In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0030] In this embodiment, as Figures 1 to 3As shown, the dust removal device is used to remove dust from items on the conveyor belt 60. The dust removal device includes: a dust cover, an ion air blowing assembly 20, a dust collection assembly, and an air blowing assembly. The dust cover is installed on the outside of the conveyor belt 60. The ion air blowing assembly 20 is connected to the dust cover. The dust collection assembly is connected to the dust cover and is located downstream of the ion air blowing assembly 20. The air blowing assembly is connected to the dust cover, and the air blowing assembly and the ion air blowing assembly 20 are spaced apart on the dust cover, as are the air blowing assembly and the dust collection assembly.

[0031] In this way, the dust cover reduces the contact between the packaging cans and dust or powdery products on the conveyor belt 60, and its placement facilitates the installation of the ion blowing assembly 20, the dust collection assembly, and the air blowing assembly. The ion blowing assembly 20 neutralizes the static electricity on the surface of the packaging cans by blowing out ionized air, thereby reducing the cans' ability to attract dust or powdery products. The dust collection assembly removes dust or powdery products from the surface of the packaging cans. The air blowing assembly blows away dust or powdery products from the surface of the packaging cans. Placing the dust collection assembly downstream of the ion blowing assembly 20 first reduces the packaging cans' ability to attract dust or powdery products before removing them, improving the dust collection efficiency and effectiveness. The dust removal device reduces the adhesion of dust or powdery products to the packaging cans, thereby improving product quality. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies that packaging cans are prone to adhering to dust or powdery products, thereby affecting product quality.

Through the signal connection between the controller and the positioning detection element 50, the dust removal device can automatically activate the ion air purging assembly 20 based on whether the packaging can is in position, achieving precise control and automation, improving production efficiency and equipment reliability, and reducing operating costs.

[0034] In this embodiment, the positioning detection element 50 is a photoelectric sensor.

[0035] like Figures 1 to 3As shown, the air purging assembly includes a first purging component and a second purging component spaced apart from the first purging component. The first purging component is located between the ion air purging assembly 20 and the dust collection assembly. The second purging component is located downstream of the dust collection assembly. The air purging assembly is designed to include both the first and second purging components, which increases the purging levels and allows for purging of the packaging can from different angles and positions, enabling more thorough removal of surface-adhered dust or powdery products and improving overall dust removal efficiency.

[0036] In other embodiments, the air purging assembly includes a first purging assembly and a second purging assembly spaced apart from the first purging assembly; the first purging assembly is located between the ion air purging assembly 20 and the dust collection assembly.

The second purging assembly includes a fourth nozzle 421 disposed on the first side wall 11, a fifth nozzle 422 disposed on the second side wall 12, and a sixth nozzle 423 disposed on the top wall 13. Thus, the arrangement of the fourth nozzle 421, the fifth nozzle 422, and the sixth nozzle 423 enables multi-angle purging of the packaging cans, improving dust removal efficiency.

The sixth nozzle 423 is located upstream of the fourth nozzle 421. This design allows for pre-treatment before dust collection, ensuring dust collection efficiency and effectiveness. There are multiple first nozzles 411, which are spaced apart vertically. The multiple first nozzles 411 are arranged at intervals along the vertical direction, enabling them to simultaneously sweep the surface of the packaging can along its height, thus improving dust removal effect and efficiency. Furthermore, the vertically spaced arrangement of the multiple first nozzles 411 accommodates packaging cans of different heights, enhancing the versatility and adaptability of the dust removal device.

[0040] In this embodiment, the first nozzle 411 and the second nozzle 412 are symmetrically arranged on both sides of the conveyor belt 60, and the third nozzle 413 is located downstream of the second nozzle 412.

The air blowing assembly includes a second blowing assembly, which includes a fourth nozzle 421 disposed on the first side wall 11, a fifth nozzle 422 disposed on the second side wall 12, and a sixth nozzle 423 disposed on the top wall 13; the sixth nozzle 423 is located upstream of the fourth nozzle 421. This arrangement ensures that after the packaging can is blew by the sixth nozzle 423, it undergoes further enhanced blowing by the fourth nozzle 421, effectively preventing dust or powdery products from rebounding and further improving the dust removal effect. The sixth nozzle 423's upstream location also allows for pre-treatment before dust collection, ensuring efficient and effective dust collection. Multiple fourth nozzles 421 are arranged at intervals along the vertical direction. The multiple fourth nozzles 421 are arranged at intervals along the vertical direction, enabling them to simultaneously sweep the surface of the packaging can along its height, thus improving dust removal effect and efficiency. Furthermore, the vertically spaced arrangement of the multiple fourth nozzles 421 accommodates packaging cans of varying heights, enhancing the versatility and adaptability of the dust removal device.

[0043] In other embodiments, the dust cover includes a top wall 13 located above the conveyor belt 60 and a first side wall 11 and a second side wall 12 located on both sides of the conveyor belt 60, respectively.
