Description

Technical Field

[0001] The utility model relates to the technical field of metal valve processing, in particular to a spraying device for anti-corrosion processing of metal valves. Background Art

[0002] As is known to all, the anti-rust paint spraying device for metal valve and pipe fittings processing is a device used to spray special anti-rust paint on the surface of the valve and pipe fittings after processing and forming, so as to reduce or isolate the contact between the humid air in the outside air and the valve and pipe fittings, thereby preventing or delaying the formation of rust on the surface of the valve and pipe fittings, so as to improve the production life of the processed metal valve and pipe fittings. It has been widely used in the field of metal valve and pipe fittings processing.

[0003] The currently published patent: CN220346302U discloses a valve paint spraying equipment for valve production. The spraying equipment places the valve on a placement table, and the driving motor drives the placement table to rotate. The paint pump pumps the paint in the paint box through the paint pipe to the air outlet of the stand, thereby spraying the rotating valve. After spraying, the dryer supplies air to the air outlet of the stand through the air supply pipe, which can dry the rotating valve. The setting of the protective structure can prevent paint from splashing, and the odor gas can be filtered through the filter box and the exhaust fan, which increases the practicality of the structure. The spraying and drying of the structure are integrated structures, and it can be dried in time after spraying to prevent the paint from flowing and causing uneven paint surface.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: when the spraying equipment is in use, it can be dried in time after spraying to prevent the paint from flowing and causing an uneven paint surface, but this spraying method can only spray one valve component at a time. After the valve component is sprayed, it must be taken out and the next valve component can be sprayed. The valve components cannot be sprayed continuously, the spraying efficiency is low, and it is not suitable for large-scale valve spraying processing. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a spraying device for anti-corrosion processing of metal valves, which can solve the problem that the valve parts cannot be sprayed continuously until they are taken out after spraying, the spraying efficiency is low, and it is not suitable for large-scale valve spraying processing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spraying device for anti-corrosion processing of metal valves, comprising a spraying box, the surface of which is provided with two square openings, a partition fixedly connected inside the spraying box, a rotating rod rotatably connected inside the partition, a large pulley fixedly connected at the lower end of the rotating rod, a belt drivingly connected on the surface of the large pulley, and a spraying device arranged at the upper end of the rotating rod;

[0007] The spraying device comprises a turntable which is welded to the upper end of a rotating rod. Six circular grooves are arranged on the top of the turntable. The insides of the six circular grooves are all rotatably connected with a rotating base for spraying.

[0012] Preferably, a hot air blower is fixedly mounted on the top of the spray box, and a conical spray barrel is fixedly mounted on the air outlet of the hot air blower.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) In the spraying equipment for anti-corrosion processing of metal valves, the gears rotate and drive the rotating base and valve parts to rotate through the rotating shaft, thereby improving the uniformity of spraying on the surface of the valve parts. The valve parts that have been sprayed gradually move and eventually move out of the interior of the spraying box through the square opening on the right. This spraying method can continuously spray the valve parts through the rotation of the turntable, thereby increasing the spraying efficiency of the valve parts.
