Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, and in particular to a metal rust remover spraying device. Background Art

[0002] Metal rust remover is a special liquid mixture that can remove rust and dissolve metal oxides without corroding metal materials. For most metal products, their surfaces are easily oxidized by oxygen in the air and rusted by water vapor. In order to extend the service life of metal products, it is generally necessary to use a spraying device to remove rust from metal products.

[0003] Existing paint spraying devices generally use manual rust removal and paint spraying, which wastes a lot of manpower and material resources, increases the labor intensity of the staff, and reduces work efficiency. After the rust removal and paint spraying device is used, some paint will remain on the nozzle. If the nozzle is not treated, due to the high internal air pressure, the nozzle will continue to drip residual paint, polluting the environment.

[0004] In view of this, research and improvements are conducted on the existing problems, and a metal rust remover spraying device is provided to solve the problem of low work efficiency of manual rust removal and spraying in the prior art, as well as the problem that the paint remaining on the nozzle of the rust removal and spraying device in the prior art will pollute the environment after use. The purpose is to achieve the purpose of solving the problems and improving the practical value through this technology. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a metal rust remover spraying device is proposed. The present invention realizes automatic clamping of pipe fittings through an air pump and an air cylinder to adapt to pipe fittings of different lengths. The motor drives the screw rod to move the paint spray box up and down to achieve uniform paint spraying. The air pressure controls the exposure and hiding of the nozzle to prevent paint dripping pollution. The transmission mechanism synchronously rotates the carrier plate to ensure comprehensive paint spraying and improve the spraying effect.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a metal rust remover spraying device comprises a box body, an air pump is fixedly installed on the top of the box body, an air cylinder connected with the air pump is installed on the top of the inner side of the box body, a sliding rod is slidably connected inside the air cylinder, and a clamping mechanism is arranged at the bottom end of the sliding rod, the clamping mechanism comprises a shell, a guide rod is slidably connected inside the shell, the bottom end of the guide rod passing through the outside of the shell body is fixedly connected with a carrier plate, a screw rod is rotatably connected inside the box body, a motor is fixedly installed on the top of the screw rod, a paint spray box is threadedly connected to the outer wall of the screw rod, a sleeve is fixedly installed inside the paint spray box, a piston is slidably connected inside the sleeve, a moving rod is fixedly connected to one side of the piston, a slide rail is fixedly connected to one side of the paint spray box, a baffle is slidably connected to the outer wall of the slide rail, the outer wall of the moving rod is rotatably connected to the bottom of the baffle through a linkage rod, the outer wall of the paint spray box passes through a fixedly connected nozzle, and a nozzle is fixedly connected to one end of the nozzle.

The baffle moves downward to allow the nozzle to leak out, making it easier to spray paint. When the painting is completed, the air pressure inside the paint spray box decreases, and the elastic potential energy of the return spring in the slide rail is used to drive the baffle to move in the opposite direction, causing the baffle to move upward to block the nozzle to prevent paint dripping and polluting the environment. When the screw rotates, it simultaneously drives the transmission mechanism to move, causing the transmission mechanism to drive the carrier plate to rotate synchronously, thereby facilitating uniform painting of the pipe fittings, avoiding the problem of incomplete painting, and improving the effect of painting.
