Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment processing technology, specifically to a spraying device for the production of hydraulic mechanical equipment that facilitates the removal of odors. Background Technology
[0002] Hydraulic machinery uses fluid energy as its working medium. A hydraulic pump converts the mechanical energy of a power source into the pressure energy of hydraulic oil. This hydraulic oil, under high pressure, is then transmitted to the actuator, such as a hydraulic cylinder, where the pressure energy is converted back into mechanical energy, thus achieving linear or rotary motion. During the production process, the outer shell of the hydraulic cylinder is typically coated for protection. However, existing coating systems for hydraulic equipment still have certain shortcomings, such as:
[0003] The patent application CN202022431313.6, entitled "A Spraying Device for Mechanical Equipment Processing," cannot handle the odor during spraying, which affects the production environment and endangers the health of workers. Furthermore, it can only spray the upper surface of the mechanical equipment, failing to effectively spray the sides, thus affecting the spraying effect. Additionally, it cannot agitate the coating, making it difficult to achieve uniformity and impacting the production quality of hydraulic machinery, thus limiting its application. Therefore, this paper proposes a spraying device for hydraulic machinery production that easily removes odors to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for the production of hydraulic mechanical equipment that facilitates the removal of odors, comprising a spraying chamber and a sealing door rotatably connected to its side wall;
[0006] A through-pipe is installed through the central longitudinal bearing at the top of the spraying chamber, and a spray pipe is fixedly connected to the bottom of the through-pipe. Spray nozzles are evenly installed on the inner side wall of the spray pipe. A support filter plate is fixedly installed on the inner wall of the spraying chamber, and the support filter plate is located below the spray pipe. A material box is fixedly installed on the left side of the spraying chamber, and a stirring rod is installed through the central longitudinal bearing at the top of the material box. Stirring blades are evenly installed on the surface of the stirring rod, and the stirring blades are located inside the material box. An exhaust fan is fixedly installed on the top surface of the spraying chamber, and the exhaust fan inlet pipe is fixedly connected to the top of the spraying chamber. The exhaust fan outlet pipe is connected to an air purification device fixedly installed on the right side of the spraying chamber. A material conveying structure connected to the through-pipe is provided on the top surface of the material box.
[0007] The above technical solution facilitates the removal of odors during the spraying of hydraulic machinery and equipment, and improves the spraying effect to ensure uniformity.
[0008] As a preferred technical solution of this utility model, a guide hopper is fixedly installed on the inner wall of the spraying chamber, and the guide hopper is located below the supporting filter plate. A collection box is provided below the supporting filter plate, and the collection box is movably placed on the inner bottom surface of the spraying chamber.
[0009] The above technical solution facilitates the collection of waste materials dripping from the spraying process.
[0010] As a preferred embodiment of the present invention, the material conveying structure includes a material pump fixedly installed on the top surface of the material box. The inlet end of the material pump is fixedly connected to one end of the inlet pipe, and the other end of the inlet pipe is fixedly connected to the lower end of the left side wall of the material box. The outlet end of the material pump is fixedly connected to one end of the outlet pipe, and the other end of the outlet pipe is connected to the top end of the through pipe through a rotary joint.
[0011] The above technical solution facilitates the pumping of paint through the nozzle for spraying.
[0012] As a preferred technical solution of this utility model, a fixed frame is fixedly installed on the top surface of the spraying chamber, and the discharge pipe is longitudinally fixedly installed through the top of the fixed frame. A motor is fixedly installed on the top surface of the fixed frame, and a rotating shaft is keyed to the shaft end of the motor. A longitudinal bearing of the rotating shaft is installed through the top of the fixed frame, and a turntable is coaxially fixedly installed at the bottom end of the rotating shaft. A cylindrical pin is fixedly installed at an eccentric position on the bottom surface of the turntable.
[0013] The above technical solution facilitates the rotation of the rotating shaft by a motor, which in turn causes the turntable to drive the cylindrical pin to rotate in a circular motion.
[0014] As a preferred technical solution of this utility model, a movable plate is slidably connected to the top surface of the spraying chamber, and a strip groove is opened on the top surface of the movable plate. The cylindrical pin extends into the strip groove, and the diameter of the cylindrical pin matches the width of the strip groove. A straight rack is fixedly installed at one end of the movable plate near the through pipe, and the straight rack is slidably connected to the top surface of the spraying chamber.

