[0001] The utility model relates to the technical field of spray coating, in particular to a hydraulic drive mechanism for a coating surface production line. Background Art

[0002] After the workpiece is manufactured, it needs to be surface sprayed according to its use environment. For example, a corrosion-resistant coating is sprayed on the surface of the workpiece to increase the corrosion resistance of the workpiece. When the height of the workpiece to be sprayed exceeds the spray range of the nozzle, multiple nozzles need to be set within the height range for joint spraying. Spraying in this way is prone to repeated spraying or missed spraying at the junction of the coatings sprayed by two nozzles, resulting in uneven spray thickness and affecting product quality.

[0003] For example, CN201210104358.X discloses an online spraying device for special-shaped steel, which is used for online spraying of rust inhibitor on special-shaped steel, and comprises: a rust inhibitor tank, used for storing the rust inhibitor; a hydraulic pump, used for delivering the rust inhibitor to the rust inhibitor delivery pipeline; a first bracket and a second bracket, which are arranged on the left and right sides of the special-shaped steel and are respectively provided with at least one slide groove; a plurality of nozzles, which are slidably arranged in the slide grooves of the first bracket and the second bracket through connecting parts, and are arranged around the special-shaped steel.

[0004] The online spraying device for special-shaped steel is provided with a plurality of nozzles around the special-shaped steel, and a plurality of nozzles are provided on each surface of the special-shaped steel. When the special-shaped steel is sprayed by the plurality of nozzles, repeated spraying or missed spraying may easily occur at the junction of the nozzle spraying, thereby causing uneven spraying thickness and affecting product quality.
