It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0027] Please refer to the following: Figures 1 to 4 The cleaning device provided in this application includes a lifting mechanism 10, a device body 20, a roller brush 30, a drive mechanism 40, and a dust collector (not shown). The movable end of the lifting mechanism 10 is connected to the device body 20. The device body 20 has a suction port 211 and a suction chamber 21. The roller brush 30 is rotatably disposed on the device body 20. The roller brush 30 is located in the suction chamber 21 and partially exposed in the suction port 211. The drive mechanism 40 is disposed on the device body 20 and connected to the roller brush 30 to drive the roller brush 30 to brush the dust on the surface of the product. The dust collector is disposed on the device body 20 and is directed towards the suction port 211 to draw dust into the suction chamber 21. With this design, the lifting mechanism 10 can be fixed to the cutting machine tool. After the cutting platform cuts the product, it moves to the bottom of the cleaning device. The lifting mechanism 10 drives the main body 20 to descend, so that the roller brush 30 contacts the product surface on the cutting platform. At this time, the drive mechanism 40 drives the roller brush 30 to brush the dust on the product surface. The dust collector sucks the dust on the product surface into the suction chamber 21, which can effectively clean the dust on the product surface and ensure product quality.

[0028] like Figures 5 to 7 As shown, in some embodiments, the cleaning device may further include a dust collection hood 50, which has a dust discharge port 511 and a dust collection chamber 51. The dust collection hood 50 is connected to the main body 20 of the device, and the dust collection chamber 51 is connected to the suction chamber 21. A vacuum cleaner is located outside the dust collection chamber 51 and draws air from the dust discharge port 511 toward the dust collection chamber 51. With this design, the dust collection chamber 51 can collect the dust in the suction chamber and guide it to the vacuum cleaner for better dust removal.

[0029] Furthermore, the dust outlet 511 is located at the farthest end from the suction chamber 21. The cross-sectional area of ​​the dust collection chamber 51 decreases from the point of connection with the suction chamber 21 to the dust outlet 511, and this decrease can be gradual or abrupt. With this design, because the cross-sectional area of ​​the dust collection chamber 51 decreases from the point of connection with the suction chamber 21 to the dust outlet 511, when the airflow flows from the point of connection with the suction chamber 21 to the dust outlet 511, according to Bernoulli's principle, the airflow velocity increases significantly as the cross-sectional area decreases. The high-speed airflow in the dust collection chamber 51, far from the suction chamber 21, creates a strong negative pressure zone, generating a stronger adsorption force on the dust, and quickly drawing the dust into the dust collection chamber 51.

[0030] Specifically, the dust collection hood 50 is triangular in shape with decreasing width from its connection point with the main body 20 to the direction away from the main body 20, and the dust collection chamber 51 is triangular in shape with decreasing width from its connection point with the suction chamber 21 to the direction away from the suction chamber 21. With this design, during vacuuming, the converging triangular structure can gather the dispersed airflow to the pointed dust outlet 511, increasing wind speed and suction power through the principle of cross-sectional area contraction in fluid mechanics. Simultaneously, the stable geometric structure of the triangle reduces deformation of the dust collection hood 50 caused by airflow impact during vacuuming. Combined with the optimized airflow profile via the guide surface, this reduces energy loss and noise generated by turbulence, significantly improving vacuuming efficiency and cleaning effect.

[0031] In some embodiments, the main body 20 of the device is a long strip structure, with its length extending in the horizontal direction X. The movable end of the lifting mechanism 10 is connected to the top of the main body 20, the drive mechanism 40 is connected to one end of the main body 20, the dust collection hood 50 is connected to one side of the main body 20, and the suction port 211 is located at the bottom of the main body 20. This design, with the lifting mechanism 10, drive mechanism 40, dust collection hood 50, and suction port 211 positioned at different orientations of the main body 20, avoids interference during installation and use, ensuring that the structures do not affect each other and contributing to a more compact structure for the cleaning device.

[0032] In some embodiments, the cleaning device may also include a coupling 60, through which the drive mechanism 40 is connected to the roller brush 30. With this design, the coupling 60 serves as a crucial link between the power source and the actuator in the cleaning device, enhancing the reliability, durability, and ease of maintenance of the equipment through torque transmission, offset compensation, and impact buffering.

[0033] In some embodiments, in order to enable the lifting mechanism 10 to be installed on the cutting machine tool, the cleaning device may also include a mounting component 70, the fixed end of the lifting mechanism 10 is fixed to the mounting component 70, and the mounting component 70 is installed on the cutting machine tool to fix the lifting mechanism 10 to the cutting machine tool.

[0034] In some embodiments, the roller brush 30 may include a spindle 31 and a brush 32. The two ends of the spindle 31 are rotatably connected to the device body 20. A drive mechanism 40 is connected to the spindle 31. The brush 32 is sleeved on the spindle 31 and used to brush dust off the surface of the product. With this design, during use, the drive mechanism 40 drives the spindle 31 to rotate, and the spindle 31 drives the brush 32 to rotate, thereby brushing dust off the product surface.

[0035] Among them, the mandrel 31 can be made of stainless steel; the brush 32 can be made of anti-static material, soft material, does not shed bristles and does not generate dust.

[0036] Furthermore, the roller brush 30 may also include two bearings 33, with both ends of the spindle 31 connected to the device body 20 via the bearings 33. This design reduces frictional resistance between the spindle 31 and the device body 20, minimizing wear. When the roller brush 30 is in operation, it may be subjected to impact forces from the object being cleaned or other components; the bearings 33 can buffer and absorb these impact forces to a certain extent, protecting the spindle 31 and the device body 20 from damage.

[0037] Furthermore, in order for the brush 32 to rotate with the spindle 31, the roller brush 30 may also include two locking rings 34, both of which are sleeved on the spindle 31 and respectively abut against the two ends of the brush 32 to fix the brush 32 to the spindle 31.

[0038] In some embodiments, the lifting mechanism 10 may include a cylinder 11 and a movable part 12. The cylinder 11 is fixed to the cutting machine tool, and the movable part 12 is movably disposed on the cylinder 11. The movable part 12 is connected to the device body 20 to drive the device body 20 to rise and fall relative to the cylinder 11.

[0039] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and concept of this application, and all such substitutions or changes should fall within the protection scope of the appended claims.
