For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1 As shown, the first embodiment of this utility model provides a progressive drawing metal sheet oiling device based on the prior art, including an automatic spraying oil pump system 1, which is connected to a spraying device 3 through a pipeline 2. The automatic spraying oil pump system 1 is used to provide the spraying device 3 with a gas-liquid mixture of oil with an uninterrupted and balanced oil source. The spraying device 3 is used to apply oil to the feed belt. A drawing oil collection tank 4 is installed at the lower part of the spraying device 3. The specific structure of each component and the connection relationship between them will be described in detail below.

[0023] like Figure 2 As shown, the spraying device 3 includes two symmetrically arranged bottom oiling frames 38. A passive oiling roller 36 is rotatably mounted between the two bottom oiling frames 38. Each of the two bottom oiling frames 38 is connected to a top oiling frame 34 via two connecting rods 32. Oiling machine cylinders 33 are respectively installed on the top of each of the two top oiling frames 34. The actuators of the two oiling machine cylinders 33 are rotatably connected to both ends of a drive oiling roller 35. A drive reduction motor 37 is installed on one side of either of the two top oiling frames 34. The actuator of the drive reduction motor 37 is coaxially arranged with one end of the drive oiling roller 35. The two bottom oiling frames 38, four connecting rods 32, and two top oiling frames 34 are installed inside a protective cover 31.

[0024] like Figure 3As shown, the automatic spraying oil pump system 1 includes an oil tank 11, which is connected to two SC10-5000W202 pneumatic pumps 12. The two SC10-5000W202 pneumatic pumps 12 are respectively connected to the air source control system 17. The two SC10-5000W202 pneumatic pumps 12 are respectively connected to the delivery pipeline valve 16 through the flow control valve 13. The air source control system 17 is connected to the booster regulator 15. The booster regulator 15 is connected to the gas-liquid mixer 4. The delivery pipeline valve 16 is respectively connected to the gas-liquid mixer 14 and the drawing oil collection tank 4. The gas-liquid mixer 14 is respectively connected to the passive oiling roller 36 and the active oiling roller 35.

[0025] The two pneumatic pumps 12 operate as follows: air is supplied to the pneumatic pumps 12 by a diaphragm valve through timing control, and the air flow of the pneumatic pumps is controlled by a needle-type air source control valve to eliminate the phenomenon of pneumatic pump stop delay. When the 1# diaphragm valve is energized, the 1# pneumatic pump operates for 2-3 seconds, and the 2# diaphragm valve is energized to start the 2# pump. When the 1# pump sucks oil, the 2# pump pressurizes oil, and when the 2# pump sucks oil, the 1# pump pressurizes oil. The needle-type air source control valve adjusts the action sequence and overlapping area of ​​the two pumps, thus solving the problem of pulsed oil source. Oil at a certain pressure enters the flow control valve through the pipeline to realize the flow adjustment and back pressure effect. The oil enters the constant pressure gas-liquid mixer, where the oil mixes with the constant pressure gas to form a stable gas-liquid mixture. The uniform gas-liquid mixture enters the micro pressure roller brush coating device.

[0026] The pneumatic pump power unit operates by extending and retracting a cylinder, driving a plunger pump to draw in and pressurize oil. This oil is pulsating. Two pumps work in tandem: the first pump draws in oil while the second presses, and vice versa. Coordinated operation is achieved using a needle-type pneumatic control valve, and this cycle continues. This eliminates pulsating oil sources, ensuring a continuous, balanced, and stable oil supply, avoiding the defects caused by intermittent pulsed oil sources. The oil then flows through pipelines to a flow valve, which acts as a filter, further stabilizing the flow and pressure. It then enters the gas-liquid mixing chamber, where constant-pressure compressed air and stabilizing drawing oil are thoroughly mixed to form a homogeneous gas-liquid mixture before entering the spraying device. The constant-pressure compressed air is provided by a booster; after entering the booster, the compressed air is pressurized to form a stable constant-pressure air supply.

[0027] The oil enters the rotary sealing valve through a pipeline, and then flows into a roller with a grooved nozzle. A drive reduction motor 37 drives the active oiling roller 35, which, under pressure from the oiling machine cylinder 33, presses the steel strip and rolls, spraying the oil onto the steel strip surface. Simultaneously, the passive oiling roller 36, driven by the belt, also rolls and brushes the oil. This system allows the active and passive oiling rollers 35 and 36 to simultaneously brush the upper and lower surfaces of the strip with drawing oil. The rolling motion of the active and passive oiling rollers with the strip ensures that the oil is evenly applied to the strip surface, forming a dense oil film.

[0028] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art.
