DETAILED DESCRIPTION

To further illustrate, embodiments detailing a derusting machine are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

EXAMPLE 1

As shown in FIGS. 1-5, the disclosure provides a derusting machine. The derusting machine comprises at least two derusting wheels 1 which are perpendicular to each other, for example, one is disposed in the transverse direction of the derusting machine, and the other is disposed in the longitudinal direction of the derusting machine. Each of the at least two derusting wheels 1 comprises a plurality of wire wheels 11 and a rotating wheel 12, and the rotating wheel 12 is disposed between the wire wheels 11. The rotating wheel 12 comprises a carbide bit 13. Each of the at least two derusting wheels 1 is connected to a driving mechanism 2. The driving mechanism 2 is disposed in a handle 3. A dust hood 6 is attached to the derusting wheel 1. A plurality of suction nozzles 7 is disposed through the dust hood 6. The plurality of suction nozzles 7 is connected to a vacuum cleaner 9 through a pipe 8. Specifically, when the derusting wheels 1 are rotating, the plurality of wire wheels 11 contacts a steel plate directly to remove the rust on the steel plate. At the same time, the carbide bit 13 on the rotating wheel 12 scratches the steel plate longitudinally and transversely, which increases the surface roughness of the steel plate and makes the surface structure of the steel plate reach the cleanliness level Sa 2.5-3.0. The handle 3 where the driving mechanism 2 is disposed is compact, easy to carry, suitable for outdoor operation, thus improving the work efficiency, reducing the labor intensity of workers, saving the cost, and ensuring the product quality. The dust produced in the rust removal process is sucked into the suction nozzle 7, transported via the pipe 8, and stored in the vacuum cleaner 9. The dust hood 6 prevents the rust from being blown away by the wind, ensuring the health of the operators. The iron scraps can be recycled thus saving the costs and resources.

In the example, the driving mechanism 2 comprises a drive motor 21, a first driving wheel 22, a bearing seat 23, and a bevel gear set 24. The first driving wheel 22, the bearing seat 23, and the bevel gear set 24 are disposed on the output shaft of the drive motor 21 sequentially. Each of the at least two derusting wheels 1 comprises a rotating shaft 25. The rotating shaft of one derusting wheel is connected to the drive motor 21 in a transmission way via the bevel gear set 24. The rotating shaft of another derusting wheel is provided with a first driven wheel 26. The first driven wheel 26 is connected to the first driving wheel 22 in a transmission way via a belt. The rotating shaft is fixedly connected to an external mechanism through the bearing seat 23. Specifically, when the drive motor 21 is started, the first driving wheel 22 and the bevel gear set 24 are driven to rotate, thereby driving the rotating shaft 25 to rotate. Thus, the at least two derusting wheels 1 rotate to remove dust of the steel plate.

Specifically, the handle 3 comprises a housing 31, a charging interface 32, a switch button 33, and a hand-held part 34. A control circuit board and a storage battery are disposed in the housing 31. The vacuum cleaner 9 is disposed on the one end of the housing 31. The pipe 8 runs through the housing 31 to communicate with the vacuum cleaner 9. In certain embodiments, the size of the handle is similar to that of a hand-held cutting machine, which is easy to carry.

Specifically, the cutting surface of the carbide bit 13 comprises a plurality of elastic serrations, which is convenient to scratch the surface of the steel plate thus improving the work efficiency.

Specifically, the wire wheel 11 comprises a plurality of steel wires, and each steel wire comprises a bent free end. When the wire wheel rotates, the steel plate is shoveled by the steel wire, thus improving the dust removal efficiency.

Specifically, the derusting machine comprises a plurality of suction nozzles 7 equidistantly disposed and inclined towards the derusting wheels 1 to suck the rising iron filings and rust.

Specifically, the vacuum cleaner 9 comprises a detachable cylindrical dust collector, which is convenient for cleaning and recycling of the vacuum cleaner.

