Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a non-woven wallpaper coating machine. Background Art

[0002] Non-woven wallpaper is a basic material made using a special non-woven process. This material has good air permeability, moisture resistance and environmental protection properties. The non-woven wallpaper coating machine is a device specially used for the production of non-woven wallpaper.

[0003] The die head on the coating machine is set close to the coating roller. In order to facilitate the threading and installation of the non-woven wallpaper through the gap between the coating roller and the die head, the die head is usually set to a form that can slide and adjust the space. In addition, in order to implement stable sliding positioning of the die head, the die head is usually equipped with two positioning components.

[0004] Most existing coating machines lack a mechanism that can drive the two positioning components to loosen and tighten synchronously, resulting in the need to loosen and tighten the two positioning components step by step when positioning and loosening the die head. This is more troublesome to operate and indirectly reduces the sliding adjustment efficiency of the die head. Utility Model Content

[0024] Further,

[0025] The rectangular mounting frame is welded between the top ends of the two vertical support plates located on the coating roller side, and the rectangular mounting frame protrudes from the two vertical support plates;

[0026] The die head is arranged close to the coating roller and is used for extruding and coating the coating on the non-woven wallpaper passing through the coating roller.

[0027] The non-woven wallpaper coating machine provided by the utility model has the following beneficial effects:

[0028] 1. Through two shaft sleeves, the die head can slide along two longitudinal support positioning shafts away from the coating roller to expand the threading gap between the head end of the die head and the coating roller, making it easier to thread and install the non-woven wallpaper.
