technical field

The utility model relates to the technical field of coating, in particular to a coating machine.

Background technique

The coating machine is a device that coats a roll of substrate with a layer of glue, paint or ink with a specific function, and then winds it up after drying. It is mainly used for the production of surface coating processes such as films and paper. In industrial production, the glued layer after the base material is glued sometimes needs to be pressed into a composite material with another base material, and the composite material is dried and rolled after the pressing is completed. Most of the drying mechanisms of existing coating machines adopt the form of hot air drying. During the hot air drying process, the wind blown from the air nozzle is blown vertically or obliquely to the coated substrate. This drying method has the following disadvantages: The wind direction and air volume of the nozzle cannot be adjusted, which makes the drying process inflexible. Facing substrates with different glue thicknesses, the drying can only be achieved by adjusting the wind strength and wind temperature. When it is sensitive, a good drying effect cannot be obtained; during the hot air drying process, the wind force blows the substrate away from the operating plane of the coating drying tunnel or skews the substrate, resulting in poor drying effect and inconvenient winding.

Therefore, how to provide a coating machine that can flexibly adjust the air supply angle and air volume of the drying mechanism of the coating machine, and give flexible pull-down force to the substrate on the drying tunnel, so that the substrate will not be blown under the action of wind force. It is a problem to be solved urgently by those skilled in the art to prevent the lifting and outward tilting phenomenon and ensure the drying effect and winding effect.
