Description

Technical Field

[0001] The utility model relates to the technical field of polymer spraying, in particular to a protective cover for polymer spraying equipment. Background Art

[0002] Polymer spraying is a process of spraying polymer materials on the surface of workpieces to achieve protection, decoration or functional improvement. Polymer spraying usually uses polymer coatings, such as polyurethane, epoxy resin, acrylate, etc. These materials have excellent wear resistance, corrosion resistance, chemical resistance and other properties. Polymer spraying equipment is used during polymer spraying. In order to protect the operator from the spray particles, solvent gases and other harmful substances generated during the spraying process, most polymer spraying equipment in the prior art generally installs a protective cover at the nozzle.

In the prior art, most of the protective covers of the polymer spraying equipment are not convenient to clean during the spraying process and the spraying work needs to be stopped before cleaning, which greatly affects the normal progress of the work and reduces the efficiency of the spraying work. Therefore, it is necessary to design a protective cover for the polymer spraying equipment that can clean the protective cover while the spraying work is in progress. Utility Model Content
