeller can make the metal particles gather in the middle position of the dust collecting trough under the guidance of the guide groove, which is convenient for the staff to clean the metal particles in the dust collecting trough later.

Optionally, it also includes a plurality of dust covers, which are arranged in the guide groove, and the plurality of dust covers correspond one-to-one to the plurality of second polishing assemblies; the second polishing assembly also includes a third impeller, which is connected to one end of the second polishing member close to the movable track; the interior of the dust cover has a cavity, and the third impeller is located in the cavity; the dust cover is provided with a plurality of dust holes, and the dust cover is provided with filters at the plurality of dust holes, the dust holes are communicated with the cavity, and the rotation of the third impeller drives air into the cavity through the dust holes.

By adopting the above technical solution, the third impeller rotates with the second polishing piece to form an airflow. The airflow formed by the third impeller will drive the metal particles around the dust hood to gather in the direction close to the dust hood, so that the intensity of the airflow passing through the guide groove is increased, thereby reducing the probability of metal particles staying in the guide groove; at the same time, it can make the metal particles located in the dust collecting trough more concentrated in the accumulation position in the dust collecting trough, further facilitating the staff to clean the metal particles in the dust collecting trough later.

Optionally, the moving device further includes a dust sweeping member, which is disposed on the movable seat and is located in the dust collecting trough.

By adopting the above technical solution, when the movable seat slides along the movable track, the dust sweeping piece moves in the dust collecting trough, so that the dust sweeping piece can sweep the metal particles collected in the dust collecting trough to the corner of the dust collecting trough, further facilitating the staff to clean the metal particles in the dust collecting trough later.

Optionally, the dust-sweeping piece has a dust-shoveling portion at one end away from the movable seat, and has a movable portion at one end of the dust-sweeping piece close to the movable seat, and the interior of the movable seat has a movable space for the movable portion to move; when the movable seat slides until the dust-shoveling portion abuts against the wall of the dust collecting trough, the movable seat continues to slide to drive the dust-sweeping piece to move toward the movable seat.

By adopting the above technical solution, when the dust sweeping piece moves along with the movable seat, the dust shoveling part can scoop up the metal particles along the way in the dust collecting trough and carry them with it; afterward, the dust sweeping piece moves upward under the limit of the dust collecting trough wall, and the dust shoveling part can drive the metal particles it carries to move upward together, so that the metal particles leave the dust collecting trough, thereby further facilitating the staff to clear the metal particles from the dust collecting trough.

Optionally, the dust-sweeping piece has a guide portion on the movable portion, and the movable seat is provided with a guide groove adapted to the guide portion on the inner wall of the movable space; the guide groove includes a movable groove and a rotating groove that are interconnected, and the rotating groove is located above the movable groove. When the dust-sweeping piece moves toward the movable seat, the guide portion moves along the movable groove; when the guide portion is located in the rotating groove, the movable seat continues to slide to drive the dust-sweeping piece to rotate relative to the movable seat.

By adopting the above technical solution, the guide groove guides the movement of the dust sweeping piece relative to the movable seat. When the dust collecting groove wall limits the dust sweeping piece, the guide part will drive the dust sweeping piece to move upward under the guidance of the movable groove to lift the metal particles carried by it; when the metal particles carried by the dust sweeping piece are lifted up and leave the dust collecting groove, the guide part will drive the dust sweeping piece to rotate under the guidance of the rotating groove to pour out the metal particles carried by the dust sweeping piece, making it convenient for the staff to clean the metal particles outside the dust reduction room.

Optionally, the movable device also includes a plurality of elastic members, and the plurality of elastic members are arranged in the movable space. The two ends of the elastic members are respectively connected to the movable seat and the dust-sweeping member, and the elastic members drive the dust-sweeping member to move in a direction away from the movable seat, so that the dust-shoveling part and the bottom groove wall of the dust collecting groove are kept in contact with each other.

By adopting the above technical solution, when the dust sweeping piece moves in the dust collecting trough, a number of elastic parts will drive the dust shoveling part to maintain contact with the trough wall at the bottom of the dust collecting trough, thereby improving the effect of the dust shoveling part in scooping up metal particles; after the dust sweeping piece moves relative to the movable seat under the limitation of the trough wall of the dust collecting trough, the limitation of the dust sweeping piece by the trough wall of the dust collecting trough is released, and a number of elastic parts can drive the dust sweeping piece to move and reset, so that the dust sweeping piece can stably perform the dust sweeping function.

