Description

Technical Field

[0001] The invention relates to the technical field of parts processing, and in particular to a paint spraying rack with an exhaust gas treatment function. Background Art

[0002] When finely processing metal plates or metal products, the overall process includes surface cleaning, surface degreasing, surface base electroplating primer, surface topcoat spraying, and oven drying after the plates are put into storage. When spraying metal parts, in order to improve the overall spraying effect of metal parts, it is often necessary to use external spraying hangers to hang metal parts, and then cooperate with spraying equipment to spray paint the surface. However, there are still some problems when using existing spraying hangers:

[0003] 1. Uneven painting effect. When hanging metal parts that need to be processed, the existing paint hangers cannot rotate after hanging. Therefore, when spraying the paint on the side, the paint surface on the back far away from the spray head often has uneven adhesion, which affects the overall painting effect.

[0004] 2. It is easy to generate waste gas. When the existing spray paint hangers hang metal parts for spray painting, the splashed paint particles will float in the air, and the air will be polluted by the paint. The traditional way is to directly discharge it into the atmosphere, which will cause the surrounding air to be polluted and produce unnecessary polluted waste gas. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a paint spraying rack with exhaust gas treatment function.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A paint spray rack with an exhaust gas treatment function, comprising a paint spray treatment box and a servo motor, wherein a hollow column tube is rotatably mounted on the inner wall of one side of the top of the paint spray treatment box, and the hollow column tube is located on the outer wall of the paint spray treatment box and is connected to connecting pipes distributed at equal distances, and the end of the connecting pipe is connected to a hanging pillar, and the inner walls around the hanging pillar are connected to supporting air bags distributed at equal distances, a rotating shaft rod is welded to the inner wall of the hanging pillar, and the bottom of the rotating shaft rod is inserted into the bottom of the connecting pipe, and a driving gear is welded to the outer wall of the bottom of the rotating shaft rod;

[0008] A driving rack is meshed on one side of the driving gear, and an electric telescopic rod is fixed to the outer wall of the same side of the driving rack by screws, a first atomizing nozzle is arranged on the inner wall of one side of the paint spraying treatment box, and a feed pipe is installed on the inner wall of the first atomizing nozzle, an air intake pipe is connected to one side of the bottom of the paint spraying treatment box, and the end of the air intake pipe is connected to a purification box, second atomizing nozzles are installed on the inner walls of both sides of the purification box, and a drain pipe is connected to the inner wall of one side of the bottom of the purification box, a ventilation pipe is connected to the inner wall of one side of the purification box, and the end of the ventilation pipe is connected to a cylindrical shell, and an exhaust pipe is arranged between the cylindrical shell and the paint spraying treatment box.

[0009] As a further solution of the present invention: a rectangular installation groove is provided on an inner wall of one side of the paint spraying treatment box, and a sealed box door is hinged on the inner wall of the rectangular installation groove, and a handle is welded on the outer wall of the sealed box door.

[0010] As a further solution of the present invention: an inner wall on one side of the top of the hollow column tube is connected to an inflation tube, and an air valve core is installed on the inner wall of the inflation tube.

[0011] As a further solution of the present invention: a first bevel gear is welded at the axis center of the top of the hollow column tube, and a second bevel gear is meshed along a vertical side of the top of the first bevel gear, and a servo motor is connected to the axis center of one side of the second bevel gear.

[0012] As a further solution of the present invention: the top outer wall of the purification box is penetrated with water curtain grooves distributed at equal distances, and a water storage tank is welded to the top outer wall of the purification box, and the water storage tank is filled with purified filtrate.

[0013] As a further solution of the present invention: a cylindrical filter box is installed on the inner wall of the cylindrical shell, and an exhaust fan is installed at the axis of the cylindrical filter box.

[0014] As a further solution of the present invention: the cylindrical filter box is a mesh structure, and the interior of the cylindrical filter box is filled with activated carbon.

[0015] As a further solution of the present invention: the electric telescopic rod, the servo motor and the exhaust fan are all connected to a PLC controller via signal lines, and the PLC controller is connected to an external power supply via wires.

[0016] Compared with the prior art, the present invention provides a spray paint rack with exhaust gas treatment function, which has the following beneficial effects:

[0017] 1. The paint spraying hanger of this design hangs the metal parts to be processed on the hanging pillar, and first uses the servo motor to drive the hollow column tube to rotate, so as to drive the metal parts to rotate. During the rotation process, when spraying paint, the driving rack is used to drive the driving gear to rotate, so as to drive the metal parts to rotate, so as to make the paint spraying more uniform and improve the painting effect.

[0018] 2. After the metal parts are hung and placed, the paint hanger designed in this way uses support airbags to fill the gap between the parts and the hanging pillars to improve the overall stability and avoid unnecessary shaking during rotation. This not only makes the contact surface soft, but also can assist in fixation.

[0019] 3. The paint spraying rack of this design, when treating the exhaust gas generated during the painting process, first passes the exhaust gas through multiple layers of water curtains and is sprayed with the help of an atomizing nozzle, so that the paint particles in the air can be purified, and the purified air passes through the filter box containing activated carbon again, so that the exhaust gas can be purified by a variety of purification methods.

[0020] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
