Description

Technical Field

[0001] This utility model relates to the field of mechanical lubrication technology, and more specifically, to a micro-lubricating oil supply device for automatic conveyor lines with conveyor belts. Background Technology

[0002] In modern manufacturing industries such as electric motor stamping, automatic conveyor lines for conveying materials need to continuously and stably supply a small amount of lubricating oil to their roller parts to reduce frictional wear between the conveyor belt and the rollers, prevent the stamping plates from rusting, and avoid wear during high-speed stamping.

[0003] Currently, there are two main known methods of oil supply: one is to equip a dedicated hydraulic station, which is complex and requires electric drive, resulting in high cost and low energy efficiency when used in micro-oil supply scenarios; the other is to use simple gravity oil supply, which has low oil supply pressure, and the oil storage bottle is easily affected by strong vibration near the high-speed punch press, leading to unstable oil supply and affecting the uniformity of lubrication effect.

[0004] Therefore, there is an urgent need for a stable micro-oil supply device that is simple in structure, low in cost, and unaffected by environmental vibrations. Summary of the Invention

[0005] This utility model aims to solve the technical problems of complex and expensive hydraulic station oil supply methods and unstable and easily interfered gravity oil supply methods in the prior art, and provides a simple micro-oil supply device that utilizes the existing air source in the factory, has a simple and reasonable structure, and is stable and reliable in operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a simple micro-oil supply device, comprising a gas pipeline, an oil pipeline, a fully enclosed oil tank, and an oil delivery hose.

[0007] Preferably, the inlet end of the gas supply pipe is used to connect to a plant compressed air source, and its outlet end is connected to the upper space inside the fully enclosed oil tank. A first ball valve, an air filter, a pressure regulating valve, and a second ball valve are sequentially arranged on the gas supply pipe along the inlet direction.

[0008] Preferably, the inlet end of the oil delivery pipe extends into the bottom of the fully enclosed oil tank, and its outlet end is connected to the lubricating oil distributor via the oil delivery hose. A lubricating oil filter, a third ball valve, and a flow regulating valve are sequentially arranged on the oil delivery pipe along the oil outlet direction.

[0009] Preferably, the fully enclosed oil tank is provided with an oil filling port and a safety vent valve at the top, a liquid level sight glass on the side, and an oil drain valve at the bottom.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Simple structure and low cost: It makes full use of the compressed air widely available in the factory as a power source, without the need for additional electric drive or complex hydraulic system, which greatly reduces equipment cost and operating energy consumption; 2. Stable and reliable operation: Compressed air can provide stable and adjustable pressure to drive the flow of lubricating oil, completely overcoming the shortcomings of insufficient pressure from gravity oil supply and susceptibility to equipment vibration, ensuring the uniformity and continuity of lubrication. 3. Easy maintenance: The installation of air and lubricating oil filters ensures the cleanliness of the medium; the oil level can be directly observed through the level sight glass; and all valves are easy to control and maintain.

[0013] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and embodiments.

[0014] See Figure 1 The present invention provides a simple micro-oil supply device, which is mainly composed of an air circuit, an oil tank, and an oil circuit connected in series.

[0015] The air circuit includes an air supply pipe 1, and a first ball valve 6, an air filter 7, a pressure regulating valve 8, a pressure gauge 9, and a second ball valve 10, which are installed sequentially along the airflow direction. The air inlet of the air supply pipe 1 serves as the air source 5 interface and can be connected to the plant compressed air system via a quick-connect coupling; its outlet extends into the upper part of the fully enclosed oil tank 3, and the port is located above the liquid surface of the lubricating oil 16.

[0016] The core of the oil tank section is a fully enclosed oil tank 3. This oil tank 3 is a sealed tank conforming to pressure vessel specifications. Its top is equipped with an oil inlet 14 with a sealed blind flange and a safety vent valve 15 (preferably a pressure relief valve). A level gauge 18 for observing the oil level is installed on the side. An oil drain valve 17 is located at the bottom. The lower part of the tank stores lubricating oil 16, and the upper part is a compressed air chamber.

[0017] The oil circuit includes an oil delivery pipe 2, and a lubricating oil filter 11, a third ball valve 12, and a flow regulating valve 13, which are sequentially installed along the oil flow direction. The oil inlet end of the oil delivery pipe 2 extends into the bottom of the fully enclosed oil tank 3, with its port close to the bottom surface of the inner cavity, below the surface of the lubricating oil 16. The oil outlet end of the oil delivery pipe 2 is connected to an oil delivery hose 4, the end of which is used to connect to a lubricating oil distributor on an automatic conveyor line.

[0018] In this embodiment, threaded connections are preferably used between the components for ease of installation and maintenance. The air filter 7, pressure regulating valve 8, and pressure gauge 9 can be integrated into a known pneumatic triplet. The safety vent valve 15 is preferably a pressure safety valve that automatically opens in case of overpressure. The pressure regulating valve 8 can be a two-way pressure regulating valve, which can maintain pressure in the oil tank 3 and downstream pipelines when the first ball valve 6 is closed.

[0019] The working principle of this utility model is briefly described as follows: The first ball valve 6 and the second ball valve 10 are opened. The factory compressed air, after being purified by the air filter 7 and pressure adjusted by the pressure regulating valve 8, enters the upper part of the fully enclosed oil tank 3, applying stable pressure to the lubricating oil 16. The pressurized lubricating oil 16 flows out through the oil delivery pipe 2, passes through the lubricating oil filter 11 for filtration, and the flow rate is precisely adjusted by the flow regulating valve 13. Finally, it is delivered to the lubricating oil distributor via the oil delivery hose 4, and is uniformly and stably dripped onto the parts requiring lubrication.

[0020] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
