Abstract
Description
Technical Field
[0001] This utility model relates to the field of refueling equipment technology, specifically to an automatic oil cleaning device for a refueling machine flow meter. Background Technology
[0002] In existing technology, the flow meter on the fuel dispenser undergoes an oil control process after the fuel dispensing test. However, after standing for a period of time, residual test oil accumulates at the bottom of the flow meter. Before subsequent assembly at the next work station, the flow meter needs to be inverted again to drain the remaining test oil.
[0003] Currently, cleaning the flow meters of fuel dispensers requires workers to lift and tilt each meter individually, allowing the test oil to flow out from the bottom side opening, before finally placing the meter back in its original position. This method involves constant lifting, tilting, and returning, which is labor-intensive, inefficient, and results in inconsistent oil discharge rates due to varying tilt angles. Therefore, an automatic cleaning device for fuel dispenser flow meters is needed to facilitate the flow of test oil. Furthermore, this device should replace manual labor, reducing labor intensity, improving efficiency, and ensuring accurate oil discharge.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

It can process multiple flow meters at the same time, and achieves unmanned oil cleaning operation through mechanical positioning and program control, effectively improving work efficiency and consistency.
[0031] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] Example 1
[0033] This example discloses an automatic oil cleaning device for a fuel dispenser flow meter, such as... Figure 1 , 2 As shown, the system includes a transport mechanism, a clamping and rotating mechanism, and an oil receiving mechanism. The fuel dispenser flow meter is moved to the clamping and rotating mechanism via the transport mechanism, and then the clamping and rotating mechanism performs an oil-cleaning action on the flow meter, causing the oil inside the flow meter to flow into the oil receiving mechanism, thus achieving automatic oil cleaning of the fuel dispenser flow meter. The transport mechanism includes a roller conveyor 1 and a flow meter carrier 2 for placing multiple flow meters. The flow meter carrier 2 allows multiple flow meters to be transported and cleaned simultaneously on the roller conveyor 1, improving work efficiency. Preferably, the flow meter carrier 2 can hold four flow meters at a time. The roller conveyor 1 is equipped with a blocking component 3 and a positioning component 4 corresponding to the clamping and rotating mechanism. The blocking component 3 and the positioning component 4 keep the flow meter carrier 2 stationary at the clamping and rotating mechanism for rotational oil cleaning, reducing manual operation. The clamping and rotating mechanism includes a clamping component 5 and a rotating component 6 for rotating the clamping component 5. The clamping component 5 clamps the flow meter, and the rotating component 6 performs rotational oil cleaning, ensuring consistent oil cleaning across multiple flow meters and improving the automation of the device. The clamping assembly 5 is connected to the rotating assembly 6 and located above the roller conveyor 1. The rotating assembly 6 is mounted on the side of the roller conveyor 1 via a lifting mechanism 7. After the clamping assembly 5 clamps the flow meter, the rotating assembly 6 is raised and rotated via the lifting mechanism 7 to ensure the normal rotation of the flow meter and guarantee operational safety. The oil receiving mechanism 8 is located below the roller conveyor 1 and corresponds to the clamping and rotating mechanism, allowing the oil in the flow meter to be guided into the oil receiving mechanism for storage, reducing environmental pollution and ensuring green construction.
[0034] Furthermore, such as Figure 2 , 3As shown, the blocking component 3 and the positioning component 4 are mounted below the rollers of the roller conveyor 1 via a mounting plate 9. The mounting plate 9 provides a mounting platform for the blocking component 3 and the positioning component 4, ensuring the stability of the components. The flowmeter carrier 2 has an oil flow groove 10 that corresponds to the oil outlet of the flowmeter, allowing the oil in the flowmeter to be guided into the oil receiving mechanism through the oil flow groove 10 when it flows out. The flowmeter carrier 2 has positioning slots 11 on both sides for positioning the clamping and rotating mechanism. The positioning slots 11 facilitate the positioning of the flowmeter carrier 2 with the clamping and oil receiving mechanism, ensuring the accurate execution of the clamping and rotating mechanism on the flowmeter.
[0035] Furthermore, such as Figure 3 As shown, the blocking assembly 3 includes a vertical cylinder 12 and a blocking member 13. The blocking member 13 can extend from the gap between the rollers of the roller conveyor 1 via the vertical cylinder 12 and block the flow meter carrier 2 and the flow meter. The blocking assembly 13 keeps the flow meter carrier 2 within the working range of the clamping and rotating mechanism, ensuring that the clamping and rotating mechanism accurately clamps and rotates the flow meter.
