Description

Technical Field

[0001] This utility model relates to the field of textile machinery lubrication technology, specifically to an oil and gas output unit and an oil and gas supply system for textile machinery lubrication. Background Technology

[0002] Existing spray lubrication systems for textile machinery require separate control for lubrication of different machines. Specifically, multiple oil and air supply lines need to be drawn from the oil pump and air source, and controlled separately, making the entire system overly complex. Furthermore, in current spray lubrication systems, oil-air mixing is generally completed in the oil reservoir. For example, Chinese utility model patent CN220927169U discloses a novel adjustable multi-head atomizing lubrication device that injects oil and air separately into the reservoir to form an oil-air mixture. However, this reservoir is large and has many external components, such as solenoid valves, which occupy a lot of space, are not aesthetically pleasing, and prolonged exposure affects service life, while also increasing costs.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following embodiments will provide a more detailed description of this utility model.

[0023] Example

[0024] Reference Figure 1-5This embodiment provides an oil and gas supply system, including an oil pump and a gas source. The output end of the oil pump is connected to a main oil pipe 200, and the output end of the gas source is connected to a main gas pipe 100. Multiple oil and gas output units 300 are connected in series on the main oil pipe 200 and the main gas pipe 100, respectively corresponding to multiple textile machines.

[0025] In the above structure, the oil and gas output unit 300 includes a box body 1 and two oil and gas spray modules 2 integrally formed in the box body. The top of the box body 1 is provided with a box cover, and the bottom of the box body is provided with an oil passage 3 and an air passage 4. The two ends of the oil passage 3 are connected to the main oil pipe 200, and the two ends of the air passage 4 are connected to the main air pipe 100, so that the main oil pipe 200 and the main air pipe 100 pass through each oil and gas output unit 300, and can supply oil and gas to each oil and gas output unit 300.

[0026] The oil-gas spray module 2 is roughly tubular, consisting of an oil chamber 5 and an air chamber 6. The oil chamber 5 is connected to the oil passage 3, and the air chamber 6 is connected to the air passage 4 via a solenoid valve 7. The solenoid valve 7 controls the intake of air into the air chamber 6. Specifically, the oil passage 3 and the oil chamber 5 each have corresponding openings. After the oil-gas spray module 2 is installed inside the housing 1, the two are sealed together. The air passage 4 also has an opening corresponding to and connected to the air inlet of the solenoid valve 7, and the air outlet of the solenoid valve 7 is connected to the air chamber 6.

[0027] In addition, an indicator light 500 is provided on the housing 1 to display the working status of the solenoid valve 7. The working status of the solenoid valve 7 can be observed intuitively. When the solenoid valve 7 is energized, the indicator light is on, and when the solenoid valve 7 is de-energized, the indicator light is off.

[0028] In this embodiment, two oil-air spray modules 2 are arranged side by side and integrally formed. The air chambers 6 of the two oil-air spray modules 2 are interconnected, and air is supplied to both air chambers simultaneously through the operation of a solenoid valve 7. An air outlet pipe 8 is connected to the outlet end of the air chamber 6, and the other end of the air outlet pipe 8 is connected to a nozzle located at the lubrication point of the textile machine.

[0029] Two oil spray modules 2 are just enough to simultaneously and separately lubricate the upper and lower heads of a textile machine, such as an embroidery machine.

[0030] The oil chamber is equipped with a metering element 10. In this embodiment, the metering element is the anti-backflow metering element disclosed in the utility model patent with publication number CN219640010U previously filed by the applicant. It can accurately dispense oil. Since it is prior art, its specific structure and principle will not be described in detail in this embodiment. Specifically, the outlet end of the metering element 10 is connected to an oil outlet rod 11. An opening is provided between the oil chamber 5 and the gas chamber 6. After the oil outlet rod 11 passes through the opening (while the opening is sealed), it passes through the gas chamber 6 and extends into the gas outlet pipe 8. Then, an oil outlet pipe 9 is connected to the end of the oil outlet rod 11. The outer diameter of the oil outlet pipe 9 is smaller than the inner diameter of the gas outlet pipe 8. In this embodiment, the gas outlet pipe 8 is an 8mm pipe and the oil outlet pipe 9 is a 4mm pipe, so that the oil outlet pipe 9 is accommodated in the gas outlet pipe 8. The length of the oil outlet pipe 9 is about 10cm shorter than that of the gas outlet pipe 8, so that an oil-gas mixing area of ​​about 10cm in length is formed at the tail end of the gas outlet pipe 8.

[0031] A plug 12 is installed at the outer end of the oil chamber 5. The plug 12 seals the oil chamber and fixes and supports the quantitative measuring element 10.

[0032] In this embodiment, during lubrication, the oil pump supplies oil to the oil chamber 5. When the oil pressure in the oil chamber 5 rises, the lubricating oil enters the metering device 10, and the metering device 10 discharges a metered amount of oil from the oil outlet pipe 9. At the same time, the solenoid valve 7 operates to open the air passage of the air chamber 6, and the oil and gas merge at the end of the air outlet pipe 8. Under the action of air pressure, an oil-gas mixture is formed, which then performs fixed-point metered spray lubrication on the textile machine.

[0033] Furthermore, the main air pipe 100 and main oil pipe 200 in this embodiment are also equipped with an oil and air pressure detection unit 400. The oil and air pressure detection unit 400 can adopt the same shell structure as the oil and gas output unit to save mold costs. An air pressure detection sensor is connected to the air passage of the oil and air pressure detection unit 400, and an oil pressure detection device is connected to the oil passage, so that the oil and air pressure can be monitored in real time.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
