Description

[0002] In current double-sided coating equipment for diaphragms, the floating nozzle is a key component, and its performance directly affects the coating surface quality. However, existing floating nozzles have significant drawbacks: they primarily focus on providing upward buoyancy to support and suspend the diaphragm, neglecting the importance of effectively flattening the diaphragm along its width. This limitation leads to diaphragm vibration along its width during coating, resulting in phenomena such as rib formation and unstable edges. These problems directly affect the uniformity of coating and the quality of the final product.

[0026] Reference Figures 1 to 4The utility model provides a kind of adjustable covering formula lateral flattening air nozzle device, it includes air nozzle main body 1 and sheltering part 2.Wherein air nozzle main body 1 is the main part of entire device, air nozzle main body 1 there is air uniformizing chamber 13 and with air uniformizing chamber 13 being communicated air inlet 11 and air outlet 12.By air inlet 11 to air uniformizing chamber 13 inside send in hot air, hot air diffuses in air uniformizing chamber 13, air uniformizing chamber 13 to the hot air that pass in plays the role of uniform wind pressure, hot air after air uniformizing chamber 13 from air outlet 12 blows out, then act on diaphragm, produce support force to diaphragm, realize the suspension support of diaphragm.Sheltering part 2 slidingly set in the both ends of air inlet 11 of air nozzle main body 1, to sheltering part 2 division air inlet 11, and both sides sheltering part 2 can be unfolded or can be folded and set along the length direction of air nozzle main body 1, by adjusting how much sheltering part 2 unfolds or folds, to adjust the sheltering range of both sides of air inlet 11, and then adjust the effective air intake range of air inlet 11.

[0027] Sheltering part 2 is set at air inlet 11, hot air enters from air inlet 11 after diffusing in air uniformizing chamber 13, hot air diffuses to both sides before blowing out from air outlet 12, forms lateral spreading force.By flexibly adjusting the range of both sides of air inlet 11, the wind pressure of both sides of air outlet can be effectively reduced, so that while not changing main floating force, the flattening force of both sides is generated, effectively reduce the phenomenon that diaphragm shakes along membrane width direction due to that wind pressure of both sides of air outlet is too large, cause such as rib, edge instability etc.By setting the sheltering part 2 that can be unfolded or can be folded along the length direction of air nozzle main body 1, to constitute partial sheltering to air inlet 11, so as to change the effective air intake area of air inlet 11 according to the unfolding position of sheltering part 2 to adjust, to flexibly respond to the different needs of different width diaphragm to lateral spreading force.

[0028] Further, one end (i.e. fixed end) of the shielding part 2 is connected with the end of the tuyere body 1, and the other end (i.e. movable end) is movably arranged along the length direction of the tuyere body 1. In an embodiment, a rotating shaft 3 is arranged on the tuyere body 1, and the rotating shaft 3 is rotatably arranged on the tuyere body 1, and the axial direction of the rotating shaft 3 is parallel to the length direction of the tuyere body 1. Specifically, one end of the rotating shaft 3 is connected with one side end of the tuyere body 1, and the other end extends out of the tuyere body 1. A transmission block 21 is arranged on the rotating shaft 3, and the transmission block 21 is rotatably connected with the rotating shaft 3, and the transmission block 21 is located in the tuyere body 1, and the movable end of the shielding part 2 (i.e. the end away from the end of the tuyere body 1) is connected to the transmission block 21. The transmission block 21 is rotatably arranged on the rotating shaft 3, and the movable end of the shielding part 2 is connected to the transmission block 21, and the operator can rotate the rotating shaft 3 to cause the relative movement between the transmission block 21 and the rotating shaft 3. Since the rotating shaft 3 only rotates relative to the tuyere body 1 and does not move axially, the movement of the transmission block 21 in the uniform wind cavity 13 is realized, thereby driving the movable end of the shielding part 2 to move relative to the fixed end of the shielding part 2, realizing the change of the shielding range of the air inlet 11, and further changing the air pressure on both sides of the air outlet.

[0029] Further, the rotating shaft 3 includes a left threaded segment 31, a right threaded segment 32 and a shaft coupling 33, and the left threaded segment 31 and the right threaded segment 32 are fixedly connected through the shaft coupling 33.

In the embodiment, the thread rotation directions of the left threaded segment 31 and the right threaded segment 32 are oppositely arranged. The two transmission blocks 21 are respectively mounted on the left nut 311 and the right nut 321, and the structures on both sides of the shaft coupling 33 are mirror images. That is, by rotating the rotating shaft 3, the transmission blocks 21 on both sides will move towards each other or away from each other, thereby driving the shielding parts 2 on both sides to unfold or fold.

[0030] Further, one end of the rotating shaft 3 is connected with a hand wheel 4, and the hand wheel 4 is located outside the tuyere body 1. Specifically, the rotating shaft 3 is rotatably connected with a support block 34 at both ends, and the support blocks 34 on both sides are fixedly connected to the two ends of the tuyere body 1.

The hand wheel 4 is fixedly mounted on the other side end of the rotating shaft 3. By arranging the hand wheel 4, the rotation of the rotating shaft 3 can be realized by rotating the hand wheel 4, thereby effectively reducing the operation difficulty.

[0031] In some embodiments, the shielding part 2 is a concertina structure arranged along the length direction of the air nozzle body 1, and the change of the effective air inlet area of the air inlet 11 is realized by the unfolding and folding of the concertina structure through the movement of the transmission block 21.

The air inlet 11 and the air outlet part 12 are arranged on opposite sides of the shell 14, and the uniform air chamber 13 is located between the air inlet 11 and the air outlet part 12. The first uniform air plate 131 is arranged on the side of the air nozzle body 1 close to the air inlet 11, and the first uniform air plate 131 is uniformly provided with air outlet holes; the second uniform air plate 132 is arranged on the side of the air nozzle body 1 close to the air outlet part 12, and the second uniform air plate 132 is uniformly provided with air outlet holes on both sides along the length direction of the air nozzle body 1.