EXAMPLE 2

As shown in FIGS. 1-4 and 6, the disclosure provides a derusting machine. The derusting machine comprises at least two derusting wheels 1 which are perpendicular to each other, for example, one is disposed in the transverse direction of the derusting machine, and the other is disposed in the longitudinal direction of the derusting machine. The derusting wheel 1 comprises a plurality of wire wheels 11 and a rotating wheel 12, and the rotating wheel 12 is disposed between the wire wheels 11. The rotating wheel 12 comprises a carbide bit 13. The derusting wheel 1 is connected to a driving mechanism 2. The driving mechanism 2 is disposed on a conveyor 4. A dust hood 6 is attached to the derusting wheel 1. A plurality of suction nozzles 7 is disposed through the dust hood 6. The plurality of suction nozzles 7 is connected to a vacuum cleaner 9 through a pipe 8. Specifically, when the derusting wheel 1 is rotating, the plurality of wire wheels 11 contacts a steel plate directly to remove the rust on the steel plate. At the same time, the carbide bit 13 on the rotating wheel 12 scratches the steel plate longitudinally and transversely, which increases the surface roughness of the steel plate and makes the surface structure of the steel plate reach the cleanliness level Sa 2.5-3.0.

The conveyor 4 comprises a conveying frame 41. At least two derusting wheels 1 and two driving mechanisms are disposed on the conveying frame 41. The driving mechanisms are disposed correspondingly to the derusting wheels. The conveying frame 41 is disposed below the at least two derusting wheels 1. The conveying frame 41 is driven by a motor 42. The conveying frame 41 comprises a plurality of conveying rollers 43. One end of each conveying roller extends out of the conveying frame and a driving sprocket 44 is disposed on the one end. The driving sprockets 44 of the plurality of conveying rollers 43 are connected through a transmission chain 45. One of the plurality of conveying rollers is provided with a second driven wheel 46. A second driving wheel 47 is disposed around the output shaft of the motor 42. The second driving wheel 47 is connected to the second driven wheel 46 in a transmission way. The vacuum cleaner 9 is disposed on one side of the conveying frame 41. Specifically, the conveying frame 41 is configured to transport the steel plates to the derusting wheels for dust removal. When in operation, the motor 42 is started, and the second driving wheel 47 is driven to rotate, thereby driving the second driven wheel 46 to rotate. The rotation of the second driven wheel 46 drives the driving sprocket 44 coaxial with the second driven wheel to rotate. Because the driving sprockets 44 of the plurality of conveying rollers 43 are connected through the transmission chain 45, all the driving sprockets 44 start to rotate. Thus, the plurality of conveying rollers 43 start rotating to transport the steel plates.

Specifically, the cutting surface of the carbide bit 13 comprises a plurality of elastic serrations, which is convenient to scratch the surface of the steel plate thus improving the work efficiency.

Specifically, the derusting machine comprises a plurality of suction nozzles 7 equidistantly disposed and inclined towards the derusting wheels 1 to suck the rising iron filings and rust.

Specifically, the vacuum cleaner 9 comprises a detachable cylindrical dust collector, which is convenient for cleaning and recycling of the vacuum cleaner.

At the same time, the carbide bit 13 on the rotating wheel 12 scratches the steel plate longitudinally and transversely, which increases the surface roughness of the steel plate and makes the surface structure of the steel plate reach the cleanliness level Sa 2.5-3.0.

The support frame 5 comprises an operation platform 51, a linear guide rail 52, a slide rail 53, a mounting base 54, and a bearing support 55. The linear guide rail 52 and the slide rail 53 are disposed on two sides of the operation platform 51, respectively. The mounting base 54 is disposed on the linear guide rail 52. The driving mechanism 2 is disposed on the mounting base 54. The bearing support 55 is disposed on one end of the rotating shaft of the derusting wheel 1 back on the driving mechanism. The bearing support 55 is fixedly connected to the slide rail 53. The driving mechanism 2 drives the derusting wheels 1 to move on the linear guide rail 52. The vacuum cleaner 9 is disposed on one side of the operation platform 51. Specifically, the steel plate is disposed on the operation platform 51.
