Embodiment Construction
[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0018] A circular air knife for high concentricity, such as Figure 1-2 As shown, it includes an upper shell 1 and a lower shell 2. A mold hole passing through the welding strip is set at the center of the upper shell 1 and the lower shell 2. After the upper shell 1 and the lower shell 2 are closed, a gas flow is formed. The cavity, and the mold holes of the upper shell 1 and the lower shell 2 form a blowing port 3, and the cavity includes a horizontal section 4, a vertical section 5 and an oblique section 6; wherein, the horizontal section 4 and the vertical section 5 are mutually Cooperate to av...

The invention discloses a circular air knifefor high concentricity. The circular air knife comprises an upper shell and a lower shell, mold holes for a welding strip to penetrate through are formed in the circle centers of the upper shell and the lower shell, a cavity for air circulation is formed after the upper shell and the lower shell are closed in a covering mode, and air blowing openings are formed in the mold holes of the upper shell and the lower shell. The cavity comprises a horizontal section, a vertical section and an inclined section; at least two air inlets connected with the horizontal section are equally formed in the side wall of the lower shell; a first flow stabilizing plate and a second flow stabilizing plate are arranged in the vertical section; and a plurality of flow stabilizing holes are formed in the first flow stabilizing plate and the second flow stabilizing plate. The horizontal section and the vertical section are arranged, the situation that airflow directly blows and impacts through the corners, consequently, airflow in part of positions is too large is avoided, and airflow stability is improved. The first flow stabilizing plate and the second flow stabilizing plate are arranged for secondary steady flow, and the silica gel layer is attached to the upper surface of the first flow stabilizing plate, so that the pressure of airflow passing through the first flow stabilizing plate is uniform; and the manufacturing cost is reduced through the opening of the silica gel layer.
Description
technical field [0001] The invention relates to the field of welding strip production, in particular to a circular air knife for high concentricity. Background technique [0002] At present, after the soldering strip is coated with tin, there will be excess tin liquid on the surface of the soldering strip, and the excess tin on the surface of the soldering strip needs to be blown off; Chinese patent CN 208532912 U is a circular air knife, in which only one In the air inlet pipe, the air flow is very unstable; in addition, a silicone valve is set on the partition to make the pressure of the gas discharged from the air outlet chamber uniform. Good for mass promotion. Contents of the invention [0003] Aiming at the defects of the above prior art, the main purpose of the present invention is to overcome the deficiencies of the prior art, and discloses a circular air knife for high concentricity, including an upper shell and a lower shell, the The center of the upper shell a...
