[0038] Please refer to Figures 1-12As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a dust removal device suitable for the packaging industry. It includes a frame 10 and a transfer device 20 disposed on the worktable of the frame 10 for conveying workpiece 1. The transfer device 20 has a dust removal area 2 on the conveying path for stopping and removing dust from the workpiece 1. Two dust removal devices 30 are provided in the dust removal area 2, which are located above and below the transfer device 20, respectively. At least one dust removal device 30 includes a blowing mechanism 31 and a suction mechanism 32 disposed on the side of the blowing mechanism 31. The blowing end of the blowing mechanism 31 and the suction end of the suction mechanism 32 both face the workpiece 1.

[0039] A drive assembly 40 connecting two dust removal devices 30 is provided next to the dust removal zone 2. The drive assembly 40 includes at least one drive member 41, the displacement end of which is connected to the dust removal device 30. Driven by the drive member 41, the dust removal device 30 moves closer to / away from the workpiece 1. Compared with existing workpiece dust removal methods where operators use a vacuum cleaner's suction pipe or a handheld vacuum gun to move the workpiece surface to remove dust, this dust removal equipment, by setting the dust removal zone 2 on the conveying path of the transfer assembly 20, allows the transfer assembly 20 to transport the workpiece 1 to the dust removal zone 2. Based on the distance between the dust removal device 30 and the workpiece 1, the drive member 41 is activated, causing the displacement end of the drive member 41 to move the dust removal device 30 closer to the workpiece 1. This allows the dust on the workpiece 1 to be lifted by the blowing mechanism 31, and then removed by the suction mechanism 32. This efficiently removes dust from the workpiece surface and improves the cleanliness of the cleaned workpiece.

[0040] Specifically, to enhance the dust removal effect on workpiece 1, there are two dust removal devices 30, which are arranged one above the other. When workpiece 1 moves between the two dust removal devices 30, the blowing mechanism 31 and the suction mechanism 32 in the dust removal device 30 are both aligned with workpiece 1, thereby enhancing the dust removal effect of this dust removal equipment on workpiece 1.

[0041] like Figure 6 As shown, exemplarily, the dust removal device 30 also includes a housing 33, which has a cavity 331 facing the workpiece 1. An isolation seat 34 is provided on the cavity 331, forming a suction channel 35 between the isolation seat 34 and the housing 33. The suction end of the suction mechanism 32 is connected to the suction channel 35. The blowing mechanism 31 is located on the isolation seat 34 and surrounded by the suction channel 35. When the dust removal device 30 removes dust from the workpiece 1, the dust removal device 30 removes dust by blowing up the dust on the workpiece 1 through the blowing mechanism 31 and then extracting the dust-laden airflow through the suction mechanism 32. To prevent the dust blown by the blowing mechanism 31 from scattering across the workpiece 1 and affecting the processing environment, the blowing mechanism 31 and the suction mechanism 32 are housed within the housing 33.

[0042] Specifically, when the blowing mechanism 31 and the suction mechanism 32 are located inside the housing 33, they need to be separated by an isolation seat 34, and an air suction channel 35 is added between the isolation seat 34 and the housing 33, so that when the air blown out by the blowing mechanism 31 is not directly sucked up by the suction mechanism 32, but after contacting the workpiece 1, the dust on the workpiece 1 is picked up and then sucked up by the suction mechanism 32.

[0043] like Figure 5 As shown, exemplarily, the isolation seat 34 is provided with an air inlet channel 341; there are multiple air blowing mechanisms 31, which are arranged at intervals and all connected to the air inlet channel 341, and each air blowing mechanism 31 is rotatably mounted on the isolation seat 34. Because the air inlet channel 341 is connected to the outer tube provided on the housing 33, gas can flow into the suction mechanism 31 through the air inlet channel 341, so that the air blowing mechanism 31 can rotate under the blowing of gas, thereby enhancing the dust-raising effect after the air blowing mechanism 31 blows onto the workpiece 1, and enabling the suction mechanism 32 to achieve a better dust removal effect after extracting the dust carried by the air blowing mechanism 31.

