Description

Technical Field

[0001] This utility model relates to the field of lubrication technology for textile machinery, specifically to a lubrication pump for independent oil supply to the upper and lower shafts of a textile machine. Background Technology

[0002] In the lubrication system of textile machinery, a single lubrication pump typically supplies oil to one machine. However, a single pump usually has only one output line, which is insufficient for some textile equipment with separate upper and lower shafts. Taking an embroidery machine's upper and lower shafts as an example, after the lubrication pump outputs lubricating oil, it is distributed to the lubrication points of the upper and lower shafts via a distributor. This would allow a single pump to supply oil to both shafts simultaneously. However, in practice, the lubrication needs of the upper and lower shafts are not synchronized, easily leading to lubricating oil waste and over-lubrication. Furthermore, existing oil pump output lines are relatively complex, often passing through components above the cover plate, which can easily cause oil contamination on these components, making cleaning difficult.

[0019] 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.

[0020] Example: A lubrication pump for independent oil supply to the upper and lower shafts of a textile machine, see reference. Figure 1-3 It includes an oil tank 1 and a cover plate 2 covering the top of the oil tank. The cover plate 2 is equipped with a first gear pump 21 and a second gear pump 22, which supply oil to the upper shaft and the lower shaft of the textile machine, respectively.

[0021] The first gear pump 21 and the second gear pump 22 are respectively composed of a motor 3 and a pump body 4. The motor 3 is fixedly installed above the cover plate 2, and the pump body 4 is fixedly installed below the cover plate 2. The internal structure of the pump body 4 is similar to that of an existing gear pump, with a pair of meshing gears, one side being the oil inlet and the other side being the oil outlet. The output shaft of the motor 3 passes through the cover plate 2 and connects to the drive gear inside the pump body 4. The motor 3 drives the drive gear to rotate, thereby driving the gear pump to work.

[0022] In the above structure, the oil inlet end of the pump body 4 is connected to a flexible hose, with the free end of the hose hanging down to the bottom of the oil tank for easy oil pump intake; the oil outlet end of the pump body 4 is connected to an oil outlet connector 5 located on the side edge of the cover plate 2 via a pipe. The side edge of the cover plate 2 is provided with two oil outlet connectors 5, which are respectively connected to the pump bodies of two gear pumps.

[0023] Specifically, the oil outlet connector 5 is integrally formed on the cover plate 2. Its internal channel has a horizontal T-shaped tee structure, and its outer end is connected to the lubrication part of the textile equipment through a pipe. The oil inlet end 51 of the oil outlet connector penetrates downward through the cover plate and is connected to the oil outlet end of the pump body 4 through a pipe. The other end is connected to a pressure gauge 52 for easy monitoring of oil pressure. When the gear pump of this embodiment is working, the lubricating oil is pumped by the pump body 4 to the oil outlet connector 5 integrally set on the edge of the cover plate, and the oil passage is basically confined within the oil tank 1.

[0024] In this embodiment, the cover plate 2 is also provided with a motor protective cover 6. The motors 3 of the two gear pumps are both covered inside the motor protective cover 6. The outer surface of the motor protective cover 6 is also provided with control buttons 61 for controlling the operation of the first gear pump and the second gear pump, and display screens 62 for displaying the operating status of the first gear pump and the second gear pump, respectively. The control buttons 61 and the display screens 62 are electrically connected to the motors of the two gear pumps, respectively.

[0025] In this embodiment, the cover plate 2 is provided with an oil filling port 7, and a cylindrical filter screen 71 is provided below the oil filling port 7 for filtering the lubricating oil added to the oil tank.

[0026] In this embodiment, a liquid level sensor 8 is provided on the lower end face of the cover plate 2, which is suspended in the oil tank.
