[0036] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Example 1

[0038] Reference Figure 1 , provides a schematic diagram of the overall structure of the air inlet wind direction adjustment structure and the double-blowing wind field, such as Figure 1-3 , an air inlet wind direction adjustment structure, comprising:

[0039] The wind guide component 100 includes a wind frame 101, wherein a wind guide plate 102 is disposed inside the wind frame 101, and a wind guide plate 2 103 is disposed inside the wind frame 101 below the wind guide plate 102, and longitudinal strips 104 penetrating the wind guide plate 102 and the wind guide plate 2 103 are equidistantly and vertically fixed inside the wind frame 101, and strip grooves 105 are provided on the surfaces of the wind guide plate 2 103 and the longitudinal strips 104 at positions corresponding to the longitudinal strips 104;

[0040] An adjusting component 106 for driving the second air guide plate 103 and the longitudinal strip plate 104 to swing synchronously is provided on one side of the air frame 101 .

[0041] Furthermore, a pin is fixed on the inner side of the strip groove 105 , and the pin passes through the longitudinal strip plate 104 .

[0042] Specifically, the length of the strip groove 105 is greater than the width of the longitudinal strip plate 104, so that the air guide plate 1 102 and the air guide plate 2 103 will not interfere with each other when rotating;

[0043] Furthermore, the adjustment component 106 includes a rotating rod 106a rotatably connected to the bottom of the wind guide plate 102 and a rotating rod 106b rotatably connected to the upper surface of the wind guide plate 103. A rectangular groove 106c is formed through the surface of the rotating rod 106a, and a linkage column 106d is formed through the rotating rod 106b.

[0044] Specifically, the linkage column 106d is rotationally connected to the rotating rod 106b, and the linkage column 106d passes through the rectangular groove 106c. Under the dead weight of the wind guide plate 102, the upper end of the rectangular groove 106c is always above the linkage column 106d, and the linkage column 106d is used to support the wind guide plate 102, which is a steel material component.

[0045] Furthermore, an eccentric rod 106e is fixed to one end of the linkage column 106d, and the eccentric rod 106e is driven by an angle motor 106f.

[0046] Specifically, a receiving opening is provided on one side of the wind frame 101, and the angle motor 106f is installed in the receiving opening. The angle motor 106f drives the eccentric rod 106e to make a circular motion. When the eccentric rod 106e makes a circular motion, it drives the linkage column 106d to move synchronously. When the linkage column 106d moves, it moves upward counterclockwise or downward clockwise.

[0047] When moving counterclockwise, the rectangular slot 106c will push the wind guide plate 102 upward to rotate with the shaft as the fulcrum, and the rotating rod 106b connected to the linkage column 106d will drive the wind guide plate 103 to move upward synchronously, thereby changing the upward angles of the wind guide plates 102 and 103;

[0048] When moving clockwise, the linkage column 106d drives the wind guide plate 103 to rotate downward through the rotating rod 106b, and at the same time, under the deadweight of the wind guide plate 102, it automatically rotates downward with the rotating shaft as the fulcrum until the upper end of the rectangular groove 106c fits on the linkage column 106d to form a support for the wind guide plate 102, thereby completing the downward angle adjustment of the wind guide plate 102 and the wind guide plate 103. The angle adjustment of the wind guide plate 102 and the wind guide plate 103 can meet the needs of different wind directions, thereby increasing practicality.

[0049] Example 2

[0050] Reference Figure 4 , this embodiment is different from the first embodiment in that: the air guide component 100 further includes a blocking component 107, and the blocking component 107 is arranged inside the air frame 101;

[0051] The sealing component 107 includes slots 107a symmetrically opened at the top and bottom of the inner side of the wind frame 101, a guide column 107b is fixed inside the slot 107a, a sliding seat 107c is slidably sleeved on the outside of the guide column 107b, a sealing plate 107d is rotatably connected to the sliding seat 107c, and a spring 107e is sleeved on the outside of the guide column 107b.

