Technical Field

[0001] The present application relates to the technical field of spraying machines, and in particular to a cleaning mechanism and a gearbox cover spraying machine. Background Art

[0002] The surface of the gearbox cover needs to be sprayed with a layer of protective paint. Usually, a mechanical arm is used to carry a spray gun to spray the gearbox cover according to a predetermined trajectory. Different specifications of gearbox covers require different protective paints, so the channels in the spray gun need to be cleaned before changing the paint. The cleaning process is slow and affects production efficiency. Utility Model Content

[0003] In order to make up for the above deficiencies, the present application provides a cleaning mechanism and a gearbox cover sprayer, aiming to improve the problems mentioned in the above background technology.

[0004] In the first aspect, an embodiment of the present application provides a cleaning mechanism, including a spray gun body and a feed pipe, the spray gun body is provided with a feed port and a stud, the feed port is provided with a switching component, a water supply component is threaded on the stud, and the water supply component and the feed pipe are connected to the feed port through the switching component.

[0005] In a specific embodiment, the switching member includes a valve block, and the valve block is provided with two channels identical to the spray gun body, and the two channels are respectively connected to the water supply member and the feed pipe.

[0006] In a specific implementation manner, a valve core is rotatably connected to the valve block, and two through holes are provided on the valve core, respectively located on two channels. The two through holes are perpendicular to each other, and sealing rings are provided on both sides of the channels.

[0007] In the above implementation process, the two through holes are switched to align with the two channels respectively by rotating the valve core 90 degrees, thereby connecting the two channels respectively. The sealing ring is used to improve the sealing performance of the valve core and the valve block, and can also improve the damping between the valve core and the valve block.

[0008] In a specific implementation manner, a limiting ring is fixedly connected to the valve core, a pressure cover is screwed on the valve block, and the pressure cover limits the limiting ring on the valve block.

[0009] In the above implementation process, the gland is tightened on the valve block, and the limit ring can rotate but cannot move axially, so it plays the role of installing the valve core. The valve core can also be pulled out to facilitate cleaning the inside of the valve block.

[0010] In a specific implementation manner, the outer end of the valve core is fixedly connected with a shift rod.

[0011] In the above implementation process, the lever is convenient for manual dialing and indicating the conduction of the channel, and can also restrict the pressure cover between the limit ring and the lever, so that the pressure cover is not easily lost after the valve core is pulled out.

[0012] In a specific embodiment, the water supply component includes a water tank, the water tank is threadedly connected to the stud, and the water tank tightens the valve block onto the stud.

[0013] In a specific embodiment, a water pipe is provided on the water tank and is connected to the corresponding channel.

[0014] In the above implementation process, there is cleaning fluid in the water tank. During cleaning, the water tank and the spray gun body are connected by a switching member, so that the cleaning fluid will enter the spray gun body instead of the paint to clean the inside of the spray gun body. In this embodiment, the water tank also acts as a fastener during the screw connection process to fix the valve block on the spray gun body, thereby improving the installation strength of the valve block. The water tank and the valve block can also be removed to form an ordinary spray gun body. This design facilitates the modification of a conventional spray gun body and helps reduce the modification cost.

[0015] In a second aspect, the present application further provides a transmission cover spray machine, comprising the above-mentioned cleaning mechanism.

[0016] Compared with the prior art, the beneficial effects of the present application are: the water supply component and the feed pipe are switched to be connected to the spray gun body by using a switching component, so as to quickly switch between painting and cleaning, and the water from the water supply component replaces the paint to enter the spray gun body and be sprayed out, thereby effectively cleaning the inside of the spray gun body, further improving the cleaning efficiency, and improving the spray machine changeover efficiency.