At the same time, it can agitate the coating to ensure the uniformity of the coating, improve the production quality of hydraulic machinery, and is simple and flexible to operate with strong practicality.
[0019] 1. Install an exhaust fan at the top of the spray booth, in conjunction with air purification equipment. During spraying operations, the exhaust fan draws out odor-containing air from the booth and sends it to the purification equipment for treatment. This effectively removes odors generated during the spraying process, prevents odors from spreading into the production environment, significantly improves workplace air quality, protects the health of workers, and reduces the potential adverse effects of odors on the human respiratory and nervous systems.
[0020] 2. The motor drives the rotating shaft, turntable, and eccentric cylindrical pin to rotate. The cylindrical pin moves within the groove of the moving plate, pushing the moving plate and rack to slide laterally. The rack meshes with the first gear on the through pipe, causing the through pipe to drive the spray pipe and nozzle to rotate, rotating 90° each time. This achieves effective spraying of different parts of the hydraulic machinery equipment, such as the upper surface and sides, ensuring that all parts of the equipment are evenly covered with paint, avoiding spraying dead corners, and improving the integrity and aesthetics of the coating.
[0021] 3. When the pipe rotates, the arc-shaped rack at the end of the straight rod meshes with the second gear at the top of the stirring rod, driving the stirring rod and stirring blades to agitate the coating in the tank. This prevents sedimentation and stratification of the coating during storage and use, ensures uniform coating texture, stabilizes the surface coating quality of the equipment, and improves the protective performance and service life of the hydraulic machinery.

The top surface of the material box 6 is provided with a material conveying structure connected to the through pipe 2.
[0030] A guide hopper 11 is fixedly installed on the inner wall of the spraying chamber 1, and the guide hopper 11 is located below the supporting filter plate 5. A collection box 12 is provided below the supporting filter plate 5, and the collection box 12 is movably placed on the inner bottom surface of the spraying chamber 1.
[0031] The material conveying structure includes a material pump 13 fixedly installed on the top surface of the material box 6. The inlet end of the material pump 13 is fixedly connected to one end of the inlet pipe 14, and the other end of the inlet pipe 14 is fixedly connected to the lower end of the left side wall of the material box 6. The outlet end of the material pump 13 is fixedly connected to one end of the outlet pipe 15, and the other end of the outlet pipe 15 is connected to the top end of the through pipe 2 through a rotary joint 16.
[0032] A fixed frame 17 is fixedly installed on the top surface of the spraying chamber 1, and the discharge pipe 15 is fixedly installed longitudinally through the top of the fixed frame 17. A motor 18 is fixedly installed on the top surface of the fixed frame 17, and a rotating shaft 19 is keyed to the shaft end of the motor 18.

A cylindrical pin 21 is fixedly installed at an eccentric position on the bottom surface of the turntable 20.

[0036] Simultaneously, the motor 18 is started, driving the rotating shaft 19 to rotate. The rotating shaft 19 drives the cylindrical pin 21 to rotate in a circle through the turntable 20. The cylindrical pin 21 moves in the strip groove 23 of the moving plate 22, driving the moving plate 22 and the rack 24 to move laterally. Since the rack 24 meshes with the first gear 25, it drives the through pipe 2 to rotate, and the angle of the spray pipe 3 and the nozzle 4 is adjusted accordingly, so as to spray the hydraulic mechanical equipment in a comprehensive manner.
[0037] At the same time, when the pipe 2 rotates, the straight rod 26 drives the arc rack 27 to rotate synchronously, so that the second gear 28, which meshes with the arc gear 27, drives the stirring rod 7 and the stirring blade 8 to rotate, stirring the coating in the material box 6 to ensure that the coating is uniform.
[0038] During the spraying process, the exhaust fan 9 operates to extract the odorous air from the spraying chamber 1 and send it to the air purification equipment 10 for purification. At the same time, the paint and impurities dripping during the spraying process fall into the collection box 12 through the guide hopper 11. The collection box 12 is cleaned regularly to keep the inside of the spraying chamber 1 clean. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