Optionally, both ends of the dust collection room are provided with dust collection troughs, and the two dust collection troughs are respectively located on both sides of the dust collecting trough. After the dust sweeping piece moves toward the movable seat, the dust sweeping piece transfers the metal particles in the dust collecting trough to the dust collection trough.

By adopting the above technical solution, after the dust sweeping piece takes the metal particles it carries away from the dust collecting trough and pours them out, the metal particles will leave the dust reduction channel and be transferred to the dust storage trough, thereby reducing the impact of the airflow in the dust reduction channel on the poured-out metal particles, and at the same time can further facilitate the staff to clean the metal particles outside the dust reduction room.

Optionally, a plurality of the first polishing assemblies and a plurality of the second polishing assemblies are alternately distributed in the dust reduction channel along the sliding direction of the movable seat.

By adopting the above technical solution, after the first polishing component polishes and removes rust on the surface of the top of the steel material, the metal particles remaining on the top surface of the steel material can be blown off by the airflow formed by the subsequent rotation of several second impellers; at the same time, after the second polishing component polishes and removes rust on the surface of the side of the steel material, the metal particles remaining on the side surface of the steel material can also be blown off by the airflow formed by the subsequent rotation of several first impellers, thereby further reducing the probability of metal particles staying on the surface of the steel material after polishing and rust removal, and further improving the effect of polishing and rust removal of the steel.

DETAILED DESCRIPTION

The present application is further described in detail below with reference to Figures 1-9.

With reference to Figures 1 and 2, an embodiment of the present application discloses a polishing and derusting machine for steel processing, which is used to polish and derust the surface of a regularly shaped steel material 1 (a surface consisting of multiple connected planes). In this embodiment, the steel material 1 to be polished and derusted is preferably a square tube 1. In other embodiments, the steel material 1 to be polished and derusted may also have other shapes, and the corresponding polishing and derusting machine can be adaptively adjusted according to the shape of the steel material 1.

The polishing and rust removal machine includes a moving device 2, a polishing device 3, and a dust reduction chamber 4. The moving device 2 is used to move the steel material 1 through the dust reduction chamber 4, and the polishing device 3 is installed in the dust reduction chamber 4. As the steel material 1 passes through the dust reduction chamber 4, the polishing device 3 polishes and removes rust from the surface of the steel material 1. At the same time, the dust reduction chamber 4 is used to reduce the impact of the spread of metal dust particles on the surrounding environment. This ensures the efficiency and effectiveness of polishing and rust removal of the steel material 1 while reducing the harm caused by metal dust particles.

The dust-reduction room 4 is a rectangular parallelepiped structure fixedly mounted on the ground. A dust-reduction channel 41 is provided along the length of the dust-reduction room 4 for the steel 1 to pass through. In this embodiment, the shape of the dust-reduction channel 41 is preferably adapted to the shape of the steel 1, i.e., it is also a rectangular parallelepiped structure.

The moving device 2 includes a moving track 21, a movable base 22, and a first drive member 23. The moving track 21 is fixedly mounted on the ground and comprises two parallel linear rails, the length of which is parallel to the length of the dust reduction chamber 4. The moving track 21 passes through the dust reduction chamber 4 and is located at the bottom of the dust reduction channel 41.

The movable seat 22 is located above the movable rail 21 and is slidably connected to the movable rail 21. The sliding direction of the movable seat 22 is parallel to the length direction of the movable rail 21. The first driving member 23 is fixedly mounted on the movable seat 22, and the first driving member 23 drives the movable seat 22 to slide along the movable rail 21. In this embodiment, the first driving member 23 is preferably a stepping motor, and the movable rail 21 is preferably provided with a rack structure along its length. The output end of the first driving member 23 has a gear structure, and the gear structure on the first driving member 23 meshes with the rack structure on the movable rail 21. That is, after the first driving member 23 is activated, the movable seat 22 is driven to slide along the movable rail 21 through the cooperation of the gear structure and the rack structure.

