[0027] Figure 1 is a schematic structural diagram of a wind nozzle in an embodiment of the present utility model, as Figure 1 shown, and referring to Figures 2 to 5 , an embodiment of the present utility model provides a wind nozzle 10 for an oven, including a first housing 100 and an adjustment screen plate 200. An air inlet is provided at one end of the first housing 100, and the air inlet is communicated with the air cavity of the oven; an air outlet is provided at the other end of the first housing 100; the adjustment screen plate 200 is movably arranged in the first housing 100 for covering the air outlet; a communication port is provided on the adjustment screen plate 200, and the communication port is communicated with the air outlet. When the adjustment screen plate 200 moves along the length direction of the first housing, the communication area between the communication port and the air outlet is adjustable.

[0028] In the embodiment of the present utility model, since a movable adjustment screen plate 200 is arranged in the first housing 100, the communication area between the communication port and the air outlet is controlled by moving the adjustment screen plate 200, thereby controlling the air volume output of the wind nozzle 10. During application, a plurality of wind nozzles 10 are evenly arranged in the drying channel 630 of the oven. By controlling the air volume output of one or more wind nozzles 10, the air volume output of the hot air in this area can be controlled, so that the air volume of the hot air in the entire drying channel 630 is uniform, thereby improving the drying quality of the oven.

[0029] In an embodiment of the present utility model, the air nozzle 10 further includes a fixing assembly 300. The fixing assembly 300 is connected between the adjusting mesh plate 200 and the first housing 100 for fixing the adjusting mesh plate 200 on the first housing 100. During application, after moving the adjusting mesh plate 200 to a predetermined position, the adjusting mesh plate 200 is fixed at the position by the fixing assembly 300, so as to keep the communication area of the air outlet stable, so that the air nozzle 10 can blow air stably.

[0030] Specifically, the fixing assembly 300 includes a fixing plate 310, a stud 320, an adjusting nut 330 and a spring 340. The fixing plate 310 is vertically arranged on the adjusting mesh plate 200, and a through hole is provided on the fixing plate 310; the stud 320 extends along the length direction of the adjusting mesh plate 200, one end of the stud 320 is fixed on the side wall of the first housing 100, and the other end passes through the through hole and is screwed with the adjusting nut 330, and the nut abuts against the fixing plate 310; the spring 340 is sleeved on the stud 320, and both ends of the spring 340 respectively abut against the fixing plate 310 and the side wall of the first housing 100.

[0031] When the embodiment of the present utility model is applied, by rotating the adjusting nut 330, the adjusting nut 330 can be moved along the axial direction of the stud 320. When moving in the direction close to the side wall of the first housing 100, the adjusting mesh plate 200 can be driven to move through the fixing plate 310, so as to realize the effect of regulating the communication area of the air outlet. Through the arrangement of the spring 340, when the nut moves in the direction away from the side wall of the first housing 100, the spring 340 returns from the compressed state, thereby pushing the fixing plate 310 and driving the adjusting mesh plate 200 to move in the reverse direction to regulate the communication area of the air outlet. Moreover, the spring 340 can generate a pre-tightening force between the adjusting mesh plate 200 and the side wall of the first housing 100, avoiding the spontaneous movement of the adjusting mesh plate 200, so as to ensure that the communication area of the air outlet remains stable.

[0032] As Figure 2 shown, in an embodiment of the present utility model, the air outlet includes a plurality of air outlet holes 120 provided on the bottom plate 110 of the first housing 100, and the plurality of air outlet holes 120 are arranged in an array along the length direction and the width direction of the adjusting mesh plate 200; the adjusting mesh plate 200 is a rectangular sheet metal part, and the communication port includes a plurality of communication holes 210 provided on the adjusting mesh plate 200, and the communication holes 210 are arranged in one-to-one correspondence with the air outlet holes 120.

[0033] As Figure 3 、 Figure 4As shown, in an embodiment of the present utility model, the air nozzle 10 further includes a second housing 400. The second housing 400 is movably sleeved on the first housing 100. One end of the second housing 400 away from the first housing 100 is provided with an air guide port 410, and the air guide port 410 is communicated with the air outlet. During application, the hot air flowing out from the air outlet enters the second housing 400 and flows into the drying channel 630 through the air guide port 410. Since the second housing 400 is movably arranged on the first housing 100, the distance between the air guide port 410 and the substrate in the drying channel 630 can be changed by moving the second housing 400, so as to adjust the temperature when the hot air blows onto the surface of the substrate and improve the drying quality of the oven.

[0034] Specifically, the second housing 400 is provided with a kidney-shaped hole 420 extending along its moving direction or the air outlet direction of the air outlet. The first housing 100 is provided with fixing holes corresponding to the kidney-shaped holes 420 one by one. A fixing bolt 500 is connected between the kidney-shaped hole 420 and the fixing hole. During application, loosen the fixing bolt 500, and the second housing 400 can be moved. The fixing bolt 500 slides in the kidney-shaped hole 420. After moving the second housing 400 to a suitable position, the fixing bolt 500 can be tightened to keep the second housing 400 at the current position.

[0035] Further, the fixing bolt 500 includes a fixing nut and a fixing screw. The fixing nut is located inside the first housing 100.

The air guide ports 410 are provided on both the first inclined plate 430 and the second inclined plate 440. With such a setting, the air outlet blows out obliquely, avoiding the hot air blowing directly on the substrate, causing the substrate to shake and affecting the drying effect.

[0037] As Figure 5 shown, the present utility model also provides an oven, including an oven housing 600 and the air nozzle 10 in any one of the above embodiments, so as to have all the effects of the air nozzle 10. The air nozzle 10 is arranged inside the oven housing 600.

[0038] In an embodiment of the present utility model, the oven housing 600 includes an upper housing 610 and a lower housing 620.
