Description

[Technical field]

[0001] The utility model belongs to the technical field of spraying equipment, in particular to a self-cleaning material blocking mechanism used in a spraying machine. [Background technology]

[0002] A sprayer is a device used to spray coatings, paints or other coating materials evenly onto various surfaces. It is widely used in the construction, automobile, furniture, shipbuilding, aerospace and other industries. However, some products do not need to be sprayed with coatings at the installation and connection parts. Therefore, existing sprayers set a baffle plate above the product to block the coating from being sprayed onto the parts of the product that do not need to be sprayed. However, during the spraying process, the coating will accumulate on the baffle plate. If it is not handled for a long time, a certain amount of the accumulated coating will drip onto the product below, affecting the product quality. [Utility Model Content]
