[0002] Coating is a crucial step in surface manufacturing processes, and coating equipment is a vital component of the entire coating process. It is used to apply coatings to the surface of workpieces. However, existing coating equipment still has certain shortcomings, such as:

[0003] The application CN202421085567.9, entitled "An Energy-Saving Coating Equipment", does not have the function of waste gas recovery during use. Because irritating gases are volatilized into the air during the coating process, forming waste gas, it will cause air pollution and endanger the health of workers, thus limiting its use. In view of this, a coating equipment with a waste gas recovery structure is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a coating equipment with a waste gas recovery structure to solve the problem mentioned in the background art that existing coating equipment cannot recover waste gas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating equipment with a waste gas recovery structure, comprising a base, an air suction cylinder, and a material bin fixedly installed on the top surface of the base.

The outlet end of the material pump is fixedly connected to one end of the material conveying hose, and the other end of the material conveying hose is fixedly connected to the nozzle.

[0010] The above technical solution facilitates the delivery of the coating through the nozzle.

[0011] As a preferred embodiment of this utility model, a fixing frame is fixedly installed on the top surface of the base, and a first motor is fixedly installed on the top surface of the fixing frame. The shaft end of the first motor is keyed to a lead screw, and the lead screw is fixedly installed on the top of the fixing frame.

[0020] The above technical solution facilitates the rotation of the rotating rod, which in turn drives the square rod to rotate, thereby driving the hollow tube to rotate. This, in turn, drives the mounting shaft and fan blades to rotate via the bevel gear set, ensuring the effective intake of exhaust gas.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the coating equipment with waste gas recovery structure can ensure effective coating of workpieces, and at the same time effectively collect the waste gas generated during the coating process, and transport it to the external air purification equipment for treatment through the exhaust hose, thereby avoiding the direct volatilization of irritating gases into the air, greatly reducing air pollution, effectively protecting the health of workers, solving the problem of waste gas emissions from traditional coating equipment harming the environment and human health, and is simple and flexible to operate and highly practical.

[0022] 1. The paint is drawn through the extraction pipe by the extraction pump and delivered to the nozzle through the delivery hose, thereby achieving the coating of the workpiece;

[0024] 3. The second motor drives the rotating shaft to rotate, which in turn drives the worktable to rotate, thereby causing the workpiece on the top of the worktable to rotate synchronously, thus ensuring comprehensive, effective and uniform coating of the workpiece and improving the coating effect.

[0025] 4. When the shaft rotates, the drive pulley and belt, along with the driven pulley, drive the rotating rod to rotate, which in turn drives the square rod to rotate synchronously. This causes the square rod to drive the hollow tube to rotate, which in turn drives the mounting shaft and fan blades to rotate through the bevel gear set. This ensures that the exhaust gas is effectively drawn into the suction cylinder and discharged to the external air purification equipment through the exhaust pipe, thus achieving the recycling and treatment of the exhaust gas.

[0026] 5. The L-shaped connecting rod ensures that the suction cylinder moves synchronously with the slider, ensuring that the suction cylinder is always in the optimal suction position and effectively collecting exhaust gas. Attached Figure Description

[0036] A mounting bracket 13 is fixedly installed on the top surface of the base 1, and a first motor 14 is fixedly installed on the top surface of the mounting bracket 13. The shaft end of the first motor 14 is keyed to a lead screw 15, and the lead screw 15 is fixedly installed on the top of the mounting bracket 13. The bottom end of the lead screw 15 is connected to a bearing on the top surface of the base 1.

The lead screw 15 passes through the slider 16 and is threadedly connected to the slider 16. The left side of the suction cylinder 2 is fixedly connected to the side of the slider 16 through an L-shaped connecting rod 17.

[0037] The bottom end of the rotating shaft 4 is keyed to the shaft end of the second motor 18, and the second motor 18 is fixedly installed on the inner bottom surface of the mounting bracket 19, and the mounting bracket 19 is fixedly installed on the bottom surface of the base 1.

[0038] A drive pulley 20 is fixedly mounted on the surface of the rotating shaft 4, and the drive pulley 20 is connected to the driven pulley 22 via a belt 21.

[0040] Working principle: When in use, place the workpiece to be coated on the top surface of the worktable 5. Start the first motor 14 to drive the lead screw 15 to rotate, which causes the slider 16, which is threadedly connected to the lead screw 15, to rotate. This causes the slider 16 to drive the spray head 6 to move synchronously, thereby moving the spray head 6 to a suitable height position.

[0041] When slider 16 moves, it drives air cylinder 2 to move synchronously through L-shaped connecting rod 17. Under the sliding connection between square rod 24 and hollow tube 25, air cylinder 2 and box 26 are ensured to move synchronously, ensuring that air cylinder 2 is in the best working position.

[0042] By starting the material pump 10, the paint in the material box 3 is extracted through the material extraction pipe 11 and then sprayed onto the workpiece through the material delivery hose 12 into the nozzle 6, thereby achieving the coating of the workpiece.

[0043] At the same time, the second motor 18 is started to drive the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the worktable 5 and the workpiece to rotate synchronously, thereby ensuring comprehensive and effective coating of the workpiece.

[0044] When the rotating shaft 4 rotates, it drives the driving pulley 20 to rotate. Through the action of the belt 21, the driven pulley 22 drives the rotating rod 23 to rotate synchronously. The rotation of the rotating rod 23 drives the square rod 24 to rotate, which in turn drives the hollow tube 25 to rotate. This, in turn, drives the mounting shaft 7 and the fan blade 8 to rotate through the bevel gear set 27. This process draws the exhaust gas generated during painting into the suction cylinder 2, and then discharges it through the exhaust pipe 9 and enters the external air purification equipment for treatment via the exhaust hose. This achieves the recycling and treatment of the exhaust gas. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