[0036] Furthermore, such as Figure 3 As shown, the positioning component 4 includes symmetrically arranged transverse cylinders 14 on the mounting plate 9. The transverse cylinders 14 correspond to the clamping and rotating mechanism. A positioning plate 15 is provided at the free end of the transverse cylinder 14. The positioning plate 15 extends from the gap between the rollers of the roller conveyor 1 to position the obstructed flowmeter carrier 2. Preferably, the positioning plate 15 is located on both sides of the obstructed flowmeter carrier 2. The positioning plate 15 performs transverse positioning of the flowmeter carrier 2 through the transverse cylinder 14. Specifically, when the flowmeter and flowmeter carrier 2 are transported to the clamping and rotating mechanism, the blocking member 13 rises through the vertical cylinder 12 to intercept the flowmeter carrier 2; the positioning plate 15 clamps and positions both sides of the flowmeter carrier 2 by the retraction of the transverse cylinder 14, ensuring operational accuracy. After the flowmeter performs an oil-cleaning action at the clamping and rotating mechanism, the blocking member 13 descends through the vertical cylinder 12, and the positioning plate 15 moves away from both sides of the flowmeter carrier 2 by the extension of the transverse cylinder 14; then... The flow meter and flow meter carrier 2 are transported away via roller conveyor 1.
[0037] Example 2
[0038] This example discloses an automatic oil cleaning device for a fuel dispenser flow meter, which is further optimized based on Embodiment 1, such as... Figure 4 , 5 As shown, the rotating assembly 6 includes rotating motors 16 symmetrically arranged on both sides of the roller line 1. The rotating motors 16 rotate the clamping assembly 5 to a certain angle for static oil discharge. The rotating motors 16 are connected to the lifting mechanism 7, and the rotating motors 16 are raised and lowered by the lifting mechanism 7, thereby ensuring the normal operation of the flow meter rotation.
[0039] Furthermore, such as Figure 4 As shown, the lifting mechanism 7 includes a mounting frame 17 and a lifting cylinder 18. The lifting cylinder 18 is fixed to the mounting frame 17 by an L-shaped mounting plate 19 to ensure the stability of the lifting cylinder 18 during installation. The free end of the lifting cylinder 18 is connected to a rotary motor 16. The lifting cylinder 18 causes the rotary motor 16 to drive the clamping assembly 5 to lift the flow meter carrier, ensuring the normal operation of the clamping assembly 5.
[0040] Furthermore, such as Figure 4 As shown, the clamping assembly 5 includes a U-shaped plate 21, a positioning telescopic cylinder 22, and a pressing cylinder 23. Specifically, the concave side of the U-shaped plate can accommodate the flow meter and the flow meter carrier 2. The opening of the U-shaped plate 21 faces downwards, corresponding to the flow meter carrier 2. Both sides of the U-shaped plate 21 are connected to the rotating shaft of the rotary motor 16, enabling the rotary motor 16 to drive the U-shaped plate 21 to rotate. The positioning telescopic cylinder 22 is disposed on both sides of the U-shaped plate 21. The free end of the positioning telescopic cylinder 22 is provided with a positioning block 20, which corresponds to the positioning slot 11 of the flow meter carrier 2, so that the flow meter carrier 2 can be positioned inside the U-shaped plate 21. The pressing cylinder 23 is disposed through the top surface of the U-shaped plate 21. The free end of the pressing cylinder 23 is connected to a pressing plate 24 for pressing the flow meter. The clamping between the flow meter carrier 2 and the pressing plate 24 ensures the stability of the flow meter within the U-shaped plate 21. Specifically, once the flow meter carrier is positioned at the clamping and rotating assembly, the lifting cylinder 18 lowers and positions the clamping assembly 5 and the rotating assembly 6. After the U-shaped plate 21 covers the flow meter and the flow meter carrier 2, the positioning block 20 is inserted into the positioning slot 11 via the positioning telescopic cylinder 22, ensuring precise positioning of the U-shaped plate 21 on the flow meter carrier 2. Then, the pressing cylinder 23 lowers the pressing plate 24, stably fixing the flow meter within the U-shaped plate 21. Finally, the lifting cylinder 18 raises the U-shaped plate 21, and the rotary motor 16 rotates the U-shaped plate, causing the flow meter to rotate to a certain angle and allow it to settle and drain oil.
[0041] Furthermore, such as Figure 4 As shown, the lower pressure cylinder 23 is fixed to the top surface of the U-shaped plate 21 by a connecting plate 25, ensuring a stable connection of the lower pressure cylinder 23. The top surface of the U-shaped plate 21 is provided with a sliding bearing 26 and a sliding column 27 disposed within the sliding bearing 26. The sliding column 27 penetrates the U-shaped plate 21 and connects to the lower pressure plate 24. Preferably, the sliding bearing 26 and the sliding column 27 are symmetrically arranged at both ends of the lower pressure plate 24 to ensure uniform force distribution on the lower pressure plate 24, increase the pressure and fixation of the flow meter, and improve safety.
[0042] Example 3
[0043] This example discloses an automatic oil cleaning device for a fuel dispenser flow meter, which is further optimized based on Embodiment 1, such as... Figure 5As shown, the oil receiving assembly includes an oil receiving trough 28 and an oil receiving bucket 29. The oil receiving trough 28 is horizontally positioned below the rollers of the roller conveyor 1 and corresponds to the clamping and rotating mechanism. This allows the oil inside the flow meter to be guided into the oil receiving trough 28 through the oil flow channel 10 of the flow meter carrier 2 when the flow meter is rotating or stationary, preventing oil leakage from the flow meter. One end of the oil receiving trough 28 is connected to the inlet of the oil receiving bucket 29, which stores the flowing oil and ensures a safe working environment.
