[0002] The air knife is a tool for drying and chip removal with the help of compressed air, which is widely used in the industrial field; the photovoltaic ribbon is made of copper wire after a series of processes such as drawing, calendering, annealing and tin coating After the copper wire is tinned, it is usually necessary to use an air knife to dry the tin liquid coated on the surface of the copper wire. Dry tin liquid, resulting in poor drying effect; in addition, because the tin liquid will inevitably produce tin dust during the process of being blown dry, and the generated tin dust will continue to adhere to the air knife, which will affect the air quality in the long run. The air knife works, so it must be manually cleaned regularly, so it is time-consuming and laborious, and it is urgent to wait for a solution

The invention relates to a composite air knife device. The device comprises a bottom block, a top block detachably fixed to the top of the bottom block and a stop block detachably embedded and fixed to the bottom of the bottom block, wherein a first sinking cavity is formed in the center of the bottom of the top block, a conical head is downwards formed in the center of the bottom face of the first sinking cavity, and correspondingly, a first conical sinking cavity is formed in the center of the top of the top block. By means of a conical annular gap formed between the outer wall of the end of the conical head and the inner wall of a second conical sinking cavity, the blow-drying speed is greatly increased, so that the production efficiency is improved, tin liquid can be blow-dried in all directions, and the blow-drying effect is remarkably improved; and in addition, annular airflow can be formed by means of a gap between the bottom edge of the conical surface and the edge of an opening of the second sinking cavity, then tin ash generated in the blow-drying process is automatically removed so as to be prevented from being attached to an air knife, it can be guaranteed that the air knife works effectively for a long time without regular manual cleaning, and the time-saving and labor-saving effects are achieved.