The movable seat 22 has a fixing device 5 for fixing the steel 1. In this embodiment, the fixing device 5 preferably includes a plurality of fixing components 51, and the plurality of fixing components 51 are respectively installed at both ends of the sliding direction of the movable seat 22 itself, and the fixing device 5 preferably includes two fixing components 51 in total.

The fixing assembly 51 includes a fourth driving member 511 and a clamping member 512. The clamping member 512 is rotatably connected to the movable seat 22. The rotation axis of the clamping member 512 is horizontal and perpendicular to the sliding direction of the movable seat 22. The fourth driving member 511 is fixedly installed on the movable seat 22. Preferably, the fourth driving member 511 is a servo motor, and the fourth driving member 511 drives the clamping member 512 to rotate.

During the process of fixing the steel 1 on the movable seat 22, the steel 1 is hoisted and placed on the movable seat 22 in a state where its length direction is parallel to the length direction of the movable seat 22 and is located between the two fixing components 51. Then, the two fourth driving members 511 are controlled to drive the two clamping members 512 to rotate into the interior of the steel 1 and clamp the inner wall of the bottom of the steel 1, thereby fixing the position of the steel 1 on the movable seat 22.

In other embodiments, the steel 1 may be fixed on the movable seat 22 by clamping on both sides, that is, a plurality of fixing components 51 are respectively located on both sides of the movable seat 22, and the fixing components 51 apply force in opposite directions to the steel 1 to fix the position of the steel 1 on the movable seat 22.

1 and 3 , the polishing device 3 includes a plurality of first polishing assemblies 31 and a plurality of second polishing assemblies 32, both of which are located in the dust reduction channel 41. The first polishing assemblies 31 are used to polish and remove rust from the top surface of the steel material 1, while the second polishing assemblies 32 are used to polish and remove rust from the side surfaces of the steel material 1.

The first polishing assembly 31 includes a first polishing member 311 and a second driving member 312. The first polishing member 311 is an overall cylindrical structure and is rotatably connected to the dust chamber 4. The rotation axis of the first polishing member 311 coincides with its own axis and is horizontal and perpendicular to the length of the dust chamber 4. The second driving member 312 is fixedly mounted on the dust chamber 4 and is located above the dust chamber 4. The second driving member 312 is preferably a stepping motor and drives the first polishing member 311 to rotate.

As the movable seat 22 slides and drives the steel material 1 through the dust reduction passage 41, the top surface of the steel material 1 abuts against the bottom of the first polishing member 311. Simultaneously, the second driving member 312 drives the first polishing member 311 to continue rotating. Furthermore, during the rotation of the first polishing member 311, the force exerted by the bottom of the first polishing member 311 on the top surface of the steel material 1 is in the opposite direction of the movement of the steel material 1.

In this embodiment, the axial dimension of the first polishing member 311 is preferably equal to the width of the steel material 1 (in other embodiments, the axial dimension of the first polishing member 311 may also be greater than the width of the steel material 1). When the first polishing member 311 contacts the top surface of the steel material 1, the entire bottom of the first polishing member 311 contacts the top surface of the steel material 1. In this case, the first polishing member 311 polishes and removes rust from the entire top surface of the steel material 1 while the steel material 1 passes through the dust reduction passage 41.

The second polishing assembly 32 includes a second polishing member 321 and a third driving member 322. The second polishing member 321 is a cylindrical structure and is rotatably connected to the dust removal chamber 4. The rotation axis of the second polishing member 321 coincides with the axis of the second polishing member 321 itself and is vertical. The second polishing member 321 is located to the side of the dust removal passage 41. The third driving member 322 is fixedly mounted on the dust removal chamber 4 and is located to one side of the dust removal chamber 4. The third driving member 322 is preferably a stepping motor and drives the second polishing member 321 to rotate.

As the movable seat 22 slides and drives the steel material 1 through the dust suppression passage 41, the second polishing member 321 is positioned on one side of the steel material 1, with the side surface of the steel material 1 contacting the second polishing member 321. Simultaneously, the third driving member 322 drives the second polishing member 321 to continue rotating. During the rotation of the second polishing member 321, the force exerted by the second polishing member 321 on the side surface of the steel material 1 is in the opposite direction of the movement of the steel material 1.

