Description

Technical Field

[0001] This utility model relates to the field of sealing strip coating technology, specifically to a device for applying primer to rubber sealing strips. Background Technology

[0002] Automotive sealing strips serve to fill various gaps and joints between vehicle body components, providing functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration. They enhance the comfort of the driving experience and protect the vehicle body, making them indispensable. Automotive sealing strips primarily prevent the leakage of air, liquids, and other substances, improving the stability of the in-vehicle environment, reducing noise, and increasing ride comfort. They also provide some sound insulation, enhancing the driving experience. Furthermore, they prevent external dust and dirt from entering the vehicle, keeping the interior clean. Currently, sealing strips are typically applied by using a caulking gun to coat them with adhesive before installation.

[0003] A spraying device for processing automotive rubber sealing strips, disclosed in CN215030347U, relates to the field of spraying devices. Addressing the problem that current spraying devices used in automotive sealing strip production cannot simultaneously spray the sealing strips, resulting in an overly cumbersome and time-consuming spraying process, the following solution is proposed: It includes a spraying box with material bins spaced apart at the top. A transport pipe is installed at the bottom of each material bin, extending through the spraying box into its interior. Sprayers are evenly distributed on one side of the transport pipe. A sealing strip body is located on one side of the spraying box, extending through the spraying box into its interior, and the sealing strip body is matched with the sprayers. A steering rod is installed inside the spraying box, and the steering rod is matched with the sealing strip body. This spraying device for processing automotive rubber sealing strips can perform omnidirectional spraying of the sealing strip body by combining the steering rod and the sprayers.

[0004] The above-mentioned equipment also has some problems in use: it is impossible to clean the surface of the sealing strip before applying glue, and it is impossible to remove dust and impurities from the surface of the sealing strip. As a result, the dust and impurities attached to the surface of the sealing strip will affect the glue application effect. Furthermore, after the glue is applied, there may be uneven glue thickness, resulting in an uneven surface of the sealing strip, which will affect the quality of the products after production.
