Aiming at the problem that the spraying device used in the current production of automobile sealing strips cannot spray the sealing strips simultaneously, resulting in a too troublesome and time-consuming spraying process, the following scheme is proposed. It includes a spraying box, and material boxes are arranged at intervals on the top of the spraying box. A transportation pipe is installed at the bottom of the material box, and the transportation pipe penetrates through the spraying box and extends into its interior. Sprayers are evenly distributed on one side of the transportation pipe. A sealing strip body is arranged on one side of the spraying box, and the sealing strip body penetrates through the spraying box and extends into its interior, and the sealing strip body is matched with the sprayers. A steering rod is arranged inside the spraying box, and the steering rod is matched with the sealing strip body. The spraying device for processing automobile rubber sealing strips can spray the sealing strip body comprehensively through the combination of the steering rod and the sprayers.
