Description

Technical Field

[0001] The utility model relates to the technical field of coating machine cleaning equipment, in particular to a nozzle cleaning device for a coating machine. Background Art

[0002] Coating machines are mainly used for surface coating production of films, paper, etc. It can coat the rolled substrate with a layer of glue, paint or ink with specific functions, and cut it into sheets or roll it up after drying. The coating machine uses a special multi-functional coating head, which can realize various forms of surface coating. In the coating machine, the nozzle is a key component, which is often used to spray glue or other coatings. Its function is to spray glue or coating evenly on the surface of the object to be coated. During the coating process, the nozzle is often blocked or unevenly sprayed due to paint residue, impurity accumulation, etc., which affects the coating quality and production efficiency. Therefore, cleaning the nozzle is an important task in coating machine maintenance.

[0003] In recent years, although some automated nozzle cleaning equipment has appeared, most of the equipment has a single cleaning method, such as high-pressure water flushing or solvent immersion, which cannot thoroughly clean the inside of the nozzle. Moreover, some equipment cannot effectively fix and protect the nozzle during the cleaning process, which can easily cause damage to the nozzle. For this reason, we propose a nozzle cleaning device for a coating machine. Utility Model Content

[0029] Furthermore, the clamping device 4 also includes a drive motor 10, a gear 11, a double-headed threaded rod 13 and a gear 2 14. The side of the mounting block 8 is fixedly connected to the outer end of the cleaning tank 1 corresponding to the drive motor 10, and the rotating shaft of the drive motor 10 extends to the inner cavity of the mounting block 8 and is fixedly connected to the gear 11.

The two ends of the double-headed threaded rod 13 have opposite thread directions, which are respectively connected to the two clamping plates 16, so that they can move toward or away from each other, thereby driving the two clamping plates 16 to move toward each other. The clamping plate 16 is made of soft rubber and has triangular grooves on its surface to provide better clamping force and anti-slip effect until the nozzle is firmly clamped. The supply valve of the cleaning agent or water is opened to spray the liquid onto the nozzle through the high-pressure spray pipe 3. At the same time, the handle 6 can be manually operated or driven by the drive motor 10 to make the annular rotating block 9 drive the nozzle to rotate in the cleaning tank 1 to ensure that the cleaning agent can fully cover all parts of the nozzle.