In this embodiment, the axial dimension of the second polishing member 321 is preferably equal to the height dimension of the steel material 1 (in other embodiments, the axial dimension of the second polishing member 321 may also be greater than the height dimension of the steel material 1). Furthermore, when the second polishing member 321 contacts the side surface of the steel material 1, the entire second polishing member 321 preferably contacts the side surface of the steel material 1. In this case, the second polishing member 321 polishes and removes rust from the entire side surface of the steel material 1 while the steel material 1 passes through the dust reduction passage 41.

Furthermore, it is preferred that the plurality of second polishing assemblies 32 be symmetrically distributed on both sides of the dust reduction passage 41, and that the plurality of second polishing assemblies 32 located on the same side of the dust reduction passage 41 be evenly spaced along the length of the dust reduction room 4. Furthermore, it is preferred that the plurality of second polishing assemblies 32 be evenly spaced along the length of the dust reduction room 4 at the top of the dust reduction passage 41. This allows the polishing device 3 to simultaneously polish and derust the top surface and both sides of the steel material 1, and multiple polishing and derusting processes can improve the efficiency and effectiveness of the polishing and derusting process on the steel material 1.

3 and 4 , the first polishing assembly 31 also includes two first impellers 313 , which are fixedly mounted on opposite ends of the first polishing member 311 along its axis, with the axes of the first impellers 313 coinciding with the rotational axis of the first polishing member 311. As the steel material 1 moves through the dust removal passage 41 , the two first impellers 313 are positioned on either side of the steel material 1. Furthermore, as the first impellers 313 rotate with the first polishing member 311, airflow is generated at the edges of the dust removal passage 41 , dislodging metal particles remaining on the side surfaces of the steel material 1 and causing them to fall to the bottom of the dust removal passage 41 .

The second polishing assembly 32 also includes a second impeller 323, which is fixedly mounted on top of the second polishing member 321, with its axis coinciding with the rotational axis of the second polishing member 321. As the steel material 1 moves through the dust removal passage 41, the second impeller 323 is positioned above the steel material 1. Furthermore, as the second impeller 323 rotates with the second polishing member 321, it creates an airflow at the top of the dust removal passage 41. This airflow dislodges metal particles remaining on the top surface of the steel material 1, allowing the metal particles to fall from both sides of the steel material 1 to the bottom of the dust removal passage 41.

In order to ensure that the airflow generated by the rotation of the first impeller 313 can stably blow off the metal particles remaining on the side surface of the steel 1, and the airflow generated by the rotation of the second impeller 323 can also stably blow off the metal particles remaining on the top surface of the steel 1, in other embodiments, guide vanes can be installed on the circumference of the first impeller 313 and the second impeller 323 to make the airflow generated by the rotation of the first impeller 313 move downward, and the airflow generated by the rotation of the second impeller 323 is directed toward the second impeller 323 on the other side, thereby ensuring that the airflow can stably drive the metal particles remaining on the surface of the steel 1 to fall to the bottom of the dust reduction channel 41.

Furthermore, it is preferred that several first polishing assemblies 31 and several second polishing assemblies 32 are distributed at intervals in the dust reduction channel 41 along the direction in which the steel 1 moves, that is, several first polishing assemblies 31 and several second polishing assemblies 32 are alternately distributed in sequence, so that after the metal particles formed after the first polishing assembly 31 polishes and rusts the top surface of the steel 1 and stay on the surface of the top of the steel 1, the several second impellers 323 can blow off the metal particles on the top surface of the steel 1 in time; and after the metal particles formed after the second polishing assembly 32 polishes and rusts the side surface of the steel 1 and stay on the surface of the side of the steel 1, the several first impellers 313 can blow off the metal particles on the side surface of the steel 1 in time. In this embodiment, for ease of display, the polishing device 3 includes a first polishing component 31 and two second polishing components 32. When the steel 1 passes through the dust reduction channel 41, the first polishing component 31 first polishes and removes rust on the steel 1, and the two second polishing components 32 then polish and remove rust on the steel 1; in other embodiments, the polishing device 3 may include a larger number of first polishing components 31 and second polishing components 32.