[0052] Specifically, the two ends of the spring 107e are fixedly connected to the slide 107c and one end of the slot 107a respectively. When the spring 107e is not subjected to force, the slide 107c moves to the middle section of the guide column 107b. As the air guide plate 102 and the air guide plate 2 103 rotate, the tail portion will contact the sealing plate 107d, so that the slide 107c slides and moves along the guide column 107b, and the spring 107e is stretched and subjected to force.

[0053] Furthermore, the inner side of the sealing plate 107d is stretched and connected to the inner side of the wind frame 101 through a stretching member 107f.

[0054] Specifically, the stretching member 107f includes two rotating seats, one of which is fixed to the wind frame 101 and one end of the displacement slot 107a, and the other is rotatably fixed to the inner side of the sealing plate 107d. A rotating block is rotatably connected inside the rotating seat, and the two rotating blocks are stretched by spring 2. When the air guide plate 102 and the air guide plate 103 rotate, their tails touch the sealing plate 107d, causing the sealing plate 107d to rotate with the rotating connection point on the sliding seat 107c as the fulcrum, thereby causing the angle to change, so that the inner side of the sealing plate 107d is always in contact with one end of the air guide plate 102 and the air guide plate 103, thereby blocking other spaces inside the wind frame 101, so that the wind can only be discharged from the space between the air guide plate 102 and the air guide plate 103, reducing the dispersion of the wind, and increasing the flow rate of the wind and the accuracy of the direction.

[0055] The rest of the structure is the same as that of Example 1.

[0056] Example 3

[0057] Reference Figure 5 , this embodiment is different from the above embodiment in that: this embodiment discloses a double-blowing wind field, including the above-mentioned air inlet wind direction adjustment structure, and also includes:

[0058] The printing chamber component 200 includes a chamber 201, a printing area 202 is provided at the inner bottom of the chamber 201, and a deposition groove 203 is provided at the inner bottom of the chamber 201 at one side of the printing area 202, and two air inlets 204 and air outlets 205 are respectively provided at two sides of the chamber 201;

[0059] The ventilation component 300 is disposed on the chamber 201 to form an air flow field therein that connects the air inlet 204 and the air outlet 205 .

[0060] Furthermore, the ventilation component 300 includes an air collecting hood 301 installed on the outside of the air inlet 204, an air exhaust hood 302 installed on the outside of the air outlet 205, an upper guide block 303 installed on the top of the chamber 201 and close to the air outlet 205, and a lower guide block 304 fixed on the inside of the chamber 201 and located above the bottom air outlet 205.

[0061] Specifically, a fan is installed in the wind collecting cover 301, and the wind generated by the fan is blown into the chamber 201 from the air inlet 204;

[0062] Specifically, the upper guide block 303 is a triangular structure, and the inclined surface of the upper guide block 303 is arranged opposite to the upper air inlet 204. When wind blows in from the air inlet 204, the trajectory of the wind will be toward the guide block 303. The guide block 303 is an inclined structure. The wind changes its trajectory along the inclined surface. Part of the wind is discharged between the upper air outlet under the action of gravity, and the other part will hit the lower guide block 304 downward along the inclined surface.

[0063] Specifically, the lower guide block 304 is composed of an arc segment, an upwardly inclined segment and a downwardly inclined segment. The wind hitting the lower guide block 304 will change its trajectory to a vertically upward direction along the slope of the upwardly inclined segment and along the conversion of the arc segment, and then be discharged between them under the gravitational effect of the upper air outlet, forming a first wind field.

[0064] The wind from the bottom air inlet 204 will directly flow toward the bottom air outlet 205 to form a second wind field. This structure forms an upper and lower wind field in the chamber 201, and the upper and lower wind fields are independent, which increases the air flow in the chamber, allowing the metal dust to be better removed and improving the metal dust removal efficiency.

[0065] The rest of the structure is the same as that of Example 2.
