[0045] The stainless steel mesh chain conveyor device 2 is mainly composed of a stainless steel mesh chain 4, a conveyor track 5, a center positioning rod 7, and a movable adjustable positioning rod 8;

[0046] The stainless steel mesh chain 4 is automatically conveyed through the conveyor track 5, and a hollow support frame 6 is arranged around the stainless steel mesh chain 4 to fix the center positioning rod 7 and the movable adjustable positioning rod 8;

[0049] The periphery of the noise prevention device 9 is wrapped with sound insulation cotton, and it is entirely covered above the stainless steel mesh chain conveyor device 2. Its function is to block wind shear noise, reduce noise damage to employees, and improve employee comfort; multiple maintenance windows 10 are opened around it for subsequent maintenance;

[0051] The left and right wind shear movable positioning rods 13 and the upper and lower wind shear movable positioning rods 15 enable the wind shear device to be adjustable up and down, left and right, and front and back;

[0052] Above the stainless steel mesh chain conveyor device 2, multiple wind shear devices 3 are fixed on the movable adjustable positioning rods 8, and the left and right, up and down, and front and back dimensions of the wind shear device can be freely adjusted to meet the needs of different products. This device is responsible for shearing the water stains on the upper part of the product from top to bottom; multiple wind shear devices are also equipped at the hollow part below the stainless steel mesh chain conveyor device 2 and fixed on the positioning rods at the lower part, so that the lower part of the cleaning jig can also be sheared and blown obliquely from bottom to top to ensure that the lower part of the cleaning jig is effectively wind sheared to achieve the function of blowing off water stains;

[0054] The center of the wind shear emitter is connected with an air pipe to evenly and quickly disperse the air pressure to the wind shear emitter head. The wind shear emitter head is designed to simulate a wind gun head, so that the wind gun does not blow vertically on the product, but blows on the product at multiple angles to achieve the effect of blowing off the water stains on the product;

[0055] One wind curtain 11 is installed in front of and behind each two wind shear automation devices 3. The addition of the wind curtain 11 simulates multiple airflow concentration areas, which can effectively concentrate the airflow inside the device, obtain an efficient wind shear working cycle, and improve the water stain blowing effect on the product surface by 60%;

[0056] Further, the working surface of the workbench frame 1 is recessed to support the stainless steel mesh belt conveying device 2 for effective transmission.

[0058] The movable adjustable positioning rod 8 can adjust the flow width according to the size of the cleaning fixture to adapt to any size fixture and meet the fixture requirements of different products;

[0060] Further, the air knife automation device 3 can be placed below the stainless steel mesh belt conveying device 2 so that the lower part of the product of the cleaning fixture can also be effectively air-knifed, and the air knife effect is improved by more than 50%.

[0061] Further, for the air knife emitter, the design principle is to evolve multiple traditional air guns into air knife emitters.

[0063] The air knife emitter is centrally connected to an air pipe to evenly and quickly disperse the air pressure to the air knife head. The air knife head is designed to simulate an air gun head, so that the air gun does not blow vertically on the product, but blows on the product at multiple angles to achieve the effect of blowing off the water stains on the product;

[0064] The air knife automation device 3 connected to the outer end air pipe automatically blows air obliquely up and down at multiple angles on the product, and blows off the residual water stains on the product surface under heavy load; the air knife automation device 3 is arranged in a left-right cross pattern within the entire noise-proof device 9 and can adjust the air knife position in multiple directions including left-right, up-down, and front-back to meet the air knife requirements of various products;

[0066] Furthermore, for the air curtain 11, multiple air curtains 11 are evenly distributed above the stainless steel mesh belt conveying device 2. The design principle is to divide the air knife automation device 3 into multiple independent working centers. A single independent working center can effectively concentrate the airflow inside the device, obtaining an efficient air knife working cycle, and improving the effect of blowing off the water stains on the product surface by 60%. The multiple air curtains 11 equipped inside the air knife automation device 3 simulate multiple airflow concentration areas, which can effectively concentrate the airflow inside the device, obtaining an efficient air knife working cycle and blowing off the water stains on the product surface.

[0068] The utility model innovatively adds an air knife system above and below the stainless steel mesh belt conveying device 2. The cleaning fixture automatically rotates through the conveyor belt. The air knife systems above and below it automatically blow air at multiple angles obliquely onto the products on the cleaning fixture through externally adjustable air pressure, thereby achieving the effect of automatically blowing off the residual water stains on the product surface and avoiding appearance defects caused by the residual water stains on the product after cleaning. Moreover, the air knife head is designed with an oblique cutting angle to avoid the product being blown off and scrapped due to vertical air knife cutting; multiple air outlets are equipped to ensure that every part of the product can be air-knifed in all directions and the water stains on the product surface are blown off.

[0069] Operating principle: The employee places the cleaning fixture filled with products on the stainless steel mesh belt conveying device 2. The movable adjustable positioning rod 8 adjusts the lateral limit of the cleaning fixture, and the center positioning rod 7 distinguishes the cleaning fixtures on the left and right sides to prevent the two fixtures from colliding with each other and causing product damage; the air knife automation device 3 connected to the outer end air pipe automatically blows air at multiple dimensions and angles obliquely onto the products, and blows off the residual water stains on the product surface with a large load.

[0070] The air knife automation device 3 is arranged in a left-right cross pattern inside the entire noise prevention device 9, and can adjust the air knife position in multiple directions of left-right, up-down, and front-back to meet the air knife requirements of various products.

[0071] The air knife automation device 3 is equipped with multiple air curtains 11, which simulate multiple airflow concentration areas, can effectively concentrate the airflow inside the device, obtain an efficient air knife working cycle, and improve the effect of blowing off the water stains on the product surface by 60%.