Furthermore, a dust collecting trough 7 for collecting metal particles is provided on the ground below the dust reduction room 4. The dust collecting trough 7 is located below the movable track 21, and the dust collecting trough 7 is communicated with the dust reduction channel 41. When the movable seat 22 slides to drive the steel material 1 through the dust reduction channel 41, the movable seat 22 and the steel material 1 can cover the portion of the dust collecting trough 7 that has passed through. After the metal particles fall to the bottom of the dust reduction channel 41, the airflow formed by the first impeller 313 can drive the metal particles at the bottom of the dust reduction channel 41 into the dust collecting trough 7, and the movable seat 22 and the steel material 1 above the dust collecting trough 7 can act as a windbreak for the metal particles in the dust collecting trough 7, thereby reducing the impact of the airflow on the metal particles and allowing the metal particles to maintain a stable position in the dust collecting trough 7.

Furthermore, two guide grooves 8 are opened on the ground to guide the movement of metal particles. The two guide grooves 8 are respectively located on both sides of the dust collecting trough 7. The guide grooves 8 are connected to the dust reduction channel 41 and the dust collecting trough 7 at the same time, and the two guide grooves 8 are respectively located below the two second polishing components 32.

In this embodiment, the groove wall of the guide groove 8 is preferably an inclined surface inclined downward in the direction close to the dust collecting groove 7. After the metal particles fall into the guide groove 8, they will move along the inclined groove wall into the dust collecting groove 7; at the same time, the dust collecting groove 7 also has a guiding effect on the airflow. The airflow generated by the rotation of the first impeller 313 enters the dust collecting groove 7 under the guidance of the guide groove 8, which can not only help the metal particles enter the dust collecting groove 7 and reduce the probability of the metal particles staying at the bottom of the dust reduction channel 41 or on the groove wall of the guide groove 8, but also enable the metal particles in the dust collecting groove 7 to gather and accumulate toward the middle position.

3 and 5 , further, the polishing and rust removal machine further includes a plurality of dust hoods 6, and the second polishing assembly 32 further includes a third impeller 324. Preferably, the dust hood 6 is a cylindrical cover structure as a whole, and the plurality of dust hoods 6 correspond one-to-one to the plurality of second polishing assemblies 32. The dust hood 6 is fixedly installed at the bottom of the dust reduction room 4 and is located in the guide groove 8, and the axis of the dust hood 6 coincides with the axis of the second polishing member 321. The interior of the dust hood 6 has a cavity 61, and the circumference of the dust hood 6 is provided with a plurality of dust holes 62, the two ends of the dust holes 62 are respectively communicated with the guide groove 8 and the cavity 61, and the plurality of dust holes 62 are distributed in a circular array on the circumference of the dust hood 6 with the axis of the dust hood 6 as the axis, and the dust hood 6 is covered with a filter 63 for filtering metal particles at each dust hole 62.

The third impeller 324 is fixedly connected to the second polishing member 321. The third impeller 324 is located on a side of the second polishing member 321 away from the second impeller 323, and the axis of the third impeller 324 coincides with the axis of the second polishing member 321. The third impeller 324 is located in the cavity 61. A plurality of air holes 10 are formed on the ground, corresponding one-to-one with the dust hoods 6. One end of the air hole 10 communicates with the bottom of the cavity 61, and the other end of the air hole 10 extends through the ground and communicates with the space outside the dust collection chamber 4. In this embodiment, the third impeller 324 is preferably located below the plurality of dust collecting holes 62. When the third impeller 324 rotates along with the second polishing member 321, the third impeller 324 will form an airflow downward along its own axis. At this time, the airflow will drive the air in the guide groove 8 and the air in the dust collecting groove 7 to move toward the dust hood 6. After the air passes through the dust collecting holes 62 and enters the cavity 61, it will be discharged to the outside of the dust reduction chamber 4 through the air holes 10. The airflow generated by the rotation of the third impeller 324 can further guide the metal particles entering the guide groove 8 to move into the dust collecting groove 7, and at the same time, can cause the metal particles in the dust collecting groove 7 to move and concentrate toward the dust hood 6, so that the metal particles are further accumulated in the dust collecting groove 7.

