[0029] Preferably, the thickness of the air knife body 1 is not greater than 1 / 2 of the height of the opening 7.

[0030] Preferably, it also includes a front cutting cavity 8 with a conveying roller 9, and there is a gap between the front cutting cavity 8 and the rear cutting cavity 6, so that the conveying roller 9 can cause the material to pass through the gap.

[0031] Preferably, one end of the air knife body 1 is provided with a rotating movable part 10 to adjust the air outlet angle of the air knife body 1.

[0032] Preferably, the rotating movable part 10 is connected to a driving part 11, which causes the air knife body 1 to rotate.

[0033] Preferably, the thickness of the air knife body 1 is not greater than 1 / 3 of the height of the opening 7.

[0034] Preferably, the end of the vent 4 near the guide cavity 3 is wider on the outside and narrower on the inside;

[0035] The end of the air outlet 4 away from the guide cavity 3 is designed to be narrower on the inside and wider on the outside.

[0036] Preferably, the inner wall of the guide cavity 3 is inclined so that the airflow is directed toward the outlet 4.

[0037] Preferably, the adsorption component 13 includes an exhaust unit and an exhaust pipe, with both ends of the exhaust pipe connected to the exhaust unit and the rear wall of the rear cutting cavity 6, respectively.

[0038] The working principle of this utility model:

[0039] This utility model has a reasonable design and simple structure. One end of the adsorption component 13 is positioned opposite to the air knife body 1 located in front of the opening 7 of the rear cutting cavity 6, which facilitates dust removal, ventilation and air supply. The air knife body 1 has a dust removal function and its air output is uniform. It is provided with a clearance groove 5, which facilitates installation at the air inlet or air outlet and avoids blocking the air inlet or air outlet.

[0040] In this embodiment, the air knife body 1 can be supplied with airflow through the air inlet 2. After passing through the air inlet 2, the airflow enters the guide cavity 3 and is guided along the inclined surface of the guide cavity 3 to multiple air outlets 4, achieving uniform air output. As shown in Figure 2, the diameter of the air outlets 4 is set from wide to narrow and then from narrow to wide from the end near the guide cavity 3 to the end away from the guide cavity 3 (from left to right). Within the guide cavity 3, the airflow can be guided to converge and be output through each air outlet 4. The outermost end of the air outlet 4 widens from narrow to wide, which promotes efficient airflow output. As shown in Figure 3, multiple air outlets 4 are evenly distributed on the side wall of the air knife body 1, and both the upper and lower end faces are provided with clearance grooves 5 to avoid obstructing the longitudinal flow of airflow. As shown in Figure 4, the air knife body 1 can be manually rotated by the rotating movable part 10 to adjust the output angle of the air outlet, thereby blowing air to remove dust from the electrode sheet 12. In this embodiment, the adsorption component 13 can be a suction unit and a suction pipe. One end of the suction pipe is set opposite to the air knife body 1. The air knife body 1 can blow away the fragments of the laser-cut electrode sheet 12. The driving component 11 can drive the rotating movable part 10 and the air knife body 1 to rotate, thereby adjusting the air outlet angle. In this embodiment, the conveying roller 9 is used to convey the electrode sheet 12. The gap between the front cutting cavity 8 and the rear cutting cavity 6 is through which the electrode sheet 12 passes. The laser can horizontally cut the electrode sheet 12 from the rear cutting cavity 6. The rear cutting cavity 6 is hollow, and the airflow of the air knife body 1 can pass through the interior of the rear cutting cavity 6 and flow into the suction pipe. The front cutting cavity 8 can be provided with a cylindrical belt and an adsorption structure to realize the close-fitting conveying of the electrode sheet 12. In this embodiment, the electrode sheet 12 is conveyed from top to bottom or from bottom to top in Figure 4. In this embodiment, the material is the electrode sheet 12. The rotating movable part 10 can be a hollow ring structure, which enables the air knife body 1 to rotate without interfering with the air intake 2. The dashed box in Figure 4 indicates the location of the exhaust pipe.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
