It is mainly used to evenly apply lubricating oil, rust-preventive oil or other liquid media to the surface of objects to meet specific process requirements, ensure the lubrication, rust prevention or surface treatment effect of the workpiece, thereby improving production efficiency and product quality. It usually adopts a single air duct structure to cool and dry the oiled workpiece.

[0003] In existing technologies, the traditional single-duct structure in oiling machines results in uneven cooling, leading to significant temperature differences on the workpiece surface and affecting coating quality; the drying speed is slow, extending the production cycle and reducing production efficiency.

[0004] Therefore, this utility model provides a two-stage secondary air structure for a vertical oiling machine. Utility Model Content

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The vertical oiling machine of this utility model has a two-stage secondary air structure, including a first air duct, a centrifugal fan fixedly connected to one end of the first air duct, the output end of the centrifugal fan connected to the first air duct, a second air duct fixedly connected to the end of the first air duct away from the centrifugal fan, a third air duct fixedly connected to the bottom end of the second air duct, a third air duct fixedly connected to the first air duct, a first pneumatic butterfly valve fixedly installed on the first air duct, a second pneumatic butterfly valve fixedly installed on the third air duct, and manual butterfly valves fixedly installed at both ends of the third air duct.

[0007] Preferably, a first perforated plate is fixedly installed on the first air duct, and a second perforated plate is fixedly installed on the third air duct.

[0008] Preferably, a first differential pressure sensor is fixedly installed on the first air duct, and a second differential pressure sensor is fixedly installed on the third air duct.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The vertical oiling machine of this utility model features a two-stage secondary air structure. By setting up two independent air ducts, a first air duct and a third air duct, the user can select the appropriate air duct according to the shape of the workpiece and the oiling area. For example, for workpieces with a larger area, the first air duct can be selected; for workpieces with a smaller area, the third air duct can be selected. This design allows the airflow to be distributed more evenly on the workpiece surface, thereby achieving a more uniform cooling effect.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4As shown in the figure, a two-stage secondary air structure for a vertical oiling machine according to an embodiment of the present invention includes a first air duct 1, a centrifugal fan 2 fixedly connected to one end of the first air duct 1, the output end of the centrifugal fan 2 connected to the first air duct 1, a second air duct 3 fixedly connected to the end of the first air duct 1 away from the centrifugal fan 2, a three-stage ventilation duct 4 fixedly connected to the bottom end of the second air duct 3, a third air duct 12 fixedly connected to the first air duct 1, a first pneumatic butterfly valve 5 fixedly installed on the first air duct 1, a second pneumatic butterfly valve 6 fixedly installed on the third air duct 12, and manual butterfly valves 7 fixedly installed on both transverse ends of the three-stage ventilation duct 4.

[0023] During operation, by setting up two independent air ducts, the first air duct 1 and the third air duct 12, users can select the appropriate air duct based on the shape of the workpiece and the area to be coated. For example, for workpieces with a larger area, the first air duct 1 can be selected; for workpieces with a smaller area, the third air duct 12 can be selected. This design allows the airflow to be distributed more evenly on the workpiece surface, thereby achieving a more uniform cooling effect. The mutually exclusive control logic of the first pneumatic butterfly valve 5 and the second pneumatic butterfly valve 6 ensures that the airflow passes through only one air duct, avoiding uneven cooling caused by airflow splitting. Users can flexibly switch air ducts according to actual needs to further optimize the cooling effect.

[0024] A first perforated plate 10 is fixedly installed on the first air duct 1, and a second perforated plate 11 is fixedly installed on the third air duct 12.

[0025] During operation, the use of orifice plates ensures the stability and measurability of airflow, and improves the uniformity and consistency of the oiling process.

[0026] A first differential pressure sensor 8 is fixedly installed on the first air duct 1, and a second differential pressure sensor 9 is fixedly installed on the third air duct 12.

[0027] During operation, the differential pressure sensor can monitor the airflow in the duct in real time, ensuring that the air volume is stable and meets the process requirements during the oiling process. Through the feedback adjustment mechanism, the air volume is automatically controlled, reducing manual intervention and improving production efficiency and oiling quality.

[0028] Centrifugal fan 2 is a power adjustable fan.

[0029] During operation, by adjusting the fan power according to actual needs, unnecessary energy consumption is avoided, production costs are reduced, and the air volume can be dynamically adjusted according to different process requirements, thus improving the adaptability and flexibility of the equipment.

[0030] The inner walls of both the first duct 1 and the third duct 12 are coated with an anti-corrosion coating.

[0031] During operation, the use of anti-corrosion coating improves the reliability and stability of the equipment, reduces equipment failures caused by corrosion, effectively prevents oil mist from corroding the inner wall of the duct, extends the service life of the duct, and reduces equipment maintenance costs.

[0032] The first air duct 1, the second air duct 3, the third air duct 12, and the third air duct 4 are all made of metal.

[0033] During operation, the use of metal materials ensures the structural stability of the duct, maintaining good performance even under high pressure and high flow rates. The use of metal materials also improves the safety of the equipment and reduces safety hazards caused by material aging or damage.

[0034] Working Principle: Centrifugal fan 2 serves as the power source for the entire duct system. Its output end is connected to the first duct 1, providing airflow power for the entire duct system. The first duct 1 is connected to the three-way ventilation duct 4 via the second duct 3, forming the main duct. Simultaneously, the first duct 1 is connected to the third duct 12, serving as a branch duct. A first pneumatic butterfly valve 5 is installed on the first duct 1 to control the airflow in the main duct; a second pneumatic butterfly valve 6 is installed on the third duct 12 to control the airflow in the branch duct. By controlling the opening and closing of these two pneumatic butterfly valves, the airflow can be selected to pass through the main duct or the branch duct. Manual butterfly valves 7 are installed at both ends of the three-way ventilation duct 4 to further adjust the airflow distribution and flow rate. The manual butterfly valves 7 can be fine-tuned according to actual needs. A first orifice plate 10 and a second orifice plate 11 are respectively installed on the first duct 1 and the second duct 3 to generate a pressure difference in the main duct, facilitating the measurement of airflow flow by the differential pressure sensor. A first differential pressure sensor 8 is installed on the first duct 1 to detect the pressure difference within the main duct. The second differential pressure sensor 9 is installed on the third duct 12 to detect the pressure difference within the branch duct. Airflow is calculated by measuring the pressure difference across the orifice plate. The differential pressure sensor feeds back the detected pressure difference signal to the control unit, which adjusts the power of the centrifugal fan 2 according to set parameters, thereby achieving precise control of the airflow. The inner walls of the first duct 1 and the third duct 12 are coated with an anti-corrosion coating. During the oiling process, oil mist may corrode the inner walls of the ducts; the anti-corrosion coating effectively prevents this corrosion and extends the service life of the ducts. The first duct 1, the second duct 3, the third duct 12, and the three-way ventilation duct 4 are all made of metal. Metal materials have high strength, wear resistance, and corrosion resistance, and can withstand the impact of oil mist and airflow generated during the oiling process.