4 and 6 , the mobile device 2 further includes a dust sweeping member 24, which is mounted on the bottom of the movable seat 22 and is located in the dust collecting trough 7. During the process in which the first driving member 23 drives the movable seat 22 to slide in and out of the dust reduction channel 41, the dust sweeping member 24 remains located in the dust collecting trough 7; the end of the dust sweeping member 24 away from the movable seat 22 abuts against the trough wall at the bottom of the dust collecting trough 7. During the process in which the dust sweeping member 24 moves along with the sliding of the movable seat 22, the dust sweeping member 24 can sweep the metal particles in the dust collecting trough 7 to the corners at both ends of the dust collecting trough 7 in the longitudinal direction, making it easier for the staff to clean them later. At the same time, the metal particles can be further concentrated and accumulated, reducing the probability of dust generation.

Furthermore, the dust-sweeping member 24 has a dust-scooping portion 241 at one end away from the movable seat 22. The dust-scooping portion 241 preferably forms a T-shaped structure with the main body of the dust-sweeping member 24, i.e., the two ends of the dust-scooping portion 241 extend outward toward either side of the dust-sweeping member 24. When the dust-sweeping member 24 is located in the dust collecting trough 7, the end faces of the dust-scooping portion 241 abut against the bottom wall of the dust collecting trough 7. As the dust-sweeping member 24 slides with the movable seat 22 and moves within the dust collecting trough 7, the two ends of the dust-scooping portion 241 can scoop up metal particles in different movement directions, allowing the dust-sweeping member 24 to move along with the metal particles. In this embodiment, both ends of the dust-generating portion preferably have inclined surfaces that facilitate scooping up metal particles.

6 and 7 , the dust sweeping member 24 further includes a movable portion 242 at one end away from the dust scooping portion 241. Correspondingly, the movable seat 22 includes a movable space 221 within which the movable portion 242 can move. Preferably, the movable portion 242 and the main body of the dust sweeping member 24 also form a T-shaped structure, i.e., the ends of the movable portion 242 also extend outward toward the sides of the dust sweeping member 24. When the dust cleaning piece 24 is located in the dust collecting trough 7, the bottom end surfaces at both ends of the movable part 242 fit against the inner wall of the movable space 221, and the bottom end surfaces at both ends of the movable part 242 are both inclined surfaces inclined downward in the direction close to the main body of the dust cleaning piece 24, and the interior of the movable space 221 that is against it guides it; when the dust cleaning piece 24 slides with the movable seat 22 to the point where one end of the dust shoveling part 241 is against the groove wall at one end of the dust collecting trough 7, the movable seat 22 continues to slide and will drive the dust cleaning piece 24 to move upward relative to the movable seat 22 under the cooperation of the movable part 242 and the inner wall of the movable space 221, so that the dust cleaning piece 24 can move upward with the metal particles and take the metal particles away from the dust collecting trough 7.

In this embodiment, the movable seat 22 preferably has a limited sliding process along the movable rail 21, and the dust sweeping member 24 is preferably installed at one end in the longitudinal direction of the movable seat 22. During the sliding process of the movable seat 22 along the movable rail 21, the dust sweeping member 24 is always located within the range of the dust collecting trough 7, and the movable device 2 preferably delivers the steel material 1 to be polished and rust-removed into the dust removal chamber 4 and then delivers the polished and rust-removed steel material 1 back along the same route.

Referring to Figures 8 and 9 , further, the dust sweeping member 24 has guide portions 243 on both sides along the width direction of the movable seat 22, and the movable seat 22 has guide grooves 222 on the inner wall corresponding to the movable space 221, which are adapted to the guide portions 243. The guide portions 243 cooperate with the guide grooves 222, and the guide grooves 222 are used to guide the movement of the guide portions 243, thereby guiding the movement of the dust sweeping member 24 relative to the movable seat 22. In this embodiment, preferably, two guide grooves 222 are provided on the same inner wall of the movable space 221, and the two guide grooves 222 are symmetrically distributed, respectively used to guide the guide portions 243 during the sliding process of the movable seat 22 in different directions.

