[0002] "Household appliance plate" generally refers to the plate that is part of household appliances in the household appliance industry. When it is a high-end household appliance plate, it needs to have characteristics such as corrosion resistance and rust prevention. In order to ensure that the plate has the following advantages, it needs to be galvanized during production. When galvanizing, in order to make the galvanized film evenly cover the surface of the steel plate, an air knife is needed to assist in blowing air to blow away the excess galvanizing raw materials, so as to ensure the uniformity and smoothness of the galvanized surface.

[0003] The existing air knife system generates air flow by connecting a blower. The air flow is transported inside the air knife and ejected from the air blowing port to form a high-pressure air flow to assist in galvanizing the steel plate.

At this time, the wind tunnel 8 will be opened. On the contrary, the wind tunnel 8 will be reduced.

[0032] Furthermore, the angle adjustment unit includes a mounting ring 40. The mounting ring 40 is rotatably installed on the surface of the first-stage intake pipe 2.

[0033] With the above structure, four mounting holes are installed on the inner wall of the mounting ring 40, which are respectively located at the four vertex positions. The surface of the first-stage intake pipe 2 rotatably connected thereto is provided with annularly equally spaced positioning grooves 43. The positioning grooves 43 are hemispherical and match the positioning balls 42. The pipe body 1 drives the two first-stage intake pipes 2 to rotate. The two first-stage intake pipes 2 squeeze the positioning balls 42 through the positioning grooves 43 on the surface, causing the positioning balls 42 to disengage from the positioning grooves 43 and guiding them to the next positioning groove 43. When aligned with the next positioning groove 43, the positioning balls 42 are pushed into the positioning grooves 43 by the springs 41 to complete repositioning, that is, to complete a single angle adjustment.

[0034] Furthermore, a clamping block 25 is fixedly installed on the surface of the mounting ring 40. A connecting rod 24 is fixedly installed on the lower side of the clamping block 25.

Both ends of the bidirectional lead screw 46 are rotatably installed with the same mounting frame 14.

[0035] With the above structure, two clamping blocks 25 are installed on the surfaces of both mounting rings 40. By approaching each other, the clamping blocks 25 can be fixedly installed on the surface of the mounting ring 40. There are two sets of thread lines with opposite directions on the surface of the bidirectional lead screw 46, and the two driving blocks 47 are respectively screwed and installed on the two end thread lines.

[0036] Furthermore, avoiding holes are provided on the opposite surfaces of the two mounting frames 14. Driving lead screws 16 are rotatably installed in the two avoiding holes through bearings.

[0037] With the above structure, the non-threaded area of the surface of the driving lead screw 16 is fixedly installed on the inner ring of the bearing, and the outer ring of the bearing is fixed to the avoiding hole. The thread directions of the two driving lead screws 16 are opposite, ensuring that the two sliders 5 approach or move away simultaneously. The two third-stage gears and the two fourth-stage gears are symmetrically installed, facilitating the provision of power to the bidirectional lead screw 46.

[0038] Furthermore, limiting rods 22 are fixedly installed on the opposite surfaces of the two mounting frames 14. Sliders 5 are slidably installed on the surfaces of the two limiting rods 22.

[0041] By means of the above structure, the two positioning bolts 20 are rotated to move closer to each other, thereby squeezing and fixing the mounting knob 18, thereby limiting the rotation rod 17 and preventing it from rotating.

[0042] Working principle: When the device is in use, firstly, the two fixing blocks 23 are placed close to the lower side of the production line of galvanizing production and processing, and then the two mounting rings 40 are respectively placed between the two clamping blocks 25, and the mounting knob 18 is manually rotated, and the mounting knob 18 drives the rotating rod 17 to rotate, and the rotating rod 17 drives the two driving screws 16 to rotate, and the two driving screws 16 respectively drive the two sliders 5 to approach each other, and the two sliders 5 respectively drive the two bayonet ports 15 to approach each other, so that the two bayonet ports 15 are close to and installed on the support frame at the lower side of the production line, and at the same time, the driving screw 16 drives the three-stage bevel gear 44 to rotate when rotating, and the three-stage bevel gear 44 drives the four-stage bevel gear 45 to rotate, and the four-stage bevel gear 45 drives the bidirectional screw 46 to rotate, and the bidirectional screw 46 simultaneously drives the two driving blocks 47 to approach each other, and the two driving blocks 47 respectively drive the two clamping blocks 25 to approach each other through the two connecting rods 24, so that the two clamping blocks 25 are close to and fit on the limit ring 21, so that the clamping block 25 is fixedly connected with the mounting ring 40, and then the whole device is installed; When in use, first connect the air outlet of the blower to any one of the two primary air inlet pipes 2 or one secondary air inlet pipe 6 through a hose to seal the other two, or connect the two primary air inlet pipes 2 at the same time to seal the secondary air inlet pipe 6, or connect one secondary air inlet pipe 6 alone to seal the two primary air inlet pipes 2. Then rotate the pipe body 1 by hand, and the pipe body 1 drives the two primary air inlet pipes 2 to rotate. The two primary air inlet pipes 2 squeeze the positioning ball 42 through the positioning groove 43 on the surface, so that the positioning ball 42 is disengaged from the positioning groove 43 and guided to the next positioning groove 43. When aligned with the next positioning groove 43, the positioning ball 42 is pushed into the positioning groove 43 by the spring 41 to complete the repositioning, that is, complete the single angle adjustment. The angle adjustment can be completed by rotating the pipe body 1 to the specified angle as required, and then start the blower. The blower sends air into the pipe body 1 and blows it out through the wind tunnel 8 to evenly treat the surface coating of the galvanized sheet. When it is necessary to adjust the air flow, air pressure and air duct of the air knife, manually rotate the adjustment knob 13. The adjustment knob 13 drives the gear disk 10 to rotate. The gear disk 10 drives the first-stage gear 9 to rotate. The two first-stage gears 9 respectively drive the corresponding clamping blocks 39 to move. The clamping blocks 39 drive the connecting rod 24 to rotate. The connecting rod 24 drives the two second-stage bevel gears 38 to rotate. The two second-stage bevel gears 38 respectively drive the corresponding first-stage bevel gears 37 to rotate. The first-stage bevel gear 37 drives the adjusting screw rod 28 to rotate. The adjusting screw rod 28 drives the adjusting block 27 to move. The adjusting block 27 drives the adjusting plate 3 to move, making the adjusting plates 30 approach each other and reducing the distance between the two adjusting plates 30, thereby adjusting the air duct of the air knife. At the same time, when the two adjusting plates 3 approach each other, two of the adjusting blocks 27 respectively drive the corresponding third-stage connecting rods 34 to rotate through the extension blocks 36. The two third-stage connecting rods 34 drive the same second-stage connecting rod 33 to move away from the air plate 7. The second-stage connecting rod 33 drives a plurality of first-stage connecting rods 32 to move. The first-stage connecting rods 32 drive the corresponding connecting plates 31 to move. The connecting plates 31 drive the corresponding adjusting plates 30 to move, making the adjusting plates 30 slide on the surface of the stop block 29, increasing the diameter of the air hole 8, increasing the gas flow rate, and increasing the air flow and air pressure of the air knife.