[0044] like Figure 9 As shown, exemplarily, the air blowing mechanism 31 includes a pneumatic shaft 311 and a rotating nozzle 312 sleeved on the pneumatic shaft 311. The pneumatic shaft 311 and the rotating nozzle 312 are connected by a rotating shaft assembly 313. The pneumatic shaft 311 communicates with the air inlet channel 341. The rotating shaft assembly 313 is located between the rotating nozzle 312 and the pneumatic shaft 311. When the airflow enters the pneumatic shaft 311, due to the exhaust direction of the rotating nozzle 312 and the rotation direction of the rotating nozzle 312, the airflow exits from the point where it enters the rotating nozzle 312 through the pneumatic shaft 311, causing the rotating nozzle 312 to rotate around the rotating shaft assembly 313. The rotation of the rotating nozzle 312 increases the diffusion speed of the gas, thereby enhancing the dust-removing effect of the air blowing mechanism 31.

[0045] Specifically, the rotary nozzle 312 is equipped with multiple branch pipes 3121 corresponding to the workpiece 1, and the air outlets of the multiple branch pipes 3121 correspond to different positions of the workpiece 1. Because the rotary nozzle 312 has interconnected branch pipes 3121, when the rotary nozzle 312 rotates, the air outlets of the branch pipes 3121 are aligned with the workpiece 1 so that the sprayed gas can directly contact the workpiece 1. In addition, in conjunction with the rotation of the rotary nozzle 312, a tornado-like airflow is formed to further clean the stubborn residue on the workpiece 1.

[0046] like Figure 6As shown, exemplarily, the isolation seat 34 has a recessed cavity 342 on one side corresponding to the workpiece 1. Plasma air bars 36 are provided on both sides of the cavity 342. Multiple air blowing mechanisms 31 are equally spaced within the cavity 342 and located between the two plasma air bars 36. The arrangement of the plasma air bars 36 within the cavity 342, and the static electricity removal effect of the plasma air bars 35 themselves, ensures that the gas discharged from the plasma air bars 35, after contacting the dust-laden gas within the cavity 342, effectively prevents dust from adhering to the isolation seat 34, the housing 31, and the workpiece 1, further improving the dust removal efficiency of this dust removal equipment.

[0047] Specifically, the plasma fan bar 36 is located near the suction channel 35, and the air outlet of the plasma fan bar 36 faces the workpiece 1. Because the air outlet of the plasma fan bar 36 corresponds to the workpiece 1, and the plasma fan bar 36 is located near the suction channel 35, the air blown by the blowing mechanism 31 will mix with the air discharged through the plasma fan bar 36 before entering the suction channel 35, thereby increasing the dust collection effect of the suction mechanism 32.

[0048] like Figure 2 As shown, exemplarily, the transfer assembly 20 includes two guide rails 21 mounted on the worktable of the frame 10, a transfer mesh plate 22 sliding on the guide rails 21, and a first driving member 23 for moving the transfer mesh plate 22. The dust removal device 30 is located between the two guide rails 21, and the workpiece 1 is placed on the transfer mesh plate 22. When removing dust from the workpiece on the transfer mesh plate 22, the first driving member 23 moves along the guide rails 21. When it moves to the dust removal area 2, the dust on the workpiece is blown up by the blowing assembly 31 and then extracted by the suction assembly 32.

[0049] The transfer mesh plate 22 is located between the two dust removal devices 30.

[0050] like Figure 12 As shown, for example, the drive component 41 is a ball screw installed in the frame 10. The drive assembly 40 also includes a second drive component 42 that drives the ball screw to run, and a connecting plate 43 that is sleeved on the nut seat of the ball screw. The connecting plate 43 is connected to the dust removal device 30. When the transfer mesh plate 22 moves the workpiece 1 to the dust removal area 2, the second drive component 42 drives the ball screw to rotate, causing the nut seat 411 on the ball screw to move the connecting plate 43 up and down, thereby adjusting the distance between the housing 33 and the workpiece 1, thereby improving the dust removal effect of the dust removal device 30 on the workpiece.

[0051] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