The overall trajectory of the guide groove 222 is inclined, and the inclination direction of the guide groove 222 is the same as the inclination direction of the bottom end surface of the corresponding end of the movable portion 242. The guide groove 222 includes a movable groove 223 and a rotating groove 224. Preferably, the movable groove 223 is a strip-shaped groove and the rotating groove 224 is a circular groove, and the movable groove 223 is located below the rotating groove 224. The two ends of the movable groove 223 in the longitudinal direction are respectively connected to the rotating groove 224 and the end of the movable groove 223 of the other guide groove 222. When the dust shoveling part 241 is in contact with the groove wall at the bottom of the dust collecting groove 7, the guide part 243 is located at the intersection of the two movable grooves 223. When the dust cleaning member 24 is in contact with the different groove walls at both ends of the dust collecting groove 7, and the movable seat 22 continues to slide, the guide part 243 will move along different movable grooves 223 to guide the dust cleaning member 24 to move upward relative to the movable seat 22. In this embodiment, the cross section of the guide portion 243 is preferably a square with rounded corners, and the guide portion 243 is adapted to the movable groove 223 .

When the guide portion 243 moves along the movable groove 223 to enter the rotating groove 224, the guide portion 243 can rotate in the rotating groove 224 with its own axis as the rotation axis; at this time, one end of the dust shoveling portion 241 is against the top of the groove wall at one end of the dust collecting groove 7, and the metal particles carried by the dust shoveling portion 241 have left the dust collecting groove 7; at this time, the movable seat 22 continues to slide, and the dust cleaning member 24 will rotate with the axis of the guide portion 243 as the rotation axis under the restriction of the groove wall of the dust collecting groove 7, so that the metal particles carried on the dust shoveling portion 241 can be poured out to one side of the dust collecting groove 7 and leave the dust reduction channel 41.

Furthermore, the mobile device 2 also includes a plurality of elastic members 25 and abutment members 26. The abutment members 26 are generally plate-shaped structures. The abutment members 26 are located in the movable space 221, and the abutment members 26 are in contact with and abut against the end face of the top of the movable part 242; a plurality of elastic members 25 are also located in the movable space 221 and above the abutment members 26. The two ends of the elastic member 25 are respectively fixedly connected to the movable seat 22 and the abutment members 26. Preferably, the elastic member 25 is a compression spring. The plurality of elastic members 25 drive the abutment members 26 to keep in contact with and abut against the end face of the movable part 242, so that the dust sweeping member 24 can be quickly reset after moving or rotating relative to the movable seat 22, so that the dust shoveling part 241 remains in contact with and abuts against the bottom groove wall of the dust collecting groove 7.

Furthermore, two dust troughs 9 are provided on the ground for accumulating metal particles. These two dust troughs 9 are located on either side of the dust collecting trough 7 and on either side of the dust settling chamber 4. After the dust sweeper 24 discharges the metal particles it carries, the metal particles are collected in the dust troughs 9. In this embodiment, the wall of the dust trough 9, which is adjacent to the dust collecting trough 7, is preferably inclined upward toward the dust collecting trough 7, and this inclined surface is connected to the top of the wall of the dust collecting trough 7 to facilitate the transfer of metal particles.

The implementation principle of a polishing and rust removal machine for steel processing in the embodiment of the present application is as follows:

The moving device 2 drives the steel 1 in and out of the dust reduction room 4, and the polishing device 3 polishes and removes rust on the surface of the steel 1 in the dust reduction channel 41; a large amount of metal particles will be generated during the polishing and rust removal of the steel 1, and the rotation of the first impellers 313 and the second impellers 323 form an airflow in the dust reduction channel 41. The airflow suppresses the metal particles from forming dust, blows off the metal particles remaining on the surface of the steel 1, and drives the metal particles into the dust collecting trough 7. The airflow formed by the rotation of the third impellers 324 will drive the metal particles to gather in the dust collecting trough 7; during the sliding process of the movable seat 22, the dust sweeping member 24 will be driven to sweep the metal particles in the dust collecting trough 7 to the corner, and the dust shoveling part 241 will scoop up and pour out the metal particles, so that the metal particles leave the dust collecting trough 7 and enter the dust storage trough 9, which is convenient for the staff to clean the metal particles later.

The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
